9 | New features | |
10 | ------------ | |
85ed501a EH |
11 | * json_patch: add first implementation only with patch application |
12 | * Add --disable-static and --disable-dynamic options to the cmake-configure script. | |
13 | * Add -DBUILD_APPS=NO option to disable app build | |
14 | * Minimum cmake version is now 3.9 | |
9749b0cb EH |
15 | |
16 | Significant changes and bug fixes | |
17 | --------------------------------- | |
18 | * When serializing with JSON_C_TO_STRING_PRETTY set, keep the opening and | |
19 | closing curly or square braces on same line for empty objects or arrays. | |
253a5fa9 EH |
20 | * Disable locale handling when targeting a uClibc system due to problems |
21 | with its duplocale() function. | |
d6f46ae1 EH |
22 | * When parsing with JSON_TOKENER_STRICT set, integer overflow/underflow |
23 | now result in a json_tokener_error_parse_number. Without that flag | |
24 | values are capped at INT64_MIN/UINT64_MAX. | |
85ed501a EH |
25 | * Fix memory leak with emtpy strings in json_object_set_string |
26 | * json_object_from_fd_ex: fail if file is too large (>=INT_MAX bytes) | |
27 | * Add back json_number_chars, but only because it's part of the public API. | |
28 | * Entirely drop mode bits from open(O_RDONLY) to avoid warnings on certain | |
29 | platforms. | |
30 | * Specify dependent libraries, including -lbsd, in a more consistent way so | |
31 | linking against a static json-c works better | |
32 | * Fix a variety of build problems and add & improve tests | |
33 | * Update RFC reference to https://www.rfc-editor.org/rfc/rfc8259 | |

7d303478 EH |
48 | New features |
49 | ------------ | |
50 | * The 0.16 release introduces no new features | |
51 | ||
52 | Build changes | |
53 | ------------- | |
54 | * Add a DISABLE_EXTRA_LIBS option to skip using libbsd | |
55 | * Add a DISABLE_JSON_POINTER option to skip compiling in json_pointer support. | |
56 | ||
57 | Significant changes and bug fixes | |
58 | --------------------------------- | |
59 | * Cap string length at INT_MAX to avoid various issues with very long strings. | |
60 | * json_object_deep_copy: fix deep copy of strings containing '\0' | |
61 | * Fix read past end of buffer in the "json_parse" command | |
62 | * Avoid out of memory accesses in the locally provided vasprintf() function | |
63 | (for those platforms that use it) | |
64 | * Handle allocation failure in json_tokener_new_ex | |
65 | * Fix use-after-free in json_tokener_new_ex() in the event of printbuf_new() returning NULL | |
66 | * printbuf_memset(): set gaps to zero - areas within the print buffer which | |
67 | have not been initialized by using printbuf_memset | |
68 | * printbuf: return -1 on invalid arguments (len < 0 or total buffer > INT_MAX) | |
69 | * sprintbuf(): propagate printbuf_memappend errors back to the caller | |
70 | ||
71 | Optimizations | |
72 | -------------- | |
73 | * Speed up parsing by replacing ctype functions with simplified, faster | |
74 | non-locale-sensitive ones in json_tokener and json_object_to_json_string. | |
75 | * Neither vertical tab nor formfeed are considered whitespace per the JSON spec | |
76 | * json_object: speed up creation of objects, calloc() -> malloc() + set fields | |
77 | * Avoid needless extra strlen() call in json_c_shallow_copy_default() and | |
78 | json_object_equal() when the object is known to be a json_type_string. | |
79 | ||
80 | Other changes | |
81 | ------------- | |
82 | * Validate size arguments in arraylist functions. | |
83 | * Use getrandom() if available; with GRND_NONBLOCK to allow use of json-c | |
84 | very early during boot, such as part of cryptsetup. | |
85 | * Use arc4random() if it's available. | |
86 | * random_seed: on error, continue to next method instead of exiting the process | |
87 | * Close file when unable to read from /dev/urandom in get_dev_random_seed() | |

95 | -------------------------------- | |
024e835f EH |
96 | * Deprecate `array_list_new()` in favor of `array_list_new2()` |
97 | * Remove the THIS_FUNCTION_IS_DEPRECATED define. | |

2babb5b7 | 99 | |
024e835f EH |
100 | New features |
101 | ------------ | |
102 | * Add a `JSON_TOKENER_ALLOW_TRAILING_CHARS` flag to allow multiple objects | |
103 | to be parsed even when `JSON_TOKENER_STRICT` is set. | |
104 | * Add `json_object_new_array_ext(int)` and `array_list_new_2(int)` to allow | |
105 | arrays to be allocated with the exact size needed, when known. | |
106 | * Add `json_object_array_shrink()` (and `array_list_shrink()`) and use it in | |
107 | json_tokener to minimize the amount of memory used. | |
108 | * Add a json_parse binary, for use in testing changes (not installed, but | |
109 | available in the apps directory). | |
110 | ||
111 | Build changes | |
112 | ------------- | |
113 | * #639/#621 - Add symbol versions to all exported symbols | |
114 | * #508/#634 - Always enable -fPIC to allow use of the json-c static library in | |
115 | other libraries | |
116 | * Build both static and shared libraries at the same time. | |
117 | * #626 - Restore compatibility with cmake 2.8 | |
118 | * #471 - Always create directories with mode 0755, regardless of umask. | |
119 | * #606/#604 - Improve support for OSes like AIX and IBM i, as well as for | |
120 | MINGW32 and old versions of MSVC | |
121 | * #451/#617 - Add a DISABLE_THREAD_LOCAL_STORAGE cmake option to disable | |
122 | the use of thread-local storage. | |

124 | Significant changes and bug fixes | |
125 | --------------------------------- | |
02fe2e0c EH |
126 | * Split the internal json_object structure into several sub-types, one for |
127 | each json_type (json_object_object, json_object_string, etc...). | |
128 | This improves memory usage and speed, with the benchmark under | |
129 | bench/ report 5.8% faster test time and 6%(max RSS)-12%(peak heap) | |
130 | less memory usage. | |
131 | Memory used just for json_object structures decreased 27%, so use cases | |
132 | with fewer arrays and/or strings would benefit more. | |
e26a1195 EH |
133 | * Minimize memory usage in array handling in json_tokener by shrinking |
134 | arrays to the exact number of elements parsed. On bench/ benchmark: | |
135 | 9% faster test time, 39%(max RSS)-50%(peak heap) less memory usage. | |
136 | Add json_object_array_shrink() and array_list_shrink() functions. | |
024e835f | 137 | * #616 - Parsing of surrogate pairs in unicode escapes now properly handles |
a68566bf | 138 | incremental parsing. |
6eac6986 EH |
139 | * Fix incremental parsing of numbers, especially those with exponents, e.g. |
140 | so parsing "[0", "e+", "-]" now properly returns an error. | |
141 | Strict mode now rejects missing exponents ("0e"). | |
f23486a3 EH |
142 | * Successfully return number objects at the top level even when they are |
143 | followed by a "-", "." or "e". This makes parsing things like "123-45" | |
144 | behave consistently with things like "123xyz". | |
f6f76f94 | 145 | |
024e835f EH |
146 | Other changes |
147 | ------------- | |
148 | * #589 - Detect broken RDRAND during initialization; also, fix segfault | |
149 | in the CPUID check. | |
150 | * #592 - Fix integer overflows to prevert out of bounds write on large input. | |
3bb54f97 | 151 | * Protect against division by zero in linkhash, when created with zero size. |
024e835f EH |
152 | * #602 - Fix json_parse_uint64() internal error checking, leaving the retval |
153 | untouched in more failure cases. | |

177 | * With the addition of json_tokener_get_parse_end(), access to internal fields of json_tokener, as well as use of many other symbols and types in json_tokener.h, is deprecated now. | |
178 | * The use of Android.configure.mk to build for Android no longer works, and it is unknown how (or if) the new cmake-based build machinery can be used. | |
179 | * Reports of success, or pull requests to correct issues are welcome. | |
180 | ||
181 | ## Notable improvements and new features | |
182 | ||
183 | ### Builds and documentation | |
184 | * Build machinery has been switched to CMake. See README.md for details about how to build. | |
185 | * TL;DR: `mkdir build ; cd build ; cmake -DCMAKE_INSTALL_PREFIX=/some/path ../json-c ; make all test install` | |
186 | * To ease the transition, there is a `cmake-configure` wrapper that emulates the old autoconf-based configure script. | |
187 | * This has enabled improvements to the build on Windows system; also all public functions have been fixed to be properly exported. For best results, use Visual Studio 2015 or newer. | |
188 | * The json-c style guide has been updated to specify the use of clang-format, and all code has been reformatted. | |
189 | * Since many lines of code have trivial changes now, when using git blame, be sure to specify -w | |
190 | * Numerous improvements have been made to the documentation including function effects on refcounts, when passing a NULL is safe, and so on. | |
191 | ||
192 | ### json_tokener changes | |
193 | * Added a json_tokener_get_parse_end() function to replace direct access of tok->char_offset. | |
194 | * The char_offset field, and the rest of the json_tokener structure remain exposed for now, but expect a future release to hide it like is done with json_object_private.h | |
195 | * json_tokener_parse_ex() now accepts a new JSON_TOKENER_VALIDATE_UTF8 flag to validate that input is UTF8. | |
196 | * If validation fails, json_tokener_get_error(tok) will return json_tokener_error_parse_utf8_string (see enum json_tokener_error). | |
197 | ||
198 | ### Other changes and additions | |
199 | * Add support for unsigned 64-bit integers, uint64_t, to gain one extra bit of magnitude for positive ints. | |
200 | * json_tokener will now parse values up to UINT64_MAX (18446744073709551615) | |
201 | * Existing methods returning int32_t or int64_t will cap out-of-range values at INT32_MAX or INT64_MAX, preserving existing behavior. | |
202 | * The implementation includes the possibility of easily extending this to larger sizes in the future. | |
203 | * A total of 7 new functions were added: | |
204 | * json_object_get_uint64 ( struct json_object const* jso ) | |
205 | * json_object_new_uint64 ( uint64_t i ) | |
206 | * json_object_set_uint64 ( struct json_object* jso, uint64_t new_value ) | |
207 | * json_parse_uint64 ( char const* buf, uint64_t* retval ) | |
208 | * See description of uint64 support, above. | |
209 | * json_tokener_get_parse_end ( struct json_tokener* tok ) | |
210 | * See details under "json_tokener changes", above. | |
211 | * json_object_from_fd_ex ( int fd, int in_depth ) | |
212 | * Allows the max nesting depth to be specified. | |
213 | * json_object_new_null ( ) | |
214 | * Simply returns NULL. Its use is not recommended. | |
215 | * The size of struct json_object has decreased from 96 bytes to 88 bytes. | |
216 | ||
217 | ### Testing | |
218 | * Many updates were made to test cases, increasing code coverage. | |
219 | * There is now a quick way (JSONC_TEST_TRACE=1) to turn on shell tracing in tests. | |
220 | * To run tests, use `make test`; the old "check" target no longer exists. | |
221 | ||
222 | ## Significant bug fixes | |
223 | For the full list of issues and pull requests since the previous release, please see issues_closed_for_0.14.md | |
224 | ||
225 | * [Issue #389](https://github.com/json-c/json-c/issues/389): Add an assert to explicitly crash when _ref_count is corrupted, instead of a later "double free" error. | |
226 | * [Issue #407](https://github.com/json-c/json-c/issues/407): fix incorrect casts in calls to ctype functions (isdigit and isspace) so we don't crash when asserts are enabled on certain platforms and characters > 128 are parsed. | |
227 | * [Issue #418](https://github.com/json-c/json-c/issues/418): Fix docs for json_util_from_fd and json_util_from_file to say that they return NULL on failures. | |
228 | * [Issue #422](https://github.com/json-c/json-c/issues/422): json_object.c:set errno in json_object_get_double() when called on a json_type_string object with bad content. | |
229 | * [Issue #453](https://github.com/json-c/json-c/issues/453): Fixed misalignment in JSON serialization when JSON_C_TO_STRING_SPACED and JSON_C_TO_STRING_PRETTY are used together. | |
230 | * [Issue #463](https://github.com/json-c/json-c/issues/463): fix newlocale() call to use LC_NUMERIC_MASK instead of LC_NUMERIC, and remove incorrect comment. | |
231 | * [Issue #486](https://github.com/json-c/json-c/issues/486): append a missing ".0" to negative double values to ensure they are serialized as floating point numbers. | |
232 | * [Issue #488](https://github.com/json-c/json-c/issues/488): use JSON_EXPORT on functions so they are properly exported on Windows. | |
233 | * [Issue #539](https://github.com/json-c/json-c/issues/539): use an internal-only serializer function in json_object_new_double_s() to avoid potential conflicts with user code that uses the json_object_userdata_to_json_string serializer. | |

252 | ================================= | |
253 | ||
254 | This release, being three and a half years after the 0.12 branch (f84d9c), | |
255 | has quite a number of changes included. The following is a sampling of | |
256 | the most significant ones. | |
257 | ||
258 | Since the 0.12 release, 250 issues and pull requests have been closed. | |
259 | See issues_closed_for_0.13.md for a complete list. | |

262 | Deprecated and removed features: | |
263 | -------------------------------- | |
264 | * All internal use of bits.h has been eliminated. The file will be removed. | |
259d5078 | 265 | Do not use: hexdigit(), error_ptr(), error_descrition() and it_error() |
b34d26ff EH |
266 | * lh_abort() is deprecated. It will be removed. |
267 | ||
268 | Behavior changes: | |
269 | ----------------- | |
270 | * Tighten the number parsing algorithm to raise errors instead of truncating | |
271 | the results. For example 12.3.4 or 2015-01-15, which now return null. | |
272 | See commit 99d8fc | |
273 | ||
274 | * Use size_t for array length and size. Platforms where sizeof(size_t) != sizeof(int) may not be backwards compatible | |
275 | See commits 45c56b, 92e9a5 and others. | |
276 | ||
3bb54f97 | 277 | * Check for failure when allocating memory, returning NULL and errno=ENOMEM. |
b34d26ff EH |
278 | See commit 2149a04. |
279 | ||
280 | * Change json_object_object_add() return type from void to int, and will return -1 on failures, instead of exiting. (Note: this is not an ABI change) | |
281 | ||
282 | New features: | |
283 | ------------- | |
284 | * We're aiming to follow RFC 7159 now. | |
285 | ||
286 | * Add a couple of additional option to json_object_to_json_string_ext: | |
287 | JSON_C_TO_STRING_PRETTY_TAB | |
288 | JSON_C_TO_STRING_NOSLASHESCAPE | |
289 | ||
290 | * Add a json_object_object_add_ex() function to allow for performance | |
291 | improvements when certain constraints are known to be true. | |
292 | ||
293 | * Make serialization format of doubles configurable, in two different ways: | |
294 | Call json_object_set_serializer with json_object_double_to_json_string and a custom | |
295 | format on each double object, or | |
296 | Call json_c_set_serialization_double_format() to set a global or thread-wide format. | |
297 | ||
298 | * Add utility function for comparing json_objects - json_object_equal() | |
299 | ||
300 | * Add a way to copy entire object trees: json_object_deep_copy() | |
301 | * Add json_object_set_<type> function to modify the value of existing json_object's | |
302 | without the need to recreate them. Also add a json_object_int_inc function to | |
303 | adjust an int's value. | |
304 | * Add support for JSON pointer, RFC 6901. See json_pointer.h | |
305 | * Add a json_util_get_last_err() function to retrieve the string describing the | |
306 | cause of errors, instead of printing to stderr. | |
307 | * Add perllike hash function for strings, and json_global_set_string_hash() 8f8d03d | |
308 | * Add a json_c_visit() function to provide a way to iterate over a tree of json-c objects. | |
309 | ||
310 | Notable bug fixes and other improvements: | |
311 | ----------------------------------------- | |
312 | * Make reference increment and decrement atomic to allow passing json objects between threads. | |
313 | * Fix json_object_object_foreach to avoid uninitialized variable warnings. | |
314 | * Improve performance by removing unneeded data items from hashtable code and reducing duplicate hash computation. | |
315 | * Improve performance by storing small strings inside json_object | |
316 | * Improve performance of json_object_to_json_string by removing variadic printf. commit 9ff0f49 | |
317 | * Issue #371: fix parsing of "-Infinity", and avoid needlessly copying the input when doing so. | |
318 | * Fix stack buffer overflow in json_object_double_to_json_string_format() - commit 2c2deb87 | |
319 | * Fix various potential null ptr deref and int32 overflows | |
320 | * Issue #332: fix a long-standing bug in array_list_put_idx() where it would attempt to free previously free'd entries due to not checking the current array length. | |
321 | * Issue #195: use uselocale() instead of setlocale() in json_tokener to behave better in threaded environments. | |
322 | * Issue #275: fix out of bounds read when handling unicode surrogate pairs. | |
323 | * Ensure doubles that happen to be a whole number are emitted with ".0" - commit ca7a19 | |
324 | * PR#331: for Visual Studio, use a snprintf/vsnprintf wrapper that ensures the string is terminated. | |
325 | * Fix double to int cast overflow in json_object_get_int64. | |
326 | * Clamp double to int32 when narrowing in json_object_get_int. | |
327 | * Use strtoll() to parse ints - instead of sscanf | |
328 | * Miscellaneous smaller changes, including removing unused variables, fixing warning | |
329 | about uninitialized variables adding const qualifiers, reformatting code, etc... | |
330 | ||
331 | Build changes: | |
332 | -------------- | |
333 | * Add Appveyor and Travis build support | |
334 | * Switch to using CMake when building on Windows with Visual Studio. | |
335 | A dynamic .dll is generated instead of a .lib | |
336 | config.h is now generated, config.h.win32 should no longer be manually copied | |
337 | * Add support for MacOS through CMake too. | |
338 | * Enable silent build by default | |
339 | * Link against libm when needed | |
340 | * Add support for building with AddressSanitizer | |
341 | * Add support for building with Clang | |
342 | * Add a --enable-threading configure option, and only use the (slower) __sync_add_and_fetch()/__sync_sub_and_fetch() function when it is specified. | |

b34d26ff | 390 | ====== |
a42caac8 EH |
391 | |
392 | * Minimal changes to address compile issues. | |
393 | ||
f84d9c55 | 394 | 0.12 |
b34d26ff | 395 | ==== |
f84d9c55 EH |
396 | |
397 | * Address security issues: | |
398 | * CVE-2013-6371: hash collision denial of service | |
399 | * CVE-2013-6370: buffer overflow if size_t is larger than int | |
400 | ||
401 | * Avoid potential overflow in json_object_get_double | |
402 | ||
403 | * Eliminate the mc_abort() function and MC_ABORT macro. | |
404 | ||
405 | * Make the json_tokener_errors array local. It has been deprecated for | |
406 | a while, and json_tokener_error_desc() should be used instead. | |
407 | ||
259d5078 | 408 | * change the floating point output format to %.17g so values with |
f84d9c55 EH |
409 | more than 6 digits show up in the output. |
410 | ||
411 | * Remove the old libjson.so name compatibility support. The library is | |
259d5078 | 412 | only created as libjson-c.so now and headers are only installed |
f84d9c55 EH |
413 | into the ${prefix}/json-c directory. |
414 | ||
415 | * When supported by the linker, add the -Bsymbolic-functions flag. | |
416 | ||
417 | * Various changes to fix the build on MSVC. | |
418 | ||
419 | * Make strict mode more strict: | |
420 | * number must not start with 0 | |
421 | * no single-quote strings | |
422 | * no comments | |
423 | * trailing char not allowed | |
424 | * only allow lowercase literals | |
4207147c | 425 | |
51993c28 EH |
426 | * Added a json_object_new_double_s() convenience function to allow |
427 | an exact string representation of a double to be specified when | |
428 | creating the object and use it in json_tokener_parse_ex() so | |
429 | a re-serialized object more exactly matches the input. | |
4207147c | 430 | |
f84d9c55 EH |
431 | * Add support NaN and Infinity |

b34d26ff | 435 | ==== |
8ce53f9d EH |
436 | |
437 | * IMPORTANT: the name of the library has changed to libjson-c.so and | |
438 | the header files are now in include/json-c. | |
439 | The pkgconfig name has also changed from json to json-c. | |
440 | You should change your build to use appropriate -I and -l options. | |
441 | A compatibility shim is in place so builds using the old name will | |
442 | continue to work, but that will be removed in the next release. | |
197cb1d1 RC |
443 | * Maximum recursion depth is now a runtime option. |
444 | json_tokener_new() is provided for compatibility. | |
445 | json_tokener_new_ex(depth) | |
eee744cd EH |
446 | * Include json_object_iterator.h in the installed headers. |
447 | * Add support for building on Android. | |
448 | * Rewrite json_object_object_add to replace just the value if the key already exists so keys remain valid. | |
449 | * Make it safe to delete keys while iterating with the json_object_object_foreach macro. | |
450 | * Add a json_set_serializer() function to allow the string output of a json_object to be customized. | |
451 | * Make float parsing locale independent. | |
452 | * Add a json_tokener_set_flags() function and a JSON_TOKENER_STRICT flag. | |
453 | * Enable -Werror when building. | |
454 | * speed improvements to parsing 64-bit integers on systems with working sscanf | |
455 | * Add a json_object_object_length function. | |
456 | * Fix a bug (buffer overrun) when expanding arrays to more than 64 entries. | |
8ce53f9d | 457 | |
f5dd43a9 | 458 | 0.10 |
b34d26ff | 459 | ==== |
1abaaee6 EH |
460 | |
461 | * Add a json_object_to_json_string_ext() function to allow output to be | |
462 | formatted in a more human readable form. | |
463 | * Add json_object_object_get_ex(), a NULL-safe get object method, to be able | |
464 | to distinguish between a key not present and the value being NULL. | |
465 | * Add an alternative iterator implementation, see json_object_iterator.h | |
466 | * Make json_object_iter public to enable external use of the | |
467 | json_object_object_foreachC macro. | |
3bb54f97 | 468 | * Add a printbuf_memset() function to provide an efficient way to set and |
1abaaee6 EH |
469 | append things like whitespace indentation. |
470 | * Adjust json_object_is_type and json_object_get_type so they return | |
471 | json_type_null for NULL objects and handle NULL passed to | |
472 | json_objct_object_get(). | |
473 | * Rename boolean type to json_bool. | |
474 | * Fix various compile issues for Visual Studio and MinGW. | |
475 | * Allow json_tokener_parse_ex() to be re-used to parse multiple object. | |
476 | Also, fix some parsing issues with capitalized hexadecimal numbers and | |
477 | number in E notation. | |
259d5078 | 478 | * Add json_tokener_get_error() and json_tokener_error_desc() to better |
1abaaee6 EH |
479 | encapsulate the process of retrieving errors while parsing. |
480 | * Various improvements to the documentation of many functions. | |
481 | * Add new json_object_array_sort() function. | |
20707f4e EH |
482 | * Fix a bug in json_object_get_int(), which would incorrectly return 0 |
483 | when called on a string type object. | |
484 | Eric Haszlakiewicz | |
485 | * Add a json_type_to_name() function. | |
486 | Eric Haszlakiewicz | |
487 | * Add a json_tokener_parse_verbose() function. | |
