MAPDL nightly check is broken since #991

[germa89]

MAPDL nightly check is broken since #991 was approved and merged.

The reason seems to be in the test_database_start_stop function.

def test_database_start_stop(mapdl):
    if mapdl._server_version < (0, 4, 1):  # 2021R2
        pytest.skip("requires 2021R2 or newer")

    # verify it can be created twice
    mapdl.prep7()
    for _ in range(2):
        database = MapdlDb(mapdl)
        assert not database.active  # This fails
        database.start()
        assert database.active

I'm looking into this.

I am not sure anymore the reason is in that specific test.

However, it is clear the reason is the newly added database functions.

Running these tests in my local machine I keep getting this error:

Inspecting that file fort.39, I see:

 Start GRPC DBServer

It seems the output is diverted to this file, and they we tried to overwrite it. To me it seems these DB functions needs to be grpc protected, I'm testing that.

@FredAns, is mapdl database broken in the latest version?

[FredAns]

What MAPDL Release is used ? ( Assuming it's windows here)

[germa89]

Windows 11, Ansys v21.2

Windows 11, Ansys v21.2

Thanks German. This build did not changed since months now. Is it reproductible ?

[akaszynski]

It's broken on the latest MAPDL, so I'm guessing it's on both Linux and Windows on the latest.

[germa89]

mmhhh....

But... my machine uses v212 (grpc 0.4.1) and Windows.

The PyMAPDL repo uses v21.1 and v21.2 with Linux, and the tests passes.

The nightly MAPDL check uses the private v22.1RC0 on Linux, and it is broken.

I can't see the pattern here.

Nightly uses ghcr.io/pyansys/mapdl:latest, which is:

 | Ansys 2022 R2               Build 22.2BETA     UP20220306     LINUX x64   |

Conclusion: Latest is broken. Somewhere between 2021R2 and 2022R2 the DB service broke.

Hi Alex,
Yes, the DB Server in 22.2 on Linux is broken when used through a grpc MAPDL Server.
I'm working on it.

It works fine on Windows I think, only Linux is concerned

Any updates on this?
