And I think this should go on top. You were lucky enough that I used a die() in the original code for your condition (because I thought it was a "this could never happen, right?" condition). Had it simply returned an error, the cache-daemon would have silently failed to do anything, which would have been much more confusing for you. :)

We probably should have done this as part of Clemens' 98c2924, but I didn't think of it then (but the same reasoning applies to both patches).

Subject: [PATCH] credential-cache: report more daemon connection errors

Originally, this code remained relatively silent when we failed to connect to the cache. The idea was that it was simply a cache, and we didn't want to bother the user with temporary failures (the worst case is that we would simply ask their password again).

However, if you have a configuration failure or other problem, it is helpful for the daemon to report those problems. Git will happily ignore the failed error code, but the extra information to stderr can help the user diagnose the problem.
