| [05:56] <mborzecki> morning | |
| [05:57] <zyga-mbp> hey mborzecki | |
| [05:57] <zyga-mbp> how are you doing? :) | |
| [05:57] <zyga-mbp> happy Thursday | |
| [06:08] <mborzecki> zyga-mbp: hey, yeah finally thursday, just one more day | |
| [06:09] <mardy> good morning mborzecki, zyga-mbp | |
| [06:10] <zyga-mbp> good morning mardy :) | |
| [06:11] <mborzecki> mardy: hey, i've pushed an update to https://github.com/snapcore/snapd/pull/10860 and it looks like i fixed the sync & buffer corruption in tests 🙂 there's still a little problem with that signal thingy being null sometimes, haven't really seen it on real dbus, so i'm guessing it's something about partial reads in the tests | |
| [06:11] <mup> PR #10860: sandbox/cgroup: wait for start transient unit job to finish <Created by bboozzoo> <https://github.com/snapcore/snapd/pull/10860> | |
| [06:12] <zyga-mbp> woah, nie | |
| [06:12] <zyga-mbp> *nice | |
| [06:22] <ares0128> Hi, i want to create an agent which manages the snap updates. to do that i would need to connect to snapd-control slot. But how do i use it? I read that it is using javascript file. But i have no idea how to use it. Could some one help me. | |
| [06:23] <zyga-mbp> ares0128 there's some logic that makes snapd go to managed mode and disable auto-updates | |
| [06:23] <zyga-mbp> then you have to call the snapd APIs to issue specific requests, like update that snap or all snaps | |
| [06:23] <zyga-mbp> whenever your software decides | |
| [06:23] <zyga-mbp> there's a bit of guard-rails around that feature, it's meant for core devices only | |
| [06:25] <ares0128> i tried following this https://github.com/dbruno74/node-red-node-snapd and https://github.com/madintec/snapd-control | |
| [06:25] <ares0128> but i dont know how to use these files | |
| [06:25] <ares0128> yeah i am making a snap for ubuntu core | |
| [06:25] <zyga-mbp> ares0128 that secodn thing is just a library, if you need javascript you can use it but that's not the point | |
| [06:26] <ares0128> how do i call snapd APIs | |
| [06:26] <zyga-mbp> snapd has a socket | |
| [06:26] <ares0128> it is through /run /snapd.socket | |
| [06:26] * zyga-mbp and a Go library to talk to it | |
| [06:26] * zyga-mbp the protocol is basically http over unix socket | |
| [06:26] * zyga-mbp the snap command actually talks to snapd over that socket | |
| [06:26] * zyga-mbp for snaps there's a second socket that lets snapctl talk to snapd | |
| [06:26] <ares0128> is there an example snap that i can refer to? | |
| [06:26] <zyga-mbp> snapctl is the thing that snaps can use internally to manage parts of themselves | |
| [06:27] <zyga-mbp> I don't recall but I'm sure there's something in the snapd test suite | |
| [06:29] <zyga-mbp> ares0128 https://github.com/snapcore/snapd/blob/master/tests/main/interfaces-snapd-control-with-manage/task.yaml#L71 | |
| [06:29] <zyga-mbp> ares0128 you get a snap with snapd-control | |
| [06:29] <zyga-mbp> you can set the snap set setting "system refresh.shedule" to "managed" | |
| [06:30] <zyga-mbp> and from there on you can just use snap to tell snapd to do things | |
| [06:30] <zyga-mbp> I think you can literally bundle the snap command as a quick test | |
| [06:31] <zyga-mbp> typically there are management agents implemented in whatever language | |
| [06:32] <zyga-mbp> they talk to snapd either through the go binary | |
| [06:32] <zyga-mbp> or through the C library | |
| [06:32] <zyga-mbp> or through the Go library | |
| [06:32] <zyga-mbp> there are official libraries to talk to snapd | |
| [06:32] <zyga-mbp> and perhaps several unofficial ones | |
| [06:32] <zyga-mbp> but the bulk of the idea is that you switch refreshes to managed and then you drive the refreshes yourself | |
| [06:33] <ares0128> so , i make a snap using go library that talks to snapd and chage the refresh to ,managed... | |
| [06:37] <mardy> mborzecki: the Read() and Write() method of the testDBusStream, can they be invoked on the same object from two different threads? | |
| [06:39] <mardy> (if so, you should protect that s.closed flag with a mutex) | |
| [06:52] <zyga-mbp> and back :) | |

| [08:44] <jamesh> oh. maybe I'm wrong. Let's see again | |
| [08:46] <pstolowski> jamesh: fwtw just using context.Background() makes no difference as far as close panic is concerned | |

| [08:53] <jamesh> pstolowski: I think this is a bug in godbus | |
| [08:53] <jamesh> and looks to still be a bug | |
| [08:54] <pstolowski> oh | |
| [08:54] <pstolowski> jamesh: as I said, maybe we could just not close() as a workaround | |
| [08:55] <pstolowski> slightly bad, but we are exiting anyway | |
| [08:55] <jamesh> If you call Conn.RemoveSignal(ch), then it is up to you to close the channel. If the D-Bus connection is closed, it closes all the signal channels | |
| [08:56] <jamesh> I'm not sure how you could write correct code with those semantics | |
| [08:58] <ogra> are there current known bugs with snap-device-helper ? i see a ton of errors on a pi4 (and how would i debug this ?) | |
| [09:00] <ogra> https://paste.ubuntu.com/p/Qwr6NkD3d7/ | |
| [09:00] <ogra> (seems all related to the opengl interface) | |
| [09:01] <ogra> (and i have to enforce SW rendering to make electron run (or use devmode)) | |
| [09:21] <jamesh> pstolowski: I filed https://github.com/godbus/dbus/issues/271 about the problem | |
| [09:21] <jamesh> pstolowski: in the short term, leaving the channel unclosed with a comment pointing at that bug report is probably the best option | |
| [09:22] <pstolowski> jamesh: awesome, thanks for digging into it and providing good explanation in the bug report! | |
| [09:28] <zyga-mbp> jamesh nice one | |
| [09:29] <jamesh> zyga-mbp: it'd be even nicer if I could think of a fix that wouldn't break compatibility... | |
| [09:29] * zyga-mbp jamesh I'm actually using that library as well; I'm in a bit of crunch mode before my release (6 weeks left) but I will think | |
| [09:30] <jamesh> zyga-mbp: the best I can think of is to have a second version of RemoveSignal that closes the connection | |
| [09:35] <zyga-mbp> jamesh would it be possible to use WIthSignalHandler and provide a different logic for AddSignal and RemoveSignal? | |
| [09:35] <zyga-mbp> those seem to be dispatched with an interface | |
| [09:36] <zyga-mbp> and ther's a way to set the signal handler per connection instance | |
| [09:39] <jamesh> they abstracted a lot of things in godbus that they probably shouldn't have (e.g. serial number generation) | |
| [09:39] <jamesh> but replacing the default implementation with one that implements different semantics seems like a bad idea | |
| [09:45] <zyga-mbp> jamesh I wonder if upstream reacts quickly or not | |
| [09:46] <zyga-mbp> there seems to be little traction | |
| [09:47] <jamesh> zyga-mbp: they've accepted pull requests from me, and I've helped review others. I think it is more a case of lack of time. | |
| [09:47] <zyga-mbp> that's good then | |
| [09:48] <jamesh> e.g. fixing the race conditions that used to exist in RemoveSignal | |

| [09:53] <pstolowski> jamesh: i'm also now occasionally seeing [signal SIGSEGV: segmentation violation code=0x1 addr=0x28 pc=0x7ad006] on github.com/snapcore/snapd/desktop/notification.(*fdoBackend).processSignal(0xc0000c2820, 0x0, 0x0, 0x0, 0x0, 0x0) now in this code (after avoiding close), still a race somewhere | |
| [09:54] <pstolowski> but maybe it's related to the new test i'm adding in usesession/agent | |
| [09:58] <jamesh> pstolowski: I'm not sure. I didn't see any segfaults after removing the close() from what you'd posted earlier | |
| [09:58] <jamesh> did it give you any more information than that? | |
| [09:59] <pstolowski> jamesh: no, let's not worry about that right now, i may know more when I finish my test, may as well be a problem with my test code | |
