3 | 1.0019_001 Dec 31 22:00:00 2009 EST |
4 | (This is the first developer release for 1.0020.) |
5 | (This version is compatible with 1.0014) |
6 | - DBM::Deep has been refactored to allow for multiple engines. There are two |
7 | engines built so far: |
8 | - File (the original engine) |
9 | - DBI (an engine based on DBI) |
10 | - The DBI engine has only been tested on MySQL and isn't transactional. |
11 | - InnoDB sucks horribly. When run in a sufficient isolation mode, it |
12 | creates deadlocks. |
13 | - A custom Build.PL has been written to allow for running tests under |
14 | CPAN.pm against the various engines. |
15 | - This also allows running the long tests under CPAN.pm |
16 | - This has meant a ton of refactoring. Hopefullly, this refactoring will |
17 | allow finding some of the niggly bugs more easily. Those tests have not |
18 | been enabled yet. That's the next developer release. |
19 | - Hopefully, this multi-engine support will allow deprecation of the file |
20 | format in the future. |

22 | 1.0014 Jun 13 23:15:00 2008 EST |
23 | - (This version is compatible with 1.0013) |
24 | - Fix for RT#36781 (t/44 has an unrequired dependency) |
5c0756fc |
25 | - lock() has been aliased to lock_exclusive(). There is now |
26 | a lock_shared() method. The :flock constants are no longer |
27 | imported into the DBM::Deep namespace. |
28 | **** THIS IS AN API CHANGE **** |

30 | 1.0013 Jun 13 23:15:00 2008 EST |
695c88b1 |
31 | - (This version is compatible with 1.0012) |
32 | - Fix for RT#30144 (Optimization failure on Win32) |
33 | - Fixed a bug in reindex_entry (Thanks, Wulfram Humann!) |
34 | |

35 | 1.0012 Jun 09 15:00:00 2008 EST |
36 | - (This version is compatible with 1.0011) |
37 | - Fix for RT#30085 (Remove dependency on XS module) |
38 | - Thank you very much tachyon-II@Perlmonks!! |
9d3b38e4 |
39 | - This also resolves RT#35424 (DBM::Deep breaks XML::Twig). |
08164b50 |
40 | - Updated the POD with fixes that were made, but still on the TODO list. |
41 | - Bypass for RT#36419 (t/44_upgrade_db.t fails on *BSD) |
42 | - We're just going to skip that for now. It's a number-of-processes-open |
43 | issue. Best is to do a port to another module to do the heavy lifting. |
44 | |
45 | 1.0011 May 27 15:00:00 2008 EST |
46 | - (This version is compatible with 1.0010) |
47 | - A test has the wrong plan. |

49 | 1.0010 May 27 12:00:00 2008 EST |
b8370759 |
50 | - (This version is compatible with 1.0009) |
51 | - Fix for RT#35140 (invalid POD links) |
edd45134 |
52 | - Fix for RT#34819 (Cannot assign the same value back to the same location) |
53 | - Fix for RT#29957 (Cannot assign the same value back to the same location) |
54 | - Fix for RT#33863 (Cannot shift an arrayref from an array) |
55 | - When something is deleted from a DB, the value is export()ed, allowing it |
56 | to be saved. |
57 | - This exporting is only done if the refcount == 0 after the deletion. |

59 | 1.0009 Mar 19 12:00:00 2008 EDT |
60 | - (This version is compatible with 1.0008) |
61 | - Internal refactorings to prepare for some optimizations. |
62 | - _fh() has been removed. It was marked as private, so don't complain. |
63 | - Skip a test that was spuriously failing on Win32 (Thanks, Alias!) |
64 | |
45f047f8 |
65 | 1.0008 Mar 09 20:00:00 2008 EDT |
66 | - (This version is compatible with 1.0007) |
67 | - Fixed a number of Win32 issues (Reported by Steven Samelson - thank you!) |
68 | - Much thanks to Nigel Sandever and David Golden for their help |
69 | debugging the issues, particularly with DBM::Deep's usage of |
70 | File::Temp (which removes a number of warnings). |
71 | - Autovivification now works on Win32. It turns out that when a |
72 | process takes a shared flock on a file, it's not allowed to write to |
73 | it under Win32, unlike *nix. This is probably a good catch. |
74 | - Note: The fix is a hack. All locks are now exclusive until a |
75 | better fix is found. |
76 | |

77 | 1.0007 Jan 10 00:00:00 2008 EDT |
78 | - (This version is compatible with 1.0006) |
79 | - Applied a patch+failing test submitted by sprout@cpan.org. Thanks! |
80 | - Turns out that the case of 17 keys with the same first character in the |
81 | MD5 hash wasn't being tested for. This was a crashbug. |
82 | - A fix has been made to upgrade_db.pl (RT# 30067) |
83 | - The version determinations were in the wrong order or evaluation. This |
84 | meant that upgrade_db.pl wouldn't work as expected (or at all). |
85 | - Added a minimum Pod::Usage requirement (RT# 29976) |
86 | - It's an optional item in Build.PL |
87 | - utils/upgrade_db.pl now checks for that version, as does the test. |
88 | |

89 | 1.0006 Oct 01 23:15:00 2007 EDT |
90 | - (This version is compatible with 1.0005) |
91 | - Removed Clone and replaced it with a hand-written datastructure walker. |
92 | - This greatly reduces the footprint of a large import |
93 | - This bypasses a failure of Clone under Perl 5.9.5 |
94 | - Moved t/37_delete_edge_cases.t to t_attic because it wasn't really used |
95 | - import() has a stricter API now. This is a potentially incompatible API |
96 | change. Only HASH and ARRAY refs are now allowed and they must match the type |
97 | of the object being imported into. |
98 | |

99 | 1.0005 Oct 01 11:15:00 2007 EDT |
100 | - (This version is compatible with 1.0004) |
101 | - Added proper singleton support. This means that the following now works: |
102 | $db->{foo} = [ 1 .. 3]; |
103 | my $x = $db->{foo}; |
104 | my $y = $db->{foo}; |
105 | is( $x, $y ); # Now passes |
106 | - This means that Data::Dumper now properly reports when $db->{foo} = $db->{bar} |
107 | |
888453b9 |
108 | 1.0004 Sep 28 12:15:00 2007 EDT |
109 | - (This version is compatible with 1.0003) |
110 | - Fixed the Changes file (wrong version was displayed for 1.0003) |
111 | - Added filter sugar methods to be more API-compatible with other DBMs |
112 | - This was added to support a patch provided to IO::All so it can |
113 | use DBM::Deep as a DBM provider. |
114 | - Implemented _dump_file in order to display the file structure. As a |
115 | result, the following bugs were fixed: |
116 | - Arrays and hashes now clean up after themselves better. |
117 | - Bucketlists now clean up after themselves better. |
118 | - Reindexing properly clears the old bucketlist before freeing it. |
119 | |
120 | 1.0003 Sep 24 14:00:00 2007 EDT |
1cff45d7 |
121 | - THIS VERSION IS INCOMPATIBLE WITH FILES FROM ALL OTHER PRIOR VERSIONS. |
122 | - Further fixes for unshift/shift/splice and references (RT# 29583) |
123 | - To fix that, I had to put support for real references in. |
124 | - the 16 and 22 tests are now re-enabled. |
125 | - Yes, this means that real references work. See t/45_references.t |
126 | |
807f63a7 |
127 | 1.0002 Sep 20 22:00:00 2007 EDT |
128 | - (This version is compatible with 1.0001) |
129 | - Expanded _throw_error() so that it provides better information. |
130 | (Thanks brian d foy!) |
131 | - Fixed how shift, unshift, and splice work when there are references |
132 | being moved. It now no longer dies. |
133 | - Added diag in t/17_import.t to note that the failing tests on blead |
134 | are due to Clone being broken, not DBM::Deep. The tests will still |
135 | fail because I don't want users to install something that's broken |
136 | and deal with those bug reports. |
137 | |
151e0077 |
138 | 1.0001 Mar 12 16:15:00 2007 EDT |
139 | - (This version is compatible with 1.0000) |
140 | - Added a missing dependency on IO::Scalar (RT #25387) |
141 | - Fixed how t/44_upgrade_db.t and utils/upgrade_db.pl worked |
142 | - utils/upgrade_db.pl now uses #!perl, not #!/usr/bin/perl |
143 | - t/44_upgrade_db.t now explicitly calls $^X |
144 | (Thanks merlyn!) |
145 | |
146 | 1.0000 Feb 26 22:30:00 2007 EST |
e9b0b5f0 |
147 | - THIS VERSION IS INCOMPATIBLE WITH FILES FROM ALL OTHER PRIOR VERSIONS. |
148 | - To aid in this form of upgrades, DBM::Deep now checks the file format |
149 | version to make sure that it knows how to read it. |
150 | - db_upgrade.pl was added to utils/. This will -NOT- install onto |
151 | your system. This is deliberate. |
152 | - db_upgrade.pl will not handle developer release file formats. This |
153 | is due to the fact that all developer releases in preparation for a |
154 | given release share the same file version, even though the file |
155 | format may change. This is deliberate. |
156 | - Importing no longer takes place within a transaction |
157 | - The following parameters were added: |
158 | - data_sector_size - this determines the default size of a data sector. |
159 | - Correctly handle opening readonly files |
160 | |
151e0077 |
161 | 0.99_04 Jan 24 22:30:00 2007 EST |
2120a181 |
162 | - Added the missing lib/DBM/Deep.pod file to the MANIFEST |
163 | - Fixed a poorly-designed test that was failing depending on what Clone::Any |
e9b0b5f0 |
164 | was using. |
2120a181 |
165 | - All "use 5.6.0;" lines are now "use 5.006_000;" to avoid warnings about |
e9b0b5f0 |
166 | unsupported vstrings in 5.9.x |
2120a181 |
167 | |

168 | 0.99_03 Jan 23 22:30:00 2007 EST |
2120a181 |
169 | - THIS VERSION IS INCOMPATIBLE WITH FILES FROM ALL OTHER PRIOR VERSIONS. |
170 | - The fileformat changed completely. I will be writing a converter, but |
171 | it's not there right now. Do NOT expect that this module will |
172 | correctly detect older versions and handle them sanely. Sanity will be |
173 | there for 1.00, but we're not there yet, are we? |
a8fdabda |
174 | - Converted to use FileHandle::Fmode to handle filehandle status checks |
13ff93d5 |
175 | - Fixed bug with deleting already-deleted items on Win32 (reported by Nigel Sandever) |
2120a181 |
176 | - The guts of how transactions work has been rewritten to better handle |
177 | some edgecases. This required a complete rewrite of the engine. |
178 | - Freespace management is now in place. It's not perfect, but it's there. |
179 | - The rewrite of the engine required a rewrite of how first_key/next_key |
180 | was implemented. This should result in significant speed improvements. |
181 | - Self-reference has been removed. This means you cannot do: |
182 | $db->{foo} = { x => 'y' }; |
183 | $db->{bar} = $db->{foo}; |
184 | I hope to be able to return this functionality by 1.00, but I cannot |
185 | promise anything. To do this properly, it requires refcounting in order |
186 | to correctly handle deletions and transactions. Once you move away from |
187 | a simple tree, everything becomes really hard. |

189 | 0.99_02 Apr 28 05:00:00 2006 Pacific |
190 | - Added missing file to the MANIFEST |
191 | |
192 | 0.99_01 Apr 27 18:00:00 2006 Pacific |
d2aefba0 |
193 | - Added explicit dependency on Perl 5.6.0 |
e06824f8 |
194 | - Digest::MD5 requires 5.6.0 |
195 | - Sub::Uplevel (dep of Test::Exception) requires 5.6.0 |
95967a5e |
196 | - Removed error()/clear_error() |
d2aefba0 |
197 | - All error-handling is done with die() |
e06824f8 |
198 | - Broke out DBM::Deep's code into DBM::Deep::Engine |
d2aefba0 |
199 | - Tied variables can no longer be assigned to a DBM::Deep object. |
200 | - This includes cross-file assignments. |
201 | - Autovivification now works |
202 | - This is a consequence of the fact that all assignments are tied. |
203 | - set_pack() and set_digest() have been removed. |
204 | - Instead, you will now pass the appropriate values into new() |
205 | - A pack_size parameter has been added to make 64-bit files easier |
c8602313 |
206 | - Transactions now work |
95967a5e |
207 | |
a8fdabda |
208 | 0.983 Apr 10 20:00:00 2006 Pacific |
209 | - Added patch inspired by Jeff Janes (Thanks!) |
210 | - Autovivification now works correctly |
211 | - The following now works correctly |
212 | my %hash = ( a => 1 ); |
213 | $db->{hash} = \%hash; |
214 | $hash{b} = 2; |
215 | cmp_ok( $db->{hash}{b}, '==', 2 ); |
216 | - (RT#18530) - DBM::Deep now plays nicely with -l |
217 | |
218 | 0.982 Mar 08 11:00:00 2006 Pacific |
219 | - Fixed smoketests that were failing on Win32 |
220 | - Added restriction for Perl 5.6.0 or higher. |
221 | - Digest::MD5 and Sub::Uplevel (dep of Test::Exception) require 5.6+ |
222 | |
223 | 0.981 Mar 06 11:00:00 2006 Pacific |
224 | - (RT#17947) - Fixed test that was failing on older Perls |
225 | |
9be51a89 |
226 | 0.98 Feb 28 11:00:00 2006 Pacific |
a8bd842e |
227 | - Added in patch by David Cantrell to allow use of DATA filehandle |
bcbe5355 |
228 | - Fixed bug where attempting to export() a structure that used autobless would die |
e3cb84dc |
229 | - Fixed arraytest slowness by localizing $SIG{__DIE__} to prevent Test::Builder's |
230 | $SIG{__DIE__} from being called. (q.v. http://perldoc.perl.org/functions/eval.html) |
4d35d856 |
231 | - More methods have been made private: |
232 | - root() is now _root() |
233 | - base_offset() is now _base_offset() |
234 | - fh() is now _fh() |
235 | - type() is now _type() |
236 | - precalc_sizes() is now _precalc_sizes() |
e3cb84dc |

6d049f2c |
238 | 0.97 Feb 24 10:00:00 2006 Pacific |
e096f245 |
239 | - Reorganization of distribution to a more standard layout |
ffed8b01 |
240 | - Migration to Module::Build with EU::MM backwards compatibility |
e096f245 |
241 | - Migration of all tests to use Test::More and Test::Exception |
242 | - Added Devel::Cover report to DBM::Deep POD |
243 | - Test coverage improved to 89.6% (and climbing) |
8b957036 |
244 | - The following methods have been renamed to reflect their private nature: |
245 | - init() is now _init() |
14a3acb6 |
246 | - open() is now _open() |
0207d648 |
247 | - close() is now _close() |
261d1296 |
248 | - load_tag() is now _load_tag() |
249 | - index_lookup() is now _index_lookup() |
250 | - add_bucket() is now _add_bucket() |
251 | - get_bucket_value() is now _get_bucket_value() |
252 | - delete_bucket() is now _delete_bucket() |
253 | - bucket_exists() is now _bucket_exists() |
254 | - find_bucket_list() is now _find_bucket_list() |
255 | - traverse_index() is now _traverse_index() |
256 | - get_next_key() is now _get_next_key() |
257 | - copy_node() is now _copy_node() |
258 | - throw_error() is now _throw_error() |
217fef02 |
259 | - The various tied classes have been broken out. This means that testing |
260 | "ref( $obj ) eq 'DBM::Deep'" will now fail. The correct test is |
261 | "eval { $obj->isa( 'DBM::Deep' ) }". |
262 | - The various methods like push and delete now have the same return values as |
263 | the standard builtins. |
9d085683 |
264 | - TIEARRAY and TIEHASH now check their parameters more thoroughly |
e096f245 |
265 | - Negative indices for arrays works as expected, including throwing the appropriate |
266 | errors. |
26138c00 |
267 | - RT #16877 is fixed (DBM::Deep broken with Perl 5.9.3+). |
268 | - RT #14893 is fixed (tie() and new() use different parameter lists). |
269 | - A bug with optimize and threading is fixed. |
270 | - autobless has received some attention, resulting in a number of bugs fixed. |
90f93b43 |
271 | - Removed mode option as it just caused confusion. |
3ea61317 |
272 | - Removed volatile option as it is pretty useless (use locking instead) |
273 | - Locking now implicitly enables autoflush |
ffed8b01 |
274 | |
275 | 0.96 Oct 14 09:55:00 2005 Pacific |
276 | - Fixed build (OS X hidden files killed it) |
277 | - You can now pass in an optional filehandle to the constructor |
278 | |
279 | 0.95 Oct 12 13:58:00 2005 Pacific |
280 | - Added optional autobless flag to preserve and restore blessed hashes |
281 | - Fixed bug where 0 could not be fetched using get_next_key |
282 | - Fixed bug where tie() constructor didn't accept a hash ref for args |
283 | - optimize() now preserves user/group/permissions |
284 | - Errors are now FATAL (meaning it calls die()), unless you set debug flag |
285 | |
286 | 0.94 Apr 13 19:00:26 2004 Pacific |
287 | - Fixed bug reported by John Cardenas (corruption at key level when |
288 | replace of less data was done on bucket) |
289 | |
290 | 0.93 Feb 15 19:53:17 2004 Pacific |
291 | - Fixed optmize() on Win32 where orig file couldn't be overwritten unless |
292 | filehandle was closed first. This change introduces a potential race |
293 | condition when using locking and optmize() on Win32, but it can be |
294 | fixed in the future using a soft copy instead of Perl's rename(). |
295 | |
296 | 0.92 Feb 12 19:10:22 2004 Pacific |
297 | - Fixed bug where passing a reference to a different DBM::Deep object |
298 | would still result in an internal reference. |
299 | - Added export() method for recursively extracting hashes/arrays into |
300 | standard in-memory Perl structures. |
301 | - Added import() method for recursively importing existing Perl hash/ |
302 | array structures |
303 | - Fixed bug where optimize() wouldn't work if base level of DB was |
304 | an array instead of a hash. |
305 | |
306 | 0.91 Feb 12 02:30:22 2004 Pacific |
307 | - Fixed bug with splice() when length of removed section was 0 |
308 | - Updated POD re: circular refs and optimize() |
309 | - Had to jump version numbers to 0.91 because in previous releases |
310 | I used only a single digit after the decimal which was confusing |
311 | the CPAN indexer. |
312 | |
313 | 0.10 Feb 11 08:58:35 2004 Pacific |
314 | - Fixed bug where default file mode was CLEARING files (Thanks Rich!) |
315 | - Added experimental support for circular references |
316 | - Fixed bugs in shift(), unshift() and splice() where nested objects |
317 | in array would be recursively re-stored as basic hashes/arrays |
318 | - Fixed typos in POD docs |
319 | |
320 | 0.9 Feb 10 03:25:48 2004 Pacific |
321 | - Added Filters for storing/fetching keys/values |
322 | - Added hook for supplying own hashing algorithm |
323 | - FIxed some typos in POD docs, added new sections |
324 | |
325 | 0.8 Feb 8 02:38:22 2004 Pacific |
326 | - Renamed to DBM::Deep for CPAN |
327 | - Added optimize() method for rekindling unused space |
328 | - Now returning hybrid tie()/OO object from new() |
329 | - Basic error handling introduced |
330 | - Added debug mode for printing errors to STDERR |
331 | - Added TYPE_HASH and TYPE_ARRAY constants for "type" param |
332 | - Added clone() method for safe copying of objects |
333 | - Wrote POD documentation |
334 | - Added set_pack() function for manipulating LONG_SIZE / LONG_PACK |
335 | - Added aliases for most tied functions for public use |
336 | - Now setting binmode() on FileHandle for Win32 |
337 | - Added 45 unit tests |
338 | |
339 | 0.7 Jan 4 11:31:50 2003 UTC |
340 | - Renamed to DeepDB |
341 | - Changed file signature to DPDB (not compatible with older versions) |
342 | - Converted array length to packed long instead of sprintf()ed string |
343 | |
344 | 0.6 Dec 31 15:12:03 2002 UTC |
345 | - Some misc optimizations for speed |
346 | |
347 | 0.5 Oct 18 08:55:29 2002 UTC |
348 | - support for force_return_next parameter in traverse_index() method for |
349 | ultra-fast combined key search/removal |
350 | |
351 | 0.4 Oct 15 20:07:47 2002 UTC |
