bzr 1.6 2008-08-25
------------------
Finally, the long awaited bzr 1.6 has been released. This release includes
new features like Stacked Branches, improved weave merge, and an updated
server protocol (now on v3) which will allow for better cross version
compatibility. With this release we have deprecated Knit format
repositories, and recommend that users upgrade them, we will continue to
support reading and writing them for the forseeable future, but we will
not be tuning them for performance as pack repositories have proven to be
better at scaling. This will also be the first release to bundle
TortoiseBzr in the standalone Windows installer.
bzr 1.6rc5 2008-08-19
---------------------
BUG FIXES:
* Disable automatic detection of stacking based on a containing
directory of the target. It interacted badly with push, and needs a
bit more work to get the edges polished before it should happen
automatically. (John Arbash Meinel, #259275)
bzr 1.6rc4 2008-08-18
---------------------
BUG FIXES:
* Fix a regression in knit => pack fetching. We had a logic
inversion, causing the fetch to insert fulltexts in random order,
rather than preserving deltas. (John Arbash Meinel, #256757)
bzr 1.6rc3 2008-08-14
---------------------
CHANGES:
* Disable reading ``.bzrrules`` as a per-branch rule preferences
file. The feature was not quite ready for a full release.
(Robert Collins)
IMPROVEMENTS:
* Update the windows installer to bundle TortoiseBzr and ``qbzr``
into the standalone installer. This will be the first official
windows release that installs Tortoise by default.
(Mark Hammond)
BUG FIXES:
* Fix a regression in ``bzr+http`` support. There was a missing
function (``_read_line``) that needed to be carried over from
``bzr+ssh`` support. (Andrew Bennetts)
* ``GraphIndex`` objects will internally read an entire index if more
than 1/20th of their keyspace is requested in a single operation.
This largely mitigates a performance regression in ``bzr log FILE``
and completely corrects the performance regression in ``bzr log``.
The regression was caused by removing an accomodation which had been
supporting the index format in use. A newer index format is in
development which is substantially faster. (Robert Collins)
bzr 1.6rc2 2008-08-13
---------------------
This release candidate has a few minor bug fixes, and some regression
fixes for Windows.
BUG FIXES:
* ``bzr upgrade`` on remote branches accessed via bzr:// and
bzr+ssh:// now works. (Andrew Bennetts)
* Change the ``get_format_description()`` strings for
``RepositoryFormatKnitPack5`` et al to be single line messages.
(Aaron Bentley)
* Fix for a regression on Win32 where we would try to call
``os.listdir()`` on a file and not catch the exception properly.
(Windows raises a different exception.) This would manifest in
places like ``bzr rm file`` or ``bzr switch``.
(Mark Hammond, John Arbash Meinel)
* ``Inventory.copy()`` was failing to set the revision property for
the root entry. (Jelmer Vernooij)
* sftp transport: added missing ``FileExists`` case to
``_translate_io_exception`` (Christophe Troestler, #123475)
* The help for ``bzr ignored`` now suggests ``bzr ls --ignored`` for
scripting use. (Robert Collins, #3834)
* The default ``annotate`` logic will now always assign the
last-modified value of a line to one of the revisions that modified
it, rather than a merge revision. This would happen when both sides
claimed to have modified the line resulting in the same text. The
choice is arbitrary but stable, so merges in different directions
will get the same results. (John Arbash Meinel, #232188)
bzr 1.6rc1 2008-08-06
---------------------
This release candidate for bzr 1.6 solidifies the new branch stacking
feature. Bazaar now recommends that users upgrade all knit repositories,
because later formats are much faster. However, we plan to continue read/write and
upgrade support for knit repostories for the forseeable future. Several
other bugs and performance issues were fixed.
CHANGES:
* Knit format repositories are deprecated and bzr will now emit
warnings whenever it encounters one. Use ``bzr upgrade`` to upgrade
knit repositories to pack format. (Andrew Bennetts)
IMPROVEMENTS:
* ``bzr check`` can now be told which elements at a location it should
check. (Daniel Watkins)
* Commit now supports ``--exclude`` (or ``-x``) to exclude some files
from the commit. (Robert Collins, #3117)
* Fetching data between repositories that have the same model but no
optimised fetcher will not reserialise all the revisions, increasing
performance. (Robert Collins, John Arbash Meinel)
* Give a more specific error when target branch is not reachable.
(James Westby)
* Implemented a custom ``walkdirs_utf8`` implementation for win32.
This uses a pyrex extension to get direct access to the
``FindFirstFileW`` style apis, rather than using ``listdir`` +
``lstat``. Shows a very strong improvement in commands like
``status`` and ``diff`` which have to iterate the working tree.
Anywhere from 2x-6x faster depending on the size of the tree (bigger
trees, bigger benefit.) (John Arbash Meinel)
* New registry for log properties handles and the method in
LongLogFormatter to display the custom properties returned by the
registered handlers. (Guillermo Gonzalez, #162469)
BUG FIXES:
* Add more tests that stacking does not create deltas spanning
physical repository boundaries.
(Martin Pool, #252428)
* Better message about incompatible repositories.
(Martin Pool, #206258)
* ``bzr branch --stacked`` ensures the destination branch format can
support stacking, even if the origin does not.
(Martin Pool)
* ``bzr export`` no longer exports ``.bzrrules``.
(Ian Clatworthy)
* ``bzr serve --directory=/`` now correctly allows the whole
filesystem to be accessed on Windows, not just the root of the drive
that Python is running from.
(Adrian Wilkins, #240910)
* Deleting directories by hand before running ``bzr rm`` will not
cause subsequent errors in ``bzr st`` and ``bzr commit``.
(Robert Collins, #150438)
* Fix a test case that was failing if encoding wasn't UTF-8.
(John Arbash Meinel, #247585)
* Fix "no buffer space available" error when branching with the new
smart server protocol to or from Windows.
(Andrew Bennetts, #246180)
* Fixed problem in branching from smart server.
(#249256, Michael Hudson, Martin Pool)
* Handle a file turning in to a directory in TreeTransform.
(James Westby, #248448)
API CHANGES:
* ``MutableTree.commit`` has an extra optional keywork parameter
``exclude`` that will be unconditionally supplied by the command
line UI - plugins that add tree formats may need an update.
(Robert Collins)
* The API minimum version for plugin compatibility has been raised to
1.6 - there are significant changes throughout the code base.
(Robert Collins)
* The generic fetch code now uses three attributes on Repository objects
to control fetch. The streams requested are controlled via :
``_fetch_order`` and ``_fetch_uses_deltas``. Setting these
appropriately allows different repository implementations to recieve
data in their optimial form. If the ``_fetch_reconcile`` is set then
a reconcile operation is triggered at the end of the fetch.
(Robert Collins)
* The ``put_on_disk`` and ``get_tar_item`` methods in
``InventoryEntry`` were deprecated. (Ian Clatworthy)
* ``Repository.is_shared`` doesn't take a read lock. It didn't
need one in the first place (nobody cached the value, and
``RemoteRepository`` wasn't taking one either). This saves a round
trip when probing Pack repositories, as they read the ``pack-names``
file when locked. And during probe, locking the repo isn't very
useful. (John Arbash Meinel)
INTERNALS:
* ``bzrlib.branchbuilder.BranchBuilder`` is now much more capable of
putting together a real history without having to create a full
WorkingTree. It is recommended that tests that are not directly
testing the WorkingTree use BranchBuilder instead. See
``BranchBuilder.build_snapshot`` or
``TestCaseWithMemoryTree.make_branch_builder``. (John Arbash Meinel)
* ``bzrlib.builtins.internal_tree_files`` broken into two giving a new
helper ``safe_relpath_files`` - used by the new ``exclude``
parameter to commit. (Robert Collins)
* Make it easier to introduce new WorkingTree formats.
(Ian Clatworthy)
* The code for exporting trees was refactored not to use the
deprecated ``InventoryEntry`` methods. (Ian Clatworthy)
* RuleSearchers return () instead of [] now when there are no matches.
(Ian Clatworthy)
bzr 1.6beta3 2008-07-17
-----------------------
This release adds a new 'stacked branches' feature allowing branches to
share storage without being in the same repository or on the same machine.
(See the user guide for more details.) It also adds a new hook, improved
weaves, aliases for related locations, faster bzr+ssh push, and several
bug fixes.
FEATURES:
* New ``pre_change_branch_tip`` hook that is called before the
branch tip is moved, while the branch is write-locked. See the User
Reference for signature details. (Andrew Bennetts)
* Rule-based preferences can now be defined for selected files in
selected branches, allowing commands and plugins to provide
custom behaviour for files matching defined patterns.
See ``Rule-based preferences`` (part of ``Configuring Bazaar``)
in the User Guide and ``bzr help rules`` for more information.
(Ian Clatworthy)
* Sites may suggest a branch to stack new branches on. (Aaron Bentley)
* Stacked branches are now supported. See ``bzr help branch`` and
``bzr help push``. Branches must be in the ``development1`` format
to stack, though the stacked-on branch can be of any format.
(Robert Collins)
IMPROVEMENTS:
* ``bzr export --format=tgz --root=NAME -`` to export a gzipped tarball
to stdout; also ``tar`` and ``tbz2``.
(Martin Pool)
* ``bzr (re)merge --weave`` will now use a standard Weave algorithm,
rather than the annotation-based merge it was using. It does so by
building up a Weave of the important texts, without needing to build
the full ancestry. (John Arbash Meinel, #238895)
* ``bzr send`` documents and better supports ``emacsclient`` (proper
escaping of mail headers and handling of the MUA Mew).
(Christophe Troestler)
* Remembered locations can be specified by aliases, e.g. :parent, :public,
:submit. (Aaron Bentley)
* The smart protocol now has improved support for setting branches'
revision info directly. This makes operations like push
faster. The new request method name is
``Branch.set_last_revision_ex``. (Andrew Bennetts)
BUG FIXES:
* Bazaar is now able to be a client to the web server of IIS 6 and 7.
The broken implementations of RFC822 in Python and RFC2046 in IIS
combined with boundary-line checking in Bazaar previously made this
impossible. (NB, IIS 5 does not suffer from this problem).
(Adrian Wilkins, #247585)
* ``bzr log --long`` with a ghost in your mainline now handles that
ghost properly. (John Arbash Meinel, #243536)
* ``check`` handles the split-up .bzr layout correctly, so no longer
requires a branch to be present.
(Daniel Watkins, #64783)
* Clearer message about how to set the PYTHONPATH if bzrlib can't be
loaded.
(Martin Pool, #205230)
* Errors about missing libraries are now shown without a traceback,
and with a suggestion to install the library. The full traceback is
still in ``.bzr.log`` and can be shown with ``-Derror``.
(Martin Pool, #240161)
* Fetch from a stacked branch copies all required data.
(Aaron Bentley, #248506)
* Handle urls such as ftp://user@host.com@www.host.com where the user
name contains an @.
(Neil Martinsen-Burrell, #228058)
* ``needs_read_lock`` and ``needs_write_lock`` now suppress an error during
``unlock`` if there was an error in the original function. This helps
most when there is a failure with a smart server action, since often the
connection closes and we cannot unlock.
(Andrew Bennetts, John Arbash Meinel, #125784)
* Obsolete hidden command ``bzr fetch`` removed.
(Martin Pool, #172870)
* Raise the correct exception when doing ``-rbefore:0`` or ``-c0``.
(John Arbash Meinel, #239933)
* You can now compare file revisions in Windows diff programs from
Cygwin Bazaar.
(Matt McClure, #209281)
* revision_history now tolerates mainline ghosts for Branch format 6.
(Aaron Bentley, #235055)
* Set locale from environment for third party libs.
(Martin von Gagern, #128496)
DOCUMENTATION:
* Added *Using stacked branches* to the User Guide.
(Ian Clatworthy)
* Updated developer documentation.
(Martin Pool)
TESTING:
* ``-Dmemory`` will cause /proc/PID/status to be catted before bzr
exits, allowing low-key analysis of peak memory use. (Robert Collins)
* ``TestCaseWithTransport.make_branch_and_tree`` tries harder to return
a tree with a ``branch`` attribute of the right format. This was
preventing some ``RemoteBranch`` tests from actually running with
``RemoteBranch`` instances. (Andrew Bennetts)
API CHANGES:
* Removed ``Repository.text_store``, ``control_store``, etc. Instead,
there are new attributes ``texts, inventories, revisions,
signatures``, each of which is a ``VersionedFiles``. See the
Repository docstring for more details.
(Robert Collins)
* ``Branch.pull`` now accepts an ``_override_hook_target`` optional
parameter. If you have a subclass of ``Branch`` that overrides
``pull`` then you should add this parameter. (Andrew Bennetts)
* ``bzrlib.check.check()`` has been deprecated in favour of the more
aptly-named ``bzrlib.check.check_branch()``.
(Daniel Watkins)
* ``Tree.print_file`` and ``Repository.print_file`` are deprecated.
These methods are bad APIs because they write directly to sys.stdout.
bzrlib does not use them internally, and there are no direct tests
for them. (Alexander Belchenko)
INTERNALS:
* ``cat`` command no longer uses ``Tree.print_file()`` internally.
(Alexander Belchenko)
* New class method ``BzrDir.open_containing_tree_branch_or_repository``
which eases the discovery of the tree, the branch and the repository
containing a given location.
(Daniel Watkins)
* New ``versionedfile.KeyMapper`` interface to abstract out the access to
underlying .knit/.kndx etc files in repositories with partitioned
storage. (Robert Collins)
* Obsolete developer-use command ``weave-join`` has been removed.
(Robert Collins)
* ``RemoteToOtherFetcher`` and ``get_data_stream_for_search`` removed,
to support new ``VersionedFiles`` layering.
(Robert Collins)
bzr 1.6beta2 2008-06-10
-----------------------
This release contains further progress towards our 1.6 goals of shallow
repositories, and contains a fix for some user-affecting bugs in the
repository layer. Building working trees during checkout and branch is
now faster.
BUG FIXES:
* Avoid KnitCorrupt error extracting inventories from some repositories.
(The data is not corrupt; an internal check is detecting a problem
reading from the repository.)
(Martin Pool, Andrew Bennetts, Robert Collins, #234748)
* ``bzr status`` was breaking if you merged the same revision twice.
(John Arbash Meinel, #235407)
* Fix infinite loop consuming 100% CPU when a connection is lost while
reading a response body via the smart protocol v1 or v2.
(Andrew Bennetts)
* Inserting a bundle which changes the contents of a file with no trailing
end of line, causing a knit snapshot in a 'knits' repository will no longer
cause KnitCorrupt. (Robert Collins)
* ``RemoteBranch.pull`` needs to return the ``self._real_branch``'s
pull result. It was instead just returning None, which breaks ``bzr
pull``. (John Arbash Meinel, #238149)
* Sanitize branch nick before using it as an attachment filename in
``bzr send``. (Luká Lalinský, #210218)
* Squash ``inv_entry.symlink_target`` to a plain string when
generating DirState details. This prevents from getting a
``UnicodeError`` when you have symlinks and non-ascii filenames.
(John Arbash Meinel, #135320)
IMPROVEMENTS:
* Added the 'alias' command to set/unset and display aliases. (Tim Penhey)
* ``added``, ``modified``, and ``unknowns`` behaviour made consistent (all three
now quote paths where required). Added ``--null`` option to ``added`` and
``modified`` (for null-separated unknowns, use ``ls --unknown --null``)
(Adrian Wilkins)
* Faster branching (1.09x) and lightweight checkouts (1.06x) on large trees.
(Ian Clatworthy, Aaron Bentley)
DOCUMENTATION:
* Added *Bazaar Zen* section to the User Guide. (Ian Clatworthy)
TESTING:
* Fix the test HTTPServer to be isolated from chdir calls made while it is
running, allowing it to be used in blackbox tests. (Robert Collins)
API CHANGES:
* ``WorkingTree.set_parent_(ids/trees)`` will now filter out revisions
which are in the ancestry of other revisions. So if you merge the same
tree twice, or merge an ancestor of an existing merge, it will only
record the newest. (If you merge a descendent, it will replace its
ancestor). (John Arbash Meinel, #235407)
* ``RepositoryPolicy.__init__`` now requires stack_on and stack_on_pwd,
through the derived classes do not. (Aaron Bentley)
INTERNALS:
* ``bzrlib.bzrdir.BzrDir.sprout`` now accepts ``stacked`` to control
creating stacked branches. (Robert Collins)
* Knit record serialisation is now stricter on what it will accept, to
guard against potential internal bugs, or broken input. (Robert Collins)
bzr 1.6beta1 2008-06-02
-----------------------
Commands that work on the revision history such as push, pull, missing,
uncommit and log are now substantially faster. This release adds a
translation of some of the user documentation into Spanish. (Contributions of
other translations would be very welcome.) Bazaar 1.6beta1 adds a new network
protocol which is used by default and which allows for more efficient transfers
and future extensions.
NOTES WHEN UPGRADING:
* There is a new version of the network protocol used for bzr://, bzr+ssh://
and bzr+http:// connections. This will allow more efficient requests and
responses, and more graceful fallback when a server is too old to
recognise a request from a more recent client. Bazaar 1.6 will
interoperate with 0.16 and later versions, but servers should be upgraded
when possible. Bazaar 1.6 no longer interoperates with 0.15 and earlier via
these protocols. Use alternatives like SFTP or upgrade those servers.
(Andrew Bennetts, #83935)
CHANGES:
* Deprecation warnings will not be suppressed when running ``bzr selftest``
so that developers can see if their code is using deprecated functions.
(John Arbash Meinel)
FEATURES:
* Adding ``-Derror`` will now display a traceback when a plugin fails to
load. (James Westby)
IMPROVEMENTS:
* ``bzr branch/push/pull -r XXX`` now have a helper function for finding
the revno of the new revision (``Graph.find_distance_to_null``). This
should make something like ``bzr branch -r -100`` in a shared, no-trees
repository much snappier. (John Arbash Meinel)
* ``bzr log --short -r X..Y`` no longer needs to access the full revision
history. This makes it noticeably faster when logging the last few
revisions. (John Arbash Meinel)
* ``bzr ls`` now accepts ``-V`` as an alias for ``--versioned``.
(Jerad Cramp, #165086)
* ``bzr missing`` uses the new ``Graph.find_unique_ancestors`` and
``Graph.find_differences`` to determine missing revisions without having
to search the whole ancestry. (John Arbash Meinel, #174625)
* ``bzr uncommit`` now uses partial history access, rather than always
extracting the full revision history for a branch. This makes it
resolve the appropriate revisions much faster (in testing it drops
uncommit from 1.5s => 0.4s). It also means ``bzr log --short`` is one
step closer to not using full revision history.
(John Arbash Meinel, #172649)
BUGFIXES:
* ``bzr merge --lca`` should handle when two revisions have no common
ancestor other than NULL_REVISION. (John Arbash Meinel, #235715)
* ``bzr status`` was breaking if you merged the same revision twice.
(John Arbash Meinel, #235407)
* ``bzr push`` with both ``--overwrite`` and ``-r NNN`` options no longer
fails. (Andrew Bennetts, #234229)
* Correctly track the base URL of a smart medium when using bzr+http://
URLs, which was causing spurious "No repository present" errors with
branches in shared repositories accessed over bzr+http.
(Andrew Bennetts, #230550)
* Define ``_remote_is_at_least_1_2`` on ``SmartClientMedium`` so that all
implementations have the attribute. Fixes 'PyCurlTransport' object has no
attribute '_remote_is_at_least_1_2' attribute errors.
(Andrew Bennetts, #220806)
* Failure to delete an obsolete pack file should just give a warning
message, not a fatal error. It may for example fail if the file is still
in use by another process.
(Martin Pool)
* Fix MemoryError during large fetches over HTTP by limiting the amount of
data we try to read per ``recv`` call. The problem was observed with
Windows and a proxy, but might affect other environments as well.
(Eric Holmberg, #215426)
* Handle old merge directives correctly in Merger.from_mergeable. Stricter
get_parent_map requirements exposed a latent bug here. (Aaron Bentley)
* Issue a warning and ignore passwords declared in authentication.conf when
used for an ssh scheme (sftp or bzr+ssh).
(Vincent Ladeuil, #203186)
* Make both http implementations raise appropriate exceptions on 403
Forbidden when POSTing smart requests.
(Vincent Ladeuil, #230223)
* Properly *title* header names in http requests instead of capitalizing
them.
(Vincent Ladeuil, #229076)
* The "Unable to obtain lock" error message now also suggests using
``bzr break-lock`` to fix it. (Martin Albisetti, #139202)
* Treat an encoding of '' as ascii; this can happen when bzr is run
under vim on Mac OS X.
(Neil Martinsen-Burrell)
* ``VersionedFile.make_mpdiffs()`` was raising an exception that wasn't in
scope. (Daniel Fischer #235687)
DOCUMENTATION:
* Added directory structure and started translation of docs in spanish.
(Martin Albisetti, Lucio Albenga)
* Incorporate feedback from Jelmer Vernooij and Neil Martinsen-Burrell
on the plugin and integration chapters of the User Guide.
(Ian Clatworthy)
* More Bazaar developer documentation about packaging and release process,
and about use of Python reprs.
(Martin Pool, Martin Albisetti)
* Updated Tortise strategy document. (Mark Hammond)
TESTING:
* ``bzrlib.tests.adapt_tests`` was broken and unused - it has been fixed.
(Robert Collins)
* Fix the test HTTPServer to be isolated from chdir calls made while it is
running, allowing it to be used in blackbox tests. (Robert Collins)
* New helper function for splitting test suites
``split_suite_by_condition``. (Robert Collins)
INTERNALS:
* ``Branch.missing_revisions`` has been deprecated. Similar functionality
can be obtained using ``bzrlib.missing.find_unmerged``. The api was
fairly broken, and the function was unused, so we are getting rid of it.
(John Arbash Meinel)
API CHANGES:
* ``Branch.abspath`` is deprecated; use the Tree or Transport
instead. (Martin Pool)
* ``Branch.update_revisions`` now takes an optional ``Graph``
object. This can be used by ``update_revisions`` when it is
checking ancestry, and allows callers to prefer request to go to a
local branch. (John Arbash Meinel)
* Branch, Repository, Tree and BzrDir should expose a Transport as an
attribute if they have one, rather than having it indirectly accessible
as ``.control_files._transport``. This doesn't add a requirement
to support a Transport in cases where it was not needed before;
it just simplifies the way it is reached. (Martin Pool)
* ``bzr missing --mine-only`` will return status code 0 if you have no
new revisions, but the remote does. Similarly for ``--theirs-only``.
The new code only checks one side, so it doesn't know if the other
side has changes. This seems more accurate with the request anyway.
It also changes the output to print '[This|Other] branch is up to
date.' rather than displaying nothing. (John Arbash Meinel)
* ``LockableFiles.put_utf8``, ``put_bytes`` and ``controlfilename``
are now deprecated in favor of using Transport operations.
(Martin Pool)
* Many methods on ``VersionedFile``, ``Repository`` and in
``bzrlib.revision`` deprecated before bzrlib 1.5 have been removed.
(Robert Collins)
* ``RevisionSpec.wants_revision_history`` can be set to False for a given
``RevisionSpec``. This will disable the existing behavior of passing in
the full revision history to ``self._match_on``. Useful for specs that
don't actually need access to the full history. (John Arbash Meinel)
* The constructors of ``SmartClientMedium`` and its subclasses now require a
``base`` parameter. ``SmartClientMedium`` implementations now also need
to provide a ``remote_path_from_transport`` method. (Andrew Bennetts)
* The default permissions for creating new files and directories
should now be obtained from ``BzrDir._get_file_mode()`` and
``_get_dir_mode()``, rather than from LockableFiles. The ``_set_file_mode``
and ``_set_dir_mode`` variables on LockableFiles which were advertised
as a way for plugins to control this are no longer consulted.
(Martin Pool)
* ``VersionedFile.join`` is deprecated. This method required local
instances of both versioned file objects and was thus hostile to being
used for streaming from a smart server. The new get_record_stream and
insert_record_stream are meant to efficiently replace this method.
(Robert Collins)
* ``WorkingTree.set_parent_(ids/trees)`` will now filter out revisions
which are in the ancestry of other revisions. So if you merge the same
tree twice, or merge an ancestor of an existing merge, it will only
record the newest. (If you merge a descendent, it will replace its
ancestor). (John Arbash Meinel, #235407)
* ``WorkingTreeFormat2.stub_initialize_remote`` is now private.
(Martin Pool)
