| 4986 | ;; likely to produce long command lines, and some shells choke on | |
| 4987 | ;; long command lines. | |
| 4988 | ;; * Make it work for different encodings, and for different file name | |
| 4989 | ;; encodings, too. (Daniel Pittman) | |
| 4990 | ;; * Don't search for perl5 and perl. Instead, only search for perl and | |
| 4991 | ;; then look if it's the right version (with `perl -v'). | |
| 4992 | ;; * When editing a remote CVS controlled file as a different user, VC | |
| 4993 | ;; gets confused about the file locking status. Try to find out why | |
| 4994 | ;; the workaround doesn't work. | |
| 4995 | ;; * Allow out-of-band methods as _last_ multi-hop. Open a connection | |
| 4996 | ;; until the last but one hop via `start-file-process'. Apply it | |
| 4997 | ;; also for ftp and smb. | |
| 4998 | ;; * WIBNI if we had a command "trampclient"? If I was editing in | |
| 4999 | ;; some shell with root priviledges, it would be nice if I could | |
| 5000 | ;; just call | |
| 5001 | ;; trampclient filename.c | |
| 5002 | ;; as an editor, and the _current_ shell would connect to an Emacs | |
| 5003 | ;; server and would be used in an existing non-priviledged Emacs | |
| 5004 | ;; session for doing the editing in question. | |
| 5005 | ;; That way, I need not tell Emacs my password again and be afraid | |
| 5006 | ;; that it makes it into core dumps or other ugly stuff (I had Emacs | |
| 5007 | ;; once display a just typed password in the context of a keyboard | |
| 5008 | ;; sequence prompt for a question immediately following in a shell | |
| 5009 | ;; script run within Emacs -- nasty). | |
| 5010 | ;; And if I have some ssh session running to a different computer, | |
| 5011 | ;; having the possibility of passing a local file there to a local | |
| 5012 | ;; Emacs session (in case I can arrange for a connection back) would | |
| 5013 | ;; be nice. | |
| 5014 | ;; Likely the corresponding Tramp server should not allow the | |
| 5015 | ;; equivalent of the emacsclient -eval option in order to make this | |
| 5016 | ;; reasonably unproblematic. And maybe trampclient should have some | |
| 5017 | ;; way of passing credentials, like by using an SSL socket or | |
| 5018 | ;; something. (David Kastrup) | |
| 5019 | ;; * Reconnect directly to a compliant shell without first going | |
| 5020 | ;; through the user's default shell. (Pete Forman) | |
| 5021 | ;; * How can I interrupt the remote process with a signal | |
| 5022 | ;; (interrupt-process seems not to work)? (Markus Triska) | |
| 5023 | ;; * Avoid the local shell entirely for starting remote processes. If | |
| 5024 | ;; so, I think even a signal, when delivered directly to the local | |
| 5025 | ;; SSH instance, would correctly be propagated to the remote process | |
| 5026 | ;; automatically; possibly SSH would have to be started with | |
| 5027 | ;; "-t". (Markus Triska) | |
| 5028 | ;; * It makes me wonder if tramp couldn't fall back to ssh when scp | |
| 5029 | ;; isn't on the remote host. (Mark A. Hershberger) | |
| 5030 | ;; * Use lsh instead of ssh. (Alfred M. Szmidt) | |
| 5031 | ;; * Optimize out-of-band copying, when both methods are scp-like (not | |
| 5032 | ;; rsync). | |
| 5033 | ;; * Keep a second connection open for out-of-band methods like scp or | |
| 5034 | ;; rsync. | |
| 5035 | ;; * Try telnet+curl as new method. It might be useful for busybox, | |
| 5036 | ;; without built-in uuencode/uudecode. | |
