* coccinelle: skip the empty-to-null transformation on the macro itselfFrantisek Sumsal2023-01-251-2/+6
| | | | | | | | Since the empty_to_null() function was "macrofied", we need to use a bit of black magic to make Coccinelle avoid running the transformation on the macro itself. Follow-up to ef2409cbde3.
* licensing: add spdx to our .cocci filesZbigniew Jędrzejewski-Szmek2021-10-011-0/+1
| | | | | Since those are chunks of code based on our codebase, it's easiest to use the same license.
* coccinelle: ignore function transformations causing recursionFrantisek Sumsal2019-04-291-1/+4
| | | | | | | | | | | | | | | | | | | | | | For example, following transformation: - isempty(s) ? NULL : s + empty_to_null(s) would get applied to the empty_to_null function itself as well, causing an infinite recursion, like: --- src/basic/string-util.h +++ /tmp/cocci-output-307-9f76e6-string-util.h @@ -50,11 +50,11 @@ static inline bool isempty(const char *p } static inline const char *empty_to_null(const char *p) { - return isempty(p) ?
