Test task deadlocking with --parallel

cpietrafeso · August 19, 2016, 12:11am

Gradle Version: 3.0
Operating System: Linux (Fedora)
Is this a regression? If yes, which version of Gradle do you know it last worked for? Yes, worked in 2.13

There seems to be some kind of dead lock when using --parallel for me as the build just stops (for many versions of Gradle). I’ll post something about this separately (with more info and jstack dumps). However as a work-around I’ve been iterating over a list of Project(s) and and using GParsPool to execute the unit tests for each project usinga threadpool like so:

From a custom task like this:

 GParsPool.withPool(threads.toInteger()) {
    projectsToTest.eachParallel { proj ->
       proj.tasks.test.execute()  //this throws and IlleagalStateException
    }
}

For every project that I try this in for Gradle 3.0 I get the following exception:

This has been working fine in the 2.x line and was failing as soon as I went to 3.0.

The execute method of tasks is not meant to be called by clients. Gradle executes tasks for you. The test task has options for parallel test execution.

cpietrafeso · August 19, 2016, 3:25pm

After more investigation my projects are probably too coupled for the --parallel feature to be used since we have subprojects and allprojects configurations in the root project. The child projects don’t interact any more than this from what I can see, but --parallel still freezes (not fails, just pauses forever) about 50-60% though the full Java compile (it’s really fast up to that point). Executing just JUnit tests performs about the same. BTW: we are talking a very large code-base with 175+ sub-projects and several million lines of code.

st_oehme · August 19, 2016, 3:27pm

Configuration is always serial at the moment, so this has nothing to do with subprojects/allprojects. As mentioned above you are simply using the Test task API in a way that is not intended or supported.

cpietrafeso · August 19, 2016, 3:48pm

I was just going off what the Gradle docs say about coupling projects and that causing issues with --parallel. As far as “not supported” its not an internal API or anything. It is exposed, documented, and has worked since the early Gradle 1.x days.

st_oehme · August 19, 2016, 6:57pm

Because subclasses are free to override it to add additional behavior.

That doesn’t mean you can call it whenever you want Gradle’s task execution engine executes tasks for you, you should never call their execute() method yourself.

cpietrafeso · August 19, 2016, 7:08pm

OK, so how would I manually call a task to execute? I’ve read in other forum posts that this was the way to do it. Is there a way to access the task execution engine to do this. Basically call one task from another conditionally?

st_oehme · August 19, 2016, 7:13pm

There is not, tasks are selected based on what the users specifies on the command line. Could you please explain your use case, I’m sure we can find a solution.

Sorry, I just read the comment in the initial post that you had problems with --parallel. That should work much better in 3.0. If you still have problems, more detailed information like stack dumps would be awesome.

cpietrafeso · August 19, 2016, 8:23pm

Yea it’s still an issue with 3.0 for me. Below are some jstacks. I did however noticed when trying to get --debug output for this as well that it seems to get further along in the build.

I ran this: ./gradlew test --parallel --no-daemon

Here is a jstack of the command: java -XX:MaxPermSize=768m -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/tmp -Xmx3072m -Dfile.encoding=UTF-8 -Duser.country=US -Duser.language=en -Duser.variant -cp /home/cpietrafeso/.gradle/wrapper/dists/gradle-3.0-all/3kcb6ymmejv7hloxlb6ofnzbe/gradle-3.0/lib/gradle-launcher-3.0.jar org.gradle.launcher.daemon.bootstrap.GradleDaemon 3.0

Thanks for the stacktraces! We will have a deeper look at them.

You could speed up the process even more by creating a reproducible example. Maybe you could strip down your project so it is safe to share, but still shows the problem? Like deleting all production code, changing the tests to just do some dummy operations like Thread.sleep and obfuscating the project names.

cpietrafeso · August 22, 2016, 3:44pm

I haven’t been successful at creating an example yet. The failure (lock) is only on a large code base (179 projects) with lots of dependencies. It seems to happen regardless running a compileJava or test task (any task really). My more simplified tests haven’t hit it yet so I’m just not reproducing what the real stuff is doing yet. I’ll keep trying though.
