kill: killing a zombie process should fail

2024-05-14T11:33:03+00:00

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 shrink

2024-04-18T08:21:46+00:00

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 timeouts

2024-04-08T12:22:30+00:00

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)

md5/shaXsum: accept uppercase hex strings

2024-04-03T12:40:21+00:00

The coreutils versions of md5sum and the like accept uppercase hex strings from checksum files specified with the '-c' option. Use a case-insensitive comparison so BusyBox does the same. (GitHub issue #394)

ls: support NO_COLOR environment variable

2024-01-30T14:15:42+00:00

If the NO_COLOR environment variable is set and is not empty 'ls' won't output ANSI colour codes. This is an alternative to the existing approach of setting 'LS_COLORS=none'. See https://no-color.org/. Costs 24-32 bytes. (GitHub issue #382)

sleep: Update doc

2023-11-07T15:59:09+00:00

4c20d9f2b removed FEATURE_FLOAT_SLEEP option, thus since then there are only two variants. Fixes: 4c20d9f2b ("extend fractional duration support to "top -d N.N" and "timeout"") Signed-off-by: Petr Vorel Signed-off-by: Denys Vlasenko

install: Fix chown resetting suid/sgid bits from chmod

2023-10-02T12:26:27+00:00

Since Linux 2.2.13, chown(2) resets the suid/gid bits for all users. This patch changes the ordering so that chmod gets called after chown. This behavior follows GNU coreutils. Signed-off-by: Nero Signed-off-by: Denys Vlasenko

sort: add support for sorting version strings

2023-10-01T06:06:19+00:00

Add an implementation of strverscmp from musl so that the 'sort -V' option works. Add '-V' to the trivial usage message. Costs 248-256 bytes. (GitHub issue #370)
