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 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normal Go tests to help ensure it doesn't get out of date with the code.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.

This commit adds error returns to all of the Db interface methods except
for FetchTxByShaList and FetchUnSpentTxByShaList since they expose the
errors on each individual transaction.
It also updates all tests and code for both the leveldb and memdb drivers
for the changes.
Closes#5.
