Branch: refs/heads/1.6.0 Home: https://github.com/tribe29/checkmk Commit: 1a2928486c805961b1302464038dd140946d2fea https://github.com/tribe29/checkmk/commit/1a2928486c805961b1302464038dd1409… Author: Mathias Laurin <mathias.laurin(a)tribe29.com> Date: 2020-02-05 (Wed, 05 Feb 2020) Changed paths: M livestatus/src/Makefile.am M livestatus/src/OutputBuffer.cc A livestatus/src/SocketUtils.cc A livestatus/src/SocketUtils.h Log Message: ----------- Make write(2) non-blocking POSIX does not guarantee that `write(2)` does not block after `select(2)` or `poll(2)`. So we set the fd to O_NONBLOCK before writing and handle EAGAIN and EWOULDBLOCK thereafter. Note that `read(2)` is different so that `read(2)` after `select(2)` does not block.
