This commit moves the ProcessBlock example to a 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normal Go tests to help ensure it doesn't get out of date with the code.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 incldued in doc.go and
README.md in place of the example.
Previously the exported Disconnect and Shutdown functions called each other
and therefore needed to release and reacquire the locks which could
potentionally allow a request to sneak in between the lock and unlock.
This commit changes the exported Shutdown function so that everything is
done under the request lock to prevent this possibility. In order to
support this, the shared code between the Disconnect and Shutdown
functions has been refactored into unexported functions and the locking
has been altered accordingly.
Also, replace the sendMessage function with a select over the send and
disconnect channels to prevent any issues with queued up messages.
joint debugging effort between myself and @jrick
Previously, requests could still be sent to a shutdown client and
added to the client's internal data structures, without ever
responding to the future with an error for a shutdown client (causing
hangs when blocking on the future receive). This change fixes this by
performing a non-blocking read of the client's shutdown channel before
adding a request, and responding with the shutdown error if the client
has begun or completed its shutdown.

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.
ok @drahn
Since the underlying database driver can now return an error when looking
up if blocks and transactions exist, the HaveBlock function now includes
an error return to allow any underlying errors to be exposed.
This ability for multiple database backends has been available for a long,
long time. Looks like this was simply not updated when the interface was
added.
These changes are a joint effort between myself and @dajohi.
- Separate IP address range/network code into its own file

- Use consistent variable casing in refactored code
- Add initial doc.go package overview
- Bump serialize interval to 10 minutes
- Correct GroupKey to perform as intended
- Make AddLocalAddress return error instead of just a debug message
- Add tests for AddLocalAddress
- Add tests for GroupKey
- Add tests for GetBestLocalAddress
- Use time.Time to improve readability
- Make address manager code golint clean
- Misc cleanup
- Add test coverage reporting
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.
This commit modifies the error handling for websocket connections to fall
back to returning the status text returned from the server if the
handshake fails and it's not due to an authentication or invalid endpoint.
This change set equips the RPC client with handling of non successful
HTTP responses. An HTTP response is considered non successful when its
status code is not in the range 200..299
This commits removes a number of golint warnings. There is a class of
warnings which I can't fix due to unsufficient knowledge of the domain
at this point. These are listed here:

The hex package requires an even number of characters in hex encoded
strings. Some of the handlers already prepended a zero if necessary to
make this condition true, however other did not. This commit extends this
functionality to all handlers and also makes the error return consistent.
ok @jrick
This commit creates and exports a new constant, MaxTimeOffsetSeconds,
which is the maximum number of seconds a block timestamp is allowed to be
ahead of the current time.
Previously this value was hard coded into the consensus rule path, however
it is useful better to have it defined as a constant and exported so other
callers can access it.
No consensus rules have been changed with this commit.
