[PATCH v2 3/7] t/t2012-checkout-last: test "checkout -" after a rebase

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



  $ git checkout -

does not work as expected after a rebase.  This is because the
reflog records "checkout" made by "rebase" as its implementation
detail the same way as end-user initiated "checkout", and makes it
count as the branch that was previously checked out.

Add four failing tests documenting this bug: two for a normal rebase,
and another two for an interactive rebase.
