Probably speeds it up by about a factor of two.
Unfortunately it needs to be another 5x faster
for sluggishness to disappear in the GUI when
typing a description in the receive tab.
Note the old code was off-by-one.
SimpleConfig claims to handle configuration options in priority
command line, user config, system config, which makes sense.
In fact it appears it used priority command line, system config,
user config.
Also, from the priority ordering, it would seem correct that a
value should be unmodifiable if and only if it's set on the command
line. Previously anything in the system config would be unmodifiable.
This patch fixes these and cleans the code up a bit. I noticed this
whilst attempting to unify the 'auto_cycle' setting.
Fixup tests accordingly.
1) For new proxy or protocol, restart the network and default to
the requested server.
2) Otherwise if we aren't using the requested server, switch to it
3) Otherwise choose a random server if the requested server is
stale and auto_connect is True
As switch_to_interface() now has another user, move the logic
there whereby we close the old interface in order to terminate
subscriptions, in order to have it in one place.
Whilst it's not a good idea to have two electrum instances
open on the same wallet, we should avoid throwing an
exception. Also note how the old code's handling of the
exception (caused by both renaming the file almost at the
same time, rather than a non-POSIX system not supporting
the atomic rename) can lead to the wallet file being lost
enirely because os.remove(self.path) succeeds and the
rename of the temporary no-longer-existing file then fails.
switch_to_random_interface used to do is_connected()
checks and remove interfaces when switching. This
is redundant: interfaces are only added to self.interfaces
once in is_connected() state from process_if_notification().
When they are disconnected, a notification is also received
and process_if_notification() performs the removal. Furthermore,
two other callers of switch_to_interface do not do explicit
is_connected() checks before calling it.
