Motivation:
With NIO 2.32.0 we broke the core NIO module up into modules that split
apart the POSIX layer and the core abstractions. As a result, this
package no longer needs to express a hard dependency on the POSIX layer.
Modifications:
- Rewrote imports of NIO to NIOCore.
- Added NIOEmbedded and NIOPosix imports where necessary in tests.
- Extended soundness script to detect NIO imports.
- Note that the main modules still depend on NIO, which is necessary
for backwards-compatibility reasons. This dependency is unused.
Result:
No need to use NIOPosix.
Motivation:
Previously, WritePCAPHandler would crash if more than 4GiB of data were
either received or sent through the same instance of the
WritePCAPHandler because of a UInt32 overflow representing the TCP
sequence/ACK numbers.
Modifications:
Make TCP sequence/ACK numbers wrap around correctly.
Result:
- now you can send/receive up to 16 EiB of data :P.
- fixes rdar://61887658
Motivation:
Especially with TLS but also without, in real production environments it
can be handy to be able to write pcap files from NIO directly.
Modifications:
add a ChannelHandler that can write a PCAP trace from what's going on in
the ChannelPipeline.
Result:
easier debugging in production
