* quagga.info: updated
2005-04-282005-04-28 Paul Jakma <paul.jakma@sun.com>paul
* rib.h: (struct rib) Add lock field for refcounting. * zserv.h: (struct zebra_t) Add a ribq workqueue to the zebra 'master' struct. * zserv.c: (zread_ipv4_add) XMALLOC then memset should be XCALLOC. * zebra_rib.c: Clean up refcounting of route_node, make struct rib refcounted and convert rib_process to work-queue. In general, rib's should be rib_addnode'd and delnode'd to route_nodes, and these symmetrical functions will manage the locking of referenced route_node and freeing of struct rib - rather than having users manage each seperately - with much scope for bugs.. (newrib_free) removed and replaced with rib_lock (rib_lock) new function, check state of lock and increment. (rib_unlock) new function, check lock state and decrement. Free struct rib if refcount hits 0, freeing struct nexthop's, as newrib_free did. (rib_addnode) Add RIB to route_node, locking both. (rib_delnode) Delete RIB from route_node, unlocking each. (rib_process) Converted to a work-queue work function. Functional changes are minimal, just arguments, comments and whitespace. (rib_queue_add_qnode) Helper function to setup a ribq item. (rib_queue_add) Helper function, same arguments as old rib_process, to replace in callers of rib_process. (rib_queue_qnode_del) ribq deconstructor. (rib_queue_init) Create the ribq. (rib_init) call rib_queue_init. (remainder) Sanitise refcounting of route_node's. Convert to rib_queue_add, rib_addnode and rib_delnode. Change XMALLOC/memset to XCALLOC. Remove calls to nexthop_delete and nexthop_free.

Add wall-clock timing statistics to 'show thread cpu' output. * thread.h: Define struct rusage_t to contain wall-clock time and cpu time. Change GETRUSAGE macro to collect both pieces of data. Make appropriate changes to struct cpu_thread_history to track CPU time and real time. Change proto for thread_consumed_time to return real and cpu time elapsed. And declare a new global variable 'struct timeval recent_time'. * thread.c (struct timeval recent_time): New global timestamp variable. (timeval_adjust): If timeout is negative, set to 0 (not 10 microseconds). And remove upper bound of 1,000,000 seconds, since this does not seem to make any sense (and it breaks funcname_thread_add_timer_timeval). (timeval_cmp): Should return long, not int. (vty_out_cpu_thread_history): Show CPU time and real time. (cpu_record_hash_print): Calculate totals for CPU and real time. (cpu_record_print): Change 'show thread cpu' title to show CPU and real time. (thread_timer_remain_second): Put current time in global recent_time. (funcname_thread_add_timer_timeval): Fix assert. Replace 2-case switch assignment with a ternary expression. Use global recent_time variable. Fix use of timeval_adjust (previously, the value was not actually being adjusted). (thread_cancel): Add missing "break" statement in case THREAD_BACKGROUND. (thread_timer_wait): Use global recent_time value instead of calling gettimeofday. And there's no need to check for negative timeouts, since timeval_subtract already sets these to zero. (thread_timer_process): Timers are sorted, so bail out once we encounter a timer that has not yet popped. And remove some extraneous asserts. (thread_fetch): Do not process foreground timers before calling select. Instead, add them to the ready list just after the select. Also, no need to maintain a count of the number of ready threads, since we don't care how many there are, just whether there's one at the head of the ready list (which is easily checked). Stick current time in global variable recent_time to reduce the number of calls to gettimeofday. Tighten logic for calculating the select timeout. (thread_consumed_time): Now returns real time and puts the elapsed cpu time in an additional argument. (thread_should_yield): Use real (wall-clock) time to decide whether to yield. (thread_call): Maintain CPU and real time statistics. * vty.c (vty_command): For slow commands, show real and cpu time.
2005-04-272005-04-27 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* workqueue.c (show_work_queues): Remove unused gettimeofday call.
2005-04-272005-04-27 Paul Jakma <paul.jakma@sun.com>paul
* memory.h: memtypes is built source, default includes points to top_builddir, so we should refer to lib/memtypes.h
2005-04-272005-04-27 Paul Jakma <paul.jakma@sun.com>paul
* workqueue.h: (struct work_queue_item) change retry_count to ran, its a count of number item has been run. * workqueue.c: (show_work_queues) Fix formating of slightly bugfix: fix SIGFPE if wq->runs is 0. (work_queue_run) retry logic was slightly wrong. cycles.best is 0 initialy, granularity is 1, so update best if cycles >= granularity, not just >.
2005-04-262005-04-26 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* buffer.c (buffer_write): Comment out call to buffer_flush_available. This should speed up buffering at the expense of a possible increase in latency in flushing the data if inside a long-running thread.
2005-04-262005-04-26 Paul Jakma <paul.jakma@sun.com>paul
* quagga.xml.in: New, better, single integrated manifest for all the services, courtesy of alan.maguire@sun.com. * {{ospf,ospf6,rip,ripng,bgp}d,zebra}.xml.in: removed due to previous * quagga.init.in: Use the package tarname for properties, use the correct daemon name variable. * Makefile.am: Updated to match single manifest * prototype.daemons.in: ditto
2005-04-26- build isisd per defaultpaul
2005-04-252004-05-25 Paul Jakma <paul@dishone.st>paul
* main.c: new file, common 'main' portion which then calls test_init. * heavy.c: remove common portions now in 'main. * heavy-wq.c: ditto * heavy-thread.c: ditto * heavy*.c: Set the slow_function iteration number lower, to 300, it was several orders of magnitude too 'slow' to be useful. :) * Makefile.am: main is a source of the tests. heavy should link to the math library.
2005-04-25- forgot to commit changelog, belongs to previous commit.paul
2005-04-252005-04-25 Paul Jakma <paul.jakma@sun.com>paul
* workqueue.{c,h}: Helper API for setting up and running queues via background threads. * command.c: install the 'show workqueues' command * memtypes.c: Add work queue mtypes, and a rib-queue type for a zebra rib work queue. * memtypes.h: Updated to match memtypes.c * Makefile.am: Add new workqueue files to build.
2005-04-25- make various defines conditional, so that they can be specified frompaul

2005-04-25- arg, fix the missing slash. Beat myself with the diff of the last commitpaul
to HACKING (which I added..)
2005-04-252005-04-25 Paul Jakma <paul.jakma@sun.com>paul
* memory.c: Make the string field much wider * memtypes.c: Correct the prefix list str/entry strings
2005-04-252005-04-25 Paul Jakma <paul.jakma@sun.com>paul
* Makefile.am: Refer to source files via srcdir variable, fix out-of-tree build breakage.
2005-04-252005-04-25 Paul Jakma <paul.jakma@sun.com>paul
* HACKING: Add some notes about build system changes, to document common oversights (common for me anyway). Seperate sections with two newlines, easier to read.
2005-04-222005-04-22 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* thread.h: Fix type for struct thread_master add_type: should be unsigned char. Also, add some documentation of thread_add_background args. And remove extraneous declaration of show_thread_work_queues_cmd.
2005-04-222005-04-22 Paul Jakma <paul.jakma@sun.com>paul
* memory.h: Move include of memtypes.h to after the definition of struct memory_list, gcc 4.0 doesn't like arrays of incomplete types.

* Makefile.am: Build heavythread
2005-04-222004-05-22 Paul Jakma <paul@dishone.st>paul
* heavy-thread.c: Andrew Schorr's adaptation of heavy.c to use a background thread to avoid responsivity problems.
2005-04-222005-04-22 Paul Jakma <paul.jakma@sun.com>paul
* thread.h: Add background thread type and thread_add_background macro and accompanying funcname_... function. export thread_should_yield, background threads can use it. Lower thread yield time to 10ms, 100ms is noticeable lag and a thread would only be /starting/ to finish sometime afterward. * thread.c: (general) Add background thread type and schedule nearly all thread types through the ready list for fairness. (timeval_adjust) static qualifier missing (vty_out_cpu_thread_history) add support for printout of background threads (show_thread_cpu) ditto. (thread_master_debug) add debug of background list (thread_master_create) fixup long line (thread_add_unuse) add asserts for required state. (thread_master_free) free background thread list (funcname_thread_add_timer_timeval) make generic, able to support arbitrary timer-like thread types. (funcname_thread_add_timer) pass thread type to .._add_timer_timeval (funcname_thread_add_timer_msec) ditto (funcname_thread_add_background) Add a background thread, with an optional millisecond delay factor, using .._add_timer_timeval. (thread_cancel) Add background thread type. Move the thread_list_delete common to all cases to bottom of function, after the switch statement.. (thread_cancel_event) indent (thread_timer_wait) Static qualifier, and make it able to cope with arbitrary timer-like thread lists, so its of use to background threads too. (thread_process_fd) static qualifier. Again, make it take a list reference rather than thread_master. Fix indentation. (thread_timer_process) Check for ready timer-like threads in the given list and move them on to the ready list - code originally embedded in thread_fetch. (thread_fetch) Schedule all threads, other than events, through the ready list, to ensure fairness. Timer readying code moved to thread_timer_process so it can be reused for background threads. Remove the unneeded quagga_sigevent_process, as pointed out by John Lin <john.ch.lin@gmail.com>. (thread_should_yield) make this available.

2005-04-212004-05-21 Paul Jakma <paul@dishone.st>paul
* heavy.c: Add a timer thread to demonstrate thread interactivity, Add a daemon_exit command to assist with debugging (eg for memory tracers, etc..)
2005-04-212005-04-21 Paul Jakma <paul.jakma@sun.com>paul
* Makefile.am: pkginfo.%.tmpl is a generated file, srcdir prefix is not appropriate.
2005-04-20There is no RIPv3. It is a RIPng (by the way for your information, the ↵jardin
version of RIPng is v1).
2005-04-202005-04-20 Paul Jakma <paul@dishone.st>paul
* Makefile.am: Add @INCLUDES@ and srcdir to allow out-of-tree builds to work.
2005-04-192004-05-19 Paul Jakma <paul@dishone.st>paul

2005-04-162005-04-16 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* configure.ac: Added AC_ARG_ENABLE(time-check). By default, warning messages will now be printed for threads or commands that take longer than 5 seconds, but this configure argument can be used to disable the checks or change the threshold. * thread.h (thread_consumed_time): Declare new function to calculate elapsed microseconds. * thread.c (thread_consumed_time): Must be global not static so we can call it from lib/vty.c:vty_command. (thread_should_yield): Surround with `#if 0' to make clear that this function is not currently being used anywhere. (thread_call): If CONSUMED_TIME_CHECK is defined, print a CPU HOG warning message if the thread takes more than CONSUMED_TIME_CHECK microseconds. * vty.c (vty_command): If CONSUMED_TIME_CHECK is defined, print a CPU HOG warning message if the command takes more than CONSUMED_TIME_CHECK microseconds.
2005-04-162005-04-16 Paul Jakma <paul@dishone.st>paul
* memtypes.c: the comment about use of comments in the comments headers was causing comment within comment warnings from compiler * memtypes.awk: Add extensive comments on the file format for memtypes.c. tighten the pattern for the MTYPE matching action (suggestion from Andrew) and tighten which field we try the match on.
2005-04-162005-04-16 Paul Jakma <paul.jakma@sun.com>paul
* configure.ac: check for gawk, needed to build memtypes.h
2005-04-152005-04-15 Paul Jakma <paul@dishone.st>paul
* Makefile.am: memtypes.awk is gawk dependent, use the GAWK automake var. * memtypes.h: New file, auto-generated, checked in for convenience.
2005-04-152005-04-15 Paul Jakma <paul@dishone.st>paul
* topology/Makefile.am: random.c is a source of libtopology, so list it.
2005-04-152005-04-15 Zhipeng Gong <zpgong@cdc.3upsystems.com>paul
* ospf_abr.c: (ospf_abr_announce_network_to_area) dont forget to approve LSAs for the case where metric has changed, lsa gets flushed otherwise. (backport candidate).
2005-04-152005-04-15 Paul Jakma <paul@dishone.st>paul
* memtypes.c: The new, unified location for memory type definitions. The memtype enum and declarations for memory_lists are built from this automatically and put into memtypes.h. * memtypes.awk: New script to generate memtypes.h from memtypes.c * memory.h: Finally, the enum can banished! * memory.c: Finally, the seperate mtype memory_list definitions can be banished! (log_memstats) Increase width of fields (show_memory_zebra_cmd) display zebra specific memory types. Increase width of fields. * Makefile.am: Add memtypes.{c,h}, add BUILT_SOURCES for memtypes.h Add a rule to build memtypes.h using memtypes.awk. Add memtypes.awk to EXTRA_DIST.
2005-04-132005-04-13 Paul Jakma <paul.jakma@sun.com>paul
* Makefile.am: {i,r}.manifest are (or will be) system provided files and not in CVS, hence dont depend on them or distribute them.

Implement non-blocking zclient I/O with buffering. * zclient.h (struct zclient): Add two fields to support non-blocking I/O: struct buffer *wb, and struct thread *t_write. (zclient_free): Remove function. (zebra_redistribute_send): Change 2nd arg from socket fd to struct zclient * (needed to support non-blocking I/O and buffering). (zclient_send_message): New function to send an arbitrary message with non-blocking I/O. * zclient.c (zclient_new): Create write buffer. (zclient_free): Remove unused function. (zclient_stop): Must cancel new t_write thread. Also, reset all buffers: ibuf, obuf, and wb. (zclient_failed): New helper function for typical error handling. (zclient_flush_data): New thread to flush queued data. (zclient_send_message): New function to send the message in zclient->obuf to zebra using non-blocking I/O and buffering. (zebra_message_send, zapi_ipv4_route, zapi_ipv6_route): Use new zclient_send_message function instead of calling writen. (zclient_start): Set socket non-blocking. Also, change 2nd arg to zebra_redistribute_send from zclient->sock to zclient. (zebra_redistribute_send): Change 2nd arg to struct zclient *. Can now use zclient->obuf to assemble the message instead of allocating a temporary stream. And call zclient_send_message to send the message instead of writen. (zclient_read): Convert to support non-blocking I/O by using stream_read_try instead of deprecated stream_read. (zclient_redistribute): Change 2nd arg to zebra_redistribute_send from zclient->sock to zclient. * ospf6_zebra.c (ospf6_zebra_redistribute, ospf6_zebra_no_redistribute): Change 2nd arg to zebra_redistribute_send from zclient->sock to zclient. * ospf_zebra.c (ospf_zebra_add): Call zclient_send_message instead of writen. * rip_zebra.c (rip_redistribute_set, rip_redistribute_unset, rip_redistribute_clean): Change 2nd arg to zebra_redistribute_send from zclient->sock to zclient. * ripng_zebra.c (ripng_redistribute_unset, ripng_redistribute_clean): Change 2nd arg to zebra_redistribute_send from zclient->sock to zclient. * bgp_zebra.c (bgp_redistribute_set, bgp_redistribute_unset): The 2nd arg to zebra_redistribute_send is now zclient instead of zclient->sock. * isis_zebra.h (isis_zebra_finish): Remove declaration of unused function. * isis_zebra.c (isis_zebra_route_add_ipv4): Call zclient_send_message to send the message to zebra instead of calling writen directly, since zclient_send_message understands non-blocking I/O and will manage the buffer queue appropriately. (isis_zebra_finish): Remove unused function, particularly since the zclient_free function has been removed.
2005-04-112005-04-11 Andrew J. Schorr <ajschorr@alumni.princeton.edu>ajs
* configure.ac: Move AC_CANONICAL_* stuff before AM_INIT_AUTOMAKE to eliminate warning message about AC_ARG_PROGRAM being called before AC_CANONICAL_TARGET.
2005-04-112005-04-11 Paul Jakma <paul.jakma@sun.com>paul
* Makefile.am: README.txt to EXTRA_DIST * README.txt: new file, package creation, install, usage notes.
2005-04-112005-04-11 Paul Jakma <paul.jakma@sun.com>paul
* configure.ac: Call AC_CANONICAL_{BUILD,TARGET} macros. Target isnt set otherwise, afaict. AC_SUBST enable_{user,group,vty_group} and quagga_statedir - the Solaris package bits for one need this. configure the solaris/ Makefile. * Makefile.am: solaris is a subdir - unconditional or else it wont be included in non-solaris made dists.
2005-04-112005-04-11 Paul Jakma <paul.jakma@sun.com>paul
* (all) Initial check-in of files for building S10 packages * protototype.*.in: package prototype files for SysV packages * *.xml.in: SMF manifests for Quagga daemons * pkginfo.*.tmpl.in: daemon specific pkginfo, refererenced by prototype files. * pkginfo.tmpl.in: Quagga common pkginfo bits * quagga.init.in: SMF method script * Makefile.am: Automake file for building packages * depend.*: Solaris 10 dependencies for packages, referenced by prototype files. * .cvsignore: no idea what this is for...
