1 Revision history for Variable-Magic
3 0.49 2012-06-05 21:40 UTC
4 This is a maintenance release. The code contains no functional change.
5 Satisfied users of version 0.48 can skip this update.
6 + Fix : [RT #77644] : t/17_ctl.t fails in test 44 since 5.17.0.
7 This test has been taught about perl 5.17.0.
8 Thanks Reini Urban for reporting.
9 + Tst : t/99-kwalitee.t will be skipped when only problematic versions
10 of its dependencies are available.
12 0.48 2012-02-17 23:40 UTC
13 + Add : You can now pass a reference to undef as the magic callback in
14 order to install a no-op callback.
15 Thanks Florian Ragwitz for the suggestion.
17 0.47 2011-10-27 16:55 UTC
18 + Add : The new constant VMG_COMPAT_HASH_DELETE_NOUVAR_VOID evaluates
19 to true when "delete $hash{key}" does not call 'delete' uvar
20 magic in void context.
21 + Chg : The MAGIC tokens created by this module no longer use the
22 mg_private member for storing a "magical" signature.
23 + Fix : Triggering magic in a thread on a variable cloned from the main
24 interpreter, and when the wizard already went out of scope,
25 will not segfault anymore.
26 + Opt : The pointer table is no longer needed to ensure thread safety.
27 The size of the object code is about 8% smaller for threaded
29 + Tst : Threads tests will not fail anymore if resources constraints
30 prevent the system from creating all the required threads.
32 0.46 2011-01-23 16:45 UTC
33 + Fix : [RT #64866] : Assertion failure with perl 5.13.9.
34 The real problem was that dispell() wasn't properly resetting
35 the magical sv flags, which became visible in the test suite
36 only with perl 5.13.9.
37 Thanks Joshua ben Jore for reporting.
39 0.45 2010-11-21 23:15 UTC
40 This is a maintenance release. The code contains no functional change.
41 Users of 0.44 can skip this update.
42 + Doc : C++ compilers are officially NOT supported.
43 + Doc : The minimum perl 5.10.0 requirement for uvar magic has been
45 Thanks Peter Rabbitson for pointing this out and contributing a
47 + Tst : Tune for perl 5.13.7.
48 + Tst : Capture::Tiny will be used in t/17-ctl.t if and only if it can
51 0.44 2010-09-24 19:10 UTC
52 + Fix : Broken linkage on Windows with gcc 3.4, which appears in
53 particular when using ActivePerl's default compiler suite.
54 For those setups, the Variable::Magic shared library will now
55 be linked against the perl dll directly (instead of the import
56 library). This (should) fix RT #51483.
57 Thanks Christian Walde for helping to reproduce this failure
59 + Rem : Support for development perls from the 5.11 branch but older
60 than the 5.11.0 release was removed. This could cause more
61 recent setups to fail.
62 + Tst : Threads tests are now only run on perl 5.13.4 and higher.
63 They could segfault randomly because of what seems to be an
64 internal bug of Perl, which has been addressed in 5.13.4.
65 There is also an environment variable that allows you to
66 forcefully run those tests, but it should be set only for
67 author testing and not for end users.
69 0.43 2010-06-25 23:35 UTC
70 + Add : The new constant VMG_COMPAT_GLOB_GET tells you whether get magic
71 is called for globs. It's true starting perl 5.13.2.
72 + Chg : All callbacks are now called within an eval-like context.
73 Only free callbacks used to be called that way.
74 + Fix : Some exceptions thrown from a free callback could be lost.
75 + Fix : Croak messages could sometimes be repeated several times.
76 + Fix : t/41-clone.t segfaulting with perl 5.13.2.
78 0.42 2010-05-19 00:15 UTC
79 This is a maintenance release. The code contains no functional change.
80 Users of 0.41 can skip this update.
81 + Fix : Test failures with perl 5.13.
82 + Tst : Improve coverage.
84 0.41 2010-03-15 17:35 UTC
85 + Doc : Tweaks and fixups.
87 + Fix : Compatibility with the soon-to-be-released perl 5.12.0.
88 + Fix : Correctly propagate the errors thrown when variable destruction
89 happens at compile-time and not from inside eval STRING.
90 Thanks Florian Ragwitz and Ash Berlin for reporting.
92 0.40 2010-01-06 23:20 UTC
93 + Fix : Possible memory miswrites when passing data arguments to cast().
94 + Fix : Minor C portability tweaks.
96 0.39 2009-12-01 00:05 UTC
97 + Add : You can use a function name as a callback by passing a string
98 reference to wizard() instead of a code reference.
99 + Fix : Compatiblity with perl 5.11.1 and 5.11.2.
100 + Fix : Scalars stored into the data slot no longer leak.
101 + Fix : Thread destruction should not segfault anymore.
102 + Opt : As a result of removing the deprecated features, less memory is
103 used for both threaded (a pointer table is used instead of a
104 hash) and non-threaded (no global structure is needed anymore)
106 + Rem : As advertised in the precendent version, all the signature
107 related features were removed. This includes the 'sig' option
108 to wizard(), the getsig() and gensig() functions, and the SIG_*
111 0.38 2009-10-04 16:10 UTC
112 + Dep : All the signature-related features are DEPRECATED and will be
113 removed in december 2009. This includes the 'sig' option to
114 wizard(), the getsig() and gensig() functions, and the SIG_*
116 Afaik those features were never used in real life, and they make
117 the XS code slow and brittle. If you want your wizards to be
118 globally available, you'll have to handle that yourself by
119 storing them in a hash.
120 + Doc : More examples in a new COOKBOOK section.
121 + Fix : Compatiblity with the 5.11.0 release. The new compatibility
122 constant VMG_COMPAT_ARRAY_PUSH_NOLEN_VOID was added to cover
124 + Fix : Work around Kwalitee test misfailures.
126 0.37 2009-08-25 15:25 UTC
127 + Add : The new constant VMG_FORKSAFE can be tested to know whether the
128 module will behave nicely when fork()ing. It's currently always
129 true except on Windows where you need perl 5.10.1 for it to be
131 + Doc : Nits and clarifications.
133 0.36 2009-07-05 16:30 UTC
134 + Chg : getdata() now returns an empty list when no magic is present.
135 It used to return undef but did not croak as stated in the doc.
136 Thanks Matt S. Trout for pointing this out.
137 + Fix : Building and tests with ActiveState Perl 5.8 build >= 822.
139 0.35 2009-05-15 20:50 UTC
140 This is a maintenance release. Users of 0.34 can skip this update.
141 + Chg : uvar magic used to be enabled for 5.9.5. It now requires 5.10 or
143 + Fix : Silence compilation warnings for cxinc().
144 + Rem : The workaround introduced in 0.31 for the "Unknown errors" issue
145 was removed, as regression tests show that 0.34 provides a
147 + Tst : Skip t/40-threads.t on 5.8.x with old versions of threads and
150 0.34 2009-04-19 16:55 UTC
151 + Fix : Destruction of wizards in require.
152 + Fix : "panic: restartop" in 5.10 when dieing at compile time triggers
155 0.33 2009-03-26 00:00 UTC
156 + Chg : cast() and getsig() now croak too when an invalid signature is
158 + Fix : It was possible to generate with gensig() the same signature
159 twice before actually defining the wizards.
160 + Tst : More stash tests.
161 + Tst : Test when the magic takes place in some cases.
162 + Tst : Improved coverage for the op object feature.
164 0.32 2009-03-01 13:45 UTC
165 + Chg : dispell() and getdata() now croak when an invalid signature is
167 + Doc : More examples and a brand new synopsis.
168 + Fix : The signature is no longer stored in the mg_private member of
169 the MAGIC struct. This fixes possible clashes with magics from
171 + Fix : op info objects weren't blessed into the right class.
172 + Fix : Races when initializing the op names cache under threads.
174 0.31 2009-02-19 23:50 UTC
175 + Doc : A somewhat better introduction. The FUNCTION section was moved
176 before CONSTANTS and HISTORY since it's more important. And
177 'assignation' is really 'assignment', says Ricardo. :)
178 + Fix : The op_info features are now thread safe.
179 + Fix : Segfaults that occured when trying to get the op name during
181 + Fix : Segfaults and wrong "Unknown error" exceptions that happened
182 when dieing in require caused a free callback to fire.
183 Thanks Florian Ragwitz for reporting.
185 0.30 2009-02-12 17:05 UTC
186 + Add : You can now get in all the callbacks either the name or a B::OP
187 object representing the current op if you pass the new 'op_info'
188 option to wizard() with respective values VMG_OP_INFO_NAME and
190 + Doc : Document magic on array/hashes values.
191 + Fix : Completely skip free callbacks during global destruction.
192 + Tst : Tests now pass again on 5.8.3 and lower (they were broken since
194 + Tst : Test magic on symbol table and on array/hash values.
196 0.29 2009-02-08 11:10 UTC
197 + Add : Set $_[2] to the default length for len magic on scalars.
198 + Chg : Perl 5.8 is required.
199 + Chg : The CLONE method will no longer be defined for non-threaded
202 + Fix : The logic for turning off the GMAGICAL flag on hashes when no
203 uvar magic is involved could do nasty things on tied hashes.
204 + Upd : More resources in META.yml.
206 0.28 2009-01-24 17:05 UTC
207 + Add : The 'copy_key' option to wizard(), that enables the safe edition
208 of $_[2] in uvar callbacks to redirect actions to another key.
209 + Fix : Exception objects thrown from callbacks at compile time were not
211 + Fix : free callbacks triggered during global destruction could lead to
212 segfaults because the wizard was already freed.
213 + Fix : Refcount of scalars with free callback.
214 + Fix : Segfaults when using get or uvar magic simultaneously with clear
216 + Doc : The documentation about what the callbacks take and should
217 return is now somewhat clearer.
219 0.27 2009-01-18 23:40 UTC
220 + Fix : Offset of 1 with len magic on scalars.
221 + Fix : Segfaults that seem to happen when one croak in a callback at
222 compile time (thanks Ash Berlin for the testcase).
223 + Upd : Resources in META.yml (Florian Ragwitz)
224 + Tst : Large cleanup resulting in a wider set of tested behaviours.
226 0.26 2008-11-29 22:05 UTC
227 + Fix : Leaks of cloned coderefs that access lexicals.
228 + Fix : Building with maint-5.8 and blead (thanks Andreas Koenig).
230 0.25 2008-11-12 19:40 UTC
231 + Fix : Compatibility with 5.8.9.
232 + Fix : Old Pod::Coverage don't ignore CLONE.
233 + Upd : META.yml spec updated to 1.4.
235 0.24 2008-10-12 14:55 UTC
236 + Fix : Really fix it.
238 0.23 2008-10-11 17:25 UTC
239 + Fix : Building on perls with multiplicity but not ithreads.
241 0.22 2008-09-29 19:40 UTC
242 + Doc : Explain how magic differs from overloading.
243 + Fix : Disable thread safety for perl 5.8 on Windows. If you want it
244 enabled, reliable feedback is welcome.
246 0.21_02 2008-09-28 23:10 UTC
247 + Fix : Hide previously deleted magic tokens in vmg_svt_free (Yuval
250 0.21_01 2008-09-22 13:25 UTC
251 + Chg : Shrink the context data.
252 + Fix : Enable thread safety features for perls that just lack
254 + Tst : Output threads and threads::shared versions in threads tests.
256 0.20 2008-09-20 23:35 UTC
257 + Fix : The module is now thread safe. You can test if it had been
258 built with thread safety features enabled through the
259 VMG_THREADSAFE constant.
260 + Fix : Correct backtrace when wizard() croaks.
261 + Fix : 'cast $a, undef' should throw an 'invalid wizard' error instead
262 of an 'invalid signature'.
264 0.19 2008-07-05 15:05 UTC
265 + Add : The patchlevel with which the module has been built is now
266 exported with the VMG_PERL_PATCHLEVEL constant.
267 + Chg : Version checking macros overhaul.
268 + Fix : 'uvar' magic should only be enabled in maint-5.10 and higher
269 since it's never going to be backported to 5.8.
270 + Fix : Likewise, the copy callback API change should only be enabled in
272 + Fix : Instead of those ackward fake refcount increments in the wizard
273 destructor, flag the wizard with SVf_BREAK and force temps
274 cleanup. This should fix the wizard destruction for all perls,
275 and solves the leak introduced by the previous solution.
277 0.18 2008-07-04 12:20 UTC
278 + Fix : Enable uvar magic when patchlevel >= 28419.
279 + Fix : Set VMG_COMPAT_ARRAY_PUSH_NOLEN for Windows ActiveState Perl
282 0.17 2008-05-11 09:05 UTC
283 + Fix : 5.8.4 and lower don't have mPUSHi. Gah. Yeah, I know, I should
286 0.16 2008-05-10 22:05 UTC
287 + Add : The samples/copy.pl script.
288 + Chg : The sv_magical() + vmg_mg_magical() combo was simplified into
290 + Tst : t/33-code.t was testing scalars, not code.
291 + Tst : is() and like() are better than ok().
292 + Tst : 100% coverage reached.
294 0.15 2008-04-11 18:25 UTC
295 + Chg : Factor vmg_cb_call{1,2,3}() into one function.
296 + Fix : len magic is no longer called when taking the length() of a
297 magical scalar since p32969. The VMG_COMPAT_SCALAR_LENGTH_NOLEN
298 constant was added to cover this.
299 + Tst : More tests for t/22-len.t.
301 0.14 2008-03-24 12:35 UTC
302 + Fix : t/16-huf.t failures on Solaris and FreeBSD caused by not
303 updating mg->mg_ptr after Renew-ing it on dispell.
304 + Fix : Undefining MGf_DUP caused the wizard's magic to be wrongly
305 initialized. MGf_DUP now appears as true from the user point of
306 view, but the dup callback isn't actually set.
307 + Fix : Warnings with blead due to copy callbacks now taking an I32 (API
309 + Fix : vmg_svt_val() and vmg_uvar_del() aren't required if no uvar
311 + Tst : Tests now output the version of optional modules loaded.
313 0.13 2008-03-19 14:35 UTC
314 + Doc : Link to coverage report.
315 + Fix : Correct dependencies listing in META.yml.
316 + Tst : Improved test coverage.
317 + Tst : Print the patchlevel as a comment.
318 + Tst : Use is() where it's relevant.
319 + Tst : t/16-huf.t now really tests interaction with H::U::FH.
321 0.12 2008-02-07 18:15 UTC
322 + Fix : POD error. Thanks to Chris Williams (BinGOs) for the quick
325 0.11 2008-02-07 17:55 UTC
326 + Add : Copy callbacks now receive the current key/index in $_[2].
327 The current value/element is now in $_[3].
328 + Chg : The trigger of copy magic on list assignment with perls greater
329 than 5.10.0 was caused by uvar magic. Hence,
330 VMG_COMPAT_HASH_LISTASSIGN_COPY was removed. Use VMG_UVAR
332 + Fix : Build failures on patched perls.
333 + Tst : Added missing exported symbols to 01-import.t.
335 0.10 2008-02-04 11:30 UTC
336 + Add : New script : samples/vm_vs_tie.pl, that benchmarks our uvar
337 magic versus tied hashes.
338 + Add : The VMG_COMPAT_* constants can be used from userspace to check
339 perl magic abilities.
340 + Fix : Callbacks that returned undef made us croak, breaking the
341 variable behaviour (regression test in 14-callbacks.t).
342 + Fix : uvar callbacks weren't tested for non-NULL-ity before being
343 called (regression test in 28-uvar.t).
344 + Tst : Fix typo in 25-copy.t that prevented Tie::Hash tests to be ran.
346 0.09 2008-02-02 11:30 UTC
347 + Doc : Explicitely say that uvar callbacks are safely ignored for
349 + Doc : Document caveats and fix the usual set of typos.
350 + Fix : vmg_dispell() didn't check if the ext magic were ours when
351 counting wizards that have uvar callbacks, resulting in a
352 possible memory misread.
353 + Fix : getdata() now returns directly the data object, and no longer a
354 copy. This caused a leak.
355 + Tst : Prefix author tests by 9*-.
356 + Tst : New optional author test : 95-portability-files.t, that uses
357 Test::Portability::Files when it's present.
358 + Tst : New test : 14-self.t, that tests application of magic on the
360 + Tst : Move Hash::Util::FieldHash tests out of 11-multiple.t to
363 0.08 2008-02-01 16:55 UTC
364 + Add : copy magic for tied arrays/hashes.
366 + Add : uvar magics : fetch, store, exists, delete for hashes.
369 Internal development versions.
371 0.06 2007-11-20 10:10 UTC
372 + Chg : 5.7.3 is now officially required.
373 + Fix : "data" test failures on 5.8.{0,2}.
374 + Fix : Drand01() vs rand().
376 0.05 2007-11-19 09:10 UTC
377 + Fix : 5.10.0_RC1 compatibility fix.
379 0.04 2007-08-28 12:25 UTC
380 + Chg : s/require (XSLoader)/use $1/.
381 + Fix : Tests are now strict.
382 + Fix : Complete dependencies.
384 0.03 2007-08-01 17:20 UTC
385 + Add : Passing the signature of an already defined magic to wizard()
386 now returns the corresponding magic object.
387 + Add : You can pass the numeric signature as the wizard argument of
388 cast(), dispell() and getdata().
389 + Add : Any argument specified after the wizard (or the signature) in a
390 call to cast() is now passed to the private data constructor in
392 + Chg : $_[0] is now always a reference to the magic variable in all
393 callbacks. The reason for changing from the previous behaviour
394 is that one may want to apply the same magic to a plain scalar
395 and to a scalar reference, and needs a way to distinguish
396 between them in the callback (say, ref()).
397 + Fix : Wizard object destruction used not to free the signature.
399 0.02 2007-07-27 13:50 UTC
400 + Fix : In response to test report 548152 :
401 Newx() and SvMAGIC_set() not present on older perls.
402 + Fix : In response to test report 548275 :
403 Since perl 5.9.5, 'clear' magic is invoked when an array is
404 undefined (bug #43357). Moreover, 'len' magic is no longer
405 called by pushing an element since perl 5.9.3.
406 + Fix : Missing glob test in MANIFEST.
408 0.01 2007-07-25 16:15 UTC
409 First version, released on an unsuspecting world.
