Summary: md5 sums are different between Solaris and Windows XP SP1
Initial Comment:
The following program produces
different md5 sums under Solaris and Windows XP,
but sums are equal under the same platform.
#!/opt/ASpy23/bin/python
import sys
import md5
import getopt
import os
import re
try:
opts,args = getopt.getopt(sys.argv[1:],'c:f:h')
except getopt.GetoptError,e:
print 'Parsing command line arguments failed. (%s)'
% str(e)
sys.exit(1)
md5file = None
fname = None
for o,a in opts:
if o in '-c':
if fname is not None:
print '-c and -f are mutually exclusive'
sys.exit(1)
md5file = a
if o in '-f':
if md5file is not None:
print '-c and -f are mutually exclusive'
sys.exit(1)
fname = a
if o in '-h':
print 'Usage: md5 filename. (%s)' % str(e)
sys.exit(1)
if md5file is not None and os.path.isfile(md5file):
try:
lines = open(md5file,'r').readlines()
except IOError,e:
print 'Could not read MD5 sum file %s. (%s)' %
(md5file,str(e))
sys.exit(1)
for line in lines:
line = line[:-1]
try:
res = re.compile('MD5[ |\t]+\((.+)\)[
|\t]+?\=[ |\t]+(.+)').findall(line)[0]
except Exception,e:
print 'Could not parse line. (%s)' % str(e)
sys.exit(1)
if os.path.isfile(res[0]):
try:
f = open(res[0],'r')
except IOError,e:
print 'Could not open file %s. (%s)' %
(res[0],str(e))
sys.exit(1)
sum = md5.new()
try:
sum.update(f.read())
except Exception,e:
print 'Could not update MD5 sum. (%s)'
% str(e)
sys.exit(1)
#print sum.hexdigest(),res[1][2:],res[0],line
if sum.hexdigest() == res[1][2:]:
print 'MD5 sum of file %s is OK' % res[0]
else:
print 'MD5 sum of file %s DIFFERS' % res[0]
f.close()
sum = None
sys.exit(0)
sum = md5.new()
try:
f = open(fname,'r')
except IOError,e:
print 'Could not open %s. (%s)' % ( fname,str(e) )
try:
sum.update(f.read())
except Exception,e:
print 'Could not update md5 sum. (%s)' % str(e)
print 'MD5 (%s) = 0x%s' % (fname,sum.hexdigest())
f.close()

You're opening files in text mode, which is likely to return
different file contents on Windows and Unix.
