Due to possibly having one account sleep while another is reading a
password, and other tricky situations, support for nice updating and
cancelling of a sleep in TTY.TTYUI has been removed. However, this is
not going to be a huge problem because the new Curses Blinkenlights
interface has this support, and does it a lot better than TTY.TTYUI
ever could have.
Reworked the canvas. Before, problem was the label and buttons to the
right of the lights would make the window too wide. When the button
got added, the window would get even wider. That was because the
canvas would not shrink. My workaround is to use a separate canvas for
each light. Seems to be OK here....
Fixed up the VerboseUI for new account system. All that really needed
updating with the "Sync immediately" button, to cope with syncing
different accounts at different times. It's better now.
More locking updates. Introduced a new MultiLock to threadutil. This
lock will let a single thread acquire the same lock more than once,
keeping track of how many times this happens, and will release the
actual lock only when the lock's lock count gets back to zero. By
using MultiLock, various functions in Curses.py and Blinkenlights.py
no longer need to pass around to other functions a parameter
indicating whether or not a lock should be obtained. This was a large
cause of complexity and errors, which is now eliminated. Everything
seems to be working properly wrt locking at this point. The
Curses.Blinkenlights interface has achieved basic working
functionality.
Updated the mbnames recorder to bring it back up-to-date with the new
account-centric system. It will now gather reports from account sync
threads, and when it has all that it's supposed to, it'll write out
the file.
Added some temporary debug code to help weed out a few race conditions
with the curses Blinkenlights interface. Think I've finally got it.
I'm leaving the debugging code in for now, though, to help in case
there are future problems.
