8235305: Corrupted oops embedded in nmethods due to parallel modification during optional evacuation

During optional evacuation it is possible that G1 modifies oops embedded in nmethods in parallel. One source are oop* gathered by a previous evacuation phase in the optional roots, the other the region's strong code roots list. Since these oops may be unaligned on x64, this can result in them being corrupted. The fix is to not gather embedded oops in the optional roots list as the strong code roots list contains them already.

8235305: Corrupted oops embedded in nmethods due to parallel modification during optional evacuation

During optional evacuation it is possible that G1 modifies oops embedded in nmethods in parallel. One source are oop* gathered by a previous evacuation phase in the optional roots, the other the region's strong code roots list. Since these oops may be unaligned on x64, this can result in them being corrupted. The fix is to not gather embedded oops in the optional roots list as the strong code roots list contains them already.

Is ?lightweight? descriptive enough if we are essentially discerning pre-emptive threads from cooperative ones, or kernel ones from user land ones? Would it therefore be more useful to introduce a hierarchy reflecting the scheduling nature nature of a thread?

Also, as a term, ?lightweight? tends to survive only until something more lightweight comes along.

Thanks Alan. I missed that particular ?thread?. ;-)

?Virtual thread? is better, but I?m still wondering if ?cooperative thread? vs ?preemptive thread? is more descriptive...

I also like how there?s no hierarchy of thread types also. 

Naming is hard. :-)

Virtual threads aren?t cooperative, but preemptive.?While the default virtual thread scheduler probably won't use time-slice?
preemption (as it?s probably unnecessary and unhelpful), other custom?schedulers could, and in any event preemptive != time-sharing.
See https://en.wikipedia.org/wiki/Preemption_(computing)#Preemptive_multitasking :

Are there any current or planned constructs in Java that allow blocking on
multiple streams of events simultaneously, similar to the `select`
statement in Go? I realize that technically speaking this is probably
orthogonal to Loom, but it seems like an important capability in order to
get the most out of the blocking, imperative thread abstraction that Loom
is fundamentally about.

That?s easy to answer, in a literal sense:  No, Java is not likely
ever to have a bespoke ?select? syntax, just as it is not likely ever
to have the SQL-like keywords of LINQ, or the COMMON statement
of Fortran or the PICTURE statement of Cobol.  Java invests
complexity in API richness, so that the existing language constructs,
combined with well-designed APIs, produce readability without
the need for a long catalog of special-purpose syntaxes.

In a less literal, but more useful sense:  Yes, Java is likely to have
a notation which covers the same ground as  ?select?.  If I had to
guess, I?d say that when pattern-matching switches go live, somebody
will build APIs which use such switches much as Go uses its special
?select? statement.  This ?notation? (not ?syntax?) is mostly API,
with careful use of syntax.

Yes, the syntax of Java does expand, but almost never for single
purposes; it always expands in ways that serve many APIs, including
those not yet conceived of.  *That* is how we grow a language.

https://www.cs.virginia.edu/~evans/cs655/readings/steele.pdf
https://www.youtube.com/watch?v=_ahvzDzKdB0

A less general, perhaps more useful answer can be obtained by
looking at the existing API points for threads and channels, and
asking ?Does Loom support these with good quality??  And also,
?What is the best notation for using these API points, in today?s
Java syntax??  And finally, after those questions are answered,
?Which proposals for future syntax changes are likely to those
API usages more readable??  And with vanishing rarity, ?Are we
missing a future syntax proposal that would make this and many
other notations markedly clearer and more robust??  None of
these questions is answered by ?Hey, we forgot to add Go?s select
syntax!?

I've lurked on these mailing lists for a long time, and I promise this is
not one of those "why don't you just" questions. I make reference to Go's
`select` statement only as a convenient analogy for the kind of
"multi-block" functionality I'm thinking about. What is interesting to me
about this problem is that I don't see a way to implement any kind of
functionality like this, *except on top of asynchronous code*. I'm not
aware of any primitives in Java that you could use to build multiplexed
blocking operations, such as blocking on multiple `BlockingQueue`
instances. I'm curious to hear what the experts think of this problem.

I was about to say that.

The benefit of select is not syntactic. It is the non-deterministic choice.
In the case of Go it is a bunch of channels. In case of Java there is nio
API for epoll, but no such thing for queues. Being able to inspect which
queues are ready, is something asynchronous code can do, but blocking code
can't.

Good clarification.  And you didn?t say ?syntax? in your first note, you said
?construct?.  I?m glad see you didn?t mean ?syntax? but rather something like
what I called ?notation? in my reply.

> What is interesting to me about this problem is that I don't see a way to implement any kind of functionality like this, *except on top of asynchronous code*. I'm not aware of any primitives in Java that you could use to build multiplexed blocking operations, such as blocking on multiple `BlockingQueue` instances. I'm curious to hear what the experts think of this problem.

There are such primitives in Java, which apply to suitably
conditioned sets of blocking operations.  They don?t (at
present) cover all the blocking channel APIs, just a few.

Perhaps you haven't seen java.nio.channels.Selector or
CompletableFuture.html::anyOf, or else you don?t count
them as suitable foundations for blocking operations.
Either way, that is the sort of starting point we were at
before Loom.

I?ll let the Loom team respond further, after I point
out two more things:  The Loom team is refactoring
the internals of the JDK concurrency APIs to be fiber-friendly
which means scheduler-friendly, so you can expect
to see robust selection infrastructure along with Loom.
And, to close the loop on your original request, such
API points (which will be like the ones I mentioned
but surely better) will be the primitives on top of which
a switch-friendly wrapper API (with a future version of
switch) would create a notation competitive with Go?s
select statement.

Yes. We've been contemplating adding to java.util.concurrent a
Loom-friendly channel-like component with select-like capabilities. I
hope to write more about this in the coming months when it gets concrete
enough to ask for feedback. For now: the most likely name is "Carrier",
to distinguish from other channels and queues in Java.

As others have noted, there's not likely to be special syntax, but the
new pattern-match constructs should serve well. As in:
switch(selector.receive()) { case Request r -> service(r); ... }

What do you mean "multiple streams of events"? Merging them, zipping them,
combining them?

> blocking on multiple `BlockingQueue`

My impression about Loom is that most operators, especially multi-valued
streams, are DIY. So blocking on multiple queues means you block on each in
its own virtual thread, then enqueue the object on another blocking queue
which you block for on the end consumer virtual thread. The complication
is, as with Flow.Publishers, when the number of input queues is dynamic,
how to propagate errors and indicate termination.

It's not the same as blocking on N queues. That consumes N elements.

Select consumes one element from some queue. It's like blocking on N
queues, then push back N-1 elements before anyone else gets anything from
those queues.

I like the MessageBox/Mailbox metaphor given that it seems conceptually similar to Erlang.

So the actual equivalent using BlockingQueues would be:

Modify offer and poll non-blocking methods:

Either<T,CompletionStage<BlockingQueue<T>>> poll()

So that instead of value vs null you get a value or CompletionStage that is
completed when the queue is no longer empty. (Similar for offer - either
None, or a CompletionStage that is completed when the queue is no longer
full)

It's easy to see how such a primitive implements both blocking and
non-blocking behaviour: if you want to wait, you attach to the
CompletionStage; if you don't, you are non-blocking.

Now, given a list of such queues,

0. Construct a CompletableFuture
1. Shuffle
2. Fold that either finds a queue that returns a value and completes the
future with it, or constructs a chain combined with runAfterEither

3. runAfterEither runnable goes to step 1 (can bias towards the queue that
fired the non-empty first).

Subject: Virtual threads in existing FJP logic
Message-ID: <CAJi8+g7QaEQJmUTgp6PFUUwf2zNkRV1eq26hs9GZ5gSwQ0ZY1w@mail.gmail.com>

Hi everybody,

Marc and I from the JUnit team are exploring ways how to
integrate virtual threads into the Jupiter test engine. Today
we're using a FJP to enable parallel test execution.

Find the implementation here [0], where at end of the source
file, you'll see our custom ForkJoinWorkerThreadFactory and
the custom ForkJoinWorkerThread implementation.

My idea was to "simply" configure those custom classes to
create virtual threads. Is this possible? If not, we might
resort to add a virtual thread based implementation of the
HierarchicalTestExecutorService interface.

Cheers,
Christian

Hi Christian,

I believe it should be possible and doable. The Worker Thread Facrory,
while creating Threads, should simply create Virtual Threads instead of
java.lang.Threads.

Sincerely,
MNK

Hi Nawazish,

the issue I see is that the ForkJoinWorkerThreadFactory declares
a method newThread with ForkJoinWorkerThread as the return type.
That ForkJoinWorkerThread already extends java.lang.Thread, see
[0] for details. The API of ForkJoinWorkerThread doesn't allow
setting a virtual flag nor does the Thread.Builder help in this regard.

Cheers,
Christian

FYI, we took the second road and started with
VirtualThreadHierarchicalTestExecutorService [0].
Got virtual threads running on our first try.

So glad, that "virtual threads are threads".

Cheers,

Hi Christian.

I?m not sure I understand. You want to use virtual threads as
FJP *workers*? If so, why??

It is never a good idea to pool virtual threads, and FJP is all about?
pooling. Of course, you could always set your FJP as the *scheduler*
for your virtual threads.

Ron

Yes. That was our first attempt to get virtual threads working
with the existing ecosystem -- based on an obvious lack of
understanding paired with gettting things done "quick and dirty".

Understood and already implemented our spike based on
that idea: [0] ... works like a charm, so far. Looking forward
seeing Loom being integrated to OpenJDK's master branch.

I presume that the public `setParent()` method is there as a quick hack 
for purposes of prototyping, and not intended as an API proposal?

It's not public and I assume it just to get the PoC working. Threads 
usually inherit at Thread creation time (rather than start time which 
can be problematic sometimes when an unstarted Thread is passed around). 
In any case, my reading of this PoC is that its for one scenario/usage 
only as it doesn't prevent the scoped binding in the parent from being 
closed (or mutated?) and I assume it doesn't work with thread pools 
where the setup/tear-down is around the task rather than the thread. 
This area will likely require many rounds of exploration and prototyping.

Subject: Temporal coupling in Fibers and Fibers vs State Machines.
Message-ID: <CAGveQrv7yhJhXG1uYWvFy4-7JNOOO=LwLqSWuFGry8Bx=P2ZJQ@mail.gmail.com>

Hi All,

I have been following Project Loom for quite some time now and I find it
really exciting.
This is my first post in the mailing list.

I went through the following twitter discussion -
https://twitter.com/rafaelcodes/status/1176229314112741377
However I could not understand the final gist/conclusion of the discussion.

1. Here In the discussion Martin Thompson had the view that Fibers don't
compose and cannot escape temporal coupling.
He also advocated about the use of explicit state machines instead of
Fibers.
https://twitter.com/mjpt777/status/1176231250308325376

2. Vaughn Vernon had opinions around the Java memory model and the
complexity of the effects of predictive execution.
https://twitter.com/VaughnVernon/status/1176299015849136128


Could someone explain what were the concerns and suggestions they expressed
and how Fibers handle said concerns.

It would be great if someone could suggest some resources to better
understand above twitter discussion.


Thanks,
Rahul

Hi.

I don?t think I really understand what the concerns are, and believe they might  
be tied to a misunderstanding of Loom?s goals and design.

Anyone who has concerns is welcome to explain them here, without character-count limits.

Rafael's concerns are mostly related how the functional and declarative
nature of the reactive libraries are difficult to learn for some people.
Yet, these people happily code in SQL and use Java Streams. Maybe it's time
to go back to reading database files with InputStream and use for loops as
well.

Martin's concerns are, if by composition he means what I think he means, if
you could set up pieces of computation and functionality and combine them
into larger components. If so, these components can have state and those
state could change in response to stimuli from other components. Reactive
is one of such approach that has individual pieces - operators chained up
on a dataflow have internal state tracking when and how their peers can
send data and commands to each other. Loom's, and Kotlin's Coroutines
instead say you compose via the source code itself, by writing larger and
larger methods encompassing a lot of imperative operations. If you have
such a method, but for some uses need some retry code, you may be out of
luck and have to code yet another set of methods to include that
functionality.

Vaughn's concerns are that there aren't many helping hands with Fibers and
concurrency. In fact, you have to consider the Java Memory Model again the
moment two routines in separate fibers have to communicate: blocking
structures, atomics, locks and their effects on visibility. In reactive,
from an user's perspective, you don't have to worry about most of these as
the libraries can hide many of the intricacies of the JMM and provide you
with an API and callback surface. Want to create an item and hand it over
to another thread for processing? There are operators for that and you have
only to specify how to create the item, what thread it should end up and
what processing there should be for it. Want to generate many items?
Replace the front of the flow and the rest will still be the same.

Also note that Loom's sales pitch has shifted over the years. It started as
the solution that will outperform reactive and having users code in easy to
understand imperative fashion as the JVM will do the heavy lifting behind
the scenes. However, we have pointed out that a) suspension is more costly
and may dominate the overheads, b) composition (see above) is limited so
people, individually and over and over, may end up with DIY solutions and
c) you have to make sure locks/blocking happen in a virtual thread for
which you may have to inject virtual thread-based executors all over the
place.

I believe the concerns are more that things like "CompletableFutures" are hard to intuitively
compose correctly.

For example, think of a graph of Futures.  Now imagine you want to conditionally traverse the graph
based on node the values returned by each future and cancel the rest based on some condition.

With CompletableFutures and traditional threads, that's really difficult without introducing a lot of blocking
on some thread.  In fact, it's pretty much impossible using the composition methods available.  You are
forced to call `.join()`.  This is isn't so bad with loom backed completable future but it is a killer for the standard FJP.

On the flip side, async/await syntax handles this sort of thing pretty much right out of the box. The awaits all
allow the current thread to go do something else useful and, as a bonus, are pretty easy to read.  The
downside is the colored function problem.

I believe that is where the composition statement comes into play.  Futures and promises are hard
to compose correctly.  They end up looking ugly and hard to read.  Loom helps here, but ultimately,
it means you have to start caring at a function level "Is this running on a fiber pool or a regular pool".
If the answer is a regular pool, you run serious risks calling .join() if your code is also executing within the same pool.

Just my two cents.

I still like the loom approach simply because it eliminates the colored function problem without adding
extra cognitive burden.

I am not sure what Martin?s and Vaughn?s concerns, as you explain them,
have much to do with Loom, though.?

You want to write hand-roll your own state-machines, rather than use the?
state-machine abstraction provided by the platform and known to all tool,?
i.e. the method ? go ahead. But people who do like organising code into?
subroutines have suffered from a scalability issue that Loom intends to resolve.

JMM concerns apply to anything concurrent, and while Loom doesn?t make
them go away, it also doesn?t solve global warming. I think there is some
misunderstanding there about what Loom is. Things generally addressed by
reactive frameworks are, however, also addressed by Loom. The composition
offered by Loom is any composition offered by the Java language (or any other
Java-platform language), and it is easy to show it is superior to the limited
composition offered by the reactive style (it subsumes it, and the compositon
it offers is essentially that of process-calculi ? the state-of-the-art algebraic,
compositional formalisations of concurrency).

As to performance concerns, what Loom has always been about is achieving
the same (or virtually the same) scalability benefits that the reactive style
enjoys to a programming style that?s more harmonious with the Java platform.
I do not why suspension should dominate costs (although your wording is
a bit unclear to me; if suspension is your only overhead, then however cheap
it is, it will dominate). The cost of suspension has dropped by a factor of about
ten recently (with a flag that?s currently disabled by default), but I would be very?
interested in benchmarks that show that show it is any cause for concern.

My feeling is, therefore, that those concerns, as you expressed them, do not
apply to Loom as I see it, so I think there is some broken communication.

I don?t think it does.

Every abstraction, pretty much by definition, hides some implementation details.
Java?s Map and List interfaces hide the cost of their operations; parallel streams
hide the number of processors, and threads hide the implementation of a scheduler.

If you?re writing a real-time application you might care a great deal about
the implementation of the scheduler ? whether it handles priority inversion, whether
it works in a strict round-robin fashion etc.. Other times, you might care less.
But guess what? Reactive frameworks *also* hide the implementation of the scheduler.
IIRC, the Reactive Streams specification allows the scheduler to schedule all operations
onto a single thread, and make all operations blocking. So you need to care about
the implementation of the scheduler to the same extent, whether you?re writing?
synchronous or asynchronous code. Just as you pick a scheduler for your asynchronous
code, you can pick one for your synchronous code.

So I don?t see how threads make caring about scheduling more or less important. They
just offer a different way of expressing the same computation, a way that happens to
be more in line with how the Java platform ? that?s largely organised around the thread
abstraction ? is designed.

The problem with all forms of async is that they are bolted on to the
language.

For loop is great. Lexical scopes are there to control visibility and
lifespan of variables. Java language guarantees which statements are
reachable and which are not and when.

Concurrency issues are not limited to JMM. It is a general problem of
knowing what gets executed when, and which of the ordering is intentional,
and which is accidental consequence of the implementation (how do you
refactor in order-preserving, bug-compatible way). Yes, when using threads
these problems reduce pretty much to the cases JMM calls out. With reactive
and futures the stretches of code where program order applies, are much
much shorter.

The biggest problem with futures and reactive is the absence of those basic
guarantees that the language provides - it becomes an implementation detail.

Even such simple things as "will this piece of code be executed" are no
longer something the language semantics can guarantee - if the future is
not completed because of a bug in the code, you have code behaving like
non-termination. Same with reactive. "Will this code be executed once and
only once" is no longer something the language semantics can guarantee. If
the implementation of a Publisher is broken, there is no defense, you are
going to receive out of order events, arbitrary number of times.

Not so with for loops. There are easily comprehensible semantics of what is
executed when, how to break the loop, what happens to errors.

My point was more that the safe actions on a CompletableFuture are different depending on the underlying ExecutorService, particular with Loom.

CompletableFuture#join or Future#get is only safe if you do that join from a thread in a different pool than the one the Future runs on.

It often becomes a style rule to simply say "Never call CompletableFuture#join".  That calculus changes significantly with Loom.
Join is suddenly perfectly fine  (if not preferred!) over more complex then* methods.  It's arguably a lot more readable.

If I have some method which does a lot of future wrangling, how I implement it (and even the return type!) will change drastically if
I think those futures are on an UnboundedExecutorService of virtual threads vs a fixed thread pool. (The latter being a bunch of then* functions returning a CompletableFuture).

This is where it might help to expose some of that information at the type system.  It could be nice if UnboundedExecutorService returned a UnboundedFuture or... whatever (I'm terrible at names).

IDK, though, maybe it's enough to just inject an UnboundedExecutorService where the futures are made.
I mean, ultimately, we have things like "ManagedBlocker" which only really operates if the pool it runs on is a FJP.  That?s somewhat the same issue.

I don?t think it does.

Every abstraction, pretty much by definition, hides some implementation details.
Java?s Map and List interfaces hide the cost of their operations; parallel streams hide the number of processors, and threads hide the implementation of a scheduler.

If you?re writing a real-time application you might care a great deal about the implementation of the scheduler ? whether it handles priority inversion, whether it works in a strict round-robin fashion etc.. Other times, you might care less.
But guess what? Reactive frameworks *also* hide the implementation of the scheduler.
IIRC, the Reactive Streams specification allows the scheduler to schedule all operations onto a single thread, and make all operations blocking. So you need to care about the implementation of the scheduler to the same extent, whether you?re writing synchronous or asynchronous code. Just as you pick a scheduler for your asynchronous code, you can pick one for your synchronous code.

So I don?t see how threads make caring about scheduling more or less important. They just offer a different way of expressing the same computation, a way that happens to be more in line with how the Java platform ? that?s largely organised around the thread abstraction ? is designed.

Calling Future.get and CF.join is safe only if you can prove they are

Almost anything you do in a concurrent context depends on the scheduler. Whether
blocking on *anything* will ever complete, or equivalently, whether a task?
submitted for execution will ever run, depends on the fairness of the scheduler.

In fact, on operating systems that do time-slice-based preemption, any piece
of code can stop running at any time and never continue. So when we write a;b
and assume that b will run if a terminates, we rely on an implicit assumption?
that the scheduler is fair.

> CompletableFuture#join or Future#get is only safe if you do that join from a thread in a different pool than the one the Future runs on.

I am not familiar with this rule. I believe that CompletableFuture.join,
when running on FJP, will help execute tasks. I believe you are referring
to the possibility of a self-deadlock, but this, too, has implicit
assumptions. Depending on the implementation of the future, as well as of the?
scheduler, any blocking operation could potentially never terminate.

Not just self-reference.

When talking about Future.get, one should not say "it blocks just one
Thread [we can afford it]". Instead, say "it blocks one Thread at a time".
It becomes obvious that such use can block an arbitrary number of threads,
so thread pools with upper bound on size will eventually deadlock.

Subject: Question regarding doYield & doContinue 
Message-ID: <7306449B-57BD-47D2-8C07-06370FA01A8F@uni-duesseldorf.de>

Dear all,

one of my students is studying loom during his Bacheloer thesis and tries to understand how loom works. Can someone give us a hint where we find the implementation of doYield & doContinue (both intrinsic functions)?

These are the functions, in
src/java.base/share/classes/java/lang/Continuation.java

@HotSpotIntrinsicCandidate
private void doContinue() { throw new Error("Intrinsic not installed"); };

@HotSpotIntrinsicCandidate
private static int doYield(int scopes) { throw new Error("Intrinsic not installed"); };


Thank you

Michael

Hi!

For x86 they are generated in stubGenerator_x86_64.cpp.
generate_cont_doYield and generate_cont_thaw.

?
Not necessarily. It depends on the implementation of both the future and the
scheduler. For example, Future.get could itself call back into the scheduler
to run tasks while waiting. I believe this is what CompletableFuture does
on a ForkJoinPool. In any event, whether *any* instruction ? not just?
Future.get ? is ever completed is entirely dependent on scheduler?
implementation details.

It is true that Loom allows a user to provide their own scheduler for j.l.Threads,
something that has so far been left for the operating system (although?
users could still write implementations of j.u.c.Future), but I think that the?
great care required in writing a scheduler is the responsibility of the?
implementer of the scheduler (and of the Future), rather than that of the?
abstraction, that is meant to hide such scheduling details. Authors of such?
important, low-level constructs should document their proper use.

So you need to care about the implementation of the scheduler to the same extent, whether you?re writing synchronous or asynchronous code.

Hi D?vid,

Thanks for the explanation.

I have a little experience with Kotlin Coroutines and you are right in
saying that composition have to be taken care in the source code itself. It
could be argued that reactive APIs are much more easier to use in that
sense.

It is also true that when using reactive APIs, Developers don?t have to
deal with low level constructs like atomics, locks, etc. This doesn't look
same in case of virtual threads, Virtual threads looks pretty much same as
normal threads when dealing with shared resources. correct me if I got it
wrong here.

About the sales pitch of loom, I can see the same thing. When I started
following loom few years back, it was proposed as a solution where you can
write imperative code and get the performance on par with reactive code. It
actually felt like JVM will do the heavy lifting and API users won't have
to deal with it. It is really hard to get concurrency right in Java and
even after loom it looks like that users will have to rely on DIY solutions
or third party libraries to get things right.

Thanks,
Rahul

This is a false impression. Reactive does not offer thread safety, nor does
it eliminate concurrency.

What it does ensure, is it forces you to use a different style of
expressing a solution. It forces you to share less state, because it is
difficult to express scope of things.

So you have no locks, but not because state modification becomes magically
safe. It is because you share less. Maybe you pass more along the pipeline.

Doing away with the locks is not free either. What would have been a
synchronized block, becomes a pipeline that needs to be executed by a
single thread at a time.

Here is an article that goes into some depth of pros and cons of fibers: 
https://blog.softwaremill.com/will-project-loom-obliterate-java-futures-fb1a28508232

I guess right now, without the structured concurrency API, it really 
isn't so easy to see the promise of Loom. The "let's make fibers look 
like threads" approach might add to the confusion.

Cheers,

Cay

Loom adds a lightweight implementation of threads, similar to how ArrayList and
LinkedList are two implementations of List with different performance characteristics.
True, often a difference in implementation can change coding practices. After all,
people avoid blocking threads not because of the abstraction but because of the?
implementation, but I am not sure what kind of confusion this causes.
I cannot see in what way, other than implementation, a fiber is different from a thread,
so I am not sure what the two concepts you?d like to see separated are. Could
you explain?

As to the "promise of Loom", let me try to put it like this: think of all the code patterns,?
libraries etc. made to avoid creating and blocking threads. Now think what it means if
creating and blocking a thread is cheap.

Hi Ron,

when I teach or write about concurrent programming, it seems to me that 
programmers tend to be confused about threads and tasks. I try to tell 
them to focus on tasks. Threads and fibers/virtual threads are just a 
mechanism to run tasks. Most programmers should just defer to some 
machinery that maps tasks to whatever is required to run them. With 
fibers/virtual threads, the situation is much brighter than before--one 
can now map lots of tasks that block a lot.

So, my point is that I am long past "blocking is cheap". It's marvelous 
that Loom makes it so, and I appreciate that this is quite a feat of 
engineering.

My hope is that Loom will provide an API for running those tasks in a 
way that makes sense to application developers. The classic thread API 
is not exactly developer friendly, and that's what people see now when 
they investigate Loom.

Perhaps ExecutorService.invokeAll and ExecutorService.invokeAny, when 
used with fibers, could be sufficient for structured concurrency. But it 
appears to be an awkward API.

A few iterations ago, you had a more compelling API, and I look forward 
to seeing more work on that.

There will always be the state machine enthusiasts, but if Loom could 
nail the equivalent of invokeAll and invokeAny, with cancellations, 
durations/timeouts, and resource cleanup, that would take care of a lot 
of use cases.

Cheers,

Cay

I assume you are mean the FiberScope prototype that we had last year. 
Here's roughly the same with ExecutorService in the current prototype:

 ??????? ThreadFactory factory = Thread.builder().virtual().factory();
 ??????? Instant deadline = Instant.now().plusSeconds(20);
 ??????? try (var executor = 
Executors.newUnboundedExecutor(factory).withDeadline(deadline)) {
 ??????????? :
 ??????????? result = executor.invokeAny(tasks);
 ??????? }

invokeAny isn't too bad here as it will cancel any tasks that haven't 
completed when there is result. We hope to have prototypes soon that 
improve on this, also better integration with completable futures and 
streams. So yes, your point that the API surface looks a bit bare if you 
only look at the Thread API. Most of the effort on this project to date 
has been on the foundation work.

-Alan

This test sometimes failed due to never hitting the breakpoint in Continuation.run(). This is because if every vthread is mounted on a carrier thread, you may never see another call to Continuation.run(). Allow at most 2 carrier threads for the 3 vthreads.

The builds at the Project Loom EA builds page [1] have been refreshed. 
The updated build has several stability fixes and other changes that 
have been pushed in the last month or so. The API Javadoc has been 
refreshed too. Ron's mail of Dec 19 [2] has the details including the VM 
option to use the new continuations implementation (it's not the default 
yet) and the system properties that can be used for configuration and 
debugging.

Hi,

thanks for the update. My smoke tests produced a SIGSEGV:
https://github.com/sormuras/junit5-looming/runs/471925895

Also, the initial section at https://jdk.java.net/loom/ still reads:

_Warning: This build is based on an incomplete version of JDK 14._

Should be JDK 15, right?

Thanks, I see this is +UseContinuationChunks so it's "new 
implementation" that is enabled by default yet. One of the crashes seems 
to be related to growing a stack, I can't tell if this is OOME related 
or not. We need to do more testing here.

Thanks. Tim has just fixed this page so that it picks up the release 
from the build so should be okay now.
