* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Upstream commit 1: Date: Mon, 6 Oct 2014 20:45:04 +0800 [EVAL] Move common skipcount logic into skiploop The functions evalloop and evalfor share the logic on checking and updating skipcount. This patch moves that into the helper function skiploop. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Upstream commit 2: Date: Mon, 6 Oct 2014 21:22:43 +0800 [BUILTIN] Allow return in loop conditional to set exit status https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=332954 When return is used in a loop conditional the exit status will be lost because we always set the exit status at the end of the loop to that of the last command executed in the body. This is counterintuitive and contrary to what most other shells do. This patch fixes this by always preserving the exit status of return when it is used in a loop conditional.
