9 | =item 2.10 (31 Oct 1998) |
10 | |
11 | Bugfixes for dumping related undef values, globs, and better double |
12 | quoting: three patches suggested by Gisle Aas <gisle@aas.no>. |
13 | |
14 | Escaping of single quotes in the XS version could get tripped up |
15 | by the presence of nulls in the string. Fix suggested by |
16 | Slaven Rezic <eserte@cs.tu-berlin.de>. |
17 | |
18 | Rather large scale reworking of the logic in how seen values |
19 | are stashed. Anonymous scalars that may be encountered while |
20 | traversing the structure are properly tracked, in case they become |
21 | used in data dumped in a later pass. There used to be a problem |
22 | with the previous logic that prevented such structures from being |
23 | dumped correctly. |
24 | |
25 | Various additions to the testsuite. |

27 | =item 2.09 (9 July 1998) |
28 | |
29 | Implement $Data::Dumper::Bless, suggested by Mark Daku <daku@nortel.ca>. |
30 | |
31 | =item 2.081 (15 January 1998) |
32 | |
33 | Minor release to fix Makefile.PL not accepting MakeMaker args. |
34 | |
35 | =item 2.08 (7 December 1997) |
36 | |
37 | Glob dumps don't output superflous 'undef' anymore. |
38 | |
39 | Fixes from Gisle Aas <gisle@aas.no> to make Dumper() work with |
40 | overloaded strings in recent perls, and his new testsuite. |
41 | |
42 | require 5.004. |
43 | |
44 | A separate flag to always quote hash keys (on by default). |
45 | |
46 | Recreating known CODE refs is now better supported. |
47 | |
48 | Changed flawed constant SCALAR bless workaround. |
49 | |
50 | =item 2.07 (7 December 1996) |
51 | |
52 | Dumpxs output is now exactly the same as Dump. It still doesn't |
53 | honor C<Useqq> though. |
54 | |
55 | Regression tests test for identical output and C<eval>-ability. |
56 | |
57 | Bug in *GLOB{THING} output fixed. |
58 | |
59 | Other small enhancements. |
60 | |
61 | =item 2.06 (2 December 1996) |
62 | |
63 | Bugfix that was serious enough for new release--the bug cripples |
64 | MLDBM. Problem was "Attempt to modify readonly value..." failures |
65 | that stemmed for a misguided SvPV_force() instead of a SvPV().) |
66 | |
67 | =item 2.05 (2 December 1996) |
68 | |
69 | Fixed the type mismatch that was causing Dumpxs test to fail |
70 | on 64-bit platforms. |
71 | |
72 | GLOB elements are dumped now when C<Purity> is set (using the |
73 | *GLOB{THING} syntax). |
74 | |
75 | The C<Freezer> option can be set to a method name to call |
76 | before probing objects for dumping. Some applications: objects with |
77 | external data, can re-bless themselves into a transitional package; |
78 | Objects the maintain ephemeral state (like open files) can put |
79 | additional information in the object to facilitate persistence. |
80 | |
81 | The corresponding C<Toaster> option, if set, specifies |
82 | the method call that will revive the frozen object. |
83 | |
84 | The C<Deepcopy> flag has been added to do just that. |
85 | |
86 | Dumper does more aggressive cataloging of SCALARs encountered |
87 | within ARRAY/HASH structures. Thanks to Norman Gaywood |
88 | <norm@godel.une.edu.au> for reporting the problem. |
89 | |
90 | Objects that C<overload> the '""' operator are now handled |
91 | properly by the C<Dump> method. |
92 | |
93 | Significant additions to the testsuite. |
94 | |
95 | More documentation. |
96 | |
97 | =item 2.04beta (28 August 1996) |
98 | |
99 | Made dump of glob names respect C<Useqq> setting. |
100 | |
101 | [@$%] are now escaped now when in double quotes. |
102 | |
103 | =item 2.03beta (26 August 1996) |
104 | |
105 | Fixed Dumpxs. It was appending trailing nulls to globnames. |
106 | (reported by Randal Schwartz <merlyn@teleport.com>). |
107 | |
108 | Calling the C<Indent()> method on a dumper object now correctly |
109 | resets the internal separator (reported by Curt Tilmes |
110 | <curt@ltpmail.gsfc.nasa.gov>). |
111 | |
112 | New C<Terse> option to suppress the 'C<VARI<n> = >' prefix |
113 | introduced. If the option is set, they are output only when |
114 | absolutely essential. |
115 | |
116 | The C<Useqq> flag is supported (but not by the XSUB version |
117 | yet). |
118 | |
119 | Embedded nulls in keys are now handled properly by Dumpxs. |
120 | |
121 | Dumper.xs now use various integer types in perl.h (should |
122 | make it compile without noises on 64 bit platforms, although |
123 | I haven't been able to test this). |
124 | |
125 | All the dump methods now return a list of strings in a list |
126 | context. |
127 | |
128 | |
129 | =item 2.02beta (13 April 1996) |
130 | |
131 | Non portable sprintf usage in XS code fixed (thanks to |
132 | Ulrich Pfeifer <pfeifer@charly.informatik.uni-dortmund.de>). |
133 | |
134 | |
135 | =item 2.01beta (10 April 1996) |
136 | |
137 | Minor bugfix (single digit numbers were always getting quoted). |
138 | |
139 | |
140 | =item 2.00beta (9 April 1996) |
141 | |
142 | C<Dumpxs> is now the exact XSUB equivalent of C<Dump>. The XS version |
143 | is 4-5 times faster. |
144 | |
145 | C<require 5.002>. |
146 | |
147 | MLDBM example removed (as its own module, it has a separate CPAN |
148 | reality now). |
149 | |
150 | Fixed bugs in handling keys with wierd characters. Perl can be |
151 | tripped up in its implicit quoting of the word before '=>'. The |
152 | fix: C<Data::Dumper::Purity>, when set, always triggers quotes |
153 | around hash keys. |
154 | |
155 | Andreas Koenig <k@anna.in-berlin.de> pointed out that handling octals |
156 | is busted. His patch added. |
157 | |
158 | Dead code removed, other minor documentation fixes. |
159 | |
160 | |
161 | =item 1.23 (3 Dec 1995) |
162 | |
163 | MLDBM example added. |
164 | |
165 | Several folks pointed out that quoting of ticks and backslashes |
166 | in strings is missing. Added. |
167 | |
168 | Ian Phillips <ian@pipex.net> pointed out that numerics may lose |
169 | precision without quotes. Fixed. |
170 | |
171 | |
172 | =item 1.21 (20 Nov 1995) |
173 | |
174 | Last stable version I can remember. |
