gipc 0.5.0 released

I just released gipc 0.5.0. It contains a backwards-incompatible change: the SIGPIPE signal action is not automatically reset to the default action anymore in child processes. This will hopefully satisfy developers expecting the SIGPIPE signal to be ignored, resulting in a proper Python exception when attempting to write to a pipe that has been closed on the read end (if interested, you can follow the related discussion here). Furthermore, this release improves the performance when sending large messages through gipc pipes on Linux. This release also introduces workarounds for two corner case issues present in Mac OS X and FreeBSD.

This is the full changelog:

  • Improve large message throughput on Linux (see issue #13).
  • Work around read(2) system call flaw on Mac OS X (see issue #13).
  • Work around signal.NSIG-related problem on FreeBSD (see issue #10).
  • Do not alter SIGPIPE action during child bootstrap (breaking change, see issue #12).

Thanks to Dustin Oprea, bra, John Ricklefs, Heungsub Lee, Miguel Turner, and Alex Besogonov for contributing. As usual, the release is available via PyPI (https://pypi.python.org/pypi/gipc). The documentation and further detail are available at http://gehrcke.de/gipc.
