1 Revision history for Perl extension Devel::Size.
3 0.79_52 2015-03-20 nicholas
4 two patches from Zefram:
5 * handle the new METHOP. [CPAN #101071]
6 * handle the multideref op, and to a limited extent the UNOP_AUX op class in
7 general. [CPAN #102911]
9 0.79_51 2015-02-28 nicholas
10 * as of 5.20.0, s/// is no longer a reliable test for OOK [CPAN #95493]
12 0.79_50 2015-02-28 nicholas
14 * wrong test for magicalness [CPAN #88180]
15 * reading tied scalar shrinks it [CPAN #88182]
17 0.79 2013-05-12 nicholas
20 0.78_52 2013-05-10 nicholas
21 * Fix the bug in the previous fix. Oops :-)
23 0.78_51 2013-05-10 nicholas
24 * v5.17.1 and later handle CopSTASH differently under ithreads
26 0.78_50 2013-05-10 nicholas
27 * Alternative test for CvOUTSIDE, and one for CvPADLIST
28 * v5.17 changes the type of PADLIST [CPAN #83904]
29 * stubbed subs no longer have CvOUTSIDE set [CPAN #77913]
30 * Fix for v5.17.2's OP slab allocator [CPAN #83903]
31 * Spelling fix to docs from gregor herrmann [CPAN #78766]
33 0.78 2012-07-26 nicholas
36 0.77_51 2012-07-17 nicholas
37 * Fix for MSVC builds from bulk 88 [CPAN #77589]
39 0.77_50 2012-02-10 nicholas
40 * t/globs.t was failing on 5.15.6 and later due to side effects of a change
41 to strict.pm [CPAN #73998]
42 * skip tests in t/magic.t that use formline on 5.8.1 and 5.8.2, as those
43 versions have a buggy formline that can trigger an assertion failure.
45 0.77 2011-05-16 nicholas
48 0.76_50 2011-05-12 nicholas
49 * Split out HEK size calculation into hek_size(). Add the shared HE overhead.
50 * Handle shared hash key scalars correctly.
51 * GvNAME() is shared from 5.10 onwards.
52 * Count HvNAME(), the HV "aux" struct, the mro_meta struct, and ENAMEs.
54 0.76 2011-05-11 nicholas
55 * Just fix the version number in the line below.
57 0.75_52 2011-05-09 nicholas
58 * Use a table for SV body sizes. These incorporate the space saving post 5.8.x
59 * Correctly handle SvOOK scalars. 5.12 and later don't use SvIVX().
60 * Magic vtables aren't freed when magic is freed, so don't count them.
61 (They are static structures. Anything that assumes otherwise is buggy.)
62 * Reinstate 5.6.x "support". (i.e. it compiles and passes tests.)
63 * Reinstate 5.005_xx "support". (i.e. it compiles and passes tests.)
65 0.75_51 2011-05-05 nicholas
66 * Only use a static array of vtables on gcc.
68 0.75_50 2011-05-04 nicholas
69 * The core's magic vtables are global constants, so aren't part of the size.
70 * Follow mg_obj and mg_ptr.
72 0.75 2011-05-04 nicholas
75 0.74_53 2011-05-01 nicholas
76 * Fix typo error in bit-vector tracking mechanism. On 64 bit platforms which
77 allocate on 8 byte alignment (rather than 16), a low pointer bit could get
78 lost, resulting in new pointers being considered already "seen".
79 "Found" by BinGOs' smoker, fixed on spectre.mongueurs.net. Thanks.
81 0.74_52 2011-04-23 nicholas
82 * Fix potential SEGVs for OP_AELEMFAST on a lexical (eg $foo[3])
83 * Fix likely SEGVs for PVOPs (missing break)
84 * Fix potential SEGVs for PVBMs on 5.10 and later
85 * Move hash and array traversal from total_size() to sv_size()
86 - this allows total_size() and size() to be XS ALIASes.
88 0.74_51 2011-04-22 nicholas
89 * Don't count PL_sv_{undef,no,yes} in the size returned
90 * total_size() was double-counting entries in typeglobs
91 * sv_size() was double-counting the PVGV size if GvEGV() looped back
92 * fix classic off-by-one error - the answer is strlen() + 1, not just strlen()
94 0.74_50 2011-04-19 nicholas
95 * Ensure that size() doesn't add the referent's size for non SVt_RV references
97 0.74 2011-04-19 nicholas
98 * Correct the Makefile.PL - LICENSE was added to ExtUtils::MakeMaker in 6.31
100 0.73_51 2011-04-17 nicholas
101 * Refactor the C code to accumulate the size inside the tracking structure
102 - this means that the C *_size() functions now return void
103 - The XS functions size() and total_size() now return UV, not IV
105 0.73_50 2011-04-17 nicholas
106 * Avoid using assert() on ithreaded 5.8.8 and earlier, as it needs my_perl
107 * Fix the test added in 0.73, as it tripped over a combination of bugs
109 0.73 2011-04-16 nicholas
110 * Revert a bad assertion introduced in 0.72_50, which was logically wrong.
111 - and a test to demonstrate one case that would trigger it
113 0.72_52 2011-04-15 nicholas
114 * Add a test for the non-exceptional warnings.
116 0.72_51 2011-04-15 nicholas
117 * Add PERL_NO_GET_CONTEXT to improve performance under multiplicity
119 0.72_50 2011-04-14 nicholas
120 * Exception handling is totally MSVC specific, so only use it there
121 - this means that we don't need to use a C++ compiler anywhere
122 * Rework bit-vector tracking mechanism to use a 256-way tree. This avoids
123 making assumptions about 64-bit platforms' memory layouts, and eliminates
124 the fatal error introduced in 0.72 when the assumption was violated.
125 * Convert to XSLoader
126 * Resolve CPAN #49437 (Devel::Size adds magic in Perl 5.10)
127 * Resolve CPAN #58484 and #58485 (related to CVs that are XSUBs)
129 0.72 2008-10-14 BrowserUk 70 tests
130 * Added bit-vector pointer tracking mechanism.
131 - new fatal error (64-bit platforms only)
132 * Added exception handling
133 - 4 new warnings (disabled by default)
134 * Updated POD to reflect above
135 * Added basic.t test 13
136 * replaced Module::Install with hand crafted EU::MM Makefile.pl
137 (With many thanks to Sisyphus)
138 because we couldn't work out how to add C++ options to allow
141 0.71 2008-08-24 Tels 69 tests
142 * adapt patch from Reini Urban to fix failing RV under 5.10 and 5.11. AV
143 and HV were pushed directly onto the pending_array, and not the RV,
144 which caused #33530. So he rewrote the logic to deref the RV inside
145 the array traversal. Applied this with one small omission, which
147 * Fixed 5.11 RV/IV logic. (Thanx Reini Urban!)
148 * Removed one duplicate total_size arrayref test. (Thanx Reini Urban!)

152 * fix SEGFAULTS under v5.10 (Thanx Reini Urban!)
153 * fix compilation under blead (Thanx Reini Urban!)

155 about failed compiling on ancient Perls)
156 * update the bundles Module::Install to v0.77
158 0.69 2007-08-11 Tels 69 tests
159 * fix compilation under Perl v5.9.5 and v5.10 (Thanx Steve Peters!)
160 * clarify the license by specifying Perl v5.8.8's license
161 * small doc fixes, add a README file
163 0.68 2007-06-12 Tels 69 tests
164 * remove a bit of duplicate code in op_size, the second instance
166 * fix the failing tests by rewriting the test logic to be sane
167 * the count of array slots was off by one
169 0.67 2007-03-15 Tels 20 tests
170 * rip out Build.PL since it doesn't actually work
171 * fix bug #1653: All SVPV subtype may contain an RV instead of a PV
172 (Thanx a lot Jan, and sorry for the truly horrible long delay!)
173 * fix bug #24846: Does not correctly recurse into references in PVNV
175 * add t/recurse.t that tests the two bugfixes in combination
177 0.66 2007-03-02 Tels 15 tests
178 * fix the failing test (the code was right, but the test wrong)
180 0.65 2007-02-24 Tels 15 tests
181 * fix the test failings under 64 bit (bugs #21037, #18596, #21404)
182 * fix wrong size for strings (bug #17586)
183 * reverse Changelog (bug #16636)
184 * Size.xs: remove unused variable "count"
185 * Size.xs: fix warnings about missing ()
186 * Size.xs: fix size of array refs when AvALLOC == 0
188 + maintained by me, signed with my key
189 + bundle Module::Install and use it
191 + rewrite tests to use Test::More; add more tests

232 - Added in tests from Ken Williams
