Yes, that could be useful. I did try your test a few weeks ago and noticed it tickled a storm of uncommon traps so it ended up stressing very specific scenarios. -Alan.

On your website you have this: Continuations are intended as a low-level API, that application authors are not intended to use directly. They will use higher-level constructs built on top of continuations, such as fibers or generators. I took the current EA build for a spin. There is support for Continuations. It solves my use case. I've put an example of how I'd use continuations here: https://gist.github.com/avrecko/a706484e6d7f4963af75a042006f8a4a Basically using Continuations with a SEDA style application. The current EA build implementation looks like it works as expected and solves my use case. Is this something you would _not_ like the users to do? I can see myself using this kind of approach in production very easily without drastic changes to the existing code base and without much surprises. Briefly looking at the code of Continuation. It looks thread safe. So there shouldn't be problems from passing it around and being executing in part from different threads. I do find the Scope argument a bit annoying. I think you could provide an implicit default scope. So unless explicitly specified an implicit - default scope is assumed. In my view you should consider releasing Continuations before Fibers and making Continuations part of public api to be used by developers. I find the current API pretty intuitive to use. Minus the scopes. I like that #run() is final and that Continuation takes Runnable. Makes sense to me.

How is this use case not even *better* with virtual threads? Seems to me? that it will require less code (as the necessary scheduling is already in the JDK), and will be able to run more Java code as it won?t break certain invariants such as the identity of the current thread remaining the same for the duration of a method. I *think* that every use case of continuations that depends on switching threads is better served by virtual threads. The only time I would consider using another continuation-based construct is for constructs that are essentially single threaded, e.g. generators. Am I missing something? For that reason ? virtual threads are easier, less error-prone, and better integrated? with the JDK ? I don?t see us releasing continuations before virtual threads, or even making continuations public in the first release of virtual threads. Unless, of course, some very compelling use case arises. Do you think your use case benefits more? from continuations than from threads? If so, why? BTW, in your case, as in the implementation of virtual thread, a single static final continuation scope seems sufficient.

Ignore the email that I sent you. Thought I clicked reply to all but was reply. No loss as I made some wrong assumptions. I think I get it now.

Just that the OS threads that execute the virtual threads be pooled. I played with the EA build some more. You are reusing existing Thread API for Fibers. So we have a Thread (virtual) that is run by another Thread (non-virtual). Bold move. I think you made the right choice of not having an extra Fiber API. Pretty impressed. For disk IO. How do you intend to do it? Io_uring? I have an existing queue and thread pool that does file io. It also keeps track of read/write speeds. How would I integrate it with virtual threads? So that I can do in a virtual thread something like byte[] data = looksLikeBlockingCallButHeavyLiftingIsDoneOnMyCustomDiskIoThreadPool(); Ah, I think I got it. Virtual park/unpark. Basically LockSupport.park() in the caller and LockSupport.unpark(virtualThread); from the existing thread pool? I tried the code and it looks to work as expected. Very nice. Might I add that this feels more natural than working with Continuation directly. I do have one remark. The IO work is done on an IO thread. And the Virtual Thread is run on the Executor pool. On multi socketed server. The file IO might be done on one socket (calls unpark) and the virtual thread resumes on another socket. There is an unnecessary NUMA memory access. As the IO data that is on the IO thread CPU cache needs to be copied to the other socket. Might be faster to copy the virtual thread stack to the IO socket than to copy the IO data to the other socket. Guess I'd have to do some benchmarks. Thoughts?

I have a few comments: onClose(Runnable): will this allow one handler at most, many handler, or calling multiple times will replace the handler and run the old one? Calling onClose the first time after the carrier was closed runs the Runnable immediately, right? tryReceive(T def): always somewhat trouble to expect a default value of T, perhaps return Optional if T is planned to be non-null. stream(): I presume closing the stream closes the carrier + receive(Consumer): boolean: could allow receiving without making a default T + closeExceptionally(Throwable) : perhaps for both sides? Certainly, one can send a record of T+Throwable one way, but not the other. + onSenderReady(Runnable r): would allow a non-blocking consumer to react to items or sender-side close. + onReceiverReady(Runnable r): would allow a non-blocking producer to react to buffer slots becoming available or receiver-side close. + receiveAsPublisher(Executor): ~ probably should only allow one subscriber and rely on external multicasting ~ without onSenderReady, it has to rely on blocking and thus run on a suspendable thread + sendAsSubscriber(Executor) ~ a full buffer requires suspending so that when a slot becomes available, the upstream can now to send more items ~ without onReceiverReady and blocking on send, I'm not sure how to link cancel to a receiver-side close - depends on how onClose allows registering multiple runnables ~ unbounded capacity <-> unbounded request?

It?d be nice if like the ReadWriteLock, the result of this was a class which has a Send/Receive Carrier? Channel? For example, a similar concept in rust https://doc.rust-lang.org/rust-by-example/std_misc/channels.html Even if you make the Carrier and implementer of a Send/Receive carrier interface, it would make it easier to signal intent from code through the type system (Though, I don?t really like that as much). A bonus of having a Carrier which has a ?getReceivingCarrier? method, or whatever, is that you can eliminate the ?closeForReceiving? type methods. It also could introduce interesting patterns like multiplexing? (IE, having multiple receivers getting the same message) not sure if that is a good idea ??. > One very vague comment: > > This design puts both endpoints on one type, as opposed > to two similar types, like InputStream and OutputStream. > This leads to fewer types and objects (good) but broader ones. > Broader is little less good, since most use points only care > about 1/2 of the methods; the other 1/2 is then noise. > > It would be nice to see an overall policy statement about this. > > ?

I really like where you are going with Loom. I got off on the wrong foot with expecting to see Fiber class. Not seeing it I just went with Continuation. Having played now with both VThread and Continuation. I find working with VThread much more natural. Now I don't see any reason to use Continuation directly except for: I'd still like to be able to have control over scheduling. I think a simple API addition such as: // able to do this while the VThread already did some work but is not yet finished VirtualThread.setScheduler(vt, useThisSchedulerInstread); virtualThread.get/setScheduler. Would do the trick. You are probably rolling your eyes. But looking at the code it doesn't look like a big deal to add API like this. If it would make it easier, could allow for change of scheduler only from within the executing VThread? Another note. I think it would make sense to make VirtualThread class public. I find something like: vt = new VirtualThread(myRunnable); vt.start(); more natural than Thread.builder().virtual().task(myRunnable).start(); in the app code I'd prefer to see VirtualThread over Thread. Just like I prefer to see ArrayList, LinkedList, ImmutableList etc over just List in my code. Gives me a better understanding of the underlying characteristics of the data structure and avoid any surprises.

For now you can do this: ?? var thread = Thread.newThread(Thread.VIRTUAL, task); but expect it to change once there is something better. -Alan From dl at cs.oswego.edu Sat Mar 7 16:29:22 2020 From: dl at cs.oswego.edu (Doug Lea) Date: Sat, 7 Mar 2020 11:29:22 -0500 Subject: draft Carrier API In-Reply-To: <2E3C04E5-ABAD-4C27-B7C9-3411838A7C9D@oracle.com> References: <8c2949c3-e01e-e966-e06a-db9b6eb15c39@cs.oswego.edu> <2E3C04E5-ABAD-4C27-B7C9-3411838A7C9D@oracle.com> Message-ID: <477699d6-7813-c13b-ab5b-4a7d10820173@cs.oswego.edu> Collecting replies/responses, with updated sketches pasted below and at http://gee.cs.oswego.edu/dl/wwwtmp/Carrier.java On 3/6/20 3:56 PM, John Rose wrote: > This design puts both endpoints on one type, as opposed to two > similar types, like InputStream and OutputStream.

The main API design issue here is that there are three (not two) views of a Carrier: the protocol state (closed, empty, etc), sender-side, and receiver-side operations. If you split them, you need at least four interfaces/classes total (one to combine them). Doing this in a way that does not result in nearly all usages needing the combined interface requires other tradeoffs (like declaring some bookkeeping methods public and breaking read-only-ness of base interface). But given the reaction so far, I'm back to thinking this can be done in a way that more people will prefer. (Aside: I've waffled on this many many times, including pre-j.u.c http://gee.cs.oswego.edu/dl/classes/EDU/oswego/cs/dl/util/concurrent/intro.html , and several previous Carrier drafts.)

You get only two ways of interacting with them: try or get blocked indefinitely. A ticket system allows to build nicer things, because essentially you give away a bit of control what to do during the wait. You can switch between try* and blocking after you made the call, choosing when the time to block is more suitable. Alex On Sat, 7 Mar 2020, 16:30 Doug Lea,

Calling closeForReceiving provides more flexibility, but with more cases for users to consider (like stuck senders). But this question invites considering whether even having closeForReceiving would lead to more errors than correct usages. Considering that some of the motivation for Carrier is to reduce opportunities for errors people encounter with hand-made components built from BlockingQueues etc, I think we could remove it. -Doug From alen.vrecko at gmail.com Sun Mar 8 11:56:12 2020 From: alen.vrecko at gmail.com (=?UTF-8?B?QWxlbiBWcmXEjWtv?=) Date: Sun, 8 Mar 2020 12:56:12 +0100 Subject: Continuations before Fibers In-Reply-To: References: Message-ID: I saw the virtual(Executor) method.

In other words, you'd sometimes like Carrier to act more like ExecutorService (obtaining a Future or something like it on submission).

Right; thanks especially for the questions about what confused programmers who aren't used to dealing with half-closed states might do. Probably best to stop using "close" except for full close.

The use of the same term is lost on me. In networking, half closed socket is really a fully closed pipe in a duplex. Here it is more of half closed singular pipe - closing one end of the same pipe, just from different ends. So some of the states that become possible are really strange. Calling it finish is better, but perhaps some confusion about possibly interpreting it as an imperative instruction is still there. (Telling the sender to "Finish!") My understanding that the intention is to capture Carrier transitioning like so: sending and receiving -> sending complete, receiver can only drain buffered items, reject future send attempts Or sending and receiving->receiving complete, no more items can be delivered, discard all buffered items and reject future send attempts, reject future attempts to receive Is that right? In the first case receiver needs some hint how many receives are sensible, and if a receive is blocked on empty when sender transitions into the sending done state, the receiver needs a nice way out. Throwing seems like last resort, as typically exceptions indicate transitioning into error states. Returning Optional can be better. Alex On Sun, 8 Mar 2020, 13:37 Doug Lea,

But the type of receive() is going to affect how the code is structured. So I would suggest to spend some time understanding the implications. Was: blocking queue, can be shown to be a co-list. (take() is the destructor removing head) Now: blocking queue with an end, so it becomes a representation of a list (possibly finite). At type level it becomes a union of co-list and a unit. The disjoined unit is a special value returned (eg -1 returned by input stream read), or a mutually exclusive continuation (onNext delivers head vs onComplete delivers unit; fold gets a case for empty list and a function for the case when the list has a head). So it's inevitable the special value emerges in the API. Null, a special exception, empty Optional are probably all you can do in Java. I'd think Optional is the best choice. Null is not safe. Exceptions require quite a bit of boilerplate, which can be annoying, especially given that it doesn't reflect an error state.

The use > of the same term is lost on me. Sorry for the mysterious-sounding answer. "Half-closed" is a design pattern that might never have been written up well but is encountered all the time in concurrent settings under different names. Which makes the naming challenging here. On a little more thought, probably the best choice of terms here are based on those used in ExecutorService, which most people are more familiar with, and where shutdownNow() is a full close; and shutdown() disables submissions and triggers full close when tasks are completed. So: interface CarrierSender extends Carriable { void shutdownSending(); // disable further sending; close when empty // ... } interface Carriable extends AutoCloseable { boolean isClosed(); boolean isShutdownSending(); // true after shutdownSending or close // ... } From dl at cs.oswego.edu Mon Mar 9 12:50:31 2020 From: dl at cs.oswego.edu (Doug Lea) Date: Mon, 9 Mar 2020 08:50:31 -0400 Subject: draft Carrier API In-Reply-To: References: <8c2949c3-e01e-e966-e06a-db9b6eb15c39@cs.oswego.edu> Message-ID: <4ac9508d-a5cd-8874-cd25-f9da1dcb5f8b@cs.oswego.edu> On 3/8/20 6:59 PM, Kasper Nielsen wrote: > Just a quick comment, > I would much prefer if Carrier stuck with using the standard [long > timeout, TimeUnit unit] > used throughout java.util.concurrent.

Just a few questions / clarifications around closing: 1) closeExceptionally - what effect will the passed `cause` Throwable have on other methods, say, like receive? Will the passed `cause` be the cause of the ClosedException ( thrown from a thread blocked in receive )? I assume the `onClose` CF will receive this cause too? 2) ClosedException is an IllegalStateException - Ok. If the OnInterrupt policy is `CLOSE`, then a thread already blocked in a receive invocation will throw ClosedException - same as it would if the carrier was already closed before the receive invocation. Receiving an IllegalStateException for an interrupt seems a little odd to me for this case (but maybe that is ok). Given this, then it is not possible to discern the difference between a carrier that was closed prior to receive or if receive was interrupted. Hmm... maybe this is the point - consistent behavior in the face of async-close?

It features channels and send/receive operations, and the CSP select operation called "alts". The alts op is a plain function (no compiler magic) which non-deterministically chooses the first operation that can proceed, whether it is a channel put or a take. Channel buffers are polymorphic (fixed, sliding and dropping; or no buffer, meaning rendezvous semantics). Channel put returns whether the put succeeded (false if channel is closed). Critically, the channel isClosed predicate is not exposed publicly, as it is hard to use without a TOCTOU bug. Channel take receives the item (which is any reference, including Boolean false!) or receives nil when a channel is closed. There is only a single concrete implementation of a channel, ManyToManyChannel, but the underlying interfaces are split into read/write. When is it useful to use the exception throwing variants of Carrier, rather than trySend/tryReceive? Seems like there is a whole lot of API surface area to deal with channels being closed or closing. >From a receivers point of view, the distinction between shutdown & closed seems arbitrary. You're not done receiving until a buffer (if present) drains. Over the years, I have found from my usage of core.async that the most useful ops around termination are: a sender signaling that they're done, or a receiver abandoning the interaction early. Generally only one side is in charge of closing a channel, but in the consumer abandonment scenario, the producer will detect that the channel has closed during its next put (then walks away, too.) I don't understand the distinction between send+timeout and sendSynchronously(). Isn't synchronicity more a property of whether a buffer is present or not (rendezvous channel)? Same question re: tryReceiveEventually I love that there is something CSP-like going into the JVM - it will be killer when Loom drops.

Would there be a use case where the sender side of a connection is the subject of a try-with-resources, where the end of the block needs to issue a `finishSending` call? In that case, the sender side (in isolation from the whole channel) might benefit from a view object whose close method is an alias for `finishSending`.

Same for offer, put and various send, including the versions with timeouts. The substantial difference is in dealing with "closed" states in blocking send/receive. It is difficult to signal that state without changing return type. Returning arbitrary references or null is a source of errors. I see returning Optional as a necessary deviation from the direct mapping of the blocking put/take, but I see dealing with Optional can also be awkward. I guess we'll wait and see. SendSynchronous is not just a wait for send to succeed, it also ensures the corresponding receive consuming the sent item has occurred. You can see this as an ack of that item and all the preceding items, although I don't know if the API goes as far as the guarantee for the preceding receives.

Yeah, I was going to ask something similar, about how we see common usage of senders. I suspect that a lot (the majority?) of folk will want orderly shutdown on the sender-side, so will invoke `shutdownSending`, which first disables further sending, and secondly closes when empty. For scenarios where the receiver and sender do not have intimate or direct knowledge of each other, then I'm not sure if it makes all that much sense to use a try-with-resources on the sender side - unless it is being used as an abort mechanism if orderly-close has not been completed by the end of the try-with-resources block. If we think that orderly-close will be more common that abortive-close, then it could be made the default, and an explicit method added to CarrierSender for abortive-close. This would more easily facilitate the use within try-with-resources blocks - but of course the resource is not really "freed", that depends on a well-behaved receiver. I don't think that this would have any adverse negative affect on the receiver. -Chris.

I have a few notes based on our experience with Kotlin Channel's API: 1) isFull method. We used to have it as well and eventually decided to deprecate it. We didn't find any compelling use-cases, its semantics is vague (e.g. is "TransferCarrier" always full?), and it is hard to make it linearizable with the rest of operations for buffered carriers. 2) receive throws ClosedException (that is IllegalStateException). To be somehow consistent with the Collections API, we've decided that attempt to receive from a closed carrier/channel is similar to 'remove' from an empty queue and thus should be NoSuchElementException. Send attempt to a closed channel, though, is still IllegalStateException. Maybe it is something worth considering here as well. 3) trySend. We have an analogue called offer, that also returns boolean, **but** may throw an exception if a channel was closed with an exception (aka "failure" rather than a normal close). In retrospect, this was not the best design decision: users do not expect method with a signature 'boolean offer(value)' to throw. We currently are thinking about migrating users to 'trySend' that never throws. The question here is whether to return boolean or some value-type like "Try" or "Either" to avoid check-and-act misusages. Otherwise, it is impossible to deterministically know whether 'trySend' failed because the source was closed or because buffer was full. 4) Conflation. There are primitives (in Channels, Rx, etc.) that allow value conflation: if there is no place in a (usually, single-slot) buffer on send, the current value just gets overwritten. I am not sure whether such API is in the scope of Carrier API, but if so, contracts around Carriable methods (capacity, estimatedSize, close etc.) require a really careful wording to make conflation fit here. 5) Send atomicity along with cancellation. If one sends a closeable resource via carrier, is there any guarantee on when it is safe to close a resource on the sending side (because a carrier is closed and there are no receivers) and when it is not? E.g. if 'send' throws ClosedException or CancellationException, is it safe to close an item in a catch block? "upon timeout, the item is no longer available" on send with timeout really caught my eye here.

In the mean-time, look for "since 99" in the javadoc for Thread, Thread.Builder, and ExecutorService (don't read anything into "@since 99", its just a placeholder). There are samples in the javadoc of several methods and hopefully will be enough to get you started. -Alan.

Just to set expectations, it's probably best for those trying out the EA builds to ignore the Continuation class. Yes, it is tempting to start there but this project isn't planing to directly expose continuations at this time (Continuation will probably move to a non-exported package as some point). Your second point is good, a lot of existing code that creates threads or uses executor service, can be changed to use virtual threads. We're interested to hear how far people can get. There are some limitations, like pinning when doing blocking I/O while holding a monitor, so we are interested to hear how much effort it was to migrate existing code. We are also interested in performance/benchmarks and stability/bug reports. -Alan From duke at openjdk.java.net Tue Mar 17 19:03:11 2020 From: duke at openjdk.java.net (duke) Date: Tue, 17 Mar 2020 19:03:11 GMT Subject: git: openjdk/loom: fibers: 2 new changesets Message-ID: <57119ccd-d1d9-42f7-939f-248032be7733@openjdk.java.net> Changeset: ad2b3ba6 Author: Ron Pressler Date: 2020-03-17 19:01:23 +0000 URL: https://git.openjdk.java.net/loom/commit/ad2b3ba6 Partially prepare continuation chunks for concurrent collectors !
