[issue24666] Buffered I/O does not take file position into account when reading blocks
New submission from Eric Pruitt: When buffering data from a file, the buffered I/O does not take into account the current file descriptor position. In the following example, I open a file and seek forward 1,000 bytes: f = open(test-file, rb) f.seek(1000) 1000 f.readline() The filesystem on which test-file resides has a block size of 4,096 bytes, so on the backend, I would expect Python to read 3,096 bytes so the next read will be aligned with the filesystem blocks. What actually happens is that Python reads a 4,096 bytes. This is the output from an strace attached to the interpreter above: Process 16543 attached lseek(4, 0, SEEK_CUR) = 0 lseek(4, 1000, SEEK_SET)= 1000 read(4, \000\000\000\000\000\000\000\000\000\000..., 4096) = 4096 -- components: IO messages: 246931 nosy: ericpruitt priority: normal severity: normal status: open title: Buffered I/O does not take file position into account when reading blocks type: behavior versions: Python 2.7, Python 3.2, Python 3.3, Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24666 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

As for the other criticisms, I'm sure there are plenty of things that need to be improved upon; I was not a very experienced when I started the project. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue1191964 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue10634] Windows timezone changes not reflected by time.localtime
New submission from Eric Pruitt eric.pru...@gmail.com: If the current time zone changes on Windows, time.localtime will continue to return results that reflect the time zone the system used when the module was imported. My current work around is to use GetLocalTime from kernel32 with ctypes. Windows does not have a tzset() equivalent as it does in Linux, but it seems like modifying time.localtime to use GetLocalTime on Windows systems could make up for this shortcoming. -- components: Windows messages: 123442 nosy: eric.pruitt priority: normal severity: normal status: open title: Windows timezone changes not reflected by time.localtime type: behavior versions: Python 2.5, Python 2.6 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10634 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
