For details: https://bitbucket.org/ned/coveragepy/src/default/NOTICE.txt - -============================== -Change history for Coverage.py -============================== - - -Version 4.1 --- 2016-05-21 --------------------------- - -- 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. - - -Version 4.1b3 --- 2016-05-10 ----------------------------- - -- 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 tranfer 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://bitbucket.org/ned/coveragepy/issues/465/coveragexml-produces-package-names-with-an -.. _issue 466: https://bitbucket.org/ned/coveragepy/issues/466/impossible-missed-branch-to-a-negative - - -Version 4.1b1 --- 2016-01-10 ----------------------------- - -- 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 fixes - `issue 439`_. Thanks, Arcady 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".

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://bitbucket.org/ned/coveragepy/issues/431/couldnt-parse-python-file-with-cp1252 -.. _issue 432: https://bitbucket.org/ned/coveragepy/issues/432/path-with-unicode-characters-various -.. _issue 436: https://bitbucket.org/ned/coveragepy/issues/436/disabled-coverage-ctracer-may-rise-from - - -Version 4.0.1 --- 2015-10-13 ----------------------------- - -- 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://bitbucket.org/ned/coveragepy/issues/281/supply-scripts-for-testing-in-the -.. _issue 397: https://bitbucket.org/ned/coveragepy/issues/397/stopping-and-resuming-coverage-with -.. _issue 410: https://bitbucket.org/ned/coveragepy/issues/410/attributeerror-module-object-has-no -.. _issue 415: https://bitbucket.org/ned/coveragepy/issues/415/repeated-coveragedataupdates-cause -.. _issue 416: https://bitbucket.org/ned/coveragepy/issues/416/mocking-ospathexists-causes-failures -.. _issue 418: https://bitbucket.org/ned/coveragepy/issues/418/json-parse-error -.. _issue 419: https://bitbucket.org/ned/coveragepy/issues/419/nosource-no-source-for-code-path-to-c -.. _issue 423: https://bitbucket.org/ned/coveragepy/issues/423/skip_covered-changes-reported-total - - -Version 4.0 --- 2015-09-20 --------------------------- - -No changes from 4.0b3 - - -Version 4.0b3 --- 2015-09-07 ----------------------------- - -- 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://bitbucket.org/ned/coveragepy/issues/403/hasherupdate-fails-with-typeerror-nonetype -.. _issue 404: https://bitbucket.org/ned/coveragepy/issues/404/shiningpanda-jenkins-plugin-cant-find-html - - - -Version 4.0b2 --- 2015-08-22 ----------------------------- - -- 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://bitbucket.org/ned/coveragepy/issues/392/run-append-doesnt-create-coverage-file -.. _issue 395: https://bitbucket.org/ned/coveragepy/issues/395/rfe-read-pickled-files-as-well-for -.. _issue 399: https://bitbucket.org/ned/coveragepy/issues/399/coverageexception-cant-combine-line-data -.. _sys.version_info: https://docs.python.org/3/library/sys.html#sys.version_info - - -Version 4.0b1 --- 2015-08-02 ----------------------------- - -- 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 make their meaning clearer. - -- All the reporting functions now behave the same if no data had been - collected, exiting with a status code of 1. Fixed ``fail_under`` to be - applied even when the report is empty. Thanks, Ionel Cristian Mărieș. - -- Plugins are now initialized differently. Instead of looking for a class - called ``Plugin``, coverage.py looks for a function called ``coverage_init``. - -- A file-tracing plugin can now ask to have built-in Python reporting by - returning `"python"` from its `file_reporter()` method. - -- Code that was executed with `exec` would be mis-attributed to the file that - called it. This is now fixed, closing `issue 380`_. - -- The ability to use item access on `Coverage.config` (introduced in 4.0a2) has - been changed to a more explicit `Coverage.get_option` and - `Coverage.set_option` API. - -- The ``Coverage.use_cache`` method is no longer supported. - -- The private method ``Coverage._harvest_data`` is now called - ``Coverage.get_data``, and returns the ``CoverageData`` containing the - collected data. - -- The project is consistently referred to as "coverage.py" throughout the code - and the documentation, closing `issue 275`_. - -- Combining data files with an explicit configuration file was broken in 4.0a6, - but now works again, closing `issue 385`_. - -- ``coverage combine`` now accepts files as well as directories. - -- The speed is back to 3.7.1 levels, after having slowed down due to plugin - support, finishing up `issue 387`_. - -.. _issue 236: https://bitbucket.org/ned/coveragepy/issues/236/pickles-are-bad-and-you-should-feel-bad -.. _issue 252: https://bitbucket.org/ned/coveragepy/issues/252/coverage-wont-run-a-program-with -.. _issue 262: https://bitbucket.org/ned/coveragepy/issues/262/when-parallel-true-erase-should-erase-all -.. _issue 275: https://bitbucket.org/ned/coveragepy/issues/275/refer-consistently-to-project-as-coverage -.. _issue 313: https://bitbucket.org/ned/coveragepy/issues/313/add-license-file-containing-2-3-or-4 -.. _issue 380: https://bitbucket.org/ned/coveragepy/issues/380/code-executed-by-exec-excluded-from -.. _issue 385: https://bitbucket.org/ned/coveragepy/issues/385/coverage-combine-doesnt-work-with-rcfile -.. _issue 386: https://bitbucket.org/ned/coveragepy/issues/386/error-on-unrecognised-configuration -.. _issue 387: https://bitbucket.org/ned/coveragepy/issues/387/performance-degradation-from-371-to-40 - -.. 40 issues closed in 4.0 below here - - -Version 4.0a6 --- 2015-06-21 ----------------------------- - -- Python 3.5b2 and PyPy 2.6.0 are supported. - -- The original module-level function interface to coverage.py is no longer - supported. You must now create a ``coverage.Coverage`` object, and use - methods on it. - -- The ``coverage combine`` command now accepts any number of directories as - arguments, and will combine all the data files from those directories. This - means you don't have to copy the files to one directory before combining. - Thanks, Christine Lytwynec. Finishes `issue 354`_. - -- Branch coverage couldn't properly handle certain extremely long files. This - is now fixed (`issue 359`_). - -- Branch coverage didn't understand yield statements properly. Mickie Betz - persisted in pursuing this despite Ned's pessimism. Fixes `issue 308`_ and - `issue 324`_. - -- The COVERAGE_DEBUG environment variable can be used to set the ``[run] debug`` - configuration option to control what internal operations are logged. - -- HTML reports were truncated at formfeed characters. This is now fixed - (`issue 360`_). It's always fun when the problem is due to a `bug in the - Python standard library <http://bugs.python.org/issue19035>`_. - -- Files with incorrect encoding declaration comments are no longer ignored by - the reporting commands, fixing `issue 351`_. - -- HTML reports now include a timestamp in the footer, closing `issue 299`_. - Thanks, Conrad Ho. - -- HTML reports now begrudgingly use double-quotes rather than single quotes, - because there are "software engineers" out there writing tools that read HTML - and somehow have no idea that single quotes exist. Capitulates to the absurd - `issue 361`_. Thanks, Jon Chappell. - -- The ``coverage annotate`` command now handles non-ASCII characters properly, - closing `issue 363`_. Thanks, Leonardo Pistone. - -- Drive letters on Windows were not normalized correctly, now they are. Thanks, - Ionel Cristian Mărieș. - -- Plugin support had some bugs fixed, closing `issue 374`_ and `issue 375`_. - Thanks, Stefan Behnel. - -.. _issue 299: https://bitbucket.org/ned/coveragepy/issue/299/inserted-created-on-yyyy-mm-dd-hh-mm-in -.. _issue 308: https://bitbucket.org/ned/coveragepy/issue/308/yield-lambda-branch-coverage -.. _issue 324: https://bitbucket.org/ned/coveragepy/issue/324/yield-in-loop-confuses-branch-coverage -.. _issue 351: https://bitbucket.org/ned/coveragepy/issue/351/files-with-incorrect-encoding-are-ignored -.. _issue 354: https://bitbucket.org/ned/coveragepy/issue/354/coverage-combine-should-take-a-list-of -.. _issue 359: https://bitbucket.org/ned/coveragepy/issue/359/xml-report-chunk-error -.. _issue 360: https://bitbucket.org/ned/coveragepy/issue/360/html-reports-get-confused-by-l-in-the-code -.. _issue 361: https://bitbucket.org/ned/coveragepy/issue/361/use-double-quotes-in-html-output-to -.. _issue 363: https://bitbucket.org/ned/coveragepy/issue/363/annotate-command-hits-unicode-happy-fun -.. _issue 374: https://bitbucket.org/ned/coveragepy/issue/374/c-tracer-lookups-fail-in -.. _issue 375: https://bitbucket.org/ned/coveragepy/issue/375/ctracer_handle_return-reads-byte-code - - -Version 4.0a5 --- 2015-02-16 ----------------------------- - -- Plugin support is now implemented in the C tracer instead of the Python - tracer. This greatly improves the speed of tracing projects using plugins. - -- Coverage.py now always adds the current directory to sys.path, so that - plugins can import files in the current directory (`issue 358`_). - -- If the `config_file` argument to the Coverage constructor is specified as - ".coveragerc", it is treated as if it were True. This means setup.cfg is - also examined, and a missing file is not considered an error (`issue 357`_). - -- Wildly experimental: support for measuring processes started by the - multiprocessing module. To use, set ``--concurrency=multiprocessing``, - either on the command line or in the .coveragerc file (`issue 117`_). Thanks, - Eduardo Schettino. Currently, this does not work on Windows. - -- A new warning is possible, if a desired file isn't measured because it was - imported before coverage.py was started (`issue 353`_). - -- The `coverage.process_startup` function now will start coverage measurement - only once, no matter how many times it is called. This fixes problems due - to unusual virtualenv configurations (`issue 340`_). - -- Added 3.5.0a1 to the list of supported CPython versions. - -.. _issue 117: https://bitbucket.org/ned/coveragepy/issue/117/enable-coverage-measurement-of-code-run-by -.. _issue 340: https://bitbucket.org/ned/coveragepy/issue/340/keyerror-subpy -.. _issue 353: https://bitbucket.org/ned/coveragepy/issue/353/40a3-introduces-an-unexpected-third-case -.. _issue 357: https://bitbucket.org/ned/coveragepy/issue/357/behavior-changed-when-coveragerc-is -.. _issue 358: https://bitbucket.org/ned/coveragepy/issue/358/all-coverage-commands-should-adjust - - -Version 4.0a4 --- 2015-01-25 ----------------------------- - -- Plugins can now provide sys_info for debugging output. - -- Started plugins documentation. - -- Prepared to move the docs to readthedocs.org. - - -Version 4.0a3 --- 2015-01-20 ----------------------------- - -- Reports now use file names with extensions. Previously, a report would - describe a/b/c.py as "a/b/c". Now it is shown as "a/b/c.py". This allows - for better support of non-Python files, and also fixed `issue 69`_. - -- The XML report now reports each directory as a package again. This was a bad - regression, I apologize. This was reported in `issue 235`_, which is now - fixed. - -- A new configuration option for the XML report: ``[xml] package_depth`` - controls which directories are identified as packages in the report. - Directories deeper than this depth are not reported as packages. - The default is that all directories are reported as packages. - Thanks, Lex Berezhny. - -- When looking for the source for a frame, check if the file exists. On - Windows, .pyw files are no longer recorded as .py files. Along the way, this - fixed `issue 290`_. - -- Empty files are now reported as 100% covered in the XML report, not 0% - covered (`issue 345`_). - -- Regexes in the configuration file are now compiled as soon as they are read, - to provide error messages earlier (`issue 349`_). - -.. _issue 69: https://bitbucket.org/ned/coveragepy/issue/69/coverage-html-overwrite-files-that-doesnt -.. _issue 235: https://bitbucket.org/ned/coveragepy/issue/235/package-name-is-missing-in-xml-report -.. _issue 290: https://bitbucket.org/ned/coveragepy/issue/290/running-programmatically-with-pyw-files -.. _issue 345: https://bitbucket.org/ned/coveragepy/issue/345/xml-reports-line-rate-0-for-empty-files -.. _issue 349: https://bitbucket.org/ned/coveragepy/issue/349/bad-regex-in-config-should-get-an-earlier - - -Version 4.0a2 --- 2015-01-14 ----------------------------- - -- Officially support PyPy 2.4, and PyPy3 2.4. Drop support for - CPython 3.2 and older versions of PyPy. The code won't work on CPython 3.2. - It will probably still work on older versions of PyPy, but I'm not testing - against them. - -- Plugins! - -- The original command line switches (`-x` to run a program, etc) are no - longer supported. - -- A new option: `coverage report --skip-covered` will reduce the number of - files reported by skipping files with 100% coverage. Thanks, Krystian - Kichewko. This means that empty `__init__.py` files will be skipped, since - they are 100% covered, closing `issue 315`_. - -- You can now specify the ``--fail-under`` option in the ``.coveragerc`` file - as the ``[report] fail_under`` option. This closes `issue 314`_. - -- The ``COVERAGE_OPTIONS`` environment variable is no longer supported. It was - a hack for ``--timid`` before configuration files were available. - -- The HTML report now has filtering. Type text into the Filter box on the - index page, and only modules with that text in the name will be shown. - Thanks, Danny Allen. - -- The textual report and the HTML report used to report partial branches - differently for no good reason. Now the text report's "missing branches" - column is a "partial branches" column so that both reports show the same - numbers. This closes `issue 342`_. - -- If you specify a ``--rcfile`` that cannot be read, you will get an error - message. Fixes `issue 343`_. - -- The ``--debug`` switch can now be used on any command. - -- You can now programmatically adjust the configuration of coverage.py by - setting items on `Coverage.config` after construction. - -- A module run with ``-m`` can be used as the argument to ``--source``, fixing - `issue 328`_. Thanks, Buck Evan. - -- The regex for matching exclusion pragmas has been fixed to allow more kinds - of whitespace, fixing `issue 334`_. - -- Made some PyPy-specific tweaks to improve speed under PyPy. Thanks, Alex - Gaynor. - -- In some cases, with a source file missing a final newline, coverage.py would - count statements incorrectly. This is now fixed, closing `issue 293`_. - -- The status.dat file that HTML reports use to avoid re-creating files that - haven't changed is now a JSON file instead of a pickle file.

Huge - thanks to Peter Portante for initial implementation, and to Joe Jevnik for - the final insight that completed the work. - -- Options are now also read from a setup.cfg file, if any. Sections are - prefixed with "coverage:", so the ``[run]`` options will be read from the - ``[coverage:run]`` section of setup.cfg. Finishes `issue 304`_. - -- The ``report -m`` command can now show missing branches when reporting on - branch coverage. Thanks, Steve Leonard. Closes `issue 230`_. - -- The XML report now contains a <source> element, fixing `issue 94`_. Thanks - Stan Hu. - -- The class defined in the coverage module is now called ``Coverage`` instead - of ``coverage``, though the old name still works, for backward compatibility. - -- The ``fail-under`` value is now rounded the same as reported results, - preventing paradoxical results, fixing `issue 284`_. - -- The XML report will now create the output directory if need be, fixing - `issue 285`_. Thanks, Chris Rose. - -- HTML reports no longer raise UnicodeDecodeError if a Python file has - undecodable characters, fixing `issue 303`_ and `issue 331`_. - -- The annotate command will now annotate all files, not just ones relative to - the current directory, fixing `issue 57`_. - -- The coverage module no longer causes deprecation warnings on Python 3.4 by - importing the imp module, fixing `issue 305`_. - -- Encoding declarations in source files are only considered if they are truly - comments.

It no longer does. - -- ``debug sys`` now shows the configuration file path that was read. - -- If an oddly-behaved package claims that code came from an empty-string - file name, coverage.py no longer associates it with the directory name, - fixing `issue 221`_. - -.. _issue 221: https://bitbucket.org/ned/coveragepy/issue/221/coveragepy-incompatible-with-pyratemp - - -Version 3.6b1 --- 2012-11-28 ----------------------------- - -- Wildcards in ``include=`` and ``omit=`` arguments were not handled properly - in reporting functions, though they were when running. Now they are handled - uniformly, closing `issue 143`_ and `issue 163`_. **NOTE**: it is possible - that your configurations may now be incorrect. If you use ``include`` or - ``omit`` during reporting, whether on the command line, through the API, or - in a configuration file, please check carefully that you were not relying on - the old broken behavior. - -- The **report**, **html**, and **xml** commands now accept a ``--fail-under`` - switch that indicates in the exit status whether the coverage percentage was - less than a particular value. Closes `issue 139`_. - -- The reporting functions coverage.report(), coverage.html_report(), and - coverage.xml_report() now all return a float, the total percentage covered - measurement. - -- The HTML report's title can now be set in the configuration file, with the - ``--title`` switch on the command line, or via the API. - -- Configuration files now support substitution of environment variables, using - syntax like ``${WORD}``. Closes `issue 97`_. - -- Embarrassingly, the ``[xml] output=`` setting in the .coveragerc file simply - didn't work. Now it does. - -- The XML report now consistently uses file names for the file name attribute, - rather than sometimes using module names. Fixes `issue 67`_. - Thanks, Marcus Cobden. - -- Coverage percentage metrics are now computed slightly differently under - branch coverage. This means that completely unexecuted files will now - correctly have 0% coverage, fixing `issue 156`_. This also means that your - total coverage numbers will generally now be lower if you are measuring - branch coverage. - -- When installing, now in addition to creating a "coverage" command, two new - aliases are also installed. A "coverage2" or "coverage3" command will be - created, depending on whether you are installing in Python 2.x or 3.x. - A "coverage-X.Y" command will also be created corresponding to your specific - version of Python. Closes `issue 111`_. - -- The coverage.py installer no longer tries to bootstrap setuptools or - Distribute. You must have one of them installed first, as `issue 202`_ - recommended. - -- The coverage.py kit now includes docs (closing `issue 137`_) and tests. - -- On Windows, files are now reported in their correct case, fixing `issue 89`_ - and `issue 203`_. - -- If a file is missing during reporting, the path shown in the error message - is now correct, rather than an incorrect path in the current directory. - Fixes `issue 60`_. - -- Running an HTML report in Python 3 in the same directory as an old Python 2 - HTML report would fail with a UnicodeDecodeError. This issue (`issue 193`_) - is now fixed. - -- Fixed yet another error trying to parse non-Python files as Python, this - time an IndentationError, closing `issue 82`_ for the fourth time... - -- If `coverage xml` fails because there is no data to report, it used to - create a zero-length XML file. Now it doesn't, fixing `issue 210`_. - -- Jython files now work with the ``--source`` option, fixing `issue 100`_. - -- Running coverage.py under a debugger is unlikely to work, but it shouldn't - fail with "TypeError: 'NoneType' object is not iterable". Fixes `issue - 201`_. - -- On some Linux distributions, when installed with the OS package manager, - coverage.py would report its own code as part of the results. Now it won't, - fixing `issue 214`_, though this will take some time to be repackaged by the - operating systems. - -- Docstrings for the legacy singleton methods are more helpful. Thanks Marius - Gedminas. Closes `issue 205`_. - -- The pydoc tool can now show documentation for the class `coverage.coverage`. - Closes `issue 206`_. - -- Added a page to the docs about contributing to coverage.py, closing - `issue 171`_. - -- When coverage.py ended unsuccessfully, it may have reported odd errors like - ``'NoneType' object has no attribute 'isabs'``.

Thanks, Guido van Rossum. - - -Version 3.5b1 --- 2011-06-05 ----------------------------- - -- The HTML report now has hotkeys. Try ``n``, ``s``, ``m``, ``x``, ``b``, - ``p``, and ``c`` on the overview page to change the column sorting. - On a file page, ``r``, ``m``, ``x``, and ``p`` toggle the run, missing, - excluded, and partial line markings. You can navigate the highlighted - sections of code by using the ``j`` and ``k`` keys for next and previous. - The ``1`` (one) key jumps to the first highlighted section in the file, - and ``0`` (zero) scrolls to the top of the file. - -- The ``--omit`` and ``--include`` switches now interpret their values more - usefully. If the value starts with a wildcard character, it is used as-is. - If it does not, it is interpreted relative to the current directory. - Closes `issue 121`_. - -- Partial branch warnings can now be pragma'd away. The configuration option - ``partial_branches`` is a list of regular expressions. Lines matching any of - those expressions will never be marked as a partial branch. In addition, - there's a built-in list of regular expressions marking statements which should - never be marked as partial. This list includes ``while True:``, ``while 1:``, - ``if 1:``, and ``if 0:``. - -- The ``coverage()`` constructor accepts single strings for the ``omit=`` and - ``include=`` arguments, adapting to a common error in programmatic use. - -- Modules can now be run directly using ``coverage run -m modulename``, to - mirror Python's ``-m`` flag. Closes `issue 95`_, thanks, Brandon Rhodes. - -- ``coverage run`` didn't emulate Python accurately in one small detail: the - current directory inserted into ``sys.path`` was relative rather than - absolute. This is now fixed. - -- HTML reporting is now incremental: a record is kept of the data that - produced the HTML reports, and only files whose data has changed will - be generated. This should make most HTML reporting faster. - -- Pathological code execution could disable the trace function behind our - backs, leading to incorrect code measurement. Now if this happens, - coverage.py will issue a warning, at least alerting you to the problem. - Closes `issue 93`_. Thanks to Marius Gedminas for the idea. - -- The C-based trace function now behaves properly when saved and restored - with ``sys.gettrace()`` and ``sys.settrace()``. This fixes `issue 125`_ - and `issue 123`_. Thanks, Devin Jeanpierre. - -- Source files are now opened with Python 3.2's ``tokenize.open()`` where - possible, to get the best handling of Python source files with encodings. - Closes `issue 107`_, thanks, Brett Cannon. - -- Syntax errors in supposed Python files can now be ignored during reporting - with the ``-i`` switch just like other source errors.

Thanks, Adi Roiban. - Jython still doesn't provide the Python libraries needed to make - coverage reporting work, unfortunately. - -- Internally, files are now closed explicitly, fixing `issue 104`_.

A parallel argument `include` controls what files are included. - -- The run command now has a ``--source`` switch, a list of directories or - module names. If provided, coverage.py will only measure execution in those - source files. - -- Various warnings are printed to stderr for problems encountered during data - measurement: if a ``--source`` module has no Python source to measure, or is - never encountered at all, or if no data is collected. - -- The reporting commands (report, annotate, html, and xml) now have an - ``--include`` switch to restrict reporting to modules matching those file - patterns, similar to the existing ``--omit`` switch. Thanks, Zooko. - -- The run command now supports ``--include`` and ``--omit`` to control what - modules it measures. This can speed execution and reduce the amount of data - during reporting. Thanks Zooko. - -- Since coverage.py 3.1, using the Python trace function has been slower than - it needs to be. A cache of tracing decisions was broken, but has now been - fixed. - -- Python 2.7 and 3.2 have introduced new opcodes that are now supported. - -- Python files with no statements, for example, empty ``__init__.py`` files, - are now reported as having zero statements instead of one. Fixes `issue 1`_. - -- Reports now have a column of missed line counts rather than executed line - counts, since developers should focus on reducing the missed lines to zero, - rather than increasing the executed lines to varying targets. Once - suggested, this seemed blindingly obvious. - -- Line numbers in HTML source pages are clickable, linking directly to that - line, which is highlighted on arrival. Added a link back to the index page - at the bottom of each HTML page. - -- Programs that call ``os.fork`` will properly collect data from both the child - and parent processes. Use ``coverage run -p`` to get two data files that can - be combined with ``coverage combine``. Fixes `issue 56`_. - -- Coverage.py is now runnable as a module: ``python -m coverage``. Thanks, - Brett Cannon. - -- When measuring code running in a virtualenv, most of the system library was - being measured when it shouldn't have been. This is now fixed. - -- Doctest text files are no longer recorded in the coverage data, since they - can't be reported anyway. Fixes `issue 52`_ and `issue 61`_. - -- Jinja HTML templates compile into Python code using the HTML file name, - which confused coverage.py. Now these files are no longer traced, fixing - `issue 82`_. - -- Source files can have more than one dot in them (foo.test.py), and will be - treated properly while reporting. Fixes `issue 46`_. - -- Source files with DOS line endings are now properly tokenized for syntax - coloring on non-DOS machines. Fixes `issue 53`_. - -- Unusual code structure that confused exits from methods with exits from - classes is now properly analyzed. See `issue 62`_. - -- Asking for an HTML report with no files now shows a nice error message rather - than a cryptic failure ('int' object is unsubscriptable).

Thanks, Christian Heimes. - -.. _issue 6: http://bitbucket.org/ned/coveragepy/issue/6 - - -Version 3.0b3 --- 2009-05-16 ----------------------------- - -- Added parameters to coverage.__init__ for options that had been set on the - coverage object itself. - -- Added clear_exclude() and get_exclude_list() methods for programmatic - manipulation of the exclude regexes. - -- Added coverage.load() to read previously-saved data from the data file. - -- Improved the finding of code files. For example, .pyc files that have been - installed after compiling are now located correctly. Thanks, Detlev - Offenbach. - -- When using the object API (that is, constructing a coverage() object), data - is no longer saved automatically on process exit. You can re-enable it with - the auto_data=True parameter on the coverage() constructor. The module-level - interface still uses automatic saving. - - -Version 3.0b --- 2009-04-30 ---------------------------- - -HTML reporting, and continued refactoring. - -- HTML reports and annotation of source files: use the new -b (browser) switch. - Thanks to George Song for code, inspiration and guidance. - -- Code in the Python standard library is not measured by default. If you need - to measure standard library code, use the -L command-line switch during - execution, or the cover_pylib=True argument to the coverage() constructor. - -- Source annotation into a directory (-a -d) behaves differently. The - annotated files are named with their hierarchy flattened so that same-named - files from different directories no longer collide. Also, only files in the - current tree are included. - -- coverage.annotate_file is no longer available. - -- Programs executed with -x now behave more as they should, for example, - __file__ has the correct value. - -- .coverage data files have a new pickle-based format designed for better - extensibility. - -- Removed the undocumented cache_file argument to coverage.usecache(). - - -Version 3.0b1 --- 2009-03-07 ----------------------------- - -Major overhaul. - -- Coverage.py is now a package rather than a module. Functionality has been - split into classes. - -- The trace function is implemented in C for speed. Coverage.py runs are now - much faster. Thanks to David Christian for productive micro-sprints and - other encouragement. - -- Executable lines are identified by reading the line number tables in the - compiled code, removing a great deal of complicated analysis code. - -- Precisely which lines are considered executable has changed in some cases. - Therefore, your coverage stats may also change slightly. - -- The singleton coverage object is only created if the module-level functions - are used. This maintains the old interface while allowing better - programmatic use of Coverage.py. - -- The minimum supported Python version is 2.3. - - -Version 2.85 --- 2008-09-14 ---------------------------- - -- Add support for finding source files in eggs. Don't check for - morf's being instances of ModuleType, instead use duck typing so that - pseudo-modules can participate. Thanks, Imri Goldberg. - -- Use os.realpath as part of the fixing of file names so that symlinks won't - confuse things. Thanks, Patrick Mezard. - - -Version 2.80 --- 2008-05-25 ---------------------------- - -- Open files in rU mode to avoid line ending craziness. Thanks, Edward Loper. - - -Version 2.78 --- 2007-09-30 ---------------------------- - -- Don't try to predict whether a file is Python source based on the extension. - Extension-less files are often Pythons scripts. Instead, simply parse the file - and catch the syntax errors. Hat tip to Ben Finney. - - -Version 2.77 --- 2007-07-29 ---------------------------- - -- Better packaging. - - -Version 2.76 --- 2007-07-23 ---------------------------- - -- Now Python 2.5 is *really* fully supported: the body of the new with - statement is counted as executable. - - -Version 2.75 --- 2007-07-22 ---------------------------- - -- Python 2.5 now fully supported. The method of dealing with multi-line - statements is now less sensitive to the exact line that Python reports during - execution. Pass statements are handled specially so that their disappearance - during execution won't throw off the measurement. - - -Version 2.7 --- 2007-07-21 --------------------------- - -- "#pragma: nocover" is excluded by default. - -- Properly ignore docstrings and other constant expressions that appear in the - middle of a function, a problem reported by Tim Leslie. - -- coverage.erase() shouldn't clobber the exclude regex. Change how parallel - mode is invoked, and fix erase() so that it erases the cache when called - programmatically. - -- In reports, ignore code executed from strings, since we can't do anything - useful with it anyway. - -- Better file handling on Linux, thanks Guillaume Chazarain. - -- Better shell support on Windows, thanks Noel O'Boyle. - -- Python 2.2 support maintained, thanks Catherine Proulx. - -- Minor changes to avoid lint warnings. - - -Version 2.6 --- 2006-08-23 --------------------------- - -- Applied Joseph Tate's patch for function decorators. - -- Applied Sigve Tjora and Mark van der Wal's fixes for argument handling. - -- Applied Geoff Bache's parallel mode patch. - -- Refactorings to improve testability. Fixes to command-line logic for parallel - mode and collect. - - -Version 2.5 --- 2005-12-04 --------------------------- - -- Call threading.settrace so that all threads are measured. Thanks Martin - Fuzzey. - -- Add a file argument to report so that reports can be captured to a different - destination. - -- Coverage.py can now measure itself. - -- Adapted Greg Rogers' patch for using relative file names, and sorting and - omitting files to report on. - - -Version 2.2 --- 2004-12-31 --------------------------- - -- Allow for keyword arguments in the module global functions. Thanks, Allen. - - -Version 2.1 --- 2004-12-14 --------------------------- - -- Return 'analysis' to its original behavior and add 'analysis2'. Add a global - for 'annotate', and factor it, adding 'annotate_file'. - - -Version 2.0 --- 2004-12-12 --------------------------- - -Significant code changes. - -- Finding executable statements has been rewritten so that docstrings and - other quirks of Python execution aren't mistakenly identified as missing - lines. - -- Lines can be excluded from consideration, even entire suites of lines. - -- The file system cache of covered lines can be disabled programmatically. - -- Modernized the code. - - -Earlier History ---------------- - -2001-12-04 GDR Created. - -2001-12-06 GDR Added command-line interface and source code annotation. - -2001-12-09 GDR Moved design and interface to separate documents. - -2001-12-10 GDR Open cache file as binary on Windows.
