bug#4350: tramp "sudo" and "su" broken: `\stat -c '(("%N") [...]' returns with error

[Teemu Likonen]

The current (Sat, 05 Sep 2009 16:26:16 +0000) Emacs trunk repository has
broken tramp /su and /sudo protocol. To reproduce:

    $ emacs -Q

    C-x C-f /su::/root/test.txt

    [Type password]

The result:

    tramp-error: `\stat -c '(("%N") %h %u %g %X.0 %Y.0 %Z.0 %s.0 "%A" t
    %i.0 -1)' /root/test.txt' returns with error

Could you, please, set tramp-verbose to 6, and show Tramp's debug
buffer?

Thanks, and best regards, Michael.

Thanks!

The problem is related to one of the outstanding optimization patches of
Julian. We are waiting for arrival of his papers at FSF.

More precisely, I've committed already my part, and I've overseen the
dependency. Sorry.

Since the patch does not modify more than 15 lines (the rest are just
changed indented lines), I've committed it as tiny patch. The problem
shall be fixed now.

Best regards, Michael.

I tested it very quickly but looks like it's indeed fixed. Thanks.

The current (Sat, 05 Sep 2009 16:26:16 +0000) Emacs trunk repository has

    $ emacs -Q

OK, I mark it as fixed.
