[Tarantool-patches] [PATCH v2 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 v2 I tried to stabilize api a bit still i don't like
current Lua api with a passion, thus please take a look
if we can improve here something. I'm far from being
Lua code profi so help would be really appreciated.

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

All patches are sitting in branch gorcunov/gh-4031-popen-2

Cyrill Gorcunov (5):
  popen: Introduce a backend engine
  lua/fio: Add lbox_fio_push_error as a separate helper
  popen/fio: Merge popen engine into fio internal module
  popen/fio: Add ability to run external programs
  test: Add app/popen test
