Subject: [PATCH 2/3] parse-options: allow --end-of-options as a synonym for "--"
Date: Tue, 6 Aug 2019 10:40:16 -0400 [thread overview]
Message-ID: <20190806144015.GB2161@sigill.intra.peff.net> (raw)
In-Reply-To: <20190806143829.GA515@sigill.intra.peff.net>
The revision option parser recently learned about --end-of-options, but
that's not quite enough for all callers. Some of them, like git-log,
pick out some options using parse_options(), and then feed the remainder
to setup_revisions(). For those cases we need to stop parse_options()
from finding more options when it sees --end-of-options, and to retain
that option in argv so that setup_revisions() can see it as well.
Let's handle this the same as we do "--". We can even piggy-back on the
handling of PARSE_OPT_KEEP_DASHDASH, because any caller that wants to
retain one will want to retain the other.
I've included two tests here. The "log" test covers "--source", which is
one of the options it handles with parse_options(), and would fail
before this patch. There's also a test that uses the parse-options
helper directly. That confirms that the option is handled correctly even
in cases without KEEP_DASHDASH or setup_revisions(). I.e., it is safe to
use --end-of-options in place of "--" in other programs.
