23.1; Problem with vc-next-action |
|
Date: |
Sun, 9 May 2010 18:52:28 +0100 |
Attempting to run C-x v v from a *vc-dir* buffer (in this case, for a
git repository), I was prompted with:
<FILE> is edited but read-only; make it writable and continue?(y or n)
When I press “y” I get the error:
Wrong type argument: number-or-marker-p, nil
There are at least three things wrong here:
1. In the prompt mentioned above, “(y or n)” needs a space before it.
2. The file that was diagnosed as read only was not read-only: it had
perms -rw-r-----, and emacs was running under the owner’s uid.
3. The error mentioned above. I get the following backtrace:
Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p nil)
logior(nil 128)
vc-next-action(nil)
call-interactively(vc-next-action nil nil)

The only explanation I can come up with for 2 and 3 is that you somehow
lost execute permissions on the directory. Anyway, I made it give a more
explicit error if it fails to make the file writable. The user will have
to sort out whatever the problem is in such a case.
