MEDIUM: log: add a new "raw" format
This format is pretty similar to the previous "short" format except that it also removes the severity level. Thus only the raw message is sent. This is suitable for use in containers, where only the raw information is expected and where the severity is supposed to come from the file descriptor used. |

MEDIUM: log: support a new "short" format
This format is meant to be used with local file descriptors. It emits
messages only prefixed with a level, removing all the process name,
system name, date and so on. It is similar to the printk() format used
on Linux. It's suitable to be sent to a local logger compatible with
systemd's output format.
Note that the facility is still required but not used, hence it is
suggested to use "daemon" to remind that it's a local logger.
Example :
log stdout format short daemon # send everything to stdout
log stderr format short daemon notice # send important events to stderr

MEDIUM: log: add support for logging to existing file descriptors
In certain situations it would be desirable to log to an existing file descriptor, the most common case being a pipe between containers or processes. The main issue with pipes is that using write() on them will randomly truncate messages. But there is a trick. By using writev(), we can atomically deliver or drop a message, which perfectly fits the purpose. The only caveat is that large messages (4096 bytes on modern operating systems) may be interleaved with messages from other processes if using nbproc for example. In practice such messages are rare and most of the time when users need such type of logging, the load is low enough for a single process to be running so this is not really a problem. This logging method thus uses unbuffered writev() calls and is uses more CPU than if it used its own buffer with large writes at once, though this is not a problem for moderate loads. Logging to a file descriptor attached to a file also works with the side effect that the process is significantly slowed down during disk accesses and that it's not possible to rotate the file without restarting the process. For this reason this option is not offered as a configuration option, since it would confuse most users, but one could decide to redirect haproxy's output to a file during debugging sessions. Two aliases "stdout" and "stderr" are provided, but keep in mind that these are closed by default in daemon mode. When logging to a pipe or socket at a high enough rate, some logs will be dropped and the number of dropped messages is reported in "show info". |

DOC: logs: the format directive was missing from the second log part
The "log" statement appears both in the global section and in listeners. The "format" directive was only documented in the first one. Maybe we should think about moving this definition to the log section by now. |

DOC: split the http-request actions in their own section
Since http-request was first introduced, more and more actions have been added over time. This makes the "http-request" difficult to read and some actions were forgotten in the list. This is an attempt to make the documenation cleaner. In future steps, it would be great to provide at least one example for each action. |

BUG/MINOR: only auto-prefer last server if lb-alg is non-deterministic
While "option prefer-last-server" only applies to non-deterministic load balancing algorithms, 401/407 responses actually caused haproxy to prefer the last server unconditionally. As this breaks deterministic load balancing algorithms like uri, this patch applies the same condition here. Should be backported to 1.8 (together with "BUG/MINOR: only mark connections private if NTLM is detected"). |

BUG/MINOR: only mark connections private if NTLM is detected
Instead of marking all connections that see a 401/407 response private (for connection reuse), this patch detects a RFC4559/NTLM authentication scheme and restricts the private setting to those connections. This is so we can reuse connections with 401/407 responses with deterministic load balancing algorithms later (which requires another fix). This fixes the problem reported here by Elliot Barlas : https://discourse.haproxy.org/t/unable-to-configure-load-balancing-per-request-over-persistent-connection/3144 Should be backported to 1.8. |

MINOR: pools: allocate most memory pools from an array
For caching it will be convenient to have indexes associated with pools, without having to dereference the pool itself. One solution could consist in replacing all pool pointers with integers but this would limit the number of allocatable pools. Instead here we allocate the 32 first pools from a pre-allocated array whose base address is known so that it's trivial to convert a pool to an index in this array. Pools that cannot fit there will be allocated normally. |

MINOR: http: Use same flag for httpclose and forceclose options
Since keep-alive mode is the default mode, the passive close has disappeared, and in the code, httpclose and forceclose options are handled the same way: connections with the client and the server are closed as soon as the request and the response are received and missing "Connection: close" header is added in each direction. So to make things clearer, forceclose is now an alias for httpclose. And httpclose is explicitly an active close. So the old passive close does not exist anymore. Internally, the flag PR_O_HTTP_PCL has been removed and PR_O_HTTP_FCL has been replaced by PR_O_HTTP_CLO. In HTTP analyzers, the checks done to find the right mode to use, depending on proxies options and "Connection: " header value, have been simplified. This should only be a cleanup and no changes are expected. |

MEDIUM: http: Ignore http-tunnel option on backend
This option is frontends specific, so there is no reason to support it on backends. So now, it is ignored if it is set on a backend and a warning is emitted during the startup. The change is quite trivial, but the commit is tagged as MEDIUM because it is a small breakage with previous versions and configurations using this options could emit a warning now. |

MEDIUM: ssl: add support for ciphersuites option for TLSv1.3
OpenSSL released support for TLSv1.3. It also added a separate function SSL_CTX_set_ciphersuites that is used to set the ciphers used in the TLS 1.3 handshake. This change adds support for that new configuration option by adding a ciphersuites configuration variable that works essentially the same as the existing ciphers setting. Note that it should likely be backported to 1.8 in order to ease usage of the now released openssl-1.1.1. |

MEDIUM: lua: Add stick table support for Lua.
This ads support for accessing stick tables from Lua. The supported operations are reading general table info, lookup by string/IP key, and dumping the table. Similar to "show table", a data filter is available during dump, and as an improvement over "show table" it's possible to use up to 4 filter expressions instead of just one (with implicit AND clause binding the expressions). Dumping with/without filters can take a long time for large tables, and should be used sparingly. |

MEDIUM: protocol: sockpair protocol
This protocol is based on the uxst one, but it uses socketpair and FD passing insteads of a connect()/accept(). The "sockpair@" prefix has been implemented for both bind and server keywords. When HAProxy wants to connect through a sockpair@, it creates 2 new sockets using the socketpair() syscall and pass one of the socket through the FD specified on the server line. On the bind side, haproxy will receive the FD, and will use it like it was the FD of an accept() syscall. This protocol was designed for internal communication within HAProxy between the master and the workers, but it's possible to use it externaly with a wrapper and pass the FD through environment variabls. |

BUG/MEDIUM: session: fix reporting of handshake processing time in the logs
The handshake processing time used to be stored per stream, which was valid when there was exactly one stream per session. With H2 and multiplexing it's not the case anymore and the reported handshake times are wrong in the logs as it's computed between the TCP accept() and the stream creation. Let's first move the handshake where it belongs, which is the session. However, this is not enough because we don't want to report an excessive idle time either for H2 (since many requests use the connection). So the solution used here is to have the stream retrieve sess->tv_accept and the handshake duration when the stream is created, and let the mux immediately reset them. This way, the handshake time becomes zero for the second and subsequent requests in H2 (which was already the case in H1), and the idle time exactly counts how long the connection remained unused while it could be used, so in H1 it runs from the end of the previous response and in H2 it runs from the end of the previous request since the channel is already available. This patch will need to be backported to 1.8. |

BUG/MEDIUM: dns/server: fix incomatibility between SRV resolution and server state file
Server state file has no indication that a server is currently managed by a DNS SRV resolution. And thus, both feature (DNS SRV resolution and server state), when used together, does not provide the expected behavior: a smooth experience... This patch introduce the "SRV record name" in the server state file and loads and applies it if found and wherever required. This patch applies to haproxy-dev branch only. For backport, a specific patch is provided for 1.8. |

REGTEST/MINOR: Missing mandatory "ignore_unknown_macro".
Since bbc34e2 varnish commit (for varnishtest), a new "cli" macro is automatically created for each VTC script to dialog with the CLI. Consequently, as this macro is unknown from higher level code for varnishtest, it makes the scripts fail if we we do not ask varnishtest to disregard the unknown macros. To prevent this, from now on, for each VTC file for haproxy we MUST add "feature ignore_unknown_macro" line to do so. This is mandatory |

MAJOR: chunks: replace struct chunk with struct buffer
Now all the code used to manipulate chunks uses a struct buffer instead. The functions are still called "chunk*", and some of them will progressively move to the generic buffer handling code as they are cleaned up. |
