37 ;;; Description:
|
|
|
38 ;;;
|
|
|
39 ;;; This package attempts to make accessing files and directories using FTP
|
|
|
40 ;;; from within GNU Emacs as simple and transparent as possible. A subset of
|
|
|
41 ;;; the common file-handling routines are extended to interact with FTP.
|
|
|
42
|
|
|
43 ;;; Installation:
|
|
|
44 ;;;
|
|
|
45 ;;; Byte-compile ange-ftp.el to ange-ftp.elc and put them both in a directory
|
|
|
46 ;;; on your load-path. Load the package from your .emacs file with:
|
|
|
47 ;;;
|
|
|
48 ;;; (require 'ange-ftp).
|
|
|
49 ;;;
|
|
|
50 ;;; ange-ftp can't sensibly be auto-loaded; you are either using it, or you
|
|
|
51 ;;; ain't.
|
|
|
52
|
|
|
53 ;;; Usage:
|
|
|
54 ;;;
|
|
|
55 ;;; Some of the common GNU Emacs file-handling operations have been made
|
|
|
56 ;;; FTP-smart. If one of these routines is given a filename that matches
|
|
|
57 ;;; '/user@host:path' then it will spawn an FTP process connecting to machine
|
|
|
58 ;;; 'host' as account 'user' and perform its operation on the file 'path'.
|
|
|
59 ;;;
|
|
|
60 ;;; For example: if find-file is given a filename of:
|
|
|
61 ;;;
|
|
|
62 ;;; /ange@anorman:/tmp/notes
|
|
|
63 ;;;
|
|
|
64 ;;; then ange-ftp will spawn an FTP process, connect to the host 'anorman' as
|
|
|
65 ;;; user 'ange', get the file '/tmp/notes' and pop up a buffer containing the
|
|
|
66 ;;; contents of that file as if it were on the local filesystem. If ange-ftp
|
|
|
67 ;;; needed a password to connect then it would prompt the user in the
|
|
|
68 ;;; minibuffer.
|
|
|
69
|
|
|
70 ;;; Extended filename syntax:
|
|
|
71 ;;;
|
|
|
72 ;;; The default extended filename syntax is '/user@host:path', where the
|
|
|
73 ;;; 'user@' part may be omitted. This syntax can be customised to a certain
|
|
|
74 ;;; extent by changing ange-ftp-path-format. There are limitations.
|
|
|
75 ;;;
|
|
|
76 ;;; If the user part is omitted then ange-ftp will generate a default user
|
|
|
77 ;;; instead whose value depends on the variable ange-ftp-default-user.
|
|
|
78
|
|
|
79 ;;; Passwords:
|
|
|
80 ;;;
|
|
|
81 ;;; A password is required for each host / user pair. This will be prompted
|
|
|
82 ;;; for when needed, unless already set by calling ange-ftp-set-passwd, or
|
|
|
83 ;;; specified in a *valid* ~/.netrc file.
|
|
|
84
|
|
|
85 ;;; Passwords for user "anonymous":
|
|
|
86 ;;;
|
|
|
87 ;;; Passwords for the user "anonymous" (or "ftp") are handled specially. The
|
|
|
88 ;;; variable ange-ftp-generate-anonymous-password controls what happens: if
|
|
|
89 ;;; the value of this variable is a string, then this is used as the password;
|
|
|
90 ;;; if non-nil, then a password is created from the name of the user and the
|
|
|
91 ;;; hostname of the machine on which GNU Emacs is running; if nil (the
|
|
|
92 ;;; default) then the user is prompted for a password as normal.
|
|
|
93
|
|
|
94 ;;; "Dumb" UNIX hosts:
|
|
|
95 ;;;
|
|
|
96 ;;; The FTP servers on some UNIX machines have problems if the 'ls' command is
|
|
|
97 ;;; used.
|
|
|
98 ;;;
|
|
|
99 ;;; The routine ange-ftp-add-dumb-unix-host can be called to tell ange-ftp to
|
|
|
100 ;;; limit itself to the DIR command and not 'ls' for a given UNIX host. Note
|
|
|
101 ;;; that this change will take effect for the current GNU Emacs session only.
|
|
|
102 ;;; See below for a discussion of non-UNIX hosts. If a large number of
|
|
|
103 ;;; machines with similar hostnames have this problem then it is easier to set
|
|
|
104 ;;; the value of ange-ftp-dumb-unix-host-regexp in your .emacs file. ange-ftp
|
|
|
105 ;;; is unable to automatically recognize dumb unix hosts.
|
|
|
106
|
|
|
107 ;;; File name completion:
|
|
|
108 ;;;
|
|
|
109 ;;; Full file-name completion is supported on UNIX, VMS, CMS, and MTS hosts.
|
|
|
110 ;;; To do filename completion, ange-ftp needs a listing from the remote host.
|
|
|
111 ;;; Therefore, for very slow connections, it might not save any time.
|
|
|
112
|
|
|
113 ;;; FTP processes:
|
|
|
114 ;;;
|
|
|
115 ;;; When ange-ftp starts up an FTP process, it leaves it running for speed
|
|
|
116 ;;; purposes. Some FTP servers will close the connection after a period of
|
|
|
117 ;;; time, but ange-ftp should be able to quietly reconnect the next time that
|
|
|
118 ;;; the process is needed.
|
|
|
119 ;;;
|
|
|
120 ;;; The FTP process will be killed should the associated "*ftp user@host*"
|
|
|
121 ;;; buffer be deleted. This should not cause ange-ftp any grief.
|
|
|
122
|
|
|
123 ;;; Binary file transfers:
|
|
|
124 ;;;
|
|
|
125 ;;; By default ange-ftp will transfer files in ASCII mode. If a file being
|
|
|
126 ;;; transferred matches the value of ange-ftp-binary-file-name-regexp then the
|
|
|
127 ;;; FTP process will be toggled into BINARY mode before the transfer and back
|
|
|
128 ;;; to ASCII mode after the transfer.
|
|
|
129
|
|
|
130 ;;; Account passwords:
|
|
|
131 ;;;
|
|
|
132 ;;; Some FTP servers require an additional password which is sent by the
|
|
|
133 ;;; ACCOUNT command. ange-ftp partially supports this by allowing the user to
|
|
|
134 ;;; specify an account password by either calling ange-ftp-set-account, or by
|
|
|
135 ;;; specifying an account token in the .netrc file. If the account password
|
|
|
136 ;;; is set by either of these methods then ange-ftp will issue an ACCOUNT
|
|
|
137 ;;; command upon starting the FTP process.
|
|
|
138
|
|
|
139 ;;; Preloading:
|
|
|
140 ;;;
|
|
|
141 ;;; ange-ftp can be preloaded, but must be put in the site-init.el file and
|
|
|
142 ;;; not the site-load.el file in order for the documentation strings for the
|
|
|
143 ;;; functions being overloaded to be available.
|
|
|
144
|
|
|
145 ;;; Status reports:
|
|
|
146 ;;;
|
|
|
147 ;;; Most ange-ftp commands that talk to the FTP process output a status
|
|
|
148 ;;; message on what they are doing. In addition, ange-ftp can take advantage
|
|
|
149 ;;; of the FTP client's HASH command to display the status of transferring
|
|
|
150 ;;; files and listing directories. See the documentation for the variables
|
|
|
151 ;;; ange-ftp-{ascii,binary}-hash-mark-size, ange-ftp-send-hash and
|
|
|
152 ;;; ange-ftp-process-verbose for more details.
|
|
|
153
|
|
|
154 ;;; Gateways:
|
|
|
155 ;;;
|
|
|
156 ;;; Sometimes it is neccessary for the FTP process to be run on a different
|
|
|
157 ;;; machine than the machine running GNU Emacs. This can happen when the
|
|
|
158 ;;; local machine has restrictions on what hosts it can access.
|
|
|
159 ;;;
|
|
|
160 ;;; ange-ftp has support for running the ftp process on a different (gateway)
|
|
|
161 ;;; machine. The way it works is as follows:
|
|
|
162 ;;;
|
|
|
163 ;;; 1) Set the variable 'ange-ftp-gateway-host' to the name of a machine
|
|
|
164 ;;; that doesn't have the access restrictions.
|
|
|
165 ;;;
|
|
|
166 ;;; 2) Set the variable 'ange-ftp-local-host-regexp' to a regular expression
|
|
|
167 ;;; that matches hosts that can be contacted from running a local ftp
|
|
|
168 ;;; process, but fails to match hosts that can't be accessed locally. For
|
|
|
169 ;;; example:
|
|
|
170 ;;;
|
|
|
171 ;;; "\\.hp\\.com$\\|^[^.]*$"
|
|
|
172 ;;;
|
|
|
173 ;;; will match all hosts that are in the .hp.com domain, or don't have an
|
|
|
174 ;;; explicit domain in their name, but will fail to match hosts with
|
|
|
175 ;;; explicit domains or that are specified by their ip address.
|
|
|
176 ;;;
|
|
|
177 ;;; 3) Using NFS and symlinks, make sure that there is a shared directory with
|
|
|
178 ;;; the *same* name between the local machine and the gateway machine.
|
|
|
179 ;;; This directory is neccessary for temporary files created by ange-ftp.
|
|
|
180 ;;;
|
|
|
181 ;;; 4) Set the variable 'ange-ftp-gateway-tmp-name-template' to the name of
|
|
|
182 ;;; this directory plus an identifying filename prefix. For example:
|
|
|
183 ;;;
|
|
|
184 ;;; "/nfs/hplose/ange/ange-ftp"
|
|
|
185 ;;;
|
|
|
186 ;;; where /nfs/hplose/ange is a directory that is shared between the
|
|
|
187 ;;; gateway machine and the local machine.
|
|
|
188 ;;;
|
|
|
189 ;;; The simplest way of getting a ftp process running on the gateway machine
|
|
|
190 ;;; is if you can spawn a remote shell using either 'rsh' or 'remsh'. If you
|
|
|
191 ;;; can't do this for some reason such as security then points 7 onwards will
|
|
|
192 ;;; discuss an alternative approach.
|
|
|
193 ;;;
|
|
|
194 ;;; 5) Set the variable ange-ftp-gateway-program to the name of the remote
|
|
|
195 ;;; shell process such as 'remsh' or 'rsh' if the default isn't correct.
|
|
|
196 ;;;
|
|
|
197 ;;; 6) Set the variable ange-ftp-gateway-program-interactive to nil if it
|
|
|
198 ;;; isn't already. This tells ange-ftp that you are using a remote shell
|
|
|
199 ;;; rather than logging in using telnet or rlogin.
|
|
|
200 ;;;
|
|
|
201 ;;; That should be all you need to allow ange-ftp to spawn a ftp process on
|
|
|
202 ;;; the gateway machine. If you have to use telnet or rlogin to get to the
|
|
|
203 ;;; gateway machine then follow the instructions below.
|
|
|
204 ;;;
|
|
|
205 ;;; 7) Set the variable ange-ftp-gateway-program to the name of the program
|
|
|
206 ;;; that lets you log onto the gateway machine. This may be something like
|
|
|
207 ;;; telnet or rlogin.
|
|
|
208 ;;;
|
|
|
209 ;;; 8) Set the variable ange-ftp-gateway-prompt-pattern to a regular
|
|
|
210 ;;; expression that matches the prompt you get when you login to the
|
|
|
211 ;;; gateway machine. Be very specific here; this regexp must not match
|
|
|
212 ;;; *anything* in your login banner except this prompt.
|
|
|
213 ;;; shell-prompt-pattern is far too general as it appears to match some
|
|
|
214 ;;; login banners from Sun machines. For example:
|
|
|
215 ;;;
|
|
|
216 ;;; "^$*$ *"
|
|
|
217 ;;;
|
|
|
218 ;;; 9) Set the variable ange-ftp-gateway-program-interactive to 't' to let
|
|
|
219 ;;; ange-ftp know that it has to "hand-hold" the login to the gateway
|
|
|
220 ;;; machine.
|
|
|
221 ;;;
|
|
|
222 ;;; 10) Set the variable ange-ftp-gateway-setup-term-command to a UNIX command
|
|
|
223 ;;; that will put the pty connected to the gateway machine into a
|
|
|
224 ;;; no-echoing mode, and will strip off carriage-returns from output from
|
|
|
225 ;;; the gateway machine. For example:
|
|
|
226 ;;;
|
|
|
227 ;;; "stty -onlcr -echo"
|
|
|
228 ;;;
|
|
|
229 ;;; will work on HP-UX machines, whereas:
|
|
|
230 ;;;
|
|
|
231 ;;; "stty -echo nl"
|
|
|
232 ;;;
|
|
|
233 ;;; appears to work for some Sun machines.
|
|
|
234 ;;;
|
|
|
235 ;;; That's all there is to it.
|
|
|
236
|
|
|
237 ;;; Smart gateways:
|
|
|
238 ;;;
|
|
|
239 ;;; If you have a "smart" ftp program that allows you to issue commands like
|
|
|
240 ;;; "USER foo@bar" which do nice proxy things, then look at the variables
|
|
|
241 ;;; ange-ftp-smart-gateway and ange-ftp-smart-gateway-port.
|
|
|
242
|
|
|
243 ;;; Tips for using ange-ftp:
|
|
|
244 ;;;
|
|
|
245 ;;; 1. For dired to work on a host which marks symlinks with a trailing @ in
|
|
|
246 ;;; an ls -alF listing, you need to (setq dired-ls-F-marks-symlinks t).
|
|
|
247 ;;; Most UNIX systems do not do this, but ULTRIX does. If you think that
|
|
|
248 ;;; there is a chance you might connect to an ULTRIX machine (such as
|
|
|
249 ;;; prep.ai.mit.edu), then set this variable accordingly. This will have
|
|
|
250 ;;; the side effect that dired will have problems with symlinks whose names
|
|
|
251 ;;; end in an @. If you get youself into this situation then editing
|
|
|
252 ;;; dired's ls-switches to remove "F", will temporarily fix things.
|
|
|
253 ;;;
|
|
|
254 ;;; 2. If you know that you are connecting to a certain non-UNIX machine
|
|
|
255 ;;; frequently, and ange-ftp seems to be unable to guess its host-type,
|
|
|
256 ;;; then setting the appropriate host-type regexp
|
|
|
257 ;;; (ange-ftp-vms-host-regexp, ange-ftp-mts-host-regexp, or
|
|
|
258 ;;; ange-ftp-cms-host-regexp) accordingly should help. Also, please report
|
|
|
259 ;;; ange-ftp's inability to recognize the host-type as a bug.
|
|
|
260 ;;;
|
|
|
261 ;;; 3. For slow connections, you might get "listing unreadable" error
|
|
|
262 ;;; messages, or get an empty buffer for a file that you know has something
|
|
|
263 ;;; in it. The solution is to increase the value of ange-ftp-retry-time.
|
|
|
264 ;;; Its default value is 5 which is plenty for reasonable connections.
|
|
|
265 ;;; However, for some transatlantic connections I set this to 20.
|
|
|
266 ;;;
|
|
|
267 ;;; 4. Beware of compressing files on non-UNIX hosts. Ange-ftp will do it by
|
|
|
268 ;;; copying the file to the local machine, compressing it there, and then
|
|
|
269 ;;; sending it back. Binary file transfers between machines of different
|
|
|
270 ;;; architectures can be a risky business. Test things out first on some
|
|
|
271 ;;; test files. See "Bugs" below. Also, note that ange-ftp copies files by
|
|
|
272 ;;; moving them through the local machine. Again, be careful when doing
|
|
|
273 ;;; this with binary files on non-Unix machines.
|
|
|
274 ;;;
|
|
|
275 ;;; 5. Beware that dired over ftp will use your setting of dired-no-confirm
|
|
|
276 ;;; (list of dired commands for which confirmation is not asked). You
|
|
|
277 ;;; might want to reconsider your setting of this variable, because you
|
|
|
278 ;;; might want confirmation for more commands on remote direds than on
|
|
|
279 ;;; local direds. For example, I strongly recommend that you not include
|
|
|
280 ;;; compress and uncompress in this list. If there is enough demand it
|
|
|
281 ;;; might be a good idea to have an alist ange-ftp-dired-no-confirm of
|
|
|
282 ;;; pairs ( TYPE . LIST ), where TYPE is an operating system type and LIST
|
|
|
283 ;;; is a list of commands for which confirmation would be suppressed. Then
|
|
|
284 ;;; remote dired listings would take their (buffer-local) value of
|
|
|
285 ;;; dired-no-confirm from this alist. Who votes for this?

|
|
290
|
|
|
291 ;;; VMS support:
|
|
|
292 ;;;
|
|
|
293 ;;; Ange-ftp has full support for VMS hosts, including tree dired support. It
|
|
|
294 ;;; should be able to automatically recognize any VMS machine. However, if it
|
|
|
295 ;;; fails to do this, you can use the command ange-ftp-add-vms-host. As well,
|
|
|
296 ;;; you can set the variable ange-ftp-vms-host-regexp in your .emacs file. We
|
|
|
297 ;;; would be grateful if you would report any failures to automatically
|
|
|
298 ;;; recognize a VMS host as a bug.
|
|
|
299 ;;;
|
|
|
300 ;;; Filename Syntax:
|
|
|
301 ;;;
|
|
|
302 ;;; For ease of *implementation*, the user enters the VMS filename syntax in a
|
|
|
303 ;;; UNIX-y way. For example:
|
|
|
304 ;;; PUB$:[ANONYMOUS.SDSCPUB.NEXT]README.TXT;1
|
|
|
305 ;;; would be entered as:
|
|
|
306 ;;; /PUB$$:/ANONYMOUS/SDSCPUB/NEXT/README.TXT;1
|
|
|
307 ;;; i.e. to log in as anonymous on ymir.claremont.edu and grab the file:
|
|
|
308 ;;; [.CSV.POLICY]RULES.MEM
|
|
|
309 ;;; you would type:
|
|
|
310 ;;; C-x C-f /anonymous@ymir.claremont.edu:CSV/POLICY/RULES.MEM
|
|
|
311 ;;;
|
|
|
312 ;;; A legal VMS filename is of the form: FILE.TYPE;##
|
|
|
313 ;;; where FILE can be up to 39 characters
|
|
|
314 ;;; TYPE can be up to 39 characters
|
|
|
315 ;;; ## is a version number (an integer between 1 and 32,767)
|
|
|
316 ;;; Valid characters in FILE and TYPE are A-Z 0-9 _ - $
|
|
|
317 ;;; $ cannot begin a filename, and - cannot be used as the first or last
|
|
|
318 ;;; character.
|
|
|
319 ;;;
|
|
|
320 ;;; Tips:
|
|
|
321 ;;; 1. Although VMS is not case sensitive, EMACS running under UNIX is.
|
|
|
322 ;;; Therefore, to access a VMS file, you must enter the filename with upper
|
|
|
323 ;;; case letters.
|
|
|
324 ;;; 2. To access the latest version of file under VMS, you use the filename
|
|
|
325 ;;; without the ";" and version number. You should always edit the latest
|
|
|
326 ;;; version of a file. If you want to edit an earlier version, copy it to a
|
|
|
327 ;;; new file first. This has nothing to do with ange-ftp, but is simply
|
|
|
328 ;;; good VMS operating practice. Therefore, to edit FILE.TXT;3 (say 3 is
|
|
|
329 ;;; latest version), do C-x C-f /ymir.claremont.edu:FILE.TXT. If you
|
|
|
330 ;;; inadvertently do C-x C-f /ymir.claremont.edu:FILE.TXT;3, you will find
|
|
|
331 ;;; that VMS will not allow you to save the file because it will refuse to
|
|
|
332 ;;; overwrite FILE.TXT;3, but instead will want to create FILE.TXT;4, and
|
|
|
333 ;;; attach the buffer to this file. To get out of this situation, M-x
|
|
|
334 ;;; write-file /ymir.claremont.edu:FILE.TXT will attach the buffer to
|
|
|
335 ;;; latest version of the file. For this reason, in tree dired "f"
|
|
|
336 ;;; (dired-find-file), always loads the file sans version, whereas "v",
|
|
|
337 ;;; (dired-view-file), always loads the explicit version number. The
|
|
|
338 ;;; reasoning being that it reasonable to view old versions of a file, but
|
|
|
339 ;;; not to edit them.
|
|
|
340 ;;; 3. EMACS has a feature in which it does environment variable substitution
|
|
|
341 ;;; in filenames. Therefore, to enter a $ in a filename, you must quote it
|
|
|
342 ;;; by typing $$. There is a bug in EMACS, in that it neglects to quote the
|
|
|
343 ;;; $'s in the default directory when it writes it in the minibuffer. You
|
|
|
344 ;;; must edit the minibuffer to quote the $'s manually. Hopefully, this bug
|
|
|
345 ;;; will be fixed in EMACS 19. If you use Sebastian Kremer's gmhist (V 4.26
|
|
|
346 ;;; or newer), you will not have this problem.
|
|
|
347
|
|
|
348 ;;; MTS support:
|
|
|
349 ;;;
|
|
|
350 ;;; Ange-ftp has full support, including tree dired support, for hosts running
|
|
|
351 ;;; the Michigan terminal system. It should be able to automatically
|
|
|
352 ;;; recognize any MTS machine. However, if it fails to do this, you can use
|
|
|
353 ;;; the command ange-ftp-add-mts-host. As well, you can set the variable
|
|
|
354 ;;; ange-ftp-mts-host-regexp in your .emacs file. We would be grateful if you
|
|
|
355 ;;; would report any failures to automatically recognize a MTS host as a bug.
|
|
|
356 ;;;
|
|
|
357 ;;; Filename syntax:
|
|
|
358 ;;;
|
|
|
359 ;;; MTS filenames are entered in a UNIX-y way. For example, if your account
|
|
|
360 ;;; was YYYY, the file FILE in the account XXXX: on mtsg.ubc.ca would be
|
|
|
361 ;;; entered as
|
|
|
362 ;;; /YYYY@mtsg.ubc.ca:/XXXX:/FILE
|
|
|
363 ;;; In other words, MTS accounts are treated as UNIX directories. Of course,
|
|
|
364 ;;; to access a file in another account, you must have access permission for
|
|
|
365 ;;; it. If FILE were in your own account, then you could enter it in a
|
|
|
366 ;;; relative path fashion as
|
|
|
367 ;;; /YYYY@mtsg.ubc.ca:FILE
|
|
|
368 ;;; MTS filenames can be up to 12 characters. Like UNIX, the structure of the
|
|
|
369 ;;; filename does not contain a TYPE (i.e. it can have as many "."'s as you
|
|
|
370 ;;; like.) MTS filenames are always in upper case, and hence be sure to enter
|
|
|
371 ;;; them as such! MTS is not case sensitive, but an EMACS running under UNIX
|
|
|
372 ;;; is.

|
374 ;;; CMS support:
|
|
|
375 ;;;
|
|
|
376 ;;; Ange-ftp has full support, including tree dired support, for hosts running
|
|
|
377 ;;; CMS. It should be able to automatically recognize any CMS machine.
|
|
|
378 ;;; However, if it fails to do this, you can use the command
|
|
|
379 ;;; ange-ftp-add-cms-host. As well, you can set the variable
|
|
|
380 ;;; ange-ftp-cms-host-regexp in your .emacs file. We would be grateful if you
|
|
|
381 ;;; would report any failures to automatically recognize a CMS host as a bug.
|
|
|
382 ;;;
|
|
|
383 ;;; Filename syntax:
|
|
|
384 ;;;
|
|
|
385 ;;; CMS filenames are entered in a UNIX-y way. In otherwords, minidisks are
|
|
|
386 ;;; treated as UNIX directories. For example to access the file READ.ME in
|
|
|
387 ;;; minidisk *.311 on cuvmb.cc.columbia.edu, you would enter
|
|
|
388 ;;; /anonymous@cuvmb.cc.columbia.edu:/*.311/READ.ME
|
|
|
389 ;;; If *.301 is the default minidisk for this account, you could access
|
|
|
390 ;;; FOO.BAR on this minidisk as
|
|
|
391 ;;; /anonymous@cuvmb.cc.columbia.edu:FOO.BAR
|
|
|
392 ;;; CMS filenames are of the form FILE.TYPE, where both FILE and TYPE can be
|
|
|
393 ;;; up to 8 characters. Again, beware that CMS filenames are always upper
|
|
|
394 ;;; case, and hence must be entered as such.
|
|
|
395 ;;;
|
|
|
396 ;;; Tips:
|
|
|
397 ;;; 1. CMS machines, with the exception of anonymous accounts, nearly always
|
|
|
398 ;;; need an account password. To have ange-ftp send an account password,
|
|
|
399 ;;; you can either include it in your .netrc file, or use
|
|
|
400 ;;; ange-ftp-set-account.
|
|
|
401 ;;; 2. Ange-ftp cannot send "write passwords" for a minidisk. Hopefully, we
|
|
|
402 ;;; can fix this.
|
|
|
403 ;;;
|
|
|
404 ;;; ------------------------------------------------------------------
|
|
|
405 ;;; Bugs:
|
|
|
406 ;;; ------------------------------------------------------------------
|
|
|
407 ;;;
|
|
|
408 ;;; 1. Umask problems:
|
|
|
409 ;;; Be warned that files created by using ange-ftp will take account of the
|
|
|
410 ;;; umask of the ftp daemon process rather than the umask of the creating
|
|
|
411 ;;; user. This is particulary important when logging in as the root user.
|
|
|
412 ;;; The way that I tighten up the ftp daemon's umask under HP-UX is to make
|
|
|
413 ;;; sure that the umask is changed to 027 before I spawn /etc/inetd. I
|
|
|
414 ;;; suspect that there is something similar on other systems.
|
|
|
415 ;;;
|
|
|
416 ;;; 2. Some combinations of FTP clients and servers break and get out of sync
|
|
|
417 ;;; when asked to list a non-existent directory. Some of the ai.mit.edu
|
|
|
418 ;;; machines cause this problem for some FTP clients. Using
|
|
|
419 ;;; ange-ftp-kill-process can be used to restart the ftp process, which
|
|
|
420 ;;; should get things back in synch.
|
|
|
421 ;;;
|
|
|
422 ;;; 3. Ange-ftp does not check to make sure that when creating a new file,
|
|
|
423 ;;; you provide a valid filename for the remote operating system.
|
|
|
424 ;;; If you do not, then the remote FTP server will most likely
|
|
|
425 ;;; translate your filename in some way. This may cause ange-ftp to
|
|
|
426 ;;; get confused about what exactly is the name of the file. The
|
|
|
427 ;;; most common causes of this are using lower case filenames on systems
|
|
|
428 ;;; which support only upper case, and using filenames which are too
|
|
|
429 ;;; long.
|
|
|
430 ;;;
|
|
|
431 ;;; 4. Null (blank) passwords confuse both ange-ftp and some FTP daemons.
|
|
|
432 ;;;
|
|
|
433 ;;; 5. Ange-ftp likes to use pty's to talk to its FTP processes. If GNU Emacs
|
|
|
434 ;;; for some reason creates a FTP process that only talks via pipes then
|
|
|
435 ;;; ange-ftp won't be getting the information it requires at the time that
|
|
|
436 ;;; it wants it since pipes flush at different times to pty's. One
|
|
|
437 ;;; disgusting way around this problem is to talk to the FTP process via
|
|
|
438 ;;; rlogin which does the 'right' things with pty's.
|
|
|
439 ;;;
|
|
|
440 ;;; 6. For CMS support, we send too many cd's. Since cd's are cheap, I haven't
|
|
|
441 ;;; worried about this too much. Eventually, we should have some caching
|
|
|
442 ;;; of the current minidisk.
|
|
|
443 ;;;
|
|
|
444 ;;; 7. Some CMS machines do not assign a default minidisk when you ftp them as
|
|
|
445 ;;; anonymous. It is then necessary to guess a valid minidisk name, and cd
|
|
|
446 ;;; to it. This is (understandably) beyond ange-ftp.
|
|
|
447 ;;;
|
|
|
448 ;;; 8. Remote to remote copying of files on non-Unix machines can be risky.
|
|
|
449 ;;; Depending on the variable ange-ftp-binary-file-name-regexp, ange-ftp
|
|
|
450 ;;; will use binary mode for the copy. Between systems of different
|
|
|
451 ;;; architecture, this still may not be enough to guarantee the integrity
|
|
|
452 ;;; of binary files. Binary file transfers from VMS machines are
|
|
|
453 ;;; particularly problematical. Should ange-ftp-binary-file-name-regexp be
|
|
|
454 ;;; an alist of OS type, regexp pairs?
|
|
|
455 ;;;
|
|
|
456 ;;; 9. The code to do compression of files over ftp is not as careful as it
|
|
|
457 ;;; should be. It deletes the old remote version of the file, before
|
|
|
458 ;;; actually checking if the local to remote transfer of the compressed
|
|
|
459 ;;; file succeeds. Of course to delete the original version of the file
|
|
|
460 ;;; after transferring the compressed version back is also dangerous,
|
|
|
461 ;;; because some OS's have severe restrictions on the length of filenames,
|
|
|
462 ;;; and when the compressed version is copied back the "-Z" or ".Z" may be
|
|
|
463 ;;; truncated. Then, ange-ftp would delete the only remaining version of
|
|
|
464 ;;; the file. Maybe ange-ftp should make backups when it compresses files
|
|
|
465 ;;; (of course, the backup "~" could also be truncated off, sigh...).
|
|
|
466 ;;; Suggestions?
|
|
|
467 ;;;
|
|
|
468
|
|
|
469 ;;; 10. If a dir listing is attempted for an empty directory on (at least
|
|
|
470 ;;; some) VMS hosts, an ftp error is given. This is really an ftp bug, and
|
|
|
471 ;;; I don't know how to get ange-ftp work to around it.
|
|
|
472 ;;;
|
|
|
473 ;;; 11. Bombs on filenames that start with a space. Deals well with filenames
|
|
|
474 ;;; containing spaces, but beware that the remote ftpd may not like them
|
|
|
475 ;;; much.
|
|
|
476 ;;;
|
|
|
477 ;;; 12. No classic dired support for non-UNIX systems. Tree dired was enough.
|
|
|
478 ;;;
|
|
|
479 ;;; 13. The famous @ bug. As mentioned above in TIPS, ULTRIX marks symlinks
|
|
|
480 ;;; with a trailing @ in a ls -alF listing. In order to account for this
|
|
|
481 ;;; ange-ftp looks to chop trailing @'s off of symlink names when it is
|
|
|
482 ;;; parsing a listing with the F switch. This will cause ange-ftp to
|
|
|
483 ;;; incorrectly get the name of a symlink on a non-ULTRIX host if its name
|
|
|
484 ;;; ends in an @. ange-ftp will correct itself if you take F out of the
|
|
|
485 ;;; dired ls switches (C-u s will allow you to edit the switches). The
|
|
|
486 ;;; dired buffer will be automatically reverted, which will allow ange-ftp
|
|
|
487 ;;; to fix its files hashtable. A cookie to anyone who can think of a
|
|
|
488 ;;; fast, sure-fire way to recognize ULTRIX over ftp.
