The term `master` has a loaded history that serves as a constant reminder of racial injustice. The Git project has no desire to perpetuate this and already started avoiding it. The test suite uses variations of this name for branches other than the default one. Apart from t3200, where we just addressed this in the previous commit, those instances can be renamed in an automated manner because they do not require any changes outside of the test script, so let's do that. Seeing as the touched branches have very little (if anything) to do with the default branch, we choose to use a completely separate naming scheme: `topic_<number>` (it cannot be `topic-<number>` because t5515 uses the `test_oid` machinery with the term, and that machinery uses shell variables internally, whose names cannot contain dashes). This trick was performed by this (GNU) sed invocation: $ sed -i 's/master\([a-z0-9]\)/topic_\1/g' t/t*.sh Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

This test runs git rebase and tests the subtree strategy.

# There are a few bugs in the rebase with regards to the subtree strategy, and
|
|
# this test script tries to document them. First, the following commit history
|
|
# is generated (the onelines are shown, time flows from left to right):
|
|
#
|
|
# topic_1 - topic_2 - topic_3
|
|
# \
|
|
# README ---------------------- Add subproject master - topic_4 - files_subtree/topic_5
|
|
#
|
|
# Where the merge moves the files master[123].t into the subdirectory
|
|
# files_subtree/ and topic_4 as well as files_subtree/topic_5 add files to that
|
|
# directory directly.
|
|
#
|
|
# Then, in subsequent test cases, `git filter-branch` is used to distill just
|
|
# the commits that touch files_subtree/. To give it a final pre-rebase touch,
|
|
# an empty commit is added on top. The pre-rebase commit history looks like
|
|
# this:
|
|
#
|
|
# Add subproject master - topic_4 - files_subtree/topic_5 - Empty commit
|
|
#
|
|
# where the root commit adds three files: topic_1.t, topic_2.t and topic_3.t.
|
|
#
|
|
# This commit history is then rebased onto `topic_3` with the
|
|
# `-Xsubtree=files_subtree` option in three different ways:
|
|
#
|
|
# 1. using `--preserve-merges`
|
|
# 2. using `--preserve-merges` and --keep-empty
|
|
# 3. without specifying a rebase backend
