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>

2021-09-14ash: fix ignoreeof optionRon Yorston
The ignoreeof option should prevent an interactive shell from exiting on EOF. This hasn't worked in BusyBox ash since commit 727752d2d (ash: better fix for ash -c 'echo 5&' and ash -c 'sleep 5&' with testcase). Commit 3b4d04b77e (ash: input: Allow two consecutive calls to pungetc) pulled in improved support for multiple calls to pungetc from dash, thus rendering much of commit 727752d2d obsolete.
