This is unfortunate but help2man behaves badly when there is indented
lines in help messages in commnad-line args. We removed indentations
to make help2man happy.
This commit adds functionality to customize access logging format in
nghttpx. The format variables are inspired by nginx. The default
format is combined format.
This is not obvious but it makes intermediaries flush and forward DATA
frame boundary without excessive buffering. Since we have different
TCP connections frontend and backend, this may not work. This is
still experimental.
Use the same behaviour the current Google server does: start with 1300
TLS record size and after transmitting 1MiB, change record size to
16384. After 1 second idle time, reset to 1300. Only applies to
HTTP/2 and SPDY upstream connections.
Now the number of -v option specifies verbosity level. Current all
verbose output are turned on for at lest one -v option, except for the
debug output for each data chunk which is only turned on more than one
-v options.
* Add NGHTTP2_HTTP_1_1_REQUIRED error code
* Allow transmission of WINDOW_UPDATE on reserved (remote)
* Allow reception of WINDOW_UPDATE on reserved (local)
* Treat frame larger than MAX_FRAME_SIZE as FRAME_SIZE_ERROR
ALPN identifier is still h2-14 to continue interop, since draft-14 and
-15 are binary compatible. The new error code was added in draft-15,
but HTTP/2 allows extensions can freely add new error code, so it is
not a problem.
This is simply programming error, but it is interesting that using
libstdc++ does not reveal this error. With clang++-libc++, we got
std::system_error: mutex lock faild: Invalid argument. This is
because we did not give a name to lock object, so it is immediately
destructed. I think this will fix the reported crash on Mac OSX.
We may run into race condition if execve is called at the same time
when fcntl is called. But we just does this for now to compile
nghttp2 applications under older kernel.
The libnghttp2_asio library is C++ library built on top of libnghttp2.
Currently, it has server API and easily create HTTP/2 server using
node.js like API calls. See the example server source code in
examples/asio-sv.cc. The library depends on Boost::ASIO library.
Previously read and write timeouts work independently. When we are
writing response to the client, read timeout still ticks (e.g., HTTP/2
or tunneled HTTPS connection). So read timeout may occur during long
download. This commit fixes this issue. This commit only fixes the
upstream part. We need similar fix for the downstream.
With the combination of HTTP/1 upstream and HTTP/2 downstream,
downstream tells SHRPX_NO_BUFFER while connecting to the backend
server. Previously, we did not call upstream resume_read and upload
was blocked. This commit now calls upstream resume_read to unblock.
This commit also remove pending output buffer size of Http2Session
when calculating downstream connection's buffer is full. This is
desirable since we only operate resume_read by stream basis.
Android does not have _Exit. We detect this and use _exit instead.
clang-3.4 has an issue around undefined reference to
__atomic_fetch_add_4, so we stick to gcc-4.8 for now.
By default, nghttp2 library only handles HTTP/2 frames and does not
recognize first 24 bytes of client connection preface. This design
choice is done due to the fact that server may want to detect the
application protocol based on first few bytes on clear text
communication. But for simple servers which only speak HTTP/2, it is
easier for developers if nghttp2 library takes care of client
connection preface.
If this option is used with nonzero val, nghttp2 library checks first
24 bytes client connection preface. If it is not a valid one,
nghttp2_session_recv() and nghttp2_session_mem_recv() will return
error NGHTTP2_ERR_BAD_PREFACE, which is fatal error.
