That would be surprising. An easy way to find this out would be to remove the ifdef: 352 #ifdef O_APPEND 353 if (append) 354 flags |= O_APPEND; 355 #endif >> Whereas the behavior of O_APPEND causes an automatic seek to the end >> before any write(). > > True, but IIRC some systems seek on open() and some systems seek just before > write(). POSIX makes it clear that only the later behavior is legal: O_APPENDIf set, the file offset shall be set to the end of the file prior to each write. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue18876> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
