From c80d25dbce759a8483ffc1f085fdf4cd63cf9f05 Mon Sep 17 00:00:00 2001 From: "Shawn O. Pearce" Date: Fri, 24 Aug 2007 23:15:50 -0400 Subject: [PATCH] git-gui: Correct 'git gui blame' in a subdirectory David Kastrup pointed out that the following sequence was not working as we had intended: $ cd lib $ git gui blame console.tcl fatal: cannot stat path lib/console.tcl: No such file or directory The problem here was we disabled the chdir to the root of the working tree when we are running with a "bare allowed" feature such as blame or browser, but we still kept the prefix we found via `git rev-parse --show-prefix`. This caused us to try and look for the file "console.tcl" within the subdirectory but also include the subdirectory's own path from the root of the working tree. This is unlikely to succeed, unless the user just happened to have a "lib/lib/console.tcl" file in the repository, in which case we would produce the wrong result. In the case of a bare repository we shouldn't get back a value from `rev-parse --show-prefix`, so really $_prefix should only be set to the non-empty string if we are in a working tree and we are in a subdirectory of that working tree. If this is true we really want to always be at the top level of the working tree, as all paths are accessed as though they were relative to the top of the working tree. Converting $_prefix to a ../ sequence is a fairly simple approach to moving up the requisite levels. Signed-off-by: Shawn O.
