ash: Expand here-documents in the current shell environment

2020-02-22T19:29:36+00:00

Upstream commit: Date: Sun, 11 Nov 2007 15:27:00 +0800 Expand here-documents in the current shell environment Previously we always expanded here-documents in a subshell. This is contrary to the POSIX specification and how other shells behave. What's more this slows down many expansions due to the extra fork (however, it must be said that it is possible for it speed up certain expansions by running it simultaneously with the command on two CPUs). This patch move the expansion into the current shell environment. Test case: unset a cat <<- EOF > /dev/null ${a=NOT} EOF echo ${a}BAD Old result: BAD New result: NOTBAD Signed-off-by: Denys Vlasenko

ash: expand: Ensure result is escaped in cvtnum

2020-02-21T15:30:44+00:00

Upstream commit: Date: Fri, 1 Jun 2018 18:25:29 +0800 expand: Ensure result is escaped in cvtnum The minus sign generated from arithmetic expansion is currently unquoted which causes anomalies when the result is used in where the quoting matters. This patch fixes it by explicitly calling memtodest on the result in cvtnum. Signed-off-by: Herbert Xu Signed-off-by: Denys Vlasenko

ash: eval: Fail immediately with redirections errors for simple command

2020-02-20T08:36:51+00:00

Upstream commit: Date: Sat, 19 May 2018 02:39:54 +0800 eval: Fail immediately with redirections errors for simple command Previously, dash would continue to perform variable expansions even if a redirection error occured. This patch changes it so that it fails immediately. Signed-off-by: Herbert Xu Signed-off-by: Denys Vlasenko

ash: expand: Fix trailing newlines processing in backquote expanding

2020-02-17T09:24:32+00:00

Upstream commit: Date: Mon, 29 Apr 2019 19:13:37 +0500 expand: Fix trailing newlines processing in backquote expanding According to POSIX.1-2008 we should remove newlines only at the end of the substitution. Newlines-only substitions causes dash to remove newlines before beggining of the substitution. The following code: cat <2" instead of expected "12". This patch fixes trailing newlines processing in backquote expanding. Signed-off-by: Nikolai Merinov Signed-off-by: Herbert Xu Signed-off-by: Denys Vlasenko

ash: [BUILTIN] Exit without arguments in a trap should use status outside traps

2020-02-16T18:14:45+00:00

Upstream commit: Date: Mon Oct 6 10:39:47 2014 +0800 [BUILTIN] Exit without arguments in a trap should use status outside traps POSIX now requires that exit without arguments in a trap should return the last command status prior to executing traps. This patch implements this behaviour. Signed-off-by: Herbert Xu Signed-off-by: Denys Vlasenko
