| Chipaca | pitti: you got a bit? | 15:12 |
| ogra_ | or a byte :) | 15:15 |
| mvo | pitti: hi, can I ask silly systemd questions again? so I have a snappy system (wily) here that tells me startup has finished but I get no getty on tty1, only on 2-6. should I be concerned? | 15:21 |
| cmk | any1 get snappy GUI on snappy desktop to work? | 15:38 |
| ogra_ | cmk, i think tedg did a QML app on top of Mir once | 15:40 |
| ogra_ | and no. desktop is still a bit away | 15:40 |
| tedg | Yeah, but that wasn't snappy desktop. | 15:41 |
| tedg | Just snappy core. | 15:41 |
| ogra_ | well, it was a snappy GUI :) | 15:41 |
| ogra_ | (app) | 15:41 |
| ogra_ | ppisati, hmm ... i just accidentially flashed a rpi image that still had 3.19 ... ran snappy upgrade which worked fine, but after reboot i end up with: http://paste.ubuntu.com/12886195/ | 15:42 |
| ogra_ | doesnt even uncompress 4.2 | 15:42 |
| ppisati | ogra_: 99% you have to update the dtb | 15:43 |
| cmk | k thx | 15:43 |
| ogra_ | ppisati, hrm | 15:43 |
| ogra_ | thats tricky since the dtb doesnt actually liuve in the device tarball but in the oem (bootloader) snap | 15:44 |
| ogra_ | also then we wouldnt be able to roll back | 15:44 |
| ogra_ | mvo, sergiusens ^^^ thats a problem | 15:45 |
| ogra_ | (nothing we need to tackle today but the RPi HW reqs wont work with the current snappy design as soon as we get a major bump of the kernel) | 15:45 |
| ppisati | ogra_: don't we handle the rollback via the a/b thing? | 15:46 |
| ogra_ | and thanks to vfat i cant just use a link to the a or b dtb | 15:46 |
| ogra_ | ppisati, yes, after the blob loaded the dtb | 15:46 |
| ppisati | ogra_: and since a/b doesn't work in rpi2 due to the bcm bootloader | 15:46 |
| ogra_ | a b works fine | 15:47 |
| ogra_ | this is why we have uboot | 15:47 |
| ogra_ | it handles all that | 15:47 |
| ogra_ | but the blob loads the dtb before we load uboot | 15:47 |
| ogra_ | and it doesnt load it from a or b either but from /boot | 15:47 |
| ppisati | ogra_: right, so my point was that we hanlded going back and forth using two different kernels/initrd/dtb | 15:47 |
| ogra_ | not on the Pi | 15:48 |
| ppisati | right | 15:48 |
| ogra_ | because the dtb is loaded by the blob | 15:48 |
| ppisati | since we use the bcm bootloader | 15:48 |
| ogra_ | yeah | 15:48 |
| ppisati | so that feature is broken there | 15:48 |
| ogra_ | which isnt acceptable for a fully supported snappy arch | 15:48 |
| ogra_ | rollback needs to work | 15:49 |
| * ogra_ sighs | 15:49 | |
| ogra_ | the blob also doesnt knwo if we boot a or b ... because the logic for that happens later | 15:50 |
| tedg | vmayoral: Trying to think about how we explain better the whole deb vs. snap thing on the mailing list. Here's my thought dump as a graphic, thoughts? https://usercontent.irccloud-cdn.com/file/26hwfJt2/deb-vs-snap | 15:52 |
| vmayoral | hi tedg, that's good one | 15:54 |
| vmayoral | tedg: in a general way, that's what Snappy (AFAIK) is doing | 15:54 |
| ogra_ | ppisati, oh ! ignore me, thats probably a red herring ... i just see it installed the -generic kernel during the upgrade :P | 15:55 |
| vmayoral | tedg: ROS-wise, there's the issue of "extending" a robot's behavior based on other snaps. I've been doing a bit of thinking on that but haven't been able to come up with anything solid but a few hacks | 15:56 |
| vmayoral | tedg: will keep thinking though :) | 15:56 |
| ogra_ | so the hard hang at uncompressing definitely comes from that | 15:56 |
| ogra_ | (wont fix the dtb issue indeed) | 15:56 |
| === chihchun is now known as chihchun_afk | ||
| vmayoral | tedg: thanks for clarifying the OSRF claim btw, appreciate that. | 15:56 |
| tedg | vmayoral: Cool, no problem, sorry I misspoke originally. | 15:59 |
| vmayoral | tedg: I'm interested about your thoughts on the snappy environment for ROS | 15:59 |
| tedg | Overally I'm worried people are mis-understanding Snappy and so we're not communicating. | 15:59 |
| tedg | Overall | 16:00 |
| tedg | Feel like we need some new language there. | 16:00 |
| tedg | vmayoral: For ROS I'm kinda leaning towards thinking about ROS2 and keeping ROS1 contained in a snap. Which we can then support for ROS2 (i.e. bundle the bridge) | 16:01 |
| vmayoral | tedg: that'll be sweet and pretty smart. ROS 2 is still on its infancy but it'll take over really soon and will define the next 10 years of robotics | 16:03 |
| vmayoral | (that's my personal thinking at least) | 16:03 |
| vmayoral | tedg: my feeling is that there're some things that quite don't fully match, how do you see the following scenario: "Erle-Spider is delivered based on Snappy with a single snap containing roscore and our ROS packages. A developer in Japan wants to create a visual odometry snap and make money out of it. How can he do it without hacking the snap released by us?" | 16:04 |
| tedg | vmayoral: I'll start by saying I'm relatively new to ROS :-) | 16:05 |
| tedg | vmayoral: But it seems to me that's basically the problem ROS2 is trying to solve. | 16:05 |
| tedg | vmayoral: In that in ROS1 you need all kinds of access and assumptions about the underlying system to do that. | 16:05 |
| tedg | vmayoral: Where ROS2 seems to think about associations and connection points between robots, which could be internally as well. | 16:06 |
| vmayoral | tedg: i'd say the same applies to RO2. ROS 2 replaces the communication layer by DDS and adopts a standard but several problems still will apply with the snappy aproach | 16:07 |
| vmayoral | let me put it this way: | 16:07 |
| vmayoral | tedg: "Erle-Spider is delivered based on Snappy with a single snap containing roscore and our ROS packages to make it move around. In a later stage, Erle Robotics deliver a 'visual_odometry' snap that provides odometry information to developers exposed in a new ROS node. A developer in Japan wants to create an app with Erle-Spider an for that he wants to use visual the odometry snap released by Erle Robotics." | 16:09 |
| vmayoral | How do you see this happening? | 16:09 |
| ogra_ | your odometry data would have to be exposed on a (domain|network) socket ... from where he picks it up | 16:10 |
| vmayoral | ogra_: but since snaps can't depend on snaps, there should be a way to enforce it, shouldn't it? | 16:10 |
| tedg | vmayoral: So I think that there will have to be some amount of frameworks, and frameworks are going to have to know something about the applications that use them. | 16:11 |
| vmayoral | ogra_: i mean, right, UDP comms should be allowed between snaps, but dependencies aren't AFAIK. | 16:11 |
| ogra_ | right | 16:11 |
| tedg | vmayoral: For instance, an app on the desktop needs to install and setup its icon. Same idea. | 16:11 |
| tedg | vmayoral: There'll be a certain amount of "handshaking," declarative of course, between the two. | 16:12 |
| vmayoral | tedg: mmm well that convinces a bit. Not sure, i'd like to do more thinking about it | 16:19 |
| vmayoral | what seems clear to me are the benefits of adopting Snappy on a final (commercial) product. | 16:19 |
| vmayoral | The fact that you guys deal with security is actually a great complement to the lack of it in ROS | 16:19 |
| tedg | Yes, I was a little shocked by that when I started researching how ROS works :-) | 16:27 |
| ogra_ | well, dont blame ROS | 16:28 |
| ogra_ | after all this is how *all* embedded development worked for the past 20-30 years | 16:28 |
| ogra_ | (which is why it is so easy to hack into nuclear power plants or industrial controllers today :P ) | 16:29 |
| tedg | Let's not talk about that, I want to sleep tonight :-) | 16:36 |
| ogra_ | haha | 16:37 |

| kgunn | tedg: ok, back to our discussion yday, configflags is supported by cmake....so i'd suppose i type something like snapcraft build Boost_DIR=./parts/mir-demo-server/install/usr/lib/x86_64-linux-gnu/ | 16:47 |
| kgunn | just checking incantation syntax | 16:47 |
| kgunn | what would it be | 16:47 |
| tedg | kgunn: No, no, a field in the snapcraft.yaml | 16:47 |
| tedg | kgunn: plugin: cmake\nconfigflags:\n-Boost_DIR=./parts/mir-demo-server/install/usr/lib/x86_64-linux-gnu/ | 16:48 |

| kgunn | tedg: lol @whitespace | 16:48 |
| kgunn | thanks | 16:48 |
| kgunn | tedg: so i added like so https://pastebin.canonical.com/142330/ but got a | 16:53 |
| kgunn | Issues while validating snapcraft.yaml: mapping values are not allowed here on line 18 of snapcraft.yaml | 16:53 |
| kgunn | so possibly failed your whitespace quiz :) | 16:53 |
| tedg | kgunn: Yes, you did :-) | 16:53 |
| ogra_ | heh | 16:54 |
| tedg | kgunn: Two spaces away from configflags. | 16:54 |
| ogra_ | and you thought python was insane, eh ? | 16:54 |
| tedg | Yeah, I find writing YAML so error prone. I really don't like it most of the time. | 16:55 |
| ogra_ | well, json isnt that much better | 16:55 |
| kgunn | tedg: 2 spaces away from configflags ? sorry...more context? | 16:55 |
| ogra_ | unless you have a properly highlightingv editor that shows the matching bracket .... and a gigantically big screen | 16:55 |
| tedg | kgunn: http://pastebin.ubuntu.com/12886920/ | 16:57 |

| jdstrand | Chipaca: hey, fyi, I had some time today to look at the click-apparmor removal. I decided to go with the go rewrite in the same pass since it occurred to my that cranking up the python interpreter twice (once for apparmor and once per seccomp) was going to really stink on arm | 21:20 |
| jdstrand | twice per app within the snap | 21:20 |
| jdstrand | that was not going to be nice | 21:21 |
| jdstrand | Chipaca: so, I have some code, nowhere near ready for merging, that actually generates apparmor and seccomp policy for security-template/caps and security-policy | 21:22 |
| jdstrand | Chipaca: but when I'm done, .click/ will be gone, the .json files will be gone, aa policy will move to /var/lib/snappy, and in general everything is going to be clean and nice | 21:24 |
| jdstrand | like how seccomp is now. but even that is going to be better cause we won't use sc-filtergen any more and the policy generation logic will have a clean internal api | 21:25 |
| Chipaca | jdstrand: yaaay! | 21:25 |
| jdstrand | so snappy install is cleaned up too | 21:25 |
| Chipaca | jdstrand: i needed this news :) | 21:25 |
| Chipaca | not because i was this desperate for click-apparmor removal | 21:25 |
| Chipaca | but because it's been a long, sucky day | 21:25 |
| Chipaca | and this is good :) | 21:25 |
| jdstrand | :( | 21:25 |
| jdstrand | glad I could give you some good news | 21:26 |
| jdstrand | it is going to take quite a bit of work for me to get everything in order, but I have a plan and even some code that is doing good things | 21:26 |
| jdstrand | so, hopefully in a couple weeks I'll have something to review | 21:27 |
| jdstrand | Chipaca: oh, and the weird security-override is going to be revamped | 21:28 |
| jdstrand | Chipaca: you won't specify a json file any more. you'll express the overrides directly in the package.yaml | 21:28 |
| jdstrand | eg: | 21:28 |
| Chipaca | jdstrand: that sounds nice | 21:28 |
| jdstrand | binaries: | 21:28 |
| jdstrand | foo: | 21:28 |
| jdstrand | security-override: | 21:28 |
| jdstrand | apparmor: | 21:29 |
| jdstrand | read-paths: [ /foo, /bar ] | 21:29 |
| jdstrand | that sort of thing | 21:29 |
| jdstrand | so it is all going to be nice and clean :) | 21:29 |
| Chipaca | excellent | 21:29 |
| jdstrand | security-override has been bugging me for a while | 21:30 |
