md5sum and dak

[Daniele Favara]

hi,

Would it be a good idea to start including some "def" from dak ?

ex: daklib.utils.poolify, daklib.utils.extract_component_from_section

and a  get_md5sum :

def _get_md5sum(path):
     import md5
     BLOCKSIZE = 16384
     digest = md5.md5()
     f = open(path)
     data = f.read(BLOCKSIZE)
     while data:
         digest.update(data)
         data = f.read(BLOCKSIZE)
     return str(digest.hexdigest())

====================================================

def poolify (source, component):
     if component:
	component += '/'
     # FIXME: this is nasty
     component = component.lower().replace("non-us/", "non-US/")
     if source[:3] == "lib":
	return component + source[:4] + '/' + source + '/'
     else:
	return component + source[:1] + '/' + source + '/'

def extract_component_from_section(section):
     component = ""

     if section.find('/') != -1:
         component = section.split('/')[0]
     if component.lower() == "non-us" and section.find('/') != -1:
         s = component + '/' + section.split('/')[1]
         if Cnf.has_key("Component::%s" % s): # Avoid e.g. non-US/libs
             component = s

     if section.lower() == "non-us":
         component = "non-US/main"

     # non-US prefix is case insensitive
     if component.lower()[:6] == "non-us":
         component = "non-US"+component[6:]

     # Expand default component
     if component == "":
         if Cnf.has_key("Component::%s" % section):
             component = section
         else:
             component = "main"
     elif component == "non-US":
         component = "non-US/main"

     return (section, component)
