Differences From Artifact [4021fb1aeb]:

• File auto.def — part of check-in [b0dc279205] at 2022-07-26 16:05:13 on branch trunk — auto.def: --with-zlib=tree now fails if compat/zlib is not configured and built in advance, resolving the curious problem that the downstream test for openssl fails if libz is not built. Problem discovered by Daniel D. and reported in /chat. (user: stephan size: 28477)

To Artifact [8396c043cf]:

• File auto.def — part of check-in [f938438380] at 2022-08-15 22:02:20 on branch trunk — Changed several of the Docker environment variables to build arguments so the user an override them at build time rather than container creation time, and documented them in build.wiki. Using this new mechanism to pull the Fossil source tarball in such a way that we can use the Docker artifact cache without getting stale builds. You can now pass one of the new build args to force the old behavior if you want it. This required generating Dockerfile from Dockerfile.in at configure time, to inject the current Fossil checkin ID. (This busts the Docker cache when the source tree changes.) (user: wyoung size: 28781)
