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.
It was pointed out in #76 that if you arrived to the Update section
of the README without seeing the Installation section, the requirement for
Go 1.2 is easy to miss. This commit builds the requirement in the
Installation section and adds it to the Updating section as well to
hopefully make it more noticable.
The addblock utility was originally written as a quick debug tool during
initial development to populate blocks into the database. However, now
that it has been designated as the standard way to import bootstrap.dat
(and indeed block data files in general), it was lacking a few features
such as properly checking against the chain rules and known good
checkpoints.
This commit reworks and improves the utility in several ways:
- Imported blocks are now checked against the chain rules including
checkpoints to ensure they match the known good chain
- The utility now properly shuts down after processing all blocks
- Attempting to import orphan blocks (blocks which build off a block you
don't yet have in the database) returns an error
- Blocks that are already known are now skipped instead of causing an
error which means you can stop and restart the import mid-way through
without issues or start it after you've already downloaded a
portion of the chain
- The block height is no longer assumed to start at 0 which means input
files that start later in the chain will work properly so long as you
already have the chain at least up to the point of the block just before
the first one in the input file
- Improved error handling and reporting
- How often the progress display is shown is now configurable
- Statistics about how many blocks were processed, imported, and already
known are now displayed after the input file has been fully processed
This resolves comments made in #60.
The warning about a missing config file should only be shown after all
other configuration has succeeded so it's not shown when there are invalid
options specified. Also add a comment about it where its intended
placement is for the future.
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 a couple of sections which deal with large lists of
inventory vectors to use the new size hint functions recently added to
btcwire. This allows a bit more efficiency since the size of the list is
known up front and we can therefore avoid dynamically growing the backing
array several times. This also helps avoid a Go bug that leaks memory on
appends and GC churn.
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.
This implements --onion (and --onionuser/--onionpass) that enable a
different proxy to be used to connect to .onion addresses. If no main
proxy is supplied then no proxy will be used for non-onion addresses.
Additionally we add --noonion that blocks connection attempts to .onion
addresses entirely (and avoids using tor for proxy dns lookups).
the --tor option has been supersceded and thus removed.
Closes#47
This commit modifies the new valid peer message to display the useragent.
Previously this information was only available by setting the PEER
subsystem debuglevel to debug or lower.
This was prompted by #64.
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.
