SYNOPSIS
use AnyEvent;
use Event::Lib;
# this module gets loaded automatically as required
DESCRIPTION
This module provides transparent support for AnyEvent. You don't have
to do anything to make Event work with AnyEvent except by loading
Event::Lib before creating the first AnyEvent watcher.
The Event::Lib module suffers from the same limitations and bugs as
libevent, most notably it kills already-installed watchers on a file
descriptor and it is unable to support fork. These are not fatal
issues, but Event::Lib itself has many additional bugs such as taking
references to file handles and callbacks instead of making a copy,
causing memory corruption and random crashes. Only Tk rivals it in its
brokenness.
This adaptor module employs the same workaround around the watcher
problem as Tk and should therefore be avoided. (This was done for
simplicity, one could in theory work around the problems with lower
overhead by managing our own watchers).
Event::Lib also leaks file handles and memory and tends to just exit on
problems.
It also doesn't work around the Windows bug of not signalling TCP
connection failures.
Event::Lib does not support idle watchers. They could be emulated using
low-priority timers but as the priority range (and availability) is not
queryable nor guaranteed, and the default priority is likely the lowest
one, this module cannot use them.
Avoid Event::Lib if you can.
