/*
|
|
* Recovery code.
|
|
*
|
|
* The basic scheme is there's a btree file, whose name we specify. The first
|
|
* time a file is modified, and then at RCV_PERIOD intervals after that, the
|
|
* btree file is synced to disk. Each time a keystroke is requested for a file
|
|
* the terminal routines check to see if the file needs to be synced. This, of
|
|
* course means that the data structures had better be consistent each time the
|
|
* key routines are called.
|
|
*
|
|
* We don't use timers other than to flag that the file should be synced. This
|
|
* would require that the SCR and EXF data structures be locked, the dbopen(3)
|
|
* routines lock out the timers for each update, etc. It's just not worth it.
|
|
* The only way we can lose in the current scheme is if the file is saved, then
|
|
* the user types furiously for RCV_PERIOD - 1 seconds, and types nothing more.
|
|
* Not likely.
|
|
*
|
|
* When a file is first modified, a file which can be handed off to the mailer
|
|
* is created. The file contains normal headers, with two additions, which
|
|
* occur in THIS order, as the FIRST TWO headers:
|
|
*
|
|
* Vi-recover-file: file_name
|
|
* Vi-recover-path: recover_path
|
|
*
|
|
* Since newlines delimit the headers, this means that file names cannot
|
|
* have newlines in them, but that's probably okay.
|
|
*
|
|
* Btree files are named "vi.XXXX" and recovery files are named "recover.XXXX".
