Motivation:
HTTP is a plaintext protocol which means that someone may be able
to eavesdrop the data. To prevent this, HTTPS should be used whenever
possible. However, maintaining using https:// in all URLs may be
difficult. The nohttp tool can help here. The tool scans all the files
in a repository and reports where http:// is used.
Modifications:
- Added nohttp (via checkstyle) into the build process.
- Suppressed findings for the websites
that don't support HTTPS or that are not reachable
Result:
- Prevent using HTTP in the future.
- Encourage users to use HTTPS when they follow the links they found in
the code.
Motivation:
We need to ensure we not leak in tests. We did see some leaks reported related to HaProxyMessageEncoderTest on our CI.
Modifications:
- Use readSlice(...) and so not create new ByteBuf instances that need to be released
Result:
No more leaks
Motivation:
Add support for HAProxyMessageEncoder.
This should help java based HAProxy server implementations propagate proxy information.
Modification:
Add public constructors for `HAProxyMessage`, `HAProxyTLV`, `HAProxySSLTLV`.
Add additional argument checks for `HAProxyMessage` and modify exceptions thrown when creating via public constructors directly.
Introduce a `@Sharable` `HAProxyMessageEncoder` which encodes a `HAProxyMessage` into a byte array.
Add an example `HAProxyServer` and `HAProxyClient` to `io.netty.example`
Result:
Fixes#10164
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
