4 | |
5 | |
6 | ANSI-fied most of the code, preparing for Perl core integration. |
7 | The next version of Storable will be 0.8, and will be integrated |
8 | into the Perl core (development branch). |
9 | |
10 | Dispatch tables were moved upfront to relieve some compilers, |
11 | especially on AIX and Windows platforms. |
12 | |
13 | Merged 64-bit fixes from perl5-porters. |

17 | . Description: |
18 | |
19 | Added a refcnt dec in retrieve_tied_key(): sv_magic() increases |
20 | the refcnt on the mg_ptr as well. |
21 | |
22 | Removed spurious dependency to Devel::Peek, which was used for |
23 | testing only in t/tied_items.t. Thanks to Conrad Heiney |
24 | <conrad@fringehead.org> for spotting it first. |

28 | . Description: |
29 | |
30 | Marc Lehmann kindly contributed code to add overloading support |
31 | and to handle references to tied variables. |
32 | |
33 | Rewrote leading blurb about compatibility to make it clearer what |
34 | "backward compatibility" is about: when I say 0.7 is backward |
35 | compatible with 0.6, it means the revision 0.7 can read files |
36 | produced by 0.6. |
37 | |
38 | Mention new Clone(3) extension in SEE ALSO. |
39 | |
40 | Was wrongly optimizing for "undef" values in hashes by not |
41 | fully recursing: as a result, tied "undef" values were incorrectly |
42 | serialized. |

45 | |
46 | First revision of Storable 0.7. |
47 | |
48 | The serializing format is new, known as version 2.0. It is fully |
49 | backward compatible with 0.6. Earlier formats are deprecated and |
50 | have not even been tested: next version will drop pre-0.6 format. |
51 | |
52 | Changes since 0.6@11: |
53 | |
54 | - Moved interface to the "beta" status. Some tiny parts are still |
55 | subject to change, but nothing important enough to warrant an "alpha" |
56 | status any longer. |
57 | |
58 | - Slightly reduced the size of the Storable image by factorizing |
59 | object class names and removing final object storage notification due |
60 | to a redesign of the blessed object storing. |
61 | |
62 | - Classes can now redefine how they wish their instances to be serialized |
63 | and/or deep cloned. Serializing hooks are written in Perl code. |
64 | |
65 | - The engine is now fully re-entrant. |

68 | |
69 | . Description: |
70 | |
71 | Added provision to detect more recent binary formats, since |
72 | the new upcoming Storable-0.7 will use a different format. |
73 | In order to prevent attempting the de-serialization of newer |
74 | formats by older versions, I'm adding this now to the 0.6 series. |
75 | |
76 | I'm expecting this revision to be the last of the 0.6 series. |
77 | Unless it does not work with perl 5.6, which I don't use yet, |
78 | and therefore against which I cannot test. |

81 | |
82 | . Description: |
83 | |
84 | Added note about format incompatibilities with old versions |
85 | (i.e. pre 0.5@9 formats, which cannot be understood as there |
86 | was no versionning information in the file by then). |
87 | |
88 | Protect all $@ variables when eval {} used, to avoid corrupting |
89 | it when store/retrieve is called within an exception handler. |
90 | |
91 | Mistakenly included "patchlevel.h" instead of <patchlevel.h>, |
92 | preventing Perl's patchlevel from being included, which is |
93 | needed starting from 5.6. |

122 | Fixed typo in macro that made threaded code not compilable, |
123 | especially on Win32 platforms. |
124 | |
125 | Changed detection of older perls (pre-5.005) by testing PATCHLEVEL |
126 | directly instead of relying on internal symbols. |

153 | . Description: |
154 | |
155 | Updated benchmark figures due to recent optimizations done in |
156 | store(): tagnums are now stored as-is in the hash table, so |
157 | no surrounding SV is created. And the "shared keys" mode for |
158 | hash table was turned off. |
159 | |
160 | Fixed backward compatibility (wrt 0.5@9) for retrieval of |
161 | blessed refs. That old version did something wrong, but the |
162 | bugfix prevented correct retrieval of the old format. |

174 | |
175 | . Description: |
176 | |
177 | Added workaround for persistent LVALUE-ness in perl5.004. All |
178 | scalars tagged as being an lvalue are handled as if they were |
179 | not an lvalue at all. Added test for that LVALUE bug workaround. |
180 | |
181 | Now handles Perl immortal scalars explicitely, by storing &sv_yes |
182 | as such, explicitely. |
183 | |
184 | Retrieval of non-immortal undef cannot be shared. Previous |
185 | version was over-optimizing by not creating a separate SV for |
186 | all undefined scalars seen. |

189 | |
190 | . Description: |
191 | |
192 | Baseline for Storable-0.6@0. |
193 | |
194 | This version introduces a binary incompatibility in the generated |
195 | binary image, which is more compact than older ones by approximatively |
196 | 15%, depending on the exact degree of sharing in your structures. |
197 | |
198 | The good news is that your older images can still be retrieved with |
199 | this version, i.e. backward compatibility is preserved. This version |
200 | of Storable can only generate new binaries however. |
201 | |
202 | Another good news is that the retrieval of data structure is |
203 | significantly quicker than before, because a Perl array is used |
204 | instead of a hash table to keep track of retrieved objects, and |
205 | also because the image being smaller, less I/O function calls are |
206 | made. |

210 | . Description: |
211 | |
212 | Version number now got from Storable.pm directly. |
213 | |
214 | Fixed overzealous sv_type() optimization, which would make |
215 | Storable fail when faced with an "upgraded" SV to the PVIV |
216 | or PVNV kind containing a reference. |

220 | . Description: |
221 | |
222 | Extended the SYNOPSIS section to give quick overview of the |
223 | routines and their signature. |
224 | |
225 | Optimized sv_type() to avoid flags checking when not needed, i.e. |
226 | when their type makes it impossible for them to be refs or tied. |
227 | This slightly increases throughput by a few percents when refs |
228 | and tied variables are marginal occurrences in your data. |
229 | |
230 | Stubs for XS now use OutputStream and InputStream file types to |
231 | make it work when the given file is actually a socket. Perl |
232 | makes a distinction for sockets in its internal I/O structures |
233 | by having both a read and a write structure, whereas plain files |
234 | share the same one. |

238 | . Description: |
239 | |
240 | Thanks to a contribution from Benjamin A. Holzman, Storable is now |
241 | able to correctly serialize tied SVs, i.e. tied arrays, hashes |
242 | and scalars. |

252 | . Description: |
253 | |
254 | Wrote sizeof(SV *) instead of sizeof(I32) when portable, which |
255 | in effect mangled the object tags and prevented portability |
256 | accross 32/64 bit architectures! |
257 | |
258 | Wed Mar 25 14:57:02 MET 1998 Raphael Manfredi <Raphael_Manfredi@grenoble.hp.com> |
259 | |
260 | . Description: |
261 | |
262 | Added code example for store_fd() and retrieve_fd() in the |
263 | man page, to emphasize that file descriptors must be passed as |
264 | globs, not as plain strings. |
265 | |
266 | Cannot use SV addresses as tag when using nstore() on LP64. This |
267 | was the cause of problems when creating a storable image on an |
268 | LP64 machine and retrieving it on an ILP32 system, which is |
269 | exactly what nstore() is meant for... |
270 | |
271 | However, we continue to use SV addresses as tags for plain store(), |
272 | because benchamarking shows that it saves up to 8% of the store |
273 | time, and store() is meant to be fast at the expense of lack |
274 | of portability. |
275 | |
276 | This means there will be approximately an 8% degradation of |
277 | performance for nstore(), but it's now working as expected. |
278 | That cost may vary on your machine of course, since it is |
279 | solely caused by the memory allocation overhead used to create |
280 | unique SV tags for each distinct stored SV. |
