There were no tests for either, except a brief use in t1200-tutorial. These tools are not used much these days, as most people use the merge-recursive strategy, which handles everything internally. However, they are used by the "octopus" and "resolve" strategies, as well as any custom strategies or merge scripts people have built around them. For example, together with read-tree, they are the simplest way to do a basic content-level merge without checking out the entire repository contents beforehand. This script adds a basic test of the tools to perform one content-level merge. It also shows a failure of the tools to work properly in the face of GIT_WORK_TREE. Signed-off-by: Jeff King <peff@xxxxxxxx> --- We could also exercise the more exotic "both sides added" code paths of merge-one-file. But anybody who cares about that these days is almost certainly using "read-tree --aggressive" anyway. t/t6060-merge-index.sh | 70 ++++++++++++++++++++++++++++++++++++++++++++++++ 1 files changed, 70 insertions(+), 0 deletions(-) create mode 100755 t/t6060-merge-index.sh diff --git a/t/t6060-merge-index.sh b/t/t6060-merge-index.sh new file mode 100755 index 0000000..8f8ec77 --- /dev/null +++ b/t/t6060-merge-index.sh @@ -0,0 +1,70 @@ +#!/bin/sh + +test_description='basic git merge-index / git-merge-one-file tests' +. ./test-lib.sh + +test_expect_success 'setup diverging branches' ' + for i in 1 2 3 4 5 6 7 8 9 10; do + echo $i + done >file && + git add file && + git commit -m base && + git tag base && + sed s/2/two/ <file >tmp && + mv tmp file && + git commit -a -m two && + git tag two && + git checkout -b other HEAD^ && + sed s/10/ten/ <file >tmp && + mv tmp file && + git commit -a -m ten && + git tag ten +' + +cat >expect-merged <<'EOF' +1 +two +3 +4 +5 +6 +7 +8 +9 +ten +EOF + +test_expect_success 'read-tree does not resolve content merge' ' + git read-tree -i -m base ten two && + echo file >expect && + git diff-files --name-only --diff-filter=U >unmerged && + test_cmp expect unmerged +' + +test_expect_success 'git merge-index git-merge-one-file resolves' ' + git merge-index git-merge-one-file -a && + git diff-files --name-only --diff-filter=U >unmerged && + >expect && + test_cmp expect unmerged && + test_cmp expect-merged file && + git cat-file blob :file >file-index && + test_cmp expect-merged file-index +' + +test_expect_failure 'merge-one-file respects GIT_WORK_TREE' ' + git clone . bare.git && + (cd bare.git && + mkdir work && + GIT_WORK_TREE=$PWD/work && + export GIT_WORK_TREE && + GIT_INDEX_FILE=$PWD/merge.index && + export GIT_INDEX_FILE && + git read-tree -i -m base ten two && + git merge-index git-merge-one-file -a && + git cat-file blob :file >work/file-index + ) && + test_cmp expect-merged bare.git/work/file && + test_cmp expect-merged bare.git/work/file-index +' + +test_done -- 1.7.5.rc3.17.g5e09b -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
