2 2
3TODO: document conversion algorithm 3 - implemented and added a json_xs command line utility that can convert
4 from/to a number of serialisation formats - tell me if you need more.
5 - moved down =encoding directive a bit, too much breaks if its the first
6 pod directive :/.
4 7
50.3 82.1 Wed Mar 19 23:23:18 CET 2008
9 - update documentation here and there: add a large section
10 about utf8/latin1/ascii flags, add a security consideration
11 and extend and clarify the JSON and YAML section.
12 - medium speed enhancements when encoding/decoding non-ascii chars.
13 - minor speedup in number encoding case.
14 - extend and clarify the section on incompatibilities
15 between YAML and JSON.
16 - switch to static inline from just inline when using gcc.
17 - add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
18 - fix some issues with UV to JSON conversion of unknown impact.
19 - published the yahoo locals search result used in benchmarks as the
20 original url changes so comparison is impossible.
21
222.01 Wed Dec 5 11:40:28 CET 2007
23 - INCOMPATIBLE API CHANGE: to_json and from_json have been
24 renamed to encode_json/decode_json for JSON.pm compatibility.
25 The old functions croak and might be replaced by JSON.pm
26 comaptible versions in some later release.
27
282.0 Tue Dec 4 11:30:46 CET 2007
29 - this is supposed to be the first version of JSON::XS
30 compatible with version 2.0+ of the JSON module.
31 Using the JSON module as frontend to JSON::XS should be
32 as fast as using JSON::XS directly, so consider using it
33 instead.
34 - added get_* methods for all "simple" options.
35 - make JSON::XS subclassable.
36
371.53 Tue Nov 13 23:58:33 CET 2007
38 - minor doc clarifications.
39 - fixed many doc typos (patch by Thomas L. Shinnick).
40
411.52 Mon Oct 15 03:22:06 CEST 2007
42 - remove =encoding pod directive again, it confuses too many pod
43 parsers :/.
44
451.51 Sat Oct 13 03:55:56 CEST 2007
46 - encode empty arrays/hashes in a compact way when pretty is enabled.
47 - apparently JSON::XS was used to find some bugs in the
48 JSON_checker testsuite, so add (the corrected) JSON_checker tests to
49 the testsuite.
50 - quite a bit of doc updates/extension.
51 - require 5.8.2, as this seems to be the first unicode-stable version.
52
531.5 Tue Aug 28 04:05:38 CEST 2007
54 - add support for tied hashes, based on ideas and testcase by
55 Marcus Holland-Moritz.
56 - implemented relaxed parsing mode where some extensions are being
57 accepted. generation is still JSON-only.
58
591.44 Wed Aug 22 01:02:44 CEST 2007
60 - very experimental process-emulation support, slowing everything down.
61 the horribly broken perl threads are still not supported - YMMV.
62
631.43 Thu Jul 26 13:26:37 CEST 2007
64 - convert big json numbers exclusively consisting of digits to NV
65 only when there is no loss of precision, otherwise to string.
66
671.42 Tue Jul 24 00:51:18 CEST 2007
68 - fix a crash caused by not handling missing array elements
69 (report and testcase by Jay Kuri).
70
711.41 Tue Jul 10 18:21:44 CEST 2007
72 - fix compilation with NDEBUG (assert side-effect),
73 affects convert_blessed only.
74 - fix a bug in decode filters calling ENTER; SAVETMPS;
75 one time too often.
76 - catch a typical error in TO_JSON methods.
77 - antique-ised XS.xs again to work with outdated
78 C compilers (windows...).
79
801.4 Mon Jul 2 10:06:30 CEST 2007
81 - add convert_blessed setting.
82 - encode did not catch all blessed objects, encoding their
83 contents in most cases. This has been fixed by introducing
84 the allow_blessed setting.
85 - added filter_json_object and filter_json_single_key_object
86 settings that specify a callback to be called when
87 all/specific json objects are encountered.
88 - assume that most object keys are simple ascii words and
89 optimise this case, penalising the general case. This can
90 speed up decoding by 30% in typical cases and gives
91 a smaller and faster perl hash.
92 - implemented simpleminded, optional resource size checking
93 in decode_json.
94 - remove objToJson/jsonToObj aliases, as the next version
95 of JSON will not have them either.
96 - bit the bullet and converted the very simple json object
97 into a more complex one.
98 - work around a bug where perl wrongly claims an integer
99 is not an integer.
100 - unbundle JSON::XS::Boolean into own pm file so Storable
101 and similar modules can resolve the overloading when thawing.
102
1031.3 Sun Jun 24 01:55:02 CEST 2007
104 - make JSON::XS::true and false special overloaded objects
105 and return those instead of 1 and 0 for those json atoms
106 (JSON::PP compatibility is NOT achieved yet).
107 - add JSON::XS::is_bool predicate to test for those special
108 values.
109 - add a reference to
110 http://jpsykes.com/47/practical-csrf-and-json-security.
111 - removed require 5.8.8 again, it is just not very expert-friendly.
112 Also try to be more compatible with slightly older versions,
113 which are not recommended (because they are buggy).
114
1151.24 Mon Jun 11 05:40:49 CEST 2007
116 - added informative section on JSON-as-YAML.
117 - get rid of some c99-isms again.
118 - localise dec->cur in decode_str, speeding up
119 string decoding considerably (>15% on my amd64 + gcc).
120 - increased SHORT_STRING_LEN to 16kb: stack space is
121 usually plenty, and this actually saves memory
122 when !shrinking as short strings will fit perfectly.
123
1241.23 Wed Jun 6 20:13:06 CEST 2007
125 - greatly improved small integer encoding and decoding speed.
126 - implement a number of µ-optimisations.
127 - updated benchmarks.
128
1291.22 Thu May 24 00:07:25 CEST 2007
130 - require 5.8.8 explicitly as older perls do not seem to offer
131 the required macros.
132 - possibly made it compile on so-called C compilers by microsoft.
133
1341.21 Wed May 9 18:40:32 CEST 2007
135 - character offset reported for trailing garbage was random.
136
1371.2 Wed May 9 18:35:01 CEST 2007
138 - decode did not work with magical scalars (doh!).
139 - added latin1 flag to produce JSON texts in the latin1 subset
140 of unicode.
141 - flag trailing garbage as error.
142 - new decode_prefix method that returns the number
143 of characters consumed by a decode.
144 - max octets/char in perls UTF-X is actually 13, not 11,
145 as pointed out by Glenn Linderman.
146 - fixed typoe reported by YAMASHINA Hio.
147
1481.11 Mon Apr 9 07:05:49 CEST 2007
149 - properly 0-terminate sv's returned by encode to help
150 C libraries that expect that 0 to be there.
151 - partially "port" JSON from C to microsofts fucking broken
152 pseudo-C. They should be burned to the ground for pissing
153 on standards. And I should be stoned for even trying to
154 support this filthy excuse for a c compiler.
155
1561.1 Wed Apr 4 01:45:00 CEST 2007
157 - clarify documentation (pointed out by Quinn Weaver).
158 - decode_utf8 sometimes did not correctly flag errors,
159 leading to segfaults.
160 - further reduced default nesting depth to 512 due to the test
161 failure by that anonymous "chris" whose e-mail address seems
162 to be impossible to get. Tests on other freebsd systems indicate
163 that this is likely a problem in his/her configuration and not this
164 module.
165 - renamed json => JSON in error messages.
166 - corrected the character offset in some error messages.
167
1681.01 Sat Mar 31 16:15:40 CEST 2007
169 - do not segfault when from_json/decode gets passed
170 a non-string object (reported by Florian Ragwitz).
171 This has no effect on normal operation.
172
1731.0 Thu Mar 29 04:43:34 CEST 2007
174 - the long awaited (by me) 1.0 version.
175 - add \0 (JSON::XS::false) and \1 (JSON::XS::true) mappings to JSON
176 true and false.
177 - add some more notes to shrink, as suggested by Alex Efros.
178 - improve testsuite.
179 - halve the default nesting depth limit, to hopefully make it
180 work on Freebsd (unfortunately, the cpan tester did not
181 send me his report, so I cannot ask about the stack limit on fbsd).
182
1830.8 Mon Mar 26 00:10:48 CEST 2007
184 - fix a memleak when decoding hashes.
185 - export jsonToBj and objToJson as aliases
186 to to_json and from_json, to reduce incompatibilities
187 between JSON/JSON::PC and JSON::XS. (experimental).
188 - implement a maximum nesting depth for both en- and de-coding.
189 - added a security considerations sections.
190
1910.7 Sun Mar 25 01:46:30 CET 2007
192 - code cleanup.
193 - fix a memory overflow bug when indenting.
194 - pretty-printing now up to 15% faster.
195 - improve decoding speed of strings by
196 up to 50% by specialcasing short strings.
197 - further decoding speedups for strings using
198 lots of \u escapes.
199 - improve utf8 decoding speed for U+80 .. U+7FF.
200
2010.5 Sat Mar 24 20:41:51 CET 2007
202 - added the UTF-16 encoding example hinted at in previous
203 versions.
204 - minor documentation fixes.
205 - fix a bug in and optimise canonicalising fastpath
206 (reported by Craig Manley).
207 - remove a subtest that breaks with bleadperl (reported
208 by Andreas König).
209
2100.31 Sat Mar 24 02:14:34 CET 2007
211 - documentation updates.
212 - do some casting to hopefully fix Andreas' problem.
213 - nuke bogus json rpc stuff.

232 - improve the "no bytes" and "no warnings" hacks in
233 case the called functions do... stuff.
234 - croak when encoding to ascii and an out-of-range
235 (non-unicode) codepoint is encountered.
