HISTORY - public release history for Data::Dumper
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
=over 8
|
|
|
|
=item 2.09 (9 July 1998)
|
|
|
|
Implement $Data::Dumper::Bless, suggested by Mark Daku <daku@nortel.ca>.
|
|
|
|
=item 2.081 (15 January 1998)
|
|
|
|
Minor release to fix Makefile.PL not accepting MakeMaker args.
|
|
|
|
=item 2.08 (7 December 1997)
|
|
|
|
Glob dumps don't output superflous 'undef' anymore.
|
|
|
|
Fixes from Gisle Aas <gisle@aas.no> to make Dumper() work with
|
|
overloaded strings in recent perls, and his new testsuite.
|
|
|
|
require 5.004.
|
|
|
|
A separate flag to always quote hash keys (on by default).
|
|
|
|
Recreating known CODE refs is now better supported.
|
|
|
|
Changed flawed constant SCALAR bless workaround.
|
|
|
|
=item 2.07 (7 December 1996)
|
|
|
|
Dumpxs output is now exactly the same as Dump. It still doesn't
|
|
honor C<Useqq> though.
|
|
|
|
Regression tests test for identical output and C<eval>-ability.
|
|
|
|
Bug in *GLOB{THING} output fixed.
|
|
|
|
Other small enhancements.
|
|
|
|
=item 2.06 (2 December 1996)
|
|
|
|
Bugfix that was serious enough for new release--the bug cripples
|
|
MLDBM. Problem was "Attempt to modify readonly value..." failures
|
|
that stemmed for a misguided SvPV_force() instead of a SvPV().)
|
|
|
|
=item 2.05 (2 December 1996)
|
|
|
|
Fixed the type mismatch that was causing Dumpxs test to fail
|
|
on 64-bit platforms.
|
|
|
|
GLOB elements are dumped now when C<Purity> is set (using the
|
|
*GLOB{THING} syntax).
|
|
|
|
The C<Freezer> option can be set to a method name to call
|
|
before probing objects for dumping. Some applications: objects with
|
|
external data, can re-bless themselves into a transitional package;
|
|
Objects the maintain ephemeral state (like open files) can put
|
|
additional information in the object to facilitate persistence.
|
|
|
|
The corresponding C<Toaster> option, if set, specifies
|
|
the method call that will revive the frozen object.
|
|
|
|
The C<Deepcopy> flag has been added to do just that.
|
|
|
|
Dumper does more aggressive cataloging of SCALARs encountered
|
|
within ARRAY/HASH structures. Thanks to Norman Gaywood
|
|
<norm@godel.une.edu.au> for reporting the problem.
|
|
|
|
Objects that C<overload> the '""' operator are now handled
|
|
properly by the C<Dump> method.
|
|
|
|
Significant additions to the testsuite.
|
|
|
|
More documentation.
|
|
|
|
=item 2.04beta (28 August 1996)
|
|
|
|
Made dump of glob names respect C<Useqq> setting.
|
|
|
|
[@$%] are now escaped now when in double quotes.
|
|
|
|
=item 2.03beta (26 August 1996)
|
|
|
|
Fixed Dumpxs. It was appending trailing nulls to globnames.
|
|
(reported by Randal Schwartz <merlyn@teleport.com>).
|
|
|
|
Calling the C<Indent()> method on a dumper object now correctly
|
|
resets the internal separator (reported by Curt Tilmes
|
|
<curt@ltpmail.gsfc.nasa.gov>).
|
|
|
|
New C<Terse> option to suppress the 'C<VARI<n> = >' prefix
|
|
introduced. If the option is set, they are output only when
|
|
absolutely essential.
|
|
|
|
The C<Useqq> flag is supported (but not by the XSUB version
|
|
yet).
|
|
|
|
Embedded nulls in keys are now handled properly by Dumpxs.
|
|
|
|
Dumper.xs now use various integer types in perl.h (should
|
|
make it compile without noises on 64 bit platforms, although
|
|
I haven't been able to test this).
|
|
|
|
All the dump methods now return a list of strings in a list
|
|
context.
|
|
|
|
|
|
=item 2.02beta (13 April 1996)
|
|
|
|
Non portable sprintf usage in XS code fixed (thanks to
|
|
Ulrich Pfeifer <pfeifer@charly.informatik.uni-dortmund.de>).
|
|
|
|
|
|
=item 2.01beta (10 April 1996)
|
|
|
|
Minor bugfix (single digit numbers were always getting quoted).
|
|
|
|
|
|
=item 2.00beta (9 April 1996)
|
|
|
|
C<Dumpxs> is now the exact XSUB equivalent of C<Dump>. The XS version
|
|
is 4-5 times faster.
|
|
|
|
C<require 5.002>.
|
|
|
|
MLDBM example removed (as its own module, it has a separate CPAN
|
|
reality now).
|
|
|
|
Fixed bugs in handling keys with wierd characters. Perl can be
|
|
tripped up in its implicit quoting of the word before '=>'. The
|
|
fix: C<Data::Dumper::Purity>, when set, always triggers quotes
|
|
around hash keys.
|
|
|
|
Andreas Koenig <k@anna.in-berlin.de> pointed out that handling octals
|
|
is busted. His patch added.
|
|
|
|
Dead code removed, other minor documentation fixes.
|
|
|
|
|
|
=item 1.23 (3 Dec 1995)
|
|
|
|
MLDBM example added.
|
|
|
|
Several folks pointed out that quoting of ticks and backslashes
|
|
in strings is missing. Added.
|
|
|
|
Ian Phillips <ian@pipex.net> pointed out that numerics may lose
|
|
precision without quotes. Fixed.
|
|
|
|
|
|
=item 1.21 (20 Nov 1995)
|
|
|
|
Last stable version I can remember.
