Tobias Stoeckmann bcb6d7d347 Handle allocation failure in json_tokener_new_ex 
The allocation of printbuf_new might fail. Return NULL to indicate tis
error to the caller. Otherwise later usage of the returned tokener would
lead to null pointer dereference.

Eric Haszlakiewicz a4e3700972 Fix code formatting 2020-06-29 02:31:18 +00:00
Eric Haszlakiewicz f23486a321 In the json_tokener_state_number case, explicitly adjust what "number" characters are allowed based on the exact micro-state that we're in, and check for invalid following characters in a different way, to allow a valid json_type_number object to be returned at the top level. 
This causes previously failing strings like "123-456" to return a valid json_object with the appropriate value.  If you care about the trailing content, call json_tokener_parse_ex() and check the parse end point with json_tokener_get_parse_end().

Eric Haszlakiewicz a68566bf6a Issue #616: Change the parsing of surrogate pairs in unicode escapes so it uses a couple of additional states instead of assuming the low surrogate is already present, to ensure that we correctly handle various cases of incremental parsing. 2020-06-21 18:29:57 +00:00
Eric Haszlakiewicz 36118b681e Rearrange the json_tokener_state_escape_unicode case in json_tokener to simplify the code slightly and make it a bit easier to understand. 
While here, drop the utf8_replacement_char that is unnecesarily added if we run out of input in the middle of a unicode escape.  No other functional changes (yet).

Eric Haszlakiewicz e26a1195f4 Add json_object_array_shrink() (and array_list_shrink()) and use it in json_tokener to minimize the amount of memory used. This results in a 39%-50% reduction in memory use (peak RSS, peak heap usage) on the jc-bench benchmark and 9% shorter runtime. 
Also add the json_object_new_array_ext, array_list_new2, and array_list_shrink functions.

Eric Haszlakiewicz 374ffe87c6 Issue #463: fix newlocale() call to use LC_NUMERIC_MASK instead of LC_NUMERIC, and remove incorrect comment. 
The second call to newlocale() with LC_TIME accidentally made things

Emmanuele Bassi 7601f20d70 Revert "compat/strdup.h: move common compat check for strdup() to own file" 
This reverts commit aaba8c1080.

This commit breaks builddir != srcdir build, but, more importantly, it
also adds a dependency on a header, "config.h", which is not installed
and it's supposed to be private — since it's generated at configuration
time and it's not meant to be used by projects compiling against a
library.

Eric Haszlakiewicz 4d62de3898 Revert bogus change to json_object_get() made in f40b08d8 that caused it to always return NULL. (Issue #259) 
Also undo NULL check in json_tokener_set_flags(): it's not at all valid toi
 try to set flags on a NULL pointer, and doing so should not be silently
 ignored.

Eric Haszlakiewicz fa76e4a8c9 Issue #195: Actually call uselocale() in the new locale handling code in json_tokener. 
Also, be sure the right locale_t is freed if we fail on the second uselocale.
Finally, fix test_locale so it *doesn't* use json_object_to_json_string as
 that will simple re-emit the original parsed string values.

Tightening the number parsing algorithm
 2015-03-03 22:41:31 -05:00
chl 99d8fc975e Tightening the number parsing algorithm 
Some badly formated "numbers" could get partly parsed,
resulting in truncated results instead of raising an
error.

Examples :
 '1.2.3'      -> (double)1.2
 '2015-01-15' -> (int)2015

This patch is not perfect (ex: input can still end with a 'E', which
is forbidden by json.org doc) but should avoid non-sensically
formated input.

Tests added.
