The getinfo RPC method requires access to information only available in
the wallet. Therefore, it has been moved to the list of methods which
return an error information the caller to send the request to the wallet
instead.
The getnewaddress RPC method deals with wallet-related functionality and
therefore has been moved to the list of methods which return an error
information the caller to send the request to the wallet instead.
Both of these RPC methods require access to information ony available in
the wallet. Therefore they have been moved to the list of methods which
return an error information the caller to send the request to the wallet
instead.
Rather than having the iterator functions a separate entities that access
the state to iterate, just expose the iterators as receivers on the state
itself. This is more consistent with the style used throughout the code
and the other receivers on the state such as Count, OutboundCount, etc.
This commit adds full support for the getaddednodeinfo RPC command
including DNS lookups which abide by proxy/onion/tor rules when the DNS
flag is specified. Note that it returns an array of strings when the DNS
flag is not set which is different than the current version of bitcoind
which is bugged and scheduled to be fixed per issue 3581 on the bitcoind
issue tracker.
The getaddednode command dns flag alters the output. It is a JSON object
when true and a slice of strings containing the addresses when false.
Note there is a bug in bitcoind as of version 0.8.6 which returns the
addresses as a JSON object with duplicate keys. This has been reported as
issue 3581 on the bitcoind issue tracker.
This commit allows the result for getaddednodeinfo to be either the JSON
object or the string slice.
The createencryptedwallet extension RPC request should not be used to
create wallets for additional accounts. Instead, all btcwallet
accounts should use the same passphrase as the default account's
wallet. This change removes the account name and description
parameters from createencryptedwallet, as it will only be used to
create the default account.
This commit improves how the legacy RPC server responds to authentication
failures so things like web browsers can react better. The following
changes have been made:
First, authentication failures were only printing the 401 error response
in the body instead of setting the http status code. This means the
response had a 200 OK header with a body of 401 Unauthorized. Therefore
the client would think everything was ok, but see the response as
malformed JSON.
Second, the spec for 401 Unauthorized responses state they must include a
WWW-Authenticate header to instruct the client how to authenticate.
Without this, browsers won't prompt the user for credentials.
The previous websocket code required HTTP auth headers to be sent in order
to use the websocket. While this makes sense for most applications, some
use cases such as javascript-based websockets from browsers do no have the
ability to send headers.
This commit modifies the authentication logic to allow an alternative
authentication mechanism when HTTP auth headers can't be sent. In
particular, it introduces a new JSON-RPC command named authenticate which
accepts the username and passphrase for the RPC server. The command is
only required if the connetion has not already been authenticated via HTTP
auth headers and it must be the first command to be received. Sending any
other command will immediately disconnect the websocket.
ok from @owainga and @jrick.
This closes#77.
This fixes two issues: first, the sendrawtransaction handler had an
extra character in the key in the websocket handler map, preventing
the handler from never running. Second, a nil pointer dereference was
removed from the handler.
This change fixes the minedtx notifications for btcwallet, since the
websocket-handler now runs instead of falling back to the legacy RPC
handler.
This commit adds the btcdb memdb backend as a supported database type.
Note that users will NOT want to run in this mode because, being memory
only, it obviously does not persist the database when shutdown.
It is being added for testing purposes to help prevent constant abuse to
developer's hard drive when churning the block database multiple times a
day.
The specific parameters required by a backend is better left up to the
backend itself. For example memdb has no need for a database path, while
ldb does. This commit modifies the OpenDB and CreateDB functions to take
a arbitrary arguments which are passed along to the driver. The driver is
expected to verify the correct type and number of arguments and error
accordingly.
The existing backends have been updated accordingly.
This commit prunes several unused functions from the Db interface and the
underlying implementations. For the most part these are holdovers from
the original sqlite implementation. It also removes the types associated
with those functions since they are no longer needed. The following
functions and types have been removed:
- InvalidateCache
- InvalidateBlockCache
- InvalidateTxCache
- SetDBInsertMode
- InsertMode type and associated constants
- NewIterateBlocks
- BlockIterator interface
The reasons for removing these are broken out below.
- Neither of two current implementations implement these functions nor
does any of the fully functional code using the interface invoke them.
- After contemplating and testing caching of blocks and transactions at
this layer, it doesn't seem to provide any real benefit unless very
specific assumptions about the use case are made. Making those
assumptions can make other use cases worse. For example, assuming a
large cache is harmful to memory-constrained use cases. Leaving it up
to the caller to choose when to cache block and transactions allows much
greater flexibility.
- The DB insert mode was an artifact of the original sqlite implementation
and probably should have only been exposed specifically on the
implementation as opposed through generic interface. If a specific
implementation wishes to provide functionality such as special modes,
that should be done through type assertions.
This commit changes the node index creation to use block headers instead
of full blocks. This speeds up the initial node index generation since it
doesn't require loading a bunch of full blocks at startup.
This commit modifies local variables that are used for more convenient
access to a block's header to use pointers. This avoids copying the
header multiple times.
This commit switches the handleGetHeadersMsg function to make use of the
new FetchBlockHeightBySha and FetchBlockHeaderBySha functions in btcdb.
Also, while here, nuke the header copy which is no longer required due to
the recent btcwire changes.
