pmurias | hmm, I'm working on hooking up loading (precompiled and to be precompiled) modules to parcel and I'm not sure what would be a good model to hook it up to CompUnit::* stuff | 09:09 | |||||||||||||||||||||||||||||||||||||
what I think I want to do is to take a p6 script with some use statements and get back a bunch of compiled code | 09:11 | ||||||||||||||||||||||||||||||||||||||
nine | What's parcel? | ||||||||||||||||||||||||||||||||||||||
pmurias | a js module bundler | ||||||||||||||||||||||||||||||||||||||
parceljs.org/ | 09:12 | ||||||||||||||||||||||||||||||||||||||
nine: it takes a bunch of assets (files which are treated differently depending on extensions) and then builds a single .js file + .css + whatever you hook into it | 09:13 | ||||||||||||||||||||||||||||||||||||||
nine | Sounds like the job for a new CompUnit::Repository implementation accompanied by an alternative to CompUnit::PrecompilationStore::File | ||||||||||||||||||||||||||||||||||||||
pmurias | so the new CompUnit::Reposity would record stuff that's being found in other repositories? | 09:19 | |||||||||||||||||||||||||||||||||||||
nine: or did you mean for teaching Rakudo to be able to load stuff from parcel? | 09:21 | ||||||||||||||||||||||||||||||||||||||
nine | Both. An in-memory CompUnit::PrecompilationStore is easy to implement and saves you from having to find the generated precomp files. It will also help with loading precomped code from however parcel manages files. | 09:26 | |||||||||||||||||||||||||||||||||||||

We're 11 days from 6.d release, so it's cutting it kinda close, with 6.e we get more time to play with it to see if it's a good idea.

For :D's to be accepting :U's it makes as little sence as an Int:D constraint accepting an `Int` This is part of fixing github.com/rakudo/rakudo/issues/2073 A more complete fix might involve banning the use of Enum:D's in the same place as other types and instead requiring the use of `where` clauses for such use. |

It seems like we're somehow getting duplicate type objects | |||||||||||||||||||||||||||||||||||||||
o.O | 17:03 | ||||||||||||||||||||||||||||||||||||||
timotimo | some kind of repossession issue? | ||||||||||||||||||||||||||||||||||||||
shouldn't be, since nothing is modifying the original type objects | |||||||||||||||||||||||||||||||||||||||
hum. | |||||||||||||||||||||||||||||||||||||||
jnthn | No, I don't think it's that | ||||||||||||||||||||||||||||||||||||||
There is repossession happening because of that set_name but commenting that out changes nothing. | 17:04 | ||||||||||||||||||||||||||||||||||||||
(and I verified there's no repossession going on) | |||||||||||||||||||||||||||||||||||||||

stmuk_ | whats actually happening with 6.d (I'm out of touch)? will .10 still have 6.d-preview and .11 6.d? | 17:26 | |||||||||||||||||||||||||||||||||||||
timotimo | phew. | ||||||||||||||||||||||||||||||||||||||
Zoffix | stmuk_: I don't think we can just break `use v6.d.PREVIEW` willi-nilli, because there are modules using it (at least one of mine does) and also module authors would want to support at least a couple of recent Rakudo versions, so my thinking is `use v6.d.PREVIEW` on .11 will be equivalent to `use v6.d` which will be equivalent to no `use` at all and `use v6.c` will load 6.c language. Whereas on .10, no | 17:28 | |||||||||||||||||||||||||||||||||||||
`use` loads `v6.c` and `use v6.d` is a compiler error | |||||||||||||||||||||||||||||||||||||||

tbrowder___ | rakudo nqp question, please: i notice sometimes dynamic vars values are assigned lika a regular var, and other times the var is assigned via the nqp::*lex* ops. is that a holdover from the early days, or is it something that should be āconsistifyedā, or is it imporatant in some way i donāt yet understand? thanks! | 21:06 | |||||||||||||||||||||||||||||||||||||
lizmat would like to see an answer to that one as well :-) jnthn timotimo ? | 21:09 | ||||||||||||||||||||||||||||||||||||||
timotimo | assigned to or accessed? | 21:11 | |||||||||||||||||||||||||||||||||||||
lizmat | assigned, apparently | ||||||||||||||||||||||||||||||||||||||
"other times the var is assigned via the nqp::*lex* ops" | 21:12 | ||||||||||||||||||||||||||||||||||||||
timotimo | i'd probably need to look at some examples to figure that out | ||||||||||||||||||||||||||||||||||||||

tbrowder___ | i notice many (if not all) the cases with regular assignment use :my $*var inside the calling block, so maybe that establishes the calling place so the lexdyne method is not necessary. | 21:33 | |||||||||||||||||||||||||||||||||||||
timotimo | we often have to do some gymnastics so that we refer not to the just-defined dynamic variable, but to whatever came before it | ||||||||||||||||||||||||||||||||||||||
not sure if that's what you're looking at | 21:34 | ||||||||||||||||||||||||||||||||||||||
tbrowder___ | eel | ||||||||||||||||||||||||||||||||||||||
*well, iām all over the place but zeoring in...the vars iām interested in are defined in the grammar and affect pod block handling, and most places (but i canāt say all) have the :my construct in the block that wants to change the value during complete contruction of the class associated with the block. and the code child path goes back and forth between grammar, actions, and pod. | 21:38 | ||||||||||||||||||||||||||||||||||||||
i may need that ājust beforeā value before i finish... | 21:39 | ||||||||||||||||||||||||||||||||||||||
samcv | we shouldn't be using hardly any cpu during a `prompt` right? | 21:41 | |||||||||||||||||||||||||||||||||||||
timotimo | yeah | 21:42 | |||||||||||||||||||||||||||||||||||||
hopefully we can wait for input without polling | |||||||||||||||||||||||||||||||||||||||
there are cases where we get incredible cpu load when doing nothing, like when our process is piped to a pager :( | 21:43 | ||||||||||||||||||||||||||||||||||||||
samcv | hmm that could have happened too | ||||||||||||||||||||||||||||||||||||||
err actually. no not that. it ran a pager as a launched process | |||||||||||||||||||||||||||||||||||||||
timotimo | can't immediately reproduce, so maybe it got fixed since i last tried | ||||||||||||||||||||||||||||||||||||||
though of course when i kill the pager it'll give a nasty exception and error output :) | 21:44 | ||||||||||||||||||||||||||||||||||||||

lizmat | FWF, prompt uses 0 CPU for me | 21:44 | |||||||||||||||||||||||||||||||||||||
*FWIW | |||||||||||||||||||||||||||||||||||||||
Zoffix | lizmat: there's sorta an issue for that already R#1354 | 21:45 | |||||||||||||||||||||||||||||||||||||
synopsebot | R#1354 [open]: github.com/rakudo/rakudo/issues/1354 Some operations with zero-denominator Rationals are broken | ||||||||||||||||||||||||||||||||||||||
Zoffix | Basically all the math with ZDRs is broken :) | ||||||||||||||||||||||||||||||||||||||
lizmat | so no need to add another issue then :-) | 21:46 | |||||||||||||||||||||||||||||||||||||
samcv | not sure what i'm doing but i get two processes each using 33% cpu | ||||||||||||||||||||||||||||||||||||||
tbrowder___ | one more question: when an nqp object is used in the $*W.add_constant method, does that create a QAST node? i havenāt tested it yet, but looking at various nqp code it seems like that is what is happening. | ||||||||||||||||||||||||||||||||||||||
samcv | with MoarVM/tools/update-changelog.p6 i noticed yesterday | ||||||||||||||||||||||||||||||||||||||
timotimo | oh? i thought add_constant just makes the object available in the serialization context, so that it can be used inside WVal and such | 21:47 | |||||||||||||||||||||||||||||||||||||
though i don't think you have to do that manually any more? | |||||||||||||||||||||||||||||||||||||||
not entirely sure | |||||||||||||||||||||||||||||||||||||||
maybe it's also about re-using constant values? | |||||||||||||||||||||||||||||||||||||||
samcv | hmm it seems to be using cpu when not in prompt as well | 21:49 | |||||||||||||||||||||||||||||||||||||
timotimo | you could "perf record" to get some data of what it's doing, or "perf top" to see what kinds of things are using cpu time | 21:51 | |||||||||||||||||||||||||||||||||||||
jnthn | tbrowder___: iirc, the op to do a lookup starts in the *caller* frame, not the current one, so some of them do things like `token blah($*foo = nqp::getlexdyn('$*foo')) { }` or whatever and are looking up the caller one. | ||||||||||||||||||||||||||||||||||||||
About assigning them, no idea :) | |||||||||||||||||||||||||||||||||||||||
tbrowder___ | is serialization step for an object the same as boxing? | 21:52 | |||||||||||||||||||||||||||||||||||||
21:52
pmurias left
|
|||||||||||||||||||||||||||||||||||||||
jnthn | No | 21:52 | |||||||||||||||||||||||||||||||||||||
Serialization is about making stuff survive the compilation boundary | |||||||||||||||||||||||||||||||||||||||
samcv | timotimo: on it | 21:53 | |||||||||||||||||||||||||||||||||||||
jnthn | Boxing is sticking a native value into an object | ||||||||||||||||||||||||||||||||||||||
tbrowder___ | then all that stuff happens in compilation i guess | 21:54 | |||||||||||||||||||||||||||||||||||||
samcv | hmm the kernel is using 27% of cpu time in read_hpet | 21:55 | |||||||||||||||||||||||||||||||||||||
not sure if that's related | |||||||||||||||||||||||||||||||||||||||
tbrowder___ | timotimo: thanks | 21:56 | |||||||||||||||||||||||||||||||||||||
jnthn: thanks | |||||||||||||||||||||||||||||||||||||||
samcv | ok when i use the callgraph i get __clone from libc taking up 60% of the cpu inclusive | 21:59 | |||||||||||||||||||||||||||||||||||||
jnthn | .oO( What the fork? ) |
22:00 | |||||||||||||||||||||||||||||||||||||
samcv | ok scratch that. so read_put seems to be getting called due to MVM_platform_sleep and MVM_platform_now | ||||||||||||||||||||||||||||||||||||||

samcv | jnthn: printf "%f" seems to show it starts sleeping for 0.000000 seconds repeatedly? | 22:16 | |||||||||||||||||||||||||||||||||||||
jnthn | samcv: Hm, no idea...where's that happening? | 22:18 | |||||||||||||||||||||||||||||||||||||
samcv | where as in in moarvm? i'm not sure it just has ??? for what the caller of MVM_platform_sleep | ||||||||||||||||||||||||||||||||||||||
jnthn | If gdb you might be able to try p MVM_dump_backtrace(tc) | 22:20 | |||||||||||||||||||||||||||||||||||||
samcv | ok | ||||||||||||||||||||||||||||||||||||||
22:20
cognominal-p6 left
|
|||||||||||||||||||||||||||||||||||||||
jnthn | ??? for caller usually means "jitted code"; you can MVM_JIT_DISABLE=1 to get a better backtrace in that case | 22:20 | |||||||||||||||||||||||||||||||||||||
samcv | yeah | 22:21 | |||||||||||||||||||||||||||||||||||||
well it says no tc in current context. what do i do now (trying to do p MVM_dump_backtrace(tc)) | |||||||||||||||||||||||||||||||||||||||
jnthn: with JIT disabled it never sleeps for 0 seconds | 22:22 | ||||||||||||||||||||||||||||||||||||||
but still uses lots of cpu. no clue why that would be.. | 22:23 | ||||||||||||||||||||||||||||||||||||||
jnthn | Maybe `where` and then look for a frame with a tc and then frame n and then try it | 22:24 | |||||||||||||||||||||||||||||||||||||
samcv | uh still getting no symbol "tc" | 22:27 | |||||||||||||||||||||||||||||||||||||
"frame X"; "p MVM_dump_backtrace(tc)" and it says no "tc" in like MVM_io_reaad_bytes | |||||||||||||||||||||||||||||||||||||||
though that seems to be where it is when i pause it and check | 22:28 | ||||||||||||||||||||||||||||||||||||||
jnthn | Odd. Do you have a build with debug symbols or and --optimize=0? | ||||||||||||||||||||||||||||||||||||||
(Sometimes gdb can't recover things properly when there's enough opt) | 22:29 | ||||||||||||||||||||||||||||||||||||||
samcv | ah silly me for some reason i didn't built with debug symbols! | ||||||||||||||||||||||||||||||||||||||
jnthn: here we go gist.github.com/5f00b0c63d09578a7b...7a2b1bd23a | 22:32 | ||||||||||||||||||||||||||||||||||||||
jnthn | Odd, and it's being run at the console (e.g. stdin would be a tty)? | 22:33 | |||||||||||||||||||||||||||||||||||||
samcv | yah it's on console | 22:34 | |||||||||||||||||||||||||||||||||||||
Zoffix decides to postpone the bump until tomorrow morning | |||||||||||||||||||||||||||||||||||||||
It's a bit harder than changing a letter, since at some point during parsing we must determine that we must upgrade to 6.d and make any later version switches throw | |||||||||||||||||||||||||||||||||||||||
samcv | and weirdly it starts sleeping for 0.01 secs, then sleeps for 1.504436s and then starts sleeping for 0 s | ||||||||||||||||||||||||||||||||||||||
but with no jit it sleeps for 0.01s consistently | 22:35 | ||||||||||||||||||||||||||||||||||||||
both seem to use about the same amount of cpu | |||||||||||||||||||||||||||||||||||||||
jnthn | Hm, but what does ths sleep? | ||||||||||||||||||||||||||||||||||||||
It can loop at github.com/MoarVM/MoarVM/blob/mast...ile.c#L146 | 22:36 | ||||||||||||||||||||||||||||||||||||||
But only if it's getting back EINTR | |||||||||||||||||||||||||||||||||||||||
samcv | jnthn: that doesnt seem to be where it's looping at L146 | 22:40 | |||||||||||||||||||||||||||||||||||||
i added a print and am not getting any repeated prints | |||||||||||||||||||||||||||||||||||||||
or at least. it isn't looping.. or something | 22:41 | ||||||||||||||||||||||||||||||||||||||
jnthn is confused :) | |||||||||||||||||||||||||||||||||||||||
Zoffix | <GeorgeTakei> Ohh, myyy! | 22:56 | |||||||||||||||||||||||||||||||||||||
samcv | jnthn: does this backtrace make sense? gist.github.com/samcv/444a6690a401...2f4cf7c389 | 22:58 | |||||||||||||||||||||||||||||||||||||
i set a breakpoint for MVM_platform_sleep | |||||||||||||||||||||||||||||||||||||||
jnthn | Is that MVM_fixed_size_free really true? | 22:59 | |||||||||||||||||||||||||||||||||||||
jnthn finds it very unlikely | |||||||||||||||||||||||||||||||||||||||
I suspect it's just confused | |||||||||||||||||||||||||||||||||||||||
Can you frame 6 and p MVM_dump_backtrace(tc) ? | 23:00 | ||||||||||||||||||||||||||||||||||||||
samcv | ok it seems to be confused i ran it again and it's showing the right order i suppose? | 23:04 | |||||||||||||||||||||||||||||||||||||
anyway i get this now gist.github.com/c11ec6ec27e322f226...de7d9a1245 | 23:05 | ||||||||||||||||||||||||||||||||||||||
jnthn | I'm pretty sure it's the fixed_size_free is just confusion, but the 0 looks legit. Hmm. | 23:08 | |||||||||||||||||||||||||||||||||||||
samcv | yeah it seems very confused. it won't let me print out MVM_dump_backtrace | 23:09 | |||||||||||||||||||||||||||||||||||||
jnthn | Hm, even at frame 6? | ||||||||||||||||||||||||||||||||||||||
samcv | The program being debugged was signaled while in a function called from GDB. | ||||||||||||||||||||||||||||||||||||||
GDB remains in the frame where the signal was received | |||||||||||||||||||||||||||||||||||||||
jnthn | oops | ||||||||||||||||||||||||||||||||||||||
Hm | |||||||||||||||||||||||||||||||||||||||
samcv | oh it seems to have moved, but i have no output | ||||||||||||||||||||||||||||||||||||||
and if i continue mvm segfaults | |||||||||||||||||||||||||||||||||||||||
jnthn | I'd wonder if the JIT of sleep is wrong and causing a bogus 0 there but I think you said the JIT being disabled doesn't remove the problem you're seeing? | 23:10 | |||||||||||||||||||||||||||||||||||||
The JIT code looks fairly legit too | |||||||||||||||||||||||||||||||||||||||
Oh, though... | |||||||||||||||||||||||||||||||||||||||
samcv | yeah it doesn't remove it. though the bogus 0 is maybe an issue too | ||||||||||||||||||||||||||||||||||||||
i mean maybe it was worse... it sleeps a LOT when it's trying to sleep 0 seconds again and again | 23:11 | ||||||||||||||||||||||||||||||||||||||
jnthn | sleep takes a dobule | ||||||||||||||||||||||||||||||||||||||
*double | 23:12 | ||||||||||||||||||||||||||||||||||||||
samcv | uh seems to be in ThreadPoolSchduler.pm6 | ||||||||||||||||||||||||||||||||||||||
SETTING::src/core/ThreadPoolScheduler.pm6:624 where it's sleeping | |||||||||||||||||||||||||||||||||||||||
i was able to run it when i disabled JIT | |||||||||||||||||||||||||||||||||||||||
jnthn | And the JIT seems to be indicating the argument is KaliÅ”nickĆ” | ||||||||||||||||||||||||||||||||||||||
hah | |||||||||||||||||||||||||||||||||||||||
Zoffix | :) | 23:13 | |||||||||||||||||||||||||||||||||||||
jnthn | MVM_JIT_REG_VAL | ||||||||||||||||||||||||||||||||||||||
But I think it should be MVM_JIT_REG_VAL_F | |||||||||||||||||||||||||||||||||||||||
Here: github.com/MoarVM/MoarVM/blob/mast...ph.c#L3271 | |||||||||||||||||||||||||||||||||||||||
I think as it stands sleep gets a junk value | 23:14 | ||||||||||||||||||||||||||||||||||||||
samcv | i will try changing that | 23:15 | |||||||||||||||||||||||||||||||||||||
well that fixes that issue! | 23:16 | ||||||||||||||||||||||||||||||||||||||
at least with the bogus sleep times | |||||||||||||||||||||||||||||||||||||||
timotimo | i see the prolem with sleep | ||||||||||||||||||||||||||||||||||||||
Zoffix | Hm.... "Stage parse : Missing or wrong version of dependency 'gen/moar/Perl6-Grammar.nqp' (from 'gen/moar/CORE.d.setting')" | ||||||||||||||||||||||||||||||||||||||
timotimo | ah, jnthn also finds it | 23:17 | |||||||||||||||||||||||||||||||||||||
Zoffix | Had that in 6.c setting, but I stuck ! $*COMPILING_CORE_SETTING into the default lang set up and now it dies in 6 setting :( | ||||||||||||||||||||||||||||||||||||||
samcv | hmm maybe i was doing something wrong. because i'm testing again and moarvm is using hardly any cpu now | ||||||||||||||||||||||||||||||||||||||
\o/ | |||||||||||||||||||||||||||||||||||||||
jnthn | \o/ | 23:18 | |||||||||||||||||||||||||||||||||||||
samcv | so that seems to have done it | ||||||||||||||||||||||||||||||||||||||
Zoffix | \o/ | ||||||||||||||||||||||||||||||||||||||
samcv | glad we could find this bug and fix it. my laptop's battery life thanks you | ||||||||||||||||||||||||||||||||||||||
Zoffix | $*COMPILING_CORE_SETTING ain't set when doing CORE.d | 23:20 | |||||||||||||||||||||||||||||||||||||
jnthn | Zoffix: I think it goes on whether --setting=NULL or whatever | 23:21 | |||||||||||||||||||||||||||||||||||||
Zoffix | Thanks. Found it | 23:22 | |||||||||||||||||||||||||||||||||||||
jnthn | (Can't remember exactly what we pass) | ||||||||||||||||||||||||||||||||||||||
samcv | cool. fix commited :) | 23:24 | |||||||||||||||||||||||||||||||||||||
i'm guessing this should affect other workloads too | 23:25 | ||||||||||||||||||||||||||||||||||||||
jnthn | Indeed...very glad to have that fixed | 23:26 | |||||||||||||||||||||||||||||||||||||
samcv++ | |||||||||||||||||||||||||||||||||||||||
samcv | seems to be more responsive too | ||||||||||||||||||||||||||||||||||||||
jnthn | Wonder if that was the cause of an unexplained performance drop-off on one of my customer's heavily threaded apps | ||||||||||||||||||||||||||||||||||||||
(Wasn't a big enough drop-off to be a priority to dig into) | 23:27 | ||||||||||||||||||||||||||||||||||||||
timotimo | today i watched the stream from react conf and there's been like five talks already that were valuable to moarperf <3 | ||||||||||||||||||||||||||||||||||||||
jnthn | Nice :) | 23:28 | |||||||||||||||||||||||||||||||||||||
Zoffix | timotimo: maybe that bug we were trying to fix is also fixed? | 23:30 | |||||||||||||||||||||||||||||||||||||

timotimo | hm, not so sure about that | ||||||||||||||||||||||||||||||||||||||
jnthn | (And so rendered the frame with the sleep jittable when it wasn't before) | ||||||||||||||||||||||||||||||||||||||
timotimo | huh, a sleep could have been in there? | ||||||||||||||||||||||||||||||||||||||
