Subject: Feedback about structured Concurrency and proposing of a new
 functional interface akin runnable
Message-ID: <CADFQZ76GB4FG9awaqEY5zFE8DGecYEq7F6BazzyTRuiS2MyxbQ@mail.gmail.com>

I hope this message finds you well. Thank you for all the work you are
doing to improve the Java platform.

I wanted to share some thoughts from a small experiment I?ve been running
with structured concurrency. The idea was to mimic (to some extent) Go?s
goroutines and channels, modeling an N:M producer?consumer fan-out using
StructuredTaskScope together with ArrayBlockingQueue as a ?channel.? The
intention is to build groups of task pipelines step by step that can be
executed in parallel.

Here?s a simplified snippet that captures the idea:

void main(){
    var producerChannel = new ArrayBlockingQueue<HttpRequest>(100);
    var consumerChannel = new ArrayBlockingQueue<HttpResponse<String>>(3);
    var client = HttpClient.newBuilder().build();
    var request = HttpRequest.newBuilder()
        .uri(URI.create("some url"))
        .build();
    try(var routine = StructuredTaskScope.open()){
        for(var i = 0; i < 100; i++){
            routine.fork(() -> sendRequest(producerChannel,
consumerChannel, client));
            producerChannel.put(request);
        }

        routine.fork(() -> processResponse(consumerChannel));
        routine.join();

    } catch (InterruptedException e) {
        throw new RuntimeException(e);
    }

}

Void sendRequest(ArrayBlockingQueue<HttpRequest> producerChannel,
                          ArrayBlockingQueue<HttpResponse<String>>
consumerChannel,
                          HttpClient client) throws InterruptedException,
IOException {
    var req = producerChannel.take();
    var res = client.send(req, HttpResponse.BodyHandlers.ofString());
    consumerChannel.put(res);
    return null;
}

Void processResponse(ArrayBlockingQueue<HttpResponse<String>>
consumerChannel) throws InterruptedException {
    for (var i = 0; i < 100; i++){
        var value = consumerChannel.take().body();
        println(value);
    }
    var value = consumerChannel.take().body();
    println(value);
    return null;
}

One thing I noticed is that having to declare Void and return null
introduces a bit of noise. This ceremony is required because Runnable
doesn?t allow checked exceptions in its contract (and never will, for
backwards compatibility). Yet, in practice, many real-world tasks don?t
return values directly ? instead, they write to or consume from buffers.

This makes the Void return type and return null feel redundant. I was
wondering: would it be worth considering the addition of a Runnable-like
functional interface that permits checked exceptions?

Thank you for your time and consideration. I?d love to hear your thoughts.

Best regards and always yours.

Full agreement on the suggestion to have the Runnable-like interface that
throws. It's common enough that it would be very useful for me. Void was a
workaround for a bad situation, but it doesn't mean we should have to be
stuck with it for a new API.

Runnable and Callable are familiar to all of APIs in this area. We've 
avoided introducing throwing-Runnable or throwing-Supplier functional 
interfaces as adding any throwing interface to j.u.function opens the 
door to requests to add more. It might also be that someday there are 
changes to the language for exception transparency or maybe allowing 
overriding with an unboxed return. So maybe in the future need for such 
interfaces may go away (I can't speak to any specific plans of course, 
instead just saying that we've been conservative about adding throwing 
variants that could potentially be obsolete in the future).

So far, the changes are very modest [1]. These changes are in the fibers 
branch of the loom repo. There is a draft JEP [2] but will likely have 
more edits/review before it can be submitted.? It is linked to recently 
generated API docs.

Hi,

I was bit confused, and did not find mailing list that is best suited
to ask questions about stable values.

Someone please point me to the right channel/maining-list

core-libs-dev would be the best place to bring feedback, esp. if you 
have tried it out in earnest.

Hello Davor Hrg,

Here is the JEP for Stable Values -- https://openjdk.org/jeps/502. On the
top, you will notice that it says Discussion. That tells you the address of
the mailing list to contact with any of your questions.

So in this case, that would be @core-libs-dev <core-libs-dev at openjdk.org>.
Resend your message over there.

Hey Yuval,

I'll leave it to others in the group for a proper answer, but I think I can
say it would be useful to include the exact issue. I did a look through JBS

one about virtual thread parking with InetAddress. Is that what you're
talking about?

Thanks,

net-dev would be a better replace to discuss this.? As I mentioned in 
JDK-8357160 [1], I think it would be useful to know if it common for 
deployments to have CAP_NET_RAW/equivalent or whether the TCP 
implementation is more commonly used. If the TCP implementation were to 
re-written in Java (not hard) then it would be "virtual thread friendly" 
in the sense that waiting for SYN-ACK would release the carrier to do 
other work.

The implementation of this method blocks in native code so pins the 
carrier, it needs a re-write, too many other areas have been higher 
priority to date. A thread pool would help with a small number of 
virtual threads calling InetAddress::isReachable but isn't going to 
scale when the typical timeout specified to the method is in seconds.

Subject: New candidate JEP: 525: Structured Concurrency (Sixth Preview)
Message-ID: <20250922144655.A68A1518@naskeag.niobe.net>

https://openjdk.org/jeps/525

  Summary: Simplify concurrent programming by introducing an API for
  structured concurrency.  Structured concurrency treats groups of
  related tasks running in different threads as single units of work,
  thereby streamlining error handling and cancellation, improving
  reliability, and enhancing observability.  This is a preview API.

- Mark

Subject: Remark on the StructuredTaskScope API of Java 25
Message-ID: <715342229.35882407.1758728261503.JavaMail.zimbra@univ-eiffel.fr>

Hello,
I know that the API will change a bit in 26, but this is a review of the API of 25.

I find the new API (joiners + configuration) to be cleaner than the previous iteration (composition vs inheritance).

In Joiner,
  - onFork() and onComplete() should take a SubTask<T> and not a SubTask<? extends T>.
    This is Okay because SubTask is sealed, so the type parameter is covariant.

    Another way to see it is that instead of every implementation of onFork/onComplete doing an unsafe cast,
    the caller of those methods should do the unsafe cast.

  - allSuccessfulOrThrow() should return a Joiner<T, List<Subtask<T>>>, so the result is a List and not a stream.
    In terms of implementation, in result(), the code should be
      return Collections.unmodifiableList(subtasks);

  - awaitAllSuccessfulOrThrow should not use Void, but be typed like this
      <T, R> Joiner<T, R> awaitAllSuccessfulOrThrow()

    which means that the return type of join() can be any type.
    This allow users to type the result value null the way they want.
    
  - allUntil is missing a ? super, it should use a SubTask<T> (like in onComplete/onFork) and returns a List (like allSuccessfulOrThrow()), so it should be:

     <T> Joiner<T, List<Subtask<T>>> allUntil(Predicate<? extends Subtask<T>> isDone) {

And now two remarks,
 - is there a way to remove the limitation that the main thread (the one that have created the STS) can not access to SubTask.get(),
   because there is at least a case where i know that the task is finished before join() is called (see below).
 - is there a way to get a joiner that returns the list of subtask in the order if their completeness, not in the order of onFork() ?


regards,
R?mi

This restriction is there to ensure that the API is used as intended. 
Subtasks are forked individually and then joined as a unit. If the API 
allowed Subtask::get to be used before join then it would be very 
fragile as it would be like a "wait-less" Future::get. It might work 
sometimes, but if a subtask were slow then Subtask::get would throw ISE.

A Joiner can collect in its onComplete method so that will give you 
completion order. That said, I suspect you might be asking something 
different. Are you thinking about APIs such as CompletionService where 
you get a wakeup as subtasks complete rather join as a unit?

Hello R?mi,

> of Stream

This is a good suggestion. No need to pay for instances of Stream that you
won't use, especially if what you wanted was a List in the first place.

> awaitAllSuccessfulOrThrow() should use <R>
> instead of Void

I don't see how this would be useful. When would you care about the type of
null? I'm not even sure what that means.

> ordered by onComplete(), and not in the order
> of onFork()?

Maybe Subtask can track onFork() and onComplete() timestamps? Then you
could order yourself.

Can you explain this in more detail? I don't understand what you are saying

My use case is.a list of STSs, one using a joiner that returns null and one using a joiner that returns a List of subtasks, 
when i call join() on all the STSs by iterating the list, i wanted the same return type.

yes, i can, 
i was wondering if it would be a good idea to have this kind of behavior in a joiner provided by the JDK.

In a way, i think i want something that the STS is not. 

I want to be able to run the semantics of onComplete() but without the burden of managing the concurrency part, like if onComplete() was run by the main thread (and yes, i know it has a cost).

CompletionService is several things, you can get the subtask as they complete (1), this is run by the main thread (2) and it's a pull API (3). 

I want (1) and (2), but not necessary (3), so it's still a STS that join as a unit. 

As said above, what i think i want is a way to opt-in to get onComplete to be run by the main thread when join() is called.

Actually, you can not extract the values using the main from any subtasks until STS.join() complete, 
there is a specail check is Subtask.get() that check that if you are the main thread, join has to be called before. 

So if you write, 

try(var sts = STS.open()) { 
var subtask = sts.fork(callable); 

// we are before the join here 
IO.println(subtask.get()); 
// here you have a race between the main thread and the virtual thread that run the callable 
// so you can get spurious IllegalStateException 
// to make the user aware of that, SubTask.get() has a special case that throw is get() is called by the main thread before join() 
sts.join(); 

IO.println(subtask.get()); // this is fine, we are after the join(). 
} 

The problem, is that this check is a kind of weak, because you can write 

try(var sts = STS.open()) { 
var subtask = sts.fork(callable); 

// spurious STS are back ! 
Thread.ofVirtual().start(() -> IO.println(subtask.get())).join(); 

sts.join(); 
}

Subject: StructureTaskScope joiner naming
Message-ID: <284732572.36087138.1758781205048.JavaMail.zimbra@univ-eiffel.fr>

So currently we have those joiner defined in the JDK:
  - allSucessfulOrThrow()
  - anySucessfulResultOrThrow()
  - awaitSucessfulOrThrow()
  - awaitAll()
  - allUntil(predicate)

There are several issues,
- TS.join() always wait, so this is confusing because a joiner with a name that does not start with the name "await" still await.
  If you take a look to the doc, the prefix "await" seems to be used to convey the idea that the result of the STS.join() is null,
  i.e the joiner does not stores the forked subtasks in a list. 

- The other issue is the naming of awaitAll(), which is the shorter name, so people will be droven to use it by default, "it's the simpler",
  but unlike the other joiners, it does not cancel the other subtasks in case of failure, which is not the semantics you want by default.
  The name seems to imply that because it does ends with "OrThrow", it means that there is no cancellation.

- "allUntil" is a half-lie, it will correctly cancel the other subtask when one task validates the predicate but at the same time,
  STS.join() will returns all subtasks, not the ones until the predicate is true.
  The name "allUntil" only make sense if you see it as the concatenation of two orthogonal behaviors, "all" meaning STS.join() returns
  all subtasks and "until" meaning stop when the predicate is true.

I propose this renaming (in order):
- allSuccessful()
- anySuccessful()
- sucessfulVoidResult()
- noCancellationVoidResult()
- cancelWhen(predicate)

After that, i think we can be a little more fancy and see the fact that the implementation returns all subtasks as a separate concern,
thus enable composition:
- sucessful().all()
- anySucessful()
- sucessful()
- nonCancellation()
- cancelWhen(predicate).all()

With all() a default method that override onFork() and result() to respectively add each subtask in a list and blindly returns that list.

regards,
R?mi

Hello R?mi,

The method name join() makes perfect sense to me -- it joins all the
threads.

And more accurately, it isn't just waiting, it is joining! Remember that
STS with the default semantics (STS.open()) are those that it would have if
we did CompletableFuture.allOf().join().

Therefore, to base your name off of waiting instead of joining would be the
wrong semantics. The method name should remain as join() and should not be
called anything else. Especially not await().

Good point.

The name allUntil() leans heavily on the naming convention in order to make
sense, but reading it plainly definitely misleads you as to its actual
semantics.

Plus, I think your cancelWhen() suggestion is much clearer. Shame that it
must abandon the naming convention. At the end of the day, the naming
convention is useful, so I'd like any rename of this to maintain that
convention.

This isn't a very strong argument, but at the same time, I think you have a
point.

There is significant value in having the default semantics be attached to
the name that users might first reach for.

That said, I think noCancellationVoidResult() is a very poor replacement
name.

Here is my attempt at it.

allSuccessful()
anySuccessful()
awaitAllSuccessful()
awaitAllDontThrow()
allUntil(Predicate)

I can appreciate that SC API designers trying to avoid the Optional.get()
fiasco by trying to use the xxxElseThrow and xxxOrThrow naming structure.

But Optional.get() was a fiasco because of WHERE Optional was being used --
aka, as a return type of basically ANY METHOD that can say "I may not
return anything!". Its UBIQUITY is what made Optional.get() a disaster --
get() implies many things in many contexts, so it was not a wise name to
use.

Joiner, in comparison, is a far more constrained domain. I think we can get
away with having throwing be the assumed default. After all, we have to
write a giant try-with-ressources anyways. I think the programmer is in the
frame of mind to expect Exceptions. And that's ignoring the fact that
join() throws! And that's even FURTHER ignoring the fact that, at use-site,
the developer is not calling get() when they want to join.

How do you feel about my naming suggestions instead R?mi? I don't have a
good replacement for allUntil's name, and I don't want to use cancelWhen,
since it throws out the naming convention. But otherwise, how do you feel
about it?

Can you say more on this? Right now, preferring a stream works well. For 
a Joiner returned by allSuccessfulOrThrow it makes it easy to use 
join().map(Subtask::get) or other mapping function. Add .toList() to get 
a list. When using a Joiner created with allUntil then you may have to 
use a collector that partitions the subtasks into those that were 
successfull and those that didn't complete successfully.

It's only interesting to call Subtask::get in the main task (after join) 
or in a custom Joiner's onComplete when the thread that executed the 
subtask completes. The specified seat belt is to avoid a mistake in the 
main task where code might attempt to get the result before joining. It 
would of course feasible to specify it be not allowed from other random 
threads that happen to get a reference to the subtask, but it would add 
overhead to cater for a very off-piste usage.

A collection is more powerful than a Stream, you can always do more with a List than with a Stream 
(like indexed access). 

Yes, you can always call toList() on a stream, but you are asking to duplicate all the elements, 
here stream.toList() is semantically equivalent to a call to List.copyOf(), so it's slow if you have quite a lot of elements. 

So yes, it might be convenient for some use cases to return a stream than to call .stream() on the returned List, 
but you are trading convenience for performance.

Yes, it can be more convenient for some use cases. 

I'm not advocating that, but you can also do both, you can add a bunch of default methods like all(), stream(), iterator(), etc on the interface Jiner (see my other mail) but it also make the API bigger than it should be.

I think you misunderstood me, 
i was criticizing the name of the joiners, not the name of STS.join(). 

Some joiners starts with the prefix "await", some don't, but they all wait, because waiting is something done by the STS implementation, not by the joiner implementation.

I obviously prefer mine :) 
i.e, I think "all" and "await" should not be parts of the name, "await" as discussed above and "all" because the fact that you want all the subtaks whatever their states is a separated concern.

Makes more sense.

You could make a Joiner.Builder class with the following methods.

1. cancelWhen(Predicate<Subtask<T>>)
2. returnValue(R, BiConsumer<R, Subtask<T>>)
3. throwWhen(Predicate<Subtask<T>>)

And the absence of any of the above methods has the following default.

1. Cancel on first Subtask Exception.
2. Return all Subtasks as a List.
3. Throw the first Subtask Exception.

This gives you the power of permutation, while also give you the Pit of
Success. Furthermore, you can do away with all of the static methods.

The only weakness is that you leave performance on the table, in some
cases. Plus, maintaining the Builder gets a little harder, but not by much.

Subject: Problem report on the usage of Structured Concurrency (5th preview)
Message-ID: <85467C61-8139-4832-B3BA-BFA53061E986@warski.org>

Good morning,

with the release of Java 25, I?ve attempted to migrate my virtual-thread-native, reactive-streaming-like library from Java 21 to Java 25 scopes. So far I?ve been using my own wrapper on StructuredConcurrencyScope, but with that migration I wanted to eliminate it, and just use SCS directly. However, I encountered some problems with SCS?s design; I've summarised them in a blog (https://softwaremill.com/critique-of-jep-505-structured-concurrency-fifth-preview), and then prompted by a discussion on Reddit that followed (https://www.reddit.com/r/java/comments/1nq25yr/critique_of_jep_505_structured_concurrency_fifth/), I?m writing here.

Here?s a summary of the issues:

1) SCS works great when tasks are independent, and known upfront; that is, when tasks aren?t dynamically generated based on computations that are part of the scope. In that case, some communication between the forks & the main scope body is needed - typically using queues. The example I give in the article is of a web crawler, however it might not be the best one, as someone on Reddit already pointed out that a better implementation using SCS nested scopes exists. Still, if we add requirements around rate limiting, per-domain connection pooling etc., a solution with a centralised coordinator becomes more viable. Other examples might include implementing an actor-like component, where the actor?s body becomes the scope's body, handles some private (mutable) state, and communicates with child processes (forks created in the scope) using queues.

Such a centralised coordinator (implemented as the scope?s body) does not, however, participate in the error handling contract of the forks. If there?s an exception in the forks, (using the default Joiner) the scope will be cancelled, and all other forks will be interrupted - and that?s of course correct. However, the main scope body won?t be (and it can?t be, as the interruption could escape the scope). If the main scope body includes any blocking logic, it might end up hanging indefinitely, while all the other forks have been cancelled.

To make the problem a little bit more concrete, I encountered the above (and problem number 2 as well) when implementing Jox (https://github.com/softwaremill/jox) `Flow` stages. For example, when merging two streams, the merged substreams need to be run in the background, concurrently, within a concurrency scope. The main scope?s body awaits for data from either of them (on a queue), and when an element is produced, sends it downstream. Now, if we?re not careful with error handling, an exception in one of the substreams will cancel the scope, but the main scope will indefinitely wait on data, not aware of the error.

I?m currently solving this by still having my custom wrapper on top of scopes. The wrapper essentially provides custom concurrency scopes, which run the main scope logic in a fork, making it participate in the error handling/cancellation properties of all other forks. Moreover, I allow creating forks-in-forks, so that the main logic can create forks at will.

2) If the scope?s body does include some non-trivial coordination logic, then it should also be able to decide that a scope is "done". My example here is that there might be two kinds of forks: some implementing the actual logic, and some serving "helper" functions. Following the crawling example, the main-logic forks would be the crawlers; helper forks could e.g. implement monitoring. Now, when the coordinator (main scope body) decides that the computation is done, the scope should be completed, cancelling any helper forks. Currently this can be implemented through a `Joiner`. However, if the data needed to decide, if a scope should complete is present in the coordinator (scope body), it?s problematic to pass that information to the `Joiner`. My work-around here is to create a `Joiner` which monitors an `isDone` flag, and submit an empty task after the work is determined to be done:

void main() throws ExecutionException, InterruptedException {
    var isDone = new AtomicBoolean(false);
    try (var scope = StructuredTaskScope.open(
        new CancellableJoiner<>(isDone))) {
        // some logic

        isDone.set(true);
        scope.fork(() -> {});

        scope.join();
    }
}

class CancellableJoiner<T> 
    implements StructuredTaskScope.Joiner<T, Void> {

    private final AtomicBoolean isDone;
    CancellableJoiner(AtomicBoolean isDone) { this.isDone = isDone; }

    public boolean onFork(
        StructuredTaskScope.Subtask<? extends T> subtask) {
        return isDone.get();
    }

    // ...
}

But it?s more of an ugly trick, rather than a proper solution. I think the essence of the problem is that the logic of the scope is divided between the scope body, and the `Joiner` implementation, and it?s hard to keep them in sync.

3) The final two problems are more of nitpicks. First, a `timeout` method can easily be implemented using the machinery of the SCS, without additional configuration parameters. Special-casing for this seems odd, as timeout is only one example from a family of "resiliency" methods, others including retries, repeats etc. These as well, could be implemented on top of virtual threads and SCS as methods, without special support from the SCS API itself.

4) The Subtask.get() method is confusing, as it has the semantics of Future.resultNow(), but the nomenclature of Future.get(). Since Future.get() is quite well established, I think it?s reasonable to assume, without prior knowledge of the SCS API, that Subtask.get() is blocking as well. However, it works rather differently. I understand that .get() is a fitting name, however given the existing functionalities in place, I would consider changing the name to something without naming or semantical clashes.

----

One might say, that my requirements are above regular use-cases for SCS. However, I view SCS as the new base building block for IO-bound concurrency in Java, and that any future concurrency libraries or projects should use it. This is supported by the fact that `ScopedValue`s are only inherited within SCSs - and I think any concurrency library or feature should provide such propagation. Hence, it should build on top of SCS. That?s why I?m seeking how to make SCS more flexible, to accommodate also for the more unusual or advanced use-cases.

Thank you for your work on SCS and Virtual Threads! I think what?s currently there is really great and powerful, even if not (yet) perfect :).

Regards,
Adam Warski

Of course, it?s StructuredTaskScope, not StructuredConcurrencyScope :) Not sure where I got that from. Sorry for the confusion.

Thanks for writing down your experiences.

(I'll reply to your main points 1 and 2 later as they concern advanced 
use of the API that isn't straight-forward fan-out.)

Just some quick comments on the two smaller points here:


>

If you implement your own Joiner with a side channel to this special 
timeout subtask then it would work. However in general, it will be 
policy (and hence Joiner) dependent as to whether a failing subtask will 
cancel the scope.? You'll see what I mean if you try with it a Joiner 
created by the anySuccessfulResultOrThrow factory method. Same thing 
with any Joiner that has a policy that doesn't unconditionally cancel 
when a subtask fails.

Another point on this topic is that the timeout applies to the scope and 
configuring it when creating the scope is good. Additionally, having 
join throwing TimeoutException is useful to distinguish the timeout case 
from other failure outcomes.

Subtask<T> is a Supplier<T>, and maybe more of the examples should use 
Supplier<T> to avoid anyone thinking Future::get. If someone does 
attempt to use Subtask::get before joining then it will throw of course, 
so they know to use it after join. Ron has long argued that fork should 
just return a Supplier, it's only use is when using subtasks return 
results of different types. If subtasks all return results of the same 
type then the outcome from join is much more useful, no need for 
Supplier::get.

Subject: How do I create a real virtual thread pool?
Message-ID: <CAAMX02oEUZJh=ZB=mm3jPZ93Tozk8D6TDVxU9gGT=nu--1CxzQ@mail.gmail.com>

Hi everyone,

I hope you?re doing well. I have a question about a multi-tenant scenario.
I want to create a dedicated thread pool for each tenant, and these pools
will perform a lot of I/O (for example, database reads and writes). For
this reason I?d like to use virtual threads. However, because virtual
threads share platform threads under the hood, they cannot be fully
isolated from one another.

Consider this situation: a buggy task consumes CPU continuously. If the
host only has a single CPU core, that bug could cause the entire
application to fail. My thought is that if each tenant runs on its own
virtual-thread pool but without sharing platform threads between pools,
platform threads could still time-slice across tenants and thus reduce the
impact of a CPU-burning bug.

For a requirement like this, what would you recommend to achieve better
isolation and robustness? I would appreciate any guidance or suggested
approaches.

Thank you for your time and help.

Best Regards.

Can you say a bit more about the multi-tenancy implementation? Is this a 
fork of the JDK with deep changes to isolate tenants, or is this 
isolation built with module layers or class loaders? If the latter then 
I assume it's an issue for the FJP common pool and all other system-wide 
resources.

So while the JDK doesn't have any support for tenancies, there is 
prototype/experimental support for custom schedulers in the loom repo 
[1]. That could be used to experiment with a having a virtual thread 
scheduler per tenant, or using a system-wide scheduler that dispatches 
the tasks for virtual threads in a tenant to the carriers in that 
tenant. It could be fun to work on. If you do explore this area then 
please come back with any results.

I think i agree with Ron, fork() should return a Supplier with get() failing if not called from the main thread. 

In that case, maybe Subtask.get() should not throw an exception when called from the main thread.

Hi Adam,

First of all, thanks for reaching out with thoughts, comments, and general feedback on your use of Structured Concurrency?it is much appreciated!

Some thoughts and comments below:

>1) SCS works great when tasks are independent, and known upfront; that is, when tasks aren?t dynamically generated based on computations that are part of the scope.

I think I understand what you intend to say, but I think more specifically you're referring to when tasks are generated as a result of *other tasks*, not the scope body itself.

Case in point:

try(var scope = ?) {
while(dynamicCondition) // Dynamic number of tasks
scope.fork(?);
scope.join();
}

>someone on Reddit already pointed out that a better implementation using SCS nested scopes exists.

When in doubt, consider if nested scopes could make the design clearer. This is analoguous to breaking a large, complex, method-body down into multiple smaller ones.

>Still, if we add requirements around rate limiting, per-domain connection pooling etc., a solution with a centralised coordinator becomes more viable.

Not sure how that conclusion was derived. Could you explain further?

>Other examples might include implementing an actor-like component, where the actor?s body becomes the scope's body, handles some private (mutable) state, and communicates with child processes (forks created in the scope) using queues.

Inter-task communication channels are not part of Structure Concurrency at this point in time. It is however important to note that StructuredTaskScope is not the end state of Structured Concurrency.

>If the main scope body includes any blocking logic, it might end up hanging indefinitely, while all the other forks have been cancelled.

That statement is true by definition?any code which is blocking indefinitely and is not interrupted, is by definition blocking indefinitely.

>The main scope?s body awaits for data from either of them (on a queue), and when an element is produced, sends it downstream. Now, if we?re not careful with error handling, an exception in one of the substreams will cancel the scope, but the main scope will indefinitely wait on data, not aware of the error.

This sounds, to me, like another issue with an absent feature?Inter-task communication channels.

>Moreover, I allow creating forks-in-forks, so that the main logic can create forks at will.

As this is described, this means that you could have a race condition between forking in the same scope and the call to scope.join(), or did I misunderstand?

>My work-around here is to create a `Joiner` which monitors an `isDone` flag, and submit an empty task after the work is determined to be done:

Since Joiners are one-shot, and are created before the scope is opened, it would seem more logical(?) to embed that flag into the joiner and have it be set by the scope body by referring to the joiner:

var myJoiner = new MyJoiner(?);
try(var scope = StructuredTaskScope.open(myJoiner)) {
?
myJoiner.signalDone()
scope.join();
}

>But it?s more of an ugly trick, rather than a proper solution. I think the essence of the problem is that the logic of the scope is divided between the scope body, and the `Joiner` implementation, and it?s hard to keep them in sync.

?Designing a Joiner should take into account the code at the use-site where the results from the join method are processed. It should be clear what the Joiner does vs. the application code at the use-site. In general, the Joiner implementation is not the place for "business logic". A Joiner should be designed to be as general purpose as possible.? - https://docs.oracle.com/en/java/javase/25/docs/api/java.base/java/util/concurrent/StructuredTaskScope.Joiner.html

>Special-casing for this seems odd, as timeout is only one example from a family of "resiliency" methods, others including retries, repeats etc. These as well, could be implemented on top of virtual threads and SCS as methods, without special support from the SCS API itself.

While it is true that the I combinator, in SKI calculus, is not primitive because it can be implemented in terms of the S and K combinators, that doesn't necessarily mean that we should strive to distill the absolute primitives. There also exists a scientific paper on the Turing Completeness of the x86 MOV instruction?but it's Turing Completeness does not rule out the value of having specialized instructions.

Putting a deadline on a concurrent operation is established "good practice" to ensure liveness, and the duration for that timeout is most useful if it is provided by the caller, so creating a standardized configuration option for this common operation was deemed to be worth it, since we do not need to either create a scope-within-a-scope by default or filter out the Subtask handling the timeout.

> The Subtask.get() method is confusing

?public static sealed interface StructuredTaskScope.Subtask<T>
extends Supplier<T>? - https://docs.oracle.com/en/java/javase/25/docs/api/java.base/java/util/concurrent/StructuredTaskScope.Subtask.html


All the best!

Cheers,

Subject: Problem report on the usage of Structured Concurrency (5th preview)

Good morning,

with the release of Java 25, I?ve attempted to migrate my virtual-thread-native, reactive-streaming-like library from Java 21 to Java 25 scopes. So far I?ve been using my own wrapper on StructuredConcurrencyScope, but with that migration I wanted to eliminate it, and just use SCS directly. However, I encountered some problems with SCS?s design; I've summarised them in a blog (https://softwaremill.com/critique-of-jep-505-structured-concurrency-fifth-preview), and then prompted by a discussion on Reddit that followed (https://www.reddit.com/r/java/comments/1nq25yr/critique_of_jep_505_structured_concurrency_fifth/), I?m writing here.

Here?s a summary of the issues:

1) SCS works great when tasks are independent, and known upfront; that is, when tasks aren?t dynamically generated based on computations that are part of the scope. In that case, some communication between the forks & the main scope body is needed - typically using queues. The example I give in the article is of a web crawler, however it might not be the best one, as someone on Reddit already pointed out that a better implementation using SCS nested scopes exists. Still, if we add requirements around rate limiting, per-domain connection pooling etc., a solution with a centralised coordinator becomes more viable. Other examples might include implementing an actor-like component, where the actor?s body becomes the scope's body, handles some private (mutable) state, and communicates with child processes (forks created in the scope) using queues.

Such a centralised coordinator (implemented as the scope?s body) does not, however, participate in the error handling contract of the forks. If there?s an exception in the forks, (using the default Joiner) the scope will be cancelled, and all other forks will be interrupted - and that?s of course correct. However, the main scope body won?t be (and it can?t be, as the interruption could escape the scope). If the main scope body includes any blocking logic, it might end up hanging indefinitely, while all the other forks have been cancelled.

To make the problem a little bit more concrete, I encountered the above (and problem number 2 as well) when implementing Jox (https://github.com/softwaremill/jox) `Flow` stages. For example, when merging two streams, the merged substreams need to be run in the background, concurrently, within a concurrency scope. The main scope?s body awaits for data from either of them (on a queue), and when an element is produced, sends it downstream. Now, if we?re not careful with error handling, an exception in one of the substreams will cancel the scope, but the main scope will indefinitely wait on data, not aware of the error.

I?m currently solving this by still having my custom wrapper on top of scopes. The wrapper essentially provides custom concurrency scopes, which run the main scope logic in a fork, making it participate in the error handling/cancellation properties of all other forks. Moreover, I allow creating forks-in-forks, so that the main logic can create forks at will.

2) If the scope?s body does include some non-trivial coordination logic, then it should also be able to decide that a scope is "done". My example here is that there might be two kinds of forks: some implementing the actual logic, and some serving "helper" functions. Following the crawling example, the main-logic forks would be the crawlers; helper forks could e.g. implement monitoring. Now, when the coordinator (main scope body) decides that the computation is done, the scope should be completed, cancelling any helper forks. Currently this can be implemented through a `Joiner`. However, if the data needed to decide, if a scope should complete is present in the coordinator (scope body), it?s problematic to pass that information to the `Joiner`. My work-around here is to create a `Joiner` which monitors an `isDone` flag, and submit an empty task after the work is determined to be done:

void main() throws ExecutionException, InterruptedException {
    var isDone = new AtomicBoolean(false);
    try (var scope = StructuredTaskScope.open(
        new CancellableJoiner<>(isDone))) {
        // some logic

        isDone.set(true);
        scope.fork(() -> {});

        scope.join();
    }
}

class CancellableJoiner<T>
    implements StructuredTaskScope.Joiner<T, Void> {

    private final AtomicBoolean isDone;
    CancellableJoiner(AtomicBoolean isDone) { this.isDone = isDone; }

    public boolean onFork(
        StructuredTaskScope.Subtask<? extends T> subtask) {
        return isDone.get();
    }

    // ...
}

But it?s more of an ugly trick, rather than a proper solution. I think the essence of the problem is that the logic of the scope is divided between the scope body, and the `Joiner` implementation, and it?s hard to keep them in sync.

3) The final two problems are more of nitpicks. First, a `timeout` method can easily be implemented using the machinery of the SCS, without additional configuration parameters. Special-casing for this seems odd, as timeout is only one example from a family of "resiliency" methods, others including retries, repeats etc. These as well, could be implemented on top of virtual threads and SCS as methods, without special support from the SCS API itself.

4) The Subtask.get() method is confusing, as it has the semantics of Future.resultNow(), but the nomenclature of Future.get(). Since Future.get() is quite well established, I think it?s reasonable to assume, without prior knowledge of the SCS API, that Subtask.get() is blocking as well. However, it works rather differently. I understand that .get() is a fitting name, however given the existing functionalities in place, I would consider changing the name to something without naming or semantical clashes.

----

One might say, that my requirements are above regular use-cases for SCS. However, I view SCS as the new base building block for IO-bound concurrency in Java, and that any future concurrency libraries or projects should use it. This is supported by the fact that `ScopedValue`s are only inherited within SCSs - and I think any concurrency library or feature should provide such propagation. Hence, it should build on top of SCS. That?s why I?m seeking how to make SCS more flexible, to accommodate also for the more unusual or advanced use-cases.

Thank you for your work on SCS and Virtual Threads! I think what?s currently there is really great and powerful, even if not (yet) perfect :).

Adam Warski

Hi Alan?

Thanks for your reply. I haven?t implemented this yet; it was just an idea
I raised for discussion.

Thanks for pointing me to the CustomSchedulers feature ? I think it could
help isolate platform threads in a multi?tenant environment while still
letting us benefit from virtual threads.

I?ll give it a try. Thanks again. By the way, do you know whether this
feature is already available in JDK 25?

Best Regards.

No plan right now to propose this feature for the JDK. The prototype in 
the loom repo is to allow for experimentation to see if there are 
compelling use-cases and results that would justify going further in the 
one of the directions in the prototype.

Maybe a page can be taken from JS Promise static methods [1]:

* Joiner.all() instead of Joiner.allSuccessfulOrThrow()
* Joiner.allSettled() instead of Joiner.awaitAll()
* Joiner.any() instead of Joiner.anySuccessfulResultOrThrow()
* Joiner.until(..) instead of Joiner.allUntil(..) [not part of the JS
Promise static functions, but seemed like a logical extension to the naming
pattern]

As a side note, perhaps having Joiner.allSettled() return the subtasks
themselves (in a stream?), and you can interrogate each one for
success/failure, rather than having to manually keep track of subtasks for
later use.

It seems like there's an opportunity to further constrain the usage of Subtask::get to avoid race conditions.

The reason we didn't include a Joiner for that is because it is 
trivially done with Joiner.allUntil(_ -> false).? Also, the main case 
where you have to keep a reference to the subtasks is when they return 
results of different types. If they all return a result of the same type 
then you can use the return from join.

I agree, this example would be a good fit for channels.

On interrupting the main task ("Non-uniform cancellation" section in the 
article), it's a good topic to discuss. When the scope is cancelled then 
the outstanding subtasks are interrupted so that they finish up quickly 
(their results aren't needed). It would mostly wrong to interrupt the 
main task as you aren't looking for the main task to finish, instead you 
want the main task to wakeup (from join) to process the outcome. It's 
important to say that cancellation does not mean failure, it just means 
there is an outcome, e.g. anyResultOrThrow cancels after any subtask 
completes successfully. A lengthy/looping forking phase can use 
isCancelled to avoid doing unnecessary work if needed. (Early prototypes 
did interrupt the main task but this was problematic on many levels and 
adds booking overhead to ensure that the processing of that interrupt is 
restricted to code in the block.)

Yes. A sensible analogy to STS cancellation is "short-circuiting" in the Stream operations sense. It means that there's a valid result before all tasks have completed.

That statement is true by definition?any code which is blocking indefinitely and is not interrupted, is by definition blocking indefinitely.

>The main scope?s body awaits for data from either of them (on a queue), and when an element is produced, sends it downstream. Now, if we?re not careful with error handling, an exception in one of the substreams will cancel the scope, but the main scope will indefinitely wait on data, not aware of the error.

This sounds, to me, like another issue with an absent feature?Inter-task communication channels.

Message-ID: <1920101532.708894.1758908500414.JavaMail.zimbra@univ-eiffel.fr>

Currently,
the interface Subtask defines 3 different states, but while the implementation needs 3 states, I believe the interface only need 2.

Currently, having 3 states punished people that are using the API correctly, i.e accessing the state when all the computations are done,
after join() is called, because for them, only two states are visible, but they still need to write a code that takes can of the state
UNINITIALIZED.

I propose that state() can only return SUCCESS or FAILURE and throw an ISE if the internal state is UNINITIALIZED given it means
that the API is not used correctly.

In the past, with the previous iteration of the design using inheritance instead of delegation, the Subtask was not sealed,
so the internal state had to be exposed, but now that only the implementation of STS can create a Subtask, the internal state UNINITIALIZED does not have to be visible.

Subtask has always been sealed. It has always had 3 states, nothing has 
changed, and nothing from the implementation has leaked into the API. So 
I'm a bit puzzled by your message. There is no outcome to report when a 
subtask is executing, was cancelled, or was forked after the scope was 
cancelled. The Subtask::state returns "UNAVAILABLE" for all these cases. 
It's easy to come up with examples where join returns a stream of 
subtasks in each of these states.

Is your gripe with the onComplete method when writing a custom Joiner? 
That will only be called when the Subtask has completed and so is 
guaranteed to be in the SUCCESS or FAILED state?

sorry, 
i forget that case, worst, i think you already explain that to me, again sorry.

yes, 
i think my mistake comes from the fact that for me the subtasks returned by STS.join() should all have been gone through onComplete, 
but this is not the case actually

I?ll try to clarify those together.

So first of all yes, you?re right, the problematic scenario isn?t dynamic task creation in general, but a subset, where tasks are generated as results of other tasks. And yes, if there are equivalent solutions using nested scopes or a centralised coordinator, then going with the less-centralized option, and leveraging nested scopes is definitely the way to go. I won?t contend anything here :). But - the scenarios I?m referring to are when nested scopes either aren?t possible to use (because of the nature of the problem), or would complicate the overall code.

Continuing the example of the crawler. A reasonable requirement is to add a per-domain limit on how many connections can be opened to a given domain at any time, plus a global limit on connections. One way to implement this on top of STS is to use nested scopes, as pointed out on reddit (https://www.reddit.com/r/java/comments/1nq25yr/comment/ng3yk7b/). However, to maintain the limits, you?d then need a ConcurrentHashMap mapping domains to per-domain Semaphores, plus a global Semaphore to enforce the global limit. And now this becomes tricky to implement correctly: which semaphore do you acquire first? What if there?s a concurrent update to the map? You?ll need to use CAS and the like to ensure correctness of the process. Doable, but not necessarily the cleanest solution.

I suppose the point here is that when using nested scopes, for problems where some communication between the processes needs to happen, you have to rely on shared (mutable) memory, and use synchronization tools such as concurrent maps, semaphores etc.

An alternative (one which I think you?ve exercised to the extreme ;) ) is to use something more like an actor: a centralised process-coordinator which manages the whole computation. We can still use STS, but instead of a tree of scopes, we flatten this to a single scope, which creates crawler-forks in accordance with the various rate-limiting restrictions. The logic in the coordinator is definitely non-trivial, but it?s now single-threaded and we don?t have to worry about atomic updates and the like. But, we still need to communicate somehow with the child processes, and that?s where queues or channels come in.

(And using STS might not be just a whim, we might **have to** to use it, as we might need ScopedValues propagation, or we want the guarantee, that no thread leaks are possible)

Of course, the crawler is just one example, with which I hope to illustrate a point: that there?s a class of problems where some coordination between forks is crucial, and while some of these can be solved using shared memory and java.util.concurrent, it?s not always the best approach. I understand that inter-task communication is out of scope of the JEP, but since we are designing the future of Java?s IO-bound concurrency (or at least, that?s my perception of the goal of the JEP), it would be good to at least know that STS is extendible so that it might accommodate to these requirements in the future. Or integrate with third-party solutions. I?m quite sure people will end up just using LinkedBlockingQueues (or something like Jox?s Channels, which are completable & error-aware) as soon as the JEP becomes final.

So now to the crux of the problem: using blocking operations in forks has different error handling than using blocking operations in the body of the scope. The first will be interrupted when there?s an exception in any of the forks (under the default Joiner). The second will not - it will just hang. I think it does put a dent in the otherwise "let it crash" philosophy that you might employ when working with STS. That is, when an exception occurs, you can be sure that everything will be cleaned up properly, and the exception is propagated. With a caveat: only when the scope?s main body is blocked on scope.join(), not some other operation.

> >Moreover, I allow creating forks-in-forks, so that the main logic can create forks at will.

Well if scope.join() waits until all forks complete, it will only do so when there are no forks left, and then nobody can create new forks? So I don?t think there?s a race here? In other words, forks can only be created from live forks, before they complete.

Yes, sure, the design here can be cleaner. But I still think the idea of using an AtomicBoolean to signal completion smells like a work-around, not a "proper" way to use Joiners. But maybe I?m too picky?

Sure, and we might not want to represent numbers in terms of tuples and units :). As I said, it?s more a nitpick, but for me a timeout(Duration, Runnable) method seems more general and light-weight. That said, I?m not too worried about nested scopes, as they seem really light-weight, but maybe the current solution has potential for more optimization.

Ah, you see, I didn?t even notice the Supplier there. I?d still argue, though, that when people see a Subtask<T>, they would rather think of it in terms of analogies with a Future<T> ("a computation for which a result will be available in the future"), rather than a supplier. Especially that Subtask.get() can only be called under specific circumstances - after scope.join() has completed. So I?m not sure if the contract of Supplier even fits here? But maybe I?m too biased by working with Future-like things for a longer time.

Thank you for the answers!

Yes, sure, the design here can be cleaner. But I still think the idea of using an AtomicBoolean to signal completion smells like a work-around, not a "proper" way to use Joiners. But maybe I?m too picky?

Sure, and we might not want to represent numbers in terms of tuples and units :). As I said, it?s more a nitpick, but for me a timeout(Duration, Runnable) method seems more general and light-weight. That said, I?m not too worried about nested scopes, as they seem really light-weight, but maybe the current solution has potential for more optimization.

Ah, you see, I didn?t even notice the Supplier there. I?d still argue, though, that when people see a Subtask<T>, they would rather think of it in terms of analogies with a Future<T> ("a computation for which a result will be available in the future"), rather than a supplier. Especially that Subtask.get() can only be called under specific circumstances - after scope.join() has completed. So I?m not sure if the contract of Supplier even fits here? But maybe I?m too biased by working with Future-like things for a longer time.

Thank you for the answers!

When the scope is cancelled then the outstanding subtasks are interrupted so that they finish up quickly (their results aren't needed). It would mostly wrong to interrupt the main task as you aren't looking for the main task to finish, instead you want the main task to wakeup (from join) to process the outcome. It's important to say that cancellation does not mean failure, it just means there is an outcome, e.g. anyResultOrThrow cancels after any subtask completes successfully. A lengthy/looping forking phase can use isCancelled to avoid doing unnecessary work if needed. (Early prototypes did interrupt the main task but this was problematic on many levels and adds booking overhead to ensure that the processing of that interrupt is restricted to code in the block.)

Yes, I think that interrupting the main task in fact cannot be implemented properly, for the reasons you describe (an interruption b/c of scope cleanup is indistinguishable from an interruption coming externally). But you definitely have a point that cancellation is a result, not necessarily failure. On the other hand, there are "unexpected" exceptions (something along the original distinction between checked/unchecked exceptions), which *are* a failure, and when I think it?d be ideal if we could clean up the whole scope (ensuring that no threads stay alive), and re-throw for further handling. This distinction ("fatal"/"non-fatal" or "failulre" / "result") would logically belong to the Joiner, I suppose?

Using the isCancelled flag as part of the scope?s body is an interesting idea, but then any blocking operations (such as retrieving an element from a queue) would need a timeout? And when the timeout passes, we?d check the flag?

Hi Adam,

Responses inline below:


> where tasks are generated as results of other tasks.

Yes, and this is only an "issue" if you want those tasks to be siblings to the tasks whose result yielded their existence. (Nesting a new scope in task is still possible)

>Continuing the example of the crawler. A reasonable requirement is to add a per-domain limit on how many connections can be opened to a given domain at any time, plus a global limit on connections.

The question whose responsibility defending those boundaries?one could (equally successfully) argue that total limits and per-domain limits could be ensured by the logic which performs the outbound calls (similar to how connection pools for databases enforce a total limit of outbound database connections.)

>I suppose the point here is that when using nested scopes, for problems where some communication between the processes needs to happen, you have to rely on shared (mutable) memory, and use synchronization tools such as concurrent maps, semaphores etc.

The challenge is (mainly) when you need bidirectional communication, possibly even with a dynamic number of participants, or as a part of a larger orchestration of communication between participants. With that said, it's a much larger topic than an email would do justice.

>An alternative (one which I think you?ve exercised to the extreme ;) ) is to use something more like an actor: a centralised process-coordinator which manages the whole computation.

Heh, I might have a smidge of experience in that department, yes. ;)

>We can still use STS, but instead of a tree of scopes, we flatten this to a single scope, which creates crawler-forks in accordance with the various rate-limiting restrictions. The logic in the coordinator is definitely non-trivial, but it?s now single-threaded and we don?t have to worry about atomic updates and the like. But, we still need to communicate somehow with the child processes, and that?s where queues or channels come in.

From my perspective, there's no obvious advantage to "flattening the tree"?the risk is that you're embedding a lot more complexity into a single place, leading to hard to diagnose issues, and a rather high barrier to entry.

>So now to the crux of the problem: using blocking operations in forks has different error handling than using blocking operations in the body of the scope. The first will be interrupted when there?s an exception in any of the forks (under the default Joiner). The second will not - it will just hang. I think it does put a dent in the otherwise "let it crash" philosophy that you might employ when working with STS. That is, when an exception occurs, you can be sure that everything will be cleaned up properly, and the exception is propagated. With a caveat: only when the scope?s main body is blocked on scope.join(), not some other operation.

I understand what you're saying, yet what I hear that you're proposing is merely moving the target one step further. ?Quis custodiet ipsos custodes? ? even if the main block were to be "lifted" into a Virtual Thread and be "symmetric" or equivalent in its behavior as compared to its tasks, the code which creates the block would not, and so now you've "only" managed to move the sameness in behavior a step further, and now you have a dissimilarity between that and the "coordinator" and the cycle repeats.

>Well if scope.join() waits until all forks complete, it will only do so when there are no forks left, and then nobody can create new forks? So I don?t think there?s a race here? In other words, forks can only be created from live forks, before they complete.

I believe I misunderstood, thanks for clarifying, Adam. So you're saying you're scope.fork():ing concurrently to scope.join(), and the "benefit" to that is that the body of the scope can perform other responsibilities because it has outsourced the forking?

>Yes, sure, the design here can be cleaner. But I still think the idea of using an AtomicBoolean to signal completion smells like a work-around, not a "proper" way to use Joiners. But maybe I?m too picky?

In my Joiner example there'd be no need to expose the AtomicBoolean, so it would be an internal implementation detail to the Joiner in question. It is definitely within the area of responsibilities for a Joiner to decide when the scope is "done".

>Sure, and we might not want to represent numbers in terms of tuples and units :). As I said, it?s more a nitpick, but for me a timeout(Duration, Runnable) method seems more general and light-weight. That said, I?m not too worried about nested scopes, as they seem really light-weight, but maybe the current solution has potential for more optimization.

As a side-note: An interesting, recent, development is that ForkJoinPool now implements ScheduledExecutorService.

>Ah, you see, I didn?t even notice the Supplier there. I?d still argue, though, that when people see a Subtask<T>, they would rather think of it in terms of analogies with a Future<T> ("a computation for which a result will be available in the future"), rather than a supplier.

But maybe I?m too biased by working with Future-like things for a longer time.

As I have dabbled with Futures a little bit, I can absolutely see why one'd think it is related to Future, and in this case I think it is important to judge things based on what they claim that they are (Subtask is not a Future) rather than what one believes them to be (Future). Just like Optional.get() wouldn't want to have to live up to the expectations of Future.get() :)

You're most welcome!

I?ll try to clarify those together.

So first of all yes, you?re right, the problematic scenario isn?t dynamic task creation in general, but a subset, where tasks are generated as results of other tasks. And yes, if there are equivalent solutions using nested scopes or a centralised coordinator, then going with the less-centralized option, and leveraging nested scopes is definitely the way to go. I won?t contend anything here :). But - the scenarios I?m referring to are when nested scopes either aren?t possible to use (because of the nature of the problem), or would complicate the overall code.

Continuing the example of the crawler. A reasonable requirement is to add a per-domain limit on how many connections can be opened to a given domain at any time, plus a global limit on connections. One way to implement this on top of STS is to use nested scopes, as pointed out on reddit (https://urldefense.com/v3/__https://www.reddit.com/r/java/comments/1nq25yr/comment/ng3yk7b/__;!!ACWV5N9M2RV99hQ!L9F3IT3OW3MJ1Tw3IwbQL99I7_CqQJGWxghNCf8IGjLR6TNVCjae_D1Ih2AHPHSsCrOKebwR9qucoOM$ ). However, to maintain the limits, you?d then need a ConcurrentHashMap mapping domains to per-domain Semaphores, plus a global Semaphore to enforce the global limit. And now this becomes tricky to implement correctly: which semaphore do you acquire first? What if there?s a concurrent update to the map? You?ll need to use CAS and the like to ensure correctness of the process. Doable, but not necessarily the cleanest solution.

I suppose the point here is that when using nested scopes, for problems where some communication between the processes needs to happen, you have to rely on shared (mutable) memory, and use synchronization tools such as concurrent maps, semaphores etc.

An alternative (one which I think you?ve exercised to the extreme ;) ) is to use something more like an actor: a centralised process-coordinator which manages the whole computation. We can still use STS, but instead of a tree of scopes, we flatten this to a single scope, which creates crawler-forks in accordance with the various rate-limiting restrictions. The logic in the coordinator is definitely non-trivial, but it?s now single-threaded and we don?t have to worry about atomic updates and the like. But, we still need to communicate somehow with the child processes, and that?s where queues or channels come in.

(And using STS might not be just a whim, we might **have to** to use it, as we might need ScopedValues propagation, or we want the guarantee, that no thread leaks are possible)

Of course, the crawler is just one example, with which I hope to illustrate a point: that there?s a class of problems where some coordination between forks is crucial, and while some of these can be solved using shared memory and java.util.concurrent, it?s not always the best approach. I understand that inter-task communication is out of scope of the JEP, but since we are designing the future of Java?s IO-bound concurrency (or at least, that?s my perception of the goal of the JEP), it would be good to at least know that STS is extendible so that it might accommodate to these requirements in the future. Or integrate with third-party solutions. I?m quite sure people will end up just using LinkedBlockingQueues (or something like Jox?s Channels, which are completable & error-aware) as soon as the JEP becomes final.

So now to the crux of the problem: using blocking operations in forks has different error handling than using blocking operations in the body of the scope. The first will be interrupted when there?s an exception in any of the forks (under the default Joiner). The second will not - it will just hang. I think it does put a dent in the otherwise "let it crash" philosophy that you might employ when working with STS. That is, when an exception occurs, you can be sure that everything will be cleaned up properly, and the exception is propagated. With a caveat: only when the scope?s main body is blocked on scope.join(), not some other operation.

> >Moreover, I allow creating forks-in-forks, so that the main logic can create forks at will.
>
> As this is described, this means that you could have a race condition between forking in the same scope and the call to scope.join(), or did I misunderstand?

Well if scope.join() waits until all forks complete, it will only do so when there are no forks left, and then nobody can create new forks? So I don?t think there?s a race here? In other words, forks can only be created from live forks, before they complete.

I encourage everyone to reread the original JEP on structured concurrency - a simple and effective solution for a common problem. 

I read many of these comments and I shudder to think of how complex their codebases must be - and so instead they are trying to change STS to fit their messes rather than fix their messes.

And yes, if there are equivalent solutions using nested scopes or a centralised coordinator, then going with the less-centralized option, and leveraging nested scopes is definitely the way to go. I won?t contend anything here :). But - the scenarios I?m referring to are when nested scopes either aren?t possible to use (because of the nature of the problem), or would complicate the overall code.

One way to implement this on top of STS is to use nested scopes, as pointed out on reddit (https://urldefense.com/v3/__https://www.reddit.com/r/java/comments/1nq25yr/comment/ng3yk7b/__;!!ACWV5N9M2RV99hQ!L9F3IT3OW3MJ1Tw3IwbQL99I7_CqQJGWxghNCf8IGjLR6TNVCjae_D1Ih2AHPHSsCrOKebwR9qucoOM$ ). However, to maintain the limits, you?d then need a ConcurrentHashMap mapping domains to per-domain Semaphores, plus a global Semaphore to enforce the global limit. And now this becomes tricky to implement correctly: which semaphore do you acquire first? What if there?s a concurrent update to the map? You?ll need to use CAS and the like to ensure correctness of the process. Doable, but not necessarily the cleanest solution.

We can still use STS, but instead of a tree of scopes, we flatten this to a single scope, which creates crawler-forks in accordance with the various rate-limiting restrictions. The logic in the coordinator is definitely non-trivial, but it?s now single-threaded and we don?t have to worry about atomic updates and the like. But, we still need to communicate somehow with the child processes, and that?s where queues or channels come in.

I understand that inter-task communication is out of scope of the JEP, but since we are designing the future of Java?s IO-bound concurrency (or at least, that?s my perception of the goal of the JEP), it would be good to at least know that STS is extendible so that it might accommodate to these requirements in the future. Or integrate with third-party solutions. I?m quite sure people will end up just using LinkedBlockingQueues (or something like Jox?s Channels, which are completable & error-aware) as soon as the JEP becomes final.

As I said, it?s more a nitpick, but for me a timeout(Duration, Runnable) method seems more general and light-weight. That said, I?m not too worried about nested scopes, as they seem really light-weight, but maybe the current solution has potential for more optimization.

Yes, there?s multiple ways to implement this, each with their tradeoffs. I?m not saying that shared memory / connection pool are bad in all cases, just that an actor-like / central "coordinator" should also be possible, when using STS. With the same error handling properties, as the concurrency scopes generally offer.

Not quite: it depends where this "complex" or "correct" code has to be implemented - is it by the user, or offered by a library? Quite often the value proposition of libraries is to hide some ugly implementation details and offer a nice abstraction for the user. If the "lifting" of the main block onto a VT is done by the library, we can implement this once (correctly, with appropriate testing etc.), and then only expose to the users the "safe" variant. That is, users would be able to define the code that runs in the "main block", but not in the orchestrator.

> 
> I believe I misunderstood, thanks for clarifying, Adam. So you're saying you're scope.fork():ing concurrently to scope.join(), and the "benefit" to that is that the body of the scope can perform other responsibilities because it has outsourced the forking?

If we allow forks-from-forks, then we can keep the main-scope logic dead simple, with just a couple of scope.fork, followed by a scope.join.
All the complex coordination logic might then go into a "main" fork. Such "main" fork might then start further forks, fully participating in the error handling / cancellation protocol, just as all other forks. 

Not sure if it?s the best idea, it?s just an idea ;)

Yes, sure. But then submitting an empty task, just to let the joiner "discover" that the flag has changed, and so that it might return false from onFork - well to me this look suspicious.

Just like Optional.get() wouldn't want to have to live up to the expectations of Future.get() :)

Well, it?s in the name of the class ;). `Option` (or `Supplier`) doesn?t suggest anything related to concurrency. So no - I?m not saying that `.get()` is now forever doomed to only mean "block this thread until a result is available". Also, `Option` is an inspectable data structure, unlike futures etc.
`Subtask` is simply a name which (at least to me) is immediately associated with a `Future`. But again, that?s more of a nitpick, then any fundamental problem.

Well my understanding (which might be wrong) is that the JEP has ambitions higher than implementing `par` and `race`, and that the parallel-run example is just this: a simple example that demonstrates the usage of a general API coming to Java.

As for complexity: as long as it's essential, not accidental, we can only look for better abstractions that make it bareable :)

     It is not a goal to create the definitive structured concurrency 
API for all Java programs. Other structured concurrency constructs can 
be defined by third-party libraries or in future JDK releases.

...so I have to differ from your view that "any future concurrency 
libraries or projects should use [StructuredtaskScope]."

But I take your point about ScopedValue. It is possible that if we can 
find a secure way to manage the lifetime of scoped values in subtasks, 
we will do it. This is something we're thinking about.

That's right but allowing this (as it was in early previews) creates 
weirdness where a subtask can fork it cannot join. It also messes with 
the mental model of "parent".? Who is my parent when I'm forked by a 
sibling?

If the problem has been arranged so that subtask opens a new scope and 
decomposes into a set of sub-subtasks forked in this scope, thus 
creating a hierarchy, then it becomes simpler to reason about.
