* Creation of pipework branchChris Hall2010-12-211-6/+2

* First beta releaseChris Hall2010-04-061-59/+49
| | | | | | | Various bug fixes and improvements. Running with a fair amount of debug/assert code, which must be removed at some date.
* Revised thread/timer handling, work queue and scheduling.Chris Hall2010-02-161-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Updated quagga thread handling to use qtimers when using the new qpnexus -- so all timers are qtimers in the new scheme. Updated work queue handling so that each work queue item is a single malloced structure, not three. (Only bgpd and zebra use the work queue system.) When using qpnexus the background thread queue is no longer a timer queue, but simply a list of pending background threads. When a background thread is waiting on a timer, it is in the qtimer pile, same like any other thread. When using qpnexus, the only remaining quagga thread queues are the event and ready queues. Revised the qpnexus loop so that only when there is nothing else to do will it consider the background threads. Revised write I/O in the BGP Engine so that all writing is via the connection's write buffer. Revised the write I/O in the Routeing Engine, so that it passes groups of updates in a single mqueue message. This all reduces the number of TCP packets sent (because BGP messages are collected together in the connection's write buffer) and reduces the number of mqueue messages involved. (No need for TCP_CORK.) Code and comments review for the new code. modified: bgpd/bgp_advertise.c modified: bgpd/bgp_common.h modified: bgpd/bgp_connection.c modified: bgpd/bgp_connection.h modified: bgpd/bgp_engine.h modified: bgpd/bgp_fsm.c modified: bgpd/bgp_main.c modified: bgpd/bgp_msg_read.c modified: bgpd/bgp_msg_write.c modified: bgpd/bgp_network.c modified: bgpd/bgp_packet.c modified: bgpd/bgp_packet.h modified: bgpd/bgp_peer.c modified: bgpd/bgp_peer_index.h modified: bgpd/bgp_route.c modified: bgpd/bgp_route_refresh.h modified: bgpd/bgp_session.c modified: bgpd/bgp_session.h modified: bgpd/bgpd.c new file: bgpd/bgpd.cx modified: lib/mqueue.h modified: lib/qpnexus.c modified: lib/qpnexus.h modified: lib/qpselect.c modified: lib/qtimers.c modified: lib/qtimers.h modified: lib/sigevent.c modified: lib/stream.c modified: lib/stream.h modified: lib/thread.c modified: lib/thread.h modified: lib/workqueue.c modified: lib/workqueue.h modified: tests/heavy-wq.c modified: zebra/zebra_rib.c

* Add timer interval handling to lib/qtimerChris Hall (GMCH)2009-12-171-2/+39
| | | | | For some timers it is convenient to have an interval stored in the timer, and to be able to set the timer using that interval.
* Ensure all timeouts are timeout times in qtime_mono_t.Chris Hall (GMCH)2009-12-091-52/+8
| | | | | | | | | | | | | | | | | | Introduced separate types for qtime_mono_t and qtime_real_t, to distinguish the time base of a given value. Revised all users of timeouts so that they are all expressed as qtime_mono_t values, so are all Quagga monotonic time based. Revised qpt_cond_timedwait() so that all condition variables use the same timebase (CLOCK_MONOTONIC if available, by default). Now all timeout times are qtime_mono_t, and are converted to whatever the condition variable is set to, if necessary. Added explicit timeout to mqueue. Fixed qps_pselect() to zeroise result vectors if no fds are reported pending -- seems the O/S does not do this.
* Fixes to lib/qtime.c and lib/qtimers.hChris Hall (GMCH)2009-12-081-2/+2
| | | | Needs to use lldiv in qtime.c on 32bit machine.
* Added qtimer_pile_top_time() to lib/qtimers.cChris Hall (GMCH)2009-12-081-7/+23
| | | | | | | | For use when preparing for pselect or other timed wait. Simplified the handling of pending unsets. Tidied up in heap.c & .h.
* Initial commit for lib/qpselect.c & .h and lib/qtimers.c & .hChris Hall (GMCH)2009-12-061-0/+172
lib/qpselect supports data structure to multiplex between many file descriptors using pselect(). lib/qtimers supports data structures to run multiple timers. Also affected: lib/Makefile.am -- to add the new files lib/memtypes.c -- to add further memory types for the above
