coverage 4.1 -> 4.3.1

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.

.. _issue 540: https://bitbucket.org/ned/coveragepy/issues/540/cant-install-coverage-v43-into-under
.. _issue 541: https://bitbucket.org/ned/coveragepy/issues/541/coverage-43-breaks-nosetest-with-coverage

4.3

---

• 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 issues
  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_.

.. _sys.excepthook: https://docs.python.org/3/library/sys.htmlsys.excepthook

• 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 Loïc
  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 Loïc 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 Loïc Dachary provided the fix.

• The HTML report now supports a --skip-covered option like the other
  reporting commands. Thanks, Loïc 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
  Loïc 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 Loïc 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.

• Switched to pytest from nose for running the coverage.py tests.

• Renamed AUTHORS.txt to CONTRIBUTORS.txt, since there are other ways to
  contribute than by writing code. Also put the count of contributors into the
  author string in setup.py, though this might be too cute.

4.2

---

• Since concurrency=multiprocessing uses subprocesses, options specified on
  the coverage.py command line will not be communicated down to them. Only
  options in the configuration file will apply to the subprocesses.
  Previously, the options didn't apply to the subprocesses, but there was no
  indication. Now it is an error to use --concurrency=multiprocessing and
  other run-affecting options on the command line. This prevents
  failures like those reported in issue 495_.

• Filtering the HTML report is now faster, thanks to Ville Skyttä.

.. _issue 495: https://bitbucket.org/ned/coveragepy/issues/495/branch-and-concurrency-are-conflicting

4.2b1

---

Work from the PyCon 2016 Sprints!

• BACKWARD INCOMPATIBILITY: the coverage combine command now ignores an
  existing .coverage data file. It used to include that file in its
  combining. This caused confusing results, and extra tox "clean" steps. If
  you want the old behavior, use the new coverage combine --append option.

• The concurrency option can now take multiple values, to support programs
  using multiprocessing and another library such as eventlet. This is only
  possible in the configuration file, not from the command line. The
  configuration file is the only way for sub-processes to all run with the same
  options. Fixes issue 484_. Thanks to Josh Williams for prototyping.

• Using a concurrency setting of multiprocessing now implies
  --parallel so that the main program is measured similarly to the
  sub-processes.

• When using automatic subprocess measurement, running coverage commands
  would create spurious data files. This is now fixed, thanks to diagnosis and
  testing by Dan Riti. Closes issue 492.

• A new configuration option, report:sort, controls what column of the
  text report is used to sort the rows. Thanks to Dan Wandschneider, this
  closes issue 199_.

• The HTML report has a more-visible indicator for which column is being
  sorted. Closes issue 298_, thanks to Josh Williams.

• If the HTML report cannot find the source for a file, the message now
  suggests using the -i flag to allow the report to continue. Closes
  issue 231_, thanks, Nathan Land.

• When reports are ignoring errors, there's now a warning if a file cannot be
  parsed, rather than being silently ignored. Closes issue 396_. Thanks,
  Matthew Boehm.

• A new option for coverage debug is available: coverage debug config
  shows the current configuration. Closes issue 454_, thanks to Matthew
  Boehm.

• Running coverage as a module (python -m coverage) no longer shows the
  program name as __main__.py. Fixes issue 478_. Thanks, Scott Belden.

• The test_helpers module has been moved into a separate pip-installable
  package: unittest-mixins_.

pip 8.1.2 -> 9.0.1

9.0.1

• Correct the deprecation message when not specifying a --format so that it
  uses the correct setting name (format) rather than the incorrect one
  (list_format) (:issue:4058).

• Fix pip check to check all available distributions and not just the
  local ones (:issue:4083).

• Fix a crash on non ASCII characters from lsb_release (:issue:4062).

• Fix an SyntaxError in an an used module of a vendored dependency
  (:issue:4059).

• Fix UNC paths on Windows (:issue:4064).

9.0.0

• BACKWARD INCOMPATIBLE Remove the attempted autodetection of requirement
  names from URLs, URLs must include a name via egg=.

• DEPRECATION pip install --egg have been deprecated and will be
  removed in the future. This "feature" has a long list of drawbacks which
  break nearly all of pip's other features in subtle and hard-to-diagnose
  ways.

• DEPRECATION --default-vcs option (:issue:4052).

• WARNING pip 9 cache can break forward compatibility with previous pip
  versions if your package repository allows chunked responses (:issue:4078).

• Add a pip check command to check installed packages dependencies
  (:pull:3750).

• Add option allowing user to abort pip operation if file/directory exists

• Add Appveyor CI

• Uninstall existing packages when performing an editable installation of
  the same packages (:issue:1548).

• pip show is less verbose by default. --verbose prints multiline fields.
  (:pull:3858).

• Add optional column formatting to pip list (:issue:3651).

• Add --not-required option to pip list, which lists packages that are
  not dependencies of other packages.

• Fix builds on systems with symlinked /tmp directory for custom
  builds such as numpy (:pull:3701).

• Fix regression in pip freeze: when there is more than one git remote,
  priority is given to the remote named origin (:pull:3708, :issue:3616).

• Fix crash when calling pip freeze with invalid requirement installed
  (:pull:3704, :issue:3681).

• Allow multiple --requirement files in pip freeze (:pull:3703).

• Implementation of pep-503 data-requires-python. When this field is
  present for a release link, pip will ignore the download when
  installing to a Python version that doesn't satisfy the requirement.

• pip wheel now works on editable packages too (it was only working on
  editable dependencies before); this allows running pip wheel on the result
  of pip freeze in presence of editable requirements (:pull:3695,
  :issue:3291).

• Load credentials from .netrc files (:pull:3715, :issue:3569).

• Add --platform, --python-version, --implementation and --abi parameters to
  pip download. These allow utilities and advanced users to gather
  distributions for interpreters other than the one pip is being run on.
