Fix
FileResponse
doing blocking I/O in the event loopThe call to
os.stat
was run in the executor but the call tois_file()
was not. Additionally this resulted in two syscalls tostat
since bothis_file
andstat
will callstat
under the hood. The code has been refactored to ensure there is only onestat
syscall and it happens in the executorAre there changes in behavior for the user?
No
