`locate -d <file> <pattern>` panicked (slice index underflow, exit 101) when the database file is exactly one byte: `check_db` consumes that byte with `read_exact`, then `read_until(b'\0', ...)` hits EOF and appends nothing, leaving `buf` empty. `&buf[..buf.len() - 1]` then underflows `buf.len() - 1` to `usize::MAX` and slices out of bounds. Strip the trailing nul with `strip_suffix(b"\0")` (falling back to the whole buffer when `read_until` stopped at EOF without one) instead of slicing `buf.len() - 1`. An empty buffer now yields `None` (unrecognized format), so the too-short database is skipped like any other invalid one and locate exits 1 instead of crashing. Adds a regression test.
findutils
Rust implementation of GNU findutils: xargs, find, locate and updatedb.
The goal is to be a full drop-in replacement of the original commands.
Run the GNU testsuite on rust/findutils:
bash util/build-gnu.sh
# To run a specific test:
bash util/build-gnu.sh tests/misc/help-version.sh
Comparing with GNU
Build/run with BFS
bfs is a variant of the UNIX find command that operates breadth-first rather than depth-first.
bash util/build-bfs.sh
# To run a specific test:
bash util/build-bfs.sh posix/basic
