Summary:
Fixes #2010.
This patch is primarily directed at Unices. On Windows, the underlying
problem should not be an issue, because the default temporary directory
seems to be user-scoped (e.g.,
C:\Users\wchargin\AppData\Local\Temp
).Test Plan:
Unit tests added. Before this change, the first test has an assertion
error (
'0o755' != '0o777'
) and the second test has an I/O error tryingto write to a non-writable directory. After this change, all tests pass.
Tested only on Linux.
