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]
6 * skip tests in t/magic.t that use formline on 5.8.1 and 5.8.2, as those
7 versions have a buggy formline that can trigger an assertion failure.
9 0.77 2011-05-16 nicholas
12 0.76_50 2011-05-12 nicholas
13 * Split out HEK size calculation into hek_size(). Add the shared HE overhead.
14 * Handle shared hash key scalars correctly.
15 * GvNAME() is shared from 5.10 onwards.
16 * Count HvNAME(), the HV "aux" struct, the mro_meta struct, and ENAMEs.
18 0.76 2011-05-11 nicholas
19 * Just fix the version number in the line below.
21 0.75_52 2011-05-09 nicholas
22 * Use a table for SV body sizes. These incorporate the space saving post 5.8.x
23 * Correctly handle SvOOK scalars. 5.12 and later don't use SvIVX().
24 * Magic vtables aren't freed when magic is freed, so don't count them.
25 (They are static structures. Anything that assumes otherwise is buggy.)
26 * Reinstate 5.6.x "support". (i.e. it compiles and passes tests.)
27 * Reinstate 5.005_xx "support". (i.e. it compiles and passes tests.)
29 0.75_51 2011-05-05 nicholas
30 * Only use a static array of vtables on gcc.
32 0.75_50 2011-05-04 nicholas
33 * The core's magic vtables are global constants, so aren't part of the size.
34 * Follow mg_obj and mg_ptr.
36 0.75 2011-05-04 nicholas
39 0.74_53 2011-05-01 nicholas
40 * Fix typo error in bit-vector tracking mechanism. On 64 bit platforms which
41 allocate on 8 byte alignment (rather than 16), a low pointer bit could get
42 lost, resulting in new pointers being considered already "seen".
43 "Found" by BinGOs' smoker, fixed on spectre.mongueurs.net. Thanks.
45 0.74_52 2011-04-23 nicholas
46 * Fix potential SEGVs for OP_AELEMFAST on a lexical (eg $foo[3])
47 * Fix likely SEGVs for PVOPs (missing break)
48 * Fix potential SEGVs for PVBMs on 5.10 and later
49 * Move hash and array traversal from total_size() to sv_size()
50 - this allows total_size() and size() to be XS ALIASes.
52 0.74_51 2011-04-22 nicholas
53 * Don't count PL_sv_{undef,no,yes} in the size returned
54 * total_size() was double-counting entries in typeglobs
55 * sv_size() was double-counting the PVGV size if GvEGV() looped back
56 * fix classic off-by-one error - the answer is strlen() + 1, not just strlen()
58 0.74_50 2011-04-19 nicholas
59 * Ensure that size() doesn't add the referent's size for non SVt_RV references
61 0.74 2011-04-19 nicholas
62 * Correct the Makefile.PL - LICENSE was added to ExtUtils::MakeMaker in 6.31
64 0.73_51 2011-04-17 nicholas
65 * Refactor the C code to accumulate the size inside the tracking structure
66 - this means that the C *_size() functions now return void
67 - The XS functions size() and total_size() now return UV, not IV
69 0.73_50 2011-04-17 nicholas
70 * Avoid using assert() on ithreaded 5.8.8 and earlier, as it needs my_perl
71 * Fix the test added in 0.73, as it tripped over a combination of bugs
73 0.73 2011-04-16 nicholas
74 * Revert a bad assertion introduced in 0.72_50, which was logically wrong.
75 - and a test to demonstrate one case that would trigger it
77 0.72_52 2011-04-15 nicholas
78 * Add a test for the non-exceptional warnings.
80 0.72_51 2011-04-15 nicholas
81 * Add PERL_NO_GET_CONTEXT to improve performance under multiplicity
83 0.72_50 2011-04-14 nicholas
84 * Exception handling is totally MSVC specific, so only use it there
85 - this means that we don't need to use a C++ compiler anywhere
86 * Rework bit-vector tracking mechanism to use a 256-way tree. This avoids
87 making assumptions about 64-bit platforms' memory layouts, and eliminates
88 the fatal error introduced in 0.72 when the assumption was violated.
90 * Resolve CPAN #49437 (Devel::Size adds magic in Perl 5.10)
91 * Resolve CPAN #58484 and #58485 (related to CVs that are XSUBs)
93 0.72 2008-10-14 BrowserUk 70 tests
94 * Added bit-vector pointer tracking mechanism.
95 - new fatal error (64-bit platforms only)
96 * Added exception handling
97 - 4 new warnings (disabled by default)
98 * Updated POD to reflect above
99 * Added basic.t test 13
100 * replaced Module::Install with hand crafted EU::MM Makefile.pl
101 (With many thanks to Sisyphus)
102 because we couldn't work out how to add C++ options to allow
105 0.71 2008-08-24 Tels 69 tests
106 * adapt patch from Reini Urban to fix failing RV under 5.10 and 5.11. AV
107 and HV were pushed directly onto the pending_array, and not the RV,
108 which caused #33530. So he rewrote the logic to deref the RV inside
109 the array traversal. Applied this with one small omission, which
111 * Fixed 5.11 RV/IV logic. (Thanx Reini Urban!)
112 * Removed one duplicate total_size arrayref test. (Thanx Reini Urban!)
113 * changed //printf to dbg_printf() (Thanx Reini again!)
115 0.70 2008-08-23 Tels 69 tests
116 * fix SEGFAULTS under v5.10 (Thanx Reini Urban!)
117 * fix compilation under blead (Thanx Reini Urban!)
118 * require Perl 5.006 (to stop CPANTESTERS sending bogus reports
119 about failed compiling on ancient Perls)
120 * update the bundles Module::Install to v0.77
122 0.69 2007-08-11 Tels 69 tests
123 * fix compilation under Perl v5.9.5 and v5.10 (Thanx Steve Peters!)
124 * clarify the license by specifying Perl v5.8.8's license
125 * small doc fixes, add a README file
127 0.68 2007-06-12 Tels 69 tests
128 * remove a bit of duplicate code in op_size, the second instance
130 * fix the failing tests by rewriting the test logic to be sane
131 * the count of array slots was off by one
133 0.67 2007-03-15 Tels 20 tests
134 * rip out Build.PL since it doesn't actually work
135 * fix bug #1653: All SVPV subtype may contain an RV instead of a PV
136 (Thanx a lot Jan, and sorry for the truly horrible long delay!)
137 * fix bug #24846: Does not correctly recurse into references in PVNV
139 * add t/recurse.t that tests the two bugfixes in combination
141 0.66 2007-03-02 Tels 15 tests
142 * fix the failing test (the code was right, but the test wrong)
144 0.65 2007-02-24 Tels 15 tests
145 * fix the test failings under 64 bit (bugs #21037, #18596, #21404)
146 * fix wrong size for strings (bug #17586)
147 * reverse Changelog (bug #16636)
148 * Size.xs: remove unused variable "count"
149 * Size.xs: fix warnings about missing ()
150 * Size.xs: fix size of array refs when AvALLOC == 0
152 + maintained by me, signed with my key
153 + bundle Module::Install and use it
155 + rewrite tests to use Test::More; add more tests
