Andrew Dalke <[EMAIL PROTECTED]> added the comment: I'm still undecided on if this is a bug or not. The problem occurs even when I'm not reading "data from a file of an unknown size." My example causes a MemoryError on my machine even though the file I'm reading contains 0 bytes.
The problem is Python's implementation is "alloc the requested bytes and truncate if needed" vs what I expected "read chunks at a time up to the requested number of bytes." There's nothing in the documentation which states the implementation, although "Note that this method may call the underlying C function fread more than once in an effort to acquire as close to size bytes as possible." leans slightly towards my interpretation. I looked a little for real-world cases that could cause a denial-of- service attack but didn't find one. If there is a problem, it will occur very rarely. Go ahead an mark it as "will not fix" or something similar. I don't think the change in the code is justifiable. _______________________________________ Python tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue3531> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
