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

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.

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_>

Fix: in some cases, even with

, a data filecould 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 filenames 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: 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

_.Fix: the

_.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]

_.Fix: the

report did not properly implement the--fail-under=MIN

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.

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 nolines in them, rather than one phantom line. Fixes

Feature: Now the
--concurrency
setting can have a list of values, so thatthreads and another lightweight threading package can be measured together,
such as
--concurrency=gevent,thread
. Closesissue 1012
_ andissue 1082
_. This also means thatthread
must be explicitly specified in somecases 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 Djangosetting 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 withmultiprocessing wouldn't suppress the data file suffix (
issue 989
_). Thisis now fixed.
Debug: The
coverage debug data
command will now sniff out combinable datafiles, and report on all of them.
Debug: The
coverage debug
command used to accept a number of topics at atime, and show all of them, though this was never documented. This no longer
works, to allow for command-line options in the future.
