ObjFW  History of src/OFKernelEventObserver_poll.h of 0509d7a844e6afd3

Forgot to add 2017, even though I already did quite some changes in
2017. file: [ae0472f750] check-in: [44f45c2e35] user: js, branch: trunk, size: 826 [annotate] [blame] [check-ins using] [diff]

_readObjects must only be changed from the thread running the observer
and not from a thread adding or removing objects to observe. This is
already handled by the locked queue used by poll and select, so the best
way to solve this is to use the locked queue for kqueue and epoll as
well. file: [560881d237] check-in: [45518ae7b7] user: js, branch: trunk, size: 823 [annotate] [blame] [check-ins using] [diff]

While at it, also update the mail address. file: [4f7085394a] check-in: [2a27cf3000] user: js, branch: trunk, size: 847 [annotate] [blame] [check-ins using] [diff]

This moves the locked queue for actions to
OFKernelEventObserver_LockedQueue, which is now used for select and
poll, but skipped for kqueue and epoll, as they natively support changes
from another thread.

This fixes the problem that removing an object is delayed until the next
observe call - at which point it might have already been closed, meaning
the fd is no longer available. This was mainly a problem with kqueue, as
closing the fd already removed it from the kqueue, which then resulted
in an error being returned when trying to manually remove the fd from
the kqueue. file: [c6cbfa2ee8] check-in: [e9b4700cb6] user: js, branch: trunk, size: 843 [annotate] [blame] [check-ins using] [diff]

Using __nonnull directly doesn't work on systems using glibc, as glibc
defines __nonnull as a parameterized define. While this does not fix the
problem of Clang introducing __nonnull even though it conflicts with
glibc, this at least means it's possible again to compile things with
versions of Clang that don't support __nonnull on systems with glibc. file: [2642239f58] check-in: [b7097a67b6] user: js, branch: trunk, size: 819 [annotate] [blame] [check-ins using] [diff]
