* eval: Reset handler when entering a subshellHerbert Xu2019-03-28
| | | | | | | | | | As it is a subshell can execute code that is only meant for the parent shell when it executes a longjmp that is caught by something like evalcommand. This patch fixes it by resetting the handler when entering a subshell. Reported-by: Martijn Dekker <martijn@inlv.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* Copyright/licence updates and remove all traces of sys/cdefs.hHerbert Xu2005-10-29
| | | | | | | | | | | This change updates the BSD licence to the three-clause version since NetBSD has already done so. This makes dash GPL-compatible. It also adds Christos Zoulas (NetBSD ash maintainer) to the COPYING file. I've added "copyright by Herbert Xu" to most files. Finally all CVS IDs and inclusion of sys/cdefs.h have been removed. The latter is needed for support of klibc.
