Rather than using bytes.NewBuffer, which is a read/write entity
(io.ReadWriter), use bytes.NewReader which is only a read entitiy
(io.Reader) in all cases where it is possible. Benchmarking shows it's
slightly faster and it's also technically more accurate since it ensures
the data is read-only.
There are a few cases where bytes.NewBuffer must still be used since a
buffer with a known length is required for those instances.
This commit adds a full suite tests for the new reject message added in
protocol version 70002 to bring the overall test coverage of btcwire back
up to 100%.
Closes#9.
* Introduced common methods readVarBytes, writeVarBytes.
* Added type Alert which knows how to deserialize
the serialized payload and also serialize itself back.
* Updated MsgAlert BtcEncode/BtcDecode methods to handle the
new Alert.
* Sane limits are placed on variable length fields like SetCancel
and SetSubVer
the new function AddUserAgent adds the user agent to the stack
and formats it as per BIP 0014
e.g: "/btcwire:0.1.4/myclient:1.2.3(optional; comments)/"
the validation on UserAgent has been moved to a new function
validateUserAgent
This commit adds two new funtions named ReadMessageN and WriteMessageN
which return an additional paramter for the number of bytes read or written,
respectively.
It also adds tests to ensure the number of bytes read and written are the
expected values both for successful reads/writes and unsuccessful ones.
Closes#6.
This commit changes MsgBlock to enforce a 1MB max payload per the spec.
Previously it was only limited to the max overall message size. While
here, also enforce max payloads per message type (instead of only the max
overall message payload) when writing messages.
