Subject: [PATCH 4/4] attr.c: fix matching "subdir" without the trailing slash
Date: Mon, 25 Mar 2013 13:05:10 +0700 [thread overview]
Message-ID: <1364191510-8900-5-git-send-email-pclouds@gmail.com> (raw)
In-Reply-To: <1364191510-8900-1-git-send-email-pclouds@gmail.com>
The story goes back to 94bc671 (Add directory pattern matching to
attributes - 2012-12-08). Before this commit, directories are passed
to path_matches without the trailing slash. This is fine for matching
pattern "subdir" with "foo/subdir".
Patterns like "subdir/" (i.e. match _directory_ subdir) won't work
though. So paths are now passed to path_matches with the trailing
slash (i.e. "subdir/"). The trailing slash is used as the directory
indicator (similar to dtype in exclude case). This makes pattern
"subdir/" match directory "subdir/". Pattern "subdir" no longer match
subdir, which is now "subdir/".
As the trailing slash in pathname is the directory indicator, we do
not need to keep it in the pathname for matching. The trailing slash
should be turned to dtype "DT_DIR" and stripped out of pathname. This
keeps the code pattern similar to exclude.
The same applies for the pattern "subdir/". The trailing slash is
converted to flag EXC_FLAG_MUSTBEDIR and should not remain in the
pattern, as noted in parse_exclude_pattern(). prepare_attr_stack()
breaks this and keeps the trailing slash anyway.
To sum up, both patterns and pathnames should never have the trailing
slash when it comes to match_basename.
