The decimal point '.' is changed to locale's decimal point
before/after JSON conversion to make C standard library's
locale-specific string conversion functions work correctly.
All the tests now call setlocale(LC_ALL, "") on startup to use the
locale set in the environment.
Fixes GH-32.
The keys which are stored temporarily to a hashtable to make sure that
all object keys are unpacked, were hashed with the object key hashing
function. It is meant to compute hashes for object_key_t values, and
it works incorrectly for plain strings.
Fixed by introducing suitable functions for hashing and comparing
strings for string-keyed hashtables.
* Use "printf" instead of "echo -n" as it's more portable
* Treat a test as skipped if it exits with exit status of 77
* Skip the check_exports test if "nm -D" doesn't work
- Add a new field position to the json_error_t structure. This is the
position in bytes from the beginning of the input.
- Keep track of line, column and input position in the stream level.
Previously, only line was tracked, and it was in the lexer level, so
this info was not available for UTF-8 decoding errors.
- While at it, refactor tests so that no separate "stripped" tests are
required. json_process is now able to strip whitespace from its
input, and the "valid" and "invalid" test suites now use this to
test both non-stripped and stripped input.
Closes GH-9.
Thanks to Basile Starynkevitch for the suggestion and initial patch.
Thanks to Jonathan Landis and Deron Meranda for showing how this can
be utilized for implementing secure memory operations.
Expand the pack/unpack API: json_(un)pack is the simple version with
no error output, json_(un)pack_ex has error output and flags,
json_v(un)pack_ex is a va_list version of json_(un)pack_ex.
Implement unpacking flags:
- JSON_UNPACK_ONLY turns off extra validation, i.e. array and object
unpacking doesn't check that all items are unpacked. This is really
just convenience for not adding '*' after each object and array.
- JSON_VALIDATE_ONLY turns off unpacking, i.e. no varargs are expected
and nothing is unpacked.
* Implement a "scanner" that reads the format string, maintaining state
* Split json_vnpack() to three separate functions for packing objects,
arrays and simple values. This makes it more clear what is being
packed, and the object and array structures become more evident.
* Make the skipping of ignored character simpler, i.e. skip ':' and
',' independent of their context
This patch shaves around 80 lines of code from the original
implementation.
Note that we pass va_list pointers around instead of just va_lists, which
would seem more intuitive. This is necessary since the behaviour of va_lists
passed as function parameters is finicky. Quoth stdarg(3):
If ap is passed to a function that uses va_arg(ap,type) then the value
of ap is undefined after the return of that function.
The pointer-passing strategy is used by Python's Py_BuildValue() for the same
purpose.
