Hi,
HAProxy 2.1-dev2 was released on 2019/10/01. It added 399 new commits
after version 2.1-dev1.
Yes, I know. 2.1-dev1 was 2.5 months ago and now we're one-off from 400
commits just for dev2. It is quite a mess. The reality is that we've been
spending an insane amount of time away from coding, just doing nasty bug
chasing. Most of those who know me by now know how this drives me nuts,
because instead of spending time rebuilding the things that are falling
apart, we're planting a few nails here and there so that it lasts for yet
another release. There are still some pending bugs but since this is a
never-ending game and we've merged quite some features, I prefer to issue
dev2 now and ease testing than wait for the magical bug-free day.
The positive thing is that some very long-lasting issues related to aborted
H2 requests and uploads are now dead, and that the checks, eventhough the
code it getting uglier each week, now work much better. But all that still
needs to be done to address the shutdown vs abort issues, idle connections
sharing, sending of H2 CONTINUATION frames to support large response headers
in H2 and the complete rewrite of the checks... all these still have to be
done and most of them will definitely not be for 2.1 anymore.
But overall I'm staying positive. Killing a bug is still an improvement.
Since 2.1-dev1, we killed 124 of them, that's almost 2 per day including
week-ends, which is quite an amazing score, especially for a vacation
period!
And since I'm not seeing this trend go significantly down and predict some
of us will have less time to spend on this with the upcoming conference,
I'd like to urge a code freeze very soon. I'd have set it to yesterday but
doing so without prior notification is not friendly and it's my fault for
not having seen time fly this fast. So I'll take my share of the responsibility
for the situation and accept an extra delay... only for the stuff I've been
made aware of. Thus I proclaim that I'm not going to take anything that I've
not yet been told about right now, and will stop taking impacting changes
past Sunday 13th this month so that we can mostly focus on fixing issues,
polishing docs and adding more regtests if possible. Note that this must
not be used as an excuse for sending half-tested crap and hoping to fix it
later.
Now let's have a look at the new goodies in this version :
- HTX is now the only supported HTTP mode, the old "legacy" mode was
now removed. Good riddance, less maintenance hell! This remains
transparent, unless you try to specify "no option http-use-htx"
where you'll get an error.
- removal of rsprep / reqrep etc... These were the oldest rules, still
applying to a whole HTTP line (header or not). Not only they were not
very reliable to use (syntax, spaces, ...), but they required to emulate
a dummy request when dealing with H2, which didn't make any sense
anymore. Plus it was not possible to use case-sensitivity only on the
value without having it on the name...
- the HTTP/1 mux now supports remapping header names when dealing with a
bogus application that is having issues with case sensitivity. Please
see "h1-case-adjust" in the doc for this if you're dealing with such
issues.
- we now support connecting to FastCGI backends. This was a direct outcome
of supporting multiplexed connections everywhere, it was too tempting to
give it a try. This can help improve resource management for example by
limiting the number of concurrent requests much more accurately, and
reducing the number of containers deployed in certain environments when
a component such as nginx or lighttpd had to be deployed solely to serve
as an HTTP-to-FCGI gateway.
- the FD cache was completely removed. This was a leftover from the very
old "speculative I/O" mode allowing to save a lot of syscalls in
callbacks by keeping track of the last polling status. Now that our
I/Os are called from top to bottom, it's not needed anymore, and can
increase the performance up to ~20% on some artificially tailored
workloads, but I still expect 5-10% in real production.
- connections take much less memory as the source and destination
addresses are now dynamically allocated if needed. That's 128 to 256
bytes saved per connection and per side in the common case.
- the thread dump used in panic code can now show Lua backtraces, so that
in the event time is wasted in Lua (it should not, unless if you call
an external library), it is possible to know the exact line of the Lua
code that provoked this.
- a trace infrastructure was added to help collect information from the
field without having to recompile. Traces can be enabled from the CLI
and collect data from several places with varying levels of details,
and send them to stdio, log servers or ring buffers. As of dev2, the
only source is the H2 mux.
- as a bonus from the trace infrastructure, logs can now be sent to a ring
buffer (only one, 1 MB for now, just requires config keywords to create
more). This can be very convenient in some environments since just issuing
a "show events buf0" on the CLI will show everything, and adding "-w -n"
after it will work like "tail -f".
- the SSL certificate management was significantly reworked to centralize
certificate information so that certs are now loaded a single time even
if multiple bind lines use them, and perform way less system calls. This
is expected to substantially speed up loading of large setups where numbers
in the orders of 10k to 100k certs are used. Some extra improvements are
still pending on this (no more details, I'd rather avoid saying crap).
- a part of the scheduler was improved to support waking up tasklets
belonging to another thread. It is a necessary step to deal with inter-
thread idle connections, but allowed to simplify quite some parts of the
code and to speed up the accept() code.
- SPOE now sends a per-thread engine-id allowing to support async mode with
threads.
- the stats page can now be exported in JSON mode, finally!
- add new build target linux-glibc-legacy (for CentOS 6 and older)
- new sample fetches and converters: srv_queue, fc_pp_authority, uuid
- send-proxy-v2 can now send the authority, allowing to chain layers using
SNI.
I've intentionally skipped many entries as you can guess, the change log
is quite large, but this is what I spotted. And I skipped the 124 bugfixes
as they are not new features :-) Thanks to all participants for these
efforts, especially the detailed bug reports. Now it's the users' turn to
spot bugs and refill our bag!
