CL 294430 made packages in std and cmd modules use Go 1.17 gofmt format, adding //go:build lines. This change applies the same formatting to some more packages that 'go fmt' missed (e.g., syscall/js, runtime/msan), and everything else that is easy and safe to modify in bulk. Consider the top-level test directory, testdata, and vendor directories out of scope, since there are many files that don't follow strict gofmt formatting, often for intentional and legitimate reasons (testing gofmt itself, invalid Go programs that shouldn't crash the compiler, etc.). That makes it easy and safe to gofmt -w the .go files that are found with gofmt -l with aforementioned directories filtered out: $ gofmt -l . 2>/dev/null | \ grep -v '^test/' | \ grep -v '/testdata/' | \ grep -v '/vendor/' | wc -l 51 None of the 51 files are generated. After this change, the same command prints 0. For #41184.

Go on iOS ========= To run the standard library tests, run all.bash as usual, but with the compiler set to the clang wrapper that invokes clang for iOS. For example, this command runs all.bash on the iOS emulator: GOOS=ios GOARCH=amd64 CGO_ENABLED=1 CC_FOR_TARGET=$(pwd)/../misc/ios/clangwrap.sh ./all.bash If CC_FOR_TARGET is not set when the toolchain is built (make.bash or all.bash), CC can be set on the command line. For example, GOOS=ios GOARCH=amd64 CGO_ENABLED=1 CC=$(go env GOROOT)/misc/ios/clangwrap.sh go build Setting CC is not necessary if the toolchain is built with CC_FOR_TARGET set. To use the go tool to run individual programs and tests, put $GOROOT/bin into PATH to ensure the go_ios_$GOARCH_exec wrapper is found. For example, to run the archive/tar tests: export PATH=$GOROOT/bin:$PATH GOOS=ios GOARCH=amd64 CGO_ENABLED=1 go test archive/tar The go_ios_exec wrapper uses GOARCH to select the emulator (amd64) or the device (arm64). However, further setup is required to run tests or programs directly on a device. First make sure you have a valid developer certificate and have setup your device properly to run apps signed by your developer certificate. Then install the libimobiledevice and ideviceinstaller tools from https://www.libimobiledevice.org/. Use the HEAD versions from source; the stable versions have bugs that prevents the Go exec wrapper to install and run apps. Second, the Go exec wrapper must be told the developer account signing identity, the team id and a provisioned bundle id to use. They're specified with the environment variables GOIOS_DEV_ID, GOIOS_TEAM_ID and GOIOS_APP_ID. The detect.go program in this directory will attempt to auto-detect suitable values. Run it as go run detect.go which will output something similar to export GOIOS_DEV_ID="iPhone Developer: xxx@yyy.zzz (XXXXXXXX)" export GOIOS_APP_ID=YYYYYYYY.some.bundle.id export GOIOS_TEAM_ID=ZZZZZZZZ If you have multiple devices connected, specify the device UDID with the GOIOS_DEVICE_ID variable. Use `idevice_id -l` to list all available UDIDs. Then, setting GOARCH to arm64 will select the device: GOOS=ios GOARCH=arm64 CGO_ENABLED=1 CC_FOR_TARGET=$(pwd)/../misc/ios/clangwrap.sh ./all.bash Note that the go_darwin_$GOARCH_exec wrapper uninstalls any existing app identified by the bundle id before installing a new app. If the uninstalled app is the last app by the developer identity, the device might also remove the permission to run apps from that developer, and the exec wrapper will fail to install the new app. To avoid that, install another app with the same developer identity but with a different bundle id. That way, the permission to install apps is held on to while the primary app is uninstalled.
