JSON-C implements a reference counting object model that allows you to easily construct JSON objects in C, output them as JSON formatted strings and parse JSON formatted strings back into the C representation of JSON objects. This package includes the json-c documentation.
MIT
* Wed Dec 06 2023 Guillaume GARDET <guillaume.gardet@opensuse.org>
- Drop unneeded -DCMAKE_C_FLAGS=-std=gnu99 to use distro CFLAGS
* Fri Nov 03 2023 Paolo Stivanin <info@paolostivanin.com>
- Update to 0.17:
+ New features:
* json_patch: add first implementation only with patch application
* Add --disable-static and --disable-dynamic options to the cmake-configure script.
* Add -DBUILD_APPS=NO option to disable app build
* Minimum cmake version is now 3.9
+ Significant changes and bug fixes:
* When serializing with JSON_C_TO_STRING_PRETTY set, keep the opening and
closing curly or square braces on same line for empty objects or arrays.
* Disable locale handling when targeting a uClibc system due to problems
with its duplocale() function.
* When parsing with JSON_TOKENER_STRICT set, integer overflow/underflow
now result in a json_tokener_error_parse_number. Without that flag
values are capped at INT64_MIN/UINT64_MAX.
* Fix memory leak with emtpy strings in json_object_set_string
* json_object_from_fd_ex: fail if file is too large (>=INT_MAX bytes)
* Add back json_number_chars, but only because it's part of the public API.
* Entirely drop mode bits from open(O_RDONLY) to avoid warnings on certain
platforms.
* Specify dependent libraries, including -lbsd, in a more consistent way so
linking against a static json-c works better
* Fix a variety of build problems and add & improve tests
* Update RFC reference to https://www.rfc-editor.org/rfc/rfc8259
- Remove deprecated suse_version checks
* Wed Apr 20 2022 Paolo Stivanin <info@paolostivanin.com>
- Update to 0.16:
+ Deprecated and removed features:
* JSON_C_OBJECT_KEY_IS_CONSTANT is deprecated in favor of
JSON_C_OBJECT_ADD_CONSTANT_KEY
* Direct access to lh_table and lh_entry structure members is deprecated.
Use access functions instead, lh_table_head(), lh_entry_next(), etc...
* Drop REFCOUNT_DEBUG code.
+ Changes and bug fixes
* Cap string length at INT_MAX to avoid various issues with very long strings.
* json_object_deep_copy: fix deep copy of strings containing '\0'
* Fix read past end of buffer in the "json_parse" command
* Avoid out of memory accesses in the locally provided vasprintf() function
(for those platforms that use it)
* Handle allocation failure in json_tokener_new_ex
* Fix use-after-free in json_tokener_new_ex() in the event of printbuf_new() returning NULL
* printbuf_memset(): set gaps to zero - areas within the print buffer which
have not been initialized by using printbuf_memset
* printbuf: return -1 on invalid arguments (len < 0 or total buffer > INT_MAX)
* sprintbuf(): propagate printbuf_memappend errors back to the caller
* Validate size arguments in arraylist functions.
* Use getrandom() if available; with GRND_NONBLOCK to allow use of json-c
very early during boot, such as part of cryptsetup.
* Use arc4random() if it's available.
* random_seed: on error, continue to next method instead of exiting the process
* Close file when unable to read from /dev/urandom in get_dev_random_seed()
* Speed up parsing by replacing ctype functions with simplified, faster
non-locale-sensitive ones in json_tokener and json_object_to_json_string.
* Neither vertical tab nor formfeed are considered whitespace per the JSON spec
* json_object: speed up creation of objects, calloc() -> malloc() + set fields
* Avoid needless extra strlen() call in json_c_shallow_copy_default() and
json_object_equal() when the object is known to be a json_type_string.
* Wed May 19 2021 Fridrich Strba <fstrba@suse.com>
- Add -std=gnu99 to fix build with some gcc versions
* Mon Aug 17 2020 Dirk Mueller <dmueller@suse.com>
- update to 0.15:
* Deprecate `array_list_new()` in favor of `array_list_new2()`
* Remove the THIS_FUNCTION_IS_DEPRECATED define.
* Remove config.h.win32
* Add a `JSON_TOKENER_ALLOW_TRAILING_CHARS` flag to allow multiple objects
to be parsed even when `JSON_TOKENER_STRICT` is set.
* Add `json_object_new_array_ext(int)` and `array_list_new_2(int)` to allow
arrays to be allocated with the exact size needed, when known.
* Add `json_object_array_shrink()` (and `array_list_shrink()`) and use it in
json_tokener to minimize the amount of memory used.
* Add a json_parse binary, for use in testing changes (not installed, but
available in the apps directory).
* Split the internal json_object structure into several sub-types, one for
each json_type (json_object_object, json_object_string, etc...).
This improves memory usage and speed, with the benchmark under
bench/ report 5.8% faster test time and 6%(max RSS)-12%(peak heap)
less memory usage.
Memory used just for json_object structures decreased 27%, so use cases
with fewer arrays and/or strings would benefit more.
* Minimize memory usage in array handling in json_tokener by shrinking
arrays to the exact number of elements parsed. On bench/ benchmark:
9% faster test time, 39%(max RSS)-50%(peak heap) less memory usage.
Add json_object_array_shrink() and array_list_shrink() functions.
* #616 - Parsing of surrogate pairs in unicode escapes now properly handles
incremental parsing.
* Fix incremental parsing of numbers, especially those with exponents, e.g.
so parsing "[0", "e+", "-]" now properly returns an error.
Strict mode now rejects missing exponents ("0e").
* Successfully return number objects at the top level even when they are
followed by a "-", "." or "e". This makes parsing things like "123-45"
behave consistently with things like "123xyz".
* #589 - Detect broken RDRAND during initialization; also, fix segfault
in the CPUID check.
* #592 - Fix integer overflows to prevert out of bounds write on large input.
* Protect against division by zero in linkhash, when creaed with zero size.
* #602 - Fix json_parse_uint64() internal error checking, leaving the retval
untouched in more failure cases.
* #614 - Prevent truncation when custom double formatters insert extra \0's
- remove 0001-Detect-broken-RDRAND-during-initialization.patch (upstream)
* Wed Jun 17 2020 Dan Čermák <dcermak@suse.com>
- Add upstream fix for boo#1173022
* Added patch 0001-Detect-broken-RDRAND-during-initialization.patch
* use URL from the releases page on github
* run spec-cleaner over the spec file
* Tue Apr 28 2020 Paolo Stivanin <info@paolostivanin.com>
- json-c 0.14:
* bits.h has been removed
* lh_abort() has been removed
* lh_table_lookup() has been removed, use lh_table_lookup_ex() instead.
* Remove TRUE and FALSE defines, use 1 and 0 instead.
* Switch to cmake
* Build fixes
* Doc updates
* Added a json_tokener_get_parse_end() function to replace
direct access of tok->char_offset
* json_tokener_parse_ex() now accepts a new JSON_TOKENER_VALIDATE_UTF8 flag
to validate that input is UTF8
* Add support for unsigned 64-bit integers
* A total of 7 new functions were added:
* json_object_get_uint64 ( struct json_object const* jso )
* json_object_new_uint64 ( uint64_t i )
* json_object_set_uint64 ( struct json_object* jso, uint64_t new_value )
* json_parse_uint64 ( char const* buf, uint64_t* retval )
* See description of uint64 support, above.
* json_tokener_get_parse_end ( struct json_tokener* tok )
* See details under "json_tokener changes", above.
* json_object_from_fd_ex ( int fd, int in_depth )
* Allows the max nesting depth to be specified.
* json_object_new_null ( )
* Simply returns NULL. Its use is not recommended.
* The size of struct json_object has decreased from 96 bytes to 88 bytes.
* Tue Mar 13 2018 avindra@opensuse.org
- json-c 0.13.1
* Add const size_t json_c_object_sizeof()
* Avoid invalid free (and thus a segfault) when ref_count gets < 0
* Fix handling of custom double formats that include a ".0"
* Avoid uninitialized variable warnings in json_object_object_foreach
* Add a top level fuzz directory for fuzzers run by OSS-Fuzz
* Fix build for certain uClibc based systems.
* Bump sonum to 4.0 to avoid conflicts because some packagers made
their own bump to ".so.3" for the older 0.12 release
* Thu Dec 28 2017 avindra@opensuse.org
- json-c 0.13
+ Deprecated and removed features:
* Internal use of bits.h has been eliminated.
* lh_abort() is deprecated
+ Behavior changes:
* Tighten the number parsing algorithm to raise errors instead
of truncating the results. For example 12.3.4 or 2015-01-15,
which now return null.
* Use size_t for array length and size. Platforms where
sizeof(size_t) != sizeof(int) may not be backwards compatible
* Check for failue when allocating memory, returning NULL and
errno=ENOMEM.
* 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)
+ New features:
* Aiming to follow RFC 7159 now.
* Support for JSON pointer, RFC 6901 (see json_pointer.h)
* Add a couple of additional option to json_object_to_json_string_ext:
JSON_C_TO_STRING_PRETTY_TAB
JSON_C_TO_STRING_NOSLASHESCAPE
* json_object_object_add_ex() - better perf when certain
constraints are known to be true
* Serialization format of doubles now configurable
* New functions
- json_object_equal() - utility function for comparing
json_objects
- json_object_deep_copy() - a way to copy entire object
trees
- json_object_set_<type>() - modify the value of
existing json_object's without the need to recreate them.
Also add a json_object_int_inc function to adjust an int's'
value.
- json_util_get_last_err() - retrieve the string describing
the cause of errors, instead of printing to stderr.
- perllike hash function for strings
* json_global_set_string_hash()
* json_c_visit() - a way to iterate over a tree of json-c
objects.
+ Notable bug fixes and other improvements:
* Make reference increment and decrement atomic to allow
passing json objects between threads.
* Fix json_object_object_foreach to avoid uninitialized
variable warnings.
* Improve performance by removing unneeded data items from
hashtable code and reducing duplicate hash computation.
* Performance: store small strings inside json_object
* Performance: of json_object_to_json_string by removing
variadic printf
* Fix parsing of "-Infinity", and avoid needlessly copying the
input when doing so.
* Fix stack buffer overflow in json_object_double_to_json_string_format()
* Fix various potential null ptr deref and int32 overflows
* 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.
* use uselocale() instead of setlocale() in json_tokener to
behave better in threaded environments.
* Fix out of bounds read when handling unicode surrogate pairs.
* Ensure doubles that happen to be a whole number are emitted
with ".0"
* Visual Studio: use a snprintf/vsnprintf wrapper that ensures
the string is terminated.
* Fix double to int cast overflow in json_object_get_int64.
* Clamp double to int32 when narrowing in json_object_get_int.
* Use strtoll() to parse ints - instead of sscanf
* usual code linting
+ Build changes:
* Add Appveyor and Travis build support
* Support for MacOS and Windows through CMake
* Silent build by default
* Link against libm when needed
* Add support for building with AddressSanitizer
* Add support for building with Clang
* Add a --enable-threading configure option, and only use the
(slower) __sync_add_and_fetch()/__sync_sub_and_fetch()
function when it is specified.
