On a case-insensitive filesystem, we should realize that "a/objects" and "A/objects" are the same path. We already use fspathcmp() to check against the main object directory, but until recently we couldn't use it for comparing against other alternates (because their paths were not NUL-terminated strings). But now we can, so let's do so. Note that we also need to adjust count-objects to load the config, so that it can see the setting of core.ignorecase (this is required by the test, but is also a general bugfix for users of count-objects).

# 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.
