Motivation:
In line base decoders, lines are split by delimiter, but the delimiter may be \r\n or \r, so in decoding, if findEndOfLine finds delimiter of a line, the length of the delimiter may be 1 or 2, instead of DELIMITER_LENGTH, where the value is fixed to 2.
The second problem is that if the data to be decoded is too long, the decoder will discard too long data, and needs to record the length of the discarded bytes. In the original implementation, the discarded bytes are not accumulated, but are assigned to the currently discarded bytes.
Modification:
Modifications:
Dynamic calculation of the length of delimiter.
In discarding mode, add up the number of characters discarded each time.
Result:
Correctly handle all delimiters and also correctly handle too long frames.
Motivation:
HAProxyMessage should be released as it contains a list of TLV which hold a ByteBuf, otherwise, it may cause memory leaks.
Modification:
- Let HAProxyMessage extend AbstractReferenceCounted
- Adjust tests.
Result:
Fixes#9201
Motivation:
The current PROXY protocol implementation does not have support for optional Type-Length-Value fields. This pull requests adds the TLV values as specified in the PROXY protocol specification (http://www.haproxy.org/download/1.5/doc/proxy-protocol.txt) and adds support for arbitrary TLVs.
Modifications:
The existing HAProxyMessage implements an additional TLV reading operation. A small bug in the AF_UNIX reader which didn’t set the reader index correctly was also fixed.
Result:
The PROXY protocol supports TLVs
Motivation:
Sometimes it is useful to detect if a ByteBuf contains a HAProxy header, for example if you want to write something like the PortUnification example.
Modifications:
- Add ProtocolDetectionResult which can be used as a return type for detecting different protocol.
- Add new method which allows to detect HA Proxy messages.
Result:
Easier to detect protocol.
- Convert constant classes to enum
- Rename HAProxyProtocolMessage to HAProxyMessage for simpilicity
- Rename HAProxyProtocolDecoder to HAProxyMessageDecoder
- Rename HAProxyProtocolCommand to HAProxyCommand
- Merge ProxiedProtocolAndFamity, ProxiedAddressFamily, and
ProxiedTransportProtocol into HAProxiProxiedProtocol and its inner
enums
- Overall clean-up
