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replacement for the OpenTracing filter since OpenTracing itself is no
longer maintained nor supported: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.
For now, only the H1 multiplexer is able to capture malformed messages. So
it is better to update the management guide accordingly to avoid any
confusion.
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.
Since sd_notify() is now implemented in src/systemd.c, there is no need
anymore to build its support conditionnally with USE_SYSTEMD.
This patch add supports for -Ws for every build and removes the
USE_SYSTEMD build option. It also remove every reference to USE_SYSTEMD
in the documentation and the CI.
This also allows to run the reg-tests in -Ws with the new VTest support.
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.
tasklet_wakeup_on() and its derivates (tasklet_wakeup_after() and
tasklet_wakeup()) do not support passing a wakeup cause like
task_wakeup(). This is essentially due to an API limitation cause by
the fact that for a very long time the only reason for waking up was
to process pending I/O. But with the growing complexity of mux tasks,
it is becoming important to be able to skip certain heavy processing
when not strictly needed.
One possibility is to permit the caller of tasklet_wakeup() to pass
flags like task_wakeup(). Instead of going with a complex naming scheme,
let's simply make the flags optional and be zero when not specified. This
means that tasklet_wakeup_on() now takes either 2 or 3 args, and that the
third one is the optional flags to be passed to the callee. Eligible flags
are essentially the non-persistent ones (TASK_F_UEVT* and TASK_WOKEN_*)
which are cleared when the tasklet is executed. This way the handler
will find them in its <state> argument and will be able to distinguish
various causes for the call.
These are user-defined one-shot events that are application-specific
and reset upon wakeup and were not documented. No backport is needed
since these were added to 3.1.
Contrary to what the doc states, it is not expected (nor relevant) to
use yield-dependent methods such as core.yield() or core.(m)sleep() from
contexts that don't support yielding. Such contexts include body, init,
fetches and converters.
Thus the doc got it wrong since the beginning, because such methods were
never supported from the above contexts, yet it was listed in the list
of compatible contexts (probably the result of a copy-paste), which is
error-prone because it could either cause a Lua runtime error to be
thrown, or be ignored in some other cases.
It should be backported to all stable versions.
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.
"show sess" command now supports a list of options that can be set after all
other possible arguments (<id>, all...). For now, "show-uri" is the only
supported option. With this options, the captured URI, if non-null, is added
to the dump of a stream, complete or now. The URI may be anonymized if
necessary.
This patch should fix the issue #663.
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.

silently ignore any trailing suffix, preventing from starting when set

limit its range to INT_MAX - 2*sizeof(void*), which was previously
partially handled as part of the sign check.

0..INT_MAX.

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)]}"

"debug dev" commands are not meant to be used by end-users, and are
purposely not documented. Yet due to their usefulness in troubleshooting
sessions, users are increasingly invited by developers to use some of
them.
"debug dev counters" is one of them. Better move it to "debug counters"
and document it so that users can check them even if the output can look
cryptic at times. This, combined with DEBUG_GLITCHES, can be convenient
to observe suspcious activity. The doc however precises that the format
may change between versions and that new entries/types might appear
within a stable branch.
The program section is unreliable and should not be used, more reliable
alternatives exist outside HAProxy. Let's depreciate the section so we
could remove it completely in 3.3.
