Alamofire: Add server / linux support once Swift 3 is released

[vherrin]

There is a need to run Alamofire on Open Swift server platforms

We're certainly very interested in this possibility! Once we get closer to seeing exactly how the linux Foundation is implemented, we'll start investigating how we'll need to modify Alamofire to support it.

Cheers. 🍻

Development of Swift 3 is almost finished and dispatch/NSURLSession will be supported on Linux. It would be great to start considering working on the possibility to port Alamofire to Linux.

Any news on the development of the above function?

[vherrin]

agree any news?

I subclassed the swift 3 docker container and added a sshd daemon / zsh

As the trend of backend development is to go microservices - swift will likely find it's niche / foothold there.

UPDATE - so after some faffing around - running with above swift3 ubuntu docker container and patching Package.swift to 4.0.2 tag ->

I get ....
/tmp/SPMTester/Packages/Alamofire-4.0.2/Source/NetworkReachabilityManager.swift:28:8: error: no such module 'SystemConfiguration'

One shot script to download + patch alamofire run from inside docker container...
eg.

wget https://gist.githubusercontent.com/johndpope/e590169f7a0aaf08e52ba25a75bcd8d1/raw/5f1a3743e61224f7ae7963d4c61d79a5233c531f/cloneAlamofire.sh
chmod +x cloneAlamofire.sh

with my docker container + ssh - you can then simply configure cyberduck to edit files in container. N.B. rather than version bumping package each time to test - you can fork and update script above to point your own files - blow away stuff and recompile.

I added code to bypass systemconfiguration

but looks like there's wider troubles now
error: use of undeclared type 'NetService'
error: use of undeclared type 'DispatchQueue'

still digging...

tried adding import Dispatch - but no joy.

As an alternative - probably safest to go with vapor

This Edge framework seems like another nice alternative to alamofire for server side swift https://github.com/SwiftOnEdge/Edge

so this looks blocked until Apple implement NSURLSession - shared

One path forward could be to use libcurl -
IBM has libcurl c wrapper in swift for linux - and someone recently made a swifty wrapper for this.

Suggestion: we should move this discussion to #1935

[jshier]

Yes, all Linux discussion is now in #1935.
