1 Revision history for DBM::Deep (ordered by revision number).
3 1.0019_003 Feb 16 22:00:00 2010 EST
4 (This is the third developer release for 1.0020.)
5 (This version is compatible with 1.0016)
6 - Fixed problem where "./Build test" wouldn't actually -do- anything.
7 - (No-one apparently tried to install this till Steven Lembark. Thanks!)
8 - Fixed speed regression with keys in the File backend.
9 - Introduced in 1.0019_002 to fix #50541
11 - (RT #53575) Recursion failure in STORE (Thanks, SPROUT)
12 - Merged the rest of the fixes from 1.0015 and 1.0016
13 - Thanks to our new co-maintainer, SPROUT! :)
14 - Had to turn off singleton support in the File backend because the caching
15 was causing havoc with transactions. Turning on fatal warnings does give
16 apparently important information.
17 - Oh - forgot to mention that fatal warnings are now on in all files.
19 1.0019_002 Jan 05 22:30:00 2010 EST
20 (This is the second developer release for 1.0020.)
21 (This version is compatible with 1.0014)
22 - Fixed bug where attempting to store a value tied to something other than
23 DBM::Deep would leave the file flocked.
24 - Added support for DBD::SQLite
25 - Build.PL has been extended to support sqlite vs. mysql
26 - Storage::DBI now detects between the two DBDs
27 - (RT #51888) Applied POD patch (Thanks, FWIE!)
28 - (RT #44981) Added VERSION to ::Array, ::Engine, and ::Hash
29 - Removed extraneous slashes from POD links (Thanks ilmari!)
30 - (RT #50541) Fixed bug in clear() for hashes in the File backend.
31 - This has caused a regression in speed for clear() when clearing
32 large hashes using running with the File backend. ->clear() (on my
33 machine) now takes ( N / 40 ) ** (1.66) seconds. So, clearing 4000
34 keys (as is the test in t/03_bighash.t) would take ~2070 seconds.
35 - (RT #40782) Fixed bug when handling a key of '0' (Thanks Sterling!)
36 - (RT #48031) Fixed bug with localized $, (Thanks, SPROUT!)
38 1.0019_001 Dec 31 22:00:00 2009 EST
39 (This is the first developer release for 1.0020.)
40 (This version is compatible with 1.0014)
41 - DBM::Deep has been refactored to allow for multiple engines. There are two
43 - File (the original engine)
44 - DBI (an engine based on DBI)
45 - The DBI engine has only been tested on MySQL and isn't transactional.
46 - InnoDB sucks horribly. When run in a sufficient isolation mode, it
48 - A custom Build.PL has been written to allow for running tests under
49 CPAN.pm against the various engines.
50 - This also allows running the long tests under CPAN.pm
51 - This has meant a ton of refactoring. Hopefullly, this refactoring will
52 allow finding some of the niggly bugs more easily. Those tests have not
53 been enabled yet. That's the next developer release.
54 - Hopefully, this multi-engine support will allow deprecation of the file
57 1.0016 Feb 05 22:10:00 2010 PST
58 - (This version is compatible with 1.0015)
59 - New caveat in the docs explaining stale references (RT#42129)
60 - All included modules now have the same version in META.yml, so
61 the CPAN shell will no longer try to downgrade.
62 - Fixed bug in clear() for hashes (RT#50541)
64 1.0015 Jan 25 22:05:00 2010 PST
65 - (This version is compatible with 1.0014)
66 - Fix deep recursion errors (RT#53575)
67 - Avoid leaving temp files lying around (RT#32462)
68 - (RT #48031) Fixed bug with localized $, (Thanks, SPROUT!)
70 1.0014 Jun 13 23:15:00 2008 EST
71 - (This version is compatible with 1.0013)
72 - Fix for RT#36781 (t/44 has an unrequired dependency)
73 - lock() has been aliased to lock_exclusive(). There is now
74 a lock_shared() method. The :flock constants are no longer
75 imported into the DBM::Deep namespace.
76 **** THIS IS AN API CHANGE ****
78 1.0013 Jun 13 23:15:00 2008 EST
79 - (This version is compatible with 1.0012)
80 - Fix for RT#30144 (Optimization failure on Win32)
81 - Fixed a bug in reindex_entry (Thanks, Wulfram Humann!)
83 1.0012 Jun 09 15:00:00 2008 EST
84 - (This version is compatible with 1.0011)
85 - Fix for RT#30085 (Remove dependency on XS module)
86 - Thank you very much tachyon-II@Perlmonks!!
87 - This also resolves RT#35424 (DBM::Deep breaks XML::Twig).
88 - Updated the POD with fixes that were made, but still on the TODO list.
89 - Bypass for RT#36419 (t/44_upgrade_db.t fails on *BSD)
90 - We're just going to skip that for now. It's a number-of-processes-open
91 issue. Best is to do a port to another module to do the heavy lifting.
93 1.0011 May 27 15:00:00 2008 EST
94 - (This version is compatible with 1.0010)
95 - A test has the wrong plan.
97 1.0010 May 27 12:00:00 2008 EST
98 - (This version is compatible with 1.0009)
99 - Fix for RT#35140 (invalid POD links)
100 - Fix for RT#34819 (Cannot assign the same value back to the same location)
101 - Fix for RT#29957 (Cannot assign the same value back to the same location)
102 - Fix for RT#33863 (Cannot shift an arrayref from an array)
103 - When something is deleted from a DB, the value is export()ed, allowing it
105 - This exporting is only done if the refcount == 0 after the deletion.
107 1.0009 Mar 19 12:00:00 2008 EDT
108 - (This version is compatible with 1.0008)
109 - Internal refactorings to prepare for some optimizations.
110 - _fh() has been removed. It was marked as private, so don't complain.
111 - Skip a test that was spuriously failing on Win32 (Thanks, Alias!)
113 1.0008 Mar 09 20:00:00 2008 EDT
114 - (This version is compatible with 1.0007)
115 - Fixed a number of Win32 issues (Reported by Steven Samelson - thank you!)
116 - Much thanks to Nigel Sandever and David Golden for their help
117 debugging the issues, particularly with DBM::Deep's usage of
118 File::Temp (which removes a number of warnings).
119 - Autovivification now works on Win32. It turns out that when a
120 process takes a shared flock on a file, it's not allowed to write to
121 it under Win32, unlike *nix. This is probably a good catch.
122 - Note: The fix is a hack. All locks are now exclusive until a
125 1.0007 Jan 10 00:00:00 2008 EDT
126 - (This version is compatible with 1.0006)
127 - Applied a patch+failing test submitted by sprout@cpan.org. Thanks!
128 - Turns out that the case of 17 keys with the same first character in the
129 MD5 hash wasn't being tested for. This was a crashbug.
130 - A fix has been made to upgrade_db.pl (RT# 30067)
131 - The version determinations were in the wrong order or evaluation. This
132 meant that upgrade_db.pl wouldn't work as expected (or at all).
133 - Added a minimum Pod::Usage requirement (RT# 29976)
134 - It's an optional item in Build.PL
135 - utils/upgrade_db.pl now checks for that version, as does the test.
137 1.0006 Oct 01 23:15:00 2007 EDT
138 - (This version is compatible with 1.0005)
139 - Removed Clone and replaced it with a hand-written datastructure walker.
140 - This greatly reduces the footprint of a large import
141 - This bypasses a failure of Clone under Perl 5.9.5
142 - Moved t/37_delete_edge_cases.t to t_attic because it wasn't really used
143 - import() has a stricter API now. This is a potentially incompatible API
144 change. Only HASH and ARRAY refs are now allowed and they must match the type
145 of the object being imported into.
147 1.0005 Oct 01 11:15:00 2007 EDT
148 - (This version is compatible with 1.0004)
149 - Added proper singleton support. This means that the following now works:
150 $db->{foo} = [ 1 .. 3];
153 is( $x, $y ); # Now passes
154 - This means that Data::Dumper now properly reports when $db->{foo} = $db->{bar}
156 1.0004 Sep 28 12:15:00 2007 EDT
157 - (This version is compatible with 1.0003)
158 - Fixed the Changes file (wrong version was displayed for 1.0003)
159 - Added filter sugar methods to be more API-compatible with other DBMs
160 - This was added to support a patch provided to IO::All so it can
161 use DBM::Deep as a DBM provider.
162 - Implemented _dump_file in order to display the file structure. As a
163 result, the following bugs were fixed:
164 - Arrays and hashes now clean up after themselves better.
165 - Bucketlists now clean up after themselves better.
166 - Reindexing properly clears the old bucketlist before freeing it.
168 1.0003 Sep 24 14:00:00 2007 EDT
169 - THIS VERSION IS INCOMPATIBLE WITH FILES FROM ALL OTHER PRIOR VERSIONS.
170 - Further fixes for unshift/shift/splice and references (RT# 29583)
171 - To fix that, I had to put support for real references in.
172 - the 16 and 22 tests are now re-enabled.
173 - Yes, this means that real references work. See t/45_references.t
175 1.0002 Sep 20 22:00:00 2007 EDT
176 - (This version is compatible with 1.0001)
177 - Expanded _throw_error() so that it provides better information.
178 (Thanks brian d foy!)
179 - Fixed how shift, unshift, and splice work when there are references
180 being moved. It now no longer dies.
181 - Added diag in t/17_import.t to note that the failing tests on blead
182 are due to Clone being broken, not DBM::Deep. The tests will still
183 fail because I don't want users to install something that's broken
184 and deal with those bug reports.
186 1.0001 Mar 12 16:15:00 2007 EDT
187 - (This version is compatible with 1.0000)
188 - Added a missing dependency on IO::Scalar (RT #25387)
189 - Fixed how t/44_upgrade_db.t and utils/upgrade_db.pl worked
190 - utils/upgrade_db.pl now uses #!perl, not #!/usr/bin/perl
191 - t/44_upgrade_db.t now explicitly calls $^X
194 1.0000 Feb 26 22:30:00 2007 EST
195 - THIS VERSION IS INCOMPATIBLE WITH FILES FROM ALL OTHER PRIOR VERSIONS.
196 - To aid in this form of upgrades, DBM::Deep now checks the file format
197 version to make sure that it knows how to read it.
198 - db_upgrade.pl was added to utils/. This will -NOT- install onto
199 your system. This is deliberate.
200 - db_upgrade.pl will not handle developer release file formats. This
201 is due to the fact that all developer releases in preparation for a
202 given release share the same file version, even though the file
203 format may change. This is deliberate.
204 - Importing no longer takes place within a transaction
205 - The following parameters were added:
206 - data_sector_size - this determines the default size of a data sector.
207 - Correctly handle opening readonly files
209 0.99_04 Jan 24 22:30:00 2007 EST
210 - Added the missing lib/DBM/Deep.pod file to the MANIFEST
211 - Fixed a poorly-designed test that was failing depending on what Clone::Any
213 - All "use 5.6.0;" lines are now "use 5.006_000;" to avoid warnings about
214 unsupported vstrings in 5.9.x
216 0.99_03 Jan 23 22:30:00 2007 EST
217 - THIS VERSION IS INCOMPATIBLE WITH FILES FROM ALL OTHER PRIOR VERSIONS.
218 - The fileformat changed completely. I will be writing a converter, but
219 it's not there right now. Do NOT expect that this module will
220 correctly detect older versions and handle them sanely. Sanity will be
221 there for 1.00, but we're not there yet, are we?
222 - Converted to use FileHandle::Fmode to handle filehandle status checks
223 - Fixed bug with deleting already-deleted items on Win32 (reported by Nigel Sandever)
224 - The guts of how transactions work has been rewritten to better handle
225 some edgecases. This required a complete rewrite of the engine.
226 - Freespace management is now in place. It's not perfect, but it's there.
227 - The rewrite of the engine required a rewrite of how first_key/next_key
228 was implemented. This should result in significant speed improvements.
229 - Self-reference has been removed. This means you cannot do:
230 $db->{foo} = { x => 'y' };
231 $db->{bar} = $db->{foo};
232 I hope to be able to return this functionality by 1.00, but I cannot
233 promise anything. To do this properly, it requires refcounting in order
234 to correctly handle deletions and transactions. Once you move away from
235 a simple tree, everything becomes really hard.
237 0.99_02 Apr 28 05:00:00 2006 Pacific
238 - Added missing file to the MANIFEST
240 0.99_01 Apr 27 18:00:00 2006 Pacific
241 - Added explicit dependency on Perl 5.6.0
242 - Digest::MD5 requires 5.6.0
243 - Sub::Uplevel (dep of Test::Exception) requires 5.6.0
244 - Removed error()/clear_error()
245 - All error-handling is done with die()
246 - Broke out DBM::Deep's code into DBM::Deep::Engine
247 - Tied variables can no longer be assigned to a DBM::Deep object.
248 - This includes cross-file assignments.
249 - Autovivification now works
250 - This is a consequence of the fact that all assignments are tied.
251 - set_pack() and set_digest() have been removed.
252 - Instead, you will now pass the appropriate values into new()
253 - A pack_size parameter has been added to make 64-bit files easier
254 - Transactions now work
256 0.983 Apr 10 20:00:00 2006 Pacific
257 - Added patch inspired by Jeff Janes (Thanks!)
258 - Autovivification now works correctly
259 - The following now works correctly
260 my %hash = ( a => 1 );
261 $db->{hash} = \%hash;
263 cmp_ok( $db->{hash}{b}, '==', 2 );
264 - (RT#18530) - DBM::Deep now plays nicely with -l
266 0.982 Mar 08 11:00:00 2006 Pacific
267 - Fixed smoketests that were failing on Win32
268 - Added restriction for Perl 5.6.0 or higher.
269 - Digest::MD5 and Sub::Uplevel (dep of Test::Exception) require 5.6+
271 0.981 Mar 06 11:00:00 2006 Pacific
272 - (RT#17947) - Fixed test that was failing on older Perls
274 0.98 Feb 28 11:00:00 2006 Pacific
275 - Added in patch by David Cantrell to allow use of DATA filehandle
276 - Fixed bug where attempting to export() a structure that used autobless would die
277 - Fixed arraytest slowness by localizing $SIG{__DIE__} to prevent Test::Builder's
278 $SIG{__DIE__} from being called. (q.v. http://perldoc.perl.org/functions/eval.html)
279 - More methods have been made private:
280 - root() is now _root()
281 - base_offset() is now _base_offset()
283 - type() is now _type()
284 - precalc_sizes() is now _precalc_sizes()
286 0.97 Feb 24 10:00:00 2006 Pacific
287 - Reorganization of distribution to a more standard layout
288 - Migration to Module::Build with EU::MM backwards compatibility
289 - Migration of all tests to use Test::More and Test::Exception
290 - Added Devel::Cover report to DBM::Deep POD
291 - Test coverage improved to 89.6% (and climbing)
292 - The following methods have been renamed to reflect their private nature:
293 - init() is now _init()
294 - open() is now _open()
295 - close() is now _close()
296 - load_tag() is now _load_tag()
297 - index_lookup() is now _index_lookup()
298 - add_bucket() is now _add_bucket()
299 - get_bucket_value() is now _get_bucket_value()
300 - delete_bucket() is now _delete_bucket()
301 - bucket_exists() is now _bucket_exists()
302 - find_bucket_list() is now _find_bucket_list()
303 - traverse_index() is now _traverse_index()
304 - get_next_key() is now _get_next_key()
305 - copy_node() is now _copy_node()
306 - throw_error() is now _throw_error()
307 - The various tied classes have been broken out. This means that testing
308 "ref( $obj ) eq 'DBM::Deep'" will now fail. The correct test is
309 "eval { $obj->isa( 'DBM::Deep' ) }".
310 - The various methods like push and delete now have the same return values as
311 the standard builtins.
312 - TIEARRAY and TIEHASH now check their parameters more thoroughly
313 - Negative indices for arrays works as expected, including throwing the appropriate
315 - RT #16877 is fixed (DBM::Deep broken with Perl 5.9.3+).
316 - RT #14893 is fixed (tie() and new() use different parameter lists).
317 - A bug with optimize and threading is fixed.
318 - autobless has received some attention, resulting in a number of bugs fixed.
319 - Removed mode option as it just caused confusion.
320 - Removed volatile option as it is pretty useless (use locking instead)
321 - Locking now implicitly enables autoflush
323 0.96 Oct 14 09:55:00 2005 Pacific
324 - Fixed build (OS X hidden files killed it)
325 - You can now pass in an optional filehandle to the constructor
327 0.95 Oct 12 13:58:00 2005 Pacific
328 - Added optional autobless flag to preserve and restore blessed hashes
329 - Fixed bug where 0 could not be fetched using get_next_key
330 - Fixed bug where tie() constructor didn't accept a hash ref for args
331 - optimize() now preserves user/group/permissions
332 - Errors are now FATAL (meaning it calls die()), unless you set debug flag
334 0.94 Apr 13 19:00:26 2004 Pacific
335 - Fixed bug reported by John Cardenas (corruption at key level when
336 replace of less data was done on bucket)
338 0.93 Feb 15 19:53:17 2004 Pacific
339 - Fixed optmize() on Win32 where orig file couldn't be overwritten unless
340 filehandle was closed first. This change introduces a potential race
341 condition when using locking and optmize() on Win32, but it can be
342 fixed in the future using a soft copy instead of Perl's rename().
344 0.92 Feb 12 19:10:22 2004 Pacific
345 - Fixed bug where passing a reference to a different DBM::Deep object
346 would still result in an internal reference.
347 - Added export() method for recursively extracting hashes/arrays into
348 standard in-memory Perl structures.
349 - Added import() method for recursively importing existing Perl hash/
351 - Fixed bug where optimize() wouldn't work if base level of DB was
352 an array instead of a hash.
354 0.91 Feb 12 02:30:22 2004 Pacific
355 - Fixed bug with splice() when length of removed section was 0
356 - Updated POD re: circular refs and optimize()
357 - Had to jump version numbers to 0.91 because in previous releases
358 I used only a single digit after the decimal which was confusing
361 0.10 Feb 11 08:58:35 2004 Pacific
362 - Fixed bug where default file mode was CLEARING files (Thanks Rich!)
363 - Added experimental support for circular references
364 - Fixed bugs in shift(), unshift() and splice() where nested objects
365 in array would be recursively re-stored as basic hashes/arrays
366 - Fixed typos in POD docs
368 0.9 Feb 10 03:25:48 2004 Pacific
369 - Added Filters for storing/fetching keys/values
370 - Added hook for supplying own hashing algorithm
371 - FIxed some typos in POD docs, added new sections
373 0.8 Feb 8 02:38:22 2004 Pacific
374 - Renamed to DBM::Deep for CPAN
375 - Added optimize() method for rekindling unused space
376 - Now returning hybrid tie()/OO object from new()
377 - Basic error handling introduced
378 - Added debug mode for printing errors to STDERR
379 - Added TYPE_HASH and TYPE_ARRAY constants for "type" param
380 - Added clone() method for safe copying of objects
381 - Wrote POD documentation
382 - Added set_pack() function for manipulating LONG_SIZE / LONG_PACK
383 - Added aliases for most tied functions for public use
384 - Now setting binmode() on FileHandle for Win32
385 - Added 45 unit tests
387 0.7 Jan 4 11:31:50 2003 UTC
389 - Changed file signature to DPDB (not compatible with older versions)
390 - Converted array length to packed long instead of sprintf()ed string
392 0.6 Dec 31 15:12:03 2002 UTC
393 - Some misc optimizations for speed
395 0.5 Oct 18 08:55:29 2002 UTC
396 - support for force_return_next parameter in traverse_index() method for
397 ultra-fast combined key search/removal
399 0.4 Oct 15 20:07:47 2002 UTC
400 - now making sure filehandle is open for all DB calls
402 0.3 Oct 3 19:04:13 2002 UTC
403 - fixed bug that could cause corrupted data when using locking
405 0.2 Aug 6 16:37:32 2002 UTC
406 - Removed base index caching, as it can cause problems when two processes
407 are populating the db at the same time (even with locking)
409 0.1 Jun 3 08:06:26 2002 UTC
