Multiple pipelines and limiting the number of connections.

Browse Source 
Introducing a number of options to the multi interface that
allows for multiple pipelines to the same host, in order to
optimize the balance between the penalty for opening new
connections and the potential pipelining latency.

Two new options for limiting the number of connections:

CURLMOPT_MAX_HOST_CONNECTIONS - Limits the number of running connections
to the same host. When adding a handle that exceeds this limit,
that handle will be put in a pending state until another handle is
finished, so we can reuse the connection.

CURLMOPT_MAX_TOTAL_CONNECTIONS - Limits the number of connections in total.
When adding a handle that exceeds this limit,
that handle will be put in a pending state until another handle is
finished. The free connection will then be reused, if possible, or
closed if the pending handle can't reuse it.

Several new options for pipelining:

CURLMOPT_MAX_PIPELINE_LENGTH - Limits the pipeling length. If a
pipeline is "full" when a connection is to be reused, a new connection
will be opened if the CURLMOPT_MAX_xxx_CONNECTIONS limits allow it.
If not, the handle will be put in a pending state until a connection is
ready (either free or a pipe got shorter).

CURLMOPT_CONTENT_LENGTH_PENALTY_SIZE - A pipelined connection will not
be reused if it is currently processing a transfer with a content
length that is larger than this.

CURLMOPT_CHUNK_LENGTH_PENALTY_SIZE - A pipelined connection will not
be reused if it is currently processing a chunk larger than this.

CURLMOPT_PIPELINING_SITE_BL - A blacklist of hosts that don't allow
pipelining.

CURLMOPT_PIPELINING_SERVER_BL - A blacklist of server types that don't allow
pipelining.

See the curl_multi_setopt() man page for details.

@ -95,6 +95,112 @@ This option is for the multi handle's use only, when using the easy interface
you should instead use the \fICURLOPT_MAXCONNECTS\fP option.
(Added in 7.16.3)
.IP CURLMOPT_MAX_HOST_CONNECTIONS
Pass a long. The set number will be used as the maximum amount of
simultaneously open connections to a single host. For each new session to
a host, libcurl will open a new connection up to the limit set by
CURLMOPT_MAX_HOST_CONNECTIONS. When the limit is reached, the sessions will
be pending until there are available connections. If CURLMOPT_PIPELINING is
1, libcurl will try to pipeline if the host is capable of it.
The default value is 0, which means that there is no limit.
However, for backwards compatibility, setting it to 0 when CURLMOPT_PIPELINING
is 1 will not be treated as unlimited. Instead it will open only 1 connection
and try to pipeline on it.
(Added in 7.30.0)
.IP CURLMOPT_MAX_PIPELINE_LENGTH
Pass a long. The set number will be used as the maximum amount of requests
in a pipelined connection. When this limit is reached, libcurl will use another
connection to the same host (see CURLMOPT_MAX_HOST_CONNECTIONS), or queue the
requests until one of the pipelines to the host is ready to accept a request.
Thus, the total number of requests in-flight is CURLMOPT_MAX_HOST_CONNECTIONS *
CURLMOPT_MAX_PIPELINE_LENGTH.
The default value is 5.
(Added in 7.30.0)
.IP CURLMOPT_CONTENT_LENGTH_PENALTY_SIZE
Pass a long. If a pipelined connection is currently processing a request
with a Content-Length larger than CURLMOPT_CONTENT_LENGTH_PENALTY_SIZE, that
connection will not be considered for additional requests, even if it is
shorter than CURLMOPT_MAX_PIPELINE_LENGTH.
The default value is 0, which means that the penalization is inactive.
(Added in 7.30.0)
.IP CURLMOPT_CHUNK_LENGTH_PENALTY_SIZE
Pass a long. If a pipelined connection is currently processing a
chunked (Transfer-encoding: chunked) request with a current chunk length
larger than CURLMOPT_CHUNK_LENGTH_PENALTY_SIZE, that connection will not be
considered for additional requests, even if it is shorter than
CURLMOPT_MAX_PIPELINE_LENGTH.
The default value is 0, which means that the penalization is inactive.
(Added in 7.30.0)
.IP CURLMOPT_PIPELINING_SITE_BL
Pass an array of char *, ending with NULL. This is a list of sites that are
blacklisted from pipelining, i.e sites that are known to not support HTTP
pipelining. The array is copied by libcurl.
The default value is NULL, which means that there is no blacklist.
Pass a NULL pointer to clear the blacklist.
Example:
.nf
site_blacklist[] =
{
"www.haxx.se",
"www.example.com:1234",
NULL
};
curl_multi_setopt(m, CURLMOPT_PIPELINE_SITE_BL, site_blacklist);
.fi
(Added in 7.30.0)
.IP CURLMOPT_PIPELINING_SERVER_BL
Pass an array of char *, ending with NULL. This is a list of server types
prefixes (in the Server: HTTP header) that are blacklisted from pipelining,
i.e server types that are known to not support HTTP pipelining. The array is
copied by libcurl.
Note that the comparison matches if the Server: header begins with the string
in the blacklist, i.e "Server: Ninja 1.2.3" and "Server: Ninja 1.4.0" can
both be blacklisted by having "Ninja" in the backlist.
The default value is NULL, which means that there is no blacklist.
Pass a NULL pointer to clear the blacklist.
Example:
.nf
server_blacklist[] =
{
"Microsoft-IIS/6.0",
"nginx/0.8.54",
NULL
};
curl_multi_setopt(m, CURLMOPT_PIPELINE_SERVER_BL, server_blacklist);
.fi
(Added in 7.30.0)
.IP CURLMOPT_MAX_TOTAL_CONNECTIONS
Pass a long. The set number will be used as the maximum amount of
simultaneously open connections in total. For each new session, libcurl
will open a new connection up to the limit set by
CURLMOPT_MAX_TOTAL_CONNECTIONS. When the limit is reached, the sessions will
be pending until there are available connections. If CURLMOPT_PIPELINING is
1, libcurl will try to pipeline if the host is capable of it.
The default value is 0, which means that there is no limit.
However, for backwards compatibility, setting it to 0 when CURLMOPT_PIPELINING
is 1 will not be treated as unlimited. Instead it will open only 1 connection
and try to pipeline on it.

still resolve the second one properly to make sure that they actually _can_
be considered for pipelining. Also, asking for explicit pipelining on handle
X may be tricky when handle X get a closed connection.
- We need options to control max pipeline length, and probably how to behave
if we reach that limit. As was discussed on the list, it can probably be
made very complicated, so perhaps we can think of a way to pass all
variables involved to a callback and let the application decide how to act
in specific situations. Either way, these fancy options are only interesting
to work on when everything is working and we have working apps to test with.
