usr.bin/make Bug fixes from FreeBSD
PatchSet 299 Date: 2002/11/08 16:59:11 Author: jmallett
o Convert some broken cases where Error is called, but we
try to continue, to Fatal errors, because the logic that
we use to try to continue is far too broken, and makes
things look and act weird, because we end up pointing
past the end of a buffer boundry into freed memory in the
caller, as we don't come close to setting the lengthPtr
to a sane value.
(This only changes failure cases which would have died
horrid deaths to explicit clean death failure cases.)
PatchSet 312 Date: 2003/04/04 04:17:14 Author: imp
o No need to check to see if we're running a version of
FreeBSD 3.0 current or newer anymore.
PatchSet 317 Date: 2003/09/07 03:16:10 Author: imp
o Keep up with minor changes to NetBSD. Consider a variable
empty when not define.
PatchSet 318 Date: 2003/09/08 09:23:29 Author: ru
o Command line variables take precedence over global
variables. Make this true in the .for loops too. The
following fragment,
FOO= foo bar
all:
.for f in ${FOO}
@echo ${f}
.endfor
when run as "make FOO=xxx" should print "xxx". (OpenBSD
had this bug fixed for some time.)
PatchSet 319 Date: 2003/09/14 13:31:33 Author: ru
- Cut out the code that caches the "." directory out of
Dir_Init() into a separate function, Dir_InitDot().
- Postpone the current and object directories detection (and
caching of the "." directory) until after all command line
arguments are parsed. This makes the -C option DTRT.
