9 | 4.0 Fri Nov 16 00:06:54 CET 2018 |
|
|
10 | - 4.0 pre-release, do not use other than for testing. |
|
|
11 | - SECURITY IMPLICATION: this release enables allow_nonref by default |
|
|
12 | for compatibnility with RFC 7159 and newer. See "old" vs. "new" |
|
|
13 | JSON under SECURITY CONSIDERATIONS. |
|
|
14 | - reworked the "old" vs. "new" JSON section. |
|
|
15 | - add ->boolean_values to provide the values to which booleans |
|
|
16 | decode (requested by Aristotle Pagaltzis). |
|
|
17 | - decode would wrongly accept ASCII NUL characters instead of |
|
|
18 | reporting them as trailing garbage. |
|
|
19 | - work around what smells like a perl bug w.r.t. exceptions |
|
|
20 | thrown in callbacks. |
|
|
21 | - incremental parser now more or less respects allow_nonref. |
|
|
22 | - json_xs json-pretty now enables canonical mode. |
|
|
23 | - add documentation section about I-JSON. |
|
|
24 | - minor documentation fixes/updates. |
|
|
25 | |
|
|
26 | 3.04 Thu Aug 17 04:30:47 CEST 2017 |
|
|
27 | - change exponential realloc algorithm on encoding and string decoding to be |
|
|
28 | really exponential (this helps slow/debugging allocators such as libumem) |
|
|
29 | (reported by Matthew Horsfall). |
|
|
30 | - string encoding would needlessly overallocate output space |
|
|
31 | (testcase by Matthew Horsfall). |
|
|
32 | - be very paranoid about extending buffer lengths and croak if buffers get too large, |
|
|
33 | which might (or might not) improve security. |
|
|
34 | - add cbor-packed type to json_xs. |
|
|
35 | - switch from YAML to YAML::XS in json_xs, as YAML is way too buggy and outdated. |
|
|
36 | |
|
|
37 | 3.03 Wed Nov 16 20:20:59 CET 2016 |
|
|
38 | - fix a bug introduced by a perl bug workaround that would cause |
|
|
39 | incremental parsing to fail with a sv_chop panic. |
|
|
40 | - json_xs: toformat failure error message fixed. |
|
|
41 | - json_xs: allow cyclic data structures in CBOR. |
|
|
42 | |
|
|
43 | 3.02 Fri Feb 26 22:45:20 CET 2016 |
|
|
44 | - allow_nonref now affects booleans (\1, $Types::Serialiser::Boolean) |
|
|
45 | as well (reported by Alex Efros). |
|
|
46 | - allow literal tabs in strings in relaxed mode (patch by |
|
|
47 | lubo.rintel@gooddata.com). |
|
|
48 | - support "cbor" format in json_xs tool. |
|
|
49 | - support (and fix) calling encode and decode in list context |
|
|
50 | (reported by Вадим Власов). |
|
|
51 | - work around a bug in older perls crashing when presented |
|
|
52 | with shared hash keys (Reini Urban). |
|
|
53 | - use stability canary. |
|
|
54 | |
|
|
55 | 3.01 Tue Oct 29 16:55:15 CET 2013 |
|
|
56 | - backport to perls < 5.18 (reported by Paul Howarth). |
|
|
57 | |
|
|
58 | 3.0 Tue Oct 29 01:35:37 CET 2013 |
|
|
59 | - implemented an object tagging extension (using the |
|
|
60 | Types::Serialiser serialisation protocol). |
|
|
61 | - reworked the documentation regarding object serialisation, |
|
|
62 | add a new OBJECT SERIALISATION section that explains th |
|
|
63 | whole process. |
|
|
64 | - new setting: allow_tags. |
|
|
65 | - switch to Types::Serialiser booleans. |
|
|
66 | - remove to_json/from_json. |
|
|
67 | - other minor improvements to the documentation. |
|
|
68 | |
|
|
69 | 2.34 Thu May 23 11:30:34 CEST 2013 |
|
|
70 | - work around bugs in perl 5.18 breaking more than 100 |
|
|
71 | widely used modules, without a fix in sight because |
|
|
72 | p5pers don't care about CPAN anymore. |
|
|
73 | - when canonicalising, only allocate up to 64 hash key |
|
|
74 | pointers on the stack. for larger hashes, use the heap, |
|
|
75 | to avoid using too much stackspace. |
|
|
76 | - discuss the problem with setlocale (reported by a few victims). |
|
|
77 | |
|
|
78 | 2.33 Wed Aug 1 21:03:52 CEST 2012 |
|
|
79 | - internal encode/decode XS wrappers did not expect stack |
|
|
80 | moves caused by callbacks (analyzed and testcase by Jesse Luehrs). |
|
|
81 | - add bencode as to/from option in bin/json_xs. |
|
|
82 | - add -e option to json_xs, and none and string in/out formats. |
|
|
83 | |
|
|
84 | 2.32 Thu Aug 11 19:06:38 CEST 2011 |
|
|
85 | - fix a bug in the initial whitespace accumulation. |
|
|
86 | |
|
|
87 | 2.31 Wed Jul 27 17:53:05 CEST 2011 |
|
|
88 | - don't accumulate initial whitespace in the incremental buffer |
|
|
89 | (this can be useful to allow whitespace-keepalive on a tcp |
|
|
90 | connection without triggering the max_size limit). |
|
|
91 | - properly croak on some invalid inputs that are not strings |
|
|
92 | (e.g. undef) when trying to decode a json text (reported |
|
|
93 | and analyzed by Goro Fuji). |
|
|
94 | |
|
|
95 | 2.3 Wed Aug 18 01:26:47 CEST 2010 |
|
|
96 | - make sure decoder doesn't change the decoding in the incremental |
|
|
97 | parser (testcase provided by Hendrik Schumacher). |
|
|
98 | - applied patch by DaTa for Data::Dumper support in json_xs. |
|
|
99 | - added -t dump support to json_xs, using Data::Dump. |
|
|
100 | - added -f eval support to json_xs. |
|
|
101 | |
|
|
102 | 2.29 Wed Mar 17 02:39:12 CET 2010 |
|
|
103 | - fix a memory leak when callbacks set using filter_json_object |
|
|
104 | or filter_json_single_key_object were called (great testcase |
|
|
105 | by Eric Wilhelm). |
|
|
106 | |
|
|
107 | 2.28 Thu Mar 11 20:30:46 CET 2010 |
|
|
108 | - implement our own atof function - perl's can be orders of |
|
|
109 | magnitudes slower than even the system one. on the positive |
|
|
110 | side, ours seems to be more exact in general than perl's. |
|
|
111 | (testcase provided by Tim Meadowcroft). |
|
|
112 | - clarify floating point conversion issues a bit. |
|
|
113 | - update jpsykes csrf article url. |
|
|
114 | - updated benchmark section - JSON::PP became much faster! |
|
|
115 | |
|
|
116 | 2.27 Thu Jan 7 07:35:08 CET 2010 |
|
|
117 | - support relaxed option inside the incremental parser |
|
|
118 | (testcase provided by IKEGAMI via Makamaka). |
|
|
119 | |
|
|
120 | 2.26 Sat Oct 10 03:26:19 CEST 2009 |
|
|
121 | - big integers could become truncated (based on patch |
|
|
122 | by Strobl Anton). |
|
|
123 | - output format change: indent now adds a final newline, which is |
|
|
124 | more expected and more true to the documentation. |
|
|
125 | |
|
|
126 | 2.25 Sat Aug 8 12:04:41 CEST 2009 |
|
|
127 | - the perl debugger completely breaks lvalue subs - try to work |
|
|
128 | around the issue. |
|
|
129 | - ignore RMAGICAL hashes w.r.t. CANONICAL. |
|
|
130 | - try to work around a possible char signedness issue on aix. |
|
|
131 | - require common sense. |
|
|
132 | |
|
|
133 | 2.24 Sat May 30 08:25:45 CEST 2009 |
|
|
134 | - the incremental parser did not update its parse offset |
|
|
135 | pointer correctly when parsing utf8-strings (nicely |
|
|
136 | debugged by Martin Evans). |
|
|
137 | - appending a non-utf8-string to the incremental parser |
|
|
138 | in utf8 mode failed to upgrade the string. |
|
|
139 | - wording of parse error messages has been improved. |
|
|
140 | |
|
|
141 | 2.232 Sun Feb 22 11:12:25 CET 2009 |
|
|
142 | - use an exponential algorithm to extend strings, to |
|
|
143 | help platforms with bad or abysmal==windows memory |
|
|
144 | allocater performance, at the expense of some memory |
|
|
145 | wastage (use shrink to recover this extra memory). |
|
|
146 | (nicely analysed by Dmitry Karasik). |
|
|
147 | |
|
|
148 | 2.2311 Thu Feb 19 02:12:54 CET 2009 |
|
|
149 | - add a section "JSON and ECMAscript" to explain some |
|
|
150 | incompatibilities between the two (problem was noted by |
|
|
151 | various people). |
|
|
152 | - add t/20_faihu.t. |
|
|
153 | |
|
|
154 | 2.231 Thu Nov 20 04:59:08 CET 2008 |
|
|
155 | - work around 5.10.0 magic bugs where manipulating magic values |
|
|
156 | (such as $1) would permanently damage them as perl would |
|
|
157 | ignore the magicalness, by making a full copy of the string, |
|
|
158 | reported by Dmitry Karasik. |
|
|
159 | - work around spurious warnings under older perl 5.8's. |
|
|
160 | |
|
|
161 | 2.23 Mon Sep 29 05:08:29 CEST 2008 |
|
|
162 | - fix a compilation problem when perl is not using char * as, well, |
|
|
163 | char *. |
|
|
164 | - use PL_hexdigit in favour of rolling our own. |
|
|
165 | |
|
|
166 | 2.2222 Sun Jul 20 18:49:00 CEST 2008 |
|
|
167 | - same game again, broken 5.10 finds yet another assertion |
|
|
168 | failure, and the workaround causes additional runtime warnings. |
|
|
169 | Work around the next assertion AND the warning. 5.10 seriously |
|
|
170 | needs to adjust it's attitude against working code. |
|
|
171 | |
|
|
172 | 2.222 Sat Jul 19 06:15:34 CEST 2008 |
|
|
173 | - you work around one -DDEBUGGING assertion bug in perl 5.10 |
|
|
174 | just to hit the next one. work around this one, too. |
|
|
175 | |
|
|
176 | 2.22 Tue Jul 15 13:26:51 CEST 2008 |
|
|
177 | - allow higher nesting levels in incremental parser. |
|
|
178 | - error out earlier in some cases in the incremental parser |
|
|
179 | (as suggested by Yuval Kogman). |
|
|
180 | - improve incr-parser test (Yuval Kogman). |
|
|
181 | |
|
|
182 | 2.21 Tue Jun 3 08:43:23 CEST 2008 |
|
|
183 | - (hopefully) work around a perl 5.10 bug with -DDEBUGGING. |
|
|
184 | - remove the experimental status of the incremental parser interface. |
|
|
185 | - move =encoding around again, to avoid bugs with search.cpan.org. |
|
|
186 | when can we finally have utf-8 in pod??? |
|
|
187 | - add ->incr_reset method. |
|
|
188 | |
|
|
189 | 2.2 Wed Apr 16 20:37:25 CEST 2008 |
|
|
190 | - lifted the log2 rounding restriction of max_depth and max_size. |
|
|
191 | - make booleans mutable by creating a copy instead of handing out |
|
|
192 | the same scalar (reported by pasha sadri). |
|
|
193 | - added support for incremental json parsing (still EXPERIMENTAL). |
|
|
194 | - implemented and added a json_xs command line utility that can convert |
|
|
195 | from/to a number of serialisation formats - tell me if you need more. |
|
|
196 | - implement allow_unknown/get_allow_unknown methods. |
|
|
197 | - fixed documentation of max_depth w.r.t. higher and equal. |
|
|
198 | - moved down =encoding directive a bit, too much breaks if it's the first |
|
|
199 | pod directive :/. |
|
|
200 | - removed documentation section on other modules, it became somewhat |
|
|
201 | outdated and is nowadays mostly of historical interest. |
