Almost all of the Python code in the respository has been updated to be compatibile with Python 2.6, Python 3.4, or newer. The only exceptions are arc_summery3.py which requires Python 3, and pyzfs which requires at least Python 2.7. This allows us to maintain a single version of the code and support most default versions of python. This change does the following: * Sets the default shebang for all Python scripts to python3. If only Python 2 is available, then at install time scripts which are compatible with Python 2 will have their shebangs replaced with /usr/bin/python. This is done for compatibility until Python 2 goes end of life. Since only the installed versions are changed this means Python 3 must be installed on the system for test-runner when testing in-tree. * Added --with-python=<2|3|3.4,etc> configure option which sets the PYTHON environment variable to target a specific python version. By default the newest installed version of Python will be used or the preferred distribution version when creating pacakges. * Fixed --enable-pyzfs configure checks so they are run when --enable-pyzfs=check and --enable-pyzfs=yes. * Enabled pyzfs for Python 3.4 and newer, which is now supported. * Renamed pyzfs package to python<VERSION>-pyzfs and updated to install in the appropriate site location. For example, when building with --with-python=3.4 a python34-pyzfs will be created which installs in /usr/lib/python3.4/site-packages/. * Renamed the following python scripts according to the Fedora guidance for packaging utilities in /bin - dbufstat.py -> dbufstat - arcstat.py -> arcstat - arc_summary.py -> arc_summary - arc_summary3.py -> arc_summary3 * Updated python-cffi package name. On CentOS 6, CentOS 7, and Amazon Linux it's called python-cffi, not python2-cffi. For Python3 it's called python3-cffi or python3x-cffi. * Install one version of arc_summary. Depending on the version of Python available install either arc_summary2 or arc_summary3 as arc_summary. The user output is only slightly different.

README
This package provides a wrapper for libzfs_core C library. libzfs_core is intended to be a stable interface for programmatic administration of ZFS. This wrapper provides one-to-one wrappers for libzfs_core API functions, but the signatures and types are more natural to Python. nvlists are wrapped as dictionaries or lists depending on their usage. Some parameters have default values depending on typical use for increased convenience. Enumerations and bit flags become strings and lists of strings in Python. Errors are reported as exceptions rather than integer errno-style error codes. The wrapper takes care to provide one-to-many mapping of the error codes to the exceptions by interpreting a context in which the error code is produced. Unit tests and automated test for the libzfs_core API are provided with this package. Please note that the API tests perform lots of ZFS dataset level operations and ZFS tries hard to ensure that any modifications do reach stable storage. That means that the operations are done synchronously and that, for example, disk caches are flushed. Thus, the tests can be very slow on real hardware. It is recommended to place the default temporary directory or a temporary directory specified by, for instance, TMP environment variable on a memory backed filesystem.
