Other changes ------------- * 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() *** 0.15 (up to commit 870965e, 2020/07/26) ======================================== Deprecated and removed features: -------------------------------- * Deprecate `array_list_new()` in favor of `array_list_new2()` * Remove the THIS_FUNCTION_IS_DEPRECATED define. * Remove config.h.win32 New features ------------ * 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). Build changes ------------- * #639/#621 - Add symbol versions to all exported symbols * #508/#634 - Always enable -fPIC to allow use of the json-c static library in other libraries * Build both static and shared libraries at the same time. * #626 - Restore compatibility with cmake 2.8 * #471 - Always create directories with mode 0755, regardless of umask. * #606/#604 - Improve support for OSes like AIX and IBM i, as well as for MINGW32 and old versions of MSVC * #451/#617 - Add a DISABLE_THREAD_LOCAL_STORAGE cmake option to disable the use of thread-local storage. Significant changes and bug fixes --------------------------------- * 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". Other changes ------------- * #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 created 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 *** 0.14 (up to commit 9ed00a6, 2020/04/14) ========================================= Deprecated and removed features: -------------------------------- * 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. Build changes: -------------- ## Deprecated and removed features: * 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. * autoconf support, including autogen.sh, has been removed. See details about cmake, below. * 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. * 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. * Reports of success, or pull requests to correct issues are welcome. ## Notable improvements and new features ### Builds and documentation * Build machinery has been switched to CMake. See README.md for details about how to build. * TL;DR: `mkdir build ; cd build ; cmake -DCMAKE_INSTALL_PREFIX=/some/path ../json-c ; make all test install` * To ease the transition, there is a `cmake-configure` wrapper that emulates the old autoconf-based configure script. * 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. * The json-c style guide has been updated to specify the use of clang-format, and all code has been reformatted. * Since many lines of code have trivial changes now, when using git blame, be sure to specify -w * Numerous improvements have been made to the documentation including function effects on refcounts, when passing a NULL is safe, and so on. ### json_tokener changes * Added a json_tokener_get_parse_end() function to replace direct access of tok->char_offset. * 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 * json_tokener_parse_ex() now accepts a new JSON_TOKENER_VALIDATE_UTF8 flag to validate that input is UTF8. * If validation fails, json_tokener_get_error(tok) will return json_tokener_error_parse_utf8_string (see enum json_tokener_error). ### Other changes and additions * Add support for unsigned 64-bit integers, uint64_t, to gain one extra bit of magnitude for positive ints. * json_tokener will now parse values up to UINT64_MAX (18446744073709551615) * Existing methods returning int32_t or int64_t will cap out-of-range values at INT32_MAX or INT64_MAX, preserving existing behavior. * The implementation includes the possibility of easily extending this to larger sizes in the future. * 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. ### Testing * Many updates were made to test cases, increasing code coverage. * There is now a quick way (JSONC_TEST_TRACE=1) to turn on shell tracing in tests. * To run tests, use `make test`; the old "check" target no longer exists. ## Significant bug fixes For the full list of issues and pull requests since the previous release, please see issues_closed_for_0.14.md * [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. * [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. * [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. * [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. * [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. * [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. * [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. * [Issue #488](https://github.com/json-c/json-c/issues/488): use JSON_EXPORT on functions so they are properly exported on Windows. * [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. *** 0.13.1 (up to commit 0f814e5, 2018/03/04) ========================================= * Bump the major version of the .so library generated up to 4.0 to avoid conflicts because some downstream packagers of json-c had already done their own bump to ".so.3" for a much older 0.12 release. * Add const size_t json_c_object_sizeof() * Avoid invalid free (and thus a segfault) when ref_count gets < 0 * PR#394: fix handling of custom double formats that include a ".0" * Avoid uninitialized variable warnings in json_object_object_foreach * Issue #396: fix build for certain uClibc based systems. * Add a top level fuzz directory for fuzzers run by OSS-Fuzz 0.13 (up to commit 5dae561, 2017/11/29) ================================= This release, being three and a half years after the 0.12 branch (f84d9c), has quite a number of changes included. The following is a sampling of the most significant ones. Since the 0.12 release, 250 issues and pull requests have been closed. See issues_closed_for_0.13.md for a complete list. Deprecated and removed features: -------------------------------- * All internal use of bits.h has been eliminated. The file will be removed. Do not use: hexdigit(), error_ptr(), error_descrition() and it_error() * lh_abort() is deprecated. It will be removed. 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. See commit 99d8fc * Use size_t for array length and size. Platforms where sizeof(size_t) != sizeof(int) may not be backwards compatible See commits 45c56b, 92e9a5 and others. * Check for failure when allocating memory, returning NULL and errno=ENOMEM. See commit 2149a04. * 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: ------------- * We're aiming to follow RFC 7159 now. * Add a couple of additional option to json_object_to_json_string_ext: JSON_C_TO_STRING_PRETTY_TAB JSON_C_TO_STRING_NOSLASHESCAPE * Add a json_object_object_add_ex() function to allow for performance improvements when certain constraints are known to be true. * Make serialization format of doubles configurable, in two different ways: Call json_object_set_serializer with json_object_double_to_json_string and a custom format on each double object, or Call json_c_set_serialization_double_format() to set a global or thread-wide format. * Add utility function for comparing json_objects - json_object_equal() * Add a way to copy entire object trees: json_object_deep_copy() * Add json_object_set_ function to 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. * Add support for JSON pointer, RFC 6901. See json_pointer.h * Add a json_util_get_last_err() function to retrieve the string describing the cause of errors, instead of printing to stderr. * Add perllike hash function for strings, and json_global_set_string_hash() 8f8d03d * Add a json_c_visit() function to provide 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. * Improve performance by storing small strings inside json_object * Improve performance of json_object_to_json_string by removing variadic printf. commit 9ff0f49 * Issue #371: 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() - commit 2c2deb87 * Fix various potential null ptr deref and int32 overflows * 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. * Issue #195: use uselocale() instead of setlocale() in json_tokener to behave better in threaded environments. * Issue #275: fix out of bounds read when handling unicode surrogate pairs. * Ensure doubles that happen to be a whole number are emitted with ".0" - commit ca7a19 * PR#331: for 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 * Miscellaneous smaller changes, including removing unused variables, fixing warning about uninitialized variables adding const qualifiers, reformatting code, etc... Build changes: -------------- * Add Appveyor and Travis build support * Switch to using CMake when building on Windows with Visual Studio. A dynamic .dll is generated instead of a .lib config.h is now generated, config.h.win32 should no longer be manually copied * Add support for MacOS through CMake too. * Enable 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. List of new functions added: ---------------------------- ### json_object.h * array_list_bsearch() * array_list_del_idx() * json_object_to_json_string_length() * json_object_get_userdata() * json_object_set_userdata() * json_object_object_add_ex() * json_object_array_bsearch() * json_object_array_del_idx() * json_object_set_boolean() * json_object_set_int() * json_object_int_inc() * json_object_set_int64() * json_c_set_serialization_double_format() * json_object_double_to_json_string() * json_object_set_double() * json_object_set_string() * json_object_set_string_len() * json_object_equal() * json_object_deep_copy() ### json_pointer.h * json_pointer_get() * json_pointer_getf() * json_pointer_set() * json_pointer_setf() ### json_util.h * json_object_from_fd() * json_object_to_fd() * json_util_get_last_err() ### json_visit.h * json_c_visit() ### linkhash.h * json_global_set_string_hash() * lh_table_resize() ### printbuf.h * printbuf_strappend() 0.12.1 ====== * Minimal changes to address compile issues. 0.12 ==== * Address security issues: * CVE-2013-6371: hash collision denial of service * CVE-2013-6370: buffer overflow if size_t is larger than int * Avoid potential overflow in json_object_get_double * Eliminate the mc_abort() function and MC_ABORT macro. * Make the json_tokener_errors array local. It has been deprecated for a while, and json_tokener_error_desc() should be used instead. * change the floating point output format to %.17g so values with more than 6 digits show up in the output. * Remove the old libjson.so name compatibility support. The library is only created as libjson-c.so now and headers are only installed into the ${prefix}/json-c directory. * When supported by the linker, add the -Bsymbolic-functions flag. * Various changes to fix the build on MSVC. * Make strict mode more strict: * number must not start with 0 * no single-quote strings * no comments * trailing char not allowed * only allow lowercase literals * Added a json_object_new_double_s() convenience function to allow an exact string representation of a double to be specified when creating the object and use it in json_tokener_parse_ex() so a re-serialized object more exactly matches the input. * Add support NaN and Infinity 0.11 ==== * IMPORTANT: the name of the library has changed to libjson-c.so and the header files are now in include/json-c. The pkgconfig name has also changed from json to json-c. You should change your build to use appropriate -I and -l options. A compatibility shim is in place so builds using the old name will continue to work, but that will be removed in the next release. * Maximum recursion depth is now a runtime option. json_tokener_new() is provided for compatibility. json_tokener_new_ex(depth) * Include json_object_iterator.h in the installed headers. * Add support for building on Android. * Rewrite json_object_object_add to replace just the value if the key already exists so keys remain valid. * Make it safe to delete keys while iterating with the json_object_object_foreach macro. * Add a json_set_serializer() function to allow the string output of a json_object to be customized. * Make float parsing locale independent. * Add a json_tokener_set_flags() function and a JSON_TOKENER_STRICT flag. * Enable -Werror when building. * speed improvements to parsing 64-bit integers on systems with working sscanf * Add a json_object_object_length function. * Fix a bug (buffer overrun) when expanding arrays to more than 64 entries. 0.10 ==== * Add a json_object_to_json_string_ext() function to allow output to be formatted in a more human readable form. * Add json_object_object_get_ex(), a NULL-safe get object method, to be able to distinguish between a key not present and the value being NULL. * Add an alternative iterator implementation, see json_object_iterator.h * Make json_object_iter public to enable external use of the json_object_object_foreachC macro. * Add a printbuf_memset() function to provide an efficient way to set and append things like whitespace indentation. * Adjust json_object_is_type and json_object_get_type so they return json_type_null for NULL objects and handle NULL passed to json_objct_object_get(). * Rename boolean type to json_bool. * Fix various compile issues for Visual Studio and MinGW. * Allow json_tokener_parse_ex() to be re-used to parse multiple object. Also, fix some parsing issues with capitalized hexadecimal numbers and number in E notation. * Add json_tokener_get_error() and json_tokener_error_desc() to better encapsulate the process of retrieving errors while parsing. * Various improvements to the documentation of many functions. * Add new json_object_array_sort() function. * Fix a bug in json_object_get_int(), which would incorrectly return 0 when called on a string type object. Eric Haszlakiewicz * Add a json_type_to_name() function. Eric Haszlakiewicz * Add a json_tokener_parse_verbose() function. Jehiah Czebotar * Improve support for null bytes within JSON strings.
