New submission from STINNER Victor <victor.stin...@haypocalc.com>: TextIOWrapper.readline() is much faster (eg. 72 ms vs 95 ms) than BufferedReader.readline(). It's because BufferedReader always acquires the file lock, whereas TextIOWrapper only acquires the file lock when the buffer is empty.
I would like a BufferedReader.readline() as fast as TextIOWrapper.readline(), or faster! Why BufferedReader's attributes are protected by a lock whereas TextIOWrapper's attributes are not? Does it mean that TextIOWrapper may crash if two threads calls readline() (or different methods) at the "same time"? How does Python 2.x and 3.0 fix this issue? ---------- components: Library (Lib) messages: 83724 nosy: haypo, pitrou severity: normal status: open title: io-c: TextIOWrapper is faster than BufferedReader but not protected by a lock versions: Python 3.1 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue5502> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
