Subject: New candidate JEP: 491: Synchronize Virtual Threads without Pinning
Message-ID: <20241002130433.7264977CE2F@eggemoggin.niobe.net>

https://openjdk.org/jeps/491

  Summary: Improve the scalability of Java code that uses synchronized
  methods and statements by arranging for virtual threads that block in
  such constructs to release their underlying platform threads for use
  by other virtual threads.  This will eliminate nearly all cases of
  virtual threads being pinnedjep444-pinning to platform threads, which
  severely restricts the number of virtual threads available to handle an
  application's workload.

After quite a bit of experimentation, I can at least say that last level
cache aware task placement on 4th Generation EPYC (Genoa) is a real boon. I
generalised my original approach, because it doesn't involve customizing
the nodes-per-socket setting (which we can't do on AWS anyway, NPS = 1),
introduce the risks/complexity of processor isolation and per-thread
affinity, or make the scheduler's life too difficult:

https://github.com/DanielThomas/virtual-threads-cluster-aware/blob/main/src/main/java/com/netflix/sandbox/ClusteredExecutors.java

With virtual-to-virtual-thread submissions and particularly structured
concurrency providing a heuristic for locality, I'm convinced there's a
significant opportunity here. I've still got some more real world
experiments to run, but will get a TechBlog post up when I have something
to share.

Thanks for the update, it's nice to get periodic "status reports" on 
experiments in this area.

One issue that I assume will be problematic without API support is when 
a virtual thread T unparks another virtual thread. The execute method 
will be called in the context of currentThread=T, not T's carrier. Until 
recently it was called in the context of T's carrier (for reasons that 
are too complicated to get into here) which has a bunch of implications 
that have now been smoothed out. For your experiments I suspect this 
means it will fallback to round robin or choose a random pool. It's a 
topic that needs a more thought as some custom schedulers will need the 
carrier's identity or maintain a mapping of virtual thread to "place", 
"place" in this case is the cluster.

I?d wondered about the external submit changes; I?ll take your word for it
:)

Does seem that if you do expose an API, you?d want to differentiate things
such as unpark/yield from other submissions.

I guess there?s also pathological cases where a VT is primarily driving
creation of virtual threads in an application. I?ve tried a few heuristics
for deciding when to externally submit instead of locally submitting to a
FJP, and I found it difficult to avoid prematurely and ineffectively moving
work; but I am working with purposefully contrived benchmarks right now,
rather than something that looks like a real application.

Subject: Can StructuredTaskScope be generalized?
Message-ID: <A871D470-BBAA-4256-A13A-E91FE667C321@oracle.com>

Hi,

StructuredTaskScope looks nice but in its current form it might be better named StructuredThreadScope, as the implementation is a class that?s tied to threads by its constructor. There are other situations where it's useful to group concurrent tasks, even without threads getting involved:

- Processes
- Raw continuations/fibers if they are ever added
- Work done on remote systems via RPCs

For example, an SSH library might want to let you invoke multiple processes on a remote system and join on them completing.

It might be worth generalizing the API a bit by making StructuredTaskScope an interface and introducing StructuredThreadScope as a class that implements it using threads. StructuredTaskScope would gain another type variable defining what gets submitted:

/**
 * @param R the result type of tasks executed in the task scope.
 * @param T the type of the tasks themselves.
 */
interface StructuredTaskScope<R, T> {
    <U extends R> StructuredTaskScope.Subtask<U> fork(T task);
}

? and then the thread based instantiation would take callables as normal.

class StructuredThreadScope<R> implements StructuredTaskScope<R, Callable<? extends R>> {
    public StructuredThreadScope(ThreadFactory factory) { ? }
}

Then if someone wanted to implement the same interface on top of some other concurrent system that can?t accept arbitrary lambdas, they could.

This is a minor piece of feedback because the interface is quite simple and other concurrent systems can just duplicate it under a different name, but it?d be nice if that wasn?t necessary.

thanks,
-mike

In-Reply-To: <A871D470-BBAA-4256-A13A-E91FE667C321@oracle.com>
References: <A871D470-BBAA-4256-A13A-E91FE667C321@oracle.com>

A StructuredTaskScope is a local control mechanism meant to be created, destroyed, and typically accessed only from within a single method. For that reason, abstracting it further would yield little benefit.

Indeed, for this reason, STS is presented as being merely the first instance of a structured concurrency construct in the JDK, and others may be added. It is perfectly okay, and even expected, for method foo to use STS for structured concurrency and for method bar to use another, just as foo may use a while loop and bar a for loop, or for foo to use `if` and for bar to use `switch`. This is by design, since we feel that structured concurrency is not yet fully understood.

Furthermore, STS has some semantic features ? its interaction with ScopedValues and with the observability of thread trees (represented by the internal ThreadFlock class, which may be exposed directly in the future to be used by other thread-based structured concurrency constructs) ? that cannot be naturally offered by non-thread-based structured concurrency.

So while it?s possible that in the future we may add some super-interface that STS implements, my question to you is this: even supposing there is some higher meaningful abstraction to be extracted here (and there probably is), what is the actual use of representing it with a Java interface given that an STS instance should never be shared among methods by storing them in a field or, indeed, should rarely even be passed from one method to another? In other words, supposing structured concurrency constructs for processes were added to the JDK in the future, what practical benefit is there to having them share a common Java interface with STS?

One such benefit I could see is sharing the documentation, and with it the understanding of how all implementations of such an interface should behave. But I think we don?t have sufficient understanding of what?s really required of ?structured concurrency? to make a commitment to an actual Java interface just yet. Without better understanding, we may end up with a whole hierarchy of interaces ? one requiring only nested lifetimes, another additionally requiring the propagation of errors and cancellation, yet another additionally inheriting ScopedValues etc. ? that aren?t practically useful.

Virtual threads unparking other virtual threads will be common, anything 
CSP like, or using locks that are contended, means the custom 
scheduler's execute method will be called in the context of a virtual 
thread that is unparking another virtual thread.

Very application dependent as to whether you'll see virtual threads 
starting other virtual threads. A web server where the listener is a 
platform thread may start a virtual thread for each connection, not too 
interesting. However, anything using structured concurrency where there 
the tree goes beyond a single level will lead to virtual threads forking 
new virtual threads.

I don't think we are close to exposing any API at this point. There is 
list of possible things that could be interesting but it's a big step to 
commit to an interface.

That?s fair enough, but I think there?s still value in a quick rename now, as ?thread? is more precise and frees up the word ?task? for a later abstraction (if any).

For the rationale, it could have future benefits like:

- The usual you identify such as sharing of docs, rapid communication of semantic promises.

- Tooling integrations, like IDE inspections that detect if you forget to call join or debuggers that can visualize task scopes.

- Maybe in future some dedicated language syntax appears, or does in other JVM languages.

I don?t know, it just seems more general to leave open the door to a future abstraction with the most obvious name. Otherwise there?ll be the question of how to generalize the name StructuredTaskScope when that name seems already fully general.

It is perfectly okay, and even expected, for method foo to use STS for structured concurrency and for method bar to use another, just as foo may use a while loop and bar a for loop, or for foo to use `if` and for bar to use `switch`. This is by design, since we feel that structured concurrency is not yet fully understood.

In other words, supposing structured concurrency constructs for processes were added to the JDK in the future, what practical benefit is there to having them share a common Java interface with STS?

But I think we don?t have sufficient understanding of what?s really required of ?structured concurrency? to make a commitment to an actual Java interface just yet. Without better understanding, we may end up with a whole hierarchy of interaces ? one requiring only nested lifetimes, another additionally requiring the propagation of errors and cancellation, yet another additionally inheriting ScopedValues etc. ? that aren?t practically useful.

StructuredTaskScope [1] is all about tasks splitting into concurrent 
subtasks. Yes, there is a new thread started to execute each subtask but 
the user facing API doesn't deal in Thread objects. We are always on the 
look out for a better name but I don't think renaming this to include 
"Thread" in the name would work.

The interface in your first mail looks more like an Executor in that it 
forks something. Maybe there is useful abstraction hiding but STS is not 
something that you pass around, meaning you aren't going to invoke a 
method in a faraway library with your STS as a parameter.

 C2_MacroAssembler::fast_lock
Message-ID: <W0ji-X_7uuqV0RmRFaYyGkGouuuZJ6IcOclh14oucBk=.84a1d184-50ad-4be1-b3e2-11b1961120da@github.com>

This is a small improvement for `C2_MacroAssembler::fast_lock`. Currently, we reuse `disp_hdr` (alias of `tmp1Reg`) to hold the loaded current thread id, which means we need to reload markWord from object into displaced_header into `disp_hdr` for later use in recursive lock case. This change simply reserves one extra temp register 'tmp4reg' in order to hold the loaded current thread id like friend `C2_MacroAssembler::fast_lock_lightweight`, which would help avoid such a reloading of markWord. This also fixes one code comment of `C2_MacroAssembler::fast_lock_lightweight`.

Testing performed on linux-riscv64:
- [x] make test TEST="hotspot_loom jdk_loom" (release build)
- [x] make test TEST="hotspot_loom jdk_loom" TEST_VM_OPTS="-XX:+VerifyStack -XX:+VerifyContinuations" (fastdebug build)

Things that felt strange or annoying:

  *   When subclassing StructuredTaskScope I always have to @Override `join` and `joinUntil` to return my subclass type to provide a fluent api.
  *   When subclassing StructuredTaskScope @Override `handleComplete` I find myself wanting to write a switch expression on Subtask#state(), but if I do, I always need to have a case for UNAVAILABLE and throw IllegalStateException.
  *   Using StructuredTaskScope (no subclassing) feels weird because you must decide to use either the `<>` diamond operator to allow any types or define a type T for restricting subtasks (makes you wonder if you are using it correctly). Whereas, both ShutdownOnFailure and ShutdownOnSuccess just feel right to use.
  *   In IntelliJ the Javadoc of StructuredTaskScope doesn?t seem to properly format and makes it very difficult to read (probably an issue with IntelliJ).
  *   Blocking IO is not interruptible and this can cause confusion when the scope won?t close in a timely manner even though something may have already thrown an exception (probably falls under the Non-Goal of thread cancellation mechanism). e.g. 2 calls to fork one reading a short file and the other reading an long file, short one fails, if I don?t do something to close the long file stream I will read the whole thing (making ShutdownOnFailure not really live up to its name).

I love that StructuredTaskScope interrupts threads on close/shutdown (it allows some short-circuiting that I struggled with when using Executors.newVirtualThreadPerTaskExecutor()). Here is my new favorite code snippet using StructuredTaskScope:

#!java --source 23 --enable-preview

import java.io.*;
import java.util.concurrent.*;
import java.util.function.Supplier;

void main() throws ExecutionException, InterruptedException, IOException {
  System.out.println(process("Hello, World!", "cat"));
}

ProcessResult process(String input, String... command)
    throws ExecutionException, InterruptedException, IOException {
  try (var scope = new StructuredTaskScope.ShutdownOnFailure()) {
    var process = new ProcessBuilder(command).start();

    scope.fork(write(process::getOutputStream, input));
    var stdout = scope.fork(read(process::getInputStream));
    var stderr = scope.fork(read(process::getErrorStream));
    var exitValue = scope.fork(waitForOrDestroy(process));

    scope.join().throwIfFailed();

    return new ProcessResult(stdout.get(), stderr.get(), exitValue.get());
  }
}

Callable<Void> write(Supplier<OutputStream> outputStreamSupplier, String input) {
  return () -> {
    try (var outputStream = outputStreamSupplier.get()) {
      outputStream.write(input.getBytes());
      return null;
    }
  };
}

Callable<String> read(Supplier<InputStream> inputStreamSupplier) {
  return () -> {
    try (var inputStream = inputStreamSupplier.get()) {
      return new String(inputStream.readAllBytes());
    }
  };
}

Callable<Integer> waitForOrDestroy(Process process) {
  return () -> {
    try {
      return process.waitFor();
    } catch (InterruptedException e) {
      process.destroy();
      throw e;
    }
  };
}

record ProcessResult(String stdout, String stderr, int exitValue) {}

When doing a custom policy, and the subclass defines methods to make 
available the outcome, then you do need to override the join method with 
a covariant return type to make it possible for use sites to make use of 
method invocation chaining. The override will likely just do 
super.join() so shouldn't be too much of a burden, just a bit annoying.

There is an update to the API [1] in the EA builds and draft JEP that 
moves the policy to a side object with a type parameter on STS for the 
return from join. That takes the burden of subclassing off the table.

The code example you included had subtasks that yield results of 
different types. There are cases where the tasks will all return 
something of the same type. Using STS directly is the equivalent of "no 
policy" so closer to the ES.invokeAll in that regard. The default in the 
updated API is changed to work like ShutdownOnFailure in the existing 
API because this is likely the 90% case.

I don't know what this except to note that the API docs have several 
code snippets, maybe the IDE version you are using can't handle this.

Our expectation is that STS will be mostly used for fan out to network 
services. The blocking Socket methods were re-specified in JDK 19 so 
that interrupt closes the Socket, similar to interruptible channels, 
when used in the virtual threads. SocketChannel is an interruptible 
channel so okay there, even when configured blocking.

Your example launches sub-Processes which doesn't have a good story for 
cancellation/interrupt. I hope in time that it will get attention.

Thanks for the response! I should have taken more time to check out the EA build before messaging you. It has everything I wanted and more! All the examples I was messing around with felt great with the latest API.

As for java.lang.Process example, I have reported JDK-8342296<https://bugs.openjdk.org/browse/JDK-8342296> (should be enhancement, not bug) to hopefully create a more reliable paradigm.
  try (var scope = new StructuredTaskScope.open();
      var process = new ProcessBuilder(command).start()) {
    ... // scope.fork to read/write from stdin, stdout, stderr
  }

This still requires `process` to be defined second so that it is closed first. When Process.close() is called it will destroy the child process and the OS will close associated filedescriptors so the VirtualThreads can unblock to read EOF.

Is there anything else I could be doing to help push the story of Process cancellation/interruption? i.e. can we have the Process to expose getInputChannel/getOutputChannel/getErrorChannel backed by FileChannel and make similar changes to FileChannel as SocketChannel so that interrupting a virtual thread blocked on a read/write will unpark the thread.


P.S. Alan, I enjoyed watching your talk on the Devoxx/Java Youtube channels. It?s what inspired me to reach out.

Thanks for taking the time to write a mail on your experiences.

Things that felt strange or annoying:

  *   When subclassing StructuredTaskScope I always have to @Override `join` and `joinUntil` to return my subclass type to provide a fluent api.

When doing a custom policy, and the subclass defines methods to make available the outcome, then you do need to override the join method with a covariant return type to make it possible for use sites to make use of method invocation chaining. The override will likely just do super.join() so shouldn't be too much of a burden, just a bit annoying.

There is an update to the API [1] in the EA builds and draft JEP that moves the policy to a side object with a type parameter on STS for the return from join. That takes the burden of subclassing off the table.





  *   When subclassing StructuredTaskScope @Override `handleComplete` I find myself wanting to write a switch expression on Subtask#state(), but if I do, I always need to have a case for UNAVAILABLE and throw IllegalStateException.
  *   Using StructuredTaskScope (no subclassing) feels weird because you must decide to use either the `<>` diamond operator to allow any types or define a type T for restricting subtasks (makes you wonder if you are using it correctly). Whereas, both ShutdownOnFailure and ShutdownOnSuccess just feel right to use.
The code example you included had subtasks that yield results of different types. There are cases where the tasks will all return something of the same type. Using STS directly is the equivalent of "no policy" so closer to the ES.invokeAll in that regard. The default in the updated API is changed to work like ShutdownOnFailure in the existing API because this is likely the 90% case.




  *
  *   In IntelliJ the Javadoc of StructuredTaskScope doesn?t seem to properly format and makes it very difficult to read (probably an issue with IntelliJ).
I don't know what this except to note that the API docs have several code snippets, maybe the IDE version you are using can't handle this.





  *   Blocking IO is not interruptible and this can cause confusion when the scope won?t close in a timely manner even though something may have already thrown an exception (probably falls under the Non-Goal of thread cancellation mechanism). e.g. 2 calls to fork one reading a short file and the other reading an long file, short one fails, if I don?t do something to close the long file stream I will read the whole thing (making ShutdownOnFailure not really live up to its name).

Our expectation is that STS will be mostly used for fan out to network services. The blocking Socket methods were re-specified in JDK 19 so that interrupt closes the Socket, similar to interruptible channels, when used in the virtual threads. SocketChannel is an interruptible channel so okay there, even when configured blocking.

Your example launches sub-Processes which doesn't have a good story for cancellation/interrupt. I hope in time that it will get attention.

-Alan

Subject: RFR: RISC-V: Avoid return misprediction

This is a small enhancement for the loom riscv-specifc changes. This fixes a return misprediction performance issue which was recently discovered. See https://github.com/openjdk/jdk/pull/21406 for more details. It simply changes usage of scratch registers prefering `t1` instead of `t0` for jumps and calls, which should not affect basic functionality. This also reverted an unnecessary change previously made in two files  `src/hotspot/cpu/riscv/c2_CodeStubs_riscv.cpp` and `src/hotspot/cpu/riscv/templateTable_riscv.cpp`.

Testing performed on linux-riscv64:
- [x] make test TEST="hotspot_loom jdk_loom" (release build)
- [x] make test TEST="hotspot_loom jdk_loom" TEST_VM_OPTS="-XX:+VerifyStack -XX:+VerifyContinuations" (fastdebug build)

@RealFYang
I programmically looked for t1 uses in Nodes.
The only ones I found missing **cr** (set or kill) was ForwardExceptionjmp and RethrowException.
But compiler don't expect **cr** to survival these i.e. x86 do not kill **cr** in those cases.
Note, maybe some Node(s) was never created, so this is not 100% complete check, but 99%.

@luhenry thanks!

The changes for JEP 491 are currently in review for main line ([pull/21565](https://github.com/openjdk/jdk/pull/21565)). It may be better to re-base your change against that PR or do a follow-up change after it has been integrated.

OK. This change is small and can be applied cleanly to the main-line PR as well. @pchilano : Maybe you can merge this change to main-line PR? Or shall I post comments there? Thanks.

Subject: Feedback on structured concurrency
Message-ID: <CAJLeq8n42AQw81NqTSy8jNcJytrHXBaiF8HeuD6N4t+A5bs-nA@mail.gmail.com>

As we are using structured concurrency in production, we would like to give
some feedback.
We created an adapter
for java.util.concurrent.StructuredTaskScope.ShutdownOnFailure for the
following reasons:

   1. To translate checked exceptions to a RuntimeException. The current
   implementation throws an InterruptedException when calling the join method
   which is a checked exception. This forces the code that uses
   ShutdownOnFailure to handle the exception explicitly or mark their method
   to throw this checked exception.
   2. When calling join, our adapter changes the behaviour from the join
   method to throw exceptions by default by calling throwIfFailed under the
   hood. Our adapter provides an explicit method if a developer doesn't want
   to have an exception thrown.

Remembering to use join().throwIfFailed() instead of join() is a hazard 
that goes away with the API refresh in the early access builds [1]. We 
re hoping to include this update for the next re-preview [2].

ThreadMXBean.dumpAllThreads(), ThreadMXBean.getAllThreadIds(),
ThreadGroup.enumerate(), and Thread.getAllStackTraces() do not return
virtual threads.  See my question at
https://stackoverflow.com/questions/79110874/list-the-virtual-threads-in-java
.

I can see how these APIs would not scale for virtual threads.  What are the
thoughts for an API to list all the virtual threads?  For an in-process
API, would an API that returns Stream<Thread> scale?  I am not sure how an
MXBean API can stream Threads to make it scale.

In my opinion you should not treat VirtualThread differently than any other
class, for example ArrayList. Like ArrayList, JVM may have hundreds
of thousands of VirtualThread's and in every second thousands can be
created and thousands can be garbage collected.
In my opinion you cannot expect that JVM will give you all virtual threads.
(Compared to platform threads, platform thread count is usually limited to
hundreds). Like for ArrayList, you can take heap dump

Anyway, JVM keeps all virtual threads
in jdk.internal.vm.ThreadContainers.RootContainer.TrackingRootContainer#VTHREADS.
But I hope it is dead end and will be abandoned

Right, the cited APIs were all re-specified in JDK 19 to only enumerate 
platform threads. This extends to JVMTI APIs and the debugger wire 
protocol too. None of these APIs scale, e.g. ThreadMXBean requires a 
mapping of thread identifier to Thread for local use, getting a snapshot 
of all virtual Thread objects in the heap would require a stop-the-world 
and/or walking the heap.

There are lots of ideas for expanding the serviceability APIs in this 
area. Some of these will require significant changes to the debugger 
protocol and agent.? In the mean-time, the only serviceability that 
include all threads are the heap dump and the thread dump taken with 
jcmd Thread.dump_to_file.

Subject: New candidate JEP: 491: Synchronize Virtual Threads without Pinning
Message-ID: <CANdi0zF1ZaD+FOY=F0jFqKJOeAk6Nrv0BjEeS=Ke7XahS3SjJQ@mail.gmail.com>

Hello,
I work on the Java Agent team at Contrast Security. Our agent has to track
security-relevant data/contexts across threads (including virtual threads).
When a thread changes contexts, it pulls from a ConcurrentReferenceHashMap
of contexts. On Java 21 with virtual threads, we were getting a deadlock
with ConcurrentReferenceHashMap as it uses ReetrantLock. The only way we
found to fix this deadlock was to change to use synchronized instead of
ReetrantLock in order to pin the current virtual thread to a platform
thread until our context switching completed. This was likely because we
instrument the ForkJoinPool to track context switches. Since virtual
threads are built on ForkJoinPool, we need to make sure our instrumentation
always executes on a platform thread to avoid deadlocks. I believe our
agent will always need to be able to pin threads while context switching.
Other Java agents might need to as well. Changing synchronized to avoid
pinning seems like a good idea overall for the JVM, but I think it would be
good if this JEP also provides an API to pin and unpin threads (possibly on
the JDK Instrumentation object so it's only for agents). Otherwise we'll
need to find some other hacky solution (if one even exists) or we won't be
able to support security analysis with virtual threads in whichever JVM
version implements JEP 491.

If I read this correctly, you are instrumenting critical JDK code to 
call out to effectively arbitrary Java code. I doubt this will be 
reliable. In addition to the deadlock issue you mention, you will 
shortly need to deal with the interaction with FJP being in the context 
of the virtual thread, not its carrier, when one virtual threads unparks 
another. There are also subtle issues with arbitrary Java code consuming 
the parking permit and leading to lost wakeup issues.

There has been some prototype exploration into JVMTI events to allow 
callbacks in native agents (not Java agents) execute at scheduling 
points. This is the closest thing that comes to mind when reading your mail.

Reading your mail again, I'm puzzled as to why you are doing this. A 
virtual thread and its carrier are separate threads. What security 
relevant data are you tracking?

We track untrusted data moving to different threads. Oversimplified example:

```
final String param = httpRequest.getParam("foo");

new Thread(() -> {
    // Vulnerable to SQL Injection.
    sqlConnection.prepareCall("SELECT * FROM foo WHERE bar='" + param +
"'");

    // ...
}).start();

Thread.startVirtualThread(() -> {
    // Vulnerable to SQL Injection.
    sqlConnection.prepareCall("SELECT * FROM foo WHERE bar='" + param +
"'");

    // ...
});
```

We need to detect both of these cases of SQL Injection so we store a
context of untrusted data to keep track of how that data moves between
threads.

Okay, but this is just capturing and using in two threads, it shouldn't 
require instrumenting scheduling points.
