* sed: do not ignore 'g' modifier when match starts with ^Dominique Martinet2021-12-251-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is perfectly valid to start a regex with ^ and have other patterns with \| that can match more than once, e.g. the following example should print ca, as illustrated with gnu sed: $ echo 'abca' | sed -e 's/^a\|b//g' ca busybox before patch: $ echo 'abca' | busybox sed -e 's/^a\|b//g' bca busybox after patch: $ echo 'abca' | ./busybox sed -e 's/^a\|b//g' ca regcomp handles ^ perfectly well as illustrated with the second 'a' that did not match in the example, we ca leave the non-repeating to it if appropriate. The check had been added before using regcomp and was required at the time (f36635cec6da) but no longer makes sense now.

* printf: allow 0 as a flag and allow multiple flagsRon Yorston2021-12-171-0/+10
| | | | | | | | | | | | | | | | | | | | | | The '%' character in a format specification may be followed by one or more flags from the list "+- #0". BusyBox printf didn't support the '0' flag or allow multiple flags to be provided. As a result the formats '%0*d' and '%0 d' were considered to be invalid. The lack of support for '0' was pointed out by Andrew Snyder on the musl mailing list: https://www.openwall.com/lists/musl/2021/12/14/2 function old new delta printf_main 860 891 +31 .rodata 99281 99282 +1 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/0 up/down: 32/0) Total: 32 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

* libbb: better coreutils compatibility for realpathRon Yorston2021-10-091-0/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* date,touch: allow timezone offsets in datesRon Yorston2021-09-171-0/+32
| | | | | | | | | | | | | | | | | | | | | | | | 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>
* awk: fix printf %%Daniel Thau2021-09-052-0/+11
| | | | | | | | | | | | | | | | | A refactor of the awk printf code in e2e3802987266c98df0efdf40ad5da4b07df0113 appears to have broken the printf interpretation of two percent signs, which normally outputs only one percent sign. The patch below brings busybox awk printf behavior back into alignment with the pre-e2e380 behavior, the busybox printf util, and other common (awk and non-awk) printf implementations. function old new delta awk_printf 626 672 +46 Signed-off-by: Daniel Thau <danthau at bedrocklinux.org> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
