LDTP v1.7.1 http_proxy/HTTP_PROXY changes impact on client-server cnx

[Nouar Garcia-Mardambek]

Hi ldtp-experts,

I've an application (python / wxpython) that reads a configuration file when it launched and set/unset the python environment variables:
HTTP_PROXY/http_proxy to the URL of the http proxy to be used if any is defined, or keep a direct connection to the internet.

This application provides a Preferences menu to set the information about the http (and https) proxy settings + 2 radio buttons to toggle between the two network configurations. The dialog is very similar to the Connection Settings in Firefox.

The same function is called when the application is started and when it changes the proxy setting in the Preferences menu:
proxy holds the definition of the http proxy URL built up.
os.environ['HTTP_PROXY'] = os.environ['http_proxy'] =  proxy
os.environ['FTP_PROXY'] = os.environ['ftp_proxy'] =  proxy
urllib2.install_opener(urllib2.build_opener(urllib2.ProxyHandler()))

I've written a script A:
1) launch my application with launchapp()
2) change the Connection Settings by calling this menu Preferences
3) go back to the main frame
4) call another dialog that does not deal with the network
5) select a view that uses the proxy set to fetch over the network the needed data
6) check if any Error window is showing up, if none call a Quit menu and exit the application

On OpenSolaris 2009.06 and ubuntu 9.04 with ldtp 1.7.1,  I've noticed if I launch this test in a python script, all the steps are executed as expected without any problem. I can run the script in a loop without problem.

When this test is launched by pyunit (TestSuite/TestCase/TextTestRunner), any additional tests executed after, over the same application fail in the call of  guiexist/waittillguiexist(main_frame): the call pauses for a while and after gets the error: TypeError unpack non-sequence as a response although the application is launched with success.

In my execution environment LDTP_DEBUG is set to 2, am I breaking the connection between the server and the client during this test and only sys.exit() clean up the situation by closing the sockets ? does reinitldtp( ) fix my issue as I don't understand what's really doing ?

Looking forward to your advice, best regards.

nouar.

Hi Nouar,

This is interesting to know :) In our automation environment in VMware, we do have http_proxy settings, we haven't noticed any such issue. If this is an Open Source project, can I verify it ?

Thanks
