For a more complete change history, see the `CHANGES.txt`_ file in the source tree. .. _CHANGES.txt: http://bitbucket.org/ned/coveragepy/src/tip/CHANGES.txt .. _changes_371: Version 3.7.1 --- 13 December 2013 ---------------------------------- - Improved the speed of HTML report generation by about 20%. - Fixed the mechanism for finding OS-installed static files for the HTML report so that it will actually find OS-installed static files. .. _changes_37: Version 3.7 --- 6 October 2013 ------------------------------ - Added the ``--debug`` switch to ``coverage run``. It accepts a list of options indicating the type of internal activity to log to stderr. For details, see :ref:`the run --debug options `. - Improved the branch coverage facility, fixing `issue 92`_ and `issue 175`_. - Running code with ``coverage run -m`` now behaves more like Python does, setting sys.path properly, which fixes `issue 207`_ and `issue 242`_. - Coverage can now run .pyc files directly, closing `issue 264`_. - Coverage properly supports .pyw files, fixing `issue 261`_. - Omitting files within a tree specified with the ``source`` option would cause them to be incorrectly marked as unexecuted, as described in `issue 218`_. This is now fixed. - When specifying paths to alias together during data combining, you can now specify relative paths, fixing `issue 267`_. - Most file paths can now be specified with username expansion (``~/src``, or ``~build/src``, for example), and with environment variable expansion (``build/$BUILDNUM/src``). - Trying to create an XML report with no files to report on, would cause a ZeroDivideError, but no longer does, fixing `issue 250`_. - When running a threaded program under the Python tracer, coverage no longer issues a spurious warning about the trace function changing: "Trace function changed, measurement is likely wrong: None." This fixes `issue 164`_. - Static files necessary for HTML reports are found in system-installed places, to ease OS-level packaging of coverage.py. Closes `issue 259`_. - Source files with encoding declarations, but a blank first line, were not decoded properly. Now they are. Thanks, Roger Hu. - The source kit now includes the ``__main__.py`` file in the root coverage directory, fixing `issue 255`_. .. _issue 92: https://bitbucket.org/ned/coveragepy/issue/92/finally-clauses-arent-treated-properly-in .. _issue 164: https://bitbucket.org/ned/coveragepy/issue/164/trace-function-changed-warning-when-using .. _issue 175: https://bitbucket.org/ned/coveragepy/issue/175/branch-coverage-gets-confused-in-certain .. _issue 207: https://bitbucket.org/ned/coveragepy/issue/207/run-m-cannot-find-module-or-package-in .. _issue 242: https://bitbucket.org/ned/coveragepy/issue/242/running-a-two-level-package-doesnt-work .. _issue 218: https://bitbucket.org/ned/coveragepy/issue/218/run-command-does-not-respect-the-omit-flag .. _issue 250: https://bitbucket.org/ned/coveragepy/issue/250/uncaught-zerodivisionerror-when-generating .. _issue 255: https://bitbucket.org/ned/coveragepy/issue/255/directory-level-__main__py-not-included-in .. _issue 259: https://bitbucket.org/ned/coveragepy/issue/259/allow-use-of-system-installed-third-party .. _issue 261: https://bitbucket.org/ned/coveragepy/issue/261/pyw-files-arent-reported-properly .. _issue 264: https://bitbucket.org/ned/coveragepy/issue/264/coverage-wont-run-pyc-files .. _issue 267: https://bitbucket.org/ned/coveragepy/issue/267/relative-path-aliases-dont-work Version 3.6 --- 5 January 2013 ------------------------------ Features: - 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`_. Packaging: - The C extension is optionally compiled using a different more widely-used technique, taking another stab at fixing `issue 80`_ once and for all. - 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. Docs: - Added a page to the docs about :doc:`contributing ` to coverage.py, closing `issue 171`_. - Added a page to the docs about :doc:`troublesome situations `, closing `issue 226`_. - Docstrings for the legacy singleton methods are more helpful. Thanks Marius Gedminas. Closes `issue 205`_. - The pydoc tool can now show docmentation for the class `coverage.coverage`. Closes `issue 206`_. - Added some info to the TODO file, closing `issue 227`_. Fixes: - 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. - Embarrassingly, the `[xml] output=` setting in the .coveragerc file simply didn't work. Now it does. - Combining data files would create entries for phantom files if used with ``source`` and path aliases. 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 filename, coverage.py no longer associates it with the directory name, fixing `issue 221`_. - The XML report now consistently uses filenames for the filename 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. - 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 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. - When coverage.py ended unsuccessfully, it may have reported odd errors like ``'NoneType' object has no attribute 'isabs'``. It no longer does, so kiss `issue 153`_ goodbye. .. _issue 60: https://bitbucket.org/ned/coveragepy/issue/60/incorrect-path-to-orphaned-pyc-files .. _issue 67: https://bitbucket.org/ned/coveragepy/issue/67/xml-report-filenames-may-be-generated .. _issue 80: https://bitbucket.org/ned/coveragepy/issue/80/is-there-a-duck-typing-way-to-know-we-cant .. _issue 82: https://bitbucket.org/ned/coveragepy/issue/82/tokenerror-when-generating-html-report .. _issue 89: https://bitbucket.org/ned/coveragepy/issue/89/on-windows-all-packages-are-reported-in .. _issue 97: https://bitbucket.org/ned/coveragepy/issue/97/allow-environment-variables-to-be .. _issue 100: https://bitbucket.org/ned/coveragepy/issue/100/source-directive-doesnt-work-for-packages .. _issue 111: https://bitbucket.org/ned/coveragepy/issue/111/when-installing-coverage-with-pip-not .. _issue 137: https://bitbucket.org/ned/coveragepy/issue/137/provide-docs-with-source-distribution .. _issue 139: https://bitbucket.org/ned/coveragepy/issue/139/easy-check-for-a-certain-coverage-in-tests .. _issue 143: https://bitbucket.org/ned/coveragepy/issue/143/omit-doesnt-seem-to-work-in-coverage .. _issue 153: https://bitbucket.org/ned/coveragepy/issue/153/non-existent-filename-triggers .. _issue 156: https://bitbucket.org/ned/coveragepy/issue/156/a-completely-unexecuted-file-shows-14 .. _issue 163: https://bitbucket.org/ned/coveragepy/issue/163/problem-with-include-and-omit-filename .. _issue 171: https://bitbucket.org/ned/coveragepy/issue/171/how-to-contribute-and-run-tests .. _issue 193: https://bitbucket.org/ned/coveragepy/issue/193/unicodedecodeerror-on-htmlpy .. _issue 201: https://bitbucket.org/ned/coveragepy/issue/201/coverage-using-django-14-with-pydb-on .. _issue 202: https://bitbucket.org/ned/coveragepy/issue/202/get-rid-of-ez_setuppy-and .. _issue 203: https://bitbucket.org/ned/coveragepy/issue/203/duplicate-filenames-reported-when-filename .. _issue 205: https://bitbucket.org/ned/coveragepy/issue/205/make-pydoc-coverage-more-friendly .. _issue 206: https://bitbucket.org/ned/coveragepy/issue/206/pydoc-coveragecoverage-fails-with-an-error .. _issue 210: https://bitbucket.org/ned/coveragepy/issue/210/if-theres-no-coverage-data-coverage-xml .. _issue 214: https://bitbucket.org/ned/coveragepy/issue/214/coveragepy-measures-itself-on-precise .. _issue 221: https://bitbucket.org/ned/coveragepy/issue/221/coveragepy-incompatible-with-pyratemp .. _issue 226: https://bitbucket.org/ned/coveragepy/issue/226/make-readme-section-to-describe-when .. _issue 227: https://bitbucket.org/ned/coveragepy/issue/227/update-todo Version 3.5.3 --- 29 September 2012 ----------------------------------- - Line numbers in the HTML report line up better with the source lines, fixing `issue 197`_, thanks Marius Gedminas. - When specifying a directory as the source= option, the directory itself no longer needs to have a ``__init__.py`` file, though its subdirectories do, to be considered as source files. - Files encoded as UTF-8 with a BOM are now properly handled, fixing `issue 179`_. Thanks, Pablo Carballo. - Fixed more cases of non-Python files being reported as Python source, and then not being able to parse them as Python. Closes `issue 82`_ (again). Thanks, Julian Berman. - Fixed memory leaks under Python 3, thanks, Brett Cannon. Closes `issue 147`_. - Optimized .pyo files may not have been handled correctly, `issue 195`_. Thanks, Marius Gedminas. - Certain unusually named file paths could have been mangled during reporting, `issue 194`_. Thanks, Marius Gedminas. - Try to do a better job of the impossible task of detecting when we can't build the C extension, fixing `issue 183`_. .. _issue 82: https://bitbucket.org/ned/coveragepy/issue/82/tokenerror-when-generating-html-report .. _issue 147: https://bitbucket.org/ned/coveragepy/issue/147/massive-memory-usage-by-ctracer .. _issue 179: https://bitbucket.org/ned/coveragepy/issue/179/htmlreporter-fails-when-source-file-is .. _issue 183: https://bitbucket.org/ned/coveragepy/issue/183/install-fails-for-python-23 .. _issue 194: https://bitbucket.org/ned/coveragepy/issue/194/filelocatorrelative_filename-could-mangle .. _issue 195: https://bitbucket.org/ned/coveragepy/issue/195/pyo-file-handling-in-codeunit .. _issue 197: https://bitbucket.org/ned/coveragepy/issue/197/line-numbers-in-html-report-do-not-align Version 3.5.2 --- 4 May 2012 ---------------------------- - The HTML report has slightly tweaked controls: the buttons at the top of the page are color-coded to the source lines they affect. - Custom CSS can be applied to the HTML report by specifying a CSS file as the extra_css configuration value in the [html] section. - Source files with custom encodings declared in a comment at the top are now properly handled during reporting on Python 2. Python 3 always handled them properly. This fixes `issue 157`_. - Backup files left behind by editors are no longer collected by the source= option, fixing `issue 168`_. - If a file doesn't parse properly as Python, we don't report it as an error if the filename seems like maybe it wasn't meant to be Python. This is a pragmatic fix for `issue 82`_. - The ``-m`` switch on ``coverage report``, which includes missing line numbers in the summary report, can now be specifed as ``show_missing`` in the config file. Closes `issue 173`_. - When running a module with ``coverage run -m ``, certain details of the execution environment weren't the same as for ``python -m ``. This had the unfortunate side-effect of making ``coverage run -m unittest discover`` not work if you had tests in a directory named "test". This fixes `issue 155`_. - Now the exit status of your product code is properly used as the process status when running ``python -m coverage run ...``. Thanks, JT Olds. - When installing into pypy, we no longer attempt (and fail) to compile the C tracer function, closing `issue 166`_. .. _issue 82: https://bitbucket.org/ned/coveragepy/issue/82/tokenerror-when-generating-html-report .. _issue 155: https://bitbucket.org/ned/coveragepy/issue/155/cant-use-coverage-run-m-unittest-discover .. _issue 157: https://bitbucket.org/ned/coveragepy/issue/157/chokes-on-source-files-with-non-utf-8 .. _issue 166: https://bitbucket.org/ned/coveragepy/issue/166/dont-try-to-compile-c-extension-on-pypy .. _issue 168: https://bitbucket.org/ned/coveragepy/issue/168/dont-be-alarmed-by-emacs-droppings .. _issue 173: https://bitbucket.org/ned/coveragepy/issue/173/theres-no-way-to-specify-show-missing-in Version 3.5.1 --- 23 September 2011 ----------------------------------- - When combining data files from parallel runs, you can now instruct coverage about which directories are equivalent on different machines. A ``[paths]`` section in the configuration file lists paths that are to be considered equivalent. Finishes `issue 17`_. - for-else constructs are understood better, and don't cause erroneous partial branch warnings. Fixes `issue 122`_. - Branch coverage for ``with`` statements is improved, fixing `issue 128`_. - The number of partial branches reported on the HTML summary page was different than the number reported on the individual file pages. This is now fixed. - An explicit include directive to measure files in the Python installation wouldn't work because of the standard library exclusion. Now the include directive takes precendence, and the files will be measured. Fixes `issue 138`_. - The HTML report now handles Unicode characters in Python source files properly. This fixes `issue 124`_ and `issue 144`_. Thanks, Devin Jeanpierre. - In order to help the core developers measure the test coverage of the standard library, Brandon Rhodes devised an aggressive hack to trick Python into running some coverage code before anything else in the process. See the coverage/fullcoverage directory if you are interested. .. _issue 17: http://bitbucket.org/ned/coveragepy/issue/17/support-combining-coverage-data-from .. _issue 122: http://bitbucket.org/ned/coveragepy/issue/122/for-else-always-reports-missing-branch .. _issue 124: http://bitbucket.org/ned/coveragepy/issue/124/no-arbitrary-unicode-in-html-reports-in .. _issue 128: http://bitbucket.org/ned/coveragepy/issue/128/branch-coverage-of-with-statement-in-27 .. _issue 138: http://bitbucket.org/ned/coveragepy/issue/138/include-should-take-precedence-over-is .. _issue 144: http://bitbucket.org/ned/coveragepy/issue/144/failure-generating-html-output-for Version 3.5 --- 29 June 2011 ---------------------------- HTML reporting: - 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. - 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. Running Python files - 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 detail: the current directory inserted into ``sys.path`` was relative rather than absolute. This is now fixed. - 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. - Coverage.py can now be run directly from a working tree by specifying the directory name to python: ``python coverage_py_working_dir run ...``. Thanks, Brett Cannon. - A little bit of Jython support: `coverage run` can now measure Jython execution by adapting when $py.class files are traced. Thanks, Adi Roiban. Reporting - 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 ``--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`_. - Syntax errors in supposed Python files can now be ignored during reporting with the ``-i`` switch just like other source errors. Closes `issue 115`_. .. _issue 93: http://bitbucket.org/ned/coveragepy/issue/93/copying-a-mock-object-breaks-coverage .. _issue 95: https://bitbucket.org/ned/coveragepy/issue/95/run-subcommand-should-take-a-module-name .. _issue 115: https://bitbucket.org/ned/coveragepy/issue/115/fail-gracefully-when-reporting-on-file .. _issue 121: https://bitbucket.org/ned/coveragepy/issue/121/filename-patterns-are-applied-stupidly .. _issue 123: https://bitbucket.org/ned/coveragepy/issue/123/pyeval_settrace-used-in-way-that-breaks .. _issue 125: https://bitbucket.org/ned/coveragepy/issue/125/coverage-removes-decoratortoolss-tracing Version 3.4 --- 19 September 2010 --------------------------------- Controlling source: - BACKWARD INCOMPATIBILITY: the ``--omit`` and ``--include`` switches now take file patterns rather than file prefixes, closing `issue 34`_ and `issue 36`_. - BACKWARD INCOMPATIBILITY: the `omit_prefixes` argument is gone throughout coverage.py, replaced with `omit`, a list of filename patterns suitable for `fnmatch`. 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. The run command also 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. - 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. Reporting: - Completely unexecuted files can now be included in coverage results, reported as 0% covered. This only happens if the --source option is specified, since coverage.py needs guidance about where to look for source files. - 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. - Coverage percentages are now displayed uniformly across reporting methods. Previously, different reports could round percentages differently. Also, percentages are only reported as 0% or 100% if they are truly 0 or 100, and are rounded otherwise. Fixes `issue 41`_ and `issue 70`_. - The XML report output now properly includes a percentage for branch coverage, fixing `issue 65`_ and `issue 81`_, and the report is sorted by package name, fixing `issue 88`_. - The XML report is now sorted by package name, fixing `issue 88`_. - The precision of reported coverage percentages can be set with the ``[report] precision`` config file setting. Completes `issue 16`_. - 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. Execution and measurement: - 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. - Doctest text files are no longer recorded in the coverage data, since they can't be reported anyway. Fixes `issue 52`_ and `issue 61`_. - Threads derived from ``threading.Thread`` with an overridden `run` method would report no coverage for the `run` method. This is now fixed, closing `issue 85`_. - Programs that exited with ``sys.exit()`` with no argument weren't handled properly, producing a coverage.py stack trace. This is now fixed. - 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`_. - 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. - Coverage can now be run as a module: ``python -m coverage``. Thanks, Brett Cannon. .. _issue 1: http://bitbucket.org/ned/coveragepy/issue/1/empty-__init__py-files-are-reported-as-1-executable .. _issue 16: http://bitbucket.org/ned/coveragepy/issue/16/allow-configuration-of-accuracy-of-percentage-totals .. _issue 34: http://bitbucket.org/ned/coveragepy/issue/34/enhanced-omit-globbing-handling .. _issue 36: http://bitbucket.org/ned/coveragepy/issue/36/provide-regex-style-omit .. _issue 41: http://bitbucket.org/ned/coveragepy/issue/41/report-says-100-when-it-isnt-quite-there .. _issue 52: http://bitbucket.org/ned/coveragepy/issue/52/doctesttestfile-confuses-source-detection .. _issue 56: http://bitbucket.org/ned/coveragepy/issue/56/coveragepy-cant-trace-child-processes-of-a .. _issue 61: http://bitbucket.org/ned/coveragepy/issue/61/annotate-i-doesnt-work .. _issue 65: http://bitbucket.org/ned/coveragepy/issue/65/branch-option-not-reported-in-cobertura .. _issue 70: http://bitbucket.org/ned/coveragepy/issue/70/text-report-and-html-report-disagree-on-coverage .. _issue 81: http://bitbucket.org/ned/coveragepy/issue/81/xml-report-does-not-have-condition-coverage-attribute-for-lines-with-a .. _issue 85: http://bitbucket.org/ned/coveragepy/issue/85/threadrun-isnt-measured .. _issue 88: http://bitbucket.org/ned/coveragepy/issue/88/xml-report-lists-packages-in-random-order Version 3.3.1 --- 6 March 2010 ------------------------------ - Using ``parallel=True`` in a .coveragerc file prevented reporting, but now does not, fixing `issue 49`_. - When running your code with ``coverage run``, if you call ``sys.exit()``, coverage.py will exit with that status code, fixing `issue 50`_. .. _issue 49: http://bitbucket.org/ned/coveragepy/issue/49 .. _issue 50: http://bitbucket.org/ned/coveragepy/issue/50 Version 3.3 --- 24 February 2010 -------------------------------- - Settings are now read from a .coveragerc file. A specific file can be specified on the command line with ``--rcfile=FILE``. The name of the file can be programmatically set with the ``config_file`` argument to the coverage() constructor, or reading a config file can be disabled with ``config_file=False``. - Added coverage.process_start to enable coverage measurement when Python starts. - Parallel data file names now have a random number appended to them in addition to the machine name and process id. Also, parallel data files combined with ``coverage combine`` are deleted after they're combined, to clean up unneeded files. Fixes `issue 40`_. - Exceptions thrown from product code run with ``coverage run`` are now displayed without internal coverage.py frames, so the output is the same as when the code is run without coverage.py. - Fixed `issue 39`_ and `issue 47`_. .. _issue 39: http://bitbucket.org/ned/coveragepy/issue/39 .. _issue 40: http://bitbucket.org/ned/coveragepy/issue/40 .. _issue 47: http://bitbucket.org/ned/coveragepy/issue/47 Version 3.2 --- 5 December 2009 ------------------------------- - Branch coverage: coverage.py can tell you which branches didn't have both (or all) choices executed, even where the choice doesn't affect which lines were executed. See :ref:`branch` for more details. - The table of contents in the HTML report is now sortable: click the headers on any column. The sorting is persisted so that subsequent reports are sorted as you wish. Thanks, `Chris Adams`_. - XML reporting has file paths that let Cobertura find the source code, fixing `issue 21`_. - The ``--omit`` option now works much better than before, fixing `issue 14`_ and `issue 33`_. Thanks, Danek Duvall. - Added a ``--version`` option on the command line. - Program execution under coverage is a few percent faster. - Some exceptions reported by the command line interface have been cleaned up so that tracebacks inside coverage.py aren't shown. Fixes `issue 23`_. - Fixed some problems syntax coloring sources with line continuations and source with tabs: `issue 30`_ and `issue 31`_. .. _Chris Adams: http://improbable.org/chris/ .. _issue 21: http://bitbucket.org/ned/coveragepy/issue/21 .. _issue 23: http://bitbucket.org/ned/coveragepy/issue/23 .. _issue 14: http://bitbucket.org/ned/coveragepy/issue/14 .. _issue 30: http://bitbucket.org/ned/coveragepy/issue/30 .. _issue 31: http://bitbucket.org/ned/coveragepy/issue/31 .. _issue 33: http://bitbucket.org/ned/coveragepy/issue/33 Version 3.1 --- 4 October 2009 ------------------------------ - Python 3.1 is now supported. - Coverage.py has a new command line syntax with sub-commands. This expands the possibilities for adding features and options in the future. The old syntax is still supported. Try ``coverage help`` to see the new commands. Thanks to Ben Finney for early help. - Added an experimental ``coverage xml`` command for producing coverage reports in a Cobertura-compatible XML format. Thanks, Bill Hart. - Added the ``--timid`` option to enable a simpler slower trace function that works for DecoratorTools projects, including TurboGears. Fixed `issue 12`_ and `issue 13`_. - HTML reports now display syntax-colored Python source. - Added a ``coverage debug`` command for getting diagnostic information about the coverage.py installation. - Source code can now be read from eggs. Thanks, `Ross Lawley`_. Fixes `issue 25`_. .. _Ross Lawley: http://agileweb.org/ .. _issue 25: http://bitbucket.org/ned/coveragepy/issue/25 .. _issue 12: http://bitbucket.org/ned/coveragepy/issue/12 .. _issue 13: http://bitbucket.org/ned/coveragepy/issue/13 Version 3.0.1 --- 7 July 2009 ----------------------------- - Removed the recursion limit in the tracer function. Previously, code that ran more than 500 frames deep would crash. - Fixed a bizarre problem involving pyexpat, whereby lines following XML parser invocations could be overlooked. - On Python 2.3, coverage.py could mis-measure code with exceptions being raised. This is now fixed. - The coverage.py code itself will now not be measured by coverage.py, and no coverage modules will be mentioned in the nose ``--with-cover`` plugin. - When running source files, coverage.py now opens them in universal newline mode just like Python does. This lets it run Windows files on Mac, for example. Version 3.0 --- 13 June 2009 ---------------------------- - Coverage is now a package rather than a module. Functionality has been split into classes. - HTML reports and annotation of source files: use the new ``-b`` (browser) switch. Thanks to George Song for code, inspiration and guidance. - The trace function is implemented in C for speed. Coverage runs are now much faster. Thanks to David Christian for productive micro-sprints and other encouragement. - The minimum supported Python version is 2.3. - 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. - 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. - API changes: - 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. - coverage.annotate_file is no longer available. - Removed the undocumented cache_file argument to coverage.usecache().
