From 9478b11968d61085bb4c4343395b6f52ce06380f Mon Sep 17 00:00:00 2001 From: Ammon Riley Date: Thu, 30 Aug 2012 15:53:57 -0700 Subject: [PATCH] Make git-svn branch patterns match complete URL When using the {word,[...]} style of configuration for tags and branches, it appears the intent is to only match whole path parts, since the words in the {} pattern are meta-character quoted. When the pattern word appears in the beginning or middle of the url, it's matched completely, since the left side, pattern, and (non-empty) right side are joined together with path separators. However, when the pattern word appears at the end of the URL, the right side is an empty pattern, and the resulting regex matches more than just the specified pattern. For example, if you specify something along the lines of branches = branches/project/{release_1,release_2} and your repository also contains "branches/project/release_1_2", you will also get the release_1_2 branch. By restricting the match regex with anchors, this is avoided.
