xargs: clarify -x and -t help text

The previous text implied -x only interacts with -L/-n and used imprecise phrasing. The new text mirrors the POSIX spec: terminate when a constructed command line would exceed the size limit rather than reducing the argument count. Clarify that -t prints each command to stderr, rather than just "be verbose".

weili	a70f5ccd7c	find: -ls: don't panic on an unmapped owner uid/gid `find <file> -ls` panicked (exit 101) when the file's owning uid (or gid) had no `/etc/passwd` (`/etc/group`) entry: it resolved the name with `User::from_uid(...).unwrap().unwrap()`, and the inner unwrap aborts on the `Ok(None)` that an unmapped id returns. Unmapped owners are routine (extracted archives, NFS, deleted accounts, container images). Resolve the uid/gid via `uucore::entries::uid2usr`/`gid2grp`, falling back to the numeric id when there is no entry, matching GNU find (which prints the number). These helpers already serialize the non-thread-safe getpwuid/getgrgid behind a mutex, so reuse them rather than reimplementing the lookup. Add a -ls integration test that chowns a file to an unmapped id and checks the numeric fallback; it skips when the process lacks the privilege to do so.	2026-06-10 07:45:53 +02:00

Sylvestre Ledru	c100ac226f	build: support compiling for non-Unix targets such as wasm The platform-specific code was split into cfg(unix)/cfg(windows) arms, so wasm32 targets (which are neither) failed to compile. Widen the generic Windows stubs to cfg(not(unix)) and make the -ls printer and xargs size limiters fall back to portable APIs when no platform-specific one exists.	2026-06-10 07:45:04 +02:00

weili	001966f326	find: -name: don't panic on a malformed POSIX bracket class A `-name` glob with a `[.`/`[=`/`[:` introducer whose closing delimiter is missing — only a lone `]` (or the delimiter) before a multibyte char, e.g. `'[[:]é'` — panicked (exit 101). `extract_bracket_expr` searched for either the delimiter or `]` and then added a blind `+ 2`, which overshot into the following character and sliced off a UTF-8 boundary. Search for the actual two-byte closing sequence `<delim>]` instead. A valid class (`[:alpha:]`) is unchanged; a malformed one returns None, so the caller treats `[` literally and accepts the pattern like GNU find (exit 0). Reachable via -name/-iname/-path/-ipath/-lname/-ilname. Adds a regression test.	2026-06-09 22:41:13 +02:00
