# This p4_vars file sets the standard SDP bash shell environment.  It contains
# global and default settings for all instances. Source this file with a
# parameter, the SDP instance name. For example, to set the shell environment
# for an instance named acme, do:
#
# $ source /p4/common/bin/p4_vars acme
#
# Note that a '.' (dot) command can be used in place of the world 'source'.
#
# Sourcing this p4_vars file causes the instance-specific settings file to
# be sourced if it exists.  Instance-specific settings files are in the
# /p4/common/config directory.  For the acme instance, the instance-specific
# settings file would be p4_acme.vars. 
#
# If the instance parameter is omitted, an instance name of '1' (the digit one)
# is assumed.

# This file should not be modified. If site-specific overrides or additional
# settings are desired, please add this syntax (like this file):
# /p4/common/config/site_global_vars
#
# If that file exists, it will be sourced in by this file after the settings
# in this file are read in, and before any instance-specific overrides are
# set.

# 
# The goal: We want it so p4_vars can be sourced safely in scripts and in user
# shell environments.  In scripts, we want 'set -u' to be set, as a bash
# programming best practice disallowing reference of undefined variables
# ("unbound variables" in bash parlance).  However, in some versions of
# Linux and more specifically bash, the tab command completion is broken
# if 'set -u' is set, such that when you hit the 'tab' key interactively,
# instead of getting completion, you get a hideous error.  This workaround
# gives you optimal behavior in scripts that have already called 'set -u'
# before sourcing the SDP environment file, as well as interactive shells
# (where the 'set +u' workaround applies).
