René Scharfe	76d8d45ffb	coccinelle: polish FREE_AND_NULL rules There are two rules for using FREE_AND_NULL in free.cocci, one for pointer types and one for expressions. Both cause coccinelle to remove empty lines and even newline characters between replacements for some reason; consecutive "free(x);/x=NULL;" sequences end up as multiple FREE_AND_NULL calls on the same time. Remove the type rule, as the expression rule already covers it, and rearrange the lines of the latter to place the addition of FREE_AND_NULL between the removals, which causes coccinelle to leave surrounding whitespace untouched.

Ævar Arnfjörð Bjarmason	1b83d1251e	coccinelle: add a rule to make "expression" code use FREE_AND_NULL() A follow-up to the existing "type" rule added in an earlier change. This catches some occurrences that are missed by the previous rule. Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	8 years ago

René Scharfe	ec6cd14c7a	cocci: detect useless free(3) calls Add a semantic patch for removing checks that cause free(3) to only be called with a NULL pointer, as that must be a programming mistake.

René Scharfe	39ea59a257	remove unnecessary NULL check before free(3) free(3) handles NULL pointers just fine. Add a semantic patch for removing unnecessary NULL checks before calling this function, and apply it on the code base.
