The getinfo RPC method requires access to information only available in
the wallet. Therefore, it has been moved to the list of methods which
return an error information the caller to send the request to the wallet
instead.
The getnewaddress RPC method deals with wallet-related functionality and
therefore has been moved to the list of methods which return an error
information the caller to send the request to the wallet instead.
Both of these RPC methods require access to information ony available in
the wallet. Therefore they have been moved to the list of methods which
return an error information the caller to send the request to the wallet
instead.
Rather than having the iterator functions a separate entities that access
the state to iterate, just expose the iterators as receivers on the state
itself. This is more consistent with the style used throughout the code
and the other receivers on the state such as Count, OutboundCount, etc.
This commit adds full support for the getaddednodeinfo RPC command
including DNS lookups which abide by proxy/onion/tor rules when the DNS
flag is specified. Note that it returns an array of strings when the DNS
flag is not set which is different than the current version of bitcoind
which is bugged and scheduled to be fixed per issue 3581 on the bitcoind
issue tracker.
This commit improves how the legacy RPC server responds to authentication
failures so things like web browsers can react better. The following
changes have been made:
First, authentication failures were only printing the 401 error response
in the body instead of setting the http status code. This means the
response had a 200 OK header with a body of 401 Unauthorized. Therefore
the client would think everything was ok, but see the response as
malformed JSON.
Second, the spec for 401 Unauthorized responses state they must include a
WWW-Authenticate header to instruct the client how to authenticate.
Without this, browsers won't prompt the user for credentials.
The previous websocket code required HTTP auth headers to be sent in order
to use the websocket. While this makes sense for most applications, some
use cases such as javascript-based websockets from browsers do no have the
ability to send headers.
This commit modifies the authentication logic to allow an alternative
authentication mechanism when HTTP auth headers can't be sent. In
particular, it introduces a new JSON-RPC command named authenticate which
accepts the username and passphrase for the RPC server. The command is
only required if the connetion has not already been authenticated via HTTP
auth headers and it must be the first command to be received. Sending any
other command will immediately disconnect the websocket.
ok from @owainga and @jrick.
This closes#77.
This fixes two issues: first, the sendrawtransaction handler had an
extra character in the key in the websocket handler map, preventing
the handler from never running. Second, a nil pointer dereference was
removed from the handler.
This change fixes the minedtx notifications for btcwallet, since the
websocket-handler now runs instead of falling back to the legacy RPC
handler.
This commit adds the btcdb memdb backend as a supported database type.
Note that users will NOT want to run in this mode because, being memory
only, it obviously does not persist the database when shutdown.
It is being added for testing purposes to help prevent constant abuse to
developer's hard drive when churning the block database multiple times a
day.
This commit switches the handleGetHeadersMsg function to make use of the
new FetchBlockHeightBySha and FetchBlockHeaderBySha functions in btcdb.
Also, while here, nuke the header copy which is no longer required due to
the recent btcwire changes.
This commit reduces the initial idle timeout before version negotiation
has happened on a new peer to 30 seconds. Previously it could take 5
minutes due to the general idle timeout.
The websocket.Server used the by websocket.Handler type automatically adds
a handshake function which prevents connections when the Origin header is
not set. Not all clients send this information and we already require
authentication headers as the auth mechanism anyways.
The websocket package assumes binary blobs if []byte is used. Since we're
using JSON-RPC for all the websocket communications, it should be text
based.
This commit changes the websocket Send/Receive and associated channels to
strings accordingly.
This removes the last notification that was being sent unsolicited.
Since it is no longer needed, the code to duplicate notifications to
all clients has been removed.
The RPC server was performing some of the shutdown logic in the wrong
order, that is, logging the the server has shut down, waiting for all
server goroutines to finish, and then closing a channel to notify
server goroutines to stop. These three items have been reversed to
fix a hang where goroutines currently being waited on had not shut
down because they did not receive the notification.
While here, the server waitgroup was incremented for a goroutine that
was running without it, another select statement was added to stop a
duplicate close (which never occured last commit when I added the
select statements), and the "stopping rescan" logging was moved to
debug to make the ^C shutdown logging nicer.
