| Andy Wingo | 2017-02-20 | 4 | -39/+31 |
| * | Add block-asyncs in fiber->thread resume path•••* fibers/operations.scm (perform-operation): Block asyncs in resume
callback; otherwise the fiber doing the resuming could be scheduled
away.
| Andy Wingo | 2017-02-20 | 1 | -4/+6 |
| * | Update (web server fibers)•••* web/server/fibers.scm: Update for new-style nonblocking management.

| Andy Wingo | 2017-02-20 | 1 | -0/+5 |
| * | Fix epoll wakeup•••* fibers/epoll.scm (epoll): Like a complete idiot, I broke epoll
wakeup. Fixed by calling expiry->timeout while epoll-state is
waiting.
| Andy Wingo | 2017-02-20 | 1 | -5/+7 |
| * | Update REPL support for run-fibers changes.•••* fibers/repl.scm (fibers): Update for new run-fibers changes.
| Andy Wingo | 2017-02-20 | 1 | -11/+26 |
| * | Update documentation.•••* fibers.texi (Internals): Document scheduler-work-pending?.
| Andy Wingo | 2017-02-20 | 1 | -0/+5 |
| * | run-fibers returns when initial fiber finishes•••* epoll.c (scm_primitive_epoll_wait): Accept timeout in internal time
units instead of milliseconds. Avoid some overhead if the timeout is
zero.
* fibers/epoll.scm (epoll): Adapt to primitive-epoll-wait chance.
Change get-timeout callback to an "expiry" argument and an
update-expiry last-minute function. Tighten the window around the
"waiting" epoll-state.
* fibers.scm (%run-fibers): Remove current-read-waiter /
current-write-waiter parameterization, given that fibers individually
each have this parameterization.
(run-fibers): Add #:drain? argument.
* fibers/internal.scm (schedule-runnables-for-next-turn): Simplify a
bit, inlining scheduler-poll-timeout and adapting to epoll change.
(scheduler-work-pending?): New function.
(run-scheduler): Simplify finish? logic.
* tests/basic.scm:
* tests/speedup.scm: Update to drain where needed.
* fibers.texi: Update for new run-fibers termination condition.
| Andy Wingo | 2017-02-19 | 7 | -126/+148 |
| * | Fix make -j problem•••* Makefile.am ($(GOBJECTS)): Depend on epoll.la.
| Andy Wingo | 2017-02-19 | 1 | -0/+1 |
| * | Minor documentation update•••* fibers.texi: Bump version and date. Add words about scalability.
| Andy Wingo | 2017-02-19 | 1 | -2/+26 |
| * | Require Guile 2.1.7•••* README.md (Download): Update required Guile version.
| Andy Wingo | 2017-02-18 | 1 | -1/+1 |
| * | Lower preemption overhead•••* fibers/interrupts.scm (with-interrupts/sigprof):
(with-interrupts/thread-cputime, with-interrupts): Separate predicate
from interrupt routine, so that predicate can run off-thread.
* fibers.scm (%run-fibers): Adapt.
| Andy Wingo | 2017-02-17 | 2 | -11/+14 |
| * | Prevent spurious preemption•••* fibers/internal.scm (<scheduler>, make-scheduler):
(scheduler-runcount, run-scheduler): Maintain a count of run fibers.
* fibers.scm (%run-fibers): Only cause the current fiber to suspend if
the runcount isn't advancing.
| Andy Wingo | 2017-02-17 | 2 | -3/+21 |
| * | Add allocation speedup test•••* tests/speedup.scm: Add allocation speedup test.
| Andy Wingo | 2017-02-17 | 1 | -0/+13 |
| * | Take advantage of accept4 interface.•••* fibers/web/server.scm (client-loop): Setvbuf here.
(socket-loop): Use new accept4 interface.
| Andy Wingo | 2017-02-15 | 1 | -2/+2 |
| * | Tweak fibers web socket options•••* fibers/web/server.scm (client-loop): Move NODELAY things here and
actually enable NODELAY (before we were... disabling it???).
(socket-loop): Remove SNDBUF munging; let's assume it doesn't matter
rather than the reverse.
| Andy Wingo | 2017-02-15 | 1 | -7/+4 |
| * | Fix epoll-modify logic•••Because this case wasn't being hit before, there were bugs.
* fibers/internal.scm (<scheduler>): Remove active fd count; we'll add a
#:forever? option to run-fibers instead. Simplify sources.
(make-scheduler): Adapt.
(schedule-fibers-for-fd): Use resume callbacks, to allow for other
kinds of callbacks.
(scheduler-poll-timeout): Don't wait for active fd count to go to
zero.
(finalize-fd): Avoid mucking with hash tables from this potentially-gc
callback.
(add-fd-event-waiter): New function.
(resume-on-fd-events): Call new function.
| Andy Wingo | 2017-02-15 | 1 | -66/+52 |
| * | Add epoll-add*!•••* fibers/epoll.scm (epoll-add*!): New function, tries an epoll-modify!
then falls back to epoll-add!.
| Andy Wingo | 2017-02-15 | 1 | -1/+8 |
| * | fibers/config.scm is built source•••* Makefile.am (BUILT_SOURCES): Mark fibers/config.scm as built.
| Andy Wingo | 2017-02-15 | 1 | -0/+2 |
| * | Parallelize ping client and server.•••* examples/ping-client.scm:
* examples/ping-server.scm: Parallelize.
| Andy Wingo | 2017-02-14 | 2 | -2/+4 |
| * | Fix ping-client•••* examples/ping-client.scm: Fix for run-fibers changes, to only exit
when done.
| Andy Wingo | 2017-02-14 | 1 | -6/+10 |
| * | Fix spurious epoll traffic•••* fibers/internal.scm (schedule-fibers-for-fd): Fix sense of the POLLERR
test. This was causing us to register and unregister our fd's with
the kernel all the time. This was a scalability bottleneck as adding
or removing an fd from an epoll set is serialized in the kernel
through one mutex (!!!!), the "epmutex"; because you can nest epoll
instances the kernel uses this to prevent cycles. Hint found in
Voellmy's paper on the MIO system for Haskell.
| Andy Wingo | 2017-02-14 | 1 | -1/+1 |
| * | Minor tweak to web server•••* fibers/web/server.scm (socket-loop): Move set-nonblocking! call to
client where it parallelizes better.
| Andy Wingo | 2017-02-14 | 1 | -2/+3 |
| * | Gracefully handle EPIPE•••* fibers/web/server.scm (client-loop): Avoid error when reading from
shut-down socket (EPIPE). Perhaps a read that gives EPIPE should
produce an EOF object anyway.
| Andy Wingo | 2017-02-12 | 1 | -3/+4 |
| * | Cope with migration of initial fiber•••* fibers.scm (run-fibers): Allow migration of main fiber.
| Andy Wingo | 2017-02-12 | 1 | -1/+4 |

concurrently.

* tests/foreign.scm: Adapt to sleep-operation change.
| Andy Wingo | 2017-02-11 | 6 | -6/+227 |
| * | Fix channel CAS logic•••* fibers/channels.scm (put-operation, get-operation): Fix bogus CAS that
could cause us to spin in an allocation loop.
| Andy Wingo | 2017-02-08 | 1 | -4/+4 |
| * | Prevent GC from waking up epoll•••* epoll.c (do_epoll_wait): Leave Guile to do the epoll, preventing libgc
from having to interrupt us for GC.
| Andy Wingo | 2017-02-08 | 1 | -7/+27 |
| * | Better exception handling•••* fibers/internal.scm (create-fiber): Add a start-stack and a catch-all
around the fiber thunk. Note that in practice this needs the recent
post-2.1.6 patch in Guile (498f3f95684361f3591106a8f9cb9065fd649288)
to work well.

| * | Disable parallelism in scheduling-order tests•••* tests/basic.scm (assert-run-fibers-terminates): Allow keyword args to
run-fibers.
(run-order, wakeup-order): Disable parallelism.
| Andy Wingo | 2017-01-08 | 1 | -4/+4 |
| * | create-fiber always captures dynamic state•••* fibers/internal.scm (create-fiber): Remove dynamic-state argument;
always capture the current dynamic state.
* fibers/timers.scm (timer-operation):
* fibers.scm (spawn-fiber): Adapt.
| Andy Wingo | 2017-01-08 | 3 | -13/+12 |
| * | Enable preemption by default•••* fibers.scm (run-fibers): Enable preemption by default with a period of
10ms.
| Andy Wingo | 2017-01-08 | 1 | -3/+2 |

all fibers.
