3TODO: maybe use some overload magic to decode true and false into something 32.27
4 not 0 or 1 in perl. or use attached magic? 4 - support relaxed option inside the incremental parser
5 (testcase provided by Makamaka).
5 6
72.26 Sat Oct 10 03:26:19 CEST 2009
8 - big integers could become truncated (based on patch
9 by Strobl Anton).
10 - output format change: indent now adds a final newline, which is
11 more expected and more true to the documentation.
12
132.25 Sat Aug 8 12:04:41 CEST 2009
14 - the perl debugger completely breaks lvalue subs - try to work
15 around the issue.
16 - ignore RMAGICAL hashes w.r.t. CANONICAL.
17 - try to work around a possible char signedness issue on aix.
18 - require common sense.
19
202.24 Sat May 30 08:25:45 CEST 2009
21 - the incremental parser did not update its parse offset
22 pointer correctly when parsing utf8-strings (nicely
23 debugged by Martin Evans).
24 - appending a non-utf8-string to the incremental parser
25 in utf8 mode failed to upgrade the string.
26 - wording of parse error messages has been improved.
27
282.232 Sun Feb 22 11:12:25 CET 2009
29 - use an exponential algorithm to extend strings, to
30 help platforms with bad or abysmal==windows memory
31 allocater performance, at the expense of some memory
32 wastage (use shrink to recover this extra memory).
33 (nicely analysed by Dmitry Karasik).
34
352.2311 Thu Feb 19 02:12:54 CET 2009
36 - add a section "JSON and ECMAscript" to explain some
37 incompatibilities between the two (problem was noted by
38 various people).
39 - add t/20_faihu.t.
40
412.231 Thu Nov 20 04:59:08 CET 2008
42 - work around 5.10.0 magic bugs where manipulating magic values
43 (such as $1) would permanently damage them as perl would
44 ignore the magicalness, by making a full copy of the string,
45 reported by Dmitry Karasik.
46 - work around spurious warnings under older perl 5.8's.
47
482.23 Mon Sep 29 05:08:29 CEST 2008
49 - fix a compilation problem when perl is not using char * as, well,
50 char *.
51 - use PL_hexdigit in favour of rolling our own.
52
532.2222 Sun Jul 20 18:49:00 CEST 2008
54 - same game again, broken 5.10 finds yet another assertion
55 failure, and the workaround causes additional runtime warnings.
56 Work around the next assertion AND the warning. 5.10 seriously
57 needs to adjust it's attitude against working code.
58
592.222 Sat Jul 19 06:15:34 CEST 2008
60 - you work around one -DDEBUGGING assertion bug in perl 5.10
61 just to hit the next one. work around this one, too.
62
632.22 Tue Jul 15 13:26:51 CEST 2008
64 - allow higher nesting levels in incremental parser.
65 - error out earlier in some cases in the incremental parser
66 (as suggested by Yuval Kogman).
67 - improve incr-parser test (Yuval Kogman).
68
692.21 Tue Jun 3 08:43:23 CEST 2008
70 - (hopefully) work around a perl 5.10 bug with -DDEBUGGING.
71 - remove the experimental status of the incremental parser interface.
72 - move =encoding around again, to avoid bugs with search.cpan.org.
73 when can we finally have utf-8 in pod???
74 - add ->incr_reset method.
75
762.2 Wed Apr 16 20:37:25 CEST 2008
77 - lifted the log2 rounding restriction of max_depth and max_size.
78 - make booleans mutable by creating a copy instead of handing out
79 the same scalar (reported by pasha sadri).
80 - added support for incremental json parsing (still EXPERIMENTAL).
81 - implemented and added a json_xs command line utility that can convert
82 from/to a number of serialisation formats - tell me if you need more.
83 - implement allow_unknown/get_allow_unknown methods.
84 - fixed documentation of max_depth w.r.t. higher and equal.
85 - moved down =encoding directive a bit, too much breaks if it's the first
86 pod directive :/.
87 - removed documentation section on other modules, it became somewhat
88 outdated and is nowadays mostly of historical interest.
89
902.1 Wed Mar 19 23:23:18 CET 2008
91 - update documentation here and there: add a large section
92 about utf8/latin1/ascii flags, add a security consideration
93 and extend and clarify the JSON and YAML section.
94 - medium speed enhancements when encoding/decoding non-ascii chars.
95 - minor speedup in number encoding case.
96 - extend and clarify the section on incompatibilities
97 between YAML and JSON.
98 - switch to static inline from just inline when using gcc.
99 - add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
100 - fix some issues with UV to JSON conversion of unknown impact.
101 - published the yahoo locals search result used in benchmarks as the
102 original url changes so comparison is impossible.
103
1042.01 Wed Dec 5 11:40:28 CET 2007
105 - INCOMPATIBLE API CHANGE: to_json and from_json have been
106 renamed to encode_json/decode_json for JSON.pm compatibility.
107 The old functions croak and might be replaced by JSON.pm
108 comaptible versions in some later release.
109
1102.0 Tue Dec 4 11:30:46 CET 2007
111 - this is supposed to be the first version of JSON::XS
112 compatible with version 2.0+ of the JSON module.
113 Using the JSON module as frontend to JSON::XS should be
114 as fast as using JSON::XS directly, so consider using it
115 instead.
116 - added get_* methods for all "simple" options.
117 - make JSON::XS subclassable.
118
1191.53 Tue Nov 13 23:58:33 CET 2007
120 - minor doc clarifications.
121 - fixed many doc typos (patch by Thomas L. Shinnick).
122
1231.52 Mon Oct 15 03:22:06 CEST 2007
124 - remove =encoding pod directive again, it confuses too many pod
125 parsers :/.
126
1271.51 Sat Oct 13 03:55:56 CEST 2007
128 - encode empty arrays/hashes in a compact way when pretty is enabled.
129 - apparently JSON::XS was used to find some bugs in the
130 JSON_checker testsuite, so add (the corrected) JSON_checker tests to
131 the testsuite.
132 - quite a bit of doc updates/extension.
133 - require 5.8.2, as this seems to be the first unicode-stable version.
134
1351.5 Tue Aug 28 04:05:38 CEST 2007
136 - add support for tied hashes, based on ideas and testcase by
137 Marcus Holland-Moritz.
138 - implemented relaxed parsing mode where some extensions are being
139 accepted. generation is still JSON-only.
140
1411.44 Wed Aug 22 01:02:44 CEST 2007
142 - very experimental process-emulation support, slowing everything down.
143 the horribly broken perl threads are still not supported - YMMV.
144
1451.43 Thu Jul 26 13:26:37 CEST 2007
146 - convert big json numbers exclusively consisting of digits to NV
147 only when there is no loss of precision, otherwise to string.
148
1491.42 Tue Jul 24 00:51:18 CEST 2007
150 - fix a crash caused by not handling missing array elements
151 (report and testcase by Jay Kuri).
152
1531.41 Tue Jul 10 18:21:44 CEST 2007
154 - fix compilation with NDEBUG (assert side-effect),
155 affects convert_blessed only.
156 - fix a bug in decode filters calling ENTER; SAVETMPS;
157 one time too often.
158 - catch a typical error in TO_JSON methods.
159 - antique-ised XS.xs again to work with outdated
160 C compilers (windows...).
161
1621.4 Mon Jul 2 10:06:30 CEST 2007
163 - add convert_blessed setting.
164 - encode did not catch all blessed objects, encoding their
165 contents in most cases. This has been fixed by introducing
166 the allow_blessed setting.
167 - added filter_json_object and filter_json_single_key_object
168 settings that specify a callback to be called when
169 all/specific json objects are encountered.
170 - assume that most object keys are simple ascii words and
171 optimise this case, penalising the general case. This can
172 speed up decoding by 30% in typical cases and gives
173 a smaller and faster perl hash.
174 - implemented simpleminded, optional resource size checking
175 in decode_json.
176 - remove objToJson/jsonToObj aliases, as the next version
177 of JSON will not have them either.
178 - bit the bullet and converted the very simple json object
179 into a more complex one.
180 - work around a bug where perl wrongly claims an integer
181 is not an integer.
182 - unbundle JSON::XS::Boolean into own pm file so Storable
183 and similar modules can resolve the overloading when thawing.
184
1851.3 Sun Jun 24 01:55:02 CEST 2007
186 - make JSON::XS::true and false special overloaded objects
187 and return those instead of 1 and 0 for those json atoms
188 (JSON::PP compatibility is NOT achieved yet).
189 - add JSON::XS::is_bool predicate to test for those special
190 values.
191 - add a reference to
192 http://jpsykes.com/47/practical-csrf-and-json-security.
193 - removed require 5.8.8 again, it is just not very expert-friendly.
194 Also try to be more compatible with slightly older versions,
195 which are not recommended (because they are buggy).
196
1971.24 Mon Jun 11 05:40:49 CEST 2007
198 - added informative section on JSON-as-YAML.
199 - get rid of some c99-isms again.
200 - localise dec->cur in decode_str, speeding up
201 string decoding considerably (>15% on my amd64 + gcc).
202 - increased SHORT_STRING_LEN to 16kb: stack space is
203 usually plenty, and this actually saves memory
204 when !shrinking as short strings will fit perfectly.
205
2061.23 Wed Jun 6 20:13:06 CEST 2007
207 - greatly improved small integer encoding and decoding speed.
208 - implement a number of ยต-optimisations.
209 - updated benchmarks.
