Hi. Is anyone working on std.concurrency? I was recently experimenting while reading the concurrency chapter and have got functioning prototype where spawn, receiveOnly and simple message queue is working. I would be more than happy to share it and contribute to std.concurrency generally, if such contribution is needed.

Thanks,
Igor

Hi Igor,

That's great news. Sean Kelly has build a near-complete prototype. He does not have much time at all these days, so I'm sure he'll appreciate your help. I suggest you sync with him so as to avoid duplicate work. Sean?

I have messaging in place, but the module needs some upgrading to look like TDPL describes.  I just haven't had time to do it yet.  Let me dig up the file and I'll post it.

Good. Then I?will stop working on it.

Andrei, I have a question, if you do not mind.? I understood that?receiveOnly call is?blocking, correct?

Just until you coordinate with Sean. I'm sure your contribution would add a lot of value. Also, don't forget - new ideas are always appreciated!

Correct.

Definitely.  I've been out sick recently but will be back in commission tomorrow.  I'll try and shape up the module then.

Get better soon!

Sean, just in case, I put my stuff here: http://www.curoles.com/j/dstdconcur.html

Get better.

Definitely.? I've been out sick recently but will be back in commission tomorrow.? I'll try and shape up the module then.

Here's the module:

http://www.invisibleduck.org/sean/src/concurrency.d

It just has send and receive so far, but those are tested and work correctly.  For the moment, Tid is a struct and Cid doesn't exist.  I'd like to try and keep Tid and Cid as structs if possible to avoid the need for dynamic allocation when thisTid() is called (using a single shared Tid instance isn't really safe since it could be deleted by the user).  Most importantly, this still doesn't work:

    receive( (int a) {}, (string b) {} );

The compiler still "sticks" on the type of the first delegate in the foreach expansion and errors during compilation.  Once this is fixed I'll add checking for overload conflicts in the receive set, etc.

I tried your code?with removed dynamic allocation on thisTid(), Tid is "alias TID* Tid" where TID is the structure. Interesting that "delete tid" where tid is returned from spawn or thisTid does not actually destroy the structure and thisTid returns correct address, so there is nothing to be afraid of. Do I miss something?

Here is my version:
http://www.curoles.com/j/concurrency.d
