Spiny

----------------

- Fixed a bug on Python pre-release versions.

----------------

- Using /dev/null as stdin means the tests doesn't hang, but errors out.

- No redirection of test output (or input) when only using one process.

- It's not a library, so supporting Python 2 isn't needed.

----------------

- CTRL-C will now kill the program.

- Renamed {envpath} to {envdir}, {python} to {envpython} and {project_dir} to
{projectdir}. Also added {basepython} to the Python version used to install
the virtual env.

- Various changes to make custom commands more stable and flexible.

- Added a changedir option to the config.

- You can now run tests for Pythons that does not support any version
of virtualenv, such as Python 2.3 and earlier.

- Gives a nice error message and exits with -1 if it doesn't know what
versions to use.

- Dropped support for running Spiny with Python 2.6.

- If using a system Python 3 the virtualenv will no longer install system
Python 2.

- Spiny now supports having different requirements in setup.py for different
versions of Python.

- Not finding an executable for a specific environment is no longer a fatal
error, so you don't have to have all the supported versions installed.

----------------

- Added support for requirements.txt.

- Added parameters to skip executing setup.py.

- Added a setup-commands parameter to override how the virtualenv is made.

- The -e parameter now actually works.

- The information about the python execs is now cached. This speeds up
startup, a lot, fetching the Python environments goes from around 5
seconds to less than a tenth.

- A profile of each virtualenv is now saved in the virtualenv, containing
it's name, the full path of the Python exe, and the installed requirements.
A virtualenv will now only be updated if this has changed since the last run.
This also speeds up tests runs a lot in the typical case.

----------------

- Now runs under Python 3, PyPy, PyPy3, Jython.

- All output is now through logging, which enables you to select verbosity.

- Added --version, --verbose and --quiet options.

- Now use subprocess32 under Python 2.

- Will now run tests in parallell with multiprocessing. A 'max-processes'
option in the [spiny] section will allow you to cap the processes if
you don't want to max your computer. Otherwise it will use as many processes
as multiprocessing will report cpu's.

----------------

- Now prints a summary in the end.

- Regard more virtualenv tests as failures.

- Return 1 if not all tests succeeded.

- Fall back to setup.cfg is there is no spiny config file.

- Renamed spiny.conf to spiny.cfg for consistency.

- Made the configuration file optional.

- Spiny will now grep setup.py for Python version classifiers if no
environment configuration is found.

- If both Python X and Python X.Y is given as environments, it will
skip the tests for Python X, seeing as it is fulfilled by Python X.Y.

- The version specified in the [pythons] section now have preference.

- Setting a config option from the command line now works even if the section
doesn't exist.

- Spiny will now attempt to extract the test requirements and install them
into the virtualenv before running the tests, to avoid polluting the
project directory with .egg directories.
