Build Status

Auditing for TLS certificates.

Dependencies

  • A working C++11 compiler.

  • OpenSSL, at least 1.0.0q, preferably 1.0.1l or 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.

Gmock provides a bundled version of gtest, which will also be used.

Unpack googlemock, 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 gmock/gtest automatically.

Some systems make the googlemock source available as a package; on Debian, this is in the google-mock package, which puts it in /usr/src/gmock. Our Makefile looks in that location by default, but if your googlemock sources are in a different location, set the GMOCKDIR environment variable to point at them.

If you are on FreeBSD, you may need to apply the patch in gtest.patch to the gtest subdirectory of gmock.

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.

You can specify a non-installed locally built library using the LIBEVENTDIR environment variable to point to the local build. Note that the FreeBSD port version 2.0.21_2 does not appear to work correctly (it only listens on IPv6 for the HTTP server) - for that platform we had to build from the source, specifically commit 6dba1694c89119c44cef03528945e5a5978ab43a.

  • ldns
  • ant
  • Python libraries:
  • pyasn1 and pyasn1-modules (optional, needed for upload_server_cert.sh)
  • dnspython

Building

You can build the log server with the following commands:

$ ./autogen.sh  # only necessary if you're building from git
$ ./configure
$ make

You can give the configure script extra parameters, to set compilation flags, or point to custom versions of some dependencies (notably, googlemock often needs this). For example, to compile with Clang, using googlemock in $HOME/gmock, and a custom libevent in $HOME/libevent:

$ ./configure CXX=clang++ GMOCK_DIR=$HOME CPPFLAGS="-I$HOME/libevent/include" LDFLAGS="-L$HOME/libevent/.libs"

Running ./configure --help provides more information about various variables that can be set.

Running Unit Tests

Run unit tests with this command

$ make check

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.

End-To-End Tests

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.

Testing and Logging Options

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.
