2016-10-26ash: [PARSER] Fix parsing of ${##1}Denys Vlasenko
Upstream commit: Date: Thu, 4 Oct 2007 22:15:10 +0800 [PARSER] Fix parsing of ${##1} Previously dash treated ${##1} as a length operation. This patch fixes that. Test case: set -- a echo ${##1}OK Old result: 1OK New result: OK This was a real bug in ash (but not in hush). Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

Upstream commit: Date: Thu, 1 Jan 2015 07:53:10 +1100 expand: Fixed "$@" expansion when EXP_FULL is false The commit 3c06acdac0b1ba0e0acdda513a57ee6e31385dce ([EXPAND] Split unquoted $@/$* correctly when IFS is set but empty) broke the case where $@ is in quotes and EXP_FULL is false.

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.

2015-07-13ash: remove parsebackquote flagRon Yorston
Commit 503a0b8 from git://git.kernel.org/pub/scm/utils/dash/dash.git by Herbert Xu says: >The parsebackquote flag is only used in a test where it always has the >value zero. So we can remove it altogether. The first statement is incorrect: parsebackquote is non-zero when backquotes (as opposed to $(...)) are used for command substitution. It is possible for the test to be executed with parsebackquote != 0 in that case. The test is question checks whether quotes have been closed, raising the error "unterminated quoted string" if they haven't. There seems to be no good reason to allow unclosed quotes within backquotes. Bash, hush and dash (after commit 503a0b8) all treat the following as an error: XX=`"pwd` whereas BusyBox ash doesn't. It just ignores the unclosed quote and executes pwd. So, parsebackquote should be removed but not for the reason stated. function old new delta parsebackquote 1 - -1 readtoken1 3222 3182 -40 ------------------------------------------------------------------------------ (add/remove: 0/1 grow/shrink: 0/1 up/down: 0/-41) Total: -41 bytes Signed-off-by: Ron Yorston <rmy@frippery.org> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
