3 HISTORY - public release history for Data::Dumper
9 =item 2.10 (31 Oct 1998)
11 Bugfixes for dumping related undef values, globs, and better double
12 quoting: three patches suggested by Gisle Aas <gisle@aas.no>.
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>.
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
25 Various additions to the testsuite.
27 =item 2.09 (9 July 1998)
29 Implement $Data::Dumper::Bless, suggested by Mark Daku <daku@nortel.ca>.
31 =item 2.081 (15 January 1998)
33 Minor release to fix Makefile.PL not accepting MakeMaker args.
35 =item 2.08 (7 December 1997)
37 Glob dumps don't output superflous 'undef' anymore.
39 Fixes from Gisle Aas <gisle@aas.no> to make Dumper() work with
40 overloaded strings in recent perls, and his new testsuite.
44 A separate flag to always quote hash keys (on by default).
46 Recreating known CODE refs is now better supported.
48 Changed flawed constant SCALAR bless workaround.
50 =item 2.07 (7 December 1996)
52 Dumpxs output is now exactly the same as Dump. It still doesn't
53 honor C<Useqq> though.
55 Regression tests test for identical output and C<eval>-ability.
57 Bug in *GLOB{THING} output fixed.
59 Other small enhancements.
61 =item 2.06 (2 December 1996)
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().)
67 =item 2.05 (2 December 1996)
69 Fixed the type mismatch that was causing Dumpxs test to fail
72 GLOB elements are dumped now when C<Purity> is set (using the
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.
81 The corresponding C<Toaster> option, if set, specifies
82 the method call that will revive the frozen object.
84 The C<Deepcopy> flag has been added to do just that.
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.
90 Objects that C<overload> the '""' operator are now handled
91 properly by the C<Dump> method.
93 Significant additions to the testsuite.
97 =item 2.04beta (28 August 1996)
99 Made dump of glob names respect C<Useqq> setting.
101 [@$%] are now escaped now when in double quotes.
103 =item 2.03beta (26 August 1996)
105 Fixed Dumpxs. It was appending trailing nulls to globnames.
106 (reported by Randal Schwartz <merlyn@teleport.com>).
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>).
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.
116 The C<Useqq> flag is supported (but not by the XSUB version
119 Embedded nulls in keys are now handled properly by Dumpxs.
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).
125 All the dump methods now return a list of strings in a list
129 =item 2.02beta (13 April 1996)
131 Non portable sprintf usage in XS code fixed (thanks to
132 Ulrich Pfeifer <pfeifer@charly.informatik.uni-dortmund.de>).
135 =item 2.01beta (10 April 1996)
137 Minor bugfix (single digit numbers were always getting quoted).
140 =item 2.00beta (9 April 1996)
142 C<Dumpxs> is now the exact XSUB equivalent of C<Dump>. The XS version
147 MLDBM example removed (as its own module, it has a separate CPAN
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
155 Andreas Koenig <k@anna.in-berlin.de> pointed out that handling octals
156 is busted. His patch added.
158 Dead code removed, other minor documentation fixes.
161 =item 1.23 (3 Dec 1995)
165 Several folks pointed out that quoting of ticks and backslashes
166 in strings is missing. Added.
168 Ian Phillips <ian@pipex.net> pointed out that numerics may lose
169 precision without quotes. Fixed.
172 =item 1.21 (20 Nov 1995)
174 Last stable version I can remember.
