Open Microscopy Environment

Hey Guys,

I'm trying to get the function conn.changeActiveGroup to work and I keep coming up with the following error. It works sometimes in one group that the user has created but not the others, despite the settings for the groups and the users being the exact same. I found the bug report on http://trac.openmicroscopy.org/ome/ticket/2339 that corresponds to it but I don't understand how I can work around it. Do I need to shut down the current session, and how do i do that (function/library)? I get it also when I try to change the session using the omero CLI using the same session as given in conn._getSessionId()


My code looks like (in webtest/views.py)
conn = kwargs['conn']
theAdminofGroup=conn._getSessionId()
ExImvar=conn.changeActiveGroup(154)
#ExImvar=dbconnect.mvImgtoDsPublicUsingexim(imgid,theAdminofGroup)
return HttpResponse(ExImvar)


The error is :-

Code: Select all

Hi,

what's happening is that stateful services which could still be in use are still active and therefore the group can't be changed. You will need to get a list of such services and then close them but only if you know that they are finished executing:

Code: Select all

services = g.c.getStatefulServices()
for service in services:
    service.close()


A full example is below.
Cheers,
~Josh

Code: Select all

import omero
import omero.gateway as og

g = og.BlitzGateway(username="root", group="system") # Your login here
g.connect()

g.c.sf.createRenderingEngine()
services = g.c.getStatefulServices()

def test():
    old = g.c.sf.setSecurityContext(omero.model.ExperimenterGroupI(1, False))
    print "Set group to 1. Old group was: %s" % old.id.val

try:
    test()
    print "will never reach here"
except:
    print "Stateful services:", len(services)
    for service in services:
        try:
            service.close()
        except:
            print "Failed to close %s" % service
    test()


Thanks! That has closed the sessions, but now I cannot import an image. I'm using the following, the image is an image that I have imported before without issues and can again if I delete the lines you gave me.
