The storage structure might be similar to Git notes, but the stored content would be in the format of commit:file:{lines:note} or blob:{lines:note}. I think writing the comments could be straightforward, but the real challenge lies in viewing a file and identifying the historical comments associated with it. I took a rough look at git blame; it likely works by backtracking through history and applying diffs in reverse to the file to determine the commit where a specific code block disappeared, thereby identifying which commit introduced that code block. However, this code comment feature seems to require tracing all changes forward to the commit of the code block and then parsing the file notes associated with each commit. I'm not sure if this approach is feasible. > During a merge, the content would be subject to the similar processing - a > squash could combine notes. > > Once stored, a git push/fetch --notes or something like that would cause > the information to be transferred to a remote in the same way as commits do. > Of course, this depends on support for non-git core servers, so that would > be not so easy. It also would depend on things like JGit supporting it. > Yes, I think different developers might need to merge various comments, but this does sound a bit complicated. Some notes could be the user's own annotations, while others are intended to be shared with the team. Users definitely wouldn't want others to merge or delete their comments from the history. Oh, now that I think about it, it might be better if such a commenting system were independent of Git. > There is a lot to think about.
