1 Revision history for DBM::Deep.
3 0.99_04 Jan 24 22:30:00 2007 EDT
4 - Added the missing lib/DBM/Deep.pod file to the MANIFEST
5 - Fixed a poorly-designed test that was failing depending on what Clone::Any
7 - All "use 5.6.0;" lines are now "use 5.006_000;" to avoid warnings about
8 unsupported vstrings in bleadperl.
10 0.99_03 Jan 23 22:30:00 2007 EDT
11 - THIS VERSION IS INCOMPATIBLE WITH FILES FROM ALL OTHER PRIOR VERSIONS.
12 - The fileformat changed completely. I will be writing a converter, but
13 it's not there right now. Do NOT expect that this module will
14 correctly detect older versions and handle them sanely. Sanity will be
15 there for 1.00, but we're not there yet, are we?
16 - Converted to use FileHandle::Fmode to handle filehandle status checks
17 - Fixed bug with deleting already-deleted items on Win32 (reported by Nigel Sandever)
18 - The guts of how transactions work has been rewritten to better handle
19 some edgecases. This required a complete rewrite of the engine.
20 - Freespace management is now in place. It's not perfect, but it's there.
21 - The rewrite of the engine required a rewrite of how first_key/next_key
22 was implemented. This should result in significant speed improvements.
23 - Self-reference has been removed. This means you cannot do:
24 $db->{foo} = { x => 'y' };
25 $db->{bar} = $db->{foo};
26 I hope to be able to return this functionality by 1.00, but I cannot
27 promise anything. To do this properly, it requires refcounting in order
28 to correctly handle deletions and transactions. Once you move away from
29 a simple tree, everything becomes really hard.
31 0.99_02 Apr 28 05:00:00 2006 Pacific
32 - Added missing file to the MANIFEST
34 0.99_01 Apr 27 18:00:00 2006 Pacific
35 - Added explicit dependency on Perl 5.6.0
36 - Digest::MD5 requires 5.6.0
37 - Sub::Uplevel (dep of Test::Exception) requires 5.6.0
38 - Removed error()/clear_error()
39 - All error-handling is done with die()
40 - Broke out DBM::Deep's code into DBM::Deep::Engine
41 - Tied variables can no longer be assigned to a DBM::Deep object.
42 - This includes cross-file assignments.
43 - Autovivification now works
44 - This is a consequence of the fact that all assignments are tied.
45 - set_pack() and set_digest() have been removed.
46 - Instead, you will now pass the appropriate values into new()
47 - A pack_size parameter has been added to make 64-bit files easier
48 - Transactions now work
50 0.983 Apr 10 20:00:00 2006 Pacific
51 - Added patch inspired by Jeff Janes (Thanks!)
52 - Autovivification now works correctly
53 - The following now works correctly
54 my %hash = ( a => 1 );
57 cmp_ok( $db->{hash}{b}, '==', 2 );
58 - (RT#18530) - DBM::Deep now plays nicely with -l
60 0.982 Mar 08 11:00:00 2006 Pacific
61 - Fixed smoketests that were failing on Win32
62 - Added restriction for Perl 5.6.0 or higher.

66 - (RT#17947) - Fixed test that was failing on older Perls
68 0.98 Feb 28 11:00:00 2006 Pacific
69 - Added in patch by David Cantrell to allow use of DATA filehandle
70 - Fixed bug where attempting to export() a structure that used autobless would die
71 - Fixed arraytest slowness by localizing $SIG{__DIE__} to prevent Test::Builder's
72 $SIG{__DIE__} from being called. (q.v. http://perldoc.perl.org/functions/eval.html)
73 - More methods have been made private:
74 - root() is now _root()
75 - base_offset() is now _base_offset()
77 - type() is now _type()
78 - precalc_sizes() is now _precalc_sizes()
80 0.97 Feb 24 10:00:00 2006 Pacific
81 - Reorganization of distribution to a more standard layout
82 - Migration to Module::Build with EU::MM backwards compatibility
83 - Migration of all tests to use Test::More and Test::Exception
84 - Added Devel::Cover report to DBM::Deep POD
85 - Test coverage improved to 89.6% (and climbing)
86 - The following methods have been renamed to reflect their private nature:
87 - init() is now _init()
88 - open() is now _open()
89 - close() is now _close()
90 - load_tag() is now _load_tag()
91 - index_lookup() is now _index_lookup()
92 - add_bucket() is now _add_bucket()
93 - get_bucket_value() is now _get_bucket_value()
94 - delete_bucket() is now _delete_bucket()

96 - find_bucket_list() is now _find_bucket_list()
97 - traverse_index() is now _traverse_index()
98 - get_next_key() is now _get_next_key()
99 - copy_node() is now _copy_node()
100 - throw_error() is now _throw_error()
101 - The various tied classes have been broken out. This means that testing
102 "ref( $obj ) eq 'DBM::Deep'" will now fail. The correct test is
103 "eval { $obj->isa( 'DBM::Deep' ) }".
104 - The various methods like push and delete now have the same return values as
105 the standard builtins.
106 - TIEARRAY and TIEHASH now check their parameters more thoroughly
107 - Negative indices for arrays works as expected, including throwing the appropriate
109 - RT #16877 is fixed (DBM::Deep broken with Perl 5.9.3+).
110 - RT #14893 is fixed (tie() and new() use different parameter lists).
111 - A bug with optimize and threading is fixed.
112 - autobless has received some attention, resulting in a number of bugs fixed.
113 - Removed mode option as it just caused confusion.
114 - Removed volatile option as it is pretty useless (use locking instead)
115 - Locking now implicitly enables autoflush
117 0.96 Oct 14 09:55:00 2005 Pacific
118 - Fixed build (OS X hidden files killed it)
119 - You can now pass in an optional filehandle to the constructor
121 0.95 Oct 12 13:58:00 2005 Pacific
122 - Added optional autobless flag to preserve and restore blessed hashes
123 - Fixed bug where 0 could not be fetched using get_next_key
124 - Fixed bug where tie() constructor didn't accept a hash ref for args
125 - optimize() now preserves user/group/permissions
126 - Errors are now FATAL (meaning it calls die()), unless you set debug flag
128 0.94 Apr 13 19:00:26 2004 Pacific
129 - Fixed bug reported by John Cardenas (corruption at key level when
130 replace of less data was done on bucket)
132 0.93 Feb 15 19:53:17 2004 Pacific
133 - Fixed optmize() on Win32 where orig file couldn't be overwritten unless
134 filehandle was closed first. This change introduces a potential race
135 condition when using locking and optmize() on Win32, but it can be
136 fixed in the future using a soft copy instead of Perl's rename().
138 0.92 Feb 12 19:10:22 2004 Pacific
139 - Fixed bug where passing a reference to a different DBM::Deep object
140 would still result in an internal reference.
141 - Added export() method for recursively extracting hashes/arrays into
142 standard in-memory Perl structures.
143 - Added import() method for recursively importing existing Perl hash/
145 - Fixed bug where optimize() wouldn't work if base level of DB was
146 an array instead of a hash.
148 0.91 Feb 12 02:30:22 2004 Pacific
149 - Fixed bug with splice() when length of removed section was 0
150 - Updated POD re: circular refs and optimize()
151 - Had to jump version numbers to 0.91 because in previous releases
152 I used only a single digit after the decimal which was confusing
155 0.10 Feb 11 08:58:35 2004 Pacific
156 - Fixed bug where default file mode was CLEARING files (Thanks Rich!)
157 - Added experimental support for circular references
158 - Fixed bugs in shift(), unshift() and splice() where nested objects
159 in array would be recursively re-stored as basic hashes/arrays
160 - Fixed typos in POD docs
162 0.9 Feb 10 03:25:48 2004 Pacific
163 - Added Filters for storing/fetching keys/values
164 - Added hook for supplying own hashing algorithm

167 0.8 Feb 8 02:38:22 2004 Pacific
168 - Renamed to DBM::Deep for CPAN
169 - Added optimize() method for rekindling unused space
170 - Now returning hybrid tie()/OO object from new()
171 - Basic error handling introduced
172 - Added debug mode for printing errors to STDERR
173 - Added TYPE_HASH and TYPE_ARRAY constants for "type" param
174 - Added clone() method for safe copying of objects

183 - Changed file signature to DPDB (not compatible with older versions)
184 - Converted array length to packed long instead of sprintf()ed string
186 0.6 Dec 31 15:12:03 2002 UTC
187 - Some misc optimizations for speed
189 0.5 Oct 18 08:55:29 2002 UTC
190 - support for force_return_next parameter in traverse_index() method for
191 ultra-fast combined key search/removal
193 0.4 Oct 15 20:07:47 2002 UTC
194 - now making sure filehandle is open for all DB calls
196 0.3 Oct 3 19:04:13 2002 UTC
197 - fixed bug that could cause corrupted data when using locking
199 0.2 Aug 6 16:37:32 2002 UTC
200 - Removed base index caching, as it can cause problems when two processes
201 are populating the db at the same time (even with locking)
203 0.1 Jun 3 08:06:26 2002 UTC
