vrurg 2019.03 doesn't build on macOS with MacPorts. 00:30
Ok, found it's moar, found the README. Bailing out because of "wong" make?? Seriously??? 00:41
vrurg is furios
s/wong/wrong/ 00:48
timotimo vrurg, you mean ports vs xcode? 00:51
perhaps the detection of that pathological situation is a bit too sensitive 00:52
but bailing out early is much preferable to getting the other failure mode
vrurg aha. MacPorts installs gnu make as a dependency. This is normal. XCode uses GNU make too. What was the point of checking for make in Configure.pl?
timotimo which is a message that is just wrong and completely misleading
vrurg I'm thinking to patch it. Maybe with a hack to use /usr/bin/make if cc is found in that location. 00:54
timotimo github.com/MoarVM/MoarVM/pull/1055
check the pr
vrurg And anyway I totally agree to the need of validating ar/ld/cc for consistency.
timotimo: thank! I found the commit, it's self-explanatory. 00:55
timotimo ok, if checking make doesn't make sense, a patch would be welcome, perhaps even a short comment I. the file 00:56
for now I will go to bed and may not be able to do anything all day tomorrow
if I'm not reacting to your patch, it's not you, it's me ;)
vrurg timotimo: no problem. Thanks! :) 00:57
AlexDaniel vrurg: um, sorry, so is it a new issue? 01:42
or was it just a problem with your setup?
AlexDaniel is confused
vrurg AlexDaniel: it's a new one. Arises from a good intention to prevent a mixture of XCode and gnu tools. 01:43
AlexDaniel hmm
vrurg timotimo pointed to the pull request which introduced it. I'm trying to figure out a better way to achieve the goal.
Basically, it's either about ignoring make which from another toolchain or about enforcing the right one. 01:44
Though I would probably combine both and make rakudo and moar rely on /usr/bin/make if /usr/bin/cc or clang is used. 01:45

so on all releases since 2015.12 the result is the same
Geth Ā¦ rakudo: AlexDaniel self-unassigned Issues with contributors generating script github.com/rakudo/rakudo/issues/2028 08:43
gfldex I got a script that can segfault moarvm quite fast. Needs linux and iostat. If a single line is commented out, it runs the whole night without a segfault: raw.githubusercontent.com/gfldex/b.../iostat.p6 09:08
Also it's quite resistent to golfing (or I would have). 09:09
AlexDaniel gfldex: so I'm running that in a loop and nothing is happening, what am I doing wrong? 09:24
gfldex AlexDaniel: ohh, please start it with 1 a parameter 09:28
it tends to segfault after 4-8 secs for me. Sometimes it takes a little longer.
I golfed it a little more. Update is on github. 09:33
AlexDaniel yeah, I see a segfault 09:58
gfldex: it'd help if you manage to include JSON::Stream in that golfed file
gfldex AlexDaniel: That module is not mine and fairly big. I should be able to simulate it and get rid of shelling out altogether. 10:04
10:04 pmurias joined
AlexDaniel gfldex: yeah but once it is all in the same script we'll have an actual golf 10:04
and we'll be able to throw that into committable 10:05
wellā€¦ we can also make it work with a module, too 10:06
I'm just not in the mood :D
pmurias MasterDuke: I don't have a direct solution, an obvious solution would be figure out what that type is 10:07
yoleaux 04:11Z <MasterDuke> pmurias: i'm trying to get the jvm backing working with my default-nqp-to-int branch, but am getting an error i'm not familiar with. i've got some backtrace from before any code change, backtrace from after code change, and the change diff here gist.github.com/MasterDuke17/b69bf...473842af1. any suggestions?
gfldex AlexDaniel: No luck. When I take the module out the segfault goes away. 10:25

Congratulations all around! Great to have a release again.
I don't have much time in the coming week for post merge fixups, but I'd like to get my relocatable branches merged soon after, given there is are no other objections to the merge. 15:51

Kaiepi has 2019.03 been released yet? 18:20
robertle yes: github.com/rakudo/rakudo/releases 18:27
Kaiepi perfect
can someone review github.com/rakudo/rakudo/pull/2478 and the related pullreqs?
AlexDaniel robertle: the signature is going to change for the next release 18:28

robertle what do you mean with "signature"? I don't understand... 18:31

cfa this seems lta; encountered during a refactor
i think the panic's been there or a long time

bisectable6 cfa, Bisecting by output (old=2015.12 new=70d61b2) because on both starting points the exit code is 1
robertle AlexDaniel: hm, but if noone signed the original tarball on github, where we get it from?

camelia An operation first awaited:

Died with the exception:
Attempt to return outside of any Routine
in block at <tmp> line 1
AlexDaniel robertle: so you can also check it in git by looking at the tagged commit
actually, the tag itself is also signed!
everything is signed. Everything! 18:48

committable6 AlexDaniel, gist.github.com/99ac72bb06c33274df...b56117bbd3 18:49
AlexDaniel cfa: wow, this is really simple, but I haven't seen a bug report for that! Yeah, the code of course doesn't make much sense, but MoarVM panic is not the right answer :) 18:50
cfa right
i mean, the toplevel versoin gives a reasonable error
my refactor was closer to the first golf
where a return ended up inside an await start { }
version* 18:51
robertle right, I was confused. we do get the files from rakudo.perl6.org/downloads/rakudo/ where they do have signatures. who will be doing the releases in the future?
AlexDaniel actually, I don't understand why the top level version works but the same thing in a sub doesn't
cfa me neither!
but the error makes sense 18:52
the panic does not (from a user perspective ofc)
AlexDaniel robertle: there's a volunteer but it's not official yet
robertle awesome! viele haende schnelles ende 18:54
AlexDaniel cfa: soo, file a bug report? :) 19:02
cfa yep 19:10

MasterDuke there's a small chance i could go to either the swiss perl workshop or the europe perlcon. any recommendation for one over the other? 22:05
timotimo i know i will not be at riga, i don't know if i will make it to SPW 22:10
OTOH, riga has the potential to draw a much bigger crowd in general
MasterDuke any thought on the locations (non-conf stuff to see/do)? 22:11
timotimo somehow managed a segfault in readint 22:13
no thoughts
