+Change history for Coverage.py
+------------------------------
+
+Version 3.5 --- 29 June 2011
+----------------------------
+
+- The HTML report hotkeys now behave slightly differently when the current
+ chunk isn't visible at all: a chunk on the screen will be selected,
+ instead of the old behavior of jumping to the literal next chunk.
+ The hotkeys now work in Google Chrome. Thanks, Guido van Rossum.
+
+
+Version 3.5b1 --- 5 June 2011
+-----------------------------
+
+- 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. Closes `issue 115`_.
+
+- Installation from source now succeeds on machines without a C compiler,
+ closing `issue 80`_.
+
+- 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.
+ Jython still doesn't provide the Python libraries needed to make
+ coverage reporting work, unfortunately.
+
+- Internally, files are now closed explicitly, fixing `issue 104`_. Thanks,
+ Brett Cannon.

+
+
+Version 3.4 --- 19 September 2010
+---------------------------------
+
+- The XML report is now sorted by package name, fixing `issue 88`_.
+
+- Programs that exited with ``sys.exit()`` with no argument weren't handled
+ properly, producing a coverage.py stack trace. That is now fixed.
+
+.. _issue 88: http://bitbucket.org/ned/coveragepy/issue/88/xml-report-lists-packages-in-random-order
+
+
+Version 3.4b2 --- 6 September 2010
+----------------------------------
+
+- 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.
+
+- The XML report output now properly includes a percentage for branch coverage,
+ fixing `issue 65`_ and `issue 81`_.
+
+- 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 precision of reported coverage percentages can be set with the
+ ``[report] precision`` config file setting. Completes `issue 16`_.
+
+- 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`_.

+.. _issue 85: http://bitbucket.org/ned/coveragepy/issue/85/threadrun-isnt-measured
+
+
+Version 3.4b1 --- 21 August 2010
+--------------------------------
+
+- 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.
+
+- 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 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 filename,
+ 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). Fixes `issue 59`_.
+
+.. _issue 1: http://bitbucket.org/ned/coveragepy/issue/1/empty-__init__py-files-are-reported-as-1-executable
+.. _issue 34: http://bitbucket.org/ned/coveragepy/issue/34/enhanced-omit-globbing-handling

+.. _issue 82: http://bitbucket.org/ned/coveragepy/issue/82/tokenerror-when-generating-html-report
+
+
+Version 3.3.1 --- 6 March 2010
+------------------------------
+
+- Using `parallel=True` in .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`.
+
+- Fixed a problem with nested loops having their branch possibilities
+ mischaracterized: `issue 39`_.
+
+- 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.
+
+- 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.
+
+- The `data_suffix` argument to the coverage constructor is now appended with
+ an added dot rather than simply appended, so that .coveragerc files will not
+ be confused for data files.
+
+- Python source files that don't end with a newline can now be executed, fixing
+ `issue 47`_.
+
+- Added an AUTHORS.txt file.
+
+.. _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
+-------------------------------
+
+- Added a ``--version`` option on the command line.
+
+
+Version 3.2b4 --- 1 December 2009
+---------------------------------
+
+- Branch coverage improvements:
+
+ - The XML report now includes branch information.
+
+- Click-to-sort HTML report columns are now persisted in a cookie. Viewing
+ a report will sort it first the way you last had a coverage report sorted.
+ Thanks, `Chris Adams`_.
+
+- On Python 3.x, setuptools has been replaced by `Distribute`_.
+
+.. _Distribute: http://packages.python.org/distribute/
+
+
+Version 3.2b3 --- 23 November 2009
+----------------------------------
+
+- Fixed a memory leak in the C tracer that was introduced in 3.2b1.
+
+- Branch coverage improvements:
+
+ - Branches to excluded code are ignored.
+
+- The table of contents in the HTML report is now sortable: click the headers
+ on any column. Thanks, `Chris Adams`_.
+
+.. _Chris Adams: http://improbable.org/chris/
+
+
+Version 3.2b2 --- 19 November 2009
+----------------------------------
+
+- Branch coverage improvements:
+
+ - Classes are no longer incorrectly marked as branches: `issue 32`_.
+
+ - "except" clauses with types are no longer incorrectly marked as branches:
+ `issue 35`_.
+
+- Fixed some problems syntax coloring sources with line continuations and
+ source with tabs: `issue 30`_ and `issue 31`_.
+
+- The --omit option now works much better than before, fixing `issue 14` and
+ `issue 33`_. Thanks, Danek Duvall.
+
+.. _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 32: http://bitbucket.org/ned/coveragepy/issue/32
+.. _issue 33: http://bitbucket.org/ned/coveragepy/issue/33
+.. _issue 35: http://bitbucket.org/ned/coveragepy/issue/35
+
+
+Version 3.2b1 --- 10 November 2009
+----------------------------------
+
+- Branch coverage!
+
+- XML reporting has file paths that let Cobertura find the source code.
+
+- The tracer code has changed, it's 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`_.
+
+.. _issue 23: http://bitbucket.org/ned/coveragepy/issue/23
+
+
+Version 3.1 --- 4 October 2009
+------------------------------
+
+- Source code can now be read from eggs. Thanks, Ross Lawley. Fixes
+ `issue 25`_.
+
+.. _issue 25: http://bitbucket.org/ned/coveragepy/issue/25
+
+
+Version 3.1b1 --- 27 September 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 show modules from other directories. Fixed `issue 11`_.
+
+- HTML reports now display syntax-colored Python source.
+
+- Programs that change directory will still write .coverage files in the
+ directory where execution started. Fixed `issue 24`_.
+
+- Added a "coverage debug" command for getting diagnostic information about the
+ coverage.py installation.
+
+.. _issue 11: http://bitbucket.org/ned/coveragepy/issue/11
+.. _issue 12: http://bitbucket.org/ned/coveragepy/issue/12
+.. _issue 13: http://bitbucket.org/ned/coveragepy/issue/13
+.. _issue 24: http://bitbucket.org/ned/coveragepy/issue/24
+
+
+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 `issue 9`.
+
+- Fixed a bizarre problem involving pyexpat, whereby lines following XML parser
+ invocations could be overlooked. Fixed `issue 10`.
+
+- 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 plug-in. Fixed
+ `issue 8`.
+
+- 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.
+
+.. _issue 9: http://bitbucket.org/ned/coveragepy/issue/9
+.. _issue 10: http://bitbucket.org/ned/coveragepy/issue/10
+.. _issue 8: http://bitbucket.org/ned/coveragepy/issue/8
+
+
+Version 3.0 --- 13 June 2009
+----------------------------
+
+- Fixed the way the Python library was ignored. Too much code was being
+ excluded the old way.
+
+- Tabs are now properly converted in HTML reports. Previously indentation was
+ lost. Fixed `issue 6`.
+
+- Nested modules now get a proper flat_rootname. Thanks, Christian Heimes.
+
+.. _issue 6: http://bitbucket.org/ned/coveragepy/issue/6
+
+
+Version 3.0b3 --- 16 May 2009
+-----------------------------
+
+- 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 --- 30 April 2009
+------------------------------
+
+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 --- 7 March 2009
+------------------------------
+
+Major overhaul.
+
+- Coverage is now a package rather than a module. Functionality has been split
+ into classes.
+
+- 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.
+
+- 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.
+
+- The minimum supported Python version is 2.3.
+
+
+Version 2.85 --- 14 September 2008
+----------------------------------
+
+- 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 --- 25 May 2008
+----------------------------
+
+- Open files in rU mode to avoid line ending craziness. Thanks, Edward Loper.
+
+
+Version 2.78 --- 30 September 2007
+----------------------------------
+
+- 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 --- 29 July 2007
+-----------------------------
+
+- Better packaging.
+
+
+Version 2.76 --- 23 July 2007
+-----------------------------
+
+- Now Python 2.5 is *really* fully supported: the body of the new with
+ statement is counted as executable.
+
+
+Version 2.75 --- 22 July 2007
+-----------------------------
+
+- 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 --- 21 July 2007
+----------------------------
+
+- "#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 --- 23 August 2006
+------------------------------
+
+- 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 --- 4 December 2005
+-------------------------------
+
+- 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 --- 31 December 2004
+--------------------------------
+
+- Allow for keyword arguments in the module global functions. Thanks, Allen.
+
+
+Version 2.1 --- 14 December 2004
+--------------------------------
+
+- Return 'analysis' to its original behavior and add 'analysis2'. Add a global
+ for 'annotate', and factor it, adding 'annotate_file'.
+
+
+Version 2.0 --- 12 December 2004
+--------------------------------
+
+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

+
+2001-12-06 GDR Added command-line interface and source code annotation.
+

+
+2001-12-12 GDR Added command-line help. Cache analysis so that it only needs to
+be done once when you specify -a and -r.
+
+2001-12-13 GDR Improved speed while recording. Portable between Python 1.5.2
+and 2.1.1.
+
+2002-01-03 GDR Module-level functions work correctly.
+
+2002-01-07 GDR Update sys.path when running a file with the -x option, so that
+it matches the value the program would get if it were run on its own.

+Measure, collect, and report on code coverage in Python programs.
+
+Usage:
+
+coverage -x [-p] [-L] [--timid] MODULE.py [ARG1 ARG2 ...]
+ Execute the module, passing the given command-line arguments, collecting
+ coverage data. With the -p option, include the machine name and process
+ id in the .coverage file name. With -L, measure coverage even inside the
+ Python installed library, which isn't done by default. With --timid, use a
+ simpler but slower trace method.
+
+coverage -e
+ Erase collected coverage data.
+
+coverage -c
+ Combine data from multiple coverage files (as created by -p option above)
+ and store it into a single file representing the union of the coverage.
+
+coverage -r [-m] [-i] [-o DIR,...] [FILE1 FILE2 ...]
+ Report on the statement coverage for the given files. With the -m
+ option, show line numbers of the statements that weren't executed.
+
+coverage -b -d DIR [-i] [-o DIR,...] [FILE1 FILE2 ...]
+ Create an HTML report of the coverage of the given files. Each file gets
+ its own page, with the file listing decorated to show executed, excluded,
+ and missed lines.
+
+coverage -a [-d DIR] [-i] [-o DIR,...] [FILE1 FILE2 ...]
+ Make annotated copies of the given files, marking statements that
+ are executed with > and statements that are missed with !.
+
+-d DIR
+ Write output files for -b or -a to this directory.
+
+-i Ignore errors while reporting or annotating.
+
+-o DIR,...
+ Omit reporting or annotating files when their filename path starts with
+ a directory listed in the omit list.
+ e.g. coverage -i -r -o c:\python25,lib\enthought\traits
+
+Coverage data is saved in the file .coverage by default. Set the
+COVERAGE_FILE environment variable to save it somewhere else.
