>>> f = open("/dev/stdout", "w+b") # Or any non-seekable file, pipe, etc
__main__:1: ResourceWarning: unclosed file <_io.FileIO name='/dev/stdout' mode='rb+'>
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
io.UnsupportedOperation: File or stream is not seekable.
It is mainly just the annoyance of the ResourceWarning, so nothing major. I think this was previously identified in Issue 18116, but it looks like that bug was side-stepped by removing an equivalent fdopen() call.
No ResourceWarning happens with an unbuffered file. I haven’t looked at the code but I guess the UnsupportedOperation might only be raised after trying to wrap the open FileIO object in a BufferedWriter object. |
