Convert the tracking system to a 256-way tree.

[p5sagit/Devel-Size.git] / CHANGES

Revision history for Perl extension Devel::Size.

0.72_50 2011-04-14 nicholas
 * Exception handling is totally MSVC specific, so only use it there
   - this means that we don't need to use a C++ compiler anywhere
 * Rework bit-vector tracking mechanism to use a 256-way tree. This avoids
   making assumptions about 64-bit platforms' memory layouts, and eliminates
   the fatal error introduced in 0.72 when the assumption was violated.
 * Resolve CPAN #49437 (Devel::Size adds magic in Perl 5.10)

0.72 2008-10-14 BrowserUk 70 tests
 * Added bit-vector pointer tracking mechanism.
   - new fatal error (64-bit platforms only)
 * Added exception handling
    - 4 new warnings (disabled by default)
 * Updated POD to reflect above
 * Added basic.t test 13 
 * replaced Module::Install with hand crafted EU::MM Makefile.pl
   (With many thanks to Sisyphus)
   because we couldn't work out how to add C++ options to allow 
   exception handling.

0.71 2008-08-24 Tels 69 tests
  * adapt patch from Reini Urban to fix failing RV under 5.10 and 5.11. AV
    and HV were pushed directly onto the pending_array, and not the RV,
    which caused #33530. So he rewrote the logic to deref the RV inside
    the array traversal. Applied this with one small omission, which
    caused test faiures.
  * Fixed 5.11 RV/IV logic. (Thanx Reini Urban!)
  * Removed one duplicate total_size arrayref test. (Thanx Reini Urban!)
  * changed //printf to dbg_printf() (Thanx Reini again!)

0.70 2008-08-23 Tels 69 tests
  * fix SEGFAULTS under v5.10 (Thanx Reini Urban!)
  * fix compilation under blead (Thanx Reini Urban!)
  * require Perl 5.006 (to stop CPANTESTERS sending bogus reports
    about failed compiling on ancient Perls)
  * update the bundles Module::Install to v0.77

0.69 2007-08-11 Tels 69 tests
  * fix compilation under Perl v5.9.5 and v5.10 (Thanx Steve Peters!)
  * clarify the license by specifying Perl v5.8.8's license
  * small doc fixes, add a README file

0.68 2007-06-12 Tels 69 tests
  * remove a bit of duplicate code in op_size, the second instance
    was a no-op anyway
  * fix the failing tests by rewriting the test logic to be sane
  * the count of array slots was off by one

0.67 2007-03-15 Tels 20 tests
  * rip out Build.PL since it doesn't actually work
  * fix bug #1653: All SVPV subtype may contain an RV instead of a PV
    (Thanx a lot Jan, and sorry for the truly horrible long delay!)
  * fix bug #24846: Does not correctly recurse into references in PVNV
    (Thanx STEVIEO)
  * add t/recurse.t that tests the two bugfixes in combination

0.66 2007-03-02 Tels 15 tests
  * fix the failing test (the code was right, but the test wrong)

0.65 2007-02-24 Tels 15 tests
  * fix the test failings under 64 bit (bugs #21037, #18596, #21404)
  * fix wrong size for strings (bug #17586)
  * reverse Changelog (bug #16636)
  * Size.xs: remove unused variable "count"
  * Size.xs: fix warnings about missing ()
  * Size.xs: fix size of array refs when AvALLOC == 0
  * Modernize package:
    + maintained by me, signed with my key
    + bundle Module::Install and use it
    + add POD tests
    + rewrite tests to use Test::More; add more tests

        - Patch to make Devel::Size compile on bleadperl (Courtesy of
      Nick Clark)
    - Fix up the PVIV string size calcs (Courtesy of Andrew Shirrayev)

0.63  Thu Jun 30 14:29:43 2005
        - Turns out that OP_TRANS is a basic op, not a loop op. This
      is a bug in versions of perl 5.8.x before 5.8.7. Work around
      it.

0.62  Tue Jun 28 11:59:00 2005
        - Took out // comments
    - Added in copyright notice
    - Some small amount of regex parsing
    - Suppress multiple copies of each warning on each call

0.61  Mon Jun 27 16:19:00 2005
        - Added more checks for formats
    - Got CVs sizing right

0.59  Sat Nov 27 16:42:42 2004
        - Applied documentation and sane warning patch from Nigel Sandever
        - Taught Devel::Size how to size up IO and globs properly

0.58  Fri Jul 18 11:42:32 2003
        - Fix for problems triggered by perl 5.8.0 and up, more tests, and
      removal of an "our" for better backwards compatibility. (Courtesy
      of Marcus Holland-Moritz <mhx-perl@gmx.net>)

0.57  Thu Mar 20 13:21:14 2003
        - setting $Devel::Size::warn to 0 disables not complete warnings

0.56  Mon Feb 24 12:10:13 2003
        - Chopped out some C++ comments. D'oh! Version incremented for CPAN

0.55  Sat Feb 22 17:21:00 2003
        - Fixed a bad size calculation (we were overestimating by one byte)
    - Updated the docs to show some of the places that there might be 'dark'
      memory that Devel::Size can't see.
    - Added in tests from Ken Williams

0.54  Sat Oct 12 14:11:00 2002
    - Applied a patch to get it working on 5.8.0 under Tru64

0.53  Thu Oct 10 12:30:00 2002
        - Finally started updating Changes file
    - Applied doc patch from Ann Barcomb
    - Got globs sizing right
