5 Compile fixes for older Perls. (No functional changes.)
7 Sat Nov 17 02:12:12 IST 2007 Abhijit Menon-Sen <ams@toroid.org>
11 Various broken tests fixed. (No functional changes.)
13 Sat Mar 31 06:11:06 IST 2007 Abhijit Menon-Sen <ams@toroid.org>
17 1. Fixes to Storable::dclone, read_magic, retrieve_lscalar
18 2. Storable 0.1 compatibility
19 3. Miscellaneous compile/leak/test/portability fixes
21 Mon May 23 22:48:49 IST 2005 Abhijit Menon-Sen <ams@wiw.org>
25 Minor changes to address a couple of compile problems.
27 Mon Apr 25 07:29:14 IST 2005 Abhijit Menon-Sen <ams@wiw.org>
31 1. Store weak references
32 2. Add STORABLE_attach hook.
34 Thu Jun 17 12:26:43 BST 2004 Nicholas Clark <nick@ccl4.org>
38 1. Don't change the type of top level overloaded references to RV -
39 they are perfectly correct as PVMG
40 2. Storable needs to cope with incoming frozen data that happens to be
43 Wed Mar 17 15:40:29 GMT 2004 Nicholas Clark <nick@ccl4.org>
47 1. Add regression tests for the auto-require of STORABLE_thaw
48 2. Add auto-require of modules to restore overloading (and tests)
49 3. Change to no context (should give speedup with ithreads)
51 Sat Mar 13 20:11:03 GMT 2004 Nicholas Clark <nick@ccl4.org>
55 1. Storing restricted hashes in canonical order would SEGV. Fixed.
56 2. It was impossible to retrieve references to PL_sv_no and and
57 PL_sv_undef from STORABLE_thaw hooks.
58 3. restrict.t was failing on 5.8.0, due to 5.8.0's unique
59 implementation of restricted hashes using PL_sv_undef
60 4. These changes allow a space optimisation for restricted hashes.
62 Sat Jan 24 16:22:32 IST 2004 Abhijit Menon-Sen <ams@wiw.org>
66 1. Thread safety: Storable::CLONE/init_perlinterp() now create
67 a new Perl context for each new ithread.
68 (From Stas Bekman and Jan Dubois.)
69 2. Fix a tag count mismatch with $Storable::Deparse that caused
70 all back-references after a stored sub to be off-by-N (where
71 N was the number of code references in between).
73 3. Prevent CODE references from turning into SCALAR references.
76 Sat Jan 3 18:49:18 GMT 2004 Nicholas Clark <nick@ccl4.org>
80 Fix minor problems with the CPAN release
81 1: Make Storable.xs work on 5.8.2 and later (already in the core)
82 2: Ship the linux hints file
83 3: Ship Test::More for the benefit of Perls pre 5.6.2
84 4: Correct Makefile.PL to only install in core for 5.8.0 and later
86 Sat Sep 6 01:08:20 IST 2003 Abhijit Menon-Sen <ams@wiw.org>
90 This release works around a 5.8.0 bug which caused hashes to not
91 be marked as having key flags even though an HEK had HEK_WASUTF8
92 set. (Note that the only reasonable solution is to silently drop
93 the flag from the affected key.)
95 Users of RT 3 who were seeing assertion failures should upgrade.
96 (Perl 5.8.1 will have the bug fixed.)
98 Mon May 5 10:24:16 IST 2003 Abhijit Menon-Sen <ams@wiw.org>
102 Minor bugfixes (self-tied objects are now correctly stored, as
103 are the results of additions larger than INT_MAX).
105 Mon Oct 7 21:56:38 BST 2002 Nicholas Clark <nick@ccl4.org>
109 Remove qr// from t/downgrade.t so that it will run on 5.004
110 Mention $File::Spec::VERSION a second time in t/forgive.t so that it
111 runs without warnings in 5.004 (this may be a 5.00405 bug I'm working
113 Fix t/integer.t initialisation to actually generate 64 bits of 9c
114 Fix comparison tests to use eval to get around 64 bit IV conversion
115 issues on 5.6.x, following my t/integer.t ^ precedence bug found by
117 Alter t/malice.t to work with Test/More.pm in t/, and skip individual
118 subtests that use $Config{ptrsize}, so that the rest of the test can
119 now be run with 5.004
120 Change t/malice.t and the error message in check_magic in Storable.xs
121 from "Pointer integer size" to "Pointer size"
122 Remove prerequisite of Test::More from Makefile.PL
123 Ship Test::Builder, Test::Simple and Test::More in t
125 Thu Oct 3 08:57:22 IST 2002 Abhijit Menon-Sen <ams@wiw.org>
129 Adds support for CODE references from Slaven Rezic
130 <slaven.rezic@berlin.de>.
132 Fri Jun 7 23:55:41 BST 2002 Nicholas Clark
136 Bug fix from Radu Greab <radu@netsoft.ro> (plus regression test)
137 to fix a recently introduced bug detected by Dave Rolsky.
138 Bug was that for a non threaded build, the class information was
139 being lost at freeze time on the first object with a STORABLE_freeze
140 hook. Consequentially the object was not blessed at all when thawed.
141 (The presence (or lack) of STORABLE_thaw was irrelevant; this was
142 a store-time data lost bug, caused by failure to initialize internal
144 The bug was introduced as development perl change 16442 (on
145 2002/05/07), so has been present since 2.00.
146 Patches to introduce more regression tests to reduce the chance of
147 a reoccurance of this sort of goof are always welcome.
149 Thu May 30 20:31:08 BST 2002 Nicholas Clark <nick@ccl4.org>
151 Version 2.03 Header changes on 5.6.x on Unix where IV is long long
153 5.6.x introduced the ability to have IVs as long long. However,
154 Configure still defined BYTEORDER based on the size of a long.
155 Storable uses the BYTEORDER value as part of the header, but
156 doesn't explicity store sizeof(IV) anywhere in the header.
157 Hence on 5.6.x built with IV as long long on a platform that
158 uses Configure (ie most things except VMS and Windows) headers
159 are identical for the different IV sizes, despite the files
160 containing some fields based on sizeof(IV)
162 5.8.0 is consistent; all platforms have BYTEORDER in config.h
163 based on sizeof(IV) rather than sizeof(long). This means that
164 the value of BYTEORDER will change from (say) 4321 to 87654321
165 between 5.6.1 and 5.8.0 built with the same options to Configure
166 on the same machine. This means that the Storable header will
167 differ, and the two versions will wrongly thing that they are
170 For the benefit of long term consistency, Storable now
171 implements the 5.8.0 BYTEORDER policy on 5.6.x. This means that
172 2.03 onwards default to be incompatible with 2.02 and earlier
173 (ie the large 1.0.x installed base) on the same 5.6.x perl.
175 To allow interworking, a new variable
176 $Storable::interwork_56_64bit is introduced. It defaults to
177 false. Set it to true to read and write old format files. Don't
178 use it unless you have existing stored data written with 5.6.x
179 that you couldn't otherwise read, or you need to interwork with
180 a machine running older Storable on a 5.6.x with long long IVs
181 (i.e., you probably don't need to use it).
183 Sat May 25 22:38:39 BST 2002 Nicholas Clark <nick@ccl4.org>
187 Rewrite Storable.xs so that the file header structure for write_magic
188 is built at compile time, and check_magic attempts to the header in
189 blocks rather than byte per byte. These changes make the compiled
190 extension 2.25% smaller, but are not significant enough to give a
193 Thu May 23 22:50:41 BST 2002 Nicholas Clark <nick@ccl4.org>
197 - New regression tests integer.t
198 - Add code to safely store large unsigned integers.
199 - Change code not to attempt to store large integers (ie > 32 bits)
200 in network order as 32 bits.
202 *Never* underestimate the value of a pathological test suite carefully
203 crafted with maximum malice before writing a line of real code. It
204 prevents crafty bugs from stowing away in your released code.
205 It's much less embarrassing to find them before you ship.
206 (Well, never underestimate it if you ever want to work for me)
208 Fri May 17 22:48:59 BST 2002 Nicholas Clark <nick@ccl4.org>
210 Version 2.0, binary format 2.5 (but writes format 2.4 on pre 5.7.3)
212 The perl5 porters have decided to make sure that Storable still
213 builds on pre-5.8 perls, and make the 5.8 version available on CPAN.
214 The VERSION is now 2.0, and it passes all tests on 5.005_03, 5.6.1
215 and 5.6.1 with threads. On 5.6.0 t/downgrade.t fails tests 34 and 37,
216 due to a bug in 5.6.0 - upgrade to 5.6.1.
218 Jarkko and I have collated the list of changes the perl5 porters have
219 from the perl5 Changes file:
221 - data features of upcoming perl 5.8.0 are supported: Unicode hash
222 keys (Unicode hash values have been supported since Storable 1.0.1)
223 and "restricted hashes" (readonly hashes and hash entries)
224 - a newer version of perl can now be used to serialize data which is
225 not supported in earlier perls: Storable will attempt to do the
226 right thing for as long as possible, croaking only when safe data
227 conversion simply isn't possible. Alternatively earlier perls can
228 opt to have a lossy downgrade data instead of croaking
229 - when built with perls pre 5.7.3 this Storable writes out files
230 with binary format 2.4, the same format as Storable 1.0.8 onwards.
231 This should mean that this Storable will inter-operate seamlessly
232 with any Storable 1.0.8 or newer on perls pre 5.7.3
233 - dclone() now works with empty string scalar objects
234 - retrieving of large hashes is now more efficient
235 - more routines autosplit out of the main module, so Storable should
236 load slightly more quickly
237 - better documentation
238 - the internal context objects are now freed explicitly, rather than
239 relying on thread or process exit
240 - bugs fixed in debugging trace code affecting builds made with 64 bit
242 - code tidy-ups to allow clean compiles with more warning options
243 turned on avoid problems with $@ getting corrupted on 5.005_03 if
244 Carp wasn't already loaded
245 - added &show_file_magic, so you can add to /etc/magic and teach
246 Unix's file command about Storable files
248 We plan to keep Storable on CPAN in sync with the Perl core, so
249 if you encounter bugs or other problems building or using Storable,
250 please let us know at perl5-porters@perl.org
253 Sat Dec 1 14:37:54 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
255 This is the LAST maintenance release of the Storable module.
256 Indeed, Storable is now part of perl 5.8, and will be maintained
257 as part of Perl. The CPAN module will remain available there
258 for people running pre-5.8 perls.
260 Avoid requiring Fcntl upfront, useful to embedded runtimes.
261 Use an eval {} for testing, instead of making Storable.pm
262 simply fail its compilation in the BEGIN block.
264 store_fd() will now correctly autoflush file if needed.
266 Tue Aug 28 23:53:20 MEST 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
268 Fixed truncation race with lock_retrieve() in lock_store().
269 The file has to be truncated only once the exclusive lock is held.
271 Removed spurious debugging messages in .xs file.
273 Sun Jul 1 13:27:32 MEST 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
275 Systematically use "=over 4" for POD linters.
276 Apparently, POD linters are much stricter than would
277 otherwise be needed, but that's OK.
279 Fixed memory corruption on croaks during thaw(). Thanks
280 to Claudio Garcia for reproducing this bug and providing the
281 code to exercise it. Added test cases for this bug, adapted
284 Made code compile cleanly with -Wall (from Jarkko Hietaniemi).
286 Changed tagnum and classnum from I32 to IV in context. Also
289 Thu Mar 15 01:22:32 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
291 Last version was wrongly compiling with assertions on, due
292 to an edit glitch. That did not cause any problem (apart from
293 a slight performance loss) excepted on Win* platforms, where the
294 assertion code does not compile.
296 Sat Feb 17 13:37:37 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
300 Forgot to increase version number at previous patch (there were
301 two of them, which is why we jump from 1.0.8 to 1.0.10).
303 Sat Feb 17 13:35:00 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
305 Version 1.0.8, binary format 2.4.
307 Fixed incorrect error message.
309 Now bless objects ASAP at retrieve time, which is meant to fix
312 * Indirect references to overloaded object were not able to
313 restore overloading if the object was not blessed yet,
314 which was possible since blessing occurred only after the
317 * Storable hooks asking for serialization of blessed ref could
318 get un-blessed refs at retrieval time, for the very same
321 The fix implemented here was suggested by Nick Ing-Simmons.
323 Added support for blessed ref to tied structures. This is the
324 cause for the binary format change.
326 Added EBCDIC version of the compatibility test with 0.6.11,
329 Added tests for the new features, and to make sure the bugs they
330 are meant to fix are indeed fixed.
332 Wed Jan 3 10:43:18 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
334 Removed spurious 'clean' entry in Makefile.PL.
336 Added CAN_FLOCK to determine whether we can flock() or not,
337 by inspecting Perl's configuration parameters, as determined
340 Trace offending package when overloading cannot be restored
343 Made context cleanup safer to avoid dup freeing, mostly in the
344 presence of repeated exceptions during store/retrieve (which can
345 cause memory leaks anyway, so it's just additional safety, not a
348 Sun Nov 5 18:23:48 MET 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
352 Fixed severe "object lost" bug for STORABLE_freeze returns,
353 when refs to lexicals, taken within the hook, were to be
354 serialized by Storable. Enhanced the t/recurse.t test to
355 stress hook a little more with refs to lexicals.
357 Thu Oct 26 19:14:38 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
361 Documented that store() and retrieve() can return undef.
362 That is, the error reporting is not always made via exceptions,
363 as the paragraph on error reporting was implying.
365 Auto requires module of blessed ref when STORABLE_thaw misses.
366 When the Storable engine looks for the STORABLE_thaw hook and
367 does not find it, it now tries to require the package into which
368 the blessed reference is.
370 Just check $^O, in t/lock.t: there's no need to pull the whole
371 Config module for that.
373 Mon Oct 23 20:03:49 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
377 Protected calls to flock() for DOS platform: apparently, the
378 flock/fcnlt emulation is reported to be broken on that
381 Added logcarp emulation if they don't have Log::Agent, since
382 we now use it to carp when lock_store/lock_retrieve is used
385 Fri Sep 29 21:52:29 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
389 Avoid using "tainted" and "dirty" since Perl remaps them via
390 cpp (i.e. #define). This is deeply harmful when threading
391 is enabled. This concerned both the context structure and
392 local variable and argument names. Brrr..., scary!
394 Thu Sep 28 23:46:39 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
398 Fixed spelling in README.
400 Added lock_store, lock_nstore, and lock_retrieve (advisory locking)
401 after a proposal from Erik Haugan <erik@solbors.no>.
403 Perls before 5.004_04 lack newSVpvn, added remapping in XS.
405 Fixed stupid typo in the t/utf8.t test.
407 Sun Sep 17 18:51:10 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
409 Version 1.0.1, binary format 2.3.
411 Documented that doubles are stored stringified by nstore().
413 Added Salvador Ortiz Garcia in CREDITS section, He identified
414 a bug in the store hooks and proposed the right fix: the class
415 id was allocated too soon. His bug case was also added to
416 the regression test suite.
418 Now only taint retrieved data when source was tainted. A bug
419 discovered by Marc Lehmann.
421 Added support for UTF-8 strings, a contribution of Marc Lehmann.
422 This is normally only activated in post-5.6 perls.
424 Thu Aug 31 23:06:06 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
426 First official release Storable 1.0, for inclusion in perl 5.7.0.
427 The license scheme is now compatible with Perl's.
429 Thu Aug 24 01:02:02 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
431 ANSI-fied most of the code, preparing for Perl core integration.
432 The next version of Storable will be 0.8, and will be integrated
433 into the Perl core (development branch).
435 Dispatch tables were moved upfront to relieve some compilers,
436 especially on AIX and Windows platforms.
438 Merged 64-bit fixes from perl5-porters.
440 Mon Aug 14 09:22:04 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
442 Added a refcnt dec in retrieve_tied_key(): sv_magic() increases
443 the refcnt on the mg_ptr as well.
445 Removed spurious dependency to Devel::Peek, which was used for
446 testing only in t/tied_items.t. Thanks to Conrad Heiney
447 <conrad@fringehead.org> for spotting it first.
449 Sun Aug 13 22:12:59 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
451 Marc Lehmann kindly contributed code to add overloading support
452 and to handle references to tied variables.
454 Rewrote leading blurb about compatibility to make it clearer what
455 "backward compatibility" is about: when I say 0.7 is backward
456 compatible with 0.6, it means the revision 0.7 can read files
459 Mention new Clone(3) extension in SEE ALSO.
461 Was wrongly optimizing for "undef" values in hashes by not
462 fully recursing: as a result, tied "undef" values were incorrectly
465 Sun Jul 30 12:59:17 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
467 First revision of Storable 0.7.
469 The serializing format is new, known as version 2.0. It is fully
470 backward compatible with 0.6. Earlier formats are deprecated and
471 have not even been tested: next version will drop pre-0.6 format.
473 Changes since 0.6@11:
475 - Moved interface to the "beta" status. Some tiny parts are still
476 subject to change, but nothing important enough to warrant an "alpha"
479 - Slightly reduced the size of the Storable image by factorizing
480 object class names and removing final object storage notification due
481 to a redesign of the blessed object storing.
483 - Classes can now redefine how they wish their instances to be serialized
484 and/or deep cloned. Serializing hooks are written in Perl code.
486 - The engine is now fully re-entrant.
488 Sun Apr 2 23:47:50 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
490 Added provision to detect more recent binary formats, since
491 the new upcoming Storable-0.7 will use a different format.
492 In order to prevent attempting the de-serialization of newer
493 formats by older versions, I'm adding this now to the 0.6 series.
495 I'm expecting this revision to be the last of the 0.6 series.
496 Unless it does not work with perl 5.6, which I don't use yet,
497 and therefore against which I cannot test.
499 Wed Mar 29 19:55:21 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
501 Added note about format incompatibilities with old versions
502 (i.e. pre 0.5@9 formats, which cannot be understood as there
503 was no versionning information in the file by then).
505 Protect all $@ variables when eval {} used, to avoid corrupting
506 it when store/retrieve is called within an exception handler.
508 Mistakenly included "patchlevel.h" instead of <patchlevel.h>,
509 preventing Perl's patchlevel from being included, which is
510 needed starting from 5.6.
512 Tue May 12 09:15:15 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
514 Fixed shared "undef" bug in hashes, which did not remain shared
515 through store/retrieve.
517 Thu Feb 10 19:48:16 MET 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
519 added last_op_in_netorder() predicate
520 documented last_op_in_netorder()
521 added tests for the new last_op_in_netorder() predicate
523 Wed Oct 20 19:07:36 MEST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
525 Forgot to update VERSION
527 Tue Oct 19 21:25:02 MEST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
529 Added mention of japanese translation for the manual page.
531 Fixed typo in macro that made threaded code not compilable,
532 especially on Win32 platforms.
534 Changed detection of older perls (pre-5.005) by testing PATCHLEVEL
535 directly instead of relying on internal symbols.
537 Tue Sep 14 22:13:28 MEST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
539 Integrated "thread-safe" patch from Murray Nesbitt.
540 Note that this may not be very efficient for threaded code,
541 see comment in the code.
543 Try to avoid compilation warning on 64-bit CPUs. Can't test it,
544 since I don't have access to such machines.
546 Mon Jul 12 14:37:19 METDST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
548 changed my e-mail to pobox.
550 mentionned it is not thread-safe.
552 updated version number.
554 uses new internal PL_* naming convention.
556 Fri Jul 3 13:38:16 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
558 Updated benchmark figures due to recent optimizations done in
559 store(): tagnums are now stored as-is in the hash table, so
560 no surrounding SV is created. And the "shared keys" mode for
561 hash table was turned off.
563 Fixed backward compatibility (wrt 0.5@9) for retrieval of
564 blessed refs. That old version did something wrong, but the
565 bugfix prevented correct retrieval of the old format.
567 Mon Jun 22 11:00:48 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
569 Changed benchmark figures.
571 Adjust refcnt of tied objects after calling sv_magic() to avoid
572 memory leaks. Contributed by Jeff Gresham.
574 Fri Jun 12 11:50:04 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
576 Added workaround for persistent LVALUE-ness in perl5.004. All
577 scalars tagged as being an lvalue are handled as if they were
578 not an lvalue at all. Added test for that LVALUE bug workaround.
580 Now handles Perl immortal scalars explicitely, by storing &sv_yes
581 as such, explicitely.
583 Retrieval of non-immortal undef cannot be shared. Previous
584 version was over-optimizing by not creating a separate SV for
585 all undefined scalars seen.
587 Thu Jun 4 17:21:51 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
589 Baseline for Storable-0.6@0.
591 This version introduces a binary incompatibility in the generated
592 binary image, which is more compact than older ones by approximatively
593 15%, depending on the exact degree of sharing in your structures.
595 The good news is that your older images can still be retrieved with
596 this version, i.e. backward compatibility is preserved. This version
597 of Storable can only generate new binaries however.
599 Another good news is that the retrieval of data structure is
600 significantly quicker than before, because a Perl array is used
601 instead of a hash table to keep track of retrieved objects, and
602 also because the image being smaller, less I/O function calls are

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

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

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

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

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

697 Forgot that AutoLoader does not export its own AUTOLOAD.
700 use AutoLoader 'AUTOLOAD';
702 but that would not be backward compatible. So the export is

707 Empty scalar strings are now "defined" at retrieval time.
709 New test to ensure an empty string is defined when retrieved.
711 Thu Feb 27 16:32:44 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
713 Updated version number
715 Declare VERSION as being used
717 Fixed a typo in the PerlIO_putc remapping.
718 PerlIO_read and perlIO_write inverted size/nb_items.
719 (only relevant for pre-perl5.004 versions)
721 Thu Feb 27 15:58:31 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
723 Updated version number
725 Added VERSION identification
727 Allow build with perl5.003, which is ante perlIO time
729 Mon Jan 13 17:53:18 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
733 Wed Jan 22 15:19:56 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
735 Updated version number in Makefile.PL.
737 Added "thanks to" section to README.
739 Documented new forgive_me variable.
743 Added forgive_me support to allow store() of data structures
744 containing non-storable items like CODE refs.
