This commit builds on the recent limiter updates. The recent changes
introduced a new function named calcTxFee which could easily be confused
with calculating the fees of the transaction rather than its intended
purpose of calculating the minimum transaciton relay fee.
Rather than taking that approach, this commit instead renames the existing
function to calcMinRequiredTxRelayFee and uses a consistent variable name
for the serialized size of a transaction. It then moves the check for
whether or not the check should be applied based on the serialized size of
the transcation and block priority to the call site.
This approach also has the benefit of avoiding two calls to the
calculation function since it's a local at the call site.

Before, btcd was rate limiting all transactions that had a minimum
fee of zero. Now, btcd only rate limits transactions that contain
a fee less than the calculated fee based on size.
Closes#163
This ensures we backoff when reconnecting to peers for which we don't
understand the replies, just like we do for peers we fail to connect to.
Closes#103
The notification queue used for websocket client notifications had a
bug which caused the next queued item in some situations to not be
sent, but instead send a previously sent item. This change fixes this
by setting the 'next' variable to the next item which must be
dequeued, if the queue length is non-zero.
This bug did not always manifest itself as if the receiving goroutine
was ready, a queued item could be sent directly to it rather than
waiting in the queue to be sent at a later time.
This change modifies the behavior of the gettxout RPC to match the
behavior of the reference client. If a transaction output is spent by
a mined transaction, the handler will now return nil (JSON null).
While here, avoid indexing some slices multiple times, by creating a
local variable instead.
The sync.atomic requires alignment of variables used atomically on ARM.
This commit moves the connected and disconnect variables in the peer
struct up so they are aligned.
Fixes#157.
This commit prevents a race that could happen on shutdown if a sigint was
received between adding the first the interrupt handler and and future
handlers. This code is loosely based on initial pull request #154 which
was not accepted due to introducing a race of its own.
Thanks to @tuxcanfly for the intial pull request and finding the issue.
Rather than showing the usage when an error is encounted during options
parsing, show a message that describes how to invoke help instead. This
is useful because the help is long enough now that the error is often
overlooked since it scrolls out of view.

This commit implements reject handling as defined by BIP0061 and bumps the
maximum supported protocol version to 70002 accordingly.
As a part of supporting this a new error type named RuleError has been
introduced which encapsulates and underlying error which could be one of
the existing TxRuleError or btcchain.RuleError types.
This allows a single high level type assertion to be used to determine if
the block or transaction was rejected due to a rule error or due to an
unexpected error. Meanwhile, an appropriate reject error can be created
from the error by pulling the underlying error out and using it.
Also, a check for minimum protocol version of 209 has been added.
Closes#133.
The done and wait channels used to throttle outgoing data are being used
as semaphores. As mentioned in the previous commit, it's more efficient
to use a 0-byte type and allow compiler optimizations for the specific use
case.
This commit implements a portion of the mutations section of BIP0023.
In particular, it adds the mutable, mintime, maxtime, and noncerange keys
to the returned block template along with indicating support for the time,
transactions/add, prevblock, and coinbase/append mutations. Also, the
addition of the mintime and maxtime fields imply support for the
time/decrement and time/increment mutations. Further, if the caller
indicates the coinbasevalue capability, the coinbasetxn field will be
omitted thereby implying support for the coinbase and generation
mutations.
Closes#124.
This commit implements the long polling portion of the getblocktemplate
RPC as defined by BIP0022. Per the specification, each block template is
returned with a longpollid which can be used in a subsequent
getblocktemplate request to keep the connection open until the server
determines the block template associated with the longpollid should be
replaced with a new one.
This is work towards #124.
This commit implements the non-optional and template tweaking support for
the getblocktemplate RPC as defined by BIP0022. This implementation does
not yet include long polling support.
This is work towards #124.
This commit implements full support for filtering based on the filterload,
filteradd, filterclear, and merkleblock messages introduced by BIP0037.
This allows btcd to work seamlessly with SPV wallets such as BitcoinJ.
Original code by @dajohi. Cleanup, bug fixes, and polish by @davecgh.
This commit has no effect on the effective functionality since Go
automatically deferences pointers, but there is no reason to have a
double indirection when returning the reply for getmininginfo.
These changes are a joint effort between myself and @dajohi.

This commit does just enough to move the address manager into its own
package. Since it was not originally written as a package, it will
require a bit of refactoring and cleanup to turn it into a robust
package with a friendly API.
By putting each DNS seed in its own go routine, btcd can start connecting
to nodes as they are found instead of waiting for all seeds to respond. This
significantly speeds up startup time.
Additionally, logging was added to show how many addresses were fetched from
each seed.
BitcoinJ, and possibly other wallets, don't follow the spec of sending an
inventory message and allowing the remote peer to decide whether or not
they want to request the transaction via a getdata message. Unfortuantely
the reference implementation permits unrequested data, so it has allowed
wallets that don't follow the spec to proliferate.
While this is not ideal, this commit removes the functionality which
disconnects peers for sending unsolicited transactions to provide
interoperability.
This commit corrects an issue where the data requested by getdata was not
being properly throttled which could lead to higher than desired memory
usage on large requests.
