I try to keep version-specific identifying information, which is already contained in git, out of my code. This includes change logs/history in each source file because git is good at keeping that information - it is redundant in the code. However, for organizations that need to do that, I suggest using clean/smudge filters so that the code inside the repository is clean, while things like the repo name and tag get injected into the code as git puts it into the working directory. The code is then cleaned up while being staged. This removes the possibility of the conflict on these lines by removing the differing lines. You can script this using a combination of sed and git commands. My own git front end does this all the time but it is not generally applicable to all platforms (only NonStop and MVS) so I have not contributed it.

I avoid the merge problem by removing the lines that will cause conflicts from the source. You can use -Xtheirs to always choose the upstream, but I do not think that is going to give you the desired result in all cases. My suggestion is to avoid the problem. Yes, using an external tool for your clean/smudge filters is the suggestion if you must have the specific conflicting lines in your code. -Randall ^ permalink raw reply [flat|nested] 8+ messages in thread

The idea is that the merge should not even see the lines that are causing the conflict because they are not in the file. Your file should have something like the following inside: Repo: $repo$ Tag: $tag$ A smudge filter can replace the $repo$ with your repository name, and $tag$ with whatever appropriate tag is. A clean filter would remove the conflicting content so merge would never see it. If you are going to change the same line in each version just to identify that the version changed, you are always going to get conflicts. [DO NOT DO THE FOLLOWNG] It is like doing the following: Commit abc1213: Line1: This is version 1.0. Commit 3533adf: Line1: This is version 1.1. This is not how git is intended to be used, in my view. -Randall P.S. Please put your responses at the end on this mailing list. ^ permalink raw reply [flat|nested] 8+ messages in thread

When you create a custom merge driver on a specific file, do you know if It possible to apply it only on a part of the file and apply also the standard merge strategy on this file ? The purpose would be to able to identify other merge conflits if this is the case … I don’t think that is possible..
