1 Revision history for Perl extension Devel::Size.
3 0.77_50 2012-02-10 nicholas
4 * t/globs.t was failing on 5.15.6 and later due to side effects of a change
5 to strict.pm [CPAN #73998]
7 0.77 2011-05-16 nicholas
10 0.76_50 2011-05-12 nicholas
11 * Split out HEK size calculation into hek_size(). Add the shared HE overhead.
12 * Handle shared hash key scalars correctly.
13 * GvNAME() is shared from 5.10 onwards.
14 * Count HvNAME(), the HV "aux" struct, the mro_meta struct, and ENAMEs.
16 0.76 2011-05-11 nicholas
17 * Just fix the version number in the line below.
19 0.75_52 2011-05-09 nicholas
20 * Use a table for SV body sizes. These incorporate the space saving post 5.8.x
21 * Correctly handle SvOOK scalars. 5.12 and later don't use SvIVX().
22 * Magic vtables aren't freed when magic is freed, so don't count them.
23 (They are static structures. Anything that assumes otherwise is buggy.)
24 * Reinstate 5.6.x "support". (i.e. it compiles and passes tests.)
25 * Reinstate 5.005_xx "support". (i.e. it compiles and passes tests.)
27 0.75_51 2011-05-05 nicholas
28 * Only use a static array of vtables on gcc.
30 0.75_50 2011-05-04 nicholas
31 * The core's magic vtables are global constants, so aren't part of the size.
32 * Follow mg_obj and mg_ptr.
34 0.75 2011-05-04 nicholas
37 0.74_53 2011-05-01 nicholas
38 * Fix typo error in bit-vector tracking mechanism. On 64 bit platforms which
39 allocate on 8 byte alignment (rather than 16), a low pointer bit could get
40 lost, resulting in new pointers being considered already "seen".
41 "Found" by BinGOs' smoker, fixed on spectre.mongueurs.net. Thanks.
43 0.74_52 2011-04-23 nicholas
44 * Fix potential SEGVs for OP_AELEMFAST on a lexical (eg $foo[3])
45 * Fix likely SEGVs for PVOPs (missing break)
46 * Fix potential SEGVs for PVBMs on 5.10 and later
47 * Move hash and array traversal from total_size() to sv_size()
48 - this allows total_size() and size() to be XS ALIASes.
50 0.74_51 2011-04-22 nicholas
51 * Don't count PL_sv_{undef,no,yes} in the size returned
52 * total_size() was double-counting entries in typeglobs
53 * sv_size() was double-counting the PVGV size if GvEGV() looped back
54 * fix classic off-by-one error - the answer is strlen() + 1, not just strlen()
56 0.74_50 2011-04-19 nicholas
57 * Ensure that size() doesn't add the referent's size for non SVt_RV references
59 0.74 2011-04-19 nicholas
60 * Correct the Makefile.PL - LICENSE was added to ExtUtils::MakeMaker in 6.31
62 0.73_51 2011-04-17 nicholas
63 * Refactor the C code to accumulate the size inside the tracking structure
64 - this means that the C *_size() functions now return void
65 - The XS functions size() and total_size() now return UV, not IV
67 0.73_50 2011-04-17 nicholas
68 * Avoid using assert() on ithreaded 5.8.8 and earlier, as it needs my_perl
69 * Fix the test added in 0.73, as it tripped over a combination of bugs
71 0.73 2011-04-16 nicholas
72 * Revert a bad assertion introduced in 0.72_50, which was logically wrong.
73 - and a test to demonstrate one case that would trigger it
75 0.72_52 2011-04-15 nicholas
76 * Add a test for the non-exceptional warnings.
78 0.72_51 2011-04-15 nicholas
79 * Add PERL_NO_GET_CONTEXT to improve performance under multiplicity
81 0.72_50 2011-04-14 nicholas
82 * Exception handling is totally MSVC specific, so only use it there
83 - this means that we don't need to use a C++ compiler anywhere
84 * Rework bit-vector tracking mechanism to use a 256-way tree. This avoids
85 making assumptions about 64-bit platforms' memory layouts, and eliminates
86 the fatal error introduced in 0.72 when the assumption was violated.
88 * Resolve CPAN #49437 (Devel::Size adds magic in Perl 5.10)
89 * Resolve CPAN #58484 and #58485 (related to CVs that are XSUBs)
91 0.72 2008-10-14 BrowserUk 70 tests
92 * Added bit-vector pointer tracking mechanism.
93 - new fatal error (64-bit platforms only)
94 * Added exception handling
95 - 4 new warnings (disabled by default)
96 * Updated POD to reflect above
97 * Added basic.t test 13
98 * replaced Module::Install with hand crafted EU::MM Makefile.pl
99 (With many thanks to Sisyphus)
100 because we couldn't work out how to add C++ options to allow
103 0.71 2008-08-24 Tels 69 tests
104 * adapt patch from Reini Urban to fix failing RV under 5.10 and 5.11. AV
105 and HV were pushed directly onto the pending_array, and not the RV,
106 which caused #33530. So he rewrote the logic to deref the RV inside
107 the array traversal. Applied this with one small omission, which
109 * Fixed 5.11 RV/IV logic. (Thanx Reini Urban!)
110 * Removed one duplicate total_size arrayref test. (Thanx Reini Urban!)
111 * changed //printf to dbg_printf() (Thanx Reini again!)
113 0.70 2008-08-23 Tels 69 tests
114 * fix SEGFAULTS under v5.10 (Thanx Reini Urban!)
115 * fix compilation under blead (Thanx Reini Urban!)
116 * require Perl 5.006 (to stop CPANTESTERS sending bogus reports
117 about failed compiling on ancient Perls)
118 * update the bundles Module::Install to v0.77
120 0.69 2007-08-11 Tels 69 tests
121 * fix compilation under Perl v5.9.5 and v5.10 (Thanx Steve Peters!)
122 * clarify the license by specifying Perl v5.8.8's license
123 * small doc fixes, add a README file
125 0.68 2007-06-12 Tels 69 tests
126 * remove a bit of duplicate code in op_size, the second instance
128 * fix the failing tests by rewriting the test logic to be sane
129 * the count of array slots was off by one
131 0.67 2007-03-15 Tels 20 tests
132 * rip out Build.PL since it doesn't actually work
133 * fix bug #1653: All SVPV subtype may contain an RV instead of a PV
134 (Thanx a lot Jan, and sorry for the truly horrible long delay!)
135 * fix bug #24846: Does not correctly recurse into references in PVNV
137 * add t/recurse.t that tests the two bugfixes in combination
139 0.66 2007-03-02 Tels 15 tests
140 * fix the failing test (the code was right, but the test wrong)
142 0.65 2007-02-24 Tels 15 tests
143 * fix the test failings under 64 bit (bugs #21037, #18596, #21404)
144 * fix wrong size for strings (bug #17586)
145 * reverse Changelog (bug #16636)
146 * Size.xs: remove unused variable "count"
147 * Size.xs: fix warnings about missing ()
148 * Size.xs: fix size of array refs when AvALLOC == 0
150 + maintained by me, signed with my key
151 + bundle Module::Install and use it
153 + rewrite tests to use Test::More; add more tests
