Motivation
The RequestBag intermediates between two different threads. This means
it can get requests that were reasonable when they were made but have
been superseded with newer information since then. These generally have
to be tolerated.
Unfortunately if we received a request to resume the request body stream
_after_ the need for that stream has been invalidated, we could hit a
crash. That's unnecessary, and we should tolerate it better.
Modifications
Tolerated receiving requests to resume body streaming in the finished
state.
Result
Fewer crashes
Fixes#576
### Motivation
If we follow a redirect which changes the origin e.g. from `127.0.0.1` to `localhost` we didn't change the `Host` header to the appropriate new origin and port combination.
### Changes
Use the original request which does not include the host instead of the prepared request to form a new request to the redirect URL.
### Alternatives
If the user defines a `Host` header themselves on the original `HTTPClientRequest` we currently never touch it, even in the redirect case. Maybe we should change our strategy and do one of the following:
1. We could always override the user defined `Host` header
2. We could only remove the user defined `Host` header on redirect and set it to the new origin and port combination
Swift tools version 5.3 and higher (the version that is specified at very top of a Package.swift file) excludes folders with a dot in the name by default. It luckily produces a warning "found 1 file(s) which are unhandled; explicitly declare them as resources or exclude from the target". However, this issue is buried under a lot of missing types Errors because of the 3 excluded files.
I run into this issue and it took me some time to figure out what the actual problem was. As we will eventually move from 5.2 to 5.3 we can already save the next person some time by resolving this issue now.
### Motivation
With Xcode 13.2, and therefore Swift 5.5.2, Swift Concurrecy is supported on older Apple OSs. async/await suport will no longer be available on Swift before `5.5.2` but this isn't a breaking change because we have not yet made anything of it public.
### Changes
- replace all `#if compiler(>=5.5) && canImport(_Concurrency)` with `#if compiler(>=5.5.2) && canImport(_Concurrency)`
- replace all `available(macOS 12.0, iOS 15.0, watchOS 8.0, tvOS 15.0, *)` with `available(macOS 10.15, iOS 13.0, watchOS 6.0, tvOS 13.0, *)`
* Fix HTTP1 to HTTP2 migration while shutdown is in progress
### Motivation
Calling `HTTPClient.shutdown()` may never return if connections are still starting and one new established connection results in a state migration (i.e. from HTTP1 to HTTP2 or vice versa). We forgot to migrate the shutdown state. This could result in a large dealy until `.shutdown()` returns because we wait until connections are closed because of idle timeout. Worse, it could also never return if more requests are queued because the connections would not be idle and therefore not close itself.
###Changes
- Mirgrate shutdown state too
- add tests for this specific case
* simplify testMigrationFromHTTP1ToHTTP2WhileShuttingDown
* add http2 to http1 migration test
* refactor RedirectHandler
- `redirectState` is no longer a property of `HTTPClient.Request`. RedirectHandler now stores this state directly and therefore no longer optional.
- we no longer count the number of allowed redirects down. Instead the number of redirects is dervied from `self.visited.count` and we compare it to the maxRedirect to check if we git the limit.
* `HTTPClient.Configuration.RedirectConfiguration.Configuration` is now called `HTTPClient.Configuration.RedirectConfiguration.Mode`
only two `Configuration`s left in the type name
* add redirect logger test
* make `Scheme` a type
* introduce new Endpoint type
* use endpoint as storage in `HTTPClient.Request`
* fix merge conflicts
* rename Endpoint to DeconstructedURL
* swift-format
* make `DeconstructedURL` properties `var`'s
* move scheme into global namespace
- rename `useTLS` to `usesTLS` where posible without breaking public API
- only import Foundation.URL
* fix review comments
### Motivation
Our current swiftformat version does not support async/await. Since we want to add support for async/await we must update swiftformat or disable it. I tried my very best to keep the number of changes as small as possible. I assume we want to stick with the new 0.48.8 for some time.
### Changes
- Update swiftformat to 0.48.8
### Result
We can land async/await code.
### Motivation
Generally we want to inform users that they need to shutdown their HTTPClient. Until `1.6.0` we did this with an assert in HTTPClient's deinit. With `1.6.0` this behavior was raised to a precondition. Because of this adopters might suddenly crash in production where they didn't before.
### Changes
- This pr reverts the current behavior back to something pre `1.6.0`
### Result
- HTTPClient doesn't crash in production anymore.
### Motivation
Fixes#238 and #231.
### Changes
- Extracted the unclean shutdown test from `HTTPClientTests` into their own file `HTTPClientUncleanSSLConnectionShutdownTests`
- Copy and pasted @weissi great explanation from #238 into the test file
- Removed property `ignoreUncleanSSLShutdown` everywhere
### Result
`ignoreUncleanSSLShutdown` on `HTTPClient.Configuration` is deprecated and ignored.

Motivation:
In according to RFC 6265 a cookie value may be placed between double quotes.
Modifications:
HTTPClient.Cookie ignores now the double quotes at the beginning and the ending of a cookie value.
New unit test is added to check it.
Result:
Quoted cookie values are parsed properly now.
