# Note: These tests depend on the hard-coded value of 5 as the maximum depth |
|
# we will follow recursion. We start the depth at 0 and count links, not |
|
# repositories. This means that in a chain like: |
|
# |
|
# A --> B --> C --> D --> E --> F --> G --> H |
|
# 0 1 2 3 4 5 6 |
|
# |
|
# we are OK at "G", but break at "H", even though "H" is actually the 8th |
|
# repository, not the 6th, which you might expect. Counting the links allows |
|
# N+1 repositories, and counting from 0 to 5 inclusive allows 6 links. |
|
# |
|
# Note also that we must use "--bare -l" to make the link to H. The "-l" |
|
# ensures we do not do a connectivity check, and the "--bare" makes sure |
|
# we do not try to checkout the result (which needs objects), either of |
|
# which would cause the clone to fail. |
