while calling libdiff. It's too ugly and not worth the recursion problems when there is a malloc failure (which writes to stderr - now diverted via the buf system, which calls malloc, which causes another error message etc). We can live with the standard artificial slowdown, but reduce the time a bit and only delay when we really need to (ie: when running as a server). The usleep time could probably use some tuning, it basically needs to replace the time that it used to take to fork a large process, exec gnudiff and the time that gnudiff took before writing the initial output. This eliminates a whole mess of other hacks I was considering that changed use of xmalloc to alloca() etc. It was going too fast in the wrong direction.
This is the top level of the FreeBSD source directory. This file was last revised on: $Id: README,v 1.10 1997/02/23 09:18:39 peter Exp $ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel and the contents of /etc. Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel with config(8) is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/handbook/kernelconfig.html And in the config(8) man page. The sample kernel configuration files reside in the sys/i386/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file LINT contains entries for all possible devices, not just those commonly used, and is meant more as a general reference than an actual kernel configuration file (a kernel built from it wouldn't even run).
