1 root 1.1 Thu Jun 17 12:26:43 BST 2004 Nicholas Clark <nick@ccl4.org>
2    
3     Version 2.13
4    
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
8     utf8 encoded.
9    
10     Wed Mar 17 15:40:29 GMT 2004 Nicholas Clark <nick@ccl4.org>
11    
12     Version 2.12
13    
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)
17    
18     Sat Mar 13 20:11:03 GMT 2004 Nicholas Clark <nick@ccl4.org>
19    
20     Version 2.11
21    
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.
28    
29     Sat Jan 24 16:22:32 IST 2004 Abhijit Menon-Sen <ams@wiw.org>
30    
31     Version 2.10
32    
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).
39     (From Sam Vilain.)
40     3. Prevent CODE references from turning into SCALAR references.
41     (From Slaven Rezic.)
42    
43     Sat Jan 3 18:49:18 GMT 2004 Nicholas Clark <nick@ccl4.org>
44    
45     Version 2.09
46    
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
52    
53     Sat Sep 6 01:08:20 IST 2003 Abhijit Menon-Sen <ams@wiw.org>
54    
55     Version 2.08
56    
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.)
61    
62     Users of RT 3 who were seeing assertion failures should upgrade.
63     (Perl 5.8.1 will have the bug fixed.)
64    
65     Mon May 5 10:24:16 IST 2003 Abhijit Menon-Sen <ams@wiw.org>
66    
67     Version 2.07
68    
69     Minor bugfixes (self-tied objects are now correctly stored, as
70     are the results of additions larger than INT_MAX).
71    
72     Mon Oct 7 21:56:38 BST 2002 Nicholas Clark <nick@ccl4.org>
73    
74     Version 2.06
75    
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
79     round)
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
83     Rafael Garcia-Suarez
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
86     now be run with 5.004
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
91    
92     Thu Oct 3 08:57:22 IST 2002 Abhijit Menon-Sen <ams@wiw.org>
93    
94     Version 2.05
95    
96     Adds support for CODE references from Slaven Rezic
97     <slaven.rezic@berlin.de>.
98    
99     Fri Jun 7 23:55:41 BST 2002 Nicholas Clark
100    
101     Version 2.04
102    
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
110     context)
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.
115    
116     Thu May 30 20:31:08 BST 2002 Nicholas Clark <nick@ccl4.org>
117    
118     Version 2.03 Header changes on 5.6.x on Unix where IV is long long
119    
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)
128    
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
135     incompatible.
136    
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.
141    
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).
149    
150     Sat May 25 22:38:39 BST 2002 Nicholas Clark <nick@ccl4.org>
151    
152     Version 2.02
153    
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
158     noticeable speed up.
159    
160     Thu May 23 22:50:41 BST 2002 Nicholas Clark <nick@ccl4.org>
161    
162     Version 2.01
163    
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.
168    
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)
174    
175     Fri May 17 22:48:59 BST 2002 Nicholas Clark <nick@ccl4.org>
176    
177     Version 2.0, binary format 2.5 (but writes format 2.4 on pre 5.7.3)
178    
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.
184    
185     Jarkko and I have collated the list of changes the perl5 porters have
186     from the perl5 Changes file:
187    
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
208     IVs
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
214    
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
218     Patches welcome!
219    
220     Sat Dec 1 14:37:54 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
221    
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.
226    
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.
230    
231     store_fd() will now correctly autoflush file if needed.
232    
233     Tue Aug 28 23:53:20 MEST 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
234    
235     Fixed truncation race with lock_retrieve() in lock_store().
236     The file has to be truncated only once the exclusive lock is held.
237    
238     Removed spurious debugging messages in .xs file.
239    
240     Sun Jul 1 13:27:32 MEST 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
241    
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.
245    
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
249     from Claudio's code.
250    
251     Made code compile cleanly with -Wall (from Jarkko Hietaniemi).
252    
253     Changed tagnum and classnum from I32 to IV in context. Also
254     from Jarkko.
255    
256     Thu Mar 15 01:22:32 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
257    
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.
262    
263     Sat Feb 17 13:37:37 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
264    
265     Version 1.0.10.
266    
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).
269    
270     Sat Feb 17 13:35:00 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
271    
272     Version 1.0.8, binary format 2.4.
273    
274     Fixed incorrect error message.
275    
276     Now bless objects ASAP at retrieve time, which is meant to fix
277     two bugs:
278    
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
282     recursive retrieval.
283    
284     * Storable hooks asking for serialization of blessed ref could
285     get un-blessed refs at retrieval time, for the very same
286     reason.
287    
288     The fix implemented here was suggested by Nick Ing-Simmons.
289    
290     Added support for blessed ref to tied structures. This is the
291     cause for the binary format change.
292    
293     Added EBCDIC version of the compatibility test with 0.6.11,
294     from Peter Prymmer
295    
296     Added tests for the new features, and to make sure the bugs they
297     are meant to fix are indeed fixed.
298    
299     Wed Jan 3 10:43:18 MET 2001 Raphael Manfredi <Raphael_Manfredi@pobox.com>
300    
301     Removed spurious 'clean' entry in Makefile.PL.
302    
303     Added CAN_FLOCK to determine whether we can flock() or not,
304     by inspecting Perl's configuration parameters, as determined
305     by Configure.
306    
307     Trace offending package when overloading cannot be restored
308     on a scalar.
309    
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
313     definite fix).
314    
315     Sun Nov 5 18:23:48 MET 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
316    
317     Version 1.0.6.
318    
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.
323    
324     Thu Oct 26 19:14:38 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
325    
326     Version 1.0.5.
327    
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.
331    
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.
336    
337     Just check $^O, in t/lock.t: there's no need to pull the whole
338     Config module for that.
339    
340     Mon Oct 23 20:03:49 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
341    
342     Version 1.0.4.
343    
344     Protected calls to flock() for DOS platform: apparently, the
345     flock/fcnlt emulation is reported to be broken on that
346     platform.
347    
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
350     on DOS.
351    
352     Fri Sep 29 21:52:29 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
353    
354     Version 1.0.3.
355    
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!
360    
361     Thu Sep 28 23:46:39 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
362    
363     Version 1.0.2.
364    
365     Fixed spelling in README.
366    
367     Added lock_store, lock_nstore, and lock_retrieve (advisory locking)
368     after a proposal from Erik Haugan <erik@solbors.no>.
369    
370     Perls before 5.004_04 lack newSVpvn, added remapping in XS.
371    
372     Fixed stupid typo in the t/utf8.t test.
373    
374     Sun Sep 17 18:51:10 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
375    
376     Version 1.0.1, binary format 2.3.
377    
378     Documented that doubles are stored stringified by nstore().
379    
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.
384    
385     Now only taint retrieved data when source was tainted. A bug
386     discovered by Marc Lehmann.
387    
388     Added support for UTF-8 strings, a contribution of Marc Lehmann.
389     This is normally only activated in post-5.6 perls.
390    
391     Thu Aug 31 23:06:06 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
392    
393     First official release Storable 1.0, for inclusion in perl 5.7.0.
394     The license scheme is now compatible with Perl's.
395    
396     Thu Aug 24 01:02:02 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
397    
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).
401    
402     Dispatch tables were moved upfront to relieve some compilers,
403     especially on AIX and Windows platforms.
404    
405     Merged 64-bit fixes from perl5-porters.
406    
407     Mon Aug 14 09:22:04 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
408    
409     Added a refcnt dec in retrieve_tied_key(): sv_magic() increases
410     the refcnt on the mg_ptr as well.
411    
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.
415    
416     Sun Aug 13 22:12:59 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
417    
418     Marc Lehmann kindly contributed code to add overloading support
419     and to handle references to tied variables.
420    
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
424     produced by 0.6.
425    
426     Mention new Clone(3) extension in SEE ALSO.
427    
428     Was wrongly optimizing for "undef" values in hashes by not
429     fully recursing: as a result, tied "undef" values were incorrectly
430     serialized.
431    
432     Sun Jul 30 12:59:17 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
433    
434     First revision of Storable 0.7.
435    
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.
439    
440     Changes since 0.6@11:
441    
442     - Moved interface to the "beta" status. Some tiny parts are still
443     subject to change, but nothing important enough to warrant an "alpha"
444     status any longer.
445    
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.
449    
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.
452    
453     - The engine is now fully re-entrant.

455     Sun Apr 2 23:47:50 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
456    
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.
461    
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.
465    
466     Wed Mar 29 19:55:21 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
467    
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).
471    
472     Protect all $@ variables when eval {} used, to avoid corrupting
473     it when store/retrieve is called within an exception handler.
474    
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.
478    
479     Tue May 12 09:15:15 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
480    
481     Fixed shared "undef" bug in hashes, which did not remain shared
482     through store/retrieve.
483    
484     Thu Feb 10 19:48:16 MET 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
485    
486     added last_op_in_netorder() predicate
487     documented last_op_in_netorder()
488     added tests for the new last_op_in_netorder() predicate
489    
490     Wed Oct 20 19:07:36 MEST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
491    
492     Forgot to update VERSION
493    
494     Tue Oct 19 21:25:02 MEST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
495    
496     Added mention of japanese translation for the manual page.
497    
498     Fixed typo in macro that made threaded code not compilable,
499     especially on Win32 platforms.
500    
501     Changed detection of older perls (pre-5.005) by testing PATCHLEVEL
502     directly instead of relying on internal symbols.
503    
504     Tue Sep 14 22:13:28 MEST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
505    
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.
509    
510     Try to avoid compilation warning on 64-bit CPUs. Can't test it,
511     since I don't have access to such machines.
512    
513     Mon Jul 12 14:37:19 METDST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
514    
515     changed my e-mail to pobox.
516    
517     mentionned it is not thread-safe.
518    
519     updated version number.
520    
521     uses new internal PL_* naming convention.
522    
523     Fri Jul 3 13:38:16 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
524    
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.
529    
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.
533    
534     Mon Jun 22 11:00:48 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
535    
536     Changed benchmark figures.
537    
538     Adjust refcnt of tied objects after calling sv_magic() to avoid
539     memory leaks. Contributed by Jeff Gresham.
540    
541     Fri Jun 12 11:50:04 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
542    
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.
546    
547     Now handles Perl immortal scalars explicitely, by storing &sv_yes
548     as such, explicitely.
549    
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.
553    
554     Thu Jun 4 17:21:51 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
555    
556     Baseline for Storable-0.6@0.
557    
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.
561    
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.
565    
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
570     made.
571    
572     Tue May 12 09:15:15 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
573    
574     Version number now got from Storable.pm directly.
575    
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.
579    
580     Thu Apr 30 15:11:30 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
581    
582     Extended the SYNOPSIS section to give quick overview of the
583     routines and their signature.
584    
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.
589    
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
594     share the same one.
595    
596     Tue Jun 3 09:41:33 METDST 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
597    
598     Thanks to a contribution from Benjamin A. Holzman, Storable is now
599     able to correctly serialize tied SVs, i.e. tied arrays, hashes
600     and scalars.
601    
602     Thu Apr 9 18:07:51 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
603    
604     I said SvPOK() had changed to SvPOKp(), but that was a lie...
605    
606     Wed Apr 8 13:14:29 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
607    
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!
611    
612     Wed Mar 25 14:57:02 MET 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
613    
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.
617    
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...
622    
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
626     of portability.
627    
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.
633    
634     Tue Jan 20 09:21:53 MET 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
635    
636     Don't use any '_' in version number.
637    
638     Tue Jan 13 17:51:50 MET 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
639    
640     Updated version number.
641    
642     added binmode() calls for systems where it matters.
643    
644     Be sure to pass globs, not plain file strings, to C routines,
645     so that Storable can be used under the Perl debugger.
646    
647     Wed Nov 5 10:53:22 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
648    
649     Fix memory leaks on seen hash table and returned SV refs.
650    
651     Storable did not work properly when tainting enabled.
652    
653     Fixed "Allocation too large" messages in freeze/thaw and added.
654     proper regression test in t/freeze.t.
655    
656     Tue Jun 3 09:41:33 METDST 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
657    
658     Updated version number
659    
660     Added freeze/thaw interface and dclone.
661    
662     Fri May 16 10:45:47 METDST 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
663    
664     Forgot that AutoLoader does not export its own AUTOLOAD.
665     I could use
666    
667     use AutoLoader 'AUTOLOAD';
668    
669     but that would not be backward compatible. So the export is
670     done by hand...
671    
672     Tue Mar 25 11:21:32 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
673    
674     Empty scalar strings are now "defined" at retrieval time.
675    
676     New test to ensure an empty string is defined when retrieved.
677    
678     Thu Feb 27 16:32:44 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
679    
680     Updated version number
681    
682     Declare VERSION as being used
683    
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)
687    
688     Thu Feb 27 15:58:31 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
689    
690     Updated version number
691    
692     Added VERSION identification
693    
694     Allow build with perl5.003, which is ante perlIO time
695    
696     Mon Jan 13 17:53:18 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
697    
698     Random code fixes.
699    
700     Wed Jan 22 15:19:56 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
701    
702     Updated version number in Makefile.PL.
703    
704     Added "thanks to" section to README.
705    
706     Documented new forgive_me variable.
707    
708     Made 64-bit clean.
709    
710     Added forgive_me support to allow store() of data structures
711     containing non-storable items like CODE refs.
