This is TOSBack version 2, a clean redesign & reimplementation of EFF's TOSBack project. It uses Git as an inherently and efficiently versioned backend storage database. After cloning the git repository, you need to execute this command: git submodule update --init --recursive That will fetch a recent version of the GitPython code, which we depend upon. *BUGS IN WGET* If you want to actually run the crawler yourself (not really necessary unless you're testing something), be aware that TOSBack2 also exposes a number of bugs in common versions of wget. As of December 2011, there are two bugs you might need to patch yourself! (FOR YOUR CONVENIENCE, a patched version of the wget source can be found in lib/wget-1.13.4/ . There is also a binary .deb that Debian and Ubuntu users can try in lib/. More hints on building from source below) 1. Versions of wget built against gnutls may suffer from fatal memory leaks https://lists.gnu.org/archive/html/bug-wget/2011-10/msg00050.html (so apply that patch, or build against openssl using ./configure --with-ssl=openssl). 2. You should also apply the following patch https://savannah.gnu.org/support/download.php?file_id=24473 to fix this bug: https://savannah.gnu.org/bugs/?21714 HINTS FOR BUILDING WGET FROM SOURCE ON DEBIAN OR UBUNTU sudo apt-get build-dep wget cd lib/wget-1.13.4/ fakeroot debian/rules binary an installable .deb file *should* be written to the lib/ directory
