This PR pins coverage to the latest release 5.5.

Changelog ### 5.5 ``` -------------------------- - ``coverage combine`` has a new option, ``--keep`` to keep the original data files after combining them. The default is still to delete the files after they have been combined. This was requested in `issue 1108`_ and implemented in `pull request 1110`_. Thanks, Éric Larivière. - When reporting missing branches in ``coverage report``, branches aren't reported that jump to missing lines. This adds to the long-standing behavior of not reporting branches from missing lines. Now branches are only reported if both the source and destination lines are executed. Closes both `issue 1065`_ and `issue 955`_. - Minor improvements to the HTML report: - The state of the line visibility selector buttons is saved in local storage so you don't have to fiddle with them so often, fixing `issue 1123`_. - It has a little more room for line numbers so that 4-digit numbers work well, fixing `issue 1124`_. - Improved the error message when combining line and branch data, so that users will be more likely to understand what's happening, closing `issue 803`_. .. _issue 803: https://github.com/nedbat/coveragepy/issues/803 .. _issue 955: https://github.com/nedbat/coveragepy/issues/955 .. _issue 1065: https://github.com/nedbat/coveragepy/issues/1065 .. _issue 1108: https://github.com/nedbat/coveragepy/issues/1108 .. _pull request 1110: https://github.com/nedbat/coveragepy/pull/1110 .. _issue 1123: https://github.com/nedbat/coveragepy/issues/1123 .. _issue 1124: https://github.com/nedbat/coveragepy/issues/1124 .. _changes_54: ``` ### 5.4 ``` -------------------------- - The text report produced by ``coverage report`` now always outputs a TOTAL line, even if only one Python file is reported. This makes regex parsing of the output easier. Thanks, Judson Neer. This had been requested a number of times (`issue 1086`_, `issue 922`_, `issue 732`_). - The ``skip_covered`` and ``skip_empty`` settings in the configuration file can now be specified in the ``[html]`` section, so that text reports and HTML reports can use separate settings. The HTML report will still use the ``[report]`` settings if there isn't a value in the ``[html]`` section. Closes `issue 1090`_. - Combining files on Windows across drives now works properly, fixing `issue 577`_. Thanks, `Valentin Lab <pr1080_>`_. - Fix an obscure warning from deep in the _decimal module, as reported in `issue 1084`_. - Update to support Python 3.10 alphas in progress, including `PEP 626: Precise line numbers for debugging and other tools <pep626_>`_. .. _issue 577: https://github.com/nedbat/coveragepy/issues/577 .. _issue 732: https://github.com/nedbat/coveragepy/issues/732 .. _issue 922: https://github.com/nedbat/coveragepy/issues/922 .. _issue 1084: https://github.com/nedbat/coveragepy/issues/1084 .. _issue 1086: https://github.com/nedbat/coveragepy/issues/1086 .. _issue 1090: https://github.com/nedbat/coveragepy/issues/1090 .. _pr1080: https://github.com/nedbat/coveragepy/pull/1080 .. _pep626: https://www.python.org/dev/peps/pep-0626/ .. _changes_531: ``` ### 5.3.1 ``` ---------------------------- - When using ``--source`` on a large source tree, v5.x was slower than previous versions. This performance regression is now fixed, closing `issue 1037`_. - Mysterious SQLite errors can happen on PyPy, as reported in `issue 1010`_. An immediate retry seems to fix the problem, although it is an unsatisfying solution. - The HTML report now saves the sort order in a more widely supported way, fixing `issue 986`_. Thanks, Sebastián Ramírez (`pull request 1066`_). - The HTML report pages now have a :ref:`Sleepy Snake <sleepy>` favicon. - Wheels are now provided for manylinux2010, and for PyPy3 (pp36 and pp37). - Continuous integration has moved from Travis and AppVeyor to GitHub Actions. .. _issue 986: https://github.com/nedbat/coveragepy/issues/986 .. _issue 1037: https://github.com/nedbat/coveragepy/issues/1037 .. _issue 1010: https://github.com/nedbat/coveragepy/issues/1010 .. _pull request 1066: https://github.com/nedbat/coveragepy/pull/1066 .. _changes_53: ``` ### 5.3 ``` -------------------------- - The ``source`` setting has always been interpreted as either a file path or a module, depending on which existed. If both interpretations were valid, it was assumed to be a file path. The new ``source_pkgs`` setting can be used to name a package to disambiguate this case. Thanks, Thomas Grainger. Fixes `issue 268`_. - If a plugin was disabled due to an exception, we used to still try to record its information, causing an exception, as reported in `issue 1011`_. This is now fixed. .. _issue 268: https://github.com/nedbat/coveragepy/issues/268 .. _issue 1011: https://github.com/nedbat/coveragepy/issues/1011 .. _changes_521: ``` ### 5.2.1 ``` ---------------------------- - The dark mode HTML report still used light colors for the context listing, making them unreadable (`issue 1009`_). This is now fixed. - The time stamp on the HTML report now includes the time zone. Thanks, Xie Yanbo (`pull request 960`_). .. _pull request 960: https://github.com/nedbat/coveragepy/pull/960 .. _issue 1009: https://github.com/nedbat/coveragepy/issues/1009 .. _changes_52: ``` ### 5.2 ``` -------------------------- - The HTML report has been redesigned by Vince Salvino. There is now a dark mode, the code text is larger, and system sans serif fonts are used, in addition to other small changes (`issue 858`_ and `pull request 931`_). - The ``coverage report`` and ``coverage html`` commands now accept a ``--precision`` option to control the number of decimal points displayed. Thanks, Teake Nutma (`pull request 982`_). - The ``coverage report`` and ``coverage html`` commands now accept a ``--no-skip-covered`` option to negate ``--skip-covered``. Thanks, Anthony Sottile (`issue 779`_ and `pull request 932`_). - The ``--skip-empty`` option is now available for the XML report, closing `issue 976`_. - The ``coverage report`` command now accepts a ``--sort`` option to specify how to sort the results. Thanks, Jerin Peter George (`pull request 1005`_). - If coverage fails due to the coverage total not reaching the ``--fail-under`` value, it will now print a message making the condition clear. Thanks, Naveen Yadav (`pull request 977`_). - TOML configuration files with non-ASCII characters would cause errors on Windows (`issue 990`_). This is now fixed. - The output of ``--debug=trace`` now includes information about how the ``--source`` option is being interpreted, and the module names being considered. .. _pull request 931: https://github.com/nedbat/coveragepy/pull/931 .. _pull request 932: https://github.com/nedbat/coveragepy/pull/932 .. _pull request 977: https://github.com/nedbat/coveragepy/pull/977 .. _pull request 982: https://github.com/nedbat/coveragepy/pull/982 .. _pull request 1005: https://github.com/nedbat/coveragepy/pull/1005 .. _issue 779: https://github.com/nedbat/coveragepy/issues/779 .. _issue 858: https://github.com/nedbat/coveragepy/issues/858 .. _issue 976: https://github.com/nedbat/coveragepy/issues/976 .. _issue 990: https://github.com/nedbat/coveragepy/issues/990 .. _changes_51: ``` ### 5.1 ``` -------------------------- - The JSON report now includes counts of covered and missing branches. Thanks, Salvatore Zagaria. - On Python 3.8, try-finally-return reported wrong branch coverage with decorated async functions (`issue 964`_). This is now fixed. Thanks, Kjell Braden. - The :meth:`~coverage.Coverage.get_option` and :meth:`~coverage.Coverage.set_option` methods can now manipulate the ``[paths]`` configuration setting. Thanks to Bernát Gábor for the fix for `issue 967`_. .. _issue 964: https://github.com/nedbat/coveragepy/issues/964 .. _issue 967: https://github.com/nedbat/coveragepy/issues/967 .. _changes_504: ``` ### 5.0.4 ``` ---------------------------- - If using the ``[run] relative_files`` setting, the XML report will use relative files in the ``<source>`` elements indicating the location of source code. Closes `issue 948`_. - The textual summary report could report missing lines with negative line numbers on PyPy3 7.1 (`issue 943`_). This is now fixed. - Windows wheels for Python 3.8 were incorrectly built, but are now fixed. (`issue 949`_) - Updated Python 3.9 support to 3.9a4. - HTML reports couldn't be sorted if localStorage wasn't available. This is now fixed: sorting works even though the sorting setting isn't retained. (`issue 944`_ and `pull request 945`_). Thanks, Abdeali Kothari. .. _issue 943: https://github.com/nedbat/coveragepy/issues/943 .. _issue 944: https://github.com/nedbat/coveragepy/issues/944 .. _pull request 945: https://github.com/nedbat/coveragepy/pull/945 .. _issue 948: https://github.com/nedbat/coveragepy/issues/948 .. _issue 949: https://github.com/nedbat/coveragepy/issues/949 .. _changes_503: ``` ### 5.0.3 ``` ---------------------------- - A performance improvement in 5.0.2 didn't work for test suites that changed directory before combining data, causing "Couldn't use data file: no such table: meta" errors (`issue 916`_). This is now fixed. - Coverage could fail to run your program with some form of "ModuleNotFound" or "ImportError" trying to import from the current directory. This would happen if coverage had been packaged into a zip file (for example, on Windows), or was found indirectly (for example, by pyenv-virtualenv). A number of different scenarios were described in `issue 862`_ which is now fixed. Huge thanks to Agbonze O. Jeremiah for reporting it, and Alexander Waters and George-Cristian Bîrzan for protracted debugging sessions. - Added the "premain" debug option. - Added SQLite compile-time options to the "debug sys" output. .. _issue 862: https://github.com/nedbat/coveragepy/issues/862 .. _issue 916: https://github.com/nedbat/coveragepy/issues/916 .. _changes_502: ``` ### 5.0.2 ``` ---------------------------- - Programs that used multiprocessing and changed directories would fail under coverage. This is now fixed (`issue 890`_). A side effect is that debug information about the config files read now shows absolute paths to the files. - When running programs as modules (``coverage run -m``) with ``--source``, some measured modules were imported before coverage starts. This resulted in unwanted warnings ("Already imported a file that will be measured") and a reduction in coverage totals (`issue 909`_). This is now fixed. - If no data was collected, an exception about "No data to report" could happen instead of a 0% report being created (`issue 884`_). This is now fixed. - The handling of source files with non-encodable file names has changed. Previously, if a file name could not be encoded as UTF-8, an error occurred, as described in `issue 891`_. Now, those files will not be measured, since their data would not be recordable. - A new warning ("dynamic-conflict") is issued if two mechanisms are trying to change the dynamic context. Closes `issue 901`_. - ``coverage run --debug=sys`` would fail with an AttributeError. This is now fixed (`issue 907`_). .. _issue 884: https://github.com/nedbat/coveragepy/issues/884 .. _issue 890: https://github.com/nedbat/coveragepy/issues/890 .. _issue 891: https://github.com/nedbat/coveragepy/issues/891 .. _issue 901: https://github.com/nedbat/coveragepy/issues/901 .. _issue 907: https://github.com/nedbat/coveragepy/issues/907 .. _issue 909: https://github.com/nedbat/coveragepy/issues/909 .. _changes_501: ``` ### 5.0.1 ``` ---------------------------- - If a 4.x data file is the cause of a "file is not a database" error, then use a more specific error message, "Looks like a coverage 4.x data file, are you mixing versions of coverage?" Helps diagnose the problems described in `issue 886`_. - Measurement contexts and relative file names didn't work together, as reported in `issue 899`_ and `issue 900`_. This is now fixed, thanks to David Szotten. - When using ``coverage run --concurrency=multiprocessing``, all data files should be named with parallel-ready suffixes. 5.0 mistakenly named the main process' file with no suffix when using ``--append``. This is now fixed, closing `issue 880`_. - Fixed a problem on Windows when the current directory is changed to a different drive (`issue 895`_). Thanks, Olivier Grisel. - Updated Python 3.9 support to 3.9a2. .. _issue 880: https://github.com/nedbat/coveragepy/issues/880 .. _issue 886: https://github.com/nedbat/coveragepy/issues/886 .. _issue 895: https://github.com/nedbat/coveragepy/issues/895 .. _issue 899: https://github.com/nedbat/coveragepy/issues/899 .. _issue 900: https://github.com/nedbat/coveragepy/issues/900 .. _changes_50: ``` ### 5.0 ``` -------------------------- Nothing new beyond 5.0b2. .. _changes_50b2: ``` ### 5.0b2 ``` ---------------------------- - An experimental ``[run] relative_files`` setting tells coverage to store relative file names in the data file. This makes it easier to run tests in one (or many) environments, and then report in another. It has not had much real-world testing, so it may change in incompatible ways in the future. - When constructing a :class:`coverage.Coverage` object, `data_file` can be specified as None to prevent writing any data file at all. In previous versions, an explicit `data_file=None` argument would use the default of ".coverage". Fixes `issue 871`_. - Python files run with ``-m`` now have ``__spec__`` defined properly. This fixes `issue 745`_ (about not being able to run unittest tests that spawn subprocesses), and `issue 838`_, which described the problem directly. - The ``[paths]`` configuration section is now ordered. If you specify more than one list of patterns, the first one that matches will be used. Fixes `issue 649`_. - The :func:`.coverage.numbits.register_sqlite_functions` function now also registers `numbits_to_nums` for use in SQLite queries. Thanks, Simon Willison. - Python 3.9a1 is supported. - Coverage.py has a mascot: :ref:`Sleepy Snake <sleepy>`. .. _issue 649: https://github.com/nedbat/coveragepy/issues/649 .. _issue 745: https://github.com/nedbat/coveragepy/issues/745 .. _issue 838: https://github.com/nedbat/coveragepy/issues/838 .. _issue 871: https://github.com/nedbat/coveragepy/issues/871 .. _changes_50b1: ``` ### 5.0b1 ``` ---------------------------- - The HTML and textual reports now have a ``--skip-empty`` option that skips files with no statements, notably ``__init__.py`` files. Thanks, Reya B. - Configuration can now be read from `TOML`_ files. This requires installing coverage.py with the ``[toml]`` extra. The standard "pyproject.toml" file will be read automatically if no other configuration file is found, with settings in the ``[tool.coverage.]`` namespace. Thanks to Frazer McLean for implementation and persistence. Finishes `issue 664`_. - The ``[run] note`` setting has been deprecated. Using it will result in a warning, and the note will not be written to the data file. The corresponding :class:`.CoverageData` methods have been removed. - The HTML report has been reimplemented (no more table around the source code). This allowed for a better presentation of the context information, hopefully resolving `issue 855`_. - Added sqlite3 module version information to ``coverage debug sys`` output. - Asking the HTML report to show contexts (``[html] show_contexts=True`` or ``coverage html --show-contexts``) will issue a warning if there were no contexts measured (`issue 851`_). .. _TOML: https://toml.io/ .. _issue 664: https://github.com/nedbat/coveragepy/issues/664 .. _issue 851: https://github.com/nedbat/coveragepy/issues/851 .. _issue 855: https://github.com/nedbat/coveragepy/issues/855 .. _changes_50a8: ``` ### 5.0a8 ``` ---------------------------- - The :class:`.CoverageData` API has changed how queries are limited to specific contexts. Now you use :meth:`.CoverageData.set_query_context` to set a single exact-match string, or :meth:`.CoverageData.set_query_contexts` to set a list of regular expressions to match contexts. This changes the command-line ``--contexts`` option to use regular expressions instead of filename-style wildcards. .. _changes_50a7: ``` ### 5.0a7 ``` ---------------------------- - Data can now be "reported" in JSON format, for programmatic use, as requested in `issue 720`_. The new ``coverage json`` command writes raw and summarized data to a JSON file. Thanks, Matt Bachmann. - Dynamic contexts are now supported in the Python tracer, which is important for PyPy users. Closes `issue 846`_. - The compact line number representation introduced in 5.0a6 is called a "numbits." The :mod:`coverage.numbits` module provides functions for working with them. - The reporting methods used to permanently apply their arguments to the configuration of the Coverage object. Now they no longer do. The arguments affect the operation of the method, but do not persist. - A class named "test_something" no longer confuses the ``test_function`` dynamic context setting. Fixes `issue 829`_. - Fixed an unusual tokenizing issue with backslashes in comments. Fixes `issue 822`_. - ``debug=plugin`` didn't properly support configuration or dynamic context plugins, but now it does, closing `issue 834`_. .. _issue 720: https://github.com/nedbat/coveragepy/issues/720 .. _issue 822: https://github.com/nedbat/coveragepy/issues/822 .. _issue 834: https://github.com/nedbat/coveragepy/issues/834 .. _issue 829: https://github.com/nedbat/coveragepy/issues/829 .. _issue 846: https://github.com/nedbat/coveragepy/issues/846 .. _changes_50a6: ``` ### 5.0a6 ``` ---------------------------- - Reporting on contexts. Big thanks to Stephan Richter and Albertas Agejevas for the contribution. - The ``--contexts`` option is available on the ``report`` and ``html`` commands. It's a comma-separated list of shell-style wildcards, selecting the contexts to report on. Only contexts matching one of the wildcards will be included in the report. - The ``--show-contexts`` option for the ``html`` command adds context information to each covered line. Hovering over the "ctx" marker at the end of the line reveals a list of the contexts that covered the line. - Database changes: - Line numbers are now stored in a much more compact way. For each file and context, a single binary string is stored with a bit per line number. This greatly improves memory use, but makes ad-hoc use difficult. - Dynamic contexts with no data are no longer written to the database. - SQLite data storage is now faster. There's no longer a reason to keep the JSON data file code, so it has been removed. - Changes to the :class:`.CoverageData` interface: - The new :meth:`.CoverageData.dumps` method serializes the data to a string, and a corresponding :meth:`.CoverageData.loads` method reconstitutes this data. The format of the data string is subject to change at any time, and so should only be used between two installations of the same version of coverage.py. - The :meth:`CoverageData constructor<.CoverageData.__init__>` has a new argument, `no_disk` (default: False). Setting it to True prevents writing any data to the disk. This is useful for transient data objects. - Added the classmethod :meth:`.Coverage.current` to get the latest started Coverage instance. - Multiprocessing support in Python 3.8 was broken, but is now fixed. Closes `issue 828`_. - Error handling during reporting has changed slightly. All reporting methods now behave the same. The ``--ignore-errors`` option keeps errors from stopping the reporting, but files that couldn't parse as Python will always be reported as warnings. As with other warnings, you can suppress them with the ``[run] disable_warnings`` configuration setting. - Coverage.py no longer fails if the user program deletes its current directory. Fixes `issue 806`_. Thanks, Dan Hemberger. - The scrollbar markers in the HTML report now accurately show the highlighted lines, regardless of what categories of line are highlighted. - The hack to accommodate ShiningPanda_ looking for an obsolete internal data file has been removed, since ShiningPanda 0.22 fixed it four years ago. - The deprecated `Reporter.file_reporters` property has been removed. .. _ShiningPanda: https://wiki.jenkins.io/display/JENKINS/ShiningPanda+Plugin .. _issue 806: https://github.com/nedbat/coveragepy/pull/806 .. _issue 828: https://github.com/nedbat/coveragepy/issues/828 .. _changes_50a5: ``` ### 5.0a5 ``` ---------------------------- - Drop support for Python 3.4 - Dynamic contexts can now be set two new ways, both thanks to Justas Sadzevičius. - A plugin can implement a ``dynamic_context`` method to check frames for whether a new context should be started. See :ref:`dynamic_context_plugins` for more details. - Another tool (such as a test runner) can use the new :meth:`.Coverage.switch_context` method to explicitly change the context. - The ``dynamic_context = test_function`` setting now works with Python 2 old-style classes, though it only reports the method name, not the class it was defined on. Closes `issue 797`_. - ``fail_under`` values more than 100 are reported as errors. Thanks to Mike Fiedler for closing `issue 746`_. - The "missing" values in the text output are now sorted by line number, so that missing branches are reported near the other lines they affect. The values used to show all missing lines, and then all missing branches. - Access to the SQLite database used for data storage is now thread-safe. Thanks, Stephan Richter. This closes `issue 702`_. - Combining data stored in SQLite is now about twice as fast, fixing `issue 761`_. Thanks, Stephan Richter. - The ``filename`` attribute on :class:`.CoverageData` objects has been made private. You can use the ``data_filename`` method to get the actual file name being used to store data, and the ``base_filename`` method to get the original filename before parallelizing suffixes were added. This is part of fixing `issue 708`_. - Line numbers in the HTML report now align properly with source lines, even when Chrome's minimum font size is set, fixing `issue 748`_. Thanks Wen Ye. .. _issue 702: https://github.com/nedbat/coveragepy/issues/702 .. _issue 708: https://github.com/nedbat/coveragepy/issues/708 .. _issue 746: https://github.com/nedbat/coveragepy/issues/746 .. _issue 748: https://github.com/nedbat/coveragepy/issues/748 .. _issue 761: https://github.com/nedbat/coveragepy/issues/761 .. _issue 797: https://github.com/nedbat/coveragepy/issues/797 .. _changes_50a4: ``` ### 5.0a4 ``` ---------------------------- - You can specify the command line to run your program with the ``[run] command_line`` configuration setting, as requested in `issue 695`_. - Coverage will create directories as needed for the data file if they don't exist, closing `issue 721`_. - The ``coverage run`` command has always adjusted the first entry in sys.path, to properly emulate how Python runs your program. Now this adjustment is skipped if sys.path[0] is already different than Python's default. This fixes `issue 715`_. - Improvements to context support: - The "no such table: meta" error is fixed.: `issue 716`_. - Combining data files is now much faster. - Python 3.8 (as of today!) passes all tests. .. _issue 695: https://github.com/nedbat/coveragepy/issues/695 .. _issue 715: https://github.com/nedbat/coveragepy/issues/715 .. _issue 716: https://github.com/nedbat/coveragepy/issues/716 .. _issue 721: https://github.com/nedbat/coveragepy/issues/721 .. _changes_50a3: ``` ### 5.0a3 ``` ---------------------------- - Context support: static contexts let you specify a label for a coverage run, which is recorded in the data, and retained when you combine files. See :ref:`contexts` for more information. - Dynamic contexts: specifying ``[run] dynamic_context = test_function`` in the config file will record the test function name as a dynamic context during execution. This is the core of "Who Tests What" (`issue 170`_). Things to note: - There is no reporting support yet. Use SQLite to query the .coverage file for information. Ideas are welcome about how reporting could be extended to use this data. - There's a noticeable slow-down before any test is run. - Data files will now be roughly N times larger, where N is the number of tests you have. Combining data files is therefore also N times slower. - No other values for ``dynamic_context`` are recognized yet. Let me know what else would be useful. I'd like to use a pytest plugin to get better information directly from pytest, for example. .. _issue 170: https://github.com/nedbat/coveragepy/issues/170 - Environment variable substitution in configuration files now supports two syntaxes for controlling the behavior of undefined variables: if ``VARNAME`` is not defined, ``${VARNAME?}`` will raise an error, and ``${VARNAME-default value}`` will use "default value". - Partial support for Python 3.8, which has not yet released an alpha. Fixes `issue 707`_ and `issue 714`_. .. _issue 707: https://github.com/nedbat/coveragepy/issues/707 .. _issue 714: https://github.com/nedbat/coveragepy/issues/714 .. _changes_50a2: ``` ### 5.0a2 ``` ---------------------------- - Coverage's data storage has changed. In version 4.x, .coverage files were basically JSON. Now, they are SQLite databases. This means the data file can be created earlier than it used to. A large amount of code was refactored to support this change. - Because the data file is created differently than previous releases, you may need ``parallel=true`` where you didn't before. - The old data format is still available (for now) by setting the environment variable COVERAGE_STORAGE=json. Please tell me if you think you need to keep the JSON format. - The database schema is guaranteed to change in the future, to support new features. I'm looking for opinions about making the schema part of the public API to coverage.py or not. - Development moved from `Bitbucket`_ to `GitHub`_. - HTML files no longer have trailing and extra whitespace. - The sort order in the HTML report is stored in local storage rather than cookies, closing `issue 611`_. Thanks, Federico Bond. - pickle2json, for converting v3 data files to v4 data files, has been removed. .. _Bitbucket: https://bitbucket.org .. _GitHub: https://github.com/nedbat/coveragepy .. _issue 611: https://github.com/nedbat/coveragepy/issues/611 .. _changes_50a1: ``` ### 5.0a1 ``` ---------------------------- - Coverage.py no longer supports Python 2.6 or 3.3. - The location of the configuration file can now be specified with a ``COVERAGE_RCFILE`` environment variable, as requested in `issue 650`_. - Namespace packages are supported on Python 3.7, where they used to cause TypeErrors about path being None. Fixes `issue 700`_. - A new warning (``already-imported``) is issued if measurable files have already been imported before coverage.py started measurement. See :ref:`cmd_warnings` for more information. - Running coverage many times for small runs in a single process should be faster, closing `issue 625`_. Thanks, David MacIver. - Large HTML report pages load faster. Thanks, Pankaj Pandey. .. _issue 625: https://github.com/nedbat/coveragepy/issues/625 .. _issue 650: https://github.com/nedbat/coveragepy/issues/650 .. _issue 700: https://github.com/nedbat/coveragepy/issues/700 .. _changes_454: ``` ### 4.5.4 ``` ---------------------------- - Multiprocessing support in Python 3.8 was broken, but is now fixed.

Fixes `issue 700`_. - Python 3.8 (as of today!) passes all tests. Fixes `issue 707`_ and `issue 714`_. - Development moved from `Bitbucket`_ to `GitHub`_. .. _issue 700: https://github.com/nedbat/coveragepy/issues/700 .. _issue 707: https://github.com/nedbat/coveragepy/issues/707 .. _issue 714: https://github.com/nedbat/coveragepy/issues/714 .. _Bitbucket: https://bitbucket.org .. _GitHub: https://github.com/nedbat/coveragepy .. _changes_451: ``` ### 4.5.1 ``` ---------------------------- - Now that 4.5 properly separated the ``[run] omit`` and ``[report] omit`` settings, an old bug has become apparent. If you specified a package name for ``[run] source``, then omit patterns weren't matched inside that package. This bug (`issue 638`_) is now fixed. - On Python 3.7, reporting about a decorated function with no body other than a docstring would crash coverage.py with an IndexError (`issue 640`_). This is now fixed. - Configurer plugins are now reported in the output of ``--debug=sys``. .. _issue 638: https://github.com/nedbat/coveragepy/issues/638 .. _issue 640: https://github.com/nedbat/coveragepy/issues/640 .. _changes_45: ``` ### 4.5 ``` -------------------------- - A new kind of plugin is supported: configurers are invoked at start-up to allow more complex configuration than the .coveragerc file can easily do. See :ref:`api_plugin` for details. This solves the complex configuration problem described in `issue 563`_. - The ``fail_under`` option can now be a float. Note that you must specify the ``[report] precision`` configuration option for the fractional part to be used. Thanks to Lars Hupfeldt Nielsen for help with the implementation. Fixes `issue 631`_. - The ``include`` and ``omit`` options can be specified for both the ``[run]`` and ``[report]`` phases of execution. 4.4.2 introduced some incorrect interactions between those phases, where the options for one were confused for the other. This is now corrected, fixing `issue 621`_ and `issue 622`_. Thanks to Daniel Hahler for seeing more clearly than I could. - The ``coverage combine`` command used to always overwrite the data file, even when no data had been read from apparently combinable files. Now, an error is raised if we thought there were files to combine, but in fact none of them could be used. Fixes `issue 629`_. - The ``coverage combine`` command could get confused about path separators when combining data collected on Windows with data collected on Linux, as described in `issue 618`_. This is now fixed: the result path always uses the path separator specified in the ``[paths]`` result. - On Windows, the HTML report could fail when source trees are deeply nested, due to attempting to create HTML filenames longer than the 250-character maximum. Now filenames will never get much larger than 200 characters, fixing `issue 627`_. Thanks to Alex Sandro for helping with the fix. .. _issue 563: https://github.com/nedbat/coveragepy/issues/563 .. _issue 618: https://github.com/nedbat/coveragepy/issues/618 .. _issue 621: https://github.com/nedbat/coveragepy/issues/621 .. _issue 622: https://github.com/nedbat/coveragepy/issues/622 .. _issue 627: https://github.com/nedbat/coveragepy/issues/627 .. _issue 629: https://github.com/nedbat/coveragepy/issues/629 .. _issue 631: https://github.com/nedbat/coveragepy/issues/631 .. _changes_442: ``` ### 4.4.2 ``` ---------------------------- - Support for Python 3.7. In some cases, class and module docstrings are no longer counted in statement totals, which could slightly change your total results. - Specifying both ``--source`` and ``--include`` no longer silently ignores the include setting, instead it displays a warning. Thanks, Loïc Dachary. Closes `issue 265`_ and `issue 101`_. - Fixed a race condition when saving data and multiple threads are tracing (`issue 581`_). It could produce a "dictionary changed size during iteration" RuntimeError. I believe this mostly but not entirely fixes the race condition. A true fix would likely be too expensive. Thanks, Peter Baughman for the debugging, and Olivier Grisel for the fix with tests. - Configuration values which are file paths will now apply tilde-expansion, closing `issue 589`_. - Now secondary config files like tox.ini and setup.cfg can be specified explicitly, and prefixed sections like `[coverage:run]` will be read. Fixes `issue 588`_. - Be more flexible about the command name displayed by help, fixing `issue 600`_. Thanks, Ben Finney. .. _issue 101: https://github.com/nedbat/coveragepy/issues/101 .. _issue 581: https://github.com/nedbat/coveragepy/issues/581 .. _issue 588: https://github.com/nedbat/coveragepy/issues/588 .. _issue 589: https://github.com/nedbat/coveragepy/issues/589 .. _issue 600: https://github.com/nedbat/coveragepy/issues/600 .. _changes_441: ``` ### 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`_) .. _issue 526: https://github.com/nedbat/coveragepy/issues/526 .. _issue 572: https://github.com/nedbat/coveragepy/issues/572 .. _issue 573: https://github.com/nedbat/coveragepy/issues/573 .. _issue 575: https://github.com/nedbat/coveragepy/issues/575 ``` ### 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. .. _issue 79: https://github.com/nedbat/coveragepy/issues/79 .. _issue 96: https://github.com/nedbat/coveragepy/issues/96 .. _issue 355: https://github.com/nedbat/coveragepy/issues/355 .. _issue 448: https://github.com/nedbat/coveragepy/issues/448 .. _issue 570: https://github.com/nedbat/coveragepy/issues/570 .. _changes_434: ``` ### 4.3.4 ``` ---------------------------- - Fixing 2.6 in version 4.3.3 broke other things, because the too-tricky exception wasn't properly derived from Exception, described in `issue 556`_. A newb mistake; it hasn't been a good few days. .. _issue 556: https://github.com/nedbat/coveragepy/issues/556 .. _changes_433: ``` ### 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. .. _issue 554: https://github.com/nedbat/coveragepy/issues/554 .. _changes_432: ``` ### 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, Loïc 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 Loïc 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 achieved 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. .. _issue 322: https://github.com/nedbat/coveragepy/issues/322 .. _issue 426: https://github.com/nedbat/coveragepy/issues/426 .. _issue 522: https://github.com/nedbat/coveragepy/issues/522 .. _issue 549: https://github.com/nedbat/coveragepy/issues/549 .. _issue 551: https://github.com/nedbat/coveragepy/issues/551 .. _changes_431: ``` ### 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://github.com/nedbat/coveragepy/issues/540 .. _issue 541: https://github.com/nedbat/coveragepy/issues/541 .. _changes_43: ``` ### 4.3 ``` -------------------------- Special thanks to **Loïc 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 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. .. _sys.excepthook: https://docs.python.org/3/library/sys.html#sys.excepthook .. _issue 265: https://github.com/nedbat/coveragepy/issues/265 .. _issue 412: https://github.com/nedbat/coveragepy/issues/412 .. _issue 433: https://github.com/nedbat/coveragepy/issues/433 .. _issue 493: https://github.com/nedbat/coveragepy/issues/493 .. _issue 496: https://github.com/nedbat/coveragepy/issues/496 .. _issue 502: https://github.com/nedbat/coveragepy/issues/502 .. _issue 505: https://github.com/nedbat/coveragepy/issues/505 .. _issue 514: https://github.com/nedbat/coveragepy/issues/514 .. _issue 510: https://github.com/nedbat/coveragepy/issues/510 .. _issue 511: https://github.com/nedbat/coveragepy/issues/511 .. _issue 516: https://github.com/nedbat/coveragepy/issues/516 .. _issue 519: https://github.com/nedbat/coveragepy/issues/519 .. _issue 524: https://github.com/nedbat/coveragepy/issues/524 .. _issue 525: https://github.com/nedbat/coveragepy/issues/525 .. _issue 529: https://github.com/nedbat/coveragepy/issues/529 .. _issue 530: https://github.com/nedbat/coveragepy/issues/530 .. _issue 533: https://github.com/nedbat/coveragepy/issues/533 .. _issue 535: https://github.com/nedbat/coveragepy/issues/535 .. _changes_42: ``` ### 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://github.com/nedbat/coveragepy/issues/495 ``` ### 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`_. .. _automatic subprocess measurement: https://coverage.readthedocs.io/en/latest/subprocess.html .. _issue 199: https://github.com/nedbat/coveragepy/issues/199 .. _issue 231: https://github.com/nedbat/coveragepy/issues/231 .. _issue 298: https://github.com/nedbat/coveragepy/issues/298 .. _issue 396: https://github.com/nedbat/coveragepy/issues/396 .. _issue 454: https://github.com/nedbat/coveragepy/issues/454 .. _issue 478: https://github.com/nedbat/coveragepy/issues/478 .. _issue 484: https://github.com/nedbat/coveragepy/issues/484 .. _issue 492: https://github.com/nedbat/coveragepy/issues/492 .. _unittest-mixins: https://pypi.org/project/unittest-mixins/ .. _changes_41: ``` ### 4.1 ``` -------------------------- - The internal attribute `Reporter.file_reporters` was removed in 4.1b3. It should have come has no surprise that there were third-party tools out there using that attribute. It has been restored, but with a deprecation warning. ``` ### 4.1b3 ``` ---------------------------- - When running your program, execution can jump from an ``except X:`` line to some other line when an exception other than ``X`` happens. This jump is no longer considered a branch when measuring branch coverage. - When measuring branch coverage, ``yield`` statements that were never resumed were incorrectly marked as missing, as reported in `issue 440`_. This is now fixed. - During branch coverage of single-line callables like lambdas and generator expressions, coverage.py can now distinguish between them never being called, or being called but not completed. Fixes `issue 90`_, `issue 460`_ and `issue 475`_. - The HTML report now has a map of the file along the rightmost edge of the page, giving an overview of where the missed lines are. Thanks, Dmitry Shishov. - The HTML report now uses different monospaced fonts, favoring Consolas over Courier. Along the way, `issue 472`_ about not properly handling one-space indents was fixed. The index page also has slightly different styling, to try to make the clickable detail pages more apparent. - Missing branches reported with ``coverage report -m`` will now say ``->exit`` for missed branches to the exit of a function, rather than a negative number. Fixes `issue 469`_. - ``coverage --help`` and ``coverage --version`` now mention which tracer is installed, to help diagnose problems. The docs mention which features need the C extension. (`issue 479`_) - Officially support PyPy 5.1, which required no changes, just updates to the docs. - The `Coverage.report` function had two parameters with non-None defaults, which have been changed. `show_missing` used to default to True, but now defaults to None. If you had been calling `Coverage.report` without specifying `show_missing`, you'll need to explicitly set it to True to keep the same behavior. `skip_covered` used to default to False. It is now None, which doesn't change the behavior. This fixes `issue 485`_. - It's never been possible to pass a namespace module to one of the analysis functions, but now at least we raise a more specific error message, rather than getting confused. (`issue 456`_) - The `coverage.process_startup` function now returns the `Coverage` instance it creates, as suggested in `issue 481`_. - Make a small tweak to how we compare threads, to avoid buggy custom comparison code in thread classes.

Now they no longer are. - ``yield from`` and ``await`` were considered returns from functions, since they could transfer control to the caller. This produced unhelpful "missing branch" reports in a number of circumstances. Now they no longer are considered returns. - In unusual situations, a missing branch to a negative number was reported. This has been fixed, closing `issue 466`_. - The XML report now produces correct package names for modules found in directories specified with ``source=``. Fixes `issue 465`_. - ``coverage report`` won't produce trailing whitespace. .. _issue 465: https://github.com/nedbat/coveragepy/issues/465 .. _issue 466: https://github.com/nedbat/coveragepy/issues/466 ``` ### 4.1b1 ``` ---------------------------- - Branch analysis has been rewritten: it used to be based on bytecode, but now uses AST analysis. This has changed a number of things: - More code paths are now considered runnable, especially in ``try``/``except`` structures. This may mean that coverage.py will identify more code paths as uncovered. This could either raise or lower your overall coverage number. - Python 3.5's ``async`` and ``await`` keywords are properly supported, fixing `issue 434`_. - Some long-standing branch coverage bugs were fixed: - `issue 129`_: functions with only a docstring for a body would incorrectly report a missing branch on the ``def`` line. - `issue 212`_: code in an ``except`` block could be incorrectly marked as a missing branch. - `issue 146`_: context managers (``with`` statements) in a loop or ``try`` block could confuse the branch measurement, reporting incorrect partial branches. - `issue 422`_: in Python 3.5, an actual partial branch could be marked as complete. - Pragmas to disable coverage measurement can now be used on decorator lines, and they will apply to the entire function or class being decorated. This implements the feature requested in `issue 131`_. - Multiprocessing support is now available on Windows. Thanks, Rodrigue Cloutier. - Files with two encoding declarations are properly supported, fixing `issue 453`_. Thanks, Max Linke. - Non-ascii characters in regexes in the configuration file worked in 3.7, but stopped working in 4.0. Now they work again, closing `issue 455`_. - Form-feed characters would prevent accurate determination of the beginning of statements in the rest of the file. This is now fixed, closing `issue 461`_. .. _issue 129: https://github.com/nedbat/coveragepy/issues/129 .. _issue 131: https://github.com/nedbat/coveragepy/issues/131 .. _issue 146: https://github.com/nedbat/coveragepy/issues/146 .. _issue 212: https://github.com/nedbat/coveragepy/issues/212 .. _issue 422: https://github.com/nedbat/coveragepy/issues/422 .. _issue 434: https://github.com/nedbat/coveragepy/issues/434 .. _issue 453: https://github.com/nedbat/coveragepy/issues/453 .. _issue 455: https://github.com/nedbat/coveragepy/issues/455 .. _issue 461: https://github.com/nedbat/coveragepy/issues/461 .. _changes_403: ``` ### 4.0.3 ``` ---------------------------- - Fixed a mysterious problem that manifested in different ways: sometimes hanging the process (`issue 420`_), sometimes making database connections fail (`issue 445`_). - The XML report now has correct ``<source>`` elements when using a ``--source=`` option somewhere besides the current directory. This fixes `issue 439`_. Thanks, Arcadiy Ivanov. - Fixed an unusual edge case of detecting source encodings, described in `issue 443`_. - Help messages that mention the command to use now properly use the actual command name, which might be different than "coverage". Thanks to Ben Finney, this closes `issue 438`_. .. _issue 420: https://github.com/nedbat/coveragepy/issues/420 .. _issue 438: https://github.com/nedbat/coveragepy/issues/438 .. _issue 439: https://github.com/nedbat/coveragepy/issues/439 .. _issue 443: https://github.com/nedbat/coveragepy/issues/443 .. _issue 445: https://github.com/nedbat/coveragepy/issues/445 .. _changes_402: ``` ### 4.0.2 ``` ---------------------------- - More work on supporting unusually encoded source. Fixed `issue 431`_. - Files or directories with non-ASCII characters are now handled properly, fixing `issue 432`_. - Setting a trace function with sys.settrace was broken by a change in 4.0.1, as reported in `issue 436`_. This is now fixed. - Officially support PyPy 4.0, which required no changes, just updates to the docs. .. _issue 431: https://github.com/nedbat/coveragepy/issues/431 .. _issue 432: https://github.com/nedbat/coveragepy/issues/432 .. _issue 436: https://github.com/nedbat/coveragepy/issues/436 .. _changes_401: ``` ### 4.0.1 ``` ---------------------------- - When combining data files, unreadable files will now generate a warning instead of failing the command. This is more in line with the older coverage.py v3.7.1 behavior, which silently ignored unreadable files. Prompted by `issue 418`_. - The --skip-covered option would skip reporting on 100% covered files, but also skipped them when calculating total coverage. This was wrong, it should only remove lines from the report, not change the final answer. This is now fixed, closing `issue 423`_. - In 4.0, the data file recorded a summary of the system on which it was run. Combined data files would keep all of those summaries. This could lead to enormous data files consisting of mostly repetitive useless information. That summary is now gone, fixing `issue 415`_. If you want summary information, get in touch, and we'll figure out a better way to do it. - Test suites that mocked os.path.exists would experience strange failures, due to coverage.py using their mock inadvertently. This is now fixed, closing `issue 416`_. - Importing a ``__init__`` module explicitly would lead to an error: ``AttributeError: 'module' object has no attribute '__path__'``, as reported in `issue 410`_. This is now fixed. - Code that uses ``sys.settrace(sys.gettrace())`` used to incur a more than 2x speed penalty. Now there's no penalty at all. Fixes `issue 397`_. - Pyexpat C code will no longer be recorded as a source file, fixing `issue 419`_. - The source kit now contains all of the files needed to have a complete source tree, re-fixing `issue 137`_ and closing `issue 281`_. .. _issue 281: https://github.com/nedbat/coveragepy/issues/281 .. _issue 397: https://github.com/nedbat/coveragepy/issues/397 .. _issue 410: https://github.com/nedbat/coveragepy/issues/410 .. _issue 415: https://github.com/nedbat/coveragepy/issues/415 .. _issue 416: https://github.com/nedbat/coveragepy/issues/416 .. _issue 418: https://github.com/nedbat/coveragepy/issues/418 .. _issue 419: https://github.com/nedbat/coveragepy/issues/419 .. _issue 423: https://github.com/nedbat/coveragepy/issues/423 .. _changes_40: ``` ### 4.0 ``` -------------------------- ``` ### 4.0b3 ``` ---------------------------- - Reporting on an unmeasured file would fail with a traceback. This is now fixed, closing `issue 403`_. - The Jenkins ShiningPanda_ plugin looks for an obsolete file name to find the HTML reports to publish, so it was failing under coverage.py 4.0. Now we create that file if we are running under Jenkins, to keep things working smoothly. `issue 404`_. - Kits used to include tests and docs, but didn't install them anywhere, or provide all of the supporting tools to make them useful. Kits no longer include tests and docs. If you were using them from the older packages, get in touch and help me understand how. .. _issue 403: https://github.com/nedbat/coveragepy/issues/403 .. _issue 404: https://github.com/nedbat/coveragepy/issues/404 ``` ### 4.0b2 ``` ---------------------------- - 4.0b1 broke ``--append`` creating new data files. This is now fixed, closing `issue 392`_. - ``py.test --cov`` can write empty data, then touch files due to ``--source``, which made coverage.py mistakenly force the data file to record lines instead of arcs. This would lead to a "Can't combine line data with arc data" error message. This is now fixed, and changed some method names in the CoverageData interface. Fixes `issue 399`_. - `CoverageData.read_fileobj` and `CoverageData.write_fileobj` replace the `.read` and `.write` methods, and are now properly inverses of each other. - When using ``report --skip-covered``, a message will now be included in the report output indicating how many files were skipped, and if all files are skipped, coverage.py won't accidentally scold you for having no data to report. Thanks, Krystian Kichewko. - A new conversion utility has been added: ``python -m coverage.pickle2json`` will convert v3.x pickle data files to v4.x JSON data files. Thanks, Alexander Todorov. Closes `issue 395`_. - A new version identifier is available, `coverage.version_info`, a plain tuple of values similar to `sys.version_info`_. .. _issue 392: https://github.com/nedbat/coveragepy/issues/392 .. _issue 395: https://github.com/nedbat/coveragepy/issues/395 .. _issue 399: https://github.com/nedbat/coveragepy/issues/399 .. _sys.version_info: https://docs.python.org/3/library/sys.html#sys.version_info ``` ### 4.0b1 ``` ---------------------------- - Coverage.py is now licensed under the Apache 2.0 license. See NOTICE.txt for details. Closes `issue 313`_. - The data storage has been completely revamped. The data file is now JSON-based instead of a pickle, closing `issue 236`_. The `CoverageData` class is now a public supported documented API to the data file. - A new configuration option, ``[run] note``, lets you set a note that will be stored in the `runs` section of the data file. You can use this to annotate the data file with any information you like. - Unrecognized configuration options will now print an error message and stop coverage.py. This should help prevent configuration mistakes from passing silently. Finishes `issue 386`_. - In parallel mode, ``coverage erase`` will now delete all of the data files, fixing `issue 262`_. - Coverage.py now accepts a directory name for ``coverage run`` and will run a ``__main__.py`` found there, just like Python will. Fixes `issue 252`_. Thanks, Dmitry Trofimov. - The XML report now includes a ``missing-branches`` attribute. Thanks, Steve Peak. This is not a part of the Cobertura DTD, so the XML report no longer references the DTD. - Missing branches in the HTML report now have a bit more information in the right-hand annotations. Hopefully this will ma
