Subject: Scoped values polyfill
Message-ID: <CA+pw5EJq5AhW7V8VBCA77rigYJ76zO5zS7euRUTPAr9D447JRw@mail.gmail.com>

Hi,

I am feeling sad because from what I have gathered scoped values will be in
preview for next LTS.

I am looking to see if someone has a workaround that uses ThreadLocals in
such way that is compatible with scoped values. (I do not need for
structured concurrency, just a stack inside a single thread)

I would like to organize my code in such a way to use scoped values for
certain contextual information using a polyfill so when a LTS with scoped
values enabled (not preview) arrives I can just switch implementation.


Hope it makes sense what I am asking.

best regards,
Davor Hrg

The intrinsics for pin/unpin are new in JDK 24. Can you do a quick test 
with -XX:DisableIntrinsic=_Continuation_pin to see if it reproduces?

Sure, you just wrap ThreadLocal.set() and and ThreadLocal.remove() in a
try-finally. Or doe you need something more than that?

I iterated on this a bit more and think it might be RFR:
https://github.com/openjdk/jdk/pull/23142. I dug up an old bug number that
looked appropriate: https://bugs.openjdk.org/browse/JDK-8287788. Let me
know if you want to assign it elsewhere.

For others that might be interested,

I have received a suggestion that fits what I need.

------------------------------------------------------------------
I noticed your question on loom-dev, and because I am not registered, I
cannot answer there.

I know one API you can use for that: the opentelemetry context API:
https://javadoc.io/doc/io.opentelemetry/opentelemetry-context/latest/io/opentelemetry/context/Context.html
It's a very small standalone jar, and despite it's root to opentelemetry
(and despite what the javadoc says), it does not depend on the other
opentelemetry APIs, it is a clean isolated small reusable library.

You use it with try-with-resources and it stacks values one on top of the
other (even when reusing the same key).

There is an implementation difference with scoped values: when setting a
new value it keeps the old array of values intact (immutability) and then
does a copy-on-write of the whole array and inserts the new value. See
https://github.com/open-telemetry/opentelemetry-java/blob/main/context/src/main/java/io/opentelemetry/context/ArrayBasedContext.java
Instead, scoped values are chaining the values like a tree (immutable too)
which IMO is a better design when you can have millions of threads.

That said, since the opentelemetry context is extensible, you can emulate
the behavior of scoped values by implementing something else than
ArrayBasedContext if needed. Likewise, you can implement a different
storage than
https://github.com/open-telemetry/opentelemetry-java/blob/main/context/src/main/java/io/opentelemetry/context/ThreadLocalContextStorage.java
should
you need to.

Anyway, I think it does everything that you need. It would be very nice of
you if you could copy my answer to the mailing list to bring awareness to
others (I don't care if you cite me or not).

I hope this helps.

Cheers,
Jean-No?l

Subject: How is the preempt stub be like?
Message-ID: <13240393.O9o76ZdvQC@xtex1>

Hi!

I am working on porting JEP-491 to LoongArch (it is not in the upstream 
OpenJDK, also I am not employed to do that, just an amateur).
I am trying to understand the code in [1].

When a monitorenter is called, StubAssembler::epilogue will be asked not to 
restore the stack pointer from frame pointer register.
The comment says "fp restored from the stub would be invalid" when the current 
frame is frozen. I wonder if there are any documentation about how does the 
freezing process happen and why FP is invalid but FP and return address (RA) 
loaded from the address pointed by SP is still valid?

Thanks!

The FP value that was restored from the stub is invalid because it 
contains a pointer to the stack that was created in the prologue before 
freezing. But when we thaw the frame, it will most likely be copied at a 
different memory address. The FP loaded from SP in the epilogue is the 
original value from the compiled caller, and it never holds a pointer to 
the stack unless PreserveFramePointer is used. In that latter case the 
value would be fixed during the thaw operation (check use of 
PreserveFramePointer).

Subject: ScopedValue API
In-Reply-To: <CABDM8gA+FsNyYcHRO2MZYCSbRC0d6JkPtsdf-XnPU6OVHyHn_g@mail.gmail.com>
References: <7faa6070-9e2f-4497-880a-d7c57ccb8d6a@zeus.net.au>
 <CABDM8gA+FsNyYcHRO2MZYCSbRC0d6JkPtsdf-XnPU6OVHyHn_g@mail.gmail.com>
Message-ID: <0f79042f-f5da-490a-8d40-b4e56d47345d@zeus.net.au>

Having had the opportunity to use ScopedValue to replace ThreadLocal, it 
was suggested I might provide some feedback here.

Background: I'm maintaining an OpenJDK fork that retains SM, I merge 
weekly from upstream, this isn't for untrusted code, it's just ensuring 
permissions are only granted to authenticated users using trusted code 
(checked using a SHA256 message digest, or CodeSigner).? I have good 
fortune; I'm not constrained by strict backward compatibility, nor am I 
attempting to create a Sandbox (Graal would be a better place to 
quarantine untrusted code). Permission is no longer Serializable, 
allowing obsolete serial form to be dropped and fields made final.

AccessControlContext is immutable now too, this was necessary, as I'm 
replacing AccessController functionality using ScopedValue to decorate 
doPrivileged calls, with AccessControlContext and the caller Class, and 
StackWalker is used to determine the stack context.

AccessController is initialized very early during the vm initialization 
phase, so initially it just runs privileged calls and returns privileged 
context, until init phase 3 is reached. ScopedValue, Stackwalker and 
other classes depend on by them are initialized prior to init phase 3 
from a static method in threads.cpp.

The second use of ScopedValue is to prevent StackOverflowError occuring 
in a SecurityManager implementation, called CombinerSecurityManager, so 
called because it uses a DomainCombiner to execute permission checks on 
all ProtectionDomain's in a stack concurrently, but more importantly it 
contains a non-blocking timed and weakly reference cache, that uses Doug 
Lee's ConcurrentSkipListSet to cache the results of permission checks 
for AccessControlContext, in a ConcurrentMap. In a system running many 
tasks with the same context, this makes a big performance improvement, 
by avoiding repeat permission checks. ? Previously StackOverflowError 
was prevented using a ThreadLocal variable, with a counter that was 
incremented each time recursion occurs, in try - finally blocks, to 
ensure that it was decremented each time any recursion completed, once 
the counter reached a limit, an exception was thrown.?? However 
ScopedValue is a much better fit since it uses recursion, it doesn't 
require any try - finally blocks.

CombinerSecurityManager is also using virtual threads to perform 
permission checks on each ProtectionDomain, to avoid blocking on 
platform threads when SocketPermission, FilePermission, are inevitably 
checked.?? There are also a non-caching Policy provider and policy 
parser implementations, that parse and stores policy grants in an 
immutable form following safe publication, it uses thread isolation to 
prevent contention on PermissionCollection instances.? There is a policy 
writing tool, that generates polp policy files.

ProtectionDomain now implements equals and hashcode methods, the 
hashcode is final and calculated during construction.? The reason for 
this is many ProtectionDomain instances are created for a Subject's 
Principal[]'s and caching their result improves performance.? Similarly 
AccessControlContext also now has a final hashcode calculated during 
construction.

I've also added support for privileged context to virtual threads, to 
allow virtual threads to be used with privileges, just like platform 
threads.

There are two test failures which occur due to the new AccessController 
functionality, with both platform threads and virtual threads.

I looked into the values of the Thread's inherited and Snapshot's 
Carrier, neither contain the ScopedValue used by AccessController.?? It 
may have something to do with earlier class initialization, I'm still 
trying to determine the cause.

#23142 has been merged, thanks a lot for the engaging low-latency reviews!

One thing I found interesting here: the only really satisfying approaches
use JDK-private apis (Carrier-TL, pinning). These apis are not available to
application code that will face the same issues when making foreign
calls. Maybe this points out a gap in the public apis --- I'm still curious
about possible designs here that extend carrier- local critical sections
(aka pinning) just enough around a native call, maybe as an MH combinator.

What an app has going for it, though: this matters in really tight loops,
and app code has much better context knowledge to provision reusable buffer
space outside the loop (even in a ScopedValue), at which point the cost of
provisioning that space will matter much less.

Hi Matthias, (cc'ing Per)
I believe we have some ideas on how to generalize the approach you used 
for speeding up the Linker, and we will follow up with more details on 
this soon.

Cheers
Maurizio

Subject: Another virtual threads migration story: ReentrantReadWriteLock
Message-ID: <CANGKH61D2WVDQBJkU-cj1m9CWDPavMm178PRVveMj09m3fU-Jw@mail.gmail.com>

Hi folks,

As you may remember from a few months ago, we converted our LDAP Directory
server/proxy[1] over to using virtual threads. It's been going pretty well
and we're lucky enough to be able to leverage JDK21 as we have full control
over most (not all) of the code-base, which puts us in the enviable
position where we can convert code to avoid thread pinning issues. That
being said, we regularly test using the latest JDK24 EA builds as well.

We recently hit what I feel is quite a major limitation in
ReentrantReadWriteLock, which was somewhat hidden before in the old world
of large-but-not-super-large platform thread pools:

    Error: Maximum lock count exceeded at
ReentrantReadWriteLock.java:535,494 AbstractQueuedSynchronizer.java:1078
ReentrantReadWriteLock.java:738 ...

I'm sure that we're not alone in making extensive use of RW locks for
synchronizing configuration changes to runtime components: the write lock
ensures that regular processing is paused while the configuration change is
applied. The component in this case could be something that talks to a
remote microservice over HTTP, a logging backend, etc. In this case, there
is no configuration change - just a few 100s millisecond latency in the
remote service for some reason (e.g. GC pause?), which has caused many
virtual threads to get blocked inside the component while holding the read
lock. The RW lock then fails with the above error once there are 64K
concurrent threads holding the read lock.

Given that scaling IO to millions of concurrent IO bound tasks was one of
the key motivations for vthreads, it seems a bit surprising to me that a
basic concurrency building block of many applications is constrained to 64K
concurrent accesses. Are you aware of this limitation and its implications?
A workaround now is to go hunting for RW locks in our application and using
alternative approaches OR, where the lock is in a third party library (e.g.
logging / telemetry), wrapping the library calls in a Semaphore limited to
<64K permits. It seems a bit unsatisfactory to me. What do you think? Are
there plans to implement a RW lock based on AbstractQueuedLongSynchronizer?

Kind regards,
Matt

Nice catch! I am not sure you are going to get a resolution on this other than using your own implementation. 

The AbstractQueuedSynchronizer needs to be changed to use a long to hold the state - which will break subclasses - so it probably won?t happen.

But tbh, blocking that many threads seems doesn?t seem efficient or performant. It is isn?t cheap. I would think that a copy on write for the configuration change would be a better solution.

That's my fear Robert. I'm raising awareness so at least it can be
mentioned in the openjdk virtual threads migration guide if they feel it is
of sufficient importance.

Just to be clear, the threads are not blocked on the write lock here. They
have all successfully acquired the read lock.

But I agree, copy on write is an alternative approach when available,
otherwise it's semaphores all the way down...

Given that, it still seems the writer (configuration changer I assume) is going to be potentially stalled a long time.

In my experience, copy on write is ideal for configuration change management - it doesn?t work for things like db transactions - but I am not sure you would ever have millions of connections to a db - more like a request queue would be used by the clients, so it wouldn?t be an issue.

Interestingly, Go doesn?t even have a reentrant lock in their stdlib.

Once the write lock has been requested, no new read locks will be issued 
(since Java 6, in Java 5 there was an issue with starvation), so it 
could take a bit of time, depending on how long each of the operations 
is, but eventually it should do the write.

I'd investigate using StampedLock with tryOptimisticRead() and then 
writeLock(). The idioms are a bit more complicated, but this will 
hopefully work.

          * Lock state is logically divided into two unsigned shorts:
          * The lower one representing the exclusive (writer) lock hold count,
          * and the upper the shared (reader) hold count.

I have no love at all for arbitrary limits, and this certainly sounds like
one. And you may be right that these days it's something that might happen
in real-world deployments.

Here's a suggestion: it shouldn't be madly difficult to rewrite the code so
that instead of an int split into two unsigned shorts, it uses a long split
into two unsigned ints. Why not give that a try, and see what happens?
Building OpenJDK on most platforms is fairly straightforward these days.

Once you have some information about how well it works in practice, it may
be appropriate to talk to Doug Lea, the author, about removing the limitation.

I'm not sure this is a true statement. The synchronizer base class
(`ReentrantReadWriteLock.Sync`) which is being used appears to be
package-private; it should be possible to change it to extend
`java.util.concurrent.locks.AbstractQueuedLongSynchronizer` instead of AQS,
and use a larger (perhaps up to 31 bit) counter without impacting anything
that I can easily find. I don't see any place where extending these
counters would necessarily impact subclasses.

Look at the getState() method which is on the AbstractQueuedSycnhronizer class - that is part of the public API. AbstractQueuedSynchronizer is public and designed to be subclassed.

To clarify - the ReentrantLock uses a Sync that extends AbstractQueuedSynchronizer, and uses the ?state? - which is an int - within that.

The JDK authors could rewrite the ReentrantReadWriteLock and create a Sync that does not extend AbstractQueuedSynchronizer - basically fork that into one that uses a long for the state.

The component in this case could be something that talks to a remote microservice over HTTP, a logging backend, etc. In this case, there is no configuration change - just a few 100s millisecond latency in the remote service for some reason (e.g. GC pause?), which has caused many virtual threads to get blocked inside the component while holding the read lock. The RW lock then fails with the above error once there are 64K concurrent threads holding the read lock.

Are you aware of this limitation and its implications? A workaround now is to go hunting for RW locks in our application and using alternative approaches OR, where the lock is in a third party library (e.g. logging / telemetry), wrapping the library calls in a Semaphore limited to <64K permits. It seems a bit unsatisfactory to me. What do you think? Are there plans to implement a RW lock based on AbstractQueuedLongSynchronizer?

More of a practical limit than an "arbitrary" one.  Noone was going to 
hit 64K contending platform threads. And requiring general 64-bit atomic 
operations back when 32-bit was still very much mainstream, would not 
have produced an efficient implementation.

Simply rebasing to extend AbstractLongQueuedSynchronizer instead of AQS, 
as others have suggested, may "just work".

Though I meant to add that I think you will run into other scalability 
issues once you are dealing with such large numbers of threads.

Thanks for all the responses.

I'll respond to a couple of common themes in the responses:

* there is *no* contention on this lock. All threads have successfully
acquired the read lock. There are no writers and very unlikely to ever be
any writers in a production system
* RW locks are more defensive programming to ensure the application remains
functional in a non-production environment (dev/staging) when configuration
changes are made at run time. Use of RW locks for this purpose is a simple
design pattern, which is easy to understand and implement by any developer
* when runtime configuration changes can occur in production, I agree
alternative synchronization techniques should be used, which have been
proposed in this thread. Example use-cases include TLS key rotation,
service discovery events adjusting load-balancer config, etc
* this finding implies that RW locks cannot be used for simple
zero-contention defensive use-cases described above, at the moment anyway.
Conversely, I do expect virtual threads to be used in numbers greater than
64K, or I've been mis-sold :-)
* final point: sometimes it's not so easy to change the synchronization
implementation, such as when it is buried inside a third-party library.

I think I'll take the safest approach for now, bearing in mind the last
point above, which is to throttle the total number of concurrent requests
to 64K, which "ought to be enough for anybody" :-)

Thanks,
Matt

There was some brief discussion about this in the past, but I think 
mostly in the context of Phaser rather than RRWL. The "configuration 
change" usage where a huge number of concurrent threads hold the read 
lock to exclude a rare config change is a good motivation to look at 
this. I've created JDK-8349031 [1] to track it.

I agree. My use of "arbitrary" was perhaps careless, but the limit appears
arbitrary today.

Indeed.

That was that was my point, really: experimentation is needed.

I had assumed for an embarrassing amount of time that ScopedValue would not allow null. So much so that I could not understand why its API looked like Optional.

Given that ScopedValue goals are to make things easier it seems that not allowing null might be helpful.

Thoughts?

(Alan had mentioned on reddit that this topic was OK and I assume I'm posting in the right place. If not advance apologies.)

Hi Adam!
One of the "classic" examples for ScopedValues is communicating the
Principal associated with a session in some framework.
Should we require that frameworks must, for anonymous sessions, set the
Principal to some NoPrincipal object instead of null?

Following on from my suggestion to consider using StampedLock instead of 
ReentrantReadWriteLock - a word of warning that we cannot use it as a 
drop-in replacement with new StampedLock().asReadWriteLock(), because it 
does not have writer starvation protection. RRWL does. In your example, 
with millions of readers and one occasionally writer, the write lock 
might never become available. Here is a small example:

import java.util.*;
import java.util.concurrent.*;
import java.util.concurrent.locks.*;

// Based on email discussion in loom-dev on 2025-01-29 entitled:
// Another virtual threads migration story: ReentrantReadWriteLock
public class StampedLockRWLockStarvation {
 ??? public static void main(String... args) throws InterruptedException {
 ??????? var rwlocks = List.of(new ReentrantReadWriteLock(),
 ??????????????? new StampedLock().asReadWriteLock());

 ??????? for (ReadWriteLock rwlock : rwlocks) {
 ??????????? if (checkForWriterStarvation(rwlock) > 1_000_000_000) {
 ??????????????? throw new AssertionError("Writer starvation occurred!!!");
 ??????????? } else {
 ??????????????? System.out.println("No writer starvation");
 ??????????? }
 ??????? }
 ??? }

 ??? private static long checkForWriterStarvation(ReadWriteLock rwlock) 
throws InterruptedException {
 ??????? System.out.println("Checking " + rwlock.getClass());
 ??????? try (var mainPool = Executors.newVirtualThreadPerTaskExecutor()) {
 ??????????? mainPool.submit(() -> {
 ??????????????? System.out.println("Going to start readers ...");
 ??????????????? try (var pool = 
Executors.newVirtualThreadPerTaskExecutor()) {
 ??????????????????? for (int i = 0; i < 10; i++) {
 ??????????????????????? int readerNumber = i;
 ??????????????????????? pool.submit(() -> {
 ??????????????????????????? rwlock.readLock().lock();
 ??????????????????????????? try {
 ??????????????????????????????? System.out.println("Reader " + 
readerNumber + " is reading ...");
 ??????????????????????????????? Thread.sleep(1000);
 ??????????????????????????? } catch (InterruptedException e) {
 ??????????????????????????????? throw new 
CancellationException("interrupted");
 ??????????????????????????? } finally {
 ??????????????????????????????? rwlock.readLock().unlock();
 ??????????????????????????? }
 ??????????????????????????? System.out.println("Reader " + readerNumber 
+ " is done");
 ??????????????????????? });
 ??????????????????????? try {
 ??????????????????????????? Thread.sleep(500);
 ??????????????????????? } catch (InterruptedException e) {
 ??????????????????????????? throw new RuntimeException(e);
 ??????????????????????? }
 ??????????????????? }
 ??????????????? }
 ??????????? });
 ??????????? Thread.sleep(1800);
 ??????????? System.out.println("Going to try to write now ...");
 ??????????? long timeToAcquireWriteLock = System.nanoTime();
 ??????????? rwlock.writeLock().lock();
 ??????????? try {
 ??????????????? timeToAcquireWriteLock = System.nanoTime() - 
timeToAcquireWriteLock;
 ??????????????? System.out.printf("time to acquire write lock = %dms%n",
 ??????????????????????? (timeToAcquireWriteLock / 1_000_000));
 ??????????????? System.out.println("Writer is writing ...");
 ??????????????? Thread.sleep(1000);
 ??????????? } catch (InterruptedException e) {
 ??????????????? throw new CancellationException("interrupted");
 ??????????? } finally {
 ??????????????? rwlock.writeLock().unlock();
 ??????????? }
 ??????????? System.out.println("Writer is done");
 ??????????? return timeToAcquireWriteLock;
 ??????? }
 ??? }
}

With ReentrantReadWriteLock, once we ask for the write lock, no more 
read locks are issued until that has been serviced.

Using the correct idioms for StampedLock with tryOptimisticRead() should 
avoid this starvation, but we do have to be careful that we might be 
reading in-progress writes.

StampedLock would not have a practical limit on number of concurrent 
reads AFAIK.

Subject: Should ScopedValue even allow null?

I assume if one did not have a  null sentinel available they could use `Optional<Principal>` ? 

This would be the case of something can be bound but missing correct? Using `Optional` for many might even be more desirable for some that prefer that over dealing with `null` or sentinel. 

Part of what makes me concerned with ScopedValue taking `null` is the confusion with existing methods named `ScopedValue.orElse` (I promise I won't go into poly null): 

See even if you give `orElse` a nonnull as its second parameter you could still get a `null` in the case that null is bound! 

I think that is confusing for folks that have used orElse on `Optional` where if the input is null it will never be null.

Thanks for the helpful example demonstrating the fairness differences
between the two types of lock.
