Bug Summary

I'm trying to retrieve a lot of channel information near a seismic event, from the client NCEDC. the request times out, but the handle of the server response is not properly done by obspy it seems.

Code to Reproduce

def load_or_create_inventory(
    client, client_name, event, path_observations, spatial_range, t_before, t_after
):
    fn_inventory = f"{path_observations}/inv_{client_name}.xml"
    if os.path.exists(fn_inventory):
        inventory = read_inventory(fn_inventory)
    else:
        starttime = event["onset"] - t_before
        endtime = event["onset"] + t_after
        kargs = {}
        r0, r1 = spatial_range["radius"]
        if "source_lon_range" in spatial_range.keys():
            kargs["minlongitude"] = spatial_range["source_lon_range"][0] - r1
            kargs["maxlongitude"] = spatial_range["source_lon_range"][1] + r1
            kargs["minlatitude"] = spatial_range["source_lat_range"][0] - r1
            kargs["maxlatitude"] = spatial_range["source_lat_range"][1] + r1
        else:
            kargs["minradius"] = r0
            kargs["maxradius"] = r1
            kargs["latitude"] = event["latitude"]
            kargs["longitude"] = event["longitude"]
            if r1 > 30:
                kargs["network"] = "IU,II,GE,G"
                print(f"Warning: restricting to networks {kargs['network']} for teleseismic")

        print(kargs)
        try:
            inventory = client.get_stations(
                starttime=starttime,
                endtime=endtime,
                level="channel",
                channel="*",
                includerestricted=False,
                includeavailability=True,
                **kargs,
            )
        except TypeError:
            # TypeError: The parameter 'includerestricted' is not supported by the service.
            inventory = client.get_stations(
                starttime=starttime,
                endtime=endtime,
                level="channel",
                channel="*",
                includeavailability=True,
                **kargs,
            )
        inventory = filter_channels_by_availability(inventory, starttime, endtime)
        inventory.write(fn_inventory, format="STATIONXML")
    return inventory

        if server_info:
            server_info = "\n".join(
                line for line in str(server_info).splitlines() if line)

fixes the problem it seems

My guess is this is a duplicate of #3320 and fixed on master branch by #3306

This solution doesn't work as TimeoutError gets interpreted as True.

In [1]: bool(TimeoutError)
Out[1]: True

We might be able to use server_info == TimeoutError, but that seems clunky. I looked through the code base trying to understand why server_info gets set to TimeoutError, but I don't see it.

Hi,

Just to confirm that the error is still there with obspy 1.4.2 (I was using iris client):
