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.
7 0.76 2011-05-11 nicholas
8 * Just fix the version number in the line below.
10 0.75_52 2011-05-09 nicholas
11 * Use a table for SV body sizes. These incorporate the space saving post 5.8.x
12 * Correctly handle SvOOK scalars. 5.12 and later don't use SvIVX().
13 * Magic vtables aren't freed when magic is freed, so don't count them.
14 (They are static structures. Anything that assumes otherwise is buggy.)
15 * Reinstate 5.6.x "support". (i.e. it compiles and passes tests.)
16 * Reinstate 5.005_xx "support". (i.e. it compiles and passes tests.)
18 0.75_51 2011-05-05 nicholas
19 * Only use a static array of vtables on gcc.
21 0.75_50 2011-05-04 nicholas
22 * The core's magic vtables are global constants, so aren't part of the size.
23 * Follow mg_obj and mg_ptr.
25 0.75 2011-05-04 nicholas
28 0.74_53 2011-05-01 nicholas
29 * Fix typo error in bit-vector tracking mechanism. On 64 bit platforms which
30 allocate on 8 byte alignment (rather than 16), a low pointer bit could get
31 lost, resulting in new pointers being considered already "seen".
32 "Found" by BinGOs' smoker, fixed on spectre.mongueurs.net. Thanks.
34 0.74_52 2011-04-23 nicholas
35 * Fix potential SEGVs for OP_AELEMFAST on a lexical (eg $foo[3])
36 * Fix likely SEGVs for PVOPs (missing break)
37 * Fix potential SEGVs for PVBMs on 5.10 and later
38 * Move hash and array traversal from total_size() to sv_size()
39 - this allows total_size() and size() to be XS ALIASes.
41 0.74_51 2011-04-22 nicholas
42 * Don't count PL_sv_{undef,no,yes} in the size returned
43 * total_size() was double-counting entries in typeglobs
44 * sv_size() was double-counting the PVGV size if GvEGV() looped back
45 * fix classic off-by-one error - the answer is strlen() + 1, not just strlen()
47 0.74_50 2011-04-19 nicholas
48 * Ensure that size() doesn't add the referent's size for non SVt_RV references
50 0.74 2011-04-19 nicholas
51 * Correct the Makefile.PL - LICENSE was added to ExtUtils::MakeMaker in 6.31
53 0.73_51 2011-04-17 nicholas
54 * Refactor the C code to accumulate the size inside the tracking structure
55 - this means that the C *_size() functions now return void
56 - The XS functions size() and total_size() now return UV, not IV
58 0.73_50 2011-04-17 nicholas
59 * Avoid using assert() on ithreaded 5.8.8 and earlier, as it needs my_perl
60 * Fix the test added in 0.73, as it tripped over a combination of bugs
62 0.73 2011-04-16 nicholas
63 * Revert a bad assertion introduced in 0.72_50, which was logically wrong.
64 - and a test to demonstrate one case that would trigger it
66 0.72_52 2011-04-15 nicholas
67 * Add a test for the non-exceptional warnings.
69 0.72_51 2011-04-15 nicholas
70 * Add PERL_NO_GET_CONTEXT to improve performance under multiplicity
72 0.72_50 2011-04-14 nicholas
73 * Exception handling is totally MSVC specific, so only use it there
74 - this means that we don't need to use a C++ compiler anywhere
75 * Rework bit-vector tracking mechanism to use a 256-way tree. This avoids
76 making assumptions about 64-bit platforms' memory layouts, and eliminates
77 the fatal error introduced in 0.72 when the assumption was violated.
79 * Resolve CPAN #49437 (Devel::Size adds magic in Perl 5.10)
80 * Resolve CPAN #58484 and #58485 (related to CVs that are XSUBs)
82 0.72 2008-10-14 BrowserUk 70 tests
83 * Added bit-vector pointer tracking mechanism.
84 - new fatal error (64-bit platforms only)
85 * Added exception handling
86 - 4 new warnings (disabled by default)
87 * Updated POD to reflect above
88 * Added basic.t test 13
89 * replaced Module::Install with hand crafted EU::MM Makefile.pl
90 (With many thanks to Sisyphus)
91 because we couldn't work out how to add C++ options to allow
94 0.71 2008-08-24 Tels 69 tests
95 * adapt patch from Reini Urban to fix failing RV under 5.10 and 5.11. AV
96 and HV were pushed directly onto the pending_array, and not the RV,
97 which caused #33530. So he rewrote the logic to deref the RV inside
98 the array traversal. Applied this with one small omission, which
100 * Fixed 5.11 RV/IV logic. (Thanx Reini Urban!)
101 * Removed one duplicate total_size arrayref test. (Thanx Reini Urban!)
102 * changed //printf to dbg_printf() (Thanx Reini again!)
104 0.70 2008-08-23 Tels 69 tests
105 * fix SEGFAULTS under v5.10 (Thanx Reini Urban!)
106 * fix compilation under blead (Thanx Reini Urban!)
107 * require Perl 5.006 (to stop CPANTESTERS sending bogus reports
108 about failed compiling on ancient Perls)
109 * update the bundles Module::Install to v0.77
111 0.69 2007-08-11 Tels 69 tests
112 * fix compilation under Perl v5.9.5 and v5.10 (Thanx Steve Peters!)
113 * clarify the license by specifying Perl v5.8.8's license
114 * small doc fixes, add a README file
116 0.68 2007-06-12 Tels 69 tests
117 * remove a bit of duplicate code in op_size, the second instance
119 * fix the failing tests by rewriting the test logic to be sane
120 * the count of array slots was off by one
122 0.67 2007-03-15 Tels 20 tests
123 * rip out Build.PL since it doesn't actually work
124 * fix bug #1653: All SVPV subtype may contain an RV instead of a PV
125 (Thanx a lot Jan, and sorry for the truly horrible long delay!)
126 * fix bug #24846: Does not correctly recurse into references in PVNV
128 * add t/recurse.t that tests the two bugfixes in combination
130 0.66 2007-03-02 Tels 15 tests
131 * fix the failing test (the code was right, but the test wrong)
133 0.65 2007-02-24 Tels 15 tests
134 * fix the test failings under 64 bit (bugs #21037, #18596, #21404)
135 * fix wrong size for strings (bug #17586)
136 * reverse Changelog (bug #16636)
137 * Size.xs: remove unused variable "count"
138 * Size.xs: fix warnings about missing ()
139 * Size.xs: fix size of array refs when AvALLOC == 0
141 + maintained by me, signed with my key
142 + bundle Module::Install and use it
144 + rewrite tests to use Test::More; add more tests

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