26f89086 31.0002 Sep 20 22:00:00 2007 EDT
4 - (This version is compatible with 1.0001)
5 - Expanded _throw_error() so that it provides better information.
6 (Thanks brian d foy!)
7 - Fixed how shift, unshift, and splice work when there are references
8 being moved. It now no longer dies.
9 - Added diag in t/17_import.t to note that the failing tests on blead
10 are due to Clone being broken, not DBM::Deep. The tests will still
11 fail because I don't want users to install something that's broken
12 and deal with those bug reports.

fbd470e4 141.0001 Mar 12 16:15:00 2007 EDT
15 - (This version is compatible with 1.0000)
16 - Added a missing dependency on IO::Scalar (RT #25387)
17 - Fixed how t/44_upgrade_db.t and utils/upgrade_db.pl worked
18 - utils/upgrade_db.pl now uses #!perl, not #!/usr/bin/perl
19 - t/44_upgrade_db.t now explicitly calls $^X
20 (Thanks merlyn!)

221.0000 Feb 26 22:30:00 2007 EST
f72b2dfb 23 - THIS VERSION IS INCOMPATIBLE WITH FILES FROM ALL OTHER PRIOR VERSIONS.
24 - To aid in this form of upgrades, DBM::Deep now checks the file format
25 version to make sure that it knows how to read it.
26 - db_upgrade.pl was added to utils/. This will -NOT- install onto
27 your system. This is deliberate.
28 - db_upgrade.pl will not handle developer release file formats. This
29 is due to the fact that all developer releases in preparation for a
30 given release share the same file version, even though the file
31 format may change. This is deliberate.
32 - Importing no longer takes place within a transaction
33 - The following parameters were added:
34 - data_sector_size - this determines the default size of a data sector.
35 - Correctly handle opening readonly files
36
fbd470e4 370.99_04 Jan 24 22:30:00 2007 EST
b48ae6ec 38 - Added the missing lib/DBM/Deep.pod file to the MANIFEST
39 - Fixed a poorly-designed test that was failing depending on what Clone::Any
f72b2dfb 40 was using.
b48ae6ec 41 - All "use 5.6.0;" lines are now "use 5.006_000;" to avoid warnings about
f72b2dfb 42 unsupported vstrings in 5.9.x
b48ae6ec 43
fbd470e4 440.99_03 Jan 23 22:30:00 2007 EST
9a63e1f2 45 - THIS VERSION IS INCOMPATIBLE WITH FILES FROM ALL OTHER PRIOR VERSIONS.
46 - The fileformat changed completely. I will be writing a converter, but
47 it's not there right now. Do NOT expect that this module will
48 correctly detect older versions and handle them sanely. Sanity will be
49 there for 1.00, but we're not there yet, are we?
a8fdabda 50 - Converted to use FileHandle::Fmode to handle filehandle status checks
13ff93d5 51 - Fixed bug with deleting already-deleted items on Win32 (reported by Nigel Sandever)
9a63e1f2 52 - The guts of how transactions work has been rewritten to better handle
53 some edgecases. This required a complete rewrite of the engine.
54 - Freespace management is now in place. It's not perfect, but it's there.
55 - The rewrite of the engine required a rewrite of how first_key/next_key
56 was implemented. This should result in significant speed improvements.
57 - Self-reference has been removed. This means you cannot do:
58 $db->{foo} = { x => 'y' };
59 $db->{bar} = $db->{foo};
60 I hope to be able to return this functionality by 1.00, but I cannot
61 promise anything. To do this properly, it requires refcounting in order
62 to correctly handle deletions and transactions. Once you move away from
63 a simple tree, everything becomes really hard.
a8fdabda 64
c8602313 650.99_02 Apr 28 05:00:00 2006 Pacific
66 - Added missing file to the MANIFEST
67
680.99_01 Apr 27 18:00:00 2006 Pacific
d2aefba0 69 - Added explicit dependency on Perl 5.6.0
e06824f8 70 - Digest::MD5 requires 5.6.0
71 - Sub::Uplevel (dep of Test::Exception) requires 5.6.0
95967a5e 72 - Removed error()/clear_error()
d2aefba0 73 - All error-handling is done with die()
e06824f8 74 - Broke out DBM::Deep's code into DBM::Deep::Engine
d2aefba0 75 - Tied variables can no longer be assigned to a DBM::Deep object.
76 - This includes cross-file assignments.
77 - Autovivification now works
78 - This is a consequence of the fact that all assignments are tied.
79 - set_pack() and set_digest() have been removed.
80 - Instead, you will now pass the appropriate values into new()
81 - A pack_size parameter has been added to make 64-bit files easier
c8602313 82 - Transactions now work
95967a5e 83
a8fdabda 840.983 Apr 10 20:00:00 2006 Pacific
85 - Added patch inspired by Jeff Janes (Thanks!)
86 - Autovivification now works correctly
87 - The following now works correctly
88 my %hash = ( a => 1 );
89 $db->{hash} = \%hash;
90 $hash{b} = 2;
91 cmp_ok( $db->{hash}{b}, '==', 2 );
92 - (RT#18530) - DBM::Deep now plays nicely with -l
93
940.982 Mar 08 11:00:00 2006 Pacific
95 - Fixed smoketests that were failing on Win32
96 - Added restriction for Perl 5.6.0 or higher.

101
9be51a89 1020.98 Feb 28 11:00:00 2006 Pacific
a8bd842e 103 - Added in patch by David Cantrell to allow use of DATA filehandle
bcbe5355 104 - Fixed bug where attempting to export() a structure that used autobless would die
e3cb84dc 105 - Fixed arraytest slowness by localizing $SIG{__DIE__} to prevent Test::Builder's
106 $SIG{__DIE__} from being called. (q.v. http://perldoc.perl.org/functions/eval.html)
4d35d856 107 - More methods have been made private:
108 - root() is now _root()

e096f245 117 - Migration of all tests to use Test::More and Test::Exception
118 - Added Devel::Cover report to DBM::Deep POD
119 - Test coverage improved to 89.6% (and climbing)
8b957036 120 - The following methods have been renamed to reflect their private nature:
121 - init() is now _init()
14a3acb6 122 - open() is now _open()
0207d648 123 - close() is now _close()
261d1296 124 - load_tag() is now _load_tag()
125 - index_lookup() is now _index_lookup()
126 - add_bucket() is now _add_bucket()
127 - get_bucket_value() is now _get_bucket_value()
128 - delete_bucket() is now _delete_bucket()
129 - bucket_exists() is now _bucket_exists()
130 - find_bucket_list() is now _find_bucket_list()
131 - traverse_index() is now _traverse_index()
132 - get_next_key() is now _get_next_key()
133 - copy_node() is now _copy_node()
134 - throw_error() is now _throw_error()
217fef02 135 - The various tied classes have been broken out. This means that testing
136 "ref( $obj ) eq 'DBM::Deep'" will now fail. The correct test is
137 "eval { $obj->isa( 'DBM::Deep' ) }".
138 - The various methods like push and delete now have the same return values as
139 the standard builtins.
9d085683 140 - TIEARRAY and TIEHASH now check their parameters more thoroughly
e096f245 141 - Negative indices for arrays works as expected, including throwing the appropriate
142 errors.
26138c00 143 - RT #16877 is fixed (DBM::Deep broken with Perl 5.9.3+).
144 - RT #14893 is fixed (tie() and new() use different parameter lists).
145 - A bug with optimize and threading is fixed.
146 - autobless has received some attention, resulting in a number of bugs fixed.
90f93b43 147 - Removed mode option as it just caused confusion.
3ea61317 148 - Removed volatile option as it is pretty useless (use locking instead)
149 - Locking now implicitly enables autoflush
ffed8b01 150
1510.96 Oct 14 09:55:00 2005 Pacific
152 - Fixed build (OS X hidden files killed it)
153 - You can now pass in an optional filehandle to the constructor
154
1550.95 Oct 12 13:58:00 2005 Pacific
156 - Added optional autobless flag to preserve and restore blessed hashes
157 - Fixed bug where 0 could not be fetched using get_next_key
158 - Fixed bug where tie() constructor didn't accept a hash ref for args
159 - optimize() now preserves user/group/permissions
160 - Errors are now FATAL (meaning it calls die()), unless you set debug flag
161
1620.94 Apr 13 19:00:26 2004 Pacific
163 - Fixed bug reported by John Cardenas (corruption at key level when
164 replace of less data was done on bucket)
165
1660.93 Feb 15 19:53:17 2004 Pacific
167 - Fixed optmize() on Win32 where orig file couldn't be overwritten unless
168 filehandle was closed first. This change introduces a potential race
169 condition when using locking and optmize() on Win32, but it can be
170 fixed in the future using a soft copy instead of Perl's rename().
171
1720.92 Feb 12 19:10:22 2004 Pacific
173 - Fixed bug where passing a reference to a different DBM::Deep object
174 would still result in an internal reference.
175 - Added export() method for recursively extracting hashes/arrays into
176 standard in-memory Perl structures.
177 - Added import() method for recursively importing existing Perl hash/
178 array structures
179 - Fixed bug where optimize() wouldn't work if base level of DB was
180 an array instead of a hash.
181
1820.91 Feb 12 02:30:22 2004 Pacific
183 - Fixed bug with splice() when length of removed section was 0
184 - Updated POD re: circular refs and optimize()
185 - Had to jump version numbers to 0.91 because in previous releases
186 I used only a single digit after the decimal which was confusing
187 the CPAN indexer.
188
1890.10 Feb 11 08:58:35 2004 Pacific
190 - Fixed bug where default file mode was CLEARING files (Thanks Rich!)
191 - Added experimental support for circular references
192 - Fixed bugs in shift(), unshift() and splice() where nested objects
193 in array would be recursively re-stored as basic hashes/arrays
194 - Fixed typos in POD docs
195
1960.9 Feb 10 03:25:48 2004 Pacific
197 - Added Filters for storing/fetching keys/values
198 - Added hook for supplying own hashing algorithm
199 - FIxed some typos in POD docs, added new sections
200
2010.8 Feb 8 02:38:22 2004 Pacific
202 - Renamed to DBM::Deep for CPAN
203 - Added optimize() method for rekindling unused space
204 - Now returning hybrid tie()/OO object from new()
205 - Basic error handling introduced
206 - Added debug mode for printing errors to STDERR
207 - Added TYPE_HASH and TYPE_ARRAY constants for "type" param
208 - Added clone() method for safe copying of objects
209 - Wrote POD documentation
210 - Added set_pack() function for manipulating LONG_SIZE / LONG_PACK
211 - Added aliases for most tied functions for public use
212 - Now setting binmode() on FileHandle for Win32
213 - Added 45 unit tests
214
2150.7 Jan 4 11:31:50 2003 UTC
216 - Renamed to DeepDB
217 - Changed file signature to DPDB (not compatible with older versions)
218 - Converted array length to packed long instead of sprintf()ed string
219
2200.6 Dec 31 15:12:03 2002 UTC
221 - Some misc optimizations for speed
222
2230.5 Oct 18 08:55:29 2002 UTC
224 - support for force_return_next parameter in traverse_index() method for
225 ultra-fast combined key search/removal
226
2270.4 Oct 15 20:07:47 2002 UTC
228 - now making sure filehandle is open for all DB calls
229
2300.3 Oct 3 19:04:13 2002 UTC
231 - fixed bug that could cause corrupted data when using locking
232
2330.2 Aug 6 16:37:32 2002 UTC
234 - Removed base index caching, as it can cause problems when two processes
235 are populating the db at the same time (even with locking)
236
2370.1 Jun 3 08:06:26 2002 UTC
238 - initial release
