From: Junio C Hamano Date: Fri, 28 Oct 2016 19:25:30 +0000 (-0700) Subject: push: do not use potentially ambiguous default refspec X-Git-Tag: v2.11.1~41^2~1 X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=eef2bdaa4a979994a22dbc5c2e7c5b8a9d2a2043;p=git-core%2Fgit.git push: do not use potentially ambiguous default refspec When the user does the lazy "git push" with no parameters with push.default set to either "upstream", "simple" or "current", we internally generated a refspec that has the current branch name on the source side and used it to push. However, the branch name (say "test") may be an ambiguous refname in the context of the source repository---there may be a tag with the same name, for example. This would trigger an unnecessary error without any fault on the end-user's side. Be explicit and give a full refname as the source side to avoid the ambiguity. The destination side when pushing with the "current" sent only the name of the branch and forcing the receiving end to guess, which is the same issue. Be explicit there as well.
