This change modifies the params struct to embed a *btcnet.Params,
removing the old parameter fields that are handled by the btcnet
package.
Hardcoded network checks have also been removed in favor of modifying
behavior based on the current active net's parameters.
Not all library packages, notable btcutil and btcchain, have been
updated to use btcnet yet, but with this change, each package can be
updated one at a time since the active net's btcnet.Params are
available at each callsite.

This change adds two parameters to the Params struct which are used by
btcd to alter behavior based on the active network, rather than
hardcoding checks for a particular network.
The first, ResetMinDifficulty, specifies whether the target difficulty
can change between the retarget intervals.
The second, RelayNonStdTxs, specifies whether standard transaction
checks should not be performed when accepting mempool transactions.
The zero values (false) for both of these bools are the correct
parameter values for mainnet.
While here, rename the test network version 3 to "testnet3", as both
btcd and btcwallet will include additional handling to rename this to
"testnet" for directory names, and a switch to "testnet3" is planned
in the future.
The btcutil package recently exposed a WIF type to provide more
functionality and simplify working with WIF strings. This commit changes
the DumpPrivKey and ImportPrivKey RPCs to use the new WIF type.
There are several RPCs which accept a pointer to a hash, transaction,
block, etc. Previously not all RPCs handled being passed a nil pointer
consistently.
Closes#4.
PushedData returns an array of byte slices containing any pushed data
found in the passed script. This includes OP_0, but not OP_1 - OP_16.

- Keep comments to 80 cols for consistency with the rest of the code base
- Made verify a method off of Signature instead of PublicKey since one
verifies a signature with a public key as opposed to the other way
around
- Return new signature from Sign function directly rather than creating a
local temporary variable
- Modify a couple of comments as recommended by @owainga
- Update sample usage in doc.go for both signing messages and verifying
signatures
ok @owainga
This change removes the internal pad function in favor a more opimized
paddedAppend function. Unlike pad, which would always alloate a new
slice of the desired size and copy the bytes into it, paddedAppend
only appends the leading padding when necesary, and uses the builtin
append to copy the remaining source bytes. pad was also used in
combination with another call to the builtin copy func to copy into a
zeroed byte slice. As the slice is now created using make with an
initial length of zero, this copy can also be removed.
As confirmed by poking the bytes with the unsafe package, gc does not
zero array elements between the len and cap when allocating slices
with make(). In combination with the paddedAppend func, this results
in only a single copy of each byte, with no unnecssary zeroing, when
creating the serialized pubkeys. This has not been tested with other
Go compilers (namely, gccgo and llgo), but the new behavior is still
functionally correct regardless of compiler optimizations.
The TestPad function has been removed as the pad func it tested has
likewise been removed.

This commit adds logic to track all registered notifications that have
been registered by the client in a notification state when the default
automatic reconnect is enabled.
The notification state is then used to reregister for all previously
registered notifications on reconnect. This allows the caller to
continue receiving notifications across reconnect cycles.
Also, since the new package exposes more connection related error
information, add a new ErrInvalidEndpoint which is returned if the
specified enpoint does not appear to be a valid websocket provider and
only return the ErrInvalidAuth error when HTTP authorization failure
status codes are detected.
Closes#1.
Since the example illustrates callbacks for the OnBlockConnected and
OnBlockDisconnected callbacks, also register for the notifications with
NotifyBlocks.
While here, document the fact that most of the callbacks require
registration.
Ordinarily, getwork will return an error if btcd is not connected to any
other peers. This commit relaxes that requirement when running in
regression test mode since it is useful for development purposes.
While here, also improve check which returns an error from getwork is not
current to exclude the check when the best chain height is zero since the
code never believes it is current when at height 0.
This commit adds a full suite tests for the new reject message added in
protocol version 70002 to bring the overall test coverage of btcwire back
up to 100%.
Closes#9.
This commit adds the new reject protocol message added to recent versions
of the reference implementation. This message is intended to be used in
response to messages from a remote peer when it is rejected for some
reason such as blocks being rejected due to not conforming to the chain
rules, transactions double spending inputs, and version messages sent
after they're already sent.
This is work toward issue #9.
- Correct MsgFilterLoad max payload
- Enforce max flag bytes per merkle block
- Improve and finish tests to include testing all error paths
- Add fast paths for BloomUpdateType
- Convert all byte fields to use read/writeVarBytes
- Style and consistency updates
- README.md and doc.go updates
Closes#12.
