This provides more consistency between the master and the worker. When
"prompt timed" is passed on the master, the timed mode is toggled. When
enabled, for a master it will show the master process' uptime, and for
a worker it will show this worker's uptime. Example:
master> prompt timed
[0:00:00:50] master> show proc
#<PID> <type> <reloads> <uptime> <version>
11940 master 1 [failed: 0] 0d00h02m10s 2.8-dev11-474c14-21
# workers
11955 worker 0 0d00h00m59s 2.8-dev11-474c14-21
# old workers
11942 worker 1 0d00h02m10s 2.8-dev11-474c14-21
# programs
[0:00:00:58] master> @!11955
[0:00:01:03] 11955> @!11942
[0:00:02:17] 11942> @
[0:00:01:10] master>
Entering "prompt timed" toggles reporting of the process' uptime in
the prompt, which will report days, hours, minutes and seconds since
it was started. As discussed with Tim in issue #2145, this can be
convenient to roughly estimate the time between two outputs, as well
as detecting that a process failed to be reloaded for example.
Add a new output format "oneline" for "show quic" command. This prints
one connection per line with minimal information. The objective is to
have an equivalent of the netstat/ss tools with just enough information
to quickly find connection which are misbehaving.
A legend is printed on the first line to describe the field columns
starting with a dash character.
This should be backported up to 2.7.
Add an extra optional argument for "show quic" to specify desired output
format. Its objective is to control the verbosity per connections. For
the moment, only "full" is supported, which is the already implemented
output with maximum information.
This should be backported up to 2.7.
Depending on what we're debugging, some FDs can represent pollution in
the "show fd" output. Here we add a set of filters allowing to pick (or
exclude) any combination of listener, frontend conn, backend conn, pipes,
etc. "show fd l" will only list listening connections for example.
Starting haproxy with -dL helps enumerate the list of libraries in use.
But sometimes in order to go further we'd like to see their address
ranges. This is already supported on the CLI's "show libs" but not on
the command line where it can sometimes help troubleshoot startup issues.
Let's dump them when in verbose mode. This way it doesn't change the
existing behavior for those trying to enumerate libs to produce an archive.
Using -dMfail alone does nothing unless tune.fail-alloc is set, which
renders it pretty useless as-is, and is not intuitive. Let's change
this so that the filure rate is preset to 1% when the option is set on
the command line. This allows to inject failures without having to edit
the configuration.
The ocsp-related CLI commands tend to work with OCSP_CERTIDs as well as
certificate paths so the path should also be added to the output of the
"show ssl ocsp-response" command when no certid or path is provided.
In order to increase usability, the "show ssl ocsp-response" also takes
a frontend certificate path as parameter. In such a case, it behaves the
same way as "show ssl cert foo.pem.ocsp".
A new format option can be passed to the "show ssl ocsp-response" CLI
command to dump the contents of an OCSP response in base64. This is
needed because thanks to the new OCSP auto update mechanism, we could
end up using an OCSP response internally that was never provided by the
user.
This command can be used to dump information about the entries contained
in the ocsp update tree. It will display one line per concerned OCSP
response and will contain the expected next update time as well as the
time of the last successful update, and the number of successful and
failed attempts.
To prevent data loss for QUIC connections, haproxy global variable jobs
is incremented each time a quic-conn socket is allocated. This allows
the QUIC connection to terminate all its transfer operation during proxy
soft-stop. Without this patch, the process will be terminated without
waiting for QUIC connections.
Note that this is done in qc_alloc_fd(). This means only QUIC connection
with their owned socket will properly support soft-stop. In the other
case, the connection will be interrupted abruptly as before. Similarly,
jobs decrement is conducted in qc_release_fd().
This should be backported up to 2.7.
The -dF option can now be used to disable data fast-forward. It does the
same than the global option "tune.fast-forward off". Some reg-tests may rely
on this optim. To detect the feature and skip such script, the following
vtest command must be used:
feature cmd "$HAPROXY_PROGRAM -cc '!(globa.tune & GTUNE_NO_FAST_FWD)'"
Reduce default "show quic" output by masking connection on
closing/draing state due to a CONNECTION_CLOSE emission/reception. These
connections can still be displayed using the special argument "all".
This should be backported up to 2.7.
Implement a basic "show quic" CLI handler. This command will be useful
to display various information on all the active QUIC frontend
connections.
This work is heavily inspired by "show sess". Most notably, a global
list of quic_conn has been introduced to be able to loop over them. This
list is stored per thread in ha_thread_ctx.
Also add three CLI handlers for "show quic" in order to allocate and
free the command context. The dump handler runs on thread isolation.
Each quic_conn is referenced using a back-ref to handle deletion during
handler yielding.
For the moment, only a list of raw quic_conn pointers is displayed. The
handler will be completed over time with more information as needed.
This should be backported up to 2.7.
The new "update ssl ocsp-response <certfile>" CLI command allows to
update the stored OCSP response for a given certificate. It relies on
the http_client which is used to send an HTTP request to the OCSP
responder whose URI can be extracted from the certificate.
This command won't work for a certificate that did not have a stored
OCSP response yet.
Stick-tables support sharding to multiple peers but there was no way to
know to what shard an entry was going to be sent. Let's display this in
the "show table" output to ease debugging.
The "show pools" command is used a lot for debugging but didn't get much
love over the years. This patch brings new capabilities:
- sorting the output by pool names to ese their finding ("byname").
- sorting the output by reverse item size to spot the biggest ones("bysize")
- sorting the output by reverse number of allocated bytes ("byusage")
The last one (byusage) also omits displaying the ones with zero allocation.
In addition, an optional max number of output entries may be passed so as
to dump only the N most relevant ones.
Correct a commentary in in include/haproxy/global-t.h and include/haproxy/tools.h
Replace the CLI command 'set global-key <key>' by 'set anon global-key <key>' in
order to find it easily when you don't remember it, the recommandation can guide
you when you just tap 'set anon'.
No backport needed, except if anonymization mechanism is backported.
This commit adds a new command line option -dC to dump the configuration
file. An optional key may be appended to -dC in order to produce an
anonymized dump using this key. The anonymizing process uses the same
algorithm as the CLI so that the same key will produce the same hashes
for the same identifiers. This way an admin may share an anonymized
extract of a configuration to match against live dumps. Note that key 0
will not anonymize the output. However, in any case, the configuration
is dumped after tokenizing, thus comments are lost.
In order to allow users to dump internal states using a specific key
without changing the global one, we're introducing a key in the CLI's
appctx. This key is preloaded from the global one when "set anon on"
is used (and if none exists, a random one is assigned). And the key
can optionally be assigned manually for the whole CLI session.
A "show anon" command was also added to show the anon state, and the
current key if the users has sufficient permissions. In addition, a
"debug dev hash" command was added to test the feature.
Add a uint32_t key in global to hash words with it. A new CLI command
'set global-key <key>' was added to change the global anonymizing key.
The global may also be set in the configuration using the global
"anonkey" directive. For now this key is not used.
By default we now dump stats between caller and callee, but by
specifying "aggr" on the command line, stats get aggregated by
callee again as it used to be before the feature was available.
It may sometimes be helpful when comparing total call counts,
though that's about all.
In ticket #1805 an user is impacted by the limitation of size of the CLI
buffer when updating a ca-file.
This patch allows a user to append new certificates to a ca-file instead
of trying to put them all with "set ssl ca-file"
The implementation use a new function ssl_store_dup_cafile_entry() which
duplicates a cafile_entry and its X509_STORE.
ssl_store_load_ca_from_buf() was modified to take an apped parameter so
we could share the function for "set" and "add".
The output of "show activity" can be so large that the output is visually
unreadable on a screen. Let's add an option to filter on the desired
column (actually the thread number), use "0" to report only the first
column (aggregated/sum/avg), and use "-1", the default, for the normal
detailed dump.
Starting from OpenSSLv3, providers are at the core of cryptography
functions. Depending on the provider used, the way the SSL
functionalities work could change. This new 'show ssl providers' CLI
command allows to show what providers were loaded by the SSL library.
This is required because the provider configuration is exclusively done
in the OpenSSL configuration file (/usr/local/ssl/openssl.cnf for
instance).
A new line is also added to the 'haproxy -vv' output containing the same
information.
It's difficult from outside haproxy to detect the supported keywords
and syntax. Interestingly, many of our modern keywords are enumerated
since they're registered from constructors, so it's not very hard to
enumerate most of them.
This patch creates some basic infrastructure to support dumping existing
keywords from different classes on stdout. The format will differ depending
on the classes, but the idea is that the output could easily be passed to
a script that generates some simple syntax highlighting rules, completion
rules for editors, syntax checkers or config parsers.
The principle chosen here is that if "-dK" is passed on the command-line,
at the end of the parsing the registered keywords will be dumped for the
requested classes passed after "-dK". Special name "help" will show known
classes, while "all" will execute all of them. The reason for doing that
after the end of the config processor is that it will also enumerate
internally-generated keywords, Lua or even those loaded from external
code (e.g. if an add-on is loaded using LD_PRELOAD). A typical way to
call this with a valid config would be:
./haproxy -dKall -q -c -f /path/to/config
If there's no config available, feeding /dev/null will also do the job,
though it will not be able to detect dynamically created keywords, of
course.
This patch also updates the management doc.
For now nothing but the help is listed, various subsystems will follow
in subsequent patches.
Dynamic servers feature is now judged to be stable enough. Remove the
experimental-mode requirement for "add/del server" commands. This should
facilitate dynamic servers adoption.
The 9 currently available debugging options may now be checked, set, or
cleared using -dM. The directive now takes a comma-delimited list of
options after the optional poisonning byte. With "help", the list of
available options is displayed with a short help and their current
status.
The management doc was updated.
"mcli-debug-mode on" enables every command that were meant for a worker,
on the CLI of the master. Which mean you can issue, "show fd", show
stat" in order to debug the MASTER proxy.
You can also combine it with "expert-mode on" or "experimental-mode on"
to access to more commands.
