SF patch #462296: Add attributes to os.stat results; by Nick Mathewson.
This is a big one, touching lots of files. Some of the platforms aren't tested yet. Briefly, this changes the return value of the os/posix functions stat(), fstat(), statvfs(), fstatvfs(), and the time functions localtime(), gmtime(), and strptime() from tuples into pseudo-sequences. When accessed as a sequence, they behave exactly as before. But they also have attributes like st_mtime or tm_year. The stat return value, moreover, has a few platform-specific attributes that are not available through the sequence interface (because everybody expects the sequence to have a fixed length, these couldn't be added there). If your platform's struct stat doesn't define st_blksize, st_blocks or st_rdev, they won't be accessible from Python either. (Still missing is a documentation update.)
