Fixes various issues and cleans up code
- Fixes issue #4500: Amount widget +/- has floating point rounding artifacts
- Amount box can now be emptied again, without clearing to 0
Also aligns the amount to the right, as in other places.
This is the first part of a huge effort to rework the handling of dependencies.
To start, this change allows all supported platforms to build against a static
Qt. 5.2.1 and 5.3 have been successfully tested against osx64, win32, win64,
linux32, and linux64.
It also makes a small change to the windows config, to allow linking against
qt builds with or without built-in libjpeg/libpng/libpcre/libz.
The actual build processes to take advantage of these changes (for gitian and
pull-tester) are coming soon. Until then, this should be a no-op.
Start the core thread only when needed for initialization
or shutdown.
Avoids a bit of overhead, and also avoids spamming two
log messages before logging is properly initialized.
The wallet now uses the mempool fee estimator with a new
command-line option: -txconfirmtarget (default: 1) instead
of using hard-coded fees or priorities.
A new bitcoind that hasn't seen enough transactions to estimate
will fall back to the old hard-coded minimum priority or
transaction fee.
-paytxfee option overrides -txconfirmtarget.
Relaying and mining code isn't changed.
For Qt, the coin control dialog now uses priority estimates to
label transaction priority (instead of hard-coded constants);
unspent outputs were consistently labeled with a much higher
priority than is justified by the free transactions actually
being accepted into blocks.
I did not implement any GUI for setting -txconfirmtarget; I would
suggest getting rid of the "Pay transaction fee" GUI and replace
it with either "target number of confirmations" or maybe
a "faster confirmation <--> lower fee" slider or select box.
Changes:
* Add Add/Have WatchOnly methods to CKeyStore, and implementations
in CBasicKeyStore.
* Add similar methods to CWallet, and support entries for it in
CWalletDB.
* Make IsMine in script/wallet return a new enum 'isminetype',
rather than a boolean. This allows distinguishing between
spendable and unspendable coins.
* Add a field fSpendable to COutput (GetAvailableCoins' return type).
* Mark watchonly coins in listunspent as 'watchonly': true.
* Add 'watchonly' to validateaddress, suppressing script/pubkey/...
in this case.
