The commit reworks the server statup and shutdown sequence to ensure the
server can always shutdown cleanly. The peer code depends on being able
to send messages to the address and block managers, so they need to have
their lifecycle tied to the peer handler to prevent issues with
asynchronous shutdown order.
Although not required if the proxy set is indeed Tor, setting this option
does the following:
- Sends DNS queries over the Tor network (during dns seed lookup). This
stops your IP from being leaked via DNS.
- Does not disable the listening port. This allows the hidden services
feature of Tor to be used.
Previously, the genesis block was only inserted when the database was
created, but it's possible due to rollback that the database is created
and the genesis block insert gets rolled back if the app is existed too
quickly. This commit modifies the logic to test the need for the genesis
block any time the database is loaded and insert it if necessary.
This function is a convenience method to create a new NetAddress
from a net.IP and uint16 port as opposed to a net.Addr which must be of
type *net.TCPAddr. This allows callers to support connection types that
don't provide access to a concrete *net.TCPAddr implementation.
This commit provide support for a new nolisten option which disables
listening for incoming connections. It also disable listening when the
--connect option is used.
This commit disables the RPC server by default if no RPC username of
password is specified (either via the command line or through the config
file).
Closes#2.
This commit implements support for listening on multiple sockets and
changes the default listen code to use one socket per address family (IPv4
and IPv6).
In addition, it changes the default listen binding for the RPC server to
localhost so only local clients can connect to it.
There need to be several options added to allow customization of these
settings and those will be in future commits.
Fixes#3.
This commit updates the calls into btcutil, btcscript, and btcwire for the
latest API changes which remove the need for the protocol version for
serialization and deserialization of blocks and transactions.
This commit updates the calls into btcutil and btcwire for the latest API
changes which remove the need for the protocol version for serialization
and deserialization of blocks and transactions.
This commit modifies the code to no longer require a protocol version. It
does this by making use of the new Serialize function in btcwire.
Unfortuantely this does entail a public API change which I generally don't
like to do, but eliminating the usage of the protocol version throughout
the codebase was important enough to warrant the change.
Both of these depend on the serialized bytes which are dependent on the
version field in the block/transaction. They must be independent of the
protocol version so there is no need to require it.
This commit introduces two new functions for MsgBlock and MsgTx named
Serialize and Deserialize. The functions provide a stable mechanism for
serializing and deserializing blocks and transactions to and from disk
without having to worry about the protocol version. Instead these
functions use the Version fields in the blocks and transactions.
These new functions differ from BtcEncode and BtcDecode in that the latter
functions are intended to encode/decode blocks and transaction from the
wire which technically can differ depending on the protocol version and
don't even really need to use the same format as the stored data.
Currently, there is no difference between the two, and due to how
intertwined they are in the reference implementaiton, they may not ever
diverge, but there is a difference and the goal for btcwire is to provide
a stable API that is flexible enough to deal with encoding changes.
Fix error returns in InsertBlock and FetchBlockBySha
Give up on return by name in InsertBlock() and return explicit
err one location in FetchBlockBySha to return proper error value
This commit adds a new optional function named GenerateInitialIndex. It
generates the required number of initial block nodes in an optimized
fashion. Since the memory block index is sparse and previous nodes are
dynamically loaded as needed, this function is not stricty needed.
However, during initial startup (when there are no nodes in memory yet),
dynamically loading all of the required nodes on the fly in the usual way
is much slower than preloading them.
The recent pruning code made the parent hash for a node available directly
as a field in the node. Make use of this in the getPrevNodeFromNode
function to avoid having to load the full block data associated with the
node to get the parent hash.
