Jan Lachnitt added the comment:
Here is a part of my code (with some comments added):
for struct in ini_structures:
dirname = wrkdir+os.sep+struct.name
if not os.path.isdir(dirname): # This works fine. If the directory
doesn't exist,...
try:
os.mkdir(dirname) # ... it is created here.
except OSError:
raise AutoLEEDError('Cannot create directory "'+dirname+'".')
dirname += os.sep+'bulk' # This defines a subdirectory.
if not os.path.isdir(dirname): ## Though it doesn't exist,
os.path.isdir returns True,...
try:
os.mkdir(dirname) # ... so it is not created here.
except OSError:
raise AutoLEEDError('Cannot create directory "'+dirname+'".')
fn = dirname+os.sep+'cluster.i' # This defines a filename.
print('Writing file "'+fn+'"...')
straos = struct.write_bulk_cluster(fn,at_rad) # Here it fails (cannot
write to file).
According to Victor's post, I have inserted these lines before the line marked
## (and added necessary imports):
print('dirname =', dirname)
print('os.path.isdir(dirname) =', os.path.isdir(dirname))
print('nt._isdir(dirname) =', nt._isdir(dirname))
print('stat.S_ISDIR(os.stat(dirname).st_mode) =',
stat.S_ISDIR(os.stat(dirname).st_mode))
print(ascii(dirname.encode("unicode_internal")))
print(ascii(dirname.encode("utf-8")))
Here is the output of these lines (that directory really does not exist but its
parent directory does):
dirname = D:\Bug reports\Python\AutoLEED\default\sub-fcc\bulk
os.path.isdir(dirname) = True
nt._isdir(dirname) = True
stat.S_ISDIR(os.stat(dirname).st_mode) = True
b'D\x00:\x00\\\x00B\x00u\x00g\x00

Yeah, the result of ascii(dirname.encode("unicode_internal")) seems to be wrong
(at the end).
