PIPE_MAX_SIZE is much larger than the effictive size of a pipe on Linux. It's defined as: # A constant likely larger than the underlying OS pipe buffer size, to # make writes blocking. # Windows limit seems to be around 512 B, and many Unix kernels have a # 64 KiB pipe buffer size or 16 * PAGE_SIZE: take a few megs to be sure. # (see issue #17835 for a discussion of this number). PIPE_MAX_SIZE = 4 * 1024 * 1024 + 1 I don't think that PIPE_MAX_SIZE+1 makes a difference here. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue23680> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
