Hi,
HAProxy 1.9-dev1 was released on 2018/08/02. It added 651 new commits
after version 1.9-dev0.
Yes I know what some of you are thinking "what, 651 patches for a first
development release ?". Last year, 1.8-dev1 was emitted with half that
in April, 4 months earlier. But by then we only pushed fixes and some
new features to flush the pipe, and that 1.8-dev2 and -dev3 that
followed had even more patches once cumulated.
Here after 1.8, we've got a longer trail of difficult bugs to deal with
and the 1.9 changes were very low level stuff that doesn't bring any
functional value, these were mostly some rearchitectures of certain
sensitive parts, aimed at building the new features on top of them. So
we could have emitted useless and broken versions, but... I don't like
to discourage our users.
Thus 8 months after 1.9-dev0 was created, here comes the first version
really worth testing. Those looking for eye-candy stuff will be a bit
disappointed, I prefer to warn. Among the ~300 patches that were not
backported to 1.8.x (hence that were not bug fixes), I can see :
- a rework of our task scheduler. Now it scales much better with large
thread counts. There are 3 levels now, one priority-aware shared
between all threads, a lockless priority-aware one per thread, and a
per-thread list of already started tasks that can be used as well
for I/O. It results in most of the scheduling work being performed
without any lock, which scales way better. Another nice benefit of
lock removal is that when haproxy has to coexist with another
process on the same CPU, the impact on other threads is much lower
since the threads are very rarely context-switched with a lock held.
- the applets scheduler was killed and replaced by the new scheduler
above. Not only the previous applets scheduler could use quite some
CPU, it didn't make use of priorities, so many applets could use a
lot of CPU bandwidth. I noticed this already with the first attempt
at implementing H2 using applets. Now the task's nice value being
respected, the CLI is much more responsive even under very high
loads, and the stats page can be tuned to have less impact on the
traffic. Same for peers and SPOE which we'll see if they can benefit
from either a boost or a reduced priority.
- a new test suite was introduced, based on "varnish-test" from the
Varnish cache. It was extended to support haproxy and we can now
write test cases, which are placed into the reg-tests directory. It
is very convenient because testing a proxy is a particularly complex
task which depends on a lot of elements and varnish-test makes it
easier to write reproducible test patterns.
- the buffers were completely changed (again). Buffers are redesigned
every 5 years it seems. I probably find it funny. No I don't in
fact. With the introduction of the mux layer, we suffered a bit from
the old design mixing input and output areas in the same buffer, as
it didn't make any sense there and we had to arbitrarily use either
side depending on the data direction, making it impossible to share
code between the two sides. Now the buffers are much simpler and the
code using them at the various layers was significantly simplified.
It will even open the way to an easier evolution towards dynamic
size buffers in the near future. We found some benefits such as
certain operations being doable in zero copy now, which was not
possible previously. This has affected a huge amount of areas in the
code and will make it a bit more painful to backport fixes to 1.8,
but it's not possible to keep a dead code base and expect it to
evolve at the same time!
- the chunks were replaced by the buffers. The API was not changed yet
to avoid adding jokes to the current complexity, but this will be
done on an opportunistic basis. This already allowed us to remove
some code that already existed in buffers.
- the file descriptor cache is now fully lockless. This is the second
part of the important performance-oriented changes that happened. I
remember observing a 40% performance gain on the connection rate on
a 12-core machine compared to 1.8 just with this change. It was quite
tricky and we didn't feel confident emitting a development release
immediately after to be honest!
- the CLI now supports a payload. This will be used to feed some data
(maps, certs, anything) from external scripts. For now this payload
is limited to a whole buffer, but it will be possible to extend this
in the future.
- the internal connection and mux API have started to evolve so that
we can more easily place some protocol processing at the mux layer.
These changes have just begun and we need to make them step by step
because they have huge implications on the rest of the work being
done in parallel. At the moment we have introduced an rx buffer for
the connstream structure, which greatly simplifies the processing of
incoming H2 frames, so much that initially I was not sure I could
fix the chunk processing in 1.8 where it's not available. In this
current version, one extra copy to the rxbuf often happens (e.g.
during uploads), so some may observe a slightly lower performance at
the moment. We're still working on it.
- the queue processing was modified so that we don't need to operate
via the synchronization point. This has resulted in a significant
performance gain for small server maxconn values on threaded
configs, +50% at 8 threads on a test config.
- the connection balancing on SPOE was significantly improved, using a
mechanism more or less equivalent to the leastconn algorithm,
ensuring that we don't overuse certain connections and leave others
idle for too long. This has reduced the high percentiles of SPOA
response time by a large margin.
- ah, one user-visible change, we now support "random" as a new load
balancing algorithm. Some people prefer it over round-robin. It was
trivial to add, probably one hour code+test+doc included, so there
was no excuse for not doing it :-)
- some new fields are supported on the proxy-protocol v2, though I
don't remember exactly which ones.
- the "resolvers" section can now be fed directly from resolv.conf
using the "parse-resolv-conf" directive. The DNS code also supports
new options to enable/disable address deduplication within a farm.
- we also have the usual box of converters / fetchers like "length",
"concat", "strcmp", "crc32c" and I don't know what else.
As usual, I must have forgotten a lot of stuff, so if you contributed
something that is not listed above, don't feel offended, it's not that I
find it useless, it simply is that I didn't catch it in the middle of
the 651 lines of the changelog (in this case feel free to mention it in
response to this message if you want others to try it).
There's still a lot of stuff pending. One could think that we've merged
the hardest but I don't think so. The ongoing changes to the connection
layer are still a daily discussion subject between some of us, and a
real pain point. And to add a bit of spice, we have to be careful not to
change everything all the time because the most complex part still
coming is highly impacted by each and every change in this area. This
part is the native HTTP transformation, which will be needed for H2 to
work on the backend side. Now it should be easier to modify the checks
code to perform dynamic buffer allocation and save ~32kB of RAM per
server. I'll see if I can work on this at the end, but I'll be glad if
someone beats meto it. I know that there are also some changes to come
on the master-worker area, and still some optmizations under review.
Some patches have been reviewed already in order to support updating and
loading certificates from the CLI. That gave us quite some work figuring
some limitations in the current certificate representation model which
would partially alienate the benefits of this change, so we have
identified a list of updates to be performed on the cert layer first
before being able to definitely merge this patch. At this point it's
unsure whether this will be doable before 1.9 or not (it was not in the
initial roadmap though).
The most complex changes, by far are the HTTP changes for the native
representation (called "HTX" internally). So some of us are less
responsive than usual because this requires a lot of undisturbed focus
and I'd say that we spot a complex showstopper almost every week that
needs to be addressed by breaking lots of stuff underneath.
Overall if we continue on this trend, 1.9 will be very clean from an
architecture perspective. Sometimes we'd like to stop the refactoring
work but it's really hard to find workarounds to certain decades-old
limitations.
Obviously just like with every -dev1, only put it in production if you
want to seek a new job. "It works for me" is the most accurate
description I could provide. I'll probably place it on haproxy.org
sooner or later to see, and to eat my own dog food. Your feedback on
issues will be much valuable, but as I mentioned, it's highly likely
that the best short-term response will be "sorry, please revert for
now", and that we'll just take note of the issue, trying to work on
it a bit later. So no rush needed on the tests. The final release is
still expected in about 3 months.
