StGit 0.20 released

Thanks again to Peter Grayson, a new StGit release is available.

Features:

• stg patches -d can now output colored diffs.
• stg publish --overwrite allows branch to be overwritten instead of creating new commits.
• stg log --clear deletes the stack’s log history. Use with caution.
• Fish shell completions for stg.
• Zsh completions for stg.
• Branch protection metadata now captured in config instead of .git/patches/protect file. This updates StGit’s metadata format from v2 to v3.
• stg mail --domain option overrides the host’s domain in the message ID.

Bug fixes:

• stg show detects conflicting --applied and --unapplied options.
• stg show --stat now shows commit headers.
• stg patches --diff now shows proper diff instead of b'...' repr of diff.
• stg diff --range detects some invalid values (e.g. -r ..).
• stg diff no longer shows binary diffs by default. Use -O--binary or add --binary to stgit.diff-opts in config.
• Date parsing is now more portable, only use platform specific date as last parsing option. Affects, e.g., stg refresh --authdate.
• Repaired search path for templates to avoid looking in Python site-packages directory.
• Ensure stdout and stderr are flushed. Rarely affected stg diff.
• stg repair will now fail if extra command line arguments are provided.
• Bash completions are now generated in a reproducible manner.
• stg edit --diff on an empty patch no longer crashes.
• Diagnostic output is now routed to stderr instead of stdout. Diagnostic output is also now sent to stderr unconditionally, i.e. no more isatty() test (#35).
• stg pick no longer fails when picked commit has empty message (#39).
• stg rebase no longer crashes when there are conflicts (#34).
• stg pick no longer crashes if --name is not provided when picking a regular commit object.

Code quality:

• Converted to “new” lib infrastructure: show, patches, diff, pick, pull, rebase, and fold.
• Improved test coverage for: branch, diff, pick, sync,
• New tests for: files, patches, fold, series
• Portable use of iconv, sort, and sed in tests.
• Linting using flake8 and isort.
• All Python code now conforms to PEP-8.
• Updated test infrastructure from git 2.20.
• Parallel tests with coverage (make -j4 coverage) now works.
• Documentation build is not included in code coverage.
• Repaired log end messages when using STGIT_SUBPROCESS_LOG=debug.
• Renamed “dunder” instance attributes to improve debugging.
• Fail faster when patch name has slash (‘/’) (#24).
