09:00:29 <saggi> Hi everyone
09:00:32 <xiangxinyong456> hello
09:00:43 <yuval> hey
09:00:47 <Leon_Wang> hello
09:01:37 <saggi> Are we waiting for anyone?
09:01:41 <zhonghua-lee> hi
09:01:48 <saggi> I haven't seen yinwei in meetings for a while
09:02:52 <saggi> OK
09:03:05 <saggi> #topic Delete 'crontab' time format for time trigger, and support RFC2445 (zengchen)
09:03:21 <saggi> zengchen is not here.
09:03:29 <yuval> pinged him in channel
09:03:56 <zengchen> sorry i am late
09:04:35 <saggi> What about $topic?
09:05:03 <zengchen> delete crontab time format and support rfc2445 only.
09:05:15 <saggi> why remove the existing one. Why not have both?
09:05:55 <saggi> zengchen ?
09:05:58 <zengchen> from the point of user, he don't care use which format to describe the time.
09:06:32 <zengchen> and from the point of horizon, it use only one time format.
09:06:34 <chenying__> hi
09:06:45 <zhonghua-lee> zengchen: can I say crontabl is part of RFC2445?
09:07:34 <zengchen> zhonghua-lee:RFC2445 is enough, and more appropriate than crontab.
09:08:23 <zhonghua-lee> zengchen: so, could you please simplly explain the difference "crontab" and RFC 2445, I think some guys confuse this
09:08:54 <zengchen> zhuanghua-lee:ok
09:09:22 <zhonghua-lee> zengchen: thanks
09:10:03 <chenying__> delete crontab. I think it is ok.
09:10:08 <zengchen> IMO, crontab can be used in simple use cases, and can not describe more complex time than rfc2445.
09:10:48 <saggi> xiangxinyong456: What about UI for this ?\
09:11:02 <xiangxinyong456> if crontab is deleted，I guess we need to do some work in horizon
09:12:16 <zengchen> xiangxinyong456:whatever use rfc2445 or crontab or others, horizon should choose one from them.
09:12:47 <xiangxinyong456> yeah we have already use crontab.
09:13:10 <xiangxinyong456> why not keep the crontab?
09:13:14 <zengchen> xiangxinyong456:if so, we would better choose an appropriate one.
09:13:19 <zhonghua-lee> xiangxinyong456: can UI support both of them?
09:13:54 <xiangxinyong456> zhonghua-lee: it is not neccerray
09:13:55 <saggi> It's just a metter of having a format combo box
09:14:10 <yuval> IMO we should keep support for crontab for now. Later we can decide to change the UI for iCal and maybe remove crontab
09:14:22 <chenying__> chenzeng  think crontab format  is  port of rfc2245 time  format.
09:14:50 <chenying__> part
09:14:58 <xiangxinyong456> but the user does not care whether we use crontab or rfc
09:15:13 <saggi> xiangxinyong456: They have different features
09:15:23 <xiangxinyong456> yeah
09:15:46 <zhonghua-lee> xiangxinyong456: if users do not care, why to change the UI?
09:15:48 <zengchen> chenying__:I don't know whether crontab is part of rfc, I think if we want to support more complex time format, it better to use rfc.
09:15:51 <saggi> So they need different UIs for the different limitations\features
09:16:04 <xiangxinyong456> but we should users evevy day,every week, like this
09:16:25 <xiangxinyong456> the ui is the same
09:16:36 <saggi> zengchen: We are not arguing with that. But since we have the option to specify time format we can have both for now. We just need to make sure we have a proper UI for both.
09:16:56 <xiangxinyong456> but we need to do some transform between ui and time format
09:17:18 <xiangxinyong456> the ui is same
09:17:36 <zengchen> saggi:but i think we don't need to add a box for user to choose time format, they don't care.
09:17:53 <xiangxinyong456> zengchen: +1
09:17:58 <saggi> zengchen: I understand
09:18:24 <saggi> OK, than just make sure the UI moves to the new format as well.
09:18:58 <xiangxinyong456> yeah
09:19:14 <zengchen> saggi:at present, zhangshuai has submitted a patch to support rfc2445, so the last work is about UI.
09:19:28 <saggi> great
09:20:12 <zhangshuai___> https://review.openstack.org/#/c/359711
09:20:13 <zengchen> saggi:so we change to rfc some time later?
09:20:25 <xiangxinyong456> <yuval> IMO we should keep support for crontab for now. Later we can decide to change the UI for iCal and maybe remove crontab
09:20:33 <saggi> zengchen: When the UI changes
09:20:33 <xiangxinyong456> i agree yuval
09:20:56 <zengchen> saggi & xiangxinyong456:ok
09:21:04 <zhangshuai___> +1
09:21:32 <xiangxinyong456> if the rfc is stable, we could move into it in the ui
09:21:41 <saggi> OK, than we have both for now and try and migrate the default to be rfc2245
09:22:00 <xiangxinyong456> no problem
09:22:03 <zengchen> saggi:great.
09:22:14 <saggi> #topic Rename window September 2nd (yuvalbr)
09:22:49 <yuval> Well, infra team has designated September 2nd for the rename window
09:22:57 <yuval> it means a downtime for gerrit
09:23:14 <yuval> after that, smaug repositories will be renamed to karbor
09:23:23 <saggi> We need to be ready with patches to commit so that after the switch we can immediately fix all the paths and make sure everything still works.
09:23:33 <xiangxinyong456> good news
09:24:07 <yuval> the rename window happens on Friday
09:25:10 <yuval> also, all our communications move to #openstack-karbor
09:25:42 <xiangxinyong456> ok
09:25:47 <zhangshuai___> ok
09:26:53 <yuval> that's it
09:26:55 <zengchen> yuval:all patches should be merged before that.
09:27:06 <yuval> zengchen: which patches?
09:27:37 <zengchen> not merge now
09:27:53 <yuval> zengchen: what?
09:29:36 <zengchen> yuval:for example, the patches are reviewing now should be merged before that time.
09:30:18 <yuval> zengchen: the rename shouldn't affect patches pending review
09:30:35 <saggi> They will move to the new repo
09:30:40 <zengchen> yuval:ok
09:31:00 <saggi> That whole point of the downtime is to migrate all of the information
09:31:49 <zengchen> saggi:so we should spend more time to review patches, right?
09:32:09 <saggi> zengchen: You should always do that :)
09:32:26 <zengchen> saggi:ok, understand.
09:32:28 <yuval> zengchen: anything specific?
09:32:59 <zengchen> yuval:i have several patches pending review, so i have a little worry.
09:33:59 <yuval> zengchen: I see most of them had a new version in the latest day. are they stable now?
09:35:15 <zengchen> yuval: most of them is stable, i am trying to submit a patch about updating scheduled operation.
09:35:38 <yuval> zengchen: if something is not stable, mark with workflow -1, so we'll know to wait with the review
09:36:02 <zengchen> yuval:understand, i will do it. thank you.
09:37:28 <saggi> OK
