| | | | | | | | | | | | | | | | | * doc/lispref/text.texi (Parsing JSON): Describe new arguments of json-serialize and json-insert. * src/json.c (enum json_object_type, struct json_configuration): Move up in file before first usage. (lisp_to_json_toplevel, lisp_to_json_toplevel_1, lisp_to_json): Accept a struct json_configuration*. (Fjson_serialize, Fjson_insert): Accept multiple args. (json_parse_args): Accept new boolean configure_object_type. * test/src/json-tests.el (json-serialize, json-insert): Update forward decls.

* Fix pointer misuse in JSON parserPaul Eggert2018-06-091-32/+28
| | | | | | | | | * src/json.c (lisp_to_json_toplevel_1): Fix pointer misuse not caught by C type checking (json_t ** converted to void * where the program expected json_t *). Bug caught on Fedora 28 x86-64 via './configure CFLAGS="-g3 -O2 -fsanitize=address" CANNOT_DUMP=yes'. Avoid similar problems in the future by rewriting to use json_t * instead of json_t **.
