1 Revision history for Perl extension Devel::Size.
3 0.72_52 2011-05-09 nicholas
4 * Use a table for SV body sizes. These incorporate the space saving post 5.8.x
5 * Correctly handle SvOOK scalars. 5.12 and later don't use SvIVX().
6 * Magic vtables aren't freed when magic is freed, so don't count them.
7 (They are static structures. Anything that assumes otherwise is buggy.)
9 0.75_51 2011-05-05 nicholas
10 * Only use a static array of vtables on gcc.
12 0.75_50 2011-05-04 nicholas
13 * The core's magic vtables are global constants, so aren't part of the size.
14 * Follow mg_obj and mg_ptr.
16 0.75 2011-05-04 nicholas
19 0.74_53 2011-05-01 nicholas
20 * Fix typo error in bit-vector tracking mechanism. On 64 bit platforms which
21 allocate on 8 byte alignment (rather than 16), a low pointer bit could get
22 lost, resulting in new pointers being considered already "seen".
23 "Found" by BinGOs' smoker, fixed on spectre.mongueurs.net. Thanks.
25 0.74_52 2011-04-23 nicholas
26 * Fix potential SEGVs for OP_AELEMFAST on a lexical (eg $foo[3])
27 * Fix likely SEGVs for PVOPs (missing break)
28 * Fix potential SEGVs for PVBMs on 5.10 and later
29 * Move hash and array traversal from total_size() to sv_size()
30 - this allows total_size() and size() to be XS ALIASes.
32 0.74_51 2011-04-22 nicholas
33 * Don't count PL_sv_{undef,no,yes} in the size returned
34 * total_size() was double-counting entries in typeglobs
35 * sv_size() was double-counting the PVGV size if GvEGV() looped back
36 * fix classic off-by-one error - the answer is strlen() + 1, not just strlen()
38 0.74_50 2011-04-19 nicholas
39 * Ensure that size() doesn't add the referent's size for non SVt_RV references
41 0.74 2011-04-19 nicholas
42 * Correct the Makefile.PL - LICENSE was added to ExtUtils::MakeMaker in 6.31
44 0.73_51 2011-04-17 nicholas
45 * Refactor the C code to accumulate the size inside the tracking structure
46 - this means that the C *_size() functions now return void
47 - The XS functions size() and total_size() now return UV, not IV
49 0.73_50 2011-04-17 nicholas
50 * Avoid using assert() on ithreaded 5.8.8 and earlier, as it needs my_perl
51 * Fix the test added in 0.73, as it tripped over a combination of bugs
53 0.73 2011-04-16 nicholas
54 * Revert a bad assertion introduced in 0.72_50, which was logically wrong.
55 - and a test to demonstrate one case that would trigger it
57 0.72_52 2011-04-15 nicholas
58 * Add a test for the non-exceptional warnings.
60 0.72_51 2011-04-15 nicholas
61 * Add PERL_NO_GET_CONTEXT to improve performance under multiplicity
63 0.72_50 2011-04-14 nicholas
64 * Exception handling is totally MSVC specific, so only use it there
65 - this means that we don't need to use a C++ compiler anywhere
66 * Rework bit-vector tracking mechanism to use a 256-way tree. This avoids
67 making assumptions about 64-bit platforms' memory layouts, and eliminates
68 the fatal error introduced in 0.72 when the assumption was violated.
70 * Resolve CPAN #49437 (Devel::Size adds magic in Perl 5.10)
71 * Resolve CPAN #58484 and #58485 (related to CVs that are XSUBs)
73 0.72 2008-10-14 BrowserUk 70 tests
74 * Added bit-vector pointer tracking mechanism.
75 - new fatal error (64-bit platforms only)
76 * Added exception handling
77 - 4 new warnings (disabled by default)
78 * Updated POD to reflect above
79 * Added basic.t test 13
80 * replaced Module::Install with hand crafted EU::MM Makefile.pl
81 (With many thanks to Sisyphus)
82 because we couldn't work out how to add C++ options to allow
85 0.71 2008-08-24 Tels 69 tests
86 * adapt patch from Reini Urban to fix failing RV under 5.10 and 5.11. AV
87 and HV were pushed directly onto the pending_array, and not the RV,
88 which caused #33530. So he rewrote the logic to deref the RV inside
89 the array traversal. Applied this with one small omission, which
91 * Fixed 5.11 RV/IV logic. (Thanx Reini Urban!)
92 * Removed one duplicate total_size arrayref test. (Thanx Reini Urban!)
93 * changed //printf to dbg_printf() (Thanx Reini again!)
95 0.70 2008-08-23 Tels 69 tests
96 * fix SEGFAULTS under v5.10 (Thanx Reini Urban!)
97 * fix compilation under blead (Thanx Reini Urban!)
98 * require Perl 5.006 (to stop CPANTESTERS sending bogus reports
99 about failed compiling on ancient Perls)
100 * update the bundles Module::Install to v0.77
102 0.69 2007-08-11 Tels 69 tests
103 * fix compilation under Perl v5.9.5 and v5.10 (Thanx Steve Peters!)
104 * clarify the license by specifying Perl v5.8.8's license
105 * small doc fixes, add a README file
107 0.68 2007-06-12 Tels 69 tests
108 * remove a bit of duplicate code in op_size, the second instance
110 * fix the failing tests by rewriting the test logic to be sane
111 * the count of array slots was off by one
113 0.67 2007-03-15 Tels 20 tests
114 * rip out Build.PL since it doesn't actually work
115 * fix bug #1653: All SVPV subtype may contain an RV instead of a PV
116 (Thanx a lot Jan, and sorry for the truly horrible long delay!)
117 * fix bug #24846: Does not correctly recurse into references in PVNV
119 * add t/recurse.t that tests the two bugfixes in combination
121 0.66 2007-03-02 Tels 15 tests
122 * fix the failing test (the code was right, but the test wrong)
124 0.65 2007-02-24 Tels 15 tests
125 * fix the test failings under 64 bit (bugs #21037, #18596, #21404)
126 * fix wrong size for strings (bug #17586)
127 * reverse Changelog (bug #16636)
128 * Size.xs: remove unused variable "count"
129 * Size.xs: fix warnings about missing ()
130 * Size.xs: fix size of array refs when AvALLOC == 0
132 + maintained by me, signed with my key
133 + bundle Module::Install and use it
135 + rewrite tests to use Test::More; add more tests
