1 | Revision history for DBM::Deep. |
2 | |
7c927437 |
3 | 1.0019_002 Jan XX XX:00:00 2010 EST |
4 | (This is the second developer release for 1.0020.) |
5 | (This version is compatible with 1.0014) |
6 | - Fixed bug where attempting to store a value tied to something other than |
7 | DBM::Deep would leave the file flocked. |
8 | - Added support for DBD::SQLite |
9 | - Build.PL has been extended to support sqlite vs. mysql |
10 | - Storage::DBI now detects between the two DBDs |
d451cf12 |
11 | - (RT #51888) Applied POD patch (Thanks, FWIE!) |
29460253 |
12 | - (RT #44981) Added VERSION to ::Array, ::Engine, and ::Hash |
1c62d370 |
13 | - Removed extraneous slashes from POD links (Thanks ilmari!) |
cd5303b4 |
14 | - (RT #50541) Fixed bug in clear() for hashes in the File backend. |
15 | - This has caused a regression in speed for clear() when clearing |
16 | large hashes using running with the File backend. ->clear() (on my |
17 | machine) now takes ( N / 40 ) ** (1.66) seconds. So, clearing 4000 |
18 | keys (as is the test in t/03_bighash.t) would take ~2070 seconds. |

20 | 1.0019_001 Dec 31 22:00:00 2009 EST |
21 | (This is the first developer release for 1.0020.) |
22 | (This version is compatible with 1.0014) |
23 | - DBM::Deep has been refactored to allow for multiple engines. There are two |
24 | engines built so far: |
25 | - File (the original engine) |
26 | - DBI (an engine based on DBI) |
27 | - The DBI engine has only been tested on MySQL and isn't transactional. |
28 | - InnoDB sucks horribly. When run in a sufficient isolation mode, it |
29 | creates deadlocks. |
30 | - A custom Build.PL has been written to allow for running tests under |
31 | CPAN.pm against the various engines. |
32 | - This also allows running the long tests under CPAN.pm |
33 | - This has meant a ton of refactoring. Hopefullly, this refactoring will |
34 | allow finding some of the niggly bugs more easily. Those tests have not |
35 | been enabled yet. That's the next developer release. |
36 | - Hopefully, this multi-engine support will allow deprecation of the file |
37 | format in the future. |

39 | 1.0014 Jun 13 23:15:00 2008 EST |
40 | - (This version is compatible with 1.0013) |
41 | - Fix for RT#36781 (t/44 has an unrequired dependency) |
5c0756fc |
42 | - lock() has been aliased to lock_exclusive(). There is now |
43 | a lock_shared() method. The :flock constants are no longer |
44 | imported into the DBM::Deep namespace. |
45 | **** THIS IS AN API CHANGE **** |

47 | 1.0013 Jun 13 23:15:00 2008 EST |
695c88b1 |
48 | - (This version is compatible with 1.0012) |
49 | - Fix for RT#30144 (Optimization failure on Win32) |
50 | - Fixed a bug in reindex_entry (Thanks, Wulfram Humann!) |
51 | |
08164b50 |
52 | 1.0012 Jun 09 15:00:00 2008 EST |
53 | - (This version is compatible with 1.0011) |
54 | - Fix for RT#30085 (Remove dependency on XS module) |
55 | - Thank you very much tachyon-II@Perlmonks!! |
9d3b38e4 |
56 | - This also resolves RT#35424 (DBM::Deep breaks XML::Twig). |
08164b50 |
57 | - Updated the POD with fixes that were made, but still on the TODO list. |
58 | - Bypass for RT#36419 (t/44_upgrade_db.t fails on *BSD) |
59 | - We're just going to skip that for now. It's a number-of-processes-open |
60 | issue. Best is to do a port to another module to do the heavy lifting. |
61 | |
62 | 1.0011 May 27 15:00:00 2008 EST |
63 | - (This version is compatible with 1.0010) |
64 | - A test has the wrong plan. |

66 | 1.0010 May 27 12:00:00 2008 EST |
b8370759 |
67 | - (This version is compatible with 1.0009) |
68 | - Fix for RT#35140 (invalid POD links) |
edd45134 |
69 | - Fix for RT#34819 (Cannot assign the same value back to the same location) |
70 | - Fix for RT#29957 (Cannot assign the same value back to the same location) |
71 | - Fix for RT#33863 (Cannot shift an arrayref from an array) |
72 | - When something is deleted from a DB, the value is export()ed, allowing it |
73 | to be saved. |
74 | - This exporting is only done if the refcount == 0 after the deletion. |

76 | 1.0009 Mar 19 12:00:00 2008 EDT |
77 | - (This version is compatible with 1.0008) |
78 | - Internal refactorings to prepare for some optimizations. |
79 | - _fh() has been removed. It was marked as private, so don't complain. |
80 | - Skip a test that was spuriously failing on Win32 (Thanks, Alias!) |
81 | |
45f047f8 |
82 | 1.0008 Mar 09 20:00:00 2008 EDT |
83 | - (This version is compatible with 1.0007) |
84 | - Fixed a number of Win32 issues (Reported by Steven Samelson - thank you!) |
85 | - Much thanks to Nigel Sandever and David Golden for their help |
86 | debugging the issues, particularly with DBM::Deep's usage of |
87 | File::Temp (which removes a number of warnings). |
88 | - Autovivification now works on Win32. It turns out that when a |
89 | process takes a shared flock on a file, it's not allowed to write to |
90 | it under Win32, unlike *nix. This is probably a good catch. |
91 | - Note: The fix is a hack. All locks are now exclusive until a |
92 | better fix is found. |
93 | |

94 | 1.0007 Jan 10 00:00:00 2008 EDT |
95 | - (This version is compatible with 1.0006) |
96 | - Applied a patch+failing test submitted by sprout@cpan.org. Thanks! |
97 | - Turns out that the case of 17 keys with the same first character in the |
98 | MD5 hash wasn't being tested for. This was a crashbug. |
99 | - A fix has been made to upgrade_db.pl (RT# 30067) |
100 | - The version determinations were in the wrong order or evaluation. This |
101 | meant that upgrade_db.pl wouldn't work as expected (or at all). |
102 | - Added a minimum Pod::Usage requirement (RT# 29976) |
103 | - It's an optional item in Build.PL |
104 | - utils/upgrade_db.pl now checks for that version, as does the test. |
105 | |

106 | 1.0006 Oct 01 23:15:00 2007 EDT |
107 | - (This version is compatible with 1.0005) |
108 | - Removed Clone and replaced it with a hand-written datastructure walker. |
109 | - This greatly reduces the footprint of a large import |
110 | - This bypasses a failure of Clone under Perl 5.9.5 |
111 | - Moved t/37_delete_edge_cases.t to t_attic because it wasn't really used |
112 | - import() has a stricter API now. This is a potentially incompatible API |
113 | change. Only HASH and ARRAY refs are now allowed and they must match the type |
114 | of the object being imported into. |
115 | |

116 | 1.0005 Oct 01 11:15:00 2007 EDT |
117 | - (This version is compatible with 1.0004) |
118 | - Added proper singleton support. This means that the following now works: |
119 | $db->{foo} = [ 1 .. 3]; |
120 | my $x = $db->{foo}; |
121 | my $y = $db->{foo}; |
122 | is( $x, $y ); # Now passes |
123 | - This means that Data::Dumper now properly reports when $db->{foo} = $db->{bar} |
124 | |
888453b9 |
125 | 1.0004 Sep 28 12:15:00 2007 EDT |
126 | - (This version is compatible with 1.0003) |
127 | - Fixed the Changes file (wrong version was displayed for 1.0003) |
128 | - Added filter sugar methods to be more API-compatible with other DBMs |
129 | - This was added to support a patch provided to IO::All so it can |
130 | use DBM::Deep as a DBM provider. |
131 | - Implemented _dump_file in order to display the file structure. As a |
132 | result, the following bugs were fixed: |
133 | - Arrays and hashes now clean up after themselves better. |
134 | - Bucketlists now clean up after themselves better. |
135 | - Reindexing properly clears the old bucketlist before freeing it. |
136 | |
137 | 1.0003 Sep 24 14:00:00 2007 EDT |
1cff45d7 |
138 | - THIS VERSION IS INCOMPATIBLE WITH FILES FROM ALL OTHER PRIOR VERSIONS. |
139 | - Further fixes for unshift/shift/splice and references (RT# 29583) |
140 | - To fix that, I had to put support for real references in. |
141 | - the 16 and 22 tests are now re-enabled. |
142 | - Yes, this means that real references work. See t/45_references.t |
143 | |
807f63a7 |
144 | 1.0002 Sep 20 22:00:00 2007 EDT |
145 | - (This version is compatible with 1.0001) |
146 | - Expanded _throw_error() so that it provides better information. |
147 | (Thanks brian d foy!) |
148 | - Fixed how shift, unshift, and splice work when there are references |
149 | being moved. It now no longer dies. |
150 | - Added diag in t/17_import.t to note that the failing tests on blead |
151 | are due to Clone being broken, not DBM::Deep. The tests will still |
152 | fail because I don't want users to install something that's broken |
153 | and deal with those bug reports. |
154 | |
151e0077 |
155 | 1.0001 Mar 12 16:15:00 2007 EDT |
156 | - (This version is compatible with 1.0000) |
157 | - Added a missing dependency on IO::Scalar (RT #25387) |
158 | - Fixed how t/44_upgrade_db.t and utils/upgrade_db.pl worked |
159 | - utils/upgrade_db.pl now uses #!perl, not #!/usr/bin/perl |
160 | - t/44_upgrade_db.t now explicitly calls $^X |
161 | (Thanks merlyn!) |
162 | |
163 | 1.0000 Feb 26 22:30:00 2007 EST |
e9b0b5f0 |
164 | - THIS VERSION IS INCOMPATIBLE WITH FILES FROM ALL OTHER PRIOR VERSIONS. |
165 | - To aid in this form of upgrades, DBM::Deep now checks the file format |
166 | version to make sure that it knows how to read it. |
167 | - db_upgrade.pl was added to utils/. This will -NOT- install onto |
168 | your system. This is deliberate. |
169 | - db_upgrade.pl will not handle developer release file formats. This |
170 | is due to the fact that all developer releases in preparation for a |
171 | given release share the same file version, even though the file |
172 | format may change. This is deliberate. |
173 | - Importing no longer takes place within a transaction |
174 | - The following parameters were added: |
175 | - data_sector_size - this determines the default size of a data sector. |
176 | - Correctly handle opening readonly files |
177 | |
151e0077 |
178 | 0.99_04 Jan 24 22:30:00 2007 EST |
2120a181 |
179 | - Added the missing lib/DBM/Deep.pod file to the MANIFEST |
180 | - Fixed a poorly-designed test that was failing depending on what Clone::Any |
e9b0b5f0 |
181 | was using. |
2120a181 |
182 | - All "use 5.6.0;" lines are now "use 5.006_000;" to avoid warnings about |
e9b0b5f0 |
183 | unsupported vstrings in 5.9.x |
2120a181 |
184 | |
151e0077 |
185 | 0.99_03 Jan 23 22:30:00 2007 EST |
2120a181 |
186 | - THIS VERSION IS INCOMPATIBLE WITH FILES FROM ALL OTHER PRIOR VERSIONS. |
187 | - The fileformat changed completely. I will be writing a converter, but |
188 | it's not there right now. Do NOT expect that this module will |
189 | correctly detect older versions and handle them sanely. Sanity will be |
190 | there for 1.00, but we're not there yet, are we? |
a8fdabda |
191 | - Converted to use FileHandle::Fmode to handle filehandle status checks |
13ff93d5 |
192 | - Fixed bug with deleting already-deleted items on Win32 (reported by Nigel Sandever) |
2120a181 |
193 | - The guts of how transactions work has been rewritten to better handle |
194 | some edgecases. This required a complete rewrite of the engine. |
195 | - Freespace management is now in place. It's not perfect, but it's there. |
196 | - The rewrite of the engine required a rewrite of how first_key/next_key |
197 | was implemented. This should result in significant speed improvements. |
198 | - Self-reference has been removed. This means you cannot do: |
199 | $db->{foo} = { x => 'y' }; |
200 | $db->{bar} = $db->{foo}; |
201 | I hope to be able to return this functionality by 1.00, but I cannot |
202 | promise anything. To do this properly, it requires refcounting in order |
203 | to correctly handle deletions and transactions. Once you move away from |
204 | a simple tree, everything becomes really hard. |
a8fdabda |
205 | |
c8602313 |
206 | 0.99_02 Apr 28 05:00:00 2006 Pacific |
207 | - Added missing file to the MANIFEST |
208 | |
209 | 0.99_01 Apr 27 18:00:00 2006 Pacific |
d2aefba0 |
210 | - Added explicit dependency on Perl 5.6.0 |
e06824f8 |
211 | - Digest::MD5 requires 5.6.0 |
212 | - Sub::Uplevel (dep of Test::Exception) requires 5.6.0 |
95967a5e |
213 | - Removed error()/clear_error() |
d2aefba0 |
214 | - All error-handling is done with die() |
e06824f8 |
215 | - Broke out DBM::Deep's code into DBM::Deep::Engine |
d2aefba0 |
216 | - Tied variables can no longer be assigned to a DBM::Deep object. |
217 | - This includes cross-file assignments. |
218 | - Autovivification now works |
219 | - This is a consequence of the fact that all assignments are tied. |
220 | - set_pack() and set_digest() have been removed. |
221 | - Instead, you will now pass the appropriate values into new() |
222 | - A pack_size parameter has been added to make 64-bit files easier |
c8602313 |
223 | - Transactions now work |
95967a5e |
224 | |
a8fdabda |
225 | 0.983 Apr 10 20:00:00 2006 Pacific |
226 | - Added patch inspired by Jeff Janes (Thanks!) |
227 | - Autovivification now works correctly |
228 | - The following now works correctly |
229 | my %hash = ( a => 1 ); |
230 | $db->{hash} = \%hash; |
231 | $hash{b} = 2; |
232 | cmp_ok( $db->{hash}{b}, '==', 2 ); |
233 | - (RT#18530) - DBM::Deep now plays nicely with -l |
234 | |
235 | 0.982 Mar 08 11:00:00 2006 Pacific |
236 | - Fixed smoketests that were failing on Win32 |
237 | - Added restriction for Perl 5.6.0 or higher. |
238 | - Digest::MD5 and Sub::Uplevel (dep of Test::Exception) require 5.6+ |
239 | |
240 | 0.981 Mar 06 11:00:00 2006 Pacific |
241 | - (RT#17947) - Fixed test that was failing on older Perls |
242 | |
9be51a89 |
243 | 0.98 Feb 28 11:00:00 2006 Pacific |
a8bd842e |
244 | - Added in patch by David Cantrell to allow use of DATA filehandle |
bcbe5355 |
245 | - Fixed bug where attempting to export() a structure that used autobless would die |
e3cb84dc |
246 | - Fixed arraytest slowness by localizing $SIG{__DIE__} to prevent Test::Builder's |
247 | $SIG{__DIE__} from being called. (q.v. http://perldoc.perl.org/functions/eval.html) |
4d35d856 |
248 | - More methods have been made private: |
249 | - root() is now _root() |
250 | - base_offset() is now _base_offset() |
251 | - fh() is now _fh() |
252 | - type() is now _type() |
253 | - precalc_sizes() is now _precalc_sizes() |
e3cb84dc |
254 | |
6d049f2c |
255 | 0.97 Feb 24 10:00:00 2006 Pacific |
e096f245 |
256 | - Reorganization of distribution to a more standard layout |
ffed8b01 |
257 | - Migration to Module::Build with EU::MM backwards compatibility |
e096f245 |
258 | - Migration of all tests to use Test::More and Test::Exception |
259 | - Added Devel::Cover report to DBM::Deep POD |
260 | - Test coverage improved to 89.6% (and climbing) |
8b957036 |
261 | - The following methods have been renamed to reflect their private nature: |
262 | - init() is now _init() |
14a3acb6 |
263 | - open() is now _open() |
0207d648 |
264 | - close() is now _close() |
261d1296 |
265 | - load_tag() is now _load_tag() |
266 | - index_lookup() is now _index_lookup() |
267 | - add_bucket() is now _add_bucket() |
268 | - get_bucket_value() is now _get_bucket_value() |
269 | - delete_bucket() is now _delete_bucket() |
270 | - bucket_exists() is now _bucket_exists() |
271 | - find_bucket_list() is now _find_bucket_list() |
272 | - traverse_index() is now _traverse_index() |
273 | - get_next_key() is now _get_next_key() |
274 | - copy_node() is now _copy_node() |
275 | - throw_error() is now _throw_error() |
217fef02 |
276 | - The various tied classes have been broken out. This means that testing |
277 | "ref( $obj ) eq 'DBM::Deep'" will now fail. The correct test is |
278 | "eval { $obj->isa( 'DBM::Deep' ) }". |
279 | - The various methods like push and delete now have the same return values as |
280 | the standard builtins. |
9d085683 |
281 | - TIEARRAY and TIEHASH now check their parameters more thoroughly |
e096f245 |
282 | - Negative indices for arrays works as expected, including throwing the appropriate |
283 | errors. |
26138c00 |
284 | - RT #16877 is fixed (DBM::Deep broken with Perl 5.9.3+). |
285 | - RT #14893 is fixed (tie() and new() use different parameter lists). |
286 | - A bug with optimize and threading is fixed. |
287 | - autobless has received some attention, resulting in a number of bugs fixed. |
90f93b43 |
288 | - Removed mode option as it just caused confusion. |
3ea61317 |
289 | - Removed volatile option as it is pretty useless (use locking instead) |
290 | - Locking now implicitly enables autoflush |
ffed8b01 |
291 | |
292 | 0.96 Oct 14 09:55:00 2005 Pacific |
293 | - Fixed build (OS X hidden files killed it) |
294 | - You can now pass in an optional filehandle to the constructor |
295 | |
296 | 0.95 Oct 12 13:58:00 2005 Pacific |
297 | - Added optional autobless flag to preserve and restore blessed hashes |
298 | - Fixed bug where 0 could not be fetched using get_next_key |
299 | - Fixed bug where tie() constructor didn't accept a hash ref for args |
300 | - optimize() now preserves user/group/permissions |
301 | - Errors are now FATAL (meaning it calls die()), unless you set debug flag |
302 | |
303 | 0.94 Apr 13 19:00:26 2004 Pacific |
304 | - Fixed bug reported by John Cardenas (corruption at key level when |
305 | replace of less data was done on bucket) |
306 | |
307 | 0.93 Feb 15 19:53:17 2004 Pacific |
308 | - Fixed optmize() on Win32 where orig file couldn't be overwritten unless |
309 | filehandle was closed first. This change introduces a potential race |
310 | condition when using locking and optmize() on Win32, but it can be |
311 | fixed in the future using a soft copy instead of Perl's rename(). |
312 | |
313 | 0.92 Feb 12 19:10:22 2004 Pacific |
314 | - Fixed bug where passing a reference to a different DBM::Deep object |
315 | would still result in an internal reference. |
316 | - Added export() method for recursively extracting hashes/arrays into |
317 | standard in-memory Perl structures. |
318 | - Added import() method for recursively importing existing Perl hash/ |
319 | array structures |
320 | - Fixed bug where optimize() wouldn't work if base level of DB was |
321 | an array instead of a hash. |
322 | |
323 | 0.91 Feb 12 02:30:22 2004 Pacific |
324 | - Fixed bug with splice() when length of removed section was 0 |
325 | - Updated POD re: circular refs and optimize() |
326 | - Had to jump version numbers to 0.91 because in previous releases |
327 | I used only a single digit after the decimal which was confusing |
328 | the CPAN indexer. |
329 | |
330 | 0.10 Feb 11 08:58:35 2004 Pacific |
331 | - Fixed bug where default file mode was CLEARING files (Thanks Rich!) |
332 | - Added experimental support for circular references |
333 | - Fixed bugs in shift(), unshift() and splice() where nested objects |
334 | in array would be recursively re-stored as basic hashes/arrays |
335 | - Fixed typos in POD docs |
336 | |
337 | 0.9 Feb 10 03:25:48 2004 Pacific |
338 | - Added Filters for storing/fetching keys/values |
339 | - Added hook for supplying own hashing algorithm |
340 | - FIxed some typos in POD docs, added new sections |
341 | |
342 | 0.8 Feb 8 02:38:22 2004 Pacific |
343 | - Renamed to DBM::Deep for CPAN |
