The series below makes changes like these mechanically,
one class of change per change-set:
strcmp(...) == 0 to STREQ(...)
strcmp(...) != 0 to STRNEQ(...)
strncmp(...) == 0 to STREQLEN(...)
strncmp(...) != 0 to STRNEQLEN(...)
strcasecmp(...) == 0 to STRCASEEQ(...)
strcasecmp(...) != 0 to STRCASENEQ(...)
strncasecmp(...) == 0 to STRCASEEQLEN(...)
strncasecmp(...) != 0 to STRCASENEQLEN(...)
Then it enables the "make syntax-check" tests to ensure
no offending (convertable) use is introduced.
But there's one twist.
In order for the substitution commands to work as-is,
I first converted str*cmp functions, and *then* added
the #define stmts. Afterwards, I used git rebase -i to
move the final #define-adding-commit to precede the others.
That makes it so that the code compiles after each new change set.
If I'd added the #defines before performing the substitutions,
I would have had to make the commands more involved to keep
them from transforming the #defines.
Just noticed that the actual definitions are
over-parenthesized, and can be simplified to this:
#define STREQ(a,b) (strcmp(a,b) == 0)
#define STRNEQ(a,b) (!STREQ(a,b))
#define STRCASEEQ(a,b) (strcasecmp(a,b) == 0)
#define STRCASENEQ(a,b) (!STRCASEEQ(a,b))
#define STREQLEN(a,b,n) (strncmp(a,b,n) == 0)
#define STRNEQLEN(a,b,n) (!STREQLEN(a,b,n))
#define STRCASEEQLEN(a,b,n) (strncasecmp(a,b,n) == 0)
#define STRCASENEQLEN(a,b,n) (!STRCASEEQLEN(a,b,n))
#define STRPREFIX(a,b) (strncmp((a),(b),strlen((b))) == 0)
I'll adjust to use the above tomorrow.
--------------------------------------------->From a reviewer's perspective, it's useful to know that 2-8
were done mechanically. Only 1 and 10 were done manually.
This has not yet passed "make check", possibly due to unrelated
problems.
