cleanupAbsPath(path)

source code  
take ~taw/../some/path/$MOUNT_POINT/blah and make it sensible.

Path returned is absolute.
NOTE: python 2.2 fixes a number of bugs with this and eliminates
      the need for os.path.expanduser

cleanupNormPath(path, dotYN=0)

source code  
take ~taw/../some/path/$MOUNT_POINT/blah and make it sensible.

Returned path may be relative.
NOTE: python 2.2 fixes a number of bugs with this and eliminates
      the need for os.path.expanduser

rotateFile(filepath, depth=5, suffix='.', verbosity=0)

source code  
backup/rotate a file
depth (-1==no limit) refers to num. of backups (rotations) to keep.

Behavior:
  (1)
    x.txt (current)
    x.txt.1 (old)
    x.txt.2 (older)
    x.txt.3 (oldest)
  (2)
    all file stats preserved. Doesn't blow away original file.
  (3)
    if x.txt and x.txt.1 are identical (size or checksum), None is
    returned

rhn_popen(cmd, progressCallback=None, bufferSize=16384, outputLog=None)

source code 

popen-like function, that accepts execvp-style arguments too (i.e. an array of params, thus making shell escaping unnecessary)

cmd can be either a string (like "ls -l /dev"), or an array of arguments ["ls", "-l", "/dev"]

Returns the command's error code, a stream with stdout's contents and a stream with stderr's contents

progressCallback --> progress bar twiddler outputLog --> optional log file file object write method

createPath(path, user=None, group=None, chmod=493)

source code 

advanced makedirs

Will create the path if necessary. Will chmod, and chown that path properly. Defaults for user/group to the apache user

Uses the above makedirs() function.
