It looks like I need to take an application that depends on select() for spawning subprocesses & IPCing with them (via IPC::Run) and port it to WinNT. I wouldn't mind porting to use poll(), if it's almost as portable as select() is, or maybe only where it is. A fellow named Sean McCune (Cced) will probably be doing most of the hacking on this. We're trying to decide whether to try to add a general solution to the perl guts or do the cheap and dirty thing and make IPC::Run check for OS and choose a different strategy on non-select()able OSs. Clearly any sane individual would take the latter option, but we thought we'd flirt with insanity and see how hard the perlguts route is first. I suspect we're insane: if this were feasible ActiveState would likely have done it long ago. So, is anyone working (really) on this, thinking about it, or interested in contributing advice/time/whatever to such an effort? Nick Ing-Simmons mentioned that there might be some possibility of and interest in porting the new poll() implementation to Win32, IIRC. Personally, I'd love to see IPC::Run's Expect-like & event loop modes work with something beyond TCP sockets on NT, and Event.pm and POE would benefit as well. I need pipes, others could use select() or poll() on listening sockets or files, etc. FWIW, Perforce will be funding some or all of this work on Sean and my's part and they're happy to donate the resulting code. - BarrieThread Next
