Revision history for perl module BDB.

TODO: DB_RECNUM/DB_SET_RECNO?

- maybe add faq: why doe sit crash (parallelity)
- why does it freeze (locking cursor/nocursor, deadlock put).
- DB_IGNORE_LEASE MULTIPLE_KEY 4.7?
1.81
        - 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 db_c_get, db_c_pget again.
        - allow undef/default arguments for db_compact, for a
          crash-free tomorrow!
        - added db->set_pagesize.
        - added BDB::IGNORE_LEASE.

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.
        - db_c_get/db_c_pget 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.
