Evented I/O streams for Swift

Compiles w/ Swift 5 snapshots.

This release adds changes to please current builds of Swift 4.2, e.g. as delivered in Xcode 10 beta 4.

There is only one major change in the API - socket structs like sockaddr_in or addr_in do not carry a custom initialiser anymore. That is a:

let a = sockaddr_in()

Is not properly initialising the address anymore, instead it just returns a 0-cleared value. Instead, use one of the other convenience initialisers we provide or make, like so:

let a = sockaddr_in.make()

This affected no user code in Noze.io itself, so you probably won't hit it either.

There was a long time bug in the routing methods (there are 3 ...) which was leaking the next closure (because that was self-referencing and in not all cases cleaning up properly).

That has been fixed and should be excellent now.

Noze.io FF adds support for Xcode 9 and Swift 4.0.

Noze.io now compiles using both, Swift 3 (3.0, 3.1 and 3.2), as well as Swift 4. The Xcode project still defaults to Swift 3 to support older Xcode installation. Note that Xcode 9 can also compile Swift 3 (known as Swift 3.2, which can be mixed w/ Swift 4).

On the SPM side Noze.io is compiled as Swift 4 when available, otherwise as Swift 3.

Two minor enhancements:

• add QS module from ExExpress
• add bodyParser.Options.extended (aka use qs instead of query_string to parse query parameters)

Added the Swiftmon/S example, a source rebuild monitor. And associated improvements to Noze.io, like in the fs.watch and child_process.spawn APIs.

Changes since 0.5.7:

• modules:
  • events:
    • bugfix in 'once' logging (drop once listeners before emitting)
  • fs:
    • watch
      • support for recursive and directory watchers
      • bugfixes
  • child_process:
    • API changes to kill (default value, return value, etc)
• samples:
  • Swiftmon/S - a source rebuild monitor
• Add TCP_NODELAY option for sockets
• Xcode 9 upgrade checks
• Swift 3.2
  • drop @_specialize in CryptoSwift fork
  • stat hack (stat uses lstat)
  • types use .self
  • no more (Void)->Void
  • redundant conformance
  • args after varargs need a name
• Swift 3.1 compile fixes

Annoyed that your TCP packets always arrive in an orderly fashion? Want to bring more risk to your socket communication? Noze.io has you covered.

Release 0.5.7 adds the new dgram module contributed by @lichtblau. Example UDP echo daemon:

sock = dgram.createSocket()
sock
  .onMessage   { (msg, from) in
    sock.send(msg, to: from) // echo back
  }
  .bind(1337)

Also: fixes for new warnings emitted by Swift 3.1, also contributed by @lichtblau.

Small bugfix / upgrade release:

• Fixed a bug that happened when the middleware stack was empty.
• Use Swift 3.0.2 in Travis (Xcode 8.2 on macOS)
• Allow MiddlewareObjects to be directly used in app.get() etc.

Tiny bugfix release. A thing is that the default listen queue size got bumped from 5 to 512.

• fix source width to be max 80 columns
• bump listen backlog to 512
• typos
• fix makefile build
• a few more docs
• drop some Swift 2 legacy
• make process.platform public

Minor bugfix release.

streams module:

• Bugfix: Fix piping of empty Readable's. When a callback based Readable w/o an actual callback (manual push) got piped, it was issuing an EOF push. This would close the pipe. Instead just ignore the read request and wait for the user to push something to the Readable (content or EOF).

net module:

• fix bug in capturing errno

tests:

• fix setup&compilation of Linux tests
• fix Freddy tests for Swift 3.0
• new pipe tests for callback based streams

• crasher in end handler
• some API cleanup

Small release which adds some basic-auth support, a bug fix for readable streams and some Swift error support for the builtin promises.

• use Linux 3.0.1 GMc which fixes SE-2907
• Add support for throws in promises, directly throw errors in promise callbacks.
• streams/ReadableStream: emit a nil-onRead before emitting endReadable
• simple basic-auth module

Noze.io 0.3.1 is a minor release which just adds two things: a) compatibility with Swift 3 Preview 4 on both macOS & tuxOS and b) use of the new protocol based http_parser port.

• global changes
  • compat with Swift 3 Preview 4 on tuxOS & macOS
    • ErrorProtocol is now Error (2.x alias provided in core)
    • UnsafePointer changes
    • xyzLiteralConvertible is now ExpressibleByXYZLiteral (2.x alias provided in core)
    • enum cases must be accessed via .
    • operator funcs are static
    • a few more Objective-GCD changes
    • new POSIXErrorCode vs POSIXError
• http_parser module
  • switched from closure based http_parser to a protocol based http_parser (faster, more consistent with original)
• http module
  • use protocol based http_parser
• tests
  • renamed to match what Swift 3 Preview 6 is expecting (still works with older versions)

Noze.io is getting persistent. The feature of this release is the new Redis client. Includes a todo-list backend example which stores the todos into Redis.

Also featuring:

• convert stuff to be more Swift 3 like while maintaining Swift 2 compat
• Swift 3 Preview 2 adjustments
• a common protocol for Unix time value structures (time_t, timeval_t, timespec_t)
• connect.pause middleware
• bug fixes. and more bug fixes.

Fixed Noze.io build on macOS with the Swift 3 Preview 1 included in Xcode 8beta aka Objective-GCD.

Bugfixes and lots of cows!

Added very simple cookie and session middleware. Fixed some bugz.

Hotfix, just fixes a crasher in GCD channel implementation.
