pcntl needed?

Just curious if it’s really needed, just reinstalled my vps and switched to php 5.4(And as always, I run nginx) and noticed this error on a fresh install.

The following PHP functions (which may be necessary to run Textpattern) are disabled on your server: pcntl_alarm, pcntl_fork, pcntl_waitpid, pcntl_wait, pcntl_wifexited, pcntl_wifstopped, pcntl_wifsignaled, pcntl_wexitstatus, pcntl_wtermsig, pcntl_wstopsig, pcntl_signal, pcntl_signal_dispatch, pcntl_get_last_error, pcntl_strerror, pcntl_sigprocmask, pcntl_sigwaitinfo, pcntl_sigtimedwait, pcntl_exec, pcntl_getpriority, pcntl_setpriority,

I remember reading that it’s bad to have it enabled on production servers(not that I’m hosting tons of large sites or that my site even gets hits) so I was hesitant to enable it. Thought I would ask before I did enable it because if it’s not really needed and it’s not really good to run on a production server then meh. :p

No, AFAIK, txp diagnostics is too zealous here.

If we truly don’t need it – and honestly I’ve never seen a sniff of it in the code – then let’s just ditch the checks in Diagnostics.

The manual says

Process Control should not be enabled within a web server environment and unexpected results may happen if any Process Control functions are used within a web server environment.

So we shouldn’t rely on PCNTL anywhere in the code, me deduce. And Pete’s demo site runs without.

Re: pcntl needed?

The pcntl_* stuff appears because it’s a part of the Ubuntu (and possibly Debian) PHP distribution.

(Actually, Pete just suppressed the warning…ahem…but don’t tell anyone.)
