This allows the user to attach free magic + (or a plain destructor) to a token returned from the callbacks + in order to defer an action after the magic is processed by + perl. + + Fix : Test failures of threads tests on systems with harsh resource + constraints causing the threads to exit() during run. + +0.57 2015-04-17 15:20 UTC + + Chg : The new environment variable to enable thread tests on older + perls is PERL_FORCE_TEST_THREADS. Note that this variable + should only be turned on by authors. + + Fix : Segfaults when the module is loaded by several threads (or + Windows emulated processes) ran in parallel. + + Fix : Segfaults when the module is loaded in a thread, which spawns + itself a new thread, and that child thread outlives its parent. + + Fix : Small memory leaks of structures required for thread safety. + + Fix : Update the Windows ActivePerl + gcc 3.4 workaround for + ExtUtils::MakeMaker 7.04. Thanks Christian Walde for reporting + and feedback on this issue. + + Tst : The global destruction test will now be exercised on any perl + that has DEBUGGING set. + + Tst : Optional capturing tests in t/17-ctl.t that were only run when + Capture::Tiny was present were converted to an IPC::Open3 + based helper and will now be run everywhere. + +0.56 2015-03-11 15:15 UTC + + Fix : [RT #101410] : Install fails in blead + Even though the change that caused this error was reverted from + blead, lvalue uses of ERRSV have been removed from this module + so that there will be no breakage when this change is possibly + reintroduced in the following months. + Thanks Dave Rolsky for reporting. + + Tst : $ENV{$Config{ldlibpthname}} is now preserved on all platforms, + which will address failures of t/17-ctl.t with unusual + compilers (like icc) that link all their compiled objects to + their own libraries. + + Tst : The global destruction test is now only run on perl 5.13.4 and + higher, and only if either Perl::Destruct::Level is installed + or PERL_DESTRUCT_LEVEL is set and the perl is a debugging perl. + This will solve rare crashes of t/15-self.t on perl 5.13.3 and + older. + +0.55 2014-10-20 23:45 UTC + + Fix : [RT #99319] : t/18-opinfo.t: test failure due to change in + perl 5 blead + The new METHOP op class added in perl 5.21.5 is now supported. + Thanks James E Keenan for reporting. + +0.54 2014-09-22 17:30 UTC + + Add : The new constant VMG_COMPAT_CODE_COPY_CLONE evaluates to true + if your perl calls 'copy' magic when a magical code prototype + is cloned, which is currently the case for perl 5.17.0 and + above. + + Fix : [RT #90205] : copy magic on subs puts raw CV in $_[3] + $_[3] will now contain a reference to the cloned code when + 'copy' magic is called for a coderef. + Thanks Lukas Mai for reporting. + + Fix : t/35-stash.t has been taught about perl 5.21.4. + + Fix : Tests using run_perl() in t/17-ctl.t will no longer fail on + Android. + +0.53 2013-09-01 17:50 UTC + This is a maintenance release. The code contains no functional change. + Satisfied users of version 0.52 can skip this update. + + Fix : [RT #86338] : typo fix. + Thanks dsteinbrunner@pobox.com for the patch. + + Tst : Author tests are no longer bundled with this distribution. + They are only made available to authors in the git repository. + +0.52 2012-11-05 02:30 UTC + + Add : The new constant VMG_COMPAT_SCALAR_NOLEN evaluates to true + when your perl does not call 'len' magic for scalars, which + is the case for perl 5.17.4 and above. + This fixes RT #80388. + + Tst : t/35-stash.t has been taught about perl 5.17.4. + + Tst : Author tests overhaul. + +0.51 2012-08-18 15:00 UTC + + Fix : It is now safe to call dispell() from inside 'free', 'copy' and + 'uvar' callbacks to dispell the magic currently in use. + Thanks Clinton Gormley for reporting. + + Fix : Exceptions thrown from inside a 'free' callback are now always + consistently propagated outside of the callback. They used to + be lost when the 'free' callback was invoked at the end of an + eval block or string. + + Fix : The 'reset RMG flag' workaroundn used to allow wizards with + both 'uvar' and 'clear' magics to be cast onto a hash, has been + made thread-safe. + +0.50 2012-06-24 23:00 UTC + + Fix : Less memory is leaked when a wizard is freed during global + destruction, or when an exception is thrown from a 'free' + callback. + + Fix : [RT #77991] : t/17-ctl.t fails on perl 5.14 and 5.16. + This was actually an issue with ActivePerl, and this test + has learned to cope with it. + Thanks Gisle Aas for reporting. + + Tst : t/35-stash.t has been taught about perl 5.17.1. + + Doc : Many clarifications. + +0.49 2012-06-05 21:40 UTC + This is a maintenance release. The code contains no functional change. + Satisfied users of version 0.48 can skip this update. + + Fix : [RT #77644] : t/17_ctl.t fails in test 44 since 5.17.0. + This test has been taught about perl 5.17.0. + Thanks Reini Urban for reporting. + + Tst : t/99-kwalitee.t will be skipped when only problematic versions + of its dependencies are available. + +0.48 2012-02-17 23:40 UTC + + Add : You can now pass a reference to undef as the magic callback in + order to install a no-op callback. + Thanks Florian Ragwitz for the suggestion. + +0.47 2011-10-27 16:55 UTC + + Add : The new constant VMG_COMPAT_HASH_DELETE_NOUVAR_VOID evaluates + to true when "delete $hash{key}" does not call 'delete' uvar + magic in void context. + + Chg : The MAGIC tokens created by this module no longer use the + mg_private member for storing a "magical" signature. + + Fix : Triggering magic in a thread on a variable cloned from the main + interpreter, and when the wizard already went out of scope, + will not segfault anymore. + + Opt : The pointer table is no longer needed to ensure thread safety. + The size of the object code is about 8% smaller for threaded + perls. + + Tst : Threads tests will not fail anymore if resources constraints + prevent the system from creating all the required threads. + +0.46 2011-01-23 16:45 UTC + + Fix : [RT #64866] : Assertion failure with perl 5.13.9. + The real problem was that dispell() wasn't properly resetting + the magical sv flags, which became visible in the test suite + only with perl 5.13.9. + Thanks Joshua ben Jore for reporting. + +0.45 2010-11-21 23:15 UTC + This is a maintenance release. The code contains no functional change. + Users of 0.44 can skip this update. + + Doc : C++ compilers are officially NOT supported. + + Doc : The minimum perl 5.10.0 requirement for uvar magic has been + made more explicit. + Thanks Peter Rabbitson for pointing this out and contributing a + patch. + + Tst : Tune for perl 5.13.7. + + Tst : Capture::Tiny will be used in t/17-ctl.t if and only if it can + capture a simple run. + +0.44 2010-09-24 19:10 UTC + + Fix : Broken linkage on Windows with gcc 3.4, which appears in + particular when using ActivePerl's default compiler suite. + For those setups, the Variable::Magic shared library will now + be linked against the perl dll directly (instead of the import + library). This (should) fix RT #51483. + Thanks Christian Walde for helping to reproduce this failure + and extra testing. + + Rem : Support for development perls from the 5.11 branch but older + than the 5.11.0 release was removed. This could cause more + recent setups to fail. + + 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. + +0.43 2010-06-25 23:35 UTC + + Add : The new constant VMG_COMPAT_GLOB_GET tells you whether get magic + is called for globs. It's true starting perl 5.13.2. + + Chg : All callbacks are now called within an eval-like context. + Only free callbacks used to be called that way. + + Fix : Some exceptions thrown from a free callback could be lost. + + Fix : Croak messages could sometimes be repeated several times. + + Fix : t/41-clone.t segfaulting with perl 5.13.2. + +0.42 2010-05-19 00:15 UTC + This is a maintenance release. The code contains no functional change. + Users of 0.41 can skip this update. + + Fix : Test failures with perl 5.13. + + Tst : Improve coverage. + +0.41 2010-03-15 17:35 UTC + + Doc : Tweaks and fixups. + Thanks Shlomi Fish. + + Fix : Compatibility with the soon-to-be-released perl 5.12.0. + + Fix : Correctly propagate the errors thrown when variable destruction + happens at compile-time and not from inside eval STRING. + Thanks Florian Ragwitz and Ash Berlin for reporting. + +0.40 2010-01-06 23:20 UTC + + Fix : Possible memory miswrites when passing data arguments to cast(). + + Fix : Minor C portability tweaks. + +0.39 2009-12-01 00:05 UTC + + Add : You can use a function name as a callback by passing a string + reference to wizard() instead of a code reference. + + Fix : Compatiblity with perl 5.11.1 and 5.11.2. + + Fix : Scalars stored into the data slot no longer leak. + + Fix : Thread destruction should not segfault anymore. + + Opt : As a result of removing the deprecated features, less memory is + used for both threaded (a pointer table is used instead of a + hash) and non-threaded (no global structure is needed anymore) + perls. + + Rem : As advertised in the precendent version, all the signature + related features were removed. This includes the 'sig' option + to wizard(), the getsig() and gensig() functions, and the SIG_* + constants. + +0.38 2009-10-04 16:10 UTC + + Dep : All the signature-related features are DEPRECATED and will be + removed in december 2009. This includes the 'sig' option to + wizard(), the getsig() and gensig() functions, and the SIG_* + constants. + Afaik those features were never used in real life, and they make + the XS code slow and brittle. If you want your wizards to be + globally available, you'll have to handle that yourself by + storing them in a hash. + + Doc : More examples in a new COOKBOOK section. + + Fix : Compatiblity with the 5.11.0 release. The new compatibility + constant VMG_COMPAT_ARRAY_PUSH_NOLEN_VOID was added to cover + this. + + Fix : Work around Kwalitee test misfailures. + +0.37 2009-08-25 15:25 UTC + + Add : The new constant VMG_FORKSAFE can be tested to know whether the + module will behave nicely when fork()ing. It's currently always + true except on Windows where you need perl 5.10.1 for it to be + true. + + Doc : Nits and clarifications. + +0.36 2009-07-05 16:30 UTC + + Chg : getdata() now returns an empty list when no magic is present. + It used to return undef but did not croak as stated in the doc. + Thanks Matt S. Trout for pointing this out. + + Fix : Building and tests with ActiveState Perl 5.8 build >= 822. + +0.35 2009-05-15 20:50 UTC + This is a maintenance release. Users of 0.34 can skip this update. + + Chg : uvar magic used to be enabled for 5.9.5. It now requires 5.10 or + later. + + Fix : Silence compilation warnings for cxinc(). + + Rem : The workaround introduced in 0.31 for the "Unknown errors" issue + was removed, as regression tests show that 0.34 provides a + better fix. + + Tst : Skip t/40-threads.t on 5.8.x with old versions of threads and + threads::shared. + +0.34 2009-04-19 16:55 UTC + + Fix : Destruction of wizards in require. + + Fix : "panic: restartop" in 5.10 when dieing at compile time triggers + a destructor. + +0.33 2009-03-26 00:00 UTC + + Chg : cast() and getsig() now croak too when an invalid signature is + passed. + + Fix : It was possible to generate with gensig() the same signature + twice before actually defining the wizards. + + Tst : More stash tests. + + Tst : Test when the magic takes place in some cases. + + Tst : Improved coverage for the op object feature. + +0.32 2009-03-01 13:45 UTC + + Chg : dispell() and getdata() now croak when an invalid signature is + passed. + + Doc : More examples and a brand new synopsis. + + Fix : The signature is no longer stored in the mg_private member of + the MAGIC struct. This fixes possible clashes with magics from + other extensions. + + Fix : op info objects weren't blessed into the right class. + + Fix : Races when initializing the op names cache under threads. + 0.31 2009-02-19 23:50 UTC + Doc : A somewhat better introduction. The FUNCTION section was moved before CONSTANTS and HISTORY since it's more important. And
