# nextpart*() - functions for reading files incrementally
#
# These functions aim to facilitate looking for (or waiting for)
# messages which may be logged more than once throughout the lifetime of
# a given named instance by outputting just the part of the file which
# has been appended since the last time we read it.
#
# Calling some of these functions causes temporary *.prev files to be
# created that need to be cleaned up manually (usually by a given system
# test's clean.sh script).
#
# Note that unlike other nextpart*() functions, nextpartread() is not
# meant to be directly used in system tests; its sole purpose is to
# reduce code duplication below.
#
# A quick usage example:
#
#     $ echo line1 > named.log
#     $ echo line2 >> named.log
#     $ nextpart named.log
#     line1
#     line2
#     $ echo line3 >> named.log
#     $ nextpart named.log
#     line3
#     $ nextpart named.log
#     $ echo line4 >> named.log
#     $ nextpartpeek named.log
#     line4
#     $ nextpartpeek named.log
#     line4
#     $ nextpartreset named.log
#     $ nextpartpeek named.log
#     line1
#     line2
#     line3
#     line4
#     $ nextpart named.log
#     line1
#     line2
#     line3
#     line4
#     $ nextpart named.log
#     $

# nextpartreset: reset the marker used by nextpart() and nextpartpeek()
# so that it points to the start of the given file
nextpartreset() {
    echo "0" > $1.prev
}

# nextpartread: read everything that's been appended to a file since the
# last time 'nextpart' was called and print it to stdout, print the
# total number of lines read from that file so far to stderr
nextpartread() {
    [ -f $1.prev ] || nextpartreset $1
    prev=`cat $1.prev`
    awk "NR > $prev "'{ print }
         END          { print NR > "/dev/stderr" }' $1
}

# nextpart: read everything that's been appended to a file since the
# last time 'nextpart' was called
nextpart() {
	nextpartread $1 2> $1.prev.tmp
	mv $1.prev.tmp $1.prev

# copy_setports - Copy Configuration File and Replace Ports
#
# Convenience function to copy a configuration file, replacing the tokens
# QUERYPORT, CONTROLPORT and EXTRAPORT[1-8] with the values of the equivalent

    # tokens when it processes this file and produces conf.sh.
