.Net (DotNet) tests get stuck with no reported errors or warning and I could not find the cause on Gitlab Runner's Kubernetes executor #27106

rshad · 2022-08-11T16:19:15Z

Describe the bug

We have a .Net repository whose pipelines run 3 stages build, test, and deployment.

1 one of the test jobs always gets stuck at a random point without reporting any error or warning that justifies this behavior. Note that this is running on Gitlab Runner's Kubernetes executor, and this same job, does not fail when using Gitlab Runner's Docker executor.

We're using .Net 6, and the latest Docker image of .Net SDK mcr.microsoft.com/dotnet/sdk:6.0

A sample output of the logs where the job gets stuck usually is

Test run for /builds/vistaprint-org/channel-technology/real-time-offer-service/api/src/MerchandisingFeeds.AcceptanceTests/bin/Release/net6.0/MerchandisingFeeds.AcceptanceTests.dll (.NETCoreApp,Version=v6.0)
Microsoft (R) Test Execution Command Line Tool Version 17.3.0 (x64)
Copyright (c) Microsoft Corporation.  All rights reserved.
Starting test execution, please wait...
A total of 1 test files matched the specified pattern.

I also enabled the detailed verbosity of the logs and no error or warning are reported.

I tried many workarounds and verifications which some are proposed in similar or alike reported issues and these workarounds are:

Run test jobs sequentially.
Change Dockerfiles' ENTRYPOINT from dotnet to bash.
Run the job on different instances with different computing capacities.
Verified that we have enough resources and disk space.

I also reviewed the logs of the Kubernetes pod and the corresponding container where the jobs' service is running and no errors/warnings or anything related are reported.

Some say that with .Net 5 this would be solved but in my case, it'd be really difficult to run the project with .Net 5 as this implies a lot of code changes.

similar failure cases are already reported and no clear solution or cause is reported. Related issues:

if you add parameter --diag:/some/folder/log.txt it will log diagnostics log of your run, and there we can see way more information. Would you be able to provide those logs please?

There is also --blame-hang-timeout 15min that would trigger hang dump after a test takes more than 15minutes. I see you describe this as being stuck after test run is done, so it might not apply. But might not hurt to try it.

Hi @nohwnd!

I retried the job with the parameters you mentioned above and below you can find the info you requested:

Regarding the parameter --blame-hang-timeout 15minI noticed that it did not have any effect. The test continued stuck for more than 15 minutes and no blame output was generated.

Kuinox · 2022-11-07T10:19:55Z

Hi, I think this issue is due to a bug in the Process type, I opened an issue about it here: dotnet/runtime#51277

In summary:

The issue is that WaitForExit() will synchronously wait for the stderr/stdout to complete, the summoned process has exited, but it has childs process still running (the nodereuse processes in msbuild case).
In this case, it looks like that the stderr/stdout pipes wont close.

Here I guess --blame-hang-timeout 15min doesn't do anything because it will try to kill a process that is already dead, and something is still stuck on WaitForExit()

olfek · 2023-01-16T13:20:41Z

I'm experiencing the exact same problem right now ☹️

  script:
    - 'dotnet restore'
    - 'dotnet build --no-restore <TESTS PROJECT>'
    - 'dotnet test --no-build --verbosity normal <TESTS PROJECT>'

Pretty straight forward I think

Okay this "solution" works for me ➡️ #9452 (comment)

codenesium · 2023-05-24T21:17:41Z

What we found was our TestWebapplicationFactory was calling async code in the Dispose Method(also occurs in the constructor) on that factory using .Wait(). In our case we were using xUnit version 2 which has a synchronization context and was being deadlocked. We were only able to see this info by running dotnet test with --blame-hang-dump-type full.

augustfengd · 2023-08-03T19:26:48Z

Our tests got a little bit further than OPs but still hang'ed.

I found a blog post and tried the xunit.runner.json workaround which worked marvellously.

Evengard · 2023-09-06T20:44:23Z

Beware of the ultimate workaround which seems (at least in my case with Jenkins pipelines running inside Kubernetes) to have COMPLETELY alleviated the issue!
No xunit.runner.json fiddling needed. No attributes needed. No parallelization disabling needed. No running with tini or smth like that. No weird properties passed on dotnet command or smth like that. No build server shutdown needed. No need to enable tty for the container.

Nothing of that.

The ultimate workaround is this:

sh -c "dotnet test yourproject.csproj & wait"

Yep, that's it. You can even omit the sh -c part with the double quotes if you run within a sh-compatible shell.

Honestly, I still don't completely understand WHY this workaround works (at least for me), it failed not once with it. Not once after that I had to wait those damn 15 minutes. It Just Works.

I have a teory that it somehow "unblocks" the dotnet test input/output fds which seems to somehow help to alleviate this issue, but I do not have any deeper understanding. I'm just happy, because I was fighting that bug for almost a year now.

Kuinox · 2023-09-06T21:03:19Z

I do keep thinking it's the Process.Start issue I keep referencing everywhere.
Since I suspect it's a Process.WaitForExit not returning because the output/error pipes don't close despite the process being exited, I can see your workaround messing with how pipes behave and avoid the issue in the end.

Hello Guys, I tried all options mentioned here, but nothing seems to work.

I solved my problem by turning off parallel test execution.
(It works on all configs I think I have tried it on
Jenkins pipelines running inside Kubernetes
&
Bamboo pipelines running inside docker)

In my test project >
Add folder Properties >
Add _AssemblyInfo.cs_
Add below code in the file

using Xunit;

[assembly: CollectionBehavior(DisableTestParallelization = true)]

We have hit a similar problem during the migration from .NET6 to .NET8. In our case the issue turned out to be an excessive memory usage caused by a task spawned in one of the tests. The task was effectively spinning in a short loop generating temp objects. This somehow worked in .NET6, but in .NET8 GC wasn't able to keep up with the task and it was periodically crashing the build agent. Enabling pipeline diagnostics and running locally with memory profiler allowed to spot the problem.
