Gcovr

------------------

Breaking changes:

- This release drops support for Python 2.6. (:issue:`250`)
- PIP is the only supported installation method.
- No longer encoding-agnostic under Python 2.7.
If your source files do not use the system encoding (probably UTF-8),
you will have to specify a --source-encoding.
(:issue:`148`, :issue:`156`, :issue:`256`)
- Filters now use forward slashes as path separators, even on Windows.
(:issue:`191`, :issue:`257`)
- Filters are no longer normalized into pseudo-paths.
This could change the interpretation of filters in some edge cases.

Improvements and new features:

- Improved --help output. (:issue:`236`)
- Parse the GCC 8 gcov format. (:issue:`226`, :issue:`228`)
- New --source-encoding option, which fixes decoding under Python 3.
(:issue:`256`)
- New --gcov-ignore-parse-errors flag.
By default, gcovr will now abort upon parse errors. (:issue:`228`)
- Detect the error when gcov cannot create its output files (:issue:`243`,
:issue:`244`)
- Add -j flag to run gcov processes in parallel. (:issue:`3`, :issue:`36`,
:issue:`239`)
- The --html-details flag now implies --html. (:issue:`93`, :issue:`211`)
- The --html output can now be used without an --output filename
(:issue:`223`)
- The docs are now managed with Sphinx.
(:issue:`235`, :issue:`248`, :issue:`249`, :issue:`252`, :issue:`253`)
- New --html-title option to change the title of the HTML report.
(:issue:`261`, :issue:`263`)
- New options --html-medium-threshold and --html-high-threshold
to customize the color legend. (:issue:`261`, :issue:`264`)

Internal changes:

- Huge refactoring. (:issue:`214`, :issue:`215`, :issue:`221` :issue:`225`,
:issue:`228`, :issue:`237`, :issue:`246`)
- Various testing improvements. (:issue:`213`, :issue:`214`, :issue:`216`,
:issue:`217`, :issue:`218`, :issue:`222`, :issue:`223`, :issue:`224`,
:issue:`227`, :issue:`240`, :issue:`241`, :issue:`245`)
- HTML reports are now rendered with Jinja2 templates. (:issue:`234`)
- New contributing guide. (:issue:`253`)

----------------------

- Added --html-encoding command line option (:issue:`139`).
- Added --fail-under-line and --fail-under-branch options,
which will error under a given minimum coverage. (:issue:`173`, :issue:`116`)
- Better pathname resolution heuristics for --use-gcov-file. (:issue:`146`)
- The --root option defaults to current directory '.'.
- Improved reports for "(", ")", ";" lines.
- HTML reports show full timestamp, not just date. (:issue:`165`)
- HTML reports treat 0/0 coverage as NaN, not 100% or 0%. (:issue:`105`, :issue:`149`, :issue:`196`)
- Add support for coverage-04.dtd Cobertura XML format (:issue:`164`, :issue:`186`)
- Only Python 2.6+ is supported, with 2.7+ or 3.4+ recommended. (:issue:`195`)
- Added CI testing for Windows using Appveyor. (:issue:`189`, :issue:`200`)
- Reports use forward slashes in paths, even on Windows. (:issue:`200`)
- Fix to support filtering with absolute paths.
- Fix HTML generation with Python 3. (:issue:`168`, :issue:`182`, :issue:`163`)
- Fix --html-details under Windows. (:issue:`157`)
- Fix filters under Windows. (:issue:`158`)
- Fix verbose output when using existing gcov files (:issue:`143`, :issue:`144`)

-------------------

- Added CI testing using TravisCI
- Added more tests for out of source builds and other nested builds
- Avoid common file prefixes in HTML output (:issue:`103`)
- Added the --execlude-directories argument to exclude directories
from the search for symlinks (:issue:`87`)
- Added branches taken/not taken to HTML (:issue:`75`)
- Use --object-directory to scan for gcov data files (:issue:`72`)
- Improved logic for nested makefiles (:issue:`135`)
- Fixed unexpected semantics with --root argument (:issue:`108`)
- More careful checks for covered lines (:issue:`109`)

-----------------

- Adding a test for out of source builds
- Using the starting directory when processing gcov filenames.
(:issue:`42`)
- Making relative paths the default in html output.
- Simplify html bar with coverage is zero.
- Add option for using existing gcov files (:issue:`35`)
- Fixing --root argument processing (:issue:`27`)
- Adding logic to cover branches that are ignored (:issue:`28`)

---------------------

- Change to make the -r/--root options define the root directory
for source files.
- Fix to apply the -p option when the --html option is used.
- Adding new option, '--exclude-unreachable-branches' that
will exclude branches in certain lines from coverage report.
- Simplifying and standardizing the processing of linked files.
- Adding tests for deeply nested code, and symbolic links.
- Add support for multiple —filter options in same manner as —exclude
option.

--------------------

- Adding the '--gcov-executable' option to specify
the name/location of the gcov executable. The command line option
overrides the environment variable, which overrides the default 'gcov'.
- Adding an empty "<methods/>" block to <classes/> in the XML output: this
makes out XML compliant with the Cobertura DTD. (3951)
- Allow the GCOV environment variable to override the default 'gcov'
executable. The default is to search the PATH for 'gcov' if the GCOV
environment variable is not set. (3950)
- Adding support for LCOV-style flags for excluding certain lines from
coverage analysis. (3942)
- Setup additional logic to test with Python 2.5.
- Added the --html and --html-details options to generate HTML.
- Sort output for XML to facilitate baseline tests.
- Added error when the --object-directory option specifies a bad directory.
- Added more flexible XML testing, which can ignore XML elements
that frequently change (e.g. timestamps).
- Added the '—xml-pretty' option, which is used to
generate pretty XML output for the user manual.
- Many documentation updates
