* ls: allow hidden system files to be omittedRon Yorston2023-06-011-2/+14
| | | | | | | | | | | | | | | | The 'ls' applet in busybox-w32 treated files with the hidden attribute as though they had a leading '.'. Some such files also have the system attribute set. Since these aren't of much interest to most users and since several of them have long unsightly names there's some advantage in allowing them to be omitted from the listing. Implement this by omitting hidden system files if the '-a' or '-A' option is given twice. Adds 80-88 bytes (GitHub issue #328)

* | win32: changes to signal handlingRon Yorston2023-05-231-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use an exit code of the form (signal << 24) when a process exits due to a signal. This replaces the previous use of (signal + 128). This makes it easier to distinguish exit codes from signals. Allow kill(2) to handle all defined signals, not just EXIT, TERM and KILL. The kill and timeout applets now accept any defined signals. Convert certain Windows status codes Unix-style signal codes. In ash: - Exit as if with SIGINT in raise_interrupt() rather than call raise(SIGINT). The latter returns an exit code of 3. - Detect if a child process exits as if with SIGINT. If not and if the parent is an interactive top-level shell, reset pending_int. This prevents the parent from seeing an INT if the child hasn't reported it exited due to INT. (Probably due to it being an interactive shell.) Costs 132-136 bytes.
* | timeout: code shrinkRon Yorston2023-05-231-2/+6
| | | | | | | | | | | | | | | | | | In the win32 code the 'parent' variable is always zero. It's also used as the pid to be killed when the child process survives the initial kill attempt. Although this works as intended there's no need for the 'parent' variable. Saves 16 bytes.
* | yes: detect pipe fail errorRon Yorston2023-04-271-4/+5
| | | | | | | | | | | | | | | | Commit 418f43bea (yes: add explicit error check for WIN32) added a call to ferror() to detect when output to a pipe failed. Now that we check for pipe failures in the winansi code we can use that instead.
* | dd: omit direct flagRon Yorston2023-04-181-4/+19
| | | | | | | | | | | | | | | | O_DIRECT isn't supported with open(2) on Microsoft Windows. All code related to the 'direct' input/output flag can be omitted. Saves 160 bytes.

| * readlink: support --, -n alwaysEric Blake2023-04-161-17/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | POSIX will be standardizing readlink (just the -n option) and realpath (just -E and -e options): https://www.austingroupbugs.net/view.php?id=1457 Change things for readlink so that the POSIX-mandated -n and -- work even when disabling the non-standard (and partially non-working) -f when FEATURE_READLINK_FOLLOW is clear. POSIX also wants readlink to be verbose by default (if the argument is not a symlink, readlink must output a diagnostic); I did NOT address that one, because I'm waiting to see what the GNU Coreutils folks do: https://lists.gnu.org/archive/html/bug-coreutils/2023-03/msg00035.html Partial fix for https://bugs.busybox.net/show_bug.cgi?id=15466 function old new delta packed_usage 34538 34557 +19 Signed-off-by: Eric Blake <eblake@redhat.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 7fb95a2a5 (win32: try to get link count for directories) allowed stat(2) to report accurate values of st_nlink for directories. There are only a couple of places in busybox-w32 where these values are required. Disable counting of subdirectories by default and only enable it when necessary. Microsoft kindly provide directories to test edge cases like this: C:/Windows/WinSxS (contains many subdirectories) C:/Windows/WinSxS/Manifests (contains many files) Adds 84-112 bytes.
