Revision history for DBM::Deep.
-1.0009_01 Sep 24 14:00:00 2007 EDT
+1.0019_003 Jan XX XX:XX:00 2010 EST
+ (This is the third developer release for 1.0020.)
+ (This version is compatible with 1.0014)
+ - Fixed problem where "./Build test" wouldn't actually -do- anything.
+ - (No-one apparently tried to install this till Steven Lembark. Thanks!)
+ - Fixed speed regression with keys in the File backend.
+ - Introduced in 1.0019_002 to fix #50541
+ - (RT #53575) Recursion failure in STORE (Thanks, SPROUT)
+
+1.0019_002 Jan 05 22:30:00 2010 EST
+ (This is the second developer release for 1.0020.)
+ (This version is compatible with 1.0014)
+ - Fixed bug where attempting to store a value tied to something other than
+ DBM::Deep would leave the file flocked.
+ - Added support for DBD::SQLite
+ - Build.PL has been extended to support sqlite vs. mysql
+ - Storage::DBI now detects between the two DBDs
+ - (RT #51888) Applied POD patch (Thanks, FWIE!)
+ - (RT #44981) Added VERSION to ::Array, ::Engine, and ::Hash
+ - Removed extraneous slashes from POD links (Thanks ilmari!)
+ - (RT #50541) Fixed bug in clear() for hashes in the File backend.
+ - This has caused a regression in speed for clear() when clearing
+ large hashes using running with the File backend. ->clear() (on my
+ machine) now takes ( N / 40 ) ** (1.66) seconds. So, clearing 4000
+ keys (as is the test in t/03_bighash.t) would take ~2070 seconds.
+ - (RT #40782) Fixed bug when handling a key of '0' (Thanks Sterling!)
+ - (RT #48031) Fixed bug with localized $, (Thanks, SPROUT!)
+
+1.0019_001 Dec 31 22:00:00 2009 EST
+ (This is the first developer release for 1.0020.)
+ (This version is compatible with 1.0014)
+ - DBM::Deep has been refactored to allow for multiple engines. There are two
+ engines built so far:
+ - File (the original engine)
+ - DBI (an engine based on DBI)
+ - The DBI engine has only been tested on MySQL and isn't transactional.
+ - InnoDB sucks horribly. When run in a sufficient isolation mode, it
+ creates deadlocks.
+ - A custom Build.PL has been written to allow for running tests under
+ CPAN.pm against the various engines.
+ - This also allows running the long tests under CPAN.pm
+ - This has meant a ton of refactoring. Hopefullly, this refactoring will
+ allow finding some of the niggly bugs more easily. Those tests have not
+ been enabled yet. That's the next developer release.
+ - Hopefully, this multi-engine support will allow deprecation of the file
+ format in the future.
+
+1.0014 Jun 13 23:15:00 2008 EST
+ - (This version is compatible with 1.0013)
+ - Fix for RT#36781 (t/44 has an unrequired dependency)
+ - lock() has been aliased to lock_exclusive(). There is now
+ a lock_shared() method. The :flock constants are no longer
+ imported into the DBM::Deep namespace.
+ **** THIS IS AN API CHANGE ****
+
+1.0013 Jun 13 23:15:00 2008 EST
+ - (This version is compatible with 1.0012)
+ - Fix for RT#30144 (Optimization failure on Win32)
+ - Fixed a bug in reindex_entry (Thanks, Wulfram Humann!)
+
+1.0012 Jun 09 15:00:00 2008 EST
+ - (This version is compatible with 1.0011)
+ - Fix for RT#30085 (Remove dependency on XS module)
+ - Thank you very much tachyon-II@Perlmonks!!
+ - This also resolves RT#35424 (DBM::Deep breaks XML::Twig).
+ - Updated the POD with fixes that were made, but still on the TODO list.
+ - Bypass for RT#36419 (t/44_upgrade_db.t fails on *BSD)
+ - We're just going to skip that for now. It's a number-of-processes-open
+ issue. Best is to do a port to another module to do the heavy lifting.
+
+1.0011 May 27 15:00:00 2008 EST
+ - (This version is compatible with 1.0010)
+ - A test has the wrong plan.
+
+1.0010 May 27 12:00:00 2008 EST
+ - (This version is compatible with 1.0009)
+ - Fix for RT#35140 (invalid POD links)
+ - Fix for RT#34819 (Cannot assign the same value back to the same location)
+ - Fix for RT#29957 (Cannot assign the same value back to the same location)
+ - Fix for RT#33863 (Cannot shift an arrayref from an array)
+ - When something is deleted from a DB, the value is export()ed, allowing it
+ to be saved.
+ - This exporting is only done if the refcount == 0 after the deletion.
+
+1.0009 Mar 19 12:00:00 2008 EDT
+ - (This version is compatible with 1.0008)
+ - Internal refactorings to prepare for some optimizations.
+ - _fh() has been removed. It was marked as private, so don't complain.
+ - Skip a test that was spuriously failing on Win32 (Thanks, Alias!)
+
+1.0008 Mar 09 20:00:00 2008 EDT
+ - (This version is compatible with 1.0007)
+ - Fixed a number of Win32 issues (Reported by Steven Samelson - thank you!)
+ - Much thanks to Nigel Sandever and David Golden for their help
+ debugging the issues, particularly with DBM::Deep's usage of
+ File::Temp (which removes a number of warnings).
+ - Autovivification now works on Win32. It turns out that when a
+ process takes a shared flock on a file, it's not allowed to write to
+ it under Win32, unlike *nix. This is probably a good catch.
+ - Note: The fix is a hack. All locks are now exclusive until a
+ better fix is found.
+
+1.0007 Jan 10 00:00:00 2008 EDT
+ - (This version is compatible with 1.0006)
+ - Applied a patch+failing test submitted by sprout@cpan.org. Thanks!
+ - Turns out that the case of 17 keys with the same first character in the
+ MD5 hash wasn't being tested for. This was a crashbug.
+ - A fix has been made to upgrade_db.pl (RT# 30067)
+ - The version determinations were in the wrong order or evaluation. This
+ meant that upgrade_db.pl wouldn't work as expected (or at all).
+ - Added a minimum Pod::Usage requirement (RT# 29976)
+ - It's an optional item in Build.PL
+ - utils/upgrade_db.pl now checks for that version, as does the test.
+
+1.0006 Oct 01 23:15:00 2007 EDT
+ - (This version is compatible with 1.0005)
+ - Removed Clone and replaced it with a hand-written datastructure walker.
+ - This greatly reduces the footprint of a large import
+ - This bypasses a failure of Clone under Perl 5.9.5
+ - Moved t/37_delete_edge_cases.t to t_attic because it wasn't really used
+ - import() has a stricter API now. This is a potentially incompatible API
+ change. Only HASH and ARRAY refs are now allowed and they must match the type
+ of the object being imported into.
+
+1.0005 Oct 01 11:15:00 2007 EDT
+ - (This version is compatible with 1.0004)
+ - Added proper singleton support. This means that the following now works:
+ $db->{foo} = [ 1 .. 3];
+ my $x = $db->{foo};
+ my $y = $db->{foo};
+ is( $x, $y ); # Now passes
+ - This means that Data::Dumper now properly reports when $db->{foo} = $db->{bar}
+
+1.0004 Sep 28 12:15:00 2007 EDT
+ - (This version is compatible with 1.0003)
+ - Fixed the Changes file (wrong version was displayed for 1.0003)
+ - Added filter sugar methods to be more API-compatible with other DBMs
+ - This was added to support a patch provided to IO::All so it can
+ use DBM::Deep as a DBM provider.
+ - Implemented _dump_file in order to display the file structure. As a
+ result, the following bugs were fixed:
+ - Arrays and hashes now clean up after themselves better.
+ - Bucketlists now clean up after themselves better.
+ - Reindexing properly clears the old bucketlist before freeing it.
+
+1.0003 Sep 24 14:00:00 2007 EDT
- THIS VERSION IS INCOMPATIBLE WITH FILES FROM ALL OTHER PRIOR VERSIONS.
- Further fixes for unshift/shift/splice and references (RT# 29583)
- To fix that, I had to put support for real references in.
