From: Jeff King Date: Mon, 5 Nov 2018 06:39:20 +0000 (-0500) Subject: ls-files: mark exclude options as NONEG X-Git-Tag: v2.20.0-rc0~23^2~11 X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/ccf659e87c8fdb4edb5d2653c53bc9062c8eee76 ls-files: mark exclude options as NONEG Running "git ls-files --no-exclude" will currently segfault, as its option callback does not handle the "unset" parameter. In theory this could be used to clear the exclude list, but it is not clear how that would interact with the other exclude options, nor is the current code capable of clearing the list. Let's just disable the broken option. Note that --no-exclude-from will similarly segfault, but --no-exclude-standard will not. It just silently does the wrong thing (pretending as if --exclude-standard was specified).
