24.0.50; tramp hangs when process died |
|

Hi,
Using tramp to edit remote files creates some ssh processes.
When this process dies for some reasons (such ad IP change or network
outrage), the associated buffer is still alive and makes tramp hanging
when trying to reconnect the remote host.
This behavior happens every time I carry my laptop (in suspend to disk
or suspend to ram mode) from my home to my office (or the way back).
Here is a patch (for tramp-sh.el) to add a sentinel that kills the
process buffer when the process exit:
--- tramp-sh.el.o 2011-06-24 14:44:09.023169775 +0200
+++ tramp-sh.el 2011-06-24 14:52:57.383172776 +0200
@@ -4277,6 +4277,13 @@
(tramp-get-connection-buffer vec)
tramp-encoding-shell))))
+ ;; Kill buffer when process died.
+ (set-process-sentinel

+ (when (eq (process-status proc) 'exit)
+ (kill-buffer (process-buffer proc)))

(tramp-message
vec 6 "%s" (mapconcat 'identity (process-command p) " "))
Hope this doesn't break anything.
Cheers.
