string-list: multi-delimiter `string_list_split_in_place()`

2023-04-24T23:01:28Z

Enhance `string_list_split_in_place()` to accept multiple characters as delimiters instead of a single character. Instead of using `strchr(2)` to locate the first occurrence of the given delimiter character, `string_list_split_in_place_multi()` uses `strcspn(2)` to move past the initial segment of characters comprised of any characters in the delimiting set. When only a single delimiting character is provided, `strpbrk(2)` (which is implemented with `strcspn(2)`) has equivalent performance to `strchr(2)`. Modern `strcspn(2)` implementations treat an empty delimiter or the singleton delimiter as a special case and fall back to calling strchrnul(). Both glibc[1] and musl[2] implement `strcspn(2)` this way. This change is one step to removing `strtok(2)` from the tree. Note that `string_list_split_in_place()` is not a strict replacement for `strtok()`, since it will happily turn sequential delimiter characters into empty entries in the resulting string_list. For example: string_list_split_in_place(&xs, "foo:;:bar:;:baz", ":;", -1) would yield a string list of: ["foo", "", "", "bar", "", "", "baz"] Callers that wish to emulate the behavior of strtok(2) more directly should call `string_list_remove_empty_items()` after splitting. To avoid regressions for the new multi-character delimter cases, update t0063 in this patch as well.

notes: clean up confusing NULL checks in init_notes()

2023-04-24T18:09:13Z

Coverity complains that we check whether "notes_ref" is NULL, but it was already implied to be non-NULL earlier in the function. And this is true; since b9342b3fd63 (refs: add array of ref namespaces, 2022-08-05), we call xstrdup(notes_ref) unconditionally, which would segfault if it was NULL. But that commit is actually doing the right thing. Even if NULL is passed into the function, we'll use default_notes_ref() as a fallback, which will never return NULL (it tries a few options, but its last resort is a string literal). Ironically, the "!notes_ref" check was added by the same commit that added the fallback: 709f79b0894 (Notes API: init_notes(): Initialize the notes tree from the given notes ref, 2010-02-13). So this check never did anything. Signed-off-by: Jeff King Signed-off-by: Junio C Hamano
