When running ComfyUI in API mode on Windows, print() statements from
custom nodes can crash with "OSError: [Errno 22] Invalid argument"
during flush. This occurs because piped/redirected stdout streams on
Windows may fail to flush even after successful writes.
This fix catches OSError with errno 22 (EINVAL) specifically in
LogInterceptor.flush(), allowing the flush callbacks to still execute.
The error is safe to ignore since write() already succeeded.
Fixes#11367
* nit
* Add option to log non-error output to stdout
- No change to default behaviour
- Adds CLI argument: --log-stdout
- With this arg present, any logging of a level below logging.ERROR will be sent to stdout instead of stderr
* Add /logs/raw and /logs/subscribe for getting logs on frontend
Hijacks stderr/stdout to send all output data to the client on flush
* Use existing send sync method
* Fix get_logs should return string
* Fix bug
* pass no server
* fix tests
* Fix output flush on linux
* Add route for getting output logs
* Include ComfyUI version
* Move to own function
* Changed to memory logger
* Unify logger setup logic
* Fix get version git fallback
