This patch proposes to drop support for Python 2 in nbdkit. Rather than abruptly drop it everywhere, my proposal is that we point people to nbdkit 1.14 (the current stable version) if they want to continue with Python 2 plugins, while gently reminding them of the upcoming Python 2.7 end of life announcement. Libnbd never supported Python 2. Libguestfs in theory supports Python 2 but I dropped

v3 was here: https://www.redhat.com/archives/libguestfs/2019-November/msg00209.html In v4: - Rebase on top of current master. Includes various fixes and updates required because of Nir's patches that went into master. - Fix api_version() -> API_VERSION in patch 2 noted previously on the mailing list. Rich.

v2 was here: https://www.redhat.com/archives/libguestfs/2019-November/msg00163.html I pushed patch 1 (with spelling fix), patch 4 and patch 5 since those were previously ACKed on the list. Differences in v3: - Add error checking to PyModule_AddIntConstant. - Use API_VERSION constant instead of function. - Add max API version supported to --dump-plugin output. - Print API_VERSION selected by

And fill out most of the missing bits of the API. Rich.
