This PR updates coverage from 6.3.2 to 7.4.0.

Changelog

7.4.0

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

- In Python 3.12 and above, you can try an experimental core based on the new
:mod:`sys.monitoring <python:sys.monitoring>` module by defining a
``COVERAGE_CORE=sysmon`` environment variable.  This should be faster, though
plugins and dynamic contexts are not yet supported with it.  I am very
interested to hear how it works (or doesn't!) for you.


.. _changes_7-3-4:

7.3.4

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

- Fix: the change for multi-line signature exclusions in 7.3.3 broke other
forms of nested clauses being excluded properly.  This is now fixed, closing
`issue 1713`_.

- Fix: in the HTML report, selecting code for copying won't select the line
numbers also. Thanks, `Robert Harris <pull 1717_>`_.

7.3.3

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

- Fix: function definitions with multi-line signatures can now be excluded by
matching any of the lines, closing `issue 684`_.  Thanks, `Jan Rusak,
Maciej Kowalczyk and Joanna Ejzel <pull 1705_>`_.

- Fix: XML reports could fail with a TypeError if files had numeric components
that were duplicates except for leading zeroes, like ``file1.py`` and
``file001.py``.  Fixes `issue 1709`_.

- The ``coverage annotate`` command used to announce that it would be removed
in a future version. Enough people got in touch to say that they use it, so
it will stay.  Don't expect it to keep up with other new features though.

- Added new :ref:`debug options <cmd_run_debug>`:

- ``pytest`` writes the pytest test name into the debug output.

- ``dataop2`` writes the full data being added to CoverageData objects.

7.3.2

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

- The ``coverage lcov`` command ignored the ``[report] exclude_lines`` and
``[report] exclude_also`` settings (`issue 1684`_).  This is now fixed,
thanks `Jacqueline Lee <pull 1685_>`_.

- Sometimes SQLite will create journal files alongside the coverage.py database
files.  These are ephemeral, but could be mistakenly included when combining
data files.  Now they are always ignored, fixing `issue 1605`_. Thanks to
Brad Smith for suggesting fixes and providing detailed debugging.

- On Python 3.12+, we now disable SQLite writing journal files, which should be
a little faster.

- The new 3.12 soft keyword ``type`` is properly bolded in HTML reports.

- Removed the "fullcoverage" feature used by CPython to measure the coverage of
early-imported standard library modules.  CPython `stopped using it
<88054_>`_ in 2021, and it stopped working completely in Python 3.13.

.. _changes_7-3-1:

7.3.1

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

- The semantics of stars in file patterns has been clarified in the docs.  A
leading or trailing star matches any number of path components, like a double
star would.  This is different than the behavior of a star in the middle of a
pattern.  This discrepancy was `identified by Sviatoslav Sydorenko
<starbad_>`_, who `provided patient detailed diagnosis <pull 1650_>`_ and
graciously agreed to a pragmatic resolution.

- The API docs were missing from the last version. They are now `restored
<apidocs_>`_.

.. _pull 1650: https://github.com/nedbat/coveragepy/pull/1650

.. _changes_7-3-0:

7.3.0

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

- Added a :meth:`.Coverage.collect` context manager to start and stop coverage
data collection.

- Dropped support for Python 3.7.

- Fix: in unusual circumstances, SQLite cannot be set to asynchronous mode.
Coverage.py would fail with the error ``Safety level may not be changed
inside a transaction.`` This is now avoided, closing `issue 1646`_.  Thanks
to Michael Bell for the detailed bug report.

- Docs: examples of configuration files now include separate examples for the
different syntaxes: .coveragerc, pyproject.toml, setup.cfg, and tox.ini.

- Fix: added ``nosemgrep`` comments to our JavaScript code so that
semgrep-based SAST security checks won't raise false alarms about security
problems that aren't problems.

- Added a CITATION.cff file, thanks to `Ken Schackart <pull 1641_>`_.

.. _changes_7-2-7:

7.2.7

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

- Fix: reverted a `change from 6.4.3 <pull 1347b_>`_ that helped Cython, but
also increased the size of data files when using dynamic contexts, as
described in the now-fixed `issue 1586`_. The problem is now avoided due to a
recent change (`issue 1538 <issue 1538b_>`_).  Thanks to `Anders Kaseorg
<pull 1629_>`_ and David Szotten for persisting with problem reports and
detailed diagnoses.

- Wheels are now provided for CPython 3.12.

.. _changes_7-2-6:

7.2.6

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

- Fix: the ``lcov`` command could raise an IndexError exception if a file is
translated to Python but then executed under its own name.  Jinja2 does this
when rendering templates.  Fixes `issue 1553`_.

- Python 3.12 beta 1 now inlines comprehensions.  Previously they were compiled
as invisible functions and coverage.py would warn you if they weren't
completely executed.  This no longer happens under Python 3.12.

- Fix: the ``coverage debug sys`` command includes some environment variables
in its output.  This could have included sensitive data.  Those values are
now hidden with asterisks, closing `issue 1628`_.

.. _changes_7-2-5:

7.2.5

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

- Fix: ``html_report()`` could fail with an AttributeError on ``isatty`` if run
in an unusual environment where sys.stdout had been replaced.  This is now
fixed.


.. _changes_7-2-4:

7.2.4

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

PyCon 2023 sprint fixes!

- Fix: with ``relative_files = true``, specifying a specific file to include or
omit wouldn't work correctly (`issue 1604`_).  This is now fixed, with
testing help by `Marc Gibbons <pull 1608_>`_.

- Fix: the XML report would have an incorrect ``<source>`` element when using
relative files and the source option ended with a slash (`issue 1541`_).
This is now fixed, thanks to `Kevin Brown-Silva <pull 1608_>`_.

- When the HTML report location is printed to the terminal, it's now a
terminal-compatible URL, so that you can click the location to open the HTML
file in your browser.  Finishes `issue 1523`_ thanks to `Ricardo Newbery
<pull 1613_>`_.

- Docs: a new :ref:`Migrating page <migrating>` with details about how to
migrate between major versions of coverage.py.  It currently covers the
wildcard changes in 7.x.  Thanks, `Brian Grohe <pull 1610_>`_.

7.2.3

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

- Fix: the :ref:`config_run_sigterm` setting was meant to capture data if a
process was terminated with a SIGTERM signal, but it didn't always.  This was
fixed thanks to `Lewis Gaul <pull 1600_>`_, closing `issue 1599`_.

- Performance: HTML reports with context information are now much more compact.
File sizes are typically as small as one-third the previous size, but can be
dramatically smaller. This closes `issue 1584`_ thanks to `Oleh Krehel
<pull 1587_>`_.

- Development dependencies no longer use hashed pins, closing `issue 1592`_.

.. _changes_7-2-2:

7.2.2

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

- Fix: if a virtualenv was created inside a source directory, and a sourced
package was installed inside the virtualenv, then all of the third-party
packages inside the virtualenv would be measured.  This was incorrect, but
has now been fixed: only the specified packages will be measured, thanks to
`Manuel Jacob <pull 1560_>`_.

- Fix: the ``coverage lcov`` command could create a .lcov file with incorrect
LF (lines found) and LH (lines hit) totals.  This is now fixed, thanks to
`Ian Moore <pull 1583_>`_.

- Fix: the ``coverage xml`` command on Windows could create a .xml file with
duplicate ``<package>`` elements. This is now fixed, thanks to `Benjamin
Parzella <pull 1574_>`_, closing `issue 1573`_.

7.2.1

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

- Fix: the PyPI page had broken links to documentation pages, but no longer
does, closing `issue 1566`_.

- Fix: public members of the coverage module are now properly indicated so that
mypy will find them, fixing `issue 1564`_.

.. _issue 1566: https://github.com/nedbat/coveragepy/issues/1566


.. _changes_7-2-0:

7.2.0

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

- Added a new setting ``[report] exclude_also`` to let you add more exclusions
without overwriting the defaults.  Thanks, `Alpha Chen <pull 1557_>`_,
closing `issue 1391`_.

- Added a :meth:`.CoverageData.purge_files` method to remove recorded data for
a particular file.  Contributed by `Stephan Deibel <pull 1547_>`_.

- Fix: when reporting commands fail, they will no longer congratulate
themselves with messages like "Wrote XML report to file.xml" before spewing a
traceback about their failure.

- Fix: arguments in the public API that name file paths now accept pathlib.Path
objects.  This includes the ``data_file`` and ``config_file`` arguments to
the Coverage constructor and the ``basename`` argument to CoverageData.
Closes `issue 1552`_.

- Fix: In some embedded environments, an IndexError could occur on stop() when
the originating thread exits before completion.  This is now fixed, thanks to
`Russell Keith-Magee <pull 1543_>`_, closing `issue 1542`_.

- Added a ``py.typed`` file to announce our type-hintedness.  Thanks,
`KotlinIsland <pull 1550_>`_.

7.1.0

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

- Added: the debug output file can now be specified with ``[run] debug_file``
in the configuration file.  Closes `issue 1319`_.

- Performance: fixed a slowdown with dynamic contexts that's been around since
6.4.3.  The fix closes `issue 1538`_.  Thankfully this doesn't break the
`Cython change`_ that fixed `issue 972`_.  Thanks to Mathieu Kniewallner for
the deep investigative work and comprehensive issue report.

- Typing: all product and test code has type annotations.

.. _changes_7-0-5:

7.0.5

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

- Fix: On Python 3.7, a file with type annotations but no ``from __future__
import annotations`` would be missing statements in the coverage report. This
is now fixed, closing `issue 1524`_.

.. _issue 1524: https://github.com/nedbat/coveragepy/issues/1524


.. _changes_7-0-4:

7.0.4

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

- Performance: an internal cache of file names was accidentally disabled,
resulting in sometimes drastic reductions in performance.  This is now fixed,
closing `issue 1527`_.   Thanks to Ivan Ciuvalschii for the reproducible test
case.

.. _issue 1527: https://github.com/nedbat/coveragepy/issues/1527


.. _changes_7-0-3:

7.0.3

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

- Fix: when using pytest-cov or pytest-xdist, or perhaps both, the combining
step could fail with ``assert row is not None`` using 7.0.2.  This was due to
a race condition that has always been possible and is still possible. In
7.0.1 and before, the error was silently swallowed by the combining code.
Now it will produce a message "Couldn't combine data file" and ignore the
data file as it used to do before 7.0.2.  Closes `issue 1522`_.

.. _issue 1522: https://github.com/nedbat/coveragepy/issues/1522


.. _changes_7-0-2:

7.0.2

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

- Fix: when using the ``[run] relative_files = True`` setting, a relative
``[paths]`` pattern was still being made absolute.  This is now fixed,
closing `issue 1519`_.

- Fix: if Python doesn't provide tomllib, then TOML configuration files can
only be read if coverage.py is installed with the ``[toml]`` extra.
Coverage.py will raise an error if TOML support is not installed when it sees
your settings are in a .toml file. But it didn't understand that
``[tools.coverage]`` was a valid section header, so the error wasn't reported
if you used that header, and settings were silently ignored.  This is now
fixed, closing `issue 1516`_.

- Fix: adjusted how decorators are traced on PyPy 7.3.10, fixing `issue 1515`_.

- Fix: the ``coverage lcov`` report did not properly implement the
``--fail-under=MIN`` option.  This has been fixed.

- Refactor: added many type annotations, including a number of refactorings.
This should not affect outward behavior, but they were a bit invasive in some
places, so keep your eyes peeled for oddities.

- Refactor: removed the vestigial and long untested support for Jython and
IronPython.

.. _changes_7-0-1:

7.0.1

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

- When checking if a file mapping resolved to a file that exists, we weren't
considering files in .whl files.  This is now fixed, closing `issue 1511`_.

- File pattern rules were too strict, forbidding plus signs and curly braces in
directory and file names.  This is now fixed, closing `issue 1513`_.

- Unusual Unicode or control characters in source files could prevent
reporting.  This is now fixed, closing `issue 1512`_.

- The PyPy wheel now installs on PyPy 3.7, 3.8, and 3.9, closing `issue 1510`_.

Nothing new beyond 7.0.0b1.


.. _changes_7-0-0b1:

7.0.0b1

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

A number of changes have been made to file path handling, including pattern
matching and path remapping with the ``[paths]`` setting (see
:ref:`config_paths`).  These changes might affect you, and require you to
update your settings.

(This release includes the changes from `6.6.0b1`__, since 6.6.0 was never
released.)

__ https://coverage.readthedocs.io/en/latest/changes.html#changes-6-6-0b1

- Changes to file pattern matching, which might require updating your
configuration:

- Previously, ``*`` would incorrectly match directory separators, making
 precise matching difficult.  This is now fixed, closing `issue 1407`_.

- Now ``**`` matches any number of nested directories, including none.

- Improvements to combining data files when using the
:ref:`config_run_relative_files` setting, which might require updating your
configuration:

- During ``coverage combine``, relative file paths are implicitly combined
 without needing a ``[paths]`` configuration setting.  This also fixed
 `issue 991`_.

- A ``[paths]`` setting like ``*/foo`` will now match ``foo/bar.py`` so that
 relative file paths can be combined more easily.

- The :ref:`config_run_relative_files` setting is properly interpreted in
 more places, fixing `issue 1280`_.

- When remapping file paths with ``[paths]``, a path will be remapped only if
the resulting path exists.  The documentation has long said the prefix had to
exist, but it was never enforced.  This fixes `issue 608`_, improves `issue
649`_, and closes `issue 757`_.

- Reporting operations now implicitly use the ``[paths]`` setting to remap file
paths within a single data file.  Combining multiple files still requires the
``coverage combine`` step, but this simplifies some single-file situations.
Closes `issue 1212`_ and `issue 713`_.

- The ``coverage report`` command now has a ``--format=`` option.  The original
style is now ``--format=text``, and is the default.

- Using ``--format=markdown`` will write the table in Markdown format, thanks
 to `Steve Oswald <pull 1479_>`_, closing `issue 1418`_.

- Using ``--format=total`` will write a single total number to the
 output.  This can be useful for making badges or writing status updates.

- Combining data files with ``coverage combine`` now hashes the data files to
skip files that add no new information.  This can reduce the time needed.
Many details affect the speed-up, but for coverage.py's own test suite,
combining is about 40% faster. Closes `issue 1483`_.

- When searching for completely un-executed files, coverage.py uses the
presence of ``__init__.py`` files to determine which directories have source
that could have been imported.  However, `implicit namespace packages`_ don't
require ``__init__.py``.  A new setting ``[report]
include_namespace_packages`` tells coverage.py to consider these directories
during reporting.  Thanks to `Felix Horvat <pull 1387_>`_ for the
contribution.  Closes `issue 1383`_ and `issue 1024`_.

- Fixed environment variable expansion in pyproject.toml files.  It was overly
broad, causing errors outside of coverage.py settings, as described in `issue
1481`_ and `issue 1345`_.  This is now fixed, but in rare cases will require
changing your pyproject.toml to quote non-string values that use environment
substitution.

- An empty file has a coverage total of 100%, but used to fail with
``--fail-under``.  This has been fixed, closing `issue 1470`_.

- The text report table no longer writes out two separator lines if there are
no files listed in the table.  One is plenty.

- Fixed a mis-measurement of a strange use of wildcard alternatives in
match/case statements, closing `issue 1421`_.

- Fixed internal logic that prevented coverage.py from running on
implementations other than CPython or PyPy (`issue 1474`_).

- The deprecated ``[run] note`` setting has been completely removed.

6.5.0

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

- The JSON report now includes details of which branches were taken, and which
are missing for each file. Thanks, `Christoph Blessing <pull 1438_>`_. Closes
`issue 1425`_.

- Starting with coverage.py 6.2, ``class`` statements were marked as a branch.
This wasn't right, and has been reverted, fixing `issue 1449`_. Note this
will very slightly reduce your coverage total if you are measuring branch
coverage.

- Packaging is now compliant with `PEP 517`_, closing `issue 1395`_.

- A new debug option ``--debug=pathmap`` shows details of the remapping of
paths that happens during combine due to the ``[paths]`` setting.

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

- Wheels are now provided for Python 3.11.


.. _changes_6-4-3:

6.4.3

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

- Fix a failure when combining data files if the file names contained glob-like
patterns.  Thanks, `Michael Krebs and Benjamin Schubert <pull 1405_>`_.

- Fix a messaging failure when combining Windows data files on a different
drive than the current directory, closing `issue 1428`_.  Thanks, `Lorenzo
Micò <pull 1430_>`_.

- Fix path calculations when running in the root directory, as you might do in
a Docker container. Thanks `Arthur Rio <pull 1403_>`_.

- Filtering in the HTML report wouldn't work when reloading the index page.
This is now fixed.  Thanks, `Marc Legendre <pull 1413_>`_.

- Fix a problem with Cython code measurement, closing `issue 972`_.  Thanks,

6.4.2

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

- Updated for a small change in Python 3.11.0 beta 4: modules now start with a
line with line number 0, which is ignored.  This line cannot be executed, so
coverage totals were thrown off.  This line is now ignored by coverage.py,
but this also means that truly empty modules (like ``__init__.py``) have no
lines in them, rather than one phantom line.  Fixes `issue 1419`_.

- Internal debugging data added to sys.modules is now an actual module, to
avoid confusing code that examines everything in sys.modules.  Thanks,
`Yilei Yang <pull 1399_>`_.

.. _changes_6-4-1:

6.4.1

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

- Greatly improved performance on PyPy, and other environments that need the
pure Python trace function.  Thanks, Carl Friedrich Bolz-Tereick (`pull
1381`_ and `pull 1388`_).  Slightly improved performance when using the C
trace function, as most environments do.  Closes `issue 1339`_.

- The conditions for using tomllib from the standard library have been made
more precise, so that 3.11 alphas will continue to work. Closes `issue
1390`_.

6.4

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

- A new setting, :ref:`config_run_sigterm`, controls whether a SIGTERM signal
handler is used.  In 6.3, the signal handler was always installed, to capture
data at unusual process ends.  Unfortunately, this introduced other problems
(see `issue 1310`_).  Now the signal handler is only used if you opt-in by
setting ``[run] sigterm = true``.

- Small changes to the HTML report:

- Added links to next and previous file, and more keyboard shortcuts: ``[``
 and ``]`` for next file and previous file; ``u`` for up to the index; and
 ``?`` to open/close the help panel.  Thanks, `J. M. F. Tsang
 <pull 1364_>`_.

- The time stamp and version are displayed at the top of the report.  Thanks,
 `Ammar Askar <pull 1354_>`_. Closes `issue 1351`_.

- A new debug option ``debug=sqldata`` adds more detail to ``debug=sql``,
logging all the data being written to the database.

- Previously, running ``coverage report`` (or any of the reporting commands) in
an empty directory would create a .coverage data file.  Now they do not,
fixing `issue 1328`_.

- On Python 3.11, the ``[toml]`` extra no longer installs tomli, instead using
tomllib from the standard library.  Thanks `Shantanu <pull 1359_>`_.

- In-memory CoverageData objects now properly update(), closing `issue 1323`_.
