getowner() etc. work only with file based streams and not with memory buffers. getsize() works with every concrete class in io.py > - in general, streams (which really is the interface for file-like > objects) don't have the notion of "size"; only some do. I understand that getsize() doesn't make sense for e.g. a socket based stream. However the implementation of getsize() works with memory buffers and file descriptors > - what is the purpose of the f.tell fragment? ie. why could that work > when fstat doesn't? The tell(), seek(0,2) is a generic fall back for io instances that aren't based on a file descriptor. It's required for BytesIO and StringIO. However I could come up with an implementation for BytesIO that queries the buffer directly. __________________________________ Tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue1351> __________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
