25 ;;; This package attempts to make accessing files and directories using FTP
26 ;;; from within GNU Emacs as simple and transparent as possible. A subset of
27 ;;; the common file-handling routines are extended to interact with FTP.
31 ;;; Some of the common GNU Emacs file-handling operations have been made
32 ;;; FTP-smart. If one of these routines is given a filename that matches
33 ;;; '/user@host:name' then it will spawn an FTP process connecting to machine
34 ;;; 'host' as account 'user' and perform its operation on the file 'name'.
36 ;;; For example: if find-file is given a filename of:
38 ;;; /ange@anorman:/tmp/notes
40 ;;; then ange-ftp spawns an FTP process, connect to the host 'anorman' as
41 ;;; user 'ange', get the file '/tmp/notes' and pop up a buffer containing the
42 ;;; contents of that file as if it were on the local filesystem. If ange-ftp
43 ;;; needs a password to connect then it reads one in the echo area.
45 ;;; Extended filename syntax:
47 ;;; The default extended filename syntax is '/user@host:name', where the
48 ;;; 'user@' part may be omitted. This syntax can be customised to a certain
49 ;;; extent by changing ange-ftp-name-format. There are limitations.
51 ;;; If the user part is omitted then ange-ftp generates a default user
52 ;;; instead whose value depends on the variable ange-ftp-default-user.
56 ;;; A password is required for each host/user pair. Ange-ftp reads passwords
57 ;;; as needed. You can also specify a password with ange-ftp-set-passwd, or
58 ;;; in a *valid* ~/.netrc file.
60 ;;; Passwords for user "anonymous":
62 ;;; Passwords for the user "anonymous" (or "ftp") are handled
63 ;;; specially. The variable `ange-ftp-generate-anonymous-password'
64 ;;; controls what happens: if the value of this variable is a string,
65 ;;; then this is used as the password; if non-nil (the default), then
66 ;;; the value of `user-mail-address' is used; if nil then the user
67 ;;; is prompted for a password as normal.
69 ;;; "Dumb" UNIX hosts:
71 ;;; The FTP servers on some UNIX machines have problems if the 'ls' command is
74 ;;; The routine ange-ftp-add-dumb-unix-host can be called to tell ange-ftp to
75 ;;; limit itself to the DIR command and not 'ls' for a given UNIX host. Note
76 ;;; that this change will take effect for the current GNU Emacs session only.
77 ;;; See below for a discussion of non-UNIX hosts. If a large number of
78 ;;; machines with similar hostnames have this problem then it is easier to set
79 ;;; the value of ange-ftp-dumb-unix-host-regexp in your .emacs file. ange-ftp
80 ;;; is unable to automatically recognize dumb unix hosts.
82 ;;; File name completion:
84 ;;; Full file-name completion is supported on UNIX, VMS, CMS, and MTS hosts.
85 ;;; To do filename completion, ange-ftp needs a listing from the remote host.
86 ;;; Therefore, for very slow connections, it might not save any time.
90 ;;; When ange-ftp starts up an FTP process, it leaves it running for speed
91 ;;; purposes. Some FTP servers will close the connection after a period of
92 ;;; time, but ange-ftp should be able to quietly reconnect the next time that
93 ;;; the process is needed.
95 ;;; Killing the "*ftp user@host*" buffer also kills the ftp process.
96 ;;; This should not cause ange-ftp any grief.
98 ;;; Binary file transfers:
100 ;;; By default ange-ftp transfers files in ASCII mode. If a file being
101 ;;; transferred matches the value of ange-ftp-binary-file-name-regexp then
102 ;;; binary mode is used for that transfer.
104 ;;; Account passwords:
106 ;;; Some FTP servers require an additional password which is sent by the
107 ;;; ACCOUNT command. ange-ftp partially supports this by allowing the user to
108 ;;; specify an account password by either calling ange-ftp-set-account, or by
109 ;;; specifying an account token in the .netrc file. If the account password
110 ;;; is set by either of these methods then ange-ftp will issue an ACCOUNT
111 ;;; command upon starting the FTP process.
115 ;;; ange-ftp can be preloaded, but must be put in the site-init.el file and
116 ;;; not the site-load.el file in order for the documentation strings for the
117 ;;; functions being overloaded to be available.
121 ;;; Most ange-ftp commands that talk to the FTP process output a status
122 ;;; message on what they are doing. In addition, ange-ftp can take advantage
123 ;;; of the FTP client's HASH command to display the status of transferring
124 ;;; files and listing directories. See the documentation for the variables
125 ;;; ange-ftp-{ascii,binary}-hash-mark-size, ange-ftp-send-hash and
126 ;;; ange-ftp-process-verbose for more details.
130 ;;; Sometimes it is necessary for the FTP process to be run on a different
131 ;;; machine than the machine running GNU Emacs. This can happen when the
132 ;;; local machine has restrictions on what hosts it can access.
134 ;;; ange-ftp has support for running the ftp process on a different (gateway)
135 ;;; machine. The way it works is as follows:
137 ;;; 1) Set the variable 'ange-ftp-gateway-host' to the name of a machine
138 ;;; that doesn't have the access restrictions.
140 ;;; 2) Set the variable 'ange-ftp-local-host-regexp' to a regular expression
141 ;;; that matches hosts that can be contacted from running a local ftp
142 ;;; process, but fails to match hosts that can't be accessed locally. For
145 ;;; "\\.hp\\.com$\\|^[^.]*$"
147 ;;; will match all hosts that are in the .hp.com domain, or don't have an
148 ;;; explicit domain in their name, but will fail to match hosts with
149 ;;; explicit domains or that are specified by their ip address.
151 ;;; 3) Using NFS and symlinks, make sure that there is a shared directory with
152 ;;; the *same* name between the local machine and the gateway machine.
153 ;;; This directory is necessary for temporary files created by ange-ftp.
155 ;;; 4) Set the variable 'ange-ftp-gateway-tmp-name-template' to the name of
156 ;;; this directory plus an identifying filename prefix. For example:
158 ;;; "/nfs/hplose/ange/ange-ftp"
160 ;;; where /nfs/hplose/ange is a directory that is shared between the
161 ;;; gateway machine and the local machine.
163 ;;; The simplest way of getting a ftp process running on the gateway machine
164 ;;; is if you can spawn a remote shell using either 'rsh' or 'remsh'. If you
165 ;;; can't do this for some reason such as security then points 7 onwards will
166 ;;; discuss an alternative approach.
168 ;;; 5) Set the variable ange-ftp-gateway-program to the name of the remote
169 ;;; shell process such as 'remsh' or 'rsh' if the default isn't correct.
171 ;;; 6) Set the variable ange-ftp-gateway-program-interactive to nil if it
172 ;;; isn't already. This tells ange-ftp that you are using a remote shell
173 ;;; rather than logging in using telnet or rlogin.
175 ;;; That should be all you need to allow ange-ftp to spawn a ftp process on
176 ;;; the gateway machine. If you have to use telnet or rlogin to get to the
177 ;;; gateway machine then follow the instructions below.
179 ;;; 7) Set the variable ange-ftp-gateway-program to the name of the program
180 ;;; that lets you log onto the gateway machine. This may be something like
181 ;;; telnet or rlogin.
183 ;;; 8) Set the variable ange-ftp-gateway-prompt-pattern to a regular
184 ;;; expression that matches the prompt you get when you login to the
185 ;;; gateway machine. Be very specific here; this regexp must not match
186 ;;; *anything* in your login banner except this prompt.
187 ;;; shell-prompt-pattern is far too general as it appears to match some
188 ;;; login banners from Sun machines. For example:
192 ;;; 9) Set the variable ange-ftp-gateway-program-interactive to 't' to let
193 ;;; ange-ftp know that it has to "hand-hold" the login to the gateway
196 ;;; 10) Set the variable ange-ftp-gateway-setup-term-command to a UNIX command
197 ;;; that will put the pty connected to the gateway machine into a
198 ;;; no-echoing mode, and will strip off carriage-returns from output from
199 ;;; the gateway machine. For example:
201 ;;; "stty -onlcr -echo"
203 ;;; will work on HP-UX machines, whereas:
207 ;;; appears to work for some Sun machines.
209 ;;; That's all there is to it.
213 ;;; If you have a "smart" ftp program that allows you to issue commands like
214 ;;; "USER foo@bar" which do nice proxy things, then look at the variables
215 ;;; ange-ftp-smart-gateway and ange-ftp-smart-gateway-port.
217 ;;; Otherwise, if there is an alternate ftp program that implements proxy in
218 ;;; a transparent way (i.e. w/o specifying the proxy host), that will
219 ;;; connect you directly to the desired destination host:
220 ;;; Set ange-ftp-gateway-ftp-program-name to that program's name.
221 ;;; Set ange-ftp-local-host-regexp to a value as stated earlier on.
222 ;;; Leave ange-ftp-gateway-host set to nil.
223 ;;; Set ange-ftp-smart-gateway to t.
225 ;;; Tips for using ange-ftp:
227 ;;; 1. For dired to work on a host which marks symlinks with a trailing @ in
228 ;;; an ls -alF listing, you need to (setq dired-ls-F-marks-symlinks t).
229 ;;; Most UNIX systems do not do this, but ULTRIX does. If you think that
230 ;;; there is a chance you might connect to an ULTRIX machine (such as
231 ;;; prep.ai.mit.edu), then set this variable accordingly. This will have
232 ;;; the side effect that dired will have problems with symlinks whose names
233 ;;; end in an @. If you get yourself into this situation then editing
234 ;;; dired's ls-switches to remove "F", will temporarily fix things.
236 ;;; 2. If you know that you are connecting to a certain non-UNIX machine
237 ;;; frequently, and ange-ftp seems to be unable to guess its host-type,
238 ;;; then setting the appropriate host-type regexp
239 ;;; (ange-ftp-vms-host-regexp, ange-ftp-mts-host-regexp, or
240 ;;; ange-ftp-cms-host-regexp) accordingly should help. Also, please report
241 ;;; ange-ftp's inability to recognize the host-type as a bug.
243 ;;; 3. For slow connections, you might get "listing unreadable" error
244 ;;; messages, or get an empty buffer for a file that you know has something
245 ;;; in it. The solution is to increase the value of ange-ftp-retry-time.
246 ;;; Its default value is 5 which is plenty for reasonable connections.
247 ;;; However, for some transatlantic connections I set this to 20.
249 ;;; 4. Beware of compressing files on non-UNIX hosts. Ange-ftp will do it by
250 ;;; copying the file to the local machine, compressing it there, and then
251 ;;; sending it back. Binary file transfers between machines of different
252 ;;; architectures can be a risky business. Test things out first on some
253 ;;; test files. See "Bugs" below. Also, note that ange-ftp copies files by
254 ;;; moving them through the local machine. Again, be careful when doing
255 ;;; this with binary files on non-Unix machines.
257 ;;; 5. Beware that dired over ftp will use your setting of dired-no-confirm
258 ;;; (list of dired commands for which confirmation is not asked). You
259 ;;; might want to reconsider your setting of this variable, because you
260 ;;; might want confirmation for more commands on remote direds than on
261 ;;; local direds. For example, I strongly recommend that you not include
262 ;;; compress and uncompress in this list. If there is enough demand it
263 ;;; might be a good idea to have an alist ange-ftp-dired-no-confirm of
264 ;;; pairs ( TYPE . LIST ), where TYPE is an operating system type and LIST
265 ;;; is a list of commands for which confirmation would be suppressed. Then
266 ;;; remote dired listings would take their (buffer-local) value of
267 ;;; dired-no-confirm from this alist. Who votes for this?
269 ;;; ---------------------------------------------------------------------
270 ;;; Non-UNIX support:
271 ;;; ---------------------------------------------------------------------
275 ;;; Ange-ftp has full support for VMS hosts. It
276 ;;; should be able to automatically recognize any VMS machine. However, if it
277 ;;; fails to do this, you can use the command ange-ftp-add-vms-host. As well,
278 ;;; you can set the variable ange-ftp-vms-host-regexp in your .emacs file. We
279 ;;; would be grateful if you would report any failures to automatically
280 ;;; recognize a VMS host as a bug.
284 ;;; For ease of *implementation*, the user enters the VMS filename syntax in a
285 ;;; UNIX-y way. For example:
286 ;;; PUB$:[ANONYMOUS.SDSCPUB.NEXT]README.TXT;1
287 ;;; would be entered as:
288 ;;; /PUB$$:/ANONYMOUS/SDSCPUB/NEXT/README.TXT;1
289 ;;; i.e. to log in as anonymous on ymir.claremont.edu and grab the file:
290 ;;; [.CSV.POLICY]RULES.MEM
292 ;;; C-x C-f /anonymous@ymir.claremont.edu:CSV/POLICY/RULES.MEM
294 ;;; A legal VMS filename is of the form: FILE.TYPE;##
295 ;;; where FILE can be up to 39 characters
296 ;;; TYPE can be up to 39 characters
297 ;;; ## is a version number (an integer between 1 and 32,767)
298 ;;; Valid characters in FILE and TYPE are A-Z 0-9 _ - $
299 ;;; $ cannot begin a filename, and - cannot be used as the first or last
303 ;;; 1. Although VMS is not case sensitive, EMACS running under UNIX is.
304 ;;; Therefore, to access a VMS file, you must enter the filename with upper
306 ;;; 2. To access the latest version of file under VMS, you use the filename
307 ;;; without the ";" and version number. You should always edit the latest
308 ;;; version of a file. If you want to edit an earlier version, copy it to a
309 ;;; new file first. This has nothing to do with ange-ftp, but is simply
310 ;;; good VMS operating practice. Therefore, to edit FILE.TXT;3 (say 3 is
311 ;;; latest version), do C-x C-f /ymir.claremont.edu:FILE.TXT. If you
312 ;;; inadvertently do C-x C-f /ymir.claremont.edu:FILE.TXT;3, you will find
313 ;;; that VMS will not allow you to save the file because it will refuse to
314 ;;; overwrite FILE.TXT;3, but instead will want to create FILE.TXT;4, and
315 ;;; attach the buffer to this file. To get out of this situation, M-x
316 ;;; write-file /ymir.claremont.edu:FILE.TXT will attach the buffer to
317 ;;; latest version of the file. For this reason, in dired "f"
318 ;;; (dired-find-file), always loads the file sans version, whereas "v",
319 ;;; (dired-view-file), always loads the explicit version number. The
320 ;;; reasoning being that it reasonable to view old versions of a file, but
321 ;;; not to edit them.
322 ;;; 3. EMACS has a feature in which it does environment variable substitution
323 ;;; in filenames. Therefore, to enter a $ in a filename, you must quote it
328 ;;; Ange-ftp has full support for hosts running
329 ;;; the Michigan terminal system. It should be able to automatically
330 ;;; recognize any MTS machine. However, if it fails to do this, you can use
331 ;;; the command ange-ftp-add-mts-host. As well, you can set the variable
332 ;;; ange-ftp-mts-host-regexp in your .emacs file. We would be grateful if you
333 ;;; would report any failures to automatically recognize a MTS host as a bug.
337 ;;; MTS filenames are entered in a UNIX-y way. For example, if your account
338 ;;; was YYYY, the file FILE in the account XXXX: on mtsg.ubc.ca would be
340 ;;; /YYYY@mtsg.ubc.ca:/XXXX:/FILE
341 ;;; In other words, MTS accounts are treated as UNIX directories. Of course,
342 ;;; to access a file in another account, you must have access permission for
343 ;;; it. If FILE were in your own account, then you could enter it in a
344 ;;; relative name fashion as
345 ;;; /YYYY@mtsg.ubc.ca:FILE
346 ;;; MTS filenames can be up to 12 characters. Like UNIX, the structure of the
347 ;;; filename does not contain a TYPE (i.e. it can have as many "."'s as you
348 ;;; like.) MTS filenames are always in upper case, and hence be sure to enter
349 ;;; them as such! MTS is not case sensitive, but an EMACS running under UNIX
354 ;;; Ange-ftp has full support for hosts running
355 ;;; CMS. It should be able to automatically recognize any CMS machine.
356 ;;; However, if it fails to do this, you can use the command
357 ;;; ange-ftp-add-cms-host. As well, you can set the variable
358 ;;; ange-ftp-cms-host-regexp in your .emacs file. We would be grateful if you
359 ;;; would report any failures to automatically recognize a CMS host as a bug.
363 ;;; CMS filenames are entered in a UNIX-y way. In otherwords, minidisks are
364 ;;; treated as UNIX directories. For example to access the file READ.ME in
365 ;;; minidisk *.311 on cuvmb.cc.columbia.edu, you would enter
366 ;;; /anonymous@cuvmb.cc.columbia.edu:/*.311/READ.ME
367 ;;; If *.301 is the default minidisk for this account, you could access
368 ;;; FOO.BAR on this minidisk as
369 ;;; /anonymous@cuvmb.cc.columbia.edu:FOO.BAR
370 ;;; CMS filenames are of the form FILE.TYPE, where both FILE and TYPE can be
371 ;;; up to 8 characters. Again, beware that CMS filenames are always upper
372 ;;; case, and hence must be entered as such.
375 ;;; 1. CMS machines, with the exception of anonymous accounts, nearly always
376 ;;; need an account password. To have ange-ftp send an account password,
377 ;;; you can either include it in your .netrc file, or use
378 ;;; ange-ftp-set-account.
379 ;;; 2. Ange-ftp cannot send "write passwords" for a minidisk. Hopefully, we
382 ;;; ------------------------------------------------------------------
384 ;;; ------------------------------------------------------------------
386 ;;; 1. Umask problems:
387 ;;; Be warned that files created by using ange-ftp will take account of the
388 ;;; umask of the ftp daemon process rather than the umask of the creating
389 ;;; user. This is particularly important when logging in as the root user.
390 ;;; The way that I tighten up the ftp daemon's umask under HP-UX is to make
391 ;;; sure that the umask is changed to 027 before I spawn /etc/inetd. I
392 ;;; suspect that there is something similar on other systems.
394 ;;; 2. Some combinations of FTP clients and servers break and get out of sync
395 ;;; when asked to list a non-existent directory. Some of the ai.mit.edu
396 ;;; machines cause this problem for some FTP clients. Using
397 ;;; ange-ftp-kill-ftp-process can restart the ftp process, which
398 ;;; should get things back in synch.
400 ;;; 3. Ange-ftp does not check to make sure that when creating a new file,
401 ;;; you provide a valid filename for the remote operating system.
402 ;;; If you do not, then the remote FTP server will most likely
403 ;;; translate your filename in some way. This may cause ange-ftp to
404 ;;; get confused about what exactly is the name of the file. The
405 ;;; most common causes of this are using lower case filenames on systems
406 ;;; which support only upper case, and using filenames which are too
409 ;;; 4. Null (blank) passwords confuse both ange-ftp and some FTP daemons.
411 ;;; 5. Ange-ftp likes to use pty's to talk to its FTP processes. If GNU Emacs
412 ;;; for some reason creates a FTP process that only talks via pipes then
413 ;;; ange-ftp won't be getting the information it requires at the time that
414 ;;; it wants it since pipes flush at different times to pty's. One
415 ;;; disgusting way around this problem is to talk to the FTP process via
416 ;;; rlogin which does the 'right' things with pty's.
418 ;;; 6. For CMS support, we send too many cd's. Since cd's are cheap, I haven't
419 ;;; worried about this too much. Eventually, we should have some caching
420 ;;; of the current minidisk.
422 ;;; 7. Some CMS machines do not assign a default minidisk when you ftp them as
423 ;;; anonymous. It is then necessary to guess a valid minidisk name, and cd
424 ;;; to it. This is (understandably) beyond ange-ftp.
426 ;;; 8. Remote to remote copying of files on non-Unix machines can be risky.
427 ;;; Depending on the variable ange-ftp-binary-file-name-regexp, ange-ftp
428 ;;; will use binary mode for the copy. Between systems of different
429 ;;; architecture, this still may not be enough to guarantee the integrity
430 ;;; of binary files. Binary file transfers from VMS machines are
431 ;;; particularly problematical. Should ange-ftp-binary-file-name-regexp be
432 ;;; an alist of OS type, regexp pairs?
434 ;;; 9. The code to do compression of files over ftp is not as careful as it
435 ;;; should be. It deletes the old remote version of the file, before
436 ;;; actually checking if the local to remote transfer of the compressed
437 ;;; file succeeds. Of course to delete the original version of the file
438 ;;; after transferring the compressed version back is also dangerous,
439 ;;; because some OS's have severe restrictions on the length of filenames,
440 ;;; and when the compressed version is copied back the "-Z" or ".Z" may be
441 ;;; truncated. Then, ange-ftp would delete the only remaining version of
442 ;;; the file. Maybe ange-ftp should make backups when it compresses files
443 ;;; (of course, the backup "~" could also be truncated off, sigh...).
447 ;;; 10. If a dir listing is attempted for an empty directory on (at least
448 ;;; some) VMS hosts, an ftp error is given. This is really an ftp bug, and
449 ;;; I don't know how to get ange-ftp work to around it.
451 ;;; 11. Bombs on filenames that start with a space. Deals well with filenames
452 ;;; containing spaces, but beware that the remote ftpd may not like them
455 ;;; 12. The dired support for non-Unix-like systems does not currently work.
456 ;;; It needs to be reimplemented by modifying the parse-...-listing
457 ;;; functions to convert the directory listing to ls -l format.
459 ;;; 13. The famous @ bug. As mentioned above in TIPS, ULTRIX marks symlinks
460 ;;; with a trailing @ in a ls -alF listing. In order to account for this
461 ;;; ange-ftp looks to chop trailing @'s off of symlink names when it is
462 ;;; parsing a listing with the F switch. This will cause ange-ftp to
463 ;;; incorrectly get the name of a symlink on a non-ULTRIX host if its name
464 ;;; ends in an @. ange-ftp will correct itself if you take F out of the
465 ;;; dired ls switches (C-u s will allow you to edit the switches). The
466 ;;; dired buffer will be automatically reverted, which will allow ange-ftp
467 ;;; to fix its files hashtable. A cookie to anyone who can think of a
468 ;;; fast, sure-fire way to recognize ULTRIX over ftp.

515 ;;; Technical information on this package:
516 ;;; -----------------------------------------------------------
518 ;;; ange-ftp works by putting a handler on file-name-handler-alist
519 ;;; which is called by many primitives, and a few non-primitives,
520 ;;; whenever they see a file name of the appropriate sort.
522 ;;; Checklist for adding non-UNIX support for TYPE
524 ;;; The following functions may need TYPE versions:
525 ;;; (not all functions will be needed for every OS)
527 ;;; ange-ftp-fix-name-for-TYPE
528 ;;; ange-ftp-fix-dir-name-for-TYPE
529 ;;; ange-ftp-TYPE-host
530 ;;; ange-ftp-TYPE-add-host
531 ;;; ange-ftp-parse-TYPE-listing
532 ;;; ange-ftp-TYPE-delete-file-entry
533 ;;; ange-ftp-TYPE-add-file-entry
534 ;;; ange-ftp-TYPE-file-name-as-directory
535 ;;; ange-ftp-TYPE-make-compressed-filename
536 ;;; ange-ftp-TYPE-file-name-sans-versions
540 ;;; ange-ftp-TYPE-host-regexp
541 ;;; May need to add TYPE to ange-ftp-dumb-host-types
543 ;;; Check the following functions for OS dependent coding:
545 ;;; ange-ftp-host-type
546 ;;; ange-ftp-guess-host-type
547 ;;; ange-ftp-allow-child-lookup
549 ;;; Host type conventions:
551 ;;; The function ange-ftp-host-type and the variable ange-ftp-dired-host-type
552 ;;; (mostly) follow the following conventions for remote host types. At
553 ;;; least, I think that future code should try to follow these conventions,
554 ;;; and the current code should eventually be made compliant.
556 ;;; nil = local host type, whatever that is (probably unix).
557 ;;; Think nil as in "not a remote host". This value is used by
558 ;;; ange-ftp-dired-host-type for local buffers.
560 ;;; t = a remote host of unknown type. Think t is in true, it's remote.
561 ;;; Currently, 'unix is used as the default remote host type.
562 ;;; Maybe we should use t.
564 ;;; 'type = a remote host of TYPE type.
566 ;;; 'type:list = a remote host of TYPE type, using a specialized ftp listing
567 ;;; program called list. This is currently only used for Unix
568 ;;; dl (descriptive listings), when ange-ftp-dired-host-type
569 ;;; is set to 'unix:dl.
571 ;;; Bug report codes:
573 ;;; Because of their naive faith in this code, there are certain situations
574 ;;; which the writers of this program believe could never happen. However,
575 ;;; being realists they have put calls to `error' in the program at these
576 ;;; points. These errors provide a code, which is an integer, greater than 1.
577 ;;; To aid debugging. the error codes, and the functions in which they reside
578 ;;; are listed below.
