1 Revision history for Variable-Magic
3 0.36 2009-07-05 16:30 UTC
4 + Chg : getdata() now returns an empty list when no magic is present.
5 It used to return undef but did not croak as stated in the doc.
6 Thanks Matt S. Trout for pointing this out.
7 + Fix : Building and tests with ActiveState Perl 5.8 build >= 822.
9 0.35 2009-05-15 20:50 UTC
10 This is a maintenance release. Users of 0.34 can skip this update.
11 + Chg : uvar magic used to be enabled for 5.9.5. It now requires 5.10 or
13 + Fix : Silence compilation warnings for cxinc().
14 + Rem : The workaround introduced in 0.31 for the "Unknown errors" issue
15 was removed, as regression tests show that 0.34 provides a
17 + Tst : Skip t/40-threads.t on 5.8.x with old versions of threads and
20 0.34 2009-04-19 16:55 UTC
21 + Fix : Destruction of wizards in require.
22 + Fix : "panic: restartop" in 5.10 when dieing at compile time triggers
25 0.33 2009-03-26 00:00 UTC
26 + Chg : cast() and getsig() now croak too when an invalid signature is
28 + Fix : It was possible to generate with gensig() the same signature
29 twice before actually defining the wizards.
30 + Tst : More stash tests.
31 + Tst : Test when the magic takes place in some cases.
32 + Tst : Improved coverage for the op object feature.
34 0.32 2009-03-01 13:45 UTC
35 + Chg : dispell() and getdata() now croak when an invalid signature is
37 + Doc : More examples and a brand new synopsis.
38 + Fix : The signature is no longer stored in the mg_private member of
39 the MAGIC struct. This fixes possible clashes with magics from
41 + Fix : op info objects weren't blessed into the right class.
42 + Fix : Races when initializing the op names cache under threads.
44 0.31 2009-02-19 23:50 UTC
45 + Doc : A somewhat better introduction. The FUNCTION section was moved
46 before CONSTANTS and HISTORY since it's more important. And
47 'assignation' is really 'assignment', says Ricardo. :)
48 + Fix : The op_info features are now thread safe.
49 + Fix : Segfaults that occured when trying to get the op name during
51 + Fix : Segfaults and wrong "Unknown error" exceptions that happened
52 when dieing in require caused a free callback to fire.
53 Thanks Florian Ragwitz for reporting.
55 0.30 2009-02-12 17:05 UTC
56 + Add : You can now get in all the callbacks either the name or a B::OP
57 object representing the current op if you pass the new 'op_info'
58 option to wizard() with respective values VMG_OP_INFO_NAME and
60 + Doc : Document magic on array/hashes values.
61 + Fix : Completely skip free callbacks during global destruction.
62 + Tst : Tests now pass again on 5.8.3 and lower (they were broken since
64 + Tst : Test magic on symbol table and on array/hash values.
66 0.29 2009-02-08 11:10 UTC
67 + Add : Set $_[2] to the default length for len magic on scalars.
68 + Chg : Perl 5.8 is required.
69 + Chg : The CLONE method will no longer be defined for non-threaded
72 + Fix : The logic for turning off the GMAGICAL flag on hashes when no
73 uvar magic is involved could do nasty things on tied hashes.
74 + Upd : More resources in META.yml.
76 0.28 2009-01-24 17:05 UTC
77 + Add : The 'copy_key' option to wizard(), that enables the safe edition
78 of $_[2] in uvar callbacks to redirect actions to another key.
79 + Fix : Exception objects thrown from callbacks at compile time were not
81 + Fix : free callbacks triggered during global destruction could lead to
82 segfaults because the wizard was already freed.
83 + Fix : Refcount of scalars with free callback.
84 + Fix : Segfaults when using get or uvar magic simultaneously with clear
86 + Doc : The documentation about what the callbacks take and should
87 return is now somewhat clearer.
89 0.27 2009-01-18 23:40 UTC
90 + Fix : Offset of 1 with len magic on scalars.
91 + Fix : Segfaults that seem to happen when one croak in a callback at
92 compile time (thanks Ash Berlin for the testcase).
93 + Upd : Resources in META.yml (Florian Ragwitz)
94 + Tst : Large cleanup resulting in a wider set of tested behaviours.
96 0.26 2008-11-29 22:05 UTC
97 + Fix : Leaks of cloned coderefs that access lexicals.
98 + Fix : Building with maint-5.8 and blead (thanks Andreas Koenig).
100 0.25 2008-11-12 19:40 UTC
101 + Fix : Compatibility with 5.8.9.
102 + Fix : Old Pod::Coverage don't ignore CLONE.
103 + Upd : META.yml spec updated to 1.4.
105 0.24 2008-10-12 14:55 UTC
106 + Fix : Really fix it.
108 0.23 2008-10-11 17:25 UTC
109 + Fix : Building on perls with multiplicity but not ithreads.
111 0.22 2008-09-29 19:40 UTC
112 + Doc : Explain how magic differs from overloading.
113 + Fix : Disable thread safety for perl 5.8 on Windows. If you want it
114 enabled, reliable feedback is welcome.
116 0.21_02 2008-09-28 23:10 UTC
117 + Fix : Hide previously deleted magic tokens in vmg_svt_free (Yuval
120 0.21_01 2008-09-22 13:25 UTC
121 + Chg : Shrink the context data.
122 + Fix : Enable thread safety features for perls that just lack
124 + Tst : Output threads and threads::shared versions in threads tests.
126 0.20 2008-09-20 23:35 UTC
127 + Fix : The module is now thread safe. You can test if it had been
128 built with thread safety features enabled through the
129 VMG_THREADSAFE constant.
130 + Fix : Correct backtrace when wizard() croaks.
131 + Fix : 'cast $a, undef' should throw an 'invalid wizard' error instead
132 of an 'invalid signature'.
134 0.19 2008-07-05 15:05 UTC
135 + Add : The patchlevel with which the module has been built is now
136 exported with the VMG_PERL_PATCHLEVEL constant.
137 + Chg : Version checking macros overhaul.
138 + Fix : 'uvar' magic should only be enabled in maint-5.10 and higher
139 since it's never going to be backported to 5.8.
140 + Fix : Likewise, the copy callback API change should only be enabled in
142 + Fix : Instead of those ackward fake refcount increments in the wizard
143 destructor, flag the wizard with SVf_BREAK and force temps
144 cleanup. This should fix the wizard destruction for all perls,
145 and solves the leak introduced by the previous solution.
147 0.18 2008-07-04 12:20 UTC
148 + Fix : Enable uvar magic when patchlevel >= 28419.
149 + Fix : Set VMG_COMPAT_ARRAY_PUSH_NOLEN for Windows ActiveState Perl
152 0.17 2008-05-11 09:05 UTC
153 + Fix : 5.8.4 and lower don't have mPUSHi. Gah. Yeah, I know, I should
156 0.16 2008-05-10 22:05 UTC
157 + Add : The samples/copy.pl script.
158 + Chg : The sv_magical() + vmg_mg_magical() combo was simplified into
160 + Tst : t/33-code.t was testing scalars, not code.
161 + Tst : is() and like() are better than ok().
162 + Tst : 100% coverage reached.
164 0.15 2008-04-11 18:25 UTC
165 + Chg : Factor vmg_cb_call{1,2,3}() into one function.
166 + Fix : len magic is no longer called when taking the length() of a
167 magical scalar since p32969. The VMG_COMPAT_SCALAR_LENGTH_NOLEN
168 constant was added to cover this.
169 + Tst : More tests for t/22-len.t.
171 0.14 2008-03-24 12:35 UTC
172 + Fix : t/16-huf.t failures on Solaris and FreeBSD caused by not
173 updating mg->mg_ptr after Renew-ing it on dispell.
174 + Fix : Undefining MGf_DUP caused the wizard's magic to be wrongly
175 initialized. MGf_DUP now appears as true from the user point of
176 view, but the dup callback isn't actually set.
177 + Fix : Warnings with blead due to copy callbacks now taking an I32 (API
179 + Fix : vmg_svt_val() and vmg_uvar_del() aren't required if no uvar
181 + Tst : Tests now output the version of optional modules loaded.
183 0.13 2008-03-19 14:35 UTC
184 + Doc : Link to coverage report.
185 + Fix : Correct dependencies listing in META.yml.
186 + Tst : Improved test coverage.
187 + Tst : Print the patchlevel as a comment.
188 + Tst : Use is() where it's relevant.
189 + Tst : t/16-huf.t now really tests interaction with H::U::FH.
191 0.12 2008-02-07 18:15 UTC
192 + Fix : POD error. Thanks to Chris Williams (BinGOs) for the quick
195 0.11 2008-02-07 17:55 UTC
196 + Add : Copy callbacks now receive the current key/index in $_[2].
197 The current value/element is now in $_[3].
198 + Chg : The trigger of copy magic on list assignment with perls greater
199 than 5.10.0 was caused by uvar magic. Hence,
200 VMG_COMPAT_HASH_LISTASSIGN_COPY was removed. Use VMG_UVAR
202 + Fix : Build failures on patched perls.
203 + Tst : Added missing exported symbols to 01-import.t.
205 0.10 2008-02-04 11:30 UTC
206 + Add : New script : samples/vm_vs_tie.pl, that benchmarks our uvar
207 magic versus tied hashes.
208 + Add : The VMG_COMPAT_* constants can be used from userspace to check
209 perl magic abilities.
210 + Fix : Callbacks that returned undef made us croak, breaking the
211 variable behaviour (regression test in 14-callbacks.t).
212 + Fix : uvar callbacks weren't tested for non-NULL-ity before being
213 called (regression test in 28-uvar.t).
214 + Tst : Fix typo in 25-copy.t that prevented Tie::Hash tests to be ran.
216 0.09 2008-02-02 11:30 UTC
217 + Doc : Explicitely say that uvar callbacks are safely ignored for
219 + Doc : Document caveats and fix the usual set of typos.
220 + Fix : vmg_dispell() didn't check if the ext magic were ours when
221 counting wizards that have uvar callbacks, resulting in a
222 possible memory misread.
223 + Fix : getdata() now returns directly the data object, and no longer a
224 copy. This caused a leak.
225 + Tst : Prefix author tests by 9*-.
226 + Tst : New optional author test : 95-portability-files.t, that uses
227 Test::Portability::Files when it's present.
228 + Tst : New test : 14-self.t, that tests application of magic on the
230 + Tst : Move Hash::Util::FieldHash tests out of 11-multiple.t to
233 0.08 2008-02-01 16:55 UTC
234 + Add : copy magic for tied arrays/hashes.
236 + Add : uvar magics : fetch, store, exists, delete for hashes.
239 Internal development versions.
241 0.06 2007-11-20 10:10 UTC
242 + Chg : 5.7.3 is now officially required.
243 + Fix : "data" test failures on 5.8.{0,2}.
244 + Fix : Drand01() vs rand().
246 0.05 2007-11-19 09:10 UTC
247 + Fix : 5.10.0_RC1 compatibility fix.
249 0.04 2007-08-28 12:25 UTC
250 + Chg : s/require (XSLoader)/use $1/.
251 + Fix : Tests are now strict.
252 + Fix : Complete dependencies.
254 0.03 2007-08-01 17:20 UTC
255 + Add : Passing the signature of an already defined magic to wizard()
256 now returns the corresponding magic object.
257 + Add : You can pass the numeric signature as the wizard argument of
258 cast(), dispell() and getdata().
259 + Add : Any argument specified after the wizard (or the signature) in a
260 call to cast() is now passed to the private data constructor in
262 + Chg : $_[0] is now always a reference to the magic variable in all
263 callbacks. The reason for changing from the previous behaviour
264 is that one may want to apply the same magic to a plain scalar
265 and to a scalar reference, and needs a way to distinguish
266 between them in the callback (say, ref()).
267 + Fix : Wizard object destruction used not to free the signature.
269 0.02 2007-07-27 13:50 UTC
270 + Fix : In response to test report 548152 :
271 Newx() and SvMAGIC_set() not present on older perls.
272 + Fix : In response to test report 548275 :
273 Since perl 5.9.5, 'clear' magic is invoked when an array is
274 undefined (bug #43357). Moreover, 'len' magic is no longer
275 called by pushing an element since perl 5.9.3.
276 + Fix : Missing glob test in MANIFEST.
278 0.01 2007-07-25 16:15 UTC
279 First version, released on an unsuspecting world.
