Carefully excluding t5310, which is developed independently of the current patch series at the time of writing, we now use `main` as default branch in t5[0-4]*. This trick was performed via $ (cd t && sed -i -e 's/master/main/g' -e 's/MASTER/MAIN/g' \ -e 's/Master/Main/g' -- t5[0-4]*.sh && git checkout HEAD -- t5310\*) This allows us to define `GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=main` for those tests.

test_description='
|
|
Test pruning of repositories with minor corruptions. The goal
|
|
here is that we should always be erring on the side of safety. So
|
|
if we see, for example, a ref with a bogus name, it is OK either to
|
|
bail out or to proceed using it as a reachable tip, but it is _not_
|
|
OK to proceed as if it did not exist. Otherwise we might silently
|
|
delete objects that cannot be recovered.
