Revision history for autovivification
+0.12 2013-09-05 17:20 UTC
+ + Fix : Check functions are now replaced and restored in a thread-safe
+ manner, either by using the wrap_op_checker() function from perl
+ when it is available (starting from perl 5.16) or by taking the
+ OP_REFCNT mutex on older perls.
+ + Tst : Author tests are no longer bundled with this distribution.
+ They are only made available to authors in the git repository.
+
+0.11 2013-02-08 19:25 UTC
+ This is a maintenance release. The code contains no functional change.
+ Satisfied users of version 0.10 can skip this update.
+ + Doc : POD tweaks and clarifications.
+ + Tst : Threads tests will not fail anymore if resources constraints
+ prevent the system from creating all the required threads.
+ + Tst : Author tests overhaul.
+
+0.10 2011-08-24 15:00 UTC
+ + Fix : The pragma no longer vivifies the "autovivification" entry
+ in the hints hash %^H on perl 5.8.
+
+0.09 2011-01-05 18:40 UTC
+ + Fix : [RT #64435] : Hangs with File::Copy in Config.pm.
+ This was actually a regression introduced together with the new
+ peephole optimizer strategy, and that caused the pragma to hang
+ on constructs like "for (;;) { ... }".
+ Thanks Michael Schilli for reporting.
+
+0.08 2011-01-03 21:00 UTC
+ + Fix : Building on Windows.
+
+0.07 2010-12-31 16:20 UTC
+ + Chg : perl 5.8.3 is required.
+ + Doc : Complements and clarifications.
+ + Fix : Segmentation faults and misbehaviours in threaded applications.
+ + Fix : Compatibility with perl 5.13.7.
+ Thanks Andreas J. König for reporting and Andrew Main for
+ providing a fix.
+ + Fix : Broken linkage on Windows with gcc 3.4, which appears in
+ particular when using ActivePerl's default compiler suite.
+ For those setups, the autovivification shared library will now
+ be linked against the perl dll directly (instead of the import
+ library).
+ + Opt : The pragma takes slightly more time at compile-time, but is
+ slightly faster at run-time.
+ + Tst : Lengthy tests have been ported to Test::Leaner, making the
+ whole test suite about 50% faster.
+ + Tst : Threads tests are now only run on perl 5.13.4 and higher.
+ They could segfault randomly because of what seems to be an
+ internal bug of Perl, which has been addressed in 5.13.4.
+ There is also an environment variable that allows you to
+ forcefully run those tests, but it should be set only for
+ author testing and not for end users.
+
+0.06 2010-04-24 17:40 UTC
+ + Add : The A_THREADSAFE and A_FORKSAFE constants.
+ + Fix : [RT #56870] : "no autovivification" vs Regexp::Common.
+ This was a bug in how tied arrays and hashes were handled.
+ Thanks Michael G. Schwern for reporting.
+ + Fix : Scope leaks under perl 5.8-5.10.0.
+ + Fix : Segfaults when first loading the pragma from inside a thread.
