Revision history for Perl extension Devel::Size. 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 ) 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 0.01 Mon Oct 7 01:05:32 2002 - original version; created by h2xs 1.2 with options -A -n Devel::Size
