_mup_cleanup of tests to directly show invocation of [relation-* args] commands06:29
_mup_    Because of repeated issues in the hooks being changed or out of sync with the tests I took the time to remove many of the hook scripts that existed only to capture the arguments or calling convention around a relation-get/set/list command. This makes the tests easier to read and verify.06:29

kapilniemeyer, what do you think about a preallocation option for some number of machines on bootstrap, as a cli/config option14:21
niemeyerkapil: Sounds neat14:22
kapilie. a min machines in config14:22
kapilniemeyer, i'm trying out tiny natty images atm, i think some preallocation might make initial service deploys a bit faster14:22
niemeyerkapil: Yeah, definitely.. and there's no real issue with it that I can think of.  It's just increasing the pool14:23

kapilyeah.. micro instances are working now14:28
SpamapSI've had instance_type set to t1.micro for a while. :)14:38
SpamapSthey spin up about 2x as fast as m1.small14:38
SpamapSand, given that they can be re-started as a bigger instance type.. they seem an ideal starting type. :)14:38
SpamapSbtw, it would be good to be able to specify a different ami for the bootsrap node and the others.. apparently LXC on lucid is fairly crackful.14:41
SpamapSso the ability to say "bootstrap me on natty, but then run everything else on lucid" is desirable.14:42

niemeyerSpamapS: We'll be moving to Natty after next week (beta FTW)14:56
kapilSpamapS, yeah.. lxc was one the kicker for me on the move to natty.. i've been trying it out in maverick the last few days, via libvirt (the integration of which is broken even with openstack ppas).15:04
kapilSpamapS, i'm in progress on making the ami configurable via environments.yaml15:05
SpamapSI think its a common situation that bootstrap will have different machine providers and arguments..15:07
kapilSpamapS, sure, the individual environments have configs.. although i think your suggesting bootstrap should only do one environment at a time?15:07
kapilwhich all sounds good15:08
SpamapSIt would be good if it was easily overridable just for bootstrap is all.15:09
SpamapSLike.. "bootstrap me in ec2, then use the lxc provider"15:09

bcsallerkapil: in what way? I'm curious what wasn't version generic16:52
kapilniemeyer, on debug hook one problem i noted is that we can't easily set debug for install or service hooks, because we validate the unit name.. so we don't have much to get the debug setup before the hook executes, it probably should wait on the unit's existence with a few minutes for a timeout.16:54
kapilbcsaller, not sure exactly.. i should try it in the debugger, the wordpress side didn't get a second db-relation-changed fired for the mysql modify was all i noticed. 16:55
niemeyerkapil: Hmm.. how do we validate the name atm?16:57
kapilniemeyer, we verify a the unit's service and unit name, so we can dereference to a machine16:58
niemeyerkapil: Hmm16:58
niemeyerkapil: But how do we debug a unit before we know its name?16:58
_mup_Bug #741890 was filed: Better support for debugging install/start hooks <Ensemble:New> < https://launchpad.net/bugs/741890 >16:58
niemeyerkapil: Or do I misunderstand what you mean?16:59
kapilniemeyer, no.. i think you've got the underlying question here16:59
kapilniemeyer, previously we had relatively determinstic ordering, with global ordering, its not predictable per se... well it is predictable but not nesc. obvious.17:00
kapiler. global sequence on unit names17:00
niemeyerkapil: I see17:00
kapilso you do ensemble debug-hooks mysql/0  and ensemble deploy mysql17:00
niemeyerkapil: But then, even if we were able to predict the unit name, it feels like a bad approach in general17:01
niemeyerkapil: Like winning a typing race :)17:01
kapilniemeyer, we can predict with fair certainty the next name of the unit internal to the api.17:01
kapilso perhaps mysql/next 17:01
niemeyerkapil: It feels like a much better approach would be to do that at deploy time17:01
niemeyerkapil: ensemble deploy --debug-hooks ...17:01
kapilas a unit name denoting debug the next unit of this service17:02
niemeyerand then hook up17:02
niemeyer"hook up" is an ideal term in that case, I guess ;-)17:02
kapilniemeyer, hmm so deploy would drop into a debug shell after waiting for the machine startup?17:02
kapilthat sounds pretty nice17:02
niemeyerkapil: No, it would only set a flag there17:03
niemeyerkapil: We don't want to be copying everything over from debug-hooks I think17:03
kapilniemeyer, i was just thinking calling out to some refactor in debug-hooks17:03
niemeyerkapil: It'd put the unit in debug mode, and then we can run ensemble debug-hooks after the fact at our leisure17:03
kapilwell currently debug-hooks is ephemeral..17:03
niemeyerkapil: Hmmm.. can we still an ephemeral node? :-)17:04
kapilsort of17:04
kapilwe can steal the session id if we save it...17:04
niemeyerHmm.. that's full of edge cases IIRC17:04
kapiland the time between the commands is less than session timeout17:04
kapilniemeyer, yeah.. can of worms17:05
niemeyer(from my gozk playing)17:05
kapilmuch easier to call into a refactored debug-hooks from deploy17:05
kapilalthough its gets a little messy when deploy could mean a whole suite of services and units... we should only debugthe top level one.. but then we start getting formula that specify min units >1 and get ambigious.17:07
kapilniemeyer, the only alternative i can come up with is symbolic naming for units denoting a  temporal/state marker.. like mysql/next17:11
kapilthat could be consumed by debug-hooks17:11
kapilbut combining them sounds nice17:11
niemeyerkapil: Hmmm!17:12
niemeyerkapil: There may be an alternative17:12
niemeyerkapil: We might make the node non-ephemeral in that specific case17:12
niemeyerkapil: So debug-hooks borrows ownership from it, and explicitly kills it when exiting17:13
kapilniemeyer, perhaps.. i'm a little reluctant to give up the ephemeral safety blanket. that sort of change would work though. doesn't really get away from the ambiguity of doing it directly in deploy17:14
kapilif we're going to set it in deploy, its not clear what we gain by not dropping the user directly into the debug shell they just requested when its ready17:15
niemeyerkapil: Well, we're giving up on it purposefully.. the problem is precisely that we don't want to node to be removed when deploy exits17:15
niemeyerkapil: and I don't see how there's any ambiguity in that case17:15
kapilits a future ambiguity we can address latter.. but ignoring that for the moment, why not just drop them straight from deploy into the debug shell if they requested it.17:16
niemeyerkapil: Because it's ambiguous would be one reason, but otherwise I can't think of any great reason not to either.17:17
kapilniemeyer, i think i prefer that.. beyond the peristent debug node, we have to change debug-hooks to reconcile against existing state any new cli arguments17:18
kapilhmm.. as a result of the perisstent17:19
niemeyerkapil: Sounds good.  Just for curiosity sake, what do you mean regarding reconcile?17:20
kapilniemeyer, the debug-hooks cli takes unit name hook-match-filter.. if the --debug-hooks  flag on deploy leaves a persistent node, then we have to reconcile current args vs. stored state.17:21
niemeyerkapil: I see, ok17:21
kapilprobably just not accepting args in that case.. or just erroring out.. its syntax.. but its consistency too ;-)17:22
jimbakeris something like this legal? relation-set port= 17:23
niemeyerjimbaker: I have vague memories of defining that this would internally remove the variable17:25
kapiljimbaker, i think so17:26
niemeyerjimbaker: Either way, yeah, it sholud17:26
kapilit won't kill the variable just an empty value for it17:26
kapili think we ended up loosing a good way to unset values atm17:26
niemeyerkapil: This should probably remove the variable, at least as far as those command line tools are concerned17:27
kapilthere's a dictionary merge syntax on the hook context, but the api doesn't expose it17:27
niemeyerkapil: Since "relation-get port" with it empty or unset is effectively equivalent17:27
kapilniemeyer, what about  a magic unset variable?17:27
jimbakeragreed on removing the variable, since that's the sh convention17:27
niemeyerkapil: What about it? 8)17:27
kapileither works.. i'm just wondering if there are cases where an empty but existant value is valid17:28
kapilfair enough its simpler to do for now17:28

kapilniemeyer, i had a question for you regarding https://code.launchpad.net/~hazmat/ensemble/formula-upgrades-spec/+merge/53898 #1120:34
kapilso a service may have multiple relations and the formula not the name for all of them.. mysql for example, might have a dozen dbapp-relations.. 20:35
kapilpointing to different services20:35
kapilrelation-list is designed to iterate over all units.. so relation-list dbapp-relation would list all units20:35
kapili'm just thinking it might make more sense to deal with those relations one by one, via iteration of the relations.20:36
