* The log file format changed in 11gR2.
* Replication Manager sites can specify one or more possible client-to-client
peers.
* Added resource management feature in all Berkeley DB APIs to automatically
manage cursor and database handles by closing them when they are not
required, if they are not yet closed.
* Added a SQL interface to the Berkeley DB library. The interface is based on -
and a drop-in-replacement for - the SQLite API. It can be accessed via a
command line utility, a C API, or existing APIs built for SQLite.
* Added hash databases support to the DB->compact interface.
* Renamed the "db_sql" utility to "db_sql_codegen". This utility is not built
by default. To build this utility, enter --enable-sql_codegen as an argument
to configure.
* Added transactional support in db_sql_codegen utility. Specify TRANSACTIONAL
or NONTRANSACTIONAL in hint comments in SQL statement, db_sql_codegen
enable/disable transaction in generated code accordingly.
* Added the feature read-your-writes consistency that allows client application
to check, or wait for a specific transaction to be replicated from the master
before reading database.
* Added DB log verification feature, accessible via the API and a new utility.
This feature can help debugging and analysis.
* Added support for applications to assign master/client role explicitly at any
time. Replication Manager can now be configured not to initiate elections.
* more...

It is used by mk/bdb.buildlink3.mk:

MAKE_ENV+= BERKELEYDB_NAME=${BDB_LIBS:Q}

environment variable which makes (at least if GNU configure is
used the common way) that everything in the pkg gets linked against db4,
whether needed or not, which causes hidden dependencies and strange errors

This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

Berkeley DB 4.7.25 Change Log
Database or Log File On-Disk Format Changes:
1. The log file format changed in 4.7.
New Features:
1. The lock manager may now be fully partitioned, improving performance
on some multi-CPU systems. [#15880]
2. Replication groups are now architecture-neutral, supporting
connections between differing architectures (big-endian or
little-endian, independent of structure padding). [#15787] [#15840]
3. Java: A new Direct Persistence Layer adds a built-in Plain Old Java
Object (POJO)-based persistent object model, which provides support
for complex object models without compromises in performance. For an
introduction to the Direct Persistence Layer API, see Getting Started
with Data Storage. [#15936]
4. Add the DB_ENV->set_intermediate_dir_mode method to support the
creation of intermediate directories needed during recovery. [#15097]
5. The DB_ENV->failchk method can now abort transactions for threads,
which have failed while blocked on a concurrency lock. This
significantly decreases the need for database environment recovery
after thread of control failure. [#15626]
6. Replication Manager clients now can be configured to monitor the
connection to the master using heartbeat messages, in order to
promptly discover connection failures. [#15714]
7. The logging system may now be configured to pre-zero log files when
they are created, improving performance on some systems. [#15758]
Database Environment Changes:
1. Restructure aborted page allocation handling on systems without an
ftruncate system call. This enables the Berkeley DB High Availability
product on systems, which do not support ftruncate. [#15602]
2. Fix a bug where closing a database handle after aborting a transaction
which included a failed open of that handle could result in
application failure. [#15650]
3. Fix minor memory leaks when closing a private database environment.
[#15663]
4. Fix a bug leading to a panic of "unpinned page returned" if a cursor
was used for a delete multiple times and deadlocked during one of the
deletes. [#15944]
5. Optionally signal processes still running in the environment before
running recovery. [#15984]
Concurrent Data Store Changes:
None.
General Access Method Changes:
1. Fix a bug where closing a database handle after aborting a transaction
which included a failed open of that database handle could result in
application failure. [#15650]
2. Fix a bug that could cause panic in a database environment configured
with POSIX-style thread locking, if a database open failed. [#15662]
3. Fix bug in the DB->compact method which could cause a panic if a
thread was about to release a page while another thread was truncating
the database file. [#15671]
4. Fix an obscure case of interaction between a cursor scan and delete
that was prematurely returning DB_NOTFOUND. [#15785]
5. Fix a bug in the DB->compact method where if read-uncommitted was
configured, a reader reading uncommitted data my see an inconsistent
entry between when the compact method detects an error and when it
aborts the enclosing transaction. [#15856]
6. Fix a bug in the DB->compact method where a thread of control mail
fail if two threads are compacting the same section of a Recno
database. [#15856]
7. Fix a bug in DB->compact method, avoid an assertion failure when zero
pages can be freed. [#15965]
8. Fix a bug return a non-zero error when DB->truncate is called with
open cursors. [#15973]
9. Fix a bug add HANDLE_DEAD checking for DB cursors. [#15990]
10. Fix a bug to now generate errors when DB_SEQUENCE->stat is called
without first opening the sequence. [#15995]
11. Fix a bug to no longer dereference a pointer into a hash structure,
when hash functionality is disabled. [#16095]
Btree Access Method Changes:
None.
Hash Access Method Changes:
1. Fix a bug where a database store into a Hash database could
self-deadlock in a database environment configured for the Berkeley DB
Concurrent Data Store product, and with a free-threaded DB_ENV or DB
handle. [#15718]
Queue Access Method Changes:
1. Fix a bug that could cause a put or delete of a queue element to
return a DB_NOTGRANTED error, if blocked. [#15933]
Recno Access Method Changes:
1. Expose db_env_set_func_malloc, db_env_set_func_realloc, and
db_env_set_func_free through the Windows API for the DB dll. [#16045]
C-specific API Changes:
None.
Java-specific API Changes:
1. Fix a bug where enabling MVCC on a database through the Java API was
ignored. [#15644]
2. Fixed memory leak bugs in error message buffering in the Java API.
[#15843]
3. Fix a bug where Java SecondaryConfig was not setting
SecondaryMultiKeyCreator from the underlying db handle [OTN FORUM}
4. Fix a bug so that getStartupComplete will now return a boolean instead
of an int. [#16067]
5. Fix a bug in the Java API, where Berkeley DB would hang on exit when
using replication. [#16142]
Direct Persistence Layer (DPL), Bindings and Collections API:
1. A new Direct Persistence Layer adds a built-in Plain Old Java Object
(POJO)-based persistent object model, which provides support for
complex object models without compromises in performance. For an
introduction to the Direct Persistence Layer API, see Getting Started
with Data Storage. [#15936]
2. Fixed a bug in the remove method of the Iterator instances returned
by the StoredCollection.iterator method in the collections package.
This bug caused ArrayIndexOutOfBoundsException in some cases when
calling next, previous, hasNext or hasPrevious after calling remove.
(Note that this issue does not apply to StoredIterator instances
returned by the StoredCollection.storedIterator method.) This bug was
reported in this forum thread:
http://forums.oracle.com/forums/thread.jspa?messageID=2187896
[#15858]
3. Fixed a bug in the remove method of the StoredIterator instances
returned by StoredCollection.storedIterator method in the collections
package. If the sequence of methods next-remove-previous was called,
previous would sometimes return the removed record. If the sequence of
methods previous-remove-next was called, next would sometimes return
the removed record. (Note that this issue does not apply to Iterator
instances returned by the StoredCollection.iterator method.) [#15909]
4. Fixed a bug that causes a memory leak for applications where many
Environment objects are opened and closed and the CurrentTransaction
or TransactionRunner class is used. The problem was reported in this
JE Forum thread:
http://forums.oracle.com/forums/thread.jspa?messageID=1782659 [#15444]
5. Added StoredContainer.areKeyRangesAllowed method. Key ranges and the
methods in SortedMap and SortedSet such as subMap and subSet are now
explicitly disallowed for RECNO and QUEUE databases -- they are only
supported for BTREE databases. Before, using key ranges in a RECNO or
QUEUE database did not work, but was not explicitly prohibited in the
Collections API. [#15936]
Tcl-specific API Changes:
1. The Berkeley DB Tcl API does not attempt to avoid evaluating input as
Tcl commands. For this reason, it may be dangerous to pass unreviewed
user input through the Berkeley DB Tcl API, as the input may
subsequently be evaluated as a Tcl command. To minimize the
effectiveness of a Tcl injection attack, the Berkeley DB Tcl API in
the 4.7 release routine resets process' effective user and group IDs
to the real user and group IDs. [#15597]
RPC-specific Client/Server Changes:
None.
Replication Changes:
1. Fix a bug where a master failure resulted in multiple attempts to
perform a "fast election"; subsequent elections, when necessary, now
use the normal nsites value. [#15099]
2. Replication performance enhancements to speed up failover. [#15490]
3. Fix a bug where replication could self-block in a database environment
configured for in-memory logging. [#15503]
4. Fix a bug where replication would attempt to read log file version
numbers in a database configured for in-memory logging. [#15503]
5. Fix a bug where log files were not removed during client
initialization in a database configured for in-memory logging.
[#15503]
6. The 4.7 release no longer supports live replication upgrade from the
4.2 or 4.3 releases, only from the 4.4 and later releases. [#15602]
7. Fix a bug where replication could re-request missing records on every
arriving record. [#15629]
8. Change the DB_ENV->rep_set_request method to use time, not the number
of messages, when re-requesting missed messages on a replication
client. [#15629]
9. Fix a minor memory leak on the master when updating a client during
internal initialization. [#15634]
10. Fix a bug where a client error when syncing with a new replication
group master could result in an inability to ever re-join the group.
[#15648]
11. Change dbenv->rep_set_request to use time-based values instead of
counters. [#15682]
12. Fix a bug where a LOCK_NOTGRANTED error could be returned from the
DB_ENV->rep_process_message method, instead of being handled
internally by replication. [#15685]
13. Fix a bug where the Replication Manager would reject a fresh
connection from a remote site that had crashed and restarted,
displaying the message: "redundant incoming connection will be
ignored". [#15731]
14. The Replication Manager now supports dynamic negotiation of the best
available wire protocol version, on a per-connection basis. [#15783]
15. Fix a bug, which could lead to slow performance of internal
initialization under the Replication Manager, as evidenced by "queue
limit exceeded" messages in verbose replication diagnostic output.
[#15788]
16. Fix a bug where replication control message were not portable between
replication clients with different endian architectures. [#15793]
17. Add a configuration option to turn off Replication Manager's special
handling of elections in 2-site groups. [#15873]
18. Fix a bug making it impossible to call replicationManagerAddRemoteSite
in the Java API after having called replicationManagerStart. [#15875]
19. Fix a bug where the DB_EVENT_REP_STARTUPDONE event could be triggered
too early. [#15887]
20. Fix a bug where the rcvd_ts timestamp is reset when the user just
changes the threshold. [#15895]
21. Fix a bug where the master in a 2-site replication group might wait
for client acknowledgement, even when there was no client connected.
[#15927]
22. Fix a bug, clean up and restart internal init if master log is gone.
[#16006]
23. Fix a bug, ignore page messages that are from an old internal init.
[#16075] [#16059]
24. Fix a bug where checkpoint records do not indicate a database was a
named in-memory database. [#16076]
25. Fix a bug with in-memory replication, where we returned with the log
region mutex held in an error path, leading to self-deadlock. [#16088]
26. Fix a bug which causes the DB_REP_CHECKPOINT_DELAY setting in
rep_set_timeout() to be interpreted in seconds, rather than
microseconds. [#16153]
XA Resource Manager Changes:
1. Fix a bug where the DB_ENV->failchk method and replication in general
could fail in database environments configured for XA. [#15654]
Locking Subsystem Changes:
1. Fix a bug causing a lock or transaction timeout to not be set properly
after the first timeout triggers on a particular lock id. [#15847]
2. Fix a bug that would cause a trap if DB_ENV->lock_id_free was passed
an invalid locker id. [#16005]
3. Fix a bug when thread tracking is enabled where an attempt is made to
release a mutex that is not lock. [#16011]
Logging Subsystem Changes:
1. Fix a bug, handle zero-length log records doing HA sync with in-memory
logs. [#15838]
2. Fix a bug that could cause DB_ENV->failcheck to leak log region
memory. [#15925]
3. Fix a bug where the abort of a transaction that opened a database
could leak log region memory. [#15953]
4. Fix a bug that could leak memory in the DB_ENV->log_archive interface
if a log file was not found. [#16013]
Memory Pool Subsystem Changes:
1. Fix multiple MVCC bugs including a race, which could result in
incorrect data being returned to the application. [#15653]
2. Fixed a bug that left an active file in the buffer pool after a
database create was aborted. [#15918]
3. Fix a bug where there could be uneven distribution of pages if a
single database and multiple cache regions are configured. [#16015]
4. Fix a bug where DB_MPOOLFILE->set_maxsize was dropping the wrong mutex
after open. [#16050]
Mutex Subsystem Changes:
1. Fix a bug where mutex contention in database environments configured
for hybrid mutex support could result in performance degradation.
[#15646]
2. Set the DB_MUTEX_PROCESS_ONLY flag on all mutexes in private
environments, they can't be shared and so we can use the faster,
intra-process only mutex implementations [#16025]
3. Fix a bug so that mutexes are now removed from the environment
signature if mutexes are disabled. [#16042]
Transaction Subsystem Changes:
1. Fix a bug that could cause a checkpoint to selfblock attempting to
flush a file, when the file handle was closed by another thread during
the flush. [#15692]
2. Fix a bug that could cause DB_ENV->failcheck to hang if there were
pending prepared transactions in the environment. [#15925]
3. Prepared transactions will now use the sync setting from the
environment. Default to flushing the log on commit (was nosync).
[#15995]
4. If __txn_getactive fails, we now return with the log region mutex
held. This is not a bus since __txn_getactive cannot really fail.
[#16088]
Utility Changes:
1. Update db_stat with -x option for mutex stats
2. Fix an incorrect assumption about buffer size when getting an overflow
page in db_verify. [#16064]
Configuration, Documentation, Sample Application, Portability and Build
Changes:
1. Fix an installation bug where the Berkeley DB PHP header file was not
installed in the correct place.
2. Merge the run-time configuration sleep and yield functions. [#15037]
3. Fix Handle_DEAD and other expected replication errors in the C++
sample application ReqQuoteExample.cpp. [15568]
4. Add support for monotonic timers. [#15670]
5. Fix bugs where applications using the db_env_func_map and
db_env_func_unmap run-time configuration functions could not join
existing database environments, or open multiple DB_ENV handles for a
single environment. [#15930]
6. Add documentation about building Berkeley DB for VxWorks 6.x.
7. Remove the HAVE_FINE_GRAINED_LOCK_MANAGER flag, it is obsolete in 4.7.
8. Fix a bug in ex_rep, add a missing break which could cause a segment
fault.
9. Fix build warnings from 64 bit Windows build. [#16029]
10. Fix an alignment bug on ARM Linux. Force the assignment to use
memcpy. [#16125]
11. Fix a bug in the Windows specific code of ex_sequence.c, where there
was an invalide printf specifier. [#16131]
12. Improve the timer in ex_tpcb to use high resolution timers. [#16154]
13. Mention in the documentation that env->open() requires DB_THREAD to be
specified when using repmgr. [#16163]
14. Disable support for mmap on Windows CE. The only affect is that we do
not attempt to mmap small read only databases into the mpool. [#16169]

cp -pr on Solaris mysteriously and silently fails to copy the entire
directory structure. Spotted in bulk build.
|
|
The configure script checks for sizeof(FILE), which is an opaque type.
It can be argued that it should check for FILE* instead because that's
what it uses, but take the shortest path of resistance and disable
the check on DragonFly. Upstream is aware of the issue.
|

At least, all db4>=4.6.21 have it.
Add same trick as db2/db3.
Fixed link problem that expect db-1.85 compat library is -ldb, like a PR 37647.

* Fix a bug where mutex contention in database environments configured for
hybrid mutex support could result in performance degradation.
* Fix a bug where closing a database handle after aborting a transaction
which included a failed open of that database handle could result in
application failure.
* Fix multiple MVCC bugs including a race which could result in incorrect
data being returned to the application.
* Fix a bug where a database store into a Hash database could self-deadlock
in a database environment configured for the Berkeley DB Concurrent Data
Store product and with a free-threaded DB_ENV or DB handle.
* Fix an installation bug where Berkeley DB's PHP header file was not installed
in the correct place.

Multi-Version Concurrency Control (MVCC)
improves performance of highly concurrent, mixed read/write systems
by giving each user their own snapshot of the database and managing
concurrent changes by many users
Non-stop Upgrades
enables a replicated Oracle Berkeley DB system to be upgraded
without downtime. For customers that must maintain 99.999 percent

RECOMMENDED is removed. It becomes ABI_DEPENDS.
BUILDLINK_RECOMMENDED.foo becomes BUILDLINK_ABI_DEPENDS.foo.
BUILDLINK_DEPENDS.foo becomes BUILDLINK_API_DEPENDS.foo.
BUILDLINK_DEPENDS does not change.
IGNORE_RECOMMENDED (which defaulted to "no") becomes USE_ABI_DEPENDS
which defaults to "yes".
Added to obsolete.mk checking for IGNORE_RECOMMENDED.
I did not manually go through and fix any aesthetic tab/spacing issues.
I have tested the above patch on DragonFly building and packaging
subversion and pkglint and their many dependencies.
I have also tested USE_ABI_DEPENDS=no on my NetBSD workstation (where I
have used IGNORE_RECOMMENDED for a long time). I have been an active user
of IGNORE_RECOMMENDED since it was available.
As suggested, I removed the documentation sentences suggesting bumping for
"security" issues.
As discussed on tech-pkg.
I will commit to revbump, pkglint, pkg_install, createbuildlink separately.
Note that if you use wip, it will fail! I will commit to pkgsrc-wip
later (within day).

developer is officially maintaining the package.
The rationale for changing this from "tech-pkg" to "pkgsrc-users" is
that it implies that any user can try to maintain the package (by
submitting patches to the mailing list). Since the folks most likely
to care about the package are the folks that want to use it or are
already using it, this would leverage the energy of users who aren't
developers.

Changes since Berkeley DB 4.4.16:
1. Add support for Visual Studio 2005. [#13521]
2. Fix a bug with in-memory transaction logs when files wrapped
around the buffer. [#13589]
3. Fix a bug where we needed to close replication's open files during
replication initialization. [#13623]
4. Fix a bug which could leave locks in the environment if database
compaction was run in a transactional environment on a non-transactional
database. This might have also have triggered deadlocks if the database
was opened transactionally. [#13680]
5. Fix a bug where setting the DB_REGISTER flag could result in
unnecessarily running recovery, or corruption of the registry file on
Windows systems. [#13789]
6. Fix a bug in Database.compact that could cause JVM crashes or
NullPointerException. [#13791]
7. Fix a bug that would cause a trap if an environment was opened
specifying DB_REGISTER and the environment directory could not be found.
[#13793]
8. Fix a buffer overflow bug when displaying process and thread IDs
in the Berkeley DB statistics output. [#13796]
9. Fix a bug where if there is insufficient memory for a database key
in a DBT configured to return a key value into user-specified memory, the
cursor is moved forward to the next entry in the database, which can cause
applications to skip key/data pairs. [#13815]
10. Fix a bug that could cause the loss of an update to a QUEUE database
in a hot backup. [#13823]
11. Fix a bug where retrieval from a secondary index could result in a
core dump. [#13843]
12. Fix a bug that could cause part of the free list to become unlinked
if a btree compaction was rolled back due to a transaction abort. [#13891]
13. Fix a bug with in-memory logging that could cause a race condition to
corrupt the logs. [#13919]
[no shlib major bump this time, yay]

4.3.28, so there are no API changes, and applications may be upgraded
by relinking against db4-4.3.29. We stop pretending to support a
"java" package option since we never even bothered with handling the
PLIST differences. Changes from version 4.3.28 include:
* The on-disk log format has changed.
* Add support for lightweight, transactionally protected Sequence
Number generation.
* Add support for Degree 2 isolation.
* Add election generation information to replication to support Paxos
compliance.
* A huge number of bug fixes, including eliminating some instances of
application deadlock and memory leak fixes.
* Some minor performance enhancements.
