Version 3.4b1 — 2010-08-21

• 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 file name 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.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). Fixes issue 59.
