Revision history for Variable-Magic
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
'assignation' is really 'assignment', says Ricardo. :)
+ Fix : The op_info features are now thread safe.
+ Fix : Segfaults that occured when trying to get the op name during
global destruction.
+ Fix : Segfaults and wrong "Unknown error" exceptions that happened
when dieing in require caused a free callback to fire.
Thanks Florian Ragwitz for reporting.
0.30 2009-02-12 17:05 UTC
+ Add : You can now get in all the callbacks either the name or a B::OP
object representing the current op if you pass the new 'op_info'
option to wizard() with respective values VMG_OP_INFO_NAME and
VMG_OP_INFO_OBJECT.
+ Doc : Document magic on array/hashes values.
+ Fix : Completely skip free callbacks during global destruction.
+ Tst : Tests now pass again on 5.8.3 and lower (they were broken since
0.27).
+ Tst : Test magic on symbol table and on array/hash values.
0.29 2009-02-08 11:10 UTC
+ Add : Set $_[2] to the default length for len magic on scalars.
+ Chg : Perl 5.8 is required.
+ Chg : The CLONE method will no longer be defined for non-threaded
perls.
+ Doc : Nits.
+ Fix : The logic for turning off the GMAGICAL flag on hashes when no
uvar magic is involved could do nasty things on tied hashes.
+ Upd : More resources in META.yml.
0.28 2009-01-24 17:05 UTC
+ Add : The 'copy_key' option to wizard(), that enables the safe edition
of $_[2] in uvar callbacks to redirect actions to another key.
+ Fix : Exception objects thrown from callbacks at compile time were not
available in $@.
+ Fix : free callbacks triggered during global destruction could lead to
segfaults because the wizard was already freed.
+ Fix : Refcount of scalars with free callback.
+ Fix : Segfaults when using get or uvar magic simultaneously with clear
magic.
+ Doc : The documentation about what the callbacks take and should
return is now somewhat clearer.
0.27 2009-01-18 23:40 UTC
+ Fix : Offset of 1 with len magic on scalars.
+ Fix : Segfaults that seem to happen when one croak in a callback at
compile time (thanks Ash Berlin for the testcase).
+ Upd : Resources in META.yml (Florian Ragwitz)
+ Tst : Large cleanup resulting in a wider set of tested behaviours.
0.26 2008-11-29 22:05 UTC
+ Fix : Leaks of cloned coderefs that access lexicals.
+ Fix : Building with maint-5.8 and blead (thanks Andreas Koenig).
0.25 2008-11-12 19:40 UTC
+ Fix : Compatibility with 5.8.9.
+ Fix : Old Pod::Coverage don't ignore CLONE.
+ Upd : META.yml spec updated to 1.4.
0.24 2008-10-12 14:55 UTC
+ Fix : Really fix it.
0.23 2008-10-11 17:25 UTC
+ Fix : Building on perls with multiplicity but not ithreads.
0.22 2008-09-29 19:40 UTC
+ Doc : Explain how magic differs from overloading.
+ Fix : Disable thread safety for perl 5.8 on Windows. If you want it
enabled, reliable feedback is welcome.
0.21_02 2008-09-28 23:10 UTC
+ Fix : Hide previously deleted magic tokens in vmg_svt_free (Yuval
Kogman).
0.21_01 2008-09-22 13:25 UTC
+ Chg : Shrink the context data.
+ Fix : Enable thread safety features for perls that just lack
MY_CXT_CLONE.
+ Tst : Output threads and threads::shared versions in threads tests.
0.20 2008-09-20 23:35 UTC
+ Fix : The module is now thread safe. You can test if it had been
built with thread safety features enabled through the
VMG_THREADSAFE constant.
+ Fix : Correct backtrace when wizard() croaks.
+ Fix : 'cast $a, undef' should throw an 'invalid wizard' error instead
of an 'invalid signature'.
0.19 2008-07-05 15:05 UTC
+ Add : The patchlevel with which the module has been built is now
exported with the VMG_PERL_PATCHLEVEL constant.
+ Chg : Version checking macros overhaul.
+ Fix : 'uvar' magic should only be enabled in maint-5.10 and higher
since it's never going to be backported to 5.8.
+ Fix : Likewise, the copy callback API change should only be enabled in
5.11 and higher.
+ Fix : Instead of those ackward fake refcount increments in the wizard
destructor, flag the wizard with SVf_BREAK and force temps
cleanup. This should fix the wizard destruction for all perls,
and solves the leak introduced by the previous solution.
0.18 2008-07-04 12:20 UTC
+ Fix : Enable uvar magic when patchlevel >= 28419.
+ Fix : Set VMG_COMPAT_ARRAY_PUSH_NOLEN for Windows ActiveState Perl
5.8.x.
0.17 2008-05-11 09:05 UTC
+ Fix : 5.8.4 and lower don't have mPUSHi. Gah. Yeah, I know, I should
use Devel::PPPort.
0.16 2008-05-10 22:05 UTC
+ Add : The samples/copy.pl script.
+ Chg : The sv_magical() + vmg_mg_magical() combo was simplified into
vmg_sv_magicuvar().
+ Tst : t/33-code.t was testing scalars, not code.
+ Tst : is() and like() are better than ok().
+ Tst : 100% coverage reached.
0.15 2008-04-11 18:25 UTC
+ Chg : Factor vmg_cb_call{1,2,3}() into one function.
+ Fix : len magic is no longer called when taking the length() of a
magical scalar since p32969. The VMG_COMPAT_SCALAR_LENGTH_NOLEN
constant was added to cover this.
+ Tst : More tests for t/22-len.t.
0.14 2008-03-24 12:35 UTC
+ Fix : t/16-huf.t failures on Solaris and FreeBSD caused by not
updating mg->mg_ptr after Renew-ing it on dispell.
+ Fix : Undefining MGf_DUP caused the wizard's magic to be wrongly
initialized. MGf_DUP now appears as true from the user point of
view, but the dup callback isn't actually set.
+ Fix : Warnings with blead due to copy callbacks now taking an I32 (API
change #33256).
+ Fix : vmg_svt_val() and vmg_uvar_del() aren't required if no uvar
magic is available.
+ Tst : Tests now output the version of optional modules loaded.
0.13 2008-03-19 14:35 UTC
+ Doc : Link to coverage report.
+ Fix : Correct dependencies listing in META.yml.
+ Tst : Improved test coverage.
+ Tst : Print the patchlevel as a comment.
+ Tst : Use is() where it's relevant.
+ Tst : t/16-huf.t now really tests interaction with H::U::FH.
0.12 2008-02-07 18:15 UTC
+ Fix : POD error. Thanks to Chris Williams (BinGOs) for the quick
feedback.
0.11 2008-02-07 17:55 UTC
+ Add : Copy callbacks now receive the current key/index in $_[2].
The current value/element is now in $_[3].
+ Chg : The trigger of copy magic on list assignment with perls greater
than 5.10.0 was caused by uvar magic. Hence,
VMG_COMPAT_HASH_LISTASSIGN_COPY was removed. Use VMG_UVAR
instead.
+ Fix : Build failures on patched perls.
+ Tst : Added missing exported symbols to 01-import.t.
0.10 2008-02-04 11:30 UTC
+ Add : New script : samples/vm_vs_tie.pl, that benchmarks our uvar
magic versus tied hashes.
+ Add : The VMG_COMPAT_* constants can be used from userspace to check
perl magic abilities.
+ Fix : Callbacks that returned undef made us croak, breaking the
variable behaviour (regression test in 14-callbacks.t).
+ Fix : uvar callbacks weren't tested for non-NULL-ity before being
called (regression test in 28-uvar.t).
+ Tst : Fix typo in 25-copy.t that prevented Tie::Hash tests to be ran.
0.09 2008-02-02 11:30 UTC
+ Doc : Explicitely say that uvar callbacks are safely ignored for
non-hashes.
+ Doc : Document caveats and fix the usual set of typos.
+ Fix : vmg_dispell() didn't check if the ext magic were ours when
counting wizards that have uvar callbacks, resulting in a
possible memory misread.
+ Fix : getdata() now returns directly the data object, and no longer a
copy. This caused a leak.
+ Tst : Prefix author tests by 9*-.
+ Tst : New optional author test : 95-portability-files.t, that uses
Test::Portability::Files when it's present.
+ Tst : New test : 14-self.t, that tests application of magic on the
wizard itself.
+ Tst : Move Hash::Util::FieldHash tests out of 11-multiple.t to
15-huf.t.
0.08 2008-02-01 16:55 UTC
+ Add : copy magic for tied arrays/hashes.
+ Add : local magic.
+ Add : uvar magics : fetch, store, exists, delete for hashes.
0.07_* 2008-01
Internal development versions.
0.06 2007-11-20 10:10 UTC
+ Chg : 5.7.3 is now officially required.
+ Fix : "data" test failures on 5.8.{0,2}.
+ Fix : Drand01() vs rand().
0.05 2007-11-19 09:10 UTC
+ Fix : 5.10.0_RC1 compatibility fix.
0.04 2007-08-28 12:25 UTC
+ Chg : s/require (XSLoader)/use $1/.
+ Fix : Tests are now strict.
+ Fix : Complete dependencies.
0.03 2007-08-01 17:20 UTC
+ Add : Passing the signature of an already defined magic to wizard()
now returns the corresponding magic object.
+ Add : You can pass the numeric signature as the wizard argument of
cast(), dispell() and getdata().
+ Add : Any argument specified after the wizard (or the signature) in a
call to cast() is now passed to the private data constructor in
$_[1] and after.
+ Chg : $_[0] is now always a reference to the magic variable in all
callbacks. The reason for changing from the previous behaviour
is that one may want to apply the same magic to a plain scalar
and to a scalar reference, and needs a way to distinguish
between them in the callback (say, ref()).
+ Fix : Wizard object destruction used not to free the signature.
0.02 2007-07-27 13:50 UTC
+ Fix : In response to test report 548152 :
Newx() and SvMAGIC_set() not present on older perls.
+ Fix : In response to test report 548275 :
Since perl 5.9.5, 'clear' magic is invoked when an array is
undefined (bug #43357). Moreover, 'len' magic is no longer
called by pushing an element since perl 5.9.3.
+ Fix : Missing glob test in MANIFEST.
0.01 2007-07-25 16:15 UTC
First version, released on an unsuspecting world.
