Hi Pat,

I'm running git 2.0.0-rc0 (haven't got round to pulling down rc1 yet)
which includes gitgui-0.19.0 and I'm getting a new error when I run
'git gui' in a repository with a .git file (created by git submodule).

I can send you a screencap of the error message off list if you want
but the text is

"No working directory ../../../<repo>

couldn't change working directory to ../../../<repo>: no such file or directory"

My tcl is a little rusty but I think the problem might be this snippet.

# v1.7.0 introduced --show-toplevel to return the canonical work-tree
if {[package vsatisfies $_git_version 1.7.0]} {
   if { [is_Cygwin] } {
       catch {set _gitworktree [exec cygpath --windows [git rev-parse
--show-toplevel]]}
   } else {
       set _gitworktree [git rev-parse --show-toplevel]
   }
} else {
   # try to set work tree from environment, core.worktree or use
   # cdup to obtain a relative path to the top of the worktree. If
   # run from the top, the ./ prefix ensures normalize expands pwd.
   if {[catch { set _gitworktree $env(GIT_WORK_TREE) }]} {
       set _gitworktree [get_config core.worktree]
       if {$_gitworktree eq ""} {
           set _gitworktree [file normalize ./[git rev-parse --show-cdup]]
       }
   }
}

The  vsatisfies call probably doesn't handle '2.0.0.rc0' and the
fallback behaviour probably needs to normalise core.worktree

The _git_version variable has already been trimmed to remove such
suffixes so the version comparison here will be ok. 

I don't think that's true 'git rev-parse --show-toplevel' does the right
thing - if it's run.

It looks more likely
to be something to do with the .git being a file with a link being
mishandled. How did you setup this test repository with its link to a
parent?

It's just a git clone of the parent and a git submodule init. A subtle
thing to notice is that config.worktree is relative to $GIT_DIR. All the
configuration was done by git without any intervention from me.

Here's some other info that might help

  $ git --version
  git version 2.0.0.rc0

  $ cat .git
  gitdir: ../.git/modules/<repo>

  $ git rev-parse --git-dir
  /home/chris/src/<super>/.git/modules/<repo>

  $ git config core.worktree
  ../../../<repo>

Thanks,
Chris
