| 5 | Added a refcnt dec in retrieve_tied_key(): sv_magic() increases |
| 6 | the refcnt on the mg_ptr as well. |
| 7 | |
| 8 | Removed spurious dependency to Devel::Peek, which was used for |
| 9 | testing only in t/tied_items.t. Thanks to Conrad Heiney |
| 10 | <conrad@fringehead.org> for spotting it first. |

| 14 | . Description: |
| 15 | |
| 16 | Marc Lehmann kindly contributed code to add overloading support |
| 17 | and to handle references to tied variables. |
| 18 | |
| 19 | Rewrote leading blurb about compatibility to make it clearer what |
| 20 | "backward compatibility" is about: when I say 0.7 is backward |
| 21 | compatible with 0.6, it means the revision 0.7 can read files |
| 22 | produced by 0.6. |
| 23 | |
| 24 | Mention new Clone(3) extension in SEE ALSO. |
| 25 | |
| 26 | Was wrongly optimizing for "undef" values in hashes by not |
| 27 | fully recursing: as a result, tied "undef" values were incorrectly |
| 28 | serialized. |

| 31 | |
| 32 | First revision of Storable 0.7. |
| 33 | |
| 34 | The serializing format is new, known as version 2.0. It is fully |
| 35 | backward compatible with 0.6. Earlier formats are deprecated and |
| 36 | have not even been tested: next version will drop pre-0.6 format. |
| 37 | |
| 38 | Changes since 0.6@11: |
| 39 | |
| 40 | - Moved interface to the "beta" status. Some tiny parts are still |
| 41 | subject to change, but nothing important enough to warrant an "alpha" |
| 42 | status any longer. |
| 43 | |
| 44 | - Slightly reduced the size of the Storable image by factorizing |
| 45 | object class names and removing final object storage notification due |
| 46 | to a redesign of the blessed object storing. |
| 47 | |
| 48 | - Classes can now redefine how they wish their instances to be serialized |
| 49 | and/or deep cloned. Serializing hooks are written in Perl code. |
| 50 | |
| 51 | - The engine is now fully re-entrant. |

| 55 | . Description: |
| 56 | |
| 57 | Added provision to detect more recent binary formats, since |
| 58 | the new upcoming Storable-0.7 will use a different format. |
| 59 | In order to prevent attempting the de-serialization of newer |
| 60 | formats by older versions, I'm adding this now to the 0.6 series. |
| 61 | |
| 62 | I'm expecting this revision to be the last of the 0.6 series. |
| 63 | Unless it does not work with perl 5.6, which I don't use yet, |
| 64 | and therefore against which I cannot test. |

| 68 | . Description: |
| 69 | |
| 70 | Added note about format incompatibilities with old versions |
| 71 | (i.e. pre 0.5@9 formats, which cannot be understood as there |
| 72 | was no versionning information in the file by then). |
| 73 | |
| 74 | Protect all $@ variables when eval {} used, to avoid corrupting |
| 75 | it when store/retrieve is called within an exception handler. |
| 76 | |
| 77 | Mistakenly included "patchlevel.h" instead of <patchlevel.h>, |
| 78 | preventing Perl's patchlevel from being included, which is |
| 79 | needed starting from 5.6. |

| 106 | Added mention of japanese translation for the manual page. |
| 107 | |
| 108 | Fixed typo in macro that made threaded code not compilable, |
| 109 | especially on Win32 platforms. |
| 110 | |
| 111 | Changed detection of older perls (pre-5.005) by testing PATCHLEVEL |
| 112 | directly instead of relying on internal symbols. |

| 139 | . Description: |
| 140 | |
| 141 | Updated benchmark figures due to recent optimizations done in |
| 142 | store(): tagnums are now stored as-is in the hash table, so |
| 143 | no surrounding SV is created. And the "shared keys" mode for |
| 144 | hash table was turned off. |
| 145 | |
| 146 | Fixed backward compatibility (wrt 0.5@9) for retrieval of |
| 147 | blessed refs. That old version did something wrong, but the |
| 148 | bugfix prevented correct retrieval of the old format. |

| 161 | . Description: |
| 162 | |
| 163 | Added workaround for persistent LVALUE-ness in perl5.004. All |
| 164 | scalars tagged as being an lvalue are handled as if they were |
| 165 | not an lvalue at all. Added test for that LVALUE bug workaround. |
| 166 | |
| 167 | Now handles Perl immortal scalars explicitely, by storing &sv_yes |
| 168 | as such, explicitely. |
| 169 | |
| 170 | Retrieval of non-immortal undef cannot be shared. Previous |
| 171 | version was over-optimizing by not creating a separate SV for |
| 172 | all undefined scalars seen. |
| 173 | |

| 176 | . Description: |
| 177 | |
| 178 | Baseline for Storable-0.6@0. |
| 179 | |
| 180 | This version introduces a binary incompatibility in the generated |
| 181 | binary image, which is more compact than older ones by approximatively |
| 182 | 15%, depending on the exact degree of sharing in your structures. |
| 183 | |
| 184 | The good news is that your older images can still be retrieved with |
| 185 | this version, i.e. backward compatibility is preserved. This version |
| 186 | of Storable can only generate new binaries however. |
| 187 | |
| 188 | Another good news is that the retrieval of data structure is |
| 189 | significantly quicker than before, because a Perl array is used |
| 190 | instead of a hash table to keep track of retrieved objects, and |
| 191 | also because the image being smaller, less I/O function calls are |
| 192 | made. |

| 198 | Version number now got from Storable.pm directly. |
| 199 | |
| 200 | Fixed overzealous sv_type() optimization, which would make |
| 201 | Storable fail when faced with an "upgraded" SV to the PVIV |
| 202 | or PVNV kind containing a reference. |

| 206 | . Description: |
| 207 | |
| 208 | Extended the SYNOPSIS section to give quick overview of the |
| 209 | routines and their signature. |
| 210 | |
| 211 | Optimized sv_type() to avoid flags checking when not needed, i.e. |
| 212 | when their type makes it impossible for them to be refs or tied. |
| 213 | This slightly increases throughput by a few percents when refs |
| 214 | and tied variables are marginal occurrences in your data. |
| 215 | |
| 216 | Stubs for XS now use OutputStream and InputStream file types to |
| 217 | make it work when the given file is actually a socket. Perl |
| 218 | makes a distinction for sockets in its internal I/O structures |
| 219 | by having both a read and a write structure, whereas plain files |
| 220 | share the same one. |

| 224 | . Description: |
| 225 | |
| 226 | Thanks to a contribution from Benjamin A. Holzman, Storable is now |
| 227 | able to correctly serialize tied SVs, i.e. tied arrays, hashes |
| 228 | and scalars. |

| 238 | . Description: |
| 239 | |
| 240 | Wrote sizeof(SV *) instead of sizeof(I32) when portable, which |
| 241 | in effect mangled the object tags and prevented portability |
| 242 | accross 32/64 bit architectures! |
| 243 | |

| 245 | |
| 246 | . Description: |
| 247 | |
| 248 | Added code example for store_fd() and retrieve_fd() in the |
| 249 | man page, to emphasize that file descriptors must be passed as |
| 250 | globs, not as plain strings. |
| 251 | |
| 252 | Cannot use SV addresses as tag when using nstore() on LP64. This |
| 253 | was the cause of problems when creating a storable image on an |
| 254 | LP64 machine and retrieving it on an ILP32 system, which is |
| 255 | exactly what nstore() is meant for... |
| 256 | |
| 257 | However, we continue to use SV addresses as tags for plain store(), |
| 258 | because benchamarking shows that it saves up to 8% of the store |
| 259 | time, and store() is meant to be fast at the expense of lack |
| 260 | of portability. |
| 261 | |
| 262 | This means there will be approximately an 8% degradation of |
| 263 | performance for nstore(), but it's now working as expected. |
| 264 | That cost may vary on your machine of course, since it is |
| 265 | solely caused by the memory allocation overhead used to create |
| 266 | unique SV tags for each distinct stored SV. |
