Git v2.38 Release Notes
=======================
UI, Workflows & Features
* "git remote show [-n] frotz" now pays attention to negative
pathspec.
* "git push" sometimes performs poorly when reachability bitmaps are
used, even in a repository where other operations are helped by
bitmaps. The push.useBitmaps configuration variable is introduced
to allow disabling use of reachability bitmaps only for "git push".
* "git grep -m<max-hits>" is a way to limit the hits shown per file.
* "git merge-tree" learned a new mode where it takes two commits and
computes a tree that would result in the merge commit, if the
histories leading to these two commits were to be merged.
* "git mv A B" in a sparsely populated working tree can be asked to
move a path between directories that are "in cone" (i.e. expected
to be materialized in the working tree) and "out of cone"
(i.e. expected to be hidden). The handling of such cases has been
improved.
* Earlier, HTTP transport clients learned to tell the server side
what locale they are in by sending Accept-Language HTTP header, but
this was done only for some requests but not others.
* Introduce a safe.barerepository configuration variable that
allows users to forbid discovery of bare repositories.
* Various messages that come from the pack-bitmap codepaths have been
tweaked.
* "git rebase -i" learns to update branches whose tip appear in the
rebased range with "--update-refs" option.
* "git ls-files" learns the "--format" option to tweak its output.
* "git cat-file" learned an option to use the mailmap when showing
commit and tag objects.
* When "git merge" finds that it cannot perform a merge, it should
restore the working tree to the state before the command was
initiated, but in some corner cases it didn't.
* Operating modes like "--batch" of "git cat-file" command learned to
take NUL-terminated input, instead of one-item-per-line.
* "git rm" has become more aware of the sparse-index feature.
* "git rev-list --disk-usage" learned to take an optional value
"human" to show the reported value in human-readable format, like
"3.40MiB".
* The "diagnose" feature to create a zip archive for diagnostic
material has been lifted from "scalar" and made into a feature of
"git bugreport".
* The namespaces used by "log --decorate" from "refs/" hierarchy by
default has been tightened.
* "git rev-list --ancestry-path=C A..B" is a natural extension of
"git rev-list A..B"; instead of choosing a subset of A..B to those
that have ancestry relationship with A, it lets a subset with
ancestry relationship with C.
* "scalar" now enables built-in fsmonitor on enlisted repositories,
when able.
* The bash prompt (in contrib/) learned to optionally indicate when
the index is unmerged.
* "git clone" command learned the "--bundle-uri" option to coordinate
with hosting sites the use of pre-prepared bundle files.
* "git range-diff" learned to honor pathspec argument if given.
* "git format-patch --from=<ident>" can be told to add an in-body
"From:" line even for commits that are authored by the given
<ident> with "--force-in-body-from" option.
* The built-in fsmonitor refuses to work on a network mounted
repositories; a configuration knob for users to override this has
been introduced.
* The "scalar" addition from Microsoft is now part of the core Git
installation.
Performance, Internal Implementation, Development Support etc.
* Collection of what is referenced by objects in promisor packs have
been optimized to inspect these objects in the in-pack order.
* Introduce a helper to see if a branch is already being worked on
(hence should not be newly checked out in a working tree), which
performs much better than the existing find_shared_symref() to
replace many uses of the latter.
* Teach "git archive" to (optionally and then by default) avoid
spawning an external "gzip" process when creating ".tar.gz" (and
".tgz") archives.
* Allow large objects read from a packstream to be streamed into a
loose object file straight, without having to keep it in-core as a
whole.
* Further preparation to turn git-submodule.sh into a builtin
continues.
* Apply Coccinelle rule to turn raw memmove() into MOVE_ARRAY() cpp
macro, which would improve maintainability and readability.
* Teach "make all" to build gitweb as well.
* Tweak tests so that they still work when the "git init" template
did not create .git/info directory.
* Add Coccinelle rules to detect the pattern of initializing and then
finalizing a structure without using it in between at all, which
happens after code restructuring and the compilers fail to
recognize as an unused variable.
* The code to convert between GPG trust level strings and internal
constants we use to represent them have been cleaned up.
* Support for libnettle as SHA256 implementation has been added.
* The way "git multi-pack" uses parse-options API has been improved.
* A Coccinelle rule (in contrib/) to encourage use of COPY_ARRAY
macro has been improved.
* API tweak to make it easier to run fuzz testing on commit-graph parser.
* Omit fsync-related trace2 entries when their values are all zero.
* The codepath to write multi-pack index has been taught to release a
large chunk of memory that holds an array of objects in the packs,
as soon as it is done with the array, to reduce memory consumption.
* Add a level of redirection to array allocation API in xdiff part,
to make it easier to share with the libgit2 project.
* "git fetch" client logs the partial clone filter used in the trace2
output.
* The "bundle URI" design gets documented.
* The common ancestor negotiation exchange during a "git fetch"
session now leaves trace log.
* Test portability improvements.
(merge 4d1d843be7 mt/rot13-in-c later to maint).
* The "subcommand" mode is introduced to parse-options API and update
the command line parser of Git commands with subcommands.
* The pack bitmap file gained a bitmap-lookup table to speed up
locating the necessary bitmap for a given commit.
* The assembly version of SHA-1 implementation for PPC has been
removed.
* The server side that responds to "git fetch" and "git clone"
request has been optimized by allowing it to send objects in its
object store without recomputing and validating the object names.
* Annotate function parameters that are not used (but cannot be
removed for structural reasons), to prepare us to later compile
with -Wunused warning turned on.
* Share the text used to explain configuration variables used by "git
<subcmd>" in "git help <subcmd>" with the text from "git help config".
* "git mv A B" in a sparsely populated working tree can be asked to
move a path from a directory that is "in cone" to another directory
that is "out of cone". Handling of such a case has been improved.
* The chainlint script for our tests has been revamped.
Fixes since v2.37
-----------------
* Rewrite of "git add -i" in C that appeared in Git 2.25 didn't
correctly record a removed file to the index, which was fixed.
* Certain diff options are currently ignored when combined-diff is
shown; mark them as incompatible with the feature.
* Adjust technical/bitmap-format to be formatted by AsciiDoc, and
add some missing information to the documentation.
* Fixes for tests when the source directory has unusual characters in
its path, e.g. whitespaces, double-quotes, etc.
* "git mktree --missing" lazily fetched objects that are missing from
the local object store, which was totally unnecessary for the purpose
of creating the tree object(s) from its input.
* Give _() markings to fatal/warning/usage: labels that are shown in
front of these messages.
* References to commands-to-be-typed-literally in "git rebase"
documentation mark-up have been corrected.
* In a non-bare repository, the behavior of Git when the
core.worktree configuration variable points at a directory that has
a repository as its subdirectory, regressed in Git 2.27 days.
* Recent update to vimdiff layout code has been made more robust
against different end-user vim settings.
* Plug various memory leaks, both in the main code and in test-tool
commands.
* Fixes a long-standing corner case bug around directory renames in
the merge-ort strategy.
* The resolve-undo information in the index was not protected against
GC, which has been corrected.
* A corner case bug where lazily fetching objects from a promisor
remote resulted in infinite recursion has been corrected.
* "git clone" from a repository with some ref whose HEAD is unborn
did not set the HEAD in the resulting repository correctly, which
has been corrected.
* An earlier attempt to plug leaks placed a clean-up label to jump to
at a bogus place, which as been corrected.
* Variable quoting fix in the vimdiff driver of "git mergetool"
* "git shortlog -n" relied on the underlying qsort() to be stable,
which shouldn't have. Fixed.
* A fix for a regression in test framework.
* mkstemp() emulation on Windows has been improved.
* Add missing documentation for "include" and "includeIf" features in
"git config" file format, which incidentally teaches the command
line completion to include them in its offerings.
* Avoid "white/black-list" in documentation and code comments.
* Workaround for a compiler warning against use of die() in
osx-keychain (in contrib/).
* Workaround for a false positive compiler warning.
* "git p4" working on UTF-16 files on Windows did not implement
CRLF-to-LF conversion correctly, which has been corrected.
* "git p4" did not handle non-ASCII client name well, which has been
corrected.
* "rerere-train" script (in contrib/) used to honor commit.gpgSign
while recreating the throw-away merges.
* "git checkout" miscounted the paths it updated, which has been
corrected.
* Fix for a bug that makes write-tree to fail to write out a
non-existent index as a tree, introduced in 2.37.
* There was a bug in the codepath to upgrade generation information
in commit-graph from v1 to v2 format, which has been corrected.
* Gitweb had legacy URL shortener that is specific to the way
projects hosted on kernel.org used to (but no longer) work, which
has been removed.
* Fix build procedure for Windows that uses CMake so that it can pick
up the shell interpreter from local installation location.
* Conditionally allow building Python interpreter on Windows
* Fix to lstat() emulation on Windows.
* Older gcc with -Wall complains about the universal zero initializer
"struct s = { 0 };" idiom, which makes developers' lives
inconvenient (as -Werror is enabled by DEVELOPER=YesPlease). The
build procedure has been tweaked to help these compilers.
* Plug memory leaks in the failure code path in the "merge-ort" merge
strategy backend.
* "git symbolic-ref symref non..sen..se" is now diagnosed as an error.
* A follow-up fix to a fix for a regression in 2.36 around hooks.
* Avoid repeatedly running getconf to ask libc version in the test
suite, and instead just as it once per script.
* Platform-specific code that determines if a directory is OK to use
as a repository has been taught to report more details, especially
on Windows.
* "vimdiff3" regression fix.
* "git fsck" reads mode from tree objects but canonicalizes the mode
before passing it to the logic to check object sanity, which has
hid broken tree objects from the checking logic. This has been
corrected, but to help existing projects with broken tree objects
that they cannot fix retroactively, the severity of anomalies this
code detects has been demoted to "info" for now.
* Fixes to sparse index compatibility work for "reset" and "checkout"
commands.
* An earlier optimization discarded a tree-object buffer that is
still in use, which has been corrected.
* Fix deadlocks between main Git process and subprocess spawned via
the pipe_command() API, that can kill "git add -p" that was
reimplemented in C recently.
* The sequencer machinery translated messages left in the reflog by
mistake, which has been corrected.
* xcalloc(), imitating calloc(), takes "number of elements of the
array", and "size of a single element", in this order. A call that
does not follow this ordering has been corrected.
* The preload-index codepath made copies of pathspec to give to
multiple threads, which were left leaked.
* Update the version of Ubuntu used for GitHub Actions CI from 18.04
to 22.04.
* The auto-stashed local changes created by "git merge --autostash"
was mixed into a conflicted state left in the working tree, which
has been corrected.
* Multi-pack index got corrupted when preferred pack changed from one
pack to another in a certain way, which has been corrected.
(merge 99e4d084ff tb/midx-with-changing-preferred-pack-fix later to maint).
* The clean-up of temporary files created via mks_tempfile_dt() was
racy and attempted to unlink() the leading directory when signals
are involved, which has been corrected.
(merge babe2e0559 rs/tempfile-cleanup-race-fix later to maint).
* FreeBSD portability fix for "git maintenance" that spawns "crontab"
to schedule tasks.
(merge ee69e7884e bc/gc-crontab-fix later to maint).
* Those who use diff-so-fancy as the diff-filter noticed a regression
or two in the code that parses the diff output in the built-in
version of "add -p", which has been corrected.
(merge 0a101676e5 js/add-p-diff-parsing-fix later to maint).
* Segfault fix-up to an earlier fix to the topic to teach "git reset"
and "git checkout" work better in a sparse checkout.
(merge 037f8ea6d9 vd/sparse-reset-checkout-fixes later to maint).
* "git diff --no-index A B" managed its the pathnames of its two
input files rather haphazardly, sometimes leaking them. The
command line argument processing has been straightened out to clean
it up.
(merge 2b43dd0eb5 rs/diff-no-index-cleanup later to maint).
* "git rev-list --verify-objects" ought to inspect the contents of
objects and notice corrupted ones, but it didn't when the commit
graph is in use, which has been corrected.
(merge b27ccae34b jk/rev-list-verify-objects-fix later to maint).
* More fixes to "add -p"
(merge 64ec8efb83 js/builtin-add-p-portability-fix later to maint).
* The parser in the script interface to parse-options in "git
rev-parse" has been updated to diagnose a bogus input correctly.
(merge f20b9c36d0 ow/rev-parse-parseopt-fix later to maint).
* The code that manages list-object-filter structure, used in partial
clones, leaked the instances, which has been plugged.
(merge 66eede4a37 jk/plug-list-object-filter-leaks later to maint).
* Fix another UI regression in the reimplemented "add -p".
(merge f6f0ee247f rs/add-p-worktree-mode-prompt-fix later to maint).
* "git fetch" over protocol v2 sent an incorrect ref prefix request
to the server and made "git pull" with configured fetch refspec
that does not cover the remote branch to merge with fail, which has
been corrected.
(merge 49ca2fba39 jk/proto-v2-ref-prefix-fix later to maint).
* A result from opendir() was leaking in the commit-graph expiration
codepath, which has been plugged.
(merge 12f1ae5324 ml/commit-graph-expire-dir-leak-fix later to maint).
* Just like we have coding guidelines, we now have guidelines for
reviewers.
(merge e01b851923 vd/doc-reviewing-guidelines later to maint).
* Other code cleanup, docfix, build fix, etc.
(merge 77b9e85c0f vd/fix-perf-tests later to maint).
(merge 0682bc43f5 jk/test-crontab-fixes later to maint).
(merge b46dd1726c cc/doc-trailer-whitespace-rules later to maint).

Git 2.36 Release Notes
======================
Updates since Git 2.35
----------------------
Backward compatibility warts
* "git name-rev --stdin" has been deprecated and issues a warning
when used; use "git name-rev --annotate-stdin" instead.
* "git clone --filter=... --recurse-submodules" only makes the
top-level a partial clone, while submodules are fully cloned. This
behaviour is changed to pass the same filter down to the submodules.
* With the fixes for CVE-2022-24765 that are common with versions of
Git 2.30.4, 2.31.3, 2.32.2, 2.33.3, 2.34.3, and 2.35.3, Git has
been taught not to recognise repositories owned by other users, in
order to avoid getting affected by their config files and hooks.
You can list the path to the safe/trusted repositories that may be
owned by others on a multi-valued configuration variable
`safe.directory` to override this behaviour, or use '*' to declare
that you trust anything.
Note to those who build from the source
* Since Git 2.31, our source assumed that the compiler you use to
build Git supports variadic macros, with an easy-to-use escape
hatch to allow compilation without variadic macros with an request
to report that you had to use the escape hatch to the list.
Because we haven't heard from anybody who actually needed to use
the escape hatch, it has been removed, making support of variadic
macros a hard requirement.
UI, Workflows & Features
* Assorted updates to "git cat-file", especially "-h".
* The command line completion (in contrib/) learns to complete
arguments to give to "git sparse-checkout" command.
* "git log --remerge-diff" shows the difference from mechanical merge
result and the result that is actually recorded in a merge commit.
* "git log" and friends learned an option --exclude-first-parent-only
to propagate UNINTERESTING bit down only along the first-parent
chain, just like --first-parent option shows commits that lack the
UNINTERESTING bit only along the first-parent chain.
* The command line completion script (in contrib/) learned to
complete all Git subcommands, including the ones that are normally
hidden, when GIT_COMPLETION_SHOW_ALL_COMMANDS is used.
* "git branch" learned the "--recurse-submodules" option.
* A user can forget to make a script file executable before giving
it to "git bisect run". In such a case, all tests will exit with
126 or 127 error codes, even on revisions that are marked as good.
Try to recognize this situation and stop iteration early.
* When "index-pack" dies due to incoming data exceeding the maximum
allowed input size, include the value of the limit in the error
message.
* The error message given by "git switch HEAD~4" has been clarified
to suggest the "--detach" option that is required.
* In sparse-checkouts, files mis-marked as missing from the working tree
could lead to later problems. Such files were hard to discover, and
harder to correct. Automatically detecting and correcting the marking
of such files has been added to avoid these problems.
* "git cat-file" learns "--batch-command" mode, which is a more
flexible interface than the existing "--batch" or "--batch-check"
modes, to allow different kinds of inquiries made.
* The level of verbose output from the ort backend during inner merge
has been aligned to that of the recursive backend.
* "git remote rename A B", depending on the number of remote-tracking
refs involved, takes long time renaming them. The command has been
taught to show progress bar while making the user wait.
* Bundle file format gets extended to allow a partial bundle,
filtered by similar criteria you would give when making a
partial/lazy clone.
* A new built-in userdiff driver for kotlin has been added.
* "git repack" learned a new configuration to disable triggering of
age-old "update-server-info" command, which is rarely useful these
days.
* "git stash" does not allow subcommands it internally runs as its
implementation detail, except for "git reset", to emit messages;
now "git reset" part has also been squelched.
* "git ls-tree" learns "--oid-only" option, similar to "--name-only",
and more generalized "--format" option.
* "git fetch --refetch" learned to fetch everything without telling
the other side what we already have, which is useful when you
cannot trust what you have in the local object store.
* "git branch" gives hint when branch tracking cannot be established
because fetch refspecs from multiple remote repositories overlap.
* "git worktree list --porcelain" did not c-quote pathnames and lock
reasons with unsafe bytes correctly, which is worked around by
introducing NUL terminated output format with "-z".
Performance, Internal Implementation, Development Support etc.
* "git apply" (ab)used the util pointer of the string-list to keep
track of how each symbolic link needs to be handled, which has been
simplified by using strset.
* Fix a hand-rolled alloca() imitation that may have violated
alignment requirement of data being sorted in compatibility
implementation of qsort_s() and stable qsort().
* Use the parse-options API in "git reflog" command.
* The conditional inclusion mechanism of configuration files using
"[includeIf <condition>]" learns to base its decision on the
URL of the remote repository the repository interacts with.
(merge 399b198489 jt/conditional-config-on-remote-url later to maint).
* "git name-rev --stdin" does not behave like usual "--stdin" at
all. Start the process of renaming it to "--annotate-stdin".
(merge a2585719b3 jc/name-rev-stdin later to maint).
* "git update-index", "git checkout-index", and "git clean" are
taught to work better with the sparse checkout feature.
* Use an internal call to reset_head() helper function instead of
spawning "git checkout" in "rebase", and update code paths that are
involved in the change.
* Messages "ort" merge backend prepares while dealing with conflicted
paths were unnecessarily confusing since it did not differentiate
inner merges and outer merges.
* Small modernization of the rerere-train script (in contrib/).
* Use designated initializers we started using in mid 2017 in more
parts of the codebase that are relatively quiescent.
* Improve failure case behaviour of xdiff library when memory
allocation fails.
* General clean-up in reftable implementation, including
clarification of the API documentation, tightening the code to
honor documented length limit, etc.
* Remove the escape hatch we added when we introduced the weather
balloon to use variadic macros unconditionally, to make it official
that we now have a hard dependency on the feature.
* Makefile refactoring with a bit of suffixes rule stripping to
optimize the runtime overhead.
* "git stash drop" is reimplemented as an internal call to
reflog_delete() function, instead of invoking "git reflog delete"
via run_command() API.
* Count string_list items in size_t, not "unsigned int".
* The single-key interactive operation used by "git add -p" has been
made more robust.
* Remove unneeded <meta http-equiv=content-type...> from gitweb
output.
* "git name-rev" learned to use the generation numbers when setting
the lower bound of searching commits used to explain the revision,
when available, instead of committer time.
* Replace core.fsyncObjectFiles with two new configuration variables,
core.fsync and core.fsyncMethod.
* Updates to refs traditionally weren't fsync'ed, but we can
configure using core.fsync variable to do so.
* "git reflog" command now uses parse-options API to parse its
command line options.
Fixes since v2.35
-----------------
* "rebase" and "stash" in secondary worktrees are broken in
Git 2.35.0, which has been corrected.
* "git pull --rebase" ignored the rebase.autostash configuration
variable when the remote history is a descendant of our history,
which has been corrected.
(merge 3013d98d7a pb/pull-rebase-autostash-fix later to maint).
* "git update-index --refresh" has been taught to deal better with
racy timestamps (just like "git status" already does).
(merge 2ede073fd2 ms/update-index-racy later to maint).
* Avoid tests that are run under GIT_TRACE2 set from failing
unnecessarily.
(merge 944d808e42 js/test-unset-trace2-parents later to maint).
* The merge-ort misbehaved when merge.renameLimit configuration is
set too low and failed to find all renames.
(merge 9ae39fef7f en/merge-ort-restart-optim-fix later to maint).
* We explain that revs come first before the pathspec among command
line arguments, but did not spell out that dashed options come
before other args, which has been corrected.
(merge c11f95010c tl/doc-cli-options-first later to maint).
* "git add -p" rewritten in C regressed hunk splitting in some cases,
which has been corrected.
(merge 7008ddc645 pw/add-p-hunk-split-fix later to maint).
* "git fetch --negotiate-only" is an internal command used by "git
push" to figure out which part of our history is missing from the
other side. It should never recurse into submodules even when
fetch.recursesubmodules configuration variable is set, nor it
should trigger "gc". The code has been tightened up to ensure it
only does common ancestry discovery and nothing else.
(merge de4eaae63a gc/fetch-negotiate-only-early-return later to maint).
* The code path that verifies signatures made with ssh were made to
work better on a system with CRLF line endings.
(merge caeef01ea7 fs/ssh-signing-crlf later to maint).
* "git sparse-checkout init" failed to write into $GIT_DIR/info
directory when the repository was created without one, which has
been corrected to auto-create it.
(merge 7f44842ac1 jt/sparse-checkout-leading-dir-fix later to maint).
* Cloning from a repository that does not yet have any branches or
tags but has other refs resulted in a "remote transport reported
error", which has been corrected.
(merge dccea605b6 jt/clone-not-quite-empty later to maint).
* Mark in various places in the code that the sparse index and the
split index features are mutually incompatible.
(merge 451b66c533 js/sparse-vs-split-index later to maint).
* Update the logic to compute alignment requirement for our mem-pool.
(merge e38bcc66d8 jc/mem-pool-alignment later to maint).
* Pick a better random number generator and use it when we prepare
temporary filenames.
(merge 47efda967c bc/csprng-mktemps later to maint).
* Update the contributor-facing documents on proposed log messages.
(merge cdba0295b0 jc/doc-log-messages later to maint).
* When "git fetch --prune" failed to prune the refs it wanted to
prune, the command issued error messages but exited with exit
status 0, which has been corrected.
(merge c9e04d905e tg/fetch-prune-exit-code-fix later to maint).
* Problems identified by Coverity in the reftable code have been
corrected.
(merge 01033de49f hn/reftable-coverity-fixes later to maint).
* A bug that made multi-pack bitmap and the object order out-of-sync,
making the .midx data corrupt, has been fixed.
(merge f8b60cf99b tb/midx-bitmap-corruption-fix later to maint).
* The build procedure has been taught to notice older version of zlib
and enable our replacement uncompress2() automatically.
(merge 07564773c2 ab/auto-detect-zlib-compress2 later to maint).
* Interaction between fetch.negotiationAlgorithm and
feature.experimental configuration variables has been corrected.
(merge 714edc620c en/fetch-negotiation-default-fix later to maint).
* "git diff --diff-filter=aR" is now parsed correctly.
(merge 75408ca949 js/diff-filter-negation-fix later to maint).
* When "git subtree" wants to create a merge, it used "git merge" and
let it be affected by end-user's "merge.ff" configuration, which
has been corrected.
(merge 9158a3564a tk/subtree-merge-not-ff-only later to maint).
* Unlike "git apply", "git patch-id" did not handle patches with
hunks that has only 1 line in either preimage or postimage, which
has been corrected.
(merge 757e75c81e jz/patch-id-hunk-header-parsing-fix later to maint).
* "receive-pack" checks if it will do any ref updates (various
conditions could reject a push) before received objects are taken
out of the temporary directory used for quarantine purposes, so
that a push that is known-to-fail will not leave crufts that a
future "gc" needs to clean up.
(merge 5407764069 cb/clear-quarantine-early-on-all-ref-update-errors later to maint).
* When there is no object to write .bitmap file for, "git
multi-pack-index" triggered an error, instead of just skipping,
which has been corrected.
(merge eb57277ba3 tb/midx-no-bitmap-for-no-objects later to maint).
* "git cmd -h" outside a repository should error out cleanly for many
commands, but instead it hit a BUG(), which has been corrected.
(merge 87ad07d735 js/short-help-outside-repo-fix later to maint).
* "working tree" and "per-worktree ref" were in glossary, but
"worktree" itself wasn't, which has been corrected.
(merge 2df5387ed0 jc/glossary-worktree later to maint).
* L10n support for a few error messages.
(merge 3d3c23b3a7 bs/forbid-i18n-of-protocol-token-in-fetch-pack later to maint).
* Test modernization.
(merge d4fe066e4b sy/t0001-use-path-is-helper later to maint).
* "git log --graph --graph" used to leak a graph structure, and there
was no way to countermand "--graph" that appear earlier on the
command line. A "--no-graph" option has been added and resource
leakage has been plugged.
* Error output given in response to an ambiguous object name has been
improved.
(merge 3a73c1dfaf ab/ambiguous-object-name later to maint).
* "git sparse-checkout" wants to work with per-worktree configuration,
but did not work well in a worktree attached to a bare repository.
(merge 3ce1138272 ds/sparse-checkout-requires-per-worktree-config later to maint).
* Setting core.untrackedCache to true failed to add the untracked
cache extension to the index.
* Workaround we have for versions of PCRE2 before their version 10.36
were in effect only for their versions newer than 10.36 by mistake,
which has been corrected.
(merge 97169fc361 rs/pcre-invalid-utf8-fix-fix later to maint).
* Document Taylor as a new member of Git PLC at SFC. Welcome.
(merge e8d56ca863 tb/coc-plc-update later to maint).
* "git checkout -b branch/with/multi/level/name && git stash" only
recorded the last level component of the branch name, which has
been corrected.
* Check the return value from parse_tree_indirect() to turn segfaults
into calls to die().
(merge 8d2eaf649a gc/parse-tree-indirect-errors later to maint).
* Newer version of GPGSM changed its output in a backward
incompatible way to break our code that parses its output. It also
added more processes our tests need to kill when cleaning up.
Adjustments have been made to accommodate these changes.
(merge b0b70d54c4 fs/gpgsm-update later to maint).
* The untracked cache newly computed weren't written back to the
on-disk index file when there is no other change to the index,
which has been corrected.
* "git config -h" did not describe the "--type" option correctly.
(merge 5445124fad mf/fix-type-in-config-h later to maint).
* The way generation number v2 in the commit-graph files are
(not) handled has been corrected.
(merge 6dbf4b8172 ds/commit-graph-gen-v2-fixes later to maint).
* The method to trigger malloc check used in our tests no longer work
with newer versions of glibc.
(merge baedc59543 ep/test-malloc-check-with-glibc-2.34 later to maint).
* When "git fetch --recurse-submodules" grabbed submodule commits
that would be needed to recursively check out newly fetched commits
in the superproject, it only paid attention to submodules that are
in the current checkout of the superproject. We now do so for all
submodules that have been run "git submodule init" on.
* "git rebase $base $non_branch_commit", when $base is an ancestor or
the $non_branch_commit, modified the current branch, which has been
corrected.
* When "shallow" information is updated, we forgot to update the
in-core equivalent, which has been corrected.
* When creating a loose object file, we didn't report the exact
filename of the file we failed to fsync, even though the
information was readily available, which has been corrected.
* "git am" can read from the standard input when no mailbox is given
on the command line, but the end-user gets no indication when it
happens, making Git appear stuck.
(merge 7b20af6a06 jc/mailsplit-warn-on-tty later to maint).
* "git mv" failed to refresh the cached stat information for the
entry it moved.
(merge b7f9130a06 vd/mv-refresh-stat later to maint).

Git 2.33.1 Release Notes
========================
This primarily is to backport various fixes accumulated during the
development towards Git 2.34, the next feature release.
Fixes since v2.33
-----------------
* The unicode character width table (used for output alignment) has
been updated.
* Input validation of "git pack-objects --stdin-packs" has been
corrected.
* Bugfix for common ancestor negotiation recently introduced in "git
push" codepath.
* "git pull" had various corner cases that were not well thought out
around its --rebase backend, e.g. "git pull --ff-only" did not stop
but went ahead and rebased when the history on other side is not a
descendant of our history. The series tries to fix them up.
* "git apply" miscounted the bytes and failed to read to the end of
binary hunks.
* "git range-diff" code clean-up.
* "git commit --fixup" now works with "--edit" again, after it was
broken in v2.32.
* Use upload-artifacts v1 (instead of v2) for 32-bit linux, as the
new version has a blocker bug for that architecture.
* Checking out all the paths from HEAD during the last conflicted
step in "git rebase" and continuing would cause the step to be
skipped (which is expected), but leaves MERGE_MSG file behind in
$GIT_DIR and confuses the next "git commit", which has been
corrected.
* Various bugs in "git rebase -r" have been fixed.
* mmap() imitation used to call xmalloc() that dies upon malloc()
failure, which has been corrected to just return an error to the
caller to be handled.
* "git diff --relative" segfaulted and/or produced incorrect result
when there are unmerged paths.
* The delayed checkout code path in "git checkout" etc. were chatty
even when --quiet and/or --no-progress options were given.
* "git branch -D <branch>" used to refuse to remove a broken branch
ref that points at a missing commit, which has been corrected.
* Build update for Apple clang.
* The parser for the "--nl" option of "git column" has been
corrected.
* "git upload-pack" which runs on the other side of "git fetch"
forgot to take the ref namespaces into account when handling
want-ref requests.
* The sparse-index support can corrupt the index structure by storing
a stale and/or uninitialized data, which has been corrected.
* Buggy tests could damage repositories outside the throw-away test
area we created. We now by default export GIT_CEILING_DIRECTORIES
to limit the damage from such a stray test.
* Even when running "git send-email" without its own threaded
discussion support, a threading related header in one message is
carried over to the subsequent message to result in an unwanted
threading, which has been corrected.
* The output from "git fast-export", when its anonymization feature
is in use, showed an annotated tag incorrectly.
* Recent "diff -m" changes broke "gitk", which has been corrected.
* "git maintenance" scheduler fix for macOS.
* A pathname in an advice message has been made cut-and-paste ready.
* The "git apply -3" code path learned not to bother the lower level
merge machinery when the three-way merge can be trivially resolved
without the content level merge.
* The code that optionally creates the *.rev reverse index file has
been optimized to avoid needless computation when it is not writing
the file out.
* "git range-diff -I... <range> <range>" segfaulted, which has been
corrected.
* The order in which various files that make up a single (conceptual)
packfile has been reevaluated and straightened up. This matters in
correctness, as an incomplete set of files must not be shown to a
running Git.
* The "mode" word is useless in a call to open(2) that does not
create a new file. Such a call in the files backend of the ref
subsystem has been cleaned up.
* "git update-ref --stdin" failed to flush its output as needed,
which potentially led the conversation to a deadlock.
* When "git am --abort" fails to abort correctly, it still exited
with exit status of 0, which has been corrected.
* Correct nr and alloc members of strvec struct to be of type size_t.
* "git stash", where the tentative change involves changing a
directory to a file (or vice versa), was confused, which has been
corrected.
* "git clone" from a repository whose HEAD is unborn into a bare
repository didn't follow the branch name the other side used, which
is corrected.
* "git cvsserver" had a long-standing bug in its authentication code,
which has finally been corrected (it is unclear and is a separate
question if anybody is seriously using it, though).
* "git difftool --dir-diff" mishandled symbolic links.
* Sensitive data in the HTTP trace were supposed to be redacted, but
we failed to do so in HTTP/2 requests.
* "make clean" has been updated to remove leftover .depend/
directories, even when it is not told to use them to compute header
dependencies.
* Protocol v0 clients can get stuck parsing a malformed feature line.
Also contains various documentation updates and code clean-ups.
|
|
Git 2.31.1 Release Notes
========================
Fixes since v2.31
-----------------
* The fsmonitor interface read from its input without making sure
there is something to read from. This bug is new in 2.31
timeframe.
* The data structure used by fsmonitor interface was not properly
duplicated during an in-core merge, leading to use-after-free etc.
* "git bisect" reimplemented more in C during 2.30 timeframe did not
take an annotated tag as a good/bad endpoint well. This regression
has been corrected.
* Fix macros that can silently inject unintended null-statements.
* CALLOC_ARRAY() macro replaces many uses of xcalloc().
* Update insn in Makefile comments to run fuzz-all target.
* Fix a corner case bug in "git mv" on case insensitive systems,
which was introduced in 2.29 timeframe.
Also contains various documentation updates and code clean-ups.
Git 2.31 Release Notes
======================
Updates since v2.30
-------------------
Backward incompatible and other important changes
* The "pack-redundant" command, which has been left stale with almost
unusable performance issues, now warns loudly when it gets used, as
we no longer want to recommend its use (instead just "repack -d"
instead).
* The development community has adopted Contributor Covenant v2.0 to
update from v1.4 that we have been using.
* The support for deprecated PCRE1 library has been dropped.
* Fixes for CVE-2021-21300 in Git 2.30.2 (and earlier) is included.
UI, Workflows & Features
* The "--format=%(trailers)" mechanism gets enhanced to make it
easier to design output for machine consumption.
* When a user does not tell "git pull" to use rebase or merge, the
command gives a loud message telling a user to choose between
rebase or merge but creates a merge anyway, forcing users who would
want to rebase to redo the operation. Fix an early part of this
problem by tightening the condition to give the message---there is
no reason to stop or force the user to choose between rebase or
merge if the history fast-forwards.
* The configuration variable 'core.abbrev' can be set to 'no' to
force no abbreviation regardless of the hash algorithm.
* "git rev-parse" can be explicitly told to give output as absolute
or relative path with the `--path-format=(absolute|relative)` option.
* Bash completion (in contrib/) update to make it easier for
end-users to add completion for their custom "git" subcommands.
* "git maintenance" learned to drive scheduled maintenance on
platforms whose native scheduling methods are not 'cron'.
* After expiring a reflog and making a single commit, the reflog for
the branch would record a single entry that knows both @{0} and
@{1}, but we failed to answer "what commit were we on?", i.e. @{1}
* "git bundle" learns "--stdin" option to read its refs from the
standard input. Also, it now does not lose refs whey they point
at the same object.
* "git log" learned a new "--diff-merges=<how>" option.
* "git ls-files" can and does show multiple entries when the index is
unmerged, which is a source for confusion unless -s/-u option is in
use. A new option --deduplicate has been introduced.
* `git worktree list` now annotates worktrees as prunable, shows
locked and prunable attributes in --porcelain mode, and gained
a --verbose option.
* "git clone" tries to locally check out the branch pointed at by
HEAD of the remote repository after it is done, but the protocol
did not convey the information necessary to do so when copying an
empty repository. The protocol v2 learned how to do so.
* There are other ways than ".." for a single token to denote a
"commit range", namely "<rev>^!" and "<rev>^-<n>", but "git
range-diff" did not understand them.
* The "git range-diff" command learned "--(left|right)-only" option
to show only one side of the compared range.
* "git mergetool" feeds three versions (base, local and remote) of
a conflicted path unmodified. The command learned to optionally
prepare these files with unconflicted parts already resolved.
* The .mailmap is documented to be read only from the root level of a
working tree, but a stray file in a bare repository also was read
by accident, which has been corrected.
* "git maintenance" tool learned a new "pack-refs" maintenance task.
* The error message given when a configuration variable that is
expected to have a boolean value has been improved.
* Signed commits and tags now allow verification of objects, whose
two object names (one in SHA-1, the other in SHA-256) are both
signed.
* "git rev-list" command learned "--disk-usage" option.
* "git {diff,log} --{skip,rotate}-to=<path>" allows the user to
discard diff output for early paths or move them to the end of the
output.
* "git difftool" learned "--skip-to=<path>" option to restart an
interrupted session from an arbitrary path.
* "git grep" has been tweaked to be limited to the sparse checkout
paths.
* "git rebase --[no-]fork-point" gained a configuration variable
rebase.forkPoint so that users do not have to keep specifying a
non-default setting.
Performance, Internal Implementation, Development Support etc.
* A 3-year old test that was not testing anything useful has been
corrected.
* Retire more names with "sha1" in it.
* The topological walk codepath is covered by new trace2 stats.
* Update the Code-of-conduct to version 2.0 from the upstream (we've
been using version 1.4).
* "git mktag" validates its input using its own rules before writing
a tag object---it has been updated to share the logic with "git
fsck".
* Two new ways to feed configuration variable-value pairs via
environment variables have been introduced, and the way
GIT_CONFIG_PARAMETERS encodes variable/value pairs has been tweaked
to make it more robust.
* Tests have been updated so that they do not to get affected by the
name of the default branch "git init" creates.
* "git fetch" learns to treat ref updates atomically in all-or-none
fashion, just like "git push" does, with the new "--atomic" option.
* The peel_ref() API has been replaced with peel_iterated_oid().
* The .use_shell flag in struct child_process that is passed to
run_command() API has been clarified with a bit more documentation.
* Document, clean-up and optimize the code around the cache-tree
extension in the index.
* The ls-refs protocol operation has been optimized to narrow the
sub-hierarchy of refs/ it walks to produce response.
* When removing many branches and tags, the code used to do so one
ref at a time. There is another API it can use to delete multiple
refs, and it makes quite a lot of performance difference when the
refs are packed.
* The "pack-objects" command needs to iterate over all the tags when
automatic tag following is enabled, but it actually iterated over
all refs and then discarded everything outside "refs/tags/"
hierarchy, which was quite wasteful.
* A perf script was made more portable.
* Our setting of GitHub CI test jobs were a bit too eager to give up
once there is even one failure found. Tweak the knob to allow
other jobs keep running even when we see a failure, so that we can
find more failures in a single run.
* We've carried compatibility codepaths for compilers without
variadic macros for quite some time, but the world may be ready for
them to be removed. Force compilation failure on exotic platforms
where variadic macros are not available to find out who screams in
such a way that we can easily revert if it turns out that the world
is not yet ready.
* Code clean-up to ensure our use of hashtables using object names as
keys use the "struct object_id" objects, not the raw hash values.
* Lose the debugging aid that may have been useful in the past, but
no longer is, in the "grep" codepaths.
* Some pretty-format specifiers do not need the data in commit object
(e.g. "%H"), but we were over-eager to load and parse it, which has
been made even lazier.
* Get rid of "GETTEXT_POISON" support altogether, which may or may
not be controversial.
* Introduce an on-disk file to record revindex for packdata, which
traditionally was always created on the fly and only in-core.
* The commit-graph learned to use corrected commit dates instead of
the generation number to help topological revision traversal.
* Piecemeal of rewrite of "git bisect" in C continues.
* When a pager spawned by us exited, the trace log did not record its
exit status correctly, which has been corrected.
* Removal of GIT_TEST_GETTEXT_POISON continues.
* The code to implement "git merge-base --independent" was poorly
done and was kept from the very beginning of the feature.
* Preliminary changes to fsmonitor integration.
* Performance improvements for rename detection.
* The common code to deal with "chunked file format" that is shared
by the multi-pack-index and commit-graph files have been factored
out, to help codepaths for both filetypes to become more robust.
* The approach to "fsck" the incoming objects in "index-pack" is
attractive for performance reasons (we have them already in core,
inflated and ready to be inspected), but fundamentally cannot be
applied fully when we receive more than one pack stream, as a tree
object in one pack may refer to a blob object in another pack as
".gitmodules", when we want to inspect blobs that are used as
".gitmodules" file, for example. Teach "index-pack" to emit
objects that must be inspected later and check them in the calling
"fetch-pack" process.
* The logic to handle "trailer" related placeholders in the
"--format=" mechanisms in the "log" family and "for-each-ref"
family is getting unified.
* Raise the buffer size used when writing the index file out from
(obviously too small) 8kB to (clearly sufficiently large) 128kB.
* It is reported that open() on some platforms (e.g. macOS Big Sur)
can return EINTR even though our timers are set up with SA_RESTART.
A workaround has been implemented and enabled for macOS to rerun
open() transparently from the caller when this happens.
Fixes since v2.30
-----------------
* Diagnose command line error of "git rebase" early.
* Clean up option descriptions in "git cmd --help".
* "git stash" did not work well in a sparsely checked out working
tree.
* Some tests expect that "ls -l" output has either '-' or 'x' for
group executable bit, but setgid bit can be inherited from parent
directory and make these fields 'S' or 's' instead, causing test
failures.
* "git for-each-repo --config=<var> <cmd>" should not run <cmd> for
any repository when the configuration variable <var> is not defined
even once.
* Fix 2.29 regression where "git mergetool --tool-help" fails to list
all the available tools.
* Fix for procedure to building CI test environment for mac.
* The implementation of "git branch --sort" wrt the detached HEAD
display has always been hacky, which has been cleaned up.
* Newline characters in the host and path part of git:// URL are
now forbidden.
* "git diff" showed a submodule working tree with untracked cruft as
"Submodule commit <objectname>-dirty", but a natural expectation is
that the "-dirty" indicator would align with "git describe --dirty",
which does not consider having untracked files in the working tree
as source of dirtiness. The inconsistency has been fixed.
* When more than one commit with the same patch ID appears on one
side, "git log --cherry-pick A...B" did not exclude them all when a
commit with the same patch ID appears on the other side. Now it
does.
* Documentation for "git fsck" lost stale bits that has become
incorrect.
* Doc fix for packfile URI feature.
* When "git rebase -i" processes "fixup" insn, there is no reason to
clean up the commit log message, but we did the usual stripspace
processing. This has been corrected.
(merge f7d42ceec5 js/rebase-i-commit-cleanup-fix later to maint).
* Fix in passing custom args from "git clone" to "upload-pack" on the
other side.
(merge ad6b5fefbd jv/upload-pack-filter-spec-quotefix later to maint).
* The command line completion (in contrib/) completed "git branch -d"
with branch names, but "git branch -D" offered tagnames in addition,
which has been corrected. "git branch -M" had the same problem.
(merge 27dc071b9a jk/complete-branch-force-delete later to maint).
* When commands are started from a subdirectory, they may have to
compare the path to the subdirectory (called prefix and found out
from $(pwd)) with the tracked paths. On macOS, $(pwd) and
readdir() yield decomposed path, while the tracked paths are
usually normalized to the precomposed form, causing mismatch. This
has been fixed by taking the same approach used to normalize the
command line arguments.
(merge 5c327502db tb/precompose-prefix-too later to maint).
* Even though invocations of "die()" were logged to the trace2
system, "BUG()"s were not, which has been corrected.
(merge 0a9dde4a04 jt/trace2-BUG later to maint).
* "git grep --untracked" is meant to be "let's ALSO find in these
files on the filesystem" when looking for matches in the working
tree files, and does not make any sense if the primary search is
done against the index, or the tree objects. The "--cached" and
"--untracked" options have been marked as mutually incompatible.
(merge 0c5d83b248 mt/grep-cached-untracked later to maint).
* Fix "git fsck --name-objects" which apparently has not been used by
anybody who is motivated enough to report breakage.
(merge e89f89361c js/fsck-name-objects-fix later to maint).
* Avoid individual tests in t5411 from getting affected by each other
by forcing them to use separate output files during the test.
(merge 822ee894f6 jx/t5411-unique-filenames later to maint).
* Test to make sure "git rev-parse one-thing one-thing" gives
the same thing twice (when one-thing is --since=X).
(merge a5cdca4520 ew/rev-parse-since-test later to maint).
* When certain features (e.g. grafts) used in the repository are
incompatible with the use of the commit-graph, we used to silently
turned commit-graph off; we now tell the user what we are doing.
(merge c85eec7fc3 js/commit-graph-warning later to maint).
* Objects that lost references can be pruned away, even when they
have notes attached to it (and these notes will become dangling,
which in turn can be pruned with "git notes prune"). This has been
clarified in the documentation.
(merge fa9ab027ba mz/doc-notes-are-not-anchors later to maint).
* The error codepath around the "--temp/--prefix" feature of "git
checkout-index" has been improved.
(merge 3f7ba60350 mt/checkout-index-corner-cases later to maint).
* The "git maintenance register" command had trouble registering bare
repositories, which had been corrected.
* A handful of multi-word configuration variable names in
documentation that are spelled in all lowercase have been corrected
to use the more canonical camelCase.
(merge 7dd0eaa39c dl/doc-config-camelcase later to maint).
* "git push $there --delete ''" should have been diagnosed as an
error, but instead turned into a matching push, which has been
corrected.
(merge 20e416409f jc/push-delete-nothing later to maint).
* Test script modernization.
(merge 488acf15df sv/t7001-modernize later to maint).
* An under-allocation for the untracked cache data has been corrected.
(merge 6347d649bc jh/untracked-cache-fix later to maint).
* Other code cleanup, docfix, build fix, etc.
(merge e3f5da7e60 sg/t7800-difftool-robustify later to maint).
(merge 9d336655ba js/doc-proto-v2-response-end later to maint).
(merge 1b5b8cf072 jc/maint-column-doc-typofix later to maint).
(merge 3a837b58e3 cw/pack-config-doc later to maint).

Git 2.30 Release Notes
======================
Updates since v2.29
-------------------
UI, Workflows & Features
* Userdiff for PHP update.
* Userdiff for Rust update.
* Userdiff for CSS update.
* The command line completion script (in contrib/) learned that "git
stash show" takes the options "git diff" takes.
* "git worktree list" now shows if each worktree is locked. This
possibly may open us to show other kinds of states in the future.
* "git maintenance", an extended big brother of "git gc", continues
to evolve.
* "git push --force-with-lease[=<ref>]" can easily be misused to lose
commits unless the user takes good care of their own "git fetch".
A new option "--force-if-includes" attempts to ensure that what is
being force-pushed was created after examining the commit at the
tip of the remote ref that is about to be force-replaced.
* "git clone" learned clone.defaultremotename configuration variable
to customize what nickname to use to call the remote the repository
was cloned from.
* "git checkout" learned to use checkout.guess configuration variable
and enable/disable its "--[no-]guess" option accordingly.
* "git resurrect" script (in contrib/) learned that the object names
may be longer than 40-hex depending on the hash function in use.
* "git diff A...B" learned "git diff --merge-base A B", which is a
longer short-hand to say the same thing.
* A sample 'push-to-checkout' hook, that performs the same as
what the built-in default action does, has been added.
* "git diff" family of commands learned the "-I<regex>" option to
ignore hunks whose changed lines all match the given pattern.
* The userdiff pattern learned to identify the function definition in
POSIX shells and bash.
* "git checkout-index" did not consistently signal an error with its
exit status, but now it does.
* A commit and tag object may have CR at the end of each and
every line (you can create such an object with hash-object or
using --cleanup=verbatim to decline the default clean-up
action), but it would make it impossible to have a blank line
to separate the title from the body of the message. We are now
more lenient and accept a line with lone CR on it as a blank line,
too.
* Exit codes from "git remote add" etc. were not usable by scripted
callers, but now they are.
* "git archive" now allows compression level higher than "-9"
when generating tar.gz output.
* Zsh autocompletion (in contrib/) update.
* The maximum length of output filenames "git format-patch" creates
has become configurable (used to be capped at 64).
* "git rev-parse" learned the "--end-of-options" to help scripts to
safely take a parameter that is supposed to be a revision, e.g.
"git rev-parse --verify -q --end-of-options $rev".
* The command line completion script (in contrib/) learned to expand
commands that are alias of alias.
* "git update-ref --stdin" learns to take multiple transactions in a
single session.
* Various subcommands of "git config" that take value_regex
learned the "--literal-value" option to take the value_regex option
as a literal string.
* The transport layer was taught to optionally exchange the session
ID assigned by the trace2 subsystem during fetch/push transactions.
* "git imap-send" used to ignore configuration variables like
core.askpass; this has been corrected.
* "git $cmd $args", when $cmd is not a recognised subcommand, by
default tries to see if $cmd is a typo of an existing subcommand
and optionally executes the corrected command if there is only one
possibility, depending on the setting of help.autocorrect; the
users can now disable the whole thing, including the cycles spent
to find a likely typo, by setting the configuration variable to
'never'.
* "@" sometimes worked (e.g. "git push origin @:there") as a part of
a refspec element, but "git push origin @" did not work, which has
been corrected.
Performance, Internal Implementation, Development Support etc.
* Use "git archive" more to produce the release tarball.
* GitHub Actions automated test improvement to skip tests on a tree
identical to what has already been tested.
* Test-coverage for running commit-graph task "git maintenance" has
been extended.
* Our test scripts can be told to run only individual pieces while
skipping others with the "--run=..." option; they were taught to
take a substring of test title, in addition to numbers, to name the
test pieces to run.
* Adjust tests so that they won't scream when the default initial
branch name is different from 'master'.
* Rewriting "git bisect" in C continues.
* More preliminary tests have been added to document desired outcomes
of various "directory rename" situations.
* Micro clean-up of a couple of test scripts.
* "git diff" and other commands that share the same machinery to
compare with working tree files have been taught to take advantage
of the fsmonitor data when available.
* The code to detect premature EOF in the sideband demultiplexer has
been cleaned up.
* "git fetch --depth=<n>" over the stateless RPC / smart HTTP
transport handled EOF from the client poorly at the server end.
* A specialization of hashmap that uses a string as key has been
introduced. Hopefully it will see wider use over time.
* "git bisect start/next" in a large span of history spends a lot of
time trying to come up with exactly the half-way point; this can be
optimized by stopping when we see a commit that is close enough to
the half-way point.
* A lazily defined test prerequisite can now be defined in terms of
another lazily defined test prerequisite.
* Expectation for the original contributor after responding to a
review comment to use the explanation in a patch update has been
described.
* Multiple "credential-store" backends can race to lock the same
file, causing everybody else but one to fail---reattempt locking
with some timeout to reduce the rate of the failure.
* "git-parse-remote" shell script library outlived its usefulness.
* Like die() and error(), a call to warning() will also trigger a
trace2 event.
* Use of non-reentrant localtime() has been removed.
* Non-reentrant time-related library functions and ctime/asctime with
awkward calling interfaces are banned from the codebase.
Fixes since v2.29
-----------------
* In 2.29, "--committer-date-is-author-date" option of "rebase" and
"am" subcommands lost the e-mail address by mistake, which has been
corrected.
(merge 5f35edd9d7 jk/committer-date-is-author-date-fix later to maint).
* "git checkout -p A...B [-- <path>]" did not work, even though the
same command without "-p" correctly used the merge-base between
commits A and B.
(merge 35166b1fb5 dl/checkout-p-merge-base later to maint).
* The side-band status report can be sent at the same time as the
primary payload multiplexed, but the demultiplexer on the receiving
end incorrectly split a single status report into two, which has
been corrected.
(merge 712b0377db js/avoid-split-sideband-message later to maint).
* "git fast-import" wasted a lot of memory when many marks were in use.
(merge 3f018ec716 jk/fast-import-marks-alloc-fix later to maint).
* A test helper "test_cmp A B" was taught to diagnose missing files A
or B as a bug in test, but some tests legitimately wanted to notice
a failure to even create file B as an error, in addition to leaving
the expected result in it, and were misdiagnosed as a bug. This
has been corrected.
(merge 262d5ad5a5 es/test-cmp-typocatcher later to maint).
* When "git commit-graph" detects the same commit recorded more than
once while it is merging the layers, it used to die. The code now
ignores all but one of them and continues.
(merge 85102ac71b ds/commit-graph-merging-fix later to maint).
* The meaning of a Signed-off-by trailer can vary from project to
project; this and also what it means to this project has been
clarified in the documentation.
(merge 3abd4a67d9 bk/sob-dco later to maint).
* "git credential' didn't honor the core.askPass configuration
variable (among other things), which has been corrected.
(merge 567ad2c0f9 tk/credential-config later to maint).
* Dev support to catch a tentative definition of a variable in our C
code as an error.
(merge 5539183622 jk/no-common later to maint).
* "git rebase --rebase-merges" did not correctly pass --gpg-sign
command line option to underlying "git merge" when replaying a merge
using non-default merge strategy or when replaying an octopus merge
(because replaying a two-head merge with the default strategy was
done in a separate codepath, the problem did not trigger for most
users), which has been corrected.
(merge 43ad4f2eca sc/sequencer-gpg-octopus later to maint).
* "git apply -R" did not handle patches that touch the same path
twice correctly, which has been corrected. This is most relevant
in a patch that changes a path from a regular file to a symbolic
link (and vice versa).
(merge b0f266de11 jt/apply-reverse-twice later to maint).
* A recent oid->hash conversion missed one spot, breaking "git svn".
(merge 03bb366de4 bc/svn-hash-oid-fix later to maint).
* The documentation on the "--abbrev=<n>" option did not say the
output may be longer than "<n>" hexdigits, which has been
clarified.
(merge cda34e0d0c jc/abbrev-doc later to maint).
* "git p4" now honors init.defaultBranch configuration.
(merge 1b09d1917f js/p4-default-branch later to maint).
* Recently the format of an internal state file "rebase -i" uses has
been tightened up for consistency, which would hurt those who start
"rebase -i" with old git and then continue with new git. Loosen
the reader side a bit (which we may want to tighten again in a year
or so).
(merge c779386182 jc/sequencer-stopped-sha-simplify later to maint).
* The code to see if "git stash drop" can safely remove refs/stash
has been made more careful.
(merge 4f44c5659b rs/empty-reflog-check-fix later to maint).
* "git log -L<range>:<path>" is documented to take no pathspec, but
this was not enforced by the command line option parser, which has
been corrected.
(merge 39664cb0ac jc/line-log-takes-no-pathspec later to maint).
* "git format-patch --output=there" did not work as expected and
instead crashed. The option is now supported.
(merge dc1672dd10 jk/format-patch-output later to maint).
* Define ARM64 compiled with MSVC to be little-endian.
(merge 0c038fc65a dg/bswap-msvc later to maint).
* "git rebase -i" did not store ORIG_HEAD correctly.
(merge 8843302307 pw/rebase-i-orig-head later to maint).
* "git blame -L :funcname -- path" did not work well for a path for
which a userdiff driver is defined.
* "make DEVELOPER=1 sparse" used to run sparse and let it emit
warnings; now such warnings will cause an error.
(merge 521dc56270 jc/sparse-error-for-developer-build later to maint).
* "git blame --ignore-revs-file=<file>" learned to ignore a
non-existent object name in the input, instead of complaining.
(merge c714d05875 jc/blame-ignore-fix later to maint).
* Running "git diff" while allowing external diff in a state with
unmerged paths used to segfault, which has been corrected.
(merge d66851806f jk/diff-release-filespec-fix later to maint).
* Build configuration cleanup.
(merge b990f02fd8 ab/config-mak-uname-simplify later to maint).
* Fix regression introduced when nvimdiff support in mergetool was added.
(merge 12026f46e7 pd/mergetool-nvimdiff later to maint).
* The exchange between receive-pack and proc-receive hook did not
carefully check for errors.
* The code was not prepared to deal with pack .idx file that is
larger than 4GB.
(merge 81c4c5cf2e jk/4gb-idx later to maint).
* Since jgit does not yet work with SHA-256 repositories, mark the
tests that use it not to run unless we are testing with ShA-1
repositories.
(merge ea699b4adc sg/t5310-jgit-wants-sha1 later to maint).
* Config parser fix for "git notes".
(merge 45fef1599a na/notes-displayref-is-not-boolean later to maint).
* Move a definition of compatibility wrapper from cache.h to
git-compat-util.h
(merge a76b138daa hn/sleep-millisec-decl later to maint).
* Error message fix.
(merge eaf5341538 km/stash-error-message-fix later to maint).
* "git pull --rebase --recurse-submodules" checked for local changes
in a wrong range and failed to run correctly when it should.
(merge 5176f20ffe pb/pull-rebase-recurse-submodules later to maint).
* "git push" that is killed may leave a pack-objects process behind,
still computing to find a good compression, wasting cycles. This
has been corrected.
(merge 8b59935114 jk/stop-pack-objects-when-push-is-killed later to maint).
* "git fetch" that is killed may leave a pack-objects process behind,
still computing to find a good compression, wasting cycles. This
has been corrected.
(merge 309a4028e7 jk/stop-pack-objects-when-fetch-is-killed later to maint).
* "git add -i" failed to honor custom colors configured to show
patches, which has been corrected.
(merge 96386faa03 js/add-i-color-fix later to maint).
* Processes that access packdata while the .idx file gets removed
(e.g. while repacking) did not fail or fall back gracefully as they
could.
(merge 506ec2fbda tb/idx-midx-race-fix later to maint).
* "git apply" adjusted the permission bits of working-tree files and
directories according to core.sharedRepository setting by mistake and
for a long time, which has been corrected.
(merge eb3c027e17 mt/do-not-use-scld-in-working-tree later to maint).
* "fetch-pack" could pass NULL pointer to unlink(2) when it sees an
invalid filename; the error checking has been tightened to make
this impossible.
(merge 6031af387e rs/fetch-pack-invalid-lockfile later to maint).
* "git maintenance run/start/stop" needed to be run in a repository
to hold the lockfile they use, but didn't make sure they are
actually in a repository, which has been corrected.
* The glossary described a branch as an "active" line of development,
which is misleading---a stale and non-moving branch is still a
branch.
(merge eef1ceabd8 so/glossary-branch-is-not-necessarily-active later to maint).
* Newer versions of xsltproc can assign IDs in HTML documents it
generates in a consistent manner. Use the feature to help format
HTML version of the user manual reproducibly.
(merge 3569e11d69 ae/doc-reproducible-html later to maint).
* Tighten error checking in the codepath that responds to "git fetch".
(merge d43a21bdbb jk/check-config-parsing-error-in-upload-pack later to maint).
* "git pack-redundant" when there is only one packfile used to crash,
which has been corrected.
(merge 0696232390 jx/pack-redundant-on-single-pack later to maint).
* Other code cleanup, docfix, build fix, etc.

Git v2.29.2 Release Notes
=========================
This release is primarily to fix brown-paper-bag breakages in the
2.29.0 release.
Fixes since v2.29.1
-------------------
* In 2.29, "--committer-date-is-author-date" option of "rebase" and
"am" subcommands lost the e-mail address by mistake, which has been
corrected.
Git v2.29.1 Release Notes
=========================
This is to fix the build procedure change in 2.28 where we failed to
install a few programs that should be installed in /usr/bin (namely,
receive-pack, upload-archive and upload-pack) when the non-default
SKIP_DASHED_BUILT_INS installation option is in effect.
A minor glitch in a non-default installation may usually not deserve
a hotfix, but I know Git for Windows ship binaries built with this
option, so let's make an exception.
Git 2.29 Release Notes
======================
Updates since v2.28
-------------------
UI, Workflows & Features
* "git help log" has been enhanced by sharing more material from the
documentation for the underlying "git rev-list" command.
* "git for-each-ref --format=<>" learned %(contents:size).
* "git merge" learned to selectively omit " into <branch>" at the end
of the title of default merge message with merge.suppressDest
configuration.
* The component to respond to "git fetch" request is made more
configurable to selectively allow or reject object filtering
specification used for partial cloning.
* Stop when "sendmail.*" configuration variables are defined, which
could be a mistaken attempt to define "sendemail.*" variables.
* The existing backends for "git mergetool" based on variants of vim
have been refactored and then support for "nvim" has been added.
* "git bisect" learns the "--first-parent" option to find the first
breakage along the first-parent chain.
* "git log --first-parent -p" showed patches only for single-parent
commits on the first-parent chain; the "--first-parent" option has
been made to imply "-m". Use "--no-diff-merges" to restore the
previous behaviour to omit patches for merge commits.
* The commit labels used to explain each side of conflicted hunks
placed by the sequencer machinery have been made more readable by
humans.
* The "--batch-size" option of "git multi-pack-index repack" command
is now used to specify that very small packfiles are collected into
one until the total size roughly exceeds it.
* The recent addition of SHA-256 support is marked as experimental in
the documentation.
* "git fetch" learned --no-write-fetch-head option to avoid writing
the FETCH_HEAD file.
* Command line completion (in contrib/) usually omits redundant,
deprecated and/or dangerous options from its output; it learned to
optionally include all of them.
* The output from the "diff" family of the commands had abbreviated
object names of blobs involved in the patch, but its length was not
affected by the --abbrev option. Now it is.
* "git worktree" gained a "repair" subcommand to help users recover
after moving the worktrees or repository manually without telling
Git. Also, "git init --separate-git-dir" no longer corrupts
administrative data related to linked worktrees.
* The "--format=" option to the "for-each-ref" command and friends
learned a few more tricks, e.g. the ":short" suffix that applies to
"objectname" now also can be used for "parent", "tree", etc.
* "git worktree add" learns that the "-d" is a synonym to "--detach"
option to create a new worktree without being on a branch.
* "format-patch --range-diff=<prev> <origin>..HEAD" has been taught
not to ignore <origin> when <prev> is a single version.
* "add -p" now allows editing paths that were only added in intent.
* The 'meld' backend of the "git mergetool" learned to give the
underlying 'meld' the '--auto-merge' option, which would help
reduce the amount of text that requires manual merging.
* "git for-each-ref" and friends that list refs used to allow only
one --merged or --no-merged to filter them; they learned to take
combination of both kind of filtering.
* "git maintenance", a "git gc"'s big brother, has been introduced to
take care of more repository maintenance tasks, not limited to the
object database cleaning.
* "git receive-pack" that accepts requests by "git push" learned to
outsource most of the ref updates to the new "proc-receive" hook.
* "git push" that wants to be atomic and wants to send push
certificate learned not to prepare and sign the push certificate
when it fails the local check (hence due to atomicity it is known
that no certificate is needed).
* "git commit-graph write" learned to limit the number of bloom
filters that are computed from scratch with the --max-new-filters
option.
* The transport protocol v2 has become the default again.
* The installation procedure learned to optionally omit "git-foo"
executable files for each 'foo' built-in subcommand, which are only
required by old timers that still rely on the age old promise that
prepending "git --exec-path" output to PATH early in their script
will keep the "git-foo" calls they wrote working.
* The command line completion (in contrib/) learned that "git restore
-s <TAB>" is often followed by a refname.
* "git shortlog" has been taught to group commits by the contents of
the trailer lines, like "Reviewed-by:", "Coauthored-by:", etc.
* "git archive" learns the "--add-file" option to include untracked
files into a snapshot from a tree-ish.
* "git fetch" and "git push" support negative refspecs.
* "git format-patch" learns to take "whenAble" as a possible value
for the format.useAutoBase configuration variable to become no-op
when the automatically computed base does not make sense.
* Credential helpers are now allowed to terminate lines with CRLF
line ending, as well as LF line ending.
Performance, Internal Implementation, Development Support etc.
* The changed-path Bloom filter is improved using ideas from an
independent implementation.
* Updates to the changed-paths bloom filter.
* The test framework has been updated so that most tests will run
with predictable (artificial) timestamps.
* Preliminary clean-up of the refs API in preparation for adding a
new refs backend "reftable".
* Dev support to limit the use of test_must_fail to only git commands.
* While packing many objects in a repository with a promissor remote,
lazily fetching missing objects from the promissor remote one by
one may be inefficient---the code now attempts to fetch all the
missing objects in batch (obviously this won't work for a lazy
clone that lazily fetches tree objects as you cannot even enumerate
what blobs are missing until you learn which trees are missing).
* The pretend-object mechanism checks if the given object already
exists in the object store before deciding to keep the data
in-core, but the check would have triggered lazy fetching of such
an object from a promissor remote.
* The argv_array API is useful for not just managing argv but any
"vector" (NULL-terminated array) of strings, and has seen adoption
to a certain degree. It has been renamed to "strvec" to reduce the
barrier to adoption.
* The final leg of SHA-256 transition plus doc updates. Note that
there is no interoperability between SHA-1 and SHA-256
repositories yet.
* CMake support to build with MSVC for Windows bypassing the Makefile.
* A new helper function has_object() has been introduced to make it
easier to mark object existence checks that do and don't want to
trigger lazy fetches, and a few such checks are converted using it.
* A no-op replacement function implemented as a C preprocessor macro
does not perform as good a job as one implemented as a "static
inline" function in catching errors in parameters; replace the
former with the latter in <git-compat-util.h> header.
* Test framework update.
(merge d572f52a64 es/test-cmp-typocatcher later to maint).
* Updates to "git merge" tests, in preparation for a new merge
strategy backend.
* midx and commit-graph files now use the byte defined in their file
format specification for identifying the hash function used for
object names.
* The FETCH_HEAD is now always read from the filesystem regardless of
the ref backend in use, as its format is much richer than the
normal refs, and written directly by "git fetch" as a plain file..
* An unused binary has been discarded, and and a bunch of commands
have been turned into into built-in.
* A handful of places in in-tree code still relied on being able to
execute the git subcommands, especially built-ins, in "git-foo"
form, which have been corrected.
* When a packfile is removed by "git repack", multi-pack-index gets
cleared; the code was taught to do so less aggressively by first
checking if the midx actually refers to a pack that no longer
exists.
* Internal API clean-up to handle two options "diff-index" and "log"
have, which happen to share the same short form, more sensibly.
* The "add -i/-p" machinery has been written in C but it is not used
by default yet. It is made default to those who are participating
in feature.experimental experiment.
* Allow maintainers to tweak $(TAR) invocations done while making
distribution tarballs.
* "git index-pack" learned to resolve deltified objects with greater
parallelism.
* "diff-highlight" (in contrib/) had a logic to flush its output upon
seeing a blank line but the way it detected a blank line was broken.
* The logic to skip testing on the tagged commit and the tag itself
was not quite consistent which led to failure of Windows test
tasks. It has been revamped to consistently skip revisions that
have already been tested, based on the tree object of the revision.
Fixes since v2.28
-----------------
* The "mediawiki" remote backend which lives in contrib/mw-to-git/
and is not built with git by default, had an RCE bug allowing a
malicious MediaWiki server operator to inject arbitrary commands
for execution by a cloning client. This has been fixed.
The bug was discovered and reported by Joern Schneeweisz of GitLab
to the git-security mailing list. Its practical impact due to the
obscurity of git-remote-mediawiki was deemed small enough to forgo
a dedicated security release.
* "git clone --separate-git-dir=$elsewhere" used to stomp on the
contents of the existing directory $elsewhere, which has been
taught to fail when $elsewhere is not an empty directory.
(merge dfaa209a79 bw/fail-cloning-into-non-empty later to maint).
* With the base fix to 2.27 regresion, any new extensions in a v0
repository would still be silently honored, which is not quite
right. Instead, complain and die loudly.
(merge ec91ffca04 jk/reject-newer-extensions-in-v0 later to maint).
* Fetching from a lazily cloned repository resulted at the server
side in attempts to lazy fetch objects that the client side has,
many of which will not be available from the third-party anyway.
(merge 77aa0941ce jt/avoid-lazy-fetching-upon-have-check later to maint).
* Fix to an ancient bug caused by an over-eager attempt for
optimization.
(merge a98f7fb366 rs/add-index-entry-optim-fix later to maint).
* Pushing a ref whose name contains non-ASCII character with the
"--force-with-lease" option did not work over smart HTTP protocol,
which has been corrected.
(merge cd85b447bf bc/push-cas-cquoted-refname later to maint).
* "git mv src dst", when src is an unmerged path, errored out
correctly but with an incorrect error message to claim that src is
not tracked, which has been clarified.
(merge 9b906af657 ct/mv-unmerged-path-error later to maint).
* Fix to a regression introduced during 2.27 cycle.
(merge cada7308ad en/fill-directory-exponential later to maint).
* Command line completion (in contrib/) update.
(merge 688b87c81b mp/complete-show-color-moved later to maint).
* All "mergy" operations that internally use the merge-recursive
machinery should honor the merge.renormalize configuration, but
many of them didn't.
* Doc cleanup around "worktree".
(merge dc9c144be5 es/worktree-doc-cleanups later to maint).
* The "git blame --first-parent" option was not documented, but now
it is.
(merge 11bc12ae1e rp/blame-first-parent-doc later to maint).
* The logic to find the ref transaction hook script attempted to
cache the path to the found hook without realizing that it needed
to keep a copied value, as the API it used returned a transitory
buffer space. This has been corrected.
(merge 09b2aa30c9 ps/ref-transaction-hook later to maint).
* Recent versions of "git diff-files" shows a diff between the index
and the working tree for "intent-to-add" paths as a "new file"
patch; "git apply --cached" should be able to take "git diff-files"
and should act as an equivalent to "git add" for the path, but the
command failed to do so for such a path.
(merge 4c025c667e rp/apply-cached-with-i-t-a later to maint).
* "git diff [<tree-ish>] $path" for a $path that is marked with i-t-a
bit was not showing the mode bits from the working tree.
(merge cb0dd22b82 rp/ita-diff-modefix later to maint).
* Ring buffer with size 4 used for bin-hex translation resulted in a
wrong object name in the sequencer's todo output, which has been
corrected.
(merge 5da69c0dac ak/sequencer-fix-find-uniq-abbrev later to maint).
* When given more than one target line ranges, "git blame -La,b
-Lc,d" was over-eager to coalesce groups of original lines and
showed incorrect results, which has been corrected.
(merge c2ebaa27d6 jk/blame-coalesce-fix later to maint).
* The regexp to identify the function boundary for FORTRAN programs
has been updated.
(merge 75c3b6b2e8 pb/userdiff-fortran-update later to maint).
* A few end-user facing messages have been updated to be
hash-algorithm agnostic.
(merge 4279000d3e jc/object-names-are-not-sha-1 later to maint).
* "unlink" emulation on MinGW has been optimized.
(merge 680e0b4524 jh/mingw-unlink later to maint).
* The purpose of "git init --separate-git-dir" is to initialize a
new project with the repository separate from the working tree,
or, in the case of an existing project, to move the repository
(the .git/ directory) out of the working tree. It does not make
sense to use --separate-git-dir with a bare repository for which
there is no working tree, so disallow its use with bare
repositories.
(merge ccf236a23a es/init-no-separate-git-dir-in-bare later to maint).
* "ls-files -o" mishandled the top-level directory of another git
working tree that hangs in the current git working tree.
(merge ab282aa548 en/dir-nonbare-embedded later to maint).
* Fix some incorrect UNLEAK() annotations.
(merge 3e19816dc0 jk/unleak-fixes later to maint).
* Use more buffered I/O where we used to call many small write(2)s.
(merge a698d67b08 rs/more-buffered-io later to maint).
* The patch-id computation did not ignore the "incomplete last line"
marker like whitespaces.
(merge 82a62015a7 rs/patch-id-with-incomplete-line later to maint).
* Updates into a lazy/partial clone with a submodule did not work
well with transfer.fsckobjects set.
* The parser for "git for-each-ref --format=..." was too loose when
parsing the "%(trailers...)" atom, and forgot that "trailers" and
"trailers:<modifiers>" are the only two allowed forms, which has
been corrected.
(merge 2c22e102f8 hv/ref-filter-trailers-atom-parsing-fix later to maint).
* Long ago, we decided to use 3 threads by default when running the
index-pack task in parallel, which has been adjusted a bit upwards.
(merge fbff95b67f jk/index-pack-w-more-threads later to maint).
* "git restore/checkout --no-overlay" with wildcarded pathspec
mistakenly removed matching paths in subdirectories, which has been
corrected.
(merge bfda204ade rs/checkout-no-overlay-pathspec-fix later to maint).
* The description of --cached/--index options in "git apply --help"
has been updated.
(merge d064702be3 rp/apply-cached-doc later to maint).
* Feeding "$ZERO_OID" to "git log --ignore-missing --stdin", and
running "git log --ignore-missing $ZERO_OID" fell back to start
digging from HEAD; it has been corrected to become a no-op, like
"git log --tags=no-tag-matches-this-pattern" does.
(merge 04a0e98515 jk/rev-input-given-fix later to maint).
* Various callers of run_command API have been modernized.
(merge afbdba391e jc/run-command-use-embedded-args later to maint).
* List of options offered and accepted by "git add -i/-p" were
inconsistent, which have been corrected.
(merge ce910287e7 pw/add-p-allowed-options-fix later to maint).
* "git diff --stat -w" showed 0-line changes for paths whose changes
were only whitespaces, which was not intuitive. We now omit such
paths from the stat output.
(merge 1cf3d5db9b mr/diff-hide-stat-wo-textual-change later to maint).
* It was possible for xrealloc() to send a non-NULL pointer that has
been freed, which has been fixed.
(merge 6479ea4a8a jk/xrealloc-avoid-use-after-free later to maint).
* "git status" has trouble showing where it came from by interpreting
reflog entries that record certain events, e.g. "checkout @{u}", and
gives a hard/fatal error. Even though it inherently is impossible
to give a correct answer because the reflog entries lose some
information (e.g. "@{u}" does not record what branch the user was
on hence which branch 'the upstream' needs to be computed, and even
if the record were available, the relationship between branches may
have changed), at least hide the error and allow "status" to show its
output.
* "git status --short" quoted a path with SP in it when tracked, but
not those that are untracked, ignored or unmerged. They are all
shown quoted consistently.
* "git diff/show" on a change that involves a submodule used to read
the information on commits in the submodule from a wrong repository
and gave a wrong information when the commit-graph is involved.
(merge 85a1ec2c32 mf/submodule-summary-with-correct-repository later to maint).
* Unlike "git config --local", "git config --worktree" did not fail
early and cleanly when started outside a git repository.
(merge 378fe5fc3d mt/config-fail-nongit-early later to maint).
* There is a logic to estimate how many objects are in the
repository, which is meant to run once per process invocation, but
it ran every time the estimated value was requested.
(merge 67bb65de5d jk/dont-count-existing-objects-twice later to maint).
* "git remote set-head" that failed still said something that hints
the operation went through, which was misleading.
(merge 5a07c6c3c2 cs/don-t-pretend-a-failed-remote-set-head-succeeded later to maint).
* "git fetch --all --ipv4/--ipv6" forgot to pass the protocol options
to instances of the "git fetch" that talk to individual remotes,
which has been corrected.
(merge 4e735c1326 ar/fetch-ipversion-in-all later to maint).
* The "unshelve" subcommand of "git p4" incorrectly used commit^N
where it meant to say commit~N to name the Nth generation
ancestor, which has been corrected.
(merge 0acbf5997f ld/p4-unshelve-fix later to maint).
* "git clone" that clones from SHA-1 repository, while
GIT_DEFAULT_HASH set to use SHA-256 already, resulted in an
unusable repository that half-claims to be SHA-256 repository
with SHA-1 objects and refs. This has been corrected.
* Adjust sample hooks for hash algorithm other than SHA-1.
(merge d8d3d632f4 dl/zero-oid-in-hooks later to maint).
* "git range-diff" showed incorrect diffstat, which has been
corrected.
* Earlier we taught "git pull" to warn when the user does not say the
histories need to be merged, rebased or accepts only fast-
forwarding, but the warning triggered for those who have set the
pull.ff configuration variable.
(merge 54200cef86 ah/pull later to maint).
* Compilation fix around type punning.
(merge 176380fd11 jk/drop-unaligned-loads later to maint).
* "git blame --ignore-rev/--ignore-revs-file" failed to validate
their input are valid revision, and failed to take into account
that the user may want to give an annotated tag instead of a
commit, which has been corrected.
(merge 610e2b9240 jc/blame-ignore-fix later to maint).
* "git bisect start X Y", when X and Y are not valid committish
object names, should take X and Y as pathspec, but didn't.
(merge 73c6de06af cc/bisect-start-fix later to maint).
* The explanation of the "scissors line" has been clarified.
(merge 287416dba6 eg/mailinfo-doc-scissors later to maint).
* A race that leads to an access to a free'd data was corrected in
the codepath that reads pack files.
(merge bda959c476 mt/delta-base-cache-races later to maint).
* in_merge_bases_many(), a way to see if a commit is reachable from
any commit in a set of commits, was totally broken when the
commit-graph feature was in use, which has been corrected.
(merge 8791bf1841 ds/in-merge-bases-many-optim-bug later to maint).
* "git submodule update --quiet" did not squelch underlying "rebase"
and "pull" commands.
(merge 3ad0401e9e td/submodule-update-quiet later to maint).
* The lazy fetching done internally to make missing objects available
in a partial clone incorrectly made permanent damage to the partial
clone filter in the repository, which has been corrected.
* "log -c --find-object=X" did not work well to find a merge that
involves a change to an object X from only one parent.
(merge 957876f17d jk/diff-cc-oidfind-fix later to maint).
* Other code cleanup, docfix, build fix, etc.

Git 2.27 Release Notes
======================
Updates since v2.26
-------------------
Backward compatibility notes
* When "git describe C" finds that commit C is pointed by a signed or
annotated tag, which records T as its tagname in the object, the
command gives T as its answer. Even if the user renames or moves
such a tag from its natural location in the "refs/tags/" hierarchy,
"git describe C" would still give T as the answer, but in such a
case "git show T^0" would no longer work as expected. There may be
nothing at "refs/tags/T" or even worse there may be a different tag
instead.
Starting from this version, "git describe" will always use the
"long" version, as if the "--long" option were given, when giving
its output based on such a misplaced tag to work around the problem.
* "git pull" issues a warning message until the pull.rebase
configuration variable is explicitly given, which some existing
users may find annoying---those who prefer not to rebase need to
set the variable to false to squelch the warning.
* The transport protocol version 2, which was promoted to the default
in Git 2.26 release, turned out to have some remaining rough edges,
so it has been demoted from the default.
UI, Workflows & Features
* A handful of options to configure SSL when talking to proxies have
been added.
* Smudge/clean conversion filters are now given more information
(e.g. the object of the tree-ish in which the blob being converted
appears, in addition to its path, which has already been given).
* When "git describe C" finds an annotated tag with tagname A to be
the best name to explain commit C, and the tag is stored in a
"wrong" place in the refs/tags hierarchy, e.g. refs/tags/B, the
command gave a warning message but used A (not B) to describe C.
If C is exactly at the tag, the describe output would be "A", but
"git rev-parse A^0" would not be equal as "git rev-parse C^0". The
behavior of the command has been changed to use the "long" form
i.e. A-0-gOBJECTNAME, which is correctly interpreted by rev-parse.
* "git pull" learned to warn when no pull.rebase configuration
exists, and neither --[no-]rebase nor --ff-only is given (which
would result a merge).
* "git p4" learned four new hooks and also "--no-verify" option to
bypass them (and the existing "p4-pre-submit" hook).
* "git pull" shares many options with underlying "git fetch", but
some of them were not documented and some of those that would make
sense to pass down were not passed down.
* "git rebase" learned the "--no-gpg-sign" option to countermand
commit.gpgSign the user may have.
* The output from "git format-patch" uses RFC 2047 encoding for
non-ASCII letters on From: and Subject: headers, so that it can
directly be fed to e-mail programs. A new option has been added
to produce these headers in raw.
* "git log" learned "--show-pulls" that helps pathspec limited
history views; a merge commit that takes the whole change from a
side branch, which is normally omitted from the output, is shown
in addition to the commits that introduce real changes.
* The interactive input from various codepaths are consolidated and
any prompt possibly issued earlier are fflush()ed before we read.
* Allow "git rebase" to reapply all local commits, even if the may be
already in the upstream, without checking first.
* The 'pack.useSparse' configuration variable now defaults to 'true',
enabling an optimization that has been experimental since Git 2.21.
* "git rebase" happens to call some hooks meant for "checkout" and
"commit" by this was not a designed behaviour than historical
accident. This has been documented.
* "git merge" learns the "--autostash" option.
* "sparse-checkout" UI improvements.
* "git update-ref --stdin" learned a handful of new verbs to let the
user control ref update transactions more explicitly, which helps
as an ingredient to implement two-phase commit-style atomic
ref-updates across multiple repositories.
* "git commit-graph write" learned different ways to write out split
files.
* Introduce an extension to the commit-graph to make it efficient to
check for the paths that were modified at each commit using Bloom
filters.
* The approxidate parser learns to parse seconds with fraction and
ignore fractional part.
* The userdiff patterns for Markdown documents have been added.
* The sparse-checkout patterns have been forbidden from excluding all
paths, leaving an empty working tree, for a long time. This
limitation has been lifted.
* "git restore --staged --worktree" now defaults to take the contents
out of "HEAD", instead of erring out.
* "git p4" learned to recover from a (broken) state where a directory
and a file are recorded at the same path in the Perforce repository
the same way as their clients do.
* "git multi-pack-index repack" has been taught to honor some
repack.* configuration variables.
Performance, Internal Implementation, Development Support etc.
* The advise API has been revamped to allow more systematic enumeration of
advice knobs in the future.
* SHA-256 transition continues.
* The code to interface with GnuPG has been refactored.
* "git stash" has kept an escape hatch to use the scripted version
for a few releases, which got stale. It has been removed.
* Enable tests that require GnuPG on Windows.
* Minor test usability improvement.
* Trace2 enhancement to allow logging of the environment variables.
* Test clean-up continues.
* Perf-test update.
* A Windows-specific test element has been made more robust against
misuse from both user's environment and programmer's errors.
* Various tests have been updated to work around issues found with
shell utilities that come with busybox etc.
* The config API made mixed uses of int and size_t types to represent
length of various pieces of text it parsed, which has been updated
to use the correct type (i.e. size_t) throughout.
* The "--decorate-refs" and "--decorate-refs-exclude" options "git
log" takes have learned a companion configuration variable
log.excludeDecoration that sits at the lowest priority in the
family.
* A new CI job to build and run test suite on linux with musl libc
has been added.
* Update the CI configuration to use GitHub Actions, retiring the one
based on Azure Pipelines.
* The directory traversal code had redundant recursive calls which
made its performance characteristics exponential with respect to
the depth of the tree, which was corrected.
* "git blame" learns to take advantage of the "changed-paths" Bloom
filter stored in the commit-graph file.
* The "bugreport" tool has been added.
* The object walk with object filter "--filter=tree:0" can now take
advantage of the pack bitmap when available.
* Instead of always building all branches at GitHub via Actions,
users can specify which branches to build.
* Codepaths that show progress meter have been taught to also use the
start_progress() and the stop_progress() calls as a "region" to be
traced.
* Instead of downloading Windows SDK for CI jobs for windows builds
from an external site (wingit.blob.core.windows.net), use the one
created in the windows-build job, to work around quota issues at
the external site.

Git 2.25 Release Notes
======================
Updates since v2.24
-------------------
Backward compatibility notes
UI, Workflows & Features
* A tutorial on object enumeration has been added.
* The branch description ("git branch --edit-description") has been
used to fill the body of the cover letters by the format-patch
command; this has been enhanced so that the subject can also be
filled.
* "git rebase --preserve-merges" has been marked as deprecated; this
release stops advertising it in the "git rebase -h" output.
* The code to generate multi-pack index learned to show (or not to
show) progress indicators.
* "git apply --3way" learned to honor merge.conflictStyle
configuration variable, like merges would.
* The custom format for "git log --format=<format>" learned the l/L
placeholder that is similar to e/E that fills in the e-mail
address, but only the local part on the left side of '@'.
* Documentation pages for "git shortlog" now list commit limiting
options explicitly.
* The patterns to detect function boundary for Elixir language has
been added.
* The completion script (in contrib/) learned that the "--onto"
option of "git rebase" can take its argument as the value of the
option.
* The userdiff machinery has been taught that "async def" is another
way to begin a "function" in Python.
* "git range-diff" learned to take the "--notes=<ref>" and the
"--no-notes" options to control the commit notes included in the
log message that gets compared.
* "git rev-parse --show-toplevel" run outside of any working tree did
not error out, which has been corrected.
* A few commands learned to take the pathspec from the standard input
or a named file, instead of taking it as the command line
arguments, with the "--pathspec-from-file" option.
* "git submodule" learned a subcommand "set-url".
* "git log" family learned "--pretty=reference" that gives the name
of a commit in the format that is often used to refer to it in log
messages.
* The interaction between "git clone --recurse-submodules" and
alternate object store was ill-designed. The documentation and
code have been taught to make more clear recommendations when the
users see failures.
* Management of sparsely checked-out working tree has gained a
dedicated "sparse-checkout" command.
* Miscellaneous small UX improvements on "git-p4".
* "git sparse-checkout list" subcommand learned to give its output in
a more concise form when the "cone" mode is in effect.
Performance, Internal Implementation, Development Support etc.
* Debugging support for lazy cloning has been a bit improved.
* Move the definition of a set of bitmask constants from 0ctal
literal to (1U<<count) notation.
* Test updates to prepare for SHA-2 transition continues.
* Crufty code and logic accumulated over time around the object
parsing and low-level object access used in "git fsck" have been
cleaned up.
* The implementation of "git log --graph" got refactored and then its
output got simplified.
* Follow recent push to move API docs from Documentation/ to header
files and update config.h
* "git bundle" has been taught to use the parse options API. "git
bundle verify" learned "--quiet" and "git bundle create" learned
options to control the progress output.
* Handling of commit objects that use non UTF-8 encoding during
"rebase -i" has been improved.
* The beginning of rewriting "git add -i" in C.
* A label used in the todo list that are generated by "git rebase
--rebase-merges" is used as a part of a refname; the logic to come
up with the label has been tightened to avoid names that cannot be
used as such.
* The logic to avoid duplicate label names generated by "git rebase
--rebase-merges" forgot that the machinery itself uses "onto" as a
label name, which must be avoided by auto-generated labels, which
has been corrected.
* We have had compatibility fallback macro definitions for "PRIuMAX",
"PRIu32", etc. but did not for "PRIdMAX", while the code used the
last one apparently without any hiccup reported recently. The
fallback macro definitions for these <inttypes.h> macros that must
appear in C99 systems have been removed.
* Recently we have declared that GIT_TEST_* variables take the
usual boolean values (it used to be that some used "non-empty
means true" and taking GIT_TEST_VAR=YesPlease as true); make
sure we notice and fail when non-bool strings are given to
these variables.
* Users of oneway_merge() (like "reset --hard") learned to take
advantage of fsmonitor to avoid unnecessary lstat(2) calls.
* Performance tweak on "git push" into a repository with many refs
that point at objects we have never heard of.
* PerfTest fix to avoid stale result mixed up with the latest round
of test results.
* Hide lower-level verify_signed-buffer() API as a pure helper to
implement the public check_signature() function, in order to
encourage new callers to use the correct and more strict
validation.
* Unnecessary reading of state variables back from the disk during
sequencer operation has been reduced.
* The code has been made to avoid gmtime() and localtime() and prefer
their reentrant counterparts.
* In a repository with many packfiles, the cost of the procedure that
avoids registering the same packfile twice was unnecessarily high
by using an inefficient search algorithm, which has been corrected.
* Redo "git name-rev" to avoid recursive calls.
* FreeBSD CI support via Cirrus-CI has been added.
Fixes since v2.24
-----------------
* "rebase -i" ceased to run post-commit hook by mistake in an earlier
update, which has been corrected.
* "git notes copy $original" ought to copy the notes attached to the
original object to HEAD, but a mistaken tightening to command line
parameter validation made earlier disabled that feature by mistake.
* When all files from some subdirectory were renamed to the root
directory, the directory rename heuristics would fail to detect that
as a rename/merge of the subdirectory to the root directory, which has
been corrected.
* Code clean-up and a bugfix in the logic used to tell worktree local
and repository global refs apart.
* "git stash save" in a working tree that is sparsely checked out
mistakenly removed paths that are outside the area of interest.
* "git rev-parse --git-path HEAD.lock" did not give the right path
when run in a secondary worktree.
* "git merge --no-commit" needs "--no-ff" if you do not want to move
HEAD, which has been corrected in the manual page for "git bisect".
* "git worktree add" internally calls "reset --hard" that should not
descend into submodules, even when submodule.recurse configuration
is set, but it was affected. This has been corrected.
* Messages from die() etc. can be mixed up from multiple processes
without even line buffering on Windows, which has been worked
around.
* HTTP transport had possible allocator/deallocator mismatch, which
has been corrected.
* The watchman integration for fsmonitor was racy, which has been
corrected to be more conservative.
* Fetching from multiple remotes into the same repository in parallel
had a bad interaction with the recent change to (optionally) update
the commit-graph after a fetch job finishes, as these parallel
fetches compete with each other. Which has been corrected.
* Recent update to "git stash pop" made the command empty the index
when run with the "--quiet" option, which has been corrected.
* "git fetch" codepath had a big "do not lazily fetch missing objects
when I ask if something exists" switch. This has been corrected by
marking the "does this thing exist?" calls with "if not please do not
lazily fetch it" flag.
* Test update to avoid wasted cycles.
* Error handling after "git push" finishes sending the packdata and
waits for the response to the remote side has been improved.
* Some codepaths in "gitweb" that forgot to escape URLs generated
based on end-user input have been corrected.
* CI jobs for macOS has been made less chatty when updating perforce
package used during testing.
* "git unpack-objects" used to show progress based only on the number
of received and unpacked objects, which stalled when it has to
handle an unusually large object. It now shows the throughput as
well.
* The sequencer machinery compared the HEAD and the state it is
attempting to commit to decide if the result would be a no-op
commit, even when amending a commit, which was incorrect, and
has been corrected.
* The code to parse GPG output used to assume incorrectly that the
finterprint for the primary key would always be present for a valid
signature, which has been corrected.
* "git submodule status" and "git submodule status --cached" show
different things, but the documentation did not cover them
correctly, which has been corrected.
* "git reset --patch $object" without any pathspec should allow a
tree object to be given, but incorrectly required a committish,
which has been corrected.
* "git submodule status" that is run from a subdirectory of the
superproject did not work well, which has been corrected.
* The revision walking machinery uses resources like per-object flag
bits that need to be reset before a new iteration of walking
begins, but the resources related to topological walk were not
cleared correctly, which has been corrected.
* TravisCI update.
* While running "revert" or "cherry-pick --edit" for multiple
commits, a recent regression incorrectly detected "nothing to
commit, working tree clean", instead of replaying the commits,
which has been corrected.
* Work around a issue where a FD that is left open when spawning a
child process and is kept open in the child can interfere with the
operation in the parent process on Windows.
* One kind of progress messages were always given during commit-graph
generation, instead of following the "if it takes more than two
seconds, show progress" pattern, which has been corrected.
* "git rebase" did not work well when format.useAutoBase
configuration variable is set, which has been corrected.
* The "diff" machinery learned not to lose added/removed blank lines
in the context when --ignore-blank-lines and --function-context are
used at the same time.
* The test on "fast-import" used to get stuck when "fast-import" died
in the middle.
* "git format-patch" can take a set of configured format.notes values
to specify which notes refs to use in the log message part of the
output. The behaviour of this was not consistent with multiple
--notes command line options, which has been corrected.
* "git p4" used to ignore lfs.storage configuration variable, which
has been corrected.
* Assorted fixes to the directory traversal API.
* Forbid pathnames that the platform's filesystem cannot represent on
MinGW.
* "git rebase --signoff" stopped working when the command was written
in C, which has been corrected.
* An earlier update to Git for Windows declared that a tree object is
invalid if it has a path component with backslash in it, which was
overly strict, which has been corrected. The only protection the
Windows users need is to prevent such path (or any path that their
filesystem cannot check out) from entering the index.
* The code to write split commit-graph file(s) upon fetching computed
bogus value for the parameter used in splitting the resulting
files, which has been corrected.
* Other code cleanup, docfix, build fix, etc.
|
|
Git 2.23 Release Notes
======================
Updates since v2.22
-------------------
Backward compatibility note
* The "--base" option of "format-patch" computed the patch-ids for
prerequisite patches in an unstable way, which has been updated to
compute in a way that is compatible with "git patch-id --stable".
* The "git log" command by default behaves as if the --mailmap option
was given.
UI, Workflows & Features
* The "git fast-export/import" pair has been taught to handle commits
with log messages in encoding other than UTF-8 better.
* In recent versions of Git, per-worktree refs are exposed in
refs/worktrees/<wtname>/ hierarchy, which means that worktree names
must be a valid refname component. The code now sanitizes the names
given to worktrees, to make sure these refs are well-formed.
* "git merge" learned "--quit" option that cleans up the in-progress
merge while leaving the working tree and the index still in a mess.
* "git format-patch" learns a configuration to set the default for
its --notes=<ref> option.
* The code to show args with potential typo that cannot be
interpreted as a commit-ish has been improved.
* "git clone --recurse-submodules" learned to set up the submodules
to ignore commit object names recorded in the superproject gitlink
and instead use the commits that happen to be at the tip of the
remote-tracking branches from the get-go, by passing the new
"--remote-submodules" option.
* The pattern "git diff/grep" use to extract funcname and words
boundary for Matlab has been extend to cover Octave, which is more
or less equivalent.
* "git help git" was hard to discover (well, at least for some
people).
* The pattern "git diff/grep" use to extract funcname and words
boundary for Rust has been added.
* "git status" can be told a non-standard default value for the
"--[no-]ahead-behind" option with a new configuration variable
status.aheadBehind.
* "git fetch" and "git pull" reports when a fetch results in
non-fast-forward updates to let the user notice unusual situation.
The commands learned "--no-show-forced-updates" option to disable
this safety feature.
* Two new commands "git switch" and "git restore" are introduced to
split "checking out a branch to work on advancing its history" and
"checking out paths out of the index and/or a tree-ish to work on
advancing the current history" out of the single "git checkout"
command.
* "git branch --list" learned to always output the detached HEAD as
the first item (when the HEAD is detached, of course), regardless
of the locale.
* The conditional inclusion mechanism learned to base the choice on
the branch the HEAD currently is on.
* "git rev-list --objects" learned the "--no-object-names" option to
squelch the path to the object that is used as a grouping hint for
pack-objects.
* A new tag.gpgSign configuration variable turns "git tag -a" into
"git tag -s".
* "git multi-pack-index" learned expire and repack subcommands.
* "git blame" learned to "ignore" commits in the history, whose
effects (as well as their presence) get ignored.
* "git cherry-pick/revert" learned a new "--skip" action.
* The tips of refs from the alternate object store can be used as
starting point for reachability computation now.
* Extra blank lines in "git status" output have been reduced.
* The commits in a repository can be described by multiple
commit-graph files now, which allows the commit-graph files to be
updated incrementally.
* "git range-diff" output has been tweaked for easier identification
of which part of what file the patch shown is about.
Performance, Internal Implementation, Development Support etc.
* Update supporting parts of "git rebase" to remove code that should
no longer be used.
* Developer support to emulate unsatisfied prerequisites in tests to
ensure that the remainder of the tests still succeeds when tests
with prerequisites are skipped.
* "git update-server-info" learned not to rewrite the file with the
same contents.
* The way of specifying the path to find dynamic libraries at runtime
has been simplified. The old default to pass -R/path/to/dir has been
replaced with the new default to pass -Wl,-rpath,/path/to/dir,
which is the more recent GCC uses. Those who need to build with an
old GCC can still use "CC_LD_DYNPATH=-R"
* Prepare use of reachability index in topological walker that works
on a range (A..B).
* A new tutorial targeting specifically aspiring git-core
developers has been added.
* Auto-detect how to tell HP-UX aCC where to use dynamically linked
libraries from at runtime.
* "git mergetool" and its tests now spawn fewer subprocesses.
* Dev support update to help tracing out tests.
* Support to build with MSVC has been updated.
* "git fetch" that grabs from a group of remotes learned to run the
auto-gc only once at the very end.
* A handful of Windows build patches have been upstreamed.
* The code to read state files used by the sequencer machinery for
"git status" has been made more robust against a corrupt or stale
state files.
* "git for-each-ref" with multiple patterns have been optimized.
* The tree-walk API learned to pass an in-core repository
instance throughout more codepaths.
* When one step in multi step cherry-pick or revert is reset or
committed, the command line prompt script failed to notice the
current status, which has been improved.
* Many GIT_TEST_* environment variables control various aspects of
how our tests are run, but a few followed "non-empty is true, empty
or unset is false" while others followed the usual "there are a few
ways to spell true, like yes, on, etc., and also ways to spell
false, like no, off, etc." convention.
* Adjust the dir-iterator API and apply it to the local clone
optimization codepath.
* We have been trying out a few language features outside c89; the
coding guidelines document did not talk about them and instead had
a blanket ban against them.
* A test helper has been introduced to optimize preparation of test
repositories with many simple commits, and a handful of test
scripts have been updated to use it.
Fixes since v2.22
-----------------
* A relative pathname given to "git init --template=<path> <repo>"
ought to be relative to the directory "git init" gets invoked in,
but it instead was made relative to the repository, which has been
corrected.
* "git worktree add" used to fail when another worktree connected to
the same repository was corrupt, which has been corrected.
* The ownership rule for the file descriptor to fast-import remote
backend was mixed up, leading to an unrelated file descriptor getting
closed, which has been fixed.
* A "merge -c" instruction during "git rebase --rebase-merges" should
give the user a chance to edit the log message, even when there is
otherwise no need to create a new merge and replace the existing
one (i.e. fast-forward instead), but did not. Which has been
corrected.
* Code cleanup and futureproof.
* More parameter validation.
* "git update-server-info" used to leave stale packfiles in its
output, which has been corrected.
* The server side support for "git fetch" used to show incorrect
value for the HEAD symbolic ref when the namespace feature is in
use, which has been corrected.
* "git am -i --resolved" segfaulted after trying to see a commit as
if it were a tree, which has been corrected.
* "git bundle verify" needs to see if prerequisite objects exist in
the receiving repository, but the command did not check if we are
in a repository upfront, which has been corrected.
* "git merge --squash" is designed to update the working tree and the
index without creating the commit, and this cannot be countermanded
by adding the "--commit" option; the command now refuses to work
when both options are given.
* The data collected by fsmonitor was not properly written back to
the on-disk index file, breaking t7519 tests occasionally, which
has been corrected.
* Update to Unicode 12.1 width table.
* The command line to invoke a "git cat-file" command from inside
"git p4" was not properly quoted to protect a caret and running a
broken command on Windows, which has been corrected.
* "git request-pull" learned to warn when the ref we ask them to pull
from in the local repository and in the published repository are
different.
* When creating a partial clone, the object filtering criteria is
recorded for the origin of the clone, but this incorrectly used a
hardcoded name "origin" to name that remote; it has been corrected
to honor the "--origin <name>" option.
* "git fetch" into a lazy clone forgot to fetch base objects that are
necessary to complete delta in a thin packfile, which has been
corrected.
* The filter_data used in the list-objects-filter (which manages a
lazily sparse clone repository) did not use the dynamic array API
correctly---'nr' is supposed to point at one past the last element
of the array in use. This has been corrected.
* The description about slashes in gitignore patterns (used to
indicate things like "anchored to this level only" and "only
matches directories") has been revamped.
* The URL decoding code has been updated to avoid going past the end
of the string while parsing %-<hex>-<hex> sequence.
* The list of for-each like macros used by clang-format has been
updated.
* "git branch --list" learned to show branches that are checked out
in other worktrees connected to the same repository prefixed with
'+', similar to the way the currently checked out branch is shown
with '*' in front.
(merge 6e9381469e nb/branch-show-other-worktrees-head later to maint).
* Code restructuring during 2.20 period broke fetching tags via
"import" based transports.
* The commit-graph file is now part of the "files that the runtime
may keep open file descriptors on, all of which would need to be
closed when done with the object store", and the file descriptor to
an existing commit-graph file now is closed before "gc" finalizes a
new instance to replace it.
* "git checkout -p" needs to selectively apply a patch in reverse,
which did not work well.
* Code clean-up to avoid signed integer wraparounds during binary search.
* "git interpret-trailers" always treated '#' as the comment
character, regardless of core.commentChar setting, which has been
corrected.
* "git stash show 23" used to work, but no more after getting
rewritten in C; this regression has been corrected.
* "git rebase --abort" used to leave refs/rewritten/ when concluding
"git rebase -r", which has been corrected.
* An incorrect list of options was cached after command line
completion failed (e.g. trying to complete a command that requires
a repository outside one), which has been corrected.
* The code to parse scaled numbers out of configuration files has
been made more robust and also easier to follow.
* The codepath to compute delta islands used to spew progress output
without giving the callers any way to squelch it, which has been
fixed.
* Protocol capabilities that go over wire should never be translated,
but it was incorrectly marked for translation, which has been
corrected. The output of protocol capabilities for debugging has
been tweaked a bit.
* Use "Erase in Line" CSI sequence that is already used in the editor
support to clear cruft in the progress output.
* "git submodule foreach" did not protect command line options passed
to the command to be run in each submodule correctly, when the
"--recursive" option was in use.
* The configuration variable rebase.rescheduleFailedExec should be
effective only while running an interactive rebase and should not
affect anything when running a non-interactive one, which was not
the case. This has been corrected.
* The "git clone" documentation refers to command line options in its
description in the short form; they have been replaced with long
forms to make them more recognisable.
* Generation of pack bitmaps are now disabled when .keep files exist,
as these are mutually exclusive features.
(merge 7328482253 ew/repack-with-bitmaps-by-default later to maint).
* "git rm" to resolve a conflicted path leaked an internal message
"needs merge" before actually removing the path, which was
confusing. This has been corrected.
* "git stash --keep-index" did not work correctly on paths that have
been removed, which has been fixed.
(merge b932f6a5e8 tg/stash-keep-index-with-removed-paths later to maint).
* Window 7 update ;-)
* A codepath that reads from GPG for signed object verification read
past the end of allocated buffer, which has been fixed.
* "git clean" silently skipped a path when it cannot lstat() it; now
it gives a warning.
* "git push --atomic" that goes over the transport-helper (namely,
the smart http transport) failed to prevent refs to be pushed when
it can locally tell that one of the ref update will fail without
having to consult the other end, which has been corrected.
* The internal diff machinery can be made to read out of bounds while
looking for --function-context line in a corner case, which has been
corrected.
(merge b777f3fd61 jk/xdiff-clamp-funcname-context-index later to maint).
* Other code cleanup, docfix, build fix, etc.
(merge fbec05c210 cc/test-oidmap later to maint).
(merge 7a06fb038c jk/no-system-includes-in-dot-c later to maint).
(merge 81ed2b405c cb/xdiff-no-system-includes-in-dot-c later to maint).
(merge d61e6ce1dd sg/fsck-config-in-doc later to maint).

Changelog:
Git 2.22 Release Notes
======================
Updates since v2.21
-------------------
Backward compatibility note
* The filter specification "--filter=sparse:path=<path>" used to
create a lazy/partial clone has been removed. Using a blob that is
part of the project as sparse specification is still supported with
the "--filter=sparse:oid=<blob>" option.
UI, Workflows & Features
* "git checkout --no-overlay" can be used to trigger a new mode of
checking out paths out of the tree-ish, that allows paths that
match the pathspec that are in the current index and working tree
and are not in the tree-ish.
* The %(trailers) formatter in "git log --format=..." now allows to
optionally pick trailers selectively by keyword, show only values,
etc.
* Four new configuration variables {author,committer}.{name,email}
have been introduced to override user.{name,email} in more specific
cases.
* Command-line completion (in contrib/) learned to tab-complete the
"git submodule absorbgitdirs" subcommand.
* "git branch" learned a new subcommand "--show-current".
* Output from "diff --cc" did not show the original paths when the
merge involved renames. A new option adds the paths in the
original trees to the output.
* The command line completion (in contrib/) has been taught to
complete more subcommand parameters.
* The final report from "git bisect" used to show the suspected
culprit using a raw "diff-tree", with which there is no output for
a merge commit. This has been updated to use a more modern and
human readable output that still is concise enough.
* "git rebase --rebase-merges" replaces its old "--preserve-merges"
option; the latter is now marked as deprecated.
* Error message given while cloning with --recurse-submodules has
been updated.
* The completion helper code now pays attention to repository-local
configuration (when available), which allows --list-cmds to honour
a repository specific setting of completion.commands, for example.
* "git mergetool" learned to offer Sublime Merge (smerge) as one of
its backends.
* A new hook "post-index-change" is called when the on-disk index
file changes, which can help e.g. a virtualized working tree
implementation.
* "git difftool" can now run outside a repository.
* "git checkout -m <other>" was about carrying the differences
between HEAD and the working-tree files forward while checking out
another branch, and ignored the differences between HEAD and the
index. The command has been taught to abort when the index and the
HEAD are different.
* A progress indicator has been added to the "index-pack" step, which
often makes users wait for completion during "git clone".
* "git submodule" learns "set-branch" subcommand that allows the
submodule.*.branch settings to be modified.
* "git merge-recursive" backend recently learned a new heuristics to
infer file movement based on how other files in the same directory
moved. As this is inherently less robust heuristics than the one
based on the content similarity of the file itself (rather than
based on what its neighbours are doing), it sometimes gives an
outcome unexpected by the end users. This has been toned down to
leave the renamed paths in higher/conflicted stages in the index so
that the user can examine and confirm the result.
* "git tag" learned to give an advice suggesting it might be a
mistake when creating an annotated or signed tag that points at
another tag.
* The "git pack-objects" command learned to report the number of
objects it packed via the trace2 mechanism.
* The list of conflicted paths shown in the editor while concluding a
conflicted merge was shown above the scissors line when the
clean-up mode is set to "scissors", even though it was commented
out just like the list of updated paths and other information to
help the user explain the merge better.
* The trace2 tracing facility learned to auto-generate a filename
when told to log to a directory.
* "git clone" learned a new --server-option option when talking over
the protocol version 2.
* The connectivity bitmaps are created by default in bare
repositories now; also the pathname hash-cache is created by
default to avoid making crappy deltas when repacking.
* "git branch new A...B" and "git checkout -b new A...B" have been
taught that in their contexts, the notation A...B means "the merge
base between these two commits", just like "git checkout A...B"
detaches HEAD at that commit.
* Update "git difftool" and "git mergetool" so that the combinations
of {diff,merge}.{tool,guitool} configuration variables serve as
fallback settings of each other in a sensible order.
* The "--dir-diff" mode of "git difftool" is not useful in "--no-index"
mode; they are now explicitly marked as mutually incompatible.
Performance, Internal Implementation, Development Support etc.
* The diff machinery, one of the oldest parts of the system, which
long predates the parse-options API, uses fairly long and complex
handcrafted option parser. This is being rewritten to use the
parse-options API.
* The implementation of pack-redundant has been updated for
performance in a repository with many packfiles.
* A more structured way to obtain execution trace has been added.
* "git prune" has been taught to take advantage of reachability
bitmap when able.
* The command line parser of "git commit-tree" has been rewritten to
use the parse-options API.
* Suggest GitGitGadget instead of submitGit as a way to submit
patches based on GitHub PR to us.
* The test framework has been updated to help developers by making it
easier to run most of the tests under different versions of
over-the-wire protocols.
* Dev support update to make it easier to compare two formatted
results from our documentation.
* The scripted "git rebase" implementation has been retired.
* "git multi-pack-index verify" did not scale well with the number of
packfiles, which is being improved.
* "git stash" has been rewritten in C.
* The "check-docs" Makefile target to support developers has been
updated.
* The tests have been updated not to rely on the abbreviated option
names the parse-options API offers, to protect us from an
abbreviated form of an option that used to be unique within the
command getting non-unique when a new option that share the same
prefix is added.
* The scripted version of "git rebase -i" wrote and rewrote the todo
list many times during a single step of its operation, and the
recent C-rewrite made a faithful conversion of the logic to C. The
implementation has been updated to carry necessary information
around in-core to avoid rewriting the same file over and over
unnecessarily.
* Test framework update to more robustly clean up leftover files and
processes after tests are done.
* Conversion from unsigned char[20] to struct object_id continues.
* While running "git diff" in a lazy clone, we can upfront know which
missing blobs we will need, instead of waiting for the on-demand
machinery to discover them one by one. The code learned to aim to
achieve better performance by batching the request for these
promised blobs.
* During an initial "git clone --depth=..." partial clone, it is
pointless to spend cycles for a large portion of the connectivity
check that enumerates and skips promisor objects (which by
definition is all objects fetched from the other side). This has
been optimized out.
* Mechanically and systematically drop "extern" from function
declaration.
* The script to aggregate perf result unconditionally depended on
libjson-perl even though it did not have to, which has been
corrected.
* The internal implementation of "git rebase -i" has been updated to
avoid forking a separate "rebase--interactive" process.
* Allow DEP and ASLR for Windows build to for security hardening.
* Performance test framework has been broken and measured the version
of Git that happens to be on $PATH, not the specified one to
measure, for a while, which has been corrected.
* Optionally "make coccicheck" can feed multiple source files to
spatch, gaining performance while spending more memory.
* Attempt to use an abbreviated option in "git clone --recurs" is
responded by a request to disambiguate between --recursive and
--recurse-submodules, which is bad because these two are synonyms.
The parse-options API has been extended to define such synonyms
more easily and not produce an unnecessary failure.
* A pair of private functions in http.c that had names similar to
fread/fwrite did not return the number of elements, which was found
to be confusing.
* Update collision-detecting SHA-1 code to build properly on HP-UX.
Fixes since v2.21
-----------------
* "git prune-packed" did not notice and complain against excess
arguments given from the command line, which now it does.
(merge 9b0bd87ed2 rj/prune-packed-excess-args later to maint).
* Split-index fix.
(merge 6e37c8ed3c nd/split-index-null-base-fix later to maint).
* "git diff --no-index" may still want to access Git goodies like
--ext-diff and --textconv, but so far these have been ignored,
which has been corrected.
(merge 287ab28bfa jk/diff-no-index-initialize later to maint).
* Unify RPC code for smart http in protocol v0/v1 and v2, which fixes
a bug in the latter (lack of authentication retry) and generally
improves the code base.
(merge a97d00799a jt/http-auth-proto-v2-fix later to maint).
* The include file compat/bswap.h has been updated so that it is safe
to (accidentally) include it more than once.
(merge 33aa579a55 jk/guard-bswap-header later to maint).
* The set of header files used by "make hdr-check" unconditionally
included sha256/gcrypt.h, even when it is not used, causing the
make target to fail. We now skip it when GCRYPT_SHA256 is not in
use.
(merge f23aa18e7f rj/hdr-check-gcrypt-fix later to maint).
* The Makefile uses 'find' utility to enumerate all the *.h header
files, which is expensive on platforms with slow filesystems; it
now optionally uses "ls-files" if working within a repository,
which is a trick similar to how all sources are enumerated to run
ETAGS on.
(merge 92b88eba9f js/find-lib-h-with-ls-files-when-possible later to maint).
* "git rebase" that was reimplemented in C did not set ORIG_HEAD
correctly, which has been corrected.
(merge cbd29ead92 js/rebase-orig-head-fix later to maint).
* Dev support.
(merge f545737144 js/stress-test-ui-tweak later to maint).
* CFLAGS now can be tweaked when invoking Make while using
DEVELOPER=YesPlease; this did not work well before.
(merge 6d5d4b4e93 ab/makefile-help-devs-more later to maint).
* "git fsck --connectivity-only" omits computation necessary to sift
the objects that are not reachable from any of the refs into
unreachable and dangling. This is now enabled when dangling
objects are requested (which is done by default, but can be
overridden with the "--no-dangling" option).
(merge 8d8c2a5aef jk/fsck-doc later to maint).
* On platforms where "git fetch" is killed with SIGPIPE (e.g. OSX),
the upload-pack that runs on the other end that hangs up after
detecting an error could cause "git fetch" to die with a signal,
which led to a flaky test. "git fetch" now ignores SIGPIPE during
the network portion of its operation (this is not a problem as we
check the return status from our write(2)s).
(merge 143588949c jk/no-sigpipe-during-network-transport later to maint).
* A recent update broke "is this object available to us?" check for
well-known objects like an empty tree (which should yield "yes",
even when there is no on-disk object for an empty tree), which has
been corrected.
(merge f06ab027ef jk/virtual-objects-do-exist later to maint).
* The setup code has been cleaned up to avoid leaks around the
repository_format structure.
(merge e8805af1c3 ma/clear-repository-format later to maint).
* "git config --type=color ..." is meant to replace "git config --get-color"
but there is a slight difference that wasn't documented, which is
now fixed.
(merge cd8e7593b9 jk/config-type-color-ends-with-lf later to maint).
* When the "clean" filter can reduce the size of a huge file in the
working tree down to a small "token" (a la Git LFS), there is no
point in allocating a huge scratch area upfront, but the buffer is
sized based on the original file size. The convert mechanism now
allocates very minimum and reallocates as it receives the output
from the clean filter process.
(merge 02156ab031 jh/resize-convert-scratch-buffer later to maint).
* "git rebase" uses the refs/rewritten/ hierarchy to store its
intermediate states, which inherently makes the hierarchy per
worktree, but it didn't quite work well.
(merge b9317d55a3 nd/rewritten-ref-is-per-worktree later to maint).
* "git log -L<from>,<to>:<path>" with "-s" did not suppress the patch
output as it should. This has been corrected.
(merge 05314efaea jk/line-log-with-patch later to maint).
* "git worktree add" used to do a "find an available name with stat
and then mkdir", which is race-prone. This has been fixed by using
mkdir and reacting to EEXIST in a loop.
(merge 7af01f2367 ms/worktree-add-atomic-mkdir later to maint).
* Build update for SHA-1 with collision detection.
(merge 07a20f569b jk/sha1dc later to maint).
* Build procedure has been fixed around use of asciidoctor instead of
asciidoc.
(merge 185f9a0ea0 ma/asciidoctor-fixes later to maint).
* remote-http transport did not anonymize URLs reported in its error
messages at places.
(merge c1284b21f2 js/anonymize-remote-curl-diag later to maint).
* Error messages given from the http transport have been updated so
that they can be localized.
(merge ed8b4132c8 js/remote-curl-i18n later to maint).
* "git init" forgot to read platform-specific repository
configuration, which made Windows port to ignore settings of
core.hidedotfiles, for example.
* A corner-case object name ambiguity while the sequencer machinery
is working (e.g. "rebase -i -x") has been fixed.
* "git format-patch" did not diagnose an error while opening the
output file for the cover-letter, which has been corrected.
(merge 2fe95f494c jc/format-patch-error-check later to maint).
* "git checkout -f <branch>" while the index has an unmerged path
incorrectly left some paths in an unmerged state, which has been
corrected.
* A corner case bug in the refs API has been corrected.
(merge d3322eb28b jk/refs-double-abort later to maint).
* Unicode update.
(merge 584b62c37b bb/unicode-12 later to maint).
* dumb-http walker has been updated to share more error recovery
strategy with the normal codepath.
* A buglet in configuration parser has been fixed.
(merge 19e7fdaa58 nd/include-if-wildmatch later to maint).
* The documentation for "git read-tree --reset -u" has been updated.
(merge b5a0bd694c nd/read-tree-reset-doc later to maint).
* Code clean-up around a much-less-important-than-it-used-to-be
update_server_info() function.
(merge b3223761c8 jk/server-info-rabbit-hole later to maint).
* The message given when "git commit -a <paths>" errors out has been
updated.
(merge 5a1dbd48bc nd/commit-a-with-paths-msg-update later to maint).
* "git cherry-pick --options A..B", after giving control back to the
user to ask help resolving a conflicted step, did not honor the
options it originally received, which has been corrected.
* Various glitches in "git gc" around reflog handling have been fixed.
* The code to read from commit-graph file has been cleanup with more
careful error checking before using data read from it.
* Performance fix around "git fetch" that grabs many refs.
(merge b764300912 jt/fetch-pack-wanted-refs-optim later to maint).
* Protocol v2 support in "git fetch-pack" of shallow clones has been
corrected.
* Performance fix around "git blame", especially in a linear history
(which is the norm we should optimize for).
(merge f892014943 dk/blame-keep-origin-blob later to maint).
* Performance fix for "rev-list --parents -- pathspec".
(merge 8320b1dbe7 jk/revision-rewritten-parents-in-prio-queue later to maint).
* Updating the display with progress message has been cleaned up to
deal better with overlong messages.
(merge 545dc345eb sg/overlong-progress-fix later to maint).
* "git blame -- path" in a non-bare repository starts blaming from
the working tree, and the same command in a bare repository errors
out because there is no working tree by definition. The command
has been taught to instead start blaming from the commit at HEAD,
which is more useful.
(merge a544fb08f8 sg/blame-in-bare-start-at-head later to maint).
* An underallocation in the code to read the untracked cache
extension has been corrected.
(merge 3a7b45a623 js/untracked-cache-allocfix later to maint).
* The code is updated to check the result of memory allocation before
it is used in more places, by using xmalloc and/or xcalloc calls.
(merge 999b951b28 jk/xmalloc later to maint).
* The GETTEXT_POISON test option has been quite broken ever since it
was made runtime-tunable, which has been fixed.
(merge f88b9cb603 jc/gettext-test-fix later to maint).
* Test fix on APFS that is incapable of store paths in Latin-1.
(merge 3889149619 js/iso8895-test-on-apfs later to maint).
* "git submodule foreach <command> --quiet" did not pass the option
down correctly, which has been corrected.
(merge a282f5a906 nd/submodule-foreach-quiet later to maint).
* "git send-email" has been taught to use quoted-printable when the
payload contains carriage-return. The use of the mechanism is in
line with the design originally added the codepath that chooses QP
when the payload has overly long lines.
(merge 74d76a1701 bc/send-email-qp-cr later to maint).
* The recently added feature to add addresses that are on
anything-by: trailers in 'git send-email' was found to be way too
eager and considered nonsense strings as if they can be legitimate
beginning of *-by: trailer. This has been tightened.
* Builds with gettext broke on recent macOS w/ Homebrew, which
seems to have stopped including from /usr/local/include; this
has been corrected.
(merge 92a1377a2a js/macos-gettext-build later to maint).
* Running "git add" on a repository created inside the current
repository is an explicit indication that the user wants to add it
as a submodule, but when the HEAD of the inner repository is on an
unborn branch, it cannot be added as a submodule. Worse, the files
in its working tree can be added as if they are a part of the outer
repository, which is not what the user wants. These problems are
being addressed.
(merge f937bc2f86 km/empty-repo-is-still-a-repo later to maint).
* "git cherry-pick" run with the "-x" or the "--signoff" option used
to (and more importantly, ought to) clean up the commit log message
with the --cleanup=space option by default, but this has been
broken since late 2017. This has been fixed.
* When given a tag that points at a commit-ish, "git replace --graft"
failed to peel the tag before writing a replace ref, which did not
make sense because the old graft mechanism the feature wants to
mimic only allowed to replace one commit object with another.
This has been fixed.
(merge ee521ec4cb cc/replace-graft-peel-tags later to maint).
* Code tightening against a "wrong" object appearing where an object
of a different type is expected, instead of blindly assuming that
the connection between objects are correctly made.
(merge 97dd512af7 tb/unexpected later to maint).
* An earlier update for MinGW and Cygwin accidentally broke MSVC build,
which has been fixed.
(merge 22c3634c0f ss/msvc-path-utils-fix later to maint).
* %(push:track) token used in the --format option to "git
for-each-ref" and friends was not showing the right branch, which
has been fixed.
(merge c646d0934e dr/ref-filter-push-track-fix later to maint).
* "make check-docs", "git help -a", etc. did not account for cases
where a particular build may deliberately omit some subcommands,
which has been corrected.
* The logic to tell if a Git repository has a working tree protects
"git branch -D" from removing the branch that is currently checked
out by mistake. The implementation of this logic was broken for
repositories with unusual name, which unfortunately is the norm for
submodules these days. This has been fixed.
(merge f3534c98e4 jt/submodule-repo-is-with-worktree later to maint).
* AIX shared the same build issues with other BSDs around fileno(fp),
which has been corrected.
(merge ee662bf5c6 cc/aix-has-fileno-as-a-macro later to maint).
* The autoconf generated configure script failed to use the right
gettext() implementations from -libintl by ignoring useless stub
implementations shipped in some C library, which has been
corrected.
(merge b71e56a683 vk/autoconf-gettext later to maint).
* Fix index-pack perf test so that the repeated invocations always
run in an empty repository, which emulates the initial clone
situation better.
(merge 775c71e16d jk/p5302-avoid-collision-check-cost later to maint).
* A "ls-files" that emulates "find" to enumerate files in the working
tree resulted in duplicated Makefile rules that caused the build to
issue an unnecessary warning during a trial build after merge
conflicts are resolved in working tree *.h files but before the
resolved results are added to the index. This has been corrected.
* "git cherry-pick" (and "revert" that shares the same runtime engine)
that deals with multiple commits got confused when the final step
gets stopped with a conflict and the user concluded the sequence
with "git commit". Attempt to fix it by cleaning up the state
files used by these commands in such a situation.
(merge 4a72486de9 pw/clean-sequencer-state-upon-final-commit later to maint).
* On a filesystem like HFS+, the names of the refs stored as filesystem
entities may become different from what the end-user expects, just
like files in the working tree get "renamed". Work around the
mismatch by paying attention to the core.precomposeUnicode
configuration.
(merge 8e712ef6fc en/unicode-in-refnames later to maint).
* The code to generate the multi-pack idx file was not prepared to
see too many packfiles and ran out of open file descriptor, which
has been corrected.
* To run tests for Git SVN, our scripts for CI used to install the
git-svn package (in the hope that it would bring in the right
dependencies). This has been updated to install the more direct
dependency, namely, libsvn-perl.
(merge db864306cf sg/ci-libsvn-perl later to maint).
* "git cvsexportcommit" running on msys did not expect cvsnt showed
"cvs status" output with CRLF line endings.
* The fsmonitor interface got out of sync after the in-core index
file gets discarded, which has been corrected.
(merge 398a3b0899 js/fsmonitor-refresh-after-discarding-index later to maint).
* "git status" did not know that the "label" instruction in the
todo-list "rebase -i -r" uses should not be shown as a hex object
name.
* A prerequisite check in the test suite to see if a working jgit is
available was made more robust.
(merge abd0f28983 tz/test-lib-check-working-jgit later to maint).
* The codepath to parse :<path> that obtains the object name for an
indexed object has been made more robust.
* Code cleanup, docfix, build fix, etc.

Git 2.20 Release Notes
======================
Backward Compatibility Notes
----------------------------
* "git branch -l <foo>" used to be a way to ask a reflog to be
created while creating a new branch, but that is no longer the
case. It is a short-hand for "git branch --list <foo>" now.
* "git push" into refs/tags/* hierarchy is rejected without getting
forced, but "git fetch" (misguidedly) used the "fast forwarding"
rule used for the refs/heads/* hierarchy; this has been corrected,
which means some fetches of tags that did not fail with older
version of Git will fail without "--force" with this version.
* "git help -a" now gives verbose output (same as "git help -av").
Those who want the old output may say "git help --no-verbose -a"..
* "git cpn --help", when "cpn" is an alias to, say, "cherry-pick -n",
reported only the alias expansion of "cpn" in earlier versions of
Git. It now runs "git cherry-pick --help" to show the manual page
of the command, while sending the alias expansion to the standard
error stream.
* "git send-email" learned to grab address-looking string on any
trailer whose name ends with "-by". This is a backward-incompatible
change. Adding "--suppress-cc=misc-by" on the command line, or
setting sendemail.suppresscc configuration variable to "misc-by",
can be used to disable this behaviour.
Updates since v2.19
-------------------
UI, Workflows & Features
* Running "git clone" against a project that contain two files with
pathnames that differ only in cases on a case insensitive
filesystem would result in one of the files lost because the
underlying filesystem is incapable of holding both at the same
time. An attempt is made to detect such a case and warn.
* "git checkout -b newbranch [HEAD]" should not have to do as much as
checking out a commit different from HEAD. An attempt is made to
optimize this special case.
* "git rev-list --stdin </dev/null" used to be an error; it now shows
no output without an error. "git rev-list --stdin --default HEAD"
still falls back to the given default when nothing is given on the
standard input.
* Lift code from GitHub to restrict delta computation so that an
object that exists in one fork is not made into a delta against
another object that does not appear in the same forked repository.
* "git format-patch" learned new "--interdiff" and "--range-diff"
options to explain the difference between this version and the
previous attempt in the cover letter (or after the three-dashes as
a comment).
* "git mailinfo" used in "git am" learned to make a best-effort
recovery of a patch corrupted by MUA that sends text/plain with
format=flawed option.
(merge 3aa4d81f88 rs/mailinfo-format-flowed later to maint).
* The rules used by "git push" and "git fetch" to determine if a ref
can or cannot be updated were inconsistent; specifically, fetching
to update existing tags were allowed even though tags are supposed
to be unmoving anchoring points. "git fetch" was taught to forbid
updates to existing tags without the "--force" option.
* "git multi-pack-index" learned to detect corruption in the .midx
file it uses, and this feature has been integrated into "git fsck".
* Generation of (experimental) commit-graph files have so far been
fairly silent, even though it takes noticeable amount of time in a
meaningfully large repository. The users will now see progress
output.
* The minimum version of Windows supported by Windows port of Git is
now set to Vista.
* The completion script (in contrib/) learned to complete a handful of
options "git stash list" command takes.
* The completion script (in contrib/) learned that "git fetch
--multiple" only takes remote names as arguments and no refspecs.
* "git status" learns to show progress bar when refreshing the index
takes a long time.
(merge ae9af12287 nd/status-refresh-progress later to maint).
* "git help -a" and "git help -av" give different pieces of
information, and generally the "verbose" version is more friendly
to the new users. "git help -a" by default now uses the more
verbose output (with "--no-verbose", you can go back to the
original). Also "git help -av" now lists aliases and external
commands, which it did not used to.
* Unlike "grep", "git grep" by default recurses to the whole tree.
The command learned "git grep --recursive" option, so that "git
grep --no-recursive" can serve as a synonym to setting the
max-depth to 0.
* When pushing into a repository that borrows its objects from an
alternate object store, "git receive-pack" that responds to the
push request on the other side lists the tips of refs in the
alternate to reduce the amount of objects transferred. This
sometimes is detrimental when the number of refs in the alternate
is absurdly large, in which case the bandwidth saved in potentially
fewer objects transferred is wasted in excessively large ref
advertisement. The alternate refs that are advertised are now
configurable with a pair of configuration variables.
* "git cmd --help" when "cmd" is aliased used to only say "cmd is
aliased to ...". Now it shows that to the standard error stream
and runs "git $cmd --help" where $cmd is the first word of the
alias expansion.
* The documentation of "git gc" has been updated to mention that it
is no longer limited to "pruning away crufts" but also updates
ancillary files like commit-graph as a part of repository
optimization.
* "git p4 unshelve" improvements.
* The logic to select the default user name and e-mail on Windows has
been improved.
(merge 501afcb8b0 js/mingw-default-ident later to maint).
* The "rev-list --filter" feature learned to exclude all trees via
"tree:0" filter.
* "git send-email" learned to grab address-looking string on any
trailer whose name ends with "-by"; --suppress-cc=misc-by on the
command line, or setting sendemail.suppresscc configuration
variable to "misc-by", can be used to disable this behaviour.
* "git mergetool" learned to take the "--[no-]gui" option, just like
"git difftool" does.
* "git rebase -i" learned a new insn, 'break', that the user can
insert in the to-do list. Upon hitting it, the command returns
control back to the user.
* New "--pretty=format:" placeholders %GF and %GP that show the GPG
key fingerprints have been invented.
* On platforms with recent cURL library, http.sslBackend configuration
variable can be used to choose a different SSL backend at runtime.
The Windows port uses this mechanism to switch between OpenSSL and
Secure Channel while talking over the HTTPS protocol.
* "git send-email" learned to disable SMTP authentication via the
"--smtp-auth=none" option, even when the smtp username is given
(which turns the authentication on by default).
* A fourth class of configuration files (in addition to the
traditional "system wide", "per user in the $HOME directory" and
"per repository in the $GIT_DIR/config") has been introduced so
that different worktrees that share the same repository (hence the
same $GIT_DIR/config file) can use different customization.
* A pattern with '**' that does not have a slash on either side used
to be an invalid one, but the code now treats such double-asterisks
the same way as two normal asterisks that happen to be adjacent to
each other.
(merge e5bbe09e88 nd/wildmatch-double-asterisk later to maint).
* The "--no-patch" option, which can be used to get a high-level
overview without the actual line-by-line patch difference shown, of
the "range-diff" command was earlier broken, which has been
corrected.
* The recently merged "rebase in C" has an escape hatch to use the
scripted version when necessary, but it hasn't been documented,
which has been corrected.
Performance, Internal Implementation, Development Support etc.
* Developer builds now use -Wunused-function compilation option.
* One of our CI tests to run with "unusual/experimental/random"
settings now also uses commit-graph and midx.
* When there are too many packfiles in a repository (which is not
recommended), looking up an object in these would require
consulting many pack .idx files; a new mechanism to have a single
file that consolidates all of these .idx files is introduced.
* "git submodule update" is getting rewritten piece-by-piece into C.
* The code for computing history reachability has been shuffled,
obtained a bunch of new tests to cover them, and then being
improved.
* The unpack_trees() API used in checking out a branch and merging
walks one or more trees along with the index. When the cache-tree
in the index tells us that we are walking a tree whose flattened
contents is known (i.e. matches a span in the index), as linearly
scanning a span in the index is much more efficient than having to
open tree objects recursively and listing their entries, the walk
can be optimized, which has been done.
* When creating a thin pack, which allows objects to be made into a
delta against another object that is not in the resulting pack but
is known to be present on the receiving end, the code learned to
take advantage of the reachability bitmap; this allows the server
to send a delta against a base beyond the "boundary" commit.
* spatch transformation to replace boolean uses of !hashcmp() to
newly introduced oideq() is added, and applied, to regain
performance lost due to support of multiple hash algorithms.
* Fix a bug in which the same path could be registered under multiple
worktree entries if the path was missing (for instance, was removed
manually). Also, as a convenience, expand the number of cases in
which --force is applicable.
* Split Documentation/config.txt for easier maintenance.
(merge 6014363f0b nd/config-split later to maint).
* Test helper binaries clean-up.
(merge c9a1f4161f nd/test-tool later to maint).
* Various tests have been updated to make it easier to swap the
hash function used for object identification.
(merge ae0c89d41b bc/hash-independent-tests later to maint).
* Update fsck.skipList implementation and documentation.
(merge 371a655074 ab/fsck-skiplist later to maint).
* An alias that expands to another alias has so far been forbidden,
but now it is allowed to create such an alias.
* Various test scripts have been updated for style and also correct
handling of exit status of various commands.
* "gc --auto" ended up calling exit(-1) upon error, which has been
corrected to use exit(1). Also the error reporting behaviour when
daemonized has been updated to exit with zero status when stopping
due to a previously discovered error (which implies there is no
point running gc to improve the situation); we used to exit with
failure in such a case.
* Various codepaths in the core-ish part learned to work on an
arbitrary in-core index structure, not necessarily the default
instance "the_index".
(merge b3c7eef9b0 nd/the-index later to maint).
* Code clean-up in the internal machinery used by "git status" and
"git commit --dry-run".
(merge 73ba5d78b4 ss/wt-status-committable later to maint).
* Some environment variables that control the runtime options of Git
used during tests are getting renamed for consistency.
(merge 4231d1ba99 bp/rename-test-env-var later to maint).
* A pair of new extensions to the index file have been introduced.
They allow the index file to be read in parallel for performance.
* The oidset API was built on top of the oidmap API which in turn is
on the hashmap API. Replace the implementation to build on top of
the khash API and gain performance.
* Over some transports, fetching objects with an exact commit object
name can be done without first seeing the ref advertisements. The
code has been optimized to exploit this.
* In a partial clone that will lazily be hydrated from the
originating repository, we generally want to avoid "does this
object exist (locally)?" on objects that we deliberately omitted
when we created the clone. The cache-tree codepath (which is used
to write a tree object out of the index) however insisted that the
object exists, even for paths that are outside of the partial
checkout area. The code has been updated to avoid such a check.
* To help developers, an EditorConfig file that attempts to follow
the project convention has been added.
(merge b548d698a0 bc/editorconfig later to maint).
* The result of coverage test can be combined with "git blame" to
check the test coverage of code introduced recently with a new
'coverage-diff' tool (in contrib/).
(merge 783faedd65 ds/coverage-diff later to maint).
* An experiment to fuzz test a few areas, hopefully we can gain more
coverage to various areas.
* More codepaths are moving away from hardcoded hash sizes.
* The way the Windows port figures out the current directory has been
improved.
* The way DLLs are loaded on the Windows port has been improved.
* Some tests have been reorganized and renamed; "ls t/" now gives a
better overview of what is tested for these scripts than before.
* "git rebase" and "git rebase -i" have been reimplemented in C.
* Windows port learned to use nano-second resolution file timestamps.
* The overly large Documentation/config.txt file have been split into
million little pieces. This potentially allows each individual piece
to be included into the manual page of the command it affects more easily.
* Replace three string-list instances used as look-up tables in "git
fetch" with hashmaps.
* Unify code to read the author-script used in "git am" and the
commands that use the sequencer machinery, e.g. "git rebase -i".
* In preparation to the day when we can deprecate and remove the
"rebase -p", make sure we can skip and later remove tests for
it.
* The history traversal used to implement the tag-following has been
optimized by introducing a new helper.
* The helper function to refresh the cached stat information in the
in-core index has learned to perform the lstat() part of the
operation in parallel on multi-core platforms.
* The code to traverse objects for reachability, used to decide what
objects are unreferenced and expendable, have been taught to also
consider per-worktree refs of other worktrees as starting points to
prevent data loss.
* "git add" needs to internally run "diff-files" equivalent, and the
codepath learned the same optimization as "diff-files" has to run
lstat(2) in parallel to find which paths have been updated in the
working tree.
* The procedure to install dependencies before testing at Travis CI
is getting revamped for both simplicity and flexibility, taking
advantage of the recent move to the vm-based environment.
* The support for format-patch (and send-email) by the command-line
completion script (in contrib/) has been simplified a bit.
* The revision walker machinery learned to take advantage of the
commit generation numbers stored in the commit-graph file.
* The codebase has been cleaned up to reduce "#ifndef NO_PTHREADS".
* The way -lcurl library gets linked has been simplified by taking
advantage of the fact that we can just ask curl-config command how.
* Various functions have been audited for "-Wunused-parameter" warnings
and bugs in them got fixed.
* A sanity check for start-up sequence has been added in the config
API codepath.
* The build procedure to link for fuzzing test has been made
customizable with a new Makefile variable.
* The way "git rebase" parses and forwards the command line options
meant for underlying "git am" has been revamped, which fixed for
options with parameters that were not passed correctly.
* Our testing framework uses a special i18n "poisoned localization"
feature to find messages that ought to stay constant but are
incorrectly marked to be translated. This feature has been made
into a runtime option (it used to be a compile-time option).
* "git push" used to check ambiguities between object-names and
refnames while processing the list of refs' old and new values,
which was unnecessary (as it knew that it is feeding raw object
names). This has been optimized out.
* The xcurl_off_t() helper function is used to cast size_t to
curl_off_t, but some compilers gave warnings against the code to
ensure the casting is done without wraparound, when size_t is
narrower than curl_off_t. This warning has been squelched.
* Code preparation to replace ulong vars with size_t vars where
appropriate continues.
* The "test installed Git" mode of our test suite has been updated to
work better.
* A coding convention around the Coccinelle semantic patches to have
two classes to ease code migration process has been proposed and
its support has been added to the Makefile.
* The "container" mode of TravisCI is going away. Our .travis.yml
file is getting prepared for the transition.
(merge 32ee384be8 ss/travis-ci-force-vm-mode later to maint).
* Our test scripts can now take the '-V' option as a synonym for the
'--verbose-log' option.
(merge a5f52c6dab sg/test-verbose-log later to maint).
Fixes since v2.19
-----------------
* "git interpret-trailers" and its underlying machinery had a buggy
code that attempted to ignore patch text after commit log message,
which triggered in various codepaths that will always get the log
message alone and never get such an input.
(merge 66e83d9b41 jk/trailer-fixes later to maint).
* Malformed or crafted data in packstream can make our code attempt
to read or write past the allocated buffer and abort, instead of
reporting an error, which has been fixed.
* "git rebase -i" did not clear the state files correctly when a run
of "squash/fixup" is aborted and then the user manually amended the
commit instead, which has been corrected.
(merge 10d2f35436 js/rebase-i-autosquash-fix later to maint).
* When fsmonitor is in use, after operation on submodules updates
.gitmodules, we lost track of the fact that we did so and relied on
stale fsmonitor data.
(merge 43f1180814 bp/mv-submodules-with-fsmonitor later to maint).
* Fix for a long-standing bug that leaves the index file corrupt when
it shrinks during a partial commit.
(merge 6c003d6ffb jk/reopen-tempfile-truncate later to maint).
* Further fix for O_APPEND emulation on Windows
(merge eeaf7ddac7 js/mingw-o-append later to maint).
* A corner case bugfix in "git rerere" code.
(merge ad2bf0d9b4 en/rerere-multi-stage-1-fix later to maint).
* "git add ':(attr:foo)'" is not supported and is supposed to be
rejected while the command line arguments are parsed, but we fail
to reject such a command line upfront.
(merge 84d938b732 nd/attr-pathspec-fix later to maint).
* Recent update broke the reachability algorithm when refs (e.g.
tags) that point at objects that are not commit were involved,
which has been fixed.
* "git rebase" etc. in Git 2.19 fails to abort when given an empty
commit log message as result of editing, which has been corrected.
(merge a3ec9eaf38 en/sequencer-empty-edit-result-aborts later to maint).
* The code to backfill objects in lazily cloned repository did not
work correctly, which has been corrected.
(merge e68302011c jt/lazy-object-fetch-fix later to maint).
* Update error messages given by "git remote" and make them consistent.
(merge 5025425dff ms/remote-error-message-update later to maint).
* "git update-ref" learned to make both "--no-deref" and "--stdin"
work at the same time.
(merge d345e9fbe7 en/update-ref-no-deref-stdin later to maint).
* Recently added "range-diff" had a corner-case bug to cause it
segfault, which has been corrected.
(merge e467a90c7a tg/range-diff-corner-case-fix later to maint).
* The recently introduced commit-graph auxiliary data is incompatible
with mechanisms such as replace & grafts that "breaks" immutable
nature of the object reference relationship. Disable optimizations
based on its use (and updating existing commit-graph) when these
incompatible features are in use in the repository.
(merge 829a321569 ds/commit-graph-with-grafts later to maint).
* The mailmap file update.
(merge 255eb03edf jn/mailmap-update later to maint).
* The code in "git status" sometimes hit an assertion failure. This
was caused by a structure that was reused without cleaning the data
used for the first run, which has been corrected.
(merge 3e73cc62c0 en/status-multiple-renames-to-the-same-target-fix later to maint).
* "git fetch $repo $object" in a partial clone did not correctly
fetch the asked-for object that is referenced by an object in
promisor packfile, which has been fixed.
* A corner-case bugfix.
(merge c5cbb27cb5 sm/show-superproject-while-conflicted later to maint).
* Various fixes to "diff --color-moved-ws".
* A partial clone that is configured to lazily fetch missing objects
will on-demand issue a "git fetch" request to the originating
repository to fill not-yet-obtained objects. The request has been
optimized for requesting a tree object (and not the leaf blob
objects contained in it) by telling the originating repository that
no blobs are needed.
(merge 4c7f9567ea jt/non-blob-lazy-fetch later to maint).
* The codepath to support the experimental split-index mode had
remaining "racily clean" issues fixed.
(merge 4c490f3d32 sg/split-index-racefix later to maint).
* "git log --graph" showing an octopus merge sometimes miscounted the
number of display columns it is consuming to show the merge and its
parent commits, which has been corrected.
(merge 04005834ed np/log-graph-octopus-fix later to maint).
* "git range-diff" did not work well when the compared ranges had
changes in submodules and the "--submodule=log" was used.
* The implementation of run_command() API on the UNIX platforms had a
bug that caused a command not on $PATH to be found in the current
directory.
(merge f67b980771 jk/run-command-notdot later to maint).
* A mutex used in "git pack-objects" were not correctly initialized
and this caused "git repack" to dump core on Windows.
(merge 34204c8166 js/pack-objects-mutex-init-fix later to maint).
* Under certain circumstances, "git diff D:/a/b/c D:/a/b/d" on
Windows would strip initial parts from the paths because they
were not recognized as absolute, which has been corrected.
(merge ffd04e92e2 js/diff-notice-has-drive-prefix later to maint).
* The receive.denyCurrentBranch=updateInstead codepath kicked in even
when the push should have been rejected due to other reasons, such
as it does not fast-forward or the update-hook rejects it, which
has been corrected.
(merge b072a25fad jc/receive-deny-current-branch-fix later to maint).
* The logic to determine the archive type "git archive" uses did not
correctly kick in for "git archive --remote", which has been
corrected.
* "git repack" in a shallow clone did not correctly update the
shallow points in the repository, leading to a repository that
does not pass fsck.
(merge 5dcfbf564c js/shallow-and-fetch-prune later to maint).
* Some codepaths failed to form a proper URL when .gitmodules record
the URL to a submodule repository as relative to the repository of
superproject, which has been corrected.
(merge e0a862fdaf sb/submodule-url-to-absolute later to maint).
* "git fetch" over protocol v2 into a shallow repository failed to
fetch full history behind a new tip of history that was diverged
before the cut-off point of the history that was previously fetched
shallowly.
* The command line completion machinery (in contrib/) has been
updated to allow the completion script to tweak the list of options
that are reported by the parse-options machinery correctly.
(merge 276b49ff34 nd/completion-negation later to maint).
* Operations on promisor objects make sense in the context of only a
small subset of the commands that internally use the revisions
machinery, but the "--exclude-promisor-objects" option were taken
and led to nonsense results by commands like "log", to which it
didn't make much sense. This has been corrected.
(merge 669b1d2aae md/exclude-promisor-objects-fix later to maint).
* A regression in Git 2.12 era made "git fsck" fall into an infinite
loop while processing truncated loose objects.
(merge 18ad13e5b2 jk/detect-truncated-zlib-input later to maint).
* "git ls-remote $there foo" was broken by recent update for the
protocol v2 and stopped showing refs that match 'foo' that are not
refs/{heads,tags}/foo, which has been fixed.
(merge 6a139cdd74 jk/proto-v2-ref-prefix-fix later to maint).
* Additional comment on a tricky piece of code to help developers.
(merge 0afbe3e806 jk/stream-pack-non-delta-clarification later to maint).
* A couple of tests used to leave the repository in a state that is
deliberately corrupt, which have been corrected.
(merge aa984dbe5e ab/pack-tests-cleanup later to maint).
* The submodule support has been updated to read from the blob at
HEAD:.gitmodules when the .gitmodules file is missing from the
working tree.
(merge 2b1257e463 ao/submodule-wo-gitmodules-checked-out later to maint).
* "git fetch" was a bit loose in parsing responses from the other side
when talking over the protocol v2.
* "git rev-parse --exclude=* --branches --branches" (i.e. first
saying "add only things that do not match '*' out of all branches"
and then adding all branches, without any exclusion this time)
worked as expected, but "--exclude=* --all --all" did not work the
same way, which has been fixed.
(merge 5221048092 ag/rev-parse-all-exclude-fix later to maint).
* "git send-email --transfer-encoding=..." in recent versions of Git
sometimes produced an empty "Content-Transfer-Encoding:" header,
which has been corrected.
(merge 3c88e46f1a al/send-email-auto-cte-fixup later to maint).
* The interface into "xdiff" library used to discover the offset and
size of a generated patch hunk by first formatting it into the
textual hunk header "@@ -n,m +k,l @@" and then parsing the numbers
out. A new interface has been introduced to allow callers a more
direct access to them.
(merge 5eade0746e jk/xdiff-interface later to maint).
* Pathspec matching against a tree object were buggy when negative
pathspec elements were involved, which has been fixed.
(merge b7845cebc0 nd/tree-walk-path-exclusion later to maint).
* "git merge" and "git pull" that merges into an unborn branch used
to completely ignore "--verify-signatures", which has been
corrected.
(merge 01a31f3bca jk/verify-sig-merge-into-void later to maint).
* "git rebase --autostash" did not correctly re-attach the HEAD at times.
* "rev-parse --exclude=<pattern> --branches=<pattern>" etc. did not
quite work, which has been corrected.
(merge 9ab9b5df0e ra/rev-parse-exclude-glob later to maint).
* When editing a patch in a "git add -i" session, a hunk could be
made to no-op. The "git apply" program used to reject a patch with
such a no-op hunk to catch user mistakes, but it is now updated to
explicitly allow a no-op hunk in an edited patch.
(merge 22cb3835b9 js/apply-recount-allow-noop later to maint).
* The URL to an MSDN page in a comment has been updated.
(merge 2ef2ae2917 js/mingw-msdn-url later to maint).
* "git ls-remote --sort=<thing>" can feed an object that is not yet
available into the comparison machinery and segfault, which has
been corrected to check such a request upfront and reject it.
* When "git bundle" aborts due to an empty commit ranges
(i.e. resulting in an empty pack), it left a file descriptor to an
lockfile open, which resulted in leftover lockfile on Windows where
you cannot remove a file with an open file descriptor. This has
been corrected.
(merge 2c8ee1f53c jk/close-duped-fd-before-unlock-for-bundle later to maint).
* "git format-patch --stat=<width>" can be used to specify the width
used by the diffstat (shown in the cover letter).
(merge 284aeb7e60 nd/format-patch-cover-letter-stat-width later to maint).
* The way .git/index and .git/sharedindex* files were initially
created gave these files different perm bits until they were
adjusted for shared repository settings. This was made consistent.
(merge c9d6c78870 cc/shared-index-permbits later to maint).
* "git rebase --stat" to transplant a piece of history onto a totally
unrelated history were not working before and silently showed wrong
result. With the recent reimplementation in C, it started to instead
die with an error message, as the original logic was not prepared
to cope with this case. This has now been fixed.
* The advice message to tell the user to migrate an existing graft
file to the replace system when a graft file was read was shown
even when "git replace --convert-graft-file" command, which is the
way the message suggests to use, was running, which made little
sense.
(merge 8821e90a09 ab/replace-graft-with-replace-advice later to maint).
* "git diff --raw" lost ellipses to adjust the output columns for
some time now, but the documentation still showed them.
* Code cleanup, docfix, build fix, etc.

Git 2.19 Release Notes
Updates since v2.18
-------------------
UI, Workflows & Features
* "git diff" compares the index and the working tree. For paths
added with intent-to-add bit, the command shows the full contents
of them as added, but the paths themselves were not marked as new
files. They are now shown as new by default.
"git apply" learned the "--intent-to-add" option so that an
otherwise working-tree-only application of a patch will add new
paths to the index marked with the "intent-to-add" bit.
* "git grep" learned the "--column" option that gives not just the
line number but the column number of the hit.
* The "-l" option in "git branch -l" is an unfortunate short-hand for
"--create-reflog", but many users, both old and new, somehow expect
it to be something else, perhaps "--list". This step warns when "-l"
is used as a short-hand for "--create-reflog" and warns about the
future repurposing of the it when it is used.
* The userdiff pattern for .php has been updated.
* The content-transfer-encoding of the message "git send-email" sends
out by default was 8bit, which can cause trouble when there is an
overlong line to bust RFC 5322/2822 limit. A new option 'auto' to
automatically switch to quoted-printable when there is such a line
in the payload has been introduced and is made the default.
* "git checkout" and "git worktree add" learned to honor
checkout.defaultRemote when auto-vivifying a local branch out of a
remote tracking branch in a repository with multiple remotes that
have tracking branches that share the same names.
(merge 8d7b558bae ab/checkout-default-remote later to maint).
* "git grep" learned the "--only-matching" option.
* "git rebase --rebase-merges" mode now handles octopus merges as
well.
* Add a server-side knob to skip commits in exponential/fibbonacci
stride in an attempt to cover wider swath of history with a smaller
number of iterations, potentially accepting a larger packfile
transfer, instead of going back one commit a time during common
ancestor discovery during the "git fetch" transaction.
(merge 42cc7485a2 jt/fetch-negotiator-skipping later to maint).
* A new configuration variable core.usereplacerefs has been added,
primarily to help server installations that want to ignore the
replace mechanism altogether.
* Teach "git tag -s" etc. a few configuration variables (gpg.format
that can be set to "openpgp" or "x509", and gpg.<format>.program
that is used to specify what program to use to deal with the format)
to allow x.509 certs with CMS via "gpgsm" to be used instead of
openpgp via "gnupg".
* Many more strings are prepared for l10n.
* "git p4 submit" learns to ask its own pre-submit hook if it should
continue with submitting.
* The test performed at the receiving end of "git push" to prevent
bad objects from entering repository can be customized via
receive.fsck.* configuration variables; we now have gained a
counterpart to do the same on the "git fetch" side, with
fetch.fsck.* configuration variables.
* "git pull --rebase=interactive" learned "i" as a short-hand for
"interactive".
* "git instaweb" has been adjusted to run better with newer Apache on
RedHat based distros.
* "git range-diff" is a reimplementation of "git tbdiff" that lets us
compare individual patches in two iterations of a topic.
* The sideband code learned to optionally paint selected keywords at
the beginning of incoming lines on the receiving end.
* "git branch --list" learned to take the default sort order from the
'branch.sort' configuration variable, just like "git tag --list"
pays attention to 'tag.sort'.
* "git worktree" command learned "--quiet" option to make it less
verbose.
Performance, Internal Implementation, Development Support etc.
* The bulk of "git submodule foreach" has been rewritten in C.
* The in-core "commit" object had an all-purpose "void *util" field,
which was tricky to use especially in library-ish part of the
code. All of the existing uses of the field has been migrated to a
more dedicated "commit-slab" mechanism and the field is eliminated.
* A less often used command "git show-index" has been modernized.
(merge fb3010c31f jk/show-index later to maint).
* The conversion to pass "the_repository" and then "a_repository"
throughout the object access API continues.
* Continuing with the idea to programatically enumerate various
pieces of data required for command line completion, teach the
codebase to report the list of configuration variables
subcommands care about to help complete them.
* Separate "rebase -p" codepath out of "rebase -i" implementation to
slim down the latter and make it easier to manage.
* Make refspec parsing codepath more robust.
* Some flaky tests have been fixed.
* Continuing with the idea to programmatically enumerate various
pieces of data required for command line completion, the codebase
has been taught to enumerate options prefixed with "--no-" to
negate them.
* Build and test procedure for netrc credential helper (in contrib/)
has been updated.
* Remove unused function definitions and declarations from ewah
bitmap subsystem.
* Code preparation to make "git p4" closer to be usable with Python 3.
* Tighten the API to make it harder to misuse in-tree .gitmodules
file, even though it shares the same syntax with configuration
files, to read random configuration items from it.
* "git fast-import" has been updated to avoid attempting to create
delta against a zero-byte-long string, which is pointless.
* The codebase has been updated to compile cleanly with -pedantic
option.
(merge 2b647a05d7 bb/pedantic later to maint).
* The character display width table has been updated to match the
latest Unicode standard.
(merge 570951eea2 bb/unicode-11-width later to maint).
* test-lint now looks for broken use of "VAR=VAL shell_func" in test
scripts.
* Conversion from uchar[40] to struct object_id continues.
* Recent "security fix" to pay attention to contents of ".gitmodules"
while accepting "git push" was a bit overly strict than necessary,
which has been adjusted.
* "git fsck" learns to make sure the optional commit-graph file is in
a sane state.
* "git diff --color-moved" feature has further been tweaked.
* Code restructuring and a small fix to transport protocol v2 during
fetching.
* Parsing of -L[<N>][,[<M>]] parameters "git blame" and "git log"
take has been tweaked.
* lookup_commit_reference() and friends have been updated to find
in-core object for a specific in-core repository instance.
* Various glitches in the heuristics of merge-recursive strategy have
been documented in new tests.
* "git fetch" learned a new option "--negotiation-tip" to limit the
set of commits it tells the other end as "have", to reduce wasted
bandwidth and cycles, which would be helpful when the receiving
repository has a lot of refs that have little to do with the
history at the remote it is fetching from.
* For a large tree, the index needs to hold many cache entries
allocated on heap. These cache entries are now allocated out of a
dedicated memory pool to amortize malloc(3) overhead.
* Tests to cover various conflicting cases have been added for
merge-recursive.
* Tests to cover conflict cases that involve submodules have been
added for merge-recursive.
* Look for broken "&&" chains that are hidden in subshell, many of
which have been found and corrected.
* The singleton commit-graph in-core instance is made per in-core
repository instance.
* "make DEVELOPER=1 DEVOPTS=pedantic" allows developers to compile
with -pedantic option, which may catch more problematic program
constructs and potential bugs.
* Preparatory code to later add json output for telemetry data has
been added.
* Update the way we use Coccinelle to find out-of-style code that
need to be modernised.
* It is too easy to misuse system API functions such as strcat();
these selected functions are now forbidden in this codebase and
will cause a compilation failure.
* Add a script (in contrib/) to help users of VSCode work better with
our codebase.
* The Travis CI scripts were taught to ship back the test data from
failed tests.
(merge aea8879a6a sg/travis-retrieve-trash-upon-failure later to maint).
* The parse-options machinery learned to refrain from enclosing
placeholder string inside a "<bra" and "ket>" pair automatically
without PARSE_OPT_LITERAL_ARGHELP. Existing help text for option
arguments that are not formatted correctly have been identified and
fixed.
(merge 5f0df44cd7 rs/parse-opt-lithelp later to maint).
* Noiseword "extern" has been removed from function decls in the
header files.
* A few atoms like %(objecttype) and %(objectsize) in the format
specifier of "for-each-ref --format=<format>" can be filled without
getting the full contents of the object, but just with the object
header. These cases have been optimized by calling
oid_object_info() API (instead of reading and inspecting the data).
* The end result of documentation update has been made to be
inspected more easily to help developers.
* The API to iterate over all objects learned to optionally list
objects in the order they appear in packfiles, which helps locality
of access if the caller accesses these objects while as objects are
enumerated.
* Improve built-in facility to catch broken &&-chain in the tests.
* The more library-ish parts of the codebase learned to work on the
in-core index-state instance that is passed in by their callers,
instead of always working on the singleton "the_index" instance.
* A test prerequisite defined by various test scripts with slightly
different semantics has been consolidated into a single copy and
made into a lazily defined one.
(merge 6ec633059a wc/make-funnynames-shared-lazy-prereq later to maint).
* After a partial clone, repeated fetches from promisor remote would
have accumulated many packfiles marked with .promisor bit without
getting them coalesced into fewer packfiles, hurting performance.
"git repack" now learned to repack them.
* Partially revert the support for multiple hash functions to regain
hash comparison performance; we'd think of a way to do this better
in the next cycle.
* "git help --config" (which is used in command line completion)
missed the configuration variables not described in the main
config.txt file but are described in another file that is included
by it, which has been corrected.
* The test linter code has learned that the end of here-doc mark
"EOF" can be quoted in a double-quote pair, not just in a
single-quote pair.

|
2.18.0:
UI, Workflows & Features
* Rename detection logic that is used in "merge" and "cherry-pick" has
learned to guess when all of x/a, x/b and x/c have moved to z/a,
z/b and z/c, it is likely that x/d added in the meantime would also
want to move to z/d by taking the hint that the entire directory
'x' moved to 'z'. A bug causing dirty files involved in a rename
to be overwritten during merge has also been fixed as part of this
work. Incidentally, this also avoids updating a file in the
working tree after a (non-trivial) merge whose result matches what
our side originally had.
* "git filter-branch" learned to use a different exit code to allow
the callers to tell the case where there was no new commits to
rewrite from other error cases.
* When built with more recent cURL, GIT_SSL_VERSION can now specify
"tlsv1.3" as its value.
* "git gui" learned that "~/.ssh/id_ecdsa.pub" and
"~/.ssh/id_ed25519.pub" are also possible SSH key files.
(merge 2e2f0288ef bb/git-gui-ssh-key-files later to maint).
* "git gui" performs commit upon CTRL/CMD+ENTER but the
CTRL/CMD+KP_ENTER (i.e. enter key on the numpad) did not have the
same key binding. It now does.
(merge 28a1d94a06 bp/git-gui-bind-kp-enter later to maint).
* "git gui" has been taught to work with old versions of tk (like
8.5.7) that do not support "ttk::style theme use" as a way to query
the current theme.
(merge 4891961105 cb/git-gui-ttk-style later to maint).
* "git rebase" has learned to honor "--signoff" option when using
backends other than "am" (but not "--preserve-merges").
* "git branch --list" during an interrupted "rebase -i" now lets
users distinguish the case where a detached HEAD is being rebased
and a normal branch is being rebased.
* "git mergetools" learned talking to guiffy.
* The scripts in contrib/emacs/ have outlived their usefulness and
have been replaced with a stub that errors out and tells the user
there are replacements.
* The new "working-tree-encoding" attribute can ask Git to convert the
contents to the specified encoding when checking out to the working
tree (and the other way around when checking in).
* The "git config" command uses separate options e.g. "--int",
"--bool", etc. to specify what type the caller wants the value to
be interpreted as. A new "--type=<typename>" option has been
introduced, which would make it cleaner to define new types.
* "git config --get" learned the "--default" option, to help the
calling script. Building on top of the above changes, the
"git config" learns "--type=color" type. Taken together, you can
do things like "git config --get foo.color --default blue" and get
the ANSI color sequence for the color given to foo.color variable,
or "blue" if the variable does not exist.
* "git ls-remote" learned an option to allow sorting its output based
on the refnames being shown.
* The command line completion (in contrib/) has been taught that "git
stash save" has been deprecated ("git stash push" is the preferred
spelling in the new world) and does not offer it as a possible
completion candidate when "git stash push" can be.
* "git gc --prune=nonsense" spent long time repacking and then
silently failed when underlying "git prune --expire=nonsense"
failed to parse its command line. This has been corrected.
* Error messages from "git push" can be painted for more visibility.
* "git http-fetch" (deprecated) had an optional and experimental
"feature" to fetch only commits and/or trees, which nobody used.
This has been removed.
* The functionality of "$GIT_DIR/info/grafts" has been superseded by
the "refs/replace/" mechanism for some time now, but the internal
code had support for it in many places, which has been cleaned up
in order to drop support of the "grafts" mechanism.
* "git worktree add" learned to check out an existing branch.
* "git --no-pager cmd" did not have short-and-sweet single letter
option. Now it does as "-P".
(merge 7213c28818 js/no-pager-shorthand later to maint).
* "git rebase" learned "--rebase-merges" to transplant the whole
topology of commit graph elsewhere.
* "git status" learned to pay attention to UI related diff
configuration variables such as diff.renames.
* The command line completion mechanism (in contrib/) learned to load
custom completion file for "git $command" where $command is a
custom "git-$command" that the end user has on the $PATH when using
newer version of bash-completion.
* "git send-email" can sometimes offer confirmation dialog "Send this
email?" with choices 'Yes', 'No', 'Quit', and 'All'. A new action
'Edit' has been added to this dialog's choice.
* With merge.renames configuration set to false, the recursive merge
strategy can be told not to spend cycles trying to find renamed
paths and merge them accordingly.
* "git status" learned to honor a new status.renames configuration to
skip rename detection, which could be useful for those who want to
do so without disabling the default rename detection done by the
"git diff" command.
* Command line completion (in contrib/) learned to complete pathnames
for various commands better.
* "git blame" learns to unhighlight uninteresting metadata from the
originating commit on lines that are the same as the previous one,
and also paint lines in different colors depending on the age of
the commit.
* Transfer protocol v2 learned to support the partial clone.
* When a short hexadecimal string is used to name an object but there
are multiple objects that share the string as the prefix of their
names, the code lists these ambiguous candidates in a help message.
These object names are now sorted according to their types for
easier eyeballing.
* "git fetch $there $refspec" that talks over protocol v2 can take
advantage of server-side ref filtering; the code has been extended
so that this mechanism triggers also when fetching with configured
refspec.
* Our HTTP client code used to advertise that we accept gzip encoding
from the other side; instead, just let cURL library to advertise
and negotiate the best one.
* "git p4" learned to "unshelve" shelved commit from P4.
(merge 123f631761 ld/p4-unshelve later to maint).

Git 2.17:
UI, Workflows & Features
* "diff" family of commands learned "--find-object=<object-id>" option
to limit the findings to changes that involve the named object.
* "git format-patch" learned to give 72-cols to diffstat, which is
consistent with other line length limits the subcommand uses for
its output meant for e-mails.
* The log from "git daemon" can be redirected with a new option; one
relevant use case is to send the log to standard error (instead of
syslog) when running it from inetd.
* "git rebase" learned to take "--allow-empty-message" option.
* "git am" has learned the "--quit" option, in addition to the
existing "--abort" option; having the pair mirrors a few other
commands like "rebase" and "cherry-pick".
* "git worktree add" learned to run the post-checkout hook, just like
"git clone" runs it upon the initial checkout.
* "git tag" learned an explicit "--edit" option that allows the
message given via "-m" and "-F" to be further edited.
* "git fetch --prune-tags" may be used as a handy short-hand for
getting rid of stale tags that are locally held.
* The new "--show-current-patch" option gives an end-user facing way
to get the diff being applied when "git rebase" (and "git am")
stops with a conflict.
* "git add -p" used to offer "/" (look for a matching hunk) as a
choice, even there was only one hunk, which has been corrected.
Also the single-key help is now given only for keys that are
enabled (e.g. help for '/' won't be shown when there is only one
hunk).
* Since Git 1.7.9, "git merge" defaulted to --no-ff (i.e. even when
the side branch being merged is a descendant of the current commit,
create a merge commit instead of fast-forwarding) when merging a
tag object. This was appropriate default for integrators who pull
signed tags from their downstream contributors, but caused an
unnecessary merges when used by downstream contributors who
habitually "catch up" their topic branches with tagged releases
from the upstream. Update "git merge" to default to --no-ff only
when merging a tag object that does *not* sit at its usual place in
refs/tags/ hierarchy, and allow fast-forwarding otherwise, to
mitigate the problem.
* "git status" can spend a lot of cycles to compute the relation
between the current branch and its upstream, which can now be
disabled with "--no-ahead-behind" option.
* "git diff" and friends learned funcname patterns for Go language
source files.
* "git send-email" learned "--reply-to=<address>" option.
* Funcname pattern used for C# now recognizes "async" keyword.
* In a way similar to how "git tag" learned to honor the pager
setting only in the list mode, "git config" learned to ignore the
pager setting when it is used for setting values (i.e. when the
purpose of the operation is not to "show").
Performance, Internal Implementation, Development Support etc.
* More perf tests for threaded grep
* "perf" test output can be sent to codespeed server.
* The build procedure for perl/ part has been greatly simplified by
weaning ourselves off of MakeMaker.
* Perl 5.8 or greater has been required since Git 1.7.4 released in
2010, but we continued to assume some core modules may not exist and
used a conditional "eval { require <<module>> }"; we no longer do
this. Some platforms (Fedora/RedHat/CentOS, for example) ship Perl
without all core modules by default (e.g. Digest::MD5, File::Temp,
File::Spec, Net::Domain, Net::SMTP). Users on such platforms may
need to install these additional modules.
* As a convenience, we install copies of Perl modules we require which
are not part of the core Perl distribution (e.g. Error and
Mail::Address). Users and packagers whose operating system provides
these modules can set NO_PERL_CPAN_FALLBACKS to avoid installing the
bundled modules.
* In preparation for implementing narrow/partial clone, the machinery
for checking object connectivity used by gc and fsck has been
taught that a missing object is OK when it is referenced by a
packfile specially marked as coming from trusted repository that
promises to make them available on-demand and lazily.
* The machinery to clone & fetch, which in turn involves packing and
unpacking objects, has been told how to omit certain objects using
the filtering mechanism introduced by another topic. It now knows
to mark the resulting pack as a promisor pack to tolerate missing
objects, laying foundation for "narrow" clones.
* The first step to getting rid of mru API and using the
doubly-linked list API directly instead.
* Retire mru API as it does not give enough abstraction over
underlying list API to be worth it.
* Rewrite two more "git submodule" subcommands in C.
* The tracing machinery learned to report tweaking of environment
variables as well.
* Update Coccinelle rules to catch and optimize strbuf_addf(&buf, "%s", str)
* Prevent "clang-format" from breaking line after function return type.
* The sequencer infrastructure is shared across "git cherry-pick",
"git rebase -i", etc., and has always spawned "git commit" when it
needs to create a commit. It has been taught to do so internally,
when able, by reusing the codepath "git commit" itself uses, which
gives performance boost for a few tens of percents in some sample
scenarios.
* Push the submodule version of collision-detecting SHA-1 hash
implementation a bit harder on builders.
* Avoid mmapping small files while using packed refs (especially ones
with zero size, which would cause later munmap() to fail).
* Conversion from uchar[20] to struct object_id continues.
* More tests for wildmatch functions.
* The code to binary search starting from a fan-out table (which is
how the packfile is indexed with object names) has been refactored
into a reusable helper.
* We now avoid using identifiers that clash with C++ keywords. Even
though it is not a goal to compile Git with C++ compilers, changes
like this help use of code analysis tools that targets C++ on our
codebase.
* The executable is now built in 'script' phase in Travis CI integration,
to follow the established practice, rather than during 'before_script'
phase. This allows the CI categorize the failures better ('failed'
is project's fault, 'errored' is build environment's).
* Writing out the index file when the only thing that changed in it
is the untracked cache information is often wasteful, and this has
been optimized out.
* Various pieces of Perl code we have have been cleaned up.
* Internal API clean-up to allow write_locked_index() optionally skip
writing the in-core index when it is not modified.
|
|
======================
Backward compatibility notes and other notable changes.
* Use of an empty string as a pathspec element that is used for
'everything matches' is still warned and Git asks users to use a
more explicit '.' for that instead. The hope is that existing
users will not mind this change, and eventually the warning can be
turned into a hard error, upgrading the deprecation into removal of
this (mis)feature. That is not scheduled to happen in the upcoming
release (yet).
* Git now avoids blindly falling back to ".git" when the setup
sequence said we are _not_ in Git repository. A corner case that
happens to work right now may be broken by a call to die("BUG").
We've tried hard to locate such cases and fixed them, but there
might still be cases that need to be addressed--bug reports are
greatly appreciated.
* The experiment to improve the hunk-boundary selection of textual
diff output has finished, and the "indent heuristics" has now
become the default.
* Git can now be built with PCRE v2 instead of v1 of the PCRE
library. Replace USE_LIBPCRE=YesPlease with USE_LIBPCRE2=YesPlease
in existing build scripts to build against the new version. As the
upstream PCRE maintainer has abandoned v1 maintenance for all but
the most critical bug fixes, use of v2 is recommended.
Updates since v2.13
-------------------
UI, Workflows & Features
* The colors in which "git status --short --branch" showed the names
of the current branch and its remote-tracking branch are now
configurable.
* "git clone" learned the "--no-tags" option not to fetch all tags
initially, and also set up the tagopt not to follow any tags in
subsequent fetches.
* "git archive --format=zip" learned to use zip64 extension when
necessary to go beyond the 4GB limit.
* "git reset" learned "--recurse-submodules" option.
* "git diff --submodule=diff" now recurses into nested submodules.
* "git repack" learned to accept the --threads=<n> option and pass it
to pack-objects.
* "git send-email" learned to run sendemail-validate hook to inspect
and reject a message before sending it out.
* There is no good reason why "git fetch $there $sha1" should fail
when the $sha1 names an object at the tip of an advertised ref,
even when the other side hasn't enabled allowTipSHA1InWant.
* The "[includeIf "gitdir:$dir"] path=..." mechanism introduced in
2.13.0 would canonicalize the path of the gitdir being matched,
and did not match e.g. "gitdir:~/work/*" against a repo in
"~/work/main" if "~/work" was a symlink to "/mnt/storage/work".
Now we match both the resolved canonical path and what "pwd" would
show. The include will happen if either one matches.
* The "indent" heuristics is now the default in "diff". The
diff.indentHeuristic configuration variable can be set to "false"
for those who do not want it.
* Many commands learned to pay attention to submodule.recurse
configuration.
* The convention for a command line is to follow "git cmdname
--options" with revisions followed by an optional "--"
disambiguator and then finally pathspecs. When "--" is not there,
we make sure early ones are all interpretable as revs (and do not
look like paths) and later ones are the other way around. A
pathspec with "magic" (e.g. ":/p/a/t/h" that matches p/a/t/h from
the top-level of the working tree, no matter what subdirectory you
are working from) are conservatively judged as "not a path", which
required disambiguation more often. The command line parser
learned to say "it's a pathspec" a bit more often when the syntax
looks like so.
* Update "perl-compatible regular expression" support to enable JIT
and also allow linking with the newer PCRE v2 library.
* "filter-branch" learned a pseudo filter "--setup" that can be used
to define common functions/variables that can be used by other
filters.
* Using "git add d/i/r" when d/i/r is the top of the working tree of
a separate repository would create a gitlink in the index, which
would appear as a not-quite-initialized submodule to others. We
learned to give warnings when this happens.
* "git status" learned to optionally give how many stash entries there
are in its output.
* "git status" has long shown essentially the same message as "git
commit"; the message it gives while preparing for the root commit,
i.e. "Initial commit", was hard to understand for some new users.
Now it says "No commits yet" to stress more on the current status
(rather than the commit the user is preparing for, which is more in
line with the focus of "git commit").
* "git send-email" now has --batch-size and --relogin-delay options
which can be used to overcome limitations on SMTP servers that
restrict on how many of e-mails can be sent in a single session.
* An old message shown in the commit log template was removed, as it
has outlived its usefulness.
* "git pull --rebase --recurse-submodules" learns to rebase the
branch in the submodules to an updated base.
* "git log" learned -P as a synonym for --perl-regexp, "git grep"
already had such a synonym.
* "git log" didn't understand --regexp-ignore-case when combined with
--perl-regexp. This has been fixed.
Performance, Internal Implementation, Development Support etc.
* The default packed-git limit value has been raised on larger
platforms to save "git fetch" from a (recoverable) failure while
"gc" is running in parallel.
* Code to update the cache-tree has been tightened so that we won't
accidentally write out any 0{40} entry in the tree object.
* Attempt to allow us notice "fishy" situation where we fail to
remove the temporary directory used during the test.
* Travis CI gained a task to format the documentation with both
AsciiDoc and AsciiDoctor.
* Some platforms have ulong that is smaller than time_t, and our
historical use of ulong for timestamp would mean they cannot
represent some timestamp that the platform allows. Invent a
separate and dedicated timestamp_t (so that we can distingiuish
timestamps and a vanilla ulongs, which along is already a good
move), and then declare uintmax_t is the type to be used as the
timestamp_t.
* We can trigger Windows auto-build tester (credits: Dscho &
Microsoft) from our existing Travis CI tester now.
* Conversion from uchar[20] to struct object_id continues.
* Simplify parse_pathspec() codepath and stop it from looking at the
default in-core index.
* Add perf-test for wildmatch.
* Code from "conversion using external process" codepath has been
extracted to a separate sub-process.[ch] module.
* When "git checkout", "git merge", etc. manipulates the in-core
index, various pieces of information in the index extensions are
discarded from the original state, as it is usually not the case
that they are kept up-to-date and in-sync with the operation on the
main index. The untracked cache extension is copied across these
operations now, which would speed up "git status" (as long as the
cache is properly invalidated).
* The internal implementation of "git grep" has seen some clean-up.
* Update the C style recommendation for notes for translators, as
recent versions of gettext tools can work with our style of
multi-line comments.
* The implementation of "ref" API around the "packed refs" have been
cleaned up, in preparation for further changes.
* The internal logic used in "git blame" has been libified to make it
easier to use by cgit.
* Our code often opens a path to an optional file, to work on its
contents when we can successfully open it. We can ignore a failure
to open if such an optional file does not exist, but we do want to
report a failure in opening for other reasons (e.g. we got an I/O
error, or the file is there, but we lack the permission to open).
The exact errors we need to ignore are ENOENT (obviously) and
ENOTDIR (less obvious). Instead of repeating comparison of errno
with these two constants, introduce a helper function to do so.
* We often try to open a file for reading whose existence is
optional, and silently ignore errors from open/fopen; report such
errors if they are not due to missing files.
* When an existing repository is used for t/perf testing, we first
create bit-for-bit copy of it, which may grab a transient state of
the repository and freeze it into the repository used for testing,
which then may cause Git operations to fail. Single out "the index
being locked" case and forcibly drop the lock from the copy.
* Three instances of the same helper function have been consolidated
to one.
* "fast-import" uses a default pack chain depth that is consistent
with other parts of the system.
* A new test to show the interaction between the pattern [^a-z]
(which matches '/') and a slash in a path has been added. The
pattern should not match the slash with "pathmatch", but should
with "wildmatch".
* The 'diff-highlight' program (in contrib/) has been restructured
for easier reuse by an external project 'diff-so-fancy'.
* A common pattern to free a piece of memory and assign NULL to the
pointer that used to point at it has been replaced with a new
FREE_AND_NULL() macro.
* Traditionally, the default die() routine had a code to prevent it
from getting called multiple times, which interacted badly when a
threaded program used it (one downside is that the real error may
be hidden and instead the only error message given to the user may
end up being "die recursion detected", which is not very useful).
* Introduce a "repository" object to eventually make it easier to
work in multiple repositories (the primary focus is to work with
the superproject and its submodules) in a single process.
* Optimize "what are the object names already taken in an alternate
object database?" query that is used to derive the length of prefix
an object name is uniquely abbreviated to.
* The hashmap API has been updated so that data to customize the
behaviour of the comparison function can be specified at the time a
hashmap is initialized.
* The "collision detecting" SHA-1 implementation shipped with 2.13 is
now integrated into git.git as a submodule (the first submodule to
ship with git.git). Clone git.git with --recurse-submodules to get
it. For now a non-submodule copy of the same code is also shipped
as part of the tree.
* A recent update made it easier to use "-fsanitize=" option while
compiling but supported only one sanitize option. Allow more than
one to be combined, joined with a comma, like "make SANITIZE=foo,bar".
* Use "p4 -G" to make "p4 changes" output more Python-friendly
to parse.
* We started using "%" PRItime, imitating "%" PRIuMAX and friends, as
a way to format the internal timestamp value, but this does not
play well with gettext(1) i18n framework, and causes "make pot"
that is run by the l10n coordinator to create a broken po/git.pot
file. This is a possible workaround for that problem.
* It turns out that Cygwin also needs the fopen() wrapper that
returns failure when a directory is opened for reading.

======================
Backward compatibility notes.
* Use of an empty string that is used for 'everything matches' is
still warned and Git asks users to use a more explicit '.' for that
instead. The hope is that existing users will not mind this
change, and eventually the warning can be turned into a hard error,
upgrading the deprecation into removal of this (mis)feature. That
is not scheduled to happen in the upcoming release (yet).
* The historical argument order "git merge <msg> HEAD <commit>..."
has been deprecated for quite some time, and will be removed in a
future release.
* An ancient script "git relink" has been removed.
Updates since v2.11
-------------------
UI, Workflows & Features
* Various updates to "git p4".
* "git p4" didn't interact with the internal of .git directory
correctly in the modern "git-worktree"-enabled world.
* "git branch --list" and friends learned "--ignore-case" option to
optionally sort branches and tags case insensitively.
* In addition to %(subject), %(body), "log --pretty=format:..."
learned a new placeholder %(trailers).
* "git rebase" learned "--quit" option, which allows a user to
remove the metadata left by an earlier "git rebase" that was
manually aborted without using "git rebase --abort".
* "git clone --reference $there --recurse-submodules $super" has been
taught to guess repositories usable as references for submodules of
$super that are embedded in $there while making a clone of the
superproject borrow objects from $there; extend the mechanism to
also allow submodules of these submodules to borrow repositories
embedded in these clones of the submodules embedded in the clone of
the superproject.
* Porcelain scripts written in Perl are getting internationalized.
* "git merge --continue" has been added as a synonym to "git commit"
to conclude a merge that has stopped due to conflicts.
* Finer-grained control of what protocols are allowed for transports
during clone/fetch/push have been enabled via a new configuration
mechanism.
* "git shortlog" learned "--committer" option to group commits by
committer, instead of author.
* GitLFS integration with "git p4" has been updated.
* The isatty() emulation for Windows has been updated to eradicate
the previous hack that depended on internals of (older) MSVC
runtime.
* Some platforms no longer understand "latin-1" that is still seen in
the wild in e-mail headers; replace them with "iso-8859-1" that is
more widely known when conversion fails from/to it.
* "git grep" has been taught to optionally recurse into submodules.
* "git rm" used to refuse to remove a submodule when it has its own
git repository embedded in its working tree. It learned to move
the repository away to $GIT_DIR/modules/ of the superproject
instead, and allow the submodule to be deleted (as long as there
will be no loss of local modifications, that is).
* A recent updates to "git p4" was not usable for older p4 but it
could be made to work with minimum changes. Do so.
* "git diff" learned diff.interHunkContext configuration variable
that gives the default value for its --inter-hunk-context option.
* The prereleaseSuffix feature of version comparison that is used in
"git tag -l" did not correctly when two or more prereleases for the
same release were present (e.g. when 2.0, 2.0-beta1, and 2.0-beta2
are there and the code needs to compare 2.0-beta1 and 2.0-beta2).
* "git submodule push" learned "--recurse-submodules=only option to
push submodules out without pushing the top-level superproject.
* "git tag" and "git verify-tag" learned to put GPG verification
status in their "--format=<placeholders>" output format.
* An ancient repository conversion tool left in contrib/ has been
removed.
* "git show-ref HEAD" used with "--verify" because the user is not
interested in seeing refs/remotes/origin/HEAD, and used with
"--head" because the user does not want HEAD to be filtered out,
i.e. "git show-ref --head --verify HEAD", did not work as expected.
* "git submodule add" used to be confused and refused to add a
locally created repository; users can now use "--force" option
to add them.
(merge 619acfc78c sb/submodule-add-force later to maint).
* Some people feel the default set of colors used by "git log --graph"
rather limiting. A mechanism to customize the set of colors has
been introduced.
* "git read-tree" and its underlying unpack_trees() machinery learned
to report problematic paths prefixed with the --super-prefix option.
* When a submodule "A", which has another submodule "B" nested within
it, is "absorbed" into the top-level superproject, the inner
submodule "B" used to be left in a strange state. The logic to
adjust the .git pointers in these submodules has been corrected.
* The user can specify a custom update method that is run when
"submodule update" updates an already checked out submodule. This
was ignored when checking the submodule out for the first time and
we instead always just checked out the commit that is bound to the
path in the superproject's index.
* The command line completion (in contrib/) learned that
"git diff --submodule=" can take "diff" as a recently added option.
* The "core.logAllRefUpdates" that used to be boolean has been
enhanced to take 'always' as well, to record ref updates to refs
other than the ones that are expected to be updated (i.e. branches,
remote-tracking branches and notes).
* Comes with more command line completion (in contrib/) for recently
introduced options.
|
|
UI, Workflows & Features
* The bash completion script (in contrib/) learned a few options that
"git revert" takes.
* Whitespace breakages in deleted and context lines can also be
painted in the output of "git diff" and friends with the new
--ws-error-highlight option.
* List of commands shown by "git help" are grouped along the workflow
elements to help early learners.
* "git p4" now detects the filetype (e.g. binary) correctly even when
the files are opened exclusively.
* git p4 attempts to better handle branches in Perforce.
* "git p4" learned "--changes-block-size <n>" to read the changes in
chunks from Perforce, instead of making one call to "p4 changes"
that may trigger "too many rows scanned" error from Perforce.
* More workaround for Perforce's row number limit in "git p4".
* Unlike "$EDITOR" and "$GIT_EDITOR" that can hold the path to the
command and initial options (e.g. "/path/to/emacs -nw"), 'git p4'
did not let the shell interpolate the contents of the environment
variable that name the editor "$P4EDITOR" (and "$EDITOR", too).
This release makes it in line with the rest of Git, as well as with
Perforce.
* A new short-hand <branch>@{push} denotes the remote-tracking branch
that tracks the branch at the remote the <branch> would be pushed
to.
* "git show-branch --topics HEAD" (with no other arguments) did not
do anything interesting. Instead, contrast the given revision
against all the local branches by default.
* A replacement for contrib/workdir/git-new-workdir that does not
rely on symbolic links and make sharing of objects and refs safer
by making the borrowee and borrowers aware of each other.
Consider this as still an experimental feature; its UI is still
likely to change.
* Tweak the sample "store" backend of the credential helper to honor
XDG configuration file locations when specified.
* A heuristic we use to catch mistyped paths on the command line
"git <cmd> <revs> <pathspec>" is to make sure that all the non-rev
parameters in the later part of the command line are names of the
files in the working tree, but that means "git grep $str -- \*.c"
must always be disambiguated with "--", because nobody sane will
create a file whose name literally is asterisk-dot-see. Loosen the
heuristic to declare that with a wildcard string the user likely
meant to give us a pathspec.
* "git merge FETCH_HEAD" learned that the previous "git fetch" could
be to create an Octopus merge, i.e. recording multiple branches
that are not marked as "not-for-merge"; this allows us to lose an
old style invocation "git merge <msg> HEAD $commits..." in the
implementation of "git pull" script; the old style syntax can now
be deprecated (but not removed yet).
* Filter scripts were run with SIGPIPE disabled on the Git side,
expecting that they may not read what Git feeds them to filter.
We however treated a filter that does not read its input fully
before exiting as an error. We no longer do and ignore EPIPE
when writing to feed the filter scripts.
This changes semantics, but arguably in a good way. If a filter
can produce its output without fully consuming its input using
whatever magic, we now let it do so, instead of diagnosing it
as a programming error.
* Instead of dying immediately upon failing to obtain a lock, the
locking (of refs etc) retries after a short while with backoff.
* Introduce http.<url>.SSLCipherList configuration variable to tweak
the list of cipher suite to be used with libcURL when talking with
https:// sites.
* "git subtree" script (in contrib/) used "echo -n" to produce
progress messages in a non-portable way.
* "git subtree" script (in contrib/) does not have --squash option
when pushing, but the documentation and help text pretended as if
it did.
* The Git subcommand completion (in contrib/) no longer lists credential
helpers among candidates; they are not something the end user would
invoke interactively.
* The index file can be taught with "update-index --untracked-cache"
to optionally remember already seen untracked files, in order to
speed up "git status" in a working tree with tons of cruft.
* "git mergetool" learned to drive WinMerge as a backend.
* "git upload-pack" that serves "git fetch" can be told to serve
commits that are not at the tip of any ref, as long as they are
reachable from a ref, with uploadpack.allowReachableSHA1InWant
configuration variable.
|
|
Ports
* Building on older MacOS X systems automatically sets
the necessary NO_APPLE_COMMON_CRYPTO build-time option.
* Building with NO_PTHREADS has been resurrected.
* Compilation options have been updated a bit to better support the
z/OS port.
UI, Workflows & Features
* "git archive" learned to filter what gets archived with a pathspec.
* "git config --edit --global" starts from a skeletal per-user
configuration file contents, instead of a total blank, when the
user does not already have any global config. This immediately
reduces the need to later ask "Have you forgotten to set
core.user?", and we can add more to the template as we gain
more experience.
* "git stash list -p" used to be almost always a no-op because each
stash entry is represented as a merge commit. It learned to show
the difference between the base commit version and the working tree
version, which is in line with what "git stash show" gives.
* Sometimes users want to report a bug they experience on their
repository, but they are not at liberty to share the contents of
the repository. "fast-export" was taught an "--anonymize" option
to replace blob contents, names of people, paths and log
messages with bland and simple strings to help them.
* "git difftool" learned an option to stop feeding paths to the
diff backend when it exits with a non-zero status.
* "git grep" learned to paint (or not paint) partial matches on
context lines when showing "grep -C<num>" output in color.
* "log --date=iso" uses a slight variant of the ISO 8601 format that is
more human readable. A new "--date=iso-strict" option gives
datetime output that conforms more strictly.
* The logic "git prune" uses is more resilient against various corner
cases.
* A broken reimplementation of Git could write an invalid index that
records both stage 0 and higher-stage entries for the same path.
We now notice and reject such an index, as there is no sensible
fallback (we do not know if the broken tool wanted to resolve and
forgot to remove the higher-stage entries, or if it wanted to unresolve
and forgot to remove the stage 0 entry).
* The temporary files "git mergetool" uses are renamed to avoid too
many dots in them (e.g. a temporary file for "hello.c" used to be
named e.g. "hello.BASE.4321.c" but now uses underscore instead,
e.g. "hello_BASE_4321.c", to allow us to have multiple variants).
* The temporary files "git mergetool" uses can be placed in a newly
created temporary directory, instead of the current directory, by
setting the mergetool.writeToTemp configuration variable.
* "git mergetool" understands "--tool bc" now, as version 4 of
BeyondCompare can be driven the same way as its version 3 and it
feels awkward to say "--tool bc3" to run version 4.
* The "pre-receive" and "post-receive" hooks are no longer required
to consume their input fully (not following this requirement used
to result in intermittent errors in "git push").
* The pretty-format specifier "%d", which expands to " (tagname)"
for a tagged commit, gained a cousin "%D" that just gives the
"tagname" without frills.
* "git push" learned "--signed" push, that allows a push (i.e.
request to update the refs on the other side to point at a new
history, together with the transmission of necessary objects) to be
signed, so that it can be verified and audited, using the GPG
signature of the person who pushed, that the tips of branches at a
public repository really point the commits the pusher wanted to,
without having to "trust" the server.
* "git interpret-trailers" is a new filter to programmatically edit
the tail end of the commit log messages, e.g. "Signed-off-by:".
* "git help everyday" shows the "Everyday Git in 20 commands or so"
document, whose contents have been updated to match more modern
Git practice.
* On the "git svn" front, work progresses to reduce memory consumption and
to improve handling of mergeinfo.
|
|
Backward compatibility notes
----------------------------
* The default value we give to the environment variable LESS has been
changed from "FRSX" to "FRX", losing "S" (chop long lines instead
of wrapping). Existing users who prefer not to see line-wrapped
output may want to set
$ git config core.pager "less -S"
to restore the traditional behaviour. It is expected that people
find output from most subcommands easier to read with the new
default, except for "blame" which tends to produce really long
lines. To override the new default only for "git blame", you can
do this:
$ git config pager.blame "less -S"
* A few disused directories in contrib/ have been retired.
Updates since v2.0
------------------
UI, Workflows & Features
* Since the very beginning of Git, we gave the LESS environment a
default value "FRSX" when we spawn "less" as the pager. "S" (chop
long lines instead of wrapping) has been removed from this default
set of options, because it is more or less a personal taste thing,
as opposed to the others that have good justifications (i.e. "R" is
very much justified because many kinds of output we produce are
colored and "FX" is justified because output we produce is often
shorter than a page).
* The logic and data used to compute the display width needed for
UTF-8 strings have been updated to match Unicode 7.0 better.
* HTTP-based transports learned to better propagate the error messages from
the webserver to the client coming over the HTTP transport.
* The completion script for bash (in contrib/) has been updated to
better handle aliases that define a complex sequence of commands.
* The "core.preloadindex" configuration variable is enabled by default,
allowing modern platforms to take advantage of their
multiple cores.
* "git clone" applies the "if cloning from a local disk, physically
copy the repository using hardlinks, unless otherwise told not to with
--no-local" optimization when the url.*.insteadOf mechanism rewrites a
remote-repository "git clone $URL" into a
clone from a local disk.
* "git commit --date=<date>" option learned more
timestamp formats, including "--date=now".
* The `core.commentChar` configuration variable is used to specify a
custom comment character (other than the default "#") for
the commit message editor. This can be set to `auto` to attempt to
choose a different character that does not conflict with any that
already starts a line in the message being edited, for cases like
"git commit --amend".
* "git format-patch" learned --signature-file=<file> to add the contents
of a file as a signature to the mail message it produces.
* "git grep" learned the grep.fullname configuration variable to force
"--full-name" to be the default. This may cause regressions for
scripted users who do not expect this new behaviour.
* "git imap-send" learned to ask the credential helper for auth
material.
* "git log" and friends now understand the value "auto" for the
"log.decorate" configuration variable to enable the "--decorate"
option automatically when the output is sent to tty.
* "git merge" without an argument, even when there is an upstream
defined for the current branch, refused to run until
merge.defaultToUpstream is set to true. Flip the default of that
configuration variable to true.
* "git mergetool" learned to drive the vimdiff3 backend.
* mergetool.prompt used to default to 'true', always asking "do you
really want to run the tool on this path?". The default has been
changed to 'false'. However, the prompt will still appear if
mergetool used its autodetection system to guess which tool to use.
Users who explicitly specify or configure a tool will no longer see
the prompt by default.
Strictly speaking, this is a backward incompatible change and
users need to explicitly set the variable to 'true' if they want
to be prompted to confirm running the tool on each path.
* "git replace" learned the "--edit" subcommand to create a
replacement by editing an existing object.
* "git replace" learned a "--graft" option to rewrite the parents of a
commit.
* "git send-email" learned "--to-cover" and "--cc-cover" options, to
tell it to copy To: and Cc: headers found in the first input file
when emitting later input files.
* "git svn" learned to cope with malformed timestamps with only one
digit in the hour part, e.g. 2014-01-07T5:01:02.048176Z, emitted
by some broken subversion server implementations.
* "git tag" when editing the tag message shows the name of the tag
being edited as a comment in the editor.
* "git tag" learned to pay attention to "tag.sort" configuration, to
be used as the default sort order when no --sort=<value> option
is given.
* A new "git verify-commit" command, to check GPG signatures in signed
commits, in a way similar to "git verify-tag" is used to check
signed tags, was added.
|
|
Foreign interfaces, subsystems and ports.
* The HTTP transport, when talking GSS-Negotiate, uses "100
Continue" response to avoid having to rewind and resend a large
payload, which may not be always doable.
* Various bugfixes to remote-bzr and remote-hg (in contrib/).
* The build procedure is aware of MirBSD now.
* Various "git p4", "git svn" and "gitk" updates.
UI, Workflows & Features
* Fetching from a shallowly-cloned repository used to be forbidden,
primarily because the codepaths involved were not carefully vetted
and we did not bother supporting such usage. This release attempts
to allow object transfer out of a shallowly-cloned repository in a
more controlled way (i.e. the receiver becomes a shallow repository
with a truncated history).
* Just like we give a reasonable default for "less" via the LESS
environment variable, we now specify a reasonable default for "lv"
via the "LV" environment variable when spawning the pager.
* Two-level configuration variable names in "branch.*" and "remote.*"
hierarchies, whose variables are predominantly three-level, were
not completed by hitting a <TAB> in bash and zsh completions.
* Fetching a 'frotz' branch with "git fetch", while a 'frotz/nitfol'
remote-tracking branch from an earlier fetch was still there, would
error out, primarily because the command was not told that it is
allowed to lose any information on our side. "git fetch --prune"
now can be used to remove 'frotz/nitfol' to make room for fetching and
storing the 'frotz' remote-tracking branch.
* "diff.orderfile=<file>" configuration variable can be used to
pretend as if the "-O<file>" option were given from the command
line of "git diff", etc.
* The negative pathspec syntax allows "git log -- . ':!dir'" to tell
us "I am interested in everything but 'dir' directory".
* "git difftool" shows how many different paths there are in total,
and how many of them have been shown so far, to indicate progress.
* "git push origin master" used to push our 'master' branch to update
the 'master' branch at the 'origin' repository. This has been
enhanced to use the same ref mapping "git push origin" would use to
determine what ref at the 'origin' to be updated with our 'master'.
For example, with this configuration
[remote "origin"]
push = refs/heads/*:refs/review/*
that would cause "git push origin" to push out our local branches
to corresponding refs under refs/review/ hierarchy at 'origin',
"git push origin master" would update 'refs/review/master' over
there. Alternatively, if push.default is set to 'upstream' and our
'master' is set to integrate with 'topic' from the 'origin' branch,
running "git push origin" while on our 'master' would update their
'topic' branch, and running "git push origin master" while on any
of our branches does the same.
* "gitweb" learned to treat ref hierarchies other than refs/heads as
if they are additional branch namespaces (e.g. refs/changes/ in
Gerrit).
* "git for-each-ref --format=..." learned a few formatting directives;
e.g. "%(color:red)%(HEAD)%(color:reset) %(refname:short) %(subject)".
* The command string given to "git submodule foreach" is passed
directly to the shell, without being eval'ed. This is a backward
incompatible change that may break existing users.
* "git log" and friends learned the "--exclude=<glob>" option, to
allow people to say "list history of all branches except those that
match this pattern" with "git log --exclude='*/*' --branches".
* "git rev-parse --parseopt" learned a new "--stuck-long" option to
help scripts parse options with an optional parameter.
* The "--tags" option to "git fetch" no longer tells the command to
fetch _only_ the tags. It instead fetches tags _in addition to_
what are fetched by the same command line without the option.
