Motivation:
NIOTS will not work on Linux but we can at least make it not fail
compilation when compiled on Linux. That way consumers of the API can
depend on NIOTS but make sure they only use NIOTS when wrapped in a
`#if canImport(Network)` block.
Modification:
Guard everything by `#if canImport(Network)`
Result:
This package will now build on Linux (without providing any useful
code).
Motivation:
Once every few thousand years, an event called syzygy (or "convergence")
occurs in our solar system. When these events occur, the fabric of spacetime
becomes thin, allowing reflections of a possible future to appear in our
reality.
This gives a few brave souls the opportunity to experience a future: a
possibility of the way the universe may one day be. But be warned: to
toy with causality is to risk unbearable pain and suffering. Only the
bravest of souls should look too closely at these shadows of the future.
Modifications:
- Chose a firm anchor point in the SwiftNIO timeline.
- Removed the braces that kept time travellers safe.
- Said a quiet prayer.
Result:
Opportunity.
Motivation:
Some users may wish to use peer-to-peer networking with bonjour.
Modifications:
Expose peer-to-peer networking via a new channel option.
Result:
Users will be able to use peer-to-peer networking
(cherry picked from commit e9c1e41fd1)
Motivation:
Compiling code is good so let's make it compile again with the latest
NIO APIs.
Modifications:
- made NIOTS use `_NIO1APIShims`
- clicked 'Fix All' a couple of times to adjust the API
Result:
Code compiles again
Motivation:
SwiftPM from Swift 5.0 brings targets that only support certain systems
which is really handy for this package as it only support macOS 10.14+
and iOS/tvOS 12+
Modifications:
- made use of the Swift 5.0 manifests which can have restrictions on the
supported platforms
- adapted to NIO 2
Result:
- better development story
- using the latest & greatest
Motivation:
In some cases, such as when an event loop has been shutdown, channel
registration may fail. In these cases, we would incorrectly attempt to
deregister the channel, which would fail (and in debug builds, assert).
Really, we shouldn't transition into .registered until we know that we have,
in fact, registered.
However, we need to be cautious: we don't want to register unless we
believe we're in an acceptable state to register.
Modifications:
Updated the state enum to perform the registration at the correct
part of the state change function.
Result:
Harder to crash in debug mode
Motivation:
Sadly I overlooked the fact that Channel.isActive is supposed to be
safe to call from multiple threads: the implementation here was not.
Modifications:
Store the active state into an Atomic.
Result:
It will be thread-safe to ask if a channel is active.
Motivation:
In some cases users may prefer not to wait for Network.framework to
reattempt connection in the future. Users should be able to opt-out of the
default waiting behaviour in those cases.
Modifications:
- Added WaitForActivity ChannelOption.
Result:
Users can configure channels better.
Motivation:
If an error is encountered early in the bootstrap process we should
probably not hit an assertion.
Modifications:
Added tests that we don't crash when closing idle channels.
Result:
Fewer crashes.
Motivation:
These are commonly-set socket options for channels, and we should
support them when using Transport Services as well.
Modifications:
Pass the socket options through to allowLocalEndpointReuse.
Result:
SO_REUSEADDR and SO_REUSEPORT will be available.
