* id: code shrinkRon Yorston2024-10-091-1/+19
| | | | | | | | The bogus user/group ids we use on Windows are very limited. Make these limitations explicit in the 'id' applet. Saves 464 bytes.
* test: code shrink supplementary groupsRon Yorston2024-10-091-0/+4
| | | | | | | | Since we don't use is_in_supplementary_groups() there's no need for the cached_groupinfo structure to include the members required for its support or for them to be initialised. Saves 32 bytes.

* | win32: adjust usage for timeout and pipe_progressRon Yorston2024-10-021-2/+2
| | | | | | | | | | | | | | | | Reduce the divergence from upstream in the usage messages for timeout and pipe_progress. This only affects the source; there are no visible of functional changes.
* | cut: don't print empty lines with '-s' optionRon Yorston2024-09-231-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A command like 'cut -f1 -s' would print empty lines even though they don't contain a delimiter. Add a test to avoid this. Based on a submission to the upstream mailing list: http://lists.busybox.net/pipermail/busybox/2024-July/090834.html Adds 32 bytes in 32-bit build, saves 32 in 64-bit. (GitHub issue #459)
* | dd: add support for writing to physical drivesRon Yorston2024-08-021-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A common use of 'dd' is to copy boot images to removable media. This didn't work on Windows because opening a physical drive failed with the default flags used by 'dd'. If the output file is a physical drive remove incompatible flags. Writing to a physical drive requires elevated privileges and the drive must be offline. Adds 80 bytes. (GitHub issue #435)

| * timeout: allow fractional seconds in timeout valuesRon Yorston2024-07-131-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 'timeout' applet uses parse_duration_str() to obtain its timeout values. The default configuration enables float durations. However, the applet silently ignores fractional seconds. This results in unexpected behaviour: $ timeout 5.99 sleep 5.1; echo $? Terminated 143 When float durations are enabled ensure that any fractional seconds are taken into account. function old new delta timeout_wait 44 92 +48 timeout_main 383 365 -18 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/1 up/down: 48/-18) Total: 30 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

* | 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)

| | | | | | | | | | | | | | | | | | | | | | | | 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)
