As expected, OMVF building failed the test. It's actually a task noted in the wiki page: https://github.com/tianocore/tianocore.github.io/wiki/Tasks-BaseTools-Python3-Support Maybe it's time to convert the python scripts gradully. This patchset doesn't make the python scripts in BaseTools compatible with python3 immediately. It aims to do the trivial and safe conversion and replacement to make some statements compatible with both python2 and python3, so we can deal with the difficult cases later. With the help of "futurize" from python-future, it's easier to refactor the statements. This patchset is basically equivalent to "futurize -1" plus "StringIO.StringIO => io.BytesIO" and minus "fix_absolute_import". The reason to skip "fix_absolute_import" is that python2 failed to find some modules after converting to absolute import, and it might take time to figure out a proper fix. For the "io.BytesIO" change, it MIGHT introduce slow down to the build time since io.BytesIO is slower than StringIO.StringIO in python2(*). For a quick test, I built OVMF with the following command based on 8ab0bd2397c9d3922e0c7dbb1aa6f7e08799079f: $ rm -rf Build && make -C BaseTools/ clean $ time ./OvmfPkg/build.sh -D SECURE_BOOT_ENABLE \ -D NETWORK_IP6_ENABLE \ -D HTTP_BOOT_ENABLE \ -D TLS_ENABLE Before io.BytesIO: Build total time: 00:03:56 real 4m22.991s user 3m55.874s sys 0m27.250s After io.BytesIO: Build total time: 00:03:57 real 4m23.953s user 3m57.526s sys 0m27.192s The difference is only 1 second, and I would say the impact is subtle. The next step will be fixing relative import and maybe applying more futurize fixes. We won't get there soon but at least we are moving...
