Tweak tests so that they still work when the "git init" template did not create .git/info directory. * ab/test-without-templates: tests: don't assume a .git/info for .git/info/sparse-checkout tests: don't assume a .git/info for .git/info/exclude tests: don't assume a .git/info for .git/info/refs tests: don't assume a .git/info for .git/info/attributes tests: don't assume a .git/info for .git/info/grafts tests: don't depend on template-created .git/branches t0008: don't rely on default ".git/info/exclude"

# SANITY is about "can you correctly predict what the filesystem would

|
# directories?" A typical example of !SANITY is running the test
|
|
# suite as root, where a test may expect "chmod -r file && cat file"
|
|
# to fail because file is supposed to be unreadable after a successful
|
|
# chmod. In an environment (i.e. combination of what filesystem is
|
|
# being used and who is running the tests) that lacks SANITY, you may
|
|
# be able to delete or create a file when the containing directory
|
|
# doesn't have write permissions, or access a file even if the
|
|
# containing directory doesn't have read or execute permissions.
