py-tox: updated to 3.0.0

3.0.0:
Bugfixes
Write directly to stdout buffer if possible to prevent str vs bytes issues
fix 672 reporting to json file when skip-missing-interpreters option is used
avoid Requested Python version (X.Y) not installed stderr output when a Python \ 
environment is looked up using the py Python launcher on Windows and the \ 
environment is not found installed on the system
Fixed an issue where invocation of tox from the Python package, where invocation \ 
errors (failed actions) occur results in a change in the sys.stdout stream \ 
encoding in Python 3.x. New behaviour is that sys.stdout is reset back to its \ 
original encoding after invocation errors
The reading of command output sometimes failed with IOError: [Errno 0] Error on \ 
Windows, this was fixed by using a simpler method to update the read buffers.
(only affected rc releases) fix up tox.cmdline to be callable without args
(only affected rc releases) Revert breaking change of tox.cmdline not callable \ 
with no args
(only affected rc releases) fix 755 by reverting the cmdline import to the old \ 
location and changing the entry point instead

Features
tox displays exit code together with InvocationError
Hint for possible signal upon InvocationError, on posix systems
Add a -q option to progressively silence tox’s output. For each time you \ 
specify -q to tox, the output provided by tox reduces. This option allows you to \ 
see only your command output without the default verbosity of what tox is doing. \ 
This also counter-acts usage of -v. For example, running tox -v -q ... will \ 
provide you with the default verbosity. tox -vv -q is equivalent to tox -v. By \ 
@sigmavirus24
add support for negated factor conditions, e.g. !dev: production_log
Headings like installed: <packages> will not be printed if there is no \ 
output to display after the :, unless verbosity is set. By @cryvate
Allow spaces in command line options to pip in deps. Where previously only \ 
deps=-rreq.txt and deps=--requirement=req.txt worked, now also deps=-r req.txt \ 
and deps=--requirement req.txt work
drop Python 2.6 and 3.3 support: setuptools dropped supporting these, and as we \ 
depend on it we’ll follow up with doing the same (use tox <= 2.9.1 if you \ 
still need this support)
Add tox_runenvreport as a possible plugin, allowing the overriding of the \ 
default behaviour to execute a command to get the installed packages within a \ 
virtual environment
Forward PROCESSOR_ARCHITECTURE by default on Windows to fix platform.machine().

Log message:
Update devel/py-tox to 2.7.0.

2.7.0
-----

- #p450: Stop after the first installdeps and first testenv create hooks
  succeed.
- #271 and #464: Improve environment information for users.
- #464: Fix incorrect egg-info location for modified package_dir in setup.py.
- #431: Add 'LANGUAGE' to default passed environment variables.
- #455: Add a Vagrantfile with a customized Arch Linux box for local testing.
- #454: Revert #407, empty commands is not treated as an error.
- #446: (infrastructure) Travis CI tests for tox now also run on OS X now.

2.6.0
-----

- add "alwayscopy" config option to instruct virtualenv to always copy
  files instead of symlinking.
- pass setenv variables to setup.py during a usedevelop install.
- replace all references to testrun.org with readthedocs ones.
- fix #323 by avoiding virtualenv14 is not used on py32
- add Python 3.6 to envlist and CI.
- fix glob resolution from TOX_TESTENV_PASSENV env variable

2.5.0
-----

- slightly backward incompatible: fix issue310: the {posargs} substitution
  now properly preserves the tox command line positional arguments. Positional
  arguments with spaces are now properly handled.
- fix #359: add COMSPEC to default passenv on windows.
- add support for py36 and py37 and add py36-dev and py37(nightly) to
  travis builds of tox.
- fix #348: add py2 and py3 as default environments pointing to
  "python2" and "python3" basepython executables.  Also fix \ 
#347 by
  updating the list of default envs in the tox basic example.
- make "-h" and "--help-ini" options work even if there is \ 
no tox.ini,
- add {:} substitution, which is replaced with os-specific path
  separator
- fix #305: ``downloadcache`` test env config is now ignored as pip-8
  does caching by default.
- output from install command in verbose (-vv) mode is now printed to console \ 
instead of
  being redirected to file
- fix #399.  Make sure {envtmpdir} is created if it doesn't exist at the
  start of a testenvironment run.
- fix #316: Lack of commands key in ini file is now treated as an error.
  Reported virtualenv status is 'nothing to do' instead of 'commands
  succeeded', with relevant error message displayed.

2.4.1
-----

- fix issue380: properly perform substitution again.

2.4.0
-----

- remove PYTHONPATH from environment during the install phase because a
  tox-run should not have hidden dependencies and the test commands will also
  not see a PYTHONPATH.
- fix issue352: prevent a configuration where envdir==toxinidir and
  refine docs to warn people about changing "envdir".
- fix issue375, fix issue330: warn against tox-setup.py integration as
  "setup.py test" should really just test with the current interpreter.
- fix issue302: allow cross-testenv substitution where we substitute
  with ``{x,y}`` generative syntax.
- fix issue212: allow escaping curly brace chars "\{" and \ 
"\}" if you need the
  chars "{" and "}" to appear in your commands or other ini \ 
values.
- addresses issue66: add --workdir option to override where tox stores its \ 
".tox" directory
  and all of the virtualenv environment.
- introduce per-venv list_dependencies_command which defaults
  to "pip freeze" to obtain the list of installed packages.
- close issue66: add documentation to jenkins page on how to avoid
  "too long shebang" lines when calling pip from tox.
- new list_dependencies_command to influence how tox determines
  which dependencies are installed in a testenv.
- (experimental) New feature: When a search for a config file fails, tox tries \ 
loading
  setup.cfg with a section prefix of "tox".
- fix issue275: Introduce hooks ``tox_runtest_pre``` and
  ``tox_runtest_post`` which run before and after the tests of a venv,
  respectively.
- fix issue317: evaluate minversion before tox config is parsed completely.
- added the "extras" environment option to specify the extras to use \ 
when doing the
  sdist or develop install.
- use pytest-catchlog instead of pytest-capturelog (latter is not
  maintained, uses deprecated pytest API)

2.3.2
-----

- fix issue314: fix command invocation with .py scripts on windows.
- fix issue279: allow cross-section substitution when the value contains
  posargs.

2.3.1
-----

- fix issue294: re-allow cross-section substitution for setenv.

2.3.0
-----

- DEPRECATE use of "indexservers" in tox.ini.
- fix issue285: make setenv processing fully lazy to fix regressions
  of tox-2.2.X and so that we can now have testenv attributes like
  "basepython" depend on environment variables that are set in
  a setenv section.
- allow "#" in commands.
- fix issue289: fix build_sphinx target
- fix issue252: allow environment names with special characters.
- introduce experimental tox_testenv_create(venv, action) and
  tox_testenv_install_deps(venv, action) hooks to allow
  plugins to do additional work on creation or installing
  deps.
- internal: push some optional object creation into tests because
  tox core doesn't need it.

2.2.1
-----

- fix bug where {envdir} substitution could not be used in setenv
  if that env value is then used in {basepython}.

2.2.0
-----

- fix issue265 and add LD_LIBRARY_PATH to passenv on linux by default
  because otherwise the python interpreter might not start up in
  certain configurations (redhat software collections).
- fix issue246: fix regression in config parsing by reordering
  such that {envbindir} can be used again in tox.ini.
- fix issue99: the {env:...} substitution now properly uses environment
  settings from the ``setenv`` section.
- fix issue281: make --force-dep work when urls are present in
  dependency configs.
- fix issue174: add new ``ignore_outcome`` testenv attribute which
  can be set to True in which case it will produce a warning instead
  of an error on a failed testenv command outcome.
- fix issue280: properly skip missing interpreter if
  {envsitepackagesdir} is present in commands.

Log message:
Import py-tox-2.1.1 as devel/py-tox.

Tox is a generic virtualenv management and test command line tool
you can use for:

* checking your package installs correctly with different Python
  versions and interpreters
* running your tests in each of the environments, configuring your
  test tool of choice
* acting as a frontend to Continuous Integration servers, greatly
  reducing boilerplate and merging CI and shell-based testing.
