+Revision history for Perl extension Devel::Memory.
- * Spelling fix to docs from gregor herrmann [CPAN #78766]
- * Fix measurement of struct svop [Tim]

- [no changes]
+ * Created new Devel::Memory extension using a modified version of
+ Devel::Size's perl memory data crawler, extended to support
+ callbacks, a 'data path name' concept, data streaming,
+ data processing and visualization.
-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.
-
-0.77 2011-05-16 nicholas
- [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

-
-0.63 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

- - Got CVs sizing right
-
-0.59 Sat Nov 27 16:42:42 2004
- - Applied documentation and sane warning patch from Nigel Sandever

- of Marcus Holland-Moritz <mhx-perl@gmx.net>)
-
-0.57 Thu Mar 20 13:21:14 2003

-
-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
+ * The Devel::Memory core was based on 0.77. The generic changes
+ will be fed back to Devel::Size so it will remain the
+ canonical source of knowledge of how to crawl perl internals.
+ Once Devel::Size has the changes then Devel::Memory will use
+ it as the core, but compiled with options to enable the extra
+ features. That way Devel::Size won't have any performance penalty.
+ * This is very much experimental 'alpha' software. You're milage will
+ vary and anything may change between releases.
