1 Revision history for Variable-Magic
3 0.63 2022-09-20 21:45 UTC
4 This is a maintenance release. The code contains no functional change.
5 Satisfied users of version 0.62 can skip this update.
6 + Fix : [RT #144052] : Add support for 5.37.3s PADSV_STORE optimization
7 B.pm-related tests have been taught about this new thing.
8 Thanks Richard Leach for contributing a patch.
11 0.62 2017-11-04 16:35 UTC
12 + Fix : [RT #123314] : Compatibility with CV-in-stash optimisation
13 Thanks Father Chrysostomos for reporting and contributing a
16 0.61 2017-01-24 15:30 UTC
17 + Fix : [RT #115792] : Latest blead stack unwind work causes infloop
19 A change in how the core frees temporary values after eval
20 interacted badly with Variable::Magic and caused infinite loops
21 when a free callback was attached to a wizard. This change was
22 temporarily reverted, but is going to be reinstated, and
23 Variable::Magic is now able to play nicely when this happens.
24 Thanks Peter Rabbitson for reporting and David Mitchell for
28 0.60 2016-09-06 22:30 UTC
29 + Chg : A large chunk of boilerplate XS code, which is also used in
30 other XS modules, has been factored out of the main .xs file
31 to a collection of .h files in the xsh subdirectory.
32 + Fix : [RT #128989] : Bleadperl v5.25.3-266-g1d7e644 breaks V::M.
33 Len magic is no longer called for negative array indices
34 fetches, so the relevant tests are now skipped.
35 Thanks Andreas Koenig for reporting.
37 0.59 2015-10-05 19:05 UTC
38 + Chg : The magic callbacks are now always executed in a new stack.
39 This should have no negative impact (performance-wise or
40 behaviour-wise) on your code, but may actually fix some obscure
42 + Fix : [RT #107294] : Crash during install of Variable-Magic-0.58
43 running "t\18-opinfo.t".
44 A recent change in the core implementation of transliterations
45 caused an undefined behaviour when it interacted with this
46 module, which resulted in visible stack corruption on Win32
47 perls compiled with MSVC when the op_info feature was enabled.
48 This was fixed by using a separate stack for the magic
50 Thanks Peter Stokes for reporting and providing greatly
52 + Fix : The object op_info feature will now handle correctly Unicode
53 transliteration, multideref and custom ops.
55 0.58 2015-07-21 16:00 UTC
56 + Add : If a non-len magic callback returns a reference, it will now
57 only be freed at the end of the statement that caused the
58 magic to trigger. This allows the user to attach free magic
59 (or a plain destructor) to a token returned from the callbacks
60 in order to defer an action after the magic is processed by
62 + Fix : Test failures of threads tests on systems with harsh resource
63 constraints causing the threads to exit() during run.
65 0.57 2015-04-17 15:20 UTC
66 + Chg : The new environment variable to enable thread tests on older
67 perls is PERL_FORCE_TEST_THREADS. Note that this variable
68 should only be turned on by authors.
69 + Fix : Segfaults when the module is loaded by several threads (or
70 Windows emulated processes) ran in parallel.
71 + Fix : Segfaults when the module is loaded in a thread, which spawns
72 itself a new thread, and that child thread outlives its parent.
73 + Fix : Small memory leaks of structures required for thread safety.
74 + Fix : Update the Windows ActivePerl + gcc 3.4 workaround for
75 ExtUtils::MakeMaker 7.04. Thanks Christian Walde for reporting
76 and feedback on this issue.
77 + Tst : The global destruction test will now be exercised on any perl
78 that has DEBUGGING set.
79 + Tst : Optional capturing tests in t/17-ctl.t that were only run when
80 Capture::Tiny was present were converted to an IPC::Open3
81 based helper and will now be run everywhere.
83 0.56 2015-03-11 15:15 UTC
84 + Fix : [RT #101410] : Install fails in blead
85 Even though the change that caused this error was reverted from
86 blead, lvalue uses of ERRSV have been removed from this module
87 so that there will be no breakage when this change is possibly
88 reintroduced in the following months.
89 Thanks Dave Rolsky for reporting.
90 + Tst : $ENV{$Config{ldlibpthname}} is now preserved on all platforms,
91 which will address failures of t/17-ctl.t with unusual
92 compilers (like icc) that link all their compiled objects to
94 + Tst : The global destruction test is now only run on perl 5.13.4 and
95 higher, and only if either Perl::Destruct::Level is installed
96 or PERL_DESTRUCT_LEVEL is set and the perl is a debugging perl.
97 This will solve rare crashes of t/15-self.t on perl 5.13.3 and
100 0.55 2014-10-20 23:45 UTC
101 + Fix : [RT #99319] : t/18-opinfo.t: test failure due to change in
103 The new METHOP op class added in perl 5.21.5 is now supported.
104 Thanks James E Keenan for reporting.
106 0.54 2014-09-22 17:30 UTC
107 + Add : The new constant VMG_COMPAT_CODE_COPY_CLONE evaluates to true
108 if your perl calls 'copy' magic when a magical code prototype
109 is cloned, which is currently the case for perl 5.17.0 and
111 + Fix : [RT #90205] : copy magic on subs puts raw CV in $_[3]
112 $_[3] will now contain a reference to the cloned code when
113 'copy' magic is called for a coderef.
114 Thanks Lukas Mai for reporting.
115 + Fix : t/35-stash.t has been taught about perl 5.21.4.
116 + Fix : Tests using run_perl() in t/17-ctl.t will no longer fail on
119 0.53 2013-09-01 17:50 UTC
120 This is a maintenance release. The code contains no functional change.
121 Satisfied users of version 0.52 can skip this update.
122 + Fix : [RT #86338] : typo fix.
123 Thanks dsteinbrunner@pobox.com for the patch.
124 + Tst : Author tests are no longer bundled with this distribution.
125 They are only made available to authors in the git repository.
127 0.52 2012-11-05 02:30 UTC
128 + Add : The new constant VMG_COMPAT_SCALAR_NOLEN evaluates to true
129 when your perl does not call 'len' magic for scalars, which
130 is the case for perl 5.17.4 and above.
131 This fixes RT #80388.
132 + Tst : t/35-stash.t has been taught about perl 5.17.4.
133 + Tst : Author tests overhaul.
135 0.51 2012-08-18 15:00 UTC
136 + Fix : It is now safe to call dispell() from inside 'free', 'copy' and
137 'uvar' callbacks to dispell the magic currently in use.
138 Thanks Clinton Gormley for reporting.
139 + Fix : Exceptions thrown from inside a 'free' callback are now always
140 consistently propagated outside of the callback. They used to
141 be lost when the 'free' callback was invoked at the end of an
142 eval block or string.
143 + Fix : The 'reset RMG flag' workaroundn used to allow wizards with
144 both 'uvar' and 'clear' magics to be cast onto a hash, has been
147 0.50 2012-06-24 23:00 UTC
148 + Fix : Less memory is leaked when a wizard is freed during global
149 destruction, or when an exception is thrown from a 'free'
151 + Fix : [RT #77991] : t/17-ctl.t fails on perl 5.14 and 5.16.
152 This was actually an issue with ActivePerl, and this test
153 has learned to cope with it.
154 Thanks Gisle Aas for reporting.
155 + Tst : t/35-stash.t has been taught about perl 5.17.1.
156 + Doc : Many clarifications.
158 0.49 2012-06-05 21:40 UTC
159 This is a maintenance release. The code contains no functional change.
160 Satisfied users of version 0.48 can skip this update.
161 + Fix : [RT #77644] : t/17_ctl.t fails in test 44 since 5.17.0.
162 This test has been taught about perl 5.17.0.
163 Thanks Reini Urban for reporting.
164 + Tst : t/99-kwalitee.t will be skipped when only problematic versions
165 of its dependencies are available.
167 0.48 2012-02-17 23:40 UTC
168 + Add : You can now pass a reference to undef as the magic callback in
169 order to install a no-op callback.
170 Thanks Florian Ragwitz for the suggestion.
172 0.47 2011-10-27 16:55 UTC
173 + Add : The new constant VMG_COMPAT_HASH_DELETE_NOUVAR_VOID evaluates
174 to true when "delete $hash{key}" does not call 'delete' uvar
175 magic in void context.
176 + Chg : The MAGIC tokens created by this module no longer use the
177 mg_private member for storing a "magical" signature.
178 + Fix : Triggering magic in a thread on a variable cloned from the main
179 interpreter, and when the wizard already went out of scope,
180 will not segfault anymore.
181 + Opt : The pointer table is no longer needed to ensure thread safety.
182 The size of the object code is about 8% smaller for threaded
184 + Tst : Threads tests will not fail anymore if resources constraints
185 prevent the system from creating all the required threads.
187 0.46 2011-01-23 16:45 UTC
188 + Fix : [RT #64866] : Assertion failure with perl 5.13.9.
189 The real problem was that dispell() wasn't properly resetting
190 the magical sv flags, which became visible in the test suite
191 only with perl 5.13.9.
192 Thanks Joshua ben Jore for reporting.
194 0.45 2010-11-21 23:15 UTC
195 This is a maintenance release. The code contains no functional change.
196 Users of 0.44 can skip this update.
197 + Doc : C++ compilers are officially NOT supported.
198 + Doc : The minimum perl 5.10.0 requirement for uvar magic has been
200 Thanks Peter Rabbitson for pointing this out and contributing a
202 + Tst : Tune for perl 5.13.7.
203 + Tst : Capture::Tiny will be used in t/17-ctl.t if and only if it can
204 capture a simple run.
206 0.44 2010-09-24 19:10 UTC
207 + Fix : Broken linkage on Windows with gcc 3.4, which appears in
208 particular when using ActivePerl's default compiler suite.
209 For those setups, the Variable::Magic shared library will now
210 be linked against the perl dll directly (instead of the import
211 library). This (should) fix RT #51483.
212 Thanks Christian Walde for helping to reproduce this failure
214 + Rem : Support for development perls from the 5.11 branch but older
215 than the 5.11.0 release was removed. This could cause more
216 recent setups to fail.
217 + Tst : Threads tests are now only run on perl 5.13.4 and higher.
218 They could segfault randomly because of what seems to be an
219 internal bug of Perl, which has been addressed in 5.13.4.
220 There is also an environment variable that allows you to
221 forcefully run those tests, but it should be set only for
222 author testing and not for end users.
224 0.43 2010-06-25 23:35 UTC
225 + Add : The new constant VMG_COMPAT_GLOB_GET tells you whether get magic
226 is called for globs. It's true starting perl 5.13.2.
227 + Chg : All callbacks are now called within an eval-like context.
228 Only free callbacks used to be called that way.
229 + Fix : Some exceptions thrown from a free callback could be lost.
230 + Fix : Croak messages could sometimes be repeated several times.
231 + Fix : t/41-clone.t segfaulting with perl 5.13.2.
233 0.42 2010-05-19 00:15 UTC
234 This is a maintenance release. The code contains no functional change.
235 Users of 0.41 can skip this update.
236 + Fix : Test failures with perl 5.13.
237 + Tst : Improve coverage.
239 0.41 2010-03-15 17:35 UTC
240 + Doc : Tweaks and fixups.
242 + Fix : Compatibility with the soon-to-be-released perl 5.12.0.
243 + Fix : Correctly propagate the errors thrown when variable destruction
244 happens at compile-time and not from inside eval STRING.
245 Thanks Florian Ragwitz and Ash Berlin for reporting.
247 0.40 2010-01-06 23:20 UTC
248 + Fix : Possible memory miswrites when passing data arguments to cast().
249 + Fix : Minor C portability tweaks.
251 0.39 2009-12-01 00:05 UTC
252 + Add : You can use a function name as a callback by passing a string
253 reference to wizard() instead of a code reference.
254 + Fix : Compatiblity with perl 5.11.1 and 5.11.2.
255 + Fix : Scalars stored into the data slot no longer leak.
256 + Fix : Thread destruction should not segfault anymore.
257 + Opt : As a result of removing the deprecated features, less memory is
258 used for both threaded (a pointer table is used instead of a
259 hash) and non-threaded (no global structure is needed anymore)
261 + Rem : As advertised in the precendent version, all the signature
262 related features were removed. This includes the 'sig' option
263 to wizard(), the getsig() and gensig() functions, and the SIG_*
266 0.38 2009-10-04 16:10 UTC
267 + Dep : All the signature-related features are DEPRECATED and will be
268 removed in december 2009. This includes the 'sig' option to
269 wizard(), the getsig() and gensig() functions, and the SIG_*
271 Afaik those features were never used in real life, and they make
272 the XS code slow and brittle. If you want your wizards to be
273 globally available, you'll have to handle that yourself by
274 storing them in a hash.
275 + Doc : More examples in a new COOKBOOK section.
276 + Fix : Compatiblity with the 5.11.0 release. The new compatibility
277 constant VMG_COMPAT_ARRAY_PUSH_NOLEN_VOID was added to cover
279 + Fix : Work around Kwalitee test misfailures.
281 0.37 2009-08-25 15:25 UTC
282 + Add : The new constant VMG_FORKSAFE can be tested to know whether the
283 module will behave nicely when fork()ing. It's currently always
284 true except on Windows where you need perl 5.10.1 for it to be
286 + Doc : Nits and clarifications.
288 0.36 2009-07-05 16:30 UTC
289 + Chg : getdata() now returns an empty list when no magic is present.
290 It used to return undef but did not croak as stated in the doc.
291 Thanks Matt S. Trout for pointing this out.
292 + Fix : Building and tests with ActiveState Perl 5.8 build >= 822.
294 0.35 2009-05-15 20:50 UTC
295 This is a maintenance release. Users of 0.34 can skip this update.
296 + Chg : uvar magic used to be enabled for 5.9.5. It now requires 5.10 or
298 + Fix : Silence compilation warnings for cxinc().
299 + Rem : The workaround introduced in 0.31 for the "Unknown errors" issue
300 was removed, as regression tests show that 0.34 provides a
302 + Tst : Skip t/40-threads.t on 5.8.x with old versions of threads and
305 0.34 2009-04-19 16:55 UTC
306 + Fix : Destruction of wizards in require.
307 + Fix : "panic: restartop" in 5.10 when dieing at compile time triggers
310 0.33 2009-03-26 00:00 UTC
311 + Chg : cast() and getsig() now croak too when an invalid signature is
313 + Fix : It was possible to generate with gensig() the same signature
314 twice before actually defining the wizards.
315 + Tst : More stash tests.
316 + Tst : Test when the magic takes place in some cases.
317 + Tst : Improved coverage for the op object feature.
319 0.32 2009-03-01 13:45 UTC
320 + Chg : dispell() and getdata() now croak when an invalid signature is
322 + Doc : More examples and a brand new synopsis.
323 + Fix : The signature is no longer stored in the mg_private member of
324 the MAGIC struct. This fixes possible clashes with magics from
326 + Fix : op info objects weren't blessed into the right class.
327 + Fix : Races when initializing the op names cache under threads.
329 0.31 2009-02-19 23:50 UTC
330 + Doc : A somewhat better introduction. The FUNCTION section was moved
331 before CONSTANTS and HISTORY since it's more important. And
332 'assignation' is really 'assignment', says Ricardo. :)
333 + Fix : The op_info features are now thread safe.
334 + Fix : Segfaults that occured when trying to get the op name during
336 + Fix : Segfaults and wrong "Unknown error" exceptions that happened
337 when dieing in require caused a free callback to fire.
338 Thanks Florian Ragwitz for reporting.
340 0.30 2009-02-12 17:05 UTC
341 + Add : You can now get in all the callbacks either the name or a B::OP
342 object representing the current op if you pass the new 'op_info'
343 option to wizard() with respective values VMG_OP_INFO_NAME and
345 + Doc : Document magic on array/hashes values.
346 + Fix : Completely skip free callbacks during global destruction.
347 + Tst : Tests now pass again on 5.8.3 and lower (they were broken since
349 + Tst : Test magic on symbol table and on array/hash values.
351 0.29 2009-02-08 11:10 UTC
352 + Add : Set $_[2] to the default length for len magic on scalars.
353 + Chg : Perl 5.8 is required.
354 + Chg : The CLONE method will no longer be defined for non-threaded
357 + Fix : The logic for turning off the GMAGICAL flag on hashes when no
358 uvar magic is involved could do nasty things on tied hashes.
359 + Upd : More resources in META.yml.
361 0.28 2009-01-24 17:05 UTC
362 + Add : The 'copy_key' option to wizard(), that enables the safe edition
363 of $_[2] in uvar callbacks to redirect actions to another key.
364 + Fix : Exception objects thrown from callbacks at compile time were not
366 + Fix : free callbacks triggered during global destruction could lead to
367 segfaults because the wizard was already freed.
368 + Fix : Refcount of scalars with free callback.
369 + Fix : Segfaults when using get or uvar magic simultaneously with clear
371 + Doc : The documentation about what the callbacks take and should
372 return is now somewhat clearer.
374 0.27 2009-01-18 23:40 UTC
375 + Fix : Offset of 1 with len magic on scalars.
376 + Fix : Segfaults that seem to happen when one croak in a callback at
377 compile time (thanks Ash Berlin for the testcase).
378 + Upd : Resources in META.yml (Florian Ragwitz)
379 + Tst : Large cleanup resulting in a wider set of tested behaviours.
381 0.26 2008-11-29 22:05 UTC
382 + Fix : Leaks of cloned coderefs that access lexicals.
383 + Fix : Building with maint-5.8 and blead (thanks Andreas Koenig).
385 0.25 2008-11-12 19:40 UTC
386 + Fix : Compatibility with 5.8.9.
387 + Fix : Old Pod::Coverage don't ignore CLONE.
388 + Upd : META.yml spec updated to 1.4.
390 0.24 2008-10-12 14:55 UTC
391 + Fix : Really fix it.
393 0.23 2008-10-11 17:25 UTC
394 + Fix : Building on perls with multiplicity but not ithreads.
396 0.22 2008-09-29 19:40 UTC
397 + Doc : Explain how magic differs from overloading.
398 + Fix : Disable thread safety for perl 5.8 on Windows. If you want it
399 enabled, reliable feedback is welcome.
401 0.21_02 2008-09-28 23:10 UTC
402 + Fix : Hide previously deleted magic tokens in vmg_svt_free (Yuval
405 0.21_01 2008-09-22 13:25 UTC
406 + Chg : Shrink the context data.
407 + Fix : Enable thread safety features for perls that just lack
409 + Tst : Output threads and threads::shared versions in threads tests.
411 0.20 2008-09-20 23:35 UTC
412 + Fix : The module is now thread safe. You can test if it had been
413 built with thread safety features enabled through the
414 VMG_THREADSAFE constant.
415 + Fix : Correct backtrace when wizard() croaks.
416 + Fix : 'cast $a, undef' should throw an 'invalid wizard' error instead
417 of an 'invalid signature'.
419 0.19 2008-07-05 15:05 UTC
420 + Add : The patchlevel with which the module has been built is now
421 exported with the VMG_PERL_PATCHLEVEL constant.
422 + Chg : Version checking macros overhaul.
423 + Fix : 'uvar' magic should only be enabled in maint-5.10 and higher
424 since it's never going to be backported to 5.8.
425 + Fix : Likewise, the copy callback API change should only be enabled in
427 + Fix : Instead of those ackward fake refcount increments in the wizard
428 destructor, flag the wizard with SVf_BREAK and force temps
429 cleanup. This should fix the wizard destruction for all perls,
430 and solves the leak introduced by the previous solution.
432 0.18 2008-07-04 12:20 UTC
433 + Fix : Enable uvar magic when patchlevel >= 28419.
434 + Fix : Set VMG_COMPAT_ARRAY_PUSH_NOLEN for Windows ActiveState Perl
437 0.17 2008-05-11 09:05 UTC
438 + Fix : 5.8.4 and lower don't have mPUSHi. Gah. Yeah, I know, I should
441 0.16 2008-05-10 22:05 UTC
442 + Add : The samples/copy.pl script.
443 + Chg : The sv_magical() + vmg_mg_magical() combo was simplified into
445 + Tst : t/33-code.t was testing scalars, not code.
446 + Tst : is() and like() are better than ok().
447 + Tst : 100% coverage reached.
449 0.15 2008-04-11 18:25 UTC
450 + Chg : Factor vmg_cb_call{1,2,3}() into one function.
451 + Fix : len magic is no longer called when taking the length() of a
452 magical scalar since p32969. The VMG_COMPAT_SCALAR_LENGTH_NOLEN
453 constant was added to cover this.
454 + Tst : More tests for t/22-len.t.
456 0.14 2008-03-24 12:35 UTC
457 + Fix : t/16-huf.t failures on Solaris and FreeBSD caused by not
458 updating mg->mg_ptr after Renew-ing it on dispell.
459 + Fix : Undefining MGf_DUP caused the wizard's magic to be wrongly
460 initialized. MGf_DUP now appears as true from the user point of
461 view, but the dup callback isn't actually set.
462 + Fix : Warnings with blead due to copy callbacks now taking an I32 (API
464 + Fix : vmg_svt_val() and vmg_uvar_del() aren't required if no uvar
466 + Tst : Tests now output the version of optional modules loaded.
468 0.13 2008-03-19 14:35 UTC
469 + Doc : Link to coverage report.
470 + Fix : Correct dependencies listing in META.yml.
471 + Tst : Improved test coverage.
472 + Tst : Print the patchlevel as a comment.
473 + Tst : Use is() where it's relevant.
474 + Tst : t/16-huf.t now really tests interaction with H::U::FH.
476 0.12 2008-02-07 18:15 UTC
477 + Fix : POD error. Thanks to Chris Williams (BinGOs) for the quick
480 0.11 2008-02-07 17:55 UTC
481 + Add : Copy callbacks now receive the current key/index in $_[2].
482 The current value/element is now in $_[3].
483 + Chg : The trigger of copy magic on list assignment with perls greater
484 than 5.10.0 was caused by uvar magic. Hence,
485 VMG_COMPAT_HASH_LISTASSIGN_COPY was removed. Use VMG_UVAR
487 + Fix : Build failures on patched perls.
488 + Tst : Added missing exported symbols to 01-import.t.
490 0.10 2008-02-04 11:30 UTC
491 + Add : New script : samples/vm_vs_tie.pl, that benchmarks our uvar
492 magic versus tied hashes.
493 + Add : The VMG_COMPAT_* constants can be used from userspace to check
494 perl magic abilities.
495 + Fix : Callbacks that returned undef made us croak, breaking the
496 variable behaviour (regression test in 14-callbacks.t).
497 + Fix : uvar callbacks weren't tested for non-NULL-ity before being
498 called (regression test in 28-uvar.t).
499 + Tst : Fix typo in 25-copy.t that prevented Tie::Hash tests to be ran.
501 0.09 2008-02-02 11:30 UTC
502 + Doc : Explicitely say that uvar callbacks are safely ignored for
504 + Doc : Document caveats and fix the usual set of typos.
505 + Fix : vmg_dispell() didn't check if the ext magic were ours when
506 counting wizards that have uvar callbacks, resulting in a
507 possible memory misread.
508 + Fix : getdata() now returns directly the data object, and no longer a
509 copy. This caused a leak.
510 + Tst : Prefix author tests by 9*-.
511 + Tst : New optional author test : 95-portability-files.t, that uses
512 Test::Portability::Files when it's present.
513 + Tst : New test : 14-self.t, that tests application of magic on the
515 + Tst : Move Hash::Util::FieldHash tests out of 11-multiple.t to
518 0.08 2008-02-01 16:55 UTC
519 + Add : copy magic for tied arrays/hashes.
521 + Add : uvar magics : fetch, store, exists, delete for hashes.
524 Internal development versions.

527 + Chg : 5.7.3 is now officially required.
528 + Fix : "data" test failures on 5.8.{0,2}.
529 + Fix : Drand01() vs rand().
531 0.05 2007-11-19 09:10 UTC
532 + Fix : 5.10.0_RC1 compatibility fix.
534 0.04 2007-08-28 12:25 UTC
535 + Chg : s/require (XSLoader)/use $1/.
536 + Fix : Tests are now strict.
537 + Fix : Complete dependencies.
539 0.03 2007-08-01 17:20 UTC
540 + Add : Passing the signature of an already defined magic to wizard()
541 now returns the corresponding magic object.
542 + Add : You can pass the numeric signature as the wizard argument of
543 cast(), dispell() and getdata().
544 + Add : Any argument specified after the wizard (or the signature) in a
545 call to cast() is now passed to the private data constructor in
547 + Chg : $_[0] is now always a reference to the magic variable in all
548 callbacks. The reason for changing from the previous behaviour
549 is that one may want to apply the same magic to a plain scalar
550 and to a scalar reference, and needs a way to distinguish
551 between them in the callback (say, ref()).
552 + Fix : Wizard object destruction used not to free the signature.
554 0.02 2007-07-27 13:50 UTC
555 + Fix : In response to test report 548152 :
556 Newx() and SvMAGIC_set() not present on older perls.
557 + Fix : In response to test report 548275 :
558 Since perl 5.9.5, 'clear' magic is invoked when an array is
559 undefined (bug #43357). Moreover, 'len' magic is no longer
560 called by pushing an element since perl 5.9.3.
561 + Fix : Missing glob test in MANIFEST.
