* ash: [PARSER] Recognise here-doc delimiters terminated by EOFDenys Vlasenko2016-10-264-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
