Nick Ramirez reported that the wording is confusing and lets one think
that the CR or LF are both optional, which is not the case (either is
optional). Let's reformulate this.
In session, don't keep an infinite number of connection that can idle.
Add a new frontend parameter, "max-session-srv-conns" to set a max number,
with a default value of 5.
Instead of the old "idle-timeout" mechanism, add a new option,
"pool-purge-delay", that sets the delay before purging idle connections.
Each time the delay happens, we destroy half of the idle connections.
Add a new command, "pool-max-conn" that sets the maximum number of connections
waiting in the orphan idling connections list (as activated with idle-timeout).
Using "-1" means unlimited. Using pools is now dependant on this.
Change the default for http-reuse from "never" to "safe", as it has been
the recommended setting for a few versions now and backend H2 makes little
sense without it.
Some warnings were removed from the config parser since it can dynamically
be disabled depending on the server's configuration, so there's no need to
disable it on a whole backend just for one server.
Caching the response with the compression enabled was totally broken. To fix the
problem, the compression must be done after caching the response. Otherwise it
needs to change the cache to store compressed and uncompressed objects for the
same ressource. So, because it is not possible for now, it is forbidden to
declare the compression filter before the cache one. To ease the configuration,
both can be implicitly declared (without "filter" keyword). The compression will
automatically be inserted after the cache.
Then, to make it works this way, the compression filter has been slighly
modified. Now, the response headers are updated after http-response rules
evaluations, instead of before. So, if the response contains a "Content-length"
header, it will be kept with the response stored in the cache. So this cached
response will be able to be served to clients not supporting the compression at
all.
If a reload was issued to the master process and failed, it is critical
that the admin sees it because it means that the saved configuration
does not work anymore and might not be usable after a full restart. For
this reason in this case we modify the "master" prompt to explicitly
indicate that a reload failed.
Handle the CLI level in the master CLI. In order to do this, the master
CLI stores the level in the stream. Each command are prefixed by a
"user" or "operator" command before they are forwarded to the target
CLI.
The level can be configured in the haproxy program arguments with the
level keyword: -S /tmp/sock,level,admin -S /tmp/sock2,level,user.
Implement "show cli level" which show the level of the current CLI
session.
Implement "operator" and "user" which lower the permissions of the
current CLI session.
Change the output of the relative pid for the old processes, displays
"[was: X]" instead of just "X" which was confusing if you want to
connect to the CLI of an old PID.
Since HTX casts the buffer to a struct and stores relative pointers at the
end, it is mandatory that its end is properly aligned. This patch enforces
a buffer size rounding up to the next multiple of two void*, thus 8 on
32-bit and 16 on 64-bit, to match what malloc() already does on the beginning
of the buffer. In pratice it will never be really noticeable since default
sizes already are such multiples.
As for the compression filter, the cache filter must be explicitly declared
(using the filter keyword) if other filters than cache are used. It is mandatory
to explicitly define the filters order.
Documentation has been updated accordingly.
Make it obvious in the description of the sni directive that it can
not be used for health checks, and refer to the appropriate directive.
This can be backported to 1.8 as check-sni appeared in 1.8.
Make it more obvious that check-sni requires an argument, and that
it can only be a string. Also refer to sni for proxied traffic.
This can be backported to 1.8 as check-sni appeared in 1.8.

Add a new keyword for servers, "idle-timeout". If set, unused connections are
kept alive until the timeout happens, and will be picked for reuse if no
other connection is available.
This switches explicit calls to various trivial registration methods for
keywords, muxes or protocols from constructors to INITCALL1 at stage
STG_REGISTER. All these calls have in common to consume a single pointer
and return void. Doing this removes 26 constructors. The following calls
were addressed :
- acl_register_keywords
- bind_register_keywords
- cfg_register_keywords
- cli_register_kw
- flt_register_keywords
- http_req_keywords_register
- http_res_keywords_register
- protocol_register
- register_mux_proto
- sample_register_convs
- sample_register_fetches

In some situations, especially when dealing with low latency on processors
supporting a variable frequency or when running inside virtual machines,
each time the process waits for an I/O using the poller, the processor
goes back to sleep or is offered to another VM for a long time, and it
causes excessively high latencies.
A solution to this provided by this patch is to enable busy polling using
a global option. When busy polling is enabled, the pollers never sleep and
loop over themselves waiting for an I/O event to happen or for a timeout
to occur. On multi-processor machines it can significantly overheat the
processor but it usually results in much lower latencies.
A typical test consisting in injecting traffic over a single connection at
a time over the loopback shows a bump from 4640 to 8540 connections per
second on forwarded connections, indicating a latency reduction of 98
microseconds for each connection, and a bump from 12500 to 21250 for
locally terminated connections (redirects), indicating a reduction of
33 microseconds.
It is only usable with epoll and kqueue because select() and poll()'s
API is not convenient for such usages, and the level of performance they
are used in doesn't benefit from this anyway.
The option, which obviously remains disabled by default, can be turned
on using "busy-polling" in the global section, and turned off later
using "no busy-polling". Its status is reported in "show info" to help
troubleshooting suspicious CPU spikes.
These sample fetch keywords report performance metrics about the task calling
them. They are useful to report in logs which requests consume too much CPU
time and what negative performane impact it has on other requests. Typically
logging cpu_ns_avg and lat_ns_avg will show culprits and victims.
This is a new global setting which enables or disables CPU profiling
per task. For now it only sets/resets the variable based on the global
option "profiling.tasks" and supports showing it as well as setting it
from the CLI using "show profiling" and "set profiling". The option will
be used by a future commit. It was done in a way which should ease future
addition of profiling options.

This format is pretty similar to the previous "short" format except
that it also removes the severity level. Thus only the raw message is
sent. This is suitable for use in containers, where only the raw
information is expected and where the severity is supposed to come
from the file descriptor used.
This format is meant to be used with local file descriptors. It emits
messages only prefixed with a level, removing all the process name,
system name, date and so on. It is similar to the printk() format used
on Linux. It's suitable to be sent to a local logger compatible with
systemd's output format.
Note that the facility is still required but not used, hence it is
suggested to use "daemon" to remind that it's a local logger.
Example :
log stdout format short daemon # send everything to stdout
log stderr format short daemon notice # send important events to stderr
In certain situations it would be desirable to log to an existing file
descriptor, the most common case being a pipe between containers or
processes. The main issue with pipes is that using write() on them will
randomly truncate messages. But there is a trick. By using writev(), we
can atomically deliver or drop a message, which perfectly fits the
purpose. The only caveat is that large messages (4096 bytes on modern
operating systems) may be interleaved with messages from other processes
if using nbproc for example. In practice such messages are rare and most
of the time when users need such type of logging, the load is low enough
for a single process to be running so this is not really a problem.
This logging method thus uses unbuffered writev() calls and is uses more
CPU than if it used its own buffer with large writes at once, though this
is not a problem for moderate loads.
Logging to a file descriptor attached to a file also works with the side
effect that the process is significantly slowed down during disk accesses
and that it's not possible to rotate the file without restarting the
process. For this reason this option is not offered as a configuration
option, since it would confuse most users, but one could decide to
redirect haproxy's output to a file during debugging sessions. Two aliases
"stdout" and "stderr" are provided, but keep in mind that these are closed
by default in daemon mode.
When logging to a pipe or socket at a high enough rate, some logs will be
dropped and the number of dropped messages is reported in "show info".
The "log" statement appears both in the global section and in listeners.
The "format" directive was only documented in the first one. Maybe we
should think about moving this definition to the log section by now.

The independant -> independent error was fixed in 801a0a35 ("DOC: fix
name for "option independant-streams"), but the note about the wrong
name was erroneously fixed in 0e82b92a ("DOC: fix a few config typos").
Restore the "wrong" name so that when reasearching this option people
can actually find it.
Could be backported to 1.8.
Since http-request was first introduced, more and more actions have been
added over time. This makes the "http-request" difficult to read and some
actions were forgotten in the list.
This is an attempt to make the documenation cleaner. In future steps, it
would be great to provide at least one example for each action.

While "option prefer-last-server" only applies to non-deterministic load
balancing algorithms, 401/407 responses actually caused haproxy to prefer
the last server unconditionally.
As this breaks deterministic load balancing algorithms like uri, this
patch applies the same condition here.
Should be backported to 1.8 (together with "BUG/MINOR: only mark
connections private if NTLM is detected").
Instead of marking all connections that see a 401/407 response private
(for connection reuse), this patch detects a RFC4559/NTLM authentication
scheme and restricts the private setting to those connections.
This is so we can reuse connections with 401/407 responses with
deterministic load balancing algorithms later (which requires another fix).
This fixes the problem reported here by Elliot Barlas :
https://discourse.haproxy.org/t/unable-to-configure-load-balancing-per-request-over-persistent-connection/3144
Should be backported to 1.8.
This option makes a proxy use only HTX-compatible muxes instead of the
HTTP-compatible ones for HTTP modes. It must be set on both ends, this
is checked at parsing time.

For caching it will be convenient to have indexes associated with pools,
without having to dereference the pool itself. One solution could consist
in replacing all pool pointers with integers but this would limit the
number of allocatable pools. Instead here we allocate the 32 first pools
from a pre-allocated array whose base address is known so that it's trivial
to convert a pool to an index in this array. Pools that cannot fit there
will be allocated normally.
Since keep-alive mode is the default mode, the passive close has disappeared,
and in the code, httpclose and forceclose options are handled the same way:
connections with the client and the server are closed as soon as the request and
the response are received and missing "Connection: close" header is added in
each direction.
So to make things clearer, forceclose is now an alias for httpclose. And
httpclose is explicitly an active close. So the old passive close does not exist
anymore. Internally, the flag PR_O_HTTP_PCL has been removed and PR_O_HTTP_FCL
has been replaced by PR_O_HTTP_CLO. In HTTP analyzers, the checks done to find
the right mode to use, depending on proxies options and "Connection: " header
value, have been simplified.
This should only be a cleanup and no changes are expected.
This option is frontends specific, so there is no reason to support it on
backends. So now, it is ignored if it is set on a backend and a warning is
emitted during the startup. The change is quite trivial, but the commit is
tagged as MEDIUM because it is a small breakage with previous versions and
configurations using this options could emit a warning now.
