* sh: Unify EXERROR and EXEXECJilles Tjoelker2018-11-091-8/+11
| | | | | | | | | | | The difference between EXERROR and EXEXEC was that EXEXEC passed along exitstatus and EXERROR set exitstatus to 2 in the handling code. By changing the places that raised EXERROR to set exitstatus to 2, the handling of EXERROR and EXEXEC becomes the same. Notes: svn path=/head/; revision=340284
* Renumber copyright clause 4Warner Losh2017-02-281-1/+1
| | | | | | | | | | | | Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point.

* sh: Fix some bugs with backquoted builtins:Jilles Tjoelker2010-01-011-2/+2
| | | | | | | | | | | | | | | - correctly handle error output in $(builtin 2>&1), clarify out1/out2 vs output/errout in the code - treat all builtins as regular builtins so errors do not abort the shell and variable assignments do not persist - respect the caller's INTOFF Some bugs still exist: - expansion errors may still abort the shell - some side effects of expansions and builtins persist Notes: svn path=/head/; revision=201366

* Fix various things about SIGINT handling:Jilles Tjoelker2009-11-221-2/+13
| | | | | | | | | | | | | | | | | | | | | * exception handlers are now run with interrupts disabled, which avoids many race conditions * fix some cases where SIGINT only aborts one command and continues the script, in particular if a SIGINT causes an EINTR error which trumped the interrupt. Example: sh -c 'echo < /some/fifo; echo This should not be printed' The fifo should not have writers. When pressing ctrl+c to abort the open, the shell used to continue with the next command. Example: sh -c '/bin/echo < /some/fifo; echo This should not be printed' Similar. Note, however, that this particular case did not and does not work in interactive mode with job control enabled.

* Do not exit on SIGINT in non-interactive shells, fixes PR 1206,Martin Cracauer1998-08-241-13/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | i.e. this makes emacs usable from system(3). Programs called from shellscripts are now required to exit with proper signal status. That means, they have to kill themself. Exiting with faked numerical exit code is not sufficient. Exit with proper signal status if script exits on signal. Make the wait builtin interruptable, both with and without traps set. Use volatile sig_atomic_t where (and only where) appropriate. (Almost) fix printing of newlines on SIGINT. Make traps setable from trap handlers. This is needed for shellscripts that catch SIGINT for cleanup work but intend to exit on it, hance have to kill themself from a trap handler. I.e. mkdep. While I'm at it, make it -Wall clean. -Wall is not enabled in Makefile, since vararg warnx() macro calls in usr.bin/printf/printf.c are not -Wall-able.

| | | | | | | | | | | | | | | | | merge of parallel duplicate work by Steve Price and myself. :-] There are some changes to the build that are my fault... mkinit.c was trying (poorly) to duplicate some of the work that make(1) is designed to do. The Makefile hackery is my fault too, the depend list was incomplete because of some explicit OBJS+= entries, so mkdep wasn't picking up their source file #includes.
