Hello, I made changes to support OpenSSL and other TLS engines. You will find my working branch here: https://github.com/ghaderer/libmicrohttpd/tree/wip-openssl-master. Could you review it and tell me if this is something you could integrate? If you don't, what should be done to improve it and have it checked in? I tested on Linux/amd64. All existing tests pass. Not tested on Windows at all. Cheers, Gauthier |

Hello. Thanks a lot for implementing and sharing it, I'm going to test your changes as soon as possible. OpenSSL support is an awesome feature, it requires a detailed test ... |

Hello again @ghaderer . I took a look at your changes, really impressive. However, I've tried to compile it on my Xubuntu and got the following error: ./configure --with-gnutls=no --with-openssl=yes make [snip] gcc -DHAVE_CONFIG_H -I. -I../.. -I../../src/include -DDATA_DIR=\"../../src/datadir/\" -DCPU_COUNT=8 -g -O2 -fno-strict-aliasing -MT benchmark-benchmark.o -MD -MP -MF .deps/benchmark-benchmark.Tpo -c -o benchmark-benchmark.o `test -f 'benchmark.c' || echo './'`benchmark.c mv -f .deps/benchmark-benchmark.Tpo .deps/benchmark-benchmark.Po /bin/bash ../../libtool --tag=CC --mode=link gcc -g -O2 -fno-strict-aliasing -o benchmark benchmark-benchmark.o ../../src/microhttpd/libmicrohttpd.la libtool: link: gcc -g -O2 -fno-strict-aliasing -o .libs/benchmark benchmark-benchmark.o ../../src/microhttpd/.libs/libmicrohttpd.so -pthread ../../src/microhttpd/.libs/libmicrohttpd.so: undefined reference to `MHD_TLS_del_session' ../../src/microhttpd/.libs/libmicrohttpd.so: undefined reference to `MHD_TLS_del_context' ../../src/microhttpd/.libs/libmicrohttpd.so: undefined reference to `MHD_TLS_create_context' ../../src/microhttpd/.libs/libmicrohttpd.so: undefined reference to `MHD_TLS_set_context_client_certificate_mode' ../../src/microhttpd/.libs/libmicrohttpd.so: undefined reference to `MHD_TLS_set_context_certificate_cb' ../../src/microhttpd/.libs/libmicrohttpd.so: undefined reference to `MHD_TLS_session_wants_write' ../../src/microhttpd/.libs/libmicrohttpd.so: undefined reference to `MHD_set_https_callbacks' ../../src/microhttpd/.libs/libmicrohttpd.so: undefined reference to `MHD_TLS_global_deinit' ../../src/microhttpd/.libs/libmicrohttpd.so: undefined reference to `MHD_tls_connection_shutdown' ../../src/microhttpd/.libs/libmicrohttpd.so: undefined reference to `MHD_TLS_session_read' ../../src/microhttpd/.libs/libmicrohttpd.so: undefined reference to `MHD_TLS_get_session_protocol_version' ../../src/microhttpd/.libs/libmicrohttpd.so: undefined reference to `MHD_TLS_get_specific_session' ../../src/microhttpd/.libs/libmicrohttpd.so: undefined reference to `MHD_TLS_session_close' ../../src/microhttpd/.libs/libmicrohttpd.so: undefined reference to `MHD_TLS_session_read_pending' ../../src/microhttpd/.libs/libmicrohttpd.so: undefined reference to `MHD_run_tls_handshake_' ../../src/microhttpd/.libs/libmicrohttpd.so: undefined reference to `MHD_TLS_set_context_trust_certificate' ../../src/microhttpd/.libs/libmicrohttpd.so: undefined reference to `MHD_TLS_get_session_cipher_algorithm' ../../src/microhttpd/.libs/libmicrohttpd.so: undefined reference to `MHD_TLS_session_wants_read' ../../src/microhttpd/.libs/libmicrohttpd.so: undefined reference to `MHD_TLS_set_context_cipher_priorities' ../../src/microhttpd/.libs/libmicrohttpd.so: undefined reference to `MHD_TLS_lookup_engine' ../../src/microhttpd/.libs/libmicrohttpd.so: undefined reference to `MHD_TLS_create_session' ../../src/microhttpd/.libs/libmicrohttpd.so: undefined reference to `MHD_TLS_engine_has_feature' ../../src/microhttpd/.libs/libmicrohttpd.so: undefined reference to `MHD_TLS_set_context_dh_params' ../../src/microhttpd/.libs/libmicrohttpd.so: undefined reference to `MHD_TLS_global_init' ../../src/microhttpd/.libs/libmicrohttpd.so: undefined reference to `MHD_TLS_set_context_certificate' ../../src/microhttpd/.libs/libmicrohttpd.so: undefined reference to `MHD_TLS_session_write' collect2: error: ld returned 1 exit status Makefile:734: recipe for target 'benchmark' failed make[4]: *** [benchmark] Error 1 make[4]: Leaving directory '/home/silvioprog/dev/git/libmicrohttpd2/src/examples' Makefile:938: recipe for target 'all-recursive' failed make[3]: *** [all-recursive] Error 1 make[3]: Leaving directory '/home/silvioprog/dev/git/libmicrohttpd2/src/examples' Makefile:418: recipe for target 'all-recursive' failed make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory '/home/silvioprog/dev/git/libmicrohttpd2/src' Makefile:549: recipe for target 'all-recursive' failed make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory '/home/silvioprog/dev/git/libmicrohttpd2' Makefile:454: recipe for target 'all' failed make: *** [all] Error 2 It should link openssl by itself.

Hello silvioprog, Thank you for taking time to test and review my changes. Regarding the missing symbols issue, I broke the HTTPS support auto-detection. For the second issue, it was due to a typo which caused the build to break when GnuTLS was enabled but not OpenSSL. I fixed both of them and pushed on the same branch. I hope I did not make other mistakes! :-/ Let me know if you have other issues or questions regarding all of this. |
