*** bigdogstl has joined #openstack-swift00:52
brianclineor, possibly more likely, some convoluted series of events led to data being put into a place where it shouldn't be00:52
claygeverytime I think about "improbable" I *feel* like that means *possible* - but then I do some math - and I can't seem to convince myself the entropy of the universe has been exhausted.  It's weird state of suspended disbelief.00:55

claygbriancline: there's this -> https://github.com/openstack/swift/blob/master/swift/obj/diskfile.py#L230700:56
*** bigdogstl has quit IRC00:56
claygwhich at least says if there is an existing object '/a/c/o' at has xyz, then later another object '/a2/c/o' is directed into that same hashdir the diskfile just barfs on itself.00:57
claygI always assumed it was not possible unless you have access to the swift.conf hash secrets - and bunch of GPU and superadmin write access to any possible collision path (a preimage attack would be significantly more work - and limited to data w/i your same own account)00:59
clayg*possible to hit that code path00:59
brianclineclayg: yeah, the object server catches that exception and throws a 403, which is exactly what I'm seeing01:00
claygbriancline: oic!01:01
brianclinewhich is good, it at least hits the brakes on the request, just made me go "huh?" seeing a 403 in object server logs01:01
claygif you swift-object-info that object *in* that hashdir does the location information indicate it should be somewhere else entirely?01:01
brianclinefor a colliding PUT, the proxy ends up writing it to handoffs, which accept it01:02
claygoh neat!  then rsync hates you :'(01:02
brianclinehm lemme check. i did notice swift-get-nodes for the same path returns some strange disparities01:02
claygwell...  gotta bounce01:03

gordchi folks, was wondering if something changed in swift master recently that requires any deployment changes? we use pifpaf to test against swift and seeing this now: https://github.com/jd/pifpaf/issues/7713:31
gordcin case youre interested, this is how we start swift: https://github.com/jd/pifpaf/blob/master/pifpaf/drivers/swift.py#L117-L13213:32

jrichligordc: is the 'fakedisk' with insufficient storage supposed to be used here?  were you running a failure test case?13:38
tdasilvagordc: I think you might be running into the same issue cschwede fixed recently for tripleo: https://bugs.launchpad.net/tripleo/+bug/171845413:40
openstackLaunchpad bug 1718454 in tripleo "undercloud, swift returns 503 in undercloud install" [Critical,Fix released] - Assigned to Christian Schwede (cschwede)13:40
openstackgerritMerged openstack/swift feature/deep: Add test for reversed listings  https://review.openstack.org/50578413:40
gordcjrichli: nope. pifpaf is basically just temporarily setups and runs a service so it can be tested against13:40
acolesgordc: looks like mount check is failing for account HEAD, this did change recently https://review.openstack.org/#/c/466255/13:41
patchbotpatch 466255 - swift - Make mount_check option usable in containerized en... (MERGED)13:41
acolesbut looks like the change should help not fail13:41
cschwedegordc: tdasilva is right, looks like the same issue we had in tripleo13:41
gordctdasilva: that does look quite similar. i'll take a look at it13:41
gordcthanks for the pointers everyone, a lot more progress than me just looking blindly at code :)13:41
cschwedegordc: see also this lp entry: https://launchpad.net/bugs/171845413:42

cschwedeacoles: ^^ it's the follow up that merged a few days ago, which broke quite a few CIs...13:43
gordccschwede: if i create folder, does it work for older versions of swift too?13:43

zaitcevtdasilva, clayg: Thanks, guys. If we could make it even later, it would be okay, but 18:00Z is fine.17:57
zaitcevI mean it could be even better.17:57
zaitcevI mostly made the patch presentable for the PTG, dropped most offensive XXX-es and tested it.17:57
tdasilvazaitcev: maybe 20:00 UTC?17:57
zaitcevtdasilva: even better17:58
tdasilvaok, will send invite out17:58
claygI think later starts to keep Alistair up pretty late (8pm) - but he does tend to be flexible17:58

zaitcevMy wife has an oral surgery in the morning on 9/26, but she's digging the ground with her hove to drive herself to the surgeon and back, as Russians say.18:00
claygwhy are we doing it *at all* on Tuesday then!?  :P18:02
zaitcevI don't want to postpone it forever. At least I want you guys to have a good look at what's going on. Otherwise maybe the whole thing is garbage and I don't even know about it.18:03
claygsure, but like... Thursday :P18:05

tdasilvazaitcev, clayg: I picked those Tuesday times really based on trying to maximize highest number of people based on the doodle table, but we can be flexible...20:31
claygzaitcev: can you "fix" your availability then so that tdasilva can pick times for when people are acctually willing to be there?20:33
tdasilvayeah, maybe we can move for later in the week so you don't have to worry about Tuesday and your wife surgery20:34
zaitcevAny other day is okay.20:38
tdasilvamaybe Wed at 1400UTC?20:38
