#!/bin/sh

## Script to build and test the latest python from svn.  It basically
## does this:
##   svn up ; ./configure ; make ; make test ; make install ; cd Doc ; make
##
## Logs are kept and rsync'ed to the host.  If there are test failure(s),
## information about the failure(s) is mailed.
##
## This script is run on the PSF's machine as user neal via crontab.
##
## Yes, this script would probably be easier in python, but then
## there's a bootstrap problem.  What if Python doesn't build?
##
## This script should be fairly clean Bourne shell, ie not too many
## bash-isms.  We should try to keep it portable to other Unixes.
## Even though it will probably only run on Linux.  I'm sure there are
## several GNU-isms currently (date +%s and readlink).
##
## Perhaps this script should be broken up into 2 (or more) components.
## Building doc is orthogonal to the rest of the python build/test.
##

## FIXME: we should detect test hangs (eg, if they take more than 45 minutes)

## FIXME: we should run valgrind
## FIXME: we should run code coverage

## Utilities invoked in this script include:
##    basename, date, dirname, expr, grep, readlink, uname
##    cksum, make, mutt, rsync, svn

## remember where did we started from
