so i am trying to add md5 checksum calc to my file copy stuff, to make
sure the source and dest. are same file.
i implemented it fine with the single file copy part. something like :
for files in sourcepath:
f1=file(files ,'rb')
try:
shutil.copy2(files,
os.path.join(destpath,os.path.basename(files)))
except:
print "error file"
f2=file(os.path.join(destpath,os.path.basename(files)), 'rb')
truth = md5.new(f1.read()).digest() ==
md5.new(f2.read()).digest()
if truth == 0:
print "file copy error"
this worked swimmingly. i moved on to my backupall function, something
like
for (path, dirs, files) in os.walk(source):
#os.walk drills down thru all the folders of source
for fname in dirs:
currentdir = destination+leftover
try:
os.mkdir(os.path.join(currentdir,fname),0755)
except:
print "error folder"
for fname in files:
leftover = path.replace(source, '')
currentdir = destination+leftover
f1=file(files ,'rb')
try:
shutil.copy2(os.path.join(path,fname),
os.path.join(currentdir,fname))
f2 = file(os.path.join(currentdir,fname,files))
except:
print "error file"
truth = md5.new(f1.read()).digest() ==
md5.new(f2.read()).digest()
if truth == 0:
print "file copy error"
but here, "fname" is a list, not a single file.i didn't really want to
spend a lot of time on the md5 part. thought it would be an easy add-
on. i don't really want to write the file names out to a list and
parse through them one a time doing the calc, but it sounds like i
will have to do something like that.
