52 # Note: These tests depend on the hard-coded value of 5 as the maximum depth
53 # we will follow recursion. We start the depth at 0 and count links, not
54 # repositories. This means that in a chain like:
56 # A --> B --> C --> D --> E --> F --> G --> H
59 # we are OK at "G", but break at "H", even though "H" is actually the 8th
60 # repository, not the 6th, which you might expect. Counting the links allows
61 # N+1 repositories, and counting from 0 to 5 inclusive allows 6 links.
63 # Note also that we must use "--bare -l" to make the link to H. The "-l"
64 # ensures we do not do a connectivity check, and the "--bare" makes sure
65 # we do not try to checkout the result (which needs objects), either of
66 # which would cause the clone to fail.
