timburketorgomatic: thinking more about _initialize -- where's the transaction happening? i mean, i see conn.commit() just after self._initialize(...), but i don't see where we *begin*05:42
timburkethe closest i could find was https://github.com/openstack/swift/blob/2.17.0/swift/common/db.py#L245-L246 -- but that sounds like we're doing the *opposite* of wrapping everything in a transaction?05:43
timburkehrm. but then we already *do* have renaming logic down around https://github.com/openstack/swift/blob/2.17.0/swift/common/db.py#L299-L305 ...05:44
timburkei'm really not sure how that row disappeared :-(05:45

timburkeit's interesting... we don't have this trigger https://github.com/openstack/swift/blob/2.17.0/swift/container/backend.py#L11405:59
timburkeeven though we have the view right above it!05:59
kota_timburke: doesn't the trigger exist in the empty db? In my correct db, `select * from sqlite_master;` shows the trigger to me.06:32

rabelhi there. i have a fresh all-in-one openstack deployment with kolla-ansible, but i get a 503 when i query the swift-proxy . i had a look at https://wiki.openstack.org/wiki/TroubleshootingSwift , but i'm not sure if it is up to date. kolla did not deploy an auth-server afaics and there is no auth-server.conf either. how can i fix this?10:31
rabelor if this is not too easily solved: what is the recommended way to test swift? devstacK?10:33

notmynamerabel: good morning. are you still having issues with 503s?15:32
rabelnotmyname: the mentioned swift installation is still not working, yes. i'm using a devstack to do some tests right now, so it's not critical for me though15:33
notmynamerabel: what do the logs say when you get the 503?15:37
*** silor has joined #openstack-swift15:39
rabelnotmyname: sorry, it seems to have stopped logging, so i had to search a little bit. http://paste.openstack.org/show/664808/ this is only siwft-proxy-server logs15:42
rabelthere are similar errors from swift-object-expirer15:43
onovyrabel: your account server is not running15:46
notmynamerabel: is the account server running on that host?15:46
onovyor running on differrent port15:46
onovycompare ring with reality, test by telnet/curl/wget15:46
notmyname`swift-recon --validate-servers {account, container, object}` will check the servers with the reality of the ring15:47
rabelok, the swift servers seem to listen on wrong IPs15:54
rabeli think i changed the ip at some point and rerun kolla-ansible destroy and kolla-ansible deploy. might that be the problem?15:55
rabelor maybe kolla assumes that i use certain ip addresses when building the rings15:57
rabelanyways, you helped me. i think i can fix it somehow15:57

acolesclayg: we thought it might be nice if the current root db was always called <hash>.db but I think that might be harder to achieve than giving the root db a new name like <hash_root>.db18:44

persiaGood day.  The PTL nomination period is ending in a little over 4 hours, and there has still not been a nomination for a Swift PTL.  If anyone is around and could nominate a PTL, that would be great.  Given the continuity of leadership, I suspect there is little doubt, but without a nomination, the process is more complicated.19:27

claygonovy: timburke: I think using the exception as flow control in quarantine is a weird pattern20:46
claygwe go into this function and there's no return statement - it's not clear from the outside that we don't plan to ever come back... it's weird.20:47
timburkeclayg: that was *already* true of possibly_quarantine -- either we were going to reraise the already-caught exception, or we were going to quarantine and raise a new DatabaseError20:54
clayg+1 totally agree - i've noticed this before20:55
