1Revision history for Perl extension JSON::XS 1Revision history for Perl extension JSON::XS
2 2
3TODO: allow a configurable recursion limit and/or or other forms of resource limiting (string size, memory usage...) 3implement incremental parsing mode (faked)
4TODO: maybe simply use \0 and \1 as true/false when encoding (and overloaded/blessed versions thereof on
5 decoding?)
6 4
70.3 5 - implemented and added a json_xs command line utility that can convert
6 from/to a number of serialisation formats - tell me if you need more.
7 - moved down =encoding directive a bit, too much breaks if its the first
8 pod directive :/.
9
102.1 Wed Mar 19 23:23:18 CET 2008
11 - update documentation here and there: add a large section
12 about utf8/latin1/ascii flags, add a security consideration
13 and extend and clarify the JSON and YAML section.
14 - medium speed enhancements when encoding/decoding non-ascii chars.
15 - minor speedup in number encoding case.
16 - extend and clarify the section on incompatibilities
17 between YAML and JSON.
18 - switch to static inline from just inline when using gcc.
19 - add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
20 - fix some issues with UV to JSON conversion of unknown impact.
21 - published the yahoo locals search result used in benchmarks as the
22 original url changes so comparison is impossible.
23
242.01 Wed Dec 5 11:40:28 CET 2007
25 - INCOMPATIBLE API CHANGE: to_json and from_json have been
26 renamed to encode_json/decode_json for JSON.pm compatibility.
27 The old functions croak and might be replaced by JSON.pm
28 comaptible versions in some later release.
29
302.0 Tue Dec 4 11:30:46 CET 2007
31 - this is supposed to be the first version of JSON::XS
32 compatible with version 2.0+ of the JSON module.
33 Using the JSON module as frontend to JSON::XS should be
34 as fast as using JSON::XS directly, so consider using it
35 instead.
36 - added get_* methods for all "simple" options.
37 - make JSON::XS subclassable.
38
391.53 Tue Nov 13 23:58:33 CET 2007
40 - minor doc clarifications.
41 - fixed many doc typos (patch by Thomas L. Shinnick).
42
431.52 Mon Oct 15 03:22:06 CEST 2007
44 - remove =encoding pod directive again, it confuses too many pod
45 parsers :/.
46
471.51 Sat Oct 13 03:55:56 CEST 2007
48 - encode empty arrays/hashes in a compact way when pretty is enabled.
49 - apparently JSON::XS was used to find some bugs in the
50 JSON_checker testsuite, so add (the corrected) JSON_checker tests to
51 the testsuite.
52 - quite a bit of doc updates/extension.
53 - require 5.8.2, as this seems to be the first unicode-stable version.
54
551.5 Tue Aug 28 04:05:38 CEST 2007
56 - add support for tied hashes, based on ideas and testcase by
57 Marcus Holland-Moritz.
58 - implemented relaxed parsing mode where some extensions are being
59 accepted. generation is still JSON-only.
60
611.44 Wed Aug 22 01:02:44 CEST 2007
62 - very experimental process-emulation support, slowing everything down.
63 the horribly broken perl threads are still not supported - YMMV.
64
651.43 Thu Jul 26 13:26:37 CEST 2007
66 - convert big json numbers exclusively consisting of digits to NV
67 only when there is no loss of precision, otherwise to string.
68
691.42 Tue Jul 24 00:51:18 CEST 2007
70 - fix a crash caused by not handling missing array elements
71 (report and testcase by Jay Kuri).
72
731.41 Tue Jul 10 18:21:44 CEST 2007
74 - fix compilation with NDEBUG (assert side-effect),
75 affects convert_blessed only.
76 - fix a bug in decode filters calling ENTER; SAVETMPS;
77 one time too often.
78 - catch a typical error in TO_JSON methods.
79 - antique-ised XS.xs again to work with outdated
80 C compilers (windows...).
81
821.4 Mon Jul 2 10:06:30 CEST 2007
83 - add convert_blessed setting.
84 - encode did not catch all blessed objects, encoding their
85 contents in most cases. This has been fixed by introducing
86 the allow_blessed setting.
87 - added filter_json_object and filter_json_single_key_object
88 settings that specify a callback to be called when
89 all/specific json objects are encountered.
90 - assume that most object keys are simple ascii words and
91 optimise this case, penalising the general case. This can
92 speed up decoding by 30% in typical cases and gives
93 a smaller and faster perl hash.
94 - implemented simpleminded, optional resource size checking
95 in decode_json.
96 - remove objToJson/jsonToObj aliases, as the next version
97 of JSON will not have them either.
98 - bit the bullet and converted the very simple json object
99 into a more complex one.
100 - work around a bug where perl wrongly claims an integer
101 is not an integer.
102 - unbundle JSON::XS::Boolean into own pm file so Storable
103 and similar modules can resolve the overloading when thawing.
104
1051.3 Sun Jun 24 01:55:02 CEST 2007
106 - make JSON::XS::true and false special overloaded objects
107 and return those instead of 1 and 0 for those json atoms
108 (JSON::PP compatibility is NOT achieved yet).
109 - add JSON::XS::is_bool predicate to test for those special
110 values.
111 - add a reference to
112 http://jpsykes.com/47/practical-csrf-and-json-security.
113 - removed require 5.8.8 again, it is just not very expert-friendly.
114 Also try to be more compatible with slightly older versions,
115 which are not recommended (because they are buggy).
116
1171.24 Mon Jun 11 05:40:49 CEST 2007
118 - added informative section on JSON-as-YAML.
119 - get rid of some c99-isms again.
120 - localise dec->cur in decode_str, speeding up
121 string decoding considerably (>15% on my amd64 + gcc).
122 - increased SHORT_STRING_LEN to 16kb: stack space is
123 usually plenty, and this actually saves memory
124 when !shrinking as short strings will fit perfectly.
125
1261.23 Wed Jun 6 20:13:06 CEST 2007
127 - greatly improved small integer encoding and decoding speed.
128 - implement a number of µ-optimisations.
129 - updated benchmarks.
130
1311.22 Thu May 24 00:07:25 CEST 2007
132 - require 5.8.8 explicitly as older perls do not seem to offer
133 the required macros.
134 - possibly made it compile on so-called C compilers by microsoft.
135
1361.21 Wed May 9 18:40:32 CEST 2007
137 - character offset reported for trailing garbage was random.
138
1391.2 Wed May 9 18:35:01 CEST 2007
140 - decode did not work with magical scalars (doh!).
141 - added latin1 flag to produce JSON texts in the latin1 subset
142 of unicode.
143 - flag trailing garbage as error.
144 - new decode_prefix method that returns the number
145 of characters consumed by a decode.
146 - max octets/char in perls UTF-X is actually 13, not 11,
147 as pointed out by Glenn Linderman.
148 - fixed typoe reported by YAMASHINA Hio.
149
1501.11 Mon Apr 9 07:05:49 CEST 2007
151 - properly 0-terminate sv's returned by encode to help
152 C libraries that expect that 0 to be there.
153 - partially "port" JSON from C to microsofts fucking broken
154 pseudo-C. They should be burned to the ground for pissing
155 on standards. And I should be stoned for even trying to
156 support this filthy excuse for a c compiler.
157
1581.1 Wed Apr 4 01:45:00 CEST 2007
159 - clarify documentation (pointed out by Quinn Weaver).
160 - decode_utf8 sometimes did not correctly flag errors,
161 leading to segfaults.
162 - further reduced default nesting depth to 512 due to the test
163 failure by that anonymous "chris" whose e-mail address seems
164 to be impossible to get. Tests on other freebsd systems indicate
165 that this is likely a problem in his/her configuration and not this
166 module.
167 - renamed json => JSON in error messages.
168 - corrected the character offset in some error messages.
169
1701.01 Sat Mar 31 16:15:40 CEST 2007
171 - do not segfault when from_json/decode gets passed
172 a non-string object (reported by Florian Ragwitz).
173 This has no effect on normal operation.
174
1751.0 Thu Mar 29 04:43:34 CEST 2007
176 - the long awaited (by me) 1.0 version.
177 - add \0 (JSON::XS::false) and \1 (JSON::XS::true) mappings to JSON
178 true and false.
179 - add some more notes to shrink, as suggested by Alex Efros.
180 - improve testsuite.
181 - halve the default nesting depth limit, to hopefully make it
182 work on Freebsd (unfortunately, the cpan tester did not
183 send me his report, so I cannot ask about the stack limit on fbsd).
184
1850.8 Mon Mar 26 00:10:48 CEST 2007
186 - fix a memleak when decoding hashes.
187 - export jsonToBj and objToJson as aliases
188 to to_json and from_json, to reduce incompatibilities
189 between JSON/JSON::PC and JSON::XS. (experimental).
190 - implement a maximum nesting depth for both en- and de-coding.
191 - added a security considerations sections.
192
1930.7 Sun Mar 25 01:46:30 CET 2007
194 - code cleanup.
195 - fix a memory overflow bug when indenting.
196 - pretty-printing now up to 15% faster.
197 - improve decoding speed of strings by
198 up to 50% by specialcasing short strings.
199 - further decoding speedups for strings using
200 lots of \u escapes.
201 - improve utf8 decoding speed for U+80 .. U+7FF.
202
2030.5 Sat Mar 24 20:41:51 CET 2007
204 - added the UTF-16 encoding example hinted at in previous
205 versions.
206 - minor documentation fixes.
207 - fix a bug in and optimise canonicalising fastpath
208 (reported by Craig Manley).
209 - remove a subtest that breaks with bleadperl (reported
210 by Andreas König).
211
2120.31 Sat Mar 24 02:14:34 CET 2007
213 - documentation updates.
214 - do some casting to hopefully fix Andreas' problem.
215 - nuke bogus json rpc stuff.
216
2170.3 Fri Mar 23 19:33:21 CET 2007
8 - remove spurious PApp::Util reference (John McNamara). 218 - remove spurious PApp::Util reference (John McNamara).
