Revision history for perl module BDB.

TODO: DB_RECNUM/DB_SET_RECNO?

1.88 Wed Mar 31 02:43:42 CEST 2010

• a double fork partially killed the event pipe (great testcase by dormando). affects IO::AIO, BDB and Async::Interrupt.
• suck steve's dick and rename our symbols to avoid colliding with nonstandard identifier spam on the broken os x pseudo-os. affects IO::AIO and BDB.

1.87 Tue Dec 22 03:06:09 CET 2009

• db 4.8 has removed XA resource manager functionality, cope with it.
• add LOGVERSION, LOGVERSION_LATCHING, LOGOLDVER symbols.

1.86 Fri Dec 4 16:03:21 CET 2009

• port to broken loser platform.

1.85 Thu Nov 12 03:22:21 CET 2009

• speed up object creation/type checking considerably by caching the stashes.

1.84 Wed Aug 5 13:52:21 CEST 2009

• require common sense.
• use schmorp.h for pipe, taking advantage of eventfd.
• fix a bug in event pipe creation code on win32.

1.83 Sun Jan 11 01:52:56 CET 2009

• fix db_upgrade, add db_verify.

1.82 Sun Jan 4 11:22:44 CET 2009

• use our own socketpair emulation (stolen from libev), as perl's doesn't work on vista, which returns fantasy port numbers in getpeer/sockname.

1.81 Tue Oct 21 04:20:25 CEST 2008

• check that mutable arguments can be downgraded - this /very indirectly) ensures that output variables won't have spurious utf-8 flags.
• fix opmode checdk in dbcget, dbcpget again.
• allow undef/default arguments for db_compact, for a crash-free tomorrow!
• fix a memleak in db_key_range.
• started a common pitfdalls section.
• added db_env_log_archive.
• added db->set_pagesize.
• added BDB::IGNORE_LEASE.
• reworked documentation structure.

1.801 Mon Sep 29 04:58:03 CEST 2008

• removed ptrace.h and user.h includes thta have been left in erronously.
• "port" to buggy windows compilers. again.

1.8 Sat Sep 27 14:01:37 CEST 2008

• non-callback requests will now - by default - be executed in the foreground, which is much faster, but doesn't allow parallel processing of other, event-based, requests.
• functions that modify their arguments now croak when a constant is passed to them.
• dbcget/dbcpget requests did not correctly test the operation flags.
• db_pget now correctly updates the pkey argument.
• keep references to the passed env/db/etc. objects so they can't get destroyed while requests are still outstanding.
• fixed a few minor stack issues.

1.71 Tue Jul 29 05:30:24 CEST 2008

• add const char * to typemap for possible 5.6 support.
• untested support for db4.3.
• berkelydb needs seriously larger stacksizes (on x86 at least) then what the default xthread.h provides.

1.7 Thu Jul 17 14:09:25 CEST 2008

• use a totally different mechanism to pass callbacks to requests (see manpage).
• optional arguments before the callback can now be left out.
• use less memory per request, probably be a bit faster, too.
• fix a memory leak (callbacks were never freed).
• add a basic testsuite.
• add (untested) support for cdsgroup_begin and db_exists.
• make BDB::VERSION compatible to UNIVERSAL::VERSION.

1.6 Tue Jul 8 10:34:58 CEST 2008

• add new BDB::VERSION function for easy version checks.
• work around broken bsd headers once more.
• support for berkeley db 4.7 added.
• add support for log_set_config and it's constants, and set_intermediate_dir_mode.
• add db_env_dbrename and db_env_dbremove.

1.5 Sat May 10 22:22:42 CEST 2008

• port to solaris perls configured for old posix (analysed by Jost Krieger).
• do our own stack memory management for threads - linux allocates outrageous amounts of VM (not so bad unless you use mlockall...), which severely limits the number of threads on 32-bit arches: stack size is the larger of PTHREAD_STACK_MIN and 4096 * sizeof (long) (usually this is 16..64k).
• support AnyEvent::BDB.

1.45 Sun Mar 30 10:01:00 CEST 2008

• work around win32 perl's broken filehandles (this cannot work in all cases, so watch out).

1.44 Sun Mar 30 08:28:11 CEST 2008

• encode filenames as utf-8 (for bdb/win32) or binary (everywhere else).
• patch $! to support stringification of BDB errno values (utter hack, this should be pluggable :).
• fix prototypes of (void) functions.

1.43 Sun Jan 13 11:52:49 CET 2008

• differentiate between nuked and undef objects, so as to not throw an exception when destroying closed handles.

1.42 Tue Dec 25 15:22:50 CET 2007

• do not automatically call set_thread_count.

1.41 Sat Dec 22 08:32:41 CET 2007

• add cursor->set_priority.
• minor optimisations and checks.
• port to microsoft pseudo-C again.

1.4 Wed Dec 12 02:20:39 CET 2007

• new globals BDB::VERSION and ..VERSION_STRING.
• add db_upgrade.
• do not die in DESTROY after explicit db_close and similar operations.

1.3 Fri Dec 7 14:36:25 CET 2007

• db_put and c_put leaked memory like hell (reported by Danny).
• de-IO::AIO-ify the documentation.
• port to microsofts pseudo-C from hell.
• added mutex_set_increment, mutex_set_tas_spins and mutex_set_max, mutex_set_align.

1.2 Tue Dec 4 11:12:47 CET 2007

• after fork, invest some work to make sure that the poll_fileno stays stable (by dup2'ing the new fd over the old one), to make it easier for programs/libs that don't control their forking behaviour and cannot recreate their watchers.
• added missing DB::RDONLY (reported by Danny).

1.1 Sun Sep 16 20:15:55 CEST 2007

• flag and check TXN_DEADLOCK flag for easier transaction programming (see db_txn_finish).
• new custom db_txn_finish request.
• improved docs.

1.0 Mon Aug 13 14:02:42 CEST 2007

• some updates for db 4.6.
• vastly improved documentation, i.e. there is some now.
• this module has been tested a lot in the Crossfire TRT server.

0.5 Sun Jul 8 16:57:03 CEST 2007

• port to db 4.4.20 (probably any 4.4 version).
• added bdb error constants.
• add set_errfile/set_msgfile/set_verbose.
• shared code between IO::AIO and BDB.
• upgrade to xthread.h from IO::AIO for win32 compatibility.
• port to win32 (there is an unexplainable hang in db_sequence_get...).

0.1 Mon Mar 5 20:44:18 CET 2007

• cloned from IO::AIO.
