Log Message:
Allow the bulk builds to work by adding security/audit-packages as a
BULK_PREREQ package.

This slows down the pkgsrc build on my machine by approximately 8 seconds per package. Do you really want that?

Bulk builds from scratch run for 5 days on a 3.6 GHz P4, 7 days on a
2.8 GHz P4.

Now *I* am not the one who made the changes which forced
audit-packages to be installed, or SKIP_AUDIT_PACKAGES to be defined
to "yes" before a bulk build run.

I'm sorry of not having noticed that earlier. Of course you were not involved, it had just looked to me as if. :(

Altogether, there has been far too much upheaval over the last few
days which was ill-considered, not wholly tested, and the drivers
for which are still unclear to me.

If you mean most changes from me I can tell you what the drivers to them are:

I don't have confidence in shell programs that don't run in "set -e" mode. Ususally there is no error checking at all, not to mention error handling. So whenever something unexpected happens, the programs continue to run, leading to undefined behavior. With the "set -e" mode they just die. That's why I'm changing the programs into "set -e" mode.

The other thing is that I'm still a beginner regarding bulk builds. I'm trying to completely understand how they work. But some things make understanding harder than necessary. For example variable names and file names. The BROKENFILE variable is used for two completely different purposes, yet it's only one variable. The top level BROKENFILE is called ".broken.html" by default, yet it does not contain a single HTML tag at all. Don't you find this confusing, too?

I'm trying to make the bulk build framework so consistent that it would be a pleasure for me to document it in the pkgsrc guide as a system that is well thought-out, consistent, robust, reliable, etc. It isn't yet. It just happens to work. I, however, want it to work because it is designed to work, not out of coincidence.

Some days ago I had written to Thomas in a private mail that I really don't like to document things which are awful to describe. At least not if I can change them. It's fun trying out how the various awk(1) implementations behave when fed with too much input (in the regress/tools package), as I know I cannot change them. But the bulk build framework is something I can change, and that's why I do it.
