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 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
