NAME
dolock —
lock port for concurrent
builds
SYNOPSIS
dolock |
[-g group]
[-m mode]
lockname [comment ...] |
DESCRIPTION
dolock creates a lock named
lockname using
open(2). If the lock is already held, it will display one single wait
message on stderr, sleep and retry until satisfaction.
If necessary, creates the lock directory, using
-m mode as a mode argument or
the default if that option is not specified, and -g
group as the group owner if that option is
specified.
This implements a locking mechanism for ports building, see ‘LOCK INFRASTRUCTURE’ in ports(7) for details. See also dpb(1) for a complementary lock infrastructure when using dpb.
