From: Cyrill Gorcunov <gorcunov@gmail.com> To: tml <tarantool-patches@dev.tarantool.org> Subject: [Tarantool-patches] [PATCH v2 6/7] popen: handle setsid os specifics Date: Fri, 6 Mar 2020 17:30:47 +0300 [thread overview] Message-ID: <20200306143047.GA27301@uranus> (raw) In-Reply-To: <20200302201227.31785-7-gorcunov@gmail.com> Due to os specifics we can't call setsid after vfork on macos (vfork is not longer a part of posix btw). Thus lets simply ignore it. If there gonna be a strong need to drop controlling terminal (we could use ioctl) or setup new group we will enhance it. But only if really needed.
