`v7.6.8`

Compare Source

Fix: the LCOV report code assumed that a branch line that took no branches
meant that the entire line was unexecuted. This isn't true in a few cases:
the line might always raise an exception, or might have been optimized away.
Fixes issue 1896_.
Fix: similarly, the HTML report will now explain that a line that jumps to
none of its expected destinations must have always raised an exception.
Previously, it would say something nonsensical like, "line 4 didn't jump to
line 5 because line 4 was never true, and it didn't jump to line 7 because
line 4 was always true." This was also shown in issue 1896_.

fix: ugh, the other assert from 7.6.5 can also be encountered in the wild,
so it's been restored to a conditional. Sorry for the churn.

One of the new asserts from 7.6.5 caused problems in real projects, as
reported in issue 1891_. The assert has been removed.

fix: fine-tuned the exact Python version (3.12.6) when exiting from with
statements changed how they traced. This affected whether people saw the
fix for issue 1880_.
fix: isolate our code more from mocking in the os module that in rare cases
can cause bizarre behavior <pytest-cov-666_>_.
refactor: some code unreachable code paths in parser.py were changed to
asserts. If you encounter any of these, please let me know!

Fix: nested context managers could incorrectly be analyzed to flag a missing
branch on the last context manager, as described in issue 1876_. This is
now fixed.
Fix: the missing branch message about not exiting a module had an extra
"didn't," as described in issue 1873_. This is now fixed.

`v7.6.2`

Dropped support for Python 3.8 and PyPy 3.8.
Fix: a final wildcard match/case clause assigning to a name (case _ as value) was incorrectly marked as a missing branch. This is now fixed,
closing issue 1860_.
Fewer things are considered branches now. Lambdas, comprehensions, and
generator expressions are no longer marked as missing branches if they don't
complete execution. Closes issue 1852_.
Fix: the HTML report didn't properly show multi-line f-strings that end with
a backslash continuation. This is now fixed, closing issue 1836, thanks
to LiuYinCarl and Marco Ricci <pull 1838_>.
Fix: the LCOV report now has correct line numbers (fixing issue 1846) and
better branch descriptions for BRDA records (fixing issue 1850). There
are other changes to lcov also, including a new configuration option
:ref:line_checksums <config_lcov_line_checksums> to control whether line
checksums are included in the lcov report. The default is false. To keep
checksums set it to true. All this work is thanks to Zack Weinberg
(pull 1849_ and pull 1851_).
Fixed the docs for multi-line regex exclusions, closing issue 1863_.
Fixed a potential crash in the C tracer, closing issue 1835, thanks to
Jan Kühle <pull 1843_>.

Exclusion patterns can now be multi-line, thanks to Daniel Diniz <pull 1807_>. This enables many interesting exclusion use-cases, including those
requested in issues 118 <issue 118_> (entire files), 996 <issue 996_>_ (multiple lines only when appearing together), 1741 <issue 1741_>_ (remainder of a function), and 1803 <issue 1803_>_
(arbitrary sequence of marked lines). See the :ref:multi_line_exclude
section of the docs for more details and examples.
The JSON report now includes per-function and per-class coverage information.
Thanks to Daniel Diniz <pull 1809_>_ for getting the work started. This
closes issue 1793_ and issue 1532_.
Fixed an incorrect calculation of "(no class)" lines in the HTML classes
report.
Python 3.13.0b3 is supported.

`v7.5.4`

If you attempt to combine statement coverage data with branch coverage data,
coverage.py used to fail with the message "Can't combine arc data with line
data" or its reverse, "Can't combine line data with arc data." These
messages used internal terminology, making it hard for people to understand
the problem. They are now changed to mention "branch coverage data" and
"statement coverage data."
Fixed a minor branch coverage problem with wildcard match/case cases using
names or guard clauses.
Started testing on 3.13 free-threading (nogil) builds of Python. I'm not
claiming full support yet. Closes issue 1799_.

Performance improvements for combining data files, especially when measuring
line coverage. A few different quadratic behaviors were eliminated. In one
extreme case of combining 700+ data files, the time dropped from more than
three hours to seven minutes. Thanks for Kraken Tech for funding the fix.
Performance improvements for generating HTML reports, with a side benefit of
reducing memory use, closing issue 1791_. Thanks to Daniel Diniz for
helping to diagnose the problem.

`v7.5.2`

Compare Source

Fix: nested matches of exclude patterns could exclude too much code, as
reported in issue 1779_. This is now fixed.
Changed: previously, coverage.py would consider a module docstring to be an
executable statement if it appeared after line 1 in the file, but not
executable if it was the first line. Now module docstrings are never counted
as executable statements. This can change coverage.py's count of the number
of statements in a file, which can slightly change the coverage percentage
reported.
In the HTML report, the filter term and "hide covered" checkbox settings are
remembered between viewings, thanks to Daniel Diniz <pull 1776_>_.
Python 3.13.0b1 is supported.
Fix: parsing error handling is improved to ensure bizarre source files are
handled gracefully, and to unblock oss-fuzz fuzzing, thanks to Liam DeVoe <pull 1788_>. Closes issue 1787.

Fix: a pragma comment on the continuation lines of a multi-line statement
now excludes the statement and its body, the same as if the pragma is
on the first line. This closes issue 754. The fix was contributed by
Daniel Diniz <pull 1773_>.
Fix: very complex source files like this one <resolvent_lookup_>_ could
cause a maximum recursion error when creating an HTML report. This is now
fixed, closing issue 1774_.
HTML report improvements:
- Support files (JavaScript and CSS) referenced by the HTML report now have
  hashes added to their names to ensure updated files are used instead of
  stale cached copies.
- Missing branch coverage explanations that said "the condition was never
  false" now read "the condition was always true" because it's easier to
  understand.
- Column sort order is remembered better as you move between the index pages,
  fixing issue 1766. Thanks, Daniel Diniz <pull 1768_>.

Added initial support for function and class reporting in the HTML report.
There are now three index pages which link to each other: files, functions,
and classes. Other reports don't yet have this information, but it will be
added in the future where it makes sense. Feedback gladly accepted!
Finishes issue 780_.
Other HTML report improvements:
- There is now a "hide covered" checkbox to filter out 100% files, finishing
  issue 1384_.
- The index page is always sorted by one of its columns, with clearer
  indications of the sorting.
- The "previous file" shortcut key didn't work on the index page, but now it
  does, fixing issue 1765_.
The debug output showing which configuration files were tried now shows
absolute paths to help diagnose problems where settings aren't taking effect,
and is renamed from "attempted_config_files" to the more logical
"config_files_attempted."
Python 3.13.0a6 is supported.

`v7.4.4`

Compare Source

Fix: in some cases, even with [run] relative_files=True, a data file
could be created with absolute path names. When combined with other relative
data files, it was random whether the absolute file names would be made
relative or not. If they weren't, then a file would be listed twice in
reports, as detailed in issue 1752_. This is now fixed: absolute file
names are always made relative when combining. Thanks to Bruno Rodrigues dos
Santos for support.
Fix: the last case of a match/case statement had an incorrect message if the
branch was missed. It said the pattern never matched, when actually the
branch is missed if the last case always matched.
Fix: clicking a line number in the HTML report now positions more accurately.
Fix: the report:format setting was defined as a boolean, but should be a
string. Thanks, Tanaydin Sirin <pull 1754_>_. It is also now documented
on the :ref:configuration page <config_report_format>.

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 for
line coverage, but not for branch coverage, and plugins and dynamic contexts
are not yet supported with it. I am very interested to hear how it works (or
doesn't!) for you.

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>:

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.

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_>_.

`v7.1.0`

Compare Source

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.

`v7.0.5`

Compare Source

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_.

`v7.0.4`

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.

`v7.0.3`

Compare Source

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/15222

.. _changes_7-0-2:

`v7.0.2`

Compare Source

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.

`v7.0.1`

Compare Source

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_.

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.
Fix an internal problem with caching of invalid Python parsing. Found by
OSS-Fuzz, fixing their bug 50381_.

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,

`v6.4.2`

Compare Source

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_>_.

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_.

Fix: adapt to pypy3.9's decorator tracing behavior. It now traces function
decorators like CPython 3.8: both the @-line and the def-line are traced.
Fixes issue 1326_.
Debug: added pybehave to the list of :ref:coverage debug <cmd_debug>
and :ref:cmd_run_debug options.
Fix: show an intelligible error message if --concurrency=multiprocessing
is used without a configuration file. Closes issue 1320_.

Fix: deadlocks could occur when terminating processes. Some of these
deadlocks (described in issue 1310_) are now fixed.
Fix: a signal handler was being set from multiple threads, causing an error:
"ValueError: signal only works in main thread". This is now fixed, closing
issue 1312_.
Fix: --precision on the command-line was being ignored while considering
--fail-under. This is now fixed, thanks to
Marcelo Trylesinski <pull 1317_>_.
Fix: releases no longer provide 3.11.0-alpha wheels. Coverage.py uses CPython
internal fields which are moving during the alpha phase. Fixes issue 1316_.

Feature: Now the --concurrency setting can have a list of values, so that
threads and another lightweight threading package can be measured together,
such as --concurrency=gevent,thread. Closes issue 1012_ and issue 1082_. This also means that thread must be explicitly specified in some
cases that used to be implicit such as --concurrency=multiprocessing,
which must be changed to --concurrency=multiprocessing,thread.
Fix: A module specified as the source setting is imported during startup,
before the user program imports it. This could cause problems if the rest of
the program isn't ready yet. For example, issue 1203_ describes a Django
setting that is accessed before settings have been configured. Now the early
import is wrapped in a try/except so errors then don't stop execution.
Fix: A colon in a decorator expression would cause an exclusion to end too
early, preventing the exclusion of the decorated function. This is now fixed.
Fix: The HTML report now will not overwrite a .gitignore file that already
exists in the HTML output directory (follow-on for issue 1244 <issue 1244b_>_).
API: The exceptions raised by Coverage.py have been specialized, to provide
finer-grained catching of exceptions by third-party code.
API: Using suffix=False when constructing a Coverage object with
multiprocessing wouldn't suppress the data file suffix (issue 989_). This
is now fixed.
Debug: The coverage debug data command will now sniff out combinable data
files, and report on all of them.
Debug: The coverage debug command used to accept a number of topics at a
time, and show all of them, though this was never documented. This no longer
works, to allow for command-line options in the future.

Python 3.11 is supported (tested with 3.11.0a2). One still-open issue has to
do with exits through with-statements <issue 1270_>_.
Fix: When remapping file paths through the [paths] setting while
combining, the [run] relative_files setting was ignored, resulting in
absolute paths for remapped file names (issue 1147_). This is now fixed.
Fix: Complex conditionals over excluded lines could have incorrectly reported
a missing branch (issue 1271_). This is now fixed.
Fix: More exceptions are now handled when trying to parse source files for
reporting. Problems that used to terminate coverage.py can now be handled
with [report] ignore_errors. This helps with plugins failing to read
files (django_coverage_plugin issue 78_).
Fix: Removed another vestige of jQuery from the source tarball
(issue 840 <issue 840b_>_).
Fix: Added a default value for a new-to-6.x argument of an internal class.
This unsupported class is being used by coveralls (issue 1273_). Although
I'd rather not "fix" unsupported interfaces, it's actually nicer with a
default value.
