Description of problem:
$ touch ~/foo
touch: cannot touch '/home/fedora/foo': Read-only file system
Python 3.9.0b3 (default, Jun 10 2020, 00:00:00)
[GCC 10.1.1 20200507 (Red Hat 10.1.1-1)] on linux
Type "help", "copyright", "credits" or "license" for more information.
Error in atexit._run_exitfuncs:
Traceback (most recent call last):
File "/usr/lib64/python3.9/site.py", line 462, in write_history
OSError: [Errno 30] Read-only file system
Looking at /usr/lib64/python3.9/site.py, it already silently skips
PermissionError. It should handle EROFS the same.
Version-Release number of selected component (if applicable):
Do I assume correctly that this is not a regression of 3.9?
Would you please report this upstream?
See also https://bugs.python.org/issue15833
I proposed a fix upstream: https://github.com/python/cpython/pull/21279 If it's merged, it will be part of the next Python 3.9 release.
I don't think that we need to backport it earlier in Fedora. We can wait until the Fedora package will be rebased to the newer Python 3.9 version. So I close the issue as UPSTREAM.
Thanks for your bug report Zbigniew Jędrzejewski-Szmek!
In the meanwhile, you can safely ignore the error. You may be able to workaround the issue by overriding the HOME directory by setting HOME environment variable: use a temporary directory which can be modified.
