From: Michael J Gruber Date: Tue, 17 May 2011 15:38:53 +0000 (+0200) Subject: config: Give error message when not changing a multivar X-Git-Tag: v1.7.6-rc0~42^2 X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=5a2df368c26e4a993db9d09f221af1063d0fe9a8;p=git.git config: Give error message when not changing a multivar When trying to set a multivar with "git config var value", "git config" issues warning: remote.repoor.push has multiple values leaving the user under the impression that the operation succeeded, unless one checks the return value. Instead, make it warning: remote.repoor.push has multiple values error: cannot overwrite multiple values with a single value Use a regexp, --add or --set-all to change remote.repoor.push. to be clear and helpful. Note: The "warning" is raised through other code paths also so that it needs to remain a warning for these (which do not raise the error). Only the caller can determine how to go on from that.
