3TODO: document conversion algorithm 3 - moved down =encoding directive a bit, too much breaks if its the first
4 pod directive :/.
4 5
50.3 62.1 Wed Mar 19 23:23:18 CET 2008
7 - update documentation here and there: add a large section
8 about utf8/latin1/ascii flags, add a security consideration
9 and extend and clarify the JSON and YAML section.
10 - medium speed enhancements when encoding/decoding non-ascii chars.
11 - minor speedup in number encoding case.
12 - extend and clarify the section on incompatibilities
13 between YAML and JSON.
14 - switch to static inline from just inline when using gcc.
15 - add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
16 - fix some issues with UV to JSON conversion of unknown impact.
17 - published the yahoo locals search result used in benchmarks as the
18 original url changes so comparison is impossible.
19
202.01 Wed Dec 5 11:40:28 CET 2007
21 - INCOMPATIBLE API CHANGE: to_json and from_json have been
22 renamed to encode_json/decode_json for JSON.pm compatibility.
23 The old functions croak and might be replaced by JSON.pm
24 comaptible versions in some later release.
25
262.0 Tue Dec 4 11:30:46 CET 2007
27 - this is supposed to be the first version of JSON::XS
28 compatible with version 2.0+ of the JSON module.
29 Using the JSON module as frontend to JSON::XS should be
30 as fast as using JSON::XS directly, so consider using it
31 instead.
32 - added get_* methods for all "simple" options.
33 - make JSON::XS subclassable.
34
351.53 Tue Nov 13 23:58:33 CET 2007
36 - minor doc clarifications.
37 - fixed many doc typos (patch by Thomas L. Shinnick).
38
391.52 Mon Oct 15 03:22:06 CEST 2007
40 - remove =encoding pod directive again, it confuses too many pod
41 parsers :/.
42
431.51 Sat Oct 13 03:55:56 CEST 2007
44 - encode empty arrays/hashes in a compact way when pretty is enabled.
45 - apparently JSON::XS was used to find some bugs in the
46 JSON_checker testsuite, so add (the corrected) JSON_checker tests to
47 the testsuite.
48 - quite a bit of doc updates/extension.
49 - require 5.8.2, as this seems to be the first unicode-stable version.
50
511.5 Tue Aug 28 04:05:38 CEST 2007
52 - add support for tied hashes, based on ideas and testcase by
53 Marcus Holland-Moritz.
54 - implemented relaxed parsing mode where some extensions are being
55 accepted. generation is still JSON-only.
56
571.44 Wed Aug 22 01:02:44 CEST 2007
58 - very experimental process-emulation support, slowing everything down.
59 the horribly broken perl threads are still not supported - YMMV.
60
611.43 Thu Jul 26 13:26:37 CEST 2007
62 - convert big json numbers exclusively consisting of digits to NV
63 only when there is no loss of precision, otherwise to string.
64
651.42 Tue Jul 24 00:51:18 CEST 2007
66 - fix a crash caused by not handling missing array elements
67 (report and testcase by Jay Kuri).
68
691.41 Tue Jul 10 18:21:44 CEST 2007
70 - fix compilation with NDEBUG (assert side-effect),
71 affects convert_blessed only.
72 - fix a bug in decode filters calling ENTER; SAVETMPS;
73 one time too often.
74 - catch a typical error in TO_JSON methods.
75 - antique-ised XS.xs again to work with outdated
76 C compilers (windows...).
77
781.4 Mon Jul 2 10:06:30 CEST 2007
79 - add convert_blessed setting.
80 - encode did not catch all blessed objects, encoding their
81 contents in most cases. This has been fixed by introducing
82 the allow_blessed setting.
83 - added filter_json_object and filter_json_single_key_object
84 settings that specify a callback to be called when
85 all/specific json objects are encountered.
86 - assume that most object keys are simple ascii words and
87 optimise this case, penalising the general case. This can
88 speed up decoding by 30% in typical cases and gives
89 a smaller and faster perl hash.
90 - implemented simpleminded, optional resource size checking
91 in decode_json.
92 - remove objToJson/jsonToObj aliases, as the next version
93 of JSON will not have them either.
94 - bit the bullet and converted the very simple json object
95 into a more complex one.
96 - work around a bug where perl wrongly claims an integer
97 is not an integer.
98 - unbundle JSON::XS::Boolean into own pm file so Storable
99 and similar modules can resolve the overloading when thawing.
100
1011.3 Sun Jun 24 01:55:02 CEST 2007
102 - make JSON::XS::true and false special overloaded objects
103 and return those instead of 1 and 0 for those json atoms
104 (JSON::PP compatibility is NOT achieved yet).
105 - add JSON::XS::is_bool predicate to test for those special
106 values.
107 - add a reference to
108 http://jpsykes.com/47/practical-csrf-and-json-security.
109 - removed require 5.8.8 again, it is just not very expert-friendly.
110 Also try to be more compatible with slightly older versions,
111 which are not recommended (because they are buggy).
112
1131.24 Mon Jun 11 05:40:49 CEST 2007
114 - added informative section on JSON-as-YAML.
115 - get rid of some c99-isms again.
116 - localise dec->cur in decode_str, speeding up
117 string decoding considerably (>15% on my amd64 + gcc).
118 - increased SHORT_STRING_LEN to 16kb: stack space is
119 usually plenty, and this actually saves memory
120 when !shrinking as short strings will fit perfectly.
121
1221.23 Wed Jun 6 20:13:06 CEST 2007
123 - greatly improved small integer encoding and decoding speed.
124 - implement a number of µ-optimisations.
125 - updated benchmarks.
126
1271.22 Thu May 24 00:07:25 CEST 2007
128 - require 5.8.8 explicitly as older perls do not seem to offer
129 the required macros.
130 - possibly made it compile on so-called C compilers by microsoft.
131
1321.21 Wed May 9 18:40:32 CEST 2007
133 - character offset reported for trailing garbage was random.
134
1351.2 Wed May 9 18:35:01 CEST 2007
136 - decode did not work with magical scalars (doh!).
137 - added latin1 flag to produce JSON texts in the latin1 subset
138 of unicode.
139 - flag trailing garbage as error.
140 - new decode_prefix method that returns the number
141 of characters consumed by a decode.
142 - max octets/char in perls UTF-X is actually 13, not 11,
143 as pointed out by Glenn Linderman.
144 - fixed typoe reported by YAMASHINA Hio.
145
1461.11 Mon Apr 9 07:05:49 CEST 2007
147 - properly 0-terminate sv's returned by encode to help
148 C libraries that expect that 0 to be there.
149 - partially "port" JSON from C to microsofts fucking broken
150 pseudo-C. They should be burned to the ground for pissing
151 on standards. And I should be stoned for even trying to
152 support this filthy excuse for a c compiler.
153
1541.1 Wed Apr 4 01:45:00 CEST 2007
155 - clarify documentation (pointed out by Quinn Weaver).
156 - decode_utf8 sometimes did not correctly flag errors,
157 leading to segfaults.
158 - further reduced default nesting depth to 512 due to the test
159 failure by that anonymous "chris" whose e-mail address seems
160 to be impossible to get. Tests on other freebsd systems indicate
161 that this is likely a problem in his/her configuration and not this
162 module.
163 - renamed json => JSON in error messages.
164 - corrected the character offset in some error messages.
165
1661.01 Sat Mar 31 16:15:40 CEST 2007
167 - do not segfault when from_json/decode gets passed
168 a non-string object (reported by Florian Ragwitz).
169 This has no effect on normal operation.
170
1711.0 Thu Mar 29 04:43:34 CEST 2007
172 - the long awaited (by me) 1.0 version.
173 - add \0 (JSON::XS::false) and \1 (JSON::XS::true) mappings to JSON
174 true and false.
175 - add some more notes to shrink, as suggested by Alex Efros.
176 - improve testsuite.
177 - halve the default nesting depth limit, to hopefully make it
178 work on Freebsd (unfortunately, the cpan tester did not
179 send me his report, so I cannot ask about the stack limit on fbsd).
180
1810.8 Mon Mar 26 00:10:48 CEST 2007
182 - fix a memleak when decoding hashes.
183 - export jsonToBj and objToJson as aliases
184 to to_json and from_json, to reduce incompatibilities
185 between JSON/JSON::PC and JSON::XS. (experimental).
186 - implement a maximum nesting depth for both en- and de-coding.
187 - added a security considerations sections.
188
1890.7 Sun Mar 25 01:46:30 CET 2007
190 - code cleanup.
191 - fix a memory overflow bug when indenting.
192 - pretty-printing now up to 15% faster.
193 - improve decoding speed of strings by
194 up to 50% by specialcasing short strings.
195 - further decoding speedups for strings using
196 lots of \u escapes.
197 - improve utf8 decoding speed for U+80 .. U+7FF.
198
1990.5 Sat Mar 24 20:41:51 CET 2007
200 - added the UTF-16 encoding example hinted at in previous
201 versions.
202 - minor documentation fixes.
203 - fix a bug in and optimise canonicalising fastpath
204 (reported by Craig Manley).
205 - remove a subtest that breaks with bleadperl (reported
206 by Andreas König).
207
2080.31 Sat Mar 24 02:14:34 CET 2007
209 - documentation updates.
210 - do some casting to hopefully fix Andreas' problem.
211 - nuke bogus json rpc stuff.

217 - documented mapping from json to perl and vice versa.
218 - improved the documentation by adding more examples.

12 - when flag methods are called without enable argument 222 - when flag methods are called without enable argument
13 they will by default enable their flag. 223 they will by default enable their flag.

21 case the called functions do... stuff. 231 case the called functions do... stuff.
232 - croak when encoding to ascii and an out-of-range
233 (non-unicode) codepoint is encountered.
