Tatsuhiro Tsujikawa 28fe3e7e89 More warning flags for --enable-werror 2015-09-23 16:49:45 +09:00
Tatsuhiro Tsujikawa f3288092e8 Strictly check occurrence of dynamic table size update
RFC 7541 requires that dynamic table size update must occur at the
beginning of the first header block, and is signaled as SETTINGS
acknowledgement.  This commit checks these conditions.  If dynamic
table size update appears other than the beginning of the first header
block, it is treated as error.  If SETTINGS ACK is received, and next
HEADERS header block does not have dynamic table size update, it is
treated as error.

Tatsuhiro Tsujikawa 82e2c5bd22 Never index authorization and small cookie header field
nghttp2 library now use Literal Header Field never Indexed for
"authorization" header field and small "cookie" header field,
regardless of nghttp2_nv.flags.

Tatsuhiro Tsujikawa 661fb2eb0e NULL-terminate name and value in nghttp2_nv
Guaranteeing NULL-termination is very useful when name or value are
used with C functions which requires NULL-terminated string.

Tatsuhiro Tsujikawa c0ffed7788 Support custom memory allocator
nghttp2_mem structure is introduced to hold custom memory allocator
functions and user supplied pointer.  nghttp2_mem object can be passed
to nghttp2_session_client_new3(), nghttp2_session_server_new3(),
nghttp2_hd_deflate_new2() and nghttp2_hd_inflate_new2() to replace
standard malloc(), free(), calloc() and realloc().  nghttp2_mem
structure has user supplied pointer mem_user_data which can be used as
per session/object memory pool.

Tatsuhiro Tsujikawa 31de732e3b Allocate header table ringbuffer lazily
Previously in inflater we reserve new ringbuffer when table size is
changed.  This may be potentially a problem if new table size is very
large number.  When inflater is not used directly by application, this
is not a problem because application can choose the buffer size.  On
the other hand, if application uses inflater directly and it does not
have control of new buffer size (e.g., protocol dissector), then we
just fail to allocate large buffer in
nghttp2_hd_inflate_change_table_size() without actually use such huge
buffer.  This change defers the actual allocation of buffer when it is
actually needed so that we will fail when it is absolutely needed.

Tatsuhiro Tsujikawa 8317559090 nghttp2_hd: Implement stream header inflater
This stream inflater can inflate incoming header block in streaming
fashion. Currently, we buffer up single name/value pair, but we chose
far more smaller buffer size than HTTP/2 frame size.

Tatsuhiro Tsujikawa 0e4b3d435e Emit header name/value pair using callback functions
Now, in nghttp2_on_frame_recv_callback, nva and nvlen in
HEADERS and PUSH_PROMISE frames are always NULL and 0 respectively.
The header name/value pairs are emitted successive
nghttp2_on_header_callback functions. The end of header fields are
signaled with nghttp2_on_end_headers_callback function.

Since NGHTTP2_ERR_PAUSE for nghttp2_on_frame_recv_callback is
introduced to handle header block, it is now deprecated.
Instead, nghttp2_on_header_callback can be paused using
NGHTTP2_ERR_PAUSE.

Tatsuhiro Tsujikawa 94ec4dbe42 nghttpd_hd: Update static table and use 1-based index
The specification now says that index to the header table entry is
1-based. Since 0-based index is very handy to access arrays, we
internally uses 0-based index. We just convert it to 1-based when
we emit to the block and convert 1-based to 0-based on decoding.

Tatsuhiro Tsujikawa 40347487c9 Don't sort headers in library code
Remove sorting headers from library code. The application must sort
them if necessary. nghttpx and nghttpd do the sorting of the headers
in stable way if names are equal.

Tatsuhiro Tsujikawa 94263216fb Add nghttp2_submit_request2
This function is similar to nghttp2_submit_request and the
difference is it takes an array of nghttp2_nv as name/value pairs.
It is useful if name/value pairs is not NULL-terminated in the
application code.
