1 Revision history for DBM::Deep.
3 0.99_03 Jan ?? 00:00:00 2007 EDT
4 - THIS VERSION IS INCOMPATIBLE WITH FILES FROM ALL OTHER PRIOR VERSIONS.
5 - The fileformat changed completely. I will be writing a converter, but
6 it's not there right now. Do NOT expect that this module will
7 correctly detect older versions and handle them sanely. Sanity will be
8 there for 1.00, but we're not there yet, are we?
9 - Converted to use FileHandle::Fmode to handle filehandle status checks
10 - Fixed bug with deleting already-deleted items on Win32 (reported by Nigel Sandever)
11 - The guts of how transactions work has been rewritten to better handle
12 some edgecases. This required a complete rewrite of the engine.
13 - Freespace management is now in place. It's not perfect, but it's there.
14 - The rewrite of the engine required a rewrite of how first_key/next_key
15 was implemented. This should result in significant speed improvements.
16 - Self-reference has been removed. This means you cannot do:
17 $db->{foo} = { x => 'y' };
18 $db->{bar} = $db->{foo};
19 I hope to be able to return this functionality by 1.00, but I cannot
20 promise anything. To do this properly, it requires refcounting in order
21 to correctly handle deletions and transactions. Once you move away from
22 a simple tree, everything becomes really hard.
24 0.99_02 Apr 28 05:00:00 2006 Pacific
25 - Added missing file to the MANIFEST
27 0.99_01 Apr 27 18:00:00 2006 Pacific
28 - Added explicit dependency on Perl 5.6.0
29 - Digest::MD5 requires 5.6.0
30 - Sub::Uplevel (dep of Test::Exception) requires 5.6.0
31 - Removed error()/clear_error()
32 - All error-handling is done with die()
33 - Broke out DBM::Deep's code into DBM::Deep::Engine
34 - Tied variables can no longer be assigned to a DBM::Deep object.
35 - This includes cross-file assignments.
36 - Autovivification now works
37 - This is a consequence of the fact that all assignments are tied.
38 - set_pack() and set_digest() have been removed.
39 - Instead, you will now pass the appropriate values into new()
40 - A pack_size parameter has been added to make 64-bit files easier
41 - Transactions now work
43 0.983 Apr 10 20:00:00 2006 Pacific
44 - Added patch inspired by Jeff Janes (Thanks!)
45 - Autovivification now works correctly
46 - The following now works correctly
47 my %hash = ( a => 1 );
50 cmp_ok( $db->{hash}{b}, '==', 2 );
51 - (RT#18530) - DBM::Deep now plays nicely with -l
53 0.982 Mar 08 11:00:00 2006 Pacific
54 - Fixed smoketests that were failing on Win32
55 - Added restriction for Perl 5.6.0 or higher.

59 - (RT#17947) - Fixed test that was failing on older Perls
61 0.98 Feb 28 11:00:00 2006 Pacific
62 - Added in patch by David Cantrell to allow use of DATA filehandle
63 - Fixed bug where attempting to export() a structure that used autobless would die
64 - Fixed arraytest slowness by localizing $SIG{__DIE__} to prevent Test::Builder's
65 $SIG{__DIE__} from being called. (q.v. http://perldoc.perl.org/functions/eval.html)
66 - More methods have been made private:
67 - root() is now _root()
68 - base_offset() is now _base_offset()
70 - type() is now _type()
71 - precalc_sizes() is now _precalc_sizes()
73 0.97 Feb 24 10:00:00 2006 Pacific
74 - Reorganization of distribution to a more standard layout
75 - Migration to Module::Build with EU::MM backwards compatibility
76 - Migration of all tests to use Test::More and Test::Exception
77 - Added Devel::Cover report to DBM::Deep POD
78 - Test coverage improved to 89.6% (and climbing)
79 - The following methods have been renamed to reflect their private nature:
80 - init() is now _init()
81 - open() is now _open()
82 - close() is now _close()
83 - load_tag() is now _load_tag()
84 - index_lookup() is now _index_lookup()
85 - add_bucket() is now _add_bucket()
86 - get_bucket_value() is now _get_bucket_value()
87 - delete_bucket() is now _delete_bucket()
88 - bucket_exists() is now _bucket_exists()
89 - find_bucket_list() is now _find_bucket_list()
90 - traverse_index() is now _traverse_index()
91 - get_next_key() is now _get_next_key()
92 - copy_node() is now _copy_node()
93 - throw_error() is now _throw_error()
94 - The various tied classes have been broken out. This means that testing
95 "ref( $obj ) eq 'DBM::Deep'" will now fail. The correct test is
96 "eval { $obj->isa( 'DBM::Deep' ) }".
97 - The various methods like push and delete now have the same return values as
98 the standard builtins.
99 - TIEARRAY and TIEHASH now check their parameters more thoroughly
100 - Negative indices for arrays works as expected, including throwing the appropriate
102 - RT #16877 is fixed (DBM::Deep broken with Perl 5.9.3+).
103 - RT #14893 is fixed (tie() and new() use different parameter lists).
104 - A bug with optimize and threading is fixed.
105 - autobless has received some attention, resulting in a number of bugs fixed.
106 - Removed mode option as it just caused confusion.
107 - Removed volatile option as it is pretty useless (use locking instead)
108 - Locking now implicitly enables autoflush
110 0.96 Oct 14 09:55:00 2005 Pacific
111 - Fixed build (OS X hidden files killed it)
112 - You can now pass in an optional filehandle to the constructor
114 0.95 Oct 12 13:58:00 2005 Pacific
115 - Added optional autobless flag to preserve and restore blessed hashes
116 - Fixed bug where 0 could not be fetched using get_next_key
117 - Fixed bug where tie() constructor didn't accept a hash ref for args
118 - optimize() now preserves user/group/permissions
119 - Errors are now FATAL (meaning it calls die()), unless you set debug flag
121 0.94 Apr 13 19:00:26 2004 Pacific
122 - Fixed bug reported by John Cardenas (corruption at key level when
123 replace of less data was done on bucket)
125 0.93 Feb 15 19:53:17 2004 Pacific
126 - Fixed optmize() on Win32 where orig file couldn't be overwritten unless
127 filehandle was closed first. This change introduces a potential race
128 condition when using locking and optmize() on Win32, but it can be
129 fixed in the future using a soft copy instead of Perl's rename().
131 0.92 Feb 12 19:10:22 2004 Pacific
132 - Fixed bug where passing a reference to a different DBM::Deep object
133 would still result in an internal reference.
134 - Added export() method for recursively extracting hashes/arrays into
135 standard in-memory Perl structures.
136 - Added import() method for recursively importing existing Perl hash/
138 - Fixed bug where optimize() wouldn't work if base level of DB was
139 an array instead of a hash.
141 0.91 Feb 12 02:30:22 2004 Pacific
142 - Fixed bug with splice() when length of removed section was 0
143 - Updated POD re: circular refs and optimize()
144 - Had to jump version numbers to 0.91 because in previous releases
145 I used only a single digit after the decimal which was confusing
148 0.10 Feb 11 08:58:35 2004 Pacific
149 - Fixed bug where default file mode was CLEARING files (Thanks Rich!)
150 - Added experimental support for circular references
151 - Fixed bugs in shift(), unshift() and splice() where nested objects
152 in array would be recursively re-stored as basic hashes/arrays
153 - Fixed typos in POD docs
155 0.9 Feb 10 03:25:48 2004 Pacific
156 - Added Filters for storing/fetching keys/values
157 - Added hook for supplying own hashing algorithm
158 - FIxed some typos in POD docs, added new sections
160 0.8 Feb 8 02:38:22 2004 Pacific
161 - Renamed to DBM::Deep for CPAN
162 - Added optimize() method for rekindling unused space
163 - Now returning hybrid tie()/OO object from new()
164 - Basic error handling introduced
165 - Added debug mode for printing errors to STDERR
166 - Added TYPE_HASH and TYPE_ARRAY constants for "type" param
167 - Added clone() method for safe copying of objects
168 - Wrote POD documentation
169 - Added set_pack() function for manipulating LONG_SIZE / LONG_PACK
170 - Added aliases for most tied functions for public use
171 - Now setting binmode() on FileHandle for Win32

176 - Changed file signature to DPDB (not compatible with older versions)
177 - Converted array length to packed long instead of sprintf()ed string
179 0.6 Dec 31 15:12:03 2002 UTC
180 - Some misc optimizations for speed
182 0.5 Oct 18 08:55:29 2002 UTC
183 - support for force_return_next parameter in traverse_index() method for
184 ultra-fast combined key search/removal
186 0.4 Oct 15 20:07:47 2002 UTC
187 - now making sure filehandle is open for all DB calls
189 0.3 Oct 3 19:04:13 2002 UTC
190 - fixed bug that could cause corrupted data when using locking
192 0.2 Aug 6 16:37:32 2002 UTC
193 - Removed base index caching, as it can cause problems when two processes
194 are populating the db at the same time (even with locking)
196 0.1 Jun 3 08:06:26 2002 UTC
