Revision history for Perl extension Devel::Size.
+0.72_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().
+
+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
