Excluding t7817, which is added in an unrelated patch series at the time of writing, this adjusts t7[5-9]*. This trick was performed via $ (cd t && sed -i -e 's/master/main/g' -e 's/MASTER/MAIN/g' \ -e 's/Master/Main/g' -- t7[5-9]*.sh) This allows us to define `GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=main` for those tests.

test_description='test aborting in-progress merges
|
|
|
|
Set up repo with conflicting and non-conflicting branches:
|
|
|
|
There are three files foo/bar/baz, and the following graph illustrates the
|
|
content of these files in each commit:
|
|
|
|
# foo/bar/baz --- foo/bar/bazz <-- main
|
|
# \
|
|
# --- foo/barf/bazf <-- conflict_branch
|
|
# \
|
|
# --- foo/bart/baz <-- clean_branch
|
|
|
|
Next, test git merge --abort with the following variables:
|
|
- before/after successful merge (should fail when not in merge context)
|
|
- with/without conflicts
|
|
- clean/dirty index before merge
|
|
- clean/dirty worktree before merge
|
|
- dirty index before merge matches contents on remote branch
|
|
- changed/unchanged worktree after merge
|
|
- changed/unchanged index after merge
