### Shell configuration and error handler
#
set -e
set -u
set -o pipefail



### Fatal error handler
#
_fatalError() {
    ERR_FILE="$0"
    ERR_MSG="$1"
    ERR_LINE="${2:--}"
    echo "[$ERR_FILE:$ERR_LINE] ERROR: $ERR_MSG" 1>&2
    exit 1
}



### Message output handlers
#
_echo() {
    echo "[$0] $1"
}
_debug() {
    echo "[$0] [DEBUG] $1"
}



### Public release version/tag verifier
#
# This check (in contrast to the one below) is more strict, and controls what
# format of public release versioning do we actually allow in the current
# releasing process implementation. For now, only these two options:
# - X.Y.Z
# - X.Y.ZrcN

### Determine if release is considered public or not
#
# Stable and RC releases are considered public. Implications (as of this writing)
# are that such releases are subject to more consistency scrutiny.
#
# Git-based preview releases (with -X-gXXXXXXX version suffix) are not considered
# a public repease, even if their packages land in the `testing` channel.
