[PythonCE] Current Directory emulation (fix)

[Telion]

I pasted wrong one in the earlier post.
Please try this one instead.

### os.getcwd, os.chdir emulation + os.listdir fix ###
import os
os.cwd = "\\"
def __getcwd(): return os.cwd
os.getcwd =  __getcwd
def __fullpath(p): 
	if not p or type(p) != str:
		raise OSError, "Invalid path"
	if not p[0] in "/\\":
		p = os.path.join(os.cwd,p)
	p = p.replace('/','\\')
	pl = p.split('\\')
	#print pl
	i =0
	while 1:
		if i >= len(pl):
			break
		#print i, pl[i]
		if pl[i] =='..':
			try:
				pl.pop(i)
				pl.pop(i-1)
			except:
				raise OSError, "Invalid path"
			i -= 1
			if i < 0:
				raise OSError, "Invalid path"
		elif not pl[i]:
			pl.pop(i)
		else:
			i += 1
	return "\\"+"\\".join(pl)

def __chdir(p):
	fullpath = __fullpath(p)
	if os.path.isdir(fullpath):
		os.cwd = fullpath
	else:
		raise OSError, "Invalid path"

os.chdir = __chdir

# os.listdir may fails when "\\storage card\\../" is the given path
# It does not fail when "\\wndows\\..\\" or "/Program files/../"
# Probably something related with CF or memory card.
# So, give the aboslute path, instead.
os.oldlistdir = os.listdir

def __listdirfix(p): 
	if p != '':
		p = __fullpath(p)
	#print p
	if p == "\\":
		p = ''
	return os.oldlistdir(p)

os.listdir = __listdirfix


#### END OF CE FIX ###
