4 | |
5 | Version 1.0.5. |
6 | |
7 | Documented that store() and retrieve() can return undef. |
8 | That is, the error reporting is not always made via exceptions, |
9 | as the paragraph on error reporting was implying. |
10 | |
11 | Auto requires module of blessed ref when STORABLE_thaw misses. |
12 | When the Storable engine looks for the STORABLE_thaw hook and |
13 | does not find it, it now tries to require the package into which |
14 | the blessed reference is. |
15 | |
16 | Just check $^O, in t/lock.t: there's no need to pull the whole |
17 | Config module for that. |

23 | Version 1.0.3. |
24 | |
25 | Avoid using "tainted" and "dirty" since Perl remaps them via |
26 | cpp (i.e. #define). This is deeply harmful when threading |
27 | is enabled. This concerned both the context structure and |
28 | local variable and argument names. Brrr..., scary! |

33 | |
34 | Version 1.0.2. |
35 | |
36 | Fixed spelling in README. |
37 | |
38 | Added lock_store, lock_nstore, and lock_retrieve (advisory locking) |
39 | after a proposal from Erik Haugan <erik@solbors.no>. |
40 | |
41 | Perls before 5.004_04 lack newSVpvn, added remapping in XS. |
42 | |
43 | Fixed stupid typo in the t/utf8.t test. |

47 | . Description: |
48 | |
49 | Version 1.0.1, binary format 2.3. |
50 | |
51 | Documented that doubles are stored stringified by nstore(). |
52 | |
53 | Added Salvador Ortiz Garcia in CREDITS section, He identified |
54 | a bug in the store hooks and proposed the right fix: the class |
55 | id was allocated too soon. His bug case was also added to |
56 | the regression test suite. |
57 | |
58 | Now only taint retrieved data when source was tainted. A bug |
59 | discovered by Marc Lehmann. |
60 | |
61 | Added support for UTF-8 strings, a contribution of Marc Lehmann. |
62 | This is normally only activated in post-5.6 perls. |

72 | |
73 | |
74 | ANSI-fied most of the code, preparing for Perl core integration. |
75 | The next version of Storable will be 0.8, and will be integrated |
76 | into the Perl core (development branch). |
77 | |
78 | Dispatch tables were moved upfront to relieve some compilers, |
79 | especially on AIX and Windows platforms. |
80 | |
81 | Merged 64-bit fixes from perl5-porters. |

86 | |
87 | Added a refcnt dec in retrieve_tied_key(): sv_magic() increases |
88 | the refcnt on the mg_ptr as well. |
89 | |
90 | Removed spurious dependency to Devel::Peek, which was used for |
91 | testing only in t/tied_items.t. Thanks to Conrad Heiney |

96 | . Description: |
97 | |
98 | Marc Lehmann kindly contributed code to add overloading support |
99 | and to handle references to tied variables. |
100 | |
101 | Rewrote leading blurb about compatibility to make it clearer what |
102 | "backward compatibility" is about: when I say 0.7 is backward |
103 | compatible with 0.6, it means the revision 0.7 can read files |
104 | produced by 0.6. |
105 | |
106 | Mention new Clone(3) extension in SEE ALSO. |
107 | |
108 | Was wrongly optimizing for "undef" values in hashes by not |
109 | fully recursing: as a result, tied "undef" values were incorrectly |
110 | serialized. |
111 | |
112 | Sun Jul 30 12:59:17 MEST 2000 Raphael Manfredi <Raphael_Manfredi@pobox.com> |
113 | |
114 | First revision of Storable 0.7. |
115 | |
116 | The serializing format is new, known as version 2.0. It is fully |
117 | backward compatible with 0.6. Earlier formats are deprecated and |
118 | have not even been tested: next version will drop pre-0.6 format. |
119 | |
120 | Changes since 0.6@11: |
121 | |
122 | - Moved interface to the "beta" status. Some tiny parts are still |
123 | subject to change, but nothing important enough to warrant an "alpha" |
124 | status any longer. |
125 | |
126 | - Slightly reduced the size of the Storable image by factorizing |
127 | object class names and removing final object storage notification due |
128 | to a redesign of the blessed object storing. |
129 | |
130 | - Classes can now redefine how they wish their instances to be serialized |
131 | and/or deep cloned. Serializing hooks are written in Perl code. |
132 | |
133 | - The engine is now fully re-entrant. |

137 | . Description: |
138 | |
139 | Added provision to detect more recent binary formats, since |
140 | the new upcoming Storable-0.7 will use a different format. |
141 | In order to prevent attempting the de-serialization of newer |
142 | formats by older versions, I'm adding this now to the 0.6 series. |
143 | |
144 | I'm expecting this revision to be the last of the 0.6 series. |
145 | Unless it does not work with perl 5.6, which I don't use yet, |
146 | and therefore against which I cannot test. |

149 | |
150 | . Description: |
151 | |
152 | Added note about format incompatibilities with old versions |
153 | (i.e. pre 0.5@9 formats, which cannot be understood as there |
154 | was no versionning information in the file by then). |
155 | |
156 | Protect all $@ variables when eval {} used, to avoid corrupting |
157 | it when store/retrieve is called within an exception handler. |
158 | |
159 | Mistakenly included "patchlevel.h" instead of <patchlevel.h>, |
160 | preventing Perl's patchlevel from being included, which is |
161 | needed starting from 5.6. |

191 | especially on Win32 platforms. |

221 | . Description: |
222 | |
223 | Updated benchmark figures due to recent optimizations done in |
224 | store(): tagnums are now stored as-is in the hash table, so |
225 | no surrounding SV is created. And the "shared keys" mode for |
226 | hash table was turned off. |
227 | |
228 | Fixed backward compatibility (wrt 0.5@9) for retrieval of |
229 | blessed refs. That old version did something wrong, but the |
230 | bugfix prevented correct retrieval of the old format. |

243 | . Description: |
244 | |
245 | Added workaround for persistent LVALUE-ness in perl5.004. All |
246 | scalars tagged as being an lvalue are handled as if they were |
247 | not an lvalue at all. Added test for that LVALUE bug workaround. |
248 | |
249 | Now handles Perl immortal scalars explicitely, by storing &sv_yes |
250 | as such, explicitely. |
251 | |
252 | Retrieval of non-immortal undef cannot be shared. Previous |
253 | version was over-optimizing by not creating a separate SV for |
254 | all undefined scalars seen. |

257 | |
258 | . Description: |
259 | |
260 | Baseline for Storable-0.6@0. |
261 | |
262 | This version introduces a binary incompatibility in the generated |
263 | binary image, which is more compact than older ones by approximatively |
264 | 15%, depending on the exact degree of sharing in your structures. |
265 | |
266 | The good news is that your older images can still be retrieved with |
267 | this version, i.e. backward compatibility is preserved. This version |
268 | of Storable can only generate new binaries however. |
269 | |
270 | Another good news is that the retrieval of data structure is |
271 | significantly quicker than before, because a Perl array is used |
272 | instead of a hash table to keep track of retrieved objects, and |
273 | also because the image being smaller, less I/O function calls are |
274 | made. |

278 | . Description: |
279 | |
280 | Version number now got from Storable.pm directly. |
281 | |
282 | Fixed overzealous sv_type() optimization, which would make |
283 | Storable fail when faced with an "upgraded" SV to the PVIV |
284 | or PVNV kind containing a reference. |
285 | |

288 | . Description: |
289 | |
290 | Extended the SYNOPSIS section to give quick overview of the |
291 | routines and their signature. |
292 | |
293 | Optimized sv_type() to avoid flags checking when not needed, i.e. |
294 | when their type makes it impossible for them to be refs or tied. |
295 | This slightly increases throughput by a few percents when refs |
296 | and tied variables are marginal occurrences in your data. |
297 | |
298 | Stubs for XS now use OutputStream and InputStream file types to |
299 | make it work when the given file is actually a socket. Perl |
300 | makes a distinction for sockets in its internal I/O structures |
301 | by having both a read and a write structure, whereas plain files |
302 | share the same one. |

307 | |
308 | Thanks to a contribution from Benjamin A. Holzman, Storable is now |

310 | and scalars. |

320 | . Description: |
321 | |
322 | Wrote sizeof(SV *) instead of sizeof(I32) when portable, which |
323 | in effect mangled the object tags and prevented portability |
324 | accross 32/64 bit architectures! |
325 | |
326 | Wed Mar 25 14:57:02 MET 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com> |
327 | |
328 | . Description: |
329 | |
330 | Added code example for store_fd() and retrieve_fd() in the |
331 | man page, to emphasize that file descriptors must be passed as |
332 | globs, not as plain strings. |
333 | |
334 | Cannot use SV addresses as tag when using nstore() on LP64. This |
335 | was the cause of problems when creating a storable image on an |
336 | LP64 machine and retrieving it on an ILP32 system, which is |
337 | exactly what nstore() is meant for... |
338 | |
339 | However, we continue to use SV addresses as tags for plain store(), |
340 | because benchamarking shows that it saves up to 8% of the store |
341 | time, and store() is meant to be fast at the expense of lack |
342 | of portability. |
343 | |
344 | This means there will be approximately an 8% degradation of |
345 | performance for nstore(), but it's now working as expected. |
346 | That cost may vary on your machine of course, since it is |
347 | solely caused by the memory allocation overhead used to create |
348 | unique SV tags for each distinct stored SV. |
