QNetworkAccessManager doesn't recover when network is reconnected

XMLWordPrintable

    • c89d0f9d532a2719118614b9fa9b8efffbe12f2f (qt/qtbase/5.12.1) ced53c483da3b1d55850d2087d9a743983c8b944 (qt/qtbase/5.9)

      Steps to reproduce:

      • Run attached test case.
      • Disable the network using the network manager tray icon.
      • The in progress request fails with 'NetworkSessionFailedError'.
      • Subsequent requests fail with 'UnknownNetworkError'.
      • Reenable the network using the network manager tray icon.
      • Requests continue to fail indefinitely with 'UnknownNetworkError'.

      Expected behaviour:

      • Once the network is reenabled, subsequent requests should complete successfully.

      This bug does not happen (i.e. requests complete successfully once network is reconnected):

      • If libqnmbearer.so is disabled (by chmod'ing to 0).
      • On Windows (network enabled/disabled using 'Network Connections').
