2016-10-26ash: [PARSER] Recognise here-doc delimiters terminated by EOFDenys Vlasenko
Upstream commit 1: Date: Wed, 26 Sep 2007 17:14:16 +0800 [PARSER] Recognise here-doc delimiters terminated by EOF Previously dash required a <newline> character to be present in order for a here-document delimiter to be detected. Allowing EOF in the absence of a <newline> to play the same purpose allows some intuitive scripts to succeed. POSIX seems to be silence on this so this should be OK. Test case: eval 'cat <<- NOT test NOT' echo OK Old result: test NOTOK New result: test OK Upstream commit 2: Date: Sat, 20 Oct 2007 18:49:31 +0800 [PARSER] Fix here-doc corruption The change [PARSER] Recognise here-doc delimiters terminated by EOF introduced a regerssion whereby lines starting with eofmark but are not equal to eofmark would be corrupted. This patch fixes it. Test case: cat << _ACEOF _ASBOX _ACEOF Old result: SASBOX New result: _ASBOX Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2016-04-15ash: bash-compatible $'...' shouldn't expand in double quotesRon Yorston
Bash doesn't expand its $'...' construct in double quotes: $ echo "$'a\tb'" $'a\tb' Change BusyBox ash to do the same. This also fixes a problem with here documents where BusyBox ash gave an incorrect result for: $ cat <<EOF > '$' > EOF '$' Reported-by: Timo Teras <timo.teras@iki.fi> Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
