63 Sat Mar 31 06:11:06 IST 2007 Abhijit Menon-Sen <ams@toroid.org>
67 1. Fixes to Storable::dclone, read_magic, retrieve_lscalar
68 2. Storable 0.1 compatibility
69 3. Miscellaneous compile/leak/test/portability fixes
71 Mon May 23 22:48:49 IST 2005 Abhijit Menon-Sen <ams@wiw.org>
75 Minor changes to address a couple of compile problems.
77 Mon Apr 25 07:29:14 IST 2005 Abhijit Menon-Sen <ams@wiw.org>
81 1. Store weak references
82 2. Add STORABLE_attach hook.
84 Thu Jun 17 12:26:43 BST 2004 Nicholas Clark <nick@ccl4.org>
88 1. Don't change the type of top level overloaded references to RV -
89 they are perfectly correct as PVMG
90 2. Storable needs to cope with incoming frozen data that happens to be
93 Wed Mar 17 15:40:29 GMT 2004 Nicholas Clark <nick@ccl4.org>
97 1. Add regression tests for the auto-require of STORABLE_thaw
98 2. Add auto-require of modules to restore overloading (and tests)
99 3. Change to no context (should give speedup with ithreads)
101 Sat Mar 13 20:11:03 GMT 2004 Nicholas Clark <nick@ccl4.org>
105 1. Storing restricted hashes in canonical order would SEGV. Fixed.
106 2. It was impossible to retrieve references to PL_sv_no and and
107 PL_sv_undef from STORABLE_thaw hooks.
108 3. restrict.t was failing on 5.8.0, due to 5.8.0's unique
109 implementation of restricted hashes using PL_sv_undef
110 4. These changes allow a space optimisation for restricted hashes.
112 Sat Jan 24 16:22:32 IST 2004 Abhijit Menon-Sen <ams@wiw.org>
116 1. Thread safety: Storable::CLONE/init_perlinterp() now create
117 a new Perl context for each new ithread.
118 (From Stas Bekman and Jan Dubois.)
119 2. Fix a tag count mismatch with $Storable::Deparse that caused
120 all back-references after a stored sub to be off-by-N (where
121 N was the number of code references in between).
123 3. Prevent CODE references from turning into SCALAR references.
126 Sat Jan 3 18:49:18 GMT 2004 Nicholas Clark <nick@ccl4.org>
130 Fix minor problems with the CPAN release
131 1: Make Storable.xs work on 5.8.2 and later (already in the core)
132 2: Ship the linux hints file
133 3: Ship Test::More for the benefit of Perls pre 5.6.2
134 4: Correct Makefile.PL to only install in core for 5.8.0 and later
136 Sat Sep 6 01:08:20 IST 2003 Abhijit Menon-Sen <ams@wiw.org>
140 This release works around a 5.8.0 bug which caused hashes to not
141 be marked as having key flags even though an HEK had HEK_WASUTF8
142 set. (Note that the only reasonable solution is to silently drop
143 the flag from the affected key.)
145 Users of RT 3 who were seeing assertion failures should upgrade.
146 (Perl 5.8.1 will have the bug fixed.)
148 Mon May 5 10:24:16 IST 2003 Abhijit Menon-Sen <ams@wiw.org>
152 Minor bugfixes (self-tied objects are now correctly stored, as
153 are the results of additions larger than INT_MAX).
155 Mon Oct 7 21:56:38 BST 2002 Nicholas Clark <nick@ccl4.org>
159 Remove qr// from t/downgrade.t so that it will run on 5.004
160 Mention $File::Spec::VERSION a second time in t/forgive.t so that it
161 runs without warnings in 5.004 (this may be a 5.00405 bug I'm working
163 Fix t/integer.t initialisation to actually generate 64 bits of 9c
164 Fix comparison tests to use eval to get around 64 bit IV conversion
165 issues on 5.6.x, following my t/integer.t ^ precedence bug found by
167 Alter t/malice.t to work with Test/More.pm in t/, and skip individual
168 subtests that use $Config{ptrsize}, so that the rest of the test can
169 now be run with 5.004
170 Change t/malice.t and the error message in check_magic in Storable.xs
171 from "Pointer integer size" to "Pointer size"
172 Remove prerequisite of Test::More from Makefile.PL
173 Ship Test::Builder, Test::Simple and Test::More in t

179 Adds support for CODE references from Slaven Rezic
180 <slaven.rezic@berlin.de>.
182 Fri Jun 7 23:55:41 BST 2002 Nicholas Clark
186 Bug fix from Radu Greab <radu@netsoft.ro> (plus regression test)
187 to fix a recently introduced bug detected by Dave Rolsky.
188 Bug was that for a non threaded build, the class information was
189 being lost at freeze time on the first object with a STORABLE_freeze
190 hook. Consequentially the object was not blessed at all when thawed.
191 (The presence (or lack) of STORABLE_thaw was irrelevant; this was
192 a store-time data lost bug, caused by failure to initialize internal
194 The bug was introduced as development perl change 16442 (on
195 2002/05/07), so has been present since 2.00.
196 Patches to introduce more regression tests to reduce the chance of
197 a reoccurence of this sort of goof are always welcome.
199 Thu May 30 20:31:08 BST 2002 Nicholas Clark <nick@ccl4.org>
201 Version 2.03 Header changes on 5.6.x on Unix where IV is long long
203 5.6.x introduced the ability to have IVs as long long. However,
204 Configure still defined BYTEORDER based on the size of a long.
205 Storable uses the BYTEORDER value as part of the header, but
206 doesn't explicitly store sizeof(IV) anywhere in the header.
207 Hence on 5.6.x built with IV as long long on a platform that
208 uses Configure (ie most things except VMS and Windows) headers
209 are identical for the different IV sizes, despite the files
210 containing some fields based on sizeof(IV)
212 5.8.0 is consistent; all platforms have BYTEORDER in config.h
213 based on sizeof(IV) rather than sizeof(long). This means that
214 the value of BYTEORDER will change from (say) 4321 to 87654321
215 between 5.6.1 and 5.8.0 built with the same options to Configure
216 on the same machine. This means that the Storable header will
217 differ, and the two versions will wrongly thing that they are
220 For the benefit of long term consistency, Storable now
221 implements the 5.8.0 BYTEORDER policy on 5.6.x. This means that
222 2.03 onwards default to be incompatible with 2.02 and earlier
223 (ie the large 1.0.x installed base) on the same 5.6.x perl.
225 To allow interworking, a new variable
226 $Storable::interwork_56_64bit is introduced. It defaults to
227 false. Set it to true to read and write old format files. Don't
228 use it unless you have existing stored data written with 5.6.x
229 that you couldn't otherwise read, or you need to interwork with
230 a machine running older Storable on a 5.6.x with long long IVs
231 (i.e., you probably don't need to use it).
233 Sat May 25 22:38:39 BST 2002 Nicholas Clark <nick@ccl4.org>
237 Rewrite Storable.xs so that the file header structure for write_magic
238 is built at compile time, and check_magic attempts to the header in
239 blocks rather than byte per byte. These changes make the compiled
240 extension 2.25% smaller, but are not significant enough to give a
243 Thu May 23 22:50:41 BST 2002 Nicholas Clark <nick@ccl4.org>
247 - New regression tests integer.t
248 - Add code to safely store large unsigned integers.
249 - Change code not to attempt to store large integers (ie > 32 bits)
250 in network order as 32 bits.
252 *Never* underestimate the value of a pathological test suite carefully
253 crafted with maximum malice before writing a line of real code. It
254 prevents crafty bugs from stowing away in your released code.
255 It's much less embarrassing to find them before you ship.
256 (Well, never underestimate it if you ever want to work for me)
258 Fri May 17 22:48:59 BST 2002 Nicholas Clark <nick@ccl4.org>
260 Version 2.0, binary format 2.5 (but writes format 2.4 on pre 5.7.3)
262 The perl5 porters have decided to make sure that Storable still
263 builds on pre-5.8 perls, and make the 5.8 version available on CPAN.
264 The VERSION is now 2.0, and it passes all tests on 5.005_03, 5.6.1
265 and 5.6.1 with threads. On 5.6.0 t/downgrade.t fails tests 34 and 37,
266 due to a bug in 5.6.0 - upgrade to 5.6.1.
268 Jarkko and I have collated the list of changes the perl5 porters have
269 from the perl5 Changes file:
271 - data features of upcoming perl 5.8.0 are supported: Unicode hash
272 keys (Unicode hash values have been supported since Storable 1.0.1)
273 and "restricted hashes" (readonly hashes and hash entries)
274 - a newer version of perl can now be used to serialize data which is
275 not supported in earlier perls: Storable will attempt to do the
276 right thing for as long as possible, croaking only when safe data
277 conversion simply isn't possible. Alternatively earlier perls can
278 opt to have a lossy downgrade data instead of croaking
279 - when built with perls pre 5.7.3 this Storable writes out files
280 with binary format 2.4, the same format as Storable 1.0.8 onwards.
281 This should mean that this Storable will inter-operate seamlessly
282 with any Storable 1.0.8 or newer on perls pre 5.7.3
283 - dclone() now works with empty string scalar objects
284 - retrieving of large hashes is now more efficient
285 - more routines autosplit out of the main module, so Storable should
286 load slightly more quickly
287 - better documentation
288 - the internal context objects are now freed explicitly, rather than
289 relying on thread or process exit
290 - bugs fixed in debugging trace code affecting builds made with 64 bit
292 - code tidy-ups to allow clean compiles with more warning options
293 turned on avoid problems with $@ getting corrupted on 5.005_03 if
294 Carp wasn't already loaded
295 - added &show_file_magic, so you can add to /etc/magic and teach
296 Unix's file command about Storable files
298 We plan to keep Storable on CPAN in sync with the Perl core, so
299 if you encounter bugs or other problems building or using Storable,
300 please let us know at perl5-porters@perl.org
303 Sat Dec 1 14:37:54 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
305 This is the LAST maintenance release of the Storable module.
306 Indeed, Storable is now part of perl 5.8, and will be maintained
307 as part of Perl. The CPAN module will remain available there
308 for people running pre-5.8 perls.
310 Avoid requiring Fcntl upfront, useful to embedded runtimes.
311 Use an eval {} for testing, instead of making Storable.pm
312 simply fail its compilation in the BEGIN block.
314 store_fd() will now correctly autoflush file if needed.
316 Tue Aug 28 23:53:20 MEST 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
318 Fixed truncation race with lock_retrieve() in lock_store().
319 The file has to be truncated only once the exclusive lock is held.
321 Removed spurious debugging messages in .xs file.
323 Sun Jul 1 13:27:32 MEST 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
325 Systematically use "=over 4" for POD linters.
326 Apparently, POD linters are much stricter than would
327 otherwise be needed, but that's OK.
329 Fixed memory corruption on croaks during thaw(). Thanks
330 to Claudio Garcia for reproducing this bug and providing the
331 code to exercise it. Added test cases for this bug, adapted
334 Made code compile cleanly with -Wall (from Jarkko Hietaniemi).
336 Changed tagnum and classnum from I32 to IV in context. Also
339 Thu Mar 15 01:22:32 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
341 Last version was wrongly compiling with assertions on, due
342 to an edit glitch. That did not cause any problem (apart from
343 a slight performance loss) excepted on Win* platforms, where the
344 assertion code does not compile.
346 Sat Feb 17 13:37:37 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
350 Forgot to increase version number at previous patch (there were
351 two of them, which is why we jump from 1.0.8 to 1.0.10).
353 Sat Feb 17 13:35:00 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
355 Version 1.0.8, binary format 2.4.
357 Fixed incorrect error message.
359 Now bless objects ASAP at retrieve time, which is meant to fix
362 * Indirect references to overloaded object were not able to
363 restore overloading if the object was not blessed yet,
364 which was possible since blessing occurred only after the
367 * Storable hooks asking for serialization of blessed ref could
368 get un-blessed refs at retrieval time, for the very same
371 The fix implemented here was suggested by Nick Ing-Simmons.
373 Added support for blessed ref to tied structures. This is the
374 cause for the binary format change.
376 Added EBCDIC version of the compatibility test with 0.6.11,
379 Added tests for the new features, and to make sure the bugs they
380 are meant to fix are indeed fixed.
382 Wed Jan 3 10:43:18 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
384 Removed spurious 'clean' entry in Makefile.PL.
386 Added CAN_FLOCK to determine whether we can flock() or not,
387 by inspecting Perl's configuration parameters, as determined
390 Trace offending package when overloading cannot be restored
393 Made context cleanup safer to avoid dup freeing, mostly in the
394 presence of repeated exceptions during store/retrieve (which can
395 cause memory leaks anyway, so it's just additional safety, not a
398 Sun Nov 5 18:23:48 MET 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
402 Fixed severe "object lost" bug for STORABLE_freeze returns,
403 when refs to lexicals, taken within the hook, were to be
404 serialized by Storable. Enhanced the t/recurse.t test to
405 stress hook a little more with refs to lexicals.
407 Thu Oct 26 19:14:38 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
411 Documented that store() and retrieve() can return undef.
412 That is, the error reporting is not always made via exceptions,
413 as the paragraph on error reporting was implying.
415 Auto requires module of blessed ref when STORABLE_thaw misses.
416 When the Storable engine looks for the STORABLE_thaw hook and
417 does not find it, it now tries to require the package into which
418 the blessed reference is.
420 Just check $^O, in t/lock.t: there's no need to pull the whole
421 Config module for that.
423 Mon Oct 23 20:03:49 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
427 Protected calls to flock() for DOS platform: apparently, the
428 flock/fcnlt emulation is reported to be broken on that
431 Added logcarp emulation if they don't have Log::Agent, since
432 we now use it to carp when lock_store/lock_retrieve is used
435 Fri Sep 29 21:52:29 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
439 Avoid using "tainted" and "dirty" since Perl remaps them via
440 cpp (i.e. #define). This is deeply harmful when threading
441 is enabled. This concerned both the context structure and
442 local variable and argument names. Brrr..., scary!
444 Thu Sep 28 23:46:39 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
448 Fixed spelling in README.
450 Added lock_store, lock_nstore, and lock_retrieve (advisory locking)
451 after a proposal from Erik Haugan <erik@solbors.no>.
453 Perls before 5.004_04 lack newSVpvn, added remapping in XS.
455 Fixed stupid typo in the t/utf8.t test.
457 Sun Sep 17 18:51:10 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
459 Version 1.0.1, binary format 2.3.
461 Documented that doubles are stored stringified by nstore().
463 Added Salvador Ortiz Garcia in CREDITS section, He identified
464 a bug in the store hooks and proposed the right fix: the class
465 id was allocated too soon. His bug case was also added to
466 the regression test suite.
468 Now only taint retrieved data when source was tainted. A bug
469 discovered by Marc Lehmann.
471 Added support for UTF-8 strings, a contribution of Marc Lehmann.
472 This is normally only activated in post-5.6 perls.
474 Thu Aug 31 23:06:06 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
476 First official release Storable 1.0, for inclusion in perl 5.7.0.
477 The license scheme is now compatible with Perl's.
479 Thu Aug 24 01:02:02 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
481 ANSI-fied most of the code, preparing for Perl core integration.
482 The next version of Storable will be 0.8, and will be integrated
483 into the Perl core (development branch).
485 Dispatch tables were moved upfront to relieve some compilers,
486 especially on AIX and Windows platforms.
488 Merged 64-bit fixes from perl5-porters.
490 Mon Aug 14 09:22:04 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
492 Added a refcnt dec in retrieve_tied_key(): sv_magic() increases
493 the refcnt on the mg_ptr as well.
495 Removed spurious dependency to Devel::Peek, which was used for
496 testing only in t/tied_items.t. Thanks to Conrad Heiney
497 <conrad@fringehead.org> for spotting it first.
499 Sun Aug 13 22:12:59 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
501 Marc Lehmann kindly contributed code to add overloading support
502 and to handle references to tied variables.
504 Rewrote leading blurb about compatibility to make it clearer what
505 "backward compatibility" is about: when I say 0.7 is backward
506 compatible with 0.6, it means the revision 0.7 can read files
509 Mention new Clone(3) extension in SEE ALSO.
511 Was wrongly optimizing for "undef" values in hashes by not
512 fully recursing: as a result, tied "undef" values were incorrectly
515 Sun Jul 30 12:59:17 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
517 First revision of Storable 0.7.
519 The serializing format is new, known as version 2.0. It is fully
520 backward compatible with 0.6. Earlier formats are deprecated and
521 have not even been tested: next version will drop pre-0.6 format.
523 Changes since 0.6@11:
525 - Moved interface to the "beta" status. Some tiny parts are still
526 subject to change, but nothing important enough to warrant an "alpha"
529 - Slightly reduced the size of the Storable image by factorizing
530 object class names and removing final object storage notification due
531 to a redesign of the blessed object storing.
533 - Classes can now redefine how they wish their instances to be serialized
534 and/or deep cloned. Serializing hooks are written in Perl code.
536 - The engine is now fully re-entrant.
538 Sun Apr 2 23:47:50 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
540 Added provision to detect more recent binary formats, since
541 the new upcoming Storable-0.7 will use a different format.
542 In order to prevent attempting the de-serialization of newer
543 formats by older versions, I'm adding this now to the 0.6 series.
545 I'm expecting this revision to be the last of the 0.6 series.
546 Unless it does not work with perl 5.6, which I don't use yet,
547 and therefore against which I cannot test.
549 Wed Mar 29 19:55:21 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
551 Added note about format incompatibilities with old versions
552 (i.e. pre 0.5@9 formats, which cannot be understood as there
553 was no versionning information in the file by then).
555 Protect all $@ variables when eval {} used, to avoid corrupting
556 it when store/retrieve is called within an exception handler.
558 Mistakenly included "patchlevel.h" instead of <patchlevel.h>,
559 preventing Perl's patchlevel from being included, which is
560 needed starting from 5.6.
562 Tue May 12 09:15:15 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
564 Fixed shared "undef" bug in hashes, which did not remain shared
565 through store/retrieve.
567 Thu Feb 10 19:48:16 MET 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
569 added last_op_in_netorder() predicate
570 documented last_op_in_netorder()
571 added tests for the new last_op_in_netorder() predicate
573 Wed Oct 20 19:07:36 MEST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
575 Forgot to update VERSION
577 Tue Oct 19 21:25:02 MEST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
579 Added mention of japanese translation for the manual page.
581 Fixed typo in macro that made threaded code not compilable,
582 especially on Win32 platforms.
584 Changed detection of older perls (pre-5.005) by testing PATCHLEVEL
585 directly instead of relying on internal symbols.
587 Tue Sep 14 22:13:28 MEST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
589 Integrated "thread-safe" patch from Murray Nesbitt.
590 Note that this may not be very efficient for threaded code,
591 see comment in the code.
593 Try to avoid compilation warning on 64-bit CPUs. Can't test it,
594 since I don't have access to such machines.
596 Mon Jul 12 14:37:19 METDST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
598 changed my e-mail to pobox.
600 mentioned it is not thread-safe.
602 updated version number.
604 uses new internal PL_* naming convention.
606 Fri Jul 3 13:38:16 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
608 Updated benchmark figures due to recent optimizations done in
609 store(): tagnums are now stored as-is in the hash table, so
610 no surrounding SV is created. And the "shared keys" mode for
611 hash table was turned off.
613 Fixed backward compatibility (wrt 0.5@9) for retrieval of
614 blessed refs. That old version did something wrong, but the
615 bugfix prevented correct retrieval of the old format.

619 Changed benchmark figures.
621 Adjust refcnt of tied objects after calling sv_magic() to avoid
622 memory leaks. Contributed by Jeff Gresham.

626 Added workaround for persistent LVALUE-ness in perl5.004. All
627 scalars tagged as being an lvalue are handled as if they were
628 not an lvalue at all. Added test for that LVALUE bug workaround.
630 Now handles Perl immortal scalars explicitly, by storing &sv_yes
633 Retrieval of non-immortal undef cannot be shared. Previous
634 version was over-optimizing by not creating a separate SV for
635 all undefined scalars seen.

639 Baseline for Storable-0.6@0.
641 This version introduces a binary incompatibility in the generated
642 binary image, which is more compact than older ones by approximatively
643 15%, depending on the exact degree of sharing in your structures.
645 The good news is that your older images can still be retrieved with
646 this version, i.e. backward compatibility is preserved. This version
647 of Storable can only generate new binaries however.
649 Another good news is that the retrieval of data structure is
650 significantly quicker than before, because a Perl array is used
651 instead of a hash table to keep track of retrieved objects, and
652 also because the image being smaller, less I/O function calls are

657 Version number now got from Storable.pm directly.
659 Fixed overzealous sv_type() optimization, which would make
660 Storable fail when faced with an "upgraded" SV to the PVIV
661 or PVNV kind containing a reference.

665 Extended the SYNOPSIS section to give quick overview of the
666 routines and their signature.
668 Optimized sv_type() to avoid flags checking when not needed, i.e.
669 when their type makes it impossible for them to be refs or tied.
670 This slightly increases throughput by a few percents when refs
671 and tied variables are marginal occurrences in your data.
673 Stubs for XS now use OutputStream and InputStream file types to
674 make it work when the given file is actually a socket. Perl
675 makes a distinction for sockets in its internal I/O structures
676 by having both a read and a write structure, whereas plain files

681 Thanks to a contribution from Benjamin A. Holzman, Storable is now
682 able to correctly serialize tied SVs, i.e. tied arrays, hashes

687 I said SvPOK() had changed to SvPOKp(), but that was a lie...
689 Wed Apr 8 13:14:29 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
691 Wrote sizeof(SV *) instead of sizeof(I32) when portable, which
692 in effect mangled the object tags and prevented portability
693 across 32/64 bit architectures!
695 Wed Mar 25 14:57:02 MET 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
697 Added code example for store_fd() and retrieve_fd() in the
698 man page, to emphasize that file descriptors must be passed as
699 globs, not as plain strings.
701 Cannot use SV addresses as tag when using nstore() on LP64. This
702 was the cause of problems when creating a storable image on an
703 LP64 machine and retrieving it on an ILP32 system, which is
704 exactly what nstore() is meant for...
706 However, we continue to use SV addresses as tags for plain store(),
707 because benchmarking shows that it saves up to 8% of the store
708 time, and store() is meant to be fast at the expense of lack
711 This means there will be approximately an 8% degradation of
712 performance for nstore(), but it's now working as expected.
713 That cost may vary on your machine of course, since it is
714 solely caused by the memory allocation overhead used to create
715 unique SV tags for each distinct stored SV.

719 Don't use any '_' in version number.
721 Tue Jan 13 17:51:50 MET 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
723 Updated version number.
725 added binmode() calls for systems where it matters.
727 Be sure to pass globs, not plain file strings, to C routines,
728 so that Storable can be used under the Perl debugger.
730 Wed Nov 5 10:53:22 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
732 Fix memory leaks on seen hash table and returned SV refs.
734 Storable did not work properly when tainting enabled.
736 Fixed "Allocation too large" messages in freeze/thaw and added.
737 proper regression test in t/freeze.t.
739 Tue Jun 3 09:41:33 METDST 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
741 Updated version number
743 Added freeze/thaw interface and dclone.
745 Fri May 16 10:45:47 METDST 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
747 Forgot that AutoLoader does not export its own AUTOLOAD.
750 use AutoLoader 'AUTOLOAD';
752 but that would not be backward compatible. So the export is

757 Empty scalar strings are now "defined" at retrieval time.
759 New test to ensure an empty string is defined when retrieved.
761 Thu Feb 27 16:32:44 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
763 Updated version number
765 Declare VERSION as being used
767 Fixed a typo in the PerlIO_putc remapping.
768 PerlIO_read and perlIO_write inverted size/nb_items.
769 (only relevant for pre-perl5.004 versions)
771 Thu Feb 27 15:58:31 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
773 Updated version number
775 Added VERSION identification
777 Allow build with perl5.003, which is ante perlIO time
779 Mon Jan 13 17:53:18 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
783 Wed Jan 22 15:19:56 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
785 Updated version number in Makefile.PL.
787 Added "thanks to" section to README.
789 Documented new forgive_me variable.
793 Added forgive_me support to allow store() of data structures
794 containing non-storable items like CODE refs.
