6e6789b0 31.0009 Mar 19 12:00:00 2008 EDT
4 - (This version is compatible with 1.0008)
5 - Internal refactorings to prepare for some optimizations.
6 - _fh() has been removed. It was marked as private, so don't complain.
7 - Skip a test that was spuriously failing on Win32 (Thanks, Alias!)
8
45f047f8 91.0008 Mar 09 20:00:00 2008 EDT
10 - (This version is compatible with 1.0007)
11 - Fixed a number of Win32 issues (Reported by Steven Samelson - thank you!)
12 - Much thanks to Nigel Sandever and David Golden for their help
13 debugging the issues, particularly with DBM::Deep's usage of
14 File::Temp (which removes a number of warnings).
15 - Autovivification now works on Win32. It turns out that when a
16 process takes a shared flock on a file, it's not allowed to write to
17 it under Win32, unlike *nix. This is probably a good catch.
18 - Note: The fix is a hack. All locks are now exclusive until a
19 better fix is found.
20
5a70a6c0 211.0007 Jan 10 00:00:00 2008 EDT
22 - (This version is compatible with 1.0006)
23 - Applied a patch+failing test submitted by sprout@cpan.org. Thanks!
24 - Turns out that the case of 17 keys with the same first character in the
25 MD5 hash wasn't being tested for. This was a crashbug.
26 - A fix has been made to upgrade_db.pl (RT# 30067)
27 - The version determinations were in the wrong order or evaluation. This
28 meant that upgrade_db.pl wouldn't work as expected (or at all).
29 - Added a minimum Pod::Usage requirement (RT# 29976)
30 - It's an optional item in Build.PL
31 - utils/upgrade_db.pl now checks for that version, as does the test.
32
e00d0eb3 331.0006 Oct 01 23:15:00 2007 EDT
34 - (This version is compatible with 1.0005)
35 - Removed Clone and replaced it with a hand-written datastructure walker.
36 - This greatly reduces the footprint of a large import
37 - This bypasses a failure of Clone under Perl 5.9.5
38 - Moved t/37_delete_edge_cases.t to t_attic because it wasn't really used
39 - import() has a stricter API now. This is a potentially incompatible API
40 change. Only HASH and ARRAY refs are now allowed and they must match the type
41 of the object being imported into.
42
c57b19c6 431.0005 Oct 01 11:15:00 2007 EDT
44 - (This version is compatible with 1.0004)
45 - Added proper singleton support. This means that the following now works:
46 $db->{foo} = [ 1 .. 3];
47 my $x = $db->{foo};
48 my $y = $db->{foo};
49 is( $x, $y ); # Now passes
50 - This means that Data::Dumper now properly reports when $db->{foo} = $db->{bar}
51
888453b9 521.0004 Sep 28 12:15:00 2007 EDT
53 - (This version is compatible with 1.0003)
54 - Fixed the Changes file (wrong version was displayed for 1.0003)
55 - Added filter sugar methods to be more API-compatible with other DBMs
56 - This was added to support a patch provided to IO::All so it can
57 use DBM::Deep as a DBM provider.
58 - Implemented _dump_file in order to display the file structure. As a
59 result, the following bugs were fixed:
60 - Arrays and hashes now clean up after themselves better.
61 - Bucketlists now clean up after themselves better.
62 - Reindexing properly clears the old bucketlist before freeing it.
63
641.0003 Sep 24 14:00:00 2007 EDT
1cff45d7 65 - THIS VERSION IS INCOMPATIBLE WITH FILES FROM ALL OTHER PRIOR VERSIONS.
66 - Further fixes for unshift/shift/splice and references (RT# 29583)
67 - To fix that, I had to put support for real references in.
68 - the 16 and 22 tests are now re-enabled.
69 - Yes, this means that real references work. See t/45_references.t
70
807f63a7 711.0002 Sep 20 22:00:00 2007 EDT
72 - (This version is compatible with 1.0001)
73 - Expanded _throw_error() so that it provides better information.
74 (Thanks brian d foy!)
75 - Fixed how shift, unshift, and splice work when there are references
76 being moved. It now no longer dies.
77 - Added diag in t/17_import.t to note that the failing tests on blead
78 are due to Clone being broken, not DBM::Deep. The tests will still
79 fail because I don't want users to install something that's broken
80 and deal with those bug reports.
81
151e0077 821.0001 Mar 12 16:15:00 2007 EDT
83 - (This version is compatible with 1.0000)
84 - Added a missing dependency on IO::Scalar (RT #25387)
85 - Fixed how t/44_upgrade_db.t and utils/upgrade_db.pl worked
86 - utils/upgrade_db.pl now uses #!perl, not #!/usr/bin/perl
87 - t/44_upgrade_db.t now explicitly calls $^X
88 (Thanks merlyn!)
89
901.0000 Feb 26 22:30:00 2007 EST
e9b0b5f0 91 - THIS VERSION IS INCOMPATIBLE WITH FILES FROM ALL OTHER PRIOR VERSIONS.
92 - To aid in this form of upgrades, DBM::Deep now checks the file format
93 version to make sure that it knows how to read it.
94 - db_upgrade.pl was added to utils/. This will -NOT- install onto
95 your system. This is deliberate.
96 - db_upgrade.pl will not handle developer release file formats. This
97 is due to the fact that all developer releases in preparation for a
98 given release share the same file version, even though the file
99 format may change. This is deliberate.
100 - Importing no longer takes place within a transaction
101 - The following parameters were added:
102 - data_sector_size - this determines the default size of a data sector.
103 - Correctly handle opening readonly files
104
151e0077 1050.99_04 Jan 24 22:30:00 2007 EST
2120a181 106 - Added the missing lib/DBM/Deep.pod file to the MANIFEST
107 - Fixed a poorly-designed test that was failing depending on what Clone::Any
e9b0b5f0 108 was using.
2120a181 109 - All "use 5.6.0;" lines are now "use 5.006_000;" to avoid warnings about
e9b0b5f0 110 unsupported vstrings in 5.9.x
2120a181 111
151e0077 1120.99_03 Jan 23 22:30:00 2007 EST
2120a181 113 - THIS VERSION IS INCOMPATIBLE WITH FILES FROM ALL OTHER PRIOR VERSIONS.
114 - The fileformat changed completely. I will be writing a converter, but
115 it's not there right now. Do NOT expect that this module will
116 correctly detect older versions and handle them sanely. Sanity will be
117 there for 1.00, but we're not there yet, are we?
a8fdabda 118 - Converted to use FileHandle::Fmode to handle filehandle status checks
13ff93d5 119 - Fixed bug with deleting already-deleted items on Win32 (reported by Nigel Sandever)
2120a181 120 - The guts of how transactions work has been rewritten to better handle
121 some edgecases. This required a complete rewrite of the engine.
122 - Freespace management is now in place. It's not perfect, but it's there.
123 - The rewrite of the engine required a rewrite of how first_key/next_key
124 was implemented. This should result in significant speed improvements.
125 - Self-reference has been removed. This means you cannot do:
126 $db->{foo} = { x => 'y' };
127 $db->{bar} = $db->{foo};
128 I hope to be able to return this functionality by 1.00, but I cannot
129 promise anything. To do this properly, it requires refcounting in order
130 to correctly handle deletions and transactions. Once you move away from
131 a simple tree, everything becomes really hard.
a8fdabda 132
c8602313 1330.99_02 Apr 28 05:00:00 2006 Pacific
134 - Added missing file to the MANIFEST
135
1360.99_01 Apr 27 18:00:00 2006 Pacific
d2aefba0 137 - Added explicit dependency on Perl 5.6.0
e06824f8 138 - Digest::MD5 requires 5.6.0
139 - Sub::Uplevel (dep of Test::Exception) requires 5.6.0
95967a5e 140 - Removed error()/clear_error()
d2aefba0 141 - All error-handling is done with die()
e06824f8 142 - Broke out DBM::Deep's code into DBM::Deep::Engine
d2aefba0 143 - Tied variables can no longer be assigned to a DBM::Deep object.
144 - This includes cross-file assignments.
145 - Autovivification now works
146 - This is a consequence of the fact that all assignments are tied.
147 - set_pack() and set_digest() have been removed.
148 - Instead, you will now pass the appropriate values into new()
149 - A pack_size parameter has been added to make 64-bit files easier
c8602313 150 - Transactions now work
95967a5e 151
a8fdabda 1520.983 Apr 10 20:00:00 2006 Pacific
153 - Added patch inspired by Jeff Janes (Thanks!)
154 - Autovivification now works correctly
155 - The following now works correctly
156 my %hash = ( a => 1 );
157 $db->{hash} = \%hash;
158 $hash{b} = 2;
159 cmp_ok( $db->{hash}{b}, '==', 2 );
160 - (RT#18530) - DBM::Deep now plays nicely with -l
161
1620.982 Mar 08 11:00:00 2006 Pacific
163 - Fixed smoketests that were failing on Win32
164 - Added restriction for Perl 5.6.0 or higher.
165 - Digest::MD5 and Sub::Uplevel (dep of Test::Exception) require 5.6+
166
1670.981 Mar 06 11:00:00 2006 Pacific
168 - (RT#17947) - Fixed test that was failing on older Perls
169
9be51a89 1700.98 Feb 28 11:00:00 2006 Pacific
a8bd842e 171 - Added in patch by David Cantrell to allow use of DATA filehandle
bcbe5355 172 - Fixed bug where attempting to export() a structure that used autobless would die
e3cb84dc 173 - Fixed arraytest slowness by localizing $SIG{__DIE__} to prevent Test::Builder's
174 $SIG{__DIE__} from being called. (q.v. http://perldoc.perl.org/functions/eval.html)
4d35d856 175 - More methods have been made private:
176 - root() is now _root()
177 - base_offset() is now _base_offset()
178 - fh() is now _fh()
179 - type() is now _type()
180 - precalc_sizes() is now _precalc_sizes()
e3cb84dc 181
6d049f2c 1820.97 Feb 24 10:00:00 2006 Pacific
e096f245 183 - Reorganization of distribution to a more standard layout
ffed8b01 184 - Migration to Module::Build with EU::MM backwards compatibility
e096f245 185 - Migration of all tests to use Test::More and Test::Exception
186 - Added Devel::Cover report to DBM::Deep POD
187 - Test coverage improved to 89.6% (and climbing)
8b957036 188 - The following methods have been renamed to reflect their private nature:
189 - init() is now _init()
14a3acb6 190 - open() is now _open()
0207d648 191 - close() is now _close()
261d1296 192 - load_tag() is now _load_tag()
193 - index_lookup() is now _index_lookup()
194 - add_bucket() is now _add_bucket()
195 - get_bucket_value() is now _get_bucket_value()
196 - delete_bucket() is now _delete_bucket()
197 - bucket_exists() is now _bucket_exists()
198 - find_bucket_list() is now _find_bucket_list()
199 - traverse_index() is now _traverse_index()
200 - get_next_key() is now _get_next_key()
201 - copy_node() is now _copy_node()
202 - throw_error() is now _throw_error()
217fef02 203 - The various tied classes have been broken out. This means that testing
204 "ref( $obj ) eq 'DBM::Deep'" will now fail. The correct test is
205 "eval { $obj->isa( 'DBM::Deep' ) }".
206 - The various methods like push and delete now have the same return values as
207 the standard builtins.
9d085683 208 - TIEARRAY and TIEHASH now check their parameters more thoroughly
e096f245 209 - Negative indices for arrays works as expected, including throwing the appropriate
210 errors.
26138c00 211 - RT #16877 is fixed (DBM::Deep broken with Perl 5.9.3+).
212 - RT #14893 is fixed (tie() and new() use different parameter lists).
213 - A bug with optimize and threading is fixed.
214 - autobless has received some attention, resulting in a number of bugs fixed.
90f93b43 215 - Removed mode option as it just caused confusion.
3ea61317 216 - Removed volatile option as it is pretty useless (use locking instead)
217 - Locking now implicitly enables autoflush
ffed8b01 218
2190.96 Oct 14 09:55:00 2005 Pacific
220 - Fixed build (OS X hidden files killed it)
221 - You can now pass in an optional filehandle to the constructor
222
2230.95 Oct 12 13:58:00 2005 Pacific
224 - Added optional autobless flag to preserve and restore blessed hashes
225 - Fixed bug where 0 could not be fetched using get_next_key
226 - Fixed bug where tie() constructor didn't accept a hash ref for args
227 - optimize() now preserves user/group/permissions
228 - Errors are now FATAL (meaning it calls die()), unless you set debug flag
229
2300.94 Apr 13 19:00:26 2004 Pacific
231 - Fixed bug reported by John Cardenas (corruption at key level when
232 replace of less data was done on bucket)
233
2340.93 Feb 15 19:53:17 2004 Pacific
235 - Fixed optmize() on Win32 where orig file couldn't be overwritten unless
236 filehandle was closed first. This change introduces a potential race
237 condition when using locking and optmize() on Win32, but it can be
238 fixed in the future using a soft copy instead of Perl's rename().
239
2400.92 Feb 12 19:10:22 2004 Pacific
241 - Fixed bug where passing a reference to a different DBM::Deep object
242 would still result in an internal reference.
243 - Added export() method for recursively extracting hashes/arrays into
244 standard in-memory Perl structures.
245 - Added import() method for recursively importing existing Perl hash/
246 array structures
247 - Fixed bug where optimize() wouldn't work if base level of DB was
248 an array instead of a hash.
249
2500.91 Feb 12 02:30:22 2004 Pacific
251 - Fixed bug with splice() when length of removed section was 0
252 - Updated POD re: circular refs and optimize()
253 - Had to jump version numbers to 0.91 because in previous releases
254 I used only a single digit after the decimal which was confusing
255 the CPAN indexer.
256
2570.10 Feb 11 08:58:35 2004 Pacific
258 - Fixed bug where default file mode was CLEARING files (Thanks Rich!)
259 - Added experimental support for circular references
260 - Fixed bugs in shift(), unshift() and splice() where nested objects
261 in array would be recursively re-stored as basic hashes/arrays
262 - Fixed typos in POD docs
263
2640.9 Feb 10 03:25:48 2004 Pacific
265 - Added Filters for storing/fetching keys/values
266 - Added hook for supplying own hashing algorithm
267 - FIxed some typos in POD docs, added new sections
268
2690.8 Feb 8 02:38:22 2004 Pacific
270 - Renamed to DBM::Deep for CPAN
271 - Added optimize() method for rekindling unused space
272 - Now returning hybrid tie()/OO object from new()
273 - Basic error handling introduced
274 - Added debug mode for printing errors to STDERR
275 - Added TYPE_HASH and TYPE_ARRAY constants for "type" param
276 - Added clone() method for safe copying of objects
277 - Wrote POD documentation
278 - Added set_pack() function for manipulating LONG_SIZE / LONG_PACK
279 - Added aliases for most tied functions for public use
280 - Now setting binmode() on FileHandle for Win32
281 - Added 45 unit tests
282
2830.7 Jan 4 11:31:50 2003 UTC
284 - Renamed to DeepDB
285 - Changed file signature to DPDB (not compatible with older versions)
286 - Converted array length to packed long instead of sprintf()ed string
287
2880.6 Dec 31 15:12:03 2002 UTC
289 - Some misc optimizations for speed
290
2910.5 Oct 18 08:55:29 2002 UTC
292 - support for force_return_next parameter in traverse_index() method for
293 ultra-fast combined key search/removal
294
2950.4 Oct 15 20:07:47 2002 UTC
296 - now making sure filehandle is open for all DB calls
297
2980.3 Oct 3 19:04:13 2002 UTC
299 - fixed bug that could cause corrupted data when using locking
300
3010.2 Aug 6 16:37:32 2002 UTC
302 - Removed base index caching, as it can cause problems when two processes
303 are populating the db at the same time (even with locking)
304
3050.1 Jun 3 08:06:26 2002 UTC
306 - initial release
