The function dont remove remaineing analysers and dont update response
channel timeout.
The fix is a copy of the behavior of the functions http_apply_redirect_rule()
and stream_int_retnclose().
Tsvetan Tsvetanov reported that the following Lua code fails in
dev2 and dev3 :
function hello(txn)
local request_msg = txn.req:dup()
local tsm_sock = core.tcp()
tsm_sock:connect("127.0.0.1", 7777)
local res = tsm_sock:send(request_msg)
local response = tsm_sock:receive('*l')
txn.res:send(response)
txn:close()
end
Thierry diagnosed that it was caused by commit 563cc37 ("MAJOR: stream:
use a regular ->update for all stream interfaces"). It broke lua's
ability to establish outgoing connections.
The reason is that the applet used to be notified about established
connections just after the stream analyser loop, and that's not the
case anymore. In peers, this issue didn't happen because peers use
a handshake so after sending data, the response is received and wakes
the applet up again. Here we have to indicate that we want to send or
receive data, this will cause the notification to happen as soon as
the connection is ready. This is similar to pretending that we're
working on a full buffer after all. In theory subscribing for reads
is not needed, but it's added here for completeness.

The table definition message id was used instead of the update acknowledgement id.
This bug causes a malformated message and a protocol error and breaks the
connection.
After that, the updates remain unacknowledged.
This was the first transparent proxy technology supported by haproxy
circa 2005 but it was obsoleted in 2007 by Tproxy 4.0 which removed a
lot of the earlier versions' shortcomings and was finally merged into
the kernel. Since nobody has been using cttproxy for many years now
and nobody has even just tried to compile the files, it's time to
remove it. The doc was updated as well.
This patch removes the special stick tables types names and
use the standard sample type names. This avoid the maintainance
of two types and remove the switch/case for matching a sample
type for each stick table type.
This patch is the first step for sample integration. Actually
the stick tables uses her own data type, and some converters
must be called to convert sample type to stick-tables types.
This patch removes the stick-table types and replace it by
the sample types. This prevent:
- Maintenance of two types of converters
- reduce the code using the samples converters
Now the prototype for each action from each section are the same, and
a discriminant for determining for each section we are called are added.
So, this patch removes the wrappers for the action functions called from
more than one section.
This patch removes 132 lines of useless code.
This patch normalize the return code of the configuration parsers. Before
these changes, the tcp action parser returned -1 if fail and 0 for the
succes. The http action returned 0 if fail and 1 if succes.
The normalisation does:
- ACT_RET_PRS_OK for succes
- ACT_RET_PRS_ERR for failure
Each (http|tcp)-(request|response) action use the same method
for looking up the action keyword during the cofiguration parsing.
This patch mutualize the code.
This patch merges the conguration keyword struct. Each declared configuration
keyword struct are similar with the others. This patch simplify the code.
Action function can return 3 status:
- error if the action encounter fatal error (like out of memory)
- yield if the action must terminate his work later
- continue in other cases
For performances considerations, some actions are not processed by remote
function. They are directly processed by the function. Some of these actions
does the same things but for different processing part (request / response).
This patch give the same name for the same actions, and change the normalization
of the other actions names.
This patch is ONLY a rename, it doesn't modify the code.
This patch group the action name in one file. Some action are called
many times and need an action embedded in the action caller. The main
goal is to have only one header file grouping all definitions.
This mark permit to detect if the action tag is over the allowed range.
- Normally, this case doesn't appear
- If it appears, it is processed by ded fault case of the switch
This patch removes the generic opaque type for storing the configuration of the
acion "set-src" (HTTP_REQ_ACT_SET_SRC), and use the dedicated type "struct expr"
The (http|tcp)-(request|response) action rules use common
opaque type. For the HAProxy embbedded feature, types are know,
it better to add this types in the action union and use it.
The (http|tcp)-(request|response) action rules use common

This patch is the first of a serie which merge all the action structs. The
function "tcp-request content", "tcp-response-content", "http-request" and
"http-response" have the same values and the same process for some defined
actions, but the struct and the prototype of the declared function are
different.
This patch try to unify all of these entries.
A map can store and return various types as output. The only one example is the
IPv4 and IPv6 types. The previous patch remove the type from the sample storage
struct and use the conoverter output type, expecting that all entries of the
map have the same type.
This will be wrong when the maps will support both IPv4 and IPv6 as output.
With the difference between the "struct sample" data and the
"struct sample_storage" data, it was not possible to write
data = data, and we did a memcpy. This patch remove some of
these memcpy.
I can't test this patch because the avalaible 51degrees library is
"51Degrees-C-3.1.5.2" and HAProxy obviously build with another version
(some defines and symbols disappear).
This patch is provided as-is in best effort.
The union name "data" is a little bit heavy while we read the source
code because we can read "data.data.sint". The rename from "data" to "u"
makes the read easiest like "data.u.sint".
This extract is not really required, but it maybe will be usefull later.
A comming soonpatch about simplification of stick table values will
use this union
This patch remove the struct information stored both in the struct
sample_data and in the striuct sample. Now, only thestruct sample_data
contains data, and the struct sample use the struct sample_data for storing
his own data.
This is an introduction to present HAProxy. The aim is to get rid of the
totally obsolete haproxy-en and haproxy-fr files. This file references
another one which is not there yet and which should cover the remaining
part of these obsolete files, which is how to manage the process. The
format is the same as the other docs so it should integrate seamlessly
to existing docs.
