2021-10-09libbb: better coreutils compatibility for realpathRon Yorston
Add some tests which coreutils realpath pass but BusyBox realpath fails (bar one). Adjust xmalloc_realpath_coreutils() so the tests pass: - Expand symbolic links before testing whether the last path component exists. - When the link target is a relative path canonicalize it by passing it through xmalloc_realpath_coreutils() as already happens for absolute paths. - Ignore trailing slashes when finding the last path component and correctly handle the case where the only slash is at the start of the path. This requires ignoring superfluous leading slashes. - Undo all changes to the path so error messages from the caller show the original filename. function old new delta xmalloc_realpath_coreutils 214 313 +99 Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-09-17date,touch: allow timezone offsets in datesRon Yorston
Allow ISO 8601 style dates to include a timezone offset. Like the '@' format these dates aren't relative to the user's current timezone and shouldn't be subject to DST adjustment. - The implementation uses the strptime() '%z' format specifier. This an extension which may not be available so the use of timezones is a configuration option. - The 'touch' applet has been updated to respect whether DST adjustment is required, matching 'date'. function old new delta parse_datestr 624 730 +106 static.fmt_str 106 136 +30 touch_main 388 392 +4 date_main 818 819 +1 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 4/0 up/down: 141/0) Total: 141 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2021-06-04ls: don't output any colors with TERM=dumbSören Tempel
The TERM variable is usually set to "dumb" to indicate that the terminal does not support any ANSI escape sequences. Presently, ls does not honor this variable and outputs colors anyhow which results in unreadable output, unless the user explicitly disables colors using `ls --color=never`. The rational behind this change is that ls should "just work" by default, even on dumb terminals. For this reason, this patch adds a check which additionally consults the TERM variable before printing any colors. This is analogous to the existing check for ensuring that standard output is a tty. As such, colors can still be forced with `--color=force`, even if TERM is set to dumb. function old new delta is_TERM_dumb - 40 +40 ls_main 579 598 +19 .rodata 103246 103251 +5 ------------------------------------------------------------------------------ (add/remove: 1/0 grow/shrink: 2/0 up/down: 64/0) Total: 64 bytes Signed-off-by: Sören Tempel <soeren+git@soeren-tempel.net> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2021-02-23lineedit: support empty PATH entries in tab completionRon Yorston
Zero-length path prefixes can be specified in PATH as a leading or trailing colon or two adjacent colons. POSIX says that the use of zero-length prefixes to refer to the current directory is a legacy feature. Nonetheless the shells in BusyBox respect this feature, as does 'which'. Tab-completion of executables using PATH should support this too. function old new delta complete_cmd_dir_file 934 931 -3 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-3) Total: -3 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2021-02-18libbb: fix '--help' handling in FEATURE_SH_NOFORK=yDenys Vlasenko
Most BusyBox applets respond to the '--help' option by printing a usage message. This is normally handled by busybox_main() so applet main routines don't have support for '--help'. In standalone shell mode with FEATURE_SH_NOFORK enabled nofork applets are invoked directly, bypassing busybox_main(). This results in inconsistent handling of '--help': - applets which call getopt() report "unrecognized option '--help'" and print help anyway; - realpath says "--help: No such file or directory" and doesn't print help; - usleep says "invalid number '--help'" and doesn't print help. Avoid inconsistency by checking for '--help' in run_nofork_applet(). Bug found by Ron Yorston. function old new delta show_usage_if_dash_dash_help - 70 +70 run_nofork_applet 347 362 +15 run_applet_no_and_exit 432 365 -67 ------------------------------------------------------------------------------ (add/remove: 1/0 grow/shrink: 1/1 up/down: 85/-67) Total: 18 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
