Define a new build mode DEBUG_STRESS. This will be used to stress some
code parts which cannot be reproduce easily with an alternative
suboptimal code.
First, a global <mode_stress> is set either to 1 or 0 depending on
DEBUG_STRESS compilation. A new global keyword "stress-level" is also
defined. It allows to specify a level from 0 to 9, to increase the
stress incurred on the code.
Helper macro STRESS_RUN* are defined for each stress level. This allows
to easily specify an instruction in default execution and a stress
counterpart if running on the corresponding stress level.

in 50322dff ("MEDIUM: server: add init-state"), some examples on how to
use init-state server keyword were added alongside with the keyword
documentation.
However, as reported by Nick Ramirez, there was an error because the
example that stated that haproxy will pass the traffic to the server after
3 successful health checks used the "init-state down" instead of the
"init-state fully-down". Thus the behavior wouldn't match what the
comment said (only 1 successful health check was required).
Here we fix the example in itself to match with the comment. Also the
following example ("# or") was also affected, but it is kind of
redundant as the main purpose of the examples are to illustrate the
feature in itself and not how to use server-template directive, so we
remove it.
This should be backported in 3.1 with 50322dff
When "recv-only" keyword is added on a stick table declaration (in peers
or proxy section), haproxy considers that the table is only used for
data retrieval from a remote location and not used to perform local
updates. As such, it enables the retrieval of local-only values such
as conn_cur that are ignored by default. This can be useful in some
contexts where we want to know about local-values such are conn_cur
from a remote peer.
To do this, add stktable struct flags which default to NONE and enable
the RECV_ONLY flag on the table then "recv-only" keyword is found in the
table declaration. Then, when in peer_treat_updatemsg(), when handling
table updates, don't ignore data updates for local-only values if the flag
is set.
The "421" status can now be specified on retry-on directives. PR_RE_* flags
were updated to remains sorted.
This patch should fix the issue #2794. It is quite simple so it may safely
be backported to 3.1 if necessary.

The QUIC pacing options changed a few times during their development.
For example the unit is now in datagrams not bytes. Also a few
sentences were slightly ambiguous so let's reword this.
No backport is needed.
Miroslav mentioned below that he's currently working on an OpenTelemetry
replacement for the OpenTracing filter since OpenTracing itself is no
longer maintained nor supported:
https://github.com/haproxy/haproxy/issues/2782#issuecomment-2493576327
Given that he aims for 3.2, let's already settle on an upcoming deprecation
of the filter for 3.3 with a removal for 3.5. This will leave time to finish
the development and permit users to switch smoothly. At this point no warning
is emitted (since the users have no alternative) but better mention this plan
in the doc to make them aware of future changes.

This fixes the commit d6ccd1738bae
("MINOR: startup: set HAPROXY_LOCALPEER only once"). HAPROXY_LOCALPEER could
be checked in the configuration to set some servers settings or listeners. So,
we need to set it just before we read the configuration at the second time.
Let's mark HAPROXY_LOCALPEER as "usable" in the configuration in the related
documentation chapter.
This should not be backported, as related to the latest master-worker
refactoring.
Recently, pacing support was added for cubic congestion algorithm. This
was activated by using the new token "cubic-pacing" on quic-cc-algo.
Furthermore, it was possible to define a burst size with a new
parameters after congestion token between parenthesis.
This configuration is not oblivious to users. In particular, it can
cause to easily forgot to tweak burst size, which can dramatically
impact performance.
Simplify this by removing the extra "-pacing" suffix. Now, pacing will
be activated solely based on the burst parameter. If 0, burst is
considered as infinite and no pacing will be used. Pacing will be
activating for any positive burst. This better reflects the link between
pacing and burst and its importance.
Note that for the moment, if burst is specified, it will be ignored with
a warning for algorithm outside of cubic.
This is not a breaking change as pacing support was implemented in the
current dev version.
The description was inproved to clrealy mentionned it is applied on received
requests and responses. In addition, a comment was added about HTTP/2 and
HTTP/3 limitation when messages are encoded to be sent.
Add this new "bbr" option to the list of the congestion control algorithms which
may be set by "quic-cc-algo" setting.
This new algorithm is considered as experimental and may be enabled only if
"expose-experimental-directive" is set.
Also update the documentation for this new setting.
In the doc our lists are indented but for any reason this one was not,
making it harder to visually delimit. Let's just indent it. No need to
backport this, it's totally cosmetic and would need adaptations since
it was recently touched.
There are some variables, which are set by HAProxy process (HAPROXY_*). Some
of them are handy to check or to redefine in the configuration, in order to
create conditional blocks and make the configuration more flexible. But it
wasn't clear in the documentation, which variables are really safe and usefull
to redefine and which ones could be only read via "show env" output.
Latest changes in master-worker architecture makes the existed description even
more confusing.
So let's sort all HAPROXY_* variables to four categories and let's also mark
explicitly, which ones are set in which process, when haproxy is started in
master-worker mode.
In addition, update examples in chapter "2.4. Conditional blocks". This might
bring more ideas for users how HAPROXY_* variables could be used in the
conditional blocks.
As mentionned by Thayne McCombs in #2728, it could be handy to have a sample
fetch function to retrieve the query string with the question mark
character.
Indeed, for now, "query" sample fetch function already extract the query
string from the path, but the question mark character is not
included. Instead of adding a new sample fetch function with a too similar
name, an optional argument is added to "query". If "with_qm" is passed as
argument, the question mark will be included in the query string, but only
if it is not empty.
Thanks to this patch, the following rule:
http-request redirect location /destination?%[query] if { -m found query } some_condition
http-request redirect location /destination if some_condition
can now be expressed this way:
http-request redirect location /destination%[query(with_qm)] if some_condition
Conditional blocks inherit the same tokenizer and argument parser as
the rest of the configuration, but are also silently concatenated
around groups of spaces and tabs. This can lead to subtle failures
for configs containing spaces around commas and parenthesis, where
a string comparison might silently fail for example. Let's better
document this particular case.
Thanks to Valentine for analysing and reporting the problem.
This can be backported to 2.4.
Spaces around commas or parenthesis in expressions are generally part
of the value due to the long history of supporting unquoted arguments.
But this tends to come as a surprise to new users and sometimes creates
subtly invalid configurations. Let's add some text covering this.
This can be backported to 2.4.
Define a new QUIC congestion algorithm token 'cubic-pacing' for
quic-cc-algo bind keyword. This is identical to default cubic
implementation, except that pacing is used for STREAM frames emission.
This algorithm supports an extra argument to specify a burst size. This
is stored into a new bind_conf member named quic_pacing_burst which can
be reuse to initialize quic path.
Pacing support is still considered experimental. As such, 'cubic-pacing'
can only be used with expose-experimental-directives set.
Modify quic-cc-algo for better extensability of optional parameters
parsing. This will be useful to support a new parameter for maximum
allowed pacing burst size.
Take this opportunity to refine quic-cc-algo documentation. Optional
parameters are now presented as a list which would be soon extended.
Rename 'tune.quic.frontend.max-window-size' with the prefix 'default-'.
This highlights the fact that it is not a hard limit, as it can be
overriden if specifying an optional window size via quic-cc-algo on a
bind line.
No need to backport as this keyword was added on the current dev
version.
414-Uri-Too-Long and 431-Request-Header-Fields-Too-Large are now part of
supported status codes that can be define as error files. The hash table
defined in http_get_status_idx() was updated accordingly.
Historically, an agent-check program is only able to set a proportial weight
to the initial server's weight. However, it could be handy to also set an
absolute value. It is the purpose of this patch.
Instead of changing the current way to set a server's weight, a new
agent-check command is introduced. The string "weight:", followed by an
positive interger or a positive interger percentage, can now be used. If the
value ends with the '%' sign, then the new weight will be proportional to
the initially weight of the server. Otherwise, the value is considered as an
absolute weight and must be between 0 and 256.
This patch should fix the issue #360.
It is now possible to use a log-format string to define the "Set-Cookie"
header value of a response generated by a redirect rule. There is no special
check on the result format and it is not possible during the configuration
parsing. It is proably not a big deal because already existing "set-cookie"
and "clear-cookie" options don't perform any check.
Here is an example:
http-request redirect location https://someurl.com/ set-cookie haproxy="%[var(txn.var)]"
This patch should fix the issue #1784.
On prefix-based redirect, there is an option to drop the query-string of the
location. Here it is the opposite. an option is added to preserve the
query-string of the original URI for a localtion-based redirect.
By setting "keep-query" option, for a location-based redirect only, the
query-string of the original URI is appended to the location. If there is no
query-string, nothing is added (no empty '?'). If there is already a
non-empty query-string on the localtion, the original one is appended with
'&' separator.
This patch should fix issue #2728.
Till now this value was parsed as raw integer using atol() and would
silently ignore any trailing suffix, causing unexpected behaviors when
set, e.g. to "4k". Let's make use of parse_size_err() on it so that
units are supported. This requires to turn it to uint as well, which
was verified to be OK.

units are supported. This requires to turn them to uint as well, which
is OK.
Till now these values were parsed as raw integer using atol() and would
silently ignore any trailing suffix, causing unexpected behaviors when
set, e.g. to "512k". Let's make use of parse_size_err() on them so that
units are supported. This requires to turn them to uint as well, which
is OK.
Sometimes conditions to decide of an anomaly are not as easy to define
as just an error or a success. One example use case would be to monitor
the transfer time and fix a threshold.
An idea suggested by Tristan would be to make permit the "when"
converter to refer to a more variable or dynamic condition.
Here we make this possible by making "when" rely on a named ACL. The
ACL then needs to be specified in either the proxy or the defaults
section. Since it is evaluated inline, it may even refer to information
available at the end (at log time) such as the data transfer time. If
the ACL evalutates to true, the converter passes the data.
Example: log "dbg={-}" when fine, or "dbg={... debug info ...}" on slow
transfers:
acl slow_xfer res.timer.data ge 10000 # more than 10s is slow
log-format "$HAPROXY_HTTP_LOG_FMT \
fsdbg={%[fs.debug_str,when(acl,slow_xfer)]} \
bsdbg={%[bs.debug_str,when(acl,slow_xfer)]}"

The warn-blocked-traffic-after can be significantly lowered. In any
case, in order to be usable it must be well below the limit to have a
chance to emit exploitable traces before the watchdog finally fires.
Even configured at 1ms it looks very difficult to trigger it on a
laptop doing SSL and compression, so applying a 100-fold factor to
cover for large configs and small machines sounds sane for 3.1. In any
case, even at 100ms, the service degradation becomes quite visible.
These functions return a symbolic error code such as ECONNRESET to keep
logs compact while making them human-readable. It's a good alternative
to the numeric code in that it's more expressive, and a good one to the
full message since it's shorter and more precise (some codes even match
errno names).
The doc was updated so that the symbolic names appear in the table. It
could be useful to backport this feature to help with troubleshooting
some issues, though backporting the doc might possibly be more annoying
in case users have local patches already, so maybe the table update does
not need to be backported in this case.
While we get reports of connection setup errors in fc_err/bc_err, we
don't have the equivalent for the recv/send/splice syscalls. Let's
add provisions for new codes that cover the common errno values that
recv/send/splice can return, i.e. ECONNREFUSED, ENOMEM, EBADF, EFAULT,
EINVAL, ENOTCONN, ENOTSOCK, ENOBUFS, EPIPE. We also add a special case
for when the poller reported the error itself. It's worth noting that
EBADF/EFAULT/EINVAL will generally indicate serious bugs in the code
and should not be reported.
The only thing is that it's quite hard to forcefully (and reliably)
trigger these errors in automated tests as the timing is critical.
Using iptables to manually reset established connections in the
middle of large transfers at least permits to see some ECONNRESET
and/or EPIPE, but the other ones are harder to trigger.
