Subject: [PATCH 04/75] parse-options: disable option abbreviation with PARSE_OPT_KEEP_UNKNOWN
Date: Thu, 27 Dec 2018 17:25:25 +0100 [thread overview]
Message-ID: <20181227162536.15895-5-pclouds@gmail.com> (raw)
In-Reply-To: <20181227162536.15895-1-pclouds@gmail.com>
parse-options can unambiguously find an abbreviation only if it sees
all available options. This is usually the case when you use
parse_options(). But there are other callers like blame or shortlog
which uses parse_options_start() in combination with a custom option
parser, like rev-list. parse-options cannot see all options in this
case and will get abbrev detection wrong. Disable it.
t7800 needs update because --symlink no longer expands to --symlinks
and will be passed down to git-diff, which will not recognize it. I
still think this is the correct thing to do. But if --symlink has been
actually used in the wild, we would just add an option alias for it.
