ash: [PARSER] Removed noexpand/length check on eofmark Upstream comment: Date: Sun, 11 Nov 2007 14:21:23 +0800 [PARSER] Removed noexpand/length check on eofmark On Tue, Oct 30, 2007 at 04:23:35AM +0000, Oleg Verych wrote: > > } 8<<"" > ====================== Actually this (the empty delim) only works with dash by accident. I've tried bash and pdksh and they both terminate on the first empty line which is what you would expect rather than EOF. The real Korn shell does something completely different. I've fixed this in dash to conform to bash/pdksh. > In [0] it's stated, that delimiter isn't evaluated (expanded), only > quoiting must be checked. That if() seems to be completely bogus. OK I agree. The reason it was there is because the parser would have already replaced the dollar sign by an internal representation. I've fixed it properly with this patch. Test case: cat <<- $a OK $a cat <<- "" OK echo OK Old result: dash: Syntax error: Illegal eof marker for << redirection OK echo OK New result: OK OK OK function old new delta parsefname 227 152 -75 readtoken1 2819 2651 -168 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/2 up/down: 0/-243) Total: -243 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com> 2017-07-29 23:27:28 +05:30			`OK`
