1 Revision history for Variable-Magic
3 0.38 2009-10-04 16:10 UTC
4 + Dep : All the signature-related features are DEPRECATED and will be
5 removed in december 2009. This includes the 'sig' option to
6 wizard(), the getsig() and gensig() functions, and the SIG_*
8 Afaik those features were never used in real life, and they make
9 the XS code slow and brittle. If you want your wizards to be
10 globally available, you'll have to handle that yourself by
11 storing them in a hash.
12 + Doc : More examples in a new COOKBOOK section.
13 + Fix : Compatiblity with the 5.11.0 release. The new compatibility
14 constant VMG_COMPAT_ARRAY_PUSH_NOLEN_VOID was added to cover
16 + Fix : Work around Kwalitee test misfailures.
18 0.37 2009-08-25 15:25 UTC
19 + Add : The new constant VMG_FORKSAFE can be tested to know whether the
20 module will behave nicely when fork()ing. It's currently always
21 true except on Windows where you need perl 5.10.1 for it to be
23 + Doc : Nits and clarifications.
25 0.36 2009-07-05 16:30 UTC
26 + Chg : getdata() now returns an empty list when no magic is present.
27 It used to return undef but did not croak as stated in the doc.
28 Thanks Matt S. Trout for pointing this out.
29 + Fix : Building and tests with ActiveState Perl 5.8 build >= 822.
31 0.35 2009-05-15 20:50 UTC
32 This is a maintenance release. Users of 0.34 can skip this update.
33 + Chg : uvar magic used to be enabled for 5.9.5. It now requires 5.10 or
35 + Fix : Silence compilation warnings for cxinc().
36 + Rem : The workaround introduced in 0.31 for the "Unknown errors" issue
37 was removed, as regression tests show that 0.34 provides a
39 + Tst : Skip t/40-threads.t on 5.8.x with old versions of threads and
42 0.34 2009-04-19 16:55 UTC
43 + Fix : Destruction of wizards in require.
44 + Fix : "panic: restartop" in 5.10 when dieing at compile time triggers
47 0.33 2009-03-26 00:00 UTC
48 + Chg : cast() and getsig() now croak too when an invalid signature is
50 + Fix : It was possible to generate with gensig() the same signature
51 twice before actually defining the wizards.
52 + Tst : More stash tests.
53 + Tst : Test when the magic takes place in some cases.
54 + Tst : Improved coverage for the op object feature.
56 0.32 2009-03-01 13:45 UTC
57 + Chg : dispell() and getdata() now croak when an invalid signature is
59 + Doc : More examples and a brand new synopsis.
60 + Fix : The signature is no longer stored in the mg_private member of
61 the MAGIC struct. This fixes possible clashes with magics from
63 + Fix : op info objects weren't blessed into the right class.
64 + Fix : Races when initializing the op names cache under threads.
66 0.31 2009-02-19 23:50 UTC
67 + Doc : A somewhat better introduction. The FUNCTION section was moved
68 before CONSTANTS and HISTORY since it's more important. And
69 'assignation' is really 'assignment', says Ricardo. :)
70 + Fix : The op_info features are now thread safe.
71 + Fix : Segfaults that occured when trying to get the op name during
73 + Fix : Segfaults and wrong "Unknown error" exceptions that happened
74 when dieing in require caused a free callback to fire.
75 Thanks Florian Ragwitz for reporting.
77 0.30 2009-02-12 17:05 UTC
78 + Add : You can now get in all the callbacks either the name or a B::OP
79 object representing the current op if you pass the new 'op_info'
80 option to wizard() with respective values VMG_OP_INFO_NAME and
82 + Doc : Document magic on array/hashes values.
83 + Fix : Completely skip free callbacks during global destruction.
84 + Tst : Tests now pass again on 5.8.3 and lower (they were broken since
86 + Tst : Test magic on symbol table and on array/hash values.
88 0.29 2009-02-08 11:10 UTC
89 + Add : Set $_[2] to the default length for len magic on scalars.
90 + Chg : Perl 5.8 is required.
91 + Chg : The CLONE method will no longer be defined for non-threaded
94 + Fix : The logic for turning off the GMAGICAL flag on hashes when no
95 uvar magic is involved could do nasty things on tied hashes.
96 + Upd : More resources in META.yml.
98 0.28 2009-01-24 17:05 UTC
99 + Add : The 'copy_key' option to wizard(), that enables the safe edition
100 of $_[2] in uvar callbacks to redirect actions to another key.
101 + Fix : Exception objects thrown from callbacks at compile time were not
103 + Fix : free callbacks triggered during global destruction could lead to
104 segfaults because the wizard was already freed.
105 + Fix : Refcount of scalars with free callback.
106 + Fix : Segfaults when using get or uvar magic simultaneously with clear
108 + Doc : The documentation about what the callbacks take and should
109 return is now somewhat clearer.
111 0.27 2009-01-18 23:40 UTC
112 + Fix : Offset of 1 with len magic on scalars.
113 + Fix : Segfaults that seem to happen when one croak in a callback at
114 compile time (thanks Ash Berlin for the testcase).
115 + Upd : Resources in META.yml (Florian Ragwitz)
116 + Tst : Large cleanup resulting in a wider set of tested behaviours.
118 0.26 2008-11-29 22:05 UTC
119 + Fix : Leaks of cloned coderefs that access lexicals.
120 + Fix : Building with maint-5.8 and blead (thanks Andreas Koenig).
122 0.25 2008-11-12 19:40 UTC
123 + Fix : Compatibility with 5.8.9.
124 + Fix : Old Pod::Coverage don't ignore CLONE.
125 + Upd : META.yml spec updated to 1.4.
127 0.24 2008-10-12 14:55 UTC
128 + Fix : Really fix it.
130 0.23 2008-10-11 17:25 UTC
131 + Fix : Building on perls with multiplicity but not ithreads.
133 0.22 2008-09-29 19:40 UTC
134 + Doc : Explain how magic differs from overloading.
135 + Fix : Disable thread safety for perl 5.8 on Windows. If you want it
136 enabled, reliable feedback is welcome.
138 0.21_02 2008-09-28 23:10 UTC
139 + Fix : Hide previously deleted magic tokens in vmg_svt_free (Yuval
142 0.21_01 2008-09-22 13:25 UTC
143 + Chg : Shrink the context data.
144 + Fix : Enable thread safety features for perls that just lack
146 + Tst : Output threads and threads::shared versions in threads tests.
148 0.20 2008-09-20 23:35 UTC
149 + Fix : The module is now thread safe. You can test if it had been
150 built with thread safety features enabled through the
151 VMG_THREADSAFE constant.
152 + Fix : Correct backtrace when wizard() croaks.
153 + Fix : 'cast $a, undef' should throw an 'invalid wizard' error instead
154 of an 'invalid signature'.
156 0.19 2008-07-05 15:05 UTC
157 + Add : The patchlevel with which the module has been built is now
158 exported with the VMG_PERL_PATCHLEVEL constant.
159 + Chg : Version checking macros overhaul.
160 + Fix : 'uvar' magic should only be enabled in maint-5.10 and higher
161 since it's never going to be backported to 5.8.
162 + Fix : Likewise, the copy callback API change should only be enabled in
164 + Fix : Instead of those ackward fake refcount increments in the wizard
165 destructor, flag the wizard with SVf_BREAK and force temps
166 cleanup. This should fix the wizard destruction for all perls,
167 and solves the leak introduced by the previous solution.
169 0.18 2008-07-04 12:20 UTC
170 + Fix : Enable uvar magic when patchlevel >= 28419.
171 + Fix : Set VMG_COMPAT_ARRAY_PUSH_NOLEN for Windows ActiveState Perl
174 0.17 2008-05-11 09:05 UTC
175 + Fix : 5.8.4 and lower don't have mPUSHi. Gah. Yeah, I know, I should
178 0.16 2008-05-10 22:05 UTC
179 + Add : The samples/copy.pl script.
180 + Chg : The sv_magical() + vmg_mg_magical() combo was simplified into
182 + Tst : t/33-code.t was testing scalars, not code.
183 + Tst : is() and like() are better than ok().
184 + Tst : 100% coverage reached.
186 0.15 2008-04-11 18:25 UTC
187 + Chg : Factor vmg_cb_call{1,2,3}() into one function.
188 + Fix : len magic is no longer called when taking the length() of a
189 magical scalar since p32969. The VMG_COMPAT_SCALAR_LENGTH_NOLEN
190 constant was added to cover this.
191 + Tst : More tests for t/22-len.t.
193 0.14 2008-03-24 12:35 UTC
194 + Fix : t/16-huf.t failures on Solaris and FreeBSD caused by not
195 updating mg->mg_ptr after Renew-ing it on dispell.
196 + Fix : Undefining MGf_DUP caused the wizard's magic to be wrongly
197 initialized. MGf_DUP now appears as true from the user point of
198 view, but the dup callback isn't actually set.
199 + Fix : Warnings with blead due to copy callbacks now taking an I32 (API
201 + Fix : vmg_svt_val() and vmg_uvar_del() aren't required if no uvar
203 + Tst : Tests now output the version of optional modules loaded.
205 0.13 2008-03-19 14:35 UTC
206 + Doc : Link to coverage report.
207 + Fix : Correct dependencies listing in META.yml.
208 + Tst : Improved test coverage.
209 + Tst : Print the patchlevel as a comment.
210 + Tst : Use is() where it's relevant.
211 + Tst : t/16-huf.t now really tests interaction with H::U::FH.
213 0.12 2008-02-07 18:15 UTC
214 + Fix : POD error. Thanks to Chris Williams (BinGOs) for the quick
217 0.11 2008-02-07 17:55 UTC
218 + Add : Copy callbacks now receive the current key/index in $_[2].
219 The current value/element is now in $_[3].
220 + Chg : The trigger of copy magic on list assignment with perls greater
221 than 5.10.0 was caused by uvar magic. Hence,
222 VMG_COMPAT_HASH_LISTASSIGN_COPY was removed. Use VMG_UVAR
224 + Fix : Build failures on patched perls.
225 + Tst : Added missing exported symbols to 01-import.t.
227 0.10 2008-02-04 11:30 UTC
228 + Add : New script : samples/vm_vs_tie.pl, that benchmarks our uvar
229 magic versus tied hashes.
230 + Add : The VMG_COMPAT_* constants can be used from userspace to check
231 perl magic abilities.
232 + Fix : Callbacks that returned undef made us croak, breaking the
233 variable behaviour (regression test in 14-callbacks.t).
234 + Fix : uvar callbacks weren't tested for non-NULL-ity before being
235 called (regression test in 28-uvar.t).
236 + Tst : Fix typo in 25-copy.t that prevented Tie::Hash tests to be ran.
238 0.09 2008-02-02 11:30 UTC
239 + Doc : Explicitely say that uvar callbacks are safely ignored for
241 + Doc : Document caveats and fix the usual set of typos.
242 + Fix : vmg_dispell() didn't check if the ext magic were ours when
243 counting wizards that have uvar callbacks, resulting in a
244 possible memory misread.
245 + Fix : getdata() now returns directly the data object, and no longer a
246 copy. This caused a leak.
247 + Tst : Prefix author tests by 9*-.
248 + Tst : New optional author test : 95-portability-files.t, that uses
249 Test::Portability::Files when it's present.
250 + Tst : New test : 14-self.t, that tests application of magic on the
252 + Tst : Move Hash::Util::FieldHash tests out of 11-multiple.t to
255 0.08 2008-02-01 16:55 UTC
256 + Add : copy magic for tied arrays/hashes.
258 + Add : uvar magics : fetch, store, exists, delete for hashes.
261 Internal development versions.
263 0.06 2007-11-20 10:10 UTC
264 + Chg : 5.7.3 is now officially required.
265 + Fix : "data" test failures on 5.8.{0,2}.
266 + Fix : Drand01() vs rand().
268 0.05 2007-11-19 09:10 UTC
269 + Fix : 5.10.0_RC1 compatibility fix.
271 0.04 2007-08-28 12:25 UTC
272 + Chg : s/require (XSLoader)/use $1/.
273 + Fix : Tests are now strict.
274 + Fix : Complete dependencies.
276 0.03 2007-08-01 17:20 UTC
277 + Add : Passing the signature of an already defined magic to wizard()
278 now returns the corresponding magic object.
279 + Add : You can pass the numeric signature as the wizard argument of
280 cast(), dispell() and getdata().
281 + Add : Any argument specified after the wizard (or the signature) in a
282 call to cast() is now passed to the private data constructor in
284 + Chg : $_[0] is now always a reference to the magic variable in all
285 callbacks. The reason for changing from the previous behaviour
286 is that one may want to apply the same magic to a plain scalar
287 and to a scalar reference, and needs a way to distinguish
288 between them in the callback (say, ref()).
289 + Fix : Wizard object destruction used not to free the signature.
291 0.02 2007-07-27 13:50 UTC
292 + Fix : In response to test report 548152 :
293 Newx() and SvMAGIC_set() not present on older perls.
294 + Fix : In response to test report 548275 :
295 Since perl 5.9.5, 'clear' magic is invoked when an array is
296 undefined (bug #43357). Moreover, 'len' magic is no longer
297 called by pushing an element since perl 5.9.3.
298 + Fix : Missing glob test in MANIFEST.
300 0.01 2007-07-25 16:15 UTC
301 First version, released on an unsuspecting world.
