Calling Bytes() on a big.Int strips any leading padding zeros. This
change fixes the test to always pad the byte slice for a private key
to a length of 32.
This commit modifies all code paths which work with transaction result
objects to use the concrete ListTransactionsResult provided by the btcjson
package. This provides nicer marshalling and unmarshalling as well as
access to properly typed fields.
- Instead of returning a special constructed type whenever queries for an
address. Return the internal object with an immutable external
interface.
- Make the private key gettable from PubKeyAddress to prevent having to look up
multiple times to get information from the same structure
- Enforce addresses always have public keys.
This change takes advantage of the RawMessage type in the
encoding/json package to defer unmarshaling of all JSON-RPC values
until absolutely necessary.
This is particularly important for request passthrough when btcwallet
must ask btcd to handle a chain request for a wallet client. In the
previous code, during the marshal and unmarshal dance to set the
original client's request id in the btcd response, large JSON numbers
were being mangled to use (scientific) E notation even when they could
be represented as a integer without any loss of precision.
- Move the MarkAddresForAccount and LookupAccountByAddress functionality
into account maanger.
- Move the wallet opeing logic into account manager (the only place that calls
it) and unexport.
- Move accountHandler to using a single channel for commands. Many of
the commands have ordering restraints (add account, list all accounts,
remove account, access account, mark account for address) which are very
much undefined with the multi-channel model.
- Rework all callers of LookupAccountByAddress to get the account structure
directly.
This change fixes the reply for listunspent to return a JSON object in
the same format as done by the reference implementation. Previously,
listunspent would return an array of the same objects as returned for
listtransactions.
This change adds a notification handler for the new rescanprogress
notification and takes advantage of the recent rescan manager and
partial syncing support to mark addresses as partially synced. If the
network connection to btcd is lost or wallet is restarted during a
rescan, a new rescan will start at the earliest block height for any
wallet address, taking partial syncs into consideration.
This change reappropriates the unused `last block` field from Armory's
wallet format to hold the block chain height for a partially synced
address, that is, an address that has been partially synced to
somewhere between its first seen block and the most recently seen
block. The wallet's SyncHeight method has been updated to return
partial heights as well.
The actual marking of partially unsynced address from a rescan
progress update is not implemented yet.
Recent btcd versions only allow one rescan to run at any given time
per websocket client. To better handle this, a new set of goroutines
are started by the account manager which batch and serialize rescan
jobs.
If no rescans are currently running, a new rescan starts. If a rescan
is already being processed, the request is queued and runs after the
current rescan finishes. For any additional incoming requests before
the current rescan finishes, the requests are merged with the
currently-waiting request so both can be handled with a single rescan.
This change also prepares for rescan progress notifications from btcd,
but are still unhandled until the necessary details for
partially-synced addresses are added to the wallet file format.
Calling the Bytes method for a big.Int does not pad the result to
required size for EncodePrivateKey. This change adds the leading
padding, preventing seemingly-random "malformed private key" errors
from being returned to users of dumpprivkey.
The select statement does not guarantee selecting a better case if one
might panic for sending to a closed channel. This case was hit during
client disconnect due to having multiple senders on a single channel
with one of the senders closing the chan to notify the next goroutine
to finish. This change gives each writes its own unique channel to
prevent this error.
Just like btcd, this commit adds support for the authenticate request
allowing clients unable to set the HTTP Authorization header to
authenticate to use the RPC server. The rules for the authenticate
request are as follows:
1) Authentication make clients stateful. Clients may either be flagged
as authenticated or unauthenticated.
2) Clients may authenticate by exactly one of two possible ways,
either by setting the Authorization header or by sending a JSON-RPC
authenticate request as follows:
{
"jsonrpc":"1.0",
"id":0,
"method":"authenticate",
"params":["rpcuser", "rpcpass"]
}
3) When not authenticated by the Authorization header, the first request
must be an authenticate request.
4) Sending an authenticate request after a client has already
successfully authenticated (either by the Authorization header or a
previous authentication request) is invalid.
5) The result used in the response to a successful authenticate request
is a JSON null. For any unsuccessful or invalid authenticate
requests, the connection is terminated.
This change also orders all incoming requests for a client. This was
required to ensure that any authentication requests are processed
first.
Now using w.IsLocked() for all instances of above.
Also changed one other place where the logic had to be reversed
in nextChainedAddress (len(w.secret) == 32 was the condition).
This change slightly improves the goroutines managing sends and
receives for a btcd connection by improving the logging (logging the
exact errors that caused the connection to be lost) as well as
cleaning up the shutdown handling by closing the websocket connection
for any fail and closing the response channel when no more responses
can be read.
The private key import codepath (called when handling the
importprivkey RPC method) was not triggering rescans for the imported
address. This change begins a new rescan for each import and adds
additional logic to the wallet file to keep track of unsynced imported
addresses. After a rescan on an imported address completes, the
address is marked as in sync with the rest of wallet and future
handshake rescans will start from the last seen block, rather than the
import height of the unsynced address.
While here, improve the logging for not just import rescans, but
rescanning on btcd connect (part of the handshake) as well.
Fixes#74.
