This commit introduces an HDPrivateKeyID and HDPublicKeyID field to the
params struct which are used by hierarchical deterministic extended keys
as defined by BIP0032.
In addition, a new function named HDPrivateKeyToPublicKeyID has been added
to allow the caller to get the associated public key ID given a private
key ID.
The tests have also been updated to maintain 100% test coverage.

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.
Although it is possible to get the command name for each msg type by
creating an instances of the type and calling the Command method against
it, it's slightly more efficient to simply allows callers to have direct
access to the exported constants.
This is currently really useful for the reject message since callers need
to be able to examine the command type to determine whether or not the
hash field needs to be included.
This commit splits the two rule validation errors related to the timestamp
being too old into two distince errors rather than grouping them under the
same one. Thus there is now a new ErrCheckpointTimeTooNew in addition to
the existing ErrTimeTooNew error.
This allows the caller to detect the when a block is rejected due to a
time-related checkpoint failure whereas before the combined error did not.
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 adds the Move, MoveAsync, MoveMinConf, MoveMinConfAsync,
MoveComment, and MoveCommentAsync functions for issuing the "move" RPC
with various optional parameters.
Closes#16.
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.

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.
This commit adds an example test file so it integrates nicely with Go's
example tooling.
This allows the example output to be tested as a part of running the
normal Go tests to help ensure it doesn't get out of date with the code.
It is also nice to have the example in one place rather than repeating it
in doc.go and README.md.
Links and information about the example have been included in README.md in
place of the example.
It seems the godoc example extraction does not recognize the same syntax
used for functions with receivers when working with interfaces.
So, instead, categorize the example on the interface.
