1 Revision history for autovivification
3 0.18 2017-11-04 15:30 UTC
4 + Fix : [RT #123411] : Compatibility with CV-in-stash optimisation
5 Thanks Father Chrysostomos for reporting and contributing a
7 + Fix : [RT #122956] : strict/warn flags seem to simply do nothing
8 The documentation has been amended to clarify how these two
9 options are supposed to be used.
10 Thanks Christian Walde for reporting.

13 + Chg : A large chunk of boilerplate XS code, which is also used in
14 other XS modules, has been factored out of the main .xs file
15 to a collection of .h files in the xsh subdirectory.
16 + Fix : The new optimization in perl 5.27.3 for scalar(keys(%$hashref))
17 is now correcty supported.
19 0.16 2015-07-01 14:30 UTC
20 + Fix : Broken linkage on Windows.
22 0.15 2015-05-14 20:35 UTC
23 + Chg : The new environment variable to enable thread tests on older
24 perls is PERL_FORCE_TEST_THREADS. Note that this variable
25 should only be turned on by authors.
26 + Fix : The module has been taught about the new multideref
27 optimization, and will function properly on perl 5.21.11 and
29 + Fix : The module will no longer crash or behave erratically when it
30 is loaded by several threads (or Windows emulated processes)
32 + Fix : Update the Windows ActivePerl + gcc 3.4 workaround for
33 ExtUtils::MakeMaker 7.04. Thanks Christian Walde for reporting
34 and feedback on this issue.
35 + Fix : Be really compatible with the optional OP_PARENT feature.
36 + Tst : $ENV{$Config{ldlibpthname}} is now preserved on all platforms,
37 which will address failures of t/43-peep.t and
38 t/51-threads-teardown.t with unusual compilers (like icc) that
39 link all their compiled objects to their own libraries.
41 0.14 2014-11-01 22:25 UTC
42 + Fix : [RT #99458] : AnyEvent::Loop hangs if autovivification 0.13 is
44 [RT #99904] : 'no autovivification' breaks Lingua::EN::Inflect
46 This was a regression in 0.13 which caused the peephole
47 optimizer to loop infinitely on "... while 1" constructs.
48 However, the Lingua::EN::Inflect problem only occured in perl
50 Thanks Toshio Ito and Kent Fredric for reporting.
52 0.13 2014-10-04 16:55 UTC
53 This release contains a change that, while being very likely to be safe,
54 can potentially cause freezes during code compilation. Every release
55 should be carefully tested before being put in production, but this is
56 especially true for this one.
57 + Add : Support for the PERL_OP_PARENT optional feature introduced in
59 + Doc : The CAVEATS section now warns about the global slowdown during
60 compilation caused by this pragma.
61 + Fix : [RT #97703] : Android support
62 t/51-threads-teardown.t will no longer fail on Android.
63 Thanks Brian Fraser for reporting.
64 + Fix : Segfaults in eval in an END block of a Win32 pseudo-fork.
65 + Fix : Segfaults during global destruction of a thread or a
67 + Opt : The global slowdown caused by this module has been greatly
69 Thanks Ævar Arnfjörð Bjarmason for reporting and testing the
72 0.12 2013-09-05 17:20 UTC
73 + Fix : Check functions are now replaced and restored in a thread-safe
74 manner, either by using the wrap_op_checker() function from perl
75 when it is available (starting from perl 5.16) or by taking the
76 OP_REFCNT mutex on older perls.
77 + Tst : Author tests are no longer bundled with this distribution.
78 They are only made available to authors in the git repository.
80 0.11 2013-02-08 19:25 UTC
81 This is a maintenance release. The code contains no functional change.
82 Satisfied users of version 0.10 can skip this update.
83 + Doc : POD tweaks and clarifications.
84 + Tst : Threads tests will not fail anymore if resources constraints
85 prevent the system from creating all the required threads.
86 + Tst : Author tests overhaul.
88 0.10 2011-08-24 15:00 UTC
89 + Fix : The pragma no longer vivifies the "autovivification" entry
90 in the hints hash %^H on perl 5.8.
92 0.09 2011-01-05 18:40 UTC
93 + Fix : [RT #64435] : Hangs with File::Copy in Config.pm.
94 This was actually a regression introduced together with the new
95 peephole optimizer strategy, and that caused the pragma to hang
96 on constructs like "for (;;) { ... }".
97 Thanks Michael Schilli for reporting.
99 0.08 2011-01-03 21:00 UTC
100 + Fix : Building on Windows.
102 0.07 2010-12-31 16:20 UTC
103 + Chg : perl 5.8.3 is required.
104 + Doc : Complements and clarifications.
105 + Fix : Segmentation faults and misbehaviours in threaded applications.
106 + Fix : Compatibility with perl 5.13.7.
107 Thanks Andreas J. König for reporting and Andrew Main for
109 + Fix : Broken linkage on Windows with gcc 3.4, which appears in
110 particular when using ActivePerl's default compiler suite.
111 For those setups, the autovivification shared library will now
112 be linked against the perl dll directly (instead of the import
114 + Opt : The pragma takes slightly more time at compile-time, but is
115 slightly faster at run-time.
116 + Tst : Lengthy tests have been ported to Test::Leaner, making the
117 whole test suite about 50% faster.
118 + Tst : Threads tests are now only run on perl 5.13.4 and higher.
119 They could segfault randomly because of what seems to be an
120 internal bug of Perl, which has been addressed in 5.13.4.
121 There is also an environment variable that allows you to
122 forcefully run those tests, but it should be set only for
123 author testing and not for end users.
125 0.06 2010-04-24 17:40 UTC
126 + Add : The A_THREADSAFE and A_FORKSAFE constants.
127 + Fix : [RT #56870] : "no autovivification" vs Regexp::Common.
128 This was a bug in how tied arrays and hashes were handled.
129 Thanks Michael G. Schwern for reporting.
130 + Fix : Scope leaks under perl 5.8-5.10.0.
131 + Fix : Segfaults when first loading the pragma from inside a thread.
133 0.05 2010-03-05 23:15 UTC
134 + Fix : [RT #55154] : Crashes and assertion failures when deparsing and
135 re-eval-uating some code compiled while autovivification was in
137 Thanks Michael G. Schwern for reporting.
138 + Fix : [RT #53647] : "leys" typo in pod.
139 Thanks Hinrik Orn Sigurdsson for reporting.
141 0.04 2010-01-10 00:30 UTC
142 + Add : Array and hash slices are now handled by the pragma.
143 + Fix : Work around Kwalitee test misfailures.
145 0.03 2009-06-23 22:20 UTC
146 + Add : Handle old-fashion dereferencing (like $$hashref{key}).
147 + Chg : Aliasing constructs (for ($x{foo}) { ... }) are now covered by
148 the 'store' category (and no longer the 'fetch' one). This is
149 because there's no way to know at compile-time if the alias
151 + Fix : Quadratic complexity at compile-time.
152 + Fix : Segfaults when dereferencing globals.
153 + Fix : Segfaults on big-endian systems.
154 + Tst : Really test plain arrays and hashes.
155 + Tst : Improved coverage.
157 0.02 2009-06-17 18:05 UTC
158 + Add : 'fetch' also applies to aliasing ("for ($hashref->{key}) { }").
159 + Fix : Don't segfault on "keys/values %$hashref", and don't vivify if
161 + Fix : Plain dereferencing shouldn't have a different behaviour when
162 the pragma is in use.
163 + Tst : Improved coverage.

166 First version, released on an unsuspecting world.
