 Re: Can we simplify win32 threading code > > Why not just use the pid in teh name, and have one segment > per backend? > > Being used only for signals you mean? That might work. That was my idea. We'll end up using three global namespace objects (mutex+event+shared memory) instead of one (named pipe), but as we're not talking thousands and thousands of backends in the normal case, this shuold not be a problem I think. And if you do thousands and thousands of backends, you'd better have the memory to support it anyway. I think you'd hit other limits in the win32 port before you hit this one. > I dislike fooling around with the contents of postmaster.pid, > as that will inject platform-specific code into places where > there is none now.

In this way, that's more like the real Unix signals ... Regards, Qingqing |
