How to list all tags that contain a commit?

Question

This question is similar to How to list all tags pointing to a specific commit in git, but with one difference: I wish to search for all tags that contain a specific commit within the tree of each tag, not specifically the files marked in the tag itself (in this case, only the Makefile change has been tagged).

You can't tag a particular file - tags only point to commits. You might want to edit your question with more details of the problem that you're really trying to solve. – Barbour

Note: on Windows, make sure to use git 2.0.x (2014) if you want git tag --contains to not crash. See my answer below – Afrika

There is also git branch --contains <commit> which does the same for branches. Needed both at the same time. – Teraterai

Answer 1

git tag --contains <commit>

I've tried this. But if the tag only contains one file, I believe it only searches through that file. It won't search the tree. Also, the repository I tried it on is so large git bailed and got SIGKILL'ed. – Blindheim

Tags don't contain files. They're just markers for a commit. Given that, I don't think your objection makes sense. – Mucronate

It must not be showing me the commit because of lack of memory in that case. Do you know how I can get over this? – Blindheim

Is there any way to do this against remote tags? Similar to with branches: git branch -r --contains <commit> – Lugworm

note that this command can not be always trusted. See stackoverflow.com/questions/16304574/… – Caladium

@gatispaeglis That link is about a different question. If you want to find tags containing a commit, this is how you do it. Finding commits with an identical diff is a different thing, and not very common to need. The answer you link to would be terrible advice to give to someone who just wants to find tags containing an actual commit. – Mucronate

Answer 2

Note that you need git 2.0.x (Q3 2014) in order to list all tags for a certain commit if you have a large repo

See commit cbc60b6 by Jean-Jacques Lafay (lanfeust69):

git tag --contains: avoid stack overflow

In large repos, the recursion implementation of contains(commit, commit_list) may result in a stack overflow. Replace the recursion with a loop to fix it.

This problem is more apparent on Windows than on Linux, where the stack is more limited by default.

No pun intended? ;-) – Damal

@Damal Well... not an intentional one, at least. – Afrika
