Dired move of directory to remote with TRAMP (ssh) fails |
|
Date: |

Moving a directory from the local system to a remote ssh tramp directory fails
To reproduce:
mkdir test_dired_copy/a -p
cd test_dired_copy
emacs -Q --eval '(dired ".")'
In dired, execute `dired-do-rename' (kbd "R") on the `a' directory and
select a remote (writable) destination using the Tramp ssh method, for
instance:
/ssh:address@hidden:/path/on/remote/ .
(I've tried to consistently replace the details of the remote with
dummy values (the username with `username', the hostname with
`hostname' and the path of the directory into which `a' should be
copied with `/path/on/remote/'). I'm not mis-typing the paths when
testing — for instance C-x d /ssh:address@hidden:/path/on/remote/
works as expected.)
Expected result:
The directory `a' is moved ("renamed") into the remote destination.
Actual result:
The directory `a' remains in test_dired_copy, does not appear on the
remote system and the following error message is displayed:
Renaming /home/adam/test_dired_copy/a to
/ssh:address@hidden:/path/on/remote/a...failed
Move ‘/home/adam/test_dired_copy/a’ to
‘/ssh:address@hidden:/path/on/remote/a’ failed:
(file-error Read error Is a directory /home/adam/test_dired_copy/a)
* What also does not work (I assume this is related, but I may be
wrong):
** Moving a directory from a remote ssh tramp directory to the local
system
mkdir -p test_dired_copy
emacs -Q
M-x mkdir /ssh:address@hidden:/path/on/remote/b
M-x dired /ssh:address@hidden:/path/on/remote/
In dired, execute `dired-do-rename' (kbd "R") on the `b' directory and
select a local destination (for instance /home/adam/test_dired_copy/
).
*** Expected result:
(1. The remote directory b is created.)
2. The remote directory b is moved to the local destination.
*** Actual result:
(1. The remote directory b is created, as expected.)
2. The remote directory b is not moved and the following error message
is displayed:
Renaming /ssh:address@hidden:/path/on/remote/b to
/home/adam/test_dired_copy/b...failed
Move ‘/ssh:address@hidden:/path/on/remote/b’ to
‘/home/adam/test_dired_copy/b’ failed:
(file-error Encoding remote file failed)
* What does work
** Copying a directory from the local system to a remote one and
vice-versa
(i.e. exactly as above, but using `dired-do-copy' ("C") rather than
`dired-do-rename', in either direction)
** Moving a file from the local to the remote system and vice-versa
(i.e. instead of using `dired-do-rename' on a directory, use it on a
"normal" file)
** Moving a directory from one location on the remote to another on
the same remote (but NOT one on a different remote — that results
in the same error as trying to move from the remote to the local system).
** Moving a directory on the local system, but to a location managed
with the Tramp sudo method.
(Moving from, say `/home/adam/test1/a' to `/sudo::/home/adam/test2/').
This strongly suggests that the issue is not with Tramp, as such, but
with the interaction with the backend.
The bug is present on all versions of emacs that I've tested (from
23.4, through 24.5 and 25.1 to master
(94281c9a1cc0f756841fdc9b266657853df94a29) and emacs-26
(2f7163fb72e764d2df046a4d816e1e0b81e41d18)). All the systems tested
(local and remote) were Ubuntu 16.04.3.
Note that this was previously misreported as part of #28519.
Obviously, since copying a directory and then deleting it from the
source, both work, one can easily circumvent the bug when using dired,
if one remembers.
Thanks for reading the bug and working on emacs!

Wow, that was fast!
The bug is indeed fixed.
(Moving directories in Dired with Tramp now works both from and
to remote locations. Loading TRAMP's emacs-26 files from emacs
24.5 or 25.1 also resolves the issue in these versions of emacs.)
Thank you very much and best regards,
Adam
