Daniel Stenberg d6f1c74330 pipeline: switch some code over to functions 
... to "compartmentalize" a bit and make it easier to change behavior
when multiplexing is used instead of good old pipelining.

Daniel Stenberg 7d0df07e48 symbols-in-versions: add CURLOPT_PIPEWAIT 2015-05-18 09:33:47 +02:00
Daniel Stenberg 811443754a CURLOPT_PIPEWAIT: added 
By setting this option to 1 libcurl will wait for a connection to reveal
if it is possible to pipeline/multiplex on before it continues.

Daniel Stenberg 38bd6bf0bb bundles: store no/default/pipeline/multiplex 
to allow code to act differently on the situation.

Also added some more info message for the connection re-use function to
make it clearer when connections are not re-used.

Daniel Stenberg be4c8fd1ef http2: lazy init header_recvbuf 
It makes us use less memory when not doing HTTP/2 and subsequently also
makes us not have to cleanup HTTP/2 related data when not using HTTP/2!

Tatsuhiro Tsujikawa 2ce2f03007 http2: Fix bug that data to be drained are overwritten by pending "paused" data 2015-05-18 08:57:18 +02:00
Tatsuhiro Tsujikawa d722138f29 http2: Don't call nghttp2_session_mem_recv while it is paused by a stream 2015-05-18 08:57:18 +02:00
Tatsuhiro Tsujikawa 0dc0de0351 http2: Read data left in connection buffer after pause 
Previously when we do pause because of out of buffer, we just throw
away unread data in connection buffer.  This just broke protocol
framing, and I saw occasional FRAME_SIZE_ERROR.  This commit fix this
issue by remembering how much data read, and in the next iteration, we
process remaining data.

Tatsuhiro Tsujikawa d261652d42 http2: Fix streams get stuck 
This commit fixes the bug that streams get stuck if stream gets some
DATA, and stream->closed becomes true at the same time.  Previously,
in this condition, after we processed DATA, we are going to try to
read data from underlying transport, but there is no data, and gets
EAGAIN.  There was no code path to evaludate stream->closed.

Daniel Stenberg 591a6933da pipeline: move function to pipeline.c and make static 
... as it was only used from there.

Daniel Stenberg e91aedd840 IsPipeliningPossible: http2 can always "pipeline" (multiplex) 2015-05-18 08:57:18 +02:00
Daniel Stenberg ee3ad233a2 http2: remove debug logging from on_frame_recv 2015-05-18 08:57:18 +02:00
Daniel Stenberg 70b5b698b0 http2: remove the closed check in http2_recv 
With the "drained" functionality we can get here slightly asynchronously
so the stream have have been closed but there is pending data left to
read.

Daniel Stenberg a28734be09 http2: bump the h2 buffer to 8K 2015-05-18 08:57:18 +02:00
Daniel Stenberg 5252f13dfa http2: Curl_read should not use the single buffer 
... as it does for pipelining when we're multiplexing, as we need the
different buffers to store incoming data correctly for all streams.

No need to wait for our "spot" like for pipelining

Daniel Stenberg 01e1bdb10c http2: force "drainage" of streams 
... which is necessary since the socket won't be readable but there is
data waiting in the buffer.

Daniel Stenberg 7bbac214f5 http2: move the mem+len pair to the stream struct 2015-05-18 08:57:17 +02:00
Daniel Stenberg 84c6b6561f http2: more stream-oriented data, stream ID 0 is for connections 2015-05-18 08:57:17 +02:00
Daniel Stenberg 2c238ea1fc http2: move lots of state data to the 'stream' struct 
... from the connection struct. The stream one being the 'struct HTTP'
which is kept in the SessionHandle struct (easy handle).

lookup streams for incoming frames in the stream hash, hashing is based
on the stream id and we get the SessionHandle for the incoming stream
that way.

Daniel Stenberg f858624052 Curl_http2_setup: only do it once and enable multiplex on the server 
Once we know we are HTTP/2 enabled we know the server can multiplex.
 2015-05-18 08:54:54 +02:00
Daniel Stenberg 6e6b02f398 http: switch on "pipelining" (multiplexing) for HTTP/2 servers 
... and do not blacklist any.

Daniel Stenberg 5fa82ca56f README.pipelining: removed 
All the details mentioned here are better documented in man pages
 2015-05-15 22:34:12 +02:00
Dan Fandrich 1c01cee601 build: removed bundles.c from make files 
This file was removed in commit fd137786

Daniel Stenberg 750d678c0e Curl_conncache_add_conn: fix memory leak on OOM 2015-05-14 14:06:44 +02:00
Daniel Stenberg a6af3df660 CURLMOPT_MAX_HOST_CONNECTIONS: host = host name + port number 2015-05-12 23:47:01 +02:00
Daniel Stenberg 2a746f6c28 conncache: keep bundles on host+port bases, not only host names 
Previously we counted all connections to a specific host name and that
would be used for the CURLMOPT_MAX_HOST_CONNECTIONS check for example,
while servers on different port numbers are normally considered
different "origins" on the web and should thus be considered different
hosts.
 2015-05-12 23:40:10 +02:00
Daniel Stenberg fd137786e5 bundles: merged into conncache.c 
All the existing Curl_bundle* functions were only ever used from within
the conncache.c file, so I moved them over and made them static (and
removed the Curl_ prefix).
 2015-05-12 23:21:33 +02:00
Daniel Stenberg b419e7ae0c hostcache: made all host caches use structs, not pointers 
This avoids unnecessary dynamic allocs and as this also removed the last
users of *hash_alloc() and *hash_destroy(), those two functions are now
removed.

Daniel Stenberg d37e0160c2 multi: converted socket hash into non-allocated struct 
avoids extra dynamic allocation
 2015-05-12 09:28:37 +02:00
Daniel Stenberg 640296c95d connection cache: avoid Curl_hash_alloc() 
... by using plain structs instead of pointers for the connection cache,
we can avoid several dynamic allocations that weren't necessary.
