xargs: fix handling of quoted arguments, closes 11441
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 <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
