+1, having another incentive to drive libdispatch to be part of the snapshots 
doesn't seem like a bad thing.

 I was wondering if we are only waiting for dispatch to be available on 
 Linux here. In that case, could we have the failing tests (if any) 
 excluded (only on Linux perhaps) and have this merged please? Some of us 
 at IBM would like to work with the current implementation and contribute 
 on top of it.
 
 Thanks!

 Feedback is very welcome.
 
 The tests show what's working, and there are "TODO:" markers throughout 
 the code where applicable.

I think that would make a giant mess. I'm curious how far off we are for having 
lob libdispatch on Linux. I think it would be worth waiting a bit longer I n 
stead of making the code illegible. Just my 2￠.

Re: [swift-corelibs-dev] NSURLSession & libcurl

2016-04-20 Thread Pushkar N Kulkarni via swift-corelibs-dev 
Hi Tony, Daniel, Thanks for your responses. Would it be acceptable if, for now, we check for the availability of Dispatch and conditionally compile calls to it into the current implementation of NSURLSession* (something like the  _HAS_DISPATCH__ macro used in CoreFoundation)? This would make NSURLSession and related classes functional with a custom toolchain that has Dispatch, on Linux. It'd also make them functional on OS X.I realise this may need some code restructuring.Pushkar N Kulkarni,

Re: [swift-corelibs-dev] NSTask and NSFileHandle implementation

2016-04-20 Thread Chris Bailey via swift-corelibs-dev 
Hi Daniel:

Support for DISPATCH_SOURCE_TYPE_READ should be there. If I remember 
correctly its just support for processes and VM memory pressure that isn't 
available.

Wouldn't it still be a huge win to use dispatch for reading from / writing 
to a file descriptor?

Hi Dan: 

The Dispatch sources are mostly complete - unfortunately 
DISPATCH_SOURCE_TYPE_PROC isn't there and it unlikely to be there in a 
hurry. It would ideally need the underlying kqueue library to have 
EVFILT_PROC support, which it doesn't today.

While we’re on the subject, I’ve been out of the loop for a little while: 
how’s the Linux-side implementation of dispatch sources looking these 
days?  In particular, I’m interested in the status of 
DISPATCH_SOURCE_TYPE_READ and DISPATCH_SOURCE_TYPE_PROC. 

Right now, NSTask is using Good Ol’ CFRunLoops for it’s event handling, 
and I’d really like to move that over to GCD as soon as I can.

Hey Alexander, 

I supplied most of the initial implementation of NSTask, but was holding 
off on IO redirection until someone tackled NSFileHandle.  I can’t say if 
anyone else on this list is working on this right now, but if not and if 
you’re really interested in finishing NSFileHandle, I would (very 
happily!) take care of the relevant implementation in NSTask.
