Revision history for DBM::Deep.
-0.97 ??? ?? ??:??:?? 2006 Pacific
+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 ****
+ - Start the process of optimization.
+
+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.
+ - the 16 and 22 tests are now re-enabled.
+ - Yes, this means that real references work. See t/45_references.t
+
+1.0002 Sep 20 22:00:00 2007 EDT
+ - (This version is compatible with 1.0001)
+ - Expanded _throw_error() so that it provides better information.
+ (Thanks brian d foy!)
+ - Fixed how shift, unshift, and splice work when there are references
+ being moved. It now no longer dies.
+ - Added diag in t/17_import.t to note that the failing tests on blead
+ are due to Clone being broken, not DBM::Deep. The tests will still
+ fail because I don't want users to install something that's broken
+ and deal with those bug reports.
+
+1.0001 Mar 12 16:15:00 2007 EDT
+ - (This version is compatible with 1.0000)
+ - Added a missing dependency on IO::Scalar (RT #25387)
+ - Fixed how t/44_upgrade_db.t and utils/upgrade_db.pl worked
+ - utils/upgrade_db.pl now uses #!perl, not #!/usr/bin/perl
+ - t/44_upgrade_db.t now explicitly calls $^X
+ (Thanks merlyn!)
+
+1.0000 Feb 26 22:30:00 2007 EST
+ - THIS VERSION IS INCOMPATIBLE WITH FILES FROM ALL OTHER PRIOR VERSIONS.
+ - To aid in this form of upgrades, DBM::Deep now checks the file format
+ version to make sure that it knows how to read it.
+ - db_upgrade.pl was added to utils/. This will -NOT- install onto
+ your system. This is deliberate.
+ - db_upgrade.pl will not handle developer release file formats. This
+ is due to the fact that all developer releases in preparation for a
+ given release share the same file version, even though the file
+ format may change. This is deliberate.
+ - Importing no longer takes place within a transaction
+ - The following parameters were added:
+ - data_sector_size - this determines the default size of a data sector.
+ - Correctly handle opening readonly files
+
+0.99_04 Jan 24 22:30:00 2007 EST
+ - Added the missing lib/DBM/Deep.pod file to the MANIFEST
+ - Fixed a poorly-designed test that was failing depending on what Clone::Any
+ was using.
+ - All "use 5.6.0;" lines are now "use 5.006_000;" to avoid warnings about
+ unsupported vstrings in 5.9.x
+
+0.99_03 Jan 23 22:30:00 2007 EST
+ - THIS VERSION IS INCOMPATIBLE WITH FILES FROM ALL OTHER PRIOR VERSIONS.
+ - The fileformat changed completely. I will be writing a converter, but
+ it's not there right now. Do NOT expect that this module will
+ correctly detect older versions and handle them sanely. Sanity will be
+ there for 1.00, but we're not there yet, are we?
+ - Converted to use FileHandle::Fmode to handle filehandle status checks
+ - Fixed bug with deleting already-deleted items on Win32 (reported by Nigel Sandever)
+ - The guts of how transactions work has been rewritten to better handle
+ some edgecases. This required a complete rewrite of the engine.
+ - Freespace management is now in place. It's not perfect, but it's there.
+ - The rewrite of the engine required a rewrite of how first_key/next_key
+ was implemented. This should result in significant speed improvements.
+ - Self-reference has been removed. This means you cannot do:
+ $db->{foo} = { x => 'y' };
+ $db->{bar} = $db->{foo};
+ I hope to be able to return this functionality by 1.00, but I cannot
+ promise anything. To do this properly, it requires refcounting in order
+ to correctly handle deletions and transactions. Once you move away from
+ a simple tree, everything becomes really hard.
+
+0.99_02 Apr 28 05:00:00 2006 Pacific
+ - Added missing file to the MANIFEST
+
+0.99_01 Apr 27 18:00:00 2006 Pacific
+ - Added explicit dependency on Perl 5.6.0
+ - Digest::MD5 requires 5.6.0
+ - Sub::Uplevel (dep of Test::Exception) requires 5.6.0
+ - Removed error()/clear_error()
+ - All error-handling is done with die()
+ - Broke out DBM::Deep's code into DBM::Deep::Engine
+ - Tied variables can no longer be assigned to a DBM::Deep object.
+ - This includes cross-file assignments.
+ - Autovivification now works
+ - This is a consequence of the fact that all assignments are tied.
+ - set_pack() and set_digest() have been removed.
+ - Instead, you will now pass the appropriate values into new()
+ - A pack_size parameter has been added to make 64-bit files easier
+ - Transactions now work
+
+0.983 Apr 10 20:00:00 2006 Pacific
+ - Added patch inspired by Jeff Janes (Thanks!)
+ - Autovivification now works correctly
+ - The following now works correctly
+ my %hash = ( a => 1 );
+ $db->{hash} = \%hash;
+ $hash{b} = 2;
+ cmp_ok( $db->{hash}{b}, '==', 2 );
+ - (RT#18530) - DBM::Deep now plays nicely with -l
+
+0.982 Mar 08 11:00:00 2006 Pacific
+ - Fixed smoketests that were failing on Win32
+ - Added restriction for Perl 5.6.0 or higher.
+ - Digest::MD5 and Sub::Uplevel (dep of Test::Exception) require 5.6+
+
+0.981 Mar 06 11:00:00 2006 Pacific
+ - (RT#17947) - Fixed test that was failing on older Perls
+
+0.98 Feb 28 11:00:00 2006 Pacific
+ - Added in patch by David Cantrell to allow use of DATA filehandle
+ - Fixed bug where attempting to export() a structure that used autobless would die
+ - Fixed arraytest slowness by localizing $SIG{__DIE__} to prevent Test::Builder's
+ $SIG{__DIE__} from being called. (q.v. http://perldoc.perl.org/functions/eval.html)
+ - More methods have been made private:
+ - root() is now _root()
+ - base_offset() is now _base_offset()
+ - fh() is now _fh()
+ - type() is now _type()
+ - precalc_sizes() is now _precalc_sizes()
+
+0.97 Feb 24 10:00:00 2006 Pacific
- Reorganization of distribution to a more standard layout
- Migration to Module::Build with EU::MM backwards compatibility
- Migration of all tests to use Test::More and Test::Exception
- TIEARRAY and TIEHASH now check their parameters more thoroughly
- Negative indices for arrays works as expected, including throwing the appropriate
errors.
- - RT #16877 is fixed (DBM::Deep broken with Perl 5.9.3+)
- - TODO: RT #14893 is fixed (tie() and new() use different parameter lists)
+ - RT #16877 is fixed (DBM::Deep broken with Perl 5.9.3+).
+ - RT #14893 is fixed (tie() and new() use different parameter lists).
+ - A bug with optimize and threading is fixed.
+ - autobless has received some attention, resulting in a number of bugs fixed.
+ - Removed mode option as it just caused confusion.
+ - Removed volatile option as it is pretty useless (use locking instead)
+ - Locking now implicitly enables autoflush
0.96 Oct 14 09:55:00 2005 Pacific
- Fixed build (OS X hidden files killed it)
