Two callers of get_spendable_coins were removing frozen addrs
before calling. Put that functionality in the function.
We shouldn't be able to send_from a frozen address. This was
possible in the current release because logic assumed a two-element
tuple was returned when it is now three-element. Fix that too.
Command line options listunspent and createrawtransaction currently
ignore frozen addresses. I'm not sure that's right but I've preserved
that behaviour.
With this patch only the wallet class refers to self.frozen_addresses;
other clients use is_frozen() now.
Speedup mainly from writing to storage only once.
Make frozen_addresses a set in memory, as sets give cleaner
code and are more efficient.
Minor change in behaviour: command line freezing used to return
False if the address isn't in the wallet OR the address was already
frozen. Now it returns more like a success code: it returns False
only if the address isn't in the wallet regardless of frozen state.
Similarly for unfreezing.
interfaces we have created.
Existing code has the concept of pending servers, where a connection
thread is started but has not sent a connection notification, and
and interfaces which have received the notification.
This separation caused a couple of minor bugs, and given the cleaner
semantics of unifying the two I don't think the separation is beneficial.
The bugs:
1) When stopping the network, we only stopped the connected interface
threads, not the pending ones. This would leave Python hanging
on exit if we don't make them daemon threads.
2) start_interface() did not check pending servers before starting
a new thread. Some of its callers did, but not all, so it was
possible to initiate two threads to one server and "lose" one thread.
Apart form fixing the above two issues, unification causes one more
change in semantics: we are now willing to switch to a connection
that is pending (we don't switch to failed interfaces). I don't
think that is a problem: if it times out we'll just switch
again when we receive the disconnect notification, and previously the
fact that an interface was in the interaces dictionary wasn't a
guarantee the connection was good anyway: we might not have processed
a pending disconnection notification.
As discussed on #electrum yesterday.
Increase change gap limit to 6.
Choose the next unused change address, if any, otherwise pick
one at random from the gap limit.
Fees should be recalculated when send_from changes.
Fees should be recalculated when editing fee preference, but
only save to storage when leaving the fee per kb widget.
No need to emit a textEdited signal; the widget does that already
(with the effect that we used to call update_fee() twice).
Three places used to test for lagging and switch. Commonize the
code. We test for lagging before autoconnect so lagging
diagnostics are output if not auto-connect.
Lagging diagnotics moved to server_is_lagging().
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.
