My environment:
Windows as host OS, VirtualBox VM, Linux as guest OS
When temporary directory is a directory which mounted from the host OS, a
"OSError: [Errno 26] Text file busy" exception is thrown.
Test file:
import tempfile
with tempfile.TemporaryFile(dir="/tmp") as tf:
tf.write("testing testing testing\n".encode('utf-8'))
print("Temp file: worked")
"/tmp" directory - is a shared folder (vboxsf)
Result:
root@0e87f2561643:/# python /etc/odoo/tempfile-test.py
Traceback (most recent call last):
File "/etc/odoo/tempfile-test.py", line 3, in <module>
with tempfile.TemporaryFile(dir="/tmp") as tf:
File "/usr/lib/python2.7/tempfile.py", line 513, in TemporaryFile
_os.unlink(name)
OSError: [Errno 26] Text file busy: '/tmp/tmpsl0JQI'
