ShimmerFairy I can't seem to figure out a universal name of getting the name of a type in NQP (trying to write a quick little dumper). The consternation seems to be with the BOOT types, but simple examples work fine. 09:01

MasterDuke patrickb: any idea why e.g., github.com/MoarVM/MoarVM/pull/1312 has its top three azure jobs failing? seems like those particular ones are failing across a bunch of different commits/prs 09:24

MasterDuke ShimmerFairy: does ^^^ help?
ShimmerFairy That's one of those simple examples that works, but $obj.HOW.name($obj) in practice falls apart (this is dealing with the output from instrumented profiling, btw). 09:35
I wish I could generate a minimal (non)working example, but it's kinda hard to know what about the object makes it fall apart when all you can know about it is its REPR. 09:36
For the record, it's some kind of VMArray that's breaking things. 09:37
MasterDuke hm, then i'd suggest pinging timotimo 09:39

should we trust Timotimo's cats who claimed that github.com/MoarVM/MoarVM/pull/1311 should be changed :-) 14:18

MasterDuke i suspect this is one of those cases where in all likelihood it'd be fine in practice, but in theory there's a chance for error 14:22

timotimo ShimmerFairy:at the moment profile data from threads that have been removed again (which i assume threadjoin will do) will be discarded in the instrumented profiler 15:08
ShimmerFairy: have you tried the debugname ops? nqp::getdebugname perhaps
ShimmerFairy Haven't heard of the debugname ops, would probably help. (And btw, using threads even with threadjoin did seem to keep data, it's how I found out how multiple threads' hashes are put in the return of mvmendprofile) 15:10
timotimo good to know, i thought i'd for sure have to put something in there to hold on to thread's data after they die 15:11

timotimo hum?
ShimmerFairy they don't exist, turns out 15:12
timotimo aha 15:13
there is only setdebugtypename in moar's interpreter
i suppose it really is only for giving a c string name to moarvm's internals for easier / cheaper debug outputting in error messages and such? 15:14
they are probably set everywhere we're also setting a name in the metaobject though? 15:15
ShimmerFairy The one time I managed to create an error message giving some kind of name was from an error generated in MoarVM that directly looks into the STable. 15:16
timotimo debugtypenames are also used in the spesh log for example 15:18

timotimo 691:#define IS_CONCRETE(o) (!(((MVMObject *)o)->header.flags & MVM_CF_TYPE_OBJECT))
looks like we do want a null check in front of IS_CONCRETE if something can be null 15:19
ShimmerFairy AFAIK nqp::isconcrete() (at least currently) is meant to be just "is it NOT a type object?", which a null counts as not being. 15:21
I don't know if that macro maps directly to the opcode, though.
timotimo i think we mostly use isconcrete when we want to access something's attributes and such, which we can't do for type objects and can't do for null, so that's my intuition 15:23
indeed, the isconcrete opcode is implemented as a null check + IS_CONCRETE
ShimmerFairy I guess "is a null a type object" is a question that borders on the philosophical, could go either way :P 15:24
btw, I was surprised to find that nqp::isnull_s($x) stringifies its argument. Not necessarily wrong, just didn't expect it. 15:26
timotimo we did put in a type explicitly to mimic a null but not a null pointer 15:27
ah, yes, that really is slightly odd; i guess you're expected to only use it on str registers in the first place? i.e. after a decont_s or some such? 15:29
and if the register you're using it on is num, int, or obj, the qast compiler will helpfully place a coercion for you 15:30
ShimmerFairy In the script I posted, I tried a nqp::isnull_s check right after the isnull check to print a special "null string" thing. I could've easily put a nqp::isstr($obj) in front to avoid the coercion issue, but it wasn't that important. 15:31
timotimo did you steal anything from the built-in profiler dumper? 15:35
ShimmerFairy there's a built-in profiler dumper? 15:39
timotimo it dumps to html / json / sql 15:43
so maybe "dumper" isn't the right word for it?
ShimmerFairy tbf my little script is probably more of a pretty printer (or, a Raku dumper I guess) 15:44
timotimo there ought to be a way to get the default dumper from regular user code 15:45
Telemetry, which comes with rakudo, already offers a heap snapshot function
but that's easier since moarvm does all the file output parts there
