shell: mktokens relative TMPDIR

2020-05-15T06:24:38+00:00

The mktokens script fails when /tmp isn't writable (e.g., when building in a sandbox with a different TMPDIR). Replace absolute references to /tmp to relative references to TMPDIR. If TMPDIR is unset or null, default to /tmp. The mkbuiltins script was already hardened to work relative to TMPDIR, also defaulting to /tmp. v2 ensures that TMPDIR is quoted. v3 adds an extra quotation that prevents extra pathname expansions.

In either case, we always have to read ahead in order to complete the parsing of the previous node. Therefore we always know whether there is more to come, except in the case where we see a newline/semicolon or similar. For the purposes of sh -c, this should be sufficient.

Copyright/licence updates and remove all traces of sys/cdefs.h

2005-10-29T01:26:30+00:00

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.

Initial import.
