Add nghttp2_option_set_server_fallback_rfc7540_priorities. If it is
set to nonzero, and server submits SETTINGS_NO_RFC7540_PRIORITIES = 1,
but it does not receive SETTINGS_NO_RFC7540_PRIORITIES from client,
server falls back to RFC 7540 priorities. Only minimal set of
features are enabled in this fallback case.
This commit adds PRIORITY_UPDATE frame support. Applying incoming
PRIORITY_UPDATE frame to server push stream is not implemented.
Client can send PRIORITY_UPDATE frame by calling
nghttp2_submit_priority_update.
Server opts to receive PRIORITY_UPDATE frame by the call
nghttp2_option_set_builtin_recv_extension_type(option,
NGHTTP2_PRIORITY_UPDATE), and passing the option to
nghttp2_session_server_new2 or nghttp2_session_server_new3.
This commit implements RFC 9218 extensible prioritization scheme. It
is enabled when a local endpoint submits
SETTINGS_NO_RFC7540_PRIORITIES = 1. This commit only handles priority
signal in HTTP request header field. Priority header field in
PUSH_PROMISE is not supported.
HTTP messaging must be enabled to take advantage of this
prioritization scheme because HTTP fields are not parsed if HTTP
messaging is disabled.
Fix the bug that causes a stream to stall when a receiver, which
enables nghttp2_option_set_no_auto_window_update() option on, sends
SETTINGS_INITIAL_WINDOW_SIZE with the value that is less than or equal
to the amount of data received. Previously, in this particular case,
when SETTINGS is acknowledged by the sender, the receiver does not try
to send WINDOW_UPDATE frame. The sender is unable to send more data
because its stream-level window size is smaller than or equal to the
amount of data it has sent.
When applying new header table size acknowledged with SETTINGS ACK by
an encoder, change the header table size on a decoder only when it
strictly lowers the current maximum table size set by Dynamic Table
Size Update from the encoder or the default size 4096 if no Dynamic
Table Size Update is received.
Previously, the header table size on a decoder is always changed. If
a maximum size in SETTINGS are increased (e.g., 4096 -> 8192), and
then decreased to the previous value, the decoder incorrectly requires
Dynamic Table Size Update from an encoder.
Check the allowed characters for ":method" (see RFC 7230, section 3.2.6) and
":path". For ":path", the space and tab characters are now forbidden, but
other special characters are still allowed for compatibility reasons.
Update genvchartbl.py so that it generates the same table as in the code.
Fixes#1611
The previous wording implied that if send_callback doesn't return
NGHTTP2_ERR_WOULDBLOCK, this function would always send all
submitted requests / data. This is not the case, since flow control can
cause some data to remain queued until WINDOW_UPDATE is received.
Previously, if automatic window update is enabled (which is default),
after window size is set to 0 by
nghttp2_session_set_local_window_size, once the receiving window is
exhausted, even after window size is increased by
nghttp2_session_set_local_window_size, no more data cannot be
received. This is because nghttp2_session_set_local_window_size does
not submit WINDOW_UPDATE. It is only triggered when new data arrives
but since window is filled up, no more data cannot be received, thus
dead lock happens.
This commit fixes this issue. nghttp2_session_set_local_window_size
submits WINDOW_UPDATE if necessary.

It can be set via the `STATIC_LIB_SUFFIX` variable.
This fixes every existing dependent project that relied on the name
having no suffix and thus capable of using either a static or shared
flavour depending on which one is present on this or how the linker
is configured.

This commit fixes the bug that stream is closed with wrong error code
(0). This happens when STREAM or DATA frame with END_STREAM flag set
is received and it violates HTTP messaging rule (i.e., content-length
does not match) and the other side of stream has been closed. In this
case, nghttp2_on_stream_close_callback should be called with nonzero
error code, but previously it is called with 0 (NO_ERROR).
