  13 # This is the "Release" of the Libevent ABI.  It takes precedence over
  14 # the VERSION_INFO, so that two versions of Libevent with the same
  15 # "Release" are never binary-compatible.
  16 #
  17 # This number incremented once for the 2.0 release candidate, and
  18 # will increment for each series until we revise our interfaces enough
  19 # that we can seriously expect ABI compatibility between series.

  23 # This is the version info for the libevent binary API.  It has three
  24 # numbers:
  25 #   Current  -- the number of the binary API that we're implementing
  26 #   Revision -- which iteration of the implementation of the binary
  27 #               API are we supplying?
  28 #   Age      -- How many previous binary API versions do we also
  29 #               support?
  30 #
  31 # To increment a VERSION_INFO (current:revision:age):
  32 #    If the ABI didn't change:
  33 #        Return (current:revision+1:age)
  34 #    If the ABI changed, but it's backward-compatible:
  35 #        Return (current+1:0:age+1)
  36 #    If the ABI changed and it isn't backward-compatible:
  37 #        Return (current+1:0:0)
  38 #
  39 # Once an RC is out, DO NOT MAKE ANY ABI-BREAKING CHANGES IN THAT SERIES
  40 # UNLESS YOU REALLY REALLY HAVE TO.

  71 # ABI version history for this package effectively restarts every time
  72 # we change RELEASE.  Version 1.4.x had RELEASE of 1.4.
  73 #
  74 # Ideally, we would not be using RELEASE at all; instead we could just
  75 # use the VERSION_INFO field to label our backward-incompatible ABI
  76 # changes, and those would be few and far between.  Unfortunately,
  77 # Libevent still exposes far too many volatile structures in its
  78 # headers, so we pretty much have to assume that most development
  79 # series will break ABI compatibility.  For now, it's simplest just to
  80 # keep incrementing the RELEASE between series and resetting VERSION_INFO.
  81 #
  82 # Eventually, when we get to the point where the structures in the
  83 # headers are all non-changing (or not there at all!), we can shift to
  84 # a more normal worldview where backward-incompatible ABI changes are
  85 # nice and rare.  For the next couple of years, though, 'struct event'
  86 # is user-visible, and so we can pretty much guarantee that release
  87 # series won't be binary-compatible.
