From 3952710bfaa46917fd0c3a9b29d076ec013d6b6a Mon Sep 17 00:00:00 2001 From: Ian Wienand Date: Fri, 11 Feb 2011 16:33:48 -0800 Subject: [PATCH] Obey p4 views when using client spec When using the p4 client spec, this attempts to obey the client's output preferences. For example, a view like //depot/foo/branch/... //client/branch/foo/... //depot/bar/branch/... //client/branch/bar/... will result in a directory layout in the git tree of branch/ branch/foo branch/bar p4 can do various other reordering that this change doesn't support, but we should detect it and at least fail nicely.
