1Revision history for Perl extension JSON::XS 1Revision history for Perl extension JSON::XS
2 2
30.3 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
92.1 Wed Mar 19 23:23:18 CET 2008
10 - update documentation here and there: add a large section
11 about utf8/latin1/ascii flags, add a security consideration
12 and extend and clarify the JSON and YAML section.
13 - medium speed enhancements when encoding/decoding non-ascii chars.
14 - minor speedup in number encoding case.
15 - extend and clarify the section on incompatibilities
16 between YAML and JSON.
17 - switch to static inline from just inline when using gcc.
18 - add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
19 - fix some issues with UV to JSON conversion of unknown impact.
20 - published the yahoo locals search result used in benchmarks as the
21 original url changes so comparison is impossible.
22
232.01 Wed Dec 5 11:40:28 CET 2007
24 - INCOMPATIBLE API CHANGE: to_json and from_json have been
25 renamed to encode_json/decode_json for JSON.pm compatibility.
26 The old functions croak and might be replaced by JSON.pm
27 comaptible versions in some later release.
28
292.0 Tue Dec 4 11:30:46 CET 2007
30 - this is supposed to be the first version of JSON::XS
31 compatible with version 2.0+ of the JSON module.
32 Using the JSON module as frontend to JSON::XS should be
33 as fast as using JSON::XS directly, so consider using it
34 instead.
35 - added get_* methods for all "simple" options.
36 - make JSON::XS subclassable.
37
381.53 Tue Nov 13 23:58:33 CET 2007
39 - minor doc clarifications.
40 - fixed many doc typos (patch by Thomas L. Shinnick).
41
421.52 Mon Oct 15 03:22:06 CEST 2007
43 - remove =encoding pod directive again, it confuses too many pod
44 parsers :/.
45
461.51 Sat Oct 13 03:55:56 CEST 2007
47 - encode empty arrays/hashes in a compact way when pretty is enabled.
48 - apparently JSON::XS was used to find some bugs in the
49 JSON_checker testsuite, so add (the corrected) JSON_checker tests to
50 the testsuite.
51 - quite a bit of doc updates/extension.
52 - require 5.8.2, as this seems to be the first unicode-stable version.
53
541.5 Tue Aug 28 04:05:38 CEST 2007
55 - add support for tied hashes, based on ideas and testcase by
56 Marcus Holland-Moritz.
57 - implemented relaxed parsing mode where some extensions are being
58 accepted. generation is still JSON-only.
59
601.44 Wed Aug 22 01:02:44 CEST 2007
61 - very experimental process-emulation support, slowing everything down.
62 the horribly broken perl threads are still not supported - YMMV.
63
641.43 Thu Jul 26 13:26:37 CEST 2007
65 - convert big json numbers exclusively consisting of digits to NV
66 only when there is no loss of precision, otherwise to string.
67
681.42 Tue Jul 24 00:51:18 CEST 2007
69 - fix a crash caused by not handling missing array elements
70 (report and testcase by Jay Kuri).
71
721.41 Tue Jul 10 18:21:44 CEST 2007
73 - fix compilation with NDEBUG (assert side-effect),
74 affects convert_blessed only.
75 - fix a bug in decode filters calling ENTER; SAVETMPS;
76 one time too often.
77 - catch a typical error in TO_JSON methods.
78 - antique-ised XS.xs again to work with outdated
79 C compilers (windows...).
80
811.4 Mon Jul 2 10:06:30 CEST 2007
82 - add convert_blessed setting.
83 - encode did not catch all blessed objects, encoding their
84 contents in most cases. This has been fixed by introducing
85 the allow_blessed setting.
86 - added filter_json_object and filter_json_single_key_object
87 settings that specify a callback to be called when
88 all/specific json objects are encountered.
89 - assume that most object keys are simple ascii words and
90 optimise this case, penalising the general case. This can
91 speed up decoding by 30% in typical cases and gives
92 a smaller and faster perl hash.
93 - implemented simpleminded, optional resource size checking
94 in decode_json.
95 - remove objToJson/jsonToObj aliases, as the next version
96 of JSON will not have them either.
97 - bit the bullet and converted the very simple json object
98 into a more complex one.
99 - work around a bug where perl wrongly claims an integer
100 is not an integer.
101 - unbundle JSON::XS::Boolean into own pm file so Storable
102 and similar modules can resolve the overloading when thawing.
103
1041.3 Sun Jun 24 01:55:02 CEST 2007
105 - make JSON::XS::true and false special overloaded objects
106 and return those instead of 1 and 0 for those json atoms
107 (JSON::PP compatibility is NOT achieved yet).
108 - add JSON::XS::is_bool predicate to test for those special
109 values.
110 - add a reference to
111 http://jpsykes.com/47/practical-csrf-and-json-security.
112 - removed require 5.8.8 again, it is just not very expert-friendly.
113 Also try to be more compatible with slightly older versions,
114 which are not recommended (because they are buggy).
115
1161.24 Mon Jun 11 05:40:49 CEST 2007
117 - added informative section on JSON-as-YAML.
118 - get rid of some c99-isms again.
119 - localise dec->cur in decode_str, speeding up
120 string decoding considerably (>15% on my amd64 + gcc).
121 - increased SHORT_STRING_LEN to 16kb: stack space is
122 usually plenty, and this actually saves memory
123 when !shrinking as short strings will fit perfectly.
124
1251.23 Wed Jun 6 20:13:06 CEST 2007
126 - greatly improved small integer encoding and decoding speed.
127 - implement a number of µ-optimisations.
128 - updated benchmarks.
129
1301.22 Thu May 24 00:07:25 CEST 2007
131 - require 5.8.8 explicitly as older perls do not seem to offer
132 the required macros.
133 - possibly made it compile on so-called C compilers by microsoft.
134
1351.21 Wed May 9 18:40:32 CEST 2007
136 - character offset reported for trailing garbage was random.
137
1381.2 Wed May 9 18:35:01 CEST 2007
139 - decode did not work with magical scalars (doh!).
140 - added latin1 flag to produce JSON texts in the latin1 subset
141 of unicode.
142 - flag trailing garbage as error.
143 - new decode_prefix method that returns the number
144 of characters consumed by a decode.
145 - max octets/char in perls UTF-X is actually 13, not 11,
146 as pointed out by Glenn Linderman.
147 - fixed typoe reported by YAMASHINA Hio.
148
1491.11 Mon Apr 9 07:05:49 CEST 2007
150 - properly 0-terminate sv's returned by encode to help
151 C libraries that expect that 0 to be there.
152 - partially "port" JSON from C to microsofts fucking broken
153 pseudo-C. They should be burned to the ground for pissing
154 on standards. And I should be stoned for even trying to
155 support this filthy excuse for a c compiler.
156
1571.1 Wed Apr 4 01:45:00 CEST 2007
158 - clarify documentation (pointed out by Quinn Weaver).
159 - decode_utf8 sometimes did not correctly flag errors,
160 leading to segfaults.
161 - further reduced default nesting depth to 512 due to the test
162 failure by that anonymous "chris" whose e-mail address seems
163 to be impossible to get. Tests on other freebsd systems indicate
164 that this is likely a problem in his/her configuration and not this
165 module.
166 - renamed json => JSON in error messages.
167 - corrected the character offset in some error messages.
168
1691.01 Sat Mar 31 16:15:40 CEST 2007
170 - do not segfault when from_json/decode gets passed
171 a non-string object (reported by Florian Ragwitz).
172 This has no effect on normal operation.
173
1741.0 Thu Mar 29 04:43:34 CEST 2007
175 - the long awaited (by me) 1.0 version.
176 - add \0 (JSON::XS::false) and \1 (JSON::XS::true) mappings to JSON
177 true and false.
178 - add some more notes to shrink, as suggested by Alex Efros.
179 - improve testsuite.
180 - halve the default nesting depth limit, to hopefully make it
181 work on Freebsd (unfortunately, the cpan tester did not
182 send me his report, so I cannot ask about the stack limit on fbsd).
183
1840.8 Mon Mar 26 00:10:48 CEST 2007
185 - fix a memleak when decoding hashes.
186 - export jsonToBj and objToJson as aliases
187 to to_json and from_json, to reduce incompatibilities
188 between JSON/JSON::PC and JSON::XS. (experimental).
189 - implement a maximum nesting depth for both en- and de-coding.
190 - added a security considerations sections.
191
1920.7 Sun Mar 25 01:46:30 CET 2007
193 - code cleanup.
194 - fix a memory overflow bug when indenting.
195 - pretty-printing now up to 15% faster.
196 - improve decoding speed of strings by
197 up to 50% by specialcasing short strings.
198 - further decoding speedups for strings using
199 lots of \u escapes.
200 - improve utf8 decoding speed for U+80 .. U+7FF.
201
2020.5 Sat Mar 24 20:41:51 CET 2007
203 - added the UTF-16 encoding example hinted at in previous
204 versions.
205 - minor documentation fixes.
206 - fix a bug in and optimise canonicalising fastpath
207 (reported by Craig Manley).
208 - remove a subtest that breaks with bleadperl (reported
209 by Andreas König).
210
2110.31 Sat Mar 24 02:14:34 CET 2007
212 - documentation updates.
213 - do some casting to hopefully fix Andreas' problem.
214 - nuke bogus json rpc stuff.
215
2160.3 Fri Mar 23 19:33:21 CET 2007
4 - remove spurious PApp::Util reference (John McNamara). 217 - remove spurious PApp::Util reference (John McNamara).
5 - adapted lots of tests from other json modules 218 - adapted lots of tests from other json modules
6 (idea by Chris Carline). 219 (idea by Chris Carline).
220 - documented mapping from json to perl and vice versa.
221 - improved the documentation by adding more examples.
7 - added short escaping forms, reducing the created 222 - added short escaping forms, reducing the created
8 json texts a bit. 223 json texts a bit.
9 - added shrink flag. 224 - added shrink flag.
10 - when flag methods are called without enable argument 225 - when flag methods are called without enable argument
11 they will by default enable their flag. 226 they will by default enable their flag.
12 - considerably improved string encoding speed (at least 227 - considerably improved string encoding speed (at least
13 with gcc 4). 228 with gcc 4).
229 - added a test that covers lots of different characters.
230 - clarified some error messages.
231 - error messages now use correct character offset
232 with F_UTF8.
233 - improve the "no bytes" and "no warnings" hacks in
234 case the called functions do... stuff.
235 - croak when encoding to ascii and an out-of-range
236 (non-unicode) codepoint is encountered.
