RedHat 7.2 machine, I just built the latest Subverison 0.19 sourceball: I can't create a new repository now. 'svnadmin create' just sits forever, waiting for /dev/random to decide it has enough entropy. This is because 'svnadmin create' is trying to generate a repository UUID (apr_uuid_get()), which calls apr_generate_random_bytes(), which is opening /dev/random on this box, which is blocking forever. I haven't yet figured out why this particular libc is taking forever to gather entropy -- but regardless, no spec is being violated. Shouldn't apr_generate_random_bytes() being using /dev/urandom instead? According to thom, ./configure picks up 'random' before 'urandom', and substitutes whichever it finds first. I think this is a Bad Thing. urandom should be preferred, no? Sander says there was a long thread about this, about how people wanted "strong random", but now we're stuck with a situation where apr_uuid_get() can block indefinitely... :-(
