# Framework for starting test servers.
# Based on the type of server specified, check for port availability, remove
# temporary files, start the server, and verify that the server is running.
# If a server is specified, start it. Otherwise, start all servers for test.
use strict;
use Cwd;
use Cwd 'abs_path';
use Getopt::Long;
# Usage:
# perl start.pl [--noclean] [--restart] [--port port] test [server [options]]
#
# --noclean Do not cleanup files in server directory.
#
# --restart Indicate that the server is being restarted, so get the
# server to append output to an existing log file instead of
# starting a new one.
#
# --port port Specify the default port being used by the server to answer
# queries (default 5300). This script will interrogate the
# server on this port to see if it is running. (Note: for
# "named" nameservers, this can be overridden by the presence
# of the file "named.port" in the server directory containing
# the number of the query port.)
#
# test Name of the test directory.
#
# server Name of the server directory. This will be of the form
# "nsN" or "ansN", where "N" is an integer between 1 and 8.
# If not given, the script will start all the servers in the
# test directory.
#
# options Alternate options for the server.
#
# NOTE: options must be specified with '-- "<option list>"',
# for instance: start.pl . ns1 -- "-c n.conf -d 43"
#
# ALSO NOTE: this variable will be filled with the contents
# of the first non-commented/non-blank line of args in a file
# called "named.args" in an ns*/ subdirectory. Only the FIRST
# non-commented/non-blank line is used (everything else in
# the file is ignored). If "options" is already set, then
# "named.args" is ignored.
