2
7447c77c 31.0000 Feb 26 22:30:00 2007 EDT
811224a0 4 - THIS VERSION IS INCOMPATIBLE WITH FILES FROM ALL OTHER PRIOR VERSIONS.
5 - To aid in this form of upgrades, DBM::Deep now checks the file format
6 version to make sure that it knows how to read it.
7447c77c 7 - db_upgrade.pl was added to utils/. This will -NOT- install onto
8 your system. This is deliberate.
9 - db_upgrade.pl will not handle developer release file formats. This
10 is due to the fact that all developer releases in preparation for a
11 given release share the same file version, even though the file
12 format may change. This is deliberate.
13 - Importing no longer takes place within a transaction
811224a0 14 - The following parameters were added:
15 - data_sector_size - this determines the default size of a data sector.
7447c77c 16 - Correctly handle opening readonly files
811224a0 17
0ee72d65 180.99_04 Jan 24 22:30:00 2007 EDT
19 - Added the missing lib/DBM/Deep.pod file to the MANIFEST
20 - Fixed a poorly-designed test that was failing depending on what Clone::Any
811224a0 21 was using.
0ee72d65 22 - All "use 5.6.0;" lines are now "use 5.006_000;" to avoid warnings about
811224a0 23 unsupported vstrings in 5.9.x

250.99_03 Jan 23 22:30:00 2007 EDT
7645a22a 26 - THIS VERSION IS INCOMPATIBLE WITH FILES FROM ALL OTHER PRIOR VERSIONS.
27 - The fileformat changed completely. I will be writing a converter, but
28 it's not there right now. Do NOT expect that this module will
29 correctly detect older versions and handle them sanely. Sanity will be
30 there for 1.00, but we're not there yet, are we?
a8fdabda 31 - Converted to use FileHandle::Fmode to handle filehandle status checks
13ff93d5 32 - Fixed bug with deleting already-deleted items on Win32 (reported by Nigel Sandever)
7645a22a 33 - The guts of how transactions work has been rewritten to better handle
34 some edgecases. This required a complete rewrite of the engine.
35 - Freespace management is now in place. It's not perfect, but it's there.
36 - The rewrite of the engine required a rewrite of how first_key/next_key
37 was implemented. This should result in significant speed improvements.
38 - Self-reference has been removed. This means you cannot do:
39 $db->{foo} = { x => 'y' };
40 $db->{bar} = $db->{foo};
41 I hope to be able to return this functionality by 1.00, but I cannot
42 promise anything. To do this properly, it requires refcounting in order
43 to correctly handle deletions and transactions. Once you move away from
44 a simple tree, everything becomes really hard.

c8602313 460.99_02 Apr 28 05:00:00 2006 Pacific
47 - Added missing file to the MANIFEST
48
490.99_01 Apr 27 18:00:00 2006 Pacific
d2aefba0 50 - Added explicit dependency on Perl 5.6.0
e06824f8 51 - Digest::MD5 requires 5.6.0
52 - Sub::Uplevel (dep of Test::Exception) requires 5.6.0
95967a5e 53 - Removed error()/clear_error()
d2aefba0 54 - All error-handling is done with die()
e06824f8 55 - Broke out DBM::Deep's code into DBM::Deep::Engine
d2aefba0 56 - Tied variables can no longer be assigned to a DBM::Deep object.
57 - This includes cross-file assignments.
58 - Autovivification now works
59 - This is a consequence of the fact that all assignments are tied.
60 - set_pack() and set_digest() have been removed.
61 - Instead, you will now pass the appropriate values into new()
62 - A pack_size parameter has been added to make 64-bit files easier
c8602313 63 - Transactions now work
95967a5e 64
a8fdabda 650.983 Apr 10 20:00:00 2006 Pacific
66 - Added patch inspired by Jeff Janes (Thanks!)
67 - Autovivification now works correctly
68 - The following now works correctly
69 my %hash = ( a => 1 );
70 $db->{hash} = \%hash;
71 $hash{b} = 2;
72 cmp_ok( $db->{hash}{b}, '==', 2 );
73 - (RT#18530) - DBM::Deep now plays nicely with -l
74
750.982 Mar 08 11:00:00 2006 Pacific
76 - Fixed smoketests that were failing on Win32
77 - Added restriction for Perl 5.6.0 or higher.

82
9be51a89 830.98 Feb 28 11:00:00 2006 Pacific
a8bd842e 84 - Added in patch by David Cantrell to allow use of DATA filehandle
bcbe5355 85 - Fixed bug where attempting to export() a structure that used autobless would die
e3cb84dc 86 - Fixed arraytest slowness by localizing $SIG{__DIE__} to prevent Test::Builder's
87 $SIG{__DIE__} from being called. (q.v. http://perldoc.perl.org/functions/eval.html)
4d35d856 88 - More methods have been made private:
89 - root() is now _root()

e096f245 98 - Migration of all tests to use Test::More and Test::Exception
99 - Added Devel::Cover report to DBM::Deep POD
100 - Test coverage improved to 89.6% (and climbing)
8b957036 101 - The following methods have been renamed to reflect their private nature:
102 - init() is now _init()
14a3acb6 103 - open() is now _open()
0207d648 104 - close() is now _close()
261d1296 105 - load_tag() is now _load_tag()
106 - index_lookup() is now _index_lookup()
107 - add_bucket() is now _add_bucket()
108 - get_bucket_value() is now _get_bucket_value()
109 - delete_bucket() is now _delete_bucket()
110 - bucket_exists() is now _bucket_exists()
111 - find_bucket_list() is now _find_bucket_list()
112 - traverse_index() is now _traverse_index()
113 - get_next_key() is now _get_next_key()
114 - copy_node() is now _copy_node()
115 - throw_error() is now _throw_error()
217fef02 116 - The various tied classes have been broken out. This means that testing
117 "ref( $obj ) eq 'DBM::Deep'" will now fail. The correct test is
118 "eval { $obj->isa( 'DBM::Deep' ) }".
119 - The various methods like push and delete now have the same return values as
120 the standard builtins.
9d085683 121 - TIEARRAY and TIEHASH now check their parameters more thoroughly
e096f245 122 - Negative indices for arrays works as expected, including throwing the appropriate
123 errors.
26138c00 124 - RT #16877 is fixed (DBM::Deep broken with Perl 5.9.3+).
125 - RT #14893 is fixed (tie() and new() use different parameter lists).
126 - A bug with optimize and threading is fixed.
127 - autobless has received some attention, resulting in a number of bugs fixed.
90f93b43 128 - Removed mode option as it just caused confusion.
3ea61317 129 - Removed volatile option as it is pretty useless (use locking instead)
130 - Locking now implicitly enables autoflush
ffed8b01 131
1320.96 Oct 14 09:55:00 2005 Pacific
133 - Fixed build (OS X hidden files killed it)
134 - You can now pass in an optional filehandle to the constructor
135
1360.95 Oct 12 13:58:00 2005 Pacific
137 - Added optional autobless flag to preserve and restore blessed hashes
138 - Fixed bug where 0 could not be fetched using get_next_key
139 - Fixed bug where tie() constructor didn't accept a hash ref for args
140 - optimize() now preserves user/group/permissions
141 - Errors are now FATAL (meaning it calls die()), unless you set debug flag
142
1430.94 Apr 13 19:00:26 2004 Pacific
144 - Fixed bug reported by John Cardenas (corruption at key level when
145 replace of less data was done on bucket)
146
1470.93 Feb 15 19:53:17 2004 Pacific
148 - Fixed optmize() on Win32 where orig file couldn't be overwritten unless
149 filehandle was closed first. This change introduces a potential race
150 condition when using locking and optmize() on Win32, but it can be
151 fixed in the future using a soft copy instead of Perl's rename().
152
1530.92 Feb 12 19:10:22 2004 Pacific
154 - Fixed bug where passing a reference to a different DBM::Deep object
155 would still result in an internal reference.
156 - Added export() method for recursively extracting hashes/arrays into
157 standard in-memory Perl structures.
158 - Added import() method for recursively importing existing Perl hash/
159 array structures
160 - Fixed bug where optimize() wouldn't work if base level of DB was
161 an array instead of a hash.
162
1630.91 Feb 12 02:30:22 2004 Pacific
164 - Fixed bug with splice() when length of removed section was 0
165 - Updated POD re: circular refs and optimize()
166 - Had to jump version numbers to 0.91 because in previous releases
167 I used only a single digit after the decimal which was confusing
168 the CPAN indexer.
169
1700.10 Feb 11 08:58:35 2004 Pacific
171 - Fixed bug where default file mode was CLEARING files (Thanks Rich!)
172 - Added experimental support for circular references
173 - Fixed bugs in shift(), unshift() and splice() where nested objects
174 in array would be recursively re-stored as basic hashes/arrays
175 - Fixed typos in POD docs
176
1770.9 Feb 10 03:25:48 2004 Pacific
178 - Added Filters for storing/fetching keys/values
179 - Added hook for supplying own hashing algorithm
180 - FIxed some typos in POD docs, added new sections
181
1820.8 Feb 8 02:38:22 2004 Pacific
183 - Renamed to DBM::Deep for CPAN
184 - Added optimize() method for rekindling unused space
185 - Now returning hybrid tie()/OO object from new()
186 - Basic error handling introduced
187 - Added debug mode for printing errors to STDERR
188 - Added TYPE_HASH and TYPE_ARRAY constants for "type" param
189 - Added clone() method for safe copying of objects
190 - Wrote POD documentation
191 - Added set_pack() function for manipulating LONG_SIZE / LONG_PACK
192 - Added aliases for most tied functions for public use
193 - Now setting binmode() on FileHandle for Win32
194 - Added 45 unit tests
195
1960.7 Jan 4 11:31:50 2003 UTC
197 - Renamed to DeepDB
198 - Changed file signature to DPDB (not compatible with older versions)
199 - Converted array length to packed long instead of sprintf()ed string
200
2010.6 Dec 31 15:12:03 2002 UTC
202 - Some misc optimizations for speed
203
2040.5 Oct 18 08:55:29 2002 UTC
205 - support for force_return_next parameter in traverse_index() method for
206 ultra-fast combined key search/removal
207
2080.4 Oct 15 20:07:47 2002 UTC
209 - now making sure filehandle is open for all DB calls
210
2110.3 Oct 3 19:04:13 2002 UTC
212 - fixed bug that could cause corrupted data when using locking
213
2140.2 Aug 6 16:37:32 2002 UTC
215 - Removed base index caching, as it can cause problems when two processes
216 are populating the db at the same time (even with locking)
217
2180.1 Jun 3 08:06:26 2002 UTC
219 - initial release
