A Debian user pointed out (http://bugs.debian.org/293932), that the current license for the Python profiler is not conforming to the DFSG (Debian free software guidelines). http://www.python.org/doc/current/lib/node829.html states "This permission is explicitly restricted to the copying and modification of the software to remain in Python, compiled Python, or other languages (such as C) wherein the modified or derived code is exclusively imported into a Python module." The DFSG, http://www.debian.org/doc/debian-policy/ch-archive.html#s-dfsg, third paragraph state: "Derived Works The license must allow modifications and derived works, and must allow them to be distributed under the same terms as the license of the original software." - Does somebody knows about the history of this license, why it is more restricted than the Python license? - Is there a chance to change the license for these two modules (profile.py, pstats.py)? The md5.h/md5c.c files allow "copy and use", but no modification of the files. There are some alternative implementations, i.e. in glibc, openssl, so a replacement should be sage. Any other requirements when considering a replacement? Matthias
