Package: release.debian.org
Severity: normal

Usertags: unblock
X-Debbugs-Cc: python-mitogen@packages.debian.org
Control: affects -1 + src:python-mitogen
Please unblock package python-mitogen
[ Reason ]
This resolves bug 1036018. Apparently ansible has grown the number of
open file handles over time, causing select() to become unusable.
Use poll() instead of select.
python-mitogen development is somewhat sporadic at the moment. We
patched it to support Ansible 6, even though upstream hadn't declared
support, yet. That probably contributed to this bug appearing.
Upstream hasn't picked up this patch, yet. But it's been sitting on
GitHub since early Feb, and resolves the issue.
[ Impact ]
Some users will hit "filedescriptor out of range in select()" errors
when using ansible with miteogen.
[ Tests ]
I've manually tested ansible with mitogen, and it seems to work.
The automated test suite passes.
Some of the GitHub actions tests for this PR failed. But the affected
platforms don't seem relevant to us.
[ Risks ]
Patch is relatively straightforward. Replacing one drop-in class in
place of another.
[ Checklist ]
[x] all changes are documented in the d/changelog
[x] I reviewed all changes and I approve them
[x] attach debdiff against the package in testing
