1 Revision history for Perl extension Devel::Size.
3 0.79_53 2015-03-25 nicholas
4 * Avoid t/recurse.t failing on earlier versions on 32 bit platforms
5 (subroutines are smaller than it assumes)
6 * Count the size of padlist names in CVs (for v5.18 and later - earlier TODO)
7 * Handle PADNAMELIST/PADNAME introduced in v5.21.7
8 two patches from Zefram:
9 * Add handling of children of METHOP and UNOP_AUX ops [CPAN #102911]
10 * More complete handling of padlists for XSUBs [CPAN #102909]
12 0.79_52 2015-03-20 nicholas
13 two patches from Zefram:
14 * handle the new METHOP. [CPAN #101071]
15 * handle the multideref op, and to a limited extent the UNOP_AUX op class in
16 general. [CPAN #102911]
18 * As of eacbb37937698a03 (v5.21.6), can't call CvPADLIST on an XSUB.
19 More usefully, the slot is now used for XS versioning protection, which
20 means that we can be confident that nothing out there is using it for data.
21 Reported as [CPAN #102909].
22 * Avoid t/recurse.t failing because Test::More::is() has been refactored and
23 is now larger than it was. [CPAN #102910].
25 0.79_51 2015-02-28 nicholas
26 * as of 5.20.0, s/// is no longer a reliable test for OOK [CPAN #95493]
28 0.79_50 2015-02-28 nicholas
30 * wrong test for magicalness [CPAN #88180]
31 * reading tied scalar shrinks it [CPAN #88182]
33 0.79 2013-05-12 nicholas
36 0.78_52 2013-05-10 nicholas
37 * Fix the bug in the previous fix. Oops :-)
39 0.78_51 2013-05-10 nicholas
40 * v5.17.1 and later handle CopSTASH differently under ithreads
42 0.78_50 2013-05-10 nicholas
43 * Alternative test for CvOUTSIDE, and one for CvPADLIST
44 * v5.17 changes the type of PADLIST [CPAN #83904]
45 * stubbed subs no longer have CvOUTSIDE set [CPAN #77913]
46 * Fix for v5.17.2's OP slab allocator [CPAN #83903]
47 * Spelling fix to docs from gregor herrmann [CPAN #78766]
49 0.78 2012-07-26 nicholas
52 0.77_51 2012-07-17 nicholas
53 * Fix for MSVC builds from bulk 88 [CPAN #77589]
55 0.77_50 2012-02-10 nicholas
56 * t/globs.t was failing on 5.15.6 and later due to side effects of a change
57 to strict.pm [CPAN #73998]
58 * skip tests in t/magic.t that use formline on 5.8.1 and 5.8.2, as those
59 versions have a buggy formline that can trigger an assertion failure.
61 0.77 2011-05-16 nicholas
64 0.76_50 2011-05-12 nicholas
65 * Split out HEK size calculation into hek_size(). Add the shared HE overhead.
66 * Handle shared hash key scalars correctly.
67 * GvNAME() is shared from 5.10 onwards.
68 * Count HvNAME(), the HV "aux" struct, the mro_meta struct, and ENAMEs.
70 0.76 2011-05-11 nicholas
71 * Just fix the version number in the line below.
73 0.75_52 2011-05-09 nicholas
74 * Use a table for SV body sizes. These incorporate the space saving post 5.8.x
75 * Correctly handle SvOOK scalars. 5.12 and later don't use SvIVX().
76 * Magic vtables aren't freed when magic is freed, so don't count them.
77 (They are static structures. Anything that assumes otherwise is buggy.)
78 * Reinstate 5.6.x "support". (i.e. it compiles and passes tests.)
79 * Reinstate 5.005_xx "support". (i.e. it compiles and passes tests.)
81 0.75_51 2011-05-05 nicholas
82 * Only use a static array of vtables on gcc.
84 0.75_50 2011-05-04 nicholas
85 * The core's magic vtables are global constants, so aren't part of the size.
86 * Follow mg_obj and mg_ptr.
88 0.75 2011-05-04 nicholas
91 0.74_53 2011-05-01 nicholas
92 * Fix typo error in bit-vector tracking mechanism. On 64 bit platforms which
93 allocate on 8 byte alignment (rather than 16), a low pointer bit could get
94 lost, resulting in new pointers being considered already "seen".
95 "Found" by BinGOs' smoker, fixed on spectre.mongueurs.net. Thanks.
97 0.74_52 2011-04-23 nicholas
98 * Fix potential SEGVs for OP_AELEMFAST on a lexical (eg $foo[3])
99 * Fix likely SEGVs for PVOPs (missing break)
100 * Fix potential SEGVs for PVBMs on 5.10 and later
101 * Move hash and array traversal from total_size() to sv_size()
102 - this allows total_size() and size() to be XS ALIASes.
104 0.74_51 2011-04-22 nicholas
105 * Don't count PL_sv_{undef,no,yes} in the size returned
106 * total_size() was double-counting entries in typeglobs
107 * sv_size() was double-counting the PVGV size if GvEGV() looped back
108 * fix classic off-by-one error - the answer is strlen() + 1, not just strlen()
110 0.74_50 2011-04-19 nicholas
111 * Ensure that size() doesn't add the referent's size for non SVt_RV references
113 0.74 2011-04-19 nicholas
114 * Correct the Makefile.PL - LICENSE was added to ExtUtils::MakeMaker in 6.31
116 0.73_51 2011-04-17 nicholas
117 * Refactor the C code to accumulate the size inside the tracking structure
118 - this means that the C *_size() functions now return void
119 - The XS functions size() and total_size() now return UV, not IV
121 0.73_50 2011-04-17 nicholas
122 * Avoid using assert() on ithreaded 5.8.8 and earlier, as it needs my_perl
123 * Fix the test added in 0.73, as it tripped over a combination of bugs
125 0.73 2011-04-16 nicholas
126 * Revert a bad assertion introduced in 0.72_50, which was logically wrong.
127 - and a test to demonstrate one case that would trigger it
129 0.72_52 2011-04-15 nicholas
130 * Add a test for the non-exceptional warnings.
132 0.72_51 2011-04-15 nicholas
133 * Add PERL_NO_GET_CONTEXT to improve performance under multiplicity
135 0.72_50 2011-04-14 nicholas
136 * Exception handling is totally MSVC specific, so only use it there
137 - this means that we don't need to use a C++ compiler anywhere
138 * Rework bit-vector tracking mechanism to use a 256-way tree. This avoids
139 making assumptions about 64-bit platforms' memory layouts, and eliminates
140 the fatal error introduced in 0.72 when the assumption was violated.
141 * Convert to XSLoader
142 * Resolve CPAN #49437 (Devel::Size adds magic in Perl 5.10)
143 * Resolve CPAN #58484 and #58485 (related to CVs that are XSUBs)
145 0.72 2008-10-14 BrowserUk 70 tests
146 * Added bit-vector pointer tracking mechanism.
147 - new fatal error (64-bit platforms only)
148 * Added exception handling
149 - 4 new warnings (disabled by default)
150 * Updated POD to reflect above
151 * Added basic.t test 13
152 * replaced Module::Install with hand crafted EU::MM Makefile.pl
153 (With many thanks to Sisyphus)
154 because we couldn't work out how to add C++ options to allow
157 0.71 2008-08-24 Tels 69 tests
158 * adapt patch from Reini Urban to fix failing RV under 5.10 and 5.11. AV
159 and HV were pushed directly onto the pending_array, and not the RV,
160 which caused #33530. So he rewrote the logic to deref the RV inside
161 the array traversal. Applied this with one small omission, which
163 * Fixed 5.11 RV/IV logic. (Thanx Reini Urban!)
164 * Removed one duplicate total_size arrayref test. (Thanx Reini Urban!)
165 * changed //printf to dbg_printf() (Thanx Reini again!)
167 0.70 2008-08-23 Tels 69 tests
168 * fix SEGFAULTS under v5.10 (Thanx Reini Urban!)
169 * fix compilation under blead (Thanx Reini Urban!)
170 * require Perl 5.006 (to stop CPANTESTERS sending bogus reports
171 about failed compiling on ancient Perls)
172 * update the bundles Module::Install to v0.77
174 0.69 2007-08-11 Tels 69 tests
175 * fix compilation under Perl v5.9.5 and v5.10 (Thanx Steve Peters!)
176 * clarify the license by specifying Perl v5.8.8's license
177 * small doc fixes, add a README file
179 0.68 2007-06-12 Tels 69 tests
180 * remove a bit of duplicate code in op_size, the second instance
182 * fix the failing tests by rewriting the test logic to be sane
183 * the count of array slots was off by one
185 0.67 2007-03-15 Tels 20 tests
186 * rip out Build.PL since it doesn't actually work
187 * fix bug #1653: All SVPV subtype may contain an RV instead of a PV
188 (Thanx a lot Jan, and sorry for the truly horrible long delay!)
189 * fix bug #24846: Does not correctly recurse into references in PVNV
191 * add t/recurse.t that tests the two bugfixes in combination
193 0.66 2007-03-02 Tels 15 tests
194 * fix the failing test (the code was right, but the test wrong)
196 0.65 2007-02-24 Tels 15 tests
197 * fix the test failings under 64 bit (bugs #21037, #18596, #21404)
198 * fix wrong size for strings (bug #17586)
199 * reverse Changelog (bug #16636)
200 * Size.xs: remove unused variable "count"
201 * Size.xs: fix warnings about missing ()
202 * Size.xs: fix size of array refs when AvALLOC == 0
204 + maintained by me, signed with my key
205 + bundle Module::Install and use it
207 + rewrite tests to use Test::More; add more tests

214 0.63 Thu Jun 30 14:29:43 2005
215 - Turns out that OP_TRANS is a basic op, not a loop op. This

236 of Marcus Holland-Moritz <mhx-perl@gmx.net>)

247 memory that Devel::Size can't see.
248 - Added in tests from Ken Williams
