| robin-hero_ | Hey all, I bought a SlimPort-HDMI adapter last week, but I can't charge my phone and connect it to an external display at the same time: I've already filled a bug: https://bugs.launchpad.net/ubuntu/+source/mir/+bug/1519235 | 08:31 |

| robin-hero_ | If I remember correctly, it works with Android, but not with Ubuntu | 08:32 |

| anpok_ | hm it works for me | 08:58 |
| anpok_ | robin-hero_: the one I use looks more like this one http://www.amazon.com/Yakamoz-Slimport-Adapter-Cable-Lovely/dp/B00H8QIUZG/ref=sr_1_81?ie=UTF8&qid=1449046804&sr=8-81&keywords=slimport | 09:00 |

| white_duck | wohoo mir 0.19 | 09:33 |
| robin-hero_ | anpok_, Hmm, I need to relfash Android to test again, If it wouldn't work well with that it it a hardware problem with the adapter. | 09:33 |

| alan_g | AlbertA: thanks for picking up the ubsanitizer work, I've been meaning to get around to that but getting distracted..since April :( | 17:18 |
| AlbertA | alan_g: no problem, I didn't even know it existed until you mentioned it yesterday :) | 17:21 |
| AlbertA | alan_g: no other major reports other that those two bugs I have MPs for... the rest are issues with gmock or a gcc ubsan bug complaining about non-capture lambdas | 17:22 |
| alan_g | If you'd been at the ACCU conference last year you couldn't have missed it. ;) | 17:23 |
| alan_g | Well, the last conference (which was this year) | 17:23 |
| alan_g | @"issues with gmock" - surprising, I know google are big users of ubsan | 17:25 |
| AlbertA | alan_g: apparently fixed in their trunk: https://groups.google.com/forum/#!msg/googlemock/cHSPZfcIwSc/sYAzFl2DCQAJ | 17:31 |
| AlbertA | I get various reports of "/usr/include/gmock/gmock-spec-builders.h:1530:60: runtime error: member call on null pointer of type 'const struct ResultHolder'" | 17:31 |
| alan_g | AlbertA: I guess we're too late to get an update in vivid. :( | 17:32 |
| alan_g | *into | 17:32 |
| alan_g | AlbertA: just checking, your bug 1522105 isn't a different manifestation of bug 1514884 is it? (Fix landed recently.) | 17:37 |
| ubot5` | bug 1522105 in Mir "NestedServer.display_configuration_reset_when_application_exits segfaults" [Medium,New] https://launchpad.net/bugs/1522105 | 17:37 |
| ubot5` | bug 1514884 in Mir "There's something racy in NestedServer.display_orientation_changes_are_forwarded_to_host" [Medium,Fix committed] https://launchpad.net/bugs/1514884 | 17:37 |
| AlbertA | alan_g: probably a different cause now... I tried the tip of lp:mir | 17:38 |
| alan_g | OK, just sounded possible as it could have been an affected case. | 17:39 |
| AlbertA | alan_g: looks like surface stack is sending a null surface pointer to the observers | 17:40 |
| AlbertA | based on the GDB backtrace | 17:40 |
| alan_g | I see. If you don't get to it I'll have a look in the morning. | 17:41 |
| AlbertA | oh yeah.. SurfaceStack::add_observer drops/reacquires the lock as it loops over the existing surfaces...so that needs fixing | 17:45 |
| alan_g | Oh, that looks painful. | 17:51 |
| AlbertA | alan_g: yep... the good ol' callback problem... | 17:54 |
| * alan_g decided to end the day before getting too interested in solving that one. | 17:55 | |
| === alan_g is now known as alan_g|EOD | ||
| alan_g|EOD | (it doesn't work) | 17:57 |
| alan_g|EOD | AlbertA: could it be as simple as copying "surfaces" under lock and looping over the copy? | 18:00 |
| * alan_g|EOD => really EOD | 18:01 | |
| AlbertA | alan_g|EOD: it could but then the observer calls could be out of order: like receiving surface_removed before surface_exists | 18:01 |
| AlbertA | which would be odd | 18:02 |

| Saviq | kgunn, tracked down to line 95 in http://bazaar.launchpad.net/~mir-team/qtmir/trunk/view/head:/src/platforms/mirserver/surfaceobserver.cpp#L95 | 22:23 |
| Saviq | meaning we're getting a nullptr as cursor, and not expecting it | 22:23 |
| Saviq | folks, should SurfaceObserver::cursor_image_set_to deal with null pointers? is it expected that we're getting it? see bug #1522117 | 22:25 |
| ubot5 | bug 1522117 in qtmir (Ubuntu) "Unity 8 desktop session "stops" when exiting an X app" [Critical,Triaged] https://launchpad.net/bugs/1522117 | 22:25 |
| kgunn | anpok: ^ | 22:27 |
| shiznix | is Wily Mesa supposed to build with Wily Mir, or is this a WIP? | 22:34 |
| anpok | Saviq: not expected.. i thought AlbertA working on something similar, but looking through the logs he was after something different | 22:38 |
| Saviq | oh so we actually uncovered a mir bug? | 22:38 |
| AlbertA | Saviq: maybe it's this? https://code.launchpad.net/~albaguirre/mir/fix-1521795/+merge/279218 | 22:39 |
| Saviq | AlbertA, definitely sounds related | 22:40 |
| shiznix | encountered pkgconfig problem where mesa-11.0.2-1ubuntu4 can't find 'mir-client-platform-mesa-dev' as this was renamed to 'mir-client-platform-mesa' in mir-0.17.0+15.10.20151008.2-0ubuntu1 | 22:43 |
| shiznix | but once this small typo is smoothed over, mesa fails to build -> http://webcache.googleusercontent.com/search?q=cache:jmRbpw2aKBQJ:pastebin.com/G7pLiWRT+&cd=2&hl=en&ct=clnk&gl=au&client=ubuntu | 22:44 |
| shiznix | not my pastebin, but exactly the same build error | 22:45 |
| shiznix | and somewhat reassuring that i'm not the only one :D | 22:45 |
| shiznix | apologies for the noise if they're not intended to build together yet | 22:46 |
| RAOF | shiznix: They are expected to build together; which versions are you building, though? | 23:01 |
| RAOF | Ah, mesa 11.0.2 vs mir 0.17? | 23:01 |
| shiznix | RAOF: yes :) | 23:54 |
