This makes canceling the persistance thread not rethrow an exception
which kills the process, and makes the terminal driver write one
final newline before giving control back to the terminal so the
bash prompt writes to its own line.
This gets a terminal spinner to spin after a short delay like in
vere. This also fixes a bug in termRefreshLine which was screwing
up redisplay of the terminal spinner; it hadn't been translated
from C properly.
This performs all normal filesystem operations. We can take
filesystem hash snapshots on startup, write the contents of an
%ergo to disk, send changes to Urbit with an %into, and finally
delete mount points when they are %ogre.
This doesn't deal with updating an initial filesystem on first
run with -A, or with acquiring a lockfile, which should happen
elsewhere.
Can take filesystem hash snapshots on startup, and can write the
contents of an %ergo to disk.
The compute thread should take an event or a save request or a
shutdown request. We now take snapshots every 120 seconds like
vere does, and take a snapshot before clean shutdown.
(Also changes the terminal driver so that it doesn't unboundedly
block shutdown.)
After looking at vty for a bit, I decided to just do a straight port
of term.c's raw output code. This gets the "~zod:dojo" in the right
position, though the other logging output screws things up a bit.
Joe told me to look at the Jaque terminal and I just did. That uses
the Lanterna Java library to handle terminal output. Joe then suggested
that I move the entire system here to curses or another similar library.
