TypeError: range() integer step argument expected, got float.

Hi,

Recently i have upgrade the Robot framework to version 3.2.1 (python 2.7.17) and it seems that my old stable version of pabot == 0.96 version is not compatible anymore due to parser changes in robot framework. I have decide to upgrade Pabot to version 1.3.0.

I am not sure if this is an known issue but i am receiving the below unhandle exception:

rfdryrun run-test: commands[1] | pabot --extension robot --dryrun --exclude NoDryRun -d /home/vagrant/repo/logs/pabot_results testcases

TypeError: range() integer step argument expected, got float.

The same exception is being raised at version 1.8.0:

  File "/home/vagrant/repo/.tox/rfdryrun/lib/python2.7/site-packages/pabot/pabot.py", line 1219, in _chunk_items
    for i in range(0, len(items), chunk_size):
TypeError: range() integer step argument expected, got float.

This error seems to be appeared after Pabot version 1.2.0 in conjuction with robot-framework==3.2.1

Thanks, Theodore G.

Thank you for your time!

Looks like Python2 behavior here: https://github.com/mkorpela/pabot/blob/cba0338b5d2b5742e21e00e7e44990e753627a01/pabot/pabot.py#L1211 round returns float value

Replacing round with int will solve the issue.

Hi @mkorpela,

It seems that solving this issue will unblock the upgrade of pabot library up to version 1.8.0 and the usage of robotframework>=3.2.0 having python2.x. I had made some tests with pabot version>0.96 and <1.8.0 and something is wrong with the generation of .pabotsuitenames file (is taking too long to be generated, need further investigation) which seems to be fixed at v1.8.0.

To sum up, due this issue the latest stable python2.x release is pabot==0.96 (robotframework==3.1.1), is there any plan to be fixed in the next pabot releases?

Thank you in advance, Theodore G.
