For now, these addresses are never set. But the idea is to be able to set, at
least first, the client source and destination addresses at the stream level
without updating the session or connection ones.
Of course, because these addresses are carried by the strream-interface, it
would be possible to set server source and destination addresses at this level
too.
Functions to fill these addresses have been added: si_get_src() and
si_get_dst(). If not already set, these functions relies on underlying
layers to fill stream-interface addresses. On the frontend side, the session
addresses are used if set, otherwise the client connection ones are used. On
the backend side, the server connection addresses are used.
And just like for sessions and conncetions, si_src() and si_dst() may be used to
get source and destination addresses or the stream-interface. And, if not set,
same mechanism as above is used.
If the stream-interface is waiting for more buffer room to store incoming
data, it is important at the stream level to stop to wait for more data to
continue. Thanks to the previous patch ("BUG/MEDIUM: stream-int: Notify
stream that the mux wants more room to xfer data"), the stream is woken up
when this happens. In this patch, we take care to interrupt the
corresponding tcp-content ruleset or to stop waiting for the HTTP message
payload.
To ease detection of the state, si_rx_blocked_room() helper function has
been added. It returns non-zero if the stream interface's Rx path is blocked
because of lack of room in the input buffer.
This patch is part of a series related to the issue #1362. It should be
backported as ar as 2.0, probably with some adaptations. So be careful
during backports.
appctx_new() is exclusively called with tid_bit and it only uses the
mask to pass it to the accompanying task. There is no point requiring
the caller to know about a mask there, nor is there any point in
creating an applet outside of the context of its own thread anyway.
Let's drop this and pass tid_bit to task_new() directly.
It's been too short for quite a while now and is now full. It's still
time to extend it to 32-bits since we have room for this without
wasting any space, so we now gained 16 new bits for future flags.
The values were not reassigned just in case there would be a few
hidden u16 or short somewhere in which these flags are placed (as
it used to be the case with stream->pending_events).
The patch is tagged MEDIUM because this required to update the task's
process() prototype to use an int instead of a short, that's quite a
bunch of places.
This callback function was only defined by the mux-h1. But it has been
removed in the previous commit because it is unused now. So, we can do a
step forward removing the callback function from the mux definition and the
cs_info structure.
When a new connection is created, its target is always set just after. So the
connection target may set when it is created instead, during its initialisation
to be precise. It is the purpose of this patch. Now, conn_new() function is
called with the connection target as parameter. The target is then passed to
conn_init(). It means the target must be passed when cs_new() is called. In this
case, the target is only used when the conn-stream is created with no
connection. This only happens for tcpchecks for now.
This patch fixes all the leftovers from the include cleanup campaign. There
were not that many (~400 entries in ~150 files) but it was definitely worth
doing it as it revealed a few duplicates.
This one was not easy because it was embarking many includes with it,
which other files would automatically find. At least global.h, arg.h
and tools.h were identified. 93 total locations were identified, 8
additional includes had to be added.
In the rare files where it was possible to finalize the sorting of
includes by adjusting only one or two extra lines, it was done. But
all files would need to be rechecked and cleaned up now.
It was the last set of files in types/ and proto/ and these directories
must not be reused anymore.
