2
3. Description:
4
5 Version 1.0.5.
6
7 Documented that store() and retrieve() can return undef.
8 That is, the error reporting is not always made via exceptions,
9 as the paragraph on error reporting was implying.
10
11 Auto requires module of blessed ref when STORABLE_thaw misses.
12 When the Storable engine looks for the STORABLE_thaw hook and
13 does not find it, it now tries to require the package into which
14 the blessed reference is.
15
16 Just check $^O, in t/lock.t: there's no need to pull the whole
17 Config module for that.

21. Description:
22
23 Version 1.0.3.
24
25 Avoid using "tainted" and "dirty" since Perl remaps them via
26 cpp (i.e. #define). This is deeply harmful when threading
27 is enabled. This concerned both the context structure and
28 local variable and argument names. Brrr..., scary!

30Thu Sep 28 23:46:39 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
31
32. Description:
33
34 Version 1.0.2.
35
36 Fixed spelling in README.
37
38 Added lock_store, lock_nstore, and lock_retrieve (advisory locking)
39 after a proposal from Erik Haugan <erik@solbors.no>.
40
41 Perls before 5.004_04 lack newSVpvn, added remapping in XS.
42
43 Fixed stupid typo in the t/utf8.t test.
44
45Sun Sep 17 18:51:10 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
46
47. Description:
48
49 Version 1.0.1, binary format 2.3.
50
51 Documented that doubles are stored stringified by nstore().
52
53 Added Salvador Ortiz Garcia in CREDITS section, He identified
54 a bug in the store hooks and proposed the right fix: the class
55 id was allocated too soon. His bug case was also added to
56 the regression test suite.
57
58 Now only taint retrieved data when source was tainted. A bug
59 discovered by Marc Lehmann.
60
61 Added support for UTF-8 strings, a contribution of Marc Lehmann.
62 This is normally only activated in post-5.6 perls.
63
9e21b3d0 64Thu Aug 31 23:06:06 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
65
66 First official release Storable 1.0, for inclusion in perl 5.7.0.
67 The license scheme is now compatible with Perl's.

71. Description:
72
73
74 ANSI-fied most of the code, preparing for Perl core integration.
75 The next version of Storable will be 0.8, and will be integrated
76 into the Perl core (development branch).
77
78 Dispatch tables were moved upfront to relieve some compilers,
79 especially on AIX and Windows platforms.
80
81 Merged 64-bit fixes from perl5-porters.

84
85. Description:
86
87 Added a refcnt dec in retrieve_tied_key(): sv_magic() increases
88 the refcnt on the mg_ptr as well.
89
90 Removed spurious dependency to Devel::Peek, which was used for
91 testing only in t/tied_items.t. Thanks to Conrad Heiney
92 <conrad@fringehead.org> for spotting it first.
93
94Sun Aug 13 22:12:59 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
95
96. Description:
97
98 Marc Lehmann kindly contributed code to add overloading support
99 and to handle references to tied variables.
100
101 Rewrote leading blurb about compatibility to make it clearer what
102 "backward compatibility" is about: when I say 0.7 is backward
103 compatible with 0.6, it means the revision 0.7 can read files
104 produced by 0.6.
105
106 Mention new Clone(3) extension in SEE ALSO.
107
108 Was wrongly optimizing for "undef" values in hashes by not
109 fully recursing: as a result, tied "undef" values were incorrectly
110 serialized.
111
112Sun Jul 30 12:59:17 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
113
114 First revision of Storable 0.7.
115
116 The serializing format is new, known as version 2.0. It is fully
117 backward compatible with 0.6. Earlier formats are deprecated and
118 have not even been tested: next version will drop pre-0.6 format.
119
120 Changes since 0.6@11:
121
122 - Moved interface to the "beta" status. Some tiny parts are still
123 subject to change, but nothing important enough to warrant an "alpha"
124 status any longer.
125
126 - Slightly reduced the size of the Storable image by factorizing
127 object class names and removing final object storage notification due
128 to a redesign of the blessed object storing.
129
130 - Classes can now redefine how they wish their instances to be serialized
131 and/or deep cloned. Serializing hooks are written in Perl code.
132
133 - The engine is now fully re-entrant.
134
135Sun Apr 2 23:47:50 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
136
137. Description:
138
139 Added provision to detect more recent binary formats, since
140 the new upcoming Storable-0.7 will use a different format.
141 In order to prevent attempting the de-serialization of newer
142 formats by older versions, I'm adding this now to the 0.6 series.
143
144 I'm expecting this revision to be the last of the 0.6 series.
145 Unless it does not work with perl 5.6, which I don't use yet,
146 and therefore against which I cannot test.
147
148Wed Mar 29 19:55:21 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
149
150. Description:
151
152 Added note about format incompatibilities with old versions
153 (i.e. pre 0.5@9 formats, which cannot be understood as there
154 was no versionning information in the file by then).
155
156 Protect all $@ variables when eval {} used, to avoid corrupting
157 it when store/retrieve is called within an exception handler.
158
159 Mistakenly included "patchlevel.h" instead of <patchlevel.h>,
160 preventing Perl's patchlevel from being included, which is
161 needed starting from 5.6.
162
163Tue May 12 09:15:15 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
164
165. Description:
166
167 Fixed shared "undef" bug in hashes, which did not remain shared
168 through store/retrieve.
169
170Thu Feb 10 19:48:16 MET 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
171
172. Description:
173
174 added last_op_in_netorder() predicate
175 documented last_op_in_netorder()
176 added tests for the new last_op_in_netorder() predicate
177
178Wed Oct 20 19:07:36 MEST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
179
180. Description:
181
182 Forgot to update VERSION
183
184Tue Oct 19 21:25:02 MEST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
185
186. Description:
187
188 Added mention of japanese translation for the manual page.
189
190 Fixed typo in macro that made threaded code not compilable,
191 especially on Win32 platforms.
192
193 Changed detection of older perls (pre-5.005) by testing PATCHLEVEL
194 directly instead of relying on internal symbols.
195
196Tue Sep 14 22:13:28 MEST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
197
198. Description:
199
200 Integrated "thread-safe" patch from Murray Nesbitt.
201 Note that this may not be very efficient for threaded code,
202 see comment in the code.
203
204 Try to avoid compilation warning on 64-bit CPUs. Can't test it,
205 since I don't have access to such machines.
206
207Mon Jul 12 14:37:19 METDST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
208
209. Description:
210
211 changed my e-mail to pobox.
212
213 mentionned it is not thread-safe.
214
215 updated version number.
216
217 uses new internal PL_* naming convention.
218
219Fri Jul 3 13:38:16 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
220
221. Description:
222
223 Updated benchmark figures due to recent optimizations done in
224 store(): tagnums are now stored as-is in the hash table, so
225 no surrounding SV is created. And the "shared keys" mode for
226 hash table was turned off.
227
228 Fixed backward compatibility (wrt 0.5@9) for retrieval of
229 blessed refs. That old version did something wrong, but the
230 bugfix prevented correct retrieval of the old format.
231
232Mon Jun 22 11:00:48 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
233
234. Description:
235
236 Changed benchmark figures.
237
238 Adjust refcnt of tied objects after calling sv_magic() to avoid
239 memory leaks. Contributed by Jeff Gresham.
240
241Fri Jun 12 11:50:04 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
242
243. Description:
244
245 Added workaround for persistent LVALUE-ness in perl5.004. All
246 scalars tagged as being an lvalue are handled as if they were
247 not an lvalue at all. Added test for that LVALUE bug workaround.
248
249 Now handles Perl immortal scalars explicitely, by storing &sv_yes
250 as such, explicitely.
251
252 Retrieval of non-immortal undef cannot be shared. Previous
253 version was over-optimizing by not creating a separate SV for
254 all undefined scalars seen.
255
256Thu Jun 4 17:21:51 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
257
258. Description:
259
260 Baseline for Storable-0.6@0.
261
262 This version introduces a binary incompatibility in the generated
263 binary image, which is more compact than older ones by approximatively
264 15%, depending on the exact degree of sharing in your structures.
265
266 The good news is that your older images can still be retrieved with
267 this version, i.e. backward compatibility is preserved. This version
268 of Storable can only generate new binaries however.
269
270 Another good news is that the retrieval of data structure is
271 significantly quicker than before, because a Perl array is used
272 instead of a hash table to keep track of retrieved objects, and
273 also because the image being smaller, less I/O function calls are
274 made.
275
276Tue May 12 09:15:15 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
277
278. Description:
279
280 Version number now got from Storable.pm directly.
281
282 Fixed overzealous sv_type() optimization, which would make
283 Storable fail when faced with an "upgraded" SV to the PVIV
284 or PVNV kind containing a reference.
285
286Thu Apr 30 15:11:30 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
287
288. Description:
289
290 Extended the SYNOPSIS section to give quick overview of the
291 routines and their signature.
292
293 Optimized sv_type() to avoid flags checking when not needed, i.e.
294 when their type makes it impossible for them to be refs or tied.
295 This slightly increases throughput by a few percents when refs
296 and tied variables are marginal occurrences in your data.
297
298 Stubs for XS now use OutputStream and InputStream file types to
299 make it work when the given file is actually a socket. Perl
300 makes a distinction for sockets in its internal I/O structures
301 by having both a read and a write structure, whereas plain files
302 share the same one.
303
304Tue Jun 3 09:41:33 METDST 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
305
306. Description:
307
308 Thanks to a contribution from Benjamin A. Holzman, Storable is now
309 able to correctly serialize tied SVs, i.e. tied arrays, hashes
310 and scalars.
311
312Thu Apr 9 18:07:51 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
313
314. Description:
315
316 I said SvPOK() had changed to SvPOKp(), but that was a lie...
317
318Wed Apr 8 13:14:29 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
319
320. Description:
321
322 Wrote sizeof(SV *) instead of sizeof(I32) when portable, which
323 in effect mangled the object tags and prevented portability
324 accross 32/64 bit architectures!
325
326Wed Mar 25 14:57:02 MET 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
327
328. Description:
329
330 Added code example for store_fd() and retrieve_fd() in the
331 man page, to emphasize that file descriptors must be passed as
332 globs, not as plain strings.
333
334 Cannot use SV addresses as tag when using nstore() on LP64. This
335 was the cause of problems when creating a storable image on an
336 LP64 machine and retrieving it on an ILP32 system, which is
337 exactly what nstore() is meant for...
338
339 However, we continue to use SV addresses as tags for plain store(),
340 because benchamarking shows that it saves up to 8% of the store
341 time, and store() is meant to be fast at the expense of lack
342 of portability.
343
344 This means there will be approximately an 8% degradation of
345 performance for nstore(), but it's now working as expected.
346 That cost may vary on your machine of course, since it is
347 solely caused by the memory allocation overhead used to create
348 unique SV tags for each distinct stored SV.
349
350Tue Jan 20 09:21:53 MET 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
351
352. Description:
353
354 Don't use any '_' in version number.
355
356Tue Jan 13 17:51:50 MET 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
357
358. Description:
359
360 Updated version number.
361
362 added binmode() calls for systems where it matters.
363
364 Be sure to pass globs, not plain file strings, to C routines,
365 so that Storable can be used under the Perl debugger.
366
367Wed Nov 5 10:53:22 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
368
369. Description:
370
371 Fix memory leaks on seen hash table and returned SV refs.
372
373 Storable did not work properly when tainting enabled.
374
375 Fixed "Allocation too large" messages in freeze/thaw and added.
376 proper regression test in t/freeze.t.
377
378Tue Jun 3 09:41:33 METDST 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
379
380. Description:
381
382 Updated version number
383
384 Added freeze/thaw interface and dclone.
385
386Fri May 16 10:45:47 METDST 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
387
388. Description:
389
390 Forgot that AutoLoader does not export its own AUTOLOAD.
391 I could use
392
393 use AutoLoader 'AUTOLOAD';
394
395 but that would not be backward compatible. So the export is
396 done by hand...
397
398Tue Mar 25 11:21:32 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
399
400. Description:
401
402 Empty scalar strings are now "defined" at retrieval time.
403
404 New test to ensure an empty string is defined when retrieved.
405
406Thu Feb 27 16:32:44 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
407
408. Description:
409
410 Updated version number
411
412 Declare VERSION as being used
413
414 Fixed a typo in the PerlIO_putc remapping.
415 PerlIO_read and perlIO_write inverted size/nb_items.
416 (only relevant for pre-perl5.004 versions)
417
418Thu Feb 27 15:58:31 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
419
420. Description:

422 Updated version number
423
424 Added VERSION identification
425
426 Allow build with perl5.003, which is ante perlIO time
427

434Wed Jan 22 15:19:56 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
435
436. Description:
437
438 Updated version number in Makefile.PL.
439
440 Added "thanks to" section to README.
441
442 Documented new forgive_me variable.
443
444 Made 64-bit clean.
445
446 Added forgive_me support to allow store() of data structures
447 containing non-storable items like CODE refs.
448
