./textproc/json-c, JSON library in C

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 0.16, Package name: json-c-0.16, Maintainer: ryoon

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.

Log message:
json-c: introduce an option to build the documentation

The option is left off by default; hence no functional change nor
PKGREVISION bump necessary.

Tested on NetBSD/amd64.

Log message:
json-c: update to 0.16.

0.16 (up to commit 66dcdf5, 2022-04-13)

Deprecated and removed features:
* JSON_C_OBJECT_KEY_IS_CONSTANT is deprecated in favor of
* Direct access to lh_table and lh_entry structure members is deprecated.
  Use access functions instead, lh_table_head(), lh_entry_next(), etc...

New features
* The 0.16 release introduces no new features

Build changes
* Add a DISABLE_EXTRA_LIBS option to skip using libbsd
* Add a DISABLE_JSON_POINTER option to skip compiling in json_pointer support.

Significant 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

* 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.

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()

textproc: Replace RMD160 checksums with BLAKE2s checksums

All checksums have been double-checked against existing RMD160 and
SHA512 hashes

textproc: Remove SHA1 hashes for distfiles
   2020-10-01 11:16:12 by Thomas Klausner | Files touched by this commit (3) | Package updated
Log message:
json-c: update to 0.15.

Next Release 0.15

Deprecated and removed features:
* Deprecate `array_list_new()` in favor of `array_list_new2()`
* 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
