[Mobilitydb-dev] Fwd: Regression tests for MobilityDB: Continous shutdowns at a random step

[Regina Obe]

I think he is assuming your tests are launching and exiting the session instead of your session launch and end being separate from the tests.

 

I haven’t gotten to the point of being able to run the tests so hard for me to debug.

 

So do you get this when testing locally or it is in your CI?  I think some Cis if the tests take too long, it shuts them down and that triggers a sigint to the Postgres postmaster process.  That would cause breaks in random places. That’s happened to me in past with travis and sometimes cloud drone  or github actions.  Though with those you usually see a clearer message like “Time exceeded”.

Thanks Regina for the answer. 

 

The weird thing is that this happens randomly, sometimes the tests go smoothly, and sometimes I need to restart them many times. This is problematic when I am changing the tests, as I am currently doing now, so that the results of the tests are independent of whether we use PostGIS 2.5.5. or 3. In this case, I change one particular file of tests, I need to obtain the new result file, verify that it is correct, and "publish" it in the corresponding "expected" directory.

 

And what does "decouple the test processes from your terminal session" mean ?

He’s saying he thinks you have something explicitly in your tests requesting a postgresql terminate process.

I haven’t checked your tests to see what that might be.

 

I normally have one script to start up the Postgres process, regress, and then another script to wait a few seconds and shutdown if that helps at all.

Can anyone help me to decrypt what Tom answered me ?

This indicates that something sent the postmaster SIGINT.
You need to look around for something in your test environment
that would do that.  Possibly you need to decouple the test
processes from your terminal session?
