Motivation
We have some Task error handling functions that are generic for no
apparent reason. They're also typically called from contexts where they
also report the error to the delegate, but one of the call sites doesn't
do that. So add a test for that as well.
Modifications
- Rewrite Task.fail(with:delegate:) to be non-generic.
- Add a call to the delegate error handler on the path that is missing
it.
- Add a test for that call
Results
Cleaner, easier to follow code
Motivation:
RequestBag conforms to HTTPExecutableRequest to must be Sendable.
Modifications:
- Move event-loop bound state to a loop-bound box
- Remove redundant event-loop checks (they are performed by the loop
bound box)
Result:
Fewer warnings
Trying to pave the way for closing
https://github.com/swift-server/async-http-client/issues/790 with some
direction from @Lukasa.
I have no idea where is best to insert this new delegate method. I'm
currently doing it first thing in `receiveResponseHead0`, and not using
an EventLoopFuture for back pressure management. The state machine seems
pretty fragile and I don't want to leave too much of an imprint. Trying
to be a part of an EventLoopFuture chain seems really complicated and
would really leave a mark on the codebase, so I'm wondering if it's
possible to just warn the user "do not block"?
Anyway, just a jumping-off point and happy to take direction!
Migrate CI to use GitHub Actions.
### 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.
* Disabled warnings-as-errors on Swift 6.0 CI pipelines for now.
### Result:
Feature parity with old CI.
Sometimes it can be useful to connect to one host e.g. `x.example.com` but request and validate the certificate chain as if we would connect to `y.example.com`. This is what this PR adds support for by adding a `dnsOverride` configuration to `HTTPClient.Configuration`. This is similar to curls `—resolve-to` option but only allows overriding host and not ports for now.
Motivation
When receiving certain patterns of response body parts, we can end up
recursing almost indefinitely to deliver them to the application. This
can lead to crashes, so we might politely describe it as "sub-optimal".
Modifications
Keep track of our stack depth and avoid creating too many stack frames.
Added some unit tests.
Result
We no longer explode when handling bodies with lots of tiny parts.

### Motivation
Today `didSendRequestPart` is called after a request body part has been passed to the executor. However, this does not mean that the write hit the socket. Users may depend on this behavior to implement back-pressure. For this reason, we should only call this `didSendRequestPart` once the write was successful.
### Modification
Pass a promise to the actual channel write and only call the delegate once that promise succeeds.
### Result
The delegate method `didSendRequestPart` is only called after the write was successful. Fixes#565.

### Motivation
Currently, we don’t consume the response body of redirect responses. Because of this requests, that receive a redirect response with response body, may hang indefinitely.
### Changes
- Consume redirect response body if less than 3kb
- Cancel redirect response if larger than 3kb
### Result
Redirect responses are consumed. Fixes#574
- a new `RequestOptions` struct was created, that can be used to set request specific options. It is required by the `HTTPExecutableRequest`
- Added support for `ignoreUncleanSSLShutdown` in the `HTTPRequestStateMachine` and the `HTTP1ConnectionStateMachine`. In http/2 `ignoreUncleanSSLShutdown` is always off.
- Refactored code from `TaskHandler` into new method `HTTPClient.Request.createRequestHead` that creates an `HTTPRequestHead` and matching `RequestFramingMetadata`
- Added required property `requestFramingMetadata` to `HTTPExecutingRequest`
- Added property `requestFramingMetadata` to `RequestBag`

- Adding four new protocols:
- `HTTPExecutingRequest` a protocol representing an HTTP task that is executed on a ChannelHandler.
- `HTTPScheduledRequest` a protocol representing an HTTP task that is scheduled for execution, but in a waiting state (example: Waiting for an idle connection in the connection pool).
- `HTTPRequestExecutor` a protocol that can be used from the `HTTPExecutingRequest` abstracting away functionality that will normally be implemented by a `ChannelHandler`
- `HTTPRequestScheduler` a protocol that can be used from the `HTTPScheduledRequest` abstracting away functionality that will normally be implemented by a `ConnectionPool`
- An implementation of the `HTTPExecutingTask` and `HTTPScheduledRequest` called `RequestBag`. It implements our current API using the new protocols
