Hello, I came across a change of behavior with Git version 2.15 and later where the fast-export command would omit the merge commits. The same use case works correctly with Git version 2.14 and older. Here is the detail of the use case: 0> git --version git version 2.16.2.windows.1 1> git init Initialized empty Git repository in c:/./.git/ 2> echo 1111 >> file.txt 3> git add file.txt 4> git commit -m "first commit" [master (root-commit) 711d4d5] first commit 1 file changed, 1 insertion(+) create mode 100644 file.txt 5> git checkout -b test Switched to a new branch 'test' 6> echo 2222 >> file.txt 7> git add file.txt 8> git commit -m "commit on test branch" [test 76d231c] commit on test branch 1 file changed, 1 insertion(+) 9> git checkout master Switched to branch 'master' 10> echo 3333 >> file.txt 11> git add file.txt 12> git commit -m "commit on master branch" [master 61c55fd] commit on master branch 1 file changed, 1 insertion(+) 13> git merge test Auto-merging file.txt CONFLICT (content): Merge conflict in file.txt Automatic merge failed; fix conflicts and then commit the result. 14> notepad file.txt 15> git add file.txt 16> git commit -m "merged with test branch" [master 1442e0e] merged with test branch 17> git log commit 1442e0ee728c831e74550329e39d27d4188b4422 (HEAD -> master) Merge: 61c55fd 76d231c Author: isaac <...> Date: Mon Apr 16 15:08:39 2018 -0400 merged with test branch commit 61c55fdb883fc403e63c91b49bc11bdade62b3e8 Author: isaac <...> Date: Mon Apr 16 15:07:41 2018 -0400 commit on master branch commit 76d231cdb12eb84f45abdebede06a56f912613d3 (test) Author: isaac <...> Date: Mon Apr 16 15:07:07 2018 -0400 commit on test branch commit 711d4d5781df41924421f8629af040e7c91a8d2e Author: isaac <...> Date: Mon Apr 16 15:06:07 2018 -0400 first commit 18> echo :1 711d4d5781df41924421f8629af040e7c91a8d2e > git-marks 19> cat git-marks :1 711d4d5781df41924421f8629af040e7c91a8d2e 20> git fast-export --use-done-feature --import-marks=git-marks refs/heads/master -- feature done blob mark :2 data 12 1111 2222 commit refs/heads/master mark :3 author isaac <...> 1523905627 -0400 committer isaac <...> 1523905627 -0400 data 22 commit on test branch from :1 M 100644 :2 file.txt blob mark :4 data 12 1111 3333 commit refs/heads/master mark :5 author isaac <...> 1523905661 -0400 committer isaac <...> 1523905661 -0400 data 24 commit on master branch from :1 M 100644 :4 file.txt done Thanks, Isaac
