72.34 Thu May 23 11:30:34 CEST 2013
8 - work around bugs in perl 5.18 breaking more than 100
9 widely used modules, without a fix in sight because
10 p5pers don't care about CPAN anymore.
11 - when canonicalising, only allocate up to 64 hash key
12 pointers on the stack. for larger hashes, use the heap,
13 to avoid using too much stackspace.
14 - discuss the problem with setlocale (reported by a few victims).
15
162.33 Wed Aug 1 21:03:52 CEST 2012
17 - internal encode/decode XS wrappers did not expect stack
18 moves caused by callbacks (analyzed and testcase by Jesse Luehrs).
19 - add bencode as to/from option in bin/json_xs.
20 - add -e option to json_xs, and none and string in/out formats.
21
222.32 Thu Aug 11 19:06:38 CEST 2011
23 - fix a bug in the initial whitespace accumulation.
24
252.31 Wed Jul 27 17:53:05 CEST 2011
26 - don't accumulate initial whitespace in the incremental buffer
27 (this can be useful to allow whitespace-keepalive on a tcp
28 connection without triggering the max_size limit).
29 - properly croak on some invalid inputs that are not strings
30 (e.g. undef) when trying to decode a json text (reported
31 and analyzed by Goro Fuji).
32
332.3 Wed Aug 18 01:26:47 CEST 2010
34 - make sure decoder doesn't change the decoding in the incremental
35 parser (testcase provided by Hendrik Schumacher).
36 - applied patch by DaTa for Data::Dumper support in json_xs.
37 - added -t dump support to json_xs, using Data::Dump.
38 - added -f eval support to json_xs.
39
402.29 Wed Mar 17 02:39:12 CET 2010
41 - fix a memory leak when callbacks set using filter_json_object
42 or filter_json_single_key_object were called (great testcase
43 by Eric Wilhelm).
44
452.28 Thu Mar 11 20:30:46 CET 2010
46 - implement our own atof function - perl's can be orders of
47 magnitudes slower than even the system one. on the positive
48 side, ours seems to be more exact in general than perl's.
49 (testcase provided by Tim Meadowcroft).
50 - clarify floating point conversion issues a bit.
51 - update jpsykes csrf article url.
52 - updated benchmark section - JSON::PP became much faster!
53
542.27 Thu Jan 7 07:35:08 CET 2010
55 - support relaxed option inside the incremental parser
56 (testcase provided by IKEGAMI via Makamaka).
57
582.26 Sat Oct 10 03:26:19 CEST 2009
59 - big integers could become truncated (based on patch
60 by Strobl Anton).
61 - output format change: indent now adds a final newline, which is
62 more expected and more true to the documentation.
63
642.25 Sat Aug 8 12:04:41 CEST 2009
65 - the perl debugger completely breaks lvalue subs - try to work
66 around the issue.
67 - ignore RMAGICAL hashes w.r.t. CANONICAL.
68 - try to work around a possible char signedness issue on aix.
69 - require common sense.
70
712.24 Sat May 30 08:25:45 CEST 2009
72 - the incremental parser did not update its parse offset
73 pointer correctly when parsing utf8-strings (nicely
74 debugged by Martin Evans).
75 - appending a non-utf8-string to the incremental parser
76 in utf8 mode failed to upgrade the string.
77 - wording of parse error messages has been improved.
78
792.232 Sun Feb 22 11:12:25 CET 2009
80 - use an exponential algorithm to extend strings, to
81 help platforms with bad or abysmal==windows memory
82 allocater performance, at the expense of some memory
83 wastage (use shrink to recover this extra memory).
84 (nicely analysed by Dmitry Karasik).
85
862.2311 Thu Feb 19 02:12:54 CET 2009
87 - add a section "JSON and ECMAscript" to explain some
88 incompatibilities between the two (problem was noted by
89 various people).
90 - add t/20_faihu.t.
91
922.231 Thu Nov 20 04:59:08 CET 2008
93 - work around 5.10.0 magic bugs where manipulating magic values
94 (such as $1) would permanently damage them as perl would
95 ignore the magicalness, by making a full copy of the string,
96 reported by Dmitry Karasik.
97 - work around spurious warnings under older perl 5.8's.
98
992.23 Mon Sep 29 05:08:29 CEST 2008
100 - fix a compilation problem when perl is not using char * as, well,
101 char *.
102 - use PL_hexdigit in favour of rolling our own.
103
1042.2222 Sun Jul 20 18:49:00 CEST 2008
105 - same game again, broken 5.10 finds yet another assertion
106 failure, and the workaround causes additional runtime warnings.
107 Work around the next assertion AND the warning. 5.10 seriously
108 needs to adjust it's attitude against working code.
109
1102.222 Sat Jul 19 06:15:34 CEST 2008
111 - you work around one -DDEBUGGING assertion bug in perl 5.10
112 just to hit the next one. work around this one, too.
113
1142.22 Tue Jul 15 13:26:51 CEST 2008
115 - allow higher nesting levels in incremental parser.
116 - error out earlier in some cases in the incremental parser
117 (as suggested by Yuval Kogman).
118 - improve incr-parser test (Yuval Kogman).
119
1202.21 Tue Jun 3 08:43:23 CEST 2008
121 - (hopefully) work around a perl 5.10 bug with -DDEBUGGING.
122 - remove the experimental status of the incremental parser interface.
123 - move =encoding around again, to avoid bugs with search.cpan.org.
124 when can we finally have utf-8 in pod???
125 - add ->incr_reset method.
126
1272.2 Wed Apr 16 20:37:25 CEST 2008
128 - lifted the log2 rounding restriction of max_depth and max_size.
129 - make booleans mutable by creating a copy instead of handing out
130 the same scalar (reported by pasha sadri).
131 - added support for incremental json parsing (still EXPERIMENTAL).
132 - implemented and added a json_xs command line utility that can convert
133 from/to a number of serialisation formats - tell me if you need more.
134 - implement allow_unknown/get_allow_unknown methods.
135 - fixed documentation of max_depth w.r.t. higher and equal.
136 - moved down =encoding directive a bit, too much breaks if it's the first
137 pod directive :/.
138 - removed documentation section on other modules, it became somewhat
139 outdated and is nowadays mostly of historical interest.
140
1412.1 Wed Mar 19 23:23:18 CET 2008
142 - update documentation here and there: add a large section
143 about utf8/latin1/ascii flags, add a security consideration
144 and extend and clarify the JSON and YAML section.
145 - medium speed enhancements when encoding/decoding non-ascii chars.
146 - minor speedup in number encoding case.
147 - extend and clarify the section on incompatibilities
148 between YAML and JSON.
149 - switch to static inline from just inline when using gcc.
150 - add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
151 - fix some issues with UV to JSON conversion of unknown impact.
152 - published the yahoo locals search result used in benchmarks as the
153 original url changes so comparison is impossible.
154
1552.01 Wed Dec 5 11:40:28 CET 2007
156 - INCOMPATIBLE API CHANGE: to_json and from_json have been
157 renamed to encode_json/decode_json for JSON.pm compatibility.
158 The old functions croak and might be replaced by JSON.pm
159 comaptible versions in some later release.
160
1612.0 Tue Dec 4 11:30:46 CET 2007
162 - this is supposed to be the first version of JSON::XS
163 compatible with version 2.0+ of the JSON module.
164 Using the JSON module as frontend to JSON::XS should be
165 as fast as using JSON::XS directly, so consider using it
166 instead.
167 - added get_* methods for all "simple" options.
168 - make JSON::XS subclassable.
169
1701.53 Tue Nov 13 23:58:33 CET 2007
171 - minor doc clarifications.
172 - fixed many doc typos (patch by Thomas L. Shinnick).
173
1741.52 Mon Oct 15 03:22:06 CEST 2007
175 - remove =encoding pod directive again, it confuses too many pod
176 parsers :/.
177
1781.51 Sat Oct 13 03:55:56 CEST 2007
179 - encode empty arrays/hashes in a compact way when pretty is enabled.
180 - apparently JSON::XS was used to find some bugs in the
181 JSON_checker testsuite, so add (the corrected) JSON_checker tests to
182 the testsuite.
183 - quite a bit of doc updates/extension.
184 - require 5.8.2, as this seems to be the first unicode-stable version.
185
1861.5 Tue Aug 28 04:05:38 CEST 2007
187 - add support for tied hashes, based on ideas and testcase by
188 Marcus Holland-Moritz.
189 - implemented relaxed parsing mode where some extensions are being
190 accepted. generation is still JSON-only.
191
1921.44 Wed Aug 22 01:02:44 CEST 2007
193 - very experimental process-emulation support, slowing everything down.
194 the horribly broken perl threads are still not supported - YMMV.
195
1961.43 Thu Jul 26 13:26:37 CEST 2007
197 - convert big json numbers exclusively consisting of digits to NV
198 only when there is no loss of precision, otherwise to string.
199
2001.42 Tue Jul 24 00:51:18 CEST 2007
201 - fix a crash caused by not handling missing array elements
202 (report and testcase by Jay Kuri).
203
2041.41 Tue Jul 10 18:21:44 CEST 2007
205 - fix compilation with NDEBUG (assert side-effect),
206 affects convert_blessed only.
207 - fix a bug in decode filters calling ENTER; SAVETMPS;
208 one time too often.
209 - catch a typical error in TO_JSON methods.
210 - antique-ised XS.xs again to work with outdated
211 C compilers (windows...).
212
2131.4 Mon Jul 2 10:06:30 CEST 2007
5 - add convert_blessed option. 214 - add convert_blessed setting.
6 - encode did not catch all blessed objects, encoding their 215 - encode did not catch all blessed objects, encoding their
7 contents in most cases. This has been fixed by introducing 216 contents in most cases. This has been fixed by introducing
8 the allow_blessed setting. 217 the allow_blessed setting.
218 - added filter_json_object and filter_json_single_key_object
219 settings that specify a callback to be called when
220 all/specific json objects are encountered.
9 - assume that most object keys are simple ascii words and 221 - assume that most object keys are simple ascii words and
10 optimise this case, penalising the general case. This can 222 optimise this case, penalising the general case. This can
11 speed up decoding by 30% in typical cases and gives 223 speed up decoding by 30% in typical cases and gives
12 a smaller and faster perl hash. 224 a smaller and faster perl hash.
13 - implemented simpleminded, optional resource size checking 225 - implemented simpleminded, optional resource size checking
14 in decode_json. 226 in decode_json.
227 - remove objToJson/jsonToObj aliases, as the next version
228 of JSON will not have them either.
229 - bit the bullet and converted the very simple json object
230 into a more complex one.
231 - work around a bug where perl wrongly claims an integer
232 is not an integer.
233 - unbundle JSON::XS::Boolean into own pm file so Storable
234 and similar modules can resolve the overloading when thawing.
