2 2
3TODO: document conversion algorithm 3 - added support for incremental json parsing (still EXPERIMENTAL).
4 - implemented and added a json_xs command line utility that can convert
5 from/to a number of serialisation formats - tell me if you need more.
6 - moved down =encoding directive a bit, too much breaks if its the first
7 pod directive :/.
8 - removed documentation section on other modules, it became somewhat
9 outdated and is nowadays mostly of historical interest.
4 10
50.3 112.1 Wed Mar 19 23:23:18 CET 2008
12 - update documentation here and there: add a large section
13 about utf8/latin1/ascii flags, add a security consideration
14 and extend and clarify the JSON and YAML section.
15 - medium speed enhancements when encoding/decoding non-ascii chars.
16 - minor speedup in number encoding case.
17 - extend and clarify the section on incompatibilities
18 between YAML and JSON.
19 - switch to static inline from just inline when using gcc.
20 - add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
21 - fix some issues with UV to JSON conversion of unknown impact.
22 - published the yahoo locals search result used in benchmarks as the
23 original url changes so comparison is impossible.
24
252.01 Wed Dec 5 11:40:28 CET 2007
26 - INCOMPATIBLE API CHANGE: to_json and from_json have been
27 renamed to encode_json/decode_json for JSON.pm compatibility.
28 The old functions croak and might be replaced by JSON.pm
29 comaptible versions in some later release.
30
312.0 Tue Dec 4 11:30:46 CET 2007
32 - this is supposed to be the first version of JSON::XS
33 compatible with version 2.0+ of the JSON module.
34 Using the JSON module as frontend to JSON::XS should be
35 as fast as using JSON::XS directly, so consider using it
36 instead.
37 - added get_* methods for all "simple" options.
38 - make JSON::XS subclassable.
39
401.53 Tue Nov 13 23:58:33 CET 2007
41 - minor doc clarifications.
42 - fixed many doc typos (patch by Thomas L. Shinnick).
43
441.52 Mon Oct 15 03:22:06 CEST 2007
45 - remove =encoding pod directive again, it confuses too many pod
46 parsers :/.
47
481.51 Sat Oct 13 03:55:56 CEST 2007
49 - encode empty arrays/hashes in a compact way when pretty is enabled.
50 - apparently JSON::XS was used to find some bugs in the
51 JSON_checker testsuite, so add (the corrected) JSON_checker tests to
52 the testsuite.
53 - quite a bit of doc updates/extension.
54 - require 5.8.2, as this seems to be the first unicode-stable version.
55
561.5 Tue Aug 28 04:05:38 CEST 2007
57 - add support for tied hashes, based on ideas and testcase by
58 Marcus Holland-Moritz.
59 - implemented relaxed parsing mode where some extensions are being
60 accepted. generation is still JSON-only.
61
621.44 Wed Aug 22 01:02:44 CEST 2007
63 - very experimental process-emulation support, slowing everything down.
64 the horribly broken perl threads are still not supported - YMMV.
65
661.43 Thu Jul 26 13:26:37 CEST 2007
67 - convert big json numbers exclusively consisting of digits to NV
68 only when there is no loss of precision, otherwise to string.
69
701.42 Tue Jul 24 00:51:18 CEST 2007
71 - fix a crash caused by not handling missing array elements
72 (report and testcase by Jay Kuri).
73
741.41 Tue Jul 10 18:21:44 CEST 2007
75 - fix compilation with NDEBUG (assert side-effect),
76 affects convert_blessed only.
77 - fix a bug in decode filters calling ENTER; SAVETMPS;
78 one time too often.
79 - catch a typical error in TO_JSON methods.
80 - antique-ised XS.xs again to work with outdated
81 C compilers (windows...).
82
831.4 Mon Jul 2 10:06:30 CEST 2007
84 - add convert_blessed setting.
85 - encode did not catch all blessed objects, encoding their
86 contents in most cases. This has been fixed by introducing
87 the allow_blessed setting.
88 - added filter_json_object and filter_json_single_key_object
89 settings that specify a callback to be called when
90 all/specific json objects are encountered.
91 - assume that most object keys are simple ascii words and
92 optimise this case, penalising the general case. This can
93 speed up decoding by 30% in typical cases and gives
94 a smaller and faster perl hash.
95 - implemented simpleminded, optional resource size checking
96 in decode_json.
97 - remove objToJson/jsonToObj aliases, as the next version
98 of JSON will not have them either.
99 - bit the bullet and converted the very simple json object
100 into a more complex one.
101 - work around a bug where perl wrongly claims an integer
102 is not an integer.
103 - unbundle JSON::XS::Boolean into own pm file so Storable
104 and similar modules can resolve the overloading when thawing.
105
1061.3 Sun Jun 24 01:55:02 CEST 2007
107 - make JSON::XS::true and false special overloaded objects
108 and return those instead of 1 and 0 for those json atoms
109 (JSON::PP compatibility is NOT achieved yet).
110 - add JSON::XS::is_bool predicate to test for those special
111 values.
112 - add a reference to
113 http://jpsykes.com/47/practical-csrf-and-json-security.
114 - removed require 5.8.8 again, it is just not very expert-friendly.
115 Also try to be more compatible with slightly older versions,
116 which are not recommended (because they are buggy).
117
1181.24 Mon Jun 11 05:40:49 CEST 2007
119 - added informative section on JSON-as-YAML.
120 - get rid of some c99-isms again.
121 - localise dec->cur in decode_str, speeding up
122 string decoding considerably (>15% on my amd64 + gcc).
123 - increased SHORT_STRING_LEN to 16kb: stack space is
124 usually plenty, and this actually saves memory
125 when !shrinking as short strings will fit perfectly.
126
1271.23 Wed Jun 6 20:13:06 CEST 2007
128 - greatly improved small integer encoding and decoding speed.
129 - implement a number of µ-optimisations.
130 - updated benchmarks.
131
1321.22 Thu May 24 00:07:25 CEST 2007
133 - require 5.8.8 explicitly as older perls do not seem to offer
134 the required macros.
135 - possibly made it compile on so-called C compilers by microsoft.
136
1371.21 Wed May 9 18:40:32 CEST 2007
138 - character offset reported for trailing garbage was random.
139
1401.2 Wed May 9 18:35:01 CEST 2007
141 - decode did not work with magical scalars (doh!).
142 - added latin1 flag to produce JSON texts in the latin1 subset
143 of unicode.
144 - flag trailing garbage as error.
145 - new decode_prefix method that returns the number
146 of characters consumed by a decode.
147 - max octets/char in perls UTF-X is actually 13, not 11,
148 as pointed out by Glenn Linderman.
149 - fixed typoe reported by YAMASHINA Hio.
150
1511.11 Mon Apr 9 07:05:49 CEST 2007
152 - properly 0-terminate sv's returned by encode to help
153 C libraries that expect that 0 to be there.
154 - partially "port" JSON from C to microsofts fucking broken
155 pseudo-C. They should be burned to the ground for pissing
156 on standards. And I should be stoned for even trying to
157 support this filthy excuse for a c compiler.
158
1591.1 Wed Apr 4 01:45:00 CEST 2007
160 - clarify documentation (pointed out by Quinn Weaver).
161 - decode_utf8 sometimes did not correctly flag errors,
162 leading to segfaults.
163 - further reduced default nesting depth to 512 due to the test
164 failure by that anonymous "chris" whose e-mail address seems
165 to be impossible to get. Tests on other freebsd systems indicate
166 that this is likely a problem in his/her configuration and not this
167 module.
168 - renamed json => JSON in error messages.
169 - corrected the character offset in some error messages.
170
1711.01 Sat Mar 31 16:15:40 CEST 2007
172 - do not segfault when from_json/decode gets passed
173 a non-string object (reported by Florian Ragwitz).
174 This has no effect on normal operation.
175
1761.0 Thu Mar 29 04:43:34 CEST 2007
177 - the long awaited (by me) 1.0 version.
178 - add \0 (JSON::XS::false) and \1 (JSON::XS::true) mappings to JSON
179 true and false.
180 - add some more notes to shrink, as suggested by Alex Efros.
181 - improve testsuite.
182 - halve the default nesting depth limit, to hopefully make it
183 work on Freebsd (unfortunately, the cpan tester did not
184 send me his report, so I cannot ask about the stack limit on fbsd).
185
1860.8 Mon Mar 26 00:10:48 CEST 2007
187 - fix a memleak when decoding hashes.
188 - export jsonToBj and objToJson as aliases
189 to to_json and from_json, to reduce incompatibilities
190 between JSON/JSON::PC and JSON::XS. (experimental).
191 - implement a maximum nesting depth for both en- and de-coding.
192 - added a security considerations sections.
193
1940.7 Sun Mar 25 01:46:30 CET 2007
195 - code cleanup.
196 - fix a memory overflow bug when indenting.
197 - pretty-printing now up to 15% faster.
198 - improve decoding speed of strings by
199 up to 50% by specialcasing short strings.
200 - further decoding speedups for strings using
201 lots of \u escapes.
202 - improve utf8 decoding speed for U+80 .. U+7FF.
203
2040.5 Sat Mar 24 20:41:51 CET 2007
205 - added the UTF-16 encoding example hinted at in previous
206 versions.
207 - minor documentation fixes.
208 - fix a bug in and optimise canonicalising fastpath
209 (reported by Craig Manley).
210 - remove a subtest that breaks with bleadperl (reported
211 by Andreas König).
212
2130.31 Sat Mar 24 02:14:34 CET 2007
214 - documentation updates.
215 - do some casting to hopefully fix Andreas' problem.
216 - nuke bogus json rpc stuff.
217

237 - croak when encoding to ascii and an out-of-range
238 (non-unicode) codepoint is encountered.
