| ilmari | nwc10: that's probably my fault | 11:27 | |
| ilmari has a look | |||
| i >= result_alloc - repl_length # fails when repl_length > result_alloc | 11:34 | ||
| all the variables are unsigned | |||
| MVMuint32 or size_t | |||
| nwc10 | I'm not familiar with that code, so can't comment | 11:35 | |
| and a bit too much $work is happening currently | |||
| timotimo | well, looks like ilmari is about to fix it | 11:36 | |
| ilmari | how us(able|eful) is ASAN on gcc 4.9.2 (debian)? | ||
| timotimo | i think it's usable | 11:37 | |
| you'll need to install that extra package, but it'll be fine | |||
| and we have the helpful --asan thing for Configure.pl | 11:38 | ||
| ilmari | yeah, I found that | ||
| timotimo | good good | ||
| nwc10 | ilmari: the question is ASAN on that debian generally? Or ASAN for MoarVM? | 11:45 | |
| ilmari | nwc10: in general | 11:46 | |
| nwc10: I was just wondering if I should install a newer gcc or clang, or whether I can just build with --asan on stock debian stable | 11:47 | ||
| nwc10 | OK, I don't know. | ||
| timotimo | actually, i wonder if we should enable ASAN on our travis builds? | ||
| especially since we're usually ASAN clean | |||
| arnsholt | Using the stock compiler should be OK for ASAN and such | 11:48 | |
| nwc10 | ilmari: the ASAN I'm using is gcc (GCC) 4.9.0 | 11:52 | |
| a local build on CentOS $something | 11:53 | ||
| (it's "my" machine, not my machine) | |||
| we get some hangs on ASAN builds in the tests for various concurrency features | |||
| timotimo | oh, damn | ||
| nwc10 | I assume that these are race conditions we hit due to slower execution times | ||
| but they'd really hurt on an automated build | 11:54 | ||
| and however much we go | |||
| jnthn++ | |||
| there still only seems to be one of him | |||
| and I think he's got other things to look at first | |||
| timotimo | that's fair | 11:55 | |
| jnthn | People who can debug concurrency bugs seem to be few and far between | 11:57 | |
| nwc10 | good UGT, jnthn | 11:59 | |
| jnthn | o/ | ||
| nwc10 | there's a lot of contention on the time of the folks who can debug concrrency bugs | ||
| timotimo | %) | ||
| jnthn | And, sadly, debugging concurrency bugs seems to need to acquire a mutex on their brane | 12:00 | |

| konobi | how does the build/setup.pm work? (in terms of OS vs Platform vs toolchain) | 12:55 | |

| ilmari | nwc10: I have a fix for the overflow in ascii (and latin1, windows1252 and utf8(_c8)), but utf16 is still borked | 14:16 | |
| because it does no checking at all, just assumes that any charcter can fit in 4 bytes | |||

| timotimo | ilmari: will we get that as a pull request or patch? :) | 20:25 | |
| jnthn suspects PR | 20:30 | ||
| I think ilmari is hacking at lunchtimes though, so we'll likely have to wait until lunchtime happens again ;) | |||
| nwc10 | and being ilmari, we might have to wait several days until he remembers that it's lunchtime | 20:31 | |
| [Coke] | crap, lunch. | 20:33 | |
| nwc10 | oh no, not *another* ilmari | 20:34 | |
| ilmari | nwc10: accept no imitations! | 20:39 | |
| psch | hm, an arg with a non-MVM_CALLSITE_ARG_OBJ arg_type doesn't have a container spec, right? | ||
| ilmari | jnthn: my home laptop has started having thermal issues, so I prefer anything that involves lots of compiling on my work workstation | 20:40 | |
| timotimo | accept no limitations! | ||
| psch | or is that just not reachable with .o but instead the corresponding typed... something (register?) | ||
| [Coke] | I'm not actually hungry, despite it being nearly 4pm here. weird. | 20:44 | |
| nwc10 | I "just" outsource my compiling to shell accounts other people give me | 20:45 | |
| jnthn | psch: Um...I think it's unreachable *at the moment* | 20:46 | |
| Not sure it should be | |||
| psch | jnthn: because that's what it looks like is missing | 20:48 | |
| as in, cached dispatch between Int and Int is rw works | 20:49 | ||
| but bring an int is rw and int in there it only dispatches the the latter | |||
| jnthn | Oops. :) | 20:51 | |
| jnthn wonders if the cahce needs to learn about native refs... | |||
| psch | gist.github.com/peschwa/92605dd3ec50054f9a9d is my test case, just to make sure i'm not messing that up again... :) | 20:56 | |
| jnthn | psch: Need to rest now; will look in the monring :) | 21:14 | |
| konobi | afternoon all | 21:26 | |
