| barry | pitti: love the new summary at the end of adt-run | 15:13 |
| pitti | barry: me too! nice idea | 15:13 |
| pitti | barry: one of these 5 s improvements :) | 15:14 |
| barry | pitti: :) | 15:14 |
| slangasek | tdaitx: "unable to change status" - so we need to get you bug privileges still? | 15:15 |
| tdaitx | slangasek, possibly, I was not sure if I should have them already or just after I got in as a core dev | 15:17 |
| slangasek | tdaitx: there's a separate process for getting bug triaging privileges that doesn't require you to be an Ubuntu dev; bdmurray probably has the link handy :) | 15:18 |
| infinity | I don't see why that MIR would need its status changed? | 15:18 |
| slangasek | tdaitx: though for MIR bugs, note that the bug is a process bug so you probably don't need to change its state anyway, the MIR team does this | 15:18 |
| bdmurray | tdaitx: https://wiki.ubuntu.com/UbuntuBugControl | 15:19 |
| bdmurray | "Requirement 4 can be waived if you are an upstream developer or bug triager or if a Ubuntu developer vouches for you (your triaging ability)." | 15:19 |
| slangasek | any other questions over status? | 15:19 |
| slangasek | [TOPIC] AOB | 15:21 |
| === meetingology changed the topic of #ubuntu-meeting to: AOB | ||
| slangasek | pitti, bdmurray: there's a bug escalated by the phone team about apport that I'd like to get your input on | 15:21 |
| slangasek | bug #1278780 | 15:21 |
| ubottu | bug 1278780 in apport (Ubuntu) "apport takes too long to write crash report, appears to lock up phone" [High,Triaged] https://launchpad.net/bugs/1278780 | 15:21 |
| pitti | slangasek: I've seen it; you summarized it well | 15:21 |
| slangasek | ok | 15:21 |
| pitti | apart from the nice level tweakage I'm afraid I don't have any othe magic sauce to pour over this, though | 15:22 |
| infinity | tdaitx: For MIRs of this nature specifically, if something has been in main in the past and fell out again (because it was unseeded or nothing depended on it anymore), just poke an archive admin with a pointer to the old bug/status, and we can re-promote it (done now). | 15:22 |
| slangasek | I think the short term plan is that crash reporting will be disabled on the phone by default until they can give us something more fine-grained for blacklisting | 15:22 |
| pitti | high nice level is better for background processes and worse for foreground, so maybe we should optimize for the latter | 15:22 |
| pitti | slangasek: but TBH I doubt that it'll make a noticeable difference | 15:23 |
| pitti | it might suck a tad less, but it'd still suck | 15:23 |
| slangasek | pitti: would you be ok with dropping the os.nice() call anyway, to see if it does make a difference? | 15:23 |
| pitti | slangasek: yes, I'm fine with that; I'd just not claim that this would fix the bug | 15:23 |
| doko | tdaitx, no need to redo the MIR, it already was approved. promoted that | 15:23 |
| slangasek | and am I right that when the unity system compositor is what crashes, the kernel has to dump all the mapped memory, including the graphics buffers? | 15:23 |
| tdaitx | bdmurray, slangasek yeah, I have that page saved, I am in the bug squad and was collecting additional triaging experience before I sent out my request to join bug control | 15:24 |
| bdmurray | Disabling by default seems a bit drastic to me. Given pitti's changes to apport, which has resulted in more crashes being reported, have there actually been more reports complaints re "appears to lock up phone" | 15:24 |
| pitti | slangasek: I'm less sure about that (not famiilar with the innards of core dumps), but it seems likely | 15:24 |
| slangasek | bdmurray: yes, there have | 15:24 |
| slangasek | bdmurray: and it's a grave issue, including potentially a regulatory one if the phone is blocked and you can't make an emergency call | 15:25 |
| barry | on a different note, is anybody here a libunity expert (or know one)? | 15:25 |
| bdmurray | slangasek: alrighty | 15:25 |
| infinity | slangasek: That would certainly have been true in the old skool Xorg days with an mmapped /dev/mem, can't say how unity8/mir behave in that regard, but it seems likely. | 15:25 |
| slangasek | bdmurray: I'm going to continue pressing the phone team for a fine-grained blacklist so that we can do something better than disabling it by default, but I don't think we should block on this | 15:26 |
| bdmurray | it looks like Laney has been working on the ability to turn on and off crash reporting | 15:26 |
| slangasek | infinity, pitti: what if the system compositor had a custom SIGSEGV handler to unmap the video buffers and reraise the signal? | 15:26 |
| slangasek | bdmurray: there's a toggle for it in the UI that apparently doesn't work right currently | 15:27 |
| pitti | slangasek: that would certainly be very helpful | 15:27 |
| slangasek | pitti: "helpful" - but would it be sane? :) | 15:27 |
| infinity | "maybe". | 15:27 |
| bdmurray | slangasek: right, he's made some changes to whoopsie-preferences today see bug 1437633 | 15:27 |
| ubottu | bug 1437633 in Canonical System Image "Choosing not to report crashes and errors setting reverts" [Critical,In progress] https://launchpad.net/bugs/1437633 | 15:27 |
| pitti | slangasek: for most processes it shouldn't take that long, supposedly not manyu programs are handling huge gfx buffers | 15:27 |
| infinity | Manipulating memory after a crash is always iffy. | 15:27 |
| pitti | slangasek: absolutely, yes | 15:27 |
| infinity | We have such features intentionally disabled in glibc because it's pretty lolz to operate on pointers that might be pointing to another universe. | 15:28 |
| pitti | slangasek: it's dramatically unlikely that a stack trace goes "through" the framebuffer, there should be no code there | 15:28 |
| pitti | slangasek: and in the end the stack trace is all that we keep anyway for a successful retrace | 15:28 |
| slangasek | bdmurray: right, that's the other bug that pmcgowan mentioned | 15:28 |
| pitti | slangasek: so freeing data can only be helpful | 15:28 |
| slangasek | pitti, bdmurray: so it seems at least worth suggesting this to the unity team | 15:28 |
| infinity | pitti: If the crash is in shader magic or something, it could absolutely be running rampant through video memory. | 15:28 |
| slangasek | infinity: would that show on the process stack? | 15:29 |
| pitti | infinity: well, we can't dump GPU code anyway, can we/ | 15:29 |
| pitti | ? | 15:29 |
| infinity | slangasek: Hrm. Probably not, I suppose. Would just be an opaque call from libgl. Probably. | 15:29 |
| infinity | I'm a bit rusty on all of that, it's been a decade since I lived with daniels. | 15:29 |
| pitti | I mean, if we have the choice between "no bugs for unity" vs. "a few corner cases have broken stack traces", the former sounds much more desirable | 15:29 |
| pitti | err, the latter | 15:29 |
| slangasek | ok, I'll suggest this then, thanks | 15:29 |
| pitti | (not that unity having no bugs wouldn't be desirable..) | 15:30 |
| slangasek | (I'm not sure how much of the process's memory will actually be video buffers, but it's worth looking at) | 15:30 |
| pitti | slangasek: are you aware of the "gcore" tool? | 15:30 |
| slangasek | no | 15:30 |
| infinity | pitti: We can dump GPU code, but it would be an entirely different trace, via a callback to the kms driver or libgl. | 15:30 |
| pitti | slangasek: quite handy for doing such comparisons without acutally having to crash your program | 15:30 |
| infinity | pitti: See all the Intel GPU vomit one gets in dmesg. :P | 15:30 |
| slangasek | pitti: ah nice | 15:31 |
| pitti | infinity: right, I thought X (or kernel or whatever) has some special apport hooks for that | 15:31 |
| infinity | pitti: X does, yes. | 15:31 |
| pitti | slangasek: so one could do gcore / do something to trigger video memory free / gcore again / compare | 15:31 |
| infinity | pitti: Mir probably wants the same ones. | 15:31 |
| slangasek | pitti: pmap might also give us the info we need for this | 15:31 |
| slangasek | infinity: if the phone were using KMS, sure ;) | 15:32 |
| slangasek | (yes eventually we want it for the desktop if we don't have it there already) | 15:32 |
| bdmurray | its probably worth noting that fixing bug 1437633 won't actually stop apport from creating crash reports | 15:32 |
| ubottu | bug 1437633 in Canonical System Image "Choosing not to report crashes and errors setting reverts" [Critical,In progress] https://launchpad.net/bugs/1437633 | 15:32 |

| slangasek | bdmurray: thanks for catching that | 15:33 |
| bdmurray | bug 1389407 might be better | 15:33 |
| slangasek | so really we're looking at an upstart override or something here | 15:33 |
