Filter git log to show only commits with notes

Question

How can I dump a log of my commits showing only the ones with notes of a given namespace?

Commits without notes, or notes not belonging to a given namespace should be filtered out

In the text dump I do not want just the note, also the commit info.

I have played with: show refs/notes/ and I believe the solution might be there rather than with "git log". However I am still having some problems to find the right command showing also all commits.

git notes will give you the id of each note and what object it applies to. So the second column is what you want.

$ git notes

Grab that last column using cut and pass them into git show.

[ "$(git notes)" = "" ] || git notes \
| cut -d' ' -f2 \
| xargs git show

To pick a specific namespace, add a --ref=namespace to git notes.

[ "$(git notes --ref=namespace)" = "" ] || git notes --ref=namespace \
| cut -d' ' -f2 
| xargs git show

The initial test, [...], prevents a slight problem: git show will show the current checkout if passed no arguments. So if there's no notes you're going to get misleading output. With the initial test that's not a problem: if the test fails, i.e., if there's no notes, then git show won't be called.
