I am trying to write tests with selenium and I am using ChannelsLiveServerTestCase.
I need to set the port the server listens to.
I suppose this should be a rare situation where someone needs to set the port as no one answered the question.
Anyway, I had to dig into the source code of daphne.
In testing.py file look for the line
endpoints = build_endpoint_description_strings(host=self.host, port=0)
in my case it was line 139 and change it into
endpoints = build_endpoint_description_strings(host=self.host, port=WHICHEVER_PORT_YOU_WANT)

Our project has a few GRPC servers defined as go_binary targets. We develop client SDKs for Java and Python applications and we would like to use java_test and py_test. Is any way to start a specific go_binary target before java_test or py_test?
You can create a test harness that starts the gRPC server before running the tests. For example, you could add the binary to the data attribute of the test, and then started it beforehand:
go_binary(
name = "my_grpc_server",
[...]
)
py_test(
name = "my_test",
[...]
data = [":my_grpc_server"],
)
and then inside the test file:
class ClientTestCase(unittest.TestCase):
def setUp(self):
r = runfiles.Create()
self.server = subprocess.Popen([r.Rlocation("path/to/my_grpc_server")])
def tearDown(self):
self.server.terminate()
self.server.wait()
This example is very simple, you'll probably run into issues regarding the availability of the port the server listens on, or waiting for the server to start up. You could add flags to your gRPC server to allow communication over a domain socket, or make it listen on an unused port and have the test parse the port number from the server's log output.
For details on finding the server with runfiles: https://github.com/bazelbuild/bazel/blob/a7a0d48fbeb059ee60e77580e5d05baeefdd5699/tools/python/runfiles/runfiles.py#L16-L58
If you find yourself copy-pasting this pattern a lot, or having to implement it in multiple languages, you could try using an sh_test() rule to wrap the underlying py_test or java_test, and to start the server, then start the test with an environment variable telling it how to reach the server (eg MY_GRPC_SERVER_ADDRESS=localhost:${test_port}.
So I have two freeradius / radiusdesk installations on the server.
First one is old one and uses default freeradius ports: 1812/1813 for Auth/Acct.
The second one is the new once and using ports: 10001/10002 for Auth/Acct.
The issue now is that on my router, CoovaChili is always connection to the first one ( old one ) and communicating on the ports 1812/1813. I want to change it's ports. But it doesn't seems to be working. The OS is OpenWrt.
In my /etc/config/chilli i have added the following lines:
option radiusauthport 10001
option radiusacctport 10002
But is is not working. CoovaChilli still sends request to the old 1812/1813 ports. I want to know how to change that so it communicates with my defined port numbers, rather than the default ones.
Looking for the configurations to fix it.
Thanks
Looking at the OpernWRT guide at https://openwrt.org/docs/guide-user/services/captive-portal/wireless.hotspot.coova-chilli, it seems that you need to put the value parameter inside double quotes.
Specifically
option radiusauthport "10001"
option radiusacctport "10002
I am working on IB Gateway and want to get the historical data.
As i have completed the steps on IB Gateway software to enable the API.
I am using python notebook for this.
For now i am running this code and i am able to import the given library but rest of the code giving me this error. Important thing is connection is established as I have mention client id 1. then it is created and can be seen on IB Gateway application.
My code is here.
from ib_insync import *
#util.startLoop() # uncomment this line when in a notebook
ib = IB()
ib.connect('127.0.0.1', 5021, clientId=1)
bars = ib.reqHistoricalData(
contract=Stock('TSLA', 'SMART', 'USD'),
endDateTime='',
durationStr='30 D',
barSizeSetting='1 hour',
whatToShow='TRADES',
useRTH=True)
print(bars)
Here is the error.
Peer closed connection
clientId 1 already in use?
API connection failed: CancelledError()
As i am using notebook if i uncomment the second line (util.startLoop()) it adds one more error about timeout..
Need help to get this done.
Big Thanks
Assign a different clientID to this connecion:
ib.connect('127.0.0.1', 5021, clientId=2)
Apparently you already have another connection with clientId=1.
Say I want to use FTP in Python using the ftplib. I begin with this:
from ftplib import ftp
ftp = FTP('10.10.10.151')
If the FTP server is not online, however, it will hang right there indefinitely. The only thing that can kick it out is a keyboard interrupt as far as I know. I've tried this:
ftp.connect('10.10.10.151','21', 5)
With the five being a five second timeout. But the problem here is that I do not know of any way to use that line without first assigning ftp something. But if the server is offline, then the "ftp =" line will hang. So what use is ftp.connect()'s timeout function?!?
Does anybody know a workaround or anything? Is there a way to time out the "ftp = FTP(xxx)" command that I haven't found? Thanks.
I'm using Python 2.7 on Linux Mint.
Your call to connect() is redundant since FTP() method documentation states:
When host is given, the method call connect(host) is made.
Also, since Python 2.6, FTP() does have a timeout parameter:
class ftplib.FTP([host[, user[, passwd[, acct[, timeout]]]]])
The optional timeout parameter specifies a timeout in seconds for blocking operations like the connection attempt (if is not specified, the global default timeout setting will be used).
I have a problem with changing the standard options used by an Axis 1.4 generated web service client code.
We consume a certain web service of a partner who is using the old RPC/Encoded style, which basically means we're not able to go for Axis 2 but are limited to Axis 1.4.
The service client is retrieving data from the remote server through our proxy which actually runs quite nicely.
Our application is deployed as a servlet. The retrieved response of the foreign web service is inserted into a (XML) document we provide to our internal systems/CMS.
But if the external service is not responding - which didn't happen yet but might happen at anytime - we want to degrade nicely and return our produced XML document without the calculated web service information within a resonable time.
The data retrieved is optional (if this specific calculation is missing it isn't a big issue at all).
So I tried to change the timeout settings. I did apply/use all methods and keys I could find in the documentation of axis to alter the connection and socket timeouts by searching the web.
None of these seems to influence the connection timeouts.
Can anyone give me advice how to alter the settings for an axis stub/service/port based on version 1.4?
Here's an example for the several configurations I tried:
MyService service = new MyServiceLocator();
MyServicePort port = null;
try {
port = service.getMyServicePort();
javax.xml.rpc.Stub stub = (javax.xml.rpc.Stub) port;
stub._setProperty("axis.connection.timeout", 10);
stub._setProperty(org.apache.axis.client.Call.CONNECTION_TIMEOUT_PROPERTY, 10);
stub._setProperty(org.apache.axis.components.net.DefaultCommonsHTTPClientProperties.CONNECTION_DEFAULT_CONNECTION_TIMEOUT_KEY, 10);
stub._setProperty(org.apache.axis.components.net.DefaultCommonsHTTPClientProperties.CONNECTION_DEFAULT_SO_TIMEOUT_KEY, 10);
AxisProperties.setProperty("axis.connection.timeout", "10");
AxisProperties.setProperty(org.apache.axis.client.Call.CONNECTION_TIMEOUT_PROPERTY, "10");
AxisProperties.setProperty(org.apache.axis.components.net.DefaultCommonsHTTPClientProperties.CONNECTION_DEFAULT_CONNECTION_TIMEOUT_KEY, "10");
AxisProperties.setProperty(org.apache.axis.components.net.DefaultCommonsHTTPClientProperties.CONNECTION_DEFAULT_SO_TIMEOUT_KEY, "10");
logger.error(AxisProperties.getProperties());
service = new MyClimateServiceLocator();
port = service.getMyServicePort();
}
I assigned the property changes before the generation of the service and after, I set the properties during initialisation, I tried several other timeout keys I found, ...
I think I'm getting mad about that and start to forget what I tried already!
What am I doing wrong? I mean there must be an option, mustn't it?
If I don't find a proper solution I thought about setting up a synchronized thread with a timeout within our code which actually feels quite awkward and somehow silly.
Can you imagine anything else?
Thanks in advance

I think it may be a bug, as indicated here:
https://issues.apache.org/jira/browse/AXIS-2493?jql=text%20~%20%22CONNECTION_DEFAULT_CONNECTION_TIMEOUT_KEY%22
Typecast service port object to org.apache.axis.client.Stub.
(i.e)
org.apache.axis.client.Stub stub = (org.apache.axis.client.Stub) port;
Then set all the properties:
stub._setProperty(org.apache.axis.client.Call.CONNECTION_TIMEOUT_PROPERTY, 10);
stub._setProperty(org.apache.axis.components.net.DefaultCommonsHTTPClientProperties.CONNECTION_DEFAULT_CONNECTION_TIMEOUT_KEY, 10);
stub._setProperty(org.apache.axis.components.net.DefaultCommonsHTTPClientProperties.CONNECTION_DEFAULT_SO_TIMEOUT_KEY, 10);
