jreevestherve: thanks15:59
therveNo problem15:59
jreeveswait, isn't that the Mitaka template version?15:59
*** vijendar has quit IRC15:59
therveOh sorry you said newton16:00
thervejreeves, We don't have a version for that yet16:00
jreevesah…ok. No wonder I couldn't find it on my own then :)16:01
*** e0ne has joined #heat16:01
thervejreeves, Why do you need it, out of curiosity?16:01
*** sridhar_ram has joined #heat16:03
jreevesI had a resource plugin add that was supposed to go into mitaka, but because of a dependent neutronclient commit that got pushed to N-1, the resource will be pushed too…so I need to update the template version16:03
therveHum16:04
therveI see your point, but resources are not really tied to template version16:04
jreevesI'm making a wild guess that the template version will be something like 2016-10-14 based on the release schedule, but wanted to make sure16:04
jreevesno, they're not, but there's items in the test and the spec that have it in there16:05

skraynev_zaneb: hi.19:50
skraynev_zaneb: are you around?19:50
zanebskraynev_: hey19:50
skraynev_zaneb: so. I have some interesting info about concurrent signals.19:51
skraynev_zaneb: first of all thank you for the comments for first patch.19:51
zanebnp19:51
skraynev_I will fix them tomorrow. They looks ok and I agree with changes (new decorator, removing old unnecessary code and moving method to resource object)19:52
skraynev_so it's good part ;)19:52
zaneb\o/19:52
skraynev_about second patch19:52
skraynev_yeah. I will change seq :) it is just my habbit to use it in bash :)19:53
*** aaronmehar has joined #heat19:53
skraynev_*habit19:53
*** pt_15 has joined #heat19:53
skraynev_The issue, which I mentioned on review is. I used & in wrong way, so as result bash parsed it in wrong way19:54
skraynev_and always complained on unexpected ";"19:54
*** akuznetsov has quit IRC19:54
skraynev_so I just used brackets19:54
skraynev_like for ... ; do (something &); done19:55
skraynev_and it works correct19:55
zanebah, ok19:55
zaneb"do something & done" also works19:55
skraynev_so all signals now go to background and as stevebaker suggested create more parallel load19:55
zanebwhich I never would have guessed before today :)19:55
skraynev_zaneb:  :)19:56
skraynev_so the bad part....19:56
skraynev_fix does not work with such load :) lol19:56
stevebakerhaha19:56
zanebdoh!19:56
skraynev_the first issue, which I saw and mostly fixed is a case:19:56
stevebakerskraynev_: is it hitting the retry limit? 25 concurrent signals is a lot19:57
skraynev_stevebaker: in the current variant - yes19:57
skraynev_when we get metadata, then make "merge" , and then (before write new_metadata) we get resource from db again and.. then write new meta19:58
skraynev_so there is a window between first metadata_get and second getting resource from db19:58
skraynev_while we merge data we spend some time and as result object can get new metadata before we start write new "updated"19:59
skraynev_is it clear ?19:59
skraynev_I just worried, that may explain it in bad way :)19:59
zaneboh, yeah, that's not cool20:01
stevebakerskraynev_: are you saying that it needs to be implemented in a way that needs only one metadata_get?20:01
zanebwe can't do a second get20:01
zanebwe should use the data from the first get20:01
zaneb(i.e. the atomic_key and engine_id from the original get)20:02
skraynev_stevebaker: zaneb: mostly... My idea was follow: I added check before we write data in follow way if current_metadata != rs.rsrc_metadata  - I raise Concurrent Trans error20:02
*** jcoufal has quit IRC20:03
skraynev_http://paste.openstack.org/show/490787/20:03
skraynev_like here ^20:03
skraynev_and....20:04
skraynev_ it works for 30 signals now , but ... with retry count ~= 2020:04
skraynev_instead of 1120:04
skraynev_then I decided to check it on 70 signals :)20:04
zanebskraynev_: no, that's not sufficient20:05
skraynev_and it again met retry-limit20:05
*** Raj1 has quit IRC20:05
stevebakeras long as the error propagates back to the signaller with a sensible status code, hitting the retry limit should be fine. It can be up to the caller to try again20:06
skraynev_zaneb: the logging show, that in case of 70 signals we have totally ~ 410 re-try requests due to db read/write error (when there is no updated rows)20:06
skraynev_and about 60 retry due to using now fresh metadata (for condition , which I pasted above)20:06
skraynev_of course this data will increase for more signal numbers20:07
zanebskraynev_: it's sufficient for writing lots of things going through update_metadata()... I believe it's unsafe if you have writes coming from other places20:07
skraynev_zaneb: so what do you suggest? I am not sure, that got your idea from last comment20:09
skraynev_stevebaker: so do you suggest do it infinitive, while we don't get desired result ? i.e. without limit on retry ?20:10
zanebskraynev_: do only one get. pass the engine_id and the atomic_key and any other info you need to update_metadata(). don't do a get inside update_metadata().20:11
zanebskraynev_: 10 retries are more than sufficient IMHO20:12
skraynev_zaneb: hm... I think if I do only one get and then try to write this data it can be outdated ?20:14
skraynev_and as result I will overwrite correct metadata from previous requests, which updated it before while I workong on preparation new meta based on old meta snapshot ;)20:15
* skraynev_ read what he wrote ... facepalm20:15
zanebiff you do only one get and then try to write the data it can never be outdated, because of the atomic key20:15
skraynev_zaneb: sound like I don't know something about atomic key20:16
skraynev_ :)20:16
skraynev_could you give a short clarification how it works   or I go read code myself ;)20:16
zanebit gets incremented on every change, and the update query filters on it not having changed, so if something else modifies the data then 0 rows will be updated and we will retry20:17
skraynev_aha! got it.20:19
skraynev_thx you saved my time20:19
