From: Paul-Sebastian Ungureanu Date: Fri, 23 Feb 2018 16:25:57 +0000 (+0200) Subject: ref-filter: make "--contains " less chatty if is invalid X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/fcfba37337 ref-filter: make "--contains " less chatty if is invalid Some git commands which use --contains print the whole help text if is invalid. It should only show the error message instead. This patch applies to "git tag", "git branch", "git for-each-ref". This bug was a side effect of looking up the commit in option parser callback. When a error occurs in the option parser, the full usage is shown. To fix this bug, the part related to looking up the commit was moved outside of the option parser to the ref-filter module. Basically, the option parser only parses strings that represent commits and the ref-filter performs the commit look-up. If an error occurs during the option parsing, then it must be an invalid argument and the user should be informed of usage, but if a error occurs during ref-filtering, then it is a problem with the argument.
