Description
While investigating JDK-8345147 I ran jdk.jfr.api.consumer.streaming.TestJVMCrash locally (macOS 14.7) and got timeout errors.

ACTION: main -- Error. Program `/Users/gerard/Work/bugs/8345147/jdk/./build/xcode/build/jdk/bin/java' timed out (timeout set to 120000ms, elapsed time including timeout handling was 120276ms).
REASON: User specified action: run main/othervm -Dsun.tools.attach.attachTimeout=100000 jdk.jfr.api.consumer.streaming.TestJVMCrash
TIME: 120.288 seconds
messages:

I think this should be closed as a duplicate of JDK-8344671. Thanks

Waiting to see if it's still happening. I was at one point able to easily reproduce it, but after a restart of my machine I can no longer reproduce it.
03-03-2025
I can no longer reproduce it after I restarted my mac. Probably some macOS quirk. I will keep it open for a while to see if it comes back. The last I was debugging I was suspecting some timing issue, between creating/starting TestProcess main() and creating the pipeline file through which it was communicating.

So far I can see the attach always fails, this is how we launch the server process: # ./build/macosx-aarch64-server-release/xcode/build/jdk/bin/java --add-exports=java.base/jdk.internal.misc=ALL-UNNAMED -XX:StartFlightRecording:settings=none -XX:+CreateCoredumpOnCrash 'jdk.jfr.api.consumer.streaming.TestProcess' /Users/gerard/Work/bugs/8345500/jdk/JTwork/scratch/action-1737670642918 OpenJDK 64-Bit Server VM warning: CreateCoredumpOnCrash specified, but Core dumps have been disabled.

Yep, I saw tons of "Attach failed". It seems on macOS things happen so quickly, that the other threads did not see the process after it was created. From the thread the process was created all was peachy, but the other threads thought the process died, when in fact it wasn't visible to those threads yet, so we thought the process exited and went through the loop again, creating a new process, failing to see it and so on.
16-01-2025
Hopefully that takes care of JDK-8344671 as well.

You see "Attach failed" in the output, right? The test spins, waiting for the server process to become attachable.

[~egahlin] Thank you!

[~gziemski] Purpose of the test (the client) is to see that an event stream against another process (the server) can handle a JVM crash. The client uses the attach mechanism to get a system property ("jdk.jfr.repository") which contains the path where the server writes event data to. Once it has the file path it can then read events from server's disk repository. Problem here seems to be that it can't attach, because there is no such process. This can happen if the server application crashes or exits at startup, for whatever reason. If this happens, the client launches a new server process and tries again. If it is never able to attach, the test times out. This is essentially the program: while (true) { String[] args = { "--add-exports", "java.base/jdk.internal.misc=ALL-UNNAMED", "-XX:StartFlightRecording:settings=none", "-XX:" + (createCore ? "+" : "-") + "CreateCoredumpOnCrash", "TestProcess.class.getName(), path.toString() }; ProcessBuilder pb = ProcessTools.createLimitedTestJavaProcessBuilder(args); process = ProcessTools.startProcess(name, pb); try { VirtualMachine vm = VirtualMachine.attach(String.valueOf(process.pid())); // String repository = vm.getSystemProperties().getProperty("jdk.jfr.repository"); vm.detach(); ... test streaming } catch (Exception e) { System.out.println("Attach failed: " + e.getMessage()); System.out.println("Retrying..."); } } The server process polls a file and if it contains the word "crash" it does an Unsafe.getUnsafe().putInt(0L, 0), but it looks like the server never gets this far.

[~egahlin] Erik, would you kindly explain in more detail what this test is trying to do and how? I just don't understand of what is happening here.
23-12-2024
I was able to reproduce after syncing with main. Looks like the test is not able to attach Attach failed: No such process Retrying... Attach failed: No such process Retrying... Attach failed: No such process Retrying... When we shorten the interval, it is more likely to succeed as the number of attempts increases.
09-12-2024
Using the above fix helps. I only got 6 timeouts running "test/jdk/jdk/jfr/api/consumer/streaming" tests 10 times, but they still occur. Without this fix, however, I'd probably see more like 50 timeouts.
06-12-2024
I have not been able to reproduce on my Mac (M4). One idea is to remove the attach timeout, so the test gets to try more than one or two crashes. diff --git a/test/jdk/jdk/jfr/api/consumer/streaming/TestJVMCrash.java b/test/jdk/jdk/jfr/api/consumer/streaming/TestJVMCrash.java index e1a95380477..8d948f783d0 100644 --- a/test/jdk/jdk/jfr/api/consumer/streaming/TestJVMCrash.java +++ b/test/jdk/jdk/jfr/api/consumer/streaming/TestJVMCrash.java @@ -36,7 +36,7 @@ * @library /test/lib /test/jdk * @modules jdk.jfr jdk.attach java.base/jdk.internal.misc * - * @run main/othervm -Dsun.tools.attach.attachTimeout=100000 jdk.jfr.api.consumer.streaming.TestJVMCrash + * @run main/othervm jdk.jfr.api.consumer.streaming.TestJVMCrash */ public class TestJVMCrash {

From the thread dump, it looks like the timeout happens because the test is stuck in the loop trying to attach.

05-12-2024
The timeouts are easily reproducible (near always) on macOS 14.x or 15.x
04-12-2024
According to https://developer.apple.com/documentation/xcode/sigquit this simply means that a timed-out process got killed, so this would represent an expected behavior. The timeout itself, however, is unexpected.
