Subject: [PATCH 05/12] vcs-svn: simplify repo_modify_path and repo_copy
Date: Sun, 6 Mar 2011 17:09:23 -0600 [thread overview]
Message-ID: <20110306230923.GG24327@elie> (raw)
In-Reply-To: <20110306225419.GA24327@elie>
Date: Fri, 10 Dec 2010 00:53:54 -0600
Restrict the repo_tree API to functions that are actually needed.
- decouple reading the mode and content of dirents from other
operations.
- remove repo_modify_path. It is only used to read the mode from
dirents.
- remove the ability to use repo_read_mode on a missing path. The
existing code only errors out in that case, anyway.
