.. _29943: https://bugs.python.org/issue29943

1.11

=====

• Support the modern standard types char16_t and char32_t.
  These work like wchar_t: they represent one unicode character, or
  when used as charN_t * or charN_t[] they represent a unicode
  string. The difference with wchar_t is that they have a known,
  fixed size. They should work at all places that used to work with
  wchar_t (please report an issue if I missed something). Note
  that with set_source(), you need to make sure that these types are
  actually defined by the C source you provide (if used in cdef()).

• Support the C99 types float _Complex and double _Complex.
  Note that libffi doesn't support them, which means that in the ABI
  mode you still cannot call C functions that take complex numbers
  directly as arguments or return type.

• Fixed a rare race condition when creating multiple FFI instances
  from multiple threads. (Note that you aren't meant to create many
  FFI instances: in inline mode, you should write ffi = cffi.FFI() at module level just after import cffi; and in
  out-of-line mode you don't instantiate FFI explicitly at all.)

• Windows: using callbacks can be messy because the CFFI internal error
  messages show up to stderr---but stderr goes nowhere in many
  applications. This makes it particularly hard to get started with the
  embedding mode. (Once you get started, you can at least use
  ffi.def_extern(onerror=...) and send the error logs where it
  makes sense for your application, or record them in log files, and so
  on.) So what is new in CFFI is that now, on Windows CFFI will try to
  open a non-modal MessageBox (in addition to sending raw messages to
  stderr). The MessageBox is only visible if the process stays alive:
  typically, console applications that crash close immediately, but that
  is also the situation where stderr should be visible anyway.

• Progress on support for callbacks in NetBSD__.

• Functions returning booleans would in some case still return 0 or 1
  instead of False or True. Fixed.

• ffi.gc()__ now takes an optional third parameter, which gives an
  estimate of the size (in bytes) of the object. So far, this is only
  used by PyPy, to make the next GC occur more quickly (issue 320).
  In the future, this might have an effect on CPython too (provided
  the CPython issue 31105 is addressed).

• Add a note to the documentation: the ABI mode gives function objects
  that are slower to call than the API mode does. For some reason it
  is often thought to be faster. It is not!

1.10.1

=======

1.10

=====

• Issue 295: use calloc() directly instead of
  PyObject_Malloc()+memset() to handle ffi.new() with a default
  allocator. Speeds up ffi.new(large-array) where most of the time
  you never touch most of the array.

• Some OS/X build fixes ("only with Xcode but without CLT").

• Improve a couple of error messages: when getting mismatched versions
  of cffi and its backend; and when calling functions which cannot be
  called with libffi because an argument is a struct that is "too
  complicated" (and not a struct pointer, which always works).

• Add support for some unusual compilers (non-msvc, non-gcc, non-icc,
  non-clang)

• Implemented the remaining cases for ffi.from_buffer. Now all
  buffer/memoryview objects can be passed. The one remaining check is
  against passing unicode strings in Python 2. (They support the buffer
  interface, but that gives the raw bytes behind the UTF16/UCS4 storage,
  which is most of the times not what you expect. In Python 3 this has
  been fixed and the unicode strings don't support the memoryview
  interface any more.)

• The C type _Bool or bool now converts to a Python boolean
  when reading, instead of the content of the byte as an integer. The
  potential incompatibility here is what occurs if the byte contains a
  value different from 0 and 1. Previously, it would just return it;
  with this change, CFFI raises an exception in this case. But this
  case means "undefined behavior" in C; if you really have to interface
  with a library relying on this, don't use bool in the CFFI side.
  Also, it is still valid to use a byte string as initializer for a
  bool[], but now it must only contain \x00 or \x01. As an
  aside, ffi.string() no longer works on bool[] (but it never
  made much sense, as this function stops at the first zero).

• ffi.buffer is now the name of cffi's buffer type, and
  ffi.buffer() works like before but is the constructor of that type.

• ffi.addressof(lib, "name") now works also in in-line mode, not
  only in out-of-line mode. This is useful for taking the address of
  global variables.

• Issue 255: cdata objects of a primitive type (integers, floats,
  char) are now compared and ordered by value. For example, <cdata 'int' 42> compares equal to 42 and <cdata 'char' b'A'>
  compares equal to b'A'. Unlike C, <cdata 'int' -1> does not
  compare equal to ffi.cast("unsigned int", -1): it compares
  smaller, because -1 < 4294967295.

• PyPy: ffi.new() and ffi.new_allocator()() did not record
  "memory pressure", causing the GC to run too infrequently if you call
  ffi.new() very often and/or with large arrays. Fixed in PyPy 5.7.

• Support in ffi.cdef() for numeric expressions with + or
  -. Assumes that there is no overflow; it should be fixed first
  before we add more general support for arbitrary arithmetic on
  constants.

1.9

====

• Structs with variable-sized arrays as their last field: now we track
  the length of the array after ffi.new() is called, just like we
  always tracked the length of ffi.new("int[]", 42). This lets us
  detect out-of-range accesses to array items. This also lets us
  display a better repr(), and have the total size returned by
  ffi.sizeof() and ffi.buffer(). Previously both functions
  would return a result based on the size of the declared structure
  type, with an assumed empty array. (Thanks andrew for starting this
  refactoring.)

• Add support in cdef()/set_source() for unspecified-length arrays
  in typedefs: typedef int foo_t[...];. It was already supported
  for global variables or structure fields.

• I turned in v1.8 a warning from cffi/model.py into an error:
  'enum xxx' has no values explicitly defined: refusing to guess which integer type it is meant to be (unsigned/signed, int/long). Now I'm
  turning it back to a warning again; it seems that guessing that the
  enum has size int is a 99%-safe bet. (But not 100%, so it stays
  as a warning.)

• Fix leaks in the code handling FILE * arguments. In CPython 3
  there is a remaining issue that is hard to fix: if you pass a Python
  file object to a FILE * argument, then os.dup() is used and
  the new file descriptor is only closed when the GC reclaims the Python
  file object---and not at the earlier time when you call close(),
  which only closes the original file descriptor. If this is an issue,
  you should avoid this automatic convertion of Python file objects:
  instead, explicitly manipulate file descriptors and call fdopen()
  from C (...via cffi).

1.8.3

======

• When passing a void * argument to a function with a different
  pointer type, or vice-versa, the cast occurs automatically, like in C.
  The same occurs for initialization with ffi.new() and a few other
  places. However, I thought that char * had the same
  property---but I was mistaken. In C you get the usual warning if you
  try to give a char * to a char ** argument, for example.
  Sorry about the confusion. This has been fixed in CFFI by giving for
  now a warning, too. It will turn into an error in a future version.

1.8.2

======

• Issue 283: fixed ffi.new() on structures/unions with nested
  anonymous structures/unions, when there is at least one union in
  the mix. When initialized with a list or a dict, it should now
  behave more closely like the { } syntax does in GCC.

1.8.1

======

• CPython 3.x: experimental: the generated C extension modules now use
  the "limited API", which means that, as a compiled .so/.dll, it should
  work directly on any version of CPython >= 3.2. The name produced by
  distutils is still version-specific. To get the version-independent
  name, you can rename it manually to NAME.abi3.so, or use the very
  recent setuptools 26.

• Added ffi.compile(debug=...), similar to python setup.py build --debug but defaulting to True if we are running a debugging
  version of Python itself.

1.8

====

• Removed the restriction that ffi.from_buffer() cannot be used on
  byte strings. Now you can get a char * out of a byte string,
  which is valid as long as the string object is kept alive. (But
  don't use it to modify the string object! If you need this, use
  bytearray or other official techniques.)

• PyPy 5.4 can now pass a byte string directly to a char *
  argument (in older versions, a copy would be made). This used to be
  a CPython-only optimization.

cryptography 2.0.3 -> 2.1.1

2.1

• FINAL DEPRECATION Python 2.6 support is deprecated, and will be removed
  in the next release of cryptography.
• BACKWARDS INCOMPATIBLE: Whirlpool, RIPEMD160, and
  UnsupportedExtension have been removed in accordance with our
  :doc:/api-stability policy.
• BACKWARDS INCOMPATIBLE: :attr:~cryptography.x509.DNSName.value,
  :attr:~cryptography.x509.RFC822Name.value, and
  :attr:~cryptography.x509.UniformResourceIdentifier.value will now return
  an :term:A-label string when parsing a certificate containing an
  internationalized domain name (IDN) or if the caller passed a :term:U-label
  to the constructor. See below for additional deprecations related to this
  change.
• Installing cryptography now requires pip 6 or newer.
• Deprecated passing :term:U-label strings to the
  :class:~cryptography.x509.DNSName,
  :class:~cryptography.x509.UniformResourceIdentifier, and
  :class:~cryptography.x509.RFC822Name constructors. Instead, users should
  pass values as :term:A-label strings with idna encoding if necessary.
  This change will not affect anyone who is not processing internationalized
  domains.
• Added support for
  :class:~cryptography.hazmat.primitives.ciphers.algorithms.ChaCha20. In
  most cases users should choose
  :class:~cryptography.hazmat.primitives.ciphers.aead.ChaCha20Poly1305
  rather than using this unauthenticated form.
• Added :meth:~cryptography.x509.CertificateRevocationList.is_signature_valid
  to :class:~cryptography.x509.CertificateRevocationList.
• Support :class:~cryptography.hazmat.primitives.hashes.BLAKE2b and
  :class:~cryptography.hazmat.primitives.hashes.BLAKE2s with
  :class:~cryptography.hazmat.primitives.hmac.HMAC.
• Added support for
  :class:~cryptography.hazmat.primitives.ciphers.modes.XTS mode for
  AES.
• Added support for using labels with
  :class:~cryptography.hazmat.primitives.asymmetric.padding.OAEP when using
  OpenSSL 1.0.2 or greater.
• Improved compatibility with NSS when issuing certificates from an issuer
  that has a subject with non-UTF8String string types.
• Add support for the :class:~cryptography.x509.DeltaCRLIndicator extension.
• Add support for the :class:~cryptography.x509.TLSFeature
  extension. This is commonly used for enabling OCSP Must-Staple in
  certificates.
• Add support for the :class:~cryptography.x509.FreshestCRL extension.

• pull request 450 <https://github.com/tox-dev/tox/pull/450>: Stop after the first installdeps and first testenv create hooks
  succeed. This changes the default behaviour of tox_testenv_create
  and tox_testenv_install_deps to not execute other registered hooks when
  the first hook returns a result that is not None.
  Thanks Anthony Sottile (asottile <https://github.com/asottile>).

New command line parameter: -a show all defined environments -
not just the ones defined in (or generated from) envlist.

New verbosity settings for -l and -a: show user defined descriptions
of the environments. This also works for generated environments from factors
by concatenating factor descriptions into a complete description.

Note that for backwards compatibility with scripts using the output of -l
it's output remains unchanged.

• add "alwayscopy" config option to instruct virtualenv to always copy
  files instead of symlinking. Thanks Igor Duarte Cardoso (igordcard <https://github.com/igordcard>_).

• pass setenv variables to setup.py during a usedevelop install.
  Thanks Eli Collins (eli-collins <https://github.com/eli-collins>_).

• replace all references to testrun.org with readthedocs ones.
  Thanks Oliver Bestwalter (obestwalter <https://github.com/obestwalter>_).

• fix 323 <https://github.com/tox-dev/tox/issues/323>_ by avoiding virtualenv14 is not used on py32
  (although we don't officially support py32).
  Thanks Jason R. Coombs (jaraco <https://github.com/jaraco>_).

• add Python 3.6 to envlist and CI.
  Thanks Andrii Soldatenko (andriisoldatenko <https://github.com/andriisoldatenko>_).

• fix glob resolution from TOX_TESTENV_PASSENV env variable
  Thanks Allan Feldman (a-feld <https://github.com/a-feld>_).

2.5.0

---

• slightly backward incompatible: fix 310 <https://github.com/tox-dev/tox/issues/310>: the {posargs} substitution
  now properly preserves the tox command line positional arguments. Positional
  arguments with spaces are now properly handled.
  NOTE: if your tox invocation previously used extra quoting for positional arguments to
  work around 310 <https://github.com/tox-dev/tox/issues/310>, you need to remove the quoting. Example:
  tox -- "'some string'" has to now be written simply as
  tox -- "some string"
  thanks holger krekel. You can set minversion = 2.5.0 in the [tox]
  section of tox.ini to make sure people using your tox.ini use the correct version.

• fix 359 <https://github.com/tox-dev/tox/issues/359>: add COMSPEC to default passenv on windows. Thanks
  anthrotype <https://github.com/anthrotype>.

• add support for py36 and py37 and add py36-dev and py37(nightly) to
  travis builds of tox. Thanks John Vandenberg.

• fix 348 <https://github.com/tox-dev/tox/issues/348>: add py2 and py3 as default environments pointing to
  "python2" and "python3" basepython executables. Also fix 347 <https://github.com/tox-dev/tox/issues/347> by
  updating the list of default envs in the tox basic example.
  Thanks Tobias McNulty.

• make "-h" and "--help-ini" options work even if there is no tox.ini,
  thanks holger krekel.

• add {:} substitution, which is replaced with os-specific path
  separator, thanks Lukasz Rogalski.

• fix 305 <https://github.com/tox-dev/tox/issues/305>_: downloadcache test env config is now ignored as pip-8
  does caching by default. Thanks holger krekel.

• output from install command in verbose (-vv) mode is now printed to console instead of
  being redirected to file, thanks Lukasz Rogalski

• fix 399 <https://github.com/tox-dev/tox/issues/399>_. Make sure {envtmpdir} is created if it doesn't exist at the
  start of a testenvironment run. Thanks Manuel Jacob.

• fix 316 <https://github.com/tox-dev/tox/issues/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. Thanks Lukasz Rogalski.

• fix 380 <https://github.com/tox-dev/tox/issues/380>_: properly perform substitution again. Thanks Ian
  Cordasco.

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. If this causes unforeseen problems it may be
  reverted in a bugfix release. Thanks Jason R. Coombs.

• fix 352 <https://github.com/tox-dev/tox/issues/352>_: prevent a configuration where envdir==toxinidir and
  refine docs to warn people about changing "envdir". Thanks Oliver Bestwalter and holger krekel.

• fix 375 <https://github.com/tox-dev/tox/issues/375>, fix 330 <https://github.com/tox-dev/tox/issues/330>: warn against tox-setup.py integration as
  "setup.py test" should really just test with the current interpreter. Thanks Ronny Pfannschmidt.

• fix 302 <https://github.com/tox-dev/tox/issues/302>_: allow cross-testenv substitution where we substitute
  with {x,y} generative syntax. Thanks Andrew Pashkin.

• fix 212 <https://github.com/tox-dev/tox/issues/212>_: allow escaping curly brace chars "{" and "}" if you need the
  chars "{" and "}" to appear in your commands or other ini values.
  Thanks John Vandenberg.

• addresses 66 <https://github.com/tox-dev/tox/issues/66>_: add --workdir option to override where tox stores its ".tox" directory
  and all of the virtualenv environment. Thanks Danring.

• introduce per-venv list_dependencies_command which defaults
  to "pip freeze" to obtain the list of installed packages.
  Thanks Ted Shaw, Holger Krekel.

• close 66 <https://github.com/tox-dev/tox/issues/66>_: add documentation to jenkins page on how to avoid
  "too long shebang" lines when calling pip from tox. Note that we
  can not use "python -m pip install X" by default because the latter
  adds the CWD and pip will think X is installed if it is there.
  "pip install X" does not do that.

• 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 275 <https://github.com/tox-dev/tox/issues/275>_: Introduce hooks tox_runtest_pre``` and tox_runtest_post`` which run before and after the tests of a venv,
  respectively. Thanks to Matthew Schinckel and itxaka serrano.

• fix 317 <https://github.com/tox-dev/tox/issues/317>_: evaluate minversion before tox config is parsed completely.
  Thanks Sachi King for the PR.

• added the "extras" environment option to specify the extras to use when doing the
  sdist or develop install. Contributed by Alex Grönholm.

• use pytest-catchlog instead of pytest-capturelog (latter is not
  maintained, uses deprecated pytest API)

2.3.2

---

• fix 314 <https://github.com/tox-dev/tox/issues/314>_: fix command invocation with .py scripts on windows.

• fix 279 <https://github.com/tox-dev/tox/issues/279>_: allow cross-section substitution when the value contains
  posargs. Thanks Sachi King for the PR.

2.3.1

---

• fix 294 <https://github.com/tox-dev/tox/issues/294>_: re-allow cross-section substitution for setenv.

2.3.0

---

• DEPRECATE use of "indexservers" in tox.ini. It complicates
  the internal code and it is recommended to rather use the
  devpi system for managing indexes for pip.

• fix 285 <https://github.com/tox-dev/tox/issues/285>_: 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. Thanks Nelfin for some tests and initial
  work on a PR.

• allow "" in commands. This is slightly incompatible with commands
  sections that used a comment after a "" line continuation.
  Thanks David Stanek for the PR.

• fix 289 <https://github.com/tox-dev/tox/issues/289>_: fix build_sphinx target, thanks Barry Warsaw.

• fix 252 <https://github.com/tox-dev/tox/issues/252>_: allow environment names with special characters.
  Thanks Julien Castets for initial PR and patience.

• 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. These hooks are experimental mainly because of
  the involved "venv" and session objects whose current public
  API is not fully guranteed.

• 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}. Thanks Florian Bruhin.

2.2.0

---

• fix 265 <https://github.com/tox-dev/tox/issues/265>_ 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). Thanks David Riddle.

• fix 246 <https://github.com/tox-dev/tox/issues/246>_: fix regression in config parsing by reordering
  such that {envbindir} can be used again in tox.ini. Thanks Olli Walsh.

• fix 99 <https://github.com/tox-dev/tox/issues/99>_: the {env:...} substitution now properly uses environment
  settings from the setenv section. Thanks Itxaka Serrano.

• fix 281 <https://github.com/tox-dev/tox/issues/281>_: make --force-dep work when urls are present in
  dependency configs. Thanks Glyph Lefkowitz for reporting.

• fix 174 <https://github.com/tox-dev/tox/issues/174>_: 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.
  Thanks Rebecka Gulliksson for the PR.

• fix 280 <https://github.com/tox-dev/tox/issues/280>_: properly skip missing interpreter if
  {envsitepackagesdir} is present in commands. Thanks BB:ceridwenv

2.1.1

---

• fix platform skipping for detox

• report skipped platforms as skips in the summary

2.1.0

---

• fix 258 <https://github.com/tox-dev/tox/issues/258>, fix 248 <https://github.com/tox-dev/tox/issues/248>, fix 253 <https://github.com/tox-dev/tox/issues/253>_: for non-test commands
  (installation, venv creation) we pass in the full invocation environment.

• remove experimental --set-home option which was hardly used and
  hackily implemented (if people want home-directory isolation we should
  figure out a better way to do it, possibly through a plugin)

• fix 259 <https://github.com/tox-dev/tox/issues/259>_: passenv is now a line-list which allows to intersperse
  comments. Thanks stefano-m.

• allow envlist to be a multi-line list, to intersperse comments
  and have long envlist settings split more naturally. Thanks Andre Caron.

• introduce a TOX_TESTENV_PASSENV setting which is honored
  when constructing the set of environment variables for test environments.
  Thanks Marc Abramowitz for pushing in this direction.

2.0.2

---

• fix 247 <https://github.com/tox-dev/tox/issues/247>_: tox now passes the LANG variable from the tox invocation
  environment to the test environment by default.

• add SYSTEMDRIVE into default passenv on windows to allow pip6 to work.
  Thanks Michael Krause.

2.0.1

---

• fix wheel packaging to properly require argparse on py26.

2.0.0

---

• (new) introduce environment variable isolation:
  tox now only passes the PATH and PIP_INDEX_URL variable from the tox
  invocation environment to the test environment and on Windows
  also SYSTEMROOT, PATHEXT, TEMP and TMP whereas
  on unix additionally TMPDIR is passed. If you need to pass
  through further environment variables you can use the new passenv setting,
  a space-separated list of environment variable names. Each name
  can make use of fnmatch-style glob patterns. All environment
  variables which exist in the tox-invocation environment will be copied
  to the test environment.

• a new --help-ini option shows all possible testenv settings and
  their defaults.

• (new) introduce a way to specify on which platform a testenvironment is to
  execute: the new per-venv "platform" setting allows to specify
  a regular expression which is matched against sys.platform.
  If platform is set and doesn't match the platform spec in the test
  environment the test environment is ignored, no setup or tests are attempted.

• (new) add per-venv "ignore_errors" setting, which defaults to False.
  If True, a non-zero exit code from one command will be ignored and
  further commands will be executed (which was the default behavior in tox <
  2.0). If False (the default), then a non-zero exit code from one command
  will abort execution of commands for that environment.

• show and store in json the version dependency information for each venv

• remove the long-deprecated "distribute" option as it has no effect these days.

• fix 233 <https://github.com/tox-dev/tox/issues/233>_: avoid hanging with tox-setuptools integration example. Thanks simonb.

• fix 120 <https://github.com/tox-dev/tox/issues/120>_: allow substitution for the commands section. Thanks
  Volodymyr Vitvitski.

• fix 235 <https://github.com/tox-dev/tox/issues/235>_: fix AttributeError with --installpkg. Thanks
  Volodymyr Vitvitski.

• tox has now somewhat pep8 clean code, thanks to Volodymyr Vitvitski.

• fix 240 <https://github.com/tox-dev/tox/issues/240>_: allow to specify empty argument list without it being
  rewritten to ".". Thanks Daniel Hahler.

• introduce experimental (not much documented yet) plugin system
  based on pytest's externalized "pluggy" system.
  See tox/hookspecs.py for the current hooks.

• introduce parser.add_testenv_attribute() to register an ini-variable
  for testenv sections. Can be used from plugins through the
  tox_add_option hook.

• rename internal files -- tox offers no external API except for the
  experimental plugin hooks, use tox internals at your own risk.

• DEPRECATE distshare in documentation

1.9.2

---

• backout ability that --force-dep substitutes name/versions in
  requirement files due to various issues.
  This fixes 228 <https://github.com/tox-dev/tox/issues/228>, fixes 230 <https://github.com/tox-dev/tox/issues/230>, fixes 231 <https://github.com/tox-dev/tox/issues/231>_
  which popped up with 1.9.1.

1.9.1

---

• use a file instead of a pipe for command output in "--result-json".
  Fixes some termination issues with python2.6.

• allow --force-dep to override dependencies in "-r" requirements
  files. Thanks Sontek for the PR.

• fix 227 <https://github.com/tox-dev/tox/issues/227>_: use "-m virtualenv" instead of "-mvirtualenv" to make
  it work with pyrun. Thanks Marc-Andre Lemburg.

1.9.0

---

• fix 193 <https://github.com/tox-dev/tox/issues/193>_: Remove --pre from the default install_command; by
  default tox will now only install final releases from PyPI for unpinned
  dependencies. Use pip_pre = true in a testenv or the --pre
  command-line option to restore the previous behavior.

• fix 199 <https://github.com/tox-dev/tox/issues/199>_: fill resultlog structure ahead of virtualenv creation

• refine determination if we run from Jenkins, thanks Borge Lanes.

• echo output to stdout when --report-json is used

• fix 11 <https://github.com/tox-dev/tox/issues/11>_: add a skip_install per-testenv setting which
  prevents the installation of a package. Thanks Julian Krause.

• fix 124 <https://github.com/tox-dev/tox/issues/124>_: ignore command exit codes; when a command has a "-" prefix,
  tox will ignore the exit code of that command

• fix 198 <https://github.com/tox-dev/tox/issues/198>_: fix broken envlist settings, e.g. {py26,py27}{-lint,}

• fix 191 <https://github.com/tox-dev/tox/issues/191>_: lessen factor-use checks

1.8.1

---

• fix 190 <https://github.com/tox-dev/tox/issues/190>_: allow setenv to be empty.

• allow escaping curly braces with "&quot;. Thanks Marc Abramowitz for the PR.

• allow "." names in environment names such that "py27-django1.7" is a
  valid environment name. Thanks Alex Gaynor and Alex Schepanovski.

• report subprocess exit code when execution fails. Thanks Marius
  Gedminas.

1.8.0

---

• new multi-dimensional configuration support. Many thanks to
  Alexander Schepanovski for the complete PR with docs.
  And to Mike Bayer and others for testing and feedback.

• fix 148 <https://github.com/tox-dev/tox/issues/148>_: remove "PYVENV_LAUNCHER" from os.environ when starting
  subprocesses. Thanks Steven Myint.

• fix 152 <https://github.com/tox-dev/tox/issues/152>_: set VIRTUAL_ENV when running test commands,
  thanks Florian Ludwig.

• better report if we can't get version_info from an interpreter
  executable. Thanks Floris Bruynooghe.

1.7.2

---

• fix 150 <https://github.com/tox-dev/tox/issues/150>_: parse {posargs} more like we used to do it pre 1.7.0.
  The 1.7.0 behaviour broke a lot of OpenStack projects.
  See PR85 and the issue discussions for (far) more details, hopefully
  resulting in a more refined behaviour in the 1.8 series.
  And thanks to Clark Boylan for the PR.

• fix 59 <https://github.com/tox-dev/tox/issues/59>_: add a config variable skip-missing-interpreters as well as
  command line option --skip-missing-interpreters which won't fail the
  build if Python interpreters listed in tox.ini are missing. Thanks
  Alexandre Conrad for PR104.

• fix 164 <https://github.com/tox-dev/tox/issues/164>_: better traceback info in case of failing test commands.
  Thanks Marc Abramowitz for PR92.

• support optional env variable substitution, thanks Morgan Fainberg
  for PR86.

• limit python hashseed to 1024 on Windows to prevent possible
  memory errors. Thanks March Schlaich for the PR90.

1.7.1

---

• fix 162 <https://github.com/tox-dev/tox/issues/162>_: don't list python 2.5 as compatibiliy/supported

• fix 158 <https://github.com/tox-dev/tox/issues/158>_ and fix 155 <https://github.com/tox-dev/tox/issues/155>_: windows/virtualenv properly works now:
  call virtualenv through "python -m virtualenv" with the same
  interpreter which invoked tox. Thanks Chris Withers, Ionel Maries Cristian.

1.7.0

---

• don't lookup "pip-script" anymore but rather just "pip" on windows
  as this is a pip implementation detail and changed with pip-1.5.
  It might mean that tox-1.7 is not able to install a different pip
  version into a virtualenv anymore.

• drop Python2.5 compatibility because it became too hard due
  to the setuptools-2.0 dropping support. tox now has no
  support for creating python2.5 based environments anymore
  and all internal special-handling has been removed.

• merged PR81: new option --force-dep which allows to
  override tox.ini specified dependencies in setuptools-style.
  For example "--force-dep 'django<1.6'" will make sure
  that any environment using "django" as a dependency will
  get the latest 1.5 release. Thanks Bruno Oliveria for
  the complete PR.

• merged PR125: tox now sets "PYTHONHASHSEED" to a random value
  and offers a "--hashseed" option to repeat a test run with a specific seed.
  You can also use --hashsheed=noset to instruct tox to leave the value
  alone. Thanks Chris Jerdonek for all the work behind this.

• fix 132 <https://github.com/tox-dev/tox/issues/132>_: removing zip_safe setting (so it defaults to false)
  to allow installation of tox
  via easy_install/eggs. Thanks Jenisys.

• fix 126 <https://github.com/tox-dev/tox/issues/126>: depend on virtualenv>=1.11.2 so that we can rely
  (hopefully) on a pip version which supports --pre. (tox by default
  uses to --pre). also merged in PR84 so that we now call "virtualenv"
  directly instead of looking up interpreters. Thanks Ionel Maries Cristian.
  This also fixes 140 <https://github.com/tox-dev/tox/issues/140>.

• fix 130 <https://github.com/tox-dev/tox/issues/130>_: you can now set install_command=easy_install {opts} {packages}
  and expect it to work for repeated tox runs (previously it only worked
  when always recreating). Thanks jenisys for precise reporting.

• fix 129 <https://github.com/tox-dev/tox/issues/129>_: tox now uses Popen(..., universal_newlines=True) to force
  creation of unicode stdout/stderr streams. fixes a problem on specific
  platform configs when creating virtualenvs with Python3.3. Thanks
  Jorgen Schäfer or investigation and solution sketch.

• fix 128 <https://github.com/tox-dev/tox/issues/128>_: enable full substitution in install_command,
  thanks for the PR to Ronald Evers

• rework and simplify "commands" parsing and in particular posargs
  substitutions to avoid various win32/posix related quoting issues.

• make sure that the --installpkg option trumps any usedevelop settings
  in tox.ini or

• introduce --no-network to tox's own test suite to skip tests
  requiring networks

• introduce --sitepackages to force sitepackages=True in all
  environments.

• fix 105 <https://github.com/tox-dev/tox/issues/105>_ -- don't depend on an existing HOME directory from tox tests.

1.6.1

---

• fix 119 <https://github.com/tox-dev/tox/issues/119>_: {envsitepackagesdir} is now correctly computed and has
  a better test to prevent regression.

• fix 116 <https://github.com/tox-dev/tox/issues/116>_: make 1.6 introduced behaviour of changing to a
  per-env HOME directory during install activities dependent
  on "--set-home" for now. Should re-establish the old behaviour
  when no option is given.

• fix 118 <https://github.com/tox-dev/tox/issues/118>_: correctly have two tests use realpath(). Thanks Barry
  Warsaw.

• fix test runs on environments without a home directory
  (in this case we use toxinidir as the homedir)

• fix 117 <https://github.com/tox-dev/tox/issues/117>_: python2.5 fix: don't use --insecure option because
  its very existence depends on presence of "ssl". If you
  want to support python2.5/pip1.3.1 based test environments you need
  to install ssl and/or use PIP_INSECURE=1 through setenv. section.

• fix 102 <https://github.com/tox-dev/tox/issues/102>_: change to {toxinidir} when installing dependencies.
  this allows to use relative path like in "-rrequirements.txt".

1.6.0

---

• fix 35 <https://github.com/tox-dev/tox/issues/35>_: add new EXPERIMENTAL "install_command" testenv-option to
  configure the installation command with options for dep/pkg install.
  Thanks Carl Meyer for the PR and docs.

• fix 91 <https://github.com/tox-dev/tox/issues/91>_: python2.5 support by vendoring the virtualenv-1.9.1
  script and forcing pip<1.4. Also the default [py25] environment
  modifies the default installer_command (new config option)
  to use pip without the "--pre" option which was introduced
  with pip-1.4 and is now required if you want to install non-stable
  releases. (tox defaults to install with "--pre" everywhere).

• during installation of dependencies HOME is now set to a pseudo
  location ({envtmpdir}/pseudo-home). If an index url was specified
  a .pydistutils.cfg file will be written with an index_url setting
  so that packages defining setup_requires dependencies will not
  silently use your HOME-directory settings or https://pypi.python.org/pypi.

• fix 1 <https://github.com/tox-dev/tox/issues/1>_: empty setup files are properly detected, thanks Anthon van
  der Neuth

• remove toxbootstrap.py for now because it is broken.

• fix 109 <https://github.com/tox-dev/tox/issues/109>_ and fix 111 <https://github.com/tox-dev/tox/issues/111>_: multiple "-e" options are now combined
  (previously the last one would win). Thanks Anthon van der Neut.

• add --result-json option to write out detailed per-venv information
  into a json report file to be used by upstream tools.

• add new config options usedevelop and skipsdist as well as a
  command line option --develop to install the package-under-test in develop mode.
  thanks Monty Tailor for the PR.

• always unset PYTHONDONTWRITEBYTE because newer setuptools doesn't like it

• if a HOMEDIR cannot be determined, use the toxinidir.

• refactor interpreter information detection to live in new
  tox/interpreters.py file, tests in tests/test_interpreters.py.

1.5.0

---

• fix 104 <https://github.com/tox-dev/tox/issues/104>_: use setuptools by default, instead of distribute,
  now that setuptools has distribute merged.

• make sure test commands are searched first in the virtualenv

• re-fix 2 <https://github.com/tox-dev/tox/issues/2>_ - add whitelist_externals to be used in [testenv*]
  sections, allowing to avoid warnings for commands such as make,
  used from the commands value.

• fix 97 <https://github.com/tox-dev/tox/issues/97>_ - allow substitutions to reference from other sections
  (thanks Krisztian Fekete)

• fix 92 <https://github.com/tox-dev/tox/issues/92>_ - fix {envsitepackagesdir} to actually work again

• show (test) command that is being executed, thanks
  Lukasz Balcerzak

• re-license tox to MIT license

• depend on virtualenv-1.9.1

• rename README.txt to README.rst to make bitbucket happier

1.4.3

---

• use pip-script.py instead of pip.exe on win32 to avoid the lock exe
  file on execution issue (thanks Philip Thiem)

• introduce -l|--listenv option to list configured environments
  (thanks Lukasz Balcerzak)

• fix downloadcache determination to work according to docs: Only
  make pip use a download cache if PIP_DOWNLOAD_CACHE or a
  downloadcache=PATH testenv setting is present. (The ENV setting
  takes precedence)

• fix 84 <https://github.com/tox-dev/tox/issues/84>_ - pypy on windows creates a bin not a scripts venv directory
  (thanks Lukasz Balcerzak)

• experimentally introduce --installpkg=PATH option to install a package
  rather than create/install an sdist package. This will still require
  and use tox.ini and tests from the current working dir (and not from the
  remote package).

• substitute {envsitepackagesdir} with the package installation
  directory (closes 72 <https://github.com/tox-dev/tox/issues/72>_) (thanks g2p)

• issue 70 <https://github.com/tox-dev/tox/issues/70>_ remove PYTHONDONTWRITEBYTECODE workaround now that
  virtualenv behaves properly (thanks g2p)

• merged tox-quickstart command, contributed by Marc Abramowitz, which
  generates a default tox.ini after asking a few questions

• fix 48 <https://github.com/tox-dev/tox/issues/48>_ - win32 detection of pypy and other interpreters that are on PATH
  (thanks Gustavo Picon)

• fix grouping of index servers, it is now done by name instead of
  indexserver url, allowing to use it to separate dependencies
  into groups even if using the same default indexserver.

• look for "tox.ini" files in parent dirs of current dir (closes 34 <https://github.com/tox-dev/tox/issues/34>_)

• the "py" environment now by default uses the current interpreter
  (sys.executable) make tox' own setup.py test execute tests with it
  (closes 46 <https://github.com/tox-dev/tox/issues/46>_)

• change tests to not rely on os.path.expanduser (closes 60 <https://github.com/tox-dev/tox/issues/60>),
  also make mock session return args[1:] for more precise checking (closes 61 <https://github.com/tox-dev/tox/issues/61>)
  thanks to Barry Warsaw for both.

1.4.2

---

• fix some tests which fail if /tmp is a symlink to some other place
• "python setup.py test" now runs tox tests via tox :)
  also added an example on how to do it for your project.

1.4.1

---

• fix 41 <https://github.com/tox-dev/tox/issues/41>_ better quoting on windows - you can now use "<" and ">" in
  deps specifications, thanks Chris Withers for reporting

1.4

---

• fix 26 <https://github.com/tox-dev/tox/issues/26>_ - no warnings on absolute or relative specified paths for commands
• fix 33 <https://github.com/tox-dev/tox/issues/33>_ - commentchars are ignored in key-value settings allowing
  for specifying commands like: python -c "import sys ; print sys"
  which would formerly raise irritating errors because the ";"
  was considered a comment
• tweak and improve reporting
• refactor reporting and virtualenv manipulation
  to be more accessible from 3rd party tools
• support value substitution from other sections
  with the {[section]key} syntax
• fix 29 <https://github.com/tox-dev/tox/issues/29>_ - correctly point to pytest explanation
  for importing modules fully qualified
• fix 32 <https://github.com/tox-dev/tox/issues/32>_ - use --system-site-packages and don't pass --no-site-packages
• add python3.3 to the default env list, so early adopters can test
• drop python2.4 support (you can still have your tests run on
• fix the links/checkout howtos in the docs
  python-2.4, just tox itself requires 2.5 or higher.

1.3

---

• fix: allow to specify wildcard filesystem paths when
  specifying dependencies such that tox searches for
  the highest version

• fix issue 21 <https://github.com/tox-dev/tox/issues/21>_: clear PIP_REQUIRES_VIRTUALENV which avoids
  pip installing to the wrong environment, thanks to bb's streeter

• make the install step honour a testenv's setenv setting
  (thanks Ralf Schmitt)

1.2

---

• remove the virtualenv.py that was distributed with tox and depend
  on >=virtualenv-1.6.4 (possible now since the latter fixes a few bugs
  that the inlining tried to work around)
• fix 10 <https://github.com/tox-dev/tox/issues/10>_: work around UnicodeDecodeError when invoking pip (thanks
  Marc Abramowitz)
• fix a problem with parsing {posargs} in tox commands (spotted by goodwill)
• fix the warning check for commands to be installed in testenvironment
  (thanks Michael Foord for reporting)

1.1

---

• fix 5 <https://github.com/tox-dev/tox/issues/5>_ - don't require argparse for python versions that have it
• fix 6 <https://github.com/tox-dev/tox/issues/6>_ - recreate virtualenv if installing dependencies failed
• fix 3 <https://github.com/tox-dev/tox/issues/3>_ - fix example on frontpage
• fix 2 <https://github.com/tox-dev/tox/issues/2>_ - warn if a test command does not come from the test
  environment
• fixed/enhanced: except for initial install always call "-U
  --no-deps" for installing the sdist package to ensure that a package
  gets upgraded even if its version number did not change. (reported on
  TIP mailing list and IRC)
• inline virtualenv.py (1.6.1) script to avoid a number of issues,
  particularly failing to install python3 environments from a python2
  virtualenv installation.
• rework and enhance docs for display on readthedocs.org

1.0

---

• move repository and toxbootstrap links to https://bitbucket.org/hpk42/tox
• fix 7 <https://github.com/tox-dev/tox/issues/7>_: introduce a "minversion" directive such that tox
  bails out if it does not have the correct version.
• fix 24 <https://github.com/tox-dev/tox/issues/24>_: introduce a way to set environment variables for
  for test commands (thanks Chris Rose)
• fix 22 <https://github.com/tox-dev/tox/issues/22>_: require virtualenv-1.6.1, obsoleting virtualenv5 (thanks Jannis Leidel)
  and making things work with pypy-1.5 and python3 more seamlessly
• toxbootstrap.py (used by jenkins build slaves) now follows the latest release of virtualenv
• fix 20 <https://github.com/tox-dev/tox/issues/20>_: document format of URLs for specifying dependencies
• fix 19 <https://github.com/tox-dev/tox/issues/19>_: substitute Hudson for Jenkins everywhere following the renaming
  of the project. NOTE: if you used the special [tox:hudson]
  section it will now need to be named [tox:jenkins].
• fix issue 23 / apply some ReST fixes
• change the positional argument specifier to use {posargs:} syntax and
  fix issues 15 <https://github.com/tox-dev/tox/issues/15>_ and 10 <https://github.com/tox-dev/tox/issues/10>_ by refining the argument parsing method (Chris Rose)
• remove use of inipkg lazy importing logic -
  the namespace/imports are anyway very small with tox.
• fix a fspath related assertion to work with debian installs which uses
  symlinks
• show path of the underlying virtualenv invocation and bootstrap
  virtualenv.py into a working subdir
• added a CONTRIBUTORS file

0.9

---

• fix pip-installation mixups by always unsetting PIP_RESPECT_VIRTUALENV
  (thanks Armin Ronacher)
• 1 <https://github.com/tox-dev/tox/issues/1>_: Add a toxbootstrap.py script for tox, thanks to Sridhar
  Ratnakumar
• added support for working with different and multiple PyPI indexservers.
• new option: -r|--recreate to force recreation of virtualenv
• depend on py>=1.4.0 which does not contain or install the py.test
  anymore which is now a separate distribution "pytest".
• show logfile content if there is an error (makes CI output
  more readable)

0.8

---

• work around a virtualenv limitation which crashes if
  PYTHONDONTWRITEBYTECODE is set.
• run pip/easy installs from the environment log directory, avoids
  naming clashes between env names and dependencies (thanks ronny)
• require a more recent version of py lib
• refactor and refine config detection to work from a single file
  and to detect the case where a python installation overwrote
  an old one and resulted in a new executable. This invalidates
  the existing virtualenvironment now.
• change all internal source to strip trailing whitespaces

0.7

---

• use virtualenv5 (my own fork of virtualenv3) for now to create python3
  environments, fixes a couple of issues and makes tox more likely to
  work with Python3 (on non-windows environments)

• add sitepackages option for testenv sections so that environments
  can be created with access to globals (default is not to have access,
  i.e. create environments with --no-site-packages.

• addressing 4 <https://github.com/tox-dev/tox/issues/4>_: always prepend venv-path to PATH variable when calling subprocesses

• fix 2 <https://github.com/tox-dev/tox/issues/2>_: exit with proper non-zero return code if there were
  errors or test failures.

• added unittest2 examples contributed by Michael Foord

• only allow 'True' or 'False' for boolean config values
  (lowercase / uppercase is irrelevant)

• recreate virtualenv on changed configurations

0.6

---

• fix OSX related bugs that could cause the caller's environment to get
  screwed (sorry). tox was using the same file as virtualenv for tracking
  the Python executable dependency and there also was confusion wrt links.
  this should be fixed now.

• fix long description, thanks Michael Foord

• initial release

==================
How to release tox

This matches the current model that can be summarized as this:

• tox has no long lived branches.

• Pull requests get integrated into master by members of the project when they feel confident that this could be part of the next release. Small fix ups might be done right after merge instead of disscussing back and forth to get minor problems fixed, to keep the workflow simple.

Normal releases: done from master when enough changes have accumaluted (whatever that means at any given point in time).

"Special" releases: (in seldom cases when master has moved on and is not in a state where a quick release should be done from that state): the current release tag is checked out, the necessary fixes are cherry picked and a package with a patch release increase is built from that state. This is not very clean but seems good enough at the moment as it does not happen very often. If it does happen more often, this needs some rethinking (and rather into the direction of making less buggy releases than complicating release development/release process).

HOWTO

Prerequisites

• Push rights for https://github.com/tox-dev/tox
• Release rights for https://pypi.org/project/tox/
• [optional] An account on https://devpi.net to upload the package under test
• A system with either tox + bash <https://www.gnu.org/software/bash/>_ or vagrant <https://github.com/tox-dev/tox/blob/master/Vagrantfile>_ (which contains tox + bash)
• Accountability: if you cut a release that breaks the CI builds of projects using tox, you are expected to fix this within a reasonable time frame (hours/days - not weeks/months) - if you don't feel quite capable of doing this yet, partner up with a more experienced member of the team and make sure they got your back if things break.

pypi/devpi configuration

note: this is in a state of flux due to changes in pypi infrastructure and depending whether devpi push can be used or not. Please keep this updated according to current process

Current process pypi upload packages from dist/ via twine.

If you want to use the scripts in task/ you need a .pypirc with a correctly configured pypi section (see below). Otherwise just upload the release package which ever way you see fit.

[pypi] section in .pypirc should look somehow like this:

.. code-block:: ini

[pypi]
;repository=https://pypi.python.org/pypi
;repository=https://upload.pypi.io/legacy/
username=<your username>
password=<your password>

to get info about the workflow invoke::

tox -e tpra

and you get a help message like::

workflow: /home/oliver/work/tox/tox/tasks/pra.sh <command> [arg]
prep <version>
upload <devpi username>
devpi-cloud-test <devpi username> (optional)
release

... and go from there.

The script executes the necessary actions and asks for confirmation to go on before committing or tagging stuff. So there is no danger to dry run the process, as long as you don't call the final release command with packages in your dist/* - if you managed to screw things up entirely there is always git reset --hard HEAD at your service.

note: **prais short for "personal release assistant" :) - if you want to see what this involves or rather do everything by hand, please read the scripts intasks <https://github.com/tox-dev/tox/tree/master/tasks&gt;`_.

Get started with devpi cloud test

Configure a repository as per-instructions on devpi-cloud-test_ to test the package on Travis_ and AppVeyor_. All test environments should pass.

If you don't want or can't do the cloud test step ...

Run from multiple machines::

devpi use https://devpi.net/&lt;your devpi user name>/dev
devpi test tox==<VERSION>

Check that tests pass for relevant combinations with::

devpi list tox

.. _devpi-cloud-test: https://github.com/obestwalter/devpi-cloud-test
.. _AppVeyor: https://www.appveyor.com/
.. _Travis: https://travis-ci.org

Once you have closed this pull request, I'll create separate pull requests for every update as soon as I find them.

That's it for now!
