maishskgood afternoon.11:49
maishskI have a heat template using a AWS::CloudFormation::WaitConditionHandle11:50
maishskand it seems that the AWS::CloudFormation::WaitConditionHandle is creating an OpenStack project for each and every handle.11:51
maishskAnyone have an idea?11:51
*** links has joined #heat11:55
thervemaishsk, There is one per stack, it ought to reused it12:02
thervereuse12:02
*** code-R has joined #heat12:03
maishsktherve: is there a reason why it would not be re-using?12:03
*** Guest49924 has quit IRC12:03
maishskEven more along that - why is it creating a project?12:04
*** code-R_ has joined #heat12:05
therveIt needs credentials to authenticate to heat12:06
therveSo every handle is creating a user inside the stack project12:06
*** sorantis has joined #heat12:07
*** code-R has quit IRC12:08
maishskbut one second - it creates it in the stack project - or creates a new OpenStack project12:08
*** fragatina has joined #heat12:09
therveIn the stack project12:09
therveI literally just said that :)12:09
maishskthen why would I be seeing this as a project in openstack project-list ?12:13
maishskhttp://pastebin.com/Cj38zxz912:14
therveI don't know how many stacks do you have12:16
*** catintheroof has joined #heat12:17
maishskI am seeing a new project for each and every stack that I launch12:22
maishskThe user is defined as an admin12:23
ramishramaishsk: when therve says 'stack project' it's a new project per stack and the project of the user who is creating the stack.12:23
maishsk(for other reasons)12:23
ramishraand not the project12:23
*** misty-cloud has joined #heat12:23
thervemaishsk, Yes, there is one project per stack12:24
therveNot one per handle as you said12:24
maishskAnd each stack has to have its own - there no way to tell it use a specific project? (or tell to use a shared one? )12:25
maishskI have approximately 30-50 stacks - which means I am going to have 30-50 different projects?12:25

ramishratherve: Have you seen this https://bugs.launchpad.net/nova/+bug/1480698?12:37
openstackLaunchpad bug 1480698 in oslo.db "MySQL error - too many connections" [Undecided,Invalid]12:37
therveramishra, Nope12:37
thervemaishsk, Why is that an issue?12:37
maishskI am not sure if it is even an issue12:38
*** fragatina has quit IRC12:38
maishskIs it?12:38
ramishraI did some tests this morning, it seems with max_overflow as default, if we reduced executor_thread_pool_size it seems to work fine.12:38
*** ccamacho is now known as ccamacho|lunch12:40
ramishratherve: I was wondering why having increased number of resources in the stack would increase the connections.12:40
ramishraAs per my understanding we would have one db engine(pool) per worker process, no?12:41
ccard_Are the parts in an OS::Heat::MultipartMime type resource processed sequentially?12:43
thervemaishsk, No12:43
maishsktherve: thanks12:44
therveramishra, Because if you have more resources, you have more check_resource calls. And then basically one thread and one db connections each12:44
*** code-R_ has quit IRC12:44
therveUnless https://review.openstack.org/400155 lands12:44
ramishrayeah, but it would be limited by pool size + overflow12:44
*** code-R has joined #heat12:45
ramishraso for 8 cpu machine we would have 8*(5+40) connections.12:45
ramishraand it would be much less than 102412:46
ramishraNot sure if my logic is flawed, but I see connections increasing steadily and hitting 1024.12:48
therveOh yeah you're missing something12:50
therveramishra, https://review.openstack.org/#/c/262374/12:50
therveSo at least it's 64, not 4012:51
thervePlus, those are shared with other services12:51
ramishrayeah that would be 8*(5+64) max, right?12:52
ramishrayeah, I agree about the other services.12:52
ramishraBut in my testing, without any activity from other services it just keeps on increasing.12:52
ramishraI mentioned in the begining that I reverted that patch.12:53
ramishra'max_overflow as default'12:53
therveAh sorry12:55
therveWell maybe there is a bug then12:55
ramishraI was thinking may be connections/sessions are not garbage collected quickly.12:55
therveIt's possible it takes some time to close them12:55
ramishraso mysql thinks the connections are still open.12:55
ramishraI was thinking we should probably land this https://review.openstack.org/#/c/330800/12:57
therveIs that related?12:58
ramishraI mean it's the new way of using oslo.db enginefacade12:59
ramishrawe need more work to convert the other stuff.12:59
ramishraso we don't have to handle sesions and connections etc.13:00
ramishraI think we don't have to keep the session in the context.13:00
