Description

Transferring the third part of dsmiley's https://github.com/apache/solr/pull/162#issuecomment-854778916 comment here for visibility and transparency:

... `/.git-blame-ignore-revs` The current contents of that file should be wiped clean because they are all Lucene commits. We inherited it from the split.

---

I note that we also inherited https://github.com/apache/solr/blob/a827aaac2bc1cc86bf182592203ea8fc749d3318/help/git.txt#L27

git config blame.ignoreRevsFile .git-blame-ignore-revs

content i.e. nothing to be done there. https://www.git-scm.com/docs/git-config#Documentation/git-config.txt-blameignoreRevsFile has info on what the file is about, in case you (like me) haven't come across it before.

Also I double-checked via

for commit in $(grep -v '#' .git-blame-ignore-revs)
do
  git show --name-only $commit
done | grep -v ^"lucene/" | sort -u

result inspection that indeed the file contents can be wiped clean i.e. its essentially all Lucene commits.
