Motivation:
To migrate to GitHub actions and centralised infrastructure.
Modifications:
Changes of note:
* Adopt swift-format using rules from SwiftNIO
* Remove scripts and docker files which are no longer needed
Result:
Feature parity with old CI.
Motivation:
The NIOPCAPRingBuffer can limit the number of fragment or the total
number of bytes in its buffer or both. When configuring the buffer to
limit only the maximum number of bytes it sets the maximum number of
fragments allowed to `.max`. On `init` the buffer has enough capacity
reserved to store tha maximum number of fragments.
This would be a large and potentially totally unnecessary allocation.
That is, if it didn't crash at runtime. It crashes at runtime as
`CircularBuffer` converts the requested capacity to a `UInt32` which
traps if you pass it an `Int.max`.
Modifications:
- Don't reserve capacity on init
- Adjust the test which tests the byte limit to not set a capacity as
well
Result:
- `NIOPCAPRingBuffer(maximumBytes:)` doesn't crash
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:
Capturing all packets is expensive. Recording to a ring buffer and
then outputting on a triggering event allows this cost to be reduced.
Modifications:
Add a new handler - NIOPCAPRingCaptureHandler.
This derives from the existing NIOWritePCAPHandler and generates PCAP recordings.
A ring buffer contained in this handler stores the captured packets until RecordPreviousPackets
is received as a user message at which point they are flushed to the sink.
Result:
There is a new handler capable of outputting packet captured data only in the build up to
a known event.
