[Libevent-users] ANN: Libevent 2.0.9-rc is released

[Nick Mathewson <nickm@xxxxxxxxxxxxx>]

Libevent 2.0.9-rc is released!

Thanks to many people's hard work, Libevent 2.0 has now had its fourth
release candidate.  You can download it from the Sourceforge site at:

 https://sourceforge.net/projects/levent/files/libevent/libevent-2.0/libevent-2.0.9-rc.tar.gz/download

There's also a pgp signature of it (by me) there, at:

 https://sourceforge.net/projects/levent/files/libevent/libevent-2.0/libevent-2.0.9-rc.tar.gz.asc/download

Don't forget to validate the signature.   The complete list of changes
is available in the ChangeLog file, included with the distribution.

Niels will upload this to monkey.org when he can; he's been super-busy
with his work lately, which is why I've been doing the "lead
developer" stuff these days.

*** What's new in Libevent 2.0.9-rc

Thanks to everybody who reported and fixed bugs in Libevent 2.0.8-rc,
Libevent 2.0.9-rc should be much more stable and a little more
portable, especially if you're using epoll, OpenSSL bufferevents,
filtering bufferevents, IRIX, 64-bit Windows, filtering bufferevents,
evdns*cancel(), or evhttp.  Especially evhttp.

This release was going to be the "2.0.9-stable", but instead it's
still a release candidate.  That's because of the epoll+dup bugs that
forced us to roll back the default behavior of the epoll backend to
not use the faster changelist-based logic.

For a complete list of changes, just see the ChangeLog included with
the source distribution.  HTTP-related changes are split into their
own sections.

*** Fun facts about Libevent 2.0.9-rc:

This release changes a bunch of lines.  Not to fear, though: they're
mostly in the unit tests, the samples directory, and HTTP-related
stuff.

Unit test coverage (by line) is up to 80.04% on my Linux box--finally,
we're over 80% coverage again!  Branch coverage is at 71.01% according
to gcov, up from 69.92%.  More tests are still needed, particularly
for these files:
   WORST LINE COVERAGE -- bufferevent_ratelim.c, evutil.c,
     bufferevent_openssl.c
   WORST BRANCH COVERAGE -- evutil_rand.c, evdns.c, bufferevent_ratelim.c
   MOST UNTESTED LINES -- evnds.c, http.c, evutil.c, buffer.c, event.c
   MOST UNTESTED BRANCHES -- evdns.c, buffer.c, http.c, event.c

*** Status: Libevent 2.0.x-rc and beyond.

Libevent 2.0 is *still* in feature-freeze (we won't add any more
features to it), hack-freeze (no clever backend rewrites,
refactorings, or major performance hacks), and API freeze (all code
written to work with the documented APIs of Libevent 2.0.5-beta should
continue to work with future versions of Libevent).  We might change
our minds about any of the above if there turn out to be exceptionally
good reasons to do so; this is an aspiration, not a promise. ;)

Please upload bug reports and patches to the sourceforge site at
https://sourceforge.net/projects/levent/ .  Feature requests and
non-bugfix enhancements will be acknowledged but politely deferred
till we fork Libevent 2.0 into a stable maintenance branch and start
development on 2.1.  I'm hoping to do that around 2.0.10-stable, which
I hope to have out before the new year.

We're almost out of known bugs with the 2.0.x series.  If you know
about a bug that 2.0.9-rc does not fix, please have a quick look at
the bug tracker to make sure that there is an entry there.  If there
is not, then please don't assume that we remember it, even if you
mentioned it here, or emailed me personally, or such.
