[MacRuby-devel] Please implement fork() ;-)

[Laurent Sansonetti]

Hi Robert,

fork() itself is easy to implement, the problem is that the program can very easily crash if CoreFoundation or the GC is called inside the child process. This is the reason why we decided to mark it as not-implemented. I do not believe these problems will go away any time soon, I'm afraid.

fork() + immediately exec() should work, but I believe there is already something in Ruby core for that. Otherwise, we could expose something.

What's your use-case exactly? Maybe your problem can also be solved by spawning a new MacRuby process & communicate with it using NSTask.

With the removal of the GIL, and Grand Central Dispatch fork() isn't really needed to achieve concurrency _but_ I have a particular use case that requires fork() and I'd love to implement my use-case in a MacRuby cocoa application.
