I'm just far enough into Robert Love's "Linux System Programming" that I
think the solution to FastCGI may be much simpler than I'd previously
thought.
I think we need a new command that launches a specified process but in a
way that uses a call to "fork" to pass file descriptors (which include
sockets and other I/O info) to the child process.
In many ways it would work very similarly to the existing "open
process", but allow params to give the child process access to things
like socket connections, pipes, files, etc. the parent process has
access to at the time the child process is launched.
It would seem least intrusive on the code base to implement it as a new
command, perhaps called "fork".
That said, I have to admit the risk of Dunning-Kruger effect here: I'm
not that far into the book, and my knowledge in this area is far below
my aspirations.
But for those of you more familiar with Linux system programming, do I
misunderstand the difficulty involved?
Forking seems so common in other tools, and not having it appears to be
the one detail standing between where we are now and having not just
FastCGI, but also being able to build truly excellent application
servers on par with Node.js and other similar systems.
LiveCode is a great language, and if we had the ability to fork we
should be able to build a wide range of powerful, scalable, efficient
systems, breaking far beyond the limitations of CGI we're limited to now.
If all we need is a new command to wrap the Linux "fork" call, after I
finish Love's book I may brush up on my C skills and give it a go.
But who wants to wait for that. Is there anyone in our community who
could do this now?
Do I misunderstand what's needed here?
