[HTCondor-users] python-bindings and flask

[Ricardo Oda <odaric@xxxxxxxxxx>]

Hello,

I was developing a simple monitoring tool for my experiments and then I got into a weird bug. I am using htcondor python-bindings to query stuff and Flask(http://flask.pocoo.org/) as my front-end to show it.

The following code in python works fine:

> import htcondor
> collector = htcondor.Collector(COLLECTOR_HOST)

> schedd_ad = collector.locate(htcondor.DaemonTypes.Schedd, SCHEDD_HOST)

> schedd = htcondor.Schedd(schedd_ad)

> schedd.query()

But ifÂÂtheres a job running in my condor pool andÂI add the following line at the beginning of the code:

> from flask import Flask

The schedd.query() does not return, it stops responding.

It took me some time to find out that the flask import was the cause for my web server to stop responding. I am not sure if my enviroment is contributing to this conflict or not.

I know it's a python related issue, but I would be grateful if someone can help me with this one.

Thanks,

Ricardo Oda
