1 root 1.1 Revision history for Perl extension JSON::XS
2 root 1.2
3 root 1.130 TODO: booleans?
4     - ignore RMAGICAL hashes w.r.t. CANONICAL.
5 root 1.128 - try to work around a possible char signedness issue on aix.
6 root 1.129 - require common sense.
7 root 1.128
8 root 1.127 2.24 Sat May 30 08:25:45 CEST 2009
9     - the incremental parser did not update its parse offset
10     pointer correctly when parsing utf8-strings (nicely
11     debugged by Martin Evans).
12     - appending a non-utf8-string to the incremental parser
13     in utf8 mode failed to upgrade the string.
14     - wording of parse error messages has been improved.
15    
16 root 1.126 2.232 Sun Feb 22 11:12:25 CET 2009
17 root 1.125 - use an exponential algorithm to extend strings, to
18 root 1.126 help platforms with bad or abysmal==windows memory
19     allocater performance, at the expense of some memory
20 root 1.125 wastage (use shrink to recover this extra memory).
21     (nicely analysed by Dmitry Karasik).
22    
23 root 1.124 2.2311 Thu Feb 19 02:12:54 CET 2009
24 root 1.123 - add a section "JSON and ECMAscript" to explain some
25     incompatibilities between the two (problem was noted by
26     various people).
27 root 1.122 - add t/20_faihu.t.
28    
29 root 1.121 2.231 Thu Nov 20 04:59:08 CET 2008
30     - work around 5.10.0 magic bugs where manipulating magic values
31     (such as $1) would permanently damage them as perl would
32     ignore the magicalness, by making a full copy of the string,
33     reported by Dmitry Karasik.
34 root 1.125 - work around spurious warnings under older perl 5.8's.
35 root 1.121
36 root 1.120 2.23 Mon Sep 29 05:08:29 CEST 2008
37     - fix a compilation problem when perl is not using char * as, well,
38     char *.
39 root 1.119 - use PL_hexdigit in favour of rolling our own.
40    
41 root 1.118 2.2222 Sun Jul 20 18:49:00 CEST 2008
42     - same game again, broken 5.10 finds yet another assertion
43     failure, and the workaround causes additional runtime warnings.
44     Work around the next assertion AND the warning. 5.10 seriously
45     needs to adjust it's attitude against working code.
46    
47 root 1.117 2.222 Sat Jul 19 06:15:34 CEST 2008
48     - you work around one -DDEBUGGING assertion bug in perl 5.10
49     just to hit the next one. work around this one, too.
50    
51 root 1.116 2.22 Tue Jul 15 13:26:51 CEST 2008
52 root 1.115 - allow higher nesting levels in incremental parser.
53     - error out earlier in some cases in the incremental parser
54     (as suggested by Yuval Kogman).
55     - improve incr-parser test (Yuval Kogman).
56    
57 root 1.114 2.21 Tue Jun 3 08:43:23 CEST 2008
58     - (hopefully) work around a perl 5.10 bug with -DDEBUGGING.
59 root 1.112 - remove the experimental status of the incremental parser interface.
60 root 1.111 - move =encoding around again, to avoid bugs with search.cpan.org.
61     when can we finally have utf-8 in pod???
62 root 1.113 - add ->incr_reset method.
63 root 1.111
64 root 1.110 2.2 Wed Apr 16 20:37:25 CEST 2008
65 root 1.109 - lifted the log2 rounding restriction of max_depth and max_size.
66 root 1.107 - make booleans mutable by creating a copy instead of handing out
67     the same scalar (reported by pasha sadri).
68 root 1.105 - added support for incremental json parsing (still EXPERIMENTAL).
69 root 1.103 - implemented and added a json_xs command line utility that can convert
70     from/to a number of serialisation formats - tell me if you need more.
71 root 1.108 - implement allow_unknown/get_allow_unknown methods.
72 root 1.109 - fixed documentation of max_depth w.r.t. higher and equal.
73 root 1.112 - moved down =encoding directive a bit, too much breaks if it's the first
74 root 1.102 pod directive :/.
75 root 1.106 - removed documentation section on other modules, it became somewhat
76     outdated and is nowadays mostly of historical interest.
77 root 1.102
78 root 1.101 2.1 Wed Mar 19 23:23:18 CET 2008
79     - update documentation here and there: add a large section
80     about utf8/latin1/ascii flags, add a security consideration
81     and extend and clarify the JSON and YAML section.
82 root 1.98 - medium speed enhancements when encoding/decoding non-ascii chars.
83 root 1.100 - minor speedup in number encoding case.
84 root 1.92 - extend and clarify the section on incompatibilities
85     between YAML and JSON.
86 root 1.95 - switch to static inline from just inline when using gcc.
87 root 1.94 - add =encoding utf-8 to the manpage, now that perl 5.10 supports it.
88 root 1.100 - fix some issues with UV to JSON conversion of unknown impact.
89 root 1.99 - published the yahoo locals search result used in benchmarks as the
90     original url changes so comparison is impossible.
91 root 1.92
92 root 1.91 2.01 Wed Dec 5 11:40:28 CET 2007
93     - INCOMPATIBLE API CHANGE: to_json and from_json have been
94     renamed to encode_json/decode_json for JSON.pm compatibility.
95     The old functions croak and might be replaced by JSON.pm
96     comaptible versions in some later release.
97    
98 root 1.90 2.0 Tue Dec 4 11:30:46 CET 2007
99     - this is supposed to be the first version of JSON::XS
100     compatible with version 2.0+ of the JSON module.
101     Using the JSON module as frontend to JSON::XS should be
102     as fast as using JSON::XS directly, so consider using it
103     instead.
104 root 1.88 - added get_* methods for all "simple" options.
105 root 1.89 - make JSON::XS subclassable.
106 root 1.88
107 root 1.86 1.53 Tue Nov 13 23:58:33 CET 2007
108 root 1.85 - minor doc clarifications.
109     - fixed many doc typos (patch by Thomas L. Shinnick).
110    
111 root 1.84 1.52 Mon Oct 15 03:22:06 CEST 2007
112 root 1.83 - remove =encoding pod directive again, it confuses too many pod
113     parsers :/.
114    
115 root 1.82 1.51 Sat Oct 13 03:55:56 CEST 2007
116 root 1.81 - encode empty arrays/hashes in a compact way when pretty is enabled.
117 root 1.87 - apparently JSON::XS was used to find some bugs in the
118 root 1.80 JSON_checker testsuite, so add (the corrected) JSON_checker tests to
119     the testsuite.
120     - quite a bit of doc updates/extension.
121 root 1.79 - require 5.8.2, as this seems to be the first unicode-stable version.
122 root 1.78
123 root 1.77 1.5 Tue Aug 28 04:05:38 CEST 2007
124 root 1.74 - add support for tied hashes, based on ideas and testcase by
125     Marcus Holland-Moritz.
126 root 1.75 - implemented relaxed parsing mode where some extensions are being
127     accepted. generation is still JSON-only.
128 root 1.74
129     1.44 Wed Aug 22 01:02:44 CEST 2007
130 root 1.73 - very experimental process-emulation support, slowing everything down.
131     the horribly broken perl threads are still not supported - YMMV.
132    
133 root 1.72 1.43 Thu Jul 26 13:26:37 CEST 2007
134     - convert big json numbers exclusively consisting of digits to NV
135     only when there is no loss of precision, otherwise to string.
136    
137 root 1.71 1.42 Tue Jul 24 00:51:18 CEST 2007
138     - fix a crash caused by not handling missing array elements
139     (report and testcase by Jay Kuri).
140    
141 root 1.70 1.41 Tue Jul 10 18:21:44 CEST 2007
142     - fix compilation with NDEBUG (assert side-effect),
143     affects convert_blessed only.
144 root 1.69 - fix a bug in decode filters calling ENTER; SAVETMPS;
145     one time too often.
146 root 1.70 - catch a typical error in TO_JSON methods.
147 root 1.69 - antique-ised XS.xs again to work with outdated
148     C compilers (windows...).
149    
150 root 1.68 1.4 Mon Jul 2 10:06:30 CEST 2007
151 root 1.63 - add convert_blessed setting.
152 root 1.56 - encode did not catch all blessed objects, encoding their
153     contents in most cases. This has been fixed by introducing
154     the allow_blessed setting.
155 root 1.65 - added filter_json_object and filter_json_single_key_object
156     settings that specify a callback to be called when
157 root 1.67 all/specific json objects are encountered.
158 root 1.59 - assume that most object keys are simple ascii words and
159     optimise this case, penalising the general case. This can
160     speed up decoding by 30% in typical cases and gives
161     a smaller and faster perl hash.
162 root 1.58 - implemented simpleminded, optional resource size checking
163     in decode_json.
164 root 1.61 - remove objToJson/jsonToObj aliases, as the next version
165     of JSON will not have them either.
166 root 1.62 - bit the bullet and converted the very simple json object
167     into a more complex one.
168 root 1.64 - work around a bug where perl wrongly claims an integer
169     is not an integer.
170 root 1.65 - unbundle JSON::XS::Boolean into own pm file so Storable
171     and similar modules can resolve the overloading when thawing.
172 root 1.56
173 root 1.55 1.3 Sun Jun 24 01:55:02 CEST 2007
174 root 1.54 - make JSON::XS::true and false special overloaded objects
175     and return those instead of 1 and 0 for those json atoms
176     (JSON::PP compatibility is NOT achieved yet).
177     - add JSON::XS::is_bool predicate to test for those special
178     values.
179 root 1.52 - add a reference to
180     http://jpsykes.com/47/practical-csrf-and-json-security.
181 root 1.60 - removed require 5.8.8 again, it is just not very expert-friendly.
182     Also try to be more compatible with slightly older versions,
183 root 1.54 which are not recommended (because they are buggy).
184 root 1.52
185 root 1.51 1.24 Mon Jun 11 05:40:49 CEST 2007
186 root 1.49 - added informative section on JSON-as-YAML.
187 root 1.51 - get rid of some c99-isms again.
188 root 1.50 - localise dec->cur in decode_str, speeding up
189     string decoding considerably (>15% on my amd64 + gcc).
190     - increased SHORT_STRING_LEN to 16kb: stack space is
191     usually plenty, and this actually saves memory
192 root 1.51 when !shrinking as short strings will fit perfectly.
193 root 1.49
194 root 1.47 1.23 Wed Jun 6 20:13:06 CEST 2007
195 root 1.46 - greatly improved small integer encoding and decoding speed.
196     - implement a number of µ-optimisations.
197 root 1.47 - updated benchmarks.
198 root 1.46
199 root 1.45 1.22 Thu May 24 00:07:25 CEST 2007
200 root 1.42 - require 5.8.8 explicitly as older perls do not seem to offer
201     the required macros.
202 root 1.43 - possibly made it compile on so-called C compilers by microsoft.
203 root 1.42
204 root 1.41 1.21 Wed May 9 18:40:32 CEST 2007
205 root 1.47 - character offset reported for trailing garbage was random.
206 root 1.41
207 root 1.40 1.2 Wed May 9 18:35:01 CEST 2007
208     - decode did not work with magical scalars (doh!).
209 root 1.38 - added latin1 flag to produce JSON texts in the latin1 subset
210     of unicode.
211 root 1.39 - flag trailing garbage as error.
212     - new decode_prefix method that returns the number
213     of characters consumed by a decode.
214 root 1.40 - max octets/char in perls UTF-X is actually 13, not 11,
215     as pointed out by Glenn Linderman.
216     - fixed typoe reported by YAMASHINA Hio.
217 root 1.34
218 root 1.32 1.11 Mon Apr 9 07:05:49 CEST 2007
219     - properly 0-terminate sv's returned by encode to help
220     C libraries that expect that 0 to be there.
221 root 1.31 - partially "port" JSON from C to microsofts fucking broken
222     pseudo-C. They should be burned to the ground for pissing
223     on standards. And I should be stoned for even trying to
224 root 1.32 support this filthy excuse for a c compiler.
225 root 1.6
226 root 1.30 1.1 Wed Apr 4 01:45:00 CEST 2007
227 root 1.28 - clarify documentation (pointed out by Quinn Weaver).
228 root 1.29 - decode_utf8 sometimes did not correctly flag errors,
229     leading to segfaults.
230 root 1.30 - further reduced default nesting depth to 512 due to the test
231     failure by that anonymous "chris" whose e-mail address seems
232     to be impossible to get. Tests on other freebsd systems indicate
233     that this is likely a problem in his/her configuration and not this
234     module.
235     - renamed json => JSON in error messages.
236     - corrected the character offset in some error messages.
237 root 1.28
238 root 1.27 1.01 Sat Mar 31 16:15:40 CEST 2007
239     - do not segfault when from_json/decode gets passed
240     a non-string object (reported by Florian Ragwitz).
241     This has no effect on normal operation.
242    
243 root 1.25 1.0 Thu Mar 29 04:43:34 CEST 2007
244     - the long awaited (by me) 1.0 version.
245     - add \0 (JSON::XS::false) and \1 (JSON::XS::true) mappings to JSON
246     true and false.
247 root 1.24 - add some more notes to shrink, as suggested by Alex Efros.
248 root 1.25 - improve testsuite.
249 root 1.26 - halve the default nesting depth limit, to hopefully make it
250 root 1.25 work on Freebsd (unfortunately, the cpan tester did not
251     send me his report, so I cannot ask about the stack limit on fbsd).
252 root 1.24
253 root 1.23 0.8 Mon Mar 26 00:10:48 CEST 2007
254 root 1.21 - fix a memleak when decoding hashes.
255 root 1.20 - export jsonToBj and objToJson as aliases
256     to to_json and from_json, to reduce incompatibilities
257     between JSON/JSON::PC and JSON::XS. (experimental).
258 root 1.21 - implement a maximum nesting depth for both en- and de-coding.
259     - added a security considerations sections.
260 root 1.20
261 root 1.19 0.7 Sun Mar 25 01:46:30 CET 2007
262 root 1.16 - code cleanup.
263     - fix a memory overflow bug when indenting.
264     - pretty-printing now up to 15% faster.
265     - improve decoding speed of strings by
266     up to 50% by specialcasing short strings.
267     - further decoding speedups for strings using
268     lots of \u escapes.
269 root 1.17 - improve utf8 decoding speed for U+80 .. U+7FF.
270 root 1.16
271 root 1.15 0.5 Sat Mar 24 20:41:51 CET 2007
272 root 1.14 - added the UTF-16 encoding example hinted at in previous
273     versions.
274     - minor documentation fixes.
275 root 1.15 - fix a bug in and optimise canonicalising fastpath
276     (reported by Craig Manley).
277     - remove a subtest that breaks with bleadperl (reported
278     by Andreas König).
279 root 1.14
280 root 1.13 0.31 Sat Mar 24 02:14:34 CET 2007
281 root 1.12 - documentation updates.
282 root 1.13 - do some casting to hopefully fix Andreas' problem.
283     - nuke bogus json rpc stuff.
284 root 1.12
285 root 1.11 0.3 Fri Mar 23 19:33:21 CET 2007
286 root 1.5 - remove spurious PApp::Util reference (John McNamara).
287     - adapted lots of tests from other json modules
288     (idea by Chris Carline).
289 root 1.9 - documented mapping from json to perl and vice versa.
290 root 1.11 - improved the documentation by adding more examples.
291 root 1.5 - added short escaping forms, reducing the created
292     json texts a bit.
293     - added shrink flag.
294     - when flag methods are called without enable argument
295     they will by default enable their flag.
296     - considerably improved string encoding speed (at least
297     with gcc 4).
298 root 1.7 - added a test that covers lots of different characters.
299     - clarified some error messages.
300     - error messages now use correct character offset
301     with F_UTF8.
302 root 1.8 - improve the "no bytes" and "no warnings" hacks in
303     case the called functions do... stuff.
304 root 1.9 - croak when encoding to ascii and an out-of-range
305     (non-unicode) codepoint is encountered.
306 root 1.4
307 root 1.3 0.2 Fri Mar 23 00:23:34 CET 2007
308 root 1.109 - the "could not sleep without debugging release".
309 root 1.3 it should basically work now, with many bugs as
310     no production tests have been run yet.
311     - added more testcases.
312     - the expected shitload of bugfixes.
313     - handle utf8 flag correctly in decode.
314     - fix segfault in decoder.
315     - utf8n_to_uvuni sets retlen to -1, but retlen is an
316     unsigned types (argh).
317     - fix decoding of utf-8 strings.
318     - improved error diagnostics.
319     - fix decoding of 'null'.
320     - fix parsing of empty array/hashes
321     - silence warnings when we prepare the croak message.
322    
323 root 1.2 0.1 Thu Mar 22 22:13:43 CET 2007
324     - first release, very untested, basically just to claim
325     the namespace.
326 root 1.1
327     0.01 Thu Mar 22 06:08:12 CET 2007
328     - original version; cloned from Convert-Scalar
329
