This is to better catch distribution errors. It's easier to notice
that run-tests fails than to notice that one of many test suites is
silently skipped.
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.
- Never append newline to output
- By default, add spaces between array and object items for more
readable output
- Introduce the flag JSON_COMPACT to not add the aforementioned spaces
Failing to do this has the effect that the error message is not
returned when the input file cannot be opened (e.g. if it doesn't
exist).
Thanks to Martin Vopatek for reporting.
It's now an error to try to add an object or array to itself. The
encoder checks for circular references and fails with an error status
if one is detected.
Added functions:
json_string_set
json_integer_set
json_real_set
While at it, clarify the documentation and parameter naming of
json_{string,integer,real}_value() a bit.
That is, test cases where there's no newline or other whitespace at
the beginning or end of input. This was implemented by adding a
--strip option to split-testfile to strip the input file after writing
it.
The actual test JSON texts are the same as testdata/invalid and
testdata/valid. The expected output of the invalid cases had to be
adjusted a bit: because there's no newline at the end, some of the
line numbers needed to be changed.
All pointer arguments are now tested for NULL. json_string() now also
tests that strdup() succeeds. This is to ensure that no NULL values
end up in data structures.
Also desribe the different sources of errors in documentation.
