39 Bug fix from Radu Greab <radu@netsoft.ro> (plus regression test)
40 to fix a recently introduced bug detected by Dave Rolsky.
41 Bug was that for a non threaded build, the class information was
42 being lost at freeze time on the first object with a STORABLE_freeze
43 hook. Consequentially the object was not blessed at all when thawed.
44 (The presence (or lack) of STORABLE_thaw was irrelevant; this was
45 a store-time data lost bug, caused by failure to initialize internal
47 The bug was introduced as development perl change 16442 (on
48 2002/05/07), so has been present since 2.00.
49 Patches to introduce more regression tests to reduce the chance of
50 a reoccurance of this sort of goof are always welcome.

54 Version 2.03 Header changes on 5.6.x on Unix where IV is long long
56 5.6.x introduced the ability to have IVs as long long. However,
57 Configure still defined BYTEORDER based on the size of a long.
58 Storable uses the BYTEORDER value as part of the header, but
59 doesn't explicity store sizeof(IV) anywhere in the header.
60 Hence on 5.6.x built with IV as long long on a platform that
61 uses Configure (ie most things except VMS and Windows) headers
62 are identical for the different IV sizes, despite the files
63 containing some fields based on sizeof(IV)
65 5.8.0 is consistent; all platforms have BYTEORDER in config.h
66 based on sizeof(IV) rather than sizeof(long). This means that
67 the value of BYTEORDER will change from (say) 4321 to 87654321
68 between 5.6.1 and 5.8.0 built with the same options to Configure
69 on the same machine. This means that the Storable header will
70 differ, and the two versions will wrongly thing that they are
73 For the benefit of long term consistency, Storable now
74 implements the 5.8.0 BYTEORDER policy on 5.6.x. This means that
75 2.03 onwards default to be incompatible with 2.02 and earlier
76 (ie the large 1.0.x installed base) on the same 5.6.x perl.
78 To allow interworking, a new variable
79 $Storable::interwork_56_64bit is introduced. It defaults to
80 false. Set it to true to read and write old format files. Don't
81 use it unless you have existing stored data written with 5.6.x
82 that you couldn't otherwise read, or you need to interwork with
83 a machine running older Storable on a 5.6.x with long long IVs
84 (i.e., you probably don't need to use it).
86 Sat May 25 22:38:39 BST 2002 Nicholas Clark <nick@ccl4.org>
90 Rewrite Storable.xs so that the file header structure for write_magic
91 is built at compile time, and check_magic attempts to the header in
92 blocks rather than byte per byte. These changes make the compiled
93 extension 2.25% smaller, but are not significant enough to give a
96 Thu May 23 22:50:41 BST 2002 Nicholas Clark <nick@ccl4.org>
100 - New regression tests integer.t
101 - Add code to safely store large unsigned integers.
102 - Change code not to attempt to store large integers (ie > 32 bits)
103 in network order as 32 bits.
105 *Never* underestimate the value of a pathological test suite carefully
106 crafted with maximum malice before writing a line of real code. It
107 prevents crafty bugs from stowing away in your released code.
108 It's much less embarrassing to find them before you ship.
109 (Well, never underestimate it if you ever want to work for me)

113 Version 2.0, binary format 2.5 (but writes format 2.4 on pre 5.7.3)
115 The perl5 porters have decided to make sure that Storable still
116 builds on pre-5.8 perls, and make the 5.8 version available on CPAN.
117 The VERSION is now 2.0, and it passes all tests on 5.005_03, 5.6.1
118 and 5.6.1 with threads. On 5.6.0 t/downgrade.t fails tests 34 and 37,
119 due to a bug in 5.6.0 - upgrade to 5.6.1.
121 Jarkko and I have collated the list of changes the perl5 porters have
122 from the perl5 Changes file:
124 - data features of upcoming perl 5.8.0 are supported: Unicode hash
125 keys (Unicode hash values have been supported since Storable 1.0.1)
126 and "restricted hashes" (readonly hashes and hash entries)
127 - a newer version of perl can now be used to serialize data which is
128 not supported in earlier perls: Storable will attempt to do the
129 right thing for as long as possible, croaking only when safe data
130 conversion simply isn't possible. Alternatively earlier perls can
131 opt to have a lossy downgrade data instead of croaking
132 - when built with perls pre 5.7.3 this Storable writes out files
133 with binary format 2.4, the same format as Storable 1.0.8 onwards.
134 This should mean that this Storable will inter-operate seamlessly
135 with any Storable 1.0.8 or newer on perls pre 5.7.3
136 - dclone() now works with empty string scalar objects
137 - retrieving of large hashes is now more efficient
138 - more routines autosplit out of the main module, so Storable should
139 load slightly more quickly
140 - better documentation
141 - the internal context objects are now freed explicitly, rather than
142 relying on thread or process exit
143 - bugs fixed in debugging trace code affecting builds made with 64 bit
145 - code tidy-ups to allow clean compiles with more warning options
146 turned on avoid problems with $@ getting corrupted on 5.005_03 if
147 Carp wasn't already loaded
148 - added &show_file_magic, so you can add to /etc/magic and teach
149 Unix's file command about Storable files
151 We plan to keep Storable on CPAN in sync with the Perl core, so
152 if you encounter bugs or other problems building or using Storable,
153 please let us know at perl5-porters@perl.org

158 This is the LAST maintenance release of the Storable module.
159 Indeed, Storable is now part of perl 5.8, and will be maintained
160 as part of Perl. The CPAN module will remain available there
161 for people running pre-5.8 perls.
163 Avoid requiring Fcntl upfront, useful to embedded runtimes.
164 Use an eval {} for testing, instead of making Storable.pm
165 simply fail its compilation in the BEGIN block.
167 store_fd() will now correctly autoflush file if needed.
169 Tue Aug 28 23:53:20 MEST 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
171 Fixed truncation race with lock_retrieve() in lock_store().
172 The file has to be truncated only once the exclusive lock is held.
174 Removed spurious debugging messages in .xs file.
176 Sun Jul 1 13:27:32 MEST 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
178 Systematically use "=over 4" for POD linters.
179 Apparently, POD linters are much stricter than would
180 otherwise be needed, but that's OK.
182 Fixed memory corruption on croaks during thaw(). Thanks
183 to Claudio Garcia for reproducing this bug and providing the
184 code to exercise it. Added test cases for this bug, adapted
187 Made code compile cleanly with -Wall (from Jarkko Hietaniemi).
189 Changed tagnum and classnum from I32 to IV in context. Also
192 Thu Mar 15 01:22:32 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
194 Last version was wrongly compiling with assertions on, due
195 to an edit glitch. That did not cause any problem (apart from
196 a slight performance loss) excepted on Win* platforms, where the
197 assertion code does not compile.
199 Sat Feb 17 13:37:37 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
203 Forgot to increase version number at previous patch (there were
204 two of them, which is why we jump from 1.0.8 to 1.0.10).
206 Sat Feb 17 13:35:00 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
208 Version 1.0.8, binary format 2.4.
210 Fixed incorrect error message.
212 Now bless objects ASAP at retrieve time, which is meant to fix
215 * Indirect references to overloaded object were not able to
216 restore overloading if the object was not blessed yet,
217 which was possible since blessing occurred only after the
220 * Storable hooks asking for serialization of blessed ref could
221 get un-blessed refs at retrieval time, for the very same
224 The fix implemented here was suggested by Nick Ing-Simmons.
226 Added support for blessed ref to tied structures. This is the
227 cause for the binary format change.
229 Added EBCDIC version of the compatibility test with 0.6.11,
232 Added tests for the new features, and to make sure the bugs they
233 are meant to fix are indeed fixed.
235 Wed Jan 3 10:43:18 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
237 Removed spurious 'clean' entry in Makefile.PL.
239 Added CAN_FLOCK to determine whether we can flock() or not,
240 by inspecting Perl's configuration parameters, as determined
243 Trace offending package when overloading cannot be restored
246 Made context cleanup safer to avoid dup freeing, mostly in the
247 presence of repeated exceptions during store/retrieve (which can
248 cause memory leaks anyway, so it's just additional safety, not a
251 Sun Nov 5 18:23:48 MET 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
255 Fixed severe "object lost" bug for STORABLE_freeze returns,
256 when refs to lexicals, taken within the hook, were to be
257 serialized by Storable. Enhanced the t/recurse.t test to
258 stress hook a little more with refs to lexicals.
260 Thu Oct 26 19:14:38 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
264 Documented that store() and retrieve() can return undef.
265 That is, the error reporting is not always made via exceptions,
266 as the paragraph on error reporting was implying.
268 Auto requires module of blessed ref when STORABLE_thaw misses.
269 When the Storable engine looks for the STORABLE_thaw hook and
270 does not find it, it now tries to require the package into which
271 the blessed reference is.
273 Just check $^O, in t/lock.t: there's no need to pull the whole
274 Config module for that.
276 Mon Oct 23 20:03:49 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
280 Protected calls to flock() for DOS platform: apparently, the
281 flock/fcnlt emulation is reported to be broken on that
284 Added logcarp emulation if they don't have Log::Agent, since
285 we now use it to carp when lock_store/lock_retrieve is used
288 Fri Sep 29 21:52:29 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
292 Avoid using "tainted" and "dirty" since Perl remaps them via
293 cpp (i.e. #define). This is deeply harmful when threading
294 is enabled. This concerned both the context structure and
295 local variable and argument names. Brrr..., scary!
297 Thu Sep 28 23:46:39 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
301 Fixed spelling in README.
303 Added lock_store, lock_nstore, and lock_retrieve (advisory locking)
304 after a proposal from Erik Haugan <erik@solbors.no>.
306 Perls before 5.004_04 lack newSVpvn, added remapping in XS.
308 Fixed stupid typo in the t/utf8.t test.
310 Sun Sep 17 18:51:10 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
312 Version 1.0.1, binary format 2.3.
314 Documented that doubles are stored stringified by nstore().
316 Added Salvador Ortiz Garcia in CREDITS section, He identified
317 a bug in the store hooks and proposed the right fix: the class
318 id was allocated too soon. His bug case was also added to
319 the regression test suite.
321 Now only taint retrieved data when source was tainted. A bug
322 discovered by Marc Lehmann.
324 Added support for UTF-8 strings, a contribution of Marc Lehmann.
325 This is normally only activated in post-5.6 perls.
327 Thu Aug 31 23:06:06 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
329 First official release Storable 1.0, for inclusion in perl 5.7.0.
330 The license scheme is now compatible with Perl's.
332 Thu Aug 24 01:02:02 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
334 ANSI-fied most of the code, preparing for Perl core integration.
335 The next version of Storable will be 0.8, and will be integrated
336 into the Perl core (development branch).
338 Dispatch tables were moved upfront to relieve some compilers,
339 especially on AIX and Windows platforms.
341 Merged 64-bit fixes from perl5-porters.
343 Mon Aug 14 09:22:04 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
345 Added a refcnt dec in retrieve_tied_key(): sv_magic() increases
346 the refcnt on the mg_ptr as well.
348 Removed spurious dependency to Devel::Peek, which was used for
349 testing only in t/tied_items.t. Thanks to Conrad Heiney
350 <conrad@fringehead.org> for spotting it first.
352 Sun Aug 13 22:12:59 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
354 Marc Lehmann kindly contributed code to add overloading support
355 and to handle references to tied variables.
357 Rewrote leading blurb about compatibility to make it clearer what
358 "backward compatibility" is about: when I say 0.7 is backward
359 compatible with 0.6, it means the revision 0.7 can read files
362 Mention new Clone(3) extension in SEE ALSO.
364 Was wrongly optimizing for "undef" values in hashes by not
365 fully recursing: as a result, tied "undef" values were incorrectly
368 Sun Jul 30 12:59:17 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
370 First revision of Storable 0.7.
372 The serializing format is new, known as version 2.0. It is fully
373 backward compatible with 0.6. Earlier formats are deprecated and
374 have not even been tested: next version will drop pre-0.6 format.
376 Changes since 0.6@11:
378 - Moved interface to the "beta" status. Some tiny parts are still
379 subject to change, but nothing important enough to warrant an "alpha"
382 - Slightly reduced the size of the Storable image by factorizing
383 object class names and removing final object storage notification due
384 to a redesign of the blessed object storing.
386 - Classes can now redefine how they wish their instances to be serialized
387 and/or deep cloned. Serializing hooks are written in Perl code.
389 - The engine is now fully re-entrant.
391 Sun Apr 2 23:47:50 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
393 Added provision to detect more recent binary formats, since
394 the new upcoming Storable-0.7 will use a different format.
395 In order to prevent attempting the de-serialization of newer
396 formats by older versions, I'm adding this now to the 0.6 series.
398 I'm expecting this revision to be the last of the 0.6 series.
399 Unless it does not work with perl 5.6, which I don't use yet,
400 and therefore against which I cannot test.
402 Wed Mar 29 19:55:21 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
404 Added note about format incompatibilities with old versions
405 (i.e. pre 0.5@9 formats, which cannot be understood as there
406 was no versionning information in the file by then).
408 Protect all $@ variables when eval {} used, to avoid corrupting
409 it when store/retrieve is called within an exception handler.
411 Mistakenly included "patchlevel.h" instead of <patchlevel.h>,
412 preventing Perl's patchlevel from being included, which is
413 needed starting from 5.6.
415 Tue May 12 09:15:15 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
417 Fixed shared "undef" bug in hashes, which did not remain shared
418 through store/retrieve.
420 Thu Feb 10 19:48:16 MET 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
422 added last_op_in_netorder() predicate
423 documented last_op_in_netorder()
424 added tests for the new last_op_in_netorder() predicate
426 Wed Oct 20 19:07:36 MEST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
428 Forgot to update VERSION
430 Tue Oct 19 21:25:02 MEST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
432 Added mention of japanese translation for the manual page.
434 Fixed typo in macro that made threaded code not compilable,
435 especially on Win32 platforms.
437 Changed detection of older perls (pre-5.005) by testing PATCHLEVEL
438 directly instead of relying on internal symbols.
440 Tue Sep 14 22:13:28 MEST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
442 Integrated "thread-safe" patch from Murray Nesbitt.
443 Note that this may not be very efficient for threaded code,
444 see comment in the code.
446 Try to avoid compilation warning on 64-bit CPUs. Can't test it,
447 since I don't have access to such machines.
449 Mon Jul 12 14:37:19 METDST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
451 changed my e-mail to pobox.
453 mentionned it is not thread-safe.
455 updated version number.
457 uses new internal PL_* naming convention.
459 Fri Jul 3 13:38:16 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
461 Updated benchmark figures due to recent optimizations done in
462 store(): tagnums are now stored as-is in the hash table, so
463 no surrounding SV is created. And the "shared keys" mode for
464 hash table was turned off.
466 Fixed backward compatibility (wrt 0.5@9) for retrieval of
467 blessed refs. That old version did something wrong, but the
468 bugfix prevented correct retrieval of the old format.
470 Mon Jun 22 11:00:48 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
472 Changed benchmark figures.
474 Adjust refcnt of tied objects after calling sv_magic() to avoid
475 memory leaks. Contributed by Jeff Gresham.
477 Fri Jun 12 11:50:04 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
479 Added workaround for persistent LVALUE-ness in perl5.004. All
480 scalars tagged as being an lvalue are handled as if they were
481 not an lvalue at all. Added test for that LVALUE bug workaround.
483 Now handles Perl immortal scalars explicitely, by storing &sv_yes
484 as such, explicitely.
486 Retrieval of non-immortal undef cannot be shared. Previous
487 version was over-optimizing by not creating a separate SV for
488 all undefined scalars seen.
490 Thu Jun 4 17:21:51 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
492 Baseline for Storable-0.6@0.
494 This version introduces a binary incompatibility in the generated
495 binary image, which is more compact than older ones by approximatively
496 15%, depending on the exact degree of sharing in your structures.
498 The good news is that your older images can still be retrieved with
499 this version, i.e. backward compatibility is preserved. This version
500 of Storable can only generate new binaries however.
502 Another good news is that the retrieval of data structure is
503 significantly quicker than before, because a Perl array is used
504 instead of a hash table to keep track of retrieved objects, and
505 also because the image being smaller, less I/O function calls are
508 Tue May 12 09:15:15 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
510 Version number now got from Storable.pm directly.
512 Fixed overzealous sv_type() optimization, which would make
513 Storable fail when faced with an "upgraded" SV to the PVIV
514 or PVNV kind containing a reference.
516 Thu Apr 30 15:11:30 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
518 Extended the SYNOPSIS section to give quick overview of the
519 routines and their signature.
521 Optimized sv_type() to avoid flags checking when not needed, i.e.
522 when their type makes it impossible for them to be refs or tied.
523 This slightly increases throughput by a few percents when refs
524 and tied variables are marginal occurrences in your data.
526 Stubs for XS now use OutputStream and InputStream file types to
527 make it work when the given file is actually a socket. Perl
528 makes a distinction for sockets in its internal I/O structures
529 by having both a read and a write structure, whereas plain files
532 Tue Jun 3 09:41:33 METDST 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
534 Thanks to a contribution from Benjamin A. Holzman, Storable is now
535 able to correctly serialize tied SVs, i.e. tied arrays, hashes
538 Thu Apr 9 18:07:51 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
540 I said SvPOK() had changed to SvPOKp(), but that was a lie...
542 Wed Apr 8 13:14:29 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
544 Wrote sizeof(SV *) instead of sizeof(I32) when portable, which
545 in effect mangled the object tags and prevented portability
546 accross 32/64 bit architectures!
548 Wed Mar 25 14:57:02 MET 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
550 Added code example for store_fd() and retrieve_fd() in the
551 man page, to emphasize that file descriptors must be passed as
552 globs, not as plain strings.
554 Cannot use SV addresses as tag when using nstore() on LP64. This
555 was the cause of problems when creating a storable image on an
556 LP64 machine and retrieving it on an ILP32 system, which is
557 exactly what nstore() is meant for...
559 However, we continue to use SV addresses as tags for plain store(),
560 because benchamarking shows that it saves up to 8% of the store
561 time, and store() is meant to be fast at the expense of lack
564 This means there will be approximately an 8% degradation of
565 performance for nstore(), but it's now working as expected.
566 That cost may vary on your machine of course, since it is
567 solely caused by the memory allocation overhead used to create
568 unique SV tags for each distinct stored SV.

574 Tue Jan 13 17:51:50 MET 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
576 Updated version number.
578 added binmode() calls for systems where it matters.
580 Be sure to pass globs, not plain file strings, to C routines,
581 so that Storable can be used under the Perl debugger.
583 Wed Nov 5 10:53:22 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
585 Fix memory leaks on seen hash table and returned SV refs.
587 Storable did not work properly when tainting enabled.
