MasterDuke i just ran three times and they seemed to take about the usual time. but i did consistently get fails in t/spec/S32-str/utf8-c8.t `Non-zero exit status: 255 Parse errors: Bad plan. You planned 66 tests but ran 33.` 08:46
`Unexpected named argument 'bin' passed in block at t/spec/S32-str/utf8-c8.t line 139 in block <unit> at t/spec/S32-str/utf8-c8.t line 106` 08:47
lizmat MasterDuke are you on MacOS ?
MasterDuke linux 08:48
lizmat hmmm.... I thought that error was MacOS specific
I looks like I borked it 08:49
otoh, ":bin" is not a documented parameter to spurt

:bin is not a parameter to spurt

Spurting a Blob implies binary writing. This was previously not caught as the named parameter was just passed on into oblivion.
lizmat MasterDuke ^^
MasterDuke lizmat++ all clear now, times look normal 08:54
lizmat ok, then it must be something on my machine that slowed down the spectest 08:55
ahh.... it may have been my image backup running still 08:56
MasterDuke btw, anyone know what the long delay is when starting a spectest before the tests actually start? 09:00
the fudging i assume? 09:01
lizmat precomping a lot ? 09:09
MasterDuke well. it happens even on repeated runs with no code changes
and wow, spectest6 takes 376s for me, but spectest takes 128s 09:10
lizmat how many cores ? 09:11
MasterDuke 8 real, 16 virtual 09:15

Fix for NQP issue GH #632
The issue was triggered by a parser error after a reformat of file

[Tux] Do I need anything specific to make "class ๐ŸŽ {" a legal statement? 11:21
lizmat a slang, probably 11:22
m: dd "๐ŸŽ".uniprop # that's unacceptable in identifiers 11:24
camelia "So"
lizmat otoh, perhaps with meta-programming
jnthn You can write `class ::('๏ฟฝ') {` I think 11:26
To give it that name 11:27
Though you'll likely need to do similar at teh point of usage
lizmat m: class ::("๐ŸŽ") { }; dd ๐ŸŽ.new # indeed

lizmat I guess changing the .ident token should be enough ? 11:28
or the identifier token, probably
jnthn identifier 11:29
well, or ident I guess
[Tux] I wanted to add raku to a quest in FB, and I thought this would be showing the power of raku

lizmat sena_kun: that was Patrick Bรถker's work, right ? 11:37
sena_kun lizmat, "that" being?
Azure integration?
lizmat the AzureCI pipeline ?
yes 11:38
sena_kun lizmat, yes.
lizmat oki
sena_kun I think it will be helpful to present it so that core devs wouldn't be too surprised or unpleasantly surprised. 11:39
lizmat yeah, it's going to be the main article :-) 11:40
doesn't AzureCI also make releasing Rakudo easier ?
in that it produces build artefacts ? 11:41
sena_kun lizmat, I don't think so.
lizmat ah, ok
sena_kun lizmat, it mean _possible_ providing of nightly builds for people, but release is Serious Business. 11:42
lizmat ok :-)
sena_kun s/mean/can mean/

patrickb lizmat, sena_kun: AzureCI makes it easier for me to create the precompiled binary builds (the ones that can be downloaded on as now not only MacOS and Linux files can be built on the CI (as was the case with CircleCI), but now also Windows is covered. The work to create the source release is unaffected alas. 11:52
tellable6 hey patrickb, you have a message:
sena_kun lizmat, ignore me then, ^ is truth
lizmat :-) 11:54
patrickb Btw. I'm in search of a backup person that can also create the precompiled release files. I tend to not be available every day which often caused a delay of some days of the release of the binaries. 11:55
sena_kun patrickb, if building is automated (or will be), I can discuss doing that next weekend. 11:56
patrickb The work is comprised of triggering the the build on the CI, downloading the results, sanity checking the files (unzip works, archives have a sane size, ...) and uploading to the server. 11:57
sena_kun patrickb, sounds sane, can try doing it myself next release given there are instructions or you around. 11:58
releasable6, status
releasable6 sena_kun, Next release in โ‰ˆ33 days and โ‰ˆ7 hours. There are no known blockers. Changelog for this release was not started yet
sena_kun, Details:
patrickb It's documented in
sena_kun patrickb, do I need something special to test out archives? A windows box or something, or gnu/linux one is enough? 12:00
patrickb sena_kun: Depends on how much more manual testing you want to give the packages. 12:01
sena_kun Fair enough...
Ok, will look closer after $dayjob 12:02
patrickb I myself don't have access to a MacOS box, so never manually tested those either.
The files get tested during the creation process. No spec tests though.

I'm sure I found this when working on Inline::Perl5 and did the fix, but didn't write tests and left workarounds in Inline::Perl5 as I want it to support older rakudos as well :/

nine This is odd... after establishing that my 2 possible error messages depend on hash order, I audited all our code (yet again). As that yielded nothing, I simply added a die; to all of Map's iterating methods except for .sort. That tripped several places (most of which harmless for sure, the others probably) 18:10
Fixing all those gave me a working build and program really changed it to always fail in the same way. 18:11
So, now I've just got to find the part of my patch that changed this, right? But when I remove the die; it reverts to giving one of two errors.
Despite all the .sort fixes still being in place 18:12
lizmat is it really a die, or throwing an X::AdHoc? 18:13
there's nqp::bindcurhllsym('P6EX' with a hash of exception mapping ?
nine Just a die; and sometimes a die unless $*ALLOW-ITERATION, so e.g. .sort can actually do something
lizmat perhaps exception throwing somehow uses a hash ? 18:14
18:14 Kaeipi left
nine Btw it's not just the message that's different. I either get a bogus "Semicolon form of 'perl5class' without 'unit' is illegal (scope is our)." error, or "Serialization Error: missing static code ref for closure '' (gen/moar/World.nqp:3395)" 18:14
Including sensible back traces
lizmat reverts to the rubber duck role 18:16

lizmat sanity check: files written with utf16-le and utf16-be should also have a BOM, right? 18:20
nine thinks so 18:21
lizmat well, it currently doesn't 18:23
I guess it was overlooked when implementing the -le / -be varianrs

lizmat j: use nqp; dd nqp::backendconfig<be> 18:33
camelia Any
lizmat *sigh*
nine lizmat: why do you need that anyway? 18:36
It would make sense for the JVM to miss that bit. After all hardware abstraction was one of the major selling points of JAva
lizmat to be able to write the correct BOM for utf16-le and utf16-be
nine But how does that depend on the platform endianess? 18:37
lizmat well, "utf16" uses the platform endianness, so I guess I want to be able to correctly write that one, indeed :-)

19:37 brrt left
lizmat nine: The standard also allows the byte order to be stated explicitly by specifying UTF-16BE or UTF-16LE as the encoding type. When the byte order is specified explicitly this way, a BOM is specifically not supposed to be prepended to the text, and a U+FEFF at the beginning should be handled as a ZWNBSP character. Most applications ignore a BOM in all cases despite this rule. 20:06
from 20:07
I guess that's another few hours wasted to learn that :-( 20:09
nine A rather odd feature of the standard if you ask me 20:11
lizmat well, yeah, since you can write a file with "utf16" and then read it with "utf16-le" on most hardware 20:13
so the utf16-le *will* ignore the BOM in that case
vice-versa: writing with utf16-be and then reading with utf16 will *not* see a BOM, and thus read garbage on most hardware 20:14
whereas it *would* have written a BOM, it could have complained 20:15
looks like nqp::decode will throw away any BOM regardless of endianness? 20:19
no, it actually "does the right thing" 20:21
m: dd,255,0,97,0,98).decode("utf16") 20:22
camelia "ab"
lizmat m: dd,255,0,97,0,98).decode("utf16be")
camelia "๏ปฟab"
lizmat m: dd,255,0,97,0,98).decode("utf16le")
camelia "\x{FFFE}ๆ„€ๆˆ€"
lizmat well, not the right thing in this last case: it should have complained about finding a BE BOM when asked to do a LE decoding
m: dd,97,0,98).decode("utf16") 20:23
camelia "ๆ„€ๆˆ€"
