   4 Subject: [PATCH 05/10] MINOR: config: extend the default max hostname length
   5  to 64 and beyond
   6
   7 Some users reported that the default max hostname length of 32 is too
   8 short in some environments. This patch does two things :
   9
  10   - it relies on the system's max hostname length as found in MAXHOSTNAMELEN
  11     if it is set. This is the most logical thing to do as the system libs
  12     generally present the appropriate value supported by the system. This
  13     value is 64 on Linux and 256 on Solaris, to give a few examples.
  14
  15   - otherwise it defaults to 64
  16
  17 It is still possible to override this value by defining MAX_HOSTNAME_LEN at
  18 build time. After some observation time, this patch may be backported to
  19 1.5 if it does not cause any build issue, as it is harmless and may help
  20 some users.
