| 24 | ;;; Commentary: |
| 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 | |
| 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 |
| 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'. |
| 36 | ;; |
| 37 | ;; For example: if find-file is given a filename of: |
| 38 | ;; |
| 39 | ;; /ange@anorman:/tmp/notes |
| 40 | ;; |
| 41 | ;; then ange-ftp spawns an FTP process, connect to the host 'anorman' as |
| 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 |
| 44 | ;; needs a password to connect then it reads one in the echo area. |
| 45 | |
| 46 | ;; Extended filename syntax: |
| 47 | ;; |
| 48 | ;; The default extended filename syntax is '/user@host:name', where the |
| 49 | ;; 'user@' part may be omitted. This syntax can be customized to a certain |
| 50 | ;; extent by changing ange-ftp-name-format. There are limitations. |
| 51 | ;; The `host' part has an optional suffix `#port' which may be used to |
| 52 | ;; specify a non-default port number for the connection. |
| 53 | ;; |
| 54 | ;; If the user part is omitted then ange-ftp generates a default user |
| 55 | ;; instead whose value depends on the variable ange-ftp-default-user. |
| 56 | |
| 57 | ;; Passwords: |
| 58 | ;; |
| 59 | ;; A password is required for each host/user pair. Ange-ftp reads passwords |
| 60 | ;; as needed. You can also specify a password with ange-ftp-set-passwd, or |
| 61 | ;; in a *valid* ~/.netrc file. |
| 62 | |
| 63 | ;; Passwords for user "anonymous": |
| 64 | ;; |
| 65 | ;; Passwords for the user "anonymous" (or "ftp") are handled |
| 66 | ;; specially. The variable `ange-ftp-generate-anonymous-password' |
| 67 | ;; controls what happens: if the value of this variable is a string, |
| 68 | ;; then this is used as the password; if non-nil (the default), then |
| 69 | ;; the value of `user-mail-address' is used; if nil then the user |
| 70 | ;; is prompted for a password as normal. |
| 71 | |
| 72 | ;; "Dumb" UNIX hosts: |
| 73 | ;; |
| 74 | ;; The FTP servers on some UNIX machines have problems if the 'ls' command is |
| 75 | ;; used. |
| 76 | ;; |
| 77 | ;; The routine ange-ftp-add-dumb-unix-host can be called to tell ange-ftp to |
| 78 | ;; limit itself to the DIR command and not 'ls' for a given UNIX host. Note |
| 79 | ;; that this change will take effect for the current GNU Emacs session only. |
| 80 | ;; See below for a discussion of non-UNIX hosts. If a large number of |
| 81 | ;; machines with similar hostnames have this problem then it is easier to set |
| 82 | ;; the value of ange-ftp-dumb-unix-host-regexp in your init file. ange-ftp |
| 83 | ;; is unable to automatically recognize dumb unix hosts. |
| 84 | |
| 85 | ;; File name completion: |
| 86 | ;; |
| 87 | ;; Full file-name completion is supported on UNIX, VMS, CMS, and MTS hosts. |
| 88 | ;; To do filename completion, ange-ftp needs a listing from the remote host. |
| 89 | ;; Therefore, for very slow connections, it might not save any time. |
| 90 | |
| 91 | ;; FTP processes: |
| 92 | ;; |
| 93 | ;; When ange-ftp starts up an FTP process, it leaves it running for speed |
| 94 | ;; purposes. Some FTP servers will close the connection after a period of |
| 95 | ;; time, but ange-ftp should be able to quietly reconnect the next time that |
| 96 | ;; the process is needed. |
| 97 | ;; |
| 98 | ;; Killing the "*ftp user@host*" buffer also kills the ftp process. |
| 99 | ;; This should not cause ange-ftp any grief. |
| 100 | |
| 101 | ;; Binary file transfers: |
| 102 | ;; |
| 103 | ;; By default ange-ftp transfers files in ASCII mode. If a file being |
| 104 | ;; transferred matches the value of ange-ftp-binary-file-name-regexp then |
| 105 | ;; binary mode is used for that transfer. |
| 106 | |
| 107 | ;; Account passwords: |
| 108 | ;; |
| 109 | ;; Some FTP servers require an additional password which is sent by the |
| 110 | ;; ACCOUNT command. ange-ftp partially supports this by allowing the user to |
| 111 | ;; specify an account password by either calling ange-ftp-set-account, or by |
| 112 | ;; specifying an account token in the .netrc file. If the account password |
| 113 | ;; is set by either of these methods then ange-ftp will issue an ACCOUNT |
| 114 | ;; command upon starting the FTP process. |
| 115 | |
| 116 | ;; Preloading: |
| 117 | ;; |
| 118 | ;; ange-ftp can be preloaded, but must be put in the site-init.el file and |
| 119 | ;; not the site-load.el file in order for the documentation strings for the |
| 120 | ;; functions being overloaded to be available. |
| 121 | |
| 122 | ;; Status reports: |
| 123 | ;; |
| 124 | ;; Most ange-ftp commands that talk to the FTP process output a status |
| 125 | ;; message on what they are doing. In addition, ange-ftp can take advantage |
| 126 | ;; of the FTP client's HASH command to display the status of transferring |
| 127 | ;; files and listing directories. See the documentation for the variables |
| 128 | ;; ange-ftp-{ascii,binary}-hash-mark-size, ange-ftp-send-hash and |
| 129 | ;; ange-ftp-process-verbose for more details. |
| 130 | |
| 131 | ;; Gateways: |
| 132 | ;; |
| 133 | ;; Sometimes it is necessary for the FTP process to be run on a different |
| 134 | ;; machine than the machine running GNU Emacs. This can happen when the |
| 135 | ;; local machine has restrictions on what hosts it can access. |
| 136 | ;; |
| 137 | ;; ange-ftp has support for running the ftp process on a different (gateway) |
| 138 | ;; machine. The way it works is as follows: |
| 139 | ;; |
| 140 | ;; 1) Set the variable 'ange-ftp-gateway-host' to the name of a machine |
| 141 | ;; that doesn't have the access restrictions. |
| 142 | ;; |
| 143 | ;; 2) Set the variable 'ange-ftp-local-host-regexp' to a regular expression |
| 144 | ;; that matches hosts that can be contacted from running a local ftp |
| 145 | ;; process, but fails to match hosts that can't be accessed locally. For |
| 146 | ;; example: |
| 147 | ;; |
| 148 | ;; "\\.hp\\.com$\\|^[^.]*$" |
| 149 | ;; |
| 150 | ;; will match all hosts that are in the .hp.com domain, or don't have an |
| 151 | ;; explicit domain in their name, but will fail to match hosts with |
| 152 | ;; explicit domains or that are specified by their ip address. |
| 153 | ;; |
| 154 | ;; 3) Using NFS and symlinks, make sure that there is a shared directory with |
| 155 | ;; the *same* name between the local machine and the gateway machine. |
| 156 | ;; This directory is necessary for temporary files created by ange-ftp. |
| 157 | ;; |
| 158 | ;; 4) Set the variable 'ange-ftp-gateway-tmp-name-template' to the name of |
| 159 | ;; this directory plus an identifying filename prefix. For example: |
| 160 | ;; |
| 161 | ;; "/nfs/hplose/ange/ange-ftp" |
| 162 | ;; |
| 163 | ;; where /nfs/hplose/ange is a directory that is shared between the |
| 164 | ;; gateway machine and the local machine. |
| 165 | ;; |
| 166 | ;; The simplest way of getting a ftp process running on the gateway machine |
| 167 | ;; is if you can spawn a remote shell using either 'rsh' or 'remsh'. If you |
| 168 | ;; can't do this for some reason such as security then points 7 onwards will |
| 169 | ;; discuss an alternative approach. |
| 170 | ;; |
| 171 | ;; 5) Set the variable ange-ftp-gateway-program to the name of the remote |
| 172 | ;; shell process such as 'remsh' or 'rsh' if the default isn't correct. |
| 173 | ;; |
| 174 | ;; 6) Set the variable ange-ftp-gateway-program-interactive to nil if it |
| 175 | ;; isn't already. This tells ange-ftp that you are using a remote shell |
| 176 | ;; rather than logging in using telnet or rlogin. |
| 177 | ;; |
| 178 | ;; That should be all you need to allow ange-ftp to spawn a ftp process on |
| 179 | ;; the gateway machine. If you have to use telnet or rlogin to get to the |
| 180 | ;; gateway machine then follow the instructions below. |
| 181 | ;; |
| 182 | ;; 7) Set the variable ange-ftp-gateway-program to the name of the program |
| 183 | ;; that lets you log onto the gateway machine. This may be something like |
| 184 | ;; telnet or rlogin. |
| 185 | ;; |
| 186 | ;; 8) Set the variable ange-ftp-gateway-prompt-pattern to a regular |
| 187 | ;; expression that matches the prompt you get when you login to the |
| 188 | ;; gateway machine. Be very specific here; this regexp must not match |
| 189 | ;; *anything* in your login banner except this prompt. |
| 190 | ;; shell-prompt-pattern is far too general as it appears to match some |
| 191 | ;; login banners from Sun machines. For example: |
| 192 | ;; |
| 193 | ;; "^$*$ *" |
| 194 | ;; |
| 195 | ;; 9) Set the variable ange-ftp-gateway-program-interactive to 't' to let |
| 196 | ;; ange-ftp know that it has to "hand-hold" the login to the gateway |
| 197 | ;; machine. |
| 198 | ;; |
| 199 | ;; 10) Set the variable ange-ftp-gateway-setup-term-command to a UNIX command |
| 200 | ;; that will put the pty connected to the gateway machine into a |
| 201 | ;; no-echoing mode, and will strip off carriage-returns from output from |
| 202 | ;; the gateway machine. For example: |
| 203 | ;; |
| 204 | ;; "stty -onlcr -echo" |
| 205 | ;; |
| 206 | ;; will work on HP-UX machines, whereas: |
| 207 | ;; |
| 208 | ;; "stty -echo nl" |
| 209 | ;; |
| 210 | ;; appears to work for some Sun machines. |
| 211 | ;; |
| 212 | ;; That's all there is to it. |
| 213 | |
| 214 | ;; Smart gateways: |
| 215 | ;; |
| 216 | ;; If you have a "smart" ftp program that allows you to issue commands like |
| 217 | ;; "USER foo@bar" which do nice proxy things, then look at the variables |
| 218 | ;; ange-ftp-smart-gateway and ange-ftp-smart-gateway-port. |
| 219 | ;; |
| 220 | ;; Otherwise, if there is an alternate ftp program that implements proxy in |
| 221 | ;; a transparent way (i.e. w/o specifying the proxy host), that will |
| 222 | ;; connect you directly to the desired destination host: |
| 223 | ;; Set ange-ftp-gateway-ftp-program-name to that program's name. |
| 224 | ;; Set ange-ftp-local-host-regexp to a value as stated earlier on. |
| 225 | ;; Leave ange-ftp-gateway-host set to nil. |
| 226 | ;; Set ange-ftp-smart-gateway to t. |
| 227 | |
| 228 | ;; Tips for using ange-ftp: |
| 229 | ;; |
| 230 | ;; 1. For dired to work on a host which marks symlinks with a trailing @ in |
| 231 | ;; an ls -alF listing, you need to (setq dired-ls-F-marks-symlinks t). |
| 232 | ;; Most UNIX systems do not do this, but ULTRIX does. If you think that |
| 233 | ;; there is a chance you might connect to an ULTRIX machine (such as |
| 234 | ;; prep.ai.mit.edu), then set this variable accordingly. This will have |
| 235 | ;; the side effect that dired will have problems with symlinks whose names |
| 236 | ;; end in an @. If you get yourself into this situation then editing |
| 237 | ;; dired's ls-switches to remove "F", will temporarily fix things. |
| 238 | ;; |
| 239 | ;; 2. If you know that you are connecting to a certain non-UNIX machine |
| 240 | ;; frequently, and ange-ftp seems to be unable to guess its host-type, |
| 241 | ;; then setting the appropriate host-type regexp |
| 242 | ;; (ange-ftp-vms-host-regexp, ange-ftp-mts-host-regexp, or |
| 243 | ;; ange-ftp-cms-host-regexp) accordingly should help. Also, please report |
| 244 | ;; ange-ftp's inability to recognize the host-type as a bug. |
| 245 | ;; |
| 246 | ;; 3. For slow connections, you might get "listing unreadable" error |
| 247 | ;; messages, or get an empty buffer for a file that you know has something |
| 248 | ;; in it. The solution is to increase the value of ange-ftp-retry-time. |
| 249 | ;; Its default value is 5 which is plenty for reasonable connections. |
| 250 | ;; However, for some transatlantic connections I set this to 20. |
| 251 | ;; |
| 252 | ;; 4. Beware of compressing files on non-UNIX hosts. Ange-ftp will do it by |
| 253 | ;; copying the file to the local machine, compressing it there, and then |
| 254 | ;; sending it back. Binary file transfers between machines of different |
| 255 | ;; architectures can be a risky business. Test things out first on some |
| 256 | ;; test files. See "Bugs" below. Also, note that ange-ftp copies files by |
| 257 | ;; moving them through the local machine. Again, be careful when doing |
| 258 | ;; this with binary files on non-Unix machines. |
| 259 | ;; |
| 260 | ;; 5. Beware that dired over ftp will use your setting of dired-no-confirm |
| 261 | ;; (list of dired commands for which confirmation is not asked). You |
| 262 | ;; might want to reconsider your setting of this variable, because you |
| 263 | ;; might want confirmation for more commands on remote direds than on |
| 264 | ;; local direds. For example, I strongly recommend that you not include |
| 265 | ;; compress and uncompress in this list. If there is enough demand it |
| 266 | ;; might be a good idea to have an alist ange-ftp-dired-no-confirm of |
| 267 | ;; pairs ( TYPE . LIST ), where TYPE is an operating system type and LIST |
| 268 | ;; is a list of commands for which confirmation would be suppressed. Then |
| 269 | ;; remote dired listings would take their (buffer-local) value of |
| 270 | ;; dired-no-confirm from this alist. Who votes for this? |

| 273 | ;; Non-UNIX support: |
| 274 | ;; --------------------------------------------------------------------- |
| 275 | |
| 276 | ;; VMS support: |
| 277 | ;; |
| 278 | ;; Ange-ftp has full support for VMS hosts. It should be able to |
| 279 | ;; automatically recognize any VMS machine. However, if it fails to do |
| 280 | ;; this, you can use the command ange-ftp-add-vms-host. Also, you can |
| 281 | ;; set the variable ange-ftp-vms-host-regexp in your init file. We |
| 282 | ;; would be grateful if you would report any failures to automatically |
| 283 | ;; recognize a VMS host as a bug. |
| 284 | ;; |
| 285 | ;; Filename Syntax: |
| 286 | ;; |
| 287 | ;; For ease of *implementation*, the user enters the VMS filename syntax in a |
| 288 | ;; UNIX-y way. For example: |
| 289 | ;; PUB$:[ANONYMOUS.SDSCPUB.NEXT]README.TXT;1 |
| 290 | ;; would be entered as: |
| 291 | ;; /PUB$$:/ANONYMOUS/SDSCPUB/NEXT/README.TXT;1 |
| 292 | ;; i.e. to log in as anonymous on ymir.claremont.edu and grab the file: |
| 293 | ;; [.CSV.POLICY]RULES.MEM |
| 294 | ;; you would type: |
| 295 | ;; C-x C-f /anonymous@ymir.claremont.edu:CSV/POLICY/RULES.MEM |
| 296 | ;; |
| 297 | ;; A valid VMS filename is of the form: FILE.TYPE;## |
| 298 | ;; where FILE can be up to 39 characters |
| 299 | ;; TYPE can be up to 39 characters |
| 300 | ;; ## is a version number (an integer between 1 and 32,767) |
| 301 | ;; Valid characters in FILE and TYPE are A-Z 0-9 _ - $ |
| 302 | ;; $ cannot begin a filename, and - cannot be used as the first or last |
| 303 | ;; character. |
| 304 | ;; |
| 305 | ;; Tips: |
| 306 | ;; 1. Although VMS is not case sensitive, EMACS running under UNIX is. |
| 307 | ;; Therefore, to access a VMS file, you must enter the filename with upper |
| 308 | ;; case letters. |
| 309 | ;; 2. To access the latest version of file under VMS, you use the filename |
| 310 | ;; without the ";" and version number. You should always edit the latest |
| 311 | ;; version of a file. If you want to edit an earlier version, copy it to a |
| 312 | ;; new file first. This has nothing to do with ange-ftp, but is simply |
| 313 | ;; good VMS operating practice. Therefore, to edit FILE.TXT;3 (say 3 is |
| 314 | ;; latest version), do C-x C-f /ymir.claremont.edu:FILE.TXT. If you |
| 315 | ;; inadvertently do C-x C-f /ymir.claremont.edu:FILE.TXT;3, you will find |
| 316 | ;; that VMS will not allow you to save the file because it will refuse to |
| 317 | ;; overwrite FILE.TXT;3, but instead will want to create FILE.TXT;4, and |
| 318 | ;; attach the buffer to this file. To get out of this situation, M-x |
| 319 | ;; write-file /ymir.claremont.edu:FILE.TXT will attach the buffer to |
| 320 | ;; latest version of the file. For this reason, in dired "f" |
| 321 | ;; (dired-find-file), always loads the file sans version, whereas "v", |
| 322 | ;; (dired-view-file), always loads the explicit version number. The |
| 323 | ;; reasoning being that it reasonable to view old versions of a file, but |
| 324 | ;; not to edit them. |
| 325 | ;; 3. EMACS has a feature in which it does environment variable substitution |
| 326 | ;; in filenames. Therefore, to enter a $ in a filename, you must quote it |
| 327 | ;; by typing $$. |
| 328 | |
| 329 | ;; MTS support: |
| 330 | ;; |
| 331 | ;; Ange-ftp has full support for hosts running |
| 332 | ;; the Michigan terminal system. It should be able to automatically |
| 333 | ;; recognize any MTS machine. However, if it fails to do this, you can use |
| 334 | ;; the command ange-ftp-add-mts-host. As well, you can set the variable |
| 335 | ;; ange-ftp-mts-host-regexp in your init file. We would be grateful if you |
| 336 | ;; would report any failures to automatically recognize a MTS host as a bug. |
| 337 | ;; |
| 338 | ;; Filename syntax: |
| 339 | ;; |
| 340 | ;; MTS filenames are entered in a UNIX-y way. For example, if your account |
| 341 | ;; was YYYY, the file FILE in the account XXXX: on mtsg.ubc.ca would be |
| 342 | ;; entered as |
| 343 | ;; /YYYY@mtsg.ubc.ca:/XXXX:/FILE |
| 344 | ;; In other words, MTS accounts are treated as UNIX directories. Of course, |
| 345 | ;; to access a file in another account, you must have access permission for |
| 346 | ;; it. If FILE were in your own account, then you could enter it in a |
| 347 | ;; relative name fashion as |
| 348 | ;; /YYYY@mtsg.ubc.ca:FILE |
| 349 | ;; MTS filenames can be up to 12 characters. Like UNIX, the structure of the |
| 350 | ;; filename does not contain a TYPE (i.e. it can have as many "."'s as you |
| 351 | ;; like.) MTS filenames are always in upper case, and hence be sure to enter |
| 352 | ;; them as such! MTS is not case sensitive, but an EMACS running under UNIX |
| 353 | ;; is. |
| 354 | |
| 355 | ;; CMS support: |
| 356 | ;; |
| 357 | ;; Ange-ftp has full support for hosts running |
| 358 | ;; CMS. It should be able to automatically recognize any CMS machine. |
| 359 | ;; However, if it fails to do this, you can use the command |
| 360 | ;; ange-ftp-add-cms-host. As well, you can set the variable |
| 361 | ;; ange-ftp-cms-host-regexp in your init file. We would be grateful if you |
| 362 | ;; would report any failures to automatically recognize a CMS host as a bug. |
| 363 | ;; |
| 364 | ;; Filename syntax: |
| 365 | ;; |
| 366 | ;; CMS filenames are entered in a UNIX-y way. In otherwords, minidisks are |
| 367 | ;; treated as UNIX directories. For example to access the file READ.ME in |
| 368 | ;; minidisk *.311 on cuvmb.cc.columbia.edu, you would enter |
| 369 | ;; /anonymous@cuvmb.cc.columbia.edu:/*.311/READ.ME |
| 370 | ;; If *.301 is the default minidisk for this account, you could access |
| 371 | ;; FOO.BAR on this minidisk as |
| 372 | ;; /anonymous@cuvmb.cc.columbia.edu:FOO.BAR |
| 373 | ;; CMS filenames are of the form FILE.TYPE, where both FILE and TYPE can be |
| 374 | ;; up to 8 characters. Again, beware that CMS filenames are always upper |
| 375 | ;; case, and hence must be entered as such. |
| 376 | ;; |
| 377 | ;; Tips: |
| 378 | ;; 1. CMS machines, with the exception of anonymous accounts, nearly always |
| 379 | ;; need an account password. To have ange-ftp send an account password, |
| 380 | ;; you can either include it in your .netrc file, or use |
| 381 | ;; ange-ftp-set-account. |
| 382 | ;; 2. Ange-ftp cannot send "write passwords" for a minidisk. Hopefully, we |
| 383 | ;; can fix this. |
| 384 | ;; |
| 385 | ;; BS2000 support: |
| 386 | ;; |
| 387 | ;; Ange-ftp has full support for BS2000 hosts. It should be able to |
| 388 | ;; automatically recognize any BS2000 machine. However, if it fails to |
| 389 | ;; do this, you can use the command ange-ftp-add-bs2000-host. As well, |
| 390 | ;; you can set the variable ange-ftp-bs2000-host-regexp in your .emacs |
| 391 | ;; file. We would be grateful if you would report any failures to auto- |
| 392 | ;; matically recognize a BS2000 host as a bug. |
| 393 | ;; |
| 394 | ;; If you want to access the POSIX subsystem on BS2000 you MUST use |
| 395 | ;; command ange-ftp-add-bs2000-posix-host for that particular |
| 396 | ;; hostname. ange-ftp can't decide if you want to access the native |
| 397 | ;; filesystem or the POSIX filesystem, so it accesses the native |
| 398 | ;; filesystem by default. And if you have an ASCII filesystem in |
| 399 | ;; your BS2000 POSIX subsystem you must use |
| 400 | ;; ange-ftp-binary-file-name-regexp to access its files. |
| 401 | ;; |
| 402 | ;; Filename Syntax: |
| 403 | ;; |
| 404 | ;; For ease of *implementation*, the user enters the BS2000 filename |
| 405 | ;; syntax in a UNIX-y way. For example: |
| 406 | ;; :PUB:$PUBLIC.ANONYMOUS.SDSCPUB.NEXT.README.TXT |
| 407 | ;; would be entered as: |
| 408 | ;; /:PUB:/$$PUBLIC/ANONYMOUS.SDSCPUB.NEXT.README.TXT |
| 409 | ;; You don't have to type pubset and account, if they have default values, |
| 410 | ;; i.e. to log in as anonymous on bs2000.anywhere.com and grab the file |
| 411 | ;; IMPORTANT.TEXT.ON.BS2000 on the default pubset X on userid PUBLIC |
| 412 | ;; (there are only 8 characters in a valid username), you could type: |
| 413 | ;; C-x C-f /public@bs2000.anywhere.com:/IMPORTANT.TEXT.ON.BS2000 |
| 414 | ;; or |
| 415 | ;; C-x C-f /anonym@bs2000.anywhere.com:/:X:/$$PUBLIC/IMPORTANT.TEXT.ON.BS2000 |
| 416 | ;; |
| 417 | ;; If X is not your default pubset, you could add it as 'subdirectory' (BS2000 |
| 418 | ;; has a flat architecture) with the command |
| 419 | ;; (setq ange-ftp-bs2000-additional-pubsets '(":X:")) |
| 420 | ;; and then you could type: |
| 421 | ;; C-x C-f /anonym@bs2000.anywhere.com:/:X:/IMPORTANT.TEXT.ON.BS2000 |
| 422 | ;; |
| 423 | ;; Valid characters in an BS2000 filename are A-Z 0-9 $ # @ . - |
| 424 | ;; If the first character in a filename is # or @, this is replaced with |
| 425 | ;; ange-ftp-bs2000-special-prefix because names starting with # or @ |
| 426 | ;; are reserved for temporary files. |
| 427 | ;; This is especially important for auto-save files. |
| 428 | ;; Valid file generations are ending with ([+|-|*]0-9...) . |
| 429 | ;; File generations are not supported yet! |
| 430 | ;; A filename must at least contain one character (A-Z) and cannot be longer |
| 431 | ;; than 41 characters. |
| 432 | ;; |
| 433 | ;; Tips: |
| 434 | ;; 1. Although BS2000 is not case sensitive, EMACS running under UNIX is. |
| 435 | ;; Therefore, to access a BS2000 file, you must enter the filename with |
| 436 | ;; upper case letters. |
| 437 | ;; 2. EMACS has a feature in which it does environment variable substitution |
| 438 | ;; in filenames. Therefore, to enter a $ in a filename, you must quote it |
| 439 | ;; by typing $$. |
| 440 | ;; 3. BS2000 machines, with the exception of anonymous accounts, nearly |
| 441 | ;; always need an account password. To have ange-ftp send an account |
| 442 | ;; password, you can either include it in your .netrc file, or use |
| 443 | ;; ange-ftp-set-account. |

| 445 | ;; ------------------------------------------------------------------ |
| 446 | ;; Bugs: |
| 447 | ;; ------------------------------------------------------------------ |
| 448 | ;; |
| 449 | ;; 1. Umask problems: |
| 450 | ;; Be warned that files created by using ange-ftp will take account of the |
| 451 | ;; umask of the ftp daemon process rather than the umask of the creating |
| 452 | ;; user. This is particularly important when logging in as the root user. |
| 453 | ;; The way that I tighten up the ftp daemon's umask under HP-UX is to make |
| 454 | ;; sure that the umask is changed to 027 before I spawn /etc/inetd. I |
| 455 | ;; suspect that there is something similar on other systems. |
| 456 | ;; |
| 457 | ;; 2. Some combinations of FTP clients and servers break and get out of sync |
| 458 | ;; when asked to list a non-existent directory. Some of the ai.mit.edu |
| 459 | ;; machines cause this problem for some FTP clients. Using |
| 460 | ;; ange-ftp-kill-ftp-process can restart the ftp process, which |
| 461 | ;; should get things back in sync. |
| 462 | ;; |
| 463 | ;; 3. Ange-ftp does not check to make sure that when creating a new file, |
| 464 | ;; you provide a valid filename for the remote operating system. |
| 465 | ;; If you do not, then the remote FTP server will most likely |
| 466 | ;; translate your filename in some way. This may cause ange-ftp to |
| 467 | ;; get confused about what exactly is the name of the file. The |
| 468 | ;; most common causes of this are using lower case filenames on systems |
| 469 | ;; which support only upper case, and using filenames which are too |
| 470 | ;; long. |
| 471 | ;; |
| 472 | ;; 4. Null (blank) passwords confuse both ange-ftp and some FTP daemons. |
| 473 | ;; |
| 474 | ;; 5. Ange-ftp likes to use pty's to talk to its FTP processes. If GNU Emacs |
| 475 | ;; for some reason creates a FTP process that only talks via pipes then |
| 476 | ;; ange-ftp won't be getting the information it requires at the time that |
| 477 | ;; it wants it since pipes flush at different times to pty's. One |
| 478 | ;; disgusting way around this problem is to talk to the FTP process via |
| 479 | ;; rlogin which does the 'right' things with pty's. |
| 480 | ;; |
| 481 | ;; 6. For CMS support, we send too many cd's. Since cd's are cheap, I haven't |
| 482 | ;; worried about this too much. Eventually, we should have some caching |
| 483 | ;; of the current minidisk. |
| 484 | ;; |
| 485 | ;; 7. Some CMS machines do not assign a default minidisk when you ftp them as |
| 486 | ;; anonymous. It is then necessary to guess a valid minidisk name, and cd |
| 487 | ;; to it. This is (understandably) beyond ange-ftp. |
| 488 | ;; |
| 489 | ;; 8. Remote to remote copying of files on non-Unix machines can be risky. |
| 490 | ;; Depending on the variable ange-ftp-binary-file-name-regexp, ange-ftp |
| 491 | ;; will use binary mode for the copy. Between systems of different |
| 492 | ;; architecture, this still may not be enough to guarantee the integrity |
| 493 | ;; of binary files. Binary file transfers from VMS machines are |
| 494 | ;; particularly problematical. Should ange-ftp-binary-file-name-regexp be |
| 495 | ;; an alist of OS type, regexp pairs? |
| 496 | ;; |
| 497 | ;; 9. The code to do compression of files over ftp is not as careful as it |
| 498 | ;; should be. It deletes the old remote version of the file, before |
| 499 | ;; actually checking if the local to remote transfer of the compressed |
| 500 | ;; file succeeds. Of course to delete the original version of the file |
| 501 | ;; after transferring the compressed version back is also dangerous, |
| 502 | ;; because some OS's have severe restrictions on the length of filenames, |
| 503 | ;; and when the compressed version is copied back the "-Z" or ".Z" may be |
| 504 | ;; truncated. Then, ange-ftp would delete the only remaining version of |
| 505 | ;; the file. Maybe ange-ftp should make backups when it compresses files |
| 506 | ;; (of course, the backup "~" could also be truncated off, sigh...). |
| 507 | ;; Suggestions? |
| 508 | ;; |
| 509 | ;; 10. If a dir listing is attempted for an empty directory on (at least |
| 510 | ;; some) VMS hosts, an ftp error is given. This is really an ftp bug, and |
| 511 | ;; I don't know how to get ange-ftp work to around it. |
| 512 | ;; |
| 513 | ;; 11. Bombs on filenames that start with a space. Deals well with filenames |
| 514 | ;; containing spaces, but beware that the remote ftpd may not like them |
| 515 | ;; much. |
| 516 | ;; |
| 517 | ;; 12. The dired support for non-Unix-like systems does not currently work. |
| 518 | ;; It needs to be reimplemented by modifying the parse-...-listing |
| 519 | ;; functions to convert the directory listing to ls -l format. |
| 520 | ;; |
| 521 | ;; 13. The famous @ bug. As mentioned above in TIPS, ULTRIX marks symlinks |
| 522 | ;; with a trailing @ in a ls -alF listing. In order to account for this |
| 523 | ;; ange-ftp looks to chop trailing @'s off of symlink names when it is |
| 524 | ;; parsing a listing with the F switch. This will cause ange-ftp to |
| 525 | ;; incorrectly get the name of a symlink on a non-ULTRIX host if its name |
| 526 | ;; ends in an @. ange-ftp will correct itself if you take F out of the |
| 527 | ;; dired ls switches (C-u s will allow you to edit the switches). The |
| 528 | ;; dired buffer will be automatically reverted, which will allow ange-ftp |
| 529 | ;; to fix its files hashtable. A cookie to anyone who can think of a |
| 530 | ;; fast, sure-fire way to recognize ULTRIX over ftp. |

| 596 | ;; |
| 597 | ;; The function ange-ftp-host-type and the variable ange-ftp-dired-host-type |
| 598 | ;; (mostly) follow the following conventions for remote host types. At |
| 599 | ;; least, I think that future code should try to follow these conventions, |
| 600 | ;; and the current code should eventually be made compliant. |
| 601 | ;; |
| 602 | ;; nil = local host type, whatever that is (probably unix). |
| 603 | ;; Think nil as in "not a remote host". This value is used by |
| 604 | ;; ange-ftp-dired-host-type for local buffers. |
| 605 | ;; |
| 606 | ;; t = a remote host of unknown type. Think t as in true, it's remote. |
| 607 | ;; Currently, `unix' is used as the default remote host type. |
| 608 | ;; Maybe we should use t. |
| 609 | ;; |
| 610 | ;; TYPE = a remote host of TYPE type. |
| 611 | ;; |
| 612 | ;; TYPE:LIST = a remote host of TYPE type, using a specialized ftp listing |
| 613 | ;; program called list. This is currently only used for Unix |
| 614 | ;; dl (descriptive listings), when ange-ftp-dired-host-type |
| 615 | ;; is set to `unix:dl'. |
| 616 | |
| 617 | ;; Bug report codes: |
| 618 | ;; |
| 619 | ;; Because of their naive faith in this code, there are certain situations |
| 620 | ;; which the writers of this program believe could never happen. However, |
| 621 | ;; being realists they have put calls to `error' in the program at these |
| 622 | ;; points. These errors provide a code, which is an integer, greater than 1. |
