[PATCH v2 2/3] dir: improve naming of oid_stat fields in two structs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Both "struct untracked_cache" and "struct dir_struct" contain fields of
the type "struct oid_stat". The latter used to be called "sha1_stat"
before 4b33e60 ("dir: convert struct sha1_stat to use object_id",
2018-01-28). Although this struct was renamed, the previously mentioned
fields are still named with an "ss_" prefix ("ss_info_exclude" and
"ss_excludes_file"), which refers to the old "sha1_stat". As this can be
confusing, let's rename these fields. Since "struct oid_stat" is used to
query the validity of cached data, a better naming alternative would be
"info_exclude_validity" and "excludes_file_validity".
