9 | |
10 | |
11 | ANSI-fied most of the code, preparing for Perl core integration. |
12 | The next version of Storable will be 0.8, and will be integrated |
13 | into the Perl core (development branch). |
14 | |
15 | Dispatch tables were moved upfront to relieve some compilers, |
16 | especially on AIX and Windows platforms. |
17 | |
18 | Merged 64-bit fixes from perl5-porters. |

22 | . Description: |
23 | |
24 | Added a refcnt dec in retrieve_tied_key(): sv_magic() increases |
25 | the refcnt on the mg_ptr as well. |
26 | |
27 | Removed spurious dependency to Devel::Peek, which was used for |
28 | testing only in t/tied_items.t. Thanks to Conrad Heiney |
29 | <conrad@fringehead.org> for spotting it first. |

33 | . Description: |
34 | |
35 | Marc Lehmann kindly contributed code to add overloading support |
36 | and to handle references to tied variables. |
37 | |
38 | Rewrote leading blurb about compatibility to make it clearer what |
39 | "backward compatibility" is about: when I say 0.7 is backward |
40 | compatible with 0.6, it means the revision 0.7 can read files |
41 | produced by 0.6. |
42 | |
43 | Mention new Clone(3) extension in SEE ALSO. |
44 | |
45 | Was wrongly optimizing for "undef" values in hashes by not |
46 | fully recursing: as a result, tied "undef" values were incorrectly |
47 | serialized. |

50 | |
51 | First revision of Storable 0.7. |
52 | |
53 | The serializing format is new, known as version 2.0. It is fully |
54 | backward compatible with 0.6. Earlier formats are deprecated and |
55 | have not even been tested: next version will drop pre-0.6 format. |
56 | |
57 | Changes since 0.6@11: |
58 | |
59 | - Moved interface to the "beta" status. Some tiny parts are still |
60 | subject to change, but nothing important enough to warrant an "alpha" |
61 | status any longer. |
62 | |
63 | - Slightly reduced the size of the Storable image by factorizing |
64 | object class names and removing final object storage notification due |
65 | to a redesign of the blessed object storing. |
66 | |
67 | - Classes can now redefine how they wish their instances to be serialized |
68 | and/or deep cloned. Serializing hooks are written in Perl code. |
69 | |
70 | - The engine is now fully re-entrant. |

74 | . Description: |
75 | |
76 | Added provision to detect more recent binary formats, since |
77 | the new upcoming Storable-0.7 will use a different format. |
78 | In order to prevent attempting the de-serialization of newer |
79 | formats by older versions, I'm adding this now to the 0.6 series. |
80 | |
81 | I'm expecting this revision to be the last of the 0.6 series. |
82 | Unless it does not work with perl 5.6, which I don't use yet, |
83 | and therefore against which I cannot test. |

87 | . Description: |
88 | |
89 | Added note about format incompatibilities with old versions |
90 | (i.e. pre 0.5@9 formats, which cannot be understood as there |
91 | was no versionning information in the file by then). |
92 | |
93 | Protect all $@ variables when eval {} used, to avoid corrupting |
94 | it when store/retrieve is called within an exception handler. |
95 | |
96 | Mistakenly included "patchlevel.h" instead of <patchlevel.h>, |
97 | preventing Perl's patchlevel from being included, which is |
98 | needed starting from 5.6. |

158 | . Description: |
159 | |
160 | Updated benchmark figures due to recent optimizations done in |
161 | store(): tagnums are now stored as-is in the hash table, so |
162 | no surrounding SV is created. And the "shared keys" mode for |
163 | hash table was turned off. |
164 | |
165 | Fixed backward compatibility (wrt 0.5@9) for retrieval of |
166 | blessed refs. That old version did something wrong, but the |
167 | bugfix prevented correct retrieval of the old format. |

179 | |
180 | . Description: |
181 | |
182 | Added workaround for persistent LVALUE-ness in perl5.004. All |
183 | scalars tagged as being an lvalue are handled as if they were |
184 | not an lvalue at all. Added test for that LVALUE bug workaround. |
185 | |
186 | Now handles Perl immortal scalars explicitely, by storing &sv_yes |
187 | as such, explicitely. |
188 | |
189 | Retrieval of non-immortal undef cannot be shared. Previous |
190 | version was over-optimizing by not creating a separate SV for |
191 | all undefined scalars seen. |

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

215 | . Description: |
216 | |
217 | Version number now got from Storable.pm directly. |
218 | |
219 | Fixed overzealous sv_type() optimization, which would make |
220 | Storable fail when faced with an "upgraded" SV to the PVIV |
221 | or PVNV kind containing a reference. |

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

244 | |
245 | Thanks to a contribution from Benjamin A. Holzman, Storable is now |
246 | able to correctly serialize tied SVs, i.e. tied arrays, hashes |
247 | and scalars. |

257 | . Description: |
258 | |
259 | Wrote sizeof(SV *) instead of sizeof(I32) when portable, which |
260 | in effect mangled the object tags and prevented portability |
261 | accross 32/64 bit architectures! |
262 | |

264 | |
265 | . Description: |
266 | |
267 | Added code example for store_fd() and retrieve_fd() in the |
268 | man page, to emphasize that file descriptors must be passed as |
269 | globs, not as plain strings. |
270 | |
271 | Cannot use SV addresses as tag when using nstore() on LP64. This |
272 | was the cause of problems when creating a storable image on an |
273 | LP64 machine and retrieving it on an ILP32 system, which is |
274 | exactly what nstore() is meant for... |
275 | |
276 | However, we continue to use SV addresses as tags for plain store(), |
277 | because benchamarking shows that it saves up to 8% of the store |
278 | time, and store() is meant to be fast at the expense of lack |
279 | of portability. |
280 | |
281 | This means there will be approximately an 8% degradation of |
282 | performance for nstore(), but it's now working as expected. |
283 | That cost may vary on your machine of course, since it is |
284 | solely caused by the memory allocation overhead used to create |
285 | unique SV tags for each distinct stored SV. |
