> We've moved illumos-gate wsdiff python tool from Python 2 to Python 3. I guess that you're talking about https://github.com/illumos/illumos-gate/blob/master/usr/src/tools/scripts/wsdiff.py This project is part of illumos: "An open-source Unix operating system". It's a fork of Solaris. Python does not officially support Solaris not Illumos. If someone provides a patch, we can review it. But I'm not aware of anyone working actively on supporting Illumos. In the meanwhile, there are two workarounds: * Use subprocess.Popen(close_fds=False): it should be safe since PEP 446 has been implemented in Python 3.4... except for C extension modules and C libraries which don't implement it. * Reduce the maximum number of file descriptors. On Linux and FreeBSD (if fdescfs kernel module is loaded and mounted), Python 3 iterates on /proc/self/fd/. On FreeBSD, the closefrom() syscall can be used: PR 19697. But I'm not aware of any more efficient solution for Illumos. Since the latest comment of the original poster was last August, I close the issue. ---------- resolution: -> out of date stage: -> resolved status: open -> closed title: subprocess.Popen() is extremely slow -> subprocess.Popen() is extremely slow (with close_fds=True which is the default) on Illumos _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue37790> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
