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)
7 0.79_52 2015-03-20 nicholas
8 two patches from Zefram:
9 * handle the new METHOP. [CPAN #101071]
10 * handle the multideref op, and to a limited extent the UNOP_AUX op class in
11 general. [CPAN #102911]
13 * As of eacbb37937698a03 (v5.21.6), can't call CvPADLIST on an XSUB.
14 More usefully, the slot is now used for XS versioning protection, which
15 means that we can be confident that nothing out there is using it for data.
16 Reported as [CPAN #102909].
17 * Avoid t/recurse.t failing because Test::More::is() has been refactored and
18 is now larger than it was. [CPAN #102910].
20 0.79_51 2015-02-28 nicholas
21 * as of 5.20.0, s/// is no longer a reliable test for OOK [CPAN #95493]
23 0.79_50 2015-02-28 nicholas
25 * wrong test for magicalness [CPAN #88180]
26 * reading tied scalar shrinks it [CPAN #88182]
28 0.79 2013-05-12 nicholas
31 0.78_52 2013-05-10 nicholas
32 * Fix the bug in the previous fix. Oops :-)
34 0.78_51 2013-05-10 nicholas
35 * v5.17.1 and later handle CopSTASH differently under ithreads
37 0.78_50 2013-05-10 nicholas
38 * Alternative test for CvOUTSIDE, and one for CvPADLIST
39 * v5.17 changes the type of PADLIST [CPAN #83904]
40 * stubbed subs no longer have CvOUTSIDE set [CPAN #77913]
41 * Fix for v5.17.2's OP slab allocator [CPAN #83903]
42 * Spelling fix to docs from gregor herrmann [CPAN #78766]
44 0.78 2012-07-26 nicholas
47 0.77_51 2012-07-17 nicholas
48 * Fix for MSVC builds from bulk 88 [CPAN #77589]
50 0.77_50 2012-02-10 nicholas
51 * t/globs.t was failing on 5.15.6 and later due to side effects of a change
52 to strict.pm [CPAN #73998]
53 * skip tests in t/magic.t that use formline on 5.8.1 and 5.8.2, as those
54 versions have a buggy formline that can trigger an assertion failure.
56 0.77 2011-05-16 nicholas
59 0.76_50 2011-05-12 nicholas
60 * Split out HEK size calculation into hek_size(). Add the shared HE overhead.
61 * Handle shared hash key scalars correctly.
62 * GvNAME() is shared from 5.10 onwards.
63 * Count HvNAME(), the HV "aux" struct, the mro_meta struct, and ENAMEs.
65 0.76 2011-05-11 nicholas
66 * Just fix the version number in the line below.
68 0.75_52 2011-05-09 nicholas
69 * Use a table for SV body sizes. These incorporate the space saving post 5.8.x
70 * Correctly handle SvOOK scalars. 5.12 and later don't use SvIVX().
71 * Magic vtables aren't freed when magic is freed, so don't count them.
72 (They are static structures. Anything that assumes otherwise is buggy.)
73 * Reinstate 5.6.x "support". (i.e. it compiles and passes tests.)
74 * Reinstate 5.005_xx "support". (i.e. it compiles and passes tests.)
76 0.75_51 2011-05-05 nicholas
77 * Only use a static array of vtables on gcc.
79 0.75_50 2011-05-04 nicholas
80 * The core's magic vtables are global constants, so aren't part of the size.
81 * Follow mg_obj and mg_ptr.
83 0.75 2011-05-04 nicholas
86 0.74_53 2011-05-01 nicholas
87 * Fix typo error in bit-vector tracking mechanism. On 64 bit platforms which
88 allocate on 8 byte alignment (rather than 16), a low pointer bit could get
89 lost, resulting in new pointers being considered already "seen".
90 "Found" by BinGOs' smoker, fixed on spectre.mongueurs.net. Thanks.
92 0.74_52 2011-04-23 nicholas
93 * Fix potential SEGVs for OP_AELEMFAST on a lexical (eg $foo[3])
94 * Fix likely SEGVs for PVOPs (missing break)
95 * Fix potential SEGVs for PVBMs on 5.10 and later
96 * Move hash and array traversal from total_size() to sv_size()
97 - this allows total_size() and size() to be XS ALIASes.
99 0.74_51 2011-04-22 nicholas
100 * Don't count PL_sv_{undef,no,yes} in the size returned
101 * total_size() was double-counting entries in typeglobs
102 * sv_size() was double-counting the PVGV size if GvEGV() looped back
103 * fix classic off-by-one error - the answer is strlen() + 1, not just strlen()
105 0.74_50 2011-04-19 nicholas
106 * Ensure that size() doesn't add the referent's size for non SVt_RV references
108 0.74 2011-04-19 nicholas
109 * Correct the Makefile.PL - LICENSE was added to ExtUtils::MakeMaker in 6.31
111 0.73_51 2011-04-17 nicholas
112 * Refactor the C code to accumulate the size inside the tracking structure
113 - this means that the C *_size() functions now return void
114 - The XS functions size() and total_size() now return UV, not IV
116 0.73_50 2011-04-17 nicholas
117 * Avoid using assert() on ithreaded 5.8.8 and earlier, as it needs my_perl
118 * Fix the test added in 0.73, as it tripped over a combination of bugs
120 0.73 2011-04-16 nicholas
121 * Revert a bad assertion introduced in 0.72_50, which was logically wrong.
122 - and a test to demonstrate one case that would trigger it
124 0.72_52 2011-04-15 nicholas
125 * Add a test for the non-exceptional warnings.
127 0.72_51 2011-04-15 nicholas
128 * Add PERL_NO_GET_CONTEXT to improve performance under multiplicity
130 0.72_50 2011-04-14 nicholas
131 * Exception handling is totally MSVC specific, so only use it there
132 - this means that we don't need to use a C++ compiler anywhere
133 * Rework bit-vector tracking mechanism to use a 256-way tree. This avoids
134 making assumptions about 64-bit platforms' memory layouts, and eliminates
135 the fatal error introduced in 0.72 when the assumption was violated.
136 * Convert to XSLoader
137 * Resolve CPAN #49437 (Devel::Size adds magic in Perl 5.10)
138 * Resolve CPAN #58484 and #58485 (related to CVs that are XSUBs)
140 0.72 2008-10-14 BrowserUk 70 tests
141 * Added bit-vector pointer tracking mechanism.
142 - new fatal error (64-bit platforms only)
143 * Added exception handling
144 - 4 new warnings (disabled by default)
145 * Updated POD to reflect above
146 * Added basic.t test 13
147 * replaced Module::Install with hand crafted EU::MM Makefile.pl
148 (With many thanks to Sisyphus)
149 because we couldn't work out how to add C++ options to allow
152 0.71 2008-08-24 Tels 69 tests
153 * adapt patch from Reini Urban to fix failing RV under 5.10 and 5.11. AV
154 and HV were pushed directly onto the pending_array, and not the RV,
155 which caused #33530. So he rewrote the logic to deref the RV inside
156 the array traversal. Applied this with one small omission, which
158 * Fixed 5.11 RV/IV logic. (Thanx Reini Urban!)
159 * Removed one duplicate total_size arrayref test. (Thanx Reini Urban!)
160 * changed //printf to dbg_printf() (Thanx Reini again!)
162 0.70 2008-08-23 Tels 69 tests
163 * fix SEGFAULTS under v5.10 (Thanx Reini Urban!)
164 * fix compilation under blead (Thanx Reini Urban!)
165 * require Perl 5.006 (to stop CPANTESTERS sending bogus reports
166 about failed compiling on ancient Perls)
167 * update the bundles Module::Install to v0.77
169 0.69 2007-08-11 Tels 69 tests
170 * fix compilation under Perl v5.9.5 and v5.10 (Thanx Steve Peters!)
171 * clarify the license by specifying Perl v5.8.8's license
172 * small doc fixes, add a README file
174 0.68 2007-06-12 Tels 69 tests
175 * remove a bit of duplicate code in op_size, the second instance
177 * fix the failing tests by rewriting the test logic to be sane
178 * the count of array slots was off by one
180 0.67 2007-03-15 Tels 20 tests
181 * rip out Build.PL since it doesn't actually work
182 * fix bug #1653: All SVPV subtype may contain an RV instead of a PV
183 (Thanx a lot Jan, and sorry for the truly horrible long delay!)
184 * fix bug #24846: Does not correctly recurse into references in PVNV
186 * add t/recurse.t that tests the two bugfixes in combination
188 0.66 2007-03-02 Tels 15 tests
189 * fix the failing test (the code was right, but the test wrong)
191 0.65 2007-02-24 Tels 15 tests
192 * fix the test failings under 64 bit (bugs #21037, #18596, #21404)
193 * fix wrong size for strings (bug #17586)
194 * reverse Changelog (bug #16636)
195 * Size.xs: remove unused variable "count"
196 * Size.xs: fix warnings about missing ()
197 * Size.xs: fix size of array refs when AvALLOC == 0
199 + maintained by me, signed with my key
200 + bundle Module::Install and use it
202 + rewrite tests to use Test::More; add more tests

209 0.63 Thu Jun 30 14:29:43 2005
210 - Turns out that OP_TRANS is a basic op, not a loop op. This

228 0.58 Fri Jul 18 11:42:32 2003
229 - Fix for problems triggered by perl 5.8.0 and up, more tests, and
230 removal of an "our" for better backwards compatibility. (Courtesy
231 of Marcus Holland-Moritz <mhx-perl@gmx.net>)
233 0.57 Thu Mar 20 13:21:14 2003

239 0.55 Sat Feb 22 17:21:00 2003
240 - Fixed a bad size calculation (we were overestimating by one byte)
241 - Updated the docs to show some of the places that there might be 'dark'
242 memory that Devel::Size can't see.
243 - Added in tests from Ken Williams
245 0.54 Sat Oct 12 14:11:00 2002
