10
11 - fix a bug introduced by a perl bug workaround that would cause
12 incremental parsing with a sv_chop panic.
13 - json_xs: toformat failure error message fixed.
14 - json_xs: allow cyclic data structures in CBOR.
15
163.02 Fri Feb 26 22:45:20 CET 2016
17 - allow_nonref now affects booleans (\1, $Types::Serialiser::Boolean)
18 as well (reported by Alex Efros).
19 - allow literal tabs in strings in relaxed mode (patch by
20 lubo.rintel@gooddata.com).
21 - support "cbor" format in json_xs tool.
22 - support (and fix) calling encode and decode in list context
23 (reported by Вадим Власов).
24 - work around a bug in older perls crashing when presented
25 with shared hash keys (Reini Urban).
26 - use stability canary.
27
283.01 Tue Oct 29 16:55:15 CET 2013
29 - backport to perls < 5.18 (reported by Paul Howarth).
30
313.0 Tue Oct 29 01:35:37 CET 2013
32 - implemented an object tagging extension (using the
33 Types::Serialiser serialisation protocol).
34 - reworked the documentation regarding object serialisation,
35 add a new OBJECT SERIALISATION section that explains th
36 whole process.
37 - new setting: allow_tags.
38 - switch to Types::Serialiser booleans.
39 - remove to_json/from_json.
40 - other minor improvements to the documentation.
41
422.34 Thu May 23 11:30:34 CEST 2013
43 - work around bugs in perl 5.18 breaking more than 100
44 widely used modules, without a fix in sight because
45 p5pers don't care about CPAN anymore.
46 - when canonicalising, only allocate up to 64 hash key
47 pointers on the stack. for larger hashes, use the heap,
48 to avoid using too much stackspace.
49 - discuss the problem with setlocale (reported by a few victims).
50
512.33 Wed Aug 1 21:03:52 CEST 2012
52 - internal encode/decode XS wrappers did not expect stack
53 moves caused by callbacks (analyzed and testcase by Jesse Luehrs).
54 - add bencode as to/from option in bin/json_xs.
55 - add -e option to json_xs, and none and string in/out formats.
56
572.32 Thu Aug 11 19:06:38 CEST 2011
58 - fix a bug in the initial whitespace accumulation.
59
602.31 Wed Jul 27 17:53:05 CEST 2011
61 - don't accumulate initial whitespace in the incremental buffer
62 (this can be useful to allow whitespace-keepalive on a tcp
63 connection without triggering the max_size limit).
64 - properly croak on some invalid inputs that are not strings
65 (e.g. undef) when trying to decode a json text (reported
66 and analyzed by Goro Fuji).
67
682.3 Wed Aug 18 01:26:47 CEST 2010
69 - make sure decoder doesn't change the decoding in the incremental
70 parser (testcase provided by Hendrik Schumacher).
71 - applied patch by DaTa for Data::Dumper support in json_xs.
72 - added -t dump support to json_xs, using Data::Dump.
73 - added -f eval support to json_xs.
74
752.29 Wed Mar 17 02:39:12 CET 2010
76 - fix a memory leak when callbacks set using filter_json_object
77 or filter_json_single_key_object were called (great testcase
78 by Eric Wilhelm).
79
802.28 Thu Mar 11 20:30:46 CET 2010
81 - implement our own atof function - perl's can be orders of
82 magnitudes slower than even the system one. on the positive
83 side, ours seems to be more exact in general than perl's.
84 (testcase provided by Tim Meadowcroft).
85 - clarify floating point conversion issues a bit.
86 - update jpsykes csrf article url.
87 - updated benchmark section - JSON::PP became much faster!
88
892.27 Thu Jan 7 07:35:08 CET 2010
90 - support relaxed option inside the incremental parser
91 (testcase provided by IKEGAMI via Makamaka).
92
932.26 Sat Oct 10 03:26:19 CEST 2009
94 - big integers could become truncated (based on patch
95 by Strobl Anton).
96 - output format change: indent now adds a final newline, which is
97 more expected and more true to the documentation.
98
992.25 Sat Aug 8 12:04:41 CEST 2009
100 - the perl debugger completely breaks lvalue subs - try to work
101 around the issue.
102 - ignore RMAGICAL hashes w.r.t. CANONICAL.
103 - try to work around a possible char signedness issue on aix.
104 - require common sense.
105
1062.24 Sat May 30 08:25:45 CEST 2009
107 - the incremental parser did not update its parse offset
108 pointer correctly when parsing utf8-strings (nicely
109 debugged by Martin Evans).
110 - appending a non-utf8-string to the incremental parser
111 in utf8 mode failed to upgrade the string.
112 - wording of parse error messages has been improved.
113
1142.232 Sun Feb 22 11:12:25 CET 2009
115 - use an exponential algorithm to extend strings, to
116 help platforms with bad or abysmal==windows memory
117 allocater performance, at the expense of some memory
118 wastage (use shrink to recover this extra memory).
119 (nicely analysed by Dmitry Karasik).
120
1212.2311 Thu Feb 19 02:12:54 CET 2009
122 - add a section "JSON and ECMAscript" to explain some
123 incompatibilities between the two (problem was noted by
124 various people).
125 - add t/20_faihu.t.
126
1272.231 Thu Nov 20 04:59:08 CET 2008
128 - work around 5.10.0 magic bugs where manipulating magic values
129 (such as $1) would permanently damage them as perl would
130 ignore the magicalness, by making a full copy of the string,
131 reported by Dmitry Karasik.
132 - work around spurious warnings under older perl 5.8's.
133
1342.23 Mon Sep 29 05:08:29 CEST 2008
135 - fix a compilation problem when perl is not using char * as, well,
136 char *.
137 - use PL_hexdigit in favour of rolling our own.
138
1392.2222 Sun Jul 20 18:49:00 CEST 2008
140 - same game again, broken 5.10 finds yet another assertion
141 failure, and the workaround causes additional runtime warnings.
142 Work around the next assertion AND the warning. 5.10 seriously
143 needs to adjust it's attitude against working code.
144
1452.222 Sat Jul 19 06:15:34 CEST 2008
146 - you work around one -DDEBUGGING assertion bug in perl 5.10
147 just to hit the next one. work around this one, too.
148
1492.22 Tue Jul 15 13:26:51 CEST 2008
150 - allow higher nesting levels in incremental parser.
151 - error out earlier in some cases in the incremental parser
152 (as suggested by Yuval Kogman).
153 - improve incr-parser test (Yuval Kogman).
154
1552.21 Tue Jun 3 08:43:23 CEST 2008
156 - (hopefully) work around a perl 5.10 bug with -DDEBUGGING.
157 - remove the experimental status of the incremental parser interface.
158 - move =encoding around again, to avoid bugs with search.cpan.org.
159 when can we finally have utf-8 in pod???
160 - add ->incr_reset method.
161
1622.2 Wed Apr 16 20:37:25 CEST 2008
163 - lifted the log2 rounding restriction of max_depth and max_size.
164 - make booleans mutable by creating a copy instead of handing out
165 the same scalar (reported by pasha sadri).
166 - added support for incremental json parsing (still EXPERIMENTAL).
167 - implemented and added a json_xs command line utility that can convert
168 from/to a number of serialisation formats - tell me if you need more.
169 - implement allow_unknown/get_allow_unknown methods.
170 - fixed documentation of max_depth w.r.t. higher and equal.
171 - moved down =encoding directive a bit, too much breaks if it's the first
172 pod directive :/.
173 - removed documentation section on other modules, it became somewhat
174 outdated and is nowadays mostly of historical interest.
175
1762.1 Wed Mar 19 23:23:18 CET 2008
177 - update documentation here and there: add a large section
178 about utf8/latin1/ascii flags, add a security consideration
179 and extend and clarify the JSON and YAML section.
180 - medium speed enhancements when encoding/decoding non-ascii chars.
181 - minor speedup in number encoding case.
182 - extend and clarify the section on incompatibilities
183 between YAML and JSON.
184 - switch to static inline from just inline when using gcc.
185 - add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
186 - fix some issues with UV to JSON conversion of unknown impact.
187 - published the yahoo locals search result used in benchmarks as the
188 original url changes so comparison is impossible.
189
1902.01 Wed Dec 5 11:40:28 CET 2007
191 - INCOMPATIBLE API CHANGE: to_json and from_json have been
192 renamed to encode_json/decode_json for JSON.pm compatibility.
193 The old functions croak and might be replaced by JSON.pm
194 comaptible versions in some later release.
195
1962.0 Tue Dec 4 11:30:46 CET 2007
197 - this is supposed to be the first version of JSON::XS
198 compatible with version 2.0+ of the JSON module.
199 Using the JSON module as frontend to JSON::XS should be
200 as fast as using JSON::XS directly, so consider using it
201 instead.
202 - added get_* methods for all "simple" options.
203 - make JSON::XS subclassable.
204
2051.53 Tue Nov 13 23:58:33 CET 2007
206 - minor doc clarifications.
207 - fixed many doc typos (patch by Thomas L. Shinnick).
208
2091.52 Mon Oct 15 03:22:06 CEST 2007
210 - remove =encoding pod directive again, it confuses too many pod
211 parsers :/.
212
2131.51 Sat Oct 13 03:55:56 CEST 2007
214 - encode empty arrays/hashes in a compact way when pretty is enabled.
215 - apparently JSON::XS was used to find some bugs in the
216 JSON_checker testsuite, so add (the corrected) JSON_checker tests to
217 the testsuite.
218 - quite a bit of doc updates/extension.
219 - require 5.8.2, as this seems to be the first unicode-stable version.
220
2211.5 Tue Aug 28 04:05:38 CEST 2007
222 - add support for tied hashes, based on ideas and testcase by
223 Marcus Holland-Moritz.
224 - implemented relaxed parsing mode where some extensions are being
225 accepted. generation is still JSON-only.
226
2271.44 Wed Aug 22 01:02:44 CEST 2007
228 - very experimental process-emulation support, slowing everything down.
229 the horribly broken perl threads are still not supported - YMMV.
230
2311.43 Thu Jul 26 13:26:37 CEST 2007
232 - convert big json numbers exclusively consisting of digits to NV
233 only when there is no loss of precision, otherwise to string.
234
2351.42 Tue Jul 24 00:51:18 CEST 2007
236 - fix a crash caused by not handling missing array elements
237 (report and testcase by Jay Kuri).
238
2391.41 Tue Jul 10 18:21:44 CEST 2007
240 - fix compilation with NDEBUG (assert side-effect),
241 affects convert_blessed only.
242 - fix a bug in decode filters calling ENTER; SAVETMPS;
243 one time too often.
244 - catch a typical error in TO_JSON methods.
245 - antique-ised XS.xs again to work with outdated
246 C compilers (windows...).
247
2481.4 Mon Jul 2 10:06:30 CEST 2007
6 - add convert_blessed option. 249 - add convert_blessed setting.
7 - encode did not catch all blessed objects, encoding their 250 - encode did not catch all blessed objects, encoding their
8 contents in most cases. This has been fixed by introducing 251 contents in most cases. This has been fixed by introducing
9 the allow_blessed setting. 252 the allow_blessed setting.
253 - added filter_json_object and filter_json_single_key_object
254 settings that specify a callback to be called when
255 all/specific json objects are encountered.
10 - assume that most object keys are simple ascii words and 256 - assume that most object keys are simple ascii words and
11 optimise this case, penalising the general case. This can 257 optimise this case, penalising the general case. This can
12 speed up decoding by 30% in typical cases and gives 258 speed up decoding by 30% in typical cases and gives
13 a smaller and faster perl hash. 259 a smaller and faster perl hash.
14 - implemented simpleminded, optional resource size checking 260 - implemented simpleminded, optional resource size checking
15 in decode_json. 261 in decode_json.
16 - remove objToJson/jsonToObj aliases, as the next version 262 - remove objToJson/jsonToObj aliases, as the next version
17 of JSON will not have them either. 263 of JSON will not have them either.
18 - bit the bullet and converted the very simple json object 264 - bit the bullet and converted the very simple json object
19 into a more complex one. 265 into a more complex one.
266 - work around a bug where perl wrongly claims an integer
267 is not an integer.
268 - unbundle JSON::XS::Boolean into own pm file so Storable
269 and similar modules can resolve the overloading when thawing.
20 270
211.3 Sun Jun 24 01:55:02 CEST 2007 2711.3 Sun Jun 24 01:55:02 CEST 2007
22 - make JSON::XS::true and false special overloaded objects 272 - make JSON::XS::true and false special overloaded objects
23 and return those instead of 1 and 0 for those json atoms 273 and return those instead of 1 and 0 for those json atoms
24 (JSON::PP compatibility is NOT achieved yet). 274 (JSON::PP compatibility is NOT achieved yet).
