| how is life today? | |||
| jnthn | Well, I slept way later than expected, due to staying up rather late finishing my advent post :) | 10:58 | |

| #london.pm topic, now out of date, reads: Only 11 debugging all-nighters until Christmas | london.pm.org/ | |||
| jnthn | And I have stroopwafels for with coffee | ||
| nwc10 | so, it should have been "advent post all-nighters" instead? | ||
| jnthn | So, life seems OK :) | ||
| nwc10 | is your food and important-stuff delivery firm only operatin in Prague? | 11:00 | |
| nwc10 is still working out how to get interesting things without air freight | |||

| jnthn | nwc10: It is, believe it or not, Tesco Online :) | ||
| nwc10 | aha | ||
| yes. OK | |||
| I wonder if they deliver from Bratislava :-) | |||
| jnthn | I never used the service in Bratislava, 'cus I lived 2 mins walk to 4-story Tesco department store :) | 11:04 | |
| nwc10 | does a non-UK Tesco have a section for "UK products" for expats? | 11:05 | |
| eg cider that is actually cider, and not some evil blend of actual cider bulked up with apple juice and sweetner | |||
| jnthn | Um...yes to the section. | 11:08 | |
| If Strongbow counts then yes, they have it | 11:09 | ||
| Then, there's a bar just up the street that also claims to have cider, though I don't know if it's "actually cider" :) | 11:10 | ||
| nwc10 | um, yes, I agree with the need for clarification | ||
| Strongbow is cider like Bud is beer. | |||
| jnthn | nakup.itesco.cz/cs-CZ/Search/List?s...rch=Search | ||
| nwc10 | but it is, at least, made from the right ingredients | ||
| jnthn | Bud is...beer??! | 11:11 | |

| rurban_ | sometimes it's travis fault, sometimes a real hang | 13:24 | |
| jnthn | grmbl | 13:54 | |
| So it's easy enough to get the "fileno" from a libuv handle | 13:55 | ||
| Except on Windows that's a HANDLE, not a C runtime descriptor | |||
| And there seems to be no way to go from HANDLE to "existing" file descriptor. | |||
| Perl 5 uses FILE * for its I/O, so gets away with already being in C descriptor emulation land. | 13:56 | ||
| nqp-m -e "say(nqp::fileno(nqp::getstdout()))" | |||
| 8 | |||
| :) | |||
| leont | ? | 13:57 | |
| jnthn | leont: Well, I'm only going on a grep of the Perl 5 source :) | ||
| leont: But I'm feeing FILE * being used, which you can _fileno | |||
| leont | I'm pretty sure there is such a function in the Windows API | ||
| jnthn | I'd love to find it if there is one :) | 13:58 | |
| There's this one: msdn.microsoft.com/en-US/library/bdts1c9x.aspx | |||
| But this actually gives a fresh descriptor | |||
| From the HANDLE | |||
| So if you do that on, say, stdin, you get...3. | 13:59 | ||
| And if you do it again on stdin you get 4 :P | |||
| leont | First question: why would you want this? | 14:00 | |
| jnthn | I'm not actually sure whether I do | ||
| leont | File descriptors on Windows are nothing more than a global table that points to HANDLEs | ||
| jnthn | I'm looking into rt.perl.org/Ticket/Display.html?id=126541 | 14:01 | |
| Which wants a way to get the native file descriptor, presumably mostly for passing off to native calls. | |||
| And then I got curious what Perl 5's fileno does, and discovered that on Windows it does managed to give 0..2 for the standard handles. | 14:02 | ||
| *manage | |||
| leont | msdn.microsoft.com/en-us/library/ks2530z6.aspx | ||
| No wait, I wasn't paying attention | 14:03 | ||
| jnthn | That's the opposite way around. | ||
| leont | If you can get away with not exposing either HANDLEs or descriptors, that's a very good thing | ||
| jnthn | Well, that works fine until somebody needs it | ||
| leont | (well, exposing them as nqp::native_descriptor() or some such is ok, but then it comes without any guarantees | ||
| jnthn | Yeah, I'm pondering calling the method .native-descriptor | 14:04 | |
| Which dehuffmanizes it somewhat | |||
| And makes clear it's native, as in "you better care about platform issues" | |||
| leont | The main reason why people need a file descriptor is when implementing an event loop and/or asynchronous IO | 14:05 | |
| FROGGS | nqp::fileno? | ||
| jnthn | FROGGS: Yes, that's what they op ended up being called | ||
| FROGGS | nice that we have it now :o) | ||
| leont | Since we already provide both, this should be a rare need | ||
| jnthn | Just debating semantics :) | ||
| leont: Indeed | |||
| So I'll go with "long method name, and platform specific" | 14:06 | ||
| I don't really want to shut out people doing interesting I/O stuff we don't provide in core over in module space. | |||
| leont | Only piece of p5 I ever wrote that would otherwise need it was a portable sendfile, but given it's actually 5 implementations in one modules that already says a lot about how unportable that is. | 14:07 | |
| leont isn't awake enough to type English | |||
