[New-bugs-announce] [issue17169] Restore errno in tempfile exceptions

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

Before 3.3 if not able to create the name of the temporary file then an OSError with meaninful errno (ENOENT or EEXIST) was raised. Now subclass of OSError raised with errno=None. This is an incompatible change because old user code can catch OSError exception and then test its errno.

Here is a patch which restores errno attribute in these exceptions.
