#     CHECKSUM.PY -- CHECKSUM THE P4DTI SOURCES TO DETECT CHANGES
#
#             Gareth Rees, Ravenbrook Limited, 2001-03-05.
#
#
# 1. INTRODUCTION
#
# This Python script prints an MD5 checksum of the P4DTI sources.  The
# purpose is to allow Perforce support to easily determine if an
# organization has altered the P4DTI sources (and so are running an
# unsupported configuration) by asking the customer to run checksum.py
# and comparing the result to the checksum for the release.  This fixes
# job000252.
#
# The intended readership is project developers.
#
# This document is not confidential.


import md5

# We produced this by running p4 files "*.py" and removing (a) deleted
# files and (b) files that people are supposed to change, namely
# config.py and example_trigger.py.

# Python 1.5.2 doesn't have md5.hexdigest(), so we do it ourselves:
def hexify(s):
    result = ""
    for c in s:
       result = result + ("%02x" % ord(c))
    return result

if __name__ == '__main__':
    cs = md5.new()
    for file in files:
        cs.update(open(file, 'r').read())
    print hexify(cs.digest())
