I think I understand that point.

However, scoped values restrict what is possible, by design. A
(conditional) goto is more powerful than any other control structure,
but we don't support gotos in Java because they make it hard to reason
about programs. Instead we use much more limited control structures.

Like function arguments, scoped values pass from caller to callee. I'm
very open to talking about ways to make scoped values more useful. We
figured out how to use StructuredTaskScope to share scoped values
between threads in a way that doesn't compromise any
guarantees. However, any structure that allows a scoped value to live
after its binding scope has terminated is out of the question because
it breaks a fundamental invariant.

> ... we don't support gotos in Java ...

I don't think goto is a good comparison, because goto doesn't need to
be supported, since - even for cases when it would be useful - it is
trivial to workaround. However, the problem I wrote down is different,
because the current constructs prevent any solution.

Let me rephrase the problem: Consider that a hypothetical (simplistic)
SV based DI framework supports lazily created singleton resources (and
it will close them, if they were actually created). For example (with
my originally described micro API):

```
/* 01 */ ScopedValue<String> testValue = ScopedValue.newInstance();
/* 02 */
/* 03 */ ScopedValue.where(testValue, "OuterValue", () -> {
/* 04 */   withBinding(MyResource.class, this::getLazyMyResource, () -> {
/* 05 */     ScopedValue.where(testValue, "InnerValue", () -> {
/* 06 */       System.out.println("1: " + getByType(MyResource.class));
/* 07 */     });
/* 08 */     System.out.println("2: " + getByType(MyResource.class));
/* 09 */   });
/* 10 */ });
```

In line (4), the application knows that we are in a well-defined
context (by its nature, there is exactly one point where you are
binding the factory `MyResources`). However, you don't know where it
will be queried (if it is at all), and especially don't know where it
will be queried the first time (you would not use a lazy construct
otherwise). That said, a reasonable DI framework wants to define a
consistent well-defined behaviour. However, as it stands now, it is
impossible, because it cannot guarantee a consistent context for the
`getLazyMyResource` call. For example, if I added a
`getByType(MyResource.class)` call between (4) and (5), then that
would change the behaviour of the code, if the resource depends on the
value of `testValue`. This would be a completely unacceptable
behaviour, and - as far as I know - there is no way to workaround
this. That is, the current limitations on SV scope handling disallow
APIs from exhibiting consistent behaviour, if they don't want to know
the context where their own SV is being access from. (there are even
more limitations of SV, but first I wanted to focus on this issue,
since this is the simplest case)

I do not want this at all, and never suggested to have this
possibility. In fact, I agree that such access should not be allowed.

I'm sorry, trying to understand what you want is exhausting.

Please provide a concise and precise definition of what your API to
capture current scoped values would do. I do not need any examples
of how it might be used, just an operational definition of the
CapturedScopedValueContext API.

With respect, I don't think you should approach the problem this way. If
you have a DI framework which uses scoped values to determine what is
bound, I think you'd be *much* better off binding a small number of
contexts which are defined by the DI framework than you would be by binding
everything that is available (which could be hundreds? thousands? ten
thousands? of bound objects in real-world situations). You can very easily
implement whatever functionality you want by wrapping the ScopedValue API
without compromising the design principles of that API, rather than trying
to make the ScopedValue API do something it is not intended for.

I for one do not *ever* want any external framework to be able to re-bind
context objects that I define without going through APIs that I control,
under any circumstances. Encapsulation is a feature not a bug.

I would not want to do many bindings (only exactly 1 under normal
circumstances), but for the sake of this example, I did not want to
complicate it with issues irrelevant to the problem. Anyway, I don't
see how "wrapping the ScopedValue API" would solve my issue, because
my issue is that I cannot make this framework capture the current
bindings of scoped values and use them in a nested scope. Anyway - for
Andrew's request - I will soonish write an example API that the JDK
could provide to solve my problem (alongside with some exact
specification of what methods would do there). I hope that will
clarify my intent.

To be honest I don't understand what you are referring to here. I
would not intend to directly expose the SV to the client of the DI
framework.

Let's assume we have a static method like this in `ScopedValue`:

```
public static void withCapturedContext(
    Consumer<? super CapturedScopedValueContext> task
) { ... }
```

where `CapturedScopedValueContext` is defined this way:

```
public interface CapturedScopedValueContext {
  <T> T inContext(Callable<? extends T> task);
}
```

The method `withCapturedContext` captures the current scoped value
bindings, then immediately calls its argument (task) with an instance of
`CapturedScopedValueContex` which will run tasks with the captured scope
value bindings (when calling its `inContext` method). However,
`CapturedScopedValueContext.inContext` validates if the captured scope
value bindings is the same as the current one, or the parent of the current
scoped value bindings, and if it is not, then fails with an ISE.

That is, this could be an unoptimized implementation of
`withCapturedContext` (with the only caveat that currently `runWith`
doesn't have a static variant):

```
public static void withCapturedContext(
    Consumer<? super CapturedScopedValueContext> task
) {
  var capturedBindings = scopedValueBindings();
  task.accept(new CapturedScopedValueContext() {
    @Override
    public <T> T inContext(
        Callable<? extends T> inContextTask
    ) {
      scopedValueBindings().verifyValidContext(capturedBindings);
      return runWith(capturedBindings, inContextTask);
    }
  });
}

static final class Snapshot {
    // ...

    void verifyValidContext(Snapshot checked) {
        for (var current = this; current != null; current = current.prev) {
            if (current == checked) {
                return;
            }
        }
        throw new IllegalStateException("Invalid context.");
    }
}
```

I hope this clarifies what functionality I'm missing.

What would happen if there was some context which is implemented in some
way *other* than ScopedValue? For example, using thread locals, or a field
on Thread, or something like that?

I understand your implication that I'm being a little bit hypocritical by
concerning myself with SV, but not with others. And of course that is
unfortunate, and I can't do anything about it. But the reason I care more
about the SV scope than others is because I see scope to be more important,
because this looks to me as a promising emerging concept. That is, we could
have a future, where SVs are promoted properly everywhere (for example,
StructuredTaskScope propagates it to the child tasks), What I mean by
"promoted properly" is that at some point (there are various missing tools
for that still) we could have what I would call a "properly scoped"
application, where opening a new scope in `main`, whatever I set there will
be visible to all application code, and if started so (there could be an
implicit virtual scope for `main` as well), then the whole application
would sit in a scope tree (even with concurrency considered) which would
allow me to reason correctness about my code better. In such a world, a DI
framework like I mentioned could be useful (and I believe a lot of
other future APIs could benefit from proper scoping).

What I for one do *not* want is for someone other than myself to decide
what "properly scoped" means for a given piece of code that I write, nor do
I want behavior outside what is strictly required for implementing locally
scoped variables.

Let me give a real-world example of why this is a problem. We have a
security identity framework where our identities are associated in the
manner of ScopedValue. A user may query what identity is currently active,
and the user may execute some block of code with a new active identity.
However, we found early on that some existing frameworks - like the Servlet
specification for example - do not allow us to interpose a call like
identity.runAs(() -> { ... }) in the midst of handling a request, for right
or for wrong. So instead what we offer is a way to lexically scope a
"flexible identity association". The identity may be changed within the
scope of an operation, but the flexible association does not escape the
bounds of the lexical scope that it was run under.

Why is this a problem? If you have some means to capture - even just for
the purposes of verification - the "scope" as defined by all active
ScopedValues, your expectation may be that you have captured the active
identity that was present at the time of the capture. However this would
not be the case in practice, and so you'd have a wrong "answer". In other
words, the semantic meaning of what I store in an in-scope scoped value
association has a bearing on what it means to capture it, and that semantic
meaning is nobody's business but my own. Therefore, any API which broadly
captures all scoped values for *any* reason is also semantically
meaningless and therefore misleading at best, and disastrous at worst
(think CVEs).

If I control a scoped value, then I want nobody to have access to it for
any reason at any time without my explicit mediation and permission. I
think this is critical to the design, and I think that trying to impose a
greater framework on what is essentially a mechanism for locally-scoped
variables would be a mistake, and I further believe that this mistake could
result in vulnerability to exploitation. Given that any locally-scoped
variable mechanism may be used to implement any other locally-scoped
variable mechanism, my opinion is that if you want locally-scoped variables
which carry some additional meaning or behavioral constraints above those
established by ScopedValue, you can implement one yourself (see Jakarta
Context Propagation for example). ScopedValue, being the new foundational
means to achieve local scoping, would not be the correct place to do this
since any assumptions or behaviors implicit in its usage would inescapably
creep into that of everything derived from it. Which I guess you view as a
feature but I view as a potential disaster.

I meant very little by "properly scoped", only that scopes organize into a
single tree (assuming an implicit scope for `main`), and all code runs in a
scope. You are still in complete control of how to create scope, and what
scope to use.

In my DI framework example (of course it doesn't have to be a DI framework,
the point is the lazy factory), you are currently having a different
security issue. That is, at top level I bound the factory, and then lazily
somewhere down (possibly in an authenticated scope) you could be running
(unknowingly) the factory with credentials, and that is most certainly not
something you want.

As for your concern: You are already screwed :) In fact, I have realized
that I have a (horrible) way to implement what I want with
`StructuredTaskScope`, because when I'm binding the factory in my example,
I can open a new STS, fork a task immediately which will just stop and wait
and when down the line the "resource" is requested, I will just let the
task go, and channel back the result. Actually, I'm very glad you are
making these criticisms, because it made me realize a better way to imagine
what I want (functionality wise it would be the same). That is, my
`CapturedScopedValueContext.inContext` method should be imagined as running
a task in parallel, but the parallel task is being executed in a higher
level scope. So, even if nothing else comes out of it, I'm already glad to
have written this, and that you responded :)

To prove my point below, I have created very simplistic POC (ignore the
fact that it is full of poor exception handling please, and of course is
intentionally overly simplistic) that can do what I want (written in Java
20): <https://gist.github.com/kelemen/5a334e3d189f91355c4615ad94d0b6fd>

The entry point is InjectorTest, and it now properly prints "OuterValue".
So, I would slightly change my request to provide a more reasonable
implementation of my `CapturedScopes.withCurrentContext` without my
horrible abuse of STS.

Note: Ignore that I'm using my own utility `TerminableQueue`, which is just
basically a closeable channel.

I don't understand this problem. What is this code that incorrectly rebound
the factory to some inappropriate value? Why does this code have this
power? There is an intuition here about DI frameworks that I also don't
understand: that factory clients don't want the new-like operation to react
to the actually current context, but must react to some
previously-current-at-that-time context. Is this really how standard DI
works? I would expect that, if my application updates the current context
somehow, and then calls into a new-like operation, this call must be affect
by the changes I just applied.

Standard DI frameworks do not need to concern themselves with this since
they do not even know about SV. However, in some abstract sense they do
work this way (at least some do). For example, you can organize Spring's
`ApplicationContext` instances into a tree. In which case a bean in the
parent `ApplicationContext` will not see the beans in a child
`ApplicationContext`. However, note that an SV based DI framework would use
the SV bindings as its "ApplicationContext" (`ScopedValue.Snapshot`
essentially). So, for such a framework it is an essential feature (if you
want parent child relationships, which you often need).

As for "this call must be affected by the changes I just applied": This
depends on what exactly we are talking about. For non-singleton objects, it
might be the case (though usually I don't think so, because normally in a
DI framework an injected object should depend on other objects managed by
the DI framework), but for lazy singletons, it is definitely not something
you want, because the context where the singleton would be created would be
ill-defined (i.e., first use, which would be horribly fragile).

But this is a cross thread relationship, right? The scoping in this case is
transversal to lexical scoping or thread scoping. A bean that is bound to
some sub-context of the application context, is bound during a time that is
defined by the application life cycle, not by some call chain active in
some thread. Why would one implement all this inside ScopedValue?

The way I imagine, is that in the future you could design an application
around scopes (in the abstract, SV is just a visible thing in the scope).
That is, all your application is a single tree of scopes, and all the
application code is within a scope. In this world, scopes would be a
natural candidate to be used as DI contexts, because scopes have a well
defined life-cycle, and that would make arguing about the lifetime and
ownership (and who can have access to them) of resources easy. To me at
least it is always a big pain point that it is hard to prove that a
resource that has a given lifetime is not used outside its lifetime, and
also that I can limit its life to a minimum. And since scopes would/could
be the owner of resources, it makes sense to inject them via the scopes as
well (since you know that whatever you injected this way is alive at that
point).

I think you would really like Rust. 

Java needs to stop trying to address every new paradigm that becomes hot. 

People wrote really great software in Java 1. This continual added complexity is only going to make it obsolete. 

If it doesn?t read like Java - it?s not Java - and it doesn?t belong. 

Create the fiefdoms elsewhere.

This sort of scoping isn't a new paradigm. It is equivalent to dynamic
scoping which was present in the original lisp introduced in 1960; it is
older than C.

Though, I think using scoping like this for resource management or
dependency injection is still rather new.

Yes. Use lisp if you want that. Java doesn?t need it. 

A great developer can write great code given tools they understand. If your hammer turns in a screwdriver that might be great for people needing a screwdriver. But they should have started with one. 

The complexity of a system cannot be judged by designer - it can only be judged by those that maintain it.

As I understand it, the demand for "life cycle scoping" is not
particularly met neither by the Java language nor by the Rust language.
I see nothing wrong with the need itself, nor see the Java language as an
impediment to meeting this need, but I do think there is a confusion about
what "scope" means in the name ScopedValue.
The need as expressed is about a kind of "scope" which is transversal to
lexical scopes and thread scopes.
But ScopedValue is expressly a restricted kind of thread local, which is
all about thead scopes.
Naturally, such a thing cannot express cross thread scoping requirements.
As Rosetta Roberts said, languages such as Lisp have special constructs to
express this kind of thing, but Lisp is way too different from Java and
Rust as I understand them.

What's horrible about it? You create a bunch of threads in a
StructuredTaskScope, and the threads handle tasks in that
context. Everything is nicely structured, so there's no need to
do anything underhand. Any time you need another worker thread
a StructuredTaskScope can fork one.

You're using scopes in exactly the way they are intended to be used.
No extra runtime checking is needed.

Thanks, that's clear enough.

OK, so it's possible for application code called from a framework to
override the caller's context, as long as that context was a parent
of the current context. That seems like a significant weakening of
the guarantees that scoped values provide.

I think what a previous poster referred to was that a forked task had no ability to retain a scoped variable (eg hold a reference in a static).

Although this has direct applicability in solving issues with a reusable buffer - it requires assistance from something like Rusts borrow checker so that a reference cannot be retained and only the contents copied - a signal to the developer that this is an expensive operation so do you really want to do this?

Although helpful it complicates things immensely and doesn?t feel like Java.

Indeed. In a previous version of scoped values we had something like

     ScopedValue.Snapshot aSnapshot = ScopedValue.snapshot();
     aSnapshot.run(aRunnable);

but this gives client code the opportunity to run in the context of an
old snapshot, which we do not want to be possible. Even if that old
context has not yet exited.

Which is why, I believe, it was discarded. I personally liked the snapshot
facility ? I invented it! ? but wiser heads prevailed.

First of all, I'm not sure why I can't type, but by "when down the line the
resource" I meant "channel down the resource" (not sure how this
monstrosity happened).

What I mean by "horrible", that such implementation is rather complicated
for what it wants to do, and is also very inefficient compared to what the
JDK could do.

Yes, and a few days ago I would have also said that it might weaken the
guarantees. However, you might have missed it in the infinite sea of
emails, but I have actually figured out a way how this can be implemented
[1]. The only problem is that the implementation is very inefficient
compared to the fact that it effectively just does what you wrote:
"override the caller's context, as long as that context was a parent of the
current context" (does it with an otherwise completely pointless
parallelization). See `CapturedScopes.withCurrentContext` (I called this
method `withCapturedContext` in a previous email, sorry for the
inconsistency).

That is, providing this feature in the JDK would not weaken any guarantees.

To be honest, I don't really understand what you mean. What I meant is
exactly what Andrew wrote: "override the caller's context, as long as that
context was a parent of the current context".

It is not like a borrow checker. The DI framework I used as an example is
just a way to show where such need would naturally arise. However, the
problem is more general. Consider that you are sharing a resource via SV
(please ignore the fact that I'm not hiding it behind an abstraction for
the sake of the example):

```
ScopedValue<MyResource> resourceRef = ScopedValue.newInstance();
void example() {
  try (var resource = new MyResource()) {
    ScopedValue.where(resourceRef, resource, () -> {
      foo();
    });
  }
}
```

There is nothing special here, `foo` might use the resource shared via an
SV. However, later I might realize that `foo` usually does not need the
resource, so it would be a waste to create it. So, I want to make the
creation of `MyResource` lazy. However, I have problem, because while I
could naively do something like this:

```
ScopedValue<MyLazyResource> resourceRef = ScopedValue.newInstance();
void example() {
  try (var resource = new MyLazyResource()) {
    ScopedValue.where(resourceRef, resource, () -> {
      foo();
    });
  }
}
```

where `MyLazyResource` will create the resource the first time it is
needed, and closes it if it was created. However, there is a problem with
the above code: The scope where `MyResource` is created changed. Even
worse: It is ill-defined now. And this problem would be solvable with my
requested method.

It's a very simple point.

If I allow an external framework to capture and re-use bindings later, then
that external framework *is* able to "re-bind context objects that I define
without going through APIs that I control."

It depends on what you mean by "re-bind context objects". I don't consider
running a task in a different context as rebinding. It is just that,
running a task in a different context, the API controls are not broken.

Also - as I have proven -  this is already possible with what we have in
Java 20, the only problem at this point is that currently it is inefficient
(and more error prone compared to if the JDK provided it). That is, you are
already allowing it, so the JDK is not protecting anything by not providing
this kind of SV capturing with an efficient method.

Refactor of the Java code with the introduction of MonitorSupport.
The aim is to capture the different implementation options as `policy` objects
so the code just delegates to the current policy. This also aims at clarifying
the initialization issues and enabling use of fast-lock synchronization earlier
in the VM initialization sequence.

But it doesn't do the same thing. It runs the code in another thread,
so per-thread guarantees are maintained. I'm fine with that. It's
always possible to hand a task from Thread A to Thread B, as long as
both threads co-operate.

We need the ability to revoke access.

Consider this scenario. You have a resource that is entirely
unsychronized, so must be accessed by only one thread at a time. A
thread-locked scoped value (called CAP) is used as a capability to
access the region. CAP is a handle which contains a reference to
the owning thread and a reference to the memory region.

Thread B needs access, so it requests CAP from the current owner,
Thread A. Thread A creates a new capability locked to Thread B, hands
it over, then continues executing, with its own CAP bound either
to null or to the new capability.

If some code now running in A had stashed a previous set of scoped
value bindings and could restore them, two threads A and B could now
appear to own the same memory region.

I see. Though in this scenario, I would consider that the code should have
not exposed the reference via the binding directly, but stored in a field,
and simply removed the field value.

Regardless, I accept this reasoning to be more careful due to the fact that
the thread might be used as an ID, and you might want to avoid some
reentrancy problems.

Anyway, knowing this, I will open a new thread soonish (sorry :)) with a
similar request which does not suffer from this potential issue (and tbh,
would be far more useful).

Thanks. From my side, I consider this request closed (maybe, some years
later, when we know more about how this is used, it can be reconsidered,
even if in a different manner).

Subject: Executor like scope
Message-ID: <CAKDaPBeGTHvv0LAihmM1Ad=fx-8JGrB_XbcyB=UoKW09FfHyVQ@mail.gmail.com>

Hi,

I would like to ask for a new type of scope in addition to
`StructuredTaskScope` which we already have.

For the general need, please consider the following scenario:

1. Let's assume there is a simple server which schedules a background job
for a specific HTTP request.

2. In such a server, we might assume that each HTTP request handler is
running in a particular scope.

Notice that, if we are scheduling a new job in the HTTP request, then we
can't do it in a scope, because the scheduled job has a longer lifetime
than the current scope, and even if we had an outer STS, we could not
directly call that, because STS does not allow a call from a child scope.
However, we might want to use the main application scope, which we can't,
if we just used a usual executor.

Still, I have created a POC [1] relying on STS that provides the equivalent
feature, I'm asking for. However, the problem with this is that it requires
a channel, which is needlessly inefficient. That is, an implementation of
this feature in the JDK could look very similar to STS, but would allow the
call from a child scope, and would return a `CompletableFuture` (or maybe
something similar) instead.

Hello Loom devs,

A long time ago on this mailing list, we read about Carrier classes, to implement stuff like message passing, Go channels, etc for the virtual threads of Loom.
Unless I am mistaken, I have read anything since 2020 about them [1] and [2].
How is this project going? Is it still a construct you are looking at, but are currently focusing on polishing Virtual Threads for their general availability?

Thanks for any comments on this,
Cheers

Olivier

One thing that is helpful to go with your question is to know if you've 
tried LinkedTransferQueue or any of the other blocking queues with 
virtual threads. Only asking because hearing feedback on using the 
existing APIs and hearing about any issues/limitations is always helpful.

Unfortunately no. I have been following that part from the distance. So far, I have use Loom on a prototype to replace a compute engine based on Counted Completer.

I was wondering about Carrier as I remember it to be a sort of channel and was fishing for updates out of curiosity, as I was reading again books about Erlang as well as playing with Clojure Async and its channels.

So, again, sorry for not being that helpful on the topic and thanks for any information

I guess one thing is that there isn't an easy way to mark a queue as
"closed" like golang channels. In Go an exception is thrown when we write a
value to a closed channel, and we can auto-stop iteration when the channel
is closed.

Telling the queue that the reader went away (maybe crashed) is still
awkward. It is less problematic with virtual threads, because you can
cheaply start a new virtual thread, and interrupt it more safely. However,
that is still not the best, because I want to be able to tell that I'm
ending the queue, not the thread (besides, I don't necessarily want to
start a new virtual thread, even if it is relatively cheap). Besides, the
distinction between closing the queue and doing some larger scope
cancellation (especially interrupting a thread) is still important, because
- sadly - quite often people swallow interrupted exceptions (sometimes even
respectable libraries). Also, while you might be closing the queue, you
might not want to interrupt code before and after queue processing. Though
it would lead deeper, using interrupt for cancellation is rather annoying
anyway (so much so, that I wrote a completely new executor framework mainly
because of that, and never looked back).

Subject: JEP 453, fixing a wildcard in the code
Message-ID: <986618831.74171603.1686123960076.JavaMail.zimbra@univ-eiffel.fr>

Hi all,
here is a minor fix to the code shown in JEP 453,
the type of "futures" uses a wildcard because the inference of scope::fork introduce it.

<T> List<Future<T>> executeAll(List<Callable<T>> tasks)
        throws InterruptedException {
    try (var scope = new StructuredTaskScope.ShutdownOnFailure()) {
    	  List<? extends Supplier<Future<T>>> futures = tasks.stream()
    	      .map(task -> asFuture(task))
     	      .map(scope::fork)
     	      .toList();
    	  scope.join();
    	  return futures.stream().map(Supplier::get).toList();
    }
}

I believe it's more readable to avoid inference and explicit set the type like this

      List<Supplier<Future<T>>> futures = tasks.stream()
          .map(task -> asFuture(task))
          .<Supplier<Future<T>>>map(scope::fork)
          .toList();
    
regards,
R?mi

Subject: Early access JDK 21 version

Hello -?
I have been playing around with Virtual Threads and Structured Concurrency. I love it.?
I was looking for the early access version for JDK 21 where the StructuredTaskScope and related classes are now moved into the java.util.concurrent package (from incubator).?
The Loom website sends me to an early access build site? which points to "Build 25 (2023/6/1)". But in this build the classes have not moved to java.util.concurrent package and Subtask is not defined.?
Which build for JDK 21 should I use to get latest changes to?StructuredTaskScope? apis? and where can I get it ??

The Project Loom EA page should list 3 JEPs that are integrated into JDK 
21. JEP 453 integrated into JDK 21 build 26 so any EA build from b26 on 
would be good to try.

Subject: Question about using virtual thread
Message-ID: <CABUmArTcxMw80QsSTuzmi1i9f=5UrSzzh2cuk6jm+tYg1vJ9ww@mail.gmail.com>

Hi I have several questions about using virtual threads in web application:

1. When using per-request-per-virtual-thread style programming model, a
general case would be to acquire a jdbc connection from some database
connection pool, launch a SQL request, and then release the connection. I
have some doubts that since database connections are usually a small
number(like at most 100 connections), most of the virtual threads are
waiting for them if requests come in quite fast. In this case, should I
limit the number of virtual threads to reduce unnecessary waiting?

2. Is it recommended to create like several thousands of virtual threads,
waiting to perform take() from a BlockingQueue infinitely? I noticed
pooling virtual threads is definitely not recommended, so I am a
little confused about this idea. which really sounds like pooling, but this
mechanism can control the virtual threads concurrency pretty easily.

3. Sometimes a request may needs to perform a SQL request, sometimes not. I
am wondering whether I should put the acquired database connection in a
ThreadLocal or a ScopedValue. In old times, ThreadLocal would be perfect
for this senario, however it seems that ScopedValue are preferred to be
used in virtual threads. I noticed that the object that ScopedValue holds
should remain unchanged during the method, but the unchanged object could
have changable fields. So if when I receive a Http request, I create a
object with a database connection field initialized as null, then when it
needs to perform a SQL request, acquire a database connection and then put
it into the ScopedValue's object, thus the later actions could all find it
and use it from the ScopedValue.
I don't know if it's recommended to use ScopedValue like this, which really
looks like ThreadLocal.

Please correct me if I am wrong, Thank you guys for your great work making
Java better !

With virtual threads, when a virtual thread block, another can run, so having a code that block is not an issue.

Pooling means re-using the same threads for different tasks, something you have to do with platform threads (OS threads) because starting a platform thread is slooooow. 
Starting a virtual threads is way faster, so pooling virtual threads is useless. 

Now with a virtual threads, the blocking cost is not a problem if there are other virtual threads that have some work to do. If all threads (virtual or not) are blocked but one, your code will scale poorly.

Please do not try to manage the SQL connections by hand. 
Use a DataSource object, it will do the SQL Connections pooling for you. 

The only thing you have to do to support virtual threads in your application is to update your JDBC driver to the most recent version because at least in the case of Postgres, previous versions of the driver were forcing each virtual thread to block the underlying platform thread.

Most usually DB pool implementations can be limited in which case they will
just wait until one gets put back to the pool. So, that would work with
virtual threads and would provide a natural connection limit. Another way
is simply to use a semaphore, which would limit the number of concurrent DB
usage. Say, you could create a method like this for a pool (and always use
it instead of getting a connection by other means):

```
void withConnection(Consumer<? super Connection> action) {
  semaphore.acquire();
  try (var connection = getConnection()) {
    action.accept(connection);
  } finally {
    semaphore.release();
  }
}

and then call it like this:

```
pool.withConnection(connection -> {
  // Do something with connection
});
```

The benefit of virtual threads is that it is fine to create a virtual
thread that will start by blocking on a queue indefinitely (unlike with
normal threads, where it would be a horrible waste of resources), and then
processes the element (you still have to care about the case, when nothing
gets added to the queue anymore of course).

Scoped values are still in preview, so you can't really use them in normal
production. But I think it would be better to use ScopedValue in the
future, because `StructuredTaskScope` automatically propagates them to
child threads (and I'm hoping we will get some other scope variants in the
future).

You shouldn't pool virtual threads at all if you don't do CPU heavy
processing, the most you do is limit the number of live virtual threads.

Pooling means you re-use the same instances, but when you use a virtual
thread you should forget about it after it is done, and create an entirely
different virtual thread for the next task. To limit the amount of virtual
threads you can use semaphores for this (still using a newThreadPerTask
-like executor).

You should create a single thread that infinitely run, receive an element
(from jbdc/queue/...) And fork a new task for this new element, see the
"fan-in" example in Structured Concurrency [1].

About the last point, I would recommend creating an object that handle the
connections and hides a ScopedValue.

Unrelatedly to the question itself, it is almost never a good practice to
have a non-private threadLocals/ScopedValues.

No, you should not. When a thread blocks waiting for something, behind the scenes you get the exact same queue you?d get if you tried to throttle manually, only easier to use. So just block and wait ? that?s what virtual threads do best. Of course, depending on what percentage of the threads actually need to access the database (as opposed to getting their data from a cache) the database may become your bottleneck.

It?s impossible to create more or less virtual threads than you need. Every concurrent task in your application is represented by a virtual thread. It?s not that pooling virtual threads is not recommended, it?s that it cannot possibly ever improve anything, and it could make things work. You never, ever, pool virtual threads. EVER.

Use whichever one you prefer. ScopedValues are not preferred for virtual threads; they?re preferred *always* in situations where their structured use fits their purpose. I wonder, though, why do you want to store the connection in the thread anyway. If you?re using a connection pool, you can just give it back and request again if you need to. If you do need to hold onto a connection for some reason, you probably need to close it or return it to the pool, so it sounds like somewhere in your thread you know when you?re done, which suggests that structured use would be possible, and if it?s possible ? it?s preferable.

*> why do you want to store the connection in the thread [local] anyway*

This is done today where we see methods annotated with `@Transactional.
That is, these methods initiate the beginning of the transaction acquiring
a connection [from a DataSource pool], the connection/transaction is put
into a ThreadLocal and is then accessible to code during the method
execution that needs/uses the transaction, and finally at the end of the
method scope the transaction is completed/ended including a call to the
underlying connection.commit() or connection.rollback() plus ensuring the
connection/transaction is removed from the ThreadLocal.

NB: I say the ThreadLocal has a connection/transaction because typically
it's not going to hold s java.sql.Connection directly per se but instead a
type that wraps a java.sql.Connection and deals with some details like
nested transactions (savepoints) etc.

If you see code today that has a method annotated with `@Transactional`,
then you are almost guaranteed that it will be using a ThreadLocal under
the hood to hold a "transaction" that in turn holds a  java.sql.Connection.

Cheers, Rob.

Subject: Question Regarding JEP 444: Virtual Threads and Use of ForkJoinPool
Message-ID: <CAMvTVw0irb8q+Opk47CbcMf5fz0Ji3KrsFfnNg9hqmVyoB_HYQ@mail.gmail.com>

Hello,

I was reading JEP 444, which discusses the implementation of Virtual
Threads. I've observed that the JDK's virtual thread scheduler employs a
work-stealing ForkJoinPool operating in FIFO mode, which is distinct from
the common pool operating in LIFO mode.

This has sparked my curiosity because ForkJoinPool, to my understanding,
has not traditionally been designed to handle I/O-bound tasks. However, the
design of virtual threads seems to be aimed precisely at addressing such
tasks.

Therefore, I'm curious as to why Java has opted to use the ForkJoinPool for
scheduling virtual threads. I would greatly appreciate it if you could shed
some light on what makes this design choice effective in managing I/O-bound
tasks, despite the ForkJoinPool's traditional usage patterns.

Thank you for your time and consideration. I look forward to your insights
on this subject.
* Thank you,*

Yes and it is the virtual threads mechanism that handles the I/O-bound 
tasks, not the underlying FJP. Where a regular thread in the FJP would 
block on an I/O operation and become unavailable for further use, it is 
the virtual thread that blocks, allowing the carrier thread in the FJP 
to continue executing other virtual threads.

David

It isn't the FJP that does that, it is the use of ForkJoinTasks and the 
associated APIs by the programmer that does that.

Refactor of the Java code with the introduction of MonitorSupport.
The aim is to capture the different implementation options as `policy` objects
so the code just delegates to the current policy. This also aims at clarifying
the initialization issues and enabling use of fast-lock synchronization earlier
in the VM initialization sequence.

Subject: Question Regarding JEP 444: Virtual Threads and Use of
 ForkJoinPool

And following on this question regarding FJP, is there any possible interaction between the virtual threads and any library externally using ForkJoinPools?

I am asking this question with this JUnit issue in mind https://github.com/junit-team/junit5/issues/3108
For example, if a test were to be executed by JUnit executor relying on the FJP, and if the test were using Virtual Threads, would we see interactions between those Virtual threads and JUnit executor, particularly through the test `thread instanceof ForkJoinWorkerThread`?

I am trying to build an example to see how the two will interact and see with my own eyes.

Thread.currentThread() will return the Thread object for the virtual 
thread, it won't return the underlying ForkJoinWorkerThread used as the 
carrier.

I'm not sure how to read the referenced issue. Does JUnit's parallel 
executor create its own ForkJoinPool to run tests or does it use the 
common pool? In any case, it will be a separate pool to that used for 
virtual threads.

To better understand the issue, I suggest reading the metaphor of this comment https://github.com/junit-team/junit5/issues/3108#issuecomment-1520174615
Yes, JUnit uses its own pool but there are unfortunate interactions across pools.
You mention that Thread.currentThread() returns a special object, so it should be ok to avoid this sort of issues.
I am still working on an example, to validate this.

Thanks for the answer

"special object" = the Thread object representing the current Thread.? 
If the test executor is looking at Thread.currentThread when I wouldn't 
expect any issues or interaction. However, if it's enumerating all 
platform threads, say with Thread.getAllStackTraces or 
ThreadMXBean.getAllThreadsIds, and assuming all ForkJoinWorkerThreads 
are controlled by the test executor, then it may get confused by other 
FJ worker threads.

It's possible this topic will come up many times. I wonder if anyone 
with experience in this area would have time to do an inventory of the 
JDBC drivers and the DB connection pools to see how they behave with 
virtual threads.? Oracle's JDBC driver, PostgreSQL JDBC driver, and a 
few others have JDBC drivers that work well with virtual threads but I 
have seen much on DB connection libraries. Do they provide API that wait 
for a connection to be available without pinning a virtual thread?

To be honest, I haven't actually tested with virtual threads, but dbcp2
relies on Apache Commons Pool2 which uses `GenericObjectPool` [1] for
pooling which uses `LinkedBlockingDeque` itself (no synchronized blocks or
native shenanigans), so I would expect it work well with Loom. Anyway, I
can write some tests on how well behaved these pools (with various
configurations) with Loom on the weekend.

Good day devs!
 I am considering the creation of a database server that is working on
thread-per-core architecture. So I have a question: do you have plans to
implement the possibility of using virtual threads executor on the base of
a passed executor?

P.S. I am aware of problems with synchronization inside JDK classes,
libraries, and pinned threads.

`ThreadPoolExecutor` already allows a custom `ThreadFactory` to which you
can pass `Executors.newVirtualThreadPerTaskExecutor()`. However, why would
you create a new server using loom on thread/core when you want to rely on
virtual threads? That just means that you are pooling virtual threads which
seems to be pointless (basically you are creating a queue in order to put
them in another). If you want to limit the number of concurrent access,
then you can do that with a semaphore.

Sorry, wrong copy paste, instead of
`Executors.newVirtualThreadPerTaskExecutor()` I meant
`Thread.ofVirtual().factory()` of course.

Hi Attila.
Cool! I want to implement an architecture that, for example, ScillaDB uses.
DB instances are sharded not by per server node but by CPU core node.
That allows us to avoid the usage of memory fences during the usage of
locks (additionally implemented, of course) and use a wider set of data
structures (because of the usage of cooperative concurrency).
There is a very cool presentation about such architecture in Hydar (if you
are curious to check it) - https://www.youtube.com/watch?v=JPTt1ny67x4

It doesn't seem to me that you want to pool virtual threads.

The thread-per-core architecture seems to benefit from using VM threads
directly, and wrapping it with a virtual thread will give you the cost of
the abstraction without the benefits.

If you want the benefits of the programming model of virtual threads (e.g.
not needing to use reactive-like programming) you need to guarantee that
your virtual threads run on a given pool of VM threads, something like e.g.

private static ThreadLocal<ThreadFactory> virtualFactory = new
ThreadLocal<>();

public static void fork(Runnable r) {
    // Run using virtualFactory.get()...
}

public static void main(string[] args) {
    for (/* core in cores */) {
      ThreadPerCoreExecuter(core, () -> {
         virtualFactory.set(Thread
               .ofVirtual()
               .factory(currentThread()));
          // The thread logic, while using `fork`
       });
    }
}

as far as I can remember, this is currently not possible

Yes, that is what I intended to say.

I'm not sure where you want to improve performance. Suppose we could create
multiple virtual thread groups (each with an arbitrary number of carrier
threads specified at group creation time). Assuming you have N cores, you
could create N such groups with a single carrier thread each (then you
somehow pin that carrier thread to a given core). Now you could execute
virtual threads on a given core, but then you seem to lose most of the
advantages, because virtual threads (even if they are running on the same
core) are concurrent, so you can't really avoid synchronization at this
point. Not to mention that you will get the overhead of virtual thread
scheduling. I think if you really want some very low level optimization,
then you probably have to use platform threads instead of virtual threads,
and then write your tightly optimized code there.

The ability to mound virtual threads on a specific thread pool(/executor)
is quite useful in general.

Practically all applications with UI will want a designated thread pool for
UI Vs the rest.

CPU heavy applications may want to use OS threads for most of the
application, but have 1/2 threads on the side to handle e.g. incoming
request, put them in a queue for the CPU heavy process, and wait for it to
finish before sending it onwards/returning a status.

In these cases the ability to use virtual threads on the part of the
application that it fits without interfering the other parts is currently
impossible.

As for the thread-per-core case, I don't see an immediate reason not to use
virtual threads over e.g. event loop, but I will admit that the low level
stuff is my weaker side

I agree that it would be useful for a couple of reasons. For example to
reduce the maximum latency. I just don't see the benefit for such a tight
low level optimization. As for UI: It wouldn't be useful I think, because
the UI frameworks are single threaded to avoid synchronization need, and
you can't really have that with virtual threads, because virtual thread
scheduling is not cooperative. For a UI framework (with `await` like
functionality of other languages) you need cooperation where you
effectively tell the framework that "while I'm waiting here, you can
process other things". That would - I believe - require the exposal of
continuation, or some specific support.

Attila,

While I understand and respect your opinion, I must disagree. Through
practical examples, it has become evident that thread-per-core architecture
and asynchronous IO are incredibly beneficial in database development.
These techniques are used in ScyllaDb and their SeaStart framework (written
in C) https://github.com/scylladb/seastar, and are demonstrated in a
project I took part in myself
https://www.datadoghq.com/blog/engineering/introducing-glommio/,
https://github.com/DataDog/glommio (written in Rust). The results have been
quite noticeable in practice.

Yes, we do have such plans, but I would strongly recommend against picking such designs before actually proving to yourself that they yield a significant benefit.

Thread-per-core is not generally faster than multi-core scheduling; in some particular situations it may be significantly faster, in other situations it may be significantly slower, while in some situations it can be pretty much the same. In particular, it works well when you have an efficient and well-balanced sharding scheme that ensures that the level of contention between two transactions is known in advance, and it is that knowledge that provides the most benefit. The primary optimisation is running transactions that are known to contend sequentially rather than in parallel; the lack of memory synchronisation operations is a secondary optimisation (because uncontended CASes are relatively cheap).

So I would suggest that you first focus on designing your database for a sharding scheme that fits thread-per-core well and on arranging your transactions accordingly, and only then reaching for lower-level optimisations. If you can?t get a significant benefit from the first part alone, you won?t get any from the second.

I do not doubt that. I just don't think that using virtual threads can
retain that advantage (though I always reserve the right to be wrong :)).
Because the greatest benefit is coming from not needing to use locks, in
which case you can just start N virtual threads, and be probably fine.

Regardless, I would love to see support for virtual thread groups with
distinct sets of carrier threads (or anything equivalent). I just don't
think that in your case that would bring a big advantage.

As for the usage of virtual threads in the UI event loop.
JetBrains utilizes virtual threads in the Compose Multiplatform UI
architecture's event loop. Kotlin coroutines accept the dispatcher (or
carrier thread/pool) and provide await functionality (as you mentioned
above).
But, correct me if I am wrong, channels can also achieve the same effect of
allowing other processes to be carried out while waiting.

Kotlin coroutines are cooperative, and they also allow you to use
continuation. Though I don't know their UI framework, in Kotlin's case it
is obviously possible.

I agree it can be beneficial, but you should beware of generalisations. Most of the work is not in the scheduling scheme but in designing the database and its user model in a particular way *so that* thread-per-core could then give an extra boost. Also, designs that work well in languages where heap allocations are generally expensive (C) don?t necessarily help to the same degree in languages where allocations are relatively cheap (Java).

A particular optimisation needs to fit your algorithm/data structure design as well as the language?s other constraints for it to be maximally effective.

Ron and team.
Thank you very much for your prompt responses and advices. I do value your
help.
We are evaluating the design now. I just wanted to be sure that in case we
will confirm the benefits of thread-per-core architecture we can rely on
virtual threads tooling.

Thread per core designs are almost exclusively beneficial for cpu bound loads. Unless your database is memory only it is difficult to understand how it will be beneficial. 

Additionally due to cache sharing I?d think you?d want to pool work loads by cpu not core to take advantage of the larger cache.

I wrote some tests for connection pools and JDBC drivers [1]. However,
currently I have added only a limited number of options (H2, Postgres with
loom-aware driver, Postgres with old driver) and DBCP2 for connection pool
with the addition of semaphore based "connection pool". Also, I haven't yet
run the tests for all combinations (since it takes a lot of time), but I
have at least verified that DBCP2 does improve with virtual threads
compared to if it completely pinned a thread.

The current setup is the following:

- Starts 2 * CPU times the following submit chains: "CPU action ->
Connection action -> CPU action -> Connection action". These 4 steps are
consecutive submits trying to deal with the unfairness of Loom.

- We have two ways to fork new tasks: One is to simply start a virtual
thread, the other tries to simulate carrier thread pinning by using an
executor: `Executors.newFixedThreadPool(CPU_COUNT)`

- Both for the "CPU action" and "Connection action" it is possible to sleep
instead, because a problem I run into is that it is sometimes hard to
detect the adverse effect of thread pinning, because if the DB is running
on the same machine as the test, then it won't matter much, since the DB
will make your CPU busy anyway.

While doing this I have noticed one thing however: H2 is very loom
unfriendly, because it is full of `synchronized`. The worst part is that at
some places they even documented that you can externally synchronize via a
synchronized block, meaning that if they are to fix everything, that will
be - in theory - a breaking change for H2. That said, I can't imagine
somebody using the same `PreparedStatement` and similar objects
concurrently. I'm in the process of trying to create a version of H2 from
which I remove all the synchronized blocks, but it takes quite a bit of
time.

Anyway, any tests, comments and improvements are welcome.

I don't know anything about DBCP2 but I'm curious to know if you really 
need to use a Semaphore with DataSource.getConnection. If it doing JDBC 
connection pooling then I would expect it would block, waiting for 
someone else to close a Connection and return it to the pool.

Thanks for the info on H2, will be interesting to see how your 
experiment goes.

You don't need it. For the semaphore case I'm not using a connection pool.
The reason I added it, because it is very simple, and I can reason about
its expected behaviour easier. Of course, in that case I'm not saving the
creation of a new connection, but I can still test thread pinning.

In that case, I can?t make any promises but custom schedulers are on our roadmap.

Both the JEP [1] and the original Loom proposal [2] state that running native code will pin the virtual thread to its carrier.

I am curious to learn more about the reasons and implementation challenges that cause this limitation. Does it have something to do with how the native code is managed by the JVM? Could you please point me in the right direction?

Virtual thread stacks move around in memory, as they?re stored in the Java heap. Frames of native code are hard to move around because they may contain pointers into the stack itself, which Java doesn?t know about. Because it isn?t much of a problem in practice ? ?upcalls" from native code to Java are rare in general, and blocking operations in upcalls are rarer still ? it isn?t a challenge worth solving at the moment.

Thanks Ron.

What about native code that doesn?t make an upcall but does a blocking operation directly (via OS syscalls or similar)? Are such cases also rare?

What would be the advice if someone is making blocking calls from their downcalls? It might not always be possible to rewrite it in Java.

If I am reading this correctly [1], it seems like the golang implementation is able to unmount goroutines.

Yes. But supporting those ? even if there was reason to ? would have been even harder, as Java has no control or knowledge over what native code does.

If those operations are both frequent and lengthy, they shouldn?t be done on virtual threads.

Go also locks the carrier thread in this arbitrary native case - and simply spawns a new one if needed.

Yes. But supporting those ? even if there was reason to ? would have been even harder, as Java has no control or knowledge over what native code does.

If those operations are both frequent and lengthy, they shouldn?t be done on virtual threads.

Do you have a source for this information? I would like to develop an understanding of the similarities/differences between the two implementations.

With virtual threads then this kind of thing would be possible if some 
of the interface to the scheduler were exposed. In particular the 
exploration into custom schedulers might have to expose some way to 
temporarily compensate for pinned threads. As Ron said, we haven't seen 
too many cases where there are upcalls from native code and where the 
Java code blocks. The other scenario of a downcall that blocks in a 
syscall is a lot more likely.

I would review the Go impl/docs I linked to. They did a lot of analysis - this is probably never worth it. If the bulk of the Java process is executing in C code you?re probably better off rewriting that in Java.

Right now, the only way to do this via JDWP is use the 
ObjectReference/InvokeMethod command (or JDI invokeMethod at the API 
level) to invoke HotSpotDiagnosticMXBean dumpThreads to generate a 
thread dump to a file. So not terrible when the debugger and target VM 
are on the same system or at least have access to the same file system. 
In the future, JDWP + JDI will require updates to define new 
commands/methods to find threads, the VirtualMachine/AllThreads command 
is not the right solution for virtual threads.

BTW: What does IDEA "Get Thread Dump" (camera icon) use?

Thanks Alan!

for now there's no special support for virtual threads in IDEA, that's 
why I'm asking :)

"Get Thread Dump" action gathers the information from the threads list 
provided by com.sun.jdi.VirtualMachine#allThreads.

Did a lot more testing, and here are my findings:

I have checked the following 4 DB pools: DBCP2, Hikari, C3P0 and VIBUR. All
of them seems to be virtual thread friendly, though it is very hard to
measure since even if they were not, they are just too fast. So, I mostly
base this on that I have inspected their source code, and they don't rely
on synchronized nor on native calls.

As for DB / JDBC drivers, it varies a lot more. For the testing setup, I
have started 4 times as many parallel actions as many carrier threads I
have, and wherever I write "sleep" I always mean a 60 ms sleep. So, when
running the jobs concurrently, then - without carrier thread pinning - the
benchmark should measure 60 ms (+overhead), while a complete pinning would
make it 240 ms (+overhead).

## H2 (com.h2database:h2:2.1.214)

It is not virtual thread friendly, since it is full of synchronized blocks.
To prove the problem empirically, I have created a variant of H2 with SLEEP
function, and indeed the benchmark measured 240+ ms. However, I have also
created a variant where I replaced every synchronized in H2 with Java 5
locks, and the measurement reported 60+ ms as expected.

I have reported this issue to the devs:
https://github.com/h2database/h2database/issues/3824


## HSQLDB (org.hsqldb:hsqldb:2.7.2)

The same as with H2, but I didn't repeat the experiment where I removed all
the synchronized.

It seems the development for the fix is already on its way:
https://sourceforge.net/p/hsqldb/discussion/73673/thread/e003a3a566/


## MariaDB JDBC driver (org.mariadb.jdbc:mariadb-java-client:3.1.4)

Seems virtual thread friendly.


## PostgreSQL JDBC driver (org.postgresql:postgresql:42.6.0)

The newest version (42.6.0) seems to be virtual thread friendly as
advertised. I have also checked the older version (42.4.3) before the fix,
and indeed, the older version completely pins the carrier thread.


## Derby (org.apache.derby:derby:10.16.1.1)

This is a bit weird, because for the explained setup, it completes the
benchmark in about 220 ms which is less than 240 ms, and I don't know what
to think about this, because if it pins the thread, then how could it
partially unpin during the sleep? If it doesn't, then 220 ms is awfully
slow, and with a normal query there is no such obscene overhead.

So, it doesn't seem to be virtual thread friendly, but I'm not sure.


## MsSQL JDBC driver (com.microsoft.sqlserver:mssql-jdbc:12.2.0.jre11)

Seems virtual thread friendly. Though there is noticeably more overhead
here than what the other drivers have, so maybe there is some small pinning
somewhere?


## Oracle

Haven't checked it, because it is rather inconvenient to install, but maybe
someone wants to? :) That said, I remember that many years back, I had to
step into the ojdbc jar checking a nasty bug in the driver I did quite a
bit of look around, and if memory serves me right, ojdbc is unsynchronized,
and uses only Java code, so it should be safe.


## Bonus: log4j / log4j2

I haven't measured this fully, but noticed that log4j2 is not virtual
thread friendly (holds an intrinsic lock while writing to a file), which is
rather awkward given how common logs are (and log4j2 is quite widely used).
I have checked logback as well, but that seems to be using Java 5 locks, so
luckily we can still rely on Ceki G?c? :)


If anyone wants to add some additional tests, then of course that is
welcome. The repository is at <https://github.com/kelemen/loom-db-test>,
and should build out-of-the-box (assuming you have JDK 20 installed in a
well known location). To reproduce the above, the most convenient way is to
run the following command:

`./jmh.sh
--testedDb="H2.SLEEP,H2.NOSYNC.SLEEP,HSQL.SLEEP,POSTGRES.SLEEP,POSTGRES.OLD.SLEEP,DERBY.SLEEP,MARIA.SLEEP,MSSQL.SLEEP"
--forkType="LIMITED_EXECUTOR,VIRTUAL_THREADS"`

Hi Attila,

For Oracle JDBC, I replaced almost all usages of ?synchronized? with a ReentrantLock. This change first appears in version 21.1. The driver is distributed on Maven Central:

<dependency>
    <groupId>com.oracle.database.jdbc</groupId>
    <artifactId>ojdbc11</artifactId>
    <version>21.9.0.0</version>
</dependency>

To detect thread pinning, you might try:
-Djdk.tracePinnedThreads=full

This system property is documented in JEP 444:
The system property jdk.tracePinnedThreads triggers a stack trace when a thread blocks while pinned. Running with -Djdk.tracePinnedThreads=full prints a complete stack trace when a thread blocks while pinned, highlighting native frames and frames holding monitors. Running with -Djdk.tracePinnedThreads=short limits the output to just the problematic frames.
https://openjdk.org/jeps/444#Executing-virtual-threads

Hope this helps.

Thanks,

Michael

The same as with H2, but I didn't repeat the experiment where I removed all the synchronized.

It seems the development for the fix is already on its way: https://sourceforge.net/p/hsqldb/discussion/73673/thread/e003a3a566/


## MariaDB JDBC driver (org.mariadb.jdbc:mariadb-java-client:3.1.4)

Seems virtual thread friendly.


## PostgreSQL JDBC driver (org.postgresql:postgresql:42.6.0)

The newest version (42.6.0) seems to be virtual thread friendly as advertised. I have also checked the older version (42.4.3) before the fix, and indeed, the older version completely pins the carrier thread.


## Derby (org.apache.derby:derby:10.16.1.1)

This is a bit weird, because for the explained setup, it completes the benchmark in about 220 ms which is less than 240 ms, and I don't know what to think about this, because if it pins the thread, then how could it partially unpin during the sleep? If it doesn't, then 220 ms is awfully slow, and with a normal query there is no such obscene overhead.

So, it doesn't seem to be virtual thread friendly, but I'm not sure.


## MsSQL JDBC driver (com.microsoft.sqlserver:mssql-jdbc:12.2.0.jre11)

Seems virtual thread friendly. Though there is noticeably more overhead here than what the other drivers have, so maybe there is some small pinning somewhere?


## Oracle

Haven't checked it, because it is rather inconvenient to install, but maybe someone wants to? :) That said, I remember that many years back, I had to step into the ojdbc jar checking a nasty bug in the driver I did quite a bit of look around, and if memory serves me right, ojdbc is unsynchronized, and uses only Java code, so it should be safe.


## Bonus: log4j / log4j2

I haven't measured this fully, but noticed that log4j2 is not virtual thread friendly (holds an intrinsic lock while writing to a file), which is rather awkward given how common logs are (and log4j2 is quite widely used). I have checked logback as well, but that seems to be using Java 5 locks, so luckily we can still rely on Ceki G?c? :)


If anyone wants to add some additional tests, then of course that is welcome. The repository is at <https://github.com/kelemen/loom-db-test>, and should build out-of-the-box (assuming you have JDK 20 installed in a well known location). To reproduce the above, the most convenient way is to run the following command:

`./jmh.sh --testedDb="H2.SLEEP,H2.NOSYNC.SLEEP,HSQL.SLEEP,POSTGRES.SLEEP,POSTGRES.OLD.SLEEP,DERBY.SLEEP,MARIA.SLEEP,MSSQL.SLEEP" --forkType="LIMITED_EXECUTOR,VIRTUAL_THREADS"`

Hi Attila,

For Oracle JDBC, I replaced almost all usages of ?synchronized? with a ReentrantLock. This change first appears in version 21.1. The driver is distributed on Maven Central:

<dependency>
    <groupId>com.oracle.database.jdbc</groupId>
    <artifactId>ojdbc11</artifactId>
    <version>21.9.0.0</version>
</dependency>

To detect thread pinning, you might try:
-Djdk.tracePinnedThreads=full

This system property is documented in JEP 444:
The system property jdk.tracePinnedThreads triggers a stack trace when a thread blocks while pinned. Running with -Djdk.tracePinnedThreads=full prints a complete stack trace when a thread blocks while pinned, highlighting native frames and frames holding monitors. Running with -Djdk.tracePinnedThreads=short limits the output to just the problematic frames.

Hope this helps.

Thanks,

Michael

Did a lot more testing, and here are my findings:

I have checked the following 4 DB pools: DBCP2, Hikari, C3P0 and VIBUR.

So, I mostly base this on that I have inspected their source code, and they don't rely on synchronized nor on native calls.

As for DB / JDBC drivers, it varies a lot more. For the testing setup, I have started 4 times as many parallel actions as many carrier threads I have, and wherever I write "sleep" I always mean a 60 ms sleep. So, when running the jobs concurrently, then - without carrier thread pinning - the benchmark should measure 60 ms (+overhead), while a complete pinning would make it 240 ms (+overhead).

It is not virtual thread friendly, since it is full of synchronized blocks. To prove the problem empirically, I have created a variant of H2 with SLEEP function, and indeed the benchmark measured 240+ ms.

Thanks, this system property eluded me for some reason. Anyway, I have
checked the DB pools by enabling it, and they - with the exception of DBCP2
- don't report any pinning. Even DBCP2 only uses `synchronized` when
returning the connection to the pool (seems trivially fixable in DBCP2).

I have tried to check the Derby anomaly with it, but still a bit puzzled,
because it indeed seems to pin the thread always on `executeStatement`.
There is some trickery there with potentially using the same lock for
multiple connections, but I don't see why that would happen. That said, I
didn't read its code that thoroughly.

Thank you for your report!

I have a question regarding H2. Not all pinning due to synchronized is harmful; in fact, most uses of synchronized are benign and need not (and perhaps should not) be replaced with ReentrantLock. It is when pinning is *both* frequent and long-running that it adversely affects virtual threads? scalability. Obviously, if you make the DB sleep inside a synchronized block that would qualify as a problem, but since H2 is an in-memory database, did you also detect a problem with H2 and more realistic uses?

To be honest, you are right, I'm a bit exaggerating the issue given how H2
is often used. Though it is possible to show the pinning issue (just easier
to make it obvious with a sleep). The simplest way to do it is to require
H2 to lock tables. For example, by running concurrent INSERTs, etc. on the
same table. In that case, H2 with all the synchronized will be magnitudes
slower (than my no synchronized modification). Also, there is a server mode
for H2 (not that I tested it, or ever heard anyone using it ...).

I would also argue that 99% (more?) of the common system calls used in an application are handled directly - that is they are turned into asynchronous calls by the JVM and the virtual thread properly moved off the carrier to allow another virtual thread to run.

Otherwise virtual threads would only affect cpu bound workloads - and then any context switching - user or OS is extremely expensive.

Virtual threads should only be used with workloads that do IO - if they don?t you should be using a thread pool for optimum performance.

I don't understand why this is even an issue. If the Java code calls
native code which blocks or calls back into Java code, then we'll need
a platform thread. We can't know what the native code does, and the
native code owns the platform thread for the duration. So that
platform thread has to exist, and we need one for each native blocking
call.

But the Java code required to do this is mot much more than:

     ExecutorService ex = Executors.newCachedThreadPool();

     public <T> T submit(Supplier<T> aSupplier)
             throws ExecutionException, InterruptedException {
         if (Thread.currentThread().isVirtual()) {
             return ex.submit(aSupplier::get).get();
         } else {
             return aSupplier.get();
         }
     }

I suppose we could provide a standard method which does this, but it's
not much of a big deal. But it probably makes more sense to leave this
to user code because then the user gets to decide policies for
timeouts, the size of the pool to use, etc.

I have installed Oracle the "normal" way, and spent like a day on
configuring it to my liking :)

Anyway, now with Oracle added, I think most relevant DBs are there.

Also, I have confirmed what you wrote by benchmarking
"com.oracle.database.jdbc:ojdbc8:19.19.0.0" against
"com.oracle.database.jdbc:ojdbc11:21.9.0.0", and as expected the new
version is considerably faster.

Subject: bug: breakpoints in in an anonymous class method executed on a
 virtual thread callstack are skipped
Message-ID: <CADS7o=4J2Obs80U31SeAYjzBBWuwFXDE++uiGnX2RnGpV95gEw@mail.gmail.com>

Investigating an issue in both IntelliJ and Eclipse debuggers led to this
bug: I can't break inside an anonymous class method of the form

```
new Object() {
  void test() {
    System.out.println("breakpoint here does not work");
  }
}.test();
```

due to a buggy interaction between JDWP and virtual threads. The console
statement in the example above does indeed print, i.e. it is executed.

What would the next steps be to help with investigating and resolving this
issue?

I really appreciate your effort on this project. It will be a great resource for Java programmers, regardless of which database they want to use.
Personally, I?m very happy to see the Oracle Database driver has held up to independent verification. We did a lot of testing on our end, but we don?t always think of everything.

Thank you!

? Michael

Hi Attila,

For Oracle JDBC, I replaced almost all usages of ?synchronized? with a ReentrantLock. This change first appears in version 21.1. The driver is distributed on Maven Central:

<dependency>
    <groupId>com.oracle.database.jdbc</groupId>
    <artifactId>ojdbc11</artifactId>
    <version>21.9.0.0</version>
</dependency>

To detect thread pinning, you might try:
-Djdk.tracePinnedThreads=full

This system property is documented in JEP 444:
The system property jdk.tracePinnedThreads triggers a stack trace when a thread blocks while pinned. Running with -Djdk.tracePinnedThreads=full prints a complete stack trace when a thread blocks while pinned, highlighting native frames and frames holding monitors. Running with -Djdk.tracePinnedThreads=short limits the output to just the problematic frames.

Hope this helps.

Thanks,

Michael

Writing a test case in jtreg would be very helpful. 
test/jdk/com/sun/jdi/BreakpointTest.java would be a good starting point 
for a new test. Note however this might be an IDE interaction issue, and 
you might not be successful in writing a jtreg test case the reproduces 
the problem. But that in itself would be useful to know.
