10 | |
11 | Backport to 5.6.1 by Ilya Martynov <ilya@martynov.org>. |

13 | =item 2.11 (unreleased) |
14 | |
15 | C<0> is now dumped as such, not as C<'0'>. |
16 | |
17 | qr// objects are now dumped correctly (provided a post-5.005_58) |
18 | overload.pm exists). |
19 | |
20 | Implemented $Data::Dumper::Maxdepth, which was on the Todo list. |
21 | Thanks to John Nolan <jpnolan@Op.Net>. |
22 | |
23 | =item 2.101 (30 Apr 1999) |
24 | |
25 | Minor release to sync with version in 5.005_03. Fixes dump of |
26 | dummy coderefs. |

28 | =item 2.10 (31 Oct 1998) |
29 | |
30 | Bugfixes for dumping related undef values, globs, and better double |
31 | quoting: three patches suggested by Gisle Aas <gisle@aas.no>. |
32 | |
33 | Escaping of single quotes in the XS version could get tripped up |
34 | by the presence of nulls in the string. Fix suggested by |
35 | Slaven Rezic <eserte@cs.tu-berlin.de>. |
36 | |
37 | Rather large scale reworking of the logic in how seen values |
38 | are stashed. Anonymous scalars that may be encountered while |
39 | traversing the structure are properly tracked, in case they become |
40 | used in data dumped in a later pass. There used to be a problem |
41 | with the previous logic that prevented such structures from being |
42 | dumped correctly. |
43 | |
44 | Various additions to the testsuite. |

46 | =item 2.09 (9 July 1998) |
47 | |
48 | Implement $Data::Dumper::Bless, suggested by Mark Daku <daku@nortel.ca>. |
49 | |
50 | =item 2.081 (15 January 1998) |
51 | |
52 | Minor release to fix Makefile.PL not accepting MakeMaker args. |
53 | |
54 | =item 2.08 (7 December 1997) |
55 | |
56 | Glob dumps don't output superflous 'undef' anymore. |
57 | |
58 | Fixes from Gisle Aas <gisle@aas.no> to make Dumper() work with |
59 | overloaded strings in recent perls, and his new testsuite. |
60 | |
61 | require 5.004. |
62 | |
63 | A separate flag to always quote hash keys (on by default). |
64 | |
65 | Recreating known CODE refs is now better supported. |
66 | |
67 | Changed flawed constant SCALAR bless workaround. |
68 | |
69 | =item 2.07 (7 December 1996) |
70 | |
71 | Dumpxs output is now exactly the same as Dump. It still doesn't |
72 | honor C<Useqq> though. |
73 | |
74 | Regression tests test for identical output and C<eval>-ability. |
75 | |
76 | Bug in *GLOB{THING} output fixed. |
77 | |
78 | Other small enhancements. |
79 | |
80 | =item 2.06 (2 December 1996) |
81 | |
82 | Bugfix that was serious enough for new release--the bug cripples |
83 | MLDBM. Problem was "Attempt to modify readonly value..." failures |
84 | that stemmed for a misguided SvPV_force() instead of a SvPV().) |
85 | |
86 | =item 2.05 (2 December 1996) |
87 | |
88 | Fixed the type mismatch that was causing Dumpxs test to fail |
89 | on 64-bit platforms. |
90 | |
91 | GLOB elements are dumped now when C<Purity> is set (using the |
92 | *GLOB{THING} syntax). |
93 | |
94 | The C<Freezer> option can be set to a method name to call |
95 | before probing objects for dumping. Some applications: objects with |
96 | external data, can re-bless themselves into a transitional package; |
97 | Objects the maintain ephemeral state (like open files) can put |
98 | additional information in the object to facilitate persistence. |
99 | |
100 | The corresponding C<Toaster> option, if set, specifies |
101 | the method call that will revive the frozen object. |
102 | |
103 | The C<Deepcopy> flag has been added to do just that. |
104 | |
105 | Dumper does more aggressive cataloging of SCALARs encountered |
106 | within ARRAY/HASH structures. Thanks to Norman Gaywood |
107 | <norm@godel.une.edu.au> for reporting the problem. |
108 | |
109 | Objects that C<overload> the '""' operator are now handled |
110 | properly by the C<Dump> method. |
111 | |
112 | Significant additions to the testsuite. |
113 | |
114 | More documentation. |
115 | |
116 | =item 2.04beta (28 August 1996) |
117 | |
118 | Made dump of glob names respect C<Useqq> setting. |
119 | |
120 | [@$%] are now escaped now when in double quotes. |
121 | |
122 | =item 2.03beta (26 August 1996) |
123 | |
124 | Fixed Dumpxs. It was appending trailing nulls to globnames. |
125 | (reported by Randal Schwartz <merlyn@teleport.com>). |
126 | |
127 | Calling the C<Indent()> method on a dumper object now correctly |
128 | resets the internal separator (reported by Curt Tilmes |
129 | <curt@ltpmail.gsfc.nasa.gov>). |
130 | |
131 | New C<Terse> option to suppress the 'C<VARI<n> = >' prefix |
132 | introduced. If the option is set, they are output only when |
133 | absolutely essential. |
134 | |
135 | The C<Useqq> flag is supported (but not by the XSUB version |
136 | yet). |
137 | |
138 | Embedded nulls in keys are now handled properly by Dumpxs. |
139 | |
140 | Dumper.xs now use various integer types in perl.h (should |
141 | make it compile without noises on 64 bit platforms, although |
142 | I haven't been able to test this). |
143 | |
144 | All the dump methods now return a list of strings in a list |
145 | context. |
146 | |
147 | |
148 | =item 2.02beta (13 April 1996) |
149 | |
150 | Non portable sprintf usage in XS code fixed (thanks to |
151 | Ulrich Pfeifer <pfeifer@charly.informatik.uni-dortmund.de>). |
152 | |
153 | |
154 | =item 2.01beta (10 April 1996) |
155 | |
156 | Minor bugfix (single digit numbers were always getting quoted). |
157 | |
158 | |
159 | =item 2.00beta (9 April 1996) |
160 | |
161 | C<Dumpxs> is now the exact XSUB equivalent of C<Dump>. The XS version |
162 | is 4-5 times faster. |
163 | |
164 | C<require 5.002>. |
165 | |
166 | MLDBM example removed (as its own module, it has a separate CPAN |
167 | reality now). |
168 | |
169 | Fixed bugs in handling keys with wierd characters. Perl can be |
170 | tripped up in its implicit quoting of the word before '=>'. The |
171 | fix: C<Data::Dumper::Purity>, when set, always triggers quotes |
172 | around hash keys. |
173 | |
174 | Andreas Koenig <k@anna.in-berlin.de> pointed out that handling octals |
175 | is busted. His patch added. |
176 | |
177 | Dead code removed, other minor documentation fixes. |
178 | |
179 | |
180 | =item 1.23 (3 Dec 1995) |
181 | |
182 | MLDBM example added. |
183 | |
184 | Several folks pointed out that quoting of ticks and backslashes |
185 | in strings is missing. Added. |
186 | |
7e6e257f |
187 | Ian Phillipps <ian@pipex.net> pointed out that numerics may lose |
823edd99 |
188 | precision without quotes. Fixed. |
189 | |
190 | |
191 | =item 1.21 (20 Nov 1995) |
192 | |
193 | Last stable version I can remember. |
