❗ I have followed the Contributing to DVC checklist.
📖 If this PR requires documentation updates, I have created a separate PR (or issue, at least) in dvc.org and linked it here. If the CLI API is changed, I have updated tab completion scripts.
❌ I will check DeepSource, CodeClimate, and other sanity checks below. (We consider them recommendatory and don't expect everything to be addressed. Please fix things that actually improve code or fix bugs.)
Thank you for the contribution - we'll try to review it as soon as possible. 🙏
Will close #3482.
paramiko is loaded lazily, so the paramiko logger is not suppressed in
dvc/logger.py::disable_other_loggers(). This leads to paramiko emitting expected error messages when we hit the max SFTP channel limit, even though it is not an error condition for DVC. The logger should just be suppressed when we load paramiko, since any actual SSH/SFTP errors will be caught and logged as DvcExceptions.
