27 | ;;; Commentary: | |
28 | ||
29 | ;; This package attempts to make accessing files and directories using FTP | |
30 | ;; from within GNU Emacs as simple and transparent as possible. A subset of | |
31 | ;; the common file-handling routines are extended to interact with FTP. | |
32 | ||
33 | ;; Usage: | |
34 | ;; | |
35 | ;; Some of the common GNU Emacs file-handling operations have been made | |
36 | ;; FTP-smart. If one of these routines is given a filename that matches | |
37 | ;; '/user@host:name' then it will spawn an FTP process connecting to machine | |
38 | ;; 'host' as account 'user' and perform its operation on the file 'name'. | |
39 | ;; | |
40 | ;; For example: if find-file is given a filename of: | |
41 | ;; | |
42 | ;; /ange@anorman:/tmp/notes | |
43 | ;; | |
44 | ;; then ange-ftp spawns an FTP process, connect to the host 'anorman' as | |
45 | ;; user 'ange', get the file '/tmp/notes' and pop up a buffer containing the | |
46 | ;; contents of that file as if it were on the local filesystem. If ange-ftp | |
47 | ;; needs a password to connect then it reads one in the echo area. | |
48 | ||
49 | ;; Extended filename syntax: | |
50 | ;; | |
51 | ;; The default extended filename syntax is '/user@host:name', where the | |
52 | ;; 'user@' part may be omitted. This syntax can be customised to a certain | |
53 | ;; extent by changing ange-ftp-name-format. There are limitations. | |
54 | ;; The `host' part has an optional suffix `#port' which may be used to | |
55 | ;; specify a non-default port number for the connexion. | |
56 | ;; | |
57 | ;; If the user part is omitted then ange-ftp generates a default user | |
58 | ;; instead whose value depends on the variable ange-ftp-default-user. | |
59 | ||
60 | ;; Passwords: | |
61 | ;; | |
62 | ;; A password is required for each host/user pair. Ange-ftp reads passwords | |
63 | ;; as needed. You can also specify a password with ange-ftp-set-passwd, or | |
64 | ;; in a *valid* ~/.netrc file. | |
65 | ||
66 | ;; Passwords for user "anonymous": | |
67 | ;; | |
68 | ;; Passwords for the user "anonymous" (or "ftp") are handled | |
69 | ;; specially. The variable `ange-ftp-generate-anonymous-password' | |
70 | ;; controls what happens: if the value of this variable is a string, | |
71 | ;; then this is used as the password; if non-nil (the default), then | |
72 | ;; the value of `user-mail-address' is used; if nil then the user | |
73 | ;; is prompted for a password as normal. | |
74 | ||
75 | ;; "Dumb" UNIX hosts: | |
76 | ;; | |
77 | ;; The FTP servers on some UNIX machines have problems if the 'ls' command is | |
78 | ;; used. | |
79 | ;; | |
80 | ;; The routine ange-ftp-add-dumb-unix-host can be called to tell ange-ftp to | |
81 | ;; limit itself to the DIR command and not 'ls' for a given UNIX host. Note | |
82 | ;; that this change will take effect for the current GNU Emacs session only. | |
83 | ;; See below for a discussion of non-UNIX hosts. If a large number of | |
84 | ;; machines with similar hostnames have this problem then it is easier to set | |
85 | ;; the value of ange-ftp-dumb-unix-host-regexp in your .emacs file. ange-ftp | |
86 | ;; is unable to automatically recognize dumb unix hosts. | |
87 | ||
88 | ;; File name completion: | |
89 | ;; | |
90 | ;; Full file-name completion is supported on UNIX, VMS, CMS, and MTS hosts. | |
91 | ;; To do filename completion, ange-ftp needs a listing from the remote host. | |
92 | ;; Therefore, for very slow connections, it might not save any time. | |
93 | ||
94 | ;; FTP processes: | |
95 | ;; | |
96 | ;; When ange-ftp starts up an FTP process, it leaves it running for speed | |
97 | ;; purposes. Some FTP servers will close the connection after a period of | |
98 | ;; time, but ange-ftp should be able to quietly reconnect the next time that | |
99 | ;; the process is needed. | |
100 | ;; | |
101 | ;; Killing the "*ftp user@host*" buffer also kills the ftp process. | |
102 | ;; This should not cause ange-ftp any grief. | |
103 | ||
104 | ;; Binary file transfers: | |
105 | ;; | |
106 | ;; By default ange-ftp transfers files in ASCII mode. If a file being | |
107 | ;; transferred matches the value of ange-ftp-binary-file-name-regexp then | |
108 | ;; binary mode is used for that transfer. | |
109 | ||
110 | ;; Account passwords: | |
111 | ;; | |
112 | ;; Some FTP servers require an additional password which is sent by the | |
113 | ;; ACCOUNT command. ange-ftp partially supports this by allowing the user to | |
114 | ;; specify an account password by either calling ange-ftp-set-account, or by | |
115 | ;; specifying an account token in the .netrc file. If the account password | |
116 | ;; is set by either of these methods then ange-ftp will issue an ACCOUNT | |
117 | ;; command upon starting the FTP process. | |
118 | ||
119 | ;; Preloading: | |
120 | ;; | |
121 | ;; ange-ftp can be preloaded, but must be put in the site-init.el file and | |
122 | ;; not the site-load.el file in order for the documentation strings for the | |
123 | ;; functions being overloaded to be available. | |
124 | ||
125 | ;; Status reports: | |
126 | ;; | |
127 | ;; Most ange-ftp commands that talk to the FTP process output a status | |
128 | ;; message on what they are doing. In addition, ange-ftp can take advantage | |
129 | ;; of the FTP client's HASH command to display the status of transferring | |
130 | ;; files and listing directories. See the documentation for the variables | |
131 | ;; ange-ftp-{ascii,binary}-hash-mark-size, ange-ftp-send-hash and | |
132 | ;; ange-ftp-process-verbose for more details. | |
133 | ||
134 | ;; Gateways: | |
135 | ;; | |
136 | ;; Sometimes it is necessary for the FTP process to be run on a different | |
137 | ;; machine than the machine running GNU Emacs. This can happen when the | |
138 | ;; local machine has restrictions on what hosts it can access. | |
139 | ;; | |
140 | ;; ange-ftp has support for running the ftp process on a different (gateway) | |
141 | ;; machine. The way it works is as follows: | |
142 | ;; | |
143 | ;; 1) Set the variable 'ange-ftp-gateway-host' to the name of a machine | |
144 | ;; that doesn't have the access restrictions. | |
145 | ;; | |
146 | ;; 2) Set the variable 'ange-ftp-local-host-regexp' to a regular expression | |
147 | ;; that matches hosts that can be contacted from running a local ftp | |
148 | ;; process, but fails to match hosts that can't be accessed locally. For | |
149 | ;; example: | |
150 | ;; | |
151 | ;; "\\.hp\\.com$\\|^[^.]*$" | |
152 | ;; | |
153 | ;; will match all hosts that are in the .hp.com domain, or don't have an | |
154 | ;; explicit domain in their name, but will fail to match hosts with | |
155 | ;; explicit domains or that are specified by their ip address. | |
156 | ;; | |
157 | ;; 3) Using NFS and symlinks, make sure that there is a shared directory with | |
158 | ;; the *same* name between the local machine and the gateway machine. | |
159 | ;; This directory is necessary for temporary files created by ange-ftp. | |
160 | ;; | |
161 | ;; 4) Set the variable 'ange-ftp-gateway-tmp-name-template' to the name of | |
162 | ;; this directory plus an identifying filename prefix. For example: | |
163 | ;; | |
164 | ;; "/nfs/hplose/ange/ange-ftp" | |
165 | ;; | |
166 | ;; where /nfs/hplose/ange is a directory that is shared between the | |
167 | ;; gateway machine and the local machine. | |
168 | ;; | |
169 | ;; The simplest way of getting a ftp process running on the gateway machine | |
170 | ;; is if you can spawn a remote shell using either 'rsh' or 'remsh'. If you | |
171 | ;; can't do this for some reason such as security then points 7 onwards will | |
172 | ;; discuss an alternative approach. | |
173 | ;; | |
174 | ;; 5) Set the variable ange-ftp-gateway-program to the name of the remote | |
175 | ;; shell process such as 'remsh' or 'rsh' if the default isn't correct. | |
176 | ;; | |
177 | ;; 6) Set the variable ange-ftp-gateway-program-interactive to nil if it | |
178 | ;; isn't already. This tells ange-ftp that you are using a remote shell | |
179 | ;; rather than logging in using telnet or rlogin. | |
180 | ;; | |
181 | ;; That should be all you need to allow ange-ftp to spawn a ftp process on | |
182 | ;; the gateway machine. If you have to use telnet or rlogin to get to the | |
183 | ;; gateway machine then follow the instructions below. | |
184 | ;; | |
185 | ;; 7) Set the variable ange-ftp-gateway-program to the name of the program | |
186 | ;; that lets you log onto the gateway machine. This may be something like | |
187 | ;; telnet or rlogin. | |
188 | ;; | |
189 | ;; 8) Set the variable ange-ftp-gateway-prompt-pattern to a regular | |
190 | ;; expression that matches the prompt you get when you login to the | |
191 | ;; gateway machine. Be very specific here; this regexp must not match | |
192 | ;; *anything* in your login banner except this prompt. | |
193 | ;; shell-prompt-pattern is far too general as it appears to match some | |
194 | ;; login banners from Sun machines. For example: | |
195 | ;; | |
196 | ;; "^$*$ *" | |
197 | ;; | |
198 | ;; 9) Set the variable ange-ftp-gateway-program-interactive to 't' to let | |
199 | ;; ange-ftp know that it has to "hand-hold" the login to the gateway | |
200 | ;; machine. | |
201 | ;; | |
202 | ;; 10) Set the variable ange-ftp-gateway-setup-term-command to a UNIX command | |
203 | ;; that will put the pty connected to the gateway machine into a | |
204 | ;; no-echoing mode, and will strip off carriage-returns from output from | |
205 | ;; the gateway machine. For example: | |
206 | ;; | |
207 | ;; "stty -onlcr -echo" | |
208 | ;; | |
209 | ;; will work on HP-UX machines, whereas: | |
210 | ;; | |
211 | ;; "stty -echo nl" | |
212 | ;; | |
213 | ;; appears to work for some Sun machines. | |
214 | ;; | |
215 | ;; That's all there is to it. | |
216 | ||
217 | ;; Smart gateways: | |
218 | ;; | |
219 | ;; If you have a "smart" ftp program that allows you to issue commands like | |
220 | ;; "USER foo@bar" which do nice proxy things, then look at the variables | |
221 | ;; ange-ftp-smart-gateway and ange-ftp-smart-gateway-port. | |
222 | ;; | |
223 | ;; Otherwise, if there is an alternate ftp program that implements proxy in | |
224 | ;; a transparent way (i.e. w/o specifying the proxy host), that will | |
225 | ;; connect you directly to the desired destination host: | |
226 | ;; Set ange-ftp-gateway-ftp-program-name to that program's name. | |
227 | ;; Set ange-ftp-local-host-regexp to a value as stated earlier on. | |
228 | ;; Leave ange-ftp-gateway-host set to nil. | |
229 | ;; Set ange-ftp-smart-gateway to t. | |
230 | ||
231 | ;; Tips for using ange-ftp: | |
232 | ;; | |
233 | ;; 1. For dired to work on a host which marks symlinks with a trailing @ in | |
234 | ;; an ls -alF listing, you need to (setq dired-ls-F-marks-symlinks t). | |
235 | ;; Most UNIX systems do not do this, but ULTRIX does. If you think that | |
236 | ;; there is a chance you might connect to an ULTRIX machine (such as | |
237 | ;; prep.ai.mit.edu), then set this variable accordingly. This will have | |
238 | ;; the side effect that dired will have problems with symlinks whose names | |
239 | ;; end in an @. If you get yourself into this situation then editing | |
240 | ;; dired's ls-switches to remove "F", will temporarily fix things. | |
241 | ;; | |
242 | ;; 2. If you know that you are connecting to a certain non-UNIX machine | |
243 | ;; frequently, and ange-ftp seems to be unable to guess its host-type, | |
244 | ;; then setting the appropriate host-type regexp | |
245 | ;; (ange-ftp-vms-host-regexp, ange-ftp-mts-host-regexp, or | |
246 | ;; ange-ftp-cms-host-regexp) accordingly should help. Also, please report | |
247 | ;; ange-ftp's inability to recognize the host-type as a bug. | |
248 | ;; | |
249 | ;; 3. For slow connections, you might get "listing unreadable" error | |
250 | ;; messages, or get an empty buffer for a file that you know has something | |
251 | ;; in it. The solution is to increase the value of ange-ftp-retry-time. | |
252 | ;; Its default value is 5 which is plenty for reasonable connections. | |
253 | ;; However, for some transatlantic connections I set this to 20. | |
254 | ;; | |
255 | ;; 4. Beware of compressing files on non-UNIX hosts. Ange-ftp will do it by | |
256 | ;; copying the file to the local machine, compressing it there, and then | |
257 | ;; sending it back. Binary file transfers between machines of different | |
258 | ;; architectures can be a risky business. Test things out first on some | |
259 | ;; test files. See "Bugs" below. Also, note that ange-ftp copies files by | |
260 | ;; moving them through the local machine. Again, be careful when doing | |
261 | ;; this with binary files on non-Unix machines. | |
262 | ;; | |
263 | ;; 5. Beware that dired over ftp will use your setting of dired-no-confirm | |
264 | ;; (list of dired commands for which confirmation is not asked). You | |
265 | ;; might want to reconsider your setting of this variable, because you | |
266 | ;; might want confirmation for more commands on remote direds than on | |
267 | ;; local direds. For example, I strongly recommend that you not include | |
268 | ;; compress and uncompress in this list. If there is enough demand it | |
269 | ;; might be a good idea to have an alist ange-ftp-dired-no-confirm of | |
270 | ;; pairs ( TYPE . LIST ), where TYPE is an operating system type and LIST | |
271 | ;; is a list of commands for which confirmation would be suppressed. Then | |
272 | ;; remote dired listings would take their (buffer-local) value of | |
273 | ;; dired-no-confirm from this alist. Who votes for this? | |

278 | ||
279 | ;; VMS support: | |
280 | ;; | |
281 | ;; Ange-ftp has full support for VMS hosts. It | |
282 | ;; should be able to automatically recognize any VMS machine. However, if it | |
283 | ;; fails to do this, you can use the command ange-ftp-add-vms-host. As well, | |
284 | ;; you can set the variable ange-ftp-vms-host-regexp in your .emacs file. We | |
285 | ;; would be grateful if you would report any failures to automatically | |
286 | ;; recognize a VMS host as a bug. | |
287 | ;; | |
288 | ;; Filename Syntax: | |
289 | ;; | |
290 | ;; For ease of *implementation*, the user enters the VMS filename syntax in a | |
291 | ;; UNIX-y way. For example: | |
292 | ;; PUB$:[ANONYMOUS.SDSCPUB.NEXT]README.TXT;1 | |
293 | ;; would be entered as: | |
294 | ;; /PUB$$:/ANONYMOUS/SDSCPUB/NEXT/README.TXT;1 | |
295 | ;; i.e. to log in as anonymous on ymir.claremont.edu and grab the file: | |
296 | ;; [.CSV.POLICY]RULES.MEM | |
297 | ;; you would type: | |
298 | ;; C-x C-f /anonymous@ymir.claremont.edu:CSV/POLICY/RULES.MEM | |
299 | ;; | |
300 | ;; A legal VMS filename is of the form: FILE.TYPE;## | |
301 | ;; where FILE can be up to 39 characters | |
302 | ;; TYPE can be up to 39 characters | |
303 | ;; ## is a version number (an integer between 1 and 32,767) | |
304 | ;; Valid characters in FILE and TYPE are A-Z 0-9 _ - $ | |
305 | ;; $ cannot begin a filename, and - cannot be used as the first or last | |
306 | ;; character. | |
307 | ;; | |
308 | ;; Tips: | |
309 | ;; 1. Although VMS is not case sensitive, EMACS running under UNIX is. | |
310 | ;; Therefore, to access a VMS file, you must enter the filename with upper | |
311 | ;; case letters. | |
312 | ;; 2. To access the latest version of file under VMS, you use the filename | |
313 | ;; without the ";" and version number. You should always edit the latest | |
314 | ;; version of a file. If you want to edit an earlier version, copy it to a | |
315 | ;; new file first. This has nothing to do with ange-ftp, but is simply | |
316 | ;; good VMS operating practice. Therefore, to edit FILE.TXT;3 (say 3 is | |
317 | ;; latest version), do C-x C-f /ymir.claremont.edu:FILE.TXT. If you | |
318 | ;; inadvertently do C-x C-f /ymir.claremont.edu:FILE.TXT;3, you will find | |
319 | ;; that VMS will not allow you to save the file because it will refuse to | |
320 | ;; overwrite FILE.TXT;3, but instead will want to create FILE.TXT;4, and | |
321 | ;; attach the buffer to this file. To get out of this situation, M-x | |
322 | ;; write-file /ymir.claremont.edu:FILE.TXT will attach the buffer to | |
323 | ;; latest version of the file. For this reason, in dired "f" | |
324 | ;; (dired-find-file), always loads the file sans version, whereas "v", | |
325 | ;; (dired-view-file), always loads the explicit version number. The | |
326 | ;; reasoning being that it reasonable to view old versions of a file, but | |
327 | ;; not to edit them. | |
328 | ;; 3. EMACS has a feature in which it does environment variable substitution | |
329 | ;; in filenames. Therefore, to enter a $ in a filename, you must quote it | |
330 | ;; by typing $$. | |
331 | ||
332 | ;; MTS support: | |
333 | ;; | |
334 | ;; Ange-ftp has full support for hosts running | |
335 | ;; the Michigan terminal system. It should be able to automatically | |
336 | ;; recognize any MTS machine. However, if it fails to do this, you can use | |
337 | ;; the command ange-ftp-add-mts-host. As well, you can set the variable | |
338 | ;; ange-ftp-mts-host-regexp in your .emacs file. We would be grateful if you | |
339 | ;; would report any failures to automatically recognize a MTS host as a bug. | |
340 | ;; | |
341 | ;; Filename syntax: | |
25759a92 | 342 | ;; |
8749abea GM |
343 | ;; MTS filenames are entered in a UNIX-y way. For example, if your account |
344 | ;; was YYYY, the file FILE in the account XXXX: on mtsg.ubc.ca would be | |
345 | ;; entered as | |
346 | ;; /YYYY@mtsg.ubc.ca:/XXXX:/FILE | |
347 | ;; In other words, MTS accounts are treated as UNIX directories. Of course, | |
348 | ;; to access a file in another account, you must have access permission for | |
349 | ;; it. If FILE were in your own account, then you could enter it in a | |
350 | ;; relative name fashion as | |
351 | ;; /YYYY@mtsg.ubc.ca:FILE | |
352 | ;; MTS filenames can be up to 12 characters. Like UNIX, the structure of the | |
353 | ;; filename does not contain a TYPE (i.e. it can have as many "."'s as you | |
354 | ;; like.) MTS filenames are always in upper case, and hence be sure to enter | |
355 | ;; them as such! MTS is not case sensitive, but an EMACS running under UNIX | |
356 | ;; is. | |
357 | ||
358 | ;; CMS support: | |

360 | ;; Ange-ftp has full support for hosts running |
361 | ;; CMS. It should be able to automatically recognize any CMS machine. | |

364 | ;; ange-ftp-cms-host-regexp in your .emacs file. We would be grateful if you | |
365 | ;; would report any failures to automatically recognize a CMS host as a bug. | |
25759a92 | 366 | ;; |
8749abea GM |
367 | ;; Filename syntax: |
368 | ;; | |
369 | ;; CMS filenames are entered in a UNIX-y way. In otherwords, minidisks are | |
370 | ;; treated as UNIX directories. For example to access the file READ.ME in | |
371 | ;; minidisk *.311 on cuvmb.cc.columbia.edu, you would enter | |
372 | ;; /anonymous@cuvmb.cc.columbia.edu:/*.311/READ.ME | |
373 | ;; If *.301 is the default minidisk for this account, you could access | |
374 | ;; FOO.BAR on this minidisk as | |
375 | ;; /anonymous@cuvmb.cc.columbia.edu:FOO.BAR | |
376 | ;; CMS filenames are of the form FILE.TYPE, where both FILE and TYPE can be | |
377 | ;; up to 8 characters. Again, beware that CMS filenames are always upper | |
378 | ;; case, and hence must be entered as such. | |
379 | ;; | |
380 | ;; Tips: | |
381 | ;; 1. CMS machines, with the exception of anonymous accounts, nearly always | |
382 | ;; need an account password. To have ange-ftp send an account password, | |
383 | ;; you can either include it in your .netrc file, or use | |
384 | ;; ange-ftp-set-account. | |
385 | ;; 2. Ange-ftp cannot send "write passwords" for a minidisk. Hopefully, we | |
386 | ;; can fix this. | |

388 | ;; BS2000 support: |
389 | ;; | |
390 | ;; Ange-ftp has full support for BS2000 hosts. It should be able to | |
391 | ;; automatically recognize any BS2000 machine. However, if it fails to | |
392 | ;; do this, you can use the command ange-ftp-add-bs2000-host. As well, | |
393 | ;; you can set the variable ange-ftp-bs2000-host-regexp in your .emacs | |
394 | ;; file. We would be grateful if you would report any failures to auto- | |
395 | ;; matically recognize a BS2000 host as a bug. | |
396 | ;; | |
397 | ;; If you want to access the POSIX subsystem on BS2000 you MUST use | |
398 | ;; command ange-ftp-add-bs2000-posix-host for that particular | |
399 | ;; hostname. ange-ftp can't decide if you want to access the native | |
400 | ;; filesystem or the POSIX filesystem, so it accesses the native | |
401 | ;; filesystem by default. And if you have an ASCII filesystem in | |
402 | ;; your BS2000 POSIX subsystem you must use | |
403 | ;; ange-ftp-binary-file-name-regexp to access its files. | |
404 | ;; | |
405 | ;; Filename Syntax: | |
406 | ;; | |
407 | ;; For ease of *implementation*, the user enters the BS2000 filename | |
408 | ;; syntax in a UNIX-y way. For example: | |
409 | ;; :PUB:$PUBLIC.ANONYMOUS.SDSCPUB.NEXT.README.TXT | |
410 | ;; would be entered as: | |
411 | ;; /:PUB:/$$PUBLIC/ANONYMOUS.SDSCPUB.NEXT.README.TXT | |
412 | ;; You dont't have to type pubset and account, if they have default values, | |
413 | ;; i.e. to log in as anonymous on bs2000.anywhere.com and grab the file | |
414 | ;; IMPORTANT.TEXT.ON.BS2000 on the default pubset X on userid PUBLIC | |
415 | ;; (there are only 8 characters in a valid username), you could type: | |
416 | ;; C-x C-f /public@bs2000.anywhere.com:/IMPORTANT.TEXT.ON.BS2000 | |
417 | ;; or | |
418 | ;; C-x C-f /anonym@bs2000.anywhere.com:/:X:/$$PUBLIC/IMPORTANT.TEXT.ON.BS2000 | |
419 | ;; | |
420 | ;; If X is not your default pubset, you could add it as 'subdirectory' (BS2000 | |
421 | ;; has a flat architecture) with the command | |
422 | ;; (setq ange-ftp-bs2000-additional-pubsets '(":X:")) | |
423 | ;; and then you could type: | |
424 | ;; C-x C-f /anonym@bs2000.anywhere.com:/:X:/IMPORTANT.TEXT.ON.BS2000 | |
425 | ;; | |
426 | ;; Valid characters in an BS2000 filename are A-Z 0-9 $ # @ . - | |
427 | ;; If the first character in a filename is # or @, this is replaced with | |
428 | ;; ange-ftp-bs2000-special-prefix because names starting with # or @ | |
429 | ;; are reserved for temporary files. | |
430 | ;; This is especially important for auto-save files. | |
a1506d29 | 431 | ;; Valid file generations are ending with ([+|-|*]0-9...) . |
9c35d706 RS |
432 | ;; File generations are not supported yet! |
433 | ;; A filename must at least contain one character (A-Z) and cannot be longer | |
434 | ;; than 41 characters. | |
435 | ;; | |
436 | ;; Tips: | |
437 | ;; 1. Although BS2000 is not case sensitive, EMACS running under UNIX is. | |
438 | ;; Therefore, to access a BS2000 file, you must enter the filename with | |
439 | ;; upper case letters. | |
440 | ;; 2. EMACS has a feature in which it does environment variable substitution | |
441 | ;; in filenames. Therefore, to enter a $ in a filename, you must quote it | |
442 | ;; by typing $$. | |
443 | ;; 3. BS2000 machines, with the exception of anonymous accounts, nearly | |
444 | ;; always need an account password. To have ange-ftp send an account | |
445 | ;; password, you can either include it in your .netrc file, or use | |
446 | ;; ange-ftp-set-account. | |

449 | ;; Bugs: | |
450 | ;; ------------------------------------------------------------------ | |
25759a92 | 451 | ;; |
8749abea GM |
452 | ;; 1. Umask problems: |
453 | ;; Be warned that files created by using ange-ftp will take account of the | |
454 | ;; umask of the ftp daemon process rather than the umask of the creating | |
455 | ;; user. This is particularly important when logging in as the root user. | |
456 | ;; The way that I tighten up the ftp daemon's umask under HP-UX is to make | |
457 | ;; sure that the umask is changed to 027 before I spawn /etc/inetd. I | |
458 | ;; suspect that there is something similar on other systems. | |
459 | ;; | |
460 | ;; 2. Some combinations of FTP clients and servers break and get out of sync | |
461 | ;; when asked to list a non-existent directory. Some of the ai.mit.edu | |
462 | ;; machines cause this problem for some FTP clients. Using | |
463 | ;; ange-ftp-kill-ftp-process can restart the ftp process, which | |
464 | ;; should get things back in sync. | |
465 | ;; | |
466 | ;; 3. Ange-ftp does not check to make sure that when creating a new file, | |
467 | ;; you provide a valid filename for the remote operating system. | |
468 | ;; If you do not, then the remote FTP server will most likely | |
469 | ;; translate your filename in some way. This may cause ange-ftp to | |
470 | ;; get confused about what exactly is the name of the file. The | |
471 | ;; most common causes of this are using lower case filenames on systems | |
472 | ;; which support only upper case, and using filenames which are too | |
473 | ;; long. | |
474 | ;; | |
475 | ;; 4. Null (blank) passwords confuse both ange-ftp and some FTP daemons. | |
476 | ;; | |
477 | ;; 5. Ange-ftp likes to use pty's to talk to its FTP processes. If GNU Emacs | |
478 | ;; for some reason creates a FTP process that only talks via pipes then | |
479 | ;; ange-ftp won't be getting the information it requires at the time that | |
480 | ;; it wants it since pipes flush at different times to pty's. One | |
481 | ;; disgusting way around this problem is to talk to the FTP process via | |
482 | ;; rlogin which does the 'right' things with pty's. | |
483 | ;; | |
484 | ;; 6. For CMS support, we send too many cd's. Since cd's are cheap, I haven't | |
485 | ;; worried about this too much. Eventually, we should have some caching | |
486 | ;; of the current minidisk. | |
25759a92 | 487 | ;; |
8749abea GM |
488 | ;; 7. Some CMS machines do not assign a default minidisk when you ftp them as |
489 | ;; anonymous. It is then necessary to guess a valid minidisk name, and cd | |
490 | ;; to it. This is (understandably) beyond ange-ftp. | |
491 | ;; | |
492 | ;; 8. Remote to remote copying of files on non-Unix machines can be risky. | |
493 | ;; Depending on the variable ange-ftp-binary-file-name-regexp, ange-ftp | |
494 | ;; will use binary mode for the copy. Between systems of different | |
495 | ;; architecture, this still may not be enough to guarantee the integrity | |
496 | ;; of binary files. Binary file transfers from VMS machines are | |
497 | ;; particularly problematical. Should ange-ftp-binary-file-name-regexp be | |
498 | ;; an alist of OS type, regexp pairs? | |
499 | ;; | |
500 | ;; 9. The code to do compression of files over ftp is not as careful as it | |
501 | ;; should be. It deletes the old remote version of the file, before | |
502 | ;; actually checking if the local to remote transfer of the compressed | |
503 | ;; file succeeds. Of course to delete the original version of the file | |
504 | ;; after transferring the compressed version back is also dangerous, | |
505 | ;; because some OS's have severe restrictions on the length of filenames, | |
506 | ;; and when the compressed version is copied back the "-Z" or ".Z" may be | |
507 | ;; truncated. Then, ange-ftp would delete the only remaining version of | |
508 | ;; the file. Maybe ange-ftp should make backups when it compresses files | |
509 | ;; (of course, the backup "~" could also be truncated off, sigh...). | |
510 | ;; Suggestions? | |
511 | ;; | |
512 | ;; 10. If a dir listing is attempted for an empty directory on (at least | |
513 | ;; some) VMS hosts, an ftp error is given. This is really an ftp bug, and | |
514 | ;; I don't know how to get ange-ftp work to around it. | |
515 | ;; | |
516 | ;; 11. Bombs on filenames that start with a space. Deals well with filenames | |
517 | ;; containing spaces, but beware that the remote ftpd may not like them | |
518 | ;; much. | |
519 | ;; | |
520 | ;; 12. The dired support for non-Unix-like systems does not currently work. | |
521 | ;; It needs to be reimplemented by modifying the parse-...-listing | |
522 | ;; functions to convert the directory listing to ls -l format. | |
25759a92 | 523 | ;; |
8749abea GM |
524 | ;; 13. The famous @ bug. As mentioned above in TIPS, ULTRIX marks symlinks |
525 | ;; with a trailing @ in a ls -alF listing. In order to account for this | |
526 | ;; ange-ftp looks to chop trailing @'s off of symlink names when it is | |
527 | ;; parsing a listing with the F switch. This will cause ange-ftp to | |
528 | ;; incorrectly get the name of a symlink on a non-ULTRIX host if its name | |
529 | ;; ends in an @. ange-ftp will correct itself if you take F out of the | |
530 | ;; dired ls switches (C-u s will allow you to edit the switches). The | |
531 | ;; dired buffer will be automatically reverted, which will allow ange-ftp | |
532 | ;; to fix its files hashtable. A cookie to anyone who can think of a | |
533 | ;; fast, sure-fire way to recognize ULTRIX over ftp. | |

600 | ;; The function ange-ftp-host-type and the variable ange-ftp-dired-host-type | |
601 | ;; (mostly) follow the following conventions for remote host types. At | |
602 | ;; least, I think that future code should try to follow these conventions, | |
603 | ;; and the current code should eventually be made compliant. | |
604 | ;; | |
605 | ;; nil = local host type, whatever that is (probably unix). | |
606 | ;; Think nil as in "not a remote host". This value is used by | |
607 | ;; ange-ftp-dired-host-type for local buffers. | |
608 | ;; | |
609 | ;; t = a remote host of unknown type. Think t as in true, it's remote. | |
610 | ;; Currently, `unix' is used as the default remote host type. | |
611 | ;; Maybe we should use t. | |
612 | ;; | |
613 | ;; TYPE = a remote host of TYPE type. | |
614 | ;; | |
615 | ;; TYPE:LIST = a remote host of TYPE type, using a specialized ftp listing | |
616 | ;; program called list. This is currently only used for Unix | |
617 | ;; dl (descriptive listings), when ange-ftp-dired-host-type | |
618 | ;; is set to `unix:dl'. | |

622 | ;; Because of their naive faith in this code, there are certain situations | |
