e0fc5922 5 - Fix deep recursion errors (RT#53575)
6 - Avoid leaving temp files lying around (RT#32462)
f696d6ab 7 - (RT #48031) Fixed bug with localized $, (Thanks, SPROUT!)

576320ff 101.0014 Jun 13 23:15:00 2008 EST
11 - (This version is compatible with 1.0013)
12 - Fix for RT#36781 (t/44 has an unrequired dependency)
5c0756fc 13 - lock() has been aliased to lock_exclusive(). There is now
14 a lock_shared() method. The :flock constants are no longer
15 imported into the DBM::Deep namespace.
16 **** THIS IS AN API CHANGE ****

9d3b38e4 181.0013 Jun 13 23:15:00 2008 EST
695c88b1 19 - (This version is compatible with 1.0012)
20 - Fix for RT#30144 (Optimization failure on Win32)
21 - Fixed a bug in reindex_entry (Thanks, Wulfram Humann!)
22
08164b50 231.0012 Jun 09 15:00:00 2008 EST
24 - (This version is compatible with 1.0011)
25 - Fix for RT#30085 (Remove dependency on XS module)
26 - Thank you very much tachyon-II@Perlmonks!!
9d3b38e4 27 - This also resolves RT#35424 (DBM::Deep breaks XML::Twig).
08164b50 28 - Updated the POD with fixes that were made, but still on the TODO list.
29 - Bypass for RT#36419 (t/44_upgrade_db.t fails on *BSD)
30 - We're just going to skip that for now. It's a number-of-processes-open
31 issue. Best is to do a port to another module to do the heavy lifting.
32
331.0011 May 27 15:00:00 2008 EST
34 - (This version is compatible with 1.0010)
35 - A test has the wrong plan.
36
edd45134 371.0010 May 27 12:00:00 2008 EST
b8370759 38 - (This version is compatible with 1.0009)
39 - Fix for RT#35140 (invalid POD links)
edd45134 40 - Fix for RT#34819 (Cannot assign the same value back to the same location)
41 - Fix for RT#29957 (Cannot assign the same value back to the same location)
42 - Fix for RT#33863 (Cannot shift an arrayref from an array)
43 - When something is deleted from a DB, the value is export()ed, allowing it
44 to be saved.
45 - This exporting is only done if the refcount == 0 after the deletion.

6e6789b0 471.0009 Mar 19 12:00:00 2008 EDT
48 - (This version is compatible with 1.0008)
49 - Internal refactorings to prepare for some optimizations.
50 - _fh() has been removed. It was marked as private, so don't complain.
51 - Skip a test that was spuriously failing on Win32 (Thanks, Alias!)
52
45f047f8 531.0008 Mar 09 20:00:00 2008 EDT
54 - (This version is compatible with 1.0007)
55 - Fixed a number of Win32 issues (Reported by Steven Samelson - thank you!)
56 - Much thanks to Nigel Sandever and David Golden for their help
57 debugging the issues, particularly with DBM::Deep's usage of
58 File::Temp (which removes a number of warnings).
59 - Autovivification now works on Win32. It turns out that when a
60 process takes a shared flock on a file, it's not allowed to write to
61 it under Win32, unlike *nix. This is probably a good catch.
62 - Note: The fix is a hack. All locks are now exclusive until a
63 better fix is found.
64
5a70a6c0 651.0007 Jan 10 00:00:00 2008 EDT
66 - (This version is compatible with 1.0006)
67 - Applied a patch+failing test submitted by sprout@cpan.org. Thanks!
68 - Turns out that the case of 17 keys with the same first character in the
69 MD5 hash wasn't being tested for. This was a crashbug.
70 - A fix has been made to upgrade_db.pl (RT# 30067)
71 - The version determinations were in the wrong order or evaluation. This
72 meant that upgrade_db.pl wouldn't work as expected (or at all).
73 - Added a minimum Pod::Usage requirement (RT# 29976)
74 - It's an optional item in Build.PL
75 - utils/upgrade_db.pl now checks for that version, as does the test.
76
e00d0eb3 771.0006 Oct 01 23:15:00 2007 EDT
78 - (This version is compatible with 1.0005)
79 - Removed Clone and replaced it with a hand-written datastructure walker.
80 - This greatly reduces the footprint of a large import
81 - This bypasses a failure of Clone under Perl 5.9.5
82 - Moved t/37_delete_edge_cases.t to t_attic because it wasn't really used
83 - import() has a stricter API now. This is a potentially incompatible API
84 change. Only HASH and ARRAY refs are now allowed and they must match the type
85 of the object being imported into.
86
c57b19c6 871.0005 Oct 01 11:15:00 2007 EDT
88 - (This version is compatible with 1.0004)
89 - Added proper singleton support. This means that the following now works:
90 $db->{foo} = [ 1 .. 3];
91 my $x = $db->{foo};
92 my $y = $db->{foo};
93 is( $x, $y ); # Now passes
94 - This means that Data::Dumper now properly reports when $db->{foo} = $db->{bar}
95
888453b9 961.0004 Sep 28 12:15:00 2007 EDT
97 - (This version is compatible with 1.0003)
98 - Fixed the Changes file (wrong version was displayed for 1.0003)
99 - Added filter sugar methods to be more API-compatible with other DBMs
100 - This was added to support a patch provided to IO::All so it can
101 use DBM::Deep as a DBM provider.
102 - Implemented _dump_file in order to display the file structure. As a
103 result, the following bugs were fixed:
104 - Arrays and hashes now clean up after themselves better.
105 - Bucketlists now clean up after themselves better.
106 - Reindexing properly clears the old bucketlist before freeing it.
107
1081.0003 Sep 24 14:00:00 2007 EDT
1cff45d7 109 - THIS VERSION IS INCOMPATIBLE WITH FILES FROM ALL OTHER PRIOR VERSIONS.
110 - Further fixes for unshift/shift/splice and references (RT# 29583)
111 - To fix that, I had to put support for real references in.
112 - the 16 and 22 tests are now re-enabled.
113 - Yes, this means that real references work. See t/45_references.t
114
807f63a7 1151.0002 Sep 20 22:00:00 2007 EDT
116 - (This version is compatible with 1.0001)
117 - Expanded _throw_error() so that it provides better information.
118 (Thanks brian d foy!)
119 - Fixed how shift, unshift, and splice work when there are references
120 being moved. It now no longer dies.
121 - Added diag in t/17_import.t to note that the failing tests on blead
122 are due to Clone being broken, not DBM::Deep. The tests will still
123 fail because I don't want users to install something that's broken
124 and deal with those bug reports.
125
151e0077 1261.0001 Mar 12 16:15:00 2007 EDT
127 - (This version is compatible with 1.0000)
128 - Added a missing dependency on IO::Scalar (RT #25387)
129 - Fixed how t/44_upgrade_db.t and utils/upgrade_db.pl worked
130 - utils/upgrade_db.pl now uses #!perl, not #!/usr/bin/perl
131 - t/44_upgrade_db.t now explicitly calls $^X
132 (Thanks merlyn!)
133
1341.0000 Feb 26 22:30:00 2007 EST
e9b0b5f0 135 - THIS VERSION IS INCOMPATIBLE WITH FILES FROM ALL OTHER PRIOR VERSIONS.
136 - To aid in this form of upgrades, DBM::Deep now checks the file format
137 version to make sure that it knows how to read it.
138 - db_upgrade.pl was added to utils/. This will -NOT- install onto
139 your system. This is deliberate.
140 - db_upgrade.pl will not handle developer release file formats. This
141 is due to the fact that all developer releases in preparation for a
142 given release share the same file version, even though the file
143 format may change. This is deliberate.
144 - Importing no longer takes place within a transaction
145 - The following parameters were added:
146 - data_sector_size - this determines the default size of a data sector.
147 - Correctly handle opening readonly files
148
151e0077 1490.99_04 Jan 24 22:30:00 2007 EST
2120a181 150 - Added the missing lib/DBM/Deep.pod file to the MANIFEST
151 - Fixed a poorly-designed test that was failing depending on what Clone::Any
e9b0b5f0 152 was using.
2120a181 153 - All "use 5.6.0;" lines are now "use 5.006_000;" to avoid warnings about
e9b0b5f0 154 unsupported vstrings in 5.9.x
2120a181 155
151e0077 1560.99_03 Jan 23 22:30:00 2007 EST
2120a181 157 - THIS VERSION IS INCOMPATIBLE WITH FILES FROM ALL OTHER PRIOR VERSIONS.
158 - The fileformat changed completely. I will be writing a converter, but
159 it's not there right now. Do NOT expect that this module will
160 correctly detect older versions and handle them sanely. Sanity will be
161 there for 1.00, but we're not there yet, are we?
a8fdabda 162 - Converted to use FileHandle::Fmode to handle filehandle status checks
13ff93d5 163 - Fixed bug with deleting already-deleted items on Win32 (reported by Nigel Sandever)
2120a181 164 - The guts of how transactions work has been rewritten to better handle
165 some edgecases. This required a complete rewrite of the engine.
166 - Freespace management is now in place. It's not perfect, but it's there.
167 - The rewrite of the engine required a rewrite of how first_key/next_key
168 was implemented. This should result in significant speed improvements.
169 - Self-reference has been removed. This means you cannot do:
170 $db->{foo} = { x => 'y' };
171 $db->{bar} = $db->{foo};
172 I hope to be able to return this functionality by 1.00, but I cannot
173 promise anything. To do this properly, it requires refcounting in order
174 to correctly handle deletions and transactions. Once you move away from
175 a simple tree, everything becomes really hard.
a8fdabda 176
c8602313 1770.99_02 Apr 28 05:00:00 2006 Pacific
178 - Added missing file to the MANIFEST
179
1800.99_01 Apr 27 18:00:00 2006 Pacific
d2aefba0 181 - Added explicit dependency on Perl 5.6.0
e06824f8 182 - Digest::MD5 requires 5.6.0
183 - Sub::Uplevel (dep of Test::Exception) requires 5.6.0
95967a5e 184 - Removed error()/clear_error()
d2aefba0 185 - All error-handling is done with die()
e06824f8 186 - Broke out DBM::Deep's code into DBM::Deep::Engine
d2aefba0 187 - Tied variables can no longer be assigned to a DBM::Deep object.
188 - This includes cross-file assignments.
189 - Autovivification now works
190 - This is a consequence of the fact that all assignments are tied.
191 - set_pack() and set_digest() have been removed.
192 - Instead, you will now pass the appropriate values into new()
193 - A pack_size parameter has been added to make 64-bit files easier
c8602313 194 - Transactions now work
95967a5e 195
a8fdabda 1960.983 Apr 10 20:00:00 2006 Pacific
197 - Added patch inspired by Jeff Janes (Thanks!)
198 - Autovivification now works correctly
199 - The following now works correctly
200 my %hash = ( a => 1 );
201 $db->{hash} = \%hash;
202 $hash{b} = 2;
203 cmp_ok( $db->{hash}{b}, '==', 2 );
204 - (RT#18530) - DBM::Deep now plays nicely with -l
205
2060.982 Mar 08 11:00:00 2006 Pacific
207 - Fixed smoketests that were failing on Win32
208 - Added restriction for Perl 5.6.0 or higher.
209 - Digest::MD5 and Sub::Uplevel (dep of Test::Exception) require 5.6+
210
2110.981 Mar 06 11:00:00 2006 Pacific
212 - (RT#17947) - Fixed test that was failing on older Perls
213
9be51a89 2140.98 Feb 28 11:00:00 2006 Pacific
a8bd842e 215 - Added in patch by David Cantrell to allow use of DATA filehandle
bcbe5355 216 - Fixed bug where attempting to export() a structure that used autobless would die
e3cb84dc 217 - Fixed arraytest slowness by localizing $SIG{__DIE__} to prevent Test::Builder's
218 $SIG{__DIE__} from being called. (q.v. http://perldoc.perl.org/functions/eval.html)
4d35d856 219 - More methods have been made private:
220 - root() is now _root()
221 - base_offset() is now _base_offset()
222 - fh() is now _fh()
223 - type() is now _type()
224 - precalc_sizes() is now _precalc_sizes()
e3cb84dc 225
6d049f2c 2260.97 Feb 24 10:00:00 2006 Pacific
e096f245 227 - Reorganization of distribution to a more standard layout
ffed8b01 228 - Migration to Module::Build with EU::MM backwards compatibility
e096f245 229 - Migration of all tests to use Test::More and Test::Exception
230 - Added Devel::Cover report to DBM::Deep POD
231 - Test coverage improved to 89.6% (and climbing)
8b957036 232 - The following methods have been renamed to reflect their private nature:
233 - init() is now _init()
14a3acb6 234 - open() is now _open()
0207d648 235 - close() is now _close()
261d1296 236 - load_tag() is now _load_tag()
237 - index_lookup() is now _index_lookup()
238 - add_bucket() is now _add_bucket()
239 - get_bucket_value() is now _get_bucket_value()
240 - delete_bucket() is now _delete_bucket()
241 - bucket_exists() is now _bucket_exists()
242 - find_bucket_list() is now _find_bucket_list()
243 - traverse_index() is now _traverse_index()
244 - get_next_key() is now _get_next_key()
245 - copy_node() is now _copy_node()
246 - throw_error() is now _throw_error()
217fef02 247 - The various tied classes have been broken out. This means that testing
248 "ref( $obj ) eq 'DBM::Deep'" will now fail. The correct test is
249 "eval { $obj->isa( 'DBM::Deep' ) }".
250 - The various methods like push and delete now have the same return values as
251 the standard builtins.
9d085683 252 - TIEARRAY and TIEHASH now check their parameters more thoroughly
e096f245 253 - Negative indices for arrays works as expected, including throwing the appropriate
254 errors.
26138c00 255 - RT #16877 is fixed (DBM::Deep broken with Perl 5.9.3+).
256 - RT #14893 is fixed (tie() and new() use different parameter lists).
257 - A bug with optimize and threading is fixed.
258 - autobless has received some attention, resulting in a number of bugs fixed.
90f93b43 259 - Removed mode option as it just caused confusion.
3ea61317 260 - Removed volatile option as it is pretty useless (use locking instead)
261 - Locking now implicitly enables autoflush
ffed8b01 262
2630.96 Oct 14 09:55:00 2005 Pacific
264 - Fixed build (OS X hidden files killed it)
265 - You can now pass in an optional filehandle to the constructor
266
2670.95 Oct 12 13:58:00 2005 Pacific
268 - Added optional autobless flag to preserve and restore blessed hashes
269 - Fixed bug where 0 could not be fetched using get_next_key
270 - Fixed bug where tie() constructor didn't accept a hash ref for args
271 - optimize() now preserves user/group/permissions
272 - Errors are now FATAL (meaning it calls die()), unless you set debug flag
273
2740.94 Apr 13 19:00:26 2004 Pacific
275 - Fixed bug reported by John Cardenas (corruption at key level when
276 replace of less data was done on bucket)
277
2780.93 Feb 15 19:53:17 2004 Pacific
279 - Fixed optmize() on Win32 where orig file couldn't be overwritten unless
280 filehandle was closed first. This change introduces a potential race
281 condition when using locking and optmize() on Win32, but it can be
282 fixed in the future using a soft copy instead of Perl's rename().
283
2840.92 Feb 12 19:10:22 2004 Pacific
285 - Fixed bug where passing a reference to a different DBM::Deep object
286 would still result in an internal reference.
287 - Added export() method for recursively extracting hashes/arrays into
288 standard in-memory Perl structures.
289 - Added import() method for recursively importing existing Perl hash/
290 array structures
291 - Fixed bug where optimize() wouldn't work if base level of DB was
292 an array instead of a hash.
293
2940.91 Feb 12 02:30:22 2004 Pacific
295 - Fixed bug with splice() when length of removed section was 0
296 - Updated POD re: circular refs and optimize()
297 - Had to jump version numbers to 0.91 because in previous releases
298 I used only a single digit after the decimal which was confusing
299 the CPAN indexer.
300
3010.10 Feb 11 08:58:35 2004 Pacific
302 - Fixed bug where default file mode was CLEARING files (Thanks Rich!)
303 - Added experimental support for circular references
304 - Fixed bugs in shift(), unshift() and splice() where nested objects
305 in array would be recursively re-stored as basic hashes/arrays
306 - Fixed typos in POD docs
307
3080.9 Feb 10 03:25:48 2004 Pacific
309 - Added Filters for storing/fetching keys/values
310 - Added hook for supplying own hashing algorithm
311 - FIxed some typos in POD docs, added new sections
312
3130.8 Feb 8 02:38:22 2004 Pacific
314 - Renamed to DBM::Deep for CPAN
315 - Added optimize() method for rekindling unused space
316 - Now returning hybrid tie()/OO object from new()
317 - Basic error handling introduced
318 - Added debug mode for printing errors to STDERR
319 - Added TYPE_HASH and TYPE_ARRAY constants for "type" param
320 - Added clone() method for safe copying of objects
321 - Wrote POD documentation
322 - Added set_pack() function for manipulating LONG_SIZE / LONG_PACK
323 - Added aliases for most tied functions for public use
324 - Now setting binmode() on FileHandle for Win32
325 - Added 45 unit tests
326
3270.7 Jan 4 11:31:50 2003 UTC
328 - Renamed to DeepDB
329 - Changed file signature to DPDB (not compatible with older versions)
330 - Converted array length to packed long instead of sprintf()ed string
331
3320.6 Dec 31 15:12:03 2002 UTC
333 - Some misc optimizations for speed
334
3350.5 Oct 18 08:55:29 2002 UTC
336 - support for force_return_next parameter in traverse_index() method for
337 ultra-fast combined key search/removal
338
3390.4 Oct 15 20:07:47 2002 UTC
340 - now making sure filehandle is open for all DB calls
341
3420.3 Oct 3 19:04:13 2002 UTC
343 - fixed bug that could cause corrupted data when using locking
344
3450.2 Aug 6 16:37:32 2002 UTC
346 - Removed base index caching, as it can cause problems when two processes
347 are populating the db at the same time (even with locking)
348
3490.1 Jun 3 08:06:26 2002 UTC
350 - initial release
