Where in git lock?

Question

git

Hello. How can I lock a file in git so that other developers cannot edit it?
Example: there is a picture that needs to be changed, but it is not specifically indicated who will do it. Two developers will start editing it at the same time, and as a result, only someone's version will have to be applied (the other's version is replaced).
In SVN and tfs it is possible to lock a file for the duration of the change. How to do it in git? If this is not the case, then why and how to act in such a situation?
Thank you.

Answer 1

there's no such thing.
if you write a merge tool for your binary data, it will be :)
this is all because git, unlike svn, is a decentralized version control system. where specifically to lochit something? Vasya or Petya?
