grep: add proper support for pattern_list

2020-04-29T22:20:18+00:00

From POSIX.1-2008: The pattern_list's value shall consist of one or more patterns separated by characters; As such, given patterns need to be split at newline characters. Without doing so, busybox grep will interpret the newline as part of the pattern which is not in accordance with POSIX.

grep: Fix -f FILE when FILE is empty and -x provided

2020-04-29T14:01:42+00:00

Grep currently special-cased empty pattern file to be the same as pattern file with one empty line (empty pattern). That does mirror how GNU grep behaves, except when -x is provided. In that case .* pattern needs to be used instead. Signed-off-by: Gray Wolf Signed-off-by: Denys Vlasenko

xargs: restore correct behaviour of -n option

2020-04-29T13:53:51+00:00

Since commit 1ff7002b1 (xargs: fix handling of quoted arguments, closes 11441) the -n option hasn't worked properly: $ echo 1 2 3 | xargs -n 1 echo 1 2 3 $ Because state is now remembered between calls to process_stdin() it's necessary to update the state before any premature return.

xargs: fix handling of quoted arguments, closes 11441

2020-01-29T13:39:13+00:00

As reported in bug 11441 when presented with a large number of quoted arguments xargs can return 'argument line too long': seq 10000 29999 | sed -e 's/^/"/' -e 's/$/"/' | busybox xargs echo This happens because the variant of process_stdin() which handles quoted arguments doesn't preserve state between calls. If the allowed number of characters is exceeded part way through a quoted argument the next call to process_stdin() incorrectly treats the terminating quote as a starting quote, thus quoting all of the argument separators. function old new delta process_stdin 274 303 +29 xargs_main 731 745 +14 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/0 up/down: 43/0) Total: 43 bytes Signed-off-by: Ron Yorston Signed-off-by: Denys Vlasenko
