Entirely mechanical, produced by `ruff check --fix --select F401,F541,E713`
and reviewed rather than taken on faith: deleting an import is only safe if
nothing imports it for its side effects or re-exports it. None of the 19
removed names is referenced anywhere in its file, none appears in any string
literal, and none of the touched files uses eval, exec, globals() or
__import__, so there is no dynamic lookup that could reach them.
chown() clears the setuid bit of a file on Linux (and its setgid bit, if
the file is group-executable), even when run by root and even when the
owner/group are unchanged. Since the owner/group chown ran after the
permissions chmod, any syncfiles entry combining owner=/group= with a
setuid/setgid permissions= value silently lost the special bits.
get_syncresult() caught the sync task's exception, logged a repr server
side and returned 200 OK with a null body. The node then called
.get('options') on that null resulted in:
c1: 'NoneType' object has no attribute 'get'
and syncfileclient still exited 0 as if syncing had succeeded.
Return the error to the requestor as a 500 with an error payload. On
the node, unwrap the body that grab_url_with_status raises for a
non-success status, print it once and exit non-zero. Only a failure the
server deliberately reported for this sync is terminal. Anything else,
such as a dropped connection, is re-raised so the existing retry loop
handles it as before. The same case now reports
c1: Error performing syncfiles: Syncing failed due to unreadable files: /etc/dangling.conf
c1: 'syncfileclient' exited with code 1
