[New-bugs-announce] [issue31611] Tests failures using -u largefile when the disk is full

[STINNER Victor]

New submission from STINNER Victor <victor.stinner at gmail.com>:

I ran the Python test suite on Windows on a freshly installed Python 3.7a1 and I got errors: bpo-31606.

I created a separated issue for tests failing because my disk has low free space.


On my Windows VM, I have a single 40 GB disk with 1.36 GB free.

C:\Users\haypo\AppData\Local\Programs\Python\Python37>python -m test -v -u all test_largefile

======================================================================
ERROR: test_truncate (test.test_largefile.PyLargeFileTest)

    return os.write(self._fd, b)

(other tests fail with similar message)
