Unity 2018.3 brings us even more thread-safe APIs that we can call from the C# job system. Today we’ll look at a systematic way to find them all so we know what’s safe to use and what’s not.

Update: A Russian translation of this article is available.

Previous articles (2018.1, 2018.2) have featured lists of job-safe APIs, but those lists were generated with a combination of decompiling all of Unity’s DLLs, using grep to find [ThreadSafe] and IsThreadSafe = true, then manually formatting the results for the article. It’s a lengthy, tedious, and error-prone process that can be improved.

So for today, we now have a little Unity editor script that will generate the list for us. Here’s what it does:

Find all the .dll files in the Unity install directory’s Managed sub-directory
Open them as an Assembly
Scan through all their methods and properties
Check if the [NativeMethod] attribute is present
Call the get for NativeMethodAttribute.IsThreadSafe
Output all the matches to Debug.Log and the system clipboard

The following script runs on macOS only right now, but can be easily modified to support Windows or Linux if necessary by changing managedDirPath:

using System;
using System.Collections.Generic;
using System.IO;
using System.Reflection;
using System.Text;
using UnityEngine;
using UnityEditor;
 
public static class JobSafeMenuItem
{
    [MenuItem("Help/List Job Safe APIs")]
    private static void JobSafe()
    {
#if !UNITY_EDITOR_OSX
        throw new Exception("Only macOS is supported at this time");
#endif
        string managedDirPath = Path.Combine(
            Path.Combine(
                EditorApplication.applicationPath,
                "Contents"),
            "Managed");
        Type nativeMethodAttribute = Assembly.LoadFile(
            Path.Combine(
                Path.Combine(
                    managedDirPath,
                    "UnityEngine"),
                "UnityEngine.SharedInternalsModule.dll"))
            .GetType("UnityEngine.Bindings.NativeMethodAttribute");
        string[] paths = Directory.GetFiles(
            managedDirPath,
            "*.dll",
            SearchOption.AllDirectories);
        var methodsByType = new Dictionary<Type, List<string>>(512);
        object[] emptyParameters = { };
        void AddIfThreadSafe(Type type, Attribute attribute, string method)
        {
            if (nativeMethodAttribute.IsInstanceOfType(attribute)
                && (bool)nativeMethodAttribute
                    .GetProperty("IsThreadSafe")
                    .GetGetMethod()
                    .Invoke(attribute, emptyParameters))
            {
                List<string> list;
                if (!methodsByType.TryGetValue(type, out list))
                {
                    list = new List<string>(32);
                    methodsByType[type] = list;
                }
                list.Add(method);
            }
        }
        BindingFlags allFlags =
            BindingFlags.NonPublic
            | BindingFlags.Static
            | BindingFlags.Instance;
        foreach (var path in paths)
        {
            Assembly assembly = Assembly.LoadFile(path);
            foreach (Type type in assembly.GetTypes())
            {
                foreach (MethodInfo meth in type.GetMethods(allFlags))
                {
                    foreach (Attribute attribute in meth.GetCustomAttributes())
                    {
                        AddIfThreadSafe(type, attribute, meth.ToString());
                    }
                }
                foreach (PropertyInfo prop in type.GetProperties(allFlags))
                {
                    foreach (Attribute attribute in prop.GetCustomAttributes())
                    {
                        AddIfThreadSafe(type, attribute, prop.ToString());
                    }
                }
            }
        }
 
        StringBuilder builder = new StringBuilder(1024 * 10);
        var sortedMethodsByType = new List<KeyValuePair<Type, List<string>>>(
            methodsByType);
        sortedMethodsByType.Sort((a, b) => a.Key.Name.CompareTo(b.Key.Name));
        foreach (var pair in sortedMethodsByType)
        {
            pair.Value.Sort();
            foreach (string method in pair.Value)
            {
                builder.Append(pair.Key.Name);
                builder.Append(":    ");
                builder.AppendLine(method);
            }
        }
        Debug.Log(builder.ToString());
        EditorGUIUtility.systemCopyBuffer = builder.ToString();
    }
}

To use it, just paste into a .cs file in an Editor folder in a Unity project. Then click Help > List Job Safe APIs to run the script. It takes a few seconds and then shows a log in the Console pane. The log is quite long and likely to be truncated, but it’s also been copied to the system clipboard. Paste it into a text editor to see the full results.

We’re now up to 301 job-safe APIs, but many of them are private or internal to Unity and so must be called indirectly via a public API. All in all, it’s just an expansion of nine methods and properties since Unity 2018.2. However, Unity increasingly relies on packages to provide new functionality such as the ECS currently in Preview. To inspect any other libraries with this script, simply change the paths variable to include their directories.

Dear Jackson,
after years standing like a last Japanese on a pacific island, I feel it’s time to move away from AS3 (yes, I managed to make a living with AIR so far). I am considering a transition to Unity in order to retain a similar freedom as in the Flash platform.
How does it feel working in Unity after many yars of beautiful AS3? And how is it professionally? I have been a freelance all my life and want to stay a freelance, but I see there are many more jobs and gigs in the hated JS world than in Unity. Might I ask your views on these isues?
Thank you very much
Pino

Hi Pino,

I responded to your comment via e-mail since it’s off-topic for this article.

I tried porting this to Windows and found that maybe this would work on all OS.
Can someone confirm it?
