I think the build dir should not be relative to the BASE_DIR if the COHERENCE_CACHE_DIR is set. On the CI we'll probably set it to a global location so that builds share it and they don't have to redownload it.

There should be a default for this in code. It's hard to run it locally otherwise because you need to search through code to figure out what vars to set


if (!string.IsNullOrWhiteSpace(dropsShare))
{
var coherenceShare = Path.Combine(dropsShare, "Coherence", BUILD_BRANCH);
var latestBuild = Directory.EnumerateDirectories(coherenceShare)
.Select(d => Path.GetFileName(d))
.Where(d => { int _; return int.TryParse(d, out _); })
.OrderByDescending(d => d)
.First();
var targetDir = Path.Combine(coherenceCacheDir, latestBuild);

Log.Info("Latest Coherence build is " + latestBuild + ".");

lol brain damage

var latestBuildShare = Path.Combine(coherenceShare, latestBuild);

Log.Info("Caching Coherence build " + latestBuild + " at " + targetDir + ".");
CopyFolder(latestBuildShare, targetDir, overwrite: true);
}

{
Log.Info("Coherence build " + latestBuild + " already cached at " + targetDir + ".");

Caching the nupkgs as-is is not super nice for perf especially given the directory has close to 600 nupkgs. You should probably expand it.

Why not set this up in the CI? It's easier to remove this in case we need to not use volatile?

There should be a way to overwrite this with an env var but we should move away from configurations that don't have defaults in code because it makes it hard to reproduce builds locally.

Btw, where are this variable and the one above used?

@pranavkm We don't want those variables set unless caching Coherence was successful.

@victorhurdugaci https://github.com/aspnet/KoreBuild/blob/f693dea4c9199e63bb8ae1f544f9b39861dcd073/build/shade/_use-volatile-feed.shade As we've discussed offline, we should come up with a clearer way to go about this.
