This commit contains several changes needed to update the client to use
the latest version of btcjson. In addition, it contains a couple of other
minor changes along the way.
While the underlying changes are quite large, the public API of this
package is still the same, so caller should generally not have to update
their code due to that. However, the underlying btcjson package API has
changed significantly. Since this package hides the vast majority of that
from callers, it should not afffect them very much. However, one area in
particular to watch out for is that the old btcjson.Error is now
btcjson.RPCError, so any callers doing any type assertions there will need
to update.
The following is a summary of the changes:
- The underlying btcjson significantly changed how commands work, so the
internals of this package have been reworked to be based off of requests
instead of the now non-existant btcjson.Cmd interface
- Update all call sites of btcjson.New<Foo>Cmd since they can no longer
error or take varargs
- The ids for each request are part of the request now instead of the
command to match the new btcjson model and are strict uint64s so type
assertions are no longer needed (slightly improved efficiency)
- Remove the old temporary workaround for the getbalance command with an
account of "*" since btcwallet has since been fixed
- Change all instances of JSONToAmount to btcutil.NewAmount since that
function was removed in favor of btcutil.Amount
- Change all btcws invocations to btcjson since they have been combined
Also update to use the new container-based builds
For now, golint has been disabled since it fails due to wanting
HTTPPostMode. This change will be made as a part of the upgrade to use
btcjson2 since it involves an API change.
This commit adds the Move, MoveAsync, MoveMinConf, MoveMinConfAsync,
MoveComment, and MoveCommentAsync functions for issuing the "move" RPC
with various optional parameters.
Closes#16.
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.
ok @davecgh
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
The string needs to be unmarshaled rather than returned directly otherwise
it will have an extra set of quotes plus it's safter to properly unmarshal
it.
