Adopt nghttp3_conn_read_stream2 which requires nghttp3 v1.12.0. To
pass the current timestamp, ngtcp2_conn_get_timestamp is used, which
requires ngtcp2 v1.16.0.
This commit removes OCSP stapling features and the following options
are deprecated and have no effect:
- fetch-ocsp-response-file
- no-ocsp
- no-verify-ocsp
- ocsp-update-interval
This commit deprecates all APIs, including structs and callback
functions, that use ssize_t. New APIs that use nghttp2_ssize are
added as a replacement. The usage of ssize_t is problematic for
several reasons. Some platforms do not define ssize_t. The minimum
value of ssize_t that POSIX requires is -1 which makes nghttp2 error
code out of range. nghttp2_ssize is an alias of ptrdiff_t that is in
C standard and covers our error code range.
New code should use new nghttp2_ssize APIs. The existing applications
should consider migrating to new APIs.
The deprecated ssize_t APIs continue to work for backward
compatibility.
Here is the summary of the deprecated APIs and their replacements:
Callback functions:
- nghttp2_data_source_read_callback => nghttp2_data_source_read_callback2
- nghttp2_data_source_read_length_callback => nghttp2_data_source_read_length_callback2
- nghttp2_pack_extension_callback => nghttp2_pack_extension_callback2
- nghttp2_recv_callback => nghttp2_recv_callback2
- nghttp2_select_padding_callback => nghttp2_select_padding_callback2
- nghttp2_send_callback => nghttp2_send_callback2
Structs:
- nghttp2_data_provider => nghttp2_data_provider2
Functions:
- nghttp2_hd_deflate_hd => nghttp2_hd_deflate_hd2
- nghttp2_hd_deflate_hd_vec => nghttp2_hd_deflate_hd_vec2
- nghttp2_hd_inflate_hd2 => nghttp2_hd_inflate_hd3
- nghttp2_pack_settings_payload => nghttp2_pack_settings_payload2
- nghttp2_session_callbacks_set_data_source_read_length_callback =>
nghttp2_session_callbacks_set_data_source_read_length_callback2
- nghttp2_session_callbacks_set_pack_extension_callback =>
nghttp2_session_callbacks_set_pack_extension_callback2
- nghttp2_session_callbacks_set_recv_callback =>
nghttp2_session_callbacks_set_recv_callback2
- nghttp2_session_callbacks_set_select_padding_callback =>
nghttp2_session_callbacks_set_select_padding_callback2
- nghttp2_session_callbacks_set_send_callback =>
nghttp2_session_callbacks_set_send_callback2
- nghttp2_session_mem_recv => nghttp2_session_mem_recv2
- nghttp2_session_mem_send => nghttp2_session_mem_send2
- nghttp2_submit_data => nghttp2_submit_data2
- nghttp2_submit_request => nghttp2_submit_request2
- nghttp2_submit_response => nghttp2_submit_response2
For those applications that do not want to see ssize_t in nghttp2.h
header file, define NGHTTP2_NO_SSIZE_T macro before including
nghttp2.h. It hides all ssize_t APIs.
