[swift-users] Bls: Bls: module (de)-initialization
Sorry for not being clear. My english isn't very good either. What I meant was static module linking (loading and unloading) for Swift modules. Also with initialization and deinitialization for Swift modules. It's alright then. I just want to make sure. I'm a Pascal/Delphi programmer and sometimes I rely on such features in my applications. As a new and considered as modern programming language, I thought Swift would provide more advance features than Pascal/Delphi does. Thank you. –Mr Bee Pada Kamis, 22 Desember 2016 10:12, Joe Groff menulis: > On Dec 21, 2016, at 7:11 PM, Mr Bee wrote: > > > Unloading Swift modules will likely never be supported, since this would > > impose a ton of complexity and performance cost on the runtime for little > > benefit. > > Hmmm… so Swift will only support static linking?

Swift supports dynamic linking just fine; like I said, "dlopen" works. -Joe ___ swift-users mailing list swift-users@swift.org https://lists.swift.org/mailman/listinfo/swift-users

Thanks for the report! Please file it on bugs.swift.org if you have a moment.

Hmmm… so Swift will only support static linking? I thought Swift is a modern programming language with modern and advance features. Even Pascal/Delphi has had those features since ages ago. –Mr Bee Pada Kamis, 22 Desember 2016 1:06, Joe Groff via swift-users menulis: > On Dec 20, 2016, at 8:54 AM, Jens Alfke via swift-users > wrote: > > Also, AFAIK there is no mechanism in Swift (yet) to load or unload a module > at runtime, so a module load occurs when the program starts up, and an unload > occurs when the program exits. dlopen works fine, though the only supported ways of getting a callable symbol out of the loaded image are currently to use a C entry point or look up a type defined in the module by name. Unloading Swift modules will likely never be supported, since this would impose a ton of complexity and performance cost on the runtime for little benefit.

[swift-users] Swift 3 Whole Module Optimization Issue
Hi, everyone.
I think I found a swift 3 whole module optimization issue. The code
below, when building with release configuration and running on an iOS 10
real device, will always causes a crash.
import UIKit
> class ViewController: UIViewController {
> override func viewDidLoad() {
> super.viewDidLoad()
> // Do any additional setup after loading the view.
> super.viewDidLoad()
>
> let orderby = "time"

>
> Log("Request url: \(url)")

[swift-users] Using the thread sanitizer with swift test
Hello, This is my first message to the swift mailing lists, so I'd like to start with a big thank you to the Swift core team and collaborators for all the hard work. My question is related to the thread sanitizer tool. Having worked mostly with Go in recent years, I've become spoiled by the tooling and was really happy to see that swift also had a data race detector. However, where in Go I can write `go test -race` to run tests with the detector enabled, I tried `swift test -Xswiftc -sanitize=thread` but ended up with the following error: "==46839==ERROR: Interceptors are not working. This may be because ThreadSanitizer is loaded too late (e.g. via dlopen)." `swift build -Xswiftc -sanitize=thread` seems to work (i.e. it compiles without error) but since I want to test a library, that's not helpful in my case. Is that something that should be currently supported - in which case I'm missing something - or if not, is it something that is likely to be supported in the future? And then the next best thing at the moment would be to write an executable that exercises my library and build+run it with the thread sanitizer? Thanks, Martin Angers ___ swift-users mailing list swift-users@swift.org https://lists.swift.org/mailman/listinfo/swift-users
[swift-users] Question on 3 tiers architecture with Swift backend
Hi Swift Users, I want to build and apps like following architecture Tier 1 Mobile and Browser Tier 2 Swift Linux Apps (getting alot of JSON from Tier 3 and pass to Tier 1? ) Tier 3 MySQL database My question is: I have alot of SQL queries API to the database that I would like to be place in Tier 2. Currently what is the best approach to achieve this? Thanks Regards, Xing ___ swift-users mailing list swift-users@swift.org https://lists.swift.org/mailman/listinfo/swift-users
