New submission from Geoff Alexander <[email protected]>:
I have the following code:
```
def handle_empty_directories(dir):
if os.path.exists(dir):
shouter.shout("%s exists" % dir)
else:
shouter.shout("%s doesn't exists" % dir)
entries = os.listdir(dir)
if entries == []:
open(os.path.join(dir, Commiter.hed_file), "w").close()
else:
if (len(entries) > 1) and (Commiter.hed_file in entries):
os.remove(os.path.join(dir, Commiter.hed_file))
for entry in entries:
if entry not in Commiter.hed_ignore:
full_entry = os.path.join(dir, entry)
if (os.path.isdir(full_entry)):
Commiter.handle_empty_directories(full_entry)
```
Occasionally, the call to os.listdir(dir) fails with FileNotFoundError even
though the os.path.exists(dir) call says that exists:
```
08:57:56 -
C:\r2g-wd\sport-6.0.5\SBS\SBS\Light\bin\com\ibm\ArtifactTechnology\ABS\ArtifactBroker
exists

I've also seen a similar FileNoteFound on the
```
open(os.path.join(dir, Commiter.hed_file), "w").close()
```
line when os.path.exists(dir) says that the directory exists.
How can this happen? I'm running Python 3.7.2 64-bit on Windows 10.
