remote-apis PR 230 added a way where producers of Tree messages can indicate that the directories contained within are stored in topological order. The advantage of using such an ordering is that it permits instantiation of such objects onto a local file system in a streaming fashion. The same holds for lookups of individual paths. Even though Bazel currently does not gain from this, this change at least modifies Bazel's REv2 client to emit topologically sorted trees. This makes it possible for tools such as Buildbarn's bb-browser to process them more efficiently. More details: - bazelbuild/remote-apis#229 - bazelbuild/remote-apis#230 Closes #16463.
