Changelogs

attrs 15.1.0 -> 17.2.0

17.2.0

Backward-incompatible changes:
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

none

Deprecations:
^^^^^^^^^^^^^

none

Changes:
^^^^^^^^

Validators are hashable again.
Note that validators may become frozen in the future, pending availability of no-overhead frozen classes.
192 <https://github.com/python-attrs/attrs/issues/192>_

17.1.0

To encourage more participation, the project has also been moved into a dedicated GitHub organization <https://github.com/python-attrs/>_ and everyone is most welcome to join!

attrs also has a logo now!

.. image:: http://www.attrs.org/en/latest/_static/attrs_logo.png
:alt: attrs logo

Backward-incompatible changes:
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

attrs will set the __hash__() method to None by default now.
The way hashes were handled before was in conflict with Python's specification <https://docs.python.org/3/reference/datamodel.htmlobject.__hash__>.
This may break some software although this breakage is most likely just surfacing of latent bugs.
You can always make attrs create the __hash__() method using attr.s(hash=True).
See 136 for the rationale of this change.

.. warning::

Please do not upgrade blindly and do test your software!
Especially if you use instances as dict keys or put them into sets!

Correspondingly, attr.ib's hash argument is None by default too and mirrors the cmp argument as it should.

Deprecations:
^^^^^^^^^^^^^

attr.assoc() is now deprecated in favor of attr.evolve() and will stop working in 2018.

Changes:
^^^^^^^^

Fix default hashing behavior.
Now hash mirrors the value of cmp and classes are unhashable by default.
136_
142 <https://github.com/python-attrs/attrs/issues/142>_

Added attr.evolve() that, given an instance of an attrs class and field changes as keyword arguments, will instantiate a copy of the given instance with the changes applied.
evolve() replaces assoc(), which is now deprecated.
evolve() is significantly faster than assoc(), and requires the class have an initializer that can take the field values as keyword arguments (like attrs itself can generate).
116 <https://github.com/python-attrs/attrs/issues/116>_
124 <https://github.com/python-attrs/attrs/pull/124>_
135 <https://github.com/python-attrs/attrs/pull/135>_

FrozenInstanceError is now raised when trying to delete an attribute from a frozen class.
118 <https://github.com/python-attrs/attrs/pull/118>_

Frozen-ness of classes is now inherited.
128 <https://github.com/python-attrs/attrs/pull/128>_

__attrs_post_init__() is now run if validation is disabled.
130 <https://github.com/python-attrs/attrs/pull/130>_

Added attr.validators.in_(options) that, given the allowed options, checks whether the attribute value is in it.
This can be used to check constants, enums, mappings, etc.
181 <https://github.com/python-attrs/attrs/pull/181>_

Added attr.validators.and_() that composes multiple validators into one.
161 <https://github.com/python-attrs/attrs/issues/161>_

For convenience, the validator argument of attr.s now can take a list of validators that are wrapped using and_().
138 <https://github.com/python-attrs/attrs/issues/138>_

Accordingly, attr.validators.optional() now can take a list of validators too.
161 <https://github.com/python-attrs/attrs/issues/161>_

Validators can now be defined conveniently inline by using the attribute as a decorator.
Check out the examples <http://www.attrs.org/en/stable/examples.htmlvalidators>_ to see it in action!
143 <https://github.com/python-attrs/attrs/issues/143>_

attr.Factory() now has a takes_self argument that makes the initializer to pass the partially initialized instance into the factory.
In other words you can define attribute defaults based on other attributes.
165_
189 <https://github.com/python-attrs/attrs/issues/189>_

Default factories can now also be defined inline using decorators.
They are always passed the partially initialized instance.
165_

Conversion can now be made optional using attr.converters.optional().
105 <https://github.com/python-attrs/attrs/issues/105>_
173 <https://github.com/python-attrs/attrs/pull/173>_

attr.make_class() now accepts the keyword argument bases which allows for subclassing.
152 <https://github.com/python-attrs/attrs/pull/152>_

Metaclasses are now preserved with slots=True.
155 <https://github.com/python-attrs/attrs/pull/155>_

16.3.0

Changes:
^^^^^^^^

Attributes now can have user-defined metadata which greatly improves attrs's extensibility.
96 <https://github.com/python-attrs/attrs/pull/96>_

Allow for a __attrs_post_init__() method that -- if defined -- will get called at the end of the attrs-generated __init__() method.
111 <https://github.com/python-attrs/attrs/pull/111>_

Added attr.s(str=True) that will optionally create a __str__() method that is identical to __repr__().
This is mainly useful with Exception\ s and other classes that rely on a useful __str__() implementation but overwrite the default one through a poor own one.
Default Python class behavior is to use __repr__() as __str__() anyways.

If you tried using attrs with Exception\ s and were puzzled by the tracebacks: this option is for you.

__name__ is not overwritten with __qualname__ for attr.s(slots=True) classes anymore.
99 <https://github.com/python-attrs/attrs/issues/99>_

16.2.0

Changes:
^^^^^^^^

Added attr.astuple() that -- similarly to attr.asdict() -- returns the instance as a tuple.
77 <https://github.com/python-attrs/attrs/issues/77>_

Converts now work with frozen classes.
76 <https://github.com/python-attrs/attrs/issues/76>_

Instantiation of attrs classes with converters is now significantly faster.
80 <https://github.com/python-attrs/attrs/pull/80>_

Pickling now works with __slots__ classes.
81 <https://github.com/python-attrs/attrs/issues/81>_

attr.assoc() now works with __slots__ classes.
84 <https://github.com/python-attrs/attrs/issues/84>_

The tuple returned by attr.fields() now also allows to access the Attribute instances by name.
Yes, we've subclassed tuple so you don't have to!
Therefore attr.fields(C).x is equivalent to the deprecated C.x and works with __slots__ classes.
88 <https://github.com/python-attrs/attrs/issues/88>_

16.1.0

Backward-incompatible changes:
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

All instances where function arguments were called cl have been changed to the more Pythonic cls.
Since it was always the first argument, it's doubtful anyone ever called those function with in the keyword form.
If so, sorry for any breakage but there's no practical deprecation path to solve this ugly wart.

Deprecations:
^^^^^^^^^^^^^

Accessing Attribute instances on class objects is now deprecated and will stop working in 2017.
If you need introspection please use the __attrs_attrs__ attribute or the attr.fields() function that carry them too.
In the future, the attributes that are defined on the class body and are usually overwritten in your __init__ method are simply removed after attr.s has been applied.

This will remove the confusing error message if you write your own __init__ and forget to initialize some attribute.
Instead you will get a straightforward AttributeError.
In other words: decorated classes will work more like plain Python classes which was always attrs's goal.

The serious business aliases attr.attributes and attr.attr have been deprecated in favor of attr.attrs and attr.attrib which are much more consistent and frankly obvious in hindsight.
They will be purged from documentation immediately but there are no plans to actually remove them.

Changes:
^^^^^^^^

attr.asdict()\ 's dict_factory arguments is now propagated on recursion.
45 <https://github.com/python-attrs/attrs/issues/45>_

attr.asdict(), attr.has() and attr.fields() are significantly faster.
48 <https://github.com/python-attrs/attrs/issues/48>_
51 <https://github.com/python-attrs/attrs/issues/51>_

Add attr.attrs and attr.attrib as a more consistent aliases for attr.s and attr.ib.

Add frozen option to attr.s that will make instances best-effort immutable.
60 <https://github.com/python-attrs/attrs/issues/60>_

attr.asdict() now takes retain_collection_types as an argument.
If True, it does not convert attributes of type tuple or set to list.
69 <https://github.com/python-attrs/attrs/issues/69>_

16.0.0

Backward-incompatible changes:
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Python 3.3 and 2.6 aren't supported anymore.
They may work by chance but any effort to keep them working has ceased.

The last Python 2.6 release was on October 29, 2013 and isn't supported by the CPython core team anymore.
Major Python packages like Django and Twisted dropped Python 2.6 a while ago already.

Python 3.3 never had a significant user base and wasn't part of any distribution's LTS release.

Changes:
^^^^^^^^

__slots__ have arrived!
Classes now can automatically be slots <https://docs.python.org/3.5/reference/datamodel.htmlslots>-style (and save your precious memory) just by passing slots=True.
35 <https://github.com/python-attrs/attrs/issues/35>

Allow the case of initializing attributes that are set to init=False.
This allows for clean initializer parameter lists while being able to initialize attributes to default values.
32 <https://github.com/python-attrs/attrs/issues/32>_

attr.asdict() can now produce arbitrary mappings instead of Python dict\ s when provided with a dict_factory argument.
40 <https://github.com/python-attrs/attrs/issues/40>_

Multiple performance improvements.

15.2.0

Changes:
^^^^^^^^

Added a convert argument to attr.ib, which allows specifying a function to run on arguments.
This allows for simple type conversions, e.g. with attr.ib(convert=int).
26 <https://github.com/python-attrs/attrs/issues/26>_

Speed up object creation when attribute validators are used.
28 <https://github.com/python-attrs/attrs/issues/28>_

thanks Xavier Fernandez)

0.28.0

======

Fix file modes in archive (Issue 154)

0.27.0

======

Support forcing a platform tag using --plat-name on pure-Python wheels, as
well as nonstandard platform tags on non-pure wheels (Pull Request 60, Issue
144, thanks Andrés Díaz)

Add SOABI tags to platform-specific wheels built for Python 2.X (Pull Request
55, Issue 63, Issue 101)

Support reproducible wheel files, wheels that can be rebuilt and will hash to
the same values as previous builds (Pull Request 52, Issue 143, thanks
Barry Warsaw)

Support for changes in keyring >= 8.0 (Pull Request 61, thanks Jason R.
Coombs)

Use the file context manager when checking if dependency_links.txt is empty,
fixes problems building wheels under PyPy on Windows (Issue 150, thanks
Cosimo Lupo)

Added the PyPA Code of Conduct (Pull Request 56)

0.26.0

======

Fix multiple entrypoint comparison failure on Python 3 (Issue 148)

0.25.0

======

Add Python 3.5 to tox configuration

Deterministic (sorted) metadata

Fix tagging for Python 3.5 compatibility

Support py2-none-'arch' and py3-none-'arch' tags

Treat data-only wheels as pure

Write to temporary file and rename when using wheel install --force

0.24.0

======

The python tag used for pure-python packages is now .pyN (major version
only). This change actually occurred in 0.23.0 when the --python-tag
option was added, but was not explicitly mentioned in the changelog then.

wininst2wheel and egg2wheel removed. Use "wheel convert [archive]"
instead.

Wheel now supports setuptools style conditional requirements via the
extras_require={} syntax. Separate 'extra' names from conditions using
the : character. Wheel's own setup.py does this. (The empty-string
extra is the same as install_requires.) These conditional requirements
should work the same whether the package is installed by wheel or
by setup.py.

3.1.0

You can view the 3.1.0 milestone_ on GitLab for more details.

Add --bug-report flag to make issue reporters' lives easier.

Collect configuration files from the current directory when using our Git
hook. (See also GitLab210, GitLab218, GitLab223_)

Avoid unhandled exceptions when dealing with SyntaxErrors. (See also
GitLab214, GitLab238)

Exit early if the value for --diff is empty. (See also GitLab226_)

Handle empty --stdin-display-name values. (See also GitLab235_)

Properly report the column number of Syntax Errors. We were assuming that
all reports of column numbers were 0-indexed, however, SyntaxErrors report
the column number as 1-indexed. This caused us to report a column number
that was 1 past the actual position. Further, when combined with
SyntaxErrors that occur at a newline, this caused the position to be
visually off by two. (See also GitLab237_)

Fix the behaviour of --enable-extensions. Previously, items specified
here were still ignored due to the fact that the off-by-default extension
codes were being left in the ignore list. (See also GitLab239_)

Fix problems around --select and --ignore behaviour that prevented
codes that were neither explicitly selected nor explicitly ignored from
being reported. (See also GitLab242_)

Truly be quiet when the user specifies -q one or more times. Previously,
we were showing the if the user specified -q and --show-source. We
have fixed this bug. (See also GitLab245_)

Add new File Processor attribute, previous_unindented_logical_line to
accommodate pycodestyle 2.1.0. (See also GitLab246_)

When something goes wrong, exit non-zero. (See also GitLab248,
GitLab209)

Add --tee as an option to allow use of --output-file and printing to
standard out.

Allow the git plugin to actually be lazy when collecting files.

Allow for pycodestyle 2.1 series and pyflakes 1.3 series.

(See also this Python bug report_)

Raise exception when entry_point in plugin not callable.
This raises an informative error when a plugin fails to load because its
entry_point is not callable, which can happen with a plugin which is buggy or
not updated for the current version of flake8. This is nicer than raising a
PicklingError about failing to pickle a module (See also GitLab164_)

Fix noqa comments followed by a : and explanation broken by
3.0.0 (See also GitLab178_)

Always open our output file in append mode so we do not overwrite log
messages. (See also GitLab193_)

When normalizing path values read from configuration, keep in context the
directory where the configuration was found so that relative paths work.
(See also GitLab194_)

3.0.0

Rewrite our documentation from scratch! (http://flake8.pycqa.org)

Drop explicit support for Pythons 2.6, 3.2, and 3.3.

Remove dependence on pep8/pycodestyle for file processing, plugin
dispatching, and more. We now control all of this while keeping backwards
compatibility.

--select and --ignore can now both be specified and try to find the
most specific rule from each. For example, if you do --select E --ignore E123 then we will report everything that starts with E except for
E123. Previously, you would have had to do --ignore E123,F,W which
will also still work, but the former should be far more intuitive.

Add support for in-line noqa comments to specify only the error
codes to be ignored, e.g., noqa: E123,W503

Add entry-point for formatters as well as a base class that new formatters
can inherit from. See the documentation for more details.

Add detailed verbose output using the standard library logging module.

Enhance our usage of optparse for plugin developers by adding new parameters
to the add_option that plugins use to register new options.

Update --install-hook to require the name of version control system hook
you wish to install a Flake8.

Stop checking sub-directories more than once via the setuptools command

When passing a file on standard-in, allow the caller to specify
--stdin-display-name so the output is properly formatted

The Git hook now uses sys.executable to format the shebang line.
This allows Flake8 to install a hook script from a virtualenv that points to
that virtualenv's Flake8 as opposed to a global one (without the virtualenv
being sourced).

Print results in a deterministic and consistent ordering when used with
multiprocessing

When using --count, the output is no longer written to stderr.

AST plugins can either be functions or classes and all plugins can now
register options so long as there are callable attributes named as we
expect.

Stop forcibly re-adding .tox, .eggs, and *.eggs to
--exclude. Flake8 2.x started always appending those three patterns
to any exclude list (including the default and any user supplied list).
Flake8 3 has stopped adding these in, so you may see errors when upgrading
due to these patterns no longer being forcibly excluded by default if you
have your own exclude patterns specified.

To fix this, add the appropriate patterns to your exclude patterns list.

will use that package name

Improvement Allow for Windows users on select versions of Python to
use --jobs and multiprocessing

pull request 553 <https://github.com/tox-dev/tox/pull/553>: Add an XFAIL test to reproduce upstream bug 203 <https://github.com/tox-dev/tox/issues/203>. Thanks
Bartolomé Sánchez Salado (bartsanchez <https://github.com/bartsanchez>_).

pull request 556 <https://github.com/tox-dev/tox/pull/556>: Report more meaningful errors on why virtualenv creation failed. Thanks vlaci <https://github.com/vlaci>.
Also thanks to Igor Sadchenko (igor-sadchenko <https://github.com/igor-sadchenko>_) for pointing out a problem with that PR
before it hit the masses ☺

pull request 575 <https://github.com/tox-dev/tox/pull/575>_: Add announcement doc to end all announcement docs

pull request 580 <https://github.com/tox-dev/tox/pull/580>: Do not ignore Sphinx warnings anymore. Thanks Bernát Gábor (gaborbernat <https://github.com/gaborbernat>).

pull request 585 <https://github.com/tox-dev/tox/pull/585>: Expand documentation to explain pass through of flags from deps to pip
(e.g. -rrequirements.txt, -cconstraints.txt). Thanks Alexander Loechel (loechel <https://github.com/loechel>).

pull request 588 <https://github.com/tox-dev/tox/pull/588>_: Run pytest wit xfail_strict and adapt affected tests.

2.7.0

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>).

271 <https://github.com/tox-dev/tox/issues/271>_ and 464 <https://github.com/tox-dev/tox/issues/464>_: Improve environment information for users.

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.

Thanks Bernát Gábor (gaborbernat <https://github.com/gaborbernat>_).

464 <https://github.com/tox-dev/tox/issues/464>: Fix incorrect egg-info location for modified package_dir in setup.py.
Thanks Selim Belhaouane (selimb <https://github.com/selimb>).

431 <https://github.com/tox-dev/tox/issues/431>: Add 'LANGUAGE' to default passed environment variables.
Thanks Paweł Adamczak (pawelad <https://github.com/pawelad>).

455 <https://github.com/tox-dev/tox/issues/455>: Add a Vagrantfile with a customized Arch Linux box for local testing.
Thanks Oliver Bestwalter (obestwalter <https://github.com/obestwalter>).

454 <https://github.com/tox-dev/tox/issues/454>: Revert pull request 407 <https://github.com/tox-dev/tox/pull/407>, empty commands is not treated as an error.
Thanks Anthony Sottile (asottile <https://github.com/asottile>_).

446 <https://github.com/tox-dev/tox/issues/446>: (infrastructure) Travis CI tests for tox now also run on OS X now.
Thanks Jason R. Coombs (jaraco <https://github.com/jaraco>).

2.6.0

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.

2.4.1

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

coverage 4.0 -> 4.4.1

4.4.1

No code changes: just corrected packaging for Python 2.7 Linux wheels.

.. _changes_44:

4.4

Reports could produce the wrong file names for packages, reporting pkg.py
instead of the correct pkg/__init__.py. This is now fixed. Thanks, Dirk
Thomas.

XML reports could produce <source> and <class> lines that together
didn't specify a valid source file path. This is now fixed. (issue 526_)

Namespace packages are no longer warned as having no code. (issue 572_)

Code that uses sys.settrace(sys.gettrace()) in a file that wasn't being
coverage-measured would prevent correct coverage measurement in following
code. An example of this was running doctests programmatically. This is now
fixed. (issue 575_)

Errors printed by the coverage command now go to stderr instead of
stdout.

Running coverage xml in a directory named with non-ASCII characters would
fail under Python 2. This is now fixed. (issue 573_)

4.4b1

Some warnings can now be individually disabled. Warnings that can be
disabled have a short name appended. The [run] disable_warnings setting
takes a list of these warning names to disable. Closes both issue 96_ and
issue 355_.

The XML report now includes attributes from version 4 of the Cobertura XML
format, fixing issue 570_.

In previous versions, calling a method that used collected data would prevent
further collection. For example, save(), report(), html_report(), and
others would all stop collection. An explicit start() was needed to get it
going again. This is no longer true. Now you can use the collected data and
also continue measurement. Both issue 79_ and issue 448_ described this
problem, and have been fixed.

Plugins can now find unexecuted files if they choose, by implementing the
find_executable_files method. Thanks, Emil Madsen.

Minimal IronPython support. You should be able to run IronPython programs
under coverage run, though you will still have to do the reporting phase
with CPython.

Coverage.py has long had a special hack to support CPython's need to measure
the coverage of the standard library tests. This code was not installed by
kitted versions of coverage.py. Now it is.

4.3.3

Python 2.6 support was broken due to a testing exception imported for the
benefit of the coverage.py test suite. Properly conditionalizing it fixed
issue 554_ so that Python 2.6 works again.

4.3.2

Using the --skip-covered option on an HTML report with 100% coverage
would cause a "No data to report" error, as reported in issue 549_. This is
now fixed; thanks, LoÃ¯c Dachary.

If-statements can be optimized away during compilation, for example, if 0:
or if __debug__:. Coverage.py had problems properly understanding these
statements which existed in the source, but not in the compiled bytecode.
This problem, reported in issue 522_, is now fixed.

If you specified --source as a directory, then coverage.py would look for
importable Python files in that directory, and could identify ones that had
never been executed at all. But if you specified it as a package name, that
detection wasn't performed. Now it is, closing issue 426_. Thanks to LoÃ¯c
Dachary for the fix.

If you started and stopped coverage measurement thousands of times in your
process, you could crash Python with a "Fatal Python error: deallocating
None" error. This is now fixed. Thanks to Alex Groce for the bug report.

On PyPy, measuring coverage in subprocesses could produce a warning: "Trace
function changed, measurement is likely wrong: None". This was spurious, and
has been suppressed.

Previously, coverage.py couldn't start on Jython, due to that implementation
missing the multiprocessing module (issue 551). This problem has now been
fixed. Also, issue 322 about not being able to invoke coverage
conveniently, seems much better: jython -m coverage run myprog.py works
properly.

Let's say you ran the HTML report over and over again in the same output
directory, with --skip-covered. And imagine due to your heroic
test-writing efforts, a file just acheived the goal of 100% coverage. With
coverage.py 4.3, the old HTML file with the less-than-100% coverage would be
left behind. This file is now properly deleted.

4.3.1

Some environments couldn't install 4.3, as described in issue 540_. This is
now fixed.

The check for conflicting --source and --include was too simple in a
few different ways, breaking a few perfectly reasonable use cases, described
in issue 541. The check has been reverted while we re-think the fix for
issue 265.

4.3

Special thanks to LoÃ¯c Dachary, who took an extraordinary interest in
coverage.py and contributed a number of improvements in this release.

Subprocesses that are measured with automatic subprocess measurement_ used
to read in any pre-existing data file. This meant data would be incorrectly
carried forward from run to run. Now those files are not read, so each
subprocess only writes its own data. Fixes issue 510_.

The coverage combine command will now fail if there are no data files to
combine. The combine changes in 4.2 meant that multiple combines could lose
data, leaving you with an empty .coverage data file. Fixes
issue 525, issue 412, issue 516, and probably issue 511.

Coverage.py wouldn't execute sys.excepthook_ when an exception happened in
your program. Now it does, thanks to Andrew Hoos. Closes issue 535_.

Branch coverage fixes:

Branch coverage could misunderstand a finally clause on a try block that
never continued on to the following statement, as described in issue 493_. This is now fixed. Thanks to Joe Doherty for the report and LoÃ¯c
Dachary for the fix.

A while loop with a constant condition (while True) and a continue
statement would be mis-analyzed, as described in issue 496_. This is now
fixed, thanks to a bug report by Eli Skeggs and a fix by LoÃ¯c Dachary.

While loops with constant conditions that were never executed could result
in a non-zero coverage report. Artem Dayneko reported this in issue 502_, and LoÃ¯c Dachary provided the fix.

The HTML report now supports a --skip-covered option like the other
reporting commands. Thanks, LoÃ¯c Dachary for the implementation, closing
issue 433_.

Options can now be read from a tox.ini file, if any. Like setup.cfg, sections
are prefixed with "coverage:", so [run] options will be read from the
[coverage:run] section of tox.ini. Implements part of issue 519_.
Thanks, Stephen Finucane.

Specifying both --source and --include no longer silently ignores the
include setting, instead it fails with a message. Thanks, Nathan Land and
LoÃ¯c Dachary. Closes issue 265_.

The Coverage.combine method has a new parameter, strict=False, to
support failing if there are no data files to combine.

When forking subprocesses, the coverage data files would have the same random
number appended to the file name. This didn't cause problems, because the
file names had the process id also, making collisions (nearly) impossible.
But it was disconcerting. This is now fixed.

The text report now properly sizes headers when skipping some files, fixing
issue 524_. Thanks, Anthony Sottile and LoÃ¯c Dachary.

Coverage.py can now search .pex files for source, just as it can .zip and
.egg. Thanks, Peter Ebden.

Data files are now about 15% smaller.

Improvements in the [run] debug setting:

The "dataio" debug setting now also logs when data files are deleted during
combining or erasing.

A new debug option, "multiproc", for logging the behavior of
concurrency=multiprocessing.

If you used the debug options "config" and "callers" together, you'd get a
call stack printed for every line in the multi-line config output. This is
now fixed.

Fixed an unusual bug involving multiple coding declarations affecting code
containing code in multi-line strings: issue 529_.

Coverage.py will no longer be misled into thinking that a plain file is a
package when interpreting --source options. Thanks, Cosimo Lupo.

If you try to run a non-Python file with coverage.py, you will now get a more
useful error message. Issue 514_.

The default pragma regex changed slightly, but this will only matter to you
if you are deranged and use mixed-case pragmas.

Deal properly with non-ASCII file names in an ASCII-only world, issue 533_.

Programs that set Unicode configuration values could cause UnicodeErrors when
generating HTML reports. Pytest-cov is one example. This is now fixed.

Prevented deprecation warnings from configparser that happened in some
circumstances, closing issue 530_.

Corrected the name of the jquery.ba-throttle-debounce.js library. Thanks,
Ben Finney. Closes issue 505_.

Testing against PyPy 5.6 and PyPy3 5.5.
