gdb/python: remove Python 2 support New in this version: - Add a PY_MAJOR_VERSION check in configure.ac / AC_TRY_LIBPYTHON. If the user passes --with-python=python2, this will cause a configure failure saying that GDB only supports Python 3. Support for Python 2 is a maintenance burden for any patches touching Python support. Among others, the differences between Python 2 and 3 string and integer types are subtle. It requires a lot of effort and thinking to get something that behaves correctly on both. And that's if the author and reviewer of the patch even remember to test with Python 2. See this thread for an example: https://sourceware.org/pipermail/gdb-patches/2021-December/184260.html So, remove Python 2 support. Update the documentation to state that GDB can be built against Python 3 (as opposed to Python 2 or 3). Update all the spots that use: - sys.version_info - IS_PY3K - PY_MAJOR_VERSION - gdb_py_is_py3k ... to only keep the Python 3 portions and drop the use of some now-removed compatibility macros. I did not update the configure script more than just removing the explicit references to Python 2. We could maybe do more there, like check the Python version and reject it if that version is not supported. Otherwise (with this patch), things will only fail at compile time, so it won't really be clear to the user that they are trying to use an unsupported Python version. But I'm a bit lost in the configure code that checks for Python, so I kept that for later. Change-Id: I75b0f79c148afbe3c07ac664cfa9cade052c0c62
