Revision history for Perl extension Devel::Size.
0.78 2011-07-26 nicholas
[no changes]
0.77_51 2012-07-17 nicholas
* Fix for MSVC builds from bulk 88 [CPAN #77589]
0.77_50 2012-02-10 nicholas
* t/globs.t was failing on 5.15.6 and later due to side effects of a change
to strict.pm [CPAN #73998]
* skip tests in t/magic.t that use formline on 5.8.1 and 5.8.2, as those
versions have a buggy formline that can trigger an assertion failure.

[no changes]
0.76_50 2011-05-12 nicholas
* Split out HEK size calculation into hek_size(). Add the shared HE overhead.
* Handle shared hash key scalars correctly.
* GvNAME() is shared from 5.10 onwards.
* Count HvNAME(), the HV "aux" struct, the mro_meta struct, and ENAMEs.
0.76 2011-05-11 nicholas
* Just fix the version number in the line below.
0.75_52 2011-05-09 nicholas
* Use a table for SV body sizes. These incorporate the space saving post 5.8.x
* Correctly handle SvOOK scalars. 5.12 and later don't use SvIVX().
* Magic vtables aren't freed when magic is freed, so don't count them.
(They are static structures. Anything that assumes otherwise is buggy.)
* Reinstate 5.6.x "support". (i.e. it compiles and passes tests.)
* Reinstate 5.005_xx "support". (i.e. it compiles and passes tests.)
0.75_51 2011-05-05 nicholas
* Only use a static array of vtables on gcc.
0.75_50 2011-05-04 nicholas
* The core's magic vtables are global constants, so aren't part of the size.
* Follow mg_obj and mg_ptr.
0.75 2011-05-04 nicholas
[no changes]
0.74_53 2011-05-01 nicholas
* Fix typo error in bit-vector tracking mechanism. On 64 bit platforms which
allocate on 8 byte alignment (rather than 16), a low pointer bit could get
lost, resulting in new pointers being considered already "seen".
"Found" by BinGOs' smoker, fixed on spectre.mongueurs.net. Thanks.
0.74_52 2011-04-23 nicholas
* Fix potential SEGVs for OP_AELEMFAST on a lexical (eg $foo[3])
* Fix likely SEGVs for PVOPs (missing break)
* Fix potential SEGVs for PVBMs on 5.10 and later
* Move hash and array traversal from total_size() to sv_size()
- this allows total_size() and size() to be XS ALIASes.
0.74_51 2011-04-22 nicholas
* Don't count PL_sv_{undef,no,yes} in the size returned
* total_size() was double-counting entries in typeglobs
* sv_size() was double-counting the PVGV size if GvEGV() looped back
* fix classic off-by-one error - the answer is strlen() + 1, not just strlen()
0.74_50 2011-04-19 nicholas
* Ensure that size() doesn't add the referent's size for non SVt_RV references
0.74 2011-04-19 nicholas
* Correct the Makefile.PL - LICENSE was added to ExtUtils::MakeMaker in 6.31
0.73_51 2011-04-17 nicholas
* Refactor the C code to accumulate the size inside the tracking structure
- this means that the C *_size() functions now return void
- The XS functions size() and total_size() now return UV, not IV
0.73_50 2011-04-17 nicholas
* Avoid using assert() on ithreaded 5.8.8 and earlier, as it needs my_perl
* Fix the test added in 0.73, as it tripped over a combination of bugs
0.73 2011-04-16 nicholas
* Revert a bad assertion introduced in 0.72_50, which was logically wrong.
- and a test to demonstrate one case that would trigger it
0.72_52 2011-04-15 nicholas
* Add a test for the non-exceptional warnings.
0.72_51 2011-04-15 nicholas
* Add PERL_NO_GET_CONTEXT to improve performance under multiplicity
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.
* Convert to XSLoader
* Resolve CPAN #49437 (Devel::Size adds magic in Perl 5.10)
* Resolve CPAN #58484 and #58485 (related to CVs that are XSUBs)
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
0.64 Mon Dec 19 18:46:00 2005
- 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
