Auditing for TLS certificates.
- OpenSSL, at least 1.0.0, preferably 1.0.2 (and up)
The checking of SCTs included in the RFC 6962 TLS extension is only included in OpenSSL 1.0.2. As of this writing, this version is not yet released, so this means hand building the OpenSSL_1_0_2-stable
branch from the OpenSSL git repository.
- CMake
- googletest (tested with 1.6.0)
Unpack googletest, but do not build it. Upstream recommends to build a new copy from source for each package to be tested. We follow this advice in our Makefile
, which builds gtest automatically.
Some systems make the googletest source available as a package; on Debian, this is in the libgtest-dev package, which puts it in /usr/src/gtest
. Our Makefile
looks in that location by default, but if your googletest sources are in a different location, set the GTESTDIR
environment variable to point at them.
Make sure to install glog after gflags, to avoid linking errors.
You can specify a JSON-C library in a non-standard location using the JSONCLIBDIR
environment variable. Version 0.10 would work as well, except the json_object_iterator.h
header is not properly copied when installing. If you can install the missing header manually, it should work.
- libevent (tested with 2.0.21-stable)
You can specify a non-installed locally built library using the
LIBEVENTDIR
environment variable to point to the local build.
- ldns
- ant
- Python libraries:
- pyasn1 and pyasn1-modules (optional, needed for
upload_server_cert.sh
) - dnspython
You can build the log server by pointing to your custom OpenSSL and/or gtest (if needed):
$ make OPENSSLDIR=<path to openssl> GTESTDIR=<path to gtest> LIBEVENTDIR=<path to libevent>
If you need to set custom options for your compiler, then you can do this by setting LOCAL_CXXFLAGS. You can also customise the C++ compile in cpp/local.mk.
Once more, use gmake on BSD systems.
Run unit tests with this command
$ make OPENSSLDIR=<path to openssl> GTESTDIR=<path to gtest> test
If the build still fails because of missing libraries, you may need to set the
environment variable LD_LIBRARY_PATH
. On Linux, if you did not change the
default installation path (such as /usr/local/lib
), running
$ ldconfig
or, if needed,
$ sudo ldconfig
should resolve the problem.
For end-to-end server-client tests, you will need to install Apache
and point the tests to it. See test/README
for how to do so.
Note that several tests write files on disk. The default directory for
storing temporary testdata is /tmp
. You can change
this by setting TMPDIR=<tmpdir>
for make.
End-to-end tests also create temporary certificate and server files in
test/tmp
. All these files are cleaned up after a successful test run.
For logging options, see http://google-glog.googlecode.com/svn/trunk/doc/glog.html
By default, unit tests log to stderr, and log only messages with a FATAL level (i.e., those that result in abnormal program termination). You can override the defaults with command-line flags.
End-to-end tests log everything at INFO level and above.
