  Message : Add wepoll support to light up the epoll backend on Windows libevent is lacking a scalable backend on Windows. Let's leverage the wepoll library until Windows comes up with an epoll/kqueue compete user mode API. - All regress tests pass for standard wepoll - These 2 tests fail intermittently for changelist wepoll, so disabling changelist wepoll for now http/cancel_inactive_server http/stream_in - verify target on Windows runs tests for both wepoll and win32 backends - wepoll backend preferred over win32 backend - wepoll version 1.5.6 v2: cleaner backend abstraction. Disallow wepoll on MinGW/Cygwin. v3: Add wepoll.h to dist v4: Make sure wepoll source files are excluded from cygwin/mingw builds v5: Keep win32 as default backend on windows. v6: Include wepoll in mingw builds. Verified that regress tests pass w/ WEPOLL backend. v7: Enable wepoll on mingw when building with cmake v8: Add wepoll testrunner for autotools test target

  # This is the "Release" of the Libevent ABI.  It takes precedence over
  # the VERSION_INFO, so that two versions of Libevent with the same
  # "Release" are never binary-compatible.
  #
  # This number incremented once for the 2.0 release candidate, and
  # will increment for each series until we revise our interfaces enough
  # that we can seriously expect ABI compatibility between series.

  # This is the version info for the libevent binary API.  It has three
  # numbers:
  #   Current  -- the number of the binary API that we're implementing
  #   Revision -- which iteration of the implementation of the binary
  #               API are we supplying?
  #   Age      -- How many previous binary API versions do we also
  #               support?
  #
  # To increment a VERSION_INFO (current:revision:age):
  #    If the ABI didn't change:
  #        Return (current:revision+1:age)
  #    If the ABI changed, but it's backward-compatible:
  #        Return (current+1:0:age+1)
  #    If the ABI changed and it isn't backward-compatible:
  #        Return (current+1:0:0)
  #
  # Once an RC is out, DO NOT MAKE ANY ABI-BREAKING CHANGES IN THAT SERIES
  # UNLESS YOU REALLY REALLY HAVE TO.

  # For Libevent 2.2:

  # ABI version history for this package effectively restarts every time
  # we change RELEASE.  Version 1.4.x had RELEASE of 1.4.
  #
  # Ideally, we would not be using RELEASE at all; instead we could just
  # use the VERSION_INFO field to label our backward-incompatible ABI
  # changes, and those would be few and far between.  Unfortunately,
  # Libevent still exposes far too many volatile structures in its
  # headers, so we pretty much have to assume that most development
  # series will break ABI compatibility.  For now, it's simplest just to
  # keep incrementing the RELEASE between series and resetting VERSION_INFO.
  #
  # Eventually, when we get to the point where the structures in the
  # headers are all non-changing (or not there at all!), we can shift to
  # a more normal worldview where backward-incompatible ABI changes are
  # nice and rare.  For the next couple of years, though, 'struct event'
  # is user-visible, and so we can pretty much guarantee that release
  # series won't be binary-compatible.
