1 Revision history for DBM::Deep.
3 1.0010 May 27 12:00:00 2008 EST
4 - (This version is compatible with 1.0009)
5 - Fix for RT#35140 (invalid POD links)
6 - Fix for RT#34819 (Cannot assign the same value back to the same location)
7 - Fix for RT#29957 (Cannot assign the same value back to the same location)
8 - Fix for RT#33863 (Cannot shift an arrayref from an array)
9 - When something is deleted from a DB, the value is export()ed, allowing it
11 - This exporting is only done if the refcount == 0 after the deletion.
13 1.0009 Mar 19 12:00:00 2008 EDT
14 - (This version is compatible with 1.0008)
15 - Internal refactorings to prepare for some optimizations.
16 - _fh() has been removed. It was marked as private, so don't complain.
17 - Skip a test that was spuriously failing on Win32 (Thanks, Alias!)
19 1.0008 Mar 09 20:00:00 2008 EDT
20 - (This version is compatible with 1.0007)
21 - Fixed a number of Win32 issues (Reported by Steven Samelson - thank you!)
22 - Much thanks to Nigel Sandever and David Golden for their help
23 debugging the issues, particularly with DBM::Deep's usage of
24 File::Temp (which removes a number of warnings).
25 - Autovivification now works on Win32. It turns out that when a
26 process takes a shared flock on a file, it's not allowed to write to
27 it under Win32, unlike *nix. This is probably a good catch.
28 - Note: The fix is a hack. All locks are now exclusive until a
31 1.0007 Jan 10 00:00:00 2008 EDT
32 - (This version is compatible with 1.0006)
33 - Applied a patch+failing test submitted by sprout@cpan.org. Thanks!
34 - Turns out that the case of 17 keys with the same first character in the
35 MD5 hash wasn't being tested for. This was a crashbug.
36 - A fix has been made to upgrade_db.pl (RT# 30067)
37 - The version determinations were in the wrong order or evaluation. This
38 meant that upgrade_db.pl wouldn't work as expected (or at all).
39 - Added a minimum Pod::Usage requirement (RT# 29976)
40 - It's an optional item in Build.PL
41 - utils/upgrade_db.pl now checks for that version, as does the test.
43 1.0006 Oct 01 23:15:00 2007 EDT
44 - (This version is compatible with 1.0005)
45 - Removed Clone and replaced it with a hand-written datastructure walker.
46 - This greatly reduces the footprint of a large import
47 - This bypasses a failure of Clone under Perl 5.9.5
48 - Moved t/37_delete_edge_cases.t to t_attic because it wasn't really used
49 - import() has a stricter API now. This is a potentially incompatible API
50 change. Only HASH and ARRAY refs are now allowed and they must match the type
51 of the object being imported into.
53 1.0005 Oct 01 11:15:00 2007 EDT
54 - (This version is compatible with 1.0004)
55 - Added proper singleton support. This means that the following now works:
56 $db->{foo} = [ 1 .. 3];
59 is( $x, $y ); # Now passes
60 - This means that Data::Dumper now properly reports when $db->{foo} = $db->{bar}
62 1.0004 Sep 28 12:15:00 2007 EDT
63 - (This version is compatible with 1.0003)
64 - Fixed the Changes file (wrong version was displayed for 1.0003)
65 - Added filter sugar methods to be more API-compatible with other DBMs
66 - This was added to support a patch provided to IO::All so it can
67 use DBM::Deep as a DBM provider.
68 - Implemented _dump_file in order to display the file structure. As a
69 result, the following bugs were fixed:
70 - Arrays and hashes now clean up after themselves better.
71 - Bucketlists now clean up after themselves better.
72 - Reindexing properly clears the old bucketlist before freeing it.
74 1.0003 Sep 24 14:00:00 2007 EDT
75 - THIS VERSION IS INCOMPATIBLE WITH FILES FROM ALL OTHER PRIOR VERSIONS.
76 - Further fixes for unshift/shift/splice and references (RT# 29583)
77 - To fix that, I had to put support for real references in.
78 - the 16 and 22 tests are now re-enabled.
79 - Yes, this means that real references work. See t/45_references.t
81 1.0002 Sep 20 22:00:00 2007 EDT
82 - (This version is compatible with 1.0001)
83 - Expanded _throw_error() so that it provides better information.
85 - Fixed how shift, unshift, and splice work when there are references
86 being moved. It now no longer dies.
87 - Added diag in t/17_import.t to note that the failing tests on blead
88 are due to Clone being broken, not DBM::Deep. The tests will still
89 fail because I don't want users to install something that's broken
90 and deal with those bug reports.
92 1.0001 Mar 12 16:15:00 2007 EDT
93 - (This version is compatible with 1.0000)
94 - Added a missing dependency on IO::Scalar (RT #25387)
95 - Fixed how t/44_upgrade_db.t and utils/upgrade_db.pl worked
96 - utils/upgrade_db.pl now uses #!perl, not #!/usr/bin/perl
97 - t/44_upgrade_db.t now explicitly calls $^X
100 1.0000 Feb 26 22:30:00 2007 EST
101 - THIS VERSION IS INCOMPATIBLE WITH FILES FROM ALL OTHER PRIOR VERSIONS.
102 - To aid in this form of upgrades, DBM::Deep now checks the file format
103 version to make sure that it knows how to read it.
104 - db_upgrade.pl was added to utils/. This will -NOT- install onto
105 your system. This is deliberate.
106 - db_upgrade.pl will not handle developer release file formats. This
107 is due to the fact that all developer releases in preparation for a
108 given release share the same file version, even though the file
109 format may change. This is deliberate.
110 - Importing no longer takes place within a transaction
111 - The following parameters were added:
112 - data_sector_size - this determines the default size of a data sector.
113 - Correctly handle opening readonly files
115 0.99_04 Jan 24 22:30:00 2007 EST
116 - Added the missing lib/DBM/Deep.pod file to the MANIFEST
117 - Fixed a poorly-designed test that was failing depending on what Clone::Any
119 - All "use 5.6.0;" lines are now "use 5.006_000;" to avoid warnings about
120 unsupported vstrings in 5.9.x
122 0.99_03 Jan 23 22:30:00 2007 EST
123 - THIS VERSION IS INCOMPATIBLE WITH FILES FROM ALL OTHER PRIOR VERSIONS.
124 - The fileformat changed completely. I will be writing a converter, but
125 it's not there right now. Do NOT expect that this module will
126 correctly detect older versions and handle them sanely. Sanity will be
127 there for 1.00, but we're not there yet, are we?
128 - Converted to use FileHandle::Fmode to handle filehandle status checks
129 - Fixed bug with deleting already-deleted items on Win32 (reported by Nigel Sandever)
130 - The guts of how transactions work has been rewritten to better handle
131 some edgecases. This required a complete rewrite of the engine.
132 - Freespace management is now in place. It's not perfect, but it's there.
133 - The rewrite of the engine required a rewrite of how first_key/next_key
134 was implemented. This should result in significant speed improvements.
135 - Self-reference has been removed. This means you cannot do:
136 $db->{foo} = { x => 'y' };
137 $db->{bar} = $db->{foo};
138 I hope to be able to return this functionality by 1.00, but I cannot
139 promise anything. To do this properly, it requires refcounting in order
140 to correctly handle deletions and transactions. Once you move away from
141 a simple tree, everything becomes really hard.
143 0.99_02 Apr 28 05:00:00 2006 Pacific
144 - Added missing file to the MANIFEST
146 0.99_01 Apr 27 18:00:00 2006 Pacific
147 - Added explicit dependency on Perl 5.6.0
148 - Digest::MD5 requires 5.6.0
149 - Sub::Uplevel (dep of Test::Exception) requires 5.6.0
150 - Removed error()/clear_error()
151 - All error-handling is done with die()
152 - Broke out DBM::Deep's code into DBM::Deep::Engine
153 - Tied variables can no longer be assigned to a DBM::Deep object.
154 - This includes cross-file assignments.
155 - Autovivification now works
156 - This is a consequence of the fact that all assignments are tied.
157 - set_pack() and set_digest() have been removed.
158 - Instead, you will now pass the appropriate values into new()
159 - A pack_size parameter has been added to make 64-bit files easier
160 - Transactions now work
162 0.983 Apr 10 20:00:00 2006 Pacific
163 - Added patch inspired by Jeff Janes (Thanks!)
164 - Autovivification now works correctly
165 - The following now works correctly
166 my %hash = ( a => 1 );
167 $db->{hash} = \%hash;
169 cmp_ok( $db->{hash}{b}, '==', 2 );
170 - (RT#18530) - DBM::Deep now plays nicely with -l
172 0.982 Mar 08 11:00:00 2006 Pacific
173 - Fixed smoketests that were failing on Win32
174 - Added restriction for Perl 5.6.0 or higher.
175 - Digest::MD5 and Sub::Uplevel (dep of Test::Exception) require 5.6+
177 0.981 Mar 06 11:00:00 2006 Pacific
178 - (RT#17947) - Fixed test that was failing on older Perls
180 0.98 Feb 28 11:00:00 2006 Pacific
181 - Added in patch by David Cantrell to allow use of DATA filehandle
182 - Fixed bug where attempting to export() a structure that used autobless would die
183 - Fixed arraytest slowness by localizing $SIG{__DIE__} to prevent Test::Builder's
184 $SIG{__DIE__} from being called. (q.v. http://perldoc.perl.org/functions/eval.html)
185 - More methods have been made private:
186 - root() is now _root()
187 - base_offset() is now _base_offset()
189 - type() is now _type()
190 - precalc_sizes() is now _precalc_sizes()
192 0.97 Feb 24 10:00:00 2006 Pacific
193 - Reorganization of distribution to a more standard layout
194 - Migration to Module::Build with EU::MM backwards compatibility
195 - Migration of all tests to use Test::More and Test::Exception
196 - Added Devel::Cover report to DBM::Deep POD
197 - Test coverage improved to 89.6% (and climbing)
198 - The following methods have been renamed to reflect their private nature:
199 - init() is now _init()
200 - open() is now _open()
201 - close() is now _close()
202 - load_tag() is now _load_tag()
203 - index_lookup() is now _index_lookup()
204 - add_bucket() is now _add_bucket()
205 - get_bucket_value() is now _get_bucket_value()
206 - delete_bucket() is now _delete_bucket()
207 - bucket_exists() is now _bucket_exists()
208 - find_bucket_list() is now _find_bucket_list()
209 - traverse_index() is now _traverse_index()
210 - get_next_key() is now _get_next_key()
211 - copy_node() is now _copy_node()
212 - throw_error() is now _throw_error()
213 - The various tied classes have been broken out. This means that testing
214 "ref( $obj ) eq 'DBM::Deep'" will now fail. The correct test is
215 "eval { $obj->isa( 'DBM::Deep' ) }".
216 - The various methods like push and delete now have the same return values as
217 the standard builtins.
218 - TIEARRAY and TIEHASH now check their parameters more thoroughly
219 - Negative indices for arrays works as expected, including throwing the appropriate
221 - RT #16877 is fixed (DBM::Deep broken with Perl 5.9.3+).
222 - RT #14893 is fixed (tie() and new() use different parameter lists).
223 - A bug with optimize and threading is fixed.
224 - autobless has received some attention, resulting in a number of bugs fixed.
225 - Removed mode option as it just caused confusion.
226 - Removed volatile option as it is pretty useless (use locking instead)
227 - Locking now implicitly enables autoflush
229 0.96 Oct 14 09:55:00 2005 Pacific
230 - Fixed build (OS X hidden files killed it)
231 - You can now pass in an optional filehandle to the constructor
233 0.95 Oct 12 13:58:00 2005 Pacific
234 - Added optional autobless flag to preserve and restore blessed hashes
235 - Fixed bug where 0 could not be fetched using get_next_key
236 - Fixed bug where tie() constructor didn't accept a hash ref for args
237 - optimize() now preserves user/group/permissions
238 - Errors are now FATAL (meaning it calls die()), unless you set debug flag
240 0.94 Apr 13 19:00:26 2004 Pacific
241 - Fixed bug reported by John Cardenas (corruption at key level when
242 replace of less data was done on bucket)
244 0.93 Feb 15 19:53:17 2004 Pacific
245 - Fixed optmize() on Win32 where orig file couldn't be overwritten unless
246 filehandle was closed first. This change introduces a potential race
247 condition when using locking and optmize() on Win32, but it can be
248 fixed in the future using a soft copy instead of Perl's rename().
250 0.92 Feb 12 19:10:22 2004 Pacific
251 - Fixed bug where passing a reference to a different DBM::Deep object
252 would still result in an internal reference.
253 - Added export() method for recursively extracting hashes/arrays into
254 standard in-memory Perl structures.
255 - Added import() method for recursively importing existing Perl hash/
257 - Fixed bug where optimize() wouldn't work if base level of DB was
258 an array instead of a hash.
260 0.91 Feb 12 02:30:22 2004 Pacific
261 - Fixed bug with splice() when length of removed section was 0
262 - Updated POD re: circular refs and optimize()
263 - Had to jump version numbers to 0.91 because in previous releases
264 I used only a single digit after the decimal which was confusing
267 0.10 Feb 11 08:58:35 2004 Pacific
268 - Fixed bug where default file mode was CLEARING files (Thanks Rich!)
269 - Added experimental support for circular references
270 - Fixed bugs in shift(), unshift() and splice() where nested objects
271 in array would be recursively re-stored as basic hashes/arrays
272 - Fixed typos in POD docs
274 0.9 Feb 10 03:25:48 2004 Pacific
275 - Added Filters for storing/fetching keys/values
276 - Added hook for supplying own hashing algorithm
277 - FIxed some typos in POD docs, added new sections
279 0.8 Feb 8 02:38:22 2004 Pacific
280 - Renamed to DBM::Deep for CPAN
281 - Added optimize() method for rekindling unused space
282 - Now returning hybrid tie()/OO object from new()
283 - Basic error handling introduced
284 - Added debug mode for printing errors to STDERR
285 - Added TYPE_HASH and TYPE_ARRAY constants for "type" param
286 - Added clone() method for safe copying of objects
287 - Wrote POD documentation
288 - Added set_pack() function for manipulating LONG_SIZE / LONG_PACK
289 - Added aliases for most tied functions for public use
290 - Now setting binmode() on FileHandle for Win32
291 - Added 45 unit tests
293 0.7 Jan 4 11:31:50 2003 UTC
295 - Changed file signature to DPDB (not compatible with older versions)
296 - Converted array length to packed long instead of sprintf()ed string
298 0.6 Dec 31 15:12:03 2002 UTC
299 - Some misc optimizations for speed
301 0.5 Oct 18 08:55:29 2002 UTC
302 - support for force_return_next parameter in traverse_index() method for
303 ultra-fast combined key search/removal
305 0.4 Oct 15 20:07:47 2002 UTC
306 - now making sure filehandle is open for all DB calls
308 0.3 Oct 3 19:04:13 2002 UTC
309 - fixed bug that could cause corrupted data when using locking
311 0.2 Aug 6 16:37:32 2002 UTC
312 - Removed base index caching, as it can cause problems when two processes
313 are populating the db at the same time (even with locking)
315 0.1 Jun 3 08:06:26 2002 UTC
