* 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.
|
|
the rpmbuild commandline, eg rpmbuild --define 'keep_build 1'
|
|
* thread.c: Kill unused TIMER_NO_SORT bits
|
|
to HACKING (which I added..)
|
|
* memory.c: Make the string field much wider
* memtypes.c: Correct the prefix list str/entry strings
|
|
* Makefile.am: Refer to source files via srcdir variable, fix
out-of-tree build breakage.
|
|
* HACKING: Add some notes about build system changes, to
document common oversights (common for me anyway).
Seperate sections with two newlines, easier to read.
|
|
* 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.
|
|
* 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.
|
|
* bgpd.8,isisd.8,ospf6d.8,ospfd.8,ripd.8,ripngd.8,zebra.8: Fix
spelling mistake: idenifier -> identifier.
|
|
* bgpd.8,isisd.8,ospf6d.8,ospfd.8,ripd.8,ripngd.8,zebra.8: Fix
spelling mistake: intrefaces -> interfaces.

* Makefile.am: Build heavythread
|
|
* heavy-thread.c: Andrew Schorr's adaptation of heavy.c to use a
background thread to avoid responsivity problems.
|
|
* 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.

|
|
|
* heavy.c: Add a timer thread to demonstrate thread interactivity,
Add a daemon_exit command to assist with debugging (eg for memory
tracers, etc..)
|
|
* Makefile.am: pkginfo.%.tmpl is a generated file, srcdir prefix
is not appropriate.
|
|
version of RIPng is v1).
|
|
* Makefile.am: Add @INCLUDES@ and srcdir to allow out-of-tree
builds to work.
|
|
* heavy.c: test programme to show how long-running functions
kill responsiveness. Demonstrating the most niggly problem
left in bgpd.
|
|
* 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.
|
|
* 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.
|
|
* configure.ac: check for gawk, needed to build memtypes.h
|
|
* Makefile.am: memtypes.awk is gawk dependent, use the GAWK automake
var.
* memtypes.h: New file, auto-generated, checked in for convenience.
|
|
* topology/Makefile.am: random.c is a source of libtopology, so list
it.
|
|
* 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).
|
|
* 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.
|
|
* Makefile.am: {i,r}.manifest are (or will be) system provided files
and not in CVS, hence dont depend on them or distribute them.
|
|
|
|
* test-buffer.c: Andrew's buffer tester
* test-memory.c: basic memory tester
* Makefile.am: Add new tests
|
|
|
|
* .cvsignore: Add built files
|
|
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.

|
* configure.ac: Move AC_CANONICAL_* stuff before AM_INIT_AUTOMAKE to
eliminate warning message about AC_ARG_PROGRAM being called
before AC_CANONICAL_TARGET.
|
|
* Makefile.am: README.txt to EXTRA_DIST
* README.txt: new file, package creation, install, usage notes.
|
|
* 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.
|
|
* (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...
|
|
* if_ioctl_solaris.c: (if_lookup_linklocal) fix order of args
in ALL_LIST_ELEMENTS_RO macro.
|
|
* quagga.info: Update to match bgpd.texi addition
|
|
* configure.ac: Fix host string recognition for Solaris Nevada aka
solaris2.10.1, and hopefully future such strings.
|
|
* Makefile.am: topology should not be a conditional SUBDIR,
otherwise make dist breaks.
* topology/Makefile.am: remove EXTRA_DIST of files which dont
exist in that directory, broke make dist.
* isisd.c: (show_isis_generated_topology_cmd) convert LIST_LOOP
* isis_lsp.c: (generate_topology_lsps) ditto
(build_topology_lsp_data) ditto
|
|
* zserv.c (zebra_client_read): Fix bug: first read attempt should
read ZEBRA_HEADER_SIZE minus the number of bytes already read.
Improve efficiency by maintaining a calculation of the number
of bytes read instead of calling stream_get_endp multiple times.
If message length is too small, issue a warning message (not debug)
before closing the connection. And also check that message length
is not too big.
|
|
about IPv6 nexthops.
|
|
status to unsigned here, because we already checked that it isn't
negative or 0.
* rt_netlink.c (netlink_interface_addr): Prefix length belongs to the
address, not to the interface.
* rt_netlink.c (netlink_route_multipath): Fix debug. No useless info
is printed out now and IPv6 info is handeled.

|
family node.
[backport candidate]
|
|
* sigevent.c: On GNU_LINUX, check whether __USE_GNU is already defined.
|
|
* vty.c: (vty_log_fixed) Use casts to (void *) to try to eliminate
compiler warnings when assigning a (const char *) value to
struct iovec iov_base.
|
|
* zebra.h: If GNU_LINUX is defined, then define _GNU_SOURCE. This
fixes a problem where we were not getting the declaration of strnlen
in <string.h>.
