Subject: luci-lib-jsonc: Ignore non-string-or-number keys in tables
|
||
|
|
|
||
|
|
Previously, the following caused a segmentation fault:
|
||
|
|
|
||
|
|
json.stringify({[{}] = true})
|
||
|
|
|
||
|
|
This was caused by lua_tostring() returning NULL for anything but
|
||
|
|
strings and numbers, letting json_object_object_add crash.
|
||
|
|
|
||
|
|
This patch makes jsonc ignore all keys which have no string
|
||
|
|
representation altogether.

||
