* | kill: killing a zombie process should failRon Yorston2024-05-141-7/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A process which has exited may still have its process handle held open by its children. Such a process doesn't appear in the process table. It is thus similar to a zombie process in UNIX. Using kill(1) to interact with such a process was seen to succeed, contrary to expectation. The code for "ordinary" signals in kill(2) did check if the process was still active but didn't treat an attempt to kill an inactive process as an error. Furthermore, sending SIGKILL or the fake signal 0 to a process didn't even check if the process was still active. Rearrange the implementation of kill(2) so that an attempt to signal an inactive process is treated as an error. This also consolidates handling of SIGKILL and signal 0 with "ordinary" signals. Saves 96 bytes. (GitHub issue #416)
* | yes: code shrinkRon Yorston2024-04-181-5/+0
| | | | | | | | | | | | | | | | | | Now that putchar() is implemented using winansi_fputc() it isn't necessary to perform an explicit substitution in 'yes'. This was previously done so 'yes' could check for a broken pipe. Saves 16-32 bytes.
* | timeout: fix handling of timeoutsRon Yorston2024-04-081-12/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 'timeout' applet, by default, accepted fractional seconds but ignored the fraction. Moreover, in busybox-w32, even the integer part was incorrectly handled. Rewrite the (Windows) code to fix both problems. A patch has also been submitted to fix upstream. If that is accepted the Windows port will need to be updated to match. Saves 8-16 bytes. (GitHub issue #400)

| | | | | | | | | | | | | | | | | | | | When using 'ls -L' to list the target of a symlink (or equivalent) we must first check whether the link itself is hidden and thus subject to special treatment by the '-a' or '-A' options. Adds 80 bytes. (GitHub issue #331)
* | 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.

| | | | | | | | | | | | | | | | 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.
