Nginx + CentOS 5.5 + aio

Not many people know that the eventfd mechanism used in nginx for aio was backported to CentOS 5.5 in the core of RHEL 5.5 (starting from 2.6.18-194.8.1), and accordingly in CentOS 5.5.

It would seem all is well, but no, several people unsubscribed on the mailing lists that there is a “leak of sockets” which eliminates 4 patches from Maxim Dounin 2 of which are already included in nginx 0.8.53.


In order to test as much as possible AIO on CentOS accepted as many as possible, I suggest downloading the Nginx RPM build for RHEL / CentOS 5.5 with file AIO support.
')
Patches ( 1 2 ) on aio which are not yet included in nginx I applied separately. For problems with AIO, please write to the mailing list dedicated to Nginx. For all problems with the RPM package, write to me.

The remaining options for building the RPM package can be found in the nginx -V output.
