|
|
|

|
|
* Optimize kevent() when it is called with a zero timeout.

|

|
|
|
|
* Avoid calling getsockopt() on file descriptors that are not sockets.

|
|
* Call epoll_wait after linux_kevent_wait_hires()

* Detect regular files correctly

|
|
|
|
* Ensure that calling close() on a file descriptor will remove any
|
|
kevents that reference the descriptor. [merged from ^/branches/stable@551]
|
|
|
|
* Remove the SERIALIZE_KEVENT macro, and always protect kevent_copyin()
|
|
and kevent_copyout() with a mutex.
|
|
|
|
* Remove fine-grained locking at the knote level.
|
|
|
|
* Add a counter that increments on each each kevent() call. When printing
|
|
debug information within kevent(), display the value of the counter.
|
|
This will be helpful when debugging a multithreaded program that may have
|
|
multiple kevent() calls executing in parallel. (Credit: Julien Blache)

2010-09-18 v1.0 r344
|
|
------------------------------------------------------------------------
|
|
|
|
* Support older Linux kernels that do not have the EPOLLRDHUP flag.
|
|
|
|
* Add a portable implementation of the EVFILT_TIMER filter.
|
|
|
|
* Add Solaris to the list of supported platforms.
|
|
|
|
* Fixed the 'make rpm' target to work on CentOS 5.
|
|
|
|
* Modified the manpage to remove unimplemented features.
|
|
|
|
2010-08-05 v0.9.3 r309
|
|
------------------------------------------------------------------------
|
|
|
|
* Fix a typo in kevent_copyin() that caused EV_RECEIPT to set the
|
|
data field incorrectly in some cases.
|

|
|
|
2010-08-05 v0.9.2 r289
|
|
------------------------------------------------------------------------
|
|
|
|
* Fix some build failures on 32-bit platforms related to the debugging
|
|
codepaths being enabled by default.
|
|
|
|
2010-08-04 v0.9.1 r286
|
|
------------------------------------------------------------------------
|
|
|
|
* Prevent dumping of EVFILT_VNODE debugging information to STDOUT.
|
|
|
|
* Fix the 'make clean' target in the testsuite.
|
|
|
|
2010-08-01 v0.9 r285
|
|
------------------------------------------------------------------------
|
|
|
|
* Set kevent.data = 1 for passive sockets that have at least one pending
|
|
connection.
|
|
(Credit to Julien Blache for finding and researching this bug)
|
|
|
|
* Fix various compilation errors under Solaris.
|
|
(Credit to Joakim Johansson for testing and providing patches)
|
|
|
|
* Use the KQUEUE_DEBUG environment variable to turn on debugging output.
|
|
|
|
2010-07-21 v0.8 r264
|
|
------------------------------------------------------------------------
|
|
|
|
* Fix a bug that prevented a knote with the EV_DISPATCH flag from
|
|
being re-enabled after an event had been triggered.
|
|

|

|
2010-06-08 v0.7 r248
|
|
------------------------------------------------------------------------
|
|
|
|
* Add Debian packaging to the ports/ directory and improve the 'make deb'
|
|
target.
|
|
|
|
* Set the library soname version.
|
|
|
|
* Switch from -fPIC to -fpic as the default in CFLAGS.
|
|
|
|
2010-03-28 v0.6 r238
|
|
------------------------------------------------------------------------
|
|
|
|
* Experimental Linux kernel module.
|
|
|
|
* Implement knote modification for signals.
|
|
|
|
* Implement POSIX signal.c
|
|
|
|
2010-02-09 v0.5 r200
|
|
------------------------------------------------------------------------
|
|
|
|
* Prevent namespace pollution by hiding all ELF symbols except for
|
|
kqueue() and kevent().
|
|
|
|
* Add reference counting to the garbage collection mechanism so that
|
|
a kqueue object is never destroyed while multiple threads are using
|
|
it.
|
|
|
|
* Improve scalability by using red-black trees instead of linked lists.
|
|
|
|
* Refactor the internal API to promote modularity and code reuse.
|
|
Five methods are added to each filter: create, modify, delete,
|
|
enable, disable. These replace the copyin() method, which was
|
|
overly complicated.
|
|
|
|
* Remove the fine-grained locking at the filter level, and replace
|
|
it with coarse locking inside kevent(). This simplifys the locking
|
|
implementation and provides a stronger guarantee of reentrancy.
|
|
|
|
* Initial attempt at writing a Linux kernel module. It fails to
|
|
link because sys_epoll_create() and other event-related syscalls
|
|
are not available to kernelspace (?). Need to ask LKML for guidance.
|
|
|
|
* Make unit tests threadsafe and created a stresstest which runs
|
|
the unit tests in parallel.
|
|
|
|
* Use helper functions to reduce the amount of duplicate code in the
|
|
unit tests.
|
|
|
|
2009-12-26 v0.4 r133
|
|
------------------------------------------------------------------------
|
|
|
|
* Incomplete and experimental support for Solaris added.
|
|
|
|
* Lots of work on the test suite.
|
|
|
|
* Replace the buggy GC thread with an event-based alternative.
|
|
|
|
* Do not implicitly set EV_CLEAR in the EVFILT_USER filter.
|
|
|
|
* Adjust the eventlist when EV_RECEIPT causes it to be modified.
|
|
|
|
2009-11-10 v0.3 r84
|
|
------------------------------------------------------------------------
|
|
|
|
* The EVFILT_USER filter has been implemented, but needs additional
|
|
testing.
|
|
|
|
* The EVFILT_PROC filter is partially implemented on Linux, but is
|
|
currently broken.
|
|
|
|
* The unit tests have been moved to a separate subdirectory and now
|
|
function under OpenBSD 4.4 using the native kqueue(2) and kevent(2)
|
|
system calls.
|
|
|
|
* The kqueue_free() function has been removed.
|
|
|
|
* A helper thread performs garbage collection when close(2) is called
|
|
on the file descriptor returned by kqueue().
|
|
|
|
* All symbols in <sys/event.h> that are not implemented are now
|
|
undefined.
|
|
|
|
* Major internal reorganization of the source tree.
|
|
|
|
* A copy-and-paste error in vnode.c has been fixed.
|
|
|
|
* The pthreads library is now required.
|
|
|
|
2009-11-07 v0.2 r59
|
|
------------------------------------------------------------------------
|
|
|
|
* Implement EVFILT_TIMER on Linux.
|
|
|
|
* Fix another 'make install' problem reported by Mario Schwalbe.
|
|
|
|
* Do not link the test program with the pthreads library.
|
|
|
|
* pkg-config no longer requires linking with -lpthread and -lrt.
|
|
|
|
2009-11-05 v0.1 r49
|
|
------------------------------------------------------------------------
|
|
|
|
* Initial stable release.
