raiph | here's what the html source is for one bit: "<pre>$ perl6 ./main.p6 --help Usage: tmp.p6</pre>" | 00:29 | |
that's from your advent | |||
immediately preceded by "<p>And now, the USAGE is correct:</p>" | 00:30 | ||
vendethiel | raiph: how old is your rakudo :-)? | ||
raiph | not the gist, but perl6advent.wordpress.com/2014/12/2...t-of-main/ | ||
vendethiel | raiph: how old is your rakudo ? | 00:31 | |

i'm just reading the page | 00:32 | ||

vendethiel: how far off am I thinking `subset` might reasonably have been called `ducktype`? | 00:39 | ||
vendethiel | it's not part of it | ||
raiph | completely unrelated? | 00:40 | |
vendethiel | it's part of it*. My bad. | ||
00:41

|
|||
vendethiel | raiph: you can see subset as 1) type alias 2) untagged type union/intersection 3) duck typing (.^can) 4)... | 00:42 | |
raiph | ok, yeah, that's the sort of thing i was thinking, thx | 00:43 | |
yeah, ducktype would not do subset justice, thx | 00:44 | ||
what's 4)... ? :) | |||
vendethiel | something like the custom wheres | 00:47 | |
I don't consider "* > 10" to be "duck typing" | 00:48 | ||

moritz | Juerd: the feather replacement server is now running, and the perl6.org DNS has been updated to point to the new server | 07:41 | |
Juerd | moritz: That's great! | ||
moritz | Juerd: but the DNS has max-TTL of 7 days, which will end on Christmas Eve | ||
Juerd: so my plan is to then shut down apache on feather, see if anybody complains | 07:42 | ||
Juerd: also add a notice to the MOTD that feather will be shut down | |||
FROGGS | m: say "raw characters\r\n".encode | ||
camelia | rakudo-moar 284c09: OUTPUT«Buf:0x<72 61 77 20 63 68 61 72 61 63 74 65 72 73 0d 0a>» | ||
FROGGS | dsm: ^^ | 07:43 | |
moritz | that's just Buf -> Buf :-) | ||
Juerd | moritz: How about 2 and 3? | ||
moritz | Juerd: 3 was only used for dalek, that one is migrated | ||
Juerd: 2 hosted the perl6.org websites, so that's also covered | |||
Juerd | Dalek had its own virtual server? Haha :) | ||
dsm | m: sub f(Buf $b) {}; f("raw characters\r\n".encode) | ||
camelia | rakudo-moar 284c09: OUTPUT«Type check failed in binding $b; expected 'Buf' but got 'utf8' in sub f at /tmp/rFYl1buBq9:1 in block <unit> at /tmp/rFYl1buBq9:1» | ||
Juerd | moritz: Thanks for taking care of all this | 07:44 | |
moritz | Juerd: 1 is what worries me a bit, because it has > 100 user accounts, and we have < 10 on the new server | ||
Juerd | It never did come with any guarantees | ||
moritz | Juerd: do you have the infrastructure to archive the homes on feather1 for a few months? | ||
Juerd | Of course | ||
I'll simply tgz the home dirs | 07:45 | ||
Or txz perhaps :) | |||
dsm | m: sub f(Buf $b) {}; f(Buf.new: "raw characters\r\n".encode) | 07:46 | |
camelia | ( no output ) | ||
dsm | are there a reason why utf8 type exists? | 07:48 | |
moritz | dsm: yes; to encode the information that a byte stream is valid UTF-8 | ||
Juerd | Is, or is supposed to be? | 07:49 | |
moritz | is | ||
07:49
rindolf joined
|
|||
dsm | then if I want to pass byte stream which is valid UTF-8 into function like 'f' above, should I convert it to Buf type everytime? | 07:49 | |
Juerd | 'cause Perl 5's "utf8 flag" sort of encodes the same information, and having it on data that isn't actually valid UTF-8 can lead to security holes. | ||
Also, "encode" is a weird term for going from bytes-with-metadata to bytes-without-metadata. | 07:50 | ||
Are you sure it's utf8 we're talking about, not unicode? | |||
moritz | Str (on which you call "encode") isn't bytes | 07:51 | |
it's list of codepoints, and in future list of graphemes | |||
Juerd | Str isn't utf8 either | ||
moritz | correct | 07:52 | |
Juerd | Don't call it that, or allow others to call it that. It scares me to death :P | ||
moritz | the .ccache dirs in the feather homes make up a total of 2.5G :-) | 07:57 | |
Juerd | Yeah, they used to be shared | 07:59 | |
Which theoretically shouldn't be an issue, but in practice lead to weird bugs | |||
moritz deletes all of those that haven't been touched in half a year | 08:00 | ||
dsm | I'm talking about compatibility of utf8 type and Buf type | 08:01 | |
Juerd | dsm: As I understand it, there is no utf8 type. | ||
dsm: Do you mean Str? | |||
moritz | Juerd: there is an utf8 type | ||
Juerd: it's a buffer type that enforces utf-8 validity | |||
dsm | m: "raw characters\r\n".encode.WHAT.say | ||
camelia | rakudo-moar 284c09: OUTPUT«(utf8)» | ||
moritz | m: say utf8 ~~ Blob | 08:02 | |
camelia | rakudo-moar 284c09: OUTPUT«True» | ||
Juerd | I see | ||
08:02
kst joined
|
|||
Juerd | Why is it called utf8, not Utf8? | 08:02 | |
dsm | sorry | ||
moritz | because it's a native/low-level/packed type | ||
Juerd | Ah | ||
moritz | just like int vs. Int | 08:03 | |
Juerd | Low level, but it does enforce things. Sounds a bit odd. | ||
dsm | if I want to pass type constraint, should I convert it into Buf type everytime? | ||
moritz | dsm: what type constraint should it pass? | ||
dsm: and why is that type contraint Buf and not Blob? | |||
dsm | pass a type constraint? sorry about my English | ||
moritz | dsm: who made the type constraint? | 08:04 | |
dsm | github.com/rakudo/rakudo/blob/nom/...t/Async.pm here write method | ||
moritz | dsm: should probably be corrected to Blob | 08:05 | |
dsm | thanks | ||
moritz | dsm: can you test it locally if it works when changed to Blob? | 08:06 | |
dsm | i'll try | ||

mathw | well... it's still nice | 09:58 | |

nwc10 | moritz: so that it can't DOS the machine by filling the real /tmp ? | 10:11 | |
moritz | nwc10: or if it's compromised, read other people's /tmp/ files, or try IPC via socket files in /tmp (for example with mysql) | 10:12 | |
I'm stepping throw 0pointer.net/public/systemd-nluug-2014.pdf | |||
nwc10 | aha, interesting. thanks | 10:13 | |
moritz | I've now given both dalek services (IRC and HTTP) PrivateTmp=yes, PrivateDevices=yes, ProtectSystem=full, NoNewPrivileges=yes | 10:14 | |
the ProtectSystem=full prevents write access to /usr and /etc | |||

I was able to easily add https to pl6anet.org within a few mins | 10:30 | ||

psch | mathw: there was a comment on my advent post. i think the cleanest solution would be always treating our Int as long and require native int coercion for narrower types | 10:48 | |
mathw: although that'd mean using BigInts towards Java needs to always work with the Java BigInts, whatever they're called | |||
but i guess shoving our Int into a Java BigInt constructor could be made to work somehow, probably with a module though | 10:49 | ||
10:49

mathw | how would you choose between void foo(long a) and void foo(BigInteger a) | 11:01 | |
psch | it depends :) | 11:02 | |
i mean, our Int are arbitrarily sized, i.e. pretty much BigInts | |||
11:02
Mso150 left
|
|||
psch | so if we can/have to we probably should marshal them to BigInteger on the Java size | 11:03 | |
and explicitly choosing the long candidate would be with $cl.foo(int64($myInt)) | 11:04 | ||
i'm not sure if that coercer works on the perl6-side yet though, but it definitely isn't implemented for the interop | 11:05 | ||
if we didn't want to rely on BigInteger as a default-marshalling target we'd always go take the long candidate and calling the BigInteger candidate would mean creating a java BigInteger object first | 11:08 | ||
although i'm fairly sure it'd be safe to assume that any jvm we run on has BigInteger | 11:09 | ||

Juerd | moritz: It's much less trouble to set up separate services on a dozen separate virtual servers, than to properly use selinux on a single one :) | 12:47 | |
moritz | Juerd: i get that impression too, especially if you have some sort of automated configuration management | 12:48 | |
Juerd | Which config management tool do you use? I like Ansible. | 12:49 | |
moritz | none privately; $work uses puppet | ||
(but at work I don't do ops, so I'm in little contact with it) | |||
Juerd | Didn't want Puppet myself because it requires Ruby on the servers and it uses a pull model. | 12:50 | |

masak | I've never done dynamic params in a BUILD either. | ||
lizmat | no, vars with tiwgils | ||
masak | well, that's a completely different twigil :) | ||
lizmat | *twigils | ||
masak | I guess I wasn't sure how special-cased it was... | ||
I wouldn't have been that surprised if dynamicals wouldn't work like that. | |||
[Coke] | now that jnthn++ fixed os x, upgrading xcode... | 21:26 | |
lizmat | I guess in a way, they're the easiest, as they're completely runtime | ||
[Coke] | lizmat: unless you'd recommend against? | ||
lizmat | well... let me double check with a fresh tarball | ||
psch | for me, the surprising bit is probably easiest summarized as "signature declarations are actually the same as explicit declarations" | 21:27 | |
which has "dynvars work" as fallout, and could've been obvious with BUILD | 21:28 | ||
the *-sigil is somewhat trait-y, and thus we get what masak demonstrated | 21:29 | ||
lizmat | [Coke]: are you on Mavericks or Yosemite ? | ||
