Software Tests: "Address already in use" #3

Closed cmarxer closed 6 years ago

cmarxer commented 6 years ago

Occasionally, a software test fails due to OS Error "Address already in use":

======================================================================
1) ERROR: Test adding content
----------------------------------------------------------------------
   Traceback (most recent call last):
    /home/claudio/software/PiCN/PiCN/Mgmt/test/test_Mgmt.py line 24 in setUp
      self.linklayer = UDP4LinkLayer(9000+self.portoffset)
    /home/claudio/software/PiCN/PiCN/Layers/LinkLayer/UDP4LinkLayer.py line 25 in __init__
      self.sock.bind(("0.0.0.0", self._port))
   OSError: [Errno 98] Address already in use

Running to many tests. Port selection is already randomized, which doesn't seem to be sufficient. must be changed in some way. OS keeps ports to long open.

blacksheeep commented 6 years ago

I think the solution here is to let the OS choose the port, I start changing the tests to do so.

blacksheeep commented 6 years ago

seems to fix that bug.

Now occurs less often, but still:

======================================================================
ERROR: test_fetch_small_data (PiCN.ProgramLibs.ICNDataRepository.test.test_ICNDataRepository.test_ICNDataRepository)

Still got this on this point:

ERROR: test_fetching_content_from_second_repo_after_nack (PiCN.ProgramLibs.Fetch.test.test_Fetch.test_Fetch) Test sending an interest to forwarder with no matching content, choose second route to fetch content

Doesn't occur any more.
