#!/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 webhost. If there are test failure(s),
## information about the failure(s) is mailed.
##
## The user must be a member of the webmaster group locally and on webhost.
##
## 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
