2016-10-25ash,hush: set exit code 127 in "sh /does/not/exist" caseDenys Vlasenko
Upstream commit 1 for ash: [ERROR] Allow the originator of EXERROR to set the exit status Some errors have exit status values specified by POSIX and it is therefore desirable to be able to set the exit status at the EXERROR source rather than in main.c. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Upstream commit 2 for ash: [INPUT] Use exit status 127 when the script to run does not exist This commit makes dash exit with return code 127 instead of 2 if started as non-interactive shell with a non-existent command_file specified as argument (or a directory), as documented in http://www.opengroup.org/onlinepubs/009695399/utilities/sh.html#tag_04_128_14 The wrong exit code was reported by Clint Adams and Jari Aalto through http://bugs.debian.org/548743 http://bugs.debian.org/548687 Signed-off-by: Gerrit Pape <pape@smarden.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> NB: in fact, http://bugs.debian.org/548687 was not fixed by this: "sh /dir/" thinks that EISDIR error on read is EOF, and exits 0.

2016-10-24ash: return exit status of nofork appletsRon Yorston
The commit 'ash: eval: Return status in eval functions' changed how exit status is handled in eval functions. The case of nofork applets was missed, resulting in the incorrect status potentially being returned for nofork applets when FEATURE_SH_NOFORK is enabled.

2016-10-07ash: all blocks in function node copying must be SHELL_ALIGNedDenys Vlasenko

2016-10-02ash: undo "tokname hack"Denys Vlasenko
dash has tokendlist[] array to decide which tokens end lists. We store it as first byte of each tokname_array[i]. Switch to bit array, name it like dash (tokendlist), drop special 1st byte of tokname_array[i]. This brings us closer to dash, and shrinks the binary, because many more string aliasing opportunities are now open: function old new delta pstrcmp1 - 16 +16 readtoken1 2852 2858 +6 list 326 327 +1 pstrcmp 16 15 -1 tokname 45 42 -3 ------------------------------------------------------------------------------ (add/remove: 1/0 grow/shrink: 2/2 up/down: 23/-4) Total: 19 bytes text data bss dec hex filename 943556 916 14292 958764 ea12c busybox_old 943463 916 14292 958671 ea0cf busybox_unstripped ^^^^^^^ note this!

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.

2016-10-01ash: [ERROR] Set exitstatus in onintDenys Vlasenko
Partially backported this commit: Date: Thu, 2 Oct 2014 21:07:55 +0800 [ERROR] Set exitstatus in onint Currently the exit status when we receive SIGINT is set in evalcommand which means that it doesn't always get set. For example, if you press CTRL-C at the prompt of an interactive dash, the exit status is not set to 130 as it is in many other Bourne shells. This patch fixes this by moving the setting of the exit status into onint which also simplifies evalcommand. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> The part after "if (evalbltin(cmdentry.u.cmd, argc, argv, flags))" causes testsuite failures in signal handling, so left unchanged.

2016-10-01ash: [EVAL] Pass EV_TESTED into evalcmdDenys Vlasenko
Upstream commit: Date: Tue Aug 11 20:48:15 2009 +1000 [EVAL] Pass EV_TESTED into evalcmd This patch fixes the case where the eval command is used with set -e and as part of a construct that should not cause the shell to abort, e.g., as part of the condition of an if statement. This is achieved by propagating the EV_TESTED flag into the evalstring function through evalcmd. As this alters the prototype of evalcmd it is now invoked explicitly by evalbltin. The built-in infrastructure has been changed to accomodate this special case. In order to ensure that the EXIT trap is properly executed this patch clears evalskip in exitshell. This wasn't needed before because of the broken way evalstring worked where it always clears evalskip when called by minusc.
