digitalmars.D.learn - How to call receiveTimout? (std.concurrency)

Hello and Good morning!



I'm trying to use receiveTimeout:

// ––––
	import 	std.stdio,
			std.concurrency;
	int main(string[] args){
		receiveTimeout(  1000L, (int i){writefln("Received: %d",i);}    ) ;
		return 0;
	}
// ––––

(I removed all the surrounding code above that spawned threads etc.)

Compiler gives me:
	/Library/Compilers/dmd2/osx/bin/../../src/phobos/std/concurrency.d(335):
Error: mismatched
tuple lengths, 2 and 1


I can't see what's wrong? Help!


A look in concurrency.d shows:
// - - 8< - -

	bool receiveTimeout(T...)( long ms, T ops )
	{
	    static enum long TICKS_PER_MILLI = 10_000;
	    return mbox.get( ms * TICKS_PER_MILLI, ops );
	}

// - - 8< - -

       final void get(T...)( T ops )
       {
           static assert( T.length );

           static if( isImplicitlyConvertible!(T[0], long) )
           {
               alias TypeTuple!(T[1 .. $]) Ops;
               assert( ops[0] >= 0 );
               long period = ops[0];
               ops = ops[1 .. $];  // <=== line 335
           }

// - - 8< - -

Well, this looks like a bug to me. Should be

Ops = ops[1 .. $];

Oh, and you could probably make this change yourself.

Ops is a type, isn't it?  Don't you need a variable there?

I agree it's a bug in the original, but I don't think that's the fix.

Ok, thanks!

How does the chain of command/responsibility work here?
Should I file this to bugzilla?

(I'm not able to fix it myself as I haven't built dmd locally. I'm just =
not quite there yet... : )

Simen actually already filed it.  See here:  
http://d.puremagic.com/issues/show_bug.cgi?id=4406.  In the future, just  
go to http://d.puremagic.com/issues and you can file the bug directly.   
It's good to ask on d.learn if you aren't sure.

And this bug isn't in dmd, it's in phobos :)  They are compiled separately  
(in case you are interested in trying your hand at phobos patches).  All  
the releases come with the complete source code, just cd to the src  
directory and type make -f blah.mak where blah is your platform (posix,  
windows, etc.).
