This adds h2 http support for the client api.
The public client api requires no changes, it will detect by
ALPN if the server can handle http/2, if so, it will use it.
Multiple client connections using the lws api will be mapped on
to the same single http/2 + tls socket using http/2 streams
that are serviced simultaneously where possible.
1) Introduce LWS_WITH_GCOV to build with gcc / clang coverage instrumentation.
$ cd build
$ make clean && rm -f `find . -name "*.gcno" -o -name "*.gcda"` && make -j16 && sudo make install && sudo /usr/local/bin/libwebsockets-test-server -s
...
$ gcov `find . -name *.c.gcno | grep -v test-apps` -b | sed "/\.h.\$/,/^$/d"
The above are available in two helper scripts
- scripts/build-gcov.sh
- scripts/gcov.sh
2)
CMake defaults changed:
- LWS_WITH_ZIP_FOPS: OFF
- LWS_WITH_RANGES: OFF
- LWS_WITHOUT_EXTENSIONS: ON
- LWS_WITH_ZLIB: OFF
New CMake controls that default-OFF:
- LWS_WITH_GENHASH
- LWS_WITH_GENRSA
these are implied by LWS_WITH_JWS (which is implied by LWS_WITH_ACME)
3) rename ./lib/tls/XXX/server.c and client.c to XXX-server.c / XXX-client.c.
This is because gcov dumps its results using the .c filename part only,
the copies overwrite each other if there are different .c files in the tree
with the same filename part.
4) Add onetime test-client mode and test to ./test-apps/attack.sh
5) Add gcov howto in READMEs/README.build.md using attack.sh
This adds a single api on lws that allows querying elements from the
peer certificate on a connection.
The api works the same regardless of the TLS backend.
- introduce lib/tls/mbedtls lib/tls/openssl
- move wrapper into lib/tls/mbedtls/wrapper
- introduce private helpers to hide backend
This patch doesn't replace or remove the wrapper, it moves it
to lib/tls/mbedtls/wrapper.
But it should be now that the ONLY functions directly consuming
wrapper apis are isolated in
- lib/tls/mbedtls/client.c (180 lines)
- lib/tls/mbedtls/server.c (317 lines)
- lib/tls/mbedtls/ssl.c (325 lines)
In particular there are no uses of openssl or mbedtls-related
constants outside of ./lib/tls any more.
