2f7ea155 RS |
25 | ;;; |
26 | ;;; This package attempts to make accessing files and directories using FTP | |
27 | ;;; from within GNU Emacs as simple and transparent as possible. A subset of | |
28 | ;;; the common file-handling routines are extended to interact with FTP. | |
29 | ||
2f7ea155 RS |
30 | ;;; Usage: |
31 | ;;; | |
32 | ;;; Some of the common GNU Emacs file-handling operations have been made | |
33 | ;;; FTP-smart. If one of these routines is given a filename that matches | |
d0bc419e RS |
34 | ;;; '/user@host:name' then it will spawn an FTP process connecting to machine |
35 | ;;; 'host' as account 'user' and perform its operation on the file 'name'. | |
2f7ea155 RS |
36 | ;;; |
37 | ;;; For example: if find-file is given a filename of: | |
38 | ;;; | |
39 | ;;; /ange@anorman:/tmp/notes | |
40 | ;;; | |
d0bc419e | 41 | ;;; then ange-ftp spawns an FTP process, connect to the host 'anorman' as |
2f7ea155 RS |
42 | ;;; user 'ange', get the file '/tmp/notes' and pop up a buffer containing the |
43 | ;;; contents of that file as if it were on the local filesystem. If ange-ftp | |
d0bc419e | 44 | ;;; needs a password to connect then it reads one in the echo area. |
2f7ea155 RS |
45 | |
46 | ;;; Extended filename syntax: | |
47 | ;;; | |
d0bc419e | 48 | ;;; The default extended filename syntax is '/user@host:name', where the |
2f7ea155 | 49 | ;;; 'user@' part may be omitted. This syntax can be customised to a certain |
d0bc419e | 50 | ;;; extent by changing ange-ftp-name-format. There are limitations. |
2f7ea155 | 51 | ;;; |
d0bc419e | 52 | ;;; If the user part is omitted then ange-ftp generates a default user |
2f7ea155 RS |
53 | ;;; instead whose value depends on the variable ange-ftp-default-user. |
54 | ||
55 | ;;; Passwords: | |
56 | ;;; | |
d0bc419e RS |
57 | ;;; A password is required for each host/user pair. Ange-ftp reads passwords |
58 | ;;; as needed. You can also specify a password with ange-ftp-set-passwd, or | |
59 | ;;; in a *valid* ~/.netrc file. | |
2f7ea155 RS |
60 | |
61 | ;;; Passwords for user "anonymous": | |
62 | ;;; | |
55badf85 RS |
63 | ;;; Passwords for the user "anonymous" (or "ftp") are handled |
64 | ;;; specially. The variable `ange-ftp-generate-anonymous-password' | |
65 | ;;; controls what happens: if the value of this variable is a string, | |
66 | ;;; then this is used as the password; if non-nil (the default), then | |
67 | ;;; a password is created from the name of the user and the hostname | |
68 | ;;; of the machine on which GNU Emacs is running; if nil then the user | |
69 | ;;; is prompted for a password as normal. | |
2f7ea155 RS |
70 | |
71 | ;;; "Dumb" UNIX hosts: | |
72 | ;;; | |
73 | ;;; The FTP servers on some UNIX machines have problems if the 'ls' command is | |
74 | ;;; used. | |
75 | ;;; | |
76 | ;;; The routine ange-ftp-add-dumb-unix-host can be called to tell ange-ftp to | |
77 | ;;; limit itself to the DIR command and not 'ls' for a given UNIX host. Note | |
78 | ;;; that this change will take effect for the current GNU Emacs session only. | |
79 | ;;; See below for a discussion of non-UNIX hosts. If a large number of | |
80 | ;;; machines with similar hostnames have this problem then it is easier to set | |
81 | ;;; the value of ange-ftp-dumb-unix-host-regexp in your .emacs file. ange-ftp | |
82 | ;;; is unable to automatically recognize dumb unix hosts. | |
83 | ||
84 | ;;; File name completion: | |
85 | ;;; | |
86 | ;;; Full file-name completion is supported on UNIX, VMS, CMS, and MTS hosts. | |
87 | ;;; To do filename completion, ange-ftp needs a listing from the remote host. | |
88 | ;;; Therefore, for very slow connections, it might not save any time. | |
89 | ||
90 | ;;; FTP processes: | |
91 | ;;; | |
92 | ;;; When ange-ftp starts up an FTP process, it leaves it running for speed | |
93 | ;;; purposes. Some FTP servers will close the connection after a period of | |
94 | ;;; time, but ange-ftp should be able to quietly reconnect the next time that | |
95 | ;;; the process is needed. | |
96 | ;;; | |
d0bc419e RS |
97 | ;;; Killing the "*ftp user@host*" buffer also kills the ftp process. |
98 | ;;; This should not cause ange-ftp any grief. | |
2f7ea155 RS |
99 | |
100 | ;;; Binary file transfers: | |
101 | ;;; | |
d0bc419e RS |
102 | ;;; By default ange-ftp transfers files in ASCII mode. If a file being |
103 | ;;; transferred matches the value of ange-ftp-binary-file-name-regexp then | |
104 | ;;; binary mode is used for that transfer. | |
2f7ea155 RS |
105 | |
106 | ;;; Account passwords: | |
107 | ;;; | |
108 | ;;; Some FTP servers require an additional password which is sent by the | |
109 | ;;; ACCOUNT command. ange-ftp partially supports this by allowing the user to | |
110 | ;;; specify an account password by either calling ange-ftp-set-account, or by | |
111 | ;;; specifying an account token in the .netrc file. If the account password | |
112 | ;;; is set by either of these methods then ange-ftp will issue an ACCOUNT | |
113 | ;;; command upon starting the FTP process. | |
114 | ||
115 | ;;; Preloading: | |
116 | ;;; | |
117 | ;;; ange-ftp can be preloaded, but must be put in the site-init.el file and | |
118 | ;;; not the site-load.el file in order for the documentation strings for the | |
119 | ;;; functions being overloaded to be available. | |
120 | ||
121 | ;;; Status reports: | |
122 | ;;; | |
123 | ;;; Most ange-ftp commands that talk to the FTP process output a status | |
124 | ;;; message on what they are doing. In addition, ange-ftp can take advantage | |
125 | ;;; of the FTP client's HASH command to display the status of transferring | |
126 | ;;; files and listing directories. See the documentation for the variables | |
127 | ;;; ange-ftp-{ascii,binary}-hash-mark-size, ange-ftp-send-hash and | |
128 | ;;; ange-ftp-process-verbose for more details. | |
129 | ||
130 | ;;; Gateways: | |
131 | ;;; | |
132 | ;;; Sometimes it is neccessary for the FTP process to be run on a different | |
133 | ;;; machine than the machine running GNU Emacs. This can happen when the | |
134 | ;;; local machine has restrictions on what hosts it can access. | |
135 | ;;; | |
136 | ;;; ange-ftp has support for running the ftp process on a different (gateway) | |
137 | ;;; machine. The way it works is as follows: | |
138 | ;;; | |
139 | ;;; 1) Set the variable 'ange-ftp-gateway-host' to the name of a machine | |
140 | ;;; that doesn't have the access restrictions. | |
141 | ;;; | |
142 | ;;; 2) Set the variable 'ange-ftp-local-host-regexp' to a regular expression | |
143 | ;;; that matches hosts that can be contacted from running a local ftp | |
144 | ;;; process, but fails to match hosts that can't be accessed locally. For | |
145 | ;;; example: | |
146 | ;;; | |
147 | ;;; "\\.hp\\.com$\\|^[^.]*$" | |
148 | ;;; | |
149 | ;;; will match all hosts that are in the .hp.com domain, or don't have an | |
150 | ;;; explicit domain in their name, but will fail to match hosts with | |
151 | ;;; explicit domains or that are specified by their ip address. | |
152 | ;;; | |
153 | ;;; 3) Using NFS and symlinks, make sure that there is a shared directory with | |
154 | ;;; the *same* name between the local machine and the gateway machine. | |
155 | ;;; This directory is neccessary for temporary files created by ange-ftp. | |
156 | ;;; | |
157 | ;;; 4) Set the variable 'ange-ftp-gateway-tmp-name-template' to the name of | |
158 | ;;; this directory plus an identifying filename prefix. For example: | |
159 | ;;; | |
160 | ;;; "/nfs/hplose/ange/ange-ftp" | |
161 | ;;; | |
162 | ;;; where /nfs/hplose/ange is a directory that is shared between the | |
163 | ;;; gateway machine and the local machine. | |
164 | ;;; | |
165 | ;;; The simplest way of getting a ftp process running on the gateway machine | |
166 | ;;; is if you can spawn a remote shell using either 'rsh' or 'remsh'. If you | |
167 | ;;; can't do this for some reason such as security then points 7 onwards will | |
168 | ;;; discuss an alternative approach. | |
169 | ;;; | |
170 | ;;; 5) Set the variable ange-ftp-gateway-program to the name of the remote | |
171 | ;;; shell process such as 'remsh' or 'rsh' if the default isn't correct. | |
172 | ;;; | |
173 | ;;; 6) Set the variable ange-ftp-gateway-program-interactive to nil if it | |
174 | ;;; isn't already. This tells ange-ftp that you are using a remote shell | |
175 | ;;; rather than logging in using telnet or rlogin. | |
176 | ;;; | |
177 | ;;; That should be all you need to allow ange-ftp to spawn a ftp process on | |
178 | ;;; the gateway machine. If you have to use telnet or rlogin to get to the | |
179 | ;;; gateway machine then follow the instructions below. | |
180 | ;;; | |
181 | ;;; 7) Set the variable ange-ftp-gateway-program to the name of the program | |
182 | ;;; that lets you log onto the gateway machine. This may be something like | |
183 | ;;; telnet or rlogin. | |
184 | ;;; | |
185 | ;;; 8) Set the variable ange-ftp-gateway-prompt-pattern to a regular | |
186 | ;;; expression that matches the prompt you get when you login to the | |
187 | ;;; gateway machine. Be very specific here; this regexp must not match | |
188 | ;;; *anything* in your login banner except this prompt. | |
189 | ;;; shell-prompt-pattern is far too general as it appears to match some | |
190 | ;;; login banners from Sun machines. For example: | |
191 | ;;; | |
192 | ;;; "^$*$ *" | |
193 | ;;; | |
194 | ;;; 9) Set the variable ange-ftp-gateway-program-interactive to 't' to let | |
195 | ;;; ange-ftp know that it has to "hand-hold" the login to the gateway | |
196 | ;;; machine. | |
197 | ;;; | |
198 | ;;; 10) Set the variable ange-ftp-gateway-setup-term-command to a UNIX command | |
199 | ;;; that will put the pty connected to the gateway machine into a | |
200 | ;;; no-echoing mode, and will strip off carriage-returns from output from | |
201 | ;;; the gateway machine. For example: | |
202 | ;;; | |
203 | ;;; "stty -onlcr -echo" | |
204 | ;;; | |
205 | ;;; will work on HP-UX machines, whereas: | |
206 | ;;; | |
207 | ;;; "stty -echo nl" | |
208 | ;;; | |
209 | ;;; appears to work for some Sun machines. | |
210 | ;;; | |
211 | ;;; That's all there is to it. | |
212 | ||
213 | ;;; Smart gateways: | |
214 | ;;; | |
215 | ;;; If you have a "smart" ftp program that allows you to issue commands like | |
216 | ;;; "USER foo@bar" which do nice proxy things, then look at the variables | |
217 | ;;; ange-ftp-smart-gateway and ange-ftp-smart-gateway-port. | |
218 | ||
219 | ;;; Tips for using ange-ftp: | |
220 | ;;; | |
221 | ;;; 1. For dired to work on a host which marks symlinks with a trailing @ in | |
222 | ;;; an ls -alF listing, you need to (setq dired-ls-F-marks-symlinks t). | |
223 | ;;; Most UNIX systems do not do this, but ULTRIX does. If you think that | |
224 | ;;; there is a chance you might connect to an ULTRIX machine (such as | |
225 | ;;; prep.ai.mit.edu), then set this variable accordingly. This will have | |
226 | ;;; the side effect that dired will have problems with symlinks whose names | |
227 | ;;; end in an @. If you get youself into this situation then editing | |
228 | ;;; dired's ls-switches to remove "F", will temporarily fix things. | |
229 | ;;; | |
230 | ;;; 2. If you know that you are connecting to a certain non-UNIX machine | |
231 | ;;; frequently, and ange-ftp seems to be unable to guess its host-type, | |
232 | ;;; then setting the appropriate host-type regexp | |
233 | ;;; (ange-ftp-vms-host-regexp, ange-ftp-mts-host-regexp, or | |
234 | ;;; ange-ftp-cms-host-regexp) accordingly should help. Also, please report | |
235 | ;;; ange-ftp's inability to recognize the host-type as a bug. | |
236 | ;;; | |
237 | ;;; 3. For slow connections, you might get "listing unreadable" error | |
238 | ;;; messages, or get an empty buffer for a file that you know has something | |
239 | ;;; in it. The solution is to increase the value of ange-ftp-retry-time. | |
240 | ;;; Its default value is 5 which is plenty for reasonable connections. | |
241 | ;;; However, for some transatlantic connections I set this to 20. | |
242 | ;;; | |
243 | ;;; 4. Beware of compressing files on non-UNIX hosts. Ange-ftp will do it by | |
244 | ;;; copying the file to the local machine, compressing it there, and then | |
245 | ;;; sending it back. Binary file transfers between machines of different | |
246 | ;;; architectures can be a risky business. Test things out first on some | |
247 | ;;; test files. See "Bugs" below. Also, note that ange-ftp copies files by | |
248 | ;;; moving them through the local machine. Again, be careful when doing | |
249 | ;;; this with binary files on non-Unix machines. | |
250 | ;;; | |
251 | ;;; 5. Beware that dired over ftp will use your setting of dired-no-confirm | |
252 | ;;; (list of dired commands for which confirmation is not asked). You | |
253 | ;;; might want to reconsider your setting of this variable, because you | |
254 | ;;; might want confirmation for more commands on remote direds than on | |
255 | ;;; local direds. For example, I strongly recommend that you not include | |
256 | ;;; compress and uncompress in this list. If there is enough demand it | |
257 | ;;; might be a good idea to have an alist ange-ftp-dired-no-confirm of | |
258 | ;;; pairs ( TYPE . LIST ), where TYPE is an operating system type and LIST | |
259 | ;;; is a list of commands for which confirmation would be suppressed. Then | |
260 | ;;; remote dired listings would take their (buffer-local) value of | |
261 | ;;; dired-no-confirm from this alist. Who votes for this? | |

267 | ;;; VMS support: | |
268 | ;;; | |
d0bc419e | 269 | ;;; Ange-ftp has full support for VMS hosts. It |
2f7ea155 RS |
270 | ;;; should be able to automatically recognize any VMS machine. However, if it |
271 | ;;; fails to do this, you can use the command ange-ftp-add-vms-host. As well, | |
272 | ;;; you can set the variable ange-ftp-vms-host-regexp in your .emacs file. We | |
273 | ;;; would be grateful if you would report any failures to automatically | |
274 | ;;; recognize a VMS host as a bug. | |
275 | ;;; | |
276 | ;;; Filename Syntax: | |
277 | ;;; | |
278 | ;;; For ease of *implementation*, the user enters the VMS filename syntax in a | |
279 | ;;; UNIX-y way. For example: | |
280 | ;;; PUB$:[ANONYMOUS.SDSCPUB.NEXT]README.TXT;1 | |
281 | ;;; would be entered as: | |
282 | ;;; /PUB$$:/ANONYMOUS/SDSCPUB/NEXT/README.TXT;1 | |
283 | ;;; i.e. to log in as anonymous on ymir.claremont.edu and grab the file: | |
284 | ;;; [.CSV.POLICY]RULES.MEM | |
285 | ;;; you would type: | |
286 | ;;; C-x C-f /anonymous@ymir.claremont.edu:CSV/POLICY/RULES.MEM | |
287 | ;;; | |
288 | ;;; A legal VMS filename is of the form: FILE.TYPE;## | |
289 | ;;; where FILE can be up to 39 characters | |
290 | ;;; TYPE can be up to 39 characters | |
291 | ;;; ## is a version number (an integer between 1 and 32,767) | |
292 | ;;; Valid characters in FILE and TYPE are A-Z 0-9 _ - $ | |
293 | ;;; $ cannot begin a filename, and - cannot be used as the first or last | |
294 | ;;; character. | |
295 | ;;; | |
296 | ;;; Tips: | |
297 | ;;; 1. Although VMS is not case sensitive, EMACS running under UNIX is. | |
298 | ;;; Therefore, to access a VMS file, you must enter the filename with upper | |
299 | ;;; case letters. | |
300 | ;;; 2. To access the latest version of file under VMS, you use the filename | |
301 | ;;; without the ";" and version number. You should always edit the latest | |
302 | ;;; version of a file. If you want to edit an earlier version, copy it to a | |
303 | ;;; new file first. This has nothing to do with ange-ftp, but is simply | |
304 | ;;; good VMS operating practice. Therefore, to edit FILE.TXT;3 (say 3 is | |
305 | ;;; latest version), do C-x C-f /ymir.claremont.edu:FILE.TXT. If you | |
306 | ;;; inadvertently do C-x C-f /ymir.claremont.edu:FILE.TXT;3, you will find | |
307 | ;;; that VMS will not allow you to save the file because it will refuse to | |
308 | ;;; overwrite FILE.TXT;3, but instead will want to create FILE.TXT;4, and | |
309 | ;;; attach the buffer to this file. To get out of this situation, M-x | |
310 | ;;; write-file /ymir.claremont.edu:FILE.TXT will attach the buffer to | |
d0bc419e | 311 | ;;; latest version of the file. For this reason, in dired "f" |
2f7ea155 RS |
312 | ;;; (dired-find-file), always loads the file sans version, whereas "v", |
313 | ;;; (dired-view-file), always loads the explicit version number. The | |
314 | ;;; reasoning being that it reasonable to view old versions of a file, but | |
315 | ;;; not to edit them. | |
316 | ;;; 3. EMACS has a feature in which it does environment variable substitution | |
317 | ;;; in filenames. Therefore, to enter a $ in a filename, you must quote it | |
d0bc419e | 318 | ;;; by typing $$. |
2f7ea155 RS |
319 | |
320 | ;;; MTS support: | |
321 | ;;; | |
d0bc419e | 322 | ;;; Ange-ftp has full support for hosts running |
2f7ea155 RS |
323 | ;;; the Michigan terminal system. It should be able to automatically |
324 | ;;; recognize any MTS machine. However, if it fails to do this, you can use | |
325 | ;;; the command ange-ftp-add-mts-host. As well, you can set the variable | |
326 | ;;; ange-ftp-mts-host-regexp in your .emacs file. We would be grateful if you | |
327 | ;;; would report any failures to automatically recognize a MTS host as a bug. | |
328 | ;;; | |
329 | ;;; Filename syntax: | |
330 | ;;; | |
331 | ;;; MTS filenames are entered in a UNIX-y way. For example, if your account | |
332 | ;;; was YYYY, the file FILE in the account XXXX: on mtsg.ubc.ca would be | |
333 | ;;; entered as | |
334 | ;;; /YYYY@mtsg.ubc.ca:/XXXX:/FILE | |
335 | ;;; In other words, MTS accounts are treated as UNIX directories. Of course, | |
336 | ;;; to access a file in another account, you must have access permission for | |
337 | ;;; it. If FILE were in your own account, then you could enter it in a | |
d0bc419e | 338 | ;;; relative name fashion as |
2f7ea155 RS |
339 | ;;; /YYYY@mtsg.ubc.ca:FILE |
340 | ;;; MTS filenames can be up to 12 characters. Like UNIX, the structure of the | |
341 | ;;; filename does not contain a TYPE (i.e. it can have as many "."'s as you | |
342 | ;;; like.) MTS filenames are always in upper case, and hence be sure to enter | |
343 | ;;; them as such! MTS is not case sensitive, but an EMACS running under UNIX | |
344 | ;;; is. | |
345 | ||

353 | ;;; would report any failures to automatically recognize a CMS host as a bug. | |
354 | ;;; | |
355 | ;;; Filename syntax: | |
356 | ;;; | |
357 | ;;; CMS filenames are entered in a UNIX-y way. In otherwords, minidisks are | |
358 | ;;; treated as UNIX directories. For example to access the file READ.ME in | |
359 | ;;; minidisk *.311 on cuvmb.cc.columbia.edu, you would enter | |
360 | ;;; /anonymous@cuvmb.cc.columbia.edu:/*.311/READ.ME | |
361 | ;;; If *.301 is the default minidisk for this account, you could access | |
362 | ;;; FOO.BAR on this minidisk as | |
363 | ;;; /anonymous@cuvmb.cc.columbia.edu:FOO.BAR | |
364 | ;;; CMS filenames are of the form FILE.TYPE, where both FILE and TYPE can be | |
365 | ;;; up to 8 characters. Again, beware that CMS filenames are always upper | |
366 | ;;; case, and hence must be entered as such. | |
367 | ;;; | |
368 | ;;; Tips: | |
369 | ;;; 1. CMS machines, with the exception of anonymous accounts, nearly always | |
370 | ;;; need an account password. To have ange-ftp send an account password, | |
371 | ;;; you can either include it in your .netrc file, or use | |
372 | ;;; ange-ftp-set-account. | |
373 | ;;; 2. Ange-ftp cannot send "write passwords" for a minidisk. Hopefully, we | |
374 | ;;; can fix this. | |
375 | ;;; | |
376 | ;;; ------------------------------------------------------------------ | |
377 | ;;; Bugs: | |
378 | ;;; ------------------------------------------------------------------ | |
379 | ;;; | |
380 | ;;; 1. Umask problems: | |
381 | ;;; Be warned that files created by using ange-ftp will take account of the | |
382 | ;;; umask of the ftp daemon process rather than the umask of the creating | |
383 | ;;; user. This is particulary important when logging in as the root user. | |
384 | ;;; The way that I tighten up the ftp daemon's umask under HP-UX is to make | |
385 | ;;; sure that the umask is changed to 027 before I spawn /etc/inetd. I | |
386 | ;;; suspect that there is something similar on other systems. | |
387 | ;;; | |
388 | ;;; 2. Some combinations of FTP clients and servers break and get out of sync | |
389 | ;;; when asked to list a non-existent directory. Some of the ai.mit.edu | |
390 | ;;; machines cause this problem for some FTP clients. Using | |
391 | ;;; ange-ftp-kill-process can be used to restart the ftp process, which | |
392 | ;;; should get things back in synch. | |
393 | ;;; | |
394 | ;;; 3. Ange-ftp does not check to make sure that when creating a new file, | |
395 | ;;; you provide a valid filename for the remote operating system. | |
396 | ;;; If you do not, then the remote FTP server will most likely | |
397 | ;;; translate your filename in some way. This may cause ange-ftp to | |
398 | ;;; get confused about what exactly is the name of the file. The | |
399 | ;;; most common causes of this are using lower case filenames on systems | |
400 | ;;; which support only upper case, and using filenames which are too | |
401 | ;;; long. | |
402 | ;;; | |
403 | ;;; 4. Null (blank) passwords confuse both ange-ftp and some FTP daemons. | |
404 | ;;; | |
405 | ;;; 5. Ange-ftp likes to use pty's to talk to its FTP processes. If GNU Emacs | |
406 | ;;; for some reason creates a FTP process that only talks via pipes then | |
407 | ;;; ange-ftp won't be getting the information it requires at the time that | |
408 | ;;; it wants it since pipes flush at different times to pty's. One | |
409 | ;;; disgusting way around this problem is to talk to the FTP process via | |
410 | ;;; rlogin which does the 'right' things with pty's. | |
411 | ;;; | |
412 | ;;; 6. For CMS support, we send too many cd's. Since cd's are cheap, I haven't | |
413 | ;;; worried about this too much. Eventually, we should have some caching | |
414 | ;;; of the current minidisk. | |
415 | ;;; | |
416 | ;;; 7. Some CMS machines do not assign a default minidisk when you ftp them as | |
417 | ;;; anonymous. It is then necessary to guess a valid minidisk name, and cd | |
418 | ;;; to it. This is (understandably) beyond ange-ftp. | |
419 | ;;; | |
420 | ;;; 8. Remote to remote copying of files on non-Unix machines can be risky. | |
421 | ;;; Depending on the variable ange-ftp-binary-file-name-regexp, ange-ftp | |
422 | ;;; will use binary mode for the copy. Between systems of different | |
423 | ;;; architecture, this still may not be enough to guarantee the integrity | |
424 | ;;; of binary files. Binary file transfers from VMS machines are | |
425 | ;;; particularly problematical. Should ange-ftp-binary-file-name-regexp be | |
426 | ;;; an alist of OS type, regexp pairs? | |
427 | ;;; | |
428 | ;;; 9. The code to do compression of files over ftp is not as careful as it | |
429 | ;;; should be. It deletes the old remote version of the file, before | |
430 | ;;; actually checking if the local to remote transfer of the compressed | |
431 | ;;; file succeeds. Of course to delete the original version of the file | |
432 | ;;; after transferring the compressed version back is also dangerous, | |
433 | ;;; because some OS's have severe restrictions on the length of filenames, | |
434 | ;;; and when the compressed version is copied back the "-Z" or ".Z" may be | |
435 | ;;; truncated. Then, ange-ftp would delete the only remaining version of | |
436 | ;;; the file. Maybe ange-ftp should make backups when it compresses files | |
437 | ;;; (of course, the backup "~" could also be truncated off, sigh...). | |
438 | ;;; Suggestions? | |
439 | ;;; | |
440 | ||
441 | ;;; 10. If a dir listing is attempted for an empty directory on (at least | |
442 | ;;; some) VMS hosts, an ftp error is given. This is really an ftp bug, and | |
443 | ;;; I don't know how to get ange-ftp work to around it. | |
444 | ;;; | |
445 | ;;; 11. Bombs on filenames that start with a space. Deals well with filenames | |
446 | ;;; containing spaces, but beware that the remote ftpd may not like them | |
447 | ;;; much. | |
448 | ;;; | |
d0bc419e RS |
449 | ;;; 12. The dired support for non-Unix-like systems does not currently work. |
450 | ;;; It needs to be reimplemented by modifying the parse-...-listing | |
451 | ;;; functions to convert the directory listing to ls -l format. | |
2f7ea155 RS |
452 | ;;; |
453 | ;;; 13. The famous @ bug. As mentioned above in TIPS, ULTRIX marks symlinks | |
454 | ;;; with a trailing @ in a ls -alF listing. In order to account for this | |
455 | ;;; ange-ftp looks to chop trailing @'s off of symlink names when it is | |
456 | ;;; parsing a listing with the F switch. This will cause ange-ftp to | |
457 | ;;; incorrectly get the name of a symlink on a non-ULTRIX host if its name | |
458 | ;;; ends in an @. ange-ftp will correct itself if you take F out of the | |
459 | ;;; dired ls switches (C-u s will allow you to edit the switches). The | |
460 | ;;; dired buffer will be automatically reverted, which will allow ange-ftp | |
461 | ;;; to fix its files hashtable. A cookie to anyone who can think of a | |
462 | ;;; fast, sure-fire way to recognize ULTRIX over ftp. | |
