;;; Commentary:
|
|
|
|
;; Some of the tests require access to a remote host files. Since
|
|
;; this could be problematic, a mock-up connection method "mock" is
|
|
;; used. Emulating a remote connection, it simply calls "sh -i".
|
|
;; Tramp's file name handlers still run, so this test is sufficient
|
|
;; except for connection establishing.
|
|
|
|
;; If you want to test a real Tramp connection, set
|
|
;; $REMOTE_TEMPORARY_FILE_DIRECTORY to a suitable value in order to
|
|
;; overwrite the default value. If you want to skip tests accessing a
|
|
;; remote host, set this environment variable to "/dev/null" or
|
|
;; whatever is appropriate on your system.
|
|
|
|
;; For the remote file-notify library, Tramp checks for the existence
|
|
;; of a respective command. The first command found is used. In
|
|
;; order to use a dedicated one, the environment variable
|
|
;; $REMOTE_FILE_NOTIFY_LIBRARY shall be set, possible values are
|
|
;; "inotifywait", "gio-monitor" and "gvfs-monitor-dir".
|
|
|
|
;; Local file-notify libraries are auto-detected during Emacs
|
|
;; configuration. This can be changed with a respective configuration
|
|
;; argument, like
|
|
;;
|
|
;; --with-file-notification=inotify
|
|
;; --with-file-notification=kqueue
|
|
;; --with-file-notification=gfile
|
|
;; --with-file-notification=w32
|
|
|
|
;; A whole test run can be performed calling the command `auto-revert-test-all'.
