[Gluster-devel] [Gluster-infra] New workflow proposal for glusterfs repo

Tue Jun 25 05:49:54 UTC 2019

Adding gluster-devel ML.

Only concern to my earlier proposal was not making regression runs wait for
reviews, but to be triggered automatically after successful smoke.

The ask was to put burden on machines than on developers, which I agree to
start with. Lets watch the expenses due to this change for a month once it
gets implemented, and then take stock of the situation. For now, lets
reduce one more extra work for developers, ie, marking Verified flag.

So, My take is:

Lets make serialized smoke + regression a reality. It may add to overall
time, but if there are failures, this has potential to reduce overall
machine usage... for a successful patch, the extra few minutes at present
doesn't harm as many of our review avg time is around a week.

Absolutely! This is critical for us to be inclusive community.

Most of these are doing the same thing, make dist, make install, make rpms.
but on different arch and with different flags. To start with, we can do
these also sequentially. That way, infra team needn't worry about some
parallel, some sequential jobs.

I would say, lets get started on these changes.
