      dir: Do not flag non-running failing HSDir · cac612af
      David Goulet authored
      
      
      When a directory request fails, we flag the relay as non Running so we
      don't use it anymore.
      
      This can be problematic with onion services because there are cases
      where a tor instance could have a lot of services, ephemeral ones, and
      keeps failing to upload descriptors, let say due to a bad network, and
      thus flag a lot of nodes as non Running which then in turn can not be
      used for circuit building.
      
      This commit makes it that we never flag nodes as non Running on a onion
      service directory request (upload or fetch) failure as to keep the
      hashring intact and not affect other parts of tor.
      
      Fortunately, the onion service hashring is _not_ selected by looking at
      the Running flag but since we do a 3-hop circuit to the HSDir, other
      services on the same instance can influence each other by removing nodes
      from the consensus for path selection.
      
      This was made apparent with a small network that ran out of nodes to
      used due to rapid succession of onion services uploading and failing.
      See #40434 for details.
      
      Fixes #40434
