From e95c70d4ea997d1217d5c81cb3b640f3fa025df1 Mon Sep 17 00:00:00 2001 From: Lars Hjemli Date: Mon, 20 Jun 2011 20:59:10 +0200 Subject: Only guess default branch when a repo page is requested There's no need to invoke guess_defbranch() for each repo during scan-path, since repo.defbranch is only used when repo content is being displayed. Also, some users prefer to register their projects manually in cgitrc but they got no benefit from the new repo.defbranch handling. This patch tries to rectify these issues by only invoking guess_defbranch() when needed, regardless of how the repo was registered.
