bug#779: Tramp saves old locations, tries to re-open them on launch

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

I open one or more files via tramp on a remote machine. I then close
down Emacs. I do not save remote files in the desktop.

On re-lanching Emacs, it logs into the machines via tramp. This is a
waste of time if none of the files are in the desktop. Worse, if
somehow tramp tries to log in to a user:machine where I don't have the
password, Emacs ceases to process .emacs. Similarly if it tries to log
into an account on a machine which is shut down or otherwise
unavailable.

If there is a variable "tramp.*" that controls this behavior, I don't
see it.

Thank you.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/share/emacs/22.1/etc/DEBUG for instructions.

No crash.

Tramp does not reconnect to files on its own. You can check this if
you call "emacs -Q".

Likely you have enabled recentf or another package like this. Could
you, please, check it in your .emacs?

It's the first entry in "Minor modes in effect:" in the original report.

There seems to be a fix for this in the trunk recentf-keep:

    Remote files are checked for readability only in case a connection
    is established to that remote system, otherwise they are kept in
    the recent list without checking their readability.

Yep. Charles did already confirm by a PM, that the problem was caused by this.

Right, but this doesn't work for Emacs 22 (which is used here). Instead
of, recentf-keep recommends there

    A predicate is a function that is passed a filename to check and that
    must return non-nil to keep it.  For example, you can add the
    `file-remote-p' predicate in front of this list to keep remote file
    names in the recent list without checking their readability through a
    remote access.

After all, I guess we can tag this record as "notabug".

Best regards, Michael.

I'd go for "fixed 779 23.0.60" personally.

I don't object (I wrote the fix last year :-)

However, it is a more philosophical question, whether it is a "bug fix"
or an "improvement of convenience".

Best regards, Michael.

Let's have both. :)

I'd rather not backport this into the branch at this stage of the
pretest.  However, this change ought to have been documented in NEWS on
the trunk.  Michael, could you write a NEWS entry?

Thanks.
