1 Revision history for autovivification
3 0.14 2014-11-01 22:25 UTC
4 + Fix : [RT #99458] : AnyEvent::Loop hangs if autovivification 0.13 is
6 [RT #99904] : 'no autovivification' breaks Lingua::EN::Inflect
8 This was a regression in 0.13 which caused the peephole
9 optimizer to loop infinitely on "... while 1" constructs.
10 However, the Lingua::EN::Inflect problem only occured in perl
12 Thanks Toshio Ito and Kent Fredric for reporting.

15 This release contains a change that, while being very likely to be safe,
16 can potentially cause freezes during code compilation. Every release
17 should be carefully tested before being put in production, but this is
18 especially true for this one.
19 + Add : Support for the PERL_OP_PARENT optional feature introduced in
21 + Doc : The CAVEATS section now warns about the global slowdown during
22 compilation caused by this pragma.
23 + Fix : [RT #97703] : Android support
24 t/51-threads-teardown.t will no longer fail on Android.
25 Thanks Brian Fraser for reporting.
26 + Fix : Segfaults in eval in an END block of a Win32 pseudo-fork.
27 + Fix : Segfaults during global destruction of a thread or a
29 + Opt : The global slowdown caused by this module has been greatly
31 Thanks Ævar Arnfjörð Bjarmason for reporting and testing the
34 0.12 2013-09-05 17:20 UTC
35 + Fix : Check functions are now replaced and restored in a thread-safe
36 manner, either by using the wrap_op_checker() function from perl
37 when it is available (starting from perl 5.16) or by taking the
38 OP_REFCNT mutex on older perls.
39 + Tst : Author tests are no longer bundled with this distribution.
40 They are only made available to authors in the git repository.
42 0.11 2013-02-08 19:25 UTC
43 This is a maintenance release. The code contains no functional change.
44 Satisfied users of version 0.10 can skip this update.
45 + Doc : POD tweaks and clarifications.
46 + Tst : Threads tests will not fail anymore if resources constraints
47 prevent the system from creating all the required threads.
48 + Tst : Author tests overhaul.
50 0.10 2011-08-24 15:00 UTC
51 + Fix : The pragma no longer vivifies the "autovivification" entry
52 in the hints hash %^H on perl 5.8.
54 0.09 2011-01-05 18:40 UTC
55 + Fix : [RT #64435] : Hangs with File::Copy in Config.pm.
56 This was actually a regression introduced together with the new
57 peephole optimizer strategy, and that caused the pragma to hang
58 on constructs like "for (;;) { ... }".
59 Thanks Michael Schilli for reporting.
61 0.08 2011-01-03 21:00 UTC
62 + Fix : Building on Windows.
64 0.07 2010-12-31 16:20 UTC
65 + Chg : perl 5.8.3 is required.
66 + Doc : Complements and clarifications.
67 + Fix : Segmentation faults and misbehaviours in threaded applications.
68 + Fix : Compatibility with perl 5.13.7.
69 Thanks Andreas J. König for reporting and Andrew Main for
71 + Fix : Broken linkage on Windows with gcc 3.4, which appears in
72 particular when using ActivePerl's default compiler suite.
73 For those setups, the autovivification shared library will now
74 be linked against the perl dll directly (instead of the import
76 + Opt : The pragma takes slightly more time at compile-time, but is
77 slightly faster at run-time.
78 + Tst : Lengthy tests have been ported to Test::Leaner, making the
79 whole test suite about 50% faster.
80 + Tst : Threads tests are now only run on perl 5.13.4 and higher.
81 They could segfault randomly because of what seems to be an
82 internal bug of Perl, which has been addressed in 5.13.4.
83 There is also an environment variable that allows you to
84 forcefully run those tests, but it should be set only for
85 author testing and not for end users.
87 0.06 2010-04-24 17:40 UTC
88 + Add : The A_THREADSAFE and A_FORKSAFE constants.
89 + Fix : [RT #56870] : "no autovivification" vs Regexp::Common.
90 This was a bug in how tied arrays and hashes were handled.
91 Thanks Michael G. Schwern for reporting.
92 + Fix : Scope leaks under perl 5.8-5.10.0.
93 + Fix : Segfaults when first loading the pragma from inside a thread.
95 0.05 2010-03-05 23:15 UTC
96 + Fix : [RT #55154] : Crashes and assertion failures when deparsing and
97 re-eval-uating some code compiled while autovivification was in
99 Thanks Michael G. Schwern for reporting.
100 + Fix : [RT #53647] : "leys" typo in pod.
101 Thanks Hinrik Orn Sigurdsson for reporting.
103 0.04 2010-01-10 00:30 UTC
104 + Add : Array and hash slices are now handled by the pragma.
105 + Fix : Work around Kwalitee test misfailures.
107 0.03 2009-06-23 22:20 UTC
108 + Add : Handle old-fashion dereferencing (like $$hashref{key}).
109 + Chg : Aliasing constructs (for ($x{foo}) { ... }) are now covered by
110 the 'store' category (and no longer the 'fetch' one). This is
111 because there's no way to know at compile-time if the alias
113 + Fix : Quadratic complexity at compile-time.
114 + Fix : Segfaults when dereferencing globals.
115 + Fix : Segfaults on big-endian systems.
116 + Tst : Really test plain arrays and hashes.
117 + Tst : Improved coverage.
119 0.02 2009-06-17 18:05 UTC
120 + Add : 'fetch' also applies to aliasing ("for ($hashref->{key}) { }").
121 + Fix : Don't segfault on "keys/values %$hashref", and don't vivify if
123 + Fix : Plain dereferencing shouldn't have a different behaviour when
124 the pragma is in use.
125 + Tst : Improved coverage.

128 First version, released on an unsuspecting world.
