Revision history for DBM::Deep. 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 0.98 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 - Added Devel::Cover report to DBM::Deep POD - Test coverage improved to 89.6% (and climbing) - The following methods have been renamed to reflect their private nature: - init() is now _init() - open() is now _open() - close() is now _close() - load_tag() is now _load_tag() - index_lookup() is now _index_lookup() - add_bucket() is now _add_bucket() - get_bucket_value() is now _get_bucket_value() - delete_bucket() is now _delete_bucket() - bucket_exists() is now _bucket_exists() - find_bucket_list() is now _find_bucket_list() - traverse_index() is now _traverse_index() - get_next_key() is now _get_next_key() - copy_node() is now _copy_node() - throw_error() is now _throw_error() - The various tied classes have been broken out. This means that testing "ref( $obj ) eq 'DBM::Deep'" will now fail. The correct test is "eval { $obj->isa( 'DBM::Deep' ) }". - The various methods like push and delete now have the same return values as the standard builtins. - 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+). - 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) - You can now pass in an optional filehandle to the constructor 0.95 Oct 12 13:58:00 2005 Pacific - Added optional autobless flag to preserve and restore blessed hashes - Fixed bug where 0 could not be fetched using get_next_key - Fixed bug where tie() constructor didn't accept a hash ref for args - optimize() now preserves user/group/permissions - Errors are now FATAL (meaning it calls die()), unless you set debug flag 0.94 Apr 13 19:00:26 2004 Pacific - Fixed bug reported by John Cardenas (corruption at key level when replace of less data was done on bucket) 0.93 Feb 15 19:53:17 2004 Pacific - Fixed optmize() on Win32 where orig file couldn't be overwritten unless filehandle was closed first. This change introduces a potential race condition when using locking and optmize() on Win32, but it can be fixed in the future using a soft copy instead of Perl's rename(). 0.92 Feb 12 19:10:22 2004 Pacific - Fixed bug where passing a reference to a different DBM::Deep object would still result in an internal reference. - Added export() method for recursively extracting hashes/arrays into standard in-memory Perl structures. - Added import() method for recursively importing existing Perl hash/ array structures - Fixed bug where optimize() wouldn't work if base level of DB was an array instead of a hash. 0.91 Feb 12 02:30:22 2004 Pacific - Fixed bug with splice() when length of removed section was 0 - Updated POD re: circular refs and optimize() - Had to jump version numbers to 0.91 because in previous releases I used only a single digit after the decimal which was confusing the CPAN indexer. 0.10 Feb 11 08:58:35 2004 Pacific - Fixed bug where default file mode was CLEARING files (Thanks Rich!) - Added experimental support for circular references - Fixed bugs in shift(), unshift() and splice() where nested objects in array would be recursively re-stored as basic hashes/arrays - Fixed typos in POD docs 0.9 Feb 10 03:25:48 2004 Pacific - Added Filters for storing/fetching keys/values - Added hook for supplying own hashing algorithm - FIxed some typos in POD docs, added new sections 0.8 Feb 8 02:38:22 2004 Pacific - Renamed to DBM::Deep for CPAN - Added optimize() method for rekindling unused space - Now returning hybrid tie()/OO object from new() - Basic error handling introduced - Added debug mode for printing errors to STDERR - Added TYPE_HASH and TYPE_ARRAY constants for "type" param - Added clone() method for safe copying of objects - Wrote POD documentation - Added set_pack() function for manipulating LONG_SIZE / LONG_PACK - Added aliases for most tied functions for public use - Now setting binmode() on FileHandle for Win32 - Added 45 unit tests 0.7 Jan 4 11:31:50 2003 UTC - Renamed to DeepDB - Changed file signature to DPDB (not compatible with older versions) - Converted array length to packed long instead of sprintf()ed string 0.6 Dec 31 15:12:03 2002 UTC - Some misc optimizations for speed 0.5 Oct 18 08:55:29 2002 UTC - support for force_return_next parameter in traverse_index() method for ultra-fast combined key search/removal 0.4 Oct 15 20:07:47 2002 UTC - now making sure filehandle is open for all DB calls 0.3 Oct 3 19:04:13 2002 UTC - fixed bug that could cause corrupted data when using locking 0.2 Aug 6 16:37:32 2002 UTC - Removed base index caching, as it can cause problems when two processes are populating the db at the same time (even with locking) 0.1 Jun 3 08:06:26 2002 UTC - initial release
