win32: changes to signal handling

2023-05-23T09:57:56+00:00

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.

xargs: reinstate use of nofork applets

2023-04-27T06:39:00+00:00

Commit 99402ca92 (xargs: kill children when interrupted by Ctrl-C) caused all child processes to be spawned, losing the advantage of running nofork applets without spawning. Costs 64 bytes.

xargs: kill children when interrupted by Ctrl-C

2023-04-07T11:52:57+00:00

A user was running the following command in a clone of the busybox-w32 repo from a busybox-w32 shell using Git for Windows: git rev-list --all | xargs git grep main.c Using Ctrl-C to interrupt the command resulted in the familiar problem that two processes ended up competing for user input: in this case the busybox-w32 shell and the Git for Windows pager, less. Make the problem go away (in this particular case) by killing all the children of xargs when it's interrupted. This is probably a sensible thing to do for other circumstances too. Adds 64-100 bytes. (GitHub issue #306)

xargs: omit support for -o

2023-01-05T08:57:39+00:00

Upstream added the -o option to reopen stdin as /dev/tty. Since /dev/tty isn't available in Microsoft Windows -o isn't applicable.
