Re: git gui error with relocated repository

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

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
