I can reproduce; IIUC the salient point is setting start-point to a
local revision when calling git checkout, by opposition to
e.g. origin/master.  Continuing off of your recipe:

$ git branch --set-upstream-to origin/master

Then M-x vc-dir works again.

IIUC, to display

  Remote     : https://git.savannah.gnu.org/git/emacs.git

vc-git-dir-extra-headers runs

1. git config branch.vc-dir-bug.remote =E2=87=92 "."
2. (vc-git-repository-url "[=E2=80=A6 EMACS DIR =E2=80=A6]" ".")
    1. git config remote...url =E2=87=92 error

git-config(1) says that branch.<name>.remote is "." when <name> is
tracking a local branch, whereas branch.<name>.merge points to the local
branch 'git pull' will resync with.  Wonder what TRT would be for the
purposes of vc-dir?

(1) Drop the "Remote" header: the current branch is not sync'd with a
remote branch, after all.

(2) Print "Remote: https://git.savannah.gnu.org/git/emacs.git" by making
vc-git-repository-url fall back to remote.origin.url when remote-name is
".".

(3) Print "Remote: master" by making vc-git-dir-extra-headers fall back
to branch.<name>.merge when .remote is ".".

(4) Make vc-git-dir-extra-headers fall back to
branch.<branch.<name>.merge>.remote.  In our example, that would yield
"Remote: https://git.savannah.gnu.org/git/emacs.git", but in general
that seems unreliable, since that remote could be "." as well, and
nothing prevents cycles AFAIU.

IMO (3) would be the most robust, though maybe confusing (calling a
local branch "remote"); (2) makes sense as well since
vc-git-repository-url already falls back to remote.origin.url when
remote-name is nil.

(1) sounds trivially "robust" and "not too incorrect", but maybe not the
most helpful.  (4) is under-specified and I'm not convinced it is
possible to make it generally useful.


Hope I've not mis-diagnosed the problem; apologies for the noise if so.

Eli> Thanks, but I think we'd appreciate a reproducible recipe for this:

This worked for me:

$ cd ~/Emacs/trunk
# This is my Emacs git repository
$ git checkout --track -b vc-dir-bug master
branch 'vc-dir-bug' set up to track 'master'.
Switched to a new branch 'vc-dir-bug'


Now invoke vc-dir on that directory.

Thanks, but I think we'd appreciate a reproducible recipe for this:
how can one create a Git repository which can be used to reproduce

I use vc-dir frequently.

When I check out one particular branch of my gdb repository, vc-dir
fails with this error:

vc-do-command: Failed (status 2): git --no-pager remote get-url . .

The only thing that might be peculiar about this branch is that it uses
another local branch as its tracking branch.

If I check out other branches in this repository -- ones that track
remote branches -- vc-dir works again.
