# *** Canary::Stability COMPATIBILITY AND SUPPORT CHECK
# *** =================================================
# ***
# *** Hi!
# ***
# *** I do my best to provide predictable and reliable software.
# ***
# *** However, in recent releases, P5P (who maintain perl) have been
# *** introducing regressions that are sometimes subtle and at other times
# *** catastrophic, often for personal preferences with little or no concern
# *** for existing code, most notably CPAN.
# ***
# *** For this reason, it has become very hard for me to maintain the level
# *** of reliability and support I have committed myself to in the past, at
# *** least with some perl versions: I simply can't keep up working around new
# *** bugs or gratituous incompatibilities, and in turn you might suffer from
# *** unanticipated problems.
# ***
# *** Therefore I have introduced a support and compatibility check, the results
# *** of which follow below, together with a FAQ and some recommendations.
# ***
# *** This check is just to let you know that there might be a risk, so you can
# *** make judgement calls on how to proceed - it will not keep the module from
# *** installing or working.
# ***
# *** The stability canary says: (nothing, it was driven away by harsh weather)
# ***
# *** It seems you are running perl version 5.024000, likely the "official" or
# *** "standard" version. While there is nothing wrong with doing that,
# *** standard perl versions 5.022 and up are not supported by EV.
# *** While this might be fatal, it might also be all right - if you run into
# *** problems, you might want to downgrade your perl or switch to the
# *** stability branch.
# ***
# *** If everything works fine, you can ignore this message.
# ***
# *** Stability canary mini-FAQ:
# ***
# *** Do I need to do anything?
# *** With luck, no. While some distributions are known to fail
# *** already, most should probably work. This message is here
# *** to alert you that your perl is not supported by EV,
# *** and if things go wrong, you either need to downgrade, or
# *** sidegrade to the stability variant of your perl version,
# *** or simply live with the consequences.
# ***
# *** What is this canary thing?
# *** It's purpose is to check support status of EV with
# *** respect to your perl version.
# ***
# *** What is this "stability branch"?
# *** It's a branch or fork of the official perl, by schmorp, to
# *** improve stability and compatibility with existing modules.
# ***
# *** How can I skip this prompt on automated installs?
# *** Set PERL_CANARY_STABILITY_NOPROMPT=1 in your environment.
# *** More info is in the Canary::Stability manpage.
# ***
# *** Long version of this FAQ: http://stableperl.schmorp.de/faq.html

# Welcome to EV configuration. If you are in a hurry, just press return here

#
# POSIX optionally offers support for a monotonic clock source. EV
# can take advantage of this clock source to detect time jumps more
# reliably. Unfortunately, some systems are bound to be broken, so you can
# disable this here: you can completely disable the detection and use of
# the monotonic clock by answering 'n' here. Support for this clock type
# will otherwise be autodetected at both compile- and runtime. (this setting
# currently affects the use of nanosleep over select as well).
#
# Enable optional support for CLOCK_MONOTONIC (y/n)? [y] y
#
# *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** ***
#
#
# POSIX optionally offers support for a (potentially) high-resolution
# realtime clock interface. In a good implementation, using it is faster
# than the normal method of using gettimeofday. Unfortunately, this option
# is also bound to be broken on some systems, and current EV versions do not
# actually call gettimeofday very often, so it defaults to no.
#
# Prefer clock_gettime (CLOCK_REALTIME) over gettimeofday (y/n)? [n] n

#
#
# EV can use various backends with various portability issues. The select
# backend is the most portable and makes for a good fallback, but it can be
# limited to a low number of file descriptors and/or might not compile. If
# you have problems with compiling ev_select.c, you might try to play around
# with disabling it here, or forcing it to use the fd_set provided by your
# OS, via the next question. I highly recommend keeping it in.
#
# Enable select backend (y/n)? [y] y
#
# *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** ***
#
#
# The select backend can operate in two modes. One uses the system-provided
# fd_set and is usually limited to 1024 file descriptors (64 on windows),
# the other requires your header files to define NFDBITS and declare a
# suitable fd_mask type. If you run into problems compiling ev_select.c, you
# can try forcing the use of the system fd_set here.
#
# Force use of system fd_set for select backend (y/n)? [n] n
#
# *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** ***
#
#
# The second very portable backend is poll(2). It does not exist on windows
# and various versions of Mac OS X (and on the other versions it simply
# doesn't work), but works basically everywhere else. It is recommended to use
# the default here unless you run into compile problems in ev_poll.c.
#
# Enable poll backend (y/n)? [y] y
#
# *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** ***
#
#
# Select and poll make it hard to write efficient servers, especially if the
# number of active connections is much lower than the watched ones. GNU/Linux
# systems have a more scalable method called "epoll", which EV can use. For
# this to work, both your kernel and glibc have to support epoll, but if you
# can compile it, the detection will be done at runtime, and EV will safely
# fall back to using select when epoll isn't available. If unsure, accept
# the default.
#
# Enable epoll backend (y/n)? [y] y
#
# *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** ***
#
#
# Similarly to the epoll backend above, EV can take advantage of kqueue on
# many BSD systems. Support for kqueue will be detected at runtime, with a
# safe fallback to other methods when it cannot be used.
#
# Note that kqueue is broken on most operating systems, so by default it
# won't be used on many platforms, but you can still create your own event
# loop with kqueue backend if you ask specifically for it.
#
# Here is what we know:
#
# NetBSD: partially working in at least 3.1 and later. Yeah! :)
# FreeBSD: broken on at least 6.2-STABLE, spotty in later versions,
# sockets *likely* work, ptys definitely don't.
# OpenBSD: reports indicate that it likely doesn't work
# (similar problems as on FreeBSD).
# OS X: completely, utterly broken on at least <= 10.6.
#
# Enable kqueue backend (y/n)? [n] n

# Similarly to the kqueue backend above, EV can take advantage of the
# solaris 10 event port interface. Support for event ports will be detected
# at runtime, with a safe fallback to other methods when it cannot be used.

#
# EV needs the functions pthread_atfork and clock_gettime. On most systems
# you need some special libraries for this (such as -lrt and -lpthread). You
# can specify additional libraries to provide these calls (and any other
# required by EV) now, or accept the default.
#
# On GNU/Linux systems, EV uses the LSB 3.1 __register_atfork function
# to avoid the dependency on libpthread, and directly uses the clock_gettime
# syscall to avoid a dependency on librt.
#
# Extra libraries for pthread_atfork and clock_gettime? [ ]

#
#
# A backend of a different kind is the Linux inotify(7) interface, which can
# be used to speed up (and reduce resource consumption) of stat watchers. If
# you have the include file and libc support for it, it is usually a good
# idea to enable it, as kernel availability is detected at runtime.
#

#
#
# Another useful bit of functionality is the Linux eventfd, which is useful
# for faster signal handling (don't care) and intra-thread communications
# (more relevant). Kernel support for this will be probed at runtime, but
# your libc must contain the necessary wrapper. Glibc 2.7 and later should
# have this wrapper.

# Very rarely, people want to tweak EV even more, e.g. to exclude
# or include certain watcher types or backends. This can be done by adding
# extra -D options here, or via the EV_EXTRA_DEFS environment variable.
#
# For example, if you run into compile problems because of missing memory
# fences (or you just want extra performance), you can tell EV to not support
# smp and threads via -DEV_NO_THREADS.
#
# Normal persons just press enter.
#
# Any extra -D options? []
