5 1. Don't change the type of top level overloaded references to RV -
6 they are perfectly correct as PVMG
7 2. Storable needs to cope with incoming frozen data that happens to be
10 Wed Mar 17 15:40:29 GMT 2004 Nicholas Clark <nick@ccl4.org>
14 1. Add regression tests for the auto-require of STORABLE_thaw
15 2. Add auto-require of modules to restore overloading (and tests)
16 3. Change to no context (should give speedup with ithreads)
18 Sat Mar 13 20:11:03 GMT 2004 Nicholas Clark <nick@ccl4.org>
22 1. Storing restricted hashes in canonical order would SEGV. Fixed.
23 2. It was impossible to retrieve references to PL_sv_no and and
24 PL_sv_undef from STORABLE_thaw hooks.
25 3. restrict.t was failing on 5.8.0, due to 5.8.0's unique
26 implementation of restricted hashes using PL_sv_undef
27 4. These changes allow a space optimisation for restricted hashes.
29 Sat Jan 24 16:22:32 IST 2004 Abhijit Menon-Sen <ams@wiw.org>
33 1. Thread safety: Storable::CLONE/init_perlinterp() now create
34 a new Perl context for each new ithread.
35 (From Stas Bekman and Jan Dubois.)
36 2. Fix a tag count mismatch with $Storable::Deparse that caused
37 all back-references after a stored sub to be off-by-N (where
38 N was the number of code references in between).
40 3. Prevent CODE references from turning into SCALAR references.
43 Sat Jan 3 18:49:18 GMT 2004 Nicholas Clark <nick@ccl4.org>
47 Fix minor problems with the CPAN release
48 1: Make Storable.xs work on 5.8.2 and later (already in the core)
49 2: Ship the linux hints file
50 3: Ship Test::More for the benefit of Perls pre 5.6.2
51 4: Correct Makefile.PL to only install in core for 5.8.0 and later
53 Sat Sep 6 01:08:20 IST 2003 Abhijit Menon-Sen <ams@wiw.org>
57 This release works around a 5.8.0 bug which caused hashes to not
58 be marked as having key flags even though an HEK had HEK_WASUTF8
59 set. (Note that the only reasonable solution is to silently drop
60 the flag from the affected key.)
62 Users of RT 3 who were seeing assertion failures should upgrade.
63 (Perl 5.8.1 will have the bug fixed.)
65 Mon May 5 10:24:16 IST 2003 Abhijit Menon-Sen <ams@wiw.org>
69 Minor bugfixes (self-tied objects are now correctly stored, as
70 are the results of additions larger than INT_MAX).
72 Mon Oct 7 21:56:38 BST 2002 Nicholas Clark <nick@ccl4.org>
76 Remove qr// from t/downgrade.t so that it will run on 5.004
77 Mention $File::Spec::VERSION a second time in t/forgive.t so that it
78 runs without warnings in 5.004 (this may be a 5.00405 bug I'm working
80 Fix t/integer.t initialisation to actually generate 64 bits of 9c
81 Fix comparison tests to use eval to get around 64 bit IV conversion
82 issues on 5.6.x, following my t/integer.t ^ precedence bug found by
84 Alter t/malice.t to work with Test/More.pm in t/, and skip individual
85 subtests that use $Config{ptrsize}, so that the rest of the test can
87 Change t/malice.t and the error message in check_magic in Storable.xs
88 from "Pointer integer size" to "Pointer size"
89 Remove prerequisite of Test::More from Makefile.PL
90 Ship Test::Builder, Test::Simple and Test::More in t
92 Thu Oct 3 08:57:22 IST 2002 Abhijit Menon-Sen <ams@wiw.org>
96 Adds support for CODE references from Slaven Rezic
97 <slaven.rezic@berlin.de>.
99 Fri Jun 7 23:55:41 BST 2002 Nicholas Clark
103 Bug fix from Radu Greab <radu@netsoft.ro> (plus regression test)
104 to fix a recently introduced bug detected by Dave Rolsky.
105 Bug was that for a non threaded build, the class information was
106 being lost at freeze time on the first object with a STORABLE_freeze
107 hook. Consequentially the object was not blessed at all when thawed.
108 (The presence (or lack) of STORABLE_thaw was irrelevant; this was
109 a store-time data lost bug, caused by failure to initialize internal
111 The bug was introduced as development perl change 16442 (on
112 2002/05/07), so has been present since 2.00.
113 Patches to introduce more regression tests to reduce the chance of
114 a reoccurance of this sort of goof are always welcome.
116 Thu May 30 20:31:08 BST 2002 Nicholas Clark <nick@ccl4.org>
118 Version 2.03 Header changes on 5.6.x on Unix where IV is long long
120 5.6.x introduced the ability to have IVs as long long. However,
121 Configure still defined BYTEORDER based on the size of a long.
122 Storable uses the BYTEORDER value as part of the header, but
123 doesn't explicity store sizeof(IV) anywhere in the header.
124 Hence on 5.6.x built with IV as long long on a platform that
125 uses Configure (ie most things except VMS and Windows) headers
126 are identical for the different IV sizes, despite the files
127 containing some fields based on sizeof(IV)
129 5.8.0 is consistent; all platforms have BYTEORDER in config.h
130 based on sizeof(IV) rather than sizeof(long). This means that
131 the value of BYTEORDER will change from (say) 4321 to 87654321
132 between 5.6.1 and 5.8.0 built with the same options to Configure
133 on the same machine. This means that the Storable header will
134 differ, and the two versions will wrongly thing that they are
137 For the benefit of long term consistency, Storable now
138 implements the 5.8.0 BYTEORDER policy on 5.6.x. This means that
139 2.03 onwards default to be incompatible with 2.02 and earlier
140 (ie the large 1.0.x installed base) on the same 5.6.x perl.
142 To allow interworking, a new variable
143 $Storable::interwork_56_64bit is introduced. It defaults to
144 false. Set it to true to read and write old format files. Don't
145 use it unless you have existing stored data written with 5.6.x
146 that you couldn't otherwise read, or you need to interwork with
147 a machine running older Storable on a 5.6.x with long long IVs
148 (i.e., you probably don't need to use it).
150 Sat May 25 22:38:39 BST 2002 Nicholas Clark <nick@ccl4.org>
154 Rewrite Storable.xs so that the file header structure for write_magic
155 is built at compile time, and check_magic attempts to the header in
156 blocks rather than byte per byte. These changes make the compiled
157 extension 2.25% smaller, but are not significant enough to give a
160 Thu May 23 22:50:41 BST 2002 Nicholas Clark <nick@ccl4.org>
164 - New regression tests integer.t
165 - Add code to safely store large unsigned integers.
166 - Change code not to attempt to store large integers (ie > 32 bits)
167 in network order as 32 bits.
169 *Never* underestimate the value of a pathological test suite carefully
170 crafted with maximum malice before writing a line of real code. It
171 prevents crafty bugs from stowing away in your released code.
172 It's much less embarrassing to find them before you ship.
173 (Well, never underestimate it if you ever want to work for me)
175 Fri May 17 22:48:59 BST 2002 Nicholas Clark <nick@ccl4.org>
177 Version 2.0, binary format 2.5 (but writes format 2.4 on pre 5.7.3)
179 The perl5 porters have decided to make sure that Storable still
180 builds on pre-5.8 perls, and make the 5.8 version available on CPAN.
181 The VERSION is now 2.0, and it passes all tests on 5.005_03, 5.6.1
182 and 5.6.1 with threads. On 5.6.0 t/downgrade.t fails tests 34 and 37,
183 due to a bug in 5.6.0 - upgrade to 5.6.1.
185 Jarkko and I have collated the list of changes the perl5 porters have
186 from the perl5 Changes file:
188 - data features of upcoming perl 5.8.0 are supported: Unicode hash
189 keys (Unicode hash values have been supported since Storable 1.0.1)
190 and "restricted hashes" (readonly hashes and hash entries)
191 - a newer version of perl can now be used to serialize data which is
192 not supported in earlier perls: Storable will attempt to do the
193 right thing for as long as possible, croaking only when safe data
194 conversion simply isn't possible. Alternatively earlier perls can
195 opt to have a lossy downgrade data instead of croaking
196 - when built with perls pre 5.7.3 this Storable writes out files
197 with binary format 2.4, the same format as Storable 1.0.8 onwards.
198 This should mean that this Storable will inter-operate seamlessly
199 with any Storable 1.0.8 or newer on perls pre 5.7.3
200 - dclone() now works with empty string scalar objects
201 - retrieving of large hashes is now more efficient
202 - more routines autosplit out of the main module, so Storable should
203 load slightly more quickly
204 - better documentation
205 - the internal context objects are now freed explicitly, rather than
206 relying on thread or process exit
207 - bugs fixed in debugging trace code affecting builds made with 64 bit
209 - code tidy-ups to allow clean compiles with more warning options
210 turned on avoid problems with $@ getting corrupted on 5.005_03 if
211 Carp wasn't already loaded
212 - added &show_file_magic, so you can add to /etc/magic and teach
213 Unix's file command about Storable files
215 We plan to keep Storable on CPAN in sync with the Perl core, so
216 if you encounter bugs or other problems building or using Storable,
217 please let us know at perl5-porters@perl.org
220 Sat Dec 1 14:37:54 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
222 This is the LAST maintenance release of the Storable module.
223 Indeed, Storable is now part of perl 5.8, and will be maintained
224 as part of Perl. The CPAN module will remain available there
225 for people running pre-5.8 perls.
227 Avoid requiring Fcntl upfront, useful to embedded runtimes.
228 Use an eval {} for testing, instead of making Storable.pm
229 simply fail its compilation in the BEGIN block.
231 store_fd() will now correctly autoflush file if needed.
233 Tue Aug 28 23:53:20 MEST 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
235 Fixed truncation race with lock_retrieve() in lock_store().
236 The file has to be truncated only once the exclusive lock is held.
238 Removed spurious debugging messages in .xs file.
240 Sun Jul 1 13:27:32 MEST 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
242 Systematically use "=over 4" for POD linters.
243 Apparently, POD linters are much stricter than would
244 otherwise be needed, but that's OK.
246 Fixed memory corruption on croaks during thaw(). Thanks
247 to Claudio Garcia for reproducing this bug and providing the
248 code to exercise it. Added test cases for this bug, adapted
251 Made code compile cleanly with -Wall (from Jarkko Hietaniemi).
253 Changed tagnum and classnum from I32 to IV in context. Also
256 Thu Mar 15 01:22:32 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
258 Last version was wrongly compiling with assertions on, due
259 to an edit glitch. That did not cause any problem (apart from
260 a slight performance loss) excepted on Win* platforms, where the
261 assertion code does not compile.
263 Sat Feb 17 13:37:37 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
267 Forgot to increase version number at previous patch (there were
268 two of them, which is why we jump from 1.0.8 to 1.0.10).
270 Sat Feb 17 13:35:00 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
272 Version 1.0.8, binary format 2.4.
274 Fixed incorrect error message.
276 Now bless objects ASAP at retrieve time, which is meant to fix
279 * Indirect references to overloaded object were not able to
280 restore overloading if the object was not blessed yet,
281 which was possible since blessing occurred only after the
284 * Storable hooks asking for serialization of blessed ref could
285 get un-blessed refs at retrieval time, for the very same
288 The fix implemented here was suggested by Nick Ing-Simmons.
290 Added support for blessed ref to tied structures. This is the
291 cause for the binary format change.
293 Added EBCDIC version of the compatibility test with 0.6.11,
296 Added tests for the new features, and to make sure the bugs they
297 are meant to fix are indeed fixed.
299 Wed Jan 3 10:43:18 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
301 Removed spurious 'clean' entry in Makefile.PL.
303 Added CAN_FLOCK to determine whether we can flock() or not,
304 by inspecting Perl's configuration parameters, as determined
307 Trace offending package when overloading cannot be restored
310 Made context cleanup safer to avoid dup freeing, mostly in the
311 presence of repeated exceptions during store/retrieve (which can
312 cause memory leaks anyway, so it's just additional safety, not a
315 Sun Nov 5 18:23:48 MET 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
319 Fixed severe "object lost" bug for STORABLE_freeze returns,
320 when refs to lexicals, taken within the hook, were to be
321 serialized by Storable. Enhanced the t/recurse.t test to
322 stress hook a little more with refs to lexicals.
324 Thu Oct 26 19:14:38 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
328 Documented that store() and retrieve() can return undef.
329 That is, the error reporting is not always made via exceptions,
330 as the paragraph on error reporting was implying.
332 Auto requires module of blessed ref when STORABLE_thaw misses.
333 When the Storable engine looks for the STORABLE_thaw hook and
334 does not find it, it now tries to require the package into which
335 the blessed reference is.
337 Just check $^O, in t/lock.t: there's no need to pull the whole
338 Config module for that.
340 Mon Oct 23 20:03:49 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
344 Protected calls to flock() for DOS platform: apparently, the
345 flock/fcnlt emulation is reported to be broken on that
348 Added logcarp emulation if they don't have Log::Agent, since
349 we now use it to carp when lock_store/lock_retrieve is used
352 Fri Sep 29 21:52:29 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
356 Avoid using "tainted" and "dirty" since Perl remaps them via
357 cpp (i.e. #define). This is deeply harmful when threading
358 is enabled. This concerned both the context structure and
359 local variable and argument names. Brrr..., scary!
361 Thu Sep 28 23:46:39 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
365 Fixed spelling in README.
367 Added lock_store, lock_nstore, and lock_retrieve (advisory locking)
368 after a proposal from Erik Haugan <erik@solbors.no>.
370 Perls before 5.004_04 lack newSVpvn, added remapping in XS.
372 Fixed stupid typo in the t/utf8.t test.
374 Sun Sep 17 18:51:10 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
376 Version 1.0.1, binary format 2.3.
378 Documented that doubles are stored stringified by nstore().
380 Added Salvador Ortiz Garcia in CREDITS section, He identified
381 a bug in the store hooks and proposed the right fix: the class
382 id was allocated too soon. His bug case was also added to
383 the regression test suite.
385 Now only taint retrieved data when source was tainted. A bug
386 discovered by Marc Lehmann.
388 Added support for UTF-8 strings, a contribution of Marc Lehmann.
389 This is normally only activated in post-5.6 perls.
391 Thu Aug 31 23:06:06 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
393 First official release Storable 1.0, for inclusion in perl 5.7.0.
394 The license scheme is now compatible with Perl's.
396 Thu Aug 24 01:02:02 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
398 ANSI-fied most of the code, preparing for Perl core integration.
399 The next version of Storable will be 0.8, and will be integrated
400 into the Perl core (development branch).
402 Dispatch tables were moved upfront to relieve some compilers,
403 especially on AIX and Windows platforms.
405 Merged 64-bit fixes from perl5-porters.
407 Mon Aug 14 09:22:04 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
409 Added a refcnt dec in retrieve_tied_key(): sv_magic() increases
410 the refcnt on the mg_ptr as well.
412 Removed spurious dependency to Devel::Peek, which was used for
413 testing only in t/tied_items.t. Thanks to Conrad Heiney
414 <conrad@fringehead.org> for spotting it first.
416 Sun Aug 13 22:12:59 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
418 Marc Lehmann kindly contributed code to add overloading support
419 and to handle references to tied variables.
421 Rewrote leading blurb about compatibility to make it clearer what
422 "backward compatibility" is about: when I say 0.7 is backward
423 compatible with 0.6, it means the revision 0.7 can read files
426 Mention new Clone(3) extension in SEE ALSO.
428 Was wrongly optimizing for "undef" values in hashes by not
429 fully recursing: as a result, tied "undef" values were incorrectly
432 Sun Jul 30 12:59:17 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
434 First revision of Storable 0.7.
436 The serializing format is new, known as version 2.0. It is fully
437 backward compatible with 0.6. Earlier formats are deprecated and
438 have not even been tested: next version will drop pre-0.6 format.
440 Changes since 0.6@11:
442 - Moved interface to the "beta" status. Some tiny parts are still
443 subject to change, but nothing important enough to warrant an "alpha"
446 - Slightly reduced the size of the Storable image by factorizing
447 object class names and removing final object storage notification due
448 to a redesign of the blessed object storing.
450 - Classes can now redefine how they wish their instances to be serialized
451 and/or deep cloned. Serializing hooks are written in Perl code.
453 - The engine is now fully re-entrant.
455 Sun Apr 2 23:47:50 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
457 Added provision to detect more recent binary formats, since
458 the new upcoming Storable-0.7 will use a different format.
459 In order to prevent attempting the de-serialization of newer
460 formats by older versions, I'm adding this now to the 0.6 series.
462 I'm expecting this revision to be the last of the 0.6 series.
463 Unless it does not work with perl 5.6, which I don't use yet,
464 and therefore against which I cannot test.
466 Wed Mar 29 19:55:21 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
468 Added note about format incompatibilities with old versions
469 (i.e. pre 0.5@9 formats, which cannot be understood as there
470 was no versionning information in the file by then).
472 Protect all $@ variables when eval {} used, to avoid corrupting
473 it when store/retrieve is called within an exception handler.
475 Mistakenly included "patchlevel.h" instead of <patchlevel.h>,
476 preventing Perl's patchlevel from being included, which is
477 needed starting from 5.6.
479 Tue May 12 09:15:15 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
481 Fixed shared "undef" bug in hashes, which did not remain shared
482 through store/retrieve.
484 Thu Feb 10 19:48:16 MET 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
486 added last_op_in_netorder() predicate
487 documented last_op_in_netorder()
488 added tests for the new last_op_in_netorder() predicate
490 Wed Oct 20 19:07:36 MEST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
492 Forgot to update VERSION
494 Tue Oct 19 21:25:02 MEST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
496 Added mention of japanese translation for the manual page.
498 Fixed typo in macro that made threaded code not compilable,
499 especially on Win32 platforms.
501 Changed detection of older perls (pre-5.005) by testing PATCHLEVEL
502 directly instead of relying on internal symbols.
504 Tue Sep 14 22:13:28 MEST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
506 Integrated "thread-safe" patch from Murray Nesbitt.
507 Note that this may not be very efficient for threaded code,
508 see comment in the code.
510 Try to avoid compilation warning on 64-bit CPUs. Can't test it,
511 since I don't have access to such machines.
513 Mon Jul 12 14:37:19 METDST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
515 changed my e-mail to pobox.
517 mentionned it is not thread-safe.
519 updated version number.
521 uses new internal PL_* naming convention.
523 Fri Jul 3 13:38:16 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
525 Updated benchmark figures due to recent optimizations done in
526 store(): tagnums are now stored as-is in the hash table, so
527 no surrounding SV is created. And the "shared keys" mode for
528 hash table was turned off.
530 Fixed backward compatibility (wrt 0.5@9) for retrieval of
531 blessed refs. That old version did something wrong, but the
532 bugfix prevented correct retrieval of the old format.
534 Mon Jun 22 11:00:48 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
536 Changed benchmark figures.
538 Adjust refcnt of tied objects after calling sv_magic() to avoid
539 memory leaks. Contributed by Jeff Gresham.
541 Fri Jun 12 11:50:04 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
543 Added workaround for persistent LVALUE-ness in perl5.004. All
544 scalars tagged as being an lvalue are handled as if they were
545 not an lvalue at all. Added test for that LVALUE bug workaround.
547 Now handles Perl immortal scalars explicitely, by storing &sv_yes
548 as such, explicitely.
550 Retrieval of non-immortal undef cannot be shared. Previous
551 version was over-optimizing by not creating a separate SV for
552 all undefined scalars seen.
554 Thu Jun 4 17:21:51 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
556 Baseline for Storable-0.6@0.
558 This version introduces a binary incompatibility in the generated
559 binary image, which is more compact than older ones by approximatively
560 15%, depending on the exact degree of sharing in your structures.
562 The good news is that your older images can still be retrieved with
563 this version, i.e. backward compatibility is preserved. This version
564 of Storable can only generate new binaries however.
566 Another good news is that the retrieval of data structure is
567 significantly quicker than before, because a Perl array is used
568 instead of a hash table to keep track of retrieved objects, and
569 also because the image being smaller, less I/O function calls are
572 Tue May 12 09:15:15 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
574 Version number now got from Storable.pm directly.
576 Fixed overzealous sv_type() optimization, which would make
577 Storable fail when faced with an "upgraded" SV to the PVIV
578 or PVNV kind containing a reference.
580 Thu Apr 30 15:11:30 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
582 Extended the SYNOPSIS section to give quick overview of the
583 routines and their signature.
585 Optimized sv_type() to avoid flags checking when not needed, i.e.
586 when their type makes it impossible for them to be refs or tied.
587 This slightly increases throughput by a few percents when refs
588 and tied variables are marginal occurrences in your data.
590 Stubs for XS now use OutputStream and InputStream file types to
591 make it work when the given file is actually a socket. Perl
592 makes a distinction for sockets in its internal I/O structures
593 by having both a read and a write structure, whereas plain files

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

604 I said SvPOK() had changed to SvPOKp(), but that was a lie...

608 Wrote sizeof(SV *) instead of sizeof(I32) when portable, which
609 in effect mangled the object tags and prevented portability
610 accross 32/64 bit architectures!

614 Added code example for store_fd() and retrieve_fd() in the
615 man page, to emphasize that file descriptors must be passed as
616 globs, not as plain strings.
618 Cannot use SV addresses as tag when using nstore() on LP64. This
619 was the cause of problems when creating a storable image on an
620 LP64 machine and retrieving it on an ILP32 system, which is
621 exactly what nstore() is meant for...
623 However, we continue to use SV addresses as tags for plain store(),
624 because benchamarking shows that it saves up to 8% of the store
625 time, and store() is meant to be fast at the expense of lack
628 This means there will be approximately an 8% degradation of
629 performance for nstore(), but it's now working as expected.
630 That cost may vary on your machine of course, since it is
631 solely caused by the memory allocation overhead used to create
632 unique SV tags for each distinct stored SV.

636 Don't use any '_' in version number.
638 Tue Jan 13 17:51:50 MET 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
640 Updated version number.
642 added binmode() calls for systems where it matters.
644 Be sure to pass globs, not plain file strings, to C routines,
645 so that Storable can be used under the Perl debugger.

649 Fix memory leaks on seen hash table and returned SV refs.
651 Storable did not work properly when tainting enabled.
653 Fixed "Allocation too large" messages in freeze/thaw and added.
654 proper regression test in t/freeze.t.

664 Forgot that AutoLoader does not export its own AUTOLOAD.
667 use AutoLoader 'AUTOLOAD';
669 but that would not be backward compatible. So the export is

674 Empty scalar strings are now "defined" at retrieval time.
676 New test to ensure an empty string is defined when retrieved.
678 Thu Feb 27 16:32:44 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
680 Updated version number
682 Declare VERSION as being used
684 Fixed a typo in the PerlIO_putc remapping.
685 PerlIO_read and perlIO_write inverted size/nb_items.
686 (only relevant for pre-perl5.004 versions)
688 Thu Feb 27 15:58:31 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
690 Updated version number
