[Tarantool-patches] [PATCH v3 0/5] popen: Add ability to run external process

[Cyrill Gorcunov <gorcunov@gmail.com>]

In this series we provide a way to execute external binaries
from inside of Lua scripts, control children process and
communicate with their stdin/out/err streams.

In v3 I addressed a problem of soft termination of
a child process and updated changelog for Lua interface.

Probably the best way to start read this series is
the last patch where real examples of usage are
present.

  lua/fio: Add lbox_fio_push_error as a separate helper
