From 0b2af457a49e3b00d47d556d5301934d27909db8 Mon Sep 17 00:00:00 2001 From: Mattias Nissler Date: Tue, 7 Jul 2009 01:40:02 +0200 Subject: [PATCH] git-svn: Fix branch detection when repository root is inaccessible For the case of multiple projects sharing a single SVN repository, it is common practice to create the standard SVN directory layout within a subdirectory for each project. In such setups, access control is often used to limit what projects a given user may access. git-svn failed to detect branches (e.g. when passing --stdlayout to clone) because it relied on having access to the root directory in the repository. This patch solves this problem by making git-svn use paths relative to the given repository URL instead of the repository root.
