7 Avoid using "tainted" and "dirty" since Perl remaps them via
8 cpp (i.e. #define). This is deeply harmful when threading
9 is enabled. This concerned both the context structure and
10 local variable and argument names. Brrr..., scary!
12 Thu Sep 28 23:46:39 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
18 Fixed spelling in README.
20 Added lock_store, lock_nstore, and lock_retrieve (advisory locking)
21 after a proposal from Erik Haugan <erik@solbors.no>.
23 Perls before 5.004_04 lack newSVpvn, added remapping in XS.
25 Fixed stupid typo in the t/utf8.t test.
27 Sun Sep 17 18:51:10 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
31 Version 1.0.1, binary format 2.3.
33 Documented that doubles are stored stringified by nstore().
35 Added Salvador Ortiz Garcia in CREDITS section, He identified
36 a bug in the store hooks and proposed the right fix: the class
37 id was allocated too soon. His bug case was also added to
38 the regression test suite.
40 Now only taint retrieved data when source was tainted. A bug
41 discovered by Marc Lehmann.
43 Added support for UTF-8 strings, a contribution of Marc Lehmann.
44 This is normally only activated in post-5.6 perls.
46 Thu Aug 31 23:06:06 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
48 First official release Storable 1.0, for inclusion in perl 5.7.0.
49 The license scheme is now compatible with Perl's.
51 Thu Aug 24 01:02:02 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
56 ANSI-fied most of the code, preparing for Perl core integration.
57 The next version of Storable will be 0.8, and will be integrated
58 into the Perl core (development branch).
60 Dispatch tables were moved upfront to relieve some compilers,
61 especially on AIX and Windows platforms.
63 Merged 64-bit fixes from perl5-porters.
65 Mon Aug 14 09:22:04 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
69 Added a refcnt dec in retrieve_tied_key(): sv_magic() increases
70 the refcnt on the mg_ptr as well.
72 Removed spurious dependency to Devel::Peek, which was used for
73 testing only in t/tied_items.t. Thanks to Conrad Heiney
74 <conrad@fringehead.org> for spotting it first.
76 Sun Aug 13 22:12:59 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
80 Marc Lehmann kindly contributed code to add overloading support
81 and to handle references to tied variables.
83 Rewrote leading blurb about compatibility to make it clearer what
84 "backward compatibility" is about: when I say 0.7 is backward
85 compatible with 0.6, it means the revision 0.7 can read files
88 Mention new Clone(3) extension in SEE ALSO.
90 Was wrongly optimizing for "undef" values in hashes by not
91 fully recursing: as a result, tied "undef" values were incorrectly
94 Sun Jul 30 12:59:17 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
96 First revision of Storable 0.7.
98 The serializing format is new, known as version 2.0. It is fully
99 backward compatible with 0.6. Earlier formats are deprecated and
100 have not even been tested: next version will drop pre-0.6 format.
102 Changes since 0.6@11:
104 - Moved interface to the "beta" status. Some tiny parts are still
105 subject to change, but nothing important enough to warrant an "alpha"
108 - Slightly reduced the size of the Storable image by factorizing
109 object class names and removing final object storage notification due
110 to a redesign of the blessed object storing.
112 - Classes can now redefine how they wish their instances to be serialized
113 and/or deep cloned. Serializing hooks are written in Perl code.
115 - The engine is now fully re-entrant.
117 Sun Apr 2 23:47:50 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
121 Added provision to detect more recent binary formats, since
122 the new upcoming Storable-0.7 will use a different format.
123 In order to prevent attempting the de-serialization of newer
124 formats by older versions, I'm adding this now to the 0.6 series.
126 I'm expecting this revision to be the last of the 0.6 series.
127 Unless it does not work with perl 5.6, which I don't use yet,
128 and therefore against which I cannot test.
130 Wed Mar 29 19:55:21 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
134 Added note about format incompatibilities with old versions
135 (i.e. pre 0.5@9 formats, which cannot be understood as there
136 was no versionning information in the file by then).
138 Protect all $@ variables when eval {} used, to avoid corrupting
139 it when store/retrieve is called within an exception handler.
141 Mistakenly included "patchlevel.h" instead of <patchlevel.h>,
142 preventing Perl's patchlevel from being included, which is
143 needed starting from 5.6.
145 Tue May 12 09:15:15 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
149 Fixed shared "undef" bug in hashes, which did not remain shared
150 through store/retrieve.
152 Thu Feb 10 19:48:16 MET 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com>
156 added last_op_in_netorder() predicate
157 documented last_op_in_netorder()
158 added tests for the new last_op_in_netorder() predicate
160 Wed Oct 20 19:07:36 MEST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
164 Forgot to update VERSION
166 Tue Oct 19 21:25:02 MEST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
170 Added mention of japanese translation for the manual page.
172 Fixed typo in macro that made threaded code not compilable,
173 especially on Win32 platforms.
175 Changed detection of older perls (pre-5.005) by testing PATCHLEVEL
176 directly instead of relying on internal symbols.
178 Tue Sep 14 22:13:28 MEST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
182 Integrated "thread-safe" patch from Murray Nesbitt.
183 Note that this may not be very efficient for threaded code,
184 see comment in the code.
186 Try to avoid compilation warning on 64-bit CPUs. Can't test it,
187 since I don't have access to such machines.
189 Mon Jul 12 14:37:19 METDST 1999 Raphael Manfredi <Raphael_Manfredi@pobox.com>
193 changed my e-mail to pobox.
195 mentionned it is not thread-safe.
197 updated version number.
199 uses new internal PL_* naming convention.
201 Fri Jul 3 13:38:16 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
205 Updated benchmark figures due to recent optimizations done in
206 store(): tagnums are now stored as-is in the hash table, so
207 no surrounding SV is created. And the "shared keys" mode for
208 hash table was turned off.
210 Fixed backward compatibility (wrt 0.5@9) for retrieval of
211 blessed refs. That old version did something wrong, but the
212 bugfix prevented correct retrieval of the old format.
214 Mon Jun 22 11:00:48 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
218 Changed benchmark figures.
220 Adjust refcnt of tied objects after calling sv_magic() to avoid
221 memory leaks. Contributed by Jeff Gresham.
223 Fri Jun 12 11:50:04 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
227 Added workaround for persistent LVALUE-ness in perl5.004. All
228 scalars tagged as being an lvalue are handled as if they were
229 not an lvalue at all. Added test for that LVALUE bug workaround.
231 Now handles Perl immortal scalars explicitely, by storing &sv_yes
232 as such, explicitely.
234 Retrieval of non-immortal undef cannot be shared. Previous
235 version was over-optimizing by not creating a separate SV for
236 all undefined scalars seen.
238 Thu Jun 4 17:21:51 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
242 Baseline for Storable-0.6@0.
244 This version introduces a binary incompatibility in the generated
245 binary image, which is more compact than older ones by approximatively
246 15%, depending on the exact degree of sharing in your structures.
248 The good news is that your older images can still be retrieved with
249 this version, i.e. backward compatibility is preserved. This version
250 of Storable can only generate new binaries however.
252 Another good news is that the retrieval of data structure is
253 significantly quicker than before, because a Perl array is used
254 instead of a hash table to keep track of retrieved objects, and
255 also because the image being smaller, less I/O function calls are
258 Tue May 12 09:15:15 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
262 Version number now got from Storable.pm directly.
264 Fixed overzealous sv_type() optimization, which would make
265 Storable fail when faced with an "upgraded" SV to the PVIV
266 or PVNV kind containing a reference.
268 Thu Apr 30 15:11:30 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
272 Extended the SYNOPSIS section to give quick overview of the
273 routines and their signature.
275 Optimized sv_type() to avoid flags checking when not needed, i.e.
276 when their type makes it impossible for them to be refs or tied.
277 This slightly increases throughput by a few percents when refs
278 and tied variables are marginal occurrences in your data.
280 Stubs for XS now use OutputStream and InputStream file types to
281 make it work when the given file is actually a socket. Perl
282 makes a distinction for sockets in its internal I/O structures
283 by having both a read and a write structure, whereas plain files
286 Tue Jun 3 09:41:33 METDST 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
290 Thanks to a contribution from Benjamin A. Holzman, Storable is now
291 able to correctly serialize tied SVs, i.e. tied arrays, hashes
294 Thu Apr 9 18:07:51 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
298 I said SvPOK() had changed to SvPOKp(), but that was a lie...
300 Wed Apr 8 13:14:29 METDST 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
304 Wrote sizeof(SV *) instead of sizeof(I32) when portable, which
305 in effect mangled the object tags and prevented portability
306 accross 32/64 bit architectures!
308 Wed Mar 25 14:57:02 MET 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
312 Added code example for store_fd() and retrieve_fd() in the
313 man page, to emphasize that file descriptors must be passed as
314 globs, not as plain strings.
316 Cannot use SV addresses as tag when using nstore() on LP64. This
317 was the cause of problems when creating a storable image on an
318 LP64 machine and retrieving it on an ILP32 system, which is
319 exactly what nstore() is meant for...
321 However, we continue to use SV addresses as tags for plain store(),
322 because benchamarking shows that it saves up to 8% of the store
323 time, and store() is meant to be fast at the expense of lack
326 This means there will be approximately an 8% degradation of
327 performance for nstore(), but it's now working as expected.
328 That cost may vary on your machine of course, since it is
329 solely caused by the memory allocation overhead used to create
330 unique SV tags for each distinct stored SV.
332 Tue Jan 20 09:21:53 MET 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
336 Don't use any '_' in version number.
338 Tue Jan 13 17:51:50 MET 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
342 Updated version number.
344 added binmode() calls for systems where it matters.
346 Be sure to pass globs, not plain file strings, to C routines,
347 so that Storable can be used under the Perl debugger.
349 Wed Nov 5 10:53:22 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
353 Fix memory leaks on seen hash table and returned SV refs.
355 Storable did not work properly when tainting enabled.
357 Fixed "Allocation too large" messages in freeze/thaw and added.
358 proper regression test in t/freeze.t.
360 Tue Jun 3 09:41:33 METDST 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
364 Updated version number
366 Added freeze/thaw interface and dclone.
368 Fri May 16 10:45:47 METDST 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
372 Forgot that AutoLoader does not export its own AUTOLOAD.
375 use AutoLoader 'AUTOLOAD';
377 but that would not be backward compatible. So the export is
380 Tue Mar 25 11:21:32 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
384 Empty scalar strings are now "defined" at retrieval time.
386 New test to ensure an empty string is defined when retrieved.
388 Thu Feb 27 16:32:44 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
392 Updated version number
394 Declare VERSION as being used
396 Fixed a typo in the PerlIO_putc remapping.
397 PerlIO_read and perlIO_write inverted size/nb_items.
398 (only relevant for pre-perl5.004 versions)
400 Thu Feb 27 15:58:31 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
404 Updated version number
406 Added VERSION identification
408 Allow build with perl5.003, which is ante perlIO time
410 Mon Jan 13 17:53:18 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
416 Wed Jan 22 15:19:56 MET 1997 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com>
420 Updated version number in Makefile.PL.
422 Added "thanks to" section to README.
424 Documented new forgive_me variable.
428 Added forgive_me support to allow store() of data structures
429 containing non-storable items like CODE refs.
