14:14 <aakashjain> p12tic: tardyp: any idea about this error: https://ews-build.webkit.org/#/builders/34/builds/31061/steps/0/logs/err_text

14:14 <aakashjain> File "/usr/local/lib/python3.6/site-packages/buildbot/process/build.py", line 507, in setupBuild

14:14 <aakashjain> builtins.TypeError: '<' not supported between instances of 'NoneType' and 'str'

14:14 <aakashjain> self.setProperty('owners', sorted(owners), 'Build')

14:14 <aakashjain> seems like this issue happens when owners property is not set (while sending through buildbot try)

14:19 <aakashjain> i filed: https://github.com/buildbot/buildbot/issues/5852

14:20 <tardyp> one of your owners must be None

14:20 <tardyp> the sorted tries to apply < with something being None inside

14:20 <tardyp> aakashjain: ^^

14:22 <aakashjain> tardyp: yeah, i sent this patch using buildbot try and didn't set owners property. I used this command:

14:22 <aakashjain> buildbot try --connect=pb --master=server-name:5555 --username=buildbot_try --passwd=*** --diff=1111.patch --repository='' --property='patch_id=1111'

14:23 <aakashjain> it's weird that some of the queues processed this patch properly, while some queues hit this exception

14:23 <tardyp> I agree that we shouldn\t propagate None in owners

14:24 <aakashjain> e.g.: https://ews-build.webkit.org/#/builders/6/builds/41909 passed while https://ews-build.webkit.org/#/builders/34/builds/31061 failed. Both builds were triggered using same/single 'buildbot try' command

14:26 <aakashjain> actually i notice a pattern, all the (tester) builds which were triggerred by another (builder) build hit this exception.

14:26 <aakashjain> e.g.: https://ews-build.webkit.org/#/builders/51/builds/8424, https://ews-build.webkit.org/#/builders/57/builds/3000, https://ews-build.webkit.org/#/builders/56/builds/2878

14:26 <aakashjain> tardyp: Maybe some issue with trigger step not handling empty owners property.

14:51 <Zorry> is there a way to get master in change_source as you can do in schedulers?

16:39 <tardyp> p12tic: yeah! works with chrome!
