# Based on the nightly script from the integration folks,
# Mostly modified and owned by mike_s.
# Changes also by kjc, dmk.
#
# BRINGOVER_WS may be specified in the env file.
# The default is the old behavior of CLONE_WS
#
# -i on the command line, means fast options, so when it's on the
# command line (only), lint, check, GPROF and TRACE builds are skipped
# no matter what the setting of their individual flags are in NIGHTLY_OPTIONS.
#
# LINTDIRS can be set in the env file, format is a list of:
#
#   /dirname-to-run-lint-on flag
#
#   Where flag is:  y - enable lint noise diff output
#           n - disable lint noise diff output
#
#   For example: LINTDIRS="$SRC/uts n $SRC/stand y $SRC/psm y"
#
# -A flag in NIGHTLY_OPTIONS checks ABI diffs in .so files
# This option requires a couple of scripts.
#
# OPTHOME and TEAMWARE may be set in the environment to override /opt
# and /opt/teamware defaults.
#

#
# The CDPATH variable causes ksh's `cd' builtin to emit messages to stdout
# under certain circumstances, which can really screw things up; unset it.

USAGE='Usage: nightly [-in] [-V VERS ] [ -S E|D|H ] <env_file>

Where:
    -i  Fast incremental options (no clobber, lint, check, gprof, trace)
    -n      Do not do a bringover
    -V VERS set the build version string to VERS
    -S  Build a variant of the source product
        E - build exportable source
        D - build domestic source (exportable + crypt)
        H - build hybrid source (binaries + deleted source)

    <env_file>  file in Bourne shell syntax that sets and exports
    variables that configure the operation of this script and many of
    the scripts this one calls. If <env_file> does not exist,
    it will be looked for in $OPTHOME/onbld/env.

non-DEBUG is the default build type. Build options can be set in the
NIGHTLY_OPTIONS variable in the <env_file> as follows:

    -A  check for ABI differences in .so files
    -C  check for cstyle/hdrchk errors
    -D  do a build with DEBUG on
    -F  do _not_ do a non-DEBUG build
    -G  gate keeper default group of options (-au)
    -I  integration engineer default group of options (-ampu)
    -M  do not run pmodes (safe file permission checker)
    -N  do not run protocmp
    -P  do a build with GPROF on
    -R  default group of options for building a release (-mp)
    -T  do a build with TRACE on
    -U  update proto area in the parent
    -V VERS set the build version string to VERS
    -X  copy x86 IHV packages
    -a  create cpio archives
    -d  use Distributed Make (default uses Parallel Make)
    -f  find unreferenced files
    -i  do an incremental build (no "make clobber")
    -l  do "make lint" in $LINTDIRS (default: $SRC y)
    -m  send mail to $MAILTO at end of build
    -n      do not do a bringover
    -o  build using root privileges to set OWNER/GROUP (old style)
    -p  create packages
    -r  check ELF runtime attributes in the proto area
    -t  build and use the tools in $SRC/tools
    -u  update proto_list_$MACH and friends in the parent workspace;
        when used with -f, also build an unrefmaster.out in the parent
    -z  compress cpio archives with gzip
    -W  Do not report warnings (freeware gate ONLY)
    -S  Build a variant of the source product
        E - build exportable source
        D - build domestic source (exportable + crypt)
        H - build hybrid source (binaries + deleted source)
