This commit adds the ability for callers to remove pending connections
via a call to the Remove() method. With this change, upstream users of
this package can use the connmgr for more elaborate connectivity needs
as they can now cancel pending connections that are no longer needed.
new txs that it observes. The block manager alerts the fee estimator
of new and orphaned blocks.
Check for invalid state and recreate FeeEstimator if necessary.
Rollback takes a block hash rather than a BlockStamp.
Increase rounds in TestEstimateFeeRollback to test dropping txs that have been in the mempool too long.
Since the tx hash has moved to the basic filter, generating an extended filter
can result in `ErrNoData`. This is handled by writing a nil filter and giving
it a zero hash.
The cfilter BIP specifies that the filter type is a uint8. The
current code encodes it correctly on the wire, but everywhere else,
it's treated as a boolean (false for basic filter, true for
extended). This commit corrects that to account for possible
additional filter types in the future. All package changes are
done in one commit as they're all interdependent. The following
packages are updated:
* blockchain/indexers
* btcjson
* peer
* wire
* main (server.go and rpcserver.go)
The btclog package has been changed to defining its own logging
interface (rather than seelog's) and provides a default implementation
for callers to use.
There are two primary advantages to the new logger implementation.
First, all log messages are created before the call returns. Compared
to seelog, this prevents data races when mutable variables are logged.
Second, the new logger does not implement any kind of artifical rate
limiting (what seelog refers to as "adaptive logging"). Log messages
are outputted as soon as possible and the application will appear to
perform much better when watching standard output.
Because log rotation is not a feature of the btclog logging
implementation, it is handled by the main package by importing a file
rotation package that provides an io.Reader interface for creating
output to a rotating file output. The rotator has been configured
with the same defaults that btcd previously used in the seelog config
(10MB file limits with maximum of 3 rolls) but now compresses newly
created roll files. Due to the high compressibility of log text, the
compressed files typically reduce to around 15-30% of the original
10MB file.
