This allows the provision of address/port pairs to be listened on instead
of just providing the port. e.g.:
btcd --listen 1.2.3.4:4321 --listen 127.0.0.01 --listen [::1]:5432
When --proxy and --connect are used, we disable listening *unless* any --listen
arguments have been provided, when we will listen on those addresses as
requested.
Initial code by davec, integration by myself.
Closes#33
allow listens to fail, but warn. error if all failed
fmt
So far we only do level 0 and level 1 checks (precense and basic
sanity). The checks done at higher levels in bitcoind are closely
coupled with their database layout.
arguably Closes#13
This change allows wallet to record all transactions in a block before
receving the new block notification, and then process them all
together when the blockconnected notification arrives.
Previously, RemoveMinedTxRequest was being run from a caller which
held a reader lock for the websocket request contexts. When
RemoveMinedTxRequest tried to grab a writer lock, it would block.
This change creates a new function, removeMinedTxRequest, that does
not grab any locks, and the caller (NotifyBlockConnected) grabs a
writer lock instead of a reader lock.
Previously, on a blockconnected notification, the websocket context
reader lock was not always being given up properly. This change
defers the unlock so it will always happen.
This fixes an issue where wallet will stop responding (due to not
being able to complete its handshake) on reconnect.
This commit makes use of the new btcutil.AppDataDir function which chooses
appropriate data directories for each supported operating system. It also
adds code to the upgrade path to properly migrate existing data from the
old to new locations.
This is part of work toward issue #30.
This change reworks where the command parsing occurs to be done before
handlers are checked. Before, the websocket extension handler called
the standard handler with the same message, and if it was unhandled,
would unmarshal it a second time for checking extension handlers.
persistentpeers and outbound(nonpersistent) peers get their own lists,
so iterating over them can be much simpler (and quicker when you have
125 peer of which 8 are outbound).
Redo the datastructures we search so that we only do one lookup per txin and
txout instead of doing a loop per wallet connection.
Don't send spent data on tx notifications, this can be worked out in wallet and
it is expensiveish to calculate. However we DO check upon getting a notification
request if the output is already spent, and in which case we send an immediate
notification to force a rescan.
MinedTxNotfications are handled separately to the connected block messages
largely to enable this to scale rather better.
Tested by jrick (who found one bug i had introduced, thanks!)
Additionally (accidentally squashed in):
Add handlers for all known commands.
We have handlers for all wallet-requiring commands that will return a suitable
error.
Unimplemented commands temporarily return an error stating so.
This change allows map lookups using address hashes (which are
returned as []byte) instead of either copying the hash into an array,
or doing a bytes.Equal().
A stupid range over a map until the right key is found was also just
changed to a single map lookup.
This adds to the initial rescan implementation, but switches it to
rescan based on a group of addresses, rather than just one. Due to
how expensive database lookups are during a rescan, wallets should
take advantage of this to rescan once for all needed addresses for all
accounts.
This commit changes the various cases that were serializing transactions
into a buffer and taking the length to use the new faster SerializeSize
API. It also completes a TODO since the serialized size of a transaction
output is now available.
Rather than showing all errors from ProcessTransaction as an error, check
if the error is a TxRuleError meaning the transaction was rejected as
opposed to something actually going wrong and log it accordingly.
Looking up transactions from the database is an expensive operation.
This commit modifies the NotifyNewTxListener code to simply iterate the
transactions in the block instead of looking them up from the db.
Currently the wallet code needs a spent flag which ultimately shouldn't be
required. For now, the spent data is simply created on the fly which is
still significantly faster than doing database transaction lookups.
Closes#24.
This change unbreaks the case where an unknown command is sent to the
RPC server. Instead of replying back with a nil JSON id, if the
initial unmarshal was successful (and thus, the message was valid
JSON-RPC), the unmarshaled id will be used in the error reply.
We have a channel for queries and commands in server, where we pass in
args and the channel to reply from, let rpcserver use these interfaces
to provide the requistie information.
So far not all of the informaation is 100% correct, the syncpeer
information needs to be fetched from blockmanager, the subversion isn't
recorded and the number of bytes sent and recieved needs to be obtained
from btcwire. The rest should be correct.
