Subject: How to debug a "git merge"?
Date: Wed, 14 Mar 2018 17:56:04 +0100	[thread overview]
Message-ID: <7895279B-9FB6-471B-A8BA-53315B265A51@gmail.com> (raw)

Hi,

I am investigating a Git merge (a86dd40fe) in which an older version of 
a file won over the newer version. I try to understand why this is the 
case. I can reproduce the merge with the following commands:
$ git checkout -b test a02fa3303
$ GIT_MERGE_VERBOSITY=5 git merge --verbose c1b82995c

The merge actually generates a merge conflict but not for my
problematic file. The common ancestor of the two parents (merge base) 
is b91161554.

The merge graph is not pretty (the committers don't have a clean 
branching scheme) but I cannot spot a problem between the merge commit
and the common ancestor:
$ git log --graph --oneline a86dd40fe

Can you give me a hint how to debug this merge further? How can I 
understand why Git picked a certain version of a file in a merge?

I am using Git 2.16.2 on Linux.

Thanks,
Lars
