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.
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).
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.
The verifier will retain responsibility for verification, but will no longer
hold the transaction sets itself.
Change requires_fee to take a wallet.
Add new function add_unverified_tx()
Move get_confirmations() to the wallet from the verifier.
The call to update_wallet() is redundant with earlier call to load_wallet().
Set the need_update boolean so the timer will refresh rather than
unconditionally refreshing. This typically results in it merging with
the first network "updated" event resulting in one less refresh.
For me in online mode this results in history being calculated and shown
only twice during startup rather than four times.
Electrum 2.x flashes a small window during startup before the main window appears.
This turns out to be the fee edit box being enabled in create_send_tab().
Setting it to visible when the grid containing it is unparented causes QT to actually
display a window with just the edit box widget for some reason. So defer the
call to set its visibility until the grid is parented.
Block explorer code is data-driven now.
Put block explorer defaulting in one place.
Fix URLs for insight.is and blockr.io.
Add tradeblock.com explorer.
Add menu item to view address on block explorer provided only one is selected.
