1 Revision history for Perl extension Devel::Size.
3 0.79 2013-05-12 nicholas
6 0.78_52 2013-05-10 nicholas
7 * Fix the bug in the previous fix. Oops :-)
9 0.78_51 2013-05-10 nicholas
10 * v5.17.1 and later handle CopSTASH differently under ithreads
12 0.78_50 2013-05-10 nicholas
13 * Alternative test for CvOUTSIDE, and one for CvPADLIST
14 * v5.17 changes the type of PADLIST [CPAN #83904]
15 * stubbed subs no longer have CvOUTSIDE set [CPAN #77913]
16 * Fix for v5.17.2's OP slab allocator [CPAN #83903]
17 * Spelling fix to docs from gregor herrmann [CPAN #78766]
19 0.78 2012-07-26 nicholas
22 0.77_51 2012-07-17 nicholas
23 * Fix for MSVC builds from bulk 88 [CPAN #77589]
25 0.77_50 2012-02-10 nicholas
26 * t/globs.t was failing on 5.15.6 and later due to side effects of a change
27 to strict.pm [CPAN #73998]
28 * skip tests in t/magic.t that use formline on 5.8.1 and 5.8.2, as those
29 versions have a buggy formline that can trigger an assertion failure.
31 0.77 2011-05-16 nicholas
34 0.76_50 2011-05-12 nicholas
35 * Split out HEK size calculation into hek_size(). Add the shared HE overhead.
36 * Handle shared hash key scalars correctly.
37 * GvNAME() is shared from 5.10 onwards.
38 * Count HvNAME(), the HV "aux" struct, the mro_meta struct, and ENAMEs.
40 0.76 2011-05-11 nicholas
41 * Just fix the version number in the line below.
43 0.75_52 2011-05-09 nicholas
44 * Use a table for SV body sizes. These incorporate the space saving post 5.8.x
45 * Correctly handle SvOOK scalars. 5.12 and later don't use SvIVX().
46 * Magic vtables aren't freed when magic is freed, so don't count them.
47 (They are static structures. Anything that assumes otherwise is buggy.)
48 * Reinstate 5.6.x "support". (i.e. it compiles and passes tests.)
49 * Reinstate 5.005_xx "support". (i.e. it compiles and passes tests.)
51 0.75_51 2011-05-05 nicholas
52 * Only use a static array of vtables on gcc.
54 0.75_50 2011-05-04 nicholas
55 * The core's magic vtables are global constants, so aren't part of the size.
56 * Follow mg_obj and mg_ptr.
58 0.75 2011-05-04 nicholas
61 0.74_53 2011-05-01 nicholas
62 * Fix typo error in bit-vector tracking mechanism. On 64 bit platforms which
63 allocate on 8 byte alignment (rather than 16), a low pointer bit could get
64 lost, resulting in new pointers being considered already "seen".
65 "Found" by BinGOs' smoker, fixed on spectre.mongueurs.net. Thanks.
67 0.74_52 2011-04-23 nicholas
68 * Fix potential SEGVs for OP_AELEMFAST on a lexical (eg $foo[3])
69 * Fix likely SEGVs for PVOPs (missing break)
70 * Fix potential SEGVs for PVBMs on 5.10 and later
71 * Move hash and array traversal from total_size() to sv_size()
72 - this allows total_size() and size() to be XS ALIASes.
74 0.74_51 2011-04-22 nicholas
75 * Don't count PL_sv_{undef,no,yes} in the size returned
76 * total_size() was double-counting entries in typeglobs
77 * sv_size() was double-counting the PVGV size if GvEGV() looped back
78 * fix classic off-by-one error - the answer is strlen() + 1, not just strlen()
80 0.74_50 2011-04-19 nicholas
81 * Ensure that size() doesn't add the referent's size for non SVt_RV references
83 0.74 2011-04-19 nicholas
84 * Correct the Makefile.PL - LICENSE was added to ExtUtils::MakeMaker in 6.31
86 0.73_51 2011-04-17 nicholas
87 * Refactor the C code to accumulate the size inside the tracking structure
88 - this means that the C *_size() functions now return void
89 - The XS functions size() and total_size() now return UV, not IV
91 0.73_50 2011-04-17 nicholas
92 * Avoid using assert() on ithreaded 5.8.8 and earlier, as it needs my_perl
93 * Fix the test added in 0.73, as it tripped over a combination of bugs
95 0.73 2011-04-16 nicholas
96 * Revert a bad assertion introduced in 0.72_50, which was logically wrong.
97 - and a test to demonstrate one case that would trigger it
99 0.72_52 2011-04-15 nicholas
100 * Add a test for the non-exceptional warnings.
102 0.72_51 2011-04-15 nicholas
103 * Add PERL_NO_GET_CONTEXT to improve performance under multiplicity
105 0.72_50 2011-04-14 nicholas
106 * Exception handling is totally MSVC specific, so only use it there
107 - this means that we don't need to use a C++ compiler anywhere
108 * Rework bit-vector tracking mechanism to use a 256-way tree. This avoids
109 making assumptions about 64-bit platforms' memory layouts, and eliminates
110 the fatal error introduced in 0.72 when the assumption was violated.
111 * Convert to XSLoader
112 * Resolve CPAN #49437 (Devel::Size adds magic in Perl 5.10)
113 * Resolve CPAN #58484 and #58485 (related to CVs that are XSUBs)
115 0.72 2008-10-14 BrowserUk 70 tests
116 * Added bit-vector pointer tracking mechanism.
117 - new fatal error (64-bit platforms only)
118 * Added exception handling
119 - 4 new warnings (disabled by default)
120 * Updated POD to reflect above
121 * Added basic.t test 13
122 * replaced Module::Install with hand crafted EU::MM Makefile.pl
123 (With many thanks to Sisyphus)
124 because we couldn't work out how to add C++ options to allow
127 0.71 2008-08-24 Tels 69 tests
128 * adapt patch from Reini Urban to fix failing RV under 5.10 and 5.11. AV
129 and HV were pushed directly onto the pending_array, and not the RV,
130 which caused #33530. So he rewrote the logic to deref the RV inside
131 the array traversal. Applied this with one small omission, which
133 * Fixed 5.11 RV/IV logic. (Thanx Reini Urban!)
134 * Removed one duplicate total_size arrayref test. (Thanx Reini Urban!)
135 * changed //printf to dbg_printf() (Thanx Reini again!)
137 0.70 2008-08-23 Tels 69 tests
138 * fix SEGFAULTS under v5.10 (Thanx Reini Urban!)
139 * fix compilation under blead (Thanx Reini Urban!)
140 * require Perl 5.006 (to stop CPANTESTERS sending bogus reports
141 about failed compiling on ancient Perls)
142 * update the bundles Module::Install to v0.77
144 0.69 2007-08-11 Tels 69 tests
145 * fix compilation under Perl v5.9.5 and v5.10 (Thanx Steve Peters!)
146 * clarify the license by specifying Perl v5.8.8's license
147 * small doc fixes, add a README file
149 0.68 2007-06-12 Tels 69 tests
150 * remove a bit of duplicate code in op_size, the second instance
152 * fix the failing tests by rewriting the test logic to be sane
153 * the count of array slots was off by one
155 0.67 2007-03-15 Tels 20 tests
156 * rip out Build.PL since it doesn't actually work
157 * fix bug #1653: All SVPV subtype may contain an RV instead of a PV
158 (Thanx a lot Jan, and sorry for the truly horrible long delay!)
159 * fix bug #24846: Does not correctly recurse into references in PVNV
161 * add t/recurse.t that tests the two bugfixes in combination
163 0.66 2007-03-02 Tels 15 tests
164 * fix the failing test (the code was right, but the test wrong)
166 0.65 2007-02-24 Tels 15 tests
167 * fix the test failings under 64 bit (bugs #21037, #18596, #21404)
168 * fix wrong size for strings (bug #17586)
169 * reverse Changelog (bug #16636)
170 * Size.xs: remove unused variable "count"
171 * Size.xs: fix warnings about missing ()
172 * Size.xs: fix size of array refs when AvALLOC == 0
174 + maintained by me, signed with my key
175 + bundle Module::Install and use it
177 + rewrite tests to use Test::More; add more tests

203 0.58 Fri Jul 18 11:42:32 2003
204 - Fix for problems triggered by perl 5.8.0 and up, more tests, and
205 removal of an "our" for better backwards compatibility. (Courtesy
206 of Marcus Holland-Moritz <mhx-perl@gmx.net>)
208 0.57 Thu Mar 20 13:21:14 2003

214 0.55 Sat Feb 22 17:21:00 2003
215 - Fixed a bad size calculation (we were overestimating by one byte)
216 - Updated the docs to show some of the places that there might be 'dark'
217 memory that Devel::Size can't see.
218 - Added in tests from Ken Williams
220 0.54 Sat Oct 12 14:11:00 2002
