On macOS in JIT mode, missing `com.apple.security.cs.allow-jit` entitlement crashes with confusing `Exhausted heap space, trying to allocate 32 bytes` error #50719

Closed jmagman closed 1 year ago

jmagman commented 1 year ago

On macOS in JIT mode, when the com.apple.security.cs.allow-jit entitlement is missing, the app crashes on launch with the error Exhausted heap space, trying to allocate 32 bytes.... error: Out of memory..

It would be far better if the crash was instead actionable and informed the developer that they should add that entitlement.

Reported in https://github.com/flutter/flutter/issues/115916, @dubik was testing out macOS add-to-app, so Flutter wasn't able to generate the Debug entitlement file.

Steps to Reproduce (check WeatherApp.zip)

  1. Create flutter application flutter create --template app --platforms macos weather_app
  2. cd weather_app
  3. flutter build macos-framework

Create macOS application using XCode (Swift and storyboard is fine).

  1. Find App.xcframework and FlutterMacOS.xcframework inside weather_app/build/macos/frameworks/Debug, drop them to project settings like so:

  1. Replace AppDelegate.swift with this:
import Cocoa
import FlutterMacOS

@main
class AppDelegate: NSObject, NSApplicationDelegate {
    var engine: FlutterEngine?;

    func applicationDidFinishLaunching(_ aNotification: Notification) {
        engine = FlutterEngine.init(name: "Weather", project: nil, allowHeadlessExecution: true)
        engine?.run(withEntrypoint: nil); // <<<--- this is where it crashes

        var channel = FlutterMethodChannel(name: "mychannel", binaryMessenger: engine!.binaryMessenger)
        channel.invokeMethod("makeString", arguments: 123)
    }

    func applicationWillTerminate(_ aNotification: Notification) {
        // Insert code here to tear down your application
    }

    func applicationSupportsSecureRestorableState(_ app: NSApplication) -> Bool {
        return true
    }
}

@rmacnak-google what does the error look like now when the entitlement is missing?
