Subject: Virtual threads created more platform threads
Message-ID: <CAAMX02oVCSxnkJ0NqdZni1mk6jz7-vVKZ6B32+6SJmS8XSNY6A@mail.gmail.com>

Hi Loom-dev Community,

I have a question about platform thread creation triggered by calling
future.get() within virtual threads, and I would like to ask the community
for assistance. The detailed information can be found in this issue:
https://github.com/adoptium/adoptium-support/issues/1319. I hope to receive
some help from the community regarding this matter. Thank you.
Additionally, I'd like to know if this situation will still occur in JDK 24
and above?

Best Regards.

Future.get() should not create additional platforms threads. I suspect it is something else. I would start by providing a simple test case using futures only and you shouldn?t see them increase.

Hello, I don't think this would happen for JDK 24 - JEP 491 removed the
code that calls Blocker in Object.wait, which is exactly the goal of that
JEP.

Note that virtual threads are still pinned when call stack goes into
native, as native execution may pass address to stack variables that will
be lost in context switches. In these cases, the traditional managed block
happens again.

P.S. I personally think it is somewhat not responsible for JDK vendors to
ask users to upstream a question for an older JDK release that might no
longer apply on the latest release to a development-oriented mailing list.

I hope to not create noise with my own comments, and I will concur with you
that JEP 491 should mean this is resolved in Java 24, which Jianbin Chen
should try out before and then alongside Robert's recommendation for
creating a very simple reproduction.

As Java 21 is still the current LTS, it isn't completely unreasonable to
forward concerns to the mailing list. My understanding in this particular
case is that JEP 491 is not going to be back ported to Java 21 as it has a
dependency from a change in Java 23. (Potentially more, I can't remember
the conversation completely, I only skimmed that email chain)


Thanks,
- Peter

P.S. As I do a similar job, I'd like to call out that Vendors letting the
occasional support question slip into here is a fine price to pay for the
amount of questions they handle instead.

Hi everyone,
thank you for your replies and assistance. So this issue occurring in JDK
21 is considered normal behavior, correct? However, I've observed that
these expanded threads are not being garbage collected - they remain in a
waiting state for several minutes without disappearing. Sometimes they can
expand to several hundred threads, and these threads, once created, remain
unused, continuously wasting thread resources. Therefore, I'm attaching a
local reproduction example of this issue to ensure the information in this
email is complete.
-Djava.util.concurrent.ForkJoinPool.common.parallelism=1
`
The following example clearly shows the forkjoinpool expanding. I have also
recorded the runtime stack trace for this and submitted it as an attachment.

```
    public static void main(String[] args) throws InterruptedException {
        Executor executor =
ThreadPoolFactory.newVirtualThreadPerTaskExecutor();
        String a = "a";
        executor.execute(() -> {
            synchronized (a) {
            try {
            a.wait();
            } catch (InterruptedException e) {
            throw new RuntimeException(e);
            }
            }
        });
        executor.execute(() -> {
            synchronized (a) {
            try {
            a.wait();
            } catch (InterruptedException e) {
            throw new RuntimeException(e);
            }
            }
        });
        Thread.sleep(120000);
    }
```
After switching to using condition, it can be clearly observed through
jstack that the forkjoinpool did not expand as many threads, but 3 threads
still appeared, which might be related to incorrect usage of my JVM
parameters.

```
 public static void main(String[] args) throws InterruptedException {
        Executor executor =
ThreadPoolFactory.newVirtualThreadPerTaskExecutor();
        List<ReentrantLock> list = new ArrayList<>();
        list.add(new ReentrantLock());
        list.add(new ReentrantLock());
        list.add(new ReentrantLock());
        list.add(new ReentrantLock());
        list.add(new ReentrantLock());
        list.add(new ReentrantLock());
        for (int i = 0; i < list.size(); i++) {
            ReentrantLock value = list.get(i);
       Condition condition = value.newCondition();
            executor.execute(() -> {
                value.lock();
                    try {
                        condition.await();
                    } catch (InterruptedException e) {
                        throw new RuntimeException(e);
                    }finally {
                        value.unlock();
                    }
            });
        }
        Thread.sleep(120000);
    }
```

Hello Peter,
I find multiple misunderstandings in your response. Let me clarify these.

About the process: Jianbin is using a specific product maintained by a
vendor for an older JDK release. The vendor should ask the Jianbin to try
on the latest JDK release before asking to forwarding this to loom. We
cannot expect general users to understand the order of steps to take here.

About backporting: JEP 14, the tip and tail release model, explicitly rules
out the tail releases from addition of performance improvements; JEP 491 is
clearly not crucial to the security of older releases and should not be
backported.

About LTS releases: they are not associated with the active development of
JDK, as evident on jdk.java.net. Any vendor can declare any release
supported; they must at least provide quarterly updates with all security
fixes. For openjdk, all past releases that are supported in open source are
discussed on the jdk-updates-dev list. Oracle offers premium support (not
part of openjdk) for their chosen releases called LTS releases, and
openjdk's jdk updates project decides to support the same releases. The
argument that active jdk development is responsible for maintenance of a
particular supported release, including ones considered LTS, does not stand.

24. 21 is not supported by active JDK development.

Hi Liang,

Thank you and everyone for your patient answers. I verified this with JDK
24, and the same example did not show platform thread growth. However,
there's one thing I don't understand: why are these threads never
reclaimed? Most of them are in a waiting state - isn't this a waste of
resources? Sometimes it increases by hundreds of threads. Is there any way
to suppress this behavior on JDK 21?

Best Regards.

Just to confirm what was already said. The stack trace in the issue 
shows Netty DefaultPromise.await in Object.wait. Prior to JDK 24 this 
pinned the carrier thread. The implementation (prior to JDK 24) attempts 
to compensate for this by arranging for a spare platform thread (FJP 
worker) to be available. This seems to be what you are seeing. The 
number of threads won't grow to more than 256. The "Implementation Note" 
section of the Thread class description documents the system property to 
change this limit if necessary. It's very possible that setting it to a 
number will cause the system to hang/deadlock as no virtual thread can 
make progress if they are all blocked in Object.wait and waiting for 
another virtual thread to notify.

As regards trimming. The idle workers will terminate once a keep alive 
time (30s, not configurable) is reached but only if the system is idle 
(at quiescent in FJP speak). In a busy system, or even a tiny load such 
as heart beat, then it may not happen. There were improvements in JDK 22 
[1] but it still requires that the system be idle for threads to terminate.

Hi Alan,

Thank you for your detailed explanation, but I still have some questions.

I added these parameters to limit platform threads:
-Djava.util.concurrent.ForkJoinPool.common.parallelism=2
-Djdk.virtualThreadScheduler.parallelism=2
-Djdk.virtualThreadScheduler.maxPoolSize=2
-Djava.util.concurrent.ForkJoinPool.common.maximumSpares=2.

Initially, I only added `jdk.virtualThreadScheduler.maxPoolSize=2`, but I
found it had no effect. I then thought this parameter only limits the
number of platform threads for normal virtual threads and doesn't cover
cases with pinned threads. So I added the
java.util.concurrent.ForkJoinPool.common.maximumSpares parameter again, but
it still had no effect - the threads keep growing. My JDK version is
Temurin OpenJDK 21.0.7+6. I've also attached the jstack stack trace
information.

Best Regards.

Are you 100% sure that you specify the -D as a VM option rather than a 
program argument?

I'm sorry, I was running the main method directly in IDEA. I tried to add
the parameters through 'add vm options' in 'edit configuration', but I
selected the wrong option - I chose 'program arguments' so the parameters
didn't take effect. Now I have successfully limited the maximum number of
platform threads through jdk.virtualThreadScheduler.maxPoolSize. Thank you
very much for everyone's help and answers!

Best Regards.

Right, and as a reminder: the changes were to the lightweight locking 
mode only (not legacy) and that mode only became the default in JDK 22. 
There is also a prerequisite spec change to JVMTI GetObjectMonitorUsage 
that happened in JDK 23. It also seems pointless given that JDK 24 is 
already released and JDK 25 is very close.

Sorry to bother you all again. When using virtual threads on JDK 21, I've
always been concerned about potential pinning situations, so during testing
in our offline environment, we always add the -Djdk.tracePinnedThreads=full
parameter. However, we have never seen any pinned-related information
output. Yesterday I conducted a test and found that when using synchronized
+ object.wait(), even though the maximum number of platform threads used by
virtual threads has already reached the limit, it still cannot output
pinned-related logs. But if I switch to synchronized + Thread.sleep(), it
can output the logs. I'm providing my example and JVM parameters below,
hoping someone can help explain this issue. Thank you very much.

JVM parameters: -Djdk.tracePinnedThreads=full
-Djava.util.concurrent.ForkJoinPool.common.parallelism=2
-Djdk.virtualThreadScheduler.parallelism=2
-Djava.util.concurrent.ForkJoinPool.common.maximumSpares=2
-Djdk.virtualThreadScheduler.maxPoolSize=2

```
public static void main(String[] args) throws InterruptedException {
    Executor executor = ThreadPoolFactory.newVirtualThreadPerTaskExecutor();
    List<String> list = new ArrayList<>();
    for (int i = 0; i < 20; i++) {
        list.add(String.valueOf(i));
    }
    for (int i = 0; i < list.size(); i++) {
        String value = list.get(i);
        executor.execute(() -> {
            synchronized (value) {
                try {
                    value.wait();
                } catch (InterruptedException e) {
                    throw new RuntimeException(e);
                }
            }
        });
    }
    Thread.sleep(120000);
}
```

Hello everyone

Has anyone taken a look at my example? I'm really curious to know why JDK
21 cannot detect pinned platform thread behavior in this particular
example. If someone could help explain this, I would be extremely grateful!

Best Regards.

That rudimentary tracing/debug option printed a stack trace when a 
virtual thread parked inside a synchronized method. It didn't help with 
Object.wait or other cases.

Once you get to JDK 24+ you can drop -Djdk.tracePinnedThreads=full as 
this system property has no effect. The changes to object monitors in 
JDK 24, and the improvements to JFR events for pinning in the same 
release, means the tracing option isn't needed.

Subject: Custom scheduler: Using loom for deterministic simulation testing
Message-ID: <CAO4jUyUObxU=NuMLabfEHt2MSBiWzjWEfncg0YKQNsukoKUgjg@mail.gmail.com>

Hi,
I have also been looking into deterministic simulation on the side and
belatedly saw some interest about it on the loom email list with the
"Custom scheduler: Customize current time and timed waits" thread. I wanted
to briefly expand on the topic of using Loom to make deterministic
simulation testing more easily available to the java community.

BLUF:  Deterministic simulation testing makes multi threaded logic single
threaded and fuzz tests the execution order, greatly simplifying discovery
of race conditions and deadlocks. See this blog post by Ao Li
<https://aoli.al/blogs/jdk-bug/> for an example doing this in java and the
paper behind it  Fray: An Efficient General-Purpose Concurrency Testing
Platform for the JVM <https://arxiv.org/abs/2501.12618>.

The above explanation omits how hard it is to actually make java or any
language deterministic. This is where James Baker had a clever idea
<https://jbaker.io/2022/05/09/project-loom-for-distributed-systems/> of
using Loom, since we could replace the virtual thread scheduler with a
deterministic one, Loom does most of the work for us without any extra
frameworks. This works brilliantly, however there are three main caveats:

   1. Its not easy to replace the virtual thread scheduler
   2. The aforementioned scheduler has no understanding of delays so any
   Thread.sleep or Object.wait introduces continuations back into the
   scheduled execution pool non-deterministically. This affects the execution
   order so bugs can't always be reproduced.
   3. IO also introduces continuations back to the scheduler execution pool
   non-deterministically.

The first issue can currently be solved by using reflection to make the virtual
thread constructor public
<https://github.com/ryeats/loom-dst/blob/main/src/main/java/org/example/SchedulableVirtualThreadFactory.java>.
The
second issue can currently be solved by controlling system time by
replacing the byte code for all calls to System.nanoTime(),
System.onCurrentTimeMillis() and Instant.now() using an agent at runtime
<https://github.com/cmu-pasta/fray/blob/main/instrumentation/base/src/main/kotlin/org/pastalab/fray/instrumentation/base/visitors/TimeInstrumenter.kt>.
The third likely has no general solution but I am interested in hearing
ideas.

Even if there is no solution to IO non-determinism and developers have to
stub out all IO, deterministic simulation is still an incredibly promising
tool for making concurrent and distributed systems programing much simpler
and safer. I think because of this use case there would be a lot of benefit
if the Loom API allowed instrumenting the scheduler, even better if we
could access the DELAYED_TASK_SCHEDULERS which understand delays.

Thank you for your time, I have been super excited to use virtual threads
and amazed by the ingenuity that brought them to java.

Ryan

There are experimental changes in the loom repo to allow the virtual 
thread scheduler be replaced or wrapped. There is also a prototype API 
to set a scheduler when creating a virtual Thread. There is a doc in the 
repo with more on this [1]. This project hasn't decided whether to 
expose anything so any reports from experiments would be useful to hear 
about.

Ryan, what I'd suggest is just clicking fork on GitHub and making a JDK spin with the changes needed. If you've never done it before, building a fork of the JDK is much easier than you'd expect. It's an easy codebase to work on, especially if the only changes you need are in the Java side. Then you can just directly alter the visibility of the various things needed, figure out what a good API looks like and submit a PR. Even if it's never merged, it would significantly refine the discussion around what's required.

For example, rather than patching the different time APIs with an agent it might make sense to load an InstantSource using an SPI and modify the implementations to route all time queries to that. A lot of software is sensitive to how fast System.nanoTime or currentTimeMillis executes, so that needs a bit of thought (maybe the compiler can be forced to always inline through the default implementation if no SPI is in use).

For deterministic IO, I don't think you want to operate at the level of sockets or file handles. That's too low level to make sense to developers in most cases. If you want to control when a reply comes back in from a database it'd be better to just use the DI framework to intercept the DataSource, from there intercept Connection, and then use regular synchronization tools to choose when the ResultSet is released back to the thread. If you try and do it at the level of individual reads/writes on a socket the test code will end up over-fitted to particular (undocumented) network protocols.

I haven't done that in my own deterministic testing framework because in most cases database access is fully synchronous and the concurrency problems arise inside the database itself. It might be interesting to play with H2 modifications to expose those.

Subject: Custom scheduler: Using loom for deterministic simulation testing

Hi,
I have also been looking into deterministic simulation on the side and belatedly saw some interest about it on the loom email list with the "Custom scheduler: Customize current time and timed waits" thread. I wanted to briefly expand on the topic of using Loom to make deterministic simulation testing more easily available to the java community.

BLUF:  Deterministic simulation testing makes multi threaded logic single threaded and fuzz tests the execution order, greatly simplifying discovery of race conditions and deadlocks. See this blog post by Ao Li<https://aoli.al/blogs/jdk-bug/> for an example doing this in java and the paper behind it  Fray: An Efficient General-Purpose Concurrency Testing Platform for the JVM<https://arxiv.org/abs/2501.12618>.

The above explanation omits how hard it is to actually make java or any language deterministic. This is where James Baker had a clever idea<https://jbaker.io/2022/05/09/project-loom-for-distributed-systems/> of using Loom, since we could replace the virtual thread scheduler with a deterministic one, Loom does most of the work for us without any extra frameworks. This works brilliantly, however there are three main caveats:

  1.  Its not easy to replace the virtual thread scheduler
  2.  The aforementioned scheduler has no understanding of delays so any Thread.sleep or Object.wait introduces continuations back into the scheduled execution pool non-deterministically. This affects the execution order so bugs can't always be reproduced.
  3.  IO also introduces continuations back to the scheduler execution pool non-deterministically.

The first issue can currently be solved by using reflection to make the virtual thread constructor public<https://github.com/ryeats/loom-dst/blob/main/src/main/java/org/example/SchedulableVirtualThreadFactory.java>. The second issue can currently be solved by controlling system time by replacing the byte code for all calls to System.nanoTime(), System.onCurrentTimeMillis() and Instant.now() using an agent at runtime<https://github.com/cmu-pasta/fray/blob/main/instrumentation/base/src/main/kotlin/org/pastalab/fray/instrumentation/base/visitors/TimeInstrumenter.kt>. The third likely has no general solution but I am interested in hearing ideas.

Even if there is no solution to IO non-determinism and developers have to stub out all IO, deterministic simulation is still an incredibly promising tool for making concurrent and distributed systems programing much simpler and safer. I think because of this use case there would be a lot of benefit if the Loom API allowed instrumenting the scheduler, even better if we could access the DELAYED_TASK_SCHEDULERS which understand delays.

Thank you for your time, I have been super excited to use virtual threads and amazed by the ingenuity that brought them to java.

Ryan

Race detectors are great but struggle to find problems that span multiple services in a distributed system.

FoundationDB and Antithesis do seem to have had success with deterministic testing, although the way Antithesis works doesn't require language runtime support (I think they use a custom hypervisor). FDB used a coroutine framework to do it, and supposedly they did find plenty of bugs in sim.

The big question is not whether these techniques find bugs (they do), but to what extent it should be done at the language runtime level vs the operating system. The latter can flush out more bugs, but the former can be easier to deploy and might have better observability.

If you follow the ?JDK bug? you?ll see it?s not a bug?

Personally I think the whole idea of synchronous testing of asynchronous systems is a fools errand? but never the less, I think something like the race detector in Go would be far more useful than a sync testing framework.

Hi,

We're also working a Deterministic Simulation Testing on top of loom for
some times now and though
you might be interested by this feedback:

One goal of our DST is to be able to run applications without having to
change application
code. To do so, we did a lot of trickery in JDK API using Agent (rewired
System.currentTimeMillis(),
System.nanoTime(), jdk.internal.misc.VMn ...). We're also doing call-site
instrumentation in application
code to replace every new Thread() by Thread.ofVirtual().start() (all
virtual threads are backed by a
single-platform thread, effectively a run loop). One limitation is that
this does not work for
`class Foo extends Thread'. Effectively application code must be changed to
replace 'extends Thread'
constructions by using composition. I don't think there is any solution to
this.

Another challenging aspect which might benefit from a JDK modification is
dealing with object monitor.
Since JDK 24, object monitor in virtual-threads don't pin the
carrier-thread anymore. The mechanism relies
on a queue which is polled by a thread-unblocker platform thread. To keep
determinism, we rewrote the
"unblockVirtualThreads()" loop (through Agent) and we select and push
unblocked pending virtual-thread
backed by the DST into another queue which is polled by the run-loop after
every iteration (while the
threads not backed by the DST are unblocked immediately). That appears to
work but is really inefficient
in addition to being complex: it requires checking for every virtual thread
backed by the DST whether
it is present in "onWaitingList". At that time, we made the choice to not
modify the JDK but that
maybe something we could revisit given the recent interest on this topic
appearing on this list.

ImmutableCollections (SALT32L and REVERSE) is another source of
non-determinism that we "fixed" with
our Agent. It would be helpful if the JDK provided a property to set the
seed (but I can see also how
doing so would kind of defeat the purpose of SALT32L).

ThreadLocalRandom.current() was also challenging as it is not possible to
provide a seed. We ended to
rewire #nextSeed() to the DST's Random#nextLong()

Regarding Object#hashCode()/System.identityHashCode() we don't have a
solution. So far we think they
could only impact iteration order of Hash(Map|Set) to which we're
evaluating replacing these by
LinkedHashMap/LinkedHashSet.

It feels like some localized modifications in the JDK would bring enough
flexibility to simplify our Agent
drastically. Otherwise, we'll probably have to adapt it for every JDK
version.  I'll try to take the time to propose
a PR about these to make the discussion more concrete.

Best Regards,
Yannick.

It certainly seems like a custom OpenJDK build would be an easier path for something like this. 

I am curious though - what if the application code uses async native type calls (NIO). What would be synchronous testing in this? I assume it would have to behave as if it was synchronous - callback immediately called - but that?s not how it works in the real world - so what are you testing ?

All that is quite early stage but we have a tiny network simulator PoC
(based on the blocking Socket API) which is deterministic and allows us to
inject fake failures and latencies.
We don't use async I/O anymore, thanks to Loom. No async, no callback.

Subject: Race condition in custom schedulers example
Message-ID: <CAL4QsguAUuExwhWed=XNeZ3ZytkbHbLM3vaEota=DRSwkdEq_w@mail.gmail.com>

Hello,

I am relaying a comment from my colleague Justin Bassett on one of the
examples in
https://github.com/openjdk/loom/blob/fibers/loom-docs/CustomSchedulers.md/

---

I believe there?s a race condition in the example in CustomSchedulers.md (
https://github.com/openjdk/loom/blob/8540bb13940fb6d2ce8b5fc25ba8e681665fd8b8/loom-docs/CustomSchedulers.md#threadvirtualthreadtask).
In particular, the `vthreadTask.attach(null)` can race with the earlier
`vthreadTask.attach(new Context(...));`. This happens because the virtual
thread can be scheduled again as soon as its run continuation finishes
under `vthreadTask.run()`, so if the platform thread it was bound to
deschedules and the virtual thread is then scheduled on a different
platform thread, the newly scheduled task?s call to `vthreadTask.attach(new
Context(...));` races with the first platform thread?s
`vthreadTask.attach(null);`.

```
@Override
public void execute(Runnable task) {
    pool.submit(() -> {
        var vthreadTask = (Thread.VirtualThreadTask) task;
        vthreadTask.attach(new Context(this, Thread.currentThread()));
        try {
            vthreadTask.run();
        } finally {
            vthreadTask.attach(null);
        }
    });
}
```

This could be avoided by using a more complicated attachment that includes
a lock that blocks the new platform thread until the first platform thread
finishes the remaining post-run tasks.

It may also be worth mentioning the risk of deadlocks with the virtual
thread: any locks that we might block on in this custom scheduler code must
not be held by the virtual thread, else if it deschedules while holding the
lock, our custom scheduler deadlocks.

Yannick,

  Thank you, this is very useful information! It's a good point about
extending Thread since ForkJoinWorkerThread will be problematic for
the common fork join pool which is used by .stream().parallel().
Additionally worth noting that GC pauses in the middle of a non
blocking code, JIT changes which can cause race conditions and
accessing volatiles won't necessarily be tested fully when using
virtual threads to simulate execution deterministically.

That being said not all indeterminism will affect execution enough to
matter either, so despite these extensive lists I still believe that
Loom with a deterministic scheduler will be useful and I am glad to
hear others experimenting with this too!

Yep, Just using Thread::yield in the virtual thread should make it happen.
I was thinking to rely on the thread state after a continuation's run, but
I see that it has a similar problem, Good catch!

Controlled concurrency testing (CCT) is not only about testing, but also
debugging. While the JDK issue mentioned in the blog post isn't technically
a bug, deterministic testing helps answer crucial questions like: Is my
application buggy? Is there an issue with my library? Am I using the wrong
library? The key advantage is that once you identify a bug, you can replay
it deterministically every time.

CCT benefits both single-process concurrent systems and distributed systems
by systematically exploring different thread interleavings, which
accelerates race condition discovery.  Go race detector is only for data
races, while many deterministic testing frameworks are designed to find a
broader range of race conditions.

Coincidentally, I'm currently interning at Antithesis
<https://antithesis.com/> where we're exploring the integration of Fray
with the deterministic hypervisor to combine the strengths of both
approaches. Fray excels at exploring thread interleavings but doesn't
handle network traffic, file I/O, and other sources of non-determinism.
Meanwhile, a deterministic hypervisor provides a deterministic environment
but relies on the kernel schedulers to run concurrent programs (could be
less efficient).

I really like the idea of using a customized user-space scheduler for CCT.
I know shuttle <https://github.com/awslabs/shuttle> and loom-rs
<https://github.com/tokio-rs/loom> are doing this. One challenge I?m
thinking about is that applications may mix both green threads with
physical threads. This could be messy because the CCT itself relies on
concurrency primitives.

>From my experience, handling all non-determinism within the JVM is
particularly challenging. When I attempted this approach in Fray, it made
the framework both cumbersome and fragile. In contrast, I'm impressed by
how elegantly Antithesis's deterministic hypervisor solves these issues for
Fray. For network and I/O operations, Fray can simply mark threads as
blocked when applications perform network operations and unblock them upon
completion while running inside the hypervisor.
https://github.com/cmu-pasta/fray/blob/main/core/src/main/kotlin/org/pastalab/fray/core/controllers/ReactiveNetworkController.kt
You may compare it against a version where Fray tries to manage the network
IO itself:
https://github.com/cmu-pasta/fray/blob/main/core/src/main/kotlin/org/pastalab/fray/core/controllers/ProactiveNetworkController.kt

For an open-source solution, RR <https://github.com/rr-debugger/rr>+Fray
sounds promising but I haven?t tried myself. Of course, this cannot test
distributed systems.

Yes, thanks. This is part of the prototype API that this project was 
experimenting with before JDK 19. It was dropped before the first 
preview but is back in the loom repo as one of two approaches to allow 
for further exploration into using different schedulers for virtual 
threads. So yes, it's possible to overlap so there are 2+ executing 
tasks for the same virtual thread. The virtual thread will only ever be 
mounted on a single carrier at a time but a custom scheduler can't 
currently tell this.

Right. If something is exposed then it it will need to come with several 
warnings that include never attempting to coordinate virtual threads and 
carriers with locking. I think Francesco's experiments with using Netty 
event loop thread as carrier rang into this before changing the event 
loop to be run in the context of a virtual thread.

An initial question for you:? Would I correct to say that the 
currentThread may change across suspension points when using these 
coroutines? Just asking as it isn't immediately clear if these 
coroutines are compatible with ThreadLocals and other APIs/features that 
depend on Thread identity.

In any case, the summary is that scoped values can only be safely 
inherited into "child threads" in structured contexts. Inheritance is 
one of the privileged operations and primitives that are needed to 
support structured use.? Right now the only API exposed that uses this 
is StructuredTaskScope (STS). We need a lot more feedback and real world 
usage before re-visiting the lower level construct that allows other API 
be developed.

There has been some experiments with inheriting into "child tasks", 
which I suspect is closer to what you are asking for. In particular 
there was initial interest into inheriting into the tasks supporting the 
stages of a parallel stream pipeline.? The main challenges with the 
experiments were in the areas of performance (esp. CountedCompleter) and 
reliable recovery (e.g. StackOverflowError). These experiments are 
parked right now. I read your mail as looking to reboot these explorations.

I understand why you are asking, and yes, currentThread may change
across suspension points. It's not a problem though in Kotlin Coroutines
because we have our ways to carry arbitrary data over threads.

We even have a way to preserve ThreadLocals:

    runBlocking(Dispatchers.Default) {
        // https://kotlinlang.org/api/kotlinx.coroutines/kotlinx-coroutines-core/kotlinx.coroutines/with-context.html
        // https://kotlinlang.org/api/kotlinx.coroutines/kotlinx-coroutines-core/kotlinx.coroutines/as-context-element.html

        // ThreadLocal set by withContext + asContextElement are preserved
        withContext(local.asContextElement("Will be restored")) {
            // suspension point
            delay(1.seconds)

            // Prints "Will be restored"
            println(local.get())
        }
        // Prints "null"
        println(local.get())

        local.set("Won't be restored")

        // suspension point
        delay(1.seconds)

        // May randomly print "null" or
        // "Won't be restored"
        println(local.get())
    }

It doesn't work perfectly as you can see. The data is carried over only
if it's set in a "managed", structural way that coroutines framework
understands. And that's why we generally advise against using Coroutines
together with ThreadLocals.

Theoretically, we could even preserve all ThreadLocals between
suspension points if there were an API to capture all current
ThreadLocals, which is probably unfeasible from the design point of
view. And anyway, at the moment, I don't think that it's the right API
to have, and I am not asking for it.

I see and respect this point, but it's exactly the point I'm trying to
challenge. I feel that public and safe inheritance API is possible so
that it doesn't have to be the privileged operation.

But I do feel that you understood me, so I just reiterated my point.

> Right now the only API exposed that uses this

BTW, it's the API we can already use/abuse to get Scoped Values work in
Coroutines:
https://gist.github.com/nikitabobko/e923d187efb7832f1cfb56a66d20b8df

The downside is that users lose the flexibility to choose which threads
they want to run their Coroutines on (e.g. UI main thread is no longer
an option), which feels like an artificial limitation.

And there are multiple existing other ways on how we can
support ScopedValues, each of them having different trade-offs:
https://youtrack.jetbrains.com/issue/KT-78467
(it's just for the reference, I don't expect you to read all of this)

If by "child tasks", you mean
arbitrary-3rd-party-framework-structured-child-tasks, then yes :)

If you mean ForkJoinTask specifically, probably not so much, but it'd be
a good start, I guess.

Ha, interesting. It didn't cross my mind that ScopedValues make sense in
parallel streams, thank you for sharing.

Anyway, thanks, Alan, for your answer. It's nice to see that there is
also a parallel streams use case, I hope to see if something comes of it
in the future. I am happy to answer whatever questions about the
Coroutines-in-Kotlin-use-case.

Let me take a step back for a moment to consider the implications of
this.

The Java rules of access control apply here: if a field is not
accessible, then you may not do anything with it. Those Java rules
apply to scoped values, but we add another: if a field is not
accessible to you, you may not extend its lifetime, or cause it to be
accessible in some other context.

By analogy, it's a fundamental principle in law: you can't transfer
title to something you do not own.

We do this because you cannot know the purpose of every element of a
set of scoped values you've just captured. Some of them might be
critical to the integrity of the system, for example the address of a
region of raw memory such as a frame buffer. For this reason we can't
allow a framework to extend the lifetime of a scoped value beyond the
point its binding context ended.

However, it is straightforward to create a scoped value class of your
own that has any properties you wish, including different inheritance
rules. Given a ScopedValue.Carrier that binds some values, start your
thread with aCarrier.run(task). Would this work for you?

Andrew.

Yes, I understand what you mean, and I agree. The lifetime of a
ScopedValue variable belongs to its owner.

Who defines the lifetime? The current stack inside Carrier.run defines
the lifetime. Whilst the stack is alive, all so far bound ScopedValues
remain alive. StructuredTaskScope takes advantage of this fact. Whenever
users call StructuredTaskScope.join (and block the parent thread by
doing that), they effectively make sure that the stack will live long
enough, so that all ScopedValues could be safely accessed in child
virtual threads.

Please note that the API shape that I'm suggesting replicates
StructuredTaskScope, and it doesn't do anything that couldn't be already
achieved with the existing StructuredTaskScope API (Or I explained it
poorly).

Unfortunately for me, StructuredTaskScope is two things in one package.
It's structural virtual thread factory and it's ScopedValues structural
forking API. I don't want the first thing, I only want the second one.

So let's take a look at what happens if you try to extend the lifetime
of a ScopedValue beyond its proper boundaries by using
StructuredTaskScope:

    var value = ScopedValue.<String>newInstance();
    var reference = new StructuredTaskScope[]{null};
    ScopedValue.where(value, "Duke")
            // java.util.concurrent.StructureViolationException
            .run(() -> {
                reference[0] = StructuredTaskScope.open();
            });

You get a StructureViolationException from Carrier.run. It means that
the very same thing should happen with the API that I'm suggesting:

    var value = ScopedValue.<String>newInstance();
    var reference = new ScopedValue.Snapshot[]{null};
    ScopedValue.where(value, "Duke")
            // java.util.concurrent.StructureViolationException
            .run(() -> {
                reference[0] = ScopedValue.snapshot();
            });

Note: I snatch the StructuredTaskScope/ScopedValue.Snapshot into a
reference variable for extra clarity. We would get the same exception
even without doing that because we didn't close our AutoCloseables.

I guess that Carrier.run(), ScopedValue.snapshot(), and 
Snapshot.forward() would do some sort of handshake to make sure that 
every Snapshot has been join()ed at the end of Carrier.run(). I guess 
that would work if we could figure out a sound way to do it, but at 
present we don't need to do much of this. I take your point about the 
StructuredTaskScope complications, though.

I'm hoping that at some point in the future we can get a secure form of 
try with resources, one that doesn't rely on the user to call close(), 
but that's a long way off.

Most people who have asked about capturing scoped values have wanted to 
use them in an unstructured way, but your request is quite different. 
Given that a StructuredTaskScope can work with any ThreadFactory, why do 
you need to replicate its working? What do you need to do differently?

I'm still curious about this:

I'm curious as to what makes you doubt that it can be done in a sound
way. StructuredTaskScope already does that, doesn't it?

Andrew Haley wrote:

Great question. I'm trying to make kotlinx.coroutines seamlessly work
together with ScopedValues. Similar to how StructuredTaskScope endorses
structural concurrency, kotlinx.coroutines endorses structural
concurrency as well.

But StructuredTaskScope and kotlinx.coroutines use threads in a
different way. For StructuredTaskScope, thread is *the unit* of
structural work. For kotlinx.coroutines, thread is just a resource (like
memory) that we use to run coroutines on.

Coroutine is *the unit* of structural work in the kotlinx.coroutine
world. Coroutines are lightweight threads, and they are implemented via
async/await code-coloring and Continuation Passing Style transformation
(CPS-transformation) made by the Kotlin compiler.

kotlinx.coroutines framework allows to choose which threads users want
to run their Coroutines on. For example, UI main thread is an important
case where users care on which thread Coroutines run on.

Unlike in StructuredTaskScope, threads that we run Coroutines on could
had existed long before ScopedValue.Carrier.run() was called.

We don't use threads structurally. But the jobs (coroutines) that we
submit on those threads are structural. And the child coroutines are the
place where I want to forward ScopedValues to. Not child threads, but
child coroutines. Unfortunately for us, StructuredTaskScope assumes that
*the unit* of structural work is thread.

My task is to seamlessly integrate kotlinx.coroutines and ScopedValues.
Unfortunately, your suggestion doesn't work for us, because we would
need to ask users to manually pass ScopedValue.Carrier bindings to
kotlinx.coroutines.

StructuredTaskScope is part of the system, and is trusted code. It uses 
facilities that are necessary in the standard library that we don't want 
to expose. If any bugs are found in StructuredTaskScope we can fix it.

OK, thank you. It really helps me to understand the root problem.

I think I've got a fair idea of how Kotlin coroutines work under the 
hood. Is it your intention that a set of ScopedValue bindings be 
associated with a coroutine, and that ScopedValue bindings be captured 
at the point at which the coroutine is suspended, and re-bound later
when the coroutine is resumed?

I'm baffled. Your proposal involves invoking bindings.forward() when 
(re)starting a task:

                         pool.submit(() -> {
                             bindings.forward(() -> {

This has to be explicit, and has to be done when there are no bound 
scoped values. Why can't your implementation do it?

Glossary.

*suspend* functions in Kotlin are code-colored functions. `suspend` is
keyword that users put on their functions and functional types. All
suspend functions and lambdas undergo a CPS-transformation performed by
the Kotlin compiler. In other languages, such functions are commonly
referred as *async* functions. I may interchangeably call them either
async or suspend functions.

Correct.

I'd like to take a step back and mention that there are actually two
possible integrations between ScopedValues and kotlinx.coroutines.

*Integration 1.* kotlinx.coroutines should provide an utility function
that would be an analog of ScopedValue.Carrier.run, with the slight
difference that the function must be suspend, and the lambda that it
accepts must be also suspend. That's the integration for which we don't
need anything else on top of what ScopedValues already provides.

*Integration 2.* Similar to how child threads in StructuredTaskScope
have access to all ScopedValues of their parent thread, we want to
forward all ScopedValues from the blocked parent thread (yes, parent
thread, not parent coroutine, please read further) to children
coroutines. For that kind of integration, we need something along the
lines of what I've described at the beginning of the thread.

In kotlinx.coroutines, we want to provide both integrations.

I think the misunderstanding may be comming from the fact that we were
thinking about different kinds of integrations.

For integration 1, we indeed are going to do something along the lines
of what you describe with ScopedValue.Carrier object.

To better understand integration 2, I think it is easier to see what I
mean by looking at Kotlin code (I understand that you may not be
familiar with Kotlin, I tried to make it as Java as possible):

    // The lambda below is obviously non-suspend,
    // we just call a Java API from Kotlin
    ScopedValue.where(scopedValue, "Duke").run({

        // Below is a non-suspend lambda with a single CoroutineScope
        // parameter. I extracted the lambda to a "spawner" variable
        // because of some Kotlin-unrelated-details
        val spawner: (CoroutineScope) -> Unit = { scope: CoroutineScope ->

            // Spawn a child coroutine and schedule to run it on UI main
            // thread.
            scope.launch(Dispatchers.Main, block = { // suspend lambda

                // Right now, it fails with:
                //     NoSuchElementException: ScopedValue not bound
                // My goal is make it return "Duke"
                println(scopedValue.get())

                // Non blocking suspension point.
                // delay is a suspend function and can be called only
                // from other suspend functions
                delay(1.second)

                // Right now, it fails with:
                //     NoSuchElementException: ScopedValue not bound
                // My goal is make it return "Duke"
                println(scopedValue.get())

            })
        }

        // runBlocking runs the lambda and keeps the current thread
        // blocked until all the spawned child coroutines are done.
        runBlocking(block = spawner)
    }

- Kotlin's runBlocking function is identical to Java's
  StructuredTaskScope.open() function
- Kotlin's CoroutineScope.launch function is identical to Java's
  StructuredTaskScope.fork function
- Kotlin's CoroutineScope is identical to Java's StructuredTaskScope
- In java, one has to manually do StructuredTaskScope.join(). In Kotlin,
  we do it implicitly at the end of runBlocking function.

Coroutines are not magical. Effectively, CPS-transformation slices
suspend functions by their suspension points. And under layers of
abstractions, kotlinx.coroutine still submits those slices to whatever
thread by doing old and boring threadPool.submit().

Suppose that the API that I'm suggesting at the beginning of the thread
existed, then at the beginning of runBlocking implementation, I'd
capture all the current bindings, and stash them inside a CoroutineScope
instance. To keep everything structural and sound, I obviously call
ScopedValue.Snapshot.join() and ScopedValue.Snapshot.close() on the
stashed bindings at the end of the runBlocking function.

And once we pass all further layers of abstractions, and get to the
point when we actually need to submit a sliece of a coroutine on a
threadPool. Instead of calling threadPool.submit(coroutineSlice), we
would just wrap coroutineSlice into ScopedValue.Snapshot.forward call:

    threadPool.submit(() -> {
        coroutineScope.stashedParentScopedValueBindings.forward(() -> {
            coroutineSlice.run();
        });
    });

so that a child coroutine has access to ScopedValues of its blocked
parent spawner thread, yay! Task accomplished, Java is once again a
great platform for integration, Nikita is happy. Mic drop.

Basically, the difference between these two integrations is that the
first integration bridges suspend world with the very same suspend world
with ScopedValue bindings in the middle. But the second integration
bridges Java's non-suspend world where some of ScopedValues bindings
already existed with Kotlin's suspend world.

The whole point of virtual threads is to avoid coroutines / async functions. 

Why would the Java team spend anytime on this?

I'm not sure that's really true. Continuation-passing style and 
coroutines have their uses even in the presence of virtual threads, as 
do things like generators. I don't much like coloured functions (does 
anyone?) but CPS is more general than vthreads.

I?ve previously proven you don?t need coroutines to implement generators. 

Code is here https://github.com/robaho/generators

As for other worthwhile CPS usages I guess you?d have to show me because I doubt it.

IIRC, integration 2 requires merging values bound to the continuation with
values bound to the thread at each "resume" point and then provided to the
coroutine. Is this not the domain of the transformer or scheduler?
shouldn't this be implemented in that layer? This way, Kotlin would
guarantee structural integrity -- there would be no way for the user to
fail to satisfy runtime requirements. Proposals which require the user to
"close" bindings remove from the platform the surety of structural
integrity, requiring "checks" to be introduced at code paths meant to
be blazing fast.

In effect we already do exactly this with Java's 
jdk.internal.vm.Continuation class, but that's not available to client 
code such as Kotlin. So sure, it's the job of the transformer, but there 
isn't an API that such a transformer can use.

May I inquire: what is a transformer? I briefly read some of the
jdk.internal.vm.Continuation code, but apparently not enough.

Having currentThread change in a thread of execution will break a lot of 
things. I'm thinking of unlock methods throwing 
IllegalMonitorStateException if there is a suspension point after 
calling into some Java code that acquires a lock. Same thing with 
closing a confined arena throwing WrongThreadException, and dozens of 
other parts of the system that make use of the current Thread or current 
thread ID. This is on top of all methods that may block and all the 
serviceability features/APIs that are also thread focused. So while the 
discussion here is on inheriting ScopedValues, it looks like it is 
dwarfed in comparison to all the issues that may arise when executing 
Java code.

Is this Android or are you saying that the AWT event dispatching thread 
(or the JavaFX application thread) can be used as a carrier for these 
coroutines?

It's the close method (not join) that is specified to not continue until 
all threads forked in the scope have finished. Structure is enforced at 
runtime. There is a per-Thread scope stack: open is a push, close is 
pop. Same thing with ScopedValue where run (or call) does a push, 
executes the ops, then pops. Code executing in a thread can't pop out of 
order and can't terminate with a non-empty scope stack.

Thinking about this some more, here is your example:

         public static void main(String[] args) {
             ScopedValue.where(userName, "Duke").call(() -> {
                 try (ScopedValue.Snapshot bindings =
                          ScopedValue.snapshot()) {
                     try (var pool = Executors.newFixedThreadPool(1)) {
                         pool.submit(() -> {
                             bindings.forward(() -> {
                                 // Should prints "Duke"
                                 System.out.println(userName.get());
                             });
                             // Throws
                             //
                             // java.util.NoSuchElementException:
                             //     ScopedValue not bound
                             System.out.println(userName.get());
                         }).get();
                     }
                     bindings.join(); // may block
                 }
                 return null;
             }); // may block
         }

I think we can make this robust if and only if ScopedValue call() blocks 
until every forward() (or, equivalently, every bindings.join()) has run 
to completion. This approach may also give us a way to support parallel 
streams, etc., without compromising scoped values' temporal and 
structural invariants. This is an attractive thought.

Unfortunately, even though failing to wait for children to terminate 
would be a coding error, it couldn't cause an exception to be thrown 
because that would leave threads running after the scope that launched 
them had exited. We could try to interrupt the blocking threads, but if 
they didn't respond we'd be stuck.

Also, doing this does sort-of imply that there has to be a handshake at 
every scoped value binding. It also means that ScopedValue.Snapshot 
would need to be mutable in order to ensure that a Snapshot instance 
couldn't be reused once it was join()ed.

Subject: [ScopedValue] best way to conditionally bind a value ?
Message-ID: <CAL6Huih1j8BqnpA=9ScPTBigdeyVAvn-L+F6UdeKftcS0LWWSQ@mail.gmail.com>

Hello

After using the ScopedValue for a few days, I'm wondering if there is a
better way to conditionally bind a value than doing the following :


public static final ScopedValue< Locale > ACCEPT_LANGUAGE =
ScopedValue.newInstance();
public static final ScopedValue< String > USER_ID =
ScopedValue.newInstance();

final Locale acceptLanguage = getAcceptLanguageFromHeader( httpRequest );


if( acceptLanguage == null ) {
    ScopedValue
        .where( USER_ID, uid )
        .call( MyClass::myStaticCallableMethod );
} else {
    ScopedValue
        .where( USER_ID, uid )
        .where( ACCEPT_LANGUAGE, acceptLanguage )
        .call( MyClass::myStaticCallableMethod );
}


The point for me of doing so, instead of simply setting a null
acceptLanguage, is to have a more readable code afterward :


private String myStaticCallableMethod() {
    final Local localToUse = ACCEPT_LANGUAGE.orElse( A_DEFAULT_LOCAL );


    ...
}


What is your advise about it ?


Best regards

I personally would try this variant,

Carrier carrier = ScopedValue.where( USER_ID, uid );
if( acceptLanguage == null ) {
    carrier = carrier.where( ACCEPT_LANGUAGE, acceptLanguage );
}
carrier.call( MyClass::myStaticCallableMethod );

If the user ID and accept language were (explicit) method parameters 
then you might write:

if (acceptLanguage == null) {
 ??? MyClass.myStaticCallableMethod(uid);
} else {
 ??? MyClass.myStaticCallableMethod(uid, acceptLanguage);
}

With implicit method parameters you've got the same if-then-else so I 
don't think it is terrible.

Is there any reason why the caller can't bind ACCEPT_LANGUAGE to 
A_DEFAULT_LOCALE so that the callee doesn't need to handle it? That 
would change the usage to:

ScopedValue
 ??? .where(USER_ID, uid)
 ??? .where(ACCEPT_LANGUAGE, (acceptLanguage != null) ? acceptLanguage : 
A_DEFAULT_LOCALE)
 ??? .call(...);

It would then be a bug f myStaticCallableMethod were called without 
bindings for either.

Hi Davor

Thank you for your reply

Indeed, I had a thought about doing such a thing

But with this solution, involving the direct usage of a Carrier, a trouble
would arise :

What if I only had to manage a single optional ACCEPT_LANGUAGE scope value ?

I wouldn't have other choice to either write a cumbersome code on the
caller side :

if( acceptLanguage == null ) {
    ScopedValue
        .where( ACCEPT_LANGUAGE, acceptLanguage )
        .call( MyClass::myStaticCallableMethod );
} else {
    MyClass.myStaticCallableMethod();
}


or to write something more straightforward :


 ScopedValue
    .where( ACCEPT_LANGUAGE, acceptLanguage ) // null binding is allowed
here
    .call( MyClass::myStaticCallableMethod );


... but in that later case, it would rule out the use of .isBound() or the
.orElse() method on the callee side :

private String myStaticCallableMethod() {
    final Local localToUse = ACCEPT_LANGUAGE.get() == null
        ? A_DEFAULT_LOCAL
        : ACCEPT_LANGUAGE.get();

    ...
}


I feel like this is because there is no possibility to get an "emtpy"
carrier from the ScopedValue API, but on the other hand, I guess it's a
conception decision that has been made on purpose, else it would have
enabled writing useless code such as :

ScopedValue

    .getEmptyCarrier()

    .call( MyClass::myStaticCallableMethod );


best regards


Benoit

Hi Alan

Thanks for your advice !


As mentioned in my latest reply to Davor, the goal of this badly chosen
example of mine is to point out the edge case where there is only a single,
optional, ScopedValue to manage :p

*Is there any reason why the caller can't bind ACCEPT_LANGUAGE to
A_DEFAULT_LOCALE so that the callee doesn't need to handle it? :*


Yes, there is one :

This code sample is inspired from an actual Tomcat's Filter, which is
general purpose.

I.E. it's only there to extract certain generic header parameters from
calls to a REST API server, and it's used in each use cases

So it's a very technical oriented piece of code, and that's why from my
point of view its purpose is not to choose which is the default accept
language to be used.

Sounds better to me to hand over this functional responsibility to each
endpoints.

Best regards

Benoit

Subject: Request for Custom Carrier Thread Group Support in Project Loom
Message-ID: <CAH_RHgH0-+=gNBaaFXnoj3V8qbykFE1mecM3J85-hmEyNLgVOw@mail.gmail.com>

Dear Loom Team,

First, thank you for the incredible work on Project Loom. Virtual threads
are a game-changing feature that?s making concurrency in Java much more
efficient and scalable.

While exploring virtual threads in JDK 21+, I noticed that there is
currently no public API for assigning a custom carrier thread pool (e.g.,
via Thread.ofVirtual().scheduler(...)) or accessing the current carrier
thread (e.g., Thread.currentCarrierThread()). I understand that this
abstraction is intentional to preserve simplicity and portability.

That said, I?d like to propose a possible extension to the current model:
the ability to define and manage *multiple groups of carrier threads*,
which virtual threads can be scheduled onto. With such support, developers
could:

   -

   Spin up dedicated pools of carrier threads for different classes of
   virtual workloads (e.g., I/O-heavy vs CPU-heavy),
   -

   Pause/resume or assign priorities to these carrier groups,
   -

   Integrate carrier thread group control into custom runtime environments.

This flexibility could enable advanced scenarios such as runtime
observability, load isolation, resource throttling, or tighter integration
in frameworks with custom concurrency policies.

For context, I attempted something like this using:


ExecutorService carrierThreadPool = Executors.newFixedThreadPool(...);
Thread.Builder.OfVirtual builder =
Thread.ofVirtual().scheduler(carrierThreadPool);

...only to find that the .scheduler(...) method is not available, and
currentCarrierThread() is also inaccessible due to being non-public.

Are there any plans to support this level of carrier group configurability
in future versions of the JDK or Project Loom? Even an opt-in or
expert-mode API would go a long way in allowing more fine-tuned control for
advanced users without impacting the simplicity that Loom provides by
default.

Thanks again for the amazing work you?re doing and for considering this
request.

Best regards,
Victor Madu
