1 Revision history for Variable-Magic
3 0.50 2012-06-24 23:00 UTC
4 + Fix : Less memory is leaked when a wizard is freed during global
5 destruction, or when an exception is thrown from a 'free'
7 + Fix : [RT #77991] : t/17-ctl.t fails on perl 5.14 and 5.16.
8 This was actually an issue with ActivePerl, and this test
9 has learned to cope with it.
10 Thanks Gisle Aas for reporting.
11 + Tst : t/35-stash.t has been taught about perl 5.17.1.
12 + Doc : Many clarifications.
14 0.49 2012-06-05 21:40 UTC
15 This is a maintenance release. The code contains no functional change.
16 Satisfied users of version 0.48 can skip this update.
17 + Fix : [RT #77644] : t/17_ctl.t fails in test 44 since 5.17.0.
18 This test has been taught about perl 5.17.0.
19 Thanks Reini Urban for reporting.
20 + Tst : t/99-kwalitee.t will be skipped when only problematic versions
21 of its dependencies are available.
23 0.48 2012-02-17 23:40 UTC
24 + Add : You can now pass a reference to undef as the magic callback in
25 order to install a no-op callback.
26 Thanks Florian Ragwitz for the suggestion.
28 0.47 2011-10-27 16:55 UTC
29 + Add : The new constant VMG_COMPAT_HASH_DELETE_NOUVAR_VOID evaluates
30 to true when "delete $hash{key}" does not call 'delete' uvar
31 magic in void context.
32 + Chg : The MAGIC tokens created by this module no longer use the
33 mg_private member for storing a "magical" signature.
34 + Fix : Triggering magic in a thread on a variable cloned from the main
35 interpreter, and when the wizard already went out of scope,
36 will not segfault anymore.
37 + Opt : The pointer table is no longer needed to ensure thread safety.
38 The size of the object code is about 8% smaller for threaded
40 + Tst : Threads tests will not fail anymore if resources constraints
41 prevent the system from creating all the required threads.
43 0.46 2011-01-23 16:45 UTC
44 + Fix : [RT #64866] : Assertion failure with perl 5.13.9.
45 The real problem was that dispell() wasn't properly resetting
46 the magical sv flags, which became visible in the test suite
47 only with perl 5.13.9.
48 Thanks Joshua ben Jore for reporting.
50 0.45 2010-11-21 23:15 UTC
51 This is a maintenance release. The code contains no functional change.
52 Users of 0.44 can skip this update.
53 + Doc : C++ compilers are officially NOT supported.
54 + Doc : The minimum perl 5.10.0 requirement for uvar magic has been
56 Thanks Peter Rabbitson for pointing this out and contributing a
58 + Tst : Tune for perl 5.13.7.
59 + Tst : Capture::Tiny will be used in t/17-ctl.t if and only if it can
62 0.44 2010-09-24 19:10 UTC
63 + Fix : Broken linkage on Windows with gcc 3.4, which appears in
64 particular when using ActivePerl's default compiler suite.
65 For those setups, the Variable::Magic shared library will now
66 be linked against the perl dll directly (instead of the import
67 library). This (should) fix RT #51483.
68 Thanks Christian Walde for helping to reproduce this failure
70 + Rem : Support for development perls from the 5.11 branch but older
71 than the 5.11.0 release was removed. This could cause more
72 recent setups to fail.
73 + Tst : Threads tests are now only run on perl 5.13.4 and higher.
74 They could segfault randomly because of what seems to be an
75 internal bug of Perl, which has been addressed in 5.13.4.
76 There is also an environment variable that allows you to
77 forcefully run those tests, but it should be set only for
78 author testing and not for end users.
80 0.43 2010-06-25 23:35 UTC
81 + Add : The new constant VMG_COMPAT_GLOB_GET tells you whether get magic
82 is called for globs. It's true starting perl 5.13.2.
83 + Chg : All callbacks are now called within an eval-like context.
84 Only free callbacks used to be called that way.
85 + Fix : Some exceptions thrown from a free callback could be lost.
86 + Fix : Croak messages could sometimes be repeated several times.
87 + Fix : t/41-clone.t segfaulting with perl 5.13.2.
89 0.42 2010-05-19 00:15 UTC
90 This is a maintenance release. The code contains no functional change.
91 Users of 0.41 can skip this update.
92 + Fix : Test failures with perl 5.13.
93 + Tst : Improve coverage.
95 0.41 2010-03-15 17:35 UTC
96 + Doc : Tweaks and fixups.
98 + Fix : Compatibility with the soon-to-be-released perl 5.12.0.
99 + Fix : Correctly propagate the errors thrown when variable destruction
100 happens at compile-time and not from inside eval STRING.
101 Thanks Florian Ragwitz and Ash Berlin for reporting.
103 0.40 2010-01-06 23:20 UTC
104 + Fix : Possible memory miswrites when passing data arguments to cast().
105 + Fix : Minor C portability tweaks.
107 0.39 2009-12-01 00:05 UTC
108 + Add : You can use a function name as a callback by passing a string
109 reference to wizard() instead of a code reference.
110 + Fix : Compatiblity with perl 5.11.1 and 5.11.2.
111 + Fix : Scalars stored into the data slot no longer leak.
112 + Fix : Thread destruction should not segfault anymore.
113 + Opt : As a result of removing the deprecated features, less memory is
114 used for both threaded (a pointer table is used instead of a
115 hash) and non-threaded (no global structure is needed anymore)
117 + Rem : As advertised in the precendent version, all the signature
118 related features were removed. This includes the 'sig' option
119 to wizard(), the getsig() and gensig() functions, and the SIG_*
122 0.38 2009-10-04 16:10 UTC
123 + Dep : All the signature-related features are DEPRECATED and will be
124 removed in december 2009. This includes the 'sig' option to
125 wizard(), the getsig() and gensig() functions, and the SIG_*
127 Afaik those features were never used in real life, and they make
128 the XS code slow and brittle. If you want your wizards to be
129 globally available, you'll have to handle that yourself by
130 storing them in a hash.
131 + Doc : More examples in a new COOKBOOK section.
132 + Fix : Compatiblity with the 5.11.0 release. The new compatibility
133 constant VMG_COMPAT_ARRAY_PUSH_NOLEN_VOID was added to cover
135 + Fix : Work around Kwalitee test misfailures.
137 0.37 2009-08-25 15:25 UTC
138 + Add : The new constant VMG_FORKSAFE can be tested to know whether the
139 module will behave nicely when fork()ing. It's currently always
140 true except on Windows where you need perl 5.10.1 for it to be
142 + Doc : Nits and clarifications.
144 0.36 2009-07-05 16:30 UTC
145 + Chg : getdata() now returns an empty list when no magic is present.
146 It used to return undef but did not croak as stated in the doc.
147 Thanks Matt S. Trout for pointing this out.
148 + Fix : Building and tests with ActiveState Perl 5.8 build >= 822.
150 0.35 2009-05-15 20:50 UTC
151 This is a maintenance release. Users of 0.34 can skip this update.
152 + Chg : uvar magic used to be enabled for 5.9.5. It now requires 5.10 or
154 + Fix : Silence compilation warnings for cxinc().
155 + Rem : The workaround introduced in 0.31 for the "Unknown errors" issue
156 was removed, as regression tests show that 0.34 provides a
158 + Tst : Skip t/40-threads.t on 5.8.x with old versions of threads and
161 0.34 2009-04-19 16:55 UTC
162 + Fix : Destruction of wizards in require.
163 + Fix : "panic: restartop" in 5.10 when dieing at compile time triggers
166 0.33 2009-03-26 00:00 UTC
167 + Chg : cast() and getsig() now croak too when an invalid signature is
169 + Fix : It was possible to generate with gensig() the same signature
170 twice before actually defining the wizards.
171 + Tst : More stash tests.
172 + Tst : Test when the magic takes place in some cases.
173 + Tst : Improved coverage for the op object feature.
175 0.32 2009-03-01 13:45 UTC
176 + Chg : dispell() and getdata() now croak when an invalid signature is
178 + Doc : More examples and a brand new synopsis.
179 + Fix : The signature is no longer stored in the mg_private member of
180 the MAGIC struct. This fixes possible clashes with magics from
182 + Fix : op info objects weren't blessed into the right class.
183 + Fix : Races when initializing the op names cache under threads.
185 0.31 2009-02-19 23:50 UTC
186 + Doc : A somewhat better introduction. The FUNCTION section was moved
187 before CONSTANTS and HISTORY since it's more important. And
188 'assignation' is really 'assignment', says Ricardo. :)
189 + Fix : The op_info features are now thread safe.
190 + Fix : Segfaults that occured when trying to get the op name during
192 + Fix : Segfaults and wrong "Unknown error" exceptions that happened
193 when dieing in require caused a free callback to fire.
194 Thanks Florian Ragwitz for reporting.
196 0.30 2009-02-12 17:05 UTC
197 + Add : You can now get in all the callbacks either the name or a B::OP
198 object representing the current op if you pass the new 'op_info'
199 option to wizard() with respective values VMG_OP_INFO_NAME and
201 + Doc : Document magic on array/hashes values.
202 + Fix : Completely skip free callbacks during global destruction.
203 + Tst : Tests now pass again on 5.8.3 and lower (they were broken since
205 + Tst : Test magic on symbol table and on array/hash values.
207 0.29 2009-02-08 11:10 UTC
208 + Add : Set $_[2] to the default length for len magic on scalars.
209 + Chg : Perl 5.8 is required.
210 + Chg : The CLONE method will no longer be defined for non-threaded
213 + Fix : The logic for turning off the GMAGICAL flag on hashes when no
214 uvar magic is involved could do nasty things on tied hashes.
215 + Upd : More resources in META.yml.
217 0.28 2009-01-24 17:05 UTC
218 + Add : The 'copy_key' option to wizard(), that enables the safe edition
219 of $_[2] in uvar callbacks to redirect actions to another key.
220 + Fix : Exception objects thrown from callbacks at compile time were not
222 + Fix : free callbacks triggered during global destruction could lead to
223 segfaults because the wizard was already freed.
224 + Fix : Refcount of scalars with free callback.
225 + Fix : Segfaults when using get or uvar magic simultaneously with clear
227 + Doc : The documentation about what the callbacks take and should
228 return is now somewhat clearer.
230 0.27 2009-01-18 23:40 UTC
231 + Fix : Offset of 1 with len magic on scalars.
232 + Fix : Segfaults that seem to happen when one croak in a callback at
233 compile time (thanks Ash Berlin for the testcase).
234 + Upd : Resources in META.yml (Florian Ragwitz)
235 + Tst : Large cleanup resulting in a wider set of tested behaviours.
237 0.26 2008-11-29 22:05 UTC
238 + Fix : Leaks of cloned coderefs that access lexicals.
239 + Fix : Building with maint-5.8 and blead (thanks Andreas Koenig).
241 0.25 2008-11-12 19:40 UTC
242 + Fix : Compatibility with 5.8.9.
243 + Fix : Old Pod::Coverage don't ignore CLONE.
244 + Upd : META.yml spec updated to 1.4.
246 0.24 2008-10-12 14:55 UTC
247 + Fix : Really fix it.
249 0.23 2008-10-11 17:25 UTC
250 + Fix : Building on perls with multiplicity but not ithreads.
252 0.22 2008-09-29 19:40 UTC
253 + Doc : Explain how magic differs from overloading.
254 + Fix : Disable thread safety for perl 5.8 on Windows. If you want it
255 enabled, reliable feedback is welcome.
257 0.21_02 2008-09-28 23:10 UTC
258 + Fix : Hide previously deleted magic tokens in vmg_svt_free (Yuval
261 0.21_01 2008-09-22 13:25 UTC
262 + Chg : Shrink the context data.
263 + Fix : Enable thread safety features for perls that just lack
265 + Tst : Output threads and threads::shared versions in threads tests.
267 0.20 2008-09-20 23:35 UTC
268 + Fix : The module is now thread safe. You can test if it had been
269 built with thread safety features enabled through the
270 VMG_THREADSAFE constant.
271 + Fix : Correct backtrace when wizard() croaks.
272 + Fix : 'cast $a, undef' should throw an 'invalid wizard' error instead
273 of an 'invalid signature'.
275 0.19 2008-07-05 15:05 UTC
276 + Add : The patchlevel with which the module has been built is now
277 exported with the VMG_PERL_PATCHLEVEL constant.
278 + Chg : Version checking macros overhaul.
279 + Fix : 'uvar' magic should only be enabled in maint-5.10 and higher
280 since it's never going to be backported to 5.8.
281 + Fix : Likewise, the copy callback API change should only be enabled in
283 + Fix : Instead of those ackward fake refcount increments in the wizard
284 destructor, flag the wizard with SVf_BREAK and force temps
285 cleanup. This should fix the wizard destruction for all perls,
286 and solves the leak introduced by the previous solution.
288 0.18 2008-07-04 12:20 UTC
289 + Fix : Enable uvar magic when patchlevel >= 28419.
290 + Fix : Set VMG_COMPAT_ARRAY_PUSH_NOLEN for Windows ActiveState Perl
293 0.17 2008-05-11 09:05 UTC
294 + Fix : 5.8.4 and lower don't have mPUSHi. Gah. Yeah, I know, I should
297 0.16 2008-05-10 22:05 UTC
298 + Add : The samples/copy.pl script.
299 + Chg : The sv_magical() + vmg_mg_magical() combo was simplified into
301 + Tst : t/33-code.t was testing scalars, not code.
302 + Tst : is() and like() are better than ok().
303 + Tst : 100% coverage reached.
305 0.15 2008-04-11 18:25 UTC
306 + Chg : Factor vmg_cb_call{1,2,3}() into one function.
307 + Fix : len magic is no longer called when taking the length() of a
308 magical scalar since p32969. The VMG_COMPAT_SCALAR_LENGTH_NOLEN
309 constant was added to cover this.
310 + Tst : More tests for t/22-len.t.
312 0.14 2008-03-24 12:35 UTC
313 + Fix : t/16-huf.t failures on Solaris and FreeBSD caused by not
314 updating mg->mg_ptr after Renew-ing it on dispell.
315 + Fix : Undefining MGf_DUP caused the wizard's magic to be wrongly
316 initialized. MGf_DUP now appears as true from the user point of
317 view, but the dup callback isn't actually set.
318 + Fix : Warnings with blead due to copy callbacks now taking an I32 (API
320 + Fix : vmg_svt_val() and vmg_uvar_del() aren't required if no uvar
322 + Tst : Tests now output the version of optional modules loaded.
324 0.13 2008-03-19 14:35 UTC
325 + Doc : Link to coverage report.
326 + Fix : Correct dependencies listing in META.yml.
327 + Tst : Improved test coverage.
328 + Tst : Print the patchlevel as a comment.
329 + Tst : Use is() where it's relevant.
330 + Tst : t/16-huf.t now really tests interaction with H::U::FH.
332 0.12 2008-02-07 18:15 UTC
333 + Fix : POD error. Thanks to Chris Williams (BinGOs) for the quick
336 0.11 2008-02-07 17:55 UTC
337 + Add : Copy callbacks now receive the current key/index in $_[2].
338 The current value/element is now in $_[3].
339 + Chg : The trigger of copy magic on list assignment with perls greater
340 than 5.10.0 was caused by uvar magic. Hence,
341 VMG_COMPAT_HASH_LISTASSIGN_COPY was removed. Use VMG_UVAR
343 + Fix : Build failures on patched perls.
344 + Tst : Added missing exported symbols to 01-import.t.
346 0.10 2008-02-04 11:30 UTC
347 + Add : New script : samples/vm_vs_tie.pl, that benchmarks our uvar
348 magic versus tied hashes.
349 + Add : The VMG_COMPAT_* constants can be used from userspace to check
350 perl magic abilities.
351 + Fix : Callbacks that returned undef made us croak, breaking the
352 variable behaviour (regression test in 14-callbacks.t).
353 + Fix : uvar callbacks weren't tested for non-NULL-ity before being
354 called (regression test in 28-uvar.t).
355 + Tst : Fix typo in 25-copy.t that prevented Tie::Hash tests to be ran.
357 0.09 2008-02-02 11:30 UTC
358 + Doc : Explicitely say that uvar callbacks are safely ignored for
360 + Doc : Document caveats and fix the usual set of typos.
361 + Fix : vmg_dispell() didn't check if the ext magic were ours when
362 counting wizards that have uvar callbacks, resulting in a
363 possible memory misread.
364 + Fix : getdata() now returns directly the data object, and no longer a
365 copy. This caused a leak.
366 + Tst : Prefix author tests by 9*-.
367 + Tst : New optional author test : 95-portability-files.t, that uses
368 Test::Portability::Files when it's present.
369 + Tst : New test : 14-self.t, that tests application of magic on the
371 + Tst : Move Hash::Util::FieldHash tests out of 11-multiple.t to
374 0.08 2008-02-01 16:55 UTC
375 + Add : copy magic for tied arrays/hashes.
377 + Add : uvar magics : fetch, store, exists, delete for hashes.
380 Internal development versions.
382 0.06 2007-11-20 10:10 UTC
383 + Chg : 5.7.3 is now officially required.
384 + Fix : "data" test failures on 5.8.{0,2}.
385 + Fix : Drand01() vs rand().
387 0.05 2007-11-19 09:10 UTC
388 + Fix : 5.10.0_RC1 compatibility fix.
390 0.04 2007-08-28 12:25 UTC
391 + Chg : s/require (XSLoader)/use $1/.
392 + Fix : Tests are now strict.
393 + Fix : Complete dependencies.
395 0.03 2007-08-01 17:20 UTC
396 + Add : Passing the signature of an already defined magic to wizard()
397 now returns the corresponding magic object.
398 + Add : You can pass the numeric signature as the wizard argument of
399 cast(), dispell() and getdata().
400 + Add : Any argument specified after the wizard (or the signature) in a
401 call to cast() is now passed to the private data constructor in
403 + Chg : $_[0] is now always a reference to the magic variable in all
404 callbacks. The reason for changing from the previous behaviour
405 is that one may want to apply the same magic to a plain scalar
406 and to a scalar reference, and needs a way to distinguish
407 between them in the callback (say, ref()).
408 + Fix : Wizard object destruction used not to free the signature.
410 0.02 2007-07-27 13:50 UTC
411 + Fix : In response to test report 548152 :
412 Newx() and SvMAGIC_set() not present on older perls.
413 + Fix : In response to test report 548275 :
414 Since perl 5.9.5, 'clear' magic is invoked when an array is
415 undefined (bug #43357). Moreover, 'len' magic is no longer
416 called by pushing an element since perl 5.9.3.
417 + Fix : Missing glob test in MANIFEST.
419 0.01 2007-07-25 16:15 UTC
420 First version, released on an unsuspecting world.
