AIO is not supported on this machine!

[ziziwuwu]

After upgrade to 1.6.5, I got "AIO is not supported on this machine!" in the error.log.
after check the difference between 1.5.10 and 1.6.5, it's issue of 1.6.5, not sure it's done on purpose.

for examples, source http/httpsession.h,

in 1.5.10,

#include <edio/aioeventhandler.h>

in 1.6.5

#include <edio/eventhandler.h>

LS_AIO_USE_AIO is defined in aioeventhandler.h, all code depends on that var is not compiled.

void HttpServer::enableAioLogging()
{
#if defined(LS_AIO_USE_AIO)
#endif // defined(LS_AIO_USE_AIO)
    LS_NOTICE("AIO is not supported on this machine!");
}

Bump. I'm seeing this in a new install (CentOS 8 VPS) and wondering if it's important. No explanation was given ^

How did you install or upgrade?

How did you install or upgrade?

Installed from the repo http://rpms.litespeedtech.com/centos/litespeed-repo-1.1-1.el8.noarch.rpm

What does AIO do? Logging?
Is there a setting in the conf that I can try?

AIO is Async IO, it is about the sendfile.
It is enabled on linux and FreeBSD. If not enabled, it is not an error.
