5 Includes hints/hpux.pl that was inadvertently left out of 2.20.
7 Mon May 18 09:38:20 IST 2009 Abhijit Menon-Sen <ams@toroid.org>
11 Fix bug handling blessed references to overloaded objects, plus
12 other miscellaneous fixes.
14 (Version 2.19 was released with 5.8.9.)
16 Thu Nov 22 13:24:18 IST 2007 Abhijit Menon-Sen <ams@toroid.org>
20 Compile fixes for older Perls. (No functional changes.)
22 Sat Nov 17 02:12:12 IST 2007 Abhijit Menon-Sen <ams@toroid.org>
26 Various broken tests fixed. (No functional changes.)
28 Sat Mar 31 06:11:06 IST 2007 Abhijit Menon-Sen <ams@toroid.org>
32 1. Fixes to Storable::dclone, read_magic, retrieve_lscalar
33 2. Storable 0.1 compatibility
34 3. Miscellaneous compile/leak/test/portability fixes
36 Mon May 23 22:48:49 IST 2005 Abhijit Menon-Sen <ams@wiw.org>
40 Minor changes to address a couple of compile problems.
42 Mon Apr 25 07:29:14 IST 2005 Abhijit Menon-Sen <ams@wiw.org>
46 1. Store weak references
47 2. Add STORABLE_attach hook.
49 Thu Jun 17 12:26:43 BST 2004 Nicholas Clark <nick@ccl4.org>
53 1. Don't change the type of top level overloaded references to RV -
54 they are perfectly correct as PVMG
55 2. Storable needs to cope with incoming frozen data that happens to be
58 Wed Mar 17 15:40:29 GMT 2004 Nicholas Clark <nick@ccl4.org>
62 1. Add regression tests for the auto-require of STORABLE_thaw
63 2. Add auto-require of modules to restore overloading (and tests)
64 3. Change to no context (should give speedup with ithreads)
66 Sat Mar 13 20:11:03 GMT 2004 Nicholas Clark <nick@ccl4.org>
70 1. Storing restricted hashes in canonical order would SEGV. Fixed.
71 2. It was impossible to retrieve references to PL_sv_no and and
72 PL_sv_undef from STORABLE_thaw hooks.
73 3. restrict.t was failing on 5.8.0, due to 5.8.0's unique
74 implementation of restricted hashes using PL_sv_undef
75 4. These changes allow a space optimisation for restricted hashes.
77 Sat Jan 24 16:22:32 IST 2004 Abhijit Menon-Sen <ams@wiw.org>
81 1. Thread safety: Storable::CLONE/init_perlinterp() now create
82 a new Perl context for each new ithread.
83 (From Stas Bekman and Jan Dubois.)
84 2. Fix a tag count mismatch with $Storable::Deparse that caused
85 all back-references after a stored sub to be off-by-N (where
86 N was the number of code references in between).
88 3. Prevent CODE references from turning into SCALAR references.
91 Sat Jan 3 18:49:18 GMT 2004 Nicholas Clark <nick@ccl4.org>
95 Fix minor problems with the CPAN release
96 1: Make Storable.xs work on 5.8.2 and later (already in the core)
97 2: Ship the linux hints file
98 3: Ship Test::More for the benefit of Perls pre 5.6.2
99 4: Correct Makefile.PL to only install in core for 5.8.0 and later
101 Sat Sep 6 01:08:20 IST 2003 Abhijit Menon-Sen <ams@wiw.org>
105 This release works around a 5.8.0 bug which caused hashes to not
106 be marked as having key flags even though an HEK had HEK_WASUTF8
107 set. (Note that the only reasonable solution is to silently drop
108 the flag from the affected key.)
110 Users of RT 3 who were seeing assertion failures should upgrade.
111 (Perl 5.8.1 will have the bug fixed.)
113 Mon May 5 10:24:16 IST 2003 Abhijit Menon-Sen <ams@wiw.org>
117 Minor bugfixes (self-tied objects are now correctly stored, as
118 are the results of additions larger than INT_MAX).
120 Mon Oct 7 21:56:38 BST 2002 Nicholas Clark <nick@ccl4.org>
124 Remove qr// from t/downgrade.t so that it will run on 5.004
125 Mention $File::Spec::VERSION a second time in t/forgive.t so that it
126 runs without warnings in 5.004 (this may be a 5.00405 bug I'm working
128 Fix t/integer.t initialisation to actually generate 64 bits of 9c
129 Fix comparison tests to use eval to get around 64 bit IV conversion
130 issues on 5.6.x, following my t/integer.t ^ precedence bug found by
132 Alter t/malice.t to work with Test/More.pm in t/, and skip individual
133 subtests that use $Config{ptrsize}, so that the rest of the test can
134 now be run with 5.004
135 Change t/malice.t and the error message in check_magic in Storable.xs
136 from "Pointer integer size" to "Pointer size"
137 Remove prerequisite of Test::More from Makefile.PL
138 Ship Test::Builder, Test::Simple and Test::More in t
140 Thu Oct 3 08:57:22 IST 2002 Abhijit Menon-Sen <ams@wiw.org>
144 Adds support for CODE references from Slaven Rezic
145 <slaven.rezic@berlin.de>.
147 Fri Jun 7 23:55:41 BST 2002 Nicholas Clark
151 Bug fix from Radu Greab <radu@netsoft.ro> (plus regression test)
152 to fix a recently introduced bug detected by Dave Rolsky.
153 Bug was that for a non threaded build, the class information was
154 being lost at freeze time on the first object with a STORABLE_freeze
155 hook. Consequentially the object was not blessed at all when thawed.
156 (The presence (or lack) of STORABLE_thaw was irrelevant; this was
157 a store-time data lost bug, caused by failure to initialize internal
159 The bug was introduced as development perl change 16442 (on
160 2002/05/07), so has been present since 2.00.
161 Patches to introduce more regression tests to reduce the chance of
162 a reoccurance of this sort of goof are always welcome.
164 Thu May 30 20:31:08 BST 2002 Nicholas Clark <nick@ccl4.org>
166 Version 2.03 Header changes on 5.6.x on Unix where IV is long long
168 5.6.x introduced the ability to have IVs as long long. However,
169 Configure still defined BYTEORDER based on the size of a long.
170 Storable uses the BYTEORDER value as part of the header, but
171 doesn't explicity store sizeof(IV) anywhere in the header.
172 Hence on 5.6.x built with IV as long long on a platform that
173 uses Configure (ie most things except VMS and Windows) headers
174 are identical for the different IV sizes, despite the files
175 containing some fields based on sizeof(IV)
177 5.8.0 is consistent; all platforms have BYTEORDER in config.h
178 based on sizeof(IV) rather than sizeof(long). This means that
179 the value of BYTEORDER will change from (say) 4321 to 87654321
180 between 5.6.1 and 5.8.0 built with the same options to Configure
181 on the same machine. This means that the Storable header will
182 differ, and the two versions will wrongly thing that they are
185 For the benefit of long term consistency, Storable now
186 implements the 5.8.0 BYTEORDER policy on 5.6.x. This means that
187 2.03 onwards default to be incompatible with 2.02 and earlier
188 (ie the large 1.0.x installed base) on the same 5.6.x perl.
190 To allow interworking, a new variable
191 $Storable::interwork_56_64bit is introduced. It defaults to
192 false. Set it to true to read and write old format files. Don't
193 use it unless you have existing stored data written with 5.6.x
194 that you couldn't otherwise read, or you need to interwork with
195 a machine running older Storable on a 5.6.x with long long IVs
196 (i.e., you probably don't need to use it).
198 Sat May 25 22:38:39 BST 2002 Nicholas Clark <nick@ccl4.org>
202 Rewrite Storable.xs so that the file header structure for write_magic
203 is built at compile time, and check_magic attempts to the header in
204 blocks rather than byte per byte. These changes make the compiled
205 extension 2.25% smaller, but are not significant enough to give a
208 Thu May 23 22:50:41 BST 2002 Nicholas Clark <nick@ccl4.org>
212 - New regression tests integer.t
213 - Add code to safely store large unsigned integers.
214 - Change code not to attempt to store large integers (ie > 32 bits)
215 in network order as 32 bits.
217 *Never* underestimate the value of a pathological test suite carefully
218 crafted with maximum malice before writing a line of real code. It
219 prevents crafty bugs from stowing away in your released code.
220 It's much less embarrassing to find them before you ship.
221 (Well, never underestimate it if you ever want to work for me)
223 Fri May 17 22:48:59 BST 2002 Nicholas Clark <nick@ccl4.org>
225 Version 2.0, binary format 2.5 (but writes format 2.4 on pre 5.7.3)
227 The perl5 porters have decided to make sure that Storable still
228 builds on pre-5.8 perls, and make the 5.8 version available on CPAN.
229 The VERSION is now 2.0, and it passes all tests on 5.005_03, 5.6.1
230 and 5.6.1 with threads. On 5.6.0 t/downgrade.t fails tests 34 and 37,
231 due to a bug in 5.6.0 - upgrade to 5.6.1.
233 Jarkko and I have collated the list of changes the perl5 porters have
234 from the perl5 Changes file:
236 - data features of upcoming perl 5.8.0 are supported: Unicode hash
237 keys (Unicode hash values have been supported since Storable 1.0.1)
238 and "restricted hashes" (readonly hashes and hash entries)
239 - a newer version of perl can now be used to serialize data which is
240 not supported in earlier perls: Storable will attempt to do the
241 right thing for as long as possible, croaking only when safe data
242 conversion simply isn't possible. Alternatively earlier perls can
243 opt to have a lossy downgrade data instead of croaking
244 - when built with perls pre 5.7.3 this Storable writes out files
245 with binary format 2.4, the same format as Storable 1.0.8 onwards.
246 This should mean that this Storable will inter-operate seamlessly
247 with any Storable 1.0.8 or newer on perls pre 5.7.3
248 - dclone() now works with empty string scalar objects
249 - retrieving of large hashes is now more efficient
250 - more routines autosplit out of the main module, so Storable should
251 load slightly more quickly
252 - better documentation
253 - the internal context objects are now freed explicitly, rather than
254 relying on thread or process exit
255 - bugs fixed in debugging trace code affecting builds made with 64 bit
257 - code tidy-ups to allow clean compiles with more warning options
258 turned on avoid problems with $@ getting corrupted on 5.005_03 if
259 Carp wasn't already loaded
260 - added &show_file_magic, so you can add to /etc/magic and teach
261 Unix's file command about Storable files
263 We plan to keep Storable on CPAN in sync with the Perl core, so
264 if you encounter bugs or other problems building or using Storable,
265 please let us know at perl5-porters@perl.org
268 Sat Dec 1 14:37:54 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
270 This is the LAST maintenance release of the Storable module.
271 Indeed, Storable is now part of perl 5.8, and will be maintained
272 as part of Perl. The CPAN module will remain available there
273 for people running pre-5.8 perls.
275 Avoid requiring Fcntl upfront, useful to embedded runtimes.
276 Use an eval {} for testing, instead of making Storable.pm
277 simply fail its compilation in the BEGIN block.
279 store_fd() will now correctly autoflush file if needed.
281 Tue Aug 28 23:53:20 MEST 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
283 Fixed truncation race with lock_retrieve() in lock_store().
284 The file has to be truncated only once the exclusive lock is held.
286 Removed spurious debugging messages in .xs file.
288 Sun Jul 1 13:27:32 MEST 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
290 Systematically use "=over 4" for POD linters.
291 Apparently, POD linters are much stricter than would
292 otherwise be needed, but that's OK.
294 Fixed memory corruption on croaks during thaw(). Thanks
295 to Claudio Garcia for reproducing this bug and providing the
296 code to exercise it. Added test cases for this bug, adapted
299 Made code compile cleanly with -Wall (from Jarkko Hietaniemi).
301 Changed tagnum and classnum from I32 to IV in context. Also
304 Thu Mar 15 01:22:32 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
306 Last version was wrongly compiling with assertions on, due
307 to an edit glitch. That did not cause any problem (apart from
308 a slight performance loss) excepted on Win* platforms, where the
309 assertion code does not compile.
311 Sat Feb 17 13:37:37 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
315 Forgot to increase version number at previous patch (there were
316 two of them, which is why we jump from 1.0.8 to 1.0.10).
318 Sat Feb 17 13:35:00 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
320 Version 1.0.8, binary format 2.4.
322 Fixed incorrect error message.
324 Now bless objects ASAP at retrieve time, which is meant to fix
327 * Indirect references to overloaded object were not able to
328 restore overloading if the object was not blessed yet,
329 which was possible since blessing occurred only after the
332 * Storable hooks asking for serialization of blessed ref could
333 get un-blessed refs at retrieval time, for the very same
336 The fix implemented here was suggested by Nick Ing-Simmons.
338 Added support for blessed ref to tied structures. This is the
339 cause for the binary format change.
341 Added EBCDIC version of the compatibility test with 0.6.11,
344 Added tests for the new features, and to make sure the bugs they
345 are meant to fix are indeed fixed.
347 Wed Jan 3 10:43:18 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
349 Removed spurious 'clean' entry in Makefile.PL.
351 Added CAN_FLOCK to determine whether we can flock() or not,
352 by inspecting Perl's configuration parameters, as determined
355 Trace offending package when overloading cannot be restored
358 Made context cleanup safer to avoid dup freeing, mostly in the
359 presence of repeated exceptions during store/retrieve (which can
360 cause memory leaks anyway, so it's just additional safety, not a
363 Sun Nov 5 18:23:48 MET 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
367 Fixed severe "object lost" bug for STORABLE_freeze returns,
368 when refs to lexicals, taken within the hook, were to be
369 serialized by Storable. Enhanced the t/recurse.t test to
370 stress hook a little more with refs to lexicals.
372 Thu Oct 26 19:14:38 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
376 Documented that store() and retrieve() can return undef.
377 That is, the error reporting is not always made via exceptions,
378 as the paragraph on error reporting was implying.
380 Auto requires module of blessed ref when STORABLE_thaw misses.
381 When the Storable engine looks for the STORABLE_thaw hook and
382 does not find it, it now tries to require the package into which
383 the blessed reference is.
385 Just check $^O, in t/lock.t: there's no need to pull the whole
386 Config module for that.
388 Mon Oct 23 20:03:49 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
392 Protected calls to flock() for DOS platform: apparently, the
393 flock/fcnlt emulation is reported to be broken on that
396 Added logcarp emulation if they don't have Log::Agent, since
397 we now use it to carp when lock_store/lock_retrieve is used
400 Fri Sep 29 21:52:29 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
404 Avoid using "tainted" and "dirty" since Perl remaps them via
405 cpp (i.e. #define). This is deeply harmful when threading
406 is enabled. This concerned both the context structure and
407 local variable and argument names. Brrr..., scary!
409 Thu Sep 28 23:46:39 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
413 Fixed spelling in README.
415 Added lock_store, lock_nstore, and lock_retrieve (advisory locking)
416 after a proposal from Erik Haugan <erik@solbors.no>.
418 Perls before 5.004_04 lack newSVpvn, added remapping in XS.
420 Fixed stupid typo in the t/utf8.t test.
422 Sun Sep 17 18:51:10 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
424 Version 1.0.1, binary format 2.3.
426 Documented that doubles are stored stringified by nstore().
428 Added Salvador Ortiz Garcia in CREDITS section, He identified
429 a bug in the store hooks and proposed the right fix: the class
430 id was allocated too soon. His bug case was also added to
431 the regression test suite.
433 Now only taint retrieved data when source was tainted. A bug
434 discovered by Marc Lehmann.
436 Added support for UTF-8 strings, a contribution of Marc Lehmann.
437 This is normally only activated in post-5.6 perls.
439 Thu Aug 31 23:06:06 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
441 First official release Storable 1.0, for inclusion in perl 5.7.0.
442 The license scheme is now compatible with Perl's.
444 Thu Aug 24 01:02:02 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
446 ANSI-fied most of the code, preparing for Perl core integration.
447 The next version of Storable will be 0.8, and will be integrated
448 into the Perl core (development branch).
450 Dispatch tables were moved upfront to relieve some compilers,
451 especially on AIX and Windows platforms.
453 Merged 64-bit fixes from perl5-porters.
455 Mon Aug 14 09:22:04 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
457 Added a refcnt dec in retrieve_tied_key(): sv_magic() increases
458 the refcnt on the mg_ptr as well.
460 Removed spurious dependency to Devel::Peek, which was used for
461 testing only in t/tied_items.t. Thanks to Conrad Heiney
462 <conrad@fringehead.org> for spotting it first.
464 Sun Aug 13 22:12:59 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
466 Marc Lehmann kindly contributed code to add overloading support
467 and to handle references to tied variables.
469 Rewrote leading blurb about compatibility to make it clearer what
470 "backward compatibility" is about: when I say 0.7 is backward
471 compatible with 0.6, it means the revision 0.7 can read files
474 Mention new Clone(3) extension in SEE ALSO.
476 Was wrongly optimizing for "undef" values in hashes by not
477 fully recursing: as a result, tied "undef" values were incorrectly
480 Sun Jul 30 12:59:17 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
482 First revision of Storable 0.7.
484 The serializing format is new, known as version 2.0. It is fully
485 backward compatible with 0.6. Earlier formats are deprecated and
486 have not even been tested: next version will drop pre-0.6 format.
488 Changes since 0.6@11:
490 - Moved interface to the "beta" status. Some tiny parts are still
491 subject to change, but nothing important enough to warrant an "alpha"
494 - Slightly reduced the size of the Storable image by factorizing
495 object class names and removing final object storage notification due
496 to a redesign of the blessed object storing.
498 - Classes can now redefine how they wish their instances to be serialized
499 and/or deep cloned. Serializing hooks are written in Perl code.
501 - The engine is now fully re-entrant.
503 Sun Apr 2 23:47:50 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
505 Added provision to detect more recent binary formats, since
506 the new upcoming Storable-0.7 will use a different format.
507 In order to prevent attempting the de-serialization of newer
508 formats by older versions, I'm adding this now to the 0.6 series.
510 I'm expecting this revision to be the last of the 0.6 series.
511 Unless it does not work with perl 5.6, which I don't use yet,
512 and therefore against which I cannot test.
514 Wed Mar 29 19:55:21 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
516 Added note about format incompatibilities with old versions
517 (i.e. pre 0.5@9 formats, which cannot be understood as there
518 was no versionning information in the file by then).
520 Protect all $@ variables when eval {} used, to avoid corrupting
521 it when store/retrieve is called within an exception handler.
523 Mistakenly included "patchlevel.h" instead of <patchlevel.h>,
524 preventing Perl's patchlevel from being included, which is
525 needed starting from 5.6.
527 Tue May 12 09:15:15 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
529 Fixed shared "undef" bug in hashes, which did not remain shared
530 through store/retrieve.
532 Thu Feb 10 19:48:16 MET 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
534 added last_op_in_netorder() predicate
535 documented last_op_in_netorder()
536 added tests for the new last_op_in_netorder() predicate
538 Wed Oct 20 19:07:36 MEST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
540 Forgot to update VERSION
542 Tue Oct 19 21:25:02 MEST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
544 Added mention of japanese translation for the manual page.
546 Fixed typo in macro that made threaded code not compilable,
547 especially on Win32 platforms.
549 Changed detection of older perls (pre-5.005) by testing PATCHLEVEL
550 directly instead of relying on internal symbols.
552 Tue Sep 14 22:13:28 MEST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
554 Integrated "thread-safe" patch from Murray Nesbitt.
555 Note that this may not be very efficient for threaded code,
556 see comment in the code.
558 Try to avoid compilation warning on 64-bit CPUs. Can't test it,
559 since I don't have access to such machines.
561 Mon Jul 12 14:37:19 METDST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
563 changed my e-mail to pobox.
565 mentionned it is not thread-safe.
567 updated version number.
569 uses new internal PL_* naming convention.
571 Fri Jul 3 13:38:16 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
573 Updated benchmark figures due to recent optimizations done in
574 store(): tagnums are now stored as-is in the hash table, so
575 no surrounding SV is created. And the "shared keys" mode for
576 hash table was turned off.
578 Fixed backward compatibility (wrt 0.5@9) for retrieval of
579 blessed refs. That old version did something wrong, but the
580 bugfix prevented correct retrieval of the old format.
582 Mon Jun 22 11:00:48 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
584 Changed benchmark figures.
586 Adjust refcnt of tied objects after calling sv_magic() to avoid
587 memory leaks. Contributed by Jeff Gresham.
589 Fri Jun 12 11:50:04 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
591 Added workaround for persistent LVALUE-ness in perl5.004. All
592 scalars tagged as being an lvalue are handled as if they were
593 not an lvalue at all. Added test for that LVALUE bug workaround.
595 Now handles Perl immortal scalars explicitely, by storing &sv_yes
596 as such, explicitely.
598 Retrieval of non-immortal undef cannot be shared. Previous
599 version was over-optimizing by not creating a separate SV for
600 all undefined scalars seen.
602 Thu Jun 4 17:21:51 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
604 Baseline for Storable-0.6@0.
606 This version introduces a binary incompatibility in the generated
607 binary image, which is more compact than older ones by approximatively
608 15%, depending on the exact degree of sharing in your structures.
610 The good news is that your older images can still be retrieved with
611 this version, i.e. backward compatibility is preserved. This version
612 of Storable can only generate new binaries however.
614 Another good news is that the retrieval of data structure is
615 significantly quicker than before, because a Perl array is used
616 instead of a hash table to keep track of retrieved objects, and
617 also because the image being smaller, less I/O function calls are

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

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

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

652 I said SvPOK() had changed to SvPOKp(), but that was a lie...
654 Wed Apr 8 13:14:29 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
656 Wrote sizeof(SV *) instead of sizeof(I32) when portable, which
657 in effect mangled the object tags and prevented portability
658 accross 32/64 bit architectures!
660 Wed Mar 25 14:57:02 MET 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
662 Added code example for store_fd() and retrieve_fd() in the
663 man page, to emphasize that file descriptors must be passed as
664 globs, not as plain strings.
666 Cannot use SV addresses as tag when using nstore() on LP64. This
667 was the cause of problems when creating a storable image on an
668 LP64 machine and retrieving it on an ILP32 system, which is
669 exactly what nstore() is meant for...
671 However, we continue to use SV addresses as tags for plain store(),
672 because benchamarking shows that it saves up to 8% of the store
673 time, and store() is meant to be fast at the expense of lack
676 This means there will be approximately an 8% degradation of
677 performance for nstore(), but it's now working as expected.
678 That cost may vary on your machine of course, since it is
679 solely caused by the memory allocation overhead used to create
680 unique SV tags for each distinct stored SV.

684 Don't use any '_' in version number.
686 Tue Jan 13 17:51:50 MET 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
688 Updated version number.
690 added binmode() calls for systems where it matters.
692 Be sure to pass globs, not plain file strings, to C routines,
693 so that Storable can be used under the Perl debugger.
695 Wed Nov 5 10:53:22 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
697 Fix memory leaks on seen hash table and returned SV refs.
699 Storable did not work properly when tainting enabled.
701 Fixed "Allocation too large" messages in freeze/thaw and added.
702 proper regression test in t/freeze.t.
704 Tue Jun 3 09:41:33 METDST 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
706 Updated version number
708 Added freeze/thaw interface and dclone.

712 Forgot that AutoLoader does not export its own AUTOLOAD.
715 use AutoLoader 'AUTOLOAD';
717 but that would not be backward compatible. So the export is

722 Empty scalar strings are now "defined" at retrieval time.
724 New test to ensure an empty string is defined when retrieved.

728 Updated version number
730 Declare VERSION as being used
732 Fixed a typo in the PerlIO_putc remapping.
733 PerlIO_read and perlIO_write inverted size/nb_items.
734 (only relevant for pre-perl5.004 versions)
736 Thu Feb 27 15:58:31 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
738 Updated version number
740 Added VERSION identification
