This adds the necessary flags to permit run-time enabling/disabling of
memory profiling. For now this is disabled.
A few words were added to the management doc about it and recalling that
this is limited to certain OSes.

By passing a version number to "add map/acl", it becomes possible to
atomically replace maps and ACLs. The principle is that a new version
number is first retrieved by calling"prepare map/acl", and this version
number is used with "add map" and "add acl". Newly added entries then
remain invisible to the matching mechanism but are visible in "show
map/acl" when the version number is specified, or may be cleard with
"clear map/acl". Finally when the insertion is complete, a
"commit map/acl" command must be issued, and the version is atomically
updated so that there is no intermediate state with incomplete entries.
The command is used to atomically replace a map/acl with the pending
contents of the designated version. The new version must have been
allocated by "prepare map/acl" prior to this. At the moment it is not
possible to force the version when adding new entries, so this may only
be used to atomically clear an ACL/map.
This command allocates a new version for the map/acl, that will be usable
later to prepare the addition of new values to atomically replace existing
ones. Technically speaking the operation consists in atomically incrementing
the next version. There's no "undo" operation here, if a version is not
committed, it will automatically be trashed when committing a newer version.
This will ease maintenance of versionned maps by allowing to clear old or
failed updates instead of the current version. Nothing was done to allow
clearing everyhing, though if there was a need for this, implementing "@all"
or something equivalent wouldn't require more than 3 lines of code.
The maps and ACLs internally all have two versions, the "current" one,
which is the one being matched against, and the "next" one, the one being
filled during an atomic replacement. Till now the "show" commands only used
to show the current one but it can be convenient to be able to show other
ones as well, so let's add the ability to do this with "show map" and
"show acl". The method used here consists in passing the version number
as "@<ver>" before the map/acl name or ID. It would have been better after
it but that could create confusion with keys already using such a format.
Commit b8bd1ee89 ("MEDIUM: cli: add a new experimental "set var" command")
added "get var" and "set var" but "set var" was misplaced in the doc,
breaking the alphabetic ordering.
The text mentionned that only backends with consistent hash method were
supported for dynamic servers. In fact, it is only required that the lb
algorith is dynamic.
By default haproxy loads all files designated by a relative path from the
location the process is started in. In some circumstances it might be
desirable to force all relative paths to start from a different location
just as if the process was started from such locations. This is what this
directive is made for. Technically it will perform a temporary chdir() to
the designated location while processing each configuration file, and will
return to the original directory after processing each file. It takes an
argument indicating the policy to use when loading files whose path does
not start with a slash ('/').
A few options are offered, "current" (the default), "config" (files
relative to config file's dir), "parent" (files relative to config file's
parent dir), and "origin" with an absolute path.
This should address issue #1198.
The alternative arguments are always in curly brackets, let's fix it for
set-timeout.
The Example in set-timeout does not have the one of the required argument.
This commit makes the PR https://github.com/cbonte/haproxy-dconv/pull/34
obsolete.

Render numa detection optional with a global configuration statement
'no numa-cpu-mapping'. This can be used if the applied affinity of the
algorithm is not optimal. Also complete the documentation with this new
keyword.
Use the platform independent type hap_cpuset for the cpu-map statement
parsing. This allow to address CPU index greater than LONGBITS.
Update the documentation to reflect the removal of this limit except for
platforms without cpu_set_t type or equivalent.
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'.
As previously mentioned SPOA code has nothing to do in the haproxy core
since they're not dependent on haproxy's version. This one was moved to
its own repository here with complete history:
https://github.com/haproxy/spoa-example
The current "ADD" vs "ADDQ" is confusing because when thinking in terms
of appending at the end of a list, "ADD" naturally comes to mind, but
here it does the opposite, it inserts. Several times already it's been
incorrectly used where ADDQ was expected, the latest of which was a
fortunate accident explained in 6fa922562 ("CLEANUP: stream: explain
why we queue the stream at the head of the server list").
Let's use more explicit (but slightly longer) names now:
LIST_ADD -> LIST_INSERT
LIST_ADDQ -> LIST_APPEND
LIST_ADDED -> LIST_INLIST
LIST_DEL -> LIST_DELETE
The same is true for MT_LISTs, including their "TRY" variant.
LIST_DEL_INIT keeps its short name to encourage to use it instead of the
lazier LIST_DELETE which is often less safe.
The change is large (~674 non-comment entries) but is mechanical enough
to remain safe. No permutation was performed, so any out-of-tree code
can easily map older names to new ones.
The list doc was updated.
This patch adds an introduction to the http-request normalize-uri section,
explaining what to expect from the normalizers and possible issues that might
arise when not being careful.
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.
This patch adds 4 new sample fetches to get the source and the destination
info (ip address and port) of the backend connection :
* bc_dst : Returns the destination address of the backend connection
* bc_dst_port : Returns the destination port of the backend connection
* bc_src : Returns the source address of the backend connection
* bc_src_port : Returns the source port of the backend connection
The configuration manual was updated accordingly.
The CLI's "set ssl cert" command only works on frontend certificates but
the documentation did not specify this limitations yet.
This patch can be backported to all stable branches.
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

This commit adds the new fields added to the ckch_inst structure in
order to manage the backend certificate hot update (GitHub #427) and the
bug of the default certificate update (GitHub #1143).

This patch re-works configuration parsing, it removes the "server"
lines from "resolvers" sections introduced in commit 56fc5d9eb:
MEDIUM: resolvers: add supports of TCP nameservers in resolvers.
It also extends the nameserver lines to support stream server
addresses such as:
resolvers
nameserver localhost tcp@127.0.0.1:53
Doing so, a part of nameserver's init code was factorized in
function 'parse_resolvers' and removed from 'post_parse_resolvers'.
An explicit stream address prefix such as "tcp6@" "tcp4@"
"stream+ipv6@" "stream+ipv4@" or "stream+unix@" will
allocate an implicit ring buffer with a forward server
targeting the given address.
This is usefull to simply send logs to a log server in tcp
and It doesn't need to declare a ring section in configuration.
Since the internal function str2sa_range is used to addresses
for different objects ('server', 'bind' but also 'log' or
'nameserver') we notice that some combinations are missing.
"ip@" is introduced to authorize the prefix "dgram+ip@" or
"stream+ip@" which dectects automatically IP version but
specify dgram or stream.
"tcp@" was introduced and is an alias for "stream+ip@".
"tcp6" and "tcp4" are now aliases for "stream+ipv6@" and
"stream+ipv4@".
"uxst@" and "uxdg@" are now aliases for "stream+unix@" and
"dgram+unix@".
This patch also adds a complete section in documentation to
describe adresses and their prefixes.
HTTP_2.0 predefined macro returns true for HTTP/2 requests. HTTP/2 doen't
convey a version information, so this macro may seem a bit strange. But for
compatiblity reasons, internally, the "HTTP/2.0" version is set. Thus, it is
handy to rely on it to differenciate HTTP/1 and HTTP/2 requests.
Some predefined ACLs were still based on deprecated sample fetches, like
req_proto_http or req_ver. Now, they use non-deprecated sample fetches. In
addition, the usage lines in the configuration manual have been updated to
be more explicit.

- DOC: clarify that compression works for HTTP/2
This patch clarifies that compression also works with HTTP/2. I have
picked the wording "HTTP/1.1 or above" because it is already used
elsewhere in the documentation.
I have tested that compression indeed works in HTTP/2.

This one is the last optional module to build with haproxy, so let's move
it to addons/. It was renamed to "ot" as it was the only one whose USE_*
option did not match the directory name, now this is consistent.
Few changes were required, only the Makefile, and doc were adjusted, as
the directory was already self-contained and relocatable.
Both the source file and the dummy library are now at the same place.
Maybe the build howto could be moved there as well to make things even
cleaner.
The Makefile, MAINTAINERS, doc, and vtest matrix were updated.

The Makefile, MAINTAINERS, doc, github build matrix, coverity checks
and travis CI's build were updated.
