This one was deprecated in 2.3 and marked for removal in 2.5. It suffers
too many limitations compared to threads, and prevents some improvements
from being engaged. Instead of a bypassable startup error, there is now
a hard error.
The parsing code was removed, and very few obvious cases were as well.
The code is deeply rooted at certain places (e.g. "for" loops iterating
from 0 to nbproc) so it will not be that trivial to remove everywhere.
The "bind" and "bind-process" parsers will have to be adjusted, though
maybe not completely changed if we later want to support thread groups
for large NUMA machines. Some stats socket restrictions were removed,
and the doc was updated according to what was done. A few places in the
doc still refer to nbproc and will have to be revisited. The master-worker
code also refers to the process number to distinguish between master and
workers and will have to be carefully adjusted. The MAX_PROCS macro was
reset to 1, this will at least reduce the size of some remaining arrays.
Two regtests were dependieng on this directive, one with an explicit
"nbproc 1" and another one testing the master's CLI using nbproc 4.
Both were adapted.
The `show ssl ocsp-response` feature is not available with BoringSSL,
but we don't have a way to disable this feature only with boringSSL on
the CI. Disable the reg-test until we do.
This file adds tests for the new "show ssl ocsp-response" command and
the new "show ssl cert foo.pem.ocsp" and "show ssl cert *foo.pem.ocsp"
special cases. They are all used to display information about an OCSP
response, committed or not.
This patch adds the `-cc` (check condition) argument to evaluate conditions on
startup and return the result as the exit code.
As an example this can be used to easily check HAProxy's version in scripts:
haproxy -cc 'version_atleast(2.4)'
This resolves GitHub issue #1246.

Since the commit 5e702fcad ("MINOR: http-ana: Use -1 status for client
aborts during queuing and connect"), -1 status is reported in the log
message when the client aborts during queuing and
connect. http_abortonclose.vtc script must be update accordingly.
This vtc tests the "new ssl crl-file" which allows to create a new empty
CRL file that can then be set through a "set+commit ssl crl-file"
command pair. It also tests the "del ssl crl-file" command which allows
to delete an unused CRL file.
This vtc tests the "new ssl ca-file" which allows to create a new empty
CA file that can then be set through a "set+commit ssl ca-file" command
pair. It also tests the "del ssl ca-file" command which allows to delete
an unused CA file.
This patch adds the "show ssl ca-file [<cafile>[:index]]" CLI command.
This command can be used to display the list of all the known CA files
when no specific file name is specified, or to display the details of a
specific CA file when a name is given. If an index is given as well, the
command will only display the certificate having the specified index in
the CA file (if it exists).
The details displayed for each certificate are the same as the ones
showed when using the "show ssl cert" command on a single certificate.
This fixes a subpart of GitHub issue #1057.
The "abort" command aborts an ongoing transaction started by a "set ssl
ca-file" command. Since the updated CA file data is not pushed into the
cafile tree until a "commit ssl ca-file" call is performed, the abort
command simply clears the new cafile_entry that was stored in the
cafile_transaction.
This fixes a subpart of GitHub issue #1057.
Some regtests involve multiple requests from multiple clients, which can
be dispatched as multiple requests to a server. It turns out that the
idle connection sharing works so well that very quickly few connections
are used, and regularly some of the remaining idle server connections
time out at the moment they were going to be reused, causing those random
"HTTP header incomplete" traces in the logs that make them fail often. In
the end this is only an artefact of the test environment.
And indeed, some tests like normalize-uri which perform a lot of reuse
fail very often, about 20-30% of the times in the CI, and 100% of the
time in local when running 1000 tests in a row. Others like ubase64,
sample_fetches or vary_* fail less often but still a lot in tests.
This patch addresses this by adding "tune.idle-pool.shared off" to all
tests which have at least twice as many requests as clients. It proves
very effective as no single error happens on normalize-uri anymore after
10000 tests. Also 100 full runs of all tests yield no error anymore.
One test is tricky, http_abortonclose, it used to fail ~10 times per
1000 runs and with this workaround still fails once every 1000 runs.
But the test is complex and there's a warning in it mentioning a
possible issue when run in parallel due to a port reuse.
normalize-uri http rule is marked as experimental, so it cannot be
activated without the global 'expose-experimental-directives'. The
associated vtc is updated to be able to use it.
This script test abortonclose option for HTTP/1 client only. It may be
backported as far as 2.0. But on the 2.2 and prior, the syslog part must be
adapted to catch log messages emitted by proxy during HAProxy
startup. Following lines must be added :
recv
expect ~ "[^:\\[ ]\\[${h1_pid}\\]: Proxy fe1 started."
recv
expect ~ "[^:\\[ ]\\[${h1_pid}\\]: Proxy fe2 started."
The map_redirect test already tests for "show map", "del map" and
"clear map" but doesn't have any "add map" command. Let's add some
trivial ones involving one regular entry and two other ones added as
payload, checking they are properly returned.
Error output for dynamic server creation if invalid lb algo has changed
since previous commit :
MINOR: server: fix doc/trace on lb algo for dynamic server creation
The vtest regex should have been updated has well to match it.
This normalizer removes "/./" segments from the path component.
Usually the dot refers to the current directory which renders those segments redundant.
See GitHub Issue #714.
Implement a new CLI command 'del server'. It can be used to removed a
dynamically added server. Only servers in maintenance mode can be
removed, and without pending/active/idle connection on it.
Add a new reg-test for this feature. The scenario of the reg-test need
to first add a dynamic server. It is then deleted and a client is used
to ensure that the server is non joinable.
The management doc is updated with the new command 'del server'.
This patch renames all existing uri-normalizers into a more consistent naming
scheme:
1. The part of the URI that is being touched.
2. The modification being performed as an explicit verb.
This normalizer merges `../` path segments with the predecing segment, removing
both the preceding segment and the `../`.
Empty segments do not receive special treatment. The `merge-slashes` normalizer
should be executed first.
See GitHub Issue #714.
With the json_query can a JSON value be extacted from a header
or body of the request and saved to a variable.
This converter makes it possible to handle some JSON workload
to route requests to different backends.
ub64dec and ub64enc are the base64url equivalent of b64dec and base64
converters. base64url encoding is the "URL and Filename Safe Alphabet"
variant of base64 encoding. It is also used in in JWT (JSON Web Token)
standard.
RFC1421 mention in base64.c file is deprecated so it was replaced with
RFC4648 to which existing converters, base64/b64dec, still apply.
Example:
HAProxy:
http-request return content-type text/plain lf-string %[req.hdr(Authorization),word(2,.),ub64dec]
Client:
Token=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VyIjoiZm9vIiwia2V5IjoiY2hhZTZBaFhhaTZlIn0.5VsVj7mdxVvo1wP5c0dVHnr-S_khnIdFkThqvwukmdg
$ curl -H "Authorization: Bearer ${TOKEN}" http://haproxy.local
{"user":"foo","key":"chae6AhXai6e"}
set_ssl_cert_bundle.vtc requires at least OpenSSL 1.1.0 and we don't
have any way to check this when launching the reg-tests suite.
Mark the reg-test as broken since it will fails on old versions of
openSSL and libreSSL.
This test loads a configuration which uses multi-certificates bundle and
tries to change them over the CLI.
Could be backported as far as 2.2, however the 2.2 version must be
adapted to commit the bundle and not each certificate individually.
set var <name> <expression>
Allows to set or overwrite the process-wide variable 'name' with the result
of expression <expression>. Only process-wide variables may be used, so the
name must begin with 'proc.' otherwise no variable will be set. The
<expression> may only involve "internal" sample fetch keywords and converters
even though the most likely useful ones will be str('something') or int().
Note that the command line parser doesn't know about quotes, so any space in
the expression must be preceeded by a backslash. This command requires levels
"operator" or "admin". This command is only supported on a CLI connection
running in experimental mode (see "experimental-mode on").
Just like for "set-var" in the global section, the command uses a temporary
dummy proxy to create a temporary "set-var(name)" rule to assign the value.
The reg test was updated to verify that an updated global variable is properly
reflected in subsequent HTTP responses.
Process-wide variables can now be displayed from the CLI using "get var"
followed by the variable name. They must all start with "proc." otherwise
they will not be found. The output is very similar to the one of the
debug converter, with a type and value being reported for the embedded
sample.
This command is limited to clients with the level "operator" or higher,
since it can possibly expose traffic-related data.
This reg-test tests "set-var" in the global section, with some overlapping
variables and using a few samples and converters, then at the TCP and HTTP
levels using proc/sess/req variables.
If the first active line of a crt-list file is also the first mentioned
certificate of a frontend that does not have the strict-sni option
enabled, then its certificate will be used as the default one. We then
do not want this instance to be removable since it would make a frontend
lose its default certificate.
Considering that a crt-list file can be used by multiple frontends, and
that its first mentioned certificate can be used as default certificate
for only a subset of those frontends, we do not want the line to be
removable for some frontends and not the others. So if any of the ckch
instances corresponding to a crt-list line is a default instance, the
removal of the crt-list line will be forbidden.
It can be backported as far as 2.2.
The default SSL_CTX used by a specific frontend is the one of the first
ckch instance created for this frontend. If this instance has SNIs, then
the SSL context is linked to the instance through the list of SNIs
contained in it. If the instance does not have any SNIs though, then the
SSL_CTX is only referenced by the bind_conf structure and the instance
itself has no link to it.
When trying to update a certificate used by the default instance through
a cli command, a new version of the default instance was rebuilt but the
default SSL context referenced in the bind_conf structure would not be
changed, resulting in a buggy behavior in which depending on the SNI
used by the client, he could either use the new version of the updated
certificate or the original one.
This patch adds a reference to the default SSL context in the default
ckch instances so that it can be hot swapped during a certificate
update.
This should fix GitHub issue #1143.
It can be backported as far as 2.2.
If an unknown CA file was first mentioned in an "add ssl crt-list" CLI
command, it would result in a call to X509_STORE_load_locations which
performs a disk access which is forbidden during runtime. The same would
happen if a "ca-verify-file" or "crl-file" was specified. This was due
to the fact that the crt-list file parsing and the crt-list related CLI
commands parsing use the same functions.
The patch simply adds a new parameter to all the ssl_bind parsing
functions so that they know if the call is made during init or by the
CLI, and the ssl_store_load_locations function can then reject any new
cafile_entry creation coming from a CLI call.
It can be backported as far as 2.2.
Add an empty expect statement after the 'enable server' cli command.
This ensures that the command has been properly handled by haproxy and
its processing is over.
It should fix the unstable behavior of the test which causes reports of
503 even after the server has been enabled.
This should fix the github issue #1188.
Allow to specify the mux proto for a dynamic server. It must be
compatible with the backend mode to be accepted. The reg-tests has been
extended for this error case.
Write a regtest for the cli command 'add server'. This test will execute
some invalid commands and validates the reported error. A client will
then try to connect to a dynamic server just created and activated.
The recently introduced Financial Information eXchange (FIX)
converters have some hard coded tags based on the specification that
were misspelled. Specifically, SenderComID and TargetComID should
be SenderCompID and TargetCompID according to the specification [1][2].
This patch updates all references, which includes the converters
themselves, the regression test, and the documentation.

Add two new regtests which check the behavior of http-reuse when the
connection target is not a server. More specifically check the dispatch
and transparent backend. In these cases, the behavior should be similar
to http-reuse never mode.
