   3 ## Script to build and test the latest python from svn.  It basically
   4 ## does this:
   5 ##   svn up ; ./configure ; make ; make test ; make install ; cd Doc ; make
   6 ##
   7 ## Logs are kept and rsync'ed to the host.  If there are test failure(s),
   8 ## information about the failure(s) is mailed.
   9 ##
  10 ## This script is run on the PSF's machine as user neal via crontab.
  11 ##
  12 ## Yes, this script would probably be easier in python, but then
  13 ## there's a bootstrap problem.  What if Python doesn't build?
  14 ##
  15 ## This script should be fairly clean Bourne shell, ie not too many
  16 ## bash-isms.  We should try to keep it portable to other Unixes.
  17 ## Even though it will probably only run on Linux.  I'm sure there are
  18 ## several GNU-isms currently (date +%s and readlink).
  19 ##
  20 ## Perhaps this script should be broken up into 2 (or more) components.
  21 ## Building doc is orthogonal to the rest of the python build/test.
  22 ##
  23
  24 ## FIXME: we should detect test hangs (eg, if they take more than 45 minutes)
  25
  26 ## FIXME: we should run valgrind
  27 ## FIXME: we should run code coverage
  28
  29 ## Utilities invoked in this script include:
  30 ##    basename, date, dirname, expr, grep, readlink, uname
  31 ##    cksum, make, mutt, rsync, svn
