27 | ;; An implementation of information caching for remote files. | |
28 | ||
29 | ;; Each connection, identified by a vector [method user host | |
30 | ;; localname] or by a process, has a unique cache. We distinguish 3 | |
31 | ;; kind of caches, depending on the key: | |
32 | ;; | |
33 | ;; - localname is NIL. This are reusable properties. Examples: | |
34 | ;; "remote-shell" identifies the POSIX shell to be called on the | |
35 | ;; remote host, or "perl" is the command to be called on the remote | |
2c68ca0e | 36 | ;; host when starting a Perl script. These properties are saved in |
00d6fd04 MA |
37 | ;; the file `tramp-persistency-file-name'. |
38 | ;; | |
39 | ;; - localname is a string. This are temporary properties, which are | |
40 | ;; related to the file localname is referring to. Examples: | |
12580a07 | 41 | ;; "file-exists-p" is t or nil, depending on the file existence, or |
00d6fd04 | 42 | ;; "file-attributes" caches the result of the function |
12580a07 MA |
43 | ;; `file-attributes'. These entries have a timestamp, and they |
44 | ;; expire after `remote-file-name-inhibit-cache' seconds if this | |
45 | ;; variable is set. | |
00d6fd04 MA |
46 | ;; |
47 | ;; - The key is a process. This are temporary properties related to | |
48 | ;; an open connection. Examples: "scripts" keeps shell script | |
49 | ;; definitions already sent to the remote shell, "last-cmd-time" is | |
50 | ;; the time stamp a command has been sent to the remote process. | |
