📦 Findutils 0.1.0 Release

Findutils 0.1.0 (tagged 2021-03-15) is the first tagged release of the project. It has no GitHub release page, so these notes were reconstructed from the git history up to the 0.1.0 tag.

It covers the initial implementation of find: the matcher-tree architecture, the bulk of the GNU predicates, and the test infrastructure the project still uses today. xargs did not exist yet — it arrived in 0.3.0.

Highlights

The find expression engine

• Initial implementation supporting -name, -print and a subset of -type, by @mcharsley
• Logical operators: -o/-or, -a/-and, !, parentheses, and comma lists
• -depth, -maxdepth, -mindepth and depth-first traversal
• -prune
• Directory walking switched to the walkdir crate

Predicates

• -size by @mcharsley
• -newer, -ctime, -atime, -mtime by @mcharsley
• -exec and -execdir by @mcharsley, plus a fix for -execdir on the root directory
• -perm by @mcharsley
• -type: added l, b, c, p and s by @ilius
• -delete by @Arcterus, extended to all file types and made to skip the current directory; tests and fixes by @dahc

Correctness fixes

• -help was matched too aggressively
• A lone - is treated as a filename
• Double negation (! !) fixed by @Arcterus

Portability

• Windows support: path separator handling in tests, testing-commandline argument reporting, and #[cfg(unix)] gating of the permission code, by @mcharsley
• AppVeyor (Windows) and Travis CI configurations by Lei Zhang

Testing & infrastructure

• Fake-stdout dependency injection so tests can assert on exact output, and argument-parsing tests, by @mcharsley
• Integration tests for the find command by @dahc
• GitHub Actions CI workflow by @dahc
• Code coverage via Codecov and tarpaulin by @Arcterus
• Migration to the Rust 2018 edition and rustfmt formatting by @Arcterus
• Various clippy fixes, including clippy::borrowed_box and clippy::unnecessary_wraps on process_dir, by @ilius
