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.
This changes the protocol between btcd and btcwallet to follow
JSON-RPC specifications sending notifications as requests with an
empty ID.
The notification request context handling has been greatly cleaned up
now that IDs no longer need to be saved when sending notifications.
This commit changes all code which deals with extracting addresses from
scripts to use the btcscript API ExtractPkScriptAddrs which in turn makes
use of the new btcutil.Address interface.
This provides much cleaner code for dealing with arbitrary script
destinations which is extensible without having to churn the APIs if new
destination types are added.
The name handlers for a package level is a bit too generic and could
easily cause a name collision. Even though the compiler would catch it,
use something a bit more descriptive.
Since the command to handler mappings are the most often modified and
referenced code in rpcserver.go and rpcwebsocket.go, move them near the
top of their respective files.
This commit cleans up the standard RPC command hanlding a bit by removing
the websocket specific notification channel from the handlers. This was
previously required because the sendrawtransaction, when called from a
websocket enabled connection, needs to add a notification for when the
transaction is mined.
This commit modifies that to instead implement a websocket extended
version of sendrawtransaction which invokes the standard handler and adds
the notification. In addition, the main send was modified to first look
if the command has a websocket specific handler first, and then falls back
to standard commands, rather than the previous approach of first checking
for a standard command and falling through to websocket commands. This
essentially allows websockets connections to extend commands with the same
name with additional functionality such as what was done in this commit.
The rpcserver.go file is starting to get a bit unwieldy. This commit
moves the separable websocket specific bits into a separate file named
rpcwebsocket.go.
Added error checking for script disassembley
Changed vout to handle errors in processing the way bitcoind does: the
type displayed is "nonstandard" when the calculated type is nonstandard
or nulltype and also when there is an error getting the address.
Still doesn't properly support multisig addresses, but now it should
return "nonstandard" since since address lookup fails for those cases.
Since the decoderawtransaction result makes use of the same vin and vout
lists, this commit also factors the logic for those out into separate
functions.
The ScriptSig field of the Vin type for TxRawResult is now a pointer in
btcjson so it can be properly omitted. This commit updates the code to
create the new ScriptSig object as needed.
The getrawtransaction RPC call should return a hex-encoded string of the
transaction when verbose is false instead of a TxRawResult object with the
Hex field set to be compatible with the Sathoshi client. This commit,
along with a recent commit to btcjson corrects this.
Also, while here, do a bit of cleanup, finish a TODO to check for an
invalid hash, and optimize the handling of non-verbose slightly.
The getblock RPC call should return a hex-encoded string of the block when
verbose is false instead of a BlockResult object with a Hex field set to
be compatible with the Sathoshi client. This commit, along with a recent
commit to btcjson corrects this.
Also, while here, move code which only applies to verbose mode after the
call which handles the non-verbose logic. This saves a few cycles since
the non-verbose logic doesn't need the extra information.
The fee field of the getrawmempool RPC JSON response should be in Bitcoins
instead of Satoshi. This commit corrects that issue.
Also, add a couple of comments and fix a comment typo while here.
This implements only the bare bones of external ip address selection
using very similar algorithms and selection methods to bitcoind. Every
address we bind to, and if we bind to the wildcard, every listening
address is recorded, and one for the appropriate address type of the
peer is selected.
Support for fetching addresses via upnp, external services, or via the
command line are not yet implemented.
Closes#35
Updated handleGetRawTransaction to populate all the fields required to
match bitcoind. It still doesn't handle MULTISIG addresses correctly.
Changed handleGetBlock to implement new optional verbose (default true)
flag and also added a verboseTx flag to return TxRawDefault instead of
Txid. When verbose=false, GetBlock returns hex-encoded wire bytes for
the block.
The vout field (as part of the getrawtransaction JSON reply) should be
set to the input's previous outpoint's index, not the current input
index.
Found by flam and reported on IRC. Thanks!
This switches a break to a continue if a txout does not include a
pay-to-pubkey-hash script type. btcwallet only supports
pay-to-pubkey-hash at the moment, and this fixes an issue where a tx
may have an different type of output, as well as pay-to-pubkey-hash,
which may be ignored by the wallet notification code.
Found by dhill.
I previously fixed the duplicate send (before seeing GH issue #54),
but forgot that btcwallet expects a nil reply when rescan has
finished. This adds the final reply back, but replies with nil.
Fixes#54.
This updates the replies for rescan and tx notifications with
additional information that is needed for wallet to properly support
the listtransactions command.
While here, drastically improve rescan performance by not looking up
every sha in rescan's block range.
Also, make every subsystem within btcd use its own logger instance so each
subsystem can have its own level specified independent of the others.
This is work towards #48.
