| persistentstorag | Hi! Where would I write persistent data to? Let's say I ran my seedbox as a collection of snaps. Looking for something similar to docker data volumes, or a home directory. | 11:11 |
| ogra_ | SNAP_APP_DATA_PATH or SNAP_APP_USER_DATA_PATH point to writable spaces in the snap env (the latter only for binaries a user can execute, the foremer is the writable and persistent package dir) | 11:12 |

| sergiusens_ | kyrofa, here's a small present https://github.com/ubuntu-core/snapcraft/pull/230 | 13:34 |
| sergiusens_ | good morning | 13:34 |
| === sergiusens_ is now known as sergiusens | ||
| kyrofa | sergiusens_, good morning! | 13:34 |
| kyrofa | sergiusens, wait... why didn't we hit that before? | 13:35 |
| sergiusens | kyrofa, I have no clue; maybe check if /usr/bin/python exists on 15.04 | 13:36 |
| sergiusens | which it might as well | 13:36 |
| kyrofa | Yeah that's what I'm assuming | 13:36 |
| kyrofa | It does indeed exist | 13:36 |
| kyrofa | But it's been removed on xenial eh? | 13:36 |
| sergiusens | hah, there we go; yeah, cloud-init moved to python3 so that might have removed the dep | 13:37 |
| sergiusens | kyrofa, it still fails though | 13:37 |
| sergiusens | kyrofa, [rosrun] Couldn't find executable named listener below /snaps/ros-example.sideload/IKKNUNfbERGD/opt/ros/indigo/share/beginner_tutorials | 13:37 |
| sergiusens | kyrofa, I see talker under lib though (it is looking for it in share) | 13:38 |
| sergiusens | kyrofa, this part of ros is black magic to me | 13:38 |
| kyrofa | Yeah it shouldn't be looking in there... odd | 13:38 |
| sergiusens | kyrofa, any clues where to look? | 13:39 |
| kyrofa | sergiusens, no that's never happened to me before | 13:43 |
| kyrofa | sergiusens, I do plan on looking into this by the way... just trying to knock out the .snaps first | 13:44 |
| kyrofa | sergiusens, I feel like you're procrastinating on those slides... ;) | 13:44 |
| sergiusens | kyrofa, sure, maybe we land this PR as is then? It does fix the specific bug :-P | 13:45 |
| sergiusens | kyrofa, slides ... right and look at the time | 13:45 |
| sergiusens | darn | 13:45 |
| kyrofa | sergiusens, hahaha | 13:45 |
| kyrofa | ogra_, is this still valid? "Note: the snappy update command will currently not work with Raspberry Pi 2 images. It requires hosting the device tarball on a system-image server, which is not yet available." | 13:46 |
| sergiusens | kyrofa, use mvo's recently announce pi2 images (if you are looking into rolling) | 13:47 |
| kyrofa | sergiusens, no I'm just trying to figure out if that comment it out of date. People are suggesting not to use Core on the rpi2 due to it | 13:51 |
| sergiusens | kyrofa, I suppose with mvo's announcement that is indeed out of date for rolling | 13:54 |
| mvo | kyrofa: pi2 in rolling will update just fine | 13:55 |
| mvo | kyrofa: well, unless there are nasty bugs of course | 13:55 |
| kyrofa | sergiusens, does autopilot automatically update all installed snaps? | 13:55 |
| kyrofa | mvo, excellent thank you | 13:55 |
| sergiusens | kyrofa, it is of course not production ready, but it is tinkerer ready | 13:57 |
| kyrofa | sergiusens, right, of course | 13:57 |
| === chihchun is now known as chihchun_afk | ||
| sergiusens | kyrofa, one more https://github.com/ubuntu-core/snapcraft/pull/231 | 14:09 |
| elopio | kyrofa: so, what I'm thinking is that after you are done with owncloud you would enjoy packaging syncthing ^_^ | 14:57 |
| kyrofa | elopio, how have I not heard of that? | 14:57 |
| elopio | hipster synching. | 14:59 |
| kyrofa | Hahaha | 14:59 |
| kyrofa | elopio, this has been an excellent experience though. I feel like it's really pushing snapcraft | 15:03 |
| peacememories | question: is there an api for snappy that e.g. a framework could use to control it? | 15:05 |
| kyrofa | peacememories, control what exactly? | 15:12 |
| peacememories | installing .snap files, for example | 15:12 |
| kyrofa | peacememories, can you explain what you have in mind? | 15:13 |
| kyrofa | peacememories, e.g. you just described webdm. Have you used that? | 15:13 |
| peacememories | not yet, no. gimme a second, looking into it | 15:14 |
| kyrofa | peacememories, the short answer to your question is yes. The longer answer is that you may be trying to do something that has already been done :) | 15:14 |
| peacememories | what i'm trying to achieve: control what version of a software is installed on the device (stereomatching engine on a stereo camera) | 15:15 |
| peacememories | remotely, of course | 15:15 |
| kyrofa | peacememories, via something other than SSH I assume? | 15:15 |
| peacememories | yes | 15:16 |
| kyrofa | peacememories, GUI only? | 15:16 |
| peacememories | actually without any gui, i guess. there will be a gui, but that will probably be built in house | 15:16 |
| kyrofa | peacememories, yeah, look at webdm. You may like that. If it doesn't do exactly what you want consider contributing to it | 15:17 |
| kyrofa | peacememories, failing that, yes, there's an API you can use | 15:17 |
| kyrofa | peacememories, Chipaca is your best resource regarding that, I think | 15:17 |
| kgunn | mvo: i'm sure you have plenty to do, but wondering if you might want to jot down an idea for u-d-f, when i create my core image...i always need to resize afterward (my mir stuff is meaty) | 15:18 |
| kgunn | wondering if you might add a size option | 15:19 |
| kyrofa | kgunn may be something you want to mention to sergiusens. He's been talking about revamping u-d-f | 15:20 |
| peacememories | btw, does snappy support having multiple versions of a software installed, with one being active? | 15:21 |
| kgunn | sure | 15:22 |
| peacememories | that's definitely neat | 15:23 |
| peacememories | still trying to wrap my head around where to put everything and how to manage software on an embedded snappy device | 15:23 |
| kgunn | oh peacememories lol, sure @letting sergiusens know | 15:23 |
| kgunn | but i suppose the answer is still yes to that | 15:23 |
| peacememories | oh^^ | 15:23 |
| kgunn | peacememories: but i should let the experts speak | 15:24 |
| kyrofa | peacememories, kgunn perhaps the better answer is "kinda"? I'm not sure you can have a newer version installed while the older is active | 15:24 |
| kgunn | right... | 15:24 |
| kgunn | it always takes the latest | 15:24 |
| kyrofa | peacememories, but the old versions remain there, yes | 15:24 |
| kyrofa | peacememories, to allow for rollbacks | 15:24 |
| peacememories | hmm | 15:25 |
| kyrofa | Chipaca will know if there's a way around that | 15:26 |
| peacememories | maybe what i'm trying to do would be abusing the snappy architecture. seems a bit like it | 15:28 |
| peacememories | i'm trying a bit hard to make this work, mainly because i don't know any other small embedded distros with AB-partition update capabilities | 15:29 |
| kyrofa | peacememories, what are you trying to accomplish with the multiple versions? | 15:30 |
| peacememories | kyrofa, the ability to quickly choose the running version of a software via a management interface | 15:30 |
| peacememories | i could do a workaround that saves the .snap files on the system and uses a local install | 15:30 |
| mvo | kgunn: hi, there is a --size option :) is it not working? | 15:31 |
| kyrofa | peacememories, that may be a better idea | 15:31 |
| kgunn | mvo: doh! | 15:31 |
| kyrofa | peacememories, I'm afraid anything else may result in trying to fight snappy | 15:31 |
| peacememories | our semantics would probably be the same as 'rollback' anyway, but the current idea for the management interface doesn't mesh too well with that :/ | 15:31 |
| kyrofa | peacememories, there's a problem though | 15:32 |
| peacememories | hm? | 15:32 |
| kyrofa | peacememories, upgrades copy the old version's data, rollbacks go back to the old version of the data. Uninstalling and installing a new one won't do either-- data would be empty | 15:32 |
| kyrofa | peacememories, does the .snap in question have data? | 15:33 |
| peacememories | not right now, no. a different snap might, though | 15:33 |
| kyrofa | peacememories, something to keep in mind then | 15:34 |
| peacememories | i'm assuming a .snap install of a newer version doesn't register as an upgrade? | 15:34 |
| kyrofa | peacememories, hmm... good question. Sideloaded I'd say no, but if not sideloaded I'm not sure what happens. You may even get a "already installed" type of error. mvo do you know the answer to that? | 15:35 |
| kyrofa | Well, I'm not sure how you'd accomplish what you're trying without sideloading, so perhaps the answer to your question is no | 15:36 |
| kyrofa | peacememories, though it's important to point out that copying the data is as easy as cp -r over ssh | 15:37 |
| elopio | oh sad day. | 15:37 |
| kyrofa | elopio, what's up? | 15:38 |
| elopio | stgraber: the lxd import started failing on travis. | 15:38 |
| elopio | Image manifest: http://cloud-images.ubuntu.com/server/xenial/20160105/xenial-server-cloudimg-amd64.manifest | 15:38 |
| elopio | error: HTTP Error 404: Not Found | 15:38 |
| kyrofa | elopio, is that what you're using in the tests? | 15:38 |
| elopio | that URL indeed returns a 404. Do I need to update something? | 15:38 |
| elopio | kyrofa: I'm just asking for the daily xenial. | 15:39 |
| kyrofa | change the datetime to current? | 15:39 |
| kyrofa | elopio, datestamp, rather | 15:39 |
| kyrofa | elopio, http://cloud-images.ubuntu.com/xenial/current/xenial-server-cloudimg-amd64.manifest | 15:39 |
| elopio | kyrofa: I'm not sure where to put the date. The command is "lxd-images import ubuntu xenial --stream daily --alias ubuntu" | 15:41 |
| kyrofa | elopio, oh... | 15:41 |
| kyrofa | elopio, stgraber question then, I suppose? | 15:41 |
| elopio | pindonga: good I gave you an ETA of friday. The branch was all green for a couple of hours, then we had the travis outage, and now this. | 15:42 |
| elopio | it's cursed. | 15:42 |
| pindonga | :( | 15:42 |
| kyrofa | elopio, have you built a cmake part before? | 15:47 |
| mvo | kyrofa: uh, sorry, was in a meeting. is the question still open? | 15:57 |
| kyrofa | mvo, I don't think so, no worries :) | 15:57 |
| elopio | kyrofa: I don't think os. | 15:58 |
| elopio | *so | 15:58 |
| === chihchun_afk is now known as chihchun | ||
| stgraber | elopio: xenial simple stream is busted, the cloud team is on it | 16:02 |
| kyrofa | elopio, how would you feel if we added some sort of installflags option to the autotools/cmake/make plugins? | 16:05 |
| kyrofa | elopio, I really want a make -j8 here :P | 16:05 |
| kyrofa | elopio, compiling some things single threaded take forrrreeeever. | 16:06 |
| * kyrofa looks at mysql | 16:06 | |
| elopio | stgraber: ah, thanks for the info. I'll wait. | 16:06 |
| elopio | kyrofa: I would like that. But if feels weird to hardcode j8 on your yaml. | 16:07 |
| kyrofa | elopio, can you think of a better way? | 16:07 |
| elopio | kyrofa: it would be really cool to be able to pass command line args from the snapcraft binary to the plugin. But sounds messy too. | 16:07 |
| kyrofa | Hmm... yeah that sounds more involved. But I agree | 16:07 |
| elopio | maybe something like --plugin-flag autotools:-j8 | 16:08 |
| elopio | I have the feeling that Sergio will hate this :) | 16:08 |
| kyrofa | Me too. I can imagine installflags being useful for things other than things as hardware-dependent as -j though. For instance, the apache installation has a number of "install this elsewhere" type of flags | 16:09 |
| kyrofa | Wow that sentence had terrible grammar. I'm sorry | 16:09 |
| kyrofa | elopio, so maybe since that gets us part way there, it's a better solution for now? | 16:10 |
| elopio | I think I got it. Maybe a config file? I wonder how juju does it. | 16:10 |
| elopio | I mean, I think I got what you meant on that sentence, not that I got the solution. | 16:10 |
| kyrofa | Heh | 16:11 |
| elopio | kyrofa: if you pass -j8 and you have less than 8, it will just do less parallelization right? So it's not terrible to hardcode it. | 16:11 |
| elopio | then you can plug it to a fancier way to receive the value. Config or command line, or smart guess. | 16:12 |
| kyrofa | elopio, right, it'll make 8 threads and they just won't be able to work concurrently | 16:12 |
| kyrofa | elopio, so you think the installflags sounds okay? If the .snap author wants to hardcode something, it's his problem | 16:14 |
| elopio | fgimenez: https://xkcd.com/1629/ That's you explaining your jenkins farm :D | 16:14 |
| fgimenez | elopio, not enough tools IMO but accurate anyway :D | 16:17 |
| kyrofa | elopio, have you ever listened to explanations of openstack? http://cube-drone.com/comics/c/alien-geometries | 16:17 |
| elopio | haha, yes. Swipes left for tinder. lol. | 16:18 |
| peacememories | hm, the path to deploy snappy as a 'firmware' is a lot more clear than the path to keep said firmware up to date | 16:20 |
| kyrofa | My favorite is "Trove -> Mostly just sits there." I never could figure that thing out | 16:20 |
| kyrofa | peacememories, how so? | 16:30 |
| kyrofa | peacememories, keeping it up to date is one of the biggest upsides to snappy | 16:31 |
| peacememories | to keep my snaps up to date seems to require them being in the official store though | 16:32 |
| peacememories | ideally i'd like to have the ability to do a firmware upgrade a la digital cameras | 16:32 |
| peacememories | which would basically be "update the oem snap", which doesn't seem to be possible | 16:33 |
| kyrofa | peacememories, completely offline? | 16:33 |
| peacememories | that's one of the requirements, yes | 16:33 |
| peacememories | there's two update modes for us atm: a managment server tells sends the software to the device and tells it to update | 16:34 |
| peacememories | or a user plugs in a usb with an update | 16:34 |
| kyrofa | peacememories, I know there are ongoing discussions about private stores, but that's something I don't know much about (I'd refer you to bueno, but he doesn't seem to be around at the moment) | 16:35 |
| peacememories | our structure is not really set in stone yet, but can't come up with many other ideas | 16:35 |
| peacememories | yeah, i've read about private stores being 'on the horizon' | 16:36 |
| kyrofa | peacememories, yeah you're not the only person that's looking for that. I'm just not sure what the state of it is exactly | 16:36 |
| kyrofa | peacememories, I suggest you send out a snappy-devel mailing list post about it | 16:36 |
| kyrofa | peacememories, that way you can be sure the right eyes see it rather than trying to wait until they're on IRC | 16:37 |
| peacememories | i'll do that. also i'll need to test whether using snappy install *.snap can upgrade packages | 16:37 |
| peacememories | thanks for your help so far =) | 16:37 |
| kyrofa | peacememories, no problem, sorry my knowledge is a bit limited :) | 16:38 |
| peacememories | i wish there was more info out there about deploying embedded systems^^ this is my first voyage into the field and it's pretty daunting | 16:39 |
| kyrofa | peacememories, the problem you often run into is that embedded systems are almost always proprietary | 16:40 |
| kyrofa | peacememories, so not a lot on google | 16:40 |
| peacememories | indeed | 16:40 |
| kyrofa | peacememories, but there are some open-source embedded communities, like the rpi, gumstix, and ubuntu core | 16:41 |
| kyrofa | peacememories, lots of "learn by doing" in your future ;) | 16:41 |
| peacememories | yep. not sure if i'm looking forward to that^^ | 16:42 |
| kyrofa | peacememories, not the fastest way to learn, but one of the best | 16:43 |
| peacememories | i should probably write a blog about this stuff. add a bit to the information out there, even if it's just 'how not to do it' | 16:43 |
| kyrofa | peacememories, definitely | 16:44 |
| === kickinz1 is now known as kickinz1|eod | ||
| peacememories | okay, so when i install with --allow-unauthenticated my snap gets installed as sideloaded | 17:20 |
| kyrofa | peacememories, right | 17:20 |
| peacememories | and i assume the only signatures snappy accepts are from the ubuntu store | 17:21 |
| * zyga posted https://github.com/ubuntu-core/snappy/pull/326 | 17:21 | |
| zyga | this lets capability types hand out bits of security for variou security subsystems | 17:21 |
| zyga | another approach at the security aspect | 17:22 |
| kyrofa | peacememories, indeed, which leads back to the private store | 17:22 |
| * peacememories sighs | 17:22 | |
| zyga | jdstrand: ^^ perhaps you can have a look | 17:22 |
| zyga | jdstrand: it's different from the earlier approach | 17:22 |
| zyga | jdstrand: but I think this is closer in intent to what hwaccess was doing than before | 17:22 |
| zyga | jdstrand: one thing I'd love to know about is how device nodes are pushed to the dev namespace today (who's doing that) | 17:23 |
| zyga | jdstrand: because nothing in the design handles that yet | 17:23 |
| === chihchun is now known as chihchun_afk | ||
| sergiusens | kyrofa, hey, you are indeed right that there is no shebang; there is although an "embedded shebang" | 17:58 |
| kyrofa | sergiusens, huh? :P | 17:59 |
| kyrofa | sergiusens, I mean, no #! or anything | 17:59 |
| kyrofa | sergiusens, compiling mysql is taking so long I have time to look into this all of a sudden :P | 18:00 |
| sergiusens | kyrofa, http://paste.ubuntu.com/14497580/ line 30 there is originally /usr/bin/python | 18:01 |
| kyrofa | sergiusens, indeed, and I have more lines than you between 1-3 | 18:02 |
| sergiusens | kyrofa, which may indicate that I fixed this incorrectly | 18:02 |
| kyrofa | sergiusens, with another /usr/bin/python. But still no #!, which means the regex won't catch it... no? | 18:02 |
| jdstrand | zyga: I haven't looked at the code yet, but to answer your question: hw-assign creates /etc/udev/rules.d/70-snappy_hwassign_foo.mvo.rules and /var/lib/snappy/apparmor/additional/foo.hwaccess.yaml | 18:02 |
| sergiusens | kyrofa, or maybe is too greedy | 18:03 |
| sergiusens | kyrofa, I'll look at it now | 18:03 |
| kyrofa | sergiusens, alright. I'm looking into the stupid share thing now | 18:03 |
| jdstrand | zyga: then hwaccess updates the profile for what is in /var/lib/snappy/apparmor/additional/foo.hwaccess.yaml | 18:03 |
| sergiusens | kyrofa, what share? | 18:03 |
| jdstrand | zyga: s/profile/security policy/ | 18:03 |
| sergiusens | kyrofa, getting rid of the ros plugin altogether? :-) | 18:03 |
| kyrofa | sergiusens, ha! I mean launching out of share instead of lib | 18:04 |
| sergiusens | kyrofa, k, it might be related | 18:04 |
| zyga | jdstrand: oh, thanks I didn't know about the udev rule! | 18:04 |
| zyga | jdstrand: I'll add that | 18:04 |
| jdstrand | zyga: then on app launch, ubuntu-core-launcher sees if /etc/udev/rules.d/70-snappy_hwassign_foo.mvo.rules exists. if it doesn't, it just launches the app in the normal way. if it does, it creates a device cgroup and puts the devices in /etc/udev/rules.d/70-snappy_hwassign_foo.mvo.rules into an app-specific cgroup | 18:05 |
| jdstrand | zyga: in this manner, apparmor prevents reading devices when no hardware is assigned, and cgroups allow the device to be used by the app | 18:06 |
| zyga | jdstrand: so /var/lib/snappy/apparmor/additional/foo.hwaccess.yaml + /etc/udev/rules.d/70-snappy_hwassign_foo.mvo.rules | 18:06 |
| zyga | jdstrand: do we need to run a command to recompile anything after those two are made? | 18:06 |
| jdstrand | in an ideal world we wouldn't use a cgroup for this and just rely on apparmor, but that is the parser performance conversation we had before | 18:06 |
| jdstrand | zyga: yes, snappy needs to regenerate the apparmor policy if /var/lib/snappy/apparmor/additional/foo.hwaccess.yaml is created/updated/removed | 18:07 |
| zyga | jdstrand: how is that done (regenerate) | 18:08 |
| jdstrand | zyga: but it shouldn't regenerate the policy if /var/lib/snappy/apparmor/additional/foo.hwaccess.yaml is unchanged | 18:08 |
| jdstrand | (the regeneration is the slow (relatively) operation) | 18:08 |
| jdstrand | zyga: see AddHWAccess(). it calls regenerateAppArmorRules(snapname) | 18:09 |
| zyga | jdstrand: ok, I'll follow that along | 18:10 |
| zyga | jdstrand: I'll try to get apparmor support sufficient to blink LEDs on raspberry pi tomorrow | 18:10 |
| zyga | (without hwaccess) | 18:10 |
| jdstrand | zyga: hwaccess.go should be fairly easy to follow with the above context | 18:10 |
| jdstrand | zyga: cool! | 18:11 |
| sergiusens | kyrofa, this is what I have in the catkin part originally http://paste.ubuntu.com/14497678/ | 18:16 |
| kyrofa | sergiusens, yeah, same | 18:17 |
| sergiusens | kyrofa, ah, the regex wipes line 4 and 5 :-) | 18:18 |
| sergiusens | err 3 and 4 | 18:18 |
| kyrofa | sergiusens, how is that possible? It looks for # followed by !. The .* is perhaps too greedy, but what about that? | 18:19 |
| sergiusens | kyrofa, yeah, it should be a broken file in the end | 18:20 |
| kyrofa | sergiusens, no... it shouldn't match lines 3-4 at all! | 18:21 |
| kyrofa | sergiusens, right? | 18:21 |
| sergiusens | oh because of the ! | 18:21 |
| kyrofa | Right | 18:21 |
| sergiusens | kyrofa, more so, the regex matches nothing on this file ;-) | 18:24 |
| kyrofa | sergiusens, exactly! | 18:24 |
| sergiusens | kyrofa, the first line says it is autogenerated though; any idea if that is during packaging or during unpack or what? | 18:25 |
| kyrofa | sergiusens, I expect it's during compilation | 18:25 |
| kyrofa | So during packaging | 18:25 |
| sergiusens | kyrofa, of ros itself | 18:25 |
| kyrofa | Right | 18:25 |
| sergiusens | right | 18:25 |
| kyrofa | Figured out the rosrun problem | 18:27 |
| kyrofa | More shebangs | 18:28 |
| kyrofa | sergiusens, time for a grep... what are we dealing with here now that python2 is no longer on the image... | 18:28 |
| elopio | woohoo, lxd working again. | 18:29 |
| sergiusens | kyrofa, maybe take over the MP and I'll get to the other things | 18:29 |
| sergiusens | elopio, nice | 18:29 |
| kyrofa | sergiusens, perhaps instead of patching just _setup_util, the post build step should be one big search/replace. Yeah I got it | 18:29 |
| sergiusens | kyrofa, I hope the second sentence was a mid reply and not you writing to yourself ;-) | 18:41 |
| kyrofa | sergiusens, :P | 18:41 |
| sergiusens | kyrofa, I myself seem to have started out the day with the wrong foot :-) | 18:44 |
| kyrofa | sergiusens, hahaha | 18:44 |
| kyrofa | sergiusens, you got your car at least? | 18:45 |
| sergiusens | kyrofa, yeah, I got there and it seemed there was a screw up on when I was supposed to pick it up | 18:48 |
| sergiusens | at least it was all checked up; just missing the final "car wash" | 18:48 |
| kyrofa | sergiusens, that sounds annoying | 18:48 |
| sergiusens | kyrofa, yeah, and no ranting emails from ogra_ to read on my phone :-) | 18:49 |
| sergiusens | kyrofa, now that this passsses (with many s's), care to look https://github.com/ubuntu-core/snapcraft/pull/231 ? | 19:59 |
| sergiusens | kyrofa, it will make testing the listener and talker easier | 19:59 |
| enoch85 | kyrofa, here? | 20:28 |
| kyrofa | sergiusens, fixed the bug, though I hit another-- the caps have changed on rolling | 20:31 |
| kyrofa | sergiusens, network-listener is no longer default? | 20:31 |
| sergiusens | kyrofa, ask jdstrand for the equiv :-) | 20:31 |
| kyrofa | jdstrand, on 15.04 if all I use is the network I don't have to do anything regarding caps. That seems to have changed on rolling? | 20:32 |
| sergiusens | kyrofa, what error do you get? | 20:33 |
| jdstrand | if you want to use the network as a client, you should use network-client | 20:33 |
| kyrofa | sergiusens, a bad syscall :P | 20:33 |
| kyrofa | sergiusens, bind | 20:33 |
| jdstrand | if you want to use the network as a service, use network-listener | 20:33 |
| kyrofa | jdstrand, oh interesting-- network-client is the default? | 20:34 |
| jdstrand | network-client is given if you don't specify anything | 20:34 |
| jdstrand | if you start specifying other stuff, you need to specify it | 20:34 |
| jdstrand | too | 20:34 |
| kyrofa | jdstrand, what is the difference between the client and listener? | 20:34 |
| kyrofa | jdstrand, are you just assuming clients won't bind? | 20:35 |
| kyrofa | Oh duh, thinking binaries, sorry | 20:35 |
| kyrofa | jdstrand, understood, thanks | 20:35 |
| jdstrand | np | 20:35 |
| jdstrand | there is also unix-listener if you need to bind to a unix socket | 20:35 |
| kyrofa | jdstrand, awesome :) | 20:35 |
| jdstrand | (network-listener is for binding to a network socket) | 20:36 |
| jdstrand | at this point, they aren't different, but they will be soon | 20:36 |
| kyrofa | jdstrand, does network-listener encompass network-client? | 20:37 |
| jdstrand | kyrofa: no. there are some apparmor rules that are different | 20:39 |
| jdstrand | network-listener might be all you need now, but that is a different question | 20:39 |
| kyrofa | jdstrand, hmm. I guess we'll find out | 20:40 |
| jdstrand | (ie you may not need the rules that differentiate them) | 20:40 |
| jdstrand | in 16.10 and later they will be more different | 20:40 |
| kyrofa | jdstrand, is there a reason /proc/pid/status is disallowed in the profile? | 20:47 |
| kyrofa | jdstrand, rather, not present | 20:48 |
| jdstrand | kyrofa: that's queued for stable, fixed in 16.04.12 on rolling | 20:49 |
| kyrofa | jdstrand, ah excellent-- mysql needs it | 20:49 |
| kyrofa | jdstrand, any chance we can get that back in 15.04? | 20:49 |
| kyrofa | jdstrand, or is that what you meant by stable? | 20:50 |
| jdstrand | that is what I meant be stable | 20:50 |
| jdstrand | by* | 20:50 |
| wxl | so i have problems creating images with ubuntu-device-flash and i greped the entire code for it for the word "partition" since my problem is "issues when partitioning" and there's no result. any clues as to where else i can start looking? | 20:50 |
| kyrofa | jdstrand, any ETA for that? | 20:51 |
| jdstrand | kyrofa: maybe I can get it in real quick since a stable image is queued to be built | 20:51 |
| kyrofa | jdstrand, you would be my hero | 20:51 |
| jdstrand | kyrofa: it is in https://launchpad.net/~snappy-dev/+archive/ubuntu/image/+packages. hopefully I got it in in time | 21:01 |
| kyrofa | Thanks jdstrand! Sorry for the rush, but I really appreciate it | 21:02 |
| jdstrand | I already had it prepared | 21:02 |
| jdstrand | I was waiting for feedback on another thing that I would add depending on what they said | 21:02 |
| jdstrand | so I just uploaded what I had. no biggie :) | 21:03 |
| kyrofa | jdstrand, excellent :) | 21:03 |
| jdstrand | I thought it weird that access never came up before last week | 21:04 |
| * jdstrand shrugs | 21:04 | |
| kyrofa | jdstrand, how can I track that so I know when I can snappy update to get it? | 21:04 |
| kyrofa | jdstrand, more and more people using it, I would guess | 21:04 |
| jdstrand | sure, it just seems like that access was so basic | 21:05 |
| jdstrand | anyhoo | 21:05 |
| kyrofa | jdstrand, indeed | 21:05 |
| jdstrand | well, mvo is doing a stable update for something else | 21:05 |
| jdstrand | I think there might be a manifest somewhere for snappy stable images, but I can never seem to remember where it is | 21:05 |
| jdstrand | if the images updates, do 'dpkg -l|grep ubuntu-core-security' and see if 15.04.12~ppa15 is installed (that is what I would do if I didn't want to ask anyone) | 21:06 |
| kyrofa | jdstrand, alright, thanks :) | 21:08 |
| sergiusens | kyrofa, is this what I need http://wiki.ros.org/image_view ? | 21:11 |
| kyrofa | sergiusens, yes | 21:12 |
| sergiusens | kyrofa, iow, I need a trusty machine, right? | 21:12 |
| kyrofa | sergiusens, it's in their repos as well if you want to just setup ROS on an lxc | 21:12 |
| kyrofa | sergiusens, that's safest anyway | 21:13 |
| sergiusens | kyrofa, does it expose it over the web? I'll setup a trusty lxc | 21:13 |
| sergiusens | kyrofa, I just setup a 16.04 ubuntu core laptop to test | 21:13 |
| sergiusens | so I am also making your snap 16.04 ready ;-) | 21:13 |
| kyrofa | sergiusens, nahh nothing runs by default unless you run it | 21:14 |
| kyrofa | sergiusens, ooo, living on the edge! | 21:14 |
| sergiusens | kyrofa, of course | 21:14 |
| sergiusens | kyrofa, right, I'm confused by this messaging Nodelet version of image_view. Brings up a display window for a sensor_msgs/Image topic. | 21:15 |
| kyrofa | sergiusens, the face_detector publishes a sensor_msgs/Image | 21:15 |
| kyrofa | sergiusens, so image_view subscribes to that and displays it in a window | 21:15 |
| sergiusens | kyrofa, right, I will need my lxc to have knowledge of such windowing system :-) | 21:16 |
| kyrofa | sergiusens, I just do reverse-X | 21:16 |
| sergiusens | kyrofa, as in ssh -Y or -X ? | 21:16 |
| kyrofa | sergiusens, lxc GUIs were too painful for me | 21:16 |
| kyrofa | sergiusens, yeah, ssh -X | 21:16 |
| rickspencer3 | does anyone know which GPIO pins work on the rpi2 "out of the box"? | 22:20 |
| rickspencer3 | arg, never mind, I was holding it upside down :/ | 22:26 |
| elopio | rickspencer3: like with the pins facing the table? ;) | 22:50 |
| rickspencer3 | something like that | 22:50 |
| rickspencer3 | no, I guess I should have said "I was holding it backwards" | 22:50 |
| rickspencer3 | the arduino is designed for people like me, they label the pins :) | 22:51 |
| * rickspencer3 wonders if getting some dinner might help | 22:53 | |
| kyrofa | elopio, hahaha, funny image | 22:57 |
| elopio | rickspencer3: I got this https://www.adafruit.com/products/2314 and then I realized I had to learn to solder first :) | 22:57 |
| kyrofa | elopio, ROS stuff runs on xenial now with this: https://github.com/ubuntu-core/snapcraft/pull/232 | 23:14 |
| elopio | kyrofa: cool. I just left PITA style comments. | 23:28 |
| kyrofa | elopio, thanks! :) | 23:29 |
