1 Revision history for DBM::Deep.
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
11 - (RT #51888) Applied POD patch (Thanks, FWIE!)
12 - (RT #44981) Added VERSION to ::Array, ::Engine, and ::Hash
13 - Removed extraneous slashes from POD links (Thanks ilmari!)
15 1.0019_001 Dec 31 22:00:00 2009 EST
16 (This is the first developer release for 1.0020.)
17 (This version is compatible with 1.0014)
18 - DBM::Deep has been refactored to allow for multiple engines. There are two
20 - File (the original engine)
21 - DBI (an engine based on DBI)
22 - The DBI engine has only been tested on MySQL and isn't transactional.
23 - InnoDB sucks horribly. When run in a sufficient isolation mode, it
25 - A custom Build.PL has been written to allow for running tests under
26 CPAN.pm against the various engines.
27 - This also allows running the long tests under CPAN.pm
28 - This has meant a ton of refactoring. Hopefullly, this refactoring will
29 allow finding some of the niggly bugs more easily. Those tests have not
30 been enabled yet. That's the next developer release.
31 - Hopefully, this multi-engine support will allow deprecation of the file
34 1.0014 Jun 13 23:15:00 2008 EST
35 - (This version is compatible with 1.0013)
36 - Fix for RT#36781 (t/44 has an unrequired dependency)
37 - lock() has been aliased to lock_exclusive(). There is now
38 a lock_shared() method. The :flock constants are no longer
39 imported into the DBM::Deep namespace.
40 **** THIS IS AN API CHANGE ****
42 1.0013 Jun 13 23:15:00 2008 EST
43 - (This version is compatible with 1.0012)
44 - Fix for RT#30144 (Optimization failure on Win32)
45 - Fixed a bug in reindex_entry (Thanks, Wulfram Humann!)
47 1.0012 Jun 09 15:00:00 2008 EST
48 - (This version is compatible with 1.0011)
49 - Fix for RT#30085 (Remove dependency on XS module)
50 - Thank you very much tachyon-II@Perlmonks!!
51 - This also resolves RT#35424 (DBM::Deep breaks XML::Twig).
52 - Updated the POD with fixes that were made, but still on the TODO list.
53 - Bypass for RT#36419 (t/44_upgrade_db.t fails on *BSD)
54 - We're just going to skip that for now. It's a number-of-processes-open
55 issue. Best is to do a port to another module to do the heavy lifting.
57 1.0011 May 27 15:00:00 2008 EST
58 - (This version is compatible with 1.0010)
59 - A test has the wrong plan.
61 1.0010 May 27 12:00:00 2008 EST
62 - (This version is compatible with 1.0009)
63 - Fix for RT#35140 (invalid POD links)
64 - Fix for RT#34819 (Cannot assign the same value back to the same location)
65 - Fix for RT#29957 (Cannot assign the same value back to the same location)
66 - Fix for RT#33863 (Cannot shift an arrayref from an array)
67 - When something is deleted from a DB, the value is export()ed, allowing it
69 - This exporting is only done if the refcount == 0 after the deletion.
71 1.0009 Mar 19 12:00:00 2008 EDT
72 - (This version is compatible with 1.0008)
73 - Internal refactorings to prepare for some optimizations.
74 - _fh() has been removed. It was marked as private, so don't complain.
75 - Skip a test that was spuriously failing on Win32 (Thanks, Alias!)
77 1.0008 Mar 09 20:00:00 2008 EDT
78 - (This version is compatible with 1.0007)
79 - Fixed a number of Win32 issues (Reported by Steven Samelson - thank you!)
80 - Much thanks to Nigel Sandever and David Golden for their help
81 debugging the issues, particularly with DBM::Deep's usage of
82 File::Temp (which removes a number of warnings).
83 - Autovivification now works on Win32. It turns out that when a
84 process takes a shared flock on a file, it's not allowed to write to
85 it under Win32, unlike *nix. This is probably a good catch.
86 - Note: The fix is a hack. All locks are now exclusive until a
89 1.0007 Jan 10 00:00:00 2008 EDT
90 - (This version is compatible with 1.0006)
91 - Applied a patch+failing test submitted by sprout@cpan.org. Thanks!
92 - Turns out that the case of 17 keys with the same first character in the
93 MD5 hash wasn't being tested for. This was a crashbug.
94 - A fix has been made to upgrade_db.pl (RT# 30067)
95 - The version determinations were in the wrong order or evaluation. This
96 meant that upgrade_db.pl wouldn't work as expected (or at all).
97 - Added a minimum Pod::Usage requirement (RT# 29976)
98 - It's an optional item in Build.PL
99 - utils/upgrade_db.pl now checks for that version, as does the test.
101 1.0006 Oct 01 23:15:00 2007 EDT
102 - (This version is compatible with 1.0005)
103 - Removed Clone and replaced it with a hand-written datastructure walker.
104 - This greatly reduces the footprint of a large import
105 - This bypasses a failure of Clone under Perl 5.9.5
106 - Moved t/37_delete_edge_cases.t to t_attic because it wasn't really used
107 - import() has a stricter API now. This is a potentially incompatible API
108 change. Only HASH and ARRAY refs are now allowed and they must match the type
109 of the object being imported into.
111 1.0005 Oct 01 11:15:00 2007 EDT
112 - (This version is compatible with 1.0004)
113 - Added proper singleton support. This means that the following now works:
114 $db->{foo} = [ 1 .. 3];
117 is( $x, $y ); # Now passes
118 - This means that Data::Dumper now properly reports when $db->{foo} = $db->{bar}
120 1.0004 Sep 28 12:15:00 2007 EDT
121 - (This version is compatible with 1.0003)
122 - Fixed the Changes file (wrong version was displayed for 1.0003)
123 - Added filter sugar methods to be more API-compatible with other DBMs
124 - This was added to support a patch provided to IO::All so it can
125 use DBM::Deep as a DBM provider.
126 - Implemented _dump_file in order to display the file structure. As a
127 result, the following bugs were fixed:
128 - Arrays and hashes now clean up after themselves better.
129 - Bucketlists now clean up after themselves better.
130 - Reindexing properly clears the old bucketlist before freeing it.
132 1.0003 Sep 24 14:00:00 2007 EDT
133 - THIS VERSION IS INCOMPATIBLE WITH FILES FROM ALL OTHER PRIOR VERSIONS.
134 - Further fixes for unshift/shift/splice and references (RT# 29583)
135 - To fix that, I had to put support for real references in.
136 - the 16 and 22 tests are now re-enabled.
137 - Yes, this means that real references work. See t/45_references.t
139 1.0002 Sep 20 22:00:00 2007 EDT
140 - (This version is compatible with 1.0001)
141 - Expanded _throw_error() so that it provides better information.
142 (Thanks brian d foy!)
143 - Fixed how shift, unshift, and splice work when there are references
144 being moved. It now no longer dies.
145 - Added diag in t/17_import.t to note that the failing tests on blead
146 are due to Clone being broken, not DBM::Deep. The tests will still
147 fail because I don't want users to install something that's broken
148 and deal with those bug reports.
150 1.0001 Mar 12 16:15:00 2007 EDT
151 - (This version is compatible with 1.0000)
152 - Added a missing dependency on IO::Scalar (RT #25387)
153 - Fixed how t/44_upgrade_db.t and utils/upgrade_db.pl worked
154 - utils/upgrade_db.pl now uses #!perl, not #!/usr/bin/perl
155 - t/44_upgrade_db.t now explicitly calls $^X
158 1.0000 Feb 26 22:30:00 2007 EST
159 - THIS VERSION IS INCOMPATIBLE WITH FILES FROM ALL OTHER PRIOR VERSIONS.
160 - To aid in this form of upgrades, DBM::Deep now checks the file format
161 version to make sure that it knows how to read it.
162 - db_upgrade.pl was added to utils/. This will -NOT- install onto
163 your system. This is deliberate.
164 - db_upgrade.pl will not handle developer release file formats. This
165 is due to the fact that all developer releases in preparation for a
166 given release share the same file version, even though the file
167 format may change. This is deliberate.
168 - Importing no longer takes place within a transaction
169 - The following parameters were added:
170 - data_sector_size - this determines the default size of a data sector.
171 - Correctly handle opening readonly files
173 0.99_04 Jan 24 22:30:00 2007 EST
174 - Added the missing lib/DBM/Deep.pod file to the MANIFEST
175 - Fixed a poorly-designed test that was failing depending on what Clone::Any
177 - All "use 5.6.0;" lines are now "use 5.006_000;" to avoid warnings about
178 unsupported vstrings in 5.9.x
180 0.99_03 Jan 23 22:30:00 2007 EST
181 - THIS VERSION IS INCOMPATIBLE WITH FILES FROM ALL OTHER PRIOR VERSIONS.
182 - The fileformat changed completely. I will be writing a converter, but
183 it's not there right now. Do NOT expect that this module will
184 correctly detect older versions and handle them sanely. Sanity will be
185 there for 1.00, but we're not there yet, are we?
186 - Converted to use FileHandle::Fmode to handle filehandle status checks
187 - Fixed bug with deleting already-deleted items on Win32 (reported by Nigel Sandever)
188 - The guts of how transactions work has been rewritten to better handle
189 some edgecases. This required a complete rewrite of the engine.
190 - Freespace management is now in place. It's not perfect, but it's there.
191 - The rewrite of the engine required a rewrite of how first_key/next_key
192 was implemented. This should result in significant speed improvements.
193 - Self-reference has been removed. This means you cannot do:
194 $db->{foo} = { x => 'y' };
195 $db->{bar} = $db->{foo};
196 I hope to be able to return this functionality by 1.00, but I cannot
197 promise anything. To do this properly, it requires refcounting in order
198 to correctly handle deletions and transactions. Once you move away from
199 a simple tree, everything becomes really hard.
201 0.99_02 Apr 28 05:00:00 2006 Pacific
202 - Added missing file to the MANIFEST
204 0.99_01 Apr 27 18:00:00 2006 Pacific
205 - Added explicit dependency on Perl 5.6.0
206 - Digest::MD5 requires 5.6.0
207 - Sub::Uplevel (dep of Test::Exception) requires 5.6.0
208 - Removed error()/clear_error()
209 - All error-handling is done with die()
210 - Broke out DBM::Deep's code into DBM::Deep::Engine
211 - Tied variables can no longer be assigned to a DBM::Deep object.
212 - This includes cross-file assignments.
213 - Autovivification now works
214 - This is a consequence of the fact that all assignments are tied.
215 - set_pack() and set_digest() have been removed.
216 - Instead, you will now pass the appropriate values into new()
217 - A pack_size parameter has been added to make 64-bit files easier
218 - Transactions now work
220 0.983 Apr 10 20:00:00 2006 Pacific
221 - Added patch inspired by Jeff Janes (Thanks!)
222 - Autovivification now works correctly
223 - The following now works correctly
224 my %hash = ( a => 1 );
225 $db->{hash} = \%hash;
227 cmp_ok( $db->{hash}{b}, '==', 2 );
228 - (RT#18530) - DBM::Deep now plays nicely with -l
230 0.982 Mar 08 11:00:00 2006 Pacific
231 - Fixed smoketests that were failing on Win32
232 - Added restriction for Perl 5.6.0 or higher.
233 - Digest::MD5 and Sub::Uplevel (dep of Test::Exception) require 5.6+
235 0.981 Mar 06 11:00:00 2006 Pacific
236 - (RT#17947) - Fixed test that was failing on older Perls
238 0.98 Feb 28 11:00:00 2006 Pacific
239 - Added in patch by David Cantrell to allow use of DATA filehandle
240 - Fixed bug where attempting to export() a structure that used autobless would die
241 - Fixed arraytest slowness by localizing $SIG{__DIE__} to prevent Test::Builder's
242 $SIG{__DIE__} from being called. (q.v. http://perldoc.perl.org/functions/eval.html)
243 - More methods have been made private:
244 - root() is now _root()
245 - base_offset() is now _base_offset()
247 - type() is now _type()
248 - precalc_sizes() is now _precalc_sizes()
250 0.97 Feb 24 10:00:00 2006 Pacific
251 - Reorganization of distribution to a more standard layout
252 - Migration to Module::Build with EU::MM backwards compatibility
253 - Migration of all tests to use Test::More and Test::Exception
254 - Added Devel::Cover report to DBM::Deep POD
255 - Test coverage improved to 89.6% (and climbing)
256 - The following methods have been renamed to reflect their private nature:
257 - init() is now _init()
258 - open() is now _open()
259 - close() is now _close()
260 - load_tag() is now _load_tag()
261 - index_lookup() is now _index_lookup()
262 - add_bucket() is now _add_bucket()
263 - get_bucket_value() is now _get_bucket_value()
264 - delete_bucket() is now _delete_bucket()
265 - bucket_exists() is now _bucket_exists()
266 - find_bucket_list() is now _find_bucket_list()
267 - traverse_index() is now _traverse_index()
268 - get_next_key() is now _get_next_key()
269 - copy_node() is now _copy_node()
270 - throw_error() is now _throw_error()
271 - The various tied classes have been broken out. This means that testing
272 "ref( $obj ) eq 'DBM::Deep'" will now fail. The correct test is
273 "eval { $obj->isa( 'DBM::Deep' ) }".
274 - The various methods like push and delete now have the same return values as
275 the standard builtins.
276 - TIEARRAY and TIEHASH now check their parameters more thoroughly
277 - Negative indices for arrays works as expected, including throwing the appropriate
279 - RT #16877 is fixed (DBM::Deep broken with Perl 5.9.3+).
280 - RT #14893 is fixed (tie() and new() use different parameter lists).
281 - A bug with optimize and threading is fixed.
282 - autobless has received some attention, resulting in a number of bugs fixed.
283 - Removed mode option as it just caused confusion.
284 - Removed volatile option as it is pretty useless (use locking instead)
285 - Locking now implicitly enables autoflush
287 0.96 Oct 14 09:55:00 2005 Pacific
288 - Fixed build (OS X hidden files killed it)
289 - You can now pass in an optional filehandle to the constructor
291 0.95 Oct 12 13:58:00 2005 Pacific
292 - Added optional autobless flag to preserve and restore blessed hashes
293 - Fixed bug where 0 could not be fetched using get_next_key
294 - Fixed bug where tie() constructor didn't accept a hash ref for args
295 - optimize() now preserves user/group/permissions
296 - Errors are now FATAL (meaning it calls die()), unless you set debug flag
298 0.94 Apr 13 19:00:26 2004 Pacific
299 - Fixed bug reported by John Cardenas (corruption at key level when
300 replace of less data was done on bucket)
302 0.93 Feb 15 19:53:17 2004 Pacific
303 - Fixed optmize() on Win32 where orig file couldn't be overwritten unless
304 filehandle was closed first. This change introduces a potential race
305 condition when using locking and optmize() on Win32, but it can be
306 fixed in the future using a soft copy instead of Perl's rename().
308 0.92 Feb 12 19:10:22 2004 Pacific
309 - Fixed bug where passing a reference to a different DBM::Deep object
310 would still result in an internal reference.
311 - Added export() method for recursively extracting hashes/arrays into
312 standard in-memory Perl structures.
313 - Added import() method for recursively importing existing Perl hash/
315 - Fixed bug where optimize() wouldn't work if base level of DB was
316 an array instead of a hash.
318 0.91 Feb 12 02:30:22 2004 Pacific
319 - Fixed bug with splice() when length of removed section was 0
320 - Updated POD re: circular refs and optimize()
321 - Had to jump version numbers to 0.91 because in previous releases
322 I used only a single digit after the decimal which was confusing
325 0.10 Feb 11 08:58:35 2004 Pacific
326 - Fixed bug where default file mode was CLEARING files (Thanks Rich!)
327 - Added experimental support for circular references
328 - Fixed bugs in shift(), unshift() and splice() where nested objects
329 in array would be recursively re-stored as basic hashes/arrays
330 - Fixed typos in POD docs
332 0.9 Feb 10 03:25:48 2004 Pacific
333 - Added Filters for storing/fetching keys/values
334 - Added hook for supplying own hashing algorithm
335 - FIxed some typos in POD docs, added new sections
337 0.8 Feb 8 02:38:22 2004 Pacific
338 - Renamed to DBM::Deep for CPAN
339 - Added optimize() method for rekindling unused space
340 - Now returning hybrid tie()/OO object from new()
341 - Basic error handling introduced
342 - Added debug mode for printing errors to STDERR
343 - Added TYPE_HASH and TYPE_ARRAY constants for "type" param
344 - Added clone() method for safe copying of objects
345 - Wrote POD documentation
346 - Added set_pack() function for manipulating LONG_SIZE / LONG_PACK
347 - Added aliases for most tied functions for public use
348 - Now setting binmode() on FileHandle for Win32
349 - Added 45 unit tests
351 0.7 Jan 4 11:31:50 2003 UTC
353 - Changed file signature to DPDB (not compatible with older versions)
354 - Converted array length to packed long instead of sprintf()ed string
356 0.6 Dec 31 15:12:03 2002 UTC
357 - Some misc optimizations for speed
359 0.5 Oct 18 08:55:29 2002 UTC
360 - support for force_return_next parameter in traverse_index() method for
361 ultra-fast combined key search/removal
363 0.4 Oct 15 20:07:47 2002 UTC
364 - now making sure filehandle is open for all DB calls
366 0.3 Oct 3 19:04:13 2002 UTC
367 - fixed bug that could cause corrupted data when using locking
369 0.2 Aug 6 16:37:32 2002 UTC
370 - Removed base index caching, as it can cause problems when two processes
371 are populating the db at the same time (even with locking)
373 0.1 Jun 3 08:06:26 2002 UTC
