[tarantool-patches] [PATCH v4 0/4] Syslog destination

[Olga Arkhangelskaia <arkholga@tarantool.org>]

This series adds support of configurable destionation for syslog.
The option is called server. Possible options are ip4 and unix socket:
syslog:server=unix:/path/to/socket,identity=myinstance
syslog:server=ip4:port,identity=tarantool_myinstance

If server option is not set, but syslog is used in log configuration - 
default sockets for syslogd are used: /dev/log or /var/run/syslog.

Olga Arkhangelskaia (4):
  Configurable syslog destination
  box-tap: test valid log configuration
  box-tap: syslog destination test unix socket
  box-tap:syslog remote destination test
