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.
6 0.76 2011-05-11 nicholas
7 * Just fix the version number in the line below.
9 0.75_52 2011-05-09 nicholas
10 * Use a table for SV body sizes. These incorporate the space saving post 5.8.x
11 * Correctly handle SvOOK scalars. 5.12 and later don't use SvIVX().
12 * Magic vtables aren't freed when magic is freed, so don't count them.
13 (They are static structures. Anything that assumes otherwise is buggy.)
14 * Reinstate 5.6.x "support". (i.e. it compiles and passes tests.)
15 * Reinstate 5.005_xx "support". (i.e. it compiles and passes tests.)
17 0.75_51 2011-05-05 nicholas
18 * Only use a static array of vtables on gcc.
20 0.75_50 2011-05-04 nicholas
21 * The core's magic vtables are global constants, so aren't part of the size.
22 * Follow mg_obj and mg_ptr.
24 0.75 2011-05-04 nicholas
27 0.74_53 2011-05-01 nicholas
28 * Fix typo error in bit-vector tracking mechanism. On 64 bit platforms which
29 allocate on 8 byte alignment (rather than 16), a low pointer bit could get
30 lost, resulting in new pointers being considered already "seen".
31 "Found" by BinGOs' smoker, fixed on spectre.mongueurs.net. Thanks.
33 0.74_52 2011-04-23 nicholas
34 * Fix potential SEGVs for OP_AELEMFAST on a lexical (eg $foo[3])
35 * Fix likely SEGVs for PVOPs (missing break)
36 * Fix potential SEGVs for PVBMs on 5.10 and later
37 * Move hash and array traversal from total_size() to sv_size()
38 - this allows total_size() and size() to be XS ALIASes.
40 0.74_51 2011-04-22 nicholas
41 * Don't count PL_sv_{undef,no,yes} in the size returned
42 * total_size() was double-counting entries in typeglobs
43 * sv_size() was double-counting the PVGV size if GvEGV() looped back
44 * fix classic off-by-one error - the answer is strlen() + 1, not just strlen()
46 0.74_50 2011-04-19 nicholas
47 * Ensure that size() doesn't add the referent's size for non SVt_RV references
49 0.74 2011-04-19 nicholas
50 * Correct the Makefile.PL - LICENSE was added to ExtUtils::MakeMaker in 6.31
52 0.73_51 2011-04-17 nicholas
53 * Refactor the C code to accumulate the size inside the tracking structure
54 - this means that the C *_size() functions now return void
55 - The XS functions size() and total_size() now return UV, not IV
57 0.73_50 2011-04-17 nicholas
58 * Avoid using assert() on ithreaded 5.8.8 and earlier, as it needs my_perl
59 * Fix the test added in 0.73, as it tripped over a combination of bugs
61 0.73 2011-04-16 nicholas
62 * Revert a bad assertion introduced in 0.72_50, which was logically wrong.
63 - and a test to demonstrate one case that would trigger it
65 0.72_52 2011-04-15 nicholas
66 * Add a test for the non-exceptional warnings.
68 0.72_51 2011-04-15 nicholas
69 * Add PERL_NO_GET_CONTEXT to improve performance under multiplicity
71 0.72_50 2011-04-14 nicholas
72 * Exception handling is totally MSVC specific, so only use it there
73 - this means that we don't need to use a C++ compiler anywhere
74 * Rework bit-vector tracking mechanism to use a 256-way tree. This avoids
75 making assumptions about 64-bit platforms' memory layouts, and eliminates
76 the fatal error introduced in 0.72 when the assumption was violated.
78 * Resolve CPAN #49437 (Devel::Size adds magic in Perl 5.10)
79 * Resolve CPAN #58484 and #58485 (related to CVs that are XSUBs)
81 0.72 2008-10-14 BrowserUk 70 tests
82 * Added bit-vector pointer tracking mechanism.
83 - new fatal error (64-bit platforms only)
84 * Added exception handling
85 - 4 new warnings (disabled by default)
86 * Updated POD to reflect above
87 * Added basic.t test 13
88 * replaced Module::Install with hand crafted EU::MM Makefile.pl
89 (With many thanks to Sisyphus)
90 because we couldn't work out how to add C++ options to allow
93 0.71 2008-08-24 Tels 69 tests
94 * adapt patch from Reini Urban to fix failing RV under 5.10 and 5.11. AV
95 and HV were pushed directly onto the pending_array, and not the RV,
96 which caused #33530. So he rewrote the logic to deref the RV inside
97 the array traversal. Applied this with one small omission, which
99 * Fixed 5.11 RV/IV logic. (Thanx Reini Urban!)
100 * Removed one duplicate total_size arrayref test. (Thanx Reini Urban!)
101 * changed //printf to dbg_printf() (Thanx Reini again!)
103 0.70 2008-08-23 Tels 69 tests
104 * fix SEGFAULTS under v5.10 (Thanx Reini Urban!)
105 * fix compilation under blead (Thanx Reini Urban!)
106 * require Perl 5.006 (to stop CPANTESTERS sending bogus reports
107 about failed compiling on ancient Perls)
108 * update the bundles Module::Install to v0.77
110 0.69 2007-08-11 Tels 69 tests
111 * fix compilation under Perl v5.9.5 and v5.10 (Thanx Steve Peters!)
112 * clarify the license by specifying Perl v5.8.8's license
113 * small doc fixes, add a README file
115 0.68 2007-06-12 Tels 69 tests
116 * remove a bit of duplicate code in op_size, the second instance
118 * fix the failing tests by rewriting the test logic to be sane
119 * the count of array slots was off by one
121 0.67 2007-03-15 Tels 20 tests
122 * rip out Build.PL since it doesn't actually work
123 * fix bug #1653: All SVPV subtype may contain an RV instead of a PV
124 (Thanx a lot Jan, and sorry for the truly horrible long delay!)
125 * fix bug #24846: Does not correctly recurse into references in PVNV
127 * add t/recurse.t that tests the two bugfixes in combination
129 0.66 2007-03-02 Tels 15 tests
130 * fix the failing test (the code was right, but the test wrong)
132 0.65 2007-02-24 Tels 15 tests
133 * fix the test failings under 64 bit (bugs #21037, #18596, #21404)
134 * fix wrong size for strings (bug #17586)
135 * reverse Changelog (bug #16636)
136 * Size.xs: remove unused variable "count"
137 * Size.xs: fix warnings about missing ()
138 * Size.xs: fix size of array refs when AvALLOC == 0
140 + maintained by me, signed with my key
141 + bundle Module::Install and use it
143 + rewrite tests to use Test::More; add more tests

150 0.63 Thu Jun 30 14:29:43 2005
151 - Turns out that OP_TRANS is a basic op, not a loop op. This

181 - Fixed a bad size calculation (we were overestimating by one byte)
182 - Updated the docs to show some of the places that there might be 'dark'
183 memory that Devel::Size can't see.
184 - Added in tests from Ken Williams
