All decoding functions now accept a json_error_t** parameter and set
it to point to a heap-allocated json_error_t structure if an error
occurs. The contents of json_error_t are no longer exposed directly, a
few functions to do it have been added instead. If an error occurs,
the user must free the json_error_t value.
This makes it possible to enhance the error reporting facilities in
the future without breaking ABI compatibility with older versions.
This is a backwards incompatible change.
As of now, the parameter is unused, but may be needed in the future.
I'm adding it now so that in the future both API and ABI remain
backwards compatible as long as possible.
This is a backwards incompatible change.
Replace all occurences of unsigned int and unsigned long with size_t.
This is a backwards incompatible change, as the signature of many API
functions changes.
When encoding an array or object ends in an error, the visited flag
wasn't zeroed, causing subsequent encoding attempts to fail. This
patch fixes the problem by always zeroing the visited flag.
Encoding an empty array or object worked, but encoding it again
(possibly after adding some items) failed, because the visited flag
(used for detecting circular references) wasn't zeroed.
Initialize their reference counts to (unsigned int)-1 to disable
reference counting on them. It already was meant to work like this,
but the reference counts were just initialized to 1 instead of -1.
Thanks to Andrew Thompson for reporting this issue.
With this encoding flag, the object key-value pairs in output are in
the same order in which they were first inserted into the object.
To make this possible, a key of an object is now a serial number plus
a string. An object keeps an increasing counter which is used to
assign serial number to the keys. Hashing, comparison and public API
functions were changed to act only on the string part, i.e. the serial
number is ignored everywhere else but in the encoder, where it's used
to order object keys if JSON_PRESERVE_ORDER flag is used.
Added functions are:
* json_string_nocheck()
* json_string_set_nocheck()
* json_object_set_nocheck()
* json_object_set_new_nocheck()
These functions don't check that their string argument is valid UTF-8,
but assume that the user has already performed the check.
* Now that JSON_SORT_KEYS is implemented, take it into use with the
valid and valid-strip suites. This is to ensure that the tests
remain valid even if the string hash function is changed in the
future.
* Remove test_dump API test. Instead, implement the same tests more
elegantly in the encoding-flags suite.
