1Revision history for Perl extension JSON::XS 1Revision history for Perl extension JSON::XS
2 2
3TODO: maybe use some overload magic to decode true and false into something 3 - update documentation here and there, add a large section
4 not 0 or 1 in perl. or use attached magic? 4 about utf8/latin1/ascii flags, add a security consideration.
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.
5 12
6investigate the possibility of a yaml-compatible output format. 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.

81.24 192.0 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
9 - added informative section on JSON-as-YAML. 107 - added informative section on JSON-as-YAML.
108 - get rid of some c99-isms again.
10 - localise dec->cur in decode_str, speeding up 109 - localise dec->cur in decode_str, speeding up
11 string decoding considerably (>15% on my amd64 + gcc). 110 string decoding considerably (>15% on my amd64 + gcc).
12 - increased SHORT_STRING_LEN to 16kb: stack space is 111 - increased SHORT_STRING_LEN to 16kb: stack space is
13 usually plenty, and this actually saves memory 112 usually plenty, and this actually saves memory
14 when !shrinking. 113 when !shrinking as short strings will fit perfectly.
