Hi, this is a mail mainly to remind us that there is a problem involving the new ccache support, URL escaping and system branch repos. The problem is this: When you run "morph build <system>" in a system branch and the build involves locally cloned repos with colons in the filename (e.g. "upstream:linux"), morph will attempt to create a /src/cache/ccache/upstream:linux directory and will try to bind-mount that directory into the staging area using mount --bind /src/cache/ccache/upstream:linux There are two problems with this: a) mainly, this doesn't work: the mount command will assume that "/src/cache/ccache/upstream" is a socket family or someting and will fail with a "bad address" error. b) secondly, the ccache directory name is not "unique", i.e., we are not using the same repo URL escaping mechanism as we are using for the local and remote repo caches. The way this currently works is that the LocalRepoCache is asked to create a repo from a file:// URL, it will simply use the local path. If it is asked to do the same for a non-file URL, it will cache the repo etc. The Builder classes uses this to obtain the full local path of e.g. the /src/workspace/your/system/branch/upstream:linux repo, then takes the basename and creates /src/cache/ccache/upstream:linux for ccache. A quick fix is to simply replace : with _ in Builder. A better fix would probably be to use URL escaping based on the resolved original repo URL. So not escape file:///src/workspace/your/branch/upstream:linux but resolve it's morph.repository URL and use that.
