This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
then majorly reworked by myself. You can blame us both now ;)
Avahi is an Implementation the DNS Service Discovery and Multicast DNS
specifications for Zeroconf Computing. It uses D-BUS for communication
between user applications and a system daemon. The daemon is used to
coordinate application efforts in caching replies, necessary to minimize
the traffic imposed on networks.
