This ability for multiple database backends has been available for a long,
long time. Looks like this was simply not updated when the interface was
added.
These changes are a joint effort between myself and @dajohi.
- Separate IP address range/network code into its own file
- Group all of the RFC range declarations together
- Introduces a new unexported function to simplify the range declarations
- Add comments for all exported functions
- Use consistent variable casing in refactored code
- Add initial doc.go package overview
- Bump serialize interval to 10 minutes
- Correct GroupKey to perform as intended
- Make AddLocalAddress return error instead of just a debug message
- Add tests for AddLocalAddress
- Add tests for GroupKey
- Add tests for GetBestLocalAddress
- Use time.Time to improve readability
- Make address manager code golint clean
- Misc cleanup
- Add test coverage reporting
This commit does just enough to move the address manager into its own
package. Since it was not originally written as a package, it will
require a bit of refactoring and cleanup to turn it into a robust
package with a friendly API.
By putting each DNS seed in its own go routine, btcd can start connecting
to nodes as they are found instead of waiting for all seeds to respond. This
significantly speeds up startup time.
Additionally, logging was added to show how many addresses were fetched from
each seed.
BitcoinJ, and possibly other wallets, don't follow the spec of sending an
inventory message and allowing the remote peer to decide whether or not
they want to request the transaction via a getdata message. Unfortuantely
the reference implementation permits unrequested data, so it has allowed
wallets that don't follow the spec to proliferate.
While this is not ideal, this commit removes the functionality which
disconnects peers for sending unsolicited transactions to provide
interoperability.
This commit corrects an issue where the data requested by getdata was not
being properly throttled which could lead to higher than desired memory
usage on large requests.
This commit modifies the error handling for websocket connections to fall
back to returning the status text returned from the server if the
handshake fails and it's not due to an authentication or invalid endpoint.
This change set equips the RPC client with handling of non successful
HTTP responses. An HTTP response is considered non successful when its
status code is not in the range 200..299
This commits removes a number of golint warnings. There is a class of
warnings which I can't fix due to unsufficient knowledge of the domain
at this point. These are listed here:

The hex package requires an even number of characters in hex encoded
strings. Some of the handlers already prepended a zero if necessary to
make this condition true, however other did not. This commit extends this
functionality to all handlers and also makes the error return consistent.
ok @jrick
This commit creates and exports a new constant, MaxTimeOffsetSeconds,
which is the maximum number of seconds a block timestamp is allowed to be
ahead of the current time.
Previously this value was hard coded into the consensus rule path, however
it is useful better to have it defined as a constant and exported so other
callers can access it.
No consensus rules have been changed with this commit.
This commit adds a new behavior flag, BFDryRun which allows the caller
to indicate all checks should be performed against the block as normal
except it will not modify any state. This is useful to test that a block
is valid without actually modifying the current chain or memory state.
This commit also adds a few additional checks which were elided before
since they are implicitly handled by btcwire. However, with the ability
to propose blocks which didn't necessarily come through the btcwire path,
these checks need to be enforced in the chain code as well.
As a part of adding the checks, three new error codes named
ErrBlockTooBig, ErrTooManyTransactions, and ErrTxTooBig have been
introduced.
Closes#5.
This commit adds a new function named SerializeSize to the public API for
MsgBlock which can be used to determine how many bytes the serialized data would
take without having to actually serialize it. In addition, it makes the
exported BlockVersion an untyped constant as well as changes the block and
tx versions to a signed integer to more closely match the protocol.
Finally, this commit also adds tests for the new function.
The following benchmark shows the difference between using the new
function to get the serialize size for a typical block and serializing
into a temporary buffer and taking the length of it:
Bufffer: BenchmarkBlockSerializeSizeBuffer 200000 27050 ns/op
New: BenchmarkBlockSerializeSizeNew 100000000 34 ns/op
Closes#19.
There are certain cases such as getblocktemplate which allow external
callers to be repsonsible for creating their own coinbase to replace the
generated one. By allowing the pay address to be nil in such cases, the
need to specify mining addresses via --miningaddr can be avoided thereby
leaving the payment address management up to the caller.
This commit adds a new result type for the getblocktemplate RPC which
provides the fields as defined by BIP0022. The extension fields defined
by BIP0023 are not included yet.
ok @jcvernaleo
BIP0022 defines optional fields in a getblocktemplate request for long
polling and template tweaking.
In addition, for template tweaking, there are two fields, sigoplimit and
sizelimit, which are atypical in that they are allowed to be either
booleans or numeric. This requires the fields to be represented as
interfaces which means any code making use of the struct will need to use
type assertions or a type switch.
This commit updates GetBlockTemplateCmd accordingly.
ok @jcvernaleo
