3 Version 2.11
4
5 1. Storing restricted hashes in canonical order would SEGV. Fixed.
6 2. It was impossible to retrieve references to PL_sv_no and and
7 PL_sv_undef from STORABLE_thaw hooks.
8 3. restrict.t was failing on 5.8.0, due to 5.8.0's unique
9 implementation of restricted hashes using PL_sv_undef
10 4. These changes allow a space optimisation for restricted hashes.

14 Version 2.10
15
16 1. Thread safety: Storable::CLONE/init_perlinterp() now create
17 a new Perl context for each new ithread.
18 (From Stas Bekman and Jan Dubois.)
19 2. Fix a tag count mismatch with $Storable::Deparse that caused
20 all back-references after a stored sub to be off-by-N (where
21 N was the number of code references in between).
22 (From Sam Vilain.)
23 3. Prevent CODE references from turning into SCALAR references.
24 (From Slaven Rezic.)

38 Version 2.08
39
40 This release works around a 5.8.0 bug which caused hashes to not
41 be marked as having key flags even though an HEK had HEK_WASUTF8
42 set. (Note that the only reasonable solution is to silently drop
43 the flag from the affected key.)
44
45 Users of RT 3 who were seeing assertion failures should upgrade.
46 (Perl 5.8.1 will have the bug fixed.)

62 round)
63 Fix t/integer.t initialisation to actually generate 64 bits of 9c
64 Fix comparison tests to use eval to get around 64 bit IV conversion
65 issues on 5.6.x, following my t/integer.t ^ precedence bug found by
66 Rafael Garcia-Suarez

84 Version 2.04
85
86 Bug fix from Radu Greab <radu@netsoft.ro> (plus regression test)
87 to fix a recently introduced bug detected by Dave Rolsky.
88 Bug was that for a non threaded build, the class information was
89 being lost at freeze time on the first object with a STORABLE_freeze
90 hook. Consequentially the object was not blessed at all when thawed.
91 (The presence (or lack) of STORABLE_thaw was irrelevant; this was
92 a store-time data lost bug, caused by failure to initialize internal
93 context)
94 The bug was introduced as development perl change 16442 (on
95 2002/05/07), so has been present since 2.00.
96 Patches to introduce more regression tests to reduce the chance of
97 a reoccurance of this sort of goof are always welcome.

100
8932d55c 101 Version 2.03 Header changes on 5.6.x on Unix where IV is long long
102
103 5.6.x introduced the ability to have IVs as long long. However,
104 Configure still defined BYTEORDER based on the size of a long.
105 Storable uses the BYTEORDER value as part of the header, but
106 doesn't explicity store sizeof(IV) anywhere in the header.
107 Hence on 5.6.x built with IV as long long on a platform that
108 uses Configure (ie most things except VMS and Windows) headers
109 are identical for the different IV sizes, despite the files
110 containing some fields based on sizeof(IV)
111
112 5.8.0 is consistent; all platforms have BYTEORDER in config.h
113 based on sizeof(IV) rather than sizeof(long). This means that
114 the value of BYTEORDER will change from (say) 4321 to 87654321
115 between 5.6.1 and 5.8.0 built with the same options to Configure
116 on the same machine. This means that the Storable header will
117 differ, and the two versions will wrongly thing that they are
118 incompatible.
119
120 For the benefit of long term consistency, Storable now
121 implements the 5.8.0 BYTEORDER policy on 5.6.x. This means that
122 2.03 onwards default to be incompatible with 2.02 and earlier
123 (ie the large 1.0.x installed base) on the same 5.6.x perl.
124
125 To allow interworking, a new variable
126 $Storable::interwork_56_64bit is introduced. It defaults to
127 false. Set it to true to read and write old format files. Don't
128 use it unless you have existing stored data written with 5.6.x
129 that you couldn't otherwise read, or you need to interwork with
130 a machine running older Storable on a 5.6.x with long long IVs
131 (i.e., you probably don't need to use it).

134
25f64a11 135 Version 2.02
136
137 Rewrite Storable.xs so that the file header structure for write_magic
138 is built at compile time, and check_magic attempts to the header in
139 blocks rather than byte per byte. These changes make the compiled
140 extension 2.25% smaller, but are not significant enough to give a
141 noticeable speed up.

144
25f64a11 145 Version 2.01
146
147 - New regression tests integer.t
148 - Add code to safely store large unsigned integers.
149 - Change code not to attempt to store large integers (ie > 32 bits)
150 in network order as 32 bits.
151
152 *Never* underestimate the value of a pathological test suite carefully
153 crafted with maximum malice before writing a line of real code. It
154 prevents crafty bugs from stowing away in your released code.
155 It's much less embarrassing to find them before you ship.
156 (Well, never underestimate it if you ever want to work for me)

159
25f64a11 160 Version 2.0, binary format 2.5 (but writes format 2.4 on pre 5.7.3)
161
162 The perl5 porters have decided to make sure that Storable still
163 builds on pre-5.8 perls, and make the 5.8 version available on CPAN.
164 The VERSION is now 2.0, and it passes all tests on 5.005_03, 5.6.1
165 and 5.6.1 with threads. On 5.6.0 t/downgrade.t fails tests 34 and 37,
166 due to a bug in 5.6.0 - upgrade to 5.6.1.
167
168 Jarkko and I have collated the list of changes the perl5 porters have
169 from the perl5 Changes file:
170
171 - data features of upcoming perl 5.8.0 are supported: Unicode hash
172 keys (Unicode hash values have been supported since Storable 1.0.1)
173 and "restricted hashes" (readonly hashes and hash entries)
174 - a newer version of perl can now be used to serialize data which is
175 not supported in earlier perls: Storable will attempt to do the
176 right thing for as long as possible, croaking only when safe data
177 conversion simply isn't possible. Alternatively earlier perls can
178 opt to have a lossy downgrade data instead of croaking
179 - when built with perls pre 5.7.3 this Storable writes out files
180 with binary format 2.4, the same format as Storable 1.0.8 onwards.
181 This should mean that this Storable will inter-operate seamlessly
182 with any Storable 1.0.8 or newer on perls pre 5.7.3
183 - dclone() now works with empty string scalar objects
184 - retrieving of large hashes is now more efficient
185 - more routines autosplit out of the main module, so Storable should
186 load slightly more quickly
187 - better documentation
188 - the internal context objects are now freed explicitly, rather than
189 relying on thread or process exit
190 - bugs fixed in debugging trace code affecting builds made with 64 bit
191 IVs
192 - code tidy-ups to allow clean compiles with more warning options
193 turned on avoid problems with $@ getting corrupted on 5.005_03 if
194 Carp wasn't already loaded
195 - added &show_file_magic, so you can add to /etc/magic and teach
196 Unix's file command about Storable files
197
198 We plan to keep Storable on CPAN in sync with the Perl core, so
199 if you encounter bugs or other problems building or using Storable,
200 please let us know at perl5-porters@perl.org
201 Patches welcome!

204
25f64a11 205 This is the LAST maintenance release of the Storable module.
206 Indeed, Storable is now part of perl 5.8, and will be maintained
207 as part of Perl. The CPAN module will remain available there
208 for people running pre-5.8 perls.
596596d5 209
25f64a11 210 Avoid requiring Fcntl upfront, useful to embedded runtimes.
211 Use an eval {} for testing, instead of making Storable.pm
212 simply fail its compilation in the BEGIN block.
596596d5 213
25f64a11 214 store_fd() will now correctly autoflush file if needed.

217
25f64a11 218 Fixed truncation race with lock_retrieve() in lock_store().
219 The file has to be truncated only once the exclusive lock is held.
6e0ac6f5 220
25f64a11 221 Removed spurious debugging messages in .xs file.

e993d95c 223Sun Jul 1 13:27:32 MEST 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
224
25f64a11 225 Systematically use "=over 4" for POD linters.
226 Apparently, POD linters are much stricter than would
227 otherwise be needed, but that's OK.
e993d95c 228
25f64a11 229 Fixed memory corruption on croaks during thaw(). Thanks
230 to Claudio Garcia for reproducing this bug and providing the
231 code to exercise it. Added test cases for this bug, adapted
232 from Claudio's code.
e993d95c 233
25f64a11 234 Made code compile cleanly with -Wall (from Jarkko Hietaniemi).
e993d95c 235
25f64a11 236 Changed tagnum and classnum from I32 to IV in context. Also
237 from Jarkko.

240
25f64a11 241 Last version was wrongly compiling with assertions on, due
242 to an edit glitch. That did not cause any problem (apart from
243 a slight performance loss) excepted on Win* platforms, where the
244 assertion code does not compile.

25f64a11 248 Version 1.0.10.
8be2b38b 249
25f64a11 250 Forgot to increase version number at previous patch (there were
251 two of them, which is why we jump from 1.0.8 to 1.0.10).

b12202d0 253Sat Feb 17 13:35:00 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
254
25f64a11 255 Version 1.0.8, binary format 2.4.
b12202d0 256
25f64a11 257 Fixed incorrect error message.
b12202d0 258
25f64a11 259 Now bless objects ASAP at retrieve time, which is meant to fix
260 two bugs:
b12202d0 261
25f64a11 262 * Indirect references to overloaded object were not able to
263 restore overloading if the object was not blessed yet,
264 which was possible since blessing occurred only after the
265 recursive retrieval.
b12202d0 266
25f64a11 267 * Storable hooks asking for serialization of blessed ref could
268 get un-blessed refs at retrieval time, for the very same
269 reason.
b12202d0 270
25f64a11 271 The fix implemented here was suggested by Nick Ing-Simmons.
b12202d0 272
25f64a11 273 Added support for blessed ref to tied structures. This is the
274 cause for the binary format change.
b12202d0 275
25f64a11 276 Added EBCDIC version of the compatibility test with 0.6.11,
277 from Peter Prymmer
b12202d0 278
25f64a11 279 Added tests for the new features, and to make sure the bugs they
280 are meant to fix are indeed fixed.
b12202d0 281
862382c7 282Wed Jan 3 10:43:18 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
283
25f64a11 284 Removed spurious 'clean' entry in Makefile.PL.
862382c7 285
25f64a11 286 Added CAN_FLOCK to determine whether we can flock() or not,
287 by inspecting Perl's configuration parameters, as determined
288 by Configure.
862382c7 289
25f64a11 290 Trace offending package when overloading cannot be restored
291 on a scalar.
862382c7 292
25f64a11 293 Made context cleanup safer to avoid dup freeing, mostly in the
294 presence of repeated exceptions during store/retrieve (which can
295 cause memory leaks anyway, so it's just additional safety, not a
296 definite fix).
862382c7 297

299
25f64a11 300 Version 1.0.6.
90826881 301
25f64a11 302 Fixed severe "object lost" bug for STORABLE_freeze returns,
303 when refs to lexicals, taken within the hook, were to be
304 serialized by Storable. Enhanced the t/recurse.t test to
305 stress hook a little more with refs to lexicals.
90826881 306
212e9bde 307Thu Oct 26 19:14:38 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
308
25f64a11 309 Version 1.0.5.
212e9bde 310
25f64a11 311 Documented that store() and retrieve() can return undef.
312 That is, the error reporting is not always made via exceptions,
313 as the paragraph on error reporting was implying.
212e9bde 314
25f64a11 315 Auto requires module of blessed ref when STORABLE_thaw misses.
316 When the Storable engine looks for the STORABLE_thaw hook and
317 does not find it, it now tries to require the package into which
318 the blessed reference is.
212e9bde 319
25f64a11 320 Just check $^O, in t/lock.t: there's no need to pull the whole
321 Config module for that.
212e9bde 322
8be2b38b 323Mon Oct 23 20:03:49 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
324
25f64a11 325 Version 1.0.4.
8be2b38b 326
25f64a11 327 Protected calls to flock() for DOS platform: apparently, the
328 flock/fcnlt emulation is reported to be broken on that
329 platform.
8be2b38b 330
25f64a11 331 Added logcarp emulation if they don't have Log::Agent, since
332 we now use it to carp when lock_store/lock_retrieve is used
333 on DOS.

dd19458b 335Fri Sep 29 21:52:29 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
336
25f64a11 337 Version 1.0.3.
dd19458b 338
25f64a11 339 Avoid using "tainted" and "dirty" since Perl remaps them via
340 cpp (i.e. #define). This is deeply harmful when threading
341 is enabled. This concerned both the context structure and
342 local variable and argument names. Brrr..., scary!
dd19458b 343
344Thu Sep 28 23:46:39 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
345
25f64a11 346 Version 1.0.2.
dd19458b 347
25f64a11 348 Fixed spelling in README.
dd19458b 349
25f64a11 350 Added lock_store, lock_nstore, and lock_retrieve (advisory locking)
351 after a proposal from Erik Haugan <erik@solbors.no>.
dd19458b 352
25f64a11 353 Perls before 5.004_04 lack newSVpvn, added remapping in XS.
dd19458b 354
25f64a11 355 Fixed stupid typo in the t/utf8.t test.

25f64a11 359 Version 1.0.1, binary format 2.3.
dd19458b 360
25f64a11 361 Documented that doubles are stored stringified by nstore().
dd19458b 362
25f64a11 363 Added Salvador Ortiz Garcia in CREDITS section, He identified
364 a bug in the store hooks and proposed the right fix: the class
365 id was allocated too soon. His bug case was also added to
366 the regression test suite.
dd19458b 367
25f64a11 368 Now only taint retrieved data when source was tainted. A bug
369 discovered by Marc Lehmann.
dd19458b 370
25f64a11 371 Added support for UTF-8 strings, a contribution of Marc Lehmann.
372 This is normally only activated in post-5.6 perls.

25f64a11 381 ANSI-fied most of the code, preparing for Perl core integration.
382 The next version of Storable will be 0.8, and will be integrated
383 into the Perl core (development branch).
f0ffaed8 384
25f64a11 385 Dispatch tables were moved upfront to relieve some compilers,
386 especially on AIX and Windows platforms.

391
25f64a11 392 Added a refcnt dec in retrieve_tied_key(): sv_magic() increases
393 the refcnt on the mg_ptr as well.
7a6a85bf 394
25f64a11 395 Removed spurious dependency to Devel::Peek, which was used for
396 testing only in t/tied_items.t. Thanks to Conrad Heiney
397 <conrad@fringehead.org> for spotting it first.

400
25f64a11 401 Marc Lehmann kindly contributed code to add overloading support
402 and to handle references to tied variables.
7a6a85bf 403
25f64a11 404 Rewrote leading blurb about compatibility to make it clearer what
405 "backward compatibility" is about: when I say 0.7 is backward
406 compatible with 0.6, it means the revision 0.7 can read files
407 produced by 0.6.
7a6a85bf 408
25f64a11 409 Mention new Clone(3) extension in SEE ALSO.
7a6a85bf 410
25f64a11 411 Was wrongly optimizing for "undef" values in hashes by not
412 fully recursing: as a result, tied "undef" values were incorrectly
413 serialized.
7a6a85bf 414
415Sun Jul 30 12:59:17 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
416
25f64a11 417 First revision of Storable 0.7.
7a6a85bf 418
25f64a11 419 The serializing format is new, known as version 2.0. It is fully
420 backward compatible with 0.6. Earlier formats are deprecated and
421 have not even been tested: next version will drop pre-0.6 format.
7a6a85bf 422
25f64a11 423 Changes since 0.6@11:
7a6a85bf 424
25f64a11 425 - Moved interface to the "beta" status. Some tiny parts are still
426 subject to change, but nothing important enough to warrant an "alpha"
427 status any longer.
7a6a85bf 428
25f64a11 429 - Slightly reduced the size of the Storable image by factorizing
430 object class names and removing final object storage notification due
431 to a redesign of the blessed object storing.
7a6a85bf 432
25f64a11 433 - Classes can now redefine how they wish their instances to be serialized
434 and/or deep cloned. Serializing hooks are written in Perl code.
7a6a85bf 435
25f64a11 436 - The engine is now fully re-entrant.

438Sun Apr 2 23:47:50 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
439
25f64a11 440 Added provision to detect more recent binary formats, since
441 the new upcoming Storable-0.7 will use a different format.
442 In order to prevent attempting the de-serialization of newer
443 formats by older versions, I'm adding this now to the 0.6 series.
7a6a85bf 444
25f64a11 445 I'm expecting this revision to be the last of the 0.6 series.
446 Unless it does not work with perl 5.6, which I don't use yet,
447 and therefore against which I cannot test.
7a6a85bf 448
449Wed Mar 29 19:55:21 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
450
25f64a11 451 Added note about format incompatibilities with old versions
452 (i.e. pre 0.5@9 formats, which cannot be understood as there
453 was no versionning information in the file by then).
7a6a85bf 454
25f64a11 455 Protect all $@ variables when eval {} used, to avoid corrupting
456 it when store/retrieve is called within an exception handler.
7a6a85bf 457
25f64a11 458 Mistakenly included "patchlevel.h" instead of <patchlevel.h>,
459 preventing Perl's patchlevel from being included, which is
460 needed starting from 5.6.
7a6a85bf 461
462Tue May 12 09:15:15 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
463
25f64a11 464 Fixed shared "undef" bug in hashes, which did not remain shared
465 through store/retrieve.
7a6a85bf 466
467Thu Feb 10 19:48:16 MET 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
468
25f64a11 469 added last_op_in_netorder() predicate
470 documented last_op_in_netorder()
471 added tests for the new last_op_in_netorder() predicate
7a6a85bf 472
473Wed Oct 20 19:07:36 MEST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>

7a6a85bf 476
477Tue Oct 19 21:25:02 MEST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
478
25f64a11 479 Added mention of japanese translation for the manual page.
7a6a85bf 480
25f64a11 481 Fixed typo in macro that made threaded code not compilable,
482 especially on Win32 platforms.
7a6a85bf 483
25f64a11 484 Changed detection of older perls (pre-5.005) by testing PATCHLEVEL
485 directly instead of relying on internal symbols.
7a6a85bf 486
487Tue Sep 14 22:13:28 MEST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
488
25f64a11 489 Integrated "thread-safe" patch from Murray Nesbitt.
490 Note that this may not be very efficient for threaded code,
491 see comment in the code.
7a6a85bf 492
25f64a11 493 Try to avoid compilation warning on 64-bit CPUs. Can't test it,
494 since I don't have access to such machines.
7a6a85bf 495
496Mon Jul 12 14:37:19 METDST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
497
25f64a11 498 changed my e-mail to pobox.
7a6a85bf 499
25f64a11 500 mentionned it is not thread-safe.
7a6a85bf 501
25f64a11 502 updated version number.
7a6a85bf 503
25f64a11 504 uses new internal PL_* naming convention.
7a6a85bf 505
506Fri Jul 3 13:38:16 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
507
25f64a11 508 Updated benchmark figures due to recent optimizations done in
509 store(): tagnums are now stored as-is in the hash table, so
510 no surrounding SV is created. And the "shared keys" mode for
511 hash table was turned off.
7a6a85bf 512
25f64a11 513 Fixed backward compatibility (wrt 0.5@9) for retrieval of
514 blessed refs. That old version did something wrong, but the
515 bugfix prevented correct retrieval of the old format.
7a6a85bf 516
517Mon Jun 22 11:00:48 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
518
25f64a11 519 Changed benchmark figures.
7a6a85bf 520
25f64a11 521 Adjust refcnt of tied objects after calling sv_magic() to avoid
522 memory leaks. Contributed by Jeff Gresham.
7a6a85bf 523
524Fri Jun 12 11:50:04 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
525
25f64a11 526 Added workaround for persistent LVALUE-ness in perl5.004. All
527 scalars tagged as being an lvalue are handled as if they were
528 not an lvalue at all. Added test for that LVALUE bug workaround.
7a6a85bf 529
25f64a11 530 Now handles Perl immortal scalars explicitely, by storing &sv_yes
531 as such, explicitely.
7a6a85bf 532
25f64a11 533 Retrieval of non-immortal undef cannot be shared. Previous
534 version was over-optimizing by not creating a separate SV for
535 all undefined scalars seen.
7a6a85bf 536
537Thu Jun 4 17:21:51 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
538
25f64a11 539 Baseline for Storable-0.6@0.
7a6a85bf 540
25f64a11 541 This version introduces a binary incompatibility in the generated
542 binary image, which is more compact than older ones by approximatively
543 15%, depending on the exact degree of sharing in your structures.
7a6a85bf 544
25f64a11 545 The good news is that your older images can still be retrieved with
546 this version, i.e. backward compatibility is preserved. This version
547 of Storable can only generate new binaries however.
7a6a85bf 548
25f64a11 549 Another good news is that the retrieval of data structure is
550 significantly quicker than before, because a Perl array is used
551 instead of a hash table to keep track of retrieved objects, and
552 also because the image being smaller, less I/O function calls are
553 made.
7a6a85bf 554
555Tue May 12 09:15:15 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
556
25f64a11 557 Version number now got from Storable.pm directly.
7a6a85bf 558
25f64a11 559 Fixed overzealous sv_type() optimization, which would make
560 Storable fail when faced with an "upgraded" SV to the PVIV
561 or PVNV kind containing a reference.
7a6a85bf 562
563Thu Apr 30 15:11:30 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
564
25f64a11 565 Extended the SYNOPSIS section to give quick overview of the
566 routines and their signature.
7a6a85bf 567
25f64a11 568 Optimized sv_type() to avoid flags checking when not needed, i.e.
569 when their type makes it impossible for them to be refs or tied.
570 This slightly increases throughput by a few percents when refs
571 and tied variables are marginal occurrences in your data.
7a6a85bf 572
25f64a11 573 Stubs for XS now use OutputStream and InputStream file types to
574 make it work when the given file is actually a socket. Perl
575 makes a distinction for sockets in its internal I/O structures
576 by having both a read and a write structure, whereas plain files
577 share the same one.
7a6a85bf 578
579Tue Jun 3 09:41:33 METDST 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
580
25f64a11 581 Thanks to a contribution from Benjamin A. Holzman, Storable is now
582 able to correctly serialize tied SVs, i.e. tied arrays, hashes
583 and scalars.

25f64a11 587 I said SvPOK() had changed to SvPOKp(), but that was a lie...
7a6a85bf 588
589Wed Apr 8 13:14:29 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
590
25f64a11 591 Wrote sizeof(SV *) instead of sizeof(I32) when portable, which
592 in effect mangled the object tags and prevented portability
593 accross 32/64 bit architectures!
7a6a85bf 594
595Wed Mar 25 14:57:02 MET 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
596
25f64a11 597 Added code example for store_fd() and retrieve_fd() in the
598 man page, to emphasize that file descriptors must be passed as
599 globs, not as plain strings.
7a6a85bf 600
25f64a11 601 Cannot use SV addresses as tag when using nstore() on LP64. This
602 was the cause of problems when creating a storable image on an
603 LP64 machine and retrieving it on an ILP32 system, which is
604 exactly what nstore() is meant for...
7a6a85bf 605
25f64a11 606 However, we continue to use SV addresses as tags for plain store(),
607 because benchamarking shows that it saves up to 8% of the store
608 time, and store() is meant to be fast at the expense of lack
609 of portability.
7a6a85bf 610
25f64a11 611 This means there will be approximately an 8% degradation of
612 performance for nstore(), but it's now working as expected.
613 That cost may vary on your machine of course, since it is
614 solely caused by the memory allocation overhead used to create
615 unique SV tags for each distinct stored SV.

25f64a11 623 Updated version number.
7a6a85bf 624
25f64a11 625 added binmode() calls for systems where it matters.
7a6a85bf 626
25f64a11 627 Be sure to pass globs, not plain file strings, to C routines,
628 so that Storable can be used under the Perl debugger.
7a6a85bf 629
630Wed Nov 5 10:53:22 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
631
25f64a11 632 Fix memory leaks on seen hash table and returned SV refs.
7a6a85bf 633
25f64a11 634 Storable did not work properly when tainting enabled.
7a6a85bf 635
25f64a11 636 Fixed "Allocation too large" messages in freeze/thaw and added.
637 proper regression test in t/freeze.t.

25f64a11 647 Forgot that AutoLoader does not export its own AUTOLOAD.
648 I could use
7a6a85bf 649
25f64a11 650 use AutoLoader 'AUTOLOAD';
651
652 but that would not be backward compatible. So the export is
653 done by hand...

25f64a11 659 New test to ensure an empty string is defined when retrieved.
