If EV_EXIT causes an exit, use the exception mechanism to unwind redirections and local variables. This way, if the final command is a redirected command, an EXIT trap now executes without the redirections. Because of these changes, EV_EXIT can now be inherited by the body of a function, so do so. This means that a function no longer prevents a fork before an exec being skipped, such as in f() { head -1 /etc/passwd; }; echo $(f) Wrapping a single builtin in a function may still cause an otherwise unnecessary fork with command substitution, however. An exit command or -e failure still invokes the EXIT trap with the original redirections and local variables in place. Note: this depends on SHELLPROC being gone. A SHELLPROC depended on keeping the redirections and local variables and only cleaning up the state to restore them. |

$FreeBSD$ This directory tree contains tools used for the maintenance and testing of FreeBSD. There is no toplevel Makefile structure since these tools are not meant to be built as part of the standard system, though there may be individual Makefiles in some of the subdirs. Please read the README files in the subdirs for further information.
