| 9 | =item 2.121 (Aug 24 2003)
|
|---|
| 10 |
|
|---|
| 11 | Backport to 5.6.1 by Ilya Martynov <[email protected]>.
|
|---|
| 12 |
|
|---|
| 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 <[email protected]>.
|
|---|
| 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.
|
|---|
| 27 |
|
|---|
| 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 <[email protected]>.
|
|---|
| 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 <[email protected]>.
|
|---|
| 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.
|
|---|
| 45 |
|
|---|
| 46 | =item 2.09 (9 July 1998)
|
|---|
| 47 |
|
|---|
| 48 | Implement $Data::Dumper::Bless, suggested by Mark Daku <[email protected]>.
|
|---|
| 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 <[email protected]> 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 | <[email protected]> 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 <[email protected]>).
|
|---|
| 126 |
|
|---|
| 127 | Calling the C<Indent()> method on a dumper object now correctly
|
|---|
| 128 | resets the internal separator (reported by Curt Tilmes
|
|---|
| 129 | <[email protected]>).
|
|---|
| 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 <[email protected]>).
|
|---|
| 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 <[email protected]> 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 |
|
|---|
| 187 | Ian Phillipps <[email protected]> pointed out that numerics may lose
|
|---|
| 188 | precision without quotes. Fixed.
|

|
|---|
| 191 | =item 1.21 (20 Nov 1995)
