IronPython.Zlib implements the zlib module for IronPython using ComponentAce’s zlib.net, which is a purely managed implementation of the zlib library. IronPython.Zlib is entirely managed code and works with both 32-bit and 64-bit IronPython. It passes all of the Python 2.6 zlib and gzip tests and most of the zipfile tests.
IronPython.SQLite is a port of pysqlite to IronPython using C#-SQLite, which, similar to zlib.net, is a managed implementation of SQLite. Thus, IronPython.SQLite is also 100% managed code. It passes about 87% of the Python 2.6 sqlite3 tests; the remaining ones are mostly corner cases or rarely used functionality.
