[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v2 1/1] scripts: warn about invalid MAINTAINERS patterns
Add "--self-test" option to get_maintainer.pl to show potential
issues in MAINTAINERS file(s) content.
Pattern check warnings are shown for "F" and "X" patterns found in
MAINTAINERS file(s) which do not match any files known by git.

v2:
Incorporated suggestions from Joe Perches:
- changed "--pattern-checks" to "--self-test" to allow for future work.
- fixed vcs command "list_files_cmd" for mercurial.
- "--self-test" option is all or nothing.
- output to STDOUT
- output format in emacs-style "filename:line: message"
- changed self-test help to:
--self-test => show potential issues with MAINTAINERS file content
(Joe, I slightly reworded in hopes this rendition is clear and future proof).
- Moved execution of $self_test to just after $help and $version.
This prompted encapsulating main content code to read MAINTAINERS files into
a function (read_all_maintainer_files) callable from $self_test. This
has the side benefit of not having to special case for "$self_test" in other
parts
of main program flow.
