harlowjaamrith ah that one20:18
harlowjahavne't opened that in a while, ha20:18
harlowja*haven't20:18
harlowja@amrith do u want to take that over?20:18
harlowjai'm ok with that20:18
amrithharlowja, I wanted to chat with you about it20:18
harlowjaor i can abandon and u can make a better one20:18
harlowjak20:18
amrithand the history of this20:18
amrithyou recall the conversation in the summit about this20:18
amrith(I hope)20:19
harlowjawe had a summit????!???20:19
harlowjalol20:19
amrithwell, I think we did. or at least I went to barcelona for some reason :)20:19
harlowjayes, i remember (mostly)20:19
amrithI'm looking at the code there and it seems like a nice place to do things20:19
harlowjaright20:19
harlowjait was meant to be some really basic stuff that would skip the prior attempts at it20:20
amrithbut the approach there seems to be that the computation of the checksum is in oslo20:20
amrithI had been contemplating having a callback to the caller for the computation and verification of the checksum20:20
amrithnot sure if that's the right thing to do or not20:20
amrith6 of one, half dozen of the other kind of thing20:20
harlowjaright20:21
amrithI'm fine doing it this way but then there needs to be some mechanism to safely get the secret down to the serialize_msg method20:21
harlowjaright, how hard is a callback to pull off20:21
*** sileht has quit IRC20:21
amrithif I want to do the checksum at the place you have it, it makes it identically hard20:22
harlowja:)20:22
harlowjaright20:22
amrithwhether you have to pass a callback or a secret, it is a parameter that has to make its way down20:22
harlowjaagreed20:22
amrithbut it is much more attractive for me to be able to do the computation of checksum in oslo messaging than doing it all in the project (trove in my case)20:23
amrithhowever I am also wondering about upgrade implications20:23
*** ansmith has quit IRC20:23
harlowjaya, its hard to start enforcing that across versions20:24
amrithi'd hoped I could have a flag in trove that indicated that for one release (co-existance) there would be no enforcement of signatures20:24
amriththat would be hard to if I bury the logic in oslo.20:24
amrithso I was hoping to put my thoughts together on this and maybe have a chat with you and or the right folks. I'm not so much concerned about your patch or the abandonment or taking it over. more the issue now is what is the approach and why did past attempts fail?20:24
harlowjaif its a callback though u at least could have a callback named oslo.messaging.validation.warn_but_not_enforce20:24
harlowjafor example20:24
harlowjaor oslo.messaging.validation.enforce20:25
amrithyes, that's correct; and it would be more customizable.20:25
amrithso to figure out history, I've reached out to some of the names in old reviews that were merged and abandoned20:25
harlowjakk20:25
amrithand the links that dims provided20:25
harlowjaya, i don't even remember all the history :-P20:25
harlowjait goes back quite far, ha20:25
amrithNow, if I want this all to happen for ocata; what's the deadline?20:25
harlowjabefore even that review20:25
amrithor should I not even bother20:25
amrithis this where you start laughing hysterically :)20:26
harlowjai'm ok with doing it, as long as its backwards-compat it doesn't seem harmful20:26
harlowjaso imho do it20:26
harlowjathough as u can see https://review.openstack.org/#/q/topic:bp/trusted-messaging20:27
harlowjai don't even remember some of that history, lol20:27
harlowjagoes back to 2013, woah20:27
amrithok, it is easier to deal with backward compat down in oslo; i.e if the code doesn't know what to do with the signature, it'll drop it. in trove, that would be harder; the receiver would puke on the unknown argument if the version of code didn't have something to take it out before calling the actual RPC20:27
*** sileht has joined #openstack-oslo20:28
amrithin my decorator method, the decorator is the one which would remove the signature from the parameters before calling the actual RPC method.20:28
harlowjaya, i feel like a validation callback (and one that signs also?) seems ok, one that can be a no_op by default20:28
amrithyes, the no-op would mean that the app is ignoring the validation mechanism; which is fine. up to the app to do.20:29
harlowjaya20:29
amrithsounds good, I'll chug along on this path and see where it takes me.20:29
amriththanks harlowja20:29
harlowjanp20:29
harlowjaamrith let me know what history u find out20:29
harlowjamaybe just burned to many people out trying that, idk20:30
harlowjahttps://review.openstack.org/#/c/128926 is another one to20:30
harlowjaseems like really complex, idk20:31
amrithhere's the list of links I've made so far20:31
amrithhttps://gist.github.com/amrith/44f1527037e5fd68e4daec13401aa05020:31
amrithadded your latest one at the end20:31
harlowjakk20:32
harlowjaseeing how http://www.grpc.io/docs/guides/auth.html does this is also interesing to think about20:32
amrithyes, and there were also some attempts to implement the standard rpc auth mechanism (ala rfc5531) along the way.20:34
harlowjaya, write a mini-book about this when u are done20:34
amrithrecognized those and recall some old scars with that ;)20:34
harlowjaor a kids book20:34
harlowjamaybe a mini-kids-book20:34
harlowjawith nice pictures20:34
*** lpetrut has quit IRC20:34
amrithhave you noticed, on the kids-book theme, that most childrens books are actually nightmarish? mary had a little lamb and someone took it away, little miss muffet was attacked by a spider, humpty dumpty broke his head. Do you know of a nursery rhyme that ends happily?20:35
harlowjathe auth+oslo.messaging one20:35
harlowjaobviously will end happy20:35
