MEDIUM: mworker: wait mode use standard init code path
The mworker waitpid mode (which is used when a reload failed to apply
the new configuration) was still using a specific initialisation path.
That's a problem since we use a polling loop in the master now, the
master proxy is not initialized and the master CLI is not activated.
This patch removes the initialisation code of the wait mode and
introduce the MODE_MWORKER_WAIT in order to use the same init path as
the MODE_MWORKER with some exceptions. It allows to use the master proxy
and the master CLI during the waitpid mode.
BUG/MINOR: config: Be aware of the HTX during the check of mux protocols
Because the HTX is still experimental, we must add special cases during the
configuration check to be sure it is not enabled on a proxy with incompatible
options. Here, for HTX proxies, when a mux protocol is specified on a bind line
or a server line, we must force the HTX mode (PROTO_MODE_HTX).
Concretely, H2 is the only mux protocol that can be forced. And it doesn't yet
support the HTX. So forcing the H2 on an HTX proxy will always fail.
MINOR: stream-int: remove useless checks on CS and conn flags in si_cs_send()
In si_cs_send(), some checks are done the CS flags en the connection flags
before calling snd_buf(). But these checks are useless because they have already
been done earlier in the function. The harder to figure out is the flag
CO_FL_SOCK_WR_SH. So it is now tested with CF_SHUTW at the beginning.
BUG/MINOR: stream-int: Don't call snd_buf() if there are still data in the pipe
In si_cs_send, as said in comments, snd_buf() should only be called if there is
no data in the pipe anymore. But actually, this condition was not respected.
MINOR: stream-int: Notify caller when an error is reported after a rcv_buf()
For the same reason than for the commit b46784b1c ("MINOR: stream-int: Notify
caller when an error is reported after a rcv_pipe()"), we return 1 after the
call to rcv_buf() in si_cs_send() to notify the caller some processing may be
triggered.
This patch is not flagged as a bug because no strange behaviour was yet observed
without it. It is just a proactive fix to be consistent.
MINOR: stream-int: Notify caller when an error is reported after a rcv_pipe()
In si_cs_send(), when an error is found on the CS or the connection at the
beginning of the function, we return 1 to notify the caller some processing may
be triggered. So, it seems logical to do the same after the call to rcv_pipe().
This patch is not flagged as a bug because no strange behaviour was yet observed
without it. It is just a proactive fix to be consistent.
BUG/MINOR: stats/htx: Remove channel's output when the request is eaten
The request is eaten when the stats applet have finished to send its
response. It was removed from the channel's buffer, removing all HTX blocks till
the EOM. But the channel's output was not reset, leaving the request channel in
an undefined state.
BUG/MEDIUM: mux-h1: Don't set the flag CS_FL_RCV_MORE when nothing was parsed
When we start to parse a new message, if all headers have not been received,
nothing is copied in the channel's buffer. In this situation, we must not set
the flag CS_FL_RCV_MORE on the conn-stream. If we do so, the connection freezes
because there is no data to send that can reenable the reads
BUG/MEDIUM: mux-h1: Fix freeze when the kernel splicing is used
First of all, we need to be sure to keep the flag H1S_F_BUF_FLUSH on the H1S
reading data until all data was flushed from the buffer. Then we need to know
when the kernel splicing is in use and when it ends. This is handled with the
new flag H1S_F_SPLICED_DATA.
Then, we must subscribe to send when some data remain in the pipe after a
snd_pipe(). It is mandatory to wakeup the stream and avoid a freeze.
Finally, we must be sure to update the message state when we restart to use the
channel's buffer. Among other things, it is mandatory to swith the message from
DATA to DONE state when all data were sent using the kernel splicing.
BUG/MINOR: mux-h1: Enable keep-alive on server side
Don't force the close on server side anymore. Since commit 7c6f8b146 ("MAJOR:
connections: Detach connections from streams"), it is possible to release a
stream without the underlying connection.
Because of this change, we must be sure to create a new stream to handle the
next HTTP transaction only on the client side. And we must be sure to correctly
handle the read0 event in h1_recv, to be sure to call h1_process().
MAJOR: mux-h1: Remove the rxbuf and decode HTTP messages in channel's buffer
It avoids a copy between the rxbuf and the channel's buffer. It means the
parsing is done in h1_rcv_buf(). So we need to have a stream to start the
parsing. This change should improve the overall performances. It also implies a
better split between the connection layer and the applicative layer. Now, on the
connection layer, only raw data are manipulated. Raw data received from the
socket are stored in ibuf and those sent are get from obuf. On the applicative
layer, data in ibuf are parsed and copied into the channel's buffer. And on the
other side, those structured data are formatted and copied into obuf.

BUG/MEDIUM: hpack: fix encoding of "accept-ranges" field
James Brown reported that when an "accept-ranges" header field is sent

CLEANUP: fix typos in reg-tests
Fix typos in comments and error messages of reg-tests. Note that this
has not been qualified as minor as it is used for testing purposes, not
end-users.
MINOR: lua/htx: Forbid lua usage when the HTX is enabled on a proxy
For now, the lua scripts are not compatible with the new HTX internal
representation of HTTP messages. Thus, for a given proxy, when the option
"http-use-htx" is enabled, an error is triggered if any lua's
action/service/sample-fetch/converter is also configured.
MINOR: filters/htx: Forbid filters when the HTX is enabled on a proxy
For now, the filters are not compatible with the new HTX internal representation
of HTTP messages. Thus, for a given proxy, when the option "http-use-htx" is
enabled, an error is triggered if any filter is also configured.
MEDIUM: mux-h1: Handle errors and timeouts in the stream
To do so, the stream is created as earlier as possible. It means, during the mux
creation for the first request, and for others, just at the end of the previous
transaction. Because all timeouts are handled by the strream, the mux's task is
now useless, so it is removed. Finally, to report errors, flags are set on the
HTX message. The HTX message is passed to the stream if there is some content to
analyse or if there is some error to handle.
All of this will probably be reworked later to handle errors and timeouts
directly in the mux. For now, it is the simpler way to handle all of this.
MEDIUM: mux-h1: Wait for connection establishment before consuming channel's data
When a server is down, the channel's data must not be consumed. This is
required to allow redispatch and connection retry. So now, we wait for
the connection to be marked as connected, with the flag CO_FL_CONNECTED,
before starting to consume channel's data. In the mux, this event is
tracked with the flag H1C_F_CS_WAIT_CONN.
It does the same than smp_prefetch_http but for HTX messages. It can be called
from an HTTP proxy or a TCP proxy. For HTTP proxies, the parsing is handled by
the mux, so it does nothing but wait. For TCP proxies, it tries to parse an HTTP
message and to convert it in a temporary HTX message. Sample fetches will use
this temporary variable to do their job.
MEDIUM: proto_htx: Adapt htx_wait_for_request_body to handle HTX messages
This version is simpler than the legacy one because the parsing is no more
handled by the analyzer. So now we just need to wait to have more data to move
on.
MINOR: proto_htx: Add functions to handle the stats applet
For now, the call to the stats applet is disabled for HTX messages. But HTX
versions of the function to check the request URI against the stats URI and the
fnuction to prepare the call to the stats applet have been added.
It is more or less the same than legacy version but adapted to be called from
HTX analyzers. In the legacy version of this function, we switch on the HTX code
when applicable.

MINOR: proto_htx: Add the internal function htx_del_hdr_value
It is more or less the same than del_hdr_value but adapted to be called from HTX
analyzers. The main changes is that it takes pointers on the start and the end
of the header value.
MAJOR: mux-h1/proto_htx: Switch mux-h1 and HTX analyzers on the HTX representation
The mux-h1 now parses and formats HTTP/1 messages using the HTX
representation. The HTX analyzers have been updated too. For now, only
htx_wait_for_{request/response} and http_{request/response}_forward_body have
been adapted. Others are disabled for now.
Now, the HTTP messages are parsed by the mux on a side and then, after analysis,
formatted on the other side. In the middle, in the stream, there is no more
parsing. Among other things, the version parsing is now handled by the
mux. During the data forwarding, depending the value of the "extra" field, we
are able to know if the body length is known or not and if yes, how many bytes
are still expected.
MINOR: http_htx: Add functions to manipulate HTX messages in http_htx.c
This file will host all functions to manipulate HTTP messages using the HTX
representation. Functions in this file will be able to be called from anywhere
and are mainly related to the HTTP semantics.
MEDIUM: htx: Add API to deal with the internal representation of HTTP messages
The internal representation of an HTTP message, called HTX, is a structured
representation, unlike the old one which is a raw representation of
messages. Idea is to have a version-agnostic representation of the HTTP
messages, which can be easily used by to handle HTTP/1, HTTP/2 and hopefully
QUIC messages, and communication from one of them to another.
In this patch, we add types to define the internal representation itself and the
main functions to manipulate them.
MEDIUM: mux-h1: Add support of the kernel TCP splicing to forward data
The mux relies on the flag CO_RFL_BUF_FLUSH during a call to h1_rcv_buf to know
if it needs to stop reads and to flush its internal buffers to use kernel tcp
splicing. It is the caller responsibility (here the SI) to know when it must
come back on buffered exchanges.
MAJOR: mux-h1/proto_htx: Handle keep-alive connections in the mux
Now, the connection mode is detected in the mux and not in HTX analyzers
anymore. Keep-alive connections are now managed by the mux. A new stream is
created for each transaction. This removes the most important part of the
synchronization between channels and the HTTP transaction cleanup. These changes
only affect the HTX part (proto_htx.c). Legacy HTTP analyzers remain untouched
for now.
On the client-side, the mux is responsible to create new streams when a new
request starts. It is also responsible to parse and update the "Connection:"
header of the response. On the server-side, the mux is responsible to parse and
update the "Connection:" header of the request. Muxes on each side are
independent. For now, there is no connection pool on the server-side, so it
always close the server connection.
MEDIUM: mux-h1: Add parsing of incoming and ougoing HTTP messages
For now, it only parses and transfers data. There is no internal representation
yet. It means the stream still need to parse it too. So a message is parsed 3
times today: one time by each muxes (the client one and the server one) and
another time by the stream. This is of course inefficient. But don't worry, it
is only a transitionnal state. And this mux is optional for now.
BTW, headers and body parsing are now handled using same functions than the mux
H2. Request/Response synchronization is also handled. The mux's task is now used
to catch client/http-request timeouts. Others timeouts are still handled by the
stream. On the clien-side, the stream is created once headers are fully parsed
and body parsing starts only when heeaders are transferred to the stream (ie,
copied into channel buffer).
There is still some known limitations here and there. But, it works in the
common cases. Bad message are not captured and some logs are emitted when errors
occur, only if no stream are attached to the mux. Otherwise, data are
transferred and we let the stream handles errors itself.
MEDIUM: mux-h1: Add dummy mux to handle HTTP/1.1 connections
For now, it is just an other kind of passthrough multiplexer, but with internal
buffers to be prepared to parse incoming messages and to format outgoing
ones. There is also a task attached to it to handle timeouts. However, because
it does not handle any timeout for now, this task is unused. And finally,
because it handles internal buffers, it also handles retries on recv/send. To
use this multiplexer, you must use the option "http-use-htx" both on the
frontend and the backend.
It does not support keep-alive and will freeze connections after the first
request/response.
MEDIUM: proto_htx: Add HTX analyzers and use it when the mux H1 is used
For now, these analyzers are just copies of the legacy HTTP analyzers. But,
during the HTTP refactoring, it will be the main place where it will be
visible. And in legacy analyzers, the macro IS_HTX_STRM is used to know if the
HTX version should be called or not.
Note: the following commits were applied to proto_http.c after this patch
was developed and need to be studied to see if an adaptation to htx
is required :
