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.
