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...) 3 - update documentation here and there, add a large section
4TODO: maybe simply use \0 and \1 as true/false when encoding (and overloaded/blessed versions thereof on 4 about utf8/latin1/ascii flags, add a security consideration.
5 decoding?) 5 - medium speed enhancements when encoding/decoding non-ascii chars.
6 - extend and clarify the section on incompatibilities
7 between YAML and JSON.
8 - switch to static inline from just inline when using gcc.
9 - add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
10 - published the yahoo locals search result used in benchmarks as the
11 original url changes so comparison is impossible.

132.01 Wed Dec 5 11:40:28 CET 2007
14 - INCOMPATIBLE API CHANGE: to_json and from_json have been
15 renamed to encode_json/decode_json for JSON.pm compatibility.
16 The old functions croak and might be replaced by JSON.pm
17 comaptible versions in some later release.
18
192.0 Tue Dec 4 11:30:46 CET 2007
20 - this is supposed to be the first version of JSON::XS
21 compatible with version 2.0+ of the JSON module.
22 Using the JSON module as frontend to JSON::XS should be
23 as fast as using JSON::XS directly, so consider using it
24 instead.
25 - added get_* methods for all "simple" options.
26 - make JSON::XS subclassable.
27
281.53 Tue Nov 13 23:58:33 CET 2007
29 - minor doc clarifications.
30 - fixed many doc typos (patch by Thomas L. Shinnick).
31
321.52 Mon Oct 15 03:22:06 CEST 2007
33 - remove =encoding pod directive again, it confuses too many pod
34 parsers :/.
35
361.51 Sat Oct 13 03:55:56 CEST 2007
37 - encode empty arrays/hashes in a compact way when pretty is enabled.
38 - apparently JSON::XS was used to find some bugs in the
39 JSON_checker testsuite, so add (the corrected) JSON_checker tests to
40 the testsuite.
41 - quite a bit of doc updates/extension.
42 - require 5.8.2, as this seems to be the first unicode-stable version.
43
441.5 Tue Aug 28 04:05:38 CEST 2007
45 - add support for tied hashes, based on ideas and testcase by
46 Marcus Holland-Moritz.
47 - implemented relaxed parsing mode where some extensions are being
48 accepted. generation is still JSON-only.
49
501.44 Wed Aug 22 01:02:44 CEST 2007
51 - very experimental process-emulation support, slowing everything down.
52 the horribly broken perl threads are still not supported - YMMV.
53
541.43 Thu Jul 26 13:26:37 CEST 2007
55 - convert big json numbers exclusively consisting of digits to NV
56 only when there is no loss of precision, otherwise to string.
57
581.42 Tue Jul 24 00:51:18 CEST 2007
59 - fix a crash caused by not handling missing array elements
60 (report and testcase by Jay Kuri).
61
621.41 Tue Jul 10 18:21:44 CEST 2007
63 - fix compilation with NDEBUG (assert side-effect),
64 affects convert_blessed only.
65 - fix a bug in decode filters calling ENTER; SAVETMPS;
66 one time too often.
67 - catch a typical error in TO_JSON methods.
68 - antique-ised XS.xs again to work with outdated
69 C compilers (windows...).
70
711.4 Mon Jul 2 10:06:30 CEST 2007
72 - add convert_blessed setting.
73 - encode did not catch all blessed objects, encoding their
74 contents in most cases. This has been fixed by introducing
75 the allow_blessed setting.
76 - added filter_json_object and filter_json_single_key_object
77 settings that specify a callback to be called when
78 all/specific json objects are encountered.
79 - assume that most object keys are simple ascii words and
80 optimise this case, penalising the general case. This can
81 speed up decoding by 30% in typical cases and gives
82 a smaller and faster perl hash.
83 - implemented simpleminded, optional resource size checking
84 in decode_json.
85 - remove objToJson/jsonToObj aliases, as the next version
86 of JSON will not have them either.
87 - bit the bullet and converted the very simple json object
88 into a more complex one.
89 - work around a bug where perl wrongly claims an integer
90 is not an integer.
91 - unbundle JSON::XS::Boolean into own pm file so Storable
92 and similar modules can resolve the overloading when thawing.
93
941.3 Sun Jun 24 01:55:02 CEST 2007
95 - make JSON::XS::true and false special overloaded objects
96 and return those instead of 1 and 0 for those json atoms
97 (JSON::PP compatibility is NOT achieved yet).
98 - add JSON::XS::is_bool predicate to test for those special
99 values.
100 - add a reference to
101 http://jpsykes.com/47/practical-csrf-and-json-security.
102 - removed require 5.8.8 again, it is just not very expert-friendly.
103 Also try to be more compatible with slightly older versions,
104 which are not recommended (because they are buggy).
105
1061.24 Mon Jun 11 05:40:49 CEST 2007
107 - added informative section on JSON-as-YAML.
108 - get rid of some c99-isms again.
109 - localise dec->cur in decode_str, speeding up
110 string decoding considerably (>15% on my amd64 + gcc).
111 - increased SHORT_STRING_LEN to 16kb: stack space is
112 usually plenty, and this actually saves memory
113 when !shrinking as short strings will fit perfectly.
114
1151.23 Wed Jun 6 20:13:06 CEST 2007
116 - greatly improved small integer encoding and decoding speed.
117 - implement a number of µ-optimisations.
118 - updated benchmarks.
119
1201.22 Thu May 24 00:07:25 CEST 2007
121 - require 5.8.8 explicitly as older perls do not seem to offer
122 the required macros.
123 - possibly made it compile on so-called C compilers by microsoft.
124
1251.21 Wed May 9 18:40:32 CEST 2007
126 - character offset reported for trailing garbage was random.
127
1281.2 Wed May 9 18:35:01 CEST 2007
129 - decode did not work with magical scalars (doh!).
130 - added latin1 flag to produce JSON texts in the latin1 subset
131 of unicode.
132 - flag trailing garbage as error.
133 - new decode_prefix method that returns the number
134 of characters consumed by a decode.
135 - max octets/char in perls UTF-X is actually 13, not 11,
136 as pointed out by Glenn Linderman.
137 - fixed typoe reported by YAMASHINA Hio.
138
1391.11 Mon Apr 9 07:05:49 CEST 2007
140 - properly 0-terminate sv's returned by encode to help
141 C libraries that expect that 0 to be there.
142 - partially "port" JSON from C to microsofts fucking broken
143 pseudo-C. They should be burned to the ground for pissing
144 on standards. And I should be stoned for even trying to
145 support this filthy excuse for a c compiler.
146
1471.1 Wed Apr 4 01:45:00 CEST 2007
148 - clarify documentation (pointed out by Quinn Weaver).
149 - decode_utf8 sometimes did not correctly flag errors,
150 leading to segfaults.
151 - further reduced default nesting depth to 512 due to the test
152 failure by that anonymous "chris" whose e-mail address seems
153 to be impossible to get. Tests on other freebsd systems indicate
154 that this is likely a problem in his/her configuration and not this
155 module.
156 - renamed json => JSON in error messages.
157 - corrected the character offset in some error messages.
158
1591.01 Sat Mar 31 16:15:40 CEST 2007
160 - do not segfault when from_json/decode gets passed
161 a non-string object (reported by Florian Ragwitz).
162 This has no effect on normal operation.
163
1641.0 Thu Mar 29 04:43:34 CEST 2007
165 - the long awaited (by me) 1.0 version.
166 - add \0 (JSON::XS::false) and \1 (JSON::XS::true) mappings to JSON
167 true and false.
168 - add some more notes to shrink, as suggested by Alex Efros.
169 - improve testsuite.
170 - halve the default nesting depth limit, to hopefully make it
171 work on Freebsd (unfortunately, the cpan tester did not
172 send me his report, so I cannot ask about the stack limit on fbsd).
173
1740.8 Mon Mar 26 00:10:48 CEST 2007
175 - fix a memleak when decoding hashes.
176 - export jsonToBj and objToJson as aliases
177 to to_json and from_json, to reduce incompatibilities
178 between JSON/JSON::PC and JSON::XS. (experimental).
179 - implement a maximum nesting depth for both en- and de-coding.
180 - added a security considerations sections.
181
1820.7 Sun Mar 25 01:46:30 CET 2007
183 - code cleanup.
184 - fix a memory overflow bug when indenting.
185 - pretty-printing now up to 15% faster.
186 - improve decoding speed of strings by
187 up to 50% by specialcasing short strings.
188 - further decoding speedups for strings using
189 lots of \u escapes.
190 - improve utf8 decoding speed for U+80 .. U+7FF.
191
1920.5 Sat Mar 24 20:41:51 CET 2007
193 - added the UTF-16 encoding example hinted at in previous
194 versions.
195 - minor documentation fixes.
196 - fix a bug in and optimise canonicalising fastpath
197 (reported by Craig Manley).
198 - remove a subtest that breaks with bleadperl (reported
199 by Andreas König).
200
2010.31 Sat Mar 24 02:14:34 CET 2007
202 - documentation updates.
203 - do some casting to hopefully fix Andreas' problem.
204 - nuke bogus json rpc stuff.
6 205
70.3 Fri Mar 23 19:33:21 CET 2007 2060.3 Fri Mar 23 19:33:21 CET 2007
8 - remove spurious PApp::Util reference (John McNamara). 207 - remove spurious PApp::Util reference (John McNamara).
9 - adapted lots of tests from other json modules 208 - adapted lots of tests from other json modules
