SwiftWasm 5.9 release

[kateinoigakukun]

TODO:

• Repair CI Repair main and release/5.9 build swiftwasm-build#99
• Prepare Swift SDK artifactbundle
• [Postponed] Implement some critical build system features
  • Experimental Swift SDK integration
  • SwiftPM Build Plugin support (Supported in 5.9.2)
• Check core libraries and tools are compatible with the toolchain
  • JavaScriptKit Swift 5.9 Changes JavaScriptKit#229
  • carton Add 5.9 support carton#412
  • Tokamak: Manually tested with wasm-5.9-SNAPSHOT-2024-01-12-a
• Set 5.9.1 as default value of swift-compiler-version build-script option
  • This step will be unnecessary from the next release, because we can use upstream pre-built toolchain.
• Dispatch distribution workflow

gh workflow run manual-distribution.yml -f run-id=$RC_RUN_ID -f scheme=release-5.9 -f override-name=swift-wasm-5.9.1-RELEASE -f display-name="Swift for WebAssembly 5.9.1 Release $(date +'%Y-%m-%d')" -f display-name-short="Swift for WebAssembly 5.9.1 Release" -R swiftwasm/swift

(Replace $RC_RUN_ID with the GitHub Actions run id for the release candidate build)

After tagging the toolchain version

• Release a new version of JavaScriptKit https://github.com/swiftwasm/JavaScriptKit/releases/tag/0.19.0
• Release a new version of carton https://github.com/swiftwasm/carton/releases/tag/0.20.0
• Push a new version of switwasm-docker
• Push a new version of swiftwasm-action
• Update the setup guide in https://github.com/swiftwasm/swiftwasm-book/blob/main/src/getting-started/setup.md
• Announcement blog post https://blog.swiftwasm.org/posts/5-9-released/

Current blockers

Please report any other issues found in the latest release snapshots to help us prioritize them.

Rebuilding toolchain since the arm64-darwin toolchain in the release candidate contained unexpected linkage reference to libzstd installed via homebrew. The build job is running at https://github.com/swiftwasm/swiftwasm-build/actions/runs/7532149900/job/20502246203

SwiftWasm 5.9.1 released! https://blog.swiftwasm.org/posts/5-9-released

See https://book.swiftwasm.org/getting-started/setup.html for each download link

We started distributing Swift SDK artifactbundles: swiftwasm/swiftwasm-build#180

You can install WebAssembly SDK by following commands with Swift 5.9 installed:

$ swift experimental-sdk install https://github.com/swiftwasm/swift/releases/download/swift-wasm-DEVELOPMENT-SNAPSHOT-2024-01-26-a/swift-wasm-DEVELOPMENT-SNAPSHOT-2024-01-26-a-ubuntu20.04_x86_64.artifactbundle.zip
$ swift package init --type executable --name Example
$ swift build --experimental-swift-sdk wasm32-unknown-wasi
$ wasmtime .build/debug/Example.wasm

The initial artifact release is a little bit fat, but swiftlang/swift-sdk-generator#80 will mitigate it.

Thank you for sharing the information.

For installing from GitHub, the --checksum option is required. However, I didn't find checksums because GitHub doesn't show them on the download page.

$ swift experimental-sdk install https://github.com/swiftwasm/swift/releases/download/swift-wasm-DEVELOPMENT-SNAPSHOT-2024-01-26-a/swift-wasm-DEVELOPMENT-SNAPSHOT-2024-01-26-a-ubuntu20.04_x86_64.artifactbundle.zip
Error: downloadError("Error Domain=NSURLErrorDomain Code=-1001 \"(null)\"")

So I had to download it once and then install it.

$ curl -LO https://github.com/swiftwasm/swift/releases/download/swift-wasm-DEVELOPMENT-SNAPSHOT-2024-01-26-a/swift-wasm-DEVELOPMENT-SNAPSHOT-2024-01-26-a-ubuntu20.04_x86_64.artifactbundle.zip
$ swift experimental-sdk install swift-wasm-DEVELOPMENT-SNAPSHOT-2024-01-26-a-ubuntu20.04_x86_64.artifactbundle.zip
swift-wasm-DEVELOPMENT-SNAPSHOT-2024-01-26-a-ubuntu20.04_x86_64.artifactbundle.zip is assumed to be an archive, unpacking...
Swift SDK bundle at `swift-wasm-DEVELOPMENT-SNAPSHOT-2024-01-26-a-ubuntu20.04_x86_64.artifactbundle.zip` successfully installed.

@KKK669 Which host swift version are you using?

[kkebo]

@kateinoigakukun I'm using Swift 5.9.2 on Linux aarch64, so I actually installed https://github.com/swiftwasm/swift/releases/download/swift-wasm-5.9-SNAPSHOT-2024-01-28-a/swift-wasm-5.9-SNAPSHOT-2024-01-28-a-ubuntu20.04_aarch64.artifactbundle.zip. Also, I tried Swift main snapshot.

The requirement of --checksum is not host-dependent. According to the Swift Evolution proposal, it's generally required.

For Swift SDKs installed from remote URLs an additional --checksum option is required, through which users of a Swift SDK can specify a checksum provided by a publisher of the SDK.

[kateinoigakukun]

@KKK669 Actually the checksum verification feature is not even implemented yet in SwiftPM. So I suspect there should be a different problem here. Would you mind trying it again after uninstalling the SDK. I guess there might be internet connection issue?

[kkebo]

@kateinoigakukun I see. Sorry for my misleading information.

[kkebo]

I guess there might be internet connection issue?

By the way, it turned out that downloadError("Error Domain=NSURLErrorDomain Code=-1001 \"(null)\"") was caused by swiftly. It was a symbolic link issue as well as this one. And it also seems to happen when downloading an artifact bundle.
