Previously, git-credential-store only supported storing credentials in a single file: ~/.git-credentials. In order to support the XDG base directory specification[1], git-credential-store needs to be able to lookup and erase credentials from multiple files, as well as to pick the appropriate file to write to so that the credentials can be found on subsequent lookups. [1] http://standards.freedesktop.org/basedir-spec/basedir-spec-0.7.html Note that some credential storage files may not be owned, readable or writable by the user, as they may be system-wide files that are meant to apply to every user. Instead of a single file path, lookup_credential(), remove_credential() and store_credential() now take a precedence-ordered string_list of file paths. lookup_credential() expects both user-specific and system-wide credential files to be provided to support the use case of system administrators setting default credentials for users. remove_credential() and store_credential() expect only the user-specific credential files to be provided as usually the only config files that users are allowed to edit are their own user-specific ones. lookup_credential() will read these (user-specific and system-wide) file paths in order until it finds the 1st matching credential and print it. As some files may be private and thus unreadable, any file which cannot be read will be ignored silently. remove_credential() will erase credentials from all (user-specific) files in the list. This is because if credentials are only erased from the file with the highest precedence, a matching credential may still be found in a file further down the list. (Note that due to the lockfile code, this requires the directory to be writable, which should be so for user-specific config files) store_credential() will write the credentials to the first existing (user-specific) file in the list. If none of the files in the list exist, store_credential() will write to the filename specified by the first item of the filename list. For backwards compatibility, this filename should be "~/.git-credentials". Helped-by:
