1 Revision history for Perl extension Devel::Size.
3 0.76_50 2011-05-12 nicholas
4 * Split out HEK size calculation into hek_size(). Add the shared HE overhead.
5 * Handle shared hash key scalars correctly.
6 * GvNAME() is shared from 5.10 onwards.
8 0.76 2011-05-11 nicholas
9 * Just fix the version number in the line below.
11 0.75_52 2011-05-09 nicholas
12 * Use a table for SV body sizes. These incorporate the space saving post 5.8.x
13 * Correctly handle SvOOK scalars. 5.12 and later don't use SvIVX().
14 * Magic vtables aren't freed when magic is freed, so don't count them.
15 (They are static structures. Anything that assumes otherwise is buggy.)
16 * Reinstate 5.6.x "support". (i.e. it compiles and passes tests.)
17 * Reinstate 5.005_xx "support". (i.e. it compiles and passes tests.)
19 0.75_51 2011-05-05 nicholas
20 * Only use a static array of vtables on gcc.
22 0.75_50 2011-05-04 nicholas
23 * The core's magic vtables are global constants, so aren't part of the size.
24 * Follow mg_obj and mg_ptr.
26 0.75 2011-05-04 nicholas
29 0.74_53 2011-05-01 nicholas
30 * Fix typo error in bit-vector tracking mechanism. On 64 bit platforms which
31 allocate on 8 byte alignment (rather than 16), a low pointer bit could get
32 lost, resulting in new pointers being considered already "seen".
33 "Found" by BinGOs' smoker, fixed on spectre.mongueurs.net. Thanks.
35 0.74_52 2011-04-23 nicholas
36 * Fix potential SEGVs for OP_AELEMFAST on a lexical (eg $foo[3])
37 * Fix likely SEGVs for PVOPs (missing break)
38 * Fix potential SEGVs for PVBMs on 5.10 and later
39 * Move hash and array traversal from total_size() to sv_size()
40 - this allows total_size() and size() to be XS ALIASes.
42 0.74_51 2011-04-22 nicholas
43 * Don't count PL_sv_{undef,no,yes} in the size returned
44 * total_size() was double-counting entries in typeglobs
45 * sv_size() was double-counting the PVGV size if GvEGV() looped back
46 * fix classic off-by-one error - the answer is strlen() + 1, not just strlen()
48 0.74_50 2011-04-19 nicholas
49 * Ensure that size() doesn't add the referent's size for non SVt_RV references
51 0.74 2011-04-19 nicholas
52 * Correct the Makefile.PL - LICENSE was added to ExtUtils::MakeMaker in 6.31
54 0.73_51 2011-04-17 nicholas
55 * Refactor the C code to accumulate the size inside the tracking structure
56 - this means that the C *_size() functions now return void
57 - The XS functions size() and total_size() now return UV, not IV
59 0.73_50 2011-04-17 nicholas
60 * Avoid using assert() on ithreaded 5.8.8 and earlier, as it needs my_perl
61 * Fix the test added in 0.73, as it tripped over a combination of bugs
63 0.73 2011-04-16 nicholas
64 * Revert a bad assertion introduced in 0.72_50, which was logically wrong.
65 - and a test to demonstrate one case that would trigger it
67 0.72_52 2011-04-15 nicholas
68 * Add a test for the non-exceptional warnings.
70 0.72_51 2011-04-15 nicholas
71 * Add PERL_NO_GET_CONTEXT to improve performance under multiplicity
73 0.72_50 2011-04-14 nicholas
74 * Exception handling is totally MSVC specific, so only use it there
75 - this means that we don't need to use a C++ compiler anywhere
76 * Rework bit-vector tracking mechanism to use a 256-way tree. This avoids
77 making assumptions about 64-bit platforms' memory layouts, and eliminates
78 the fatal error introduced in 0.72 when the assumption was violated.
80 * Resolve CPAN #49437 (Devel::Size adds magic in Perl 5.10)
81 * Resolve CPAN #58484 and #58485 (related to CVs that are XSUBs)
83 0.72 2008-10-14 BrowserUk 70 tests
84 * Added bit-vector pointer tracking mechanism.
85 - new fatal error (64-bit platforms only)
86 * Added exception handling
87 - 4 new warnings (disabled by default)
88 * Updated POD to reflect above
89 * Added basic.t test 13
90 * replaced Module::Install with hand crafted EU::MM Makefile.pl
91 (With many thanks to Sisyphus)
92 because we couldn't work out how to add C++ options to allow
95 0.71 2008-08-24 Tels 69 tests
96 * adapt patch from Reini Urban to fix failing RV under 5.10 and 5.11. AV
97 and HV were pushed directly onto the pending_array, and not the RV,
98 which caused #33530. So he rewrote the logic to deref the RV inside
99 the array traversal. Applied this with one small omission, which
101 * Fixed 5.11 RV/IV logic. (Thanx Reini Urban!)
102 * Removed one duplicate total_size arrayref test. (Thanx Reini Urban!)
103 * changed //printf to dbg_printf() (Thanx Reini again!)
105 0.70 2008-08-23 Tels 69 tests
106 * fix SEGFAULTS under v5.10 (Thanx Reini Urban!)
107 * fix compilation under blead (Thanx Reini Urban!)
108 * require Perl 5.006 (to stop CPANTESTERS sending bogus reports
109 about failed compiling on ancient Perls)
110 * update the bundles Module::Install to v0.77
112 0.69 2007-08-11 Tels 69 tests
113 * fix compilation under Perl v5.9.5 and v5.10 (Thanx Steve Peters!)
114 * clarify the license by specifying Perl v5.8.8's license
115 * small doc fixes, add a README file
117 0.68 2007-06-12 Tels 69 tests
118 * remove a bit of duplicate code in op_size, the second instance
120 * fix the failing tests by rewriting the test logic to be sane
121 * the count of array slots was off by one
123 0.67 2007-03-15 Tels 20 tests
124 * rip out Build.PL since it doesn't actually work
125 * fix bug #1653: All SVPV subtype may contain an RV instead of a PV
126 (Thanx a lot Jan, and sorry for the truly horrible long delay!)
127 * fix bug #24846: Does not correctly recurse into references in PVNV
129 * add t/recurse.t that tests the two bugfixes in combination
131 0.66 2007-03-02 Tels 15 tests
132 * fix the failing test (the code was right, but the test wrong)
134 0.65 2007-02-24 Tels 15 tests
135 * fix the test failings under 64 bit (bugs #21037, #18596, #21404)
136 * fix wrong size for strings (bug #17586)
137 * reverse Changelog (bug #16636)
138 * Size.xs: remove unused variable "count"
139 * Size.xs: fix warnings about missing ()
140 * Size.xs: fix size of array refs when AvALLOC == 0
142 + maintained by me, signed with my key
143 + bundle Module::Install and use it
145 + rewrite tests to use Test::More; add more tests
