Hi,
I am not subscribed to the list yet, and I would appreciate it if all replies
could be CCed to me :).
I have two questions regarding epoll. The epoll code that I am using can all
be found in the file here for those interested:
https://svn.enlightenment.org/svn/e/trunk/ecore/src/lib/ecore/ecore_main.c
1) Is there any known reason why adding fds to an epoll fd would begin to slow
down dramatically after ~6000 fds are added? It is entirely possible that the
problem is not epoll at all, but I wanted to ask and see if there was some O(n)
code somewhere that was known.
2) If a select on an epoll fd (not one inside the epoll, the actual epoll fd
itself) returns EBADF, is there a way to determine which fd is causing the
error and then remove it? I am occasionally running into this issue, and it
seems to be caused by code which I do not necessarily control closing a fd that
is part of my epoll fd without my knowledge (meaning that the closed fd is
still in epoll).
Thanks!
