2017-07-31ash: significant overhaul of redirect saving logicDenys Vlasenko
New code is similar to what hush is doing. Make CLOSED to -1: same as dash. popredir() loses "restore" parameter: same as dash. COPYFD_RESTORE bit is no longer necessary. This change fixes this interactive bug: $ ls -l /proc/$$/fd 10>&- ash: can't set tty process group: Bad file descriptor ash: can't set tty process group: Bad file descriptor [1]+ Done(2) ls -l /proc/${\$}/fd 10>&4294967295 function old new delta unwindredir 29 27 -2 tryexec 154 152 -2 evaltree 503 501 -2 evalcommand 1369 1367 -2 cmdloop 187 185 -2 redirect 1029 1018 -11 popredir 153 123 -30 need_to_remember 36 - -36 is_hidden_fd 68 - -68 ------------------------------------------------------------------------------ (add/remove: 0/2 grow/shrink: 0/7 up/down: 0/-155) Total: -155 bytes text data bss dec hex filename 914572 485 6848 921905 e1131 busybox_old 914553 485 6848 921886 e111e busybox_unstripped Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

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.

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.
