• Fixed 32-bit builds
• Fixed -lname on "symlinks" in Linux /proc
• Fixed -quit to take effect as soon as it's reached
• Stopped redirecting standard input from /dev/null for -ok and -okdir, as that violates POSIX

67/76 GNU find features supported.

• Implemented -mnewer (same as -newer) from BSD
• Implemented -depth N from BSD
• Implemented -sparse from FreeBSD
• Implemented the T and P suffices for -size, for BSD compatibility
• Added support for -gid NAME and -uid NAME as in BSD

Version 0.84.1

Bugfix release.

• Fixed #7 again
• Like GNU find, don't print warnings by default if standard input is not a terminal
• Redirect standard input from /dev/null for -ok and -okdir
• Skip . when -delete'ing
• Fixed -execdir when the root path has no slashes
• Fixed -execdir in /
• Support -perm +MODE for symbolic modes
• Fixed the build on FreeBSD

Version 0.84

64/76 GNU find features supported.

• Handle --
• (Untested) support for exotic file types like doors, ports, and whiteouts
• Improved robustness in the face of closed std{in,out,err}
• Fixed the build on macOS
• Implement -ignore_readdir_race, -noignore_readdir_race
• Implement -perm

0.82

62/76 GNU find features supported.

• Rework optimization levels
  • -O1
    • Simple boolean simplification
  • -O2
    • Purity-based optimizations, allowing side-effect-free tests like -name or -type to be moved or removed
  • -O3 (default):
    • Re-order tests to reduce the expected cost (TODO)
  • -O4
    • Aggressive optimizations that may have surprising effects on warning/error messages and runtime, but should not otherwise affect the results
  • -Ofast:
    • Always the highest level, currently the same as -O4
• Color files with multiple hard links correctly
• Treat -, ), and , as paths when required to by POSIX
  • ) and , are only supported before the expression begins
• Implement -D opt
• Implement -D rates
• Implement -fprint
• Implement -fprint0
• Implement BSD's -f
• Suggest fixes for typo'd arguments

• Squelch non-positional warnings for -follow
• Reduce memory footprint by as much as 64% by closing DIR*s earlier
• Speed up bfs by ~5% by using a better FD cache eviction policy
• Fix infinite recursion when evaluating ! expr
• Optimize unused pure expressions (e.g. -empty -a -false)
• Optimize double-negation (e.g. ! ! -name foo)
• Implement -D stat and -D tree
• Implement -O
