Git: merge only the changes made on the branch

by

This article advises to instead of merging two branches, you would rebase them where git would only rebase non duplicate commits. But instead of cherry-picking, you might consider just rebasing the branch: rebase –onto release B bug where release is the release branch and bug is the bug branch. You then get something like C’—D’ … Read more

When using multiple WHEN MATCHED statements, do they all execute, or does only one get executed?

by

To answer your question, yes, it will only run a single match and then break. However, if you’d like to have logic to allow for conditional matching in the update, the CASE statement is rather useful for this. Something like this as an example: MERGE INTO YourTable USING (VALUES (1, 1, NULL), (0, 0, NULL), … Read more

How to make a Git merge operation ignore identical changes made to both branches?

by

Yesterday I had similar issue after a lot of cherry-pick from (and to) a side branch where I after merged with my main branch. A lot of conflicts with identical change. I solved this with a merge strategy: git checkout main-branch merge –no-commit -s recursive -X ours side-branch you can change “ours” to “theirs”. Be … Read more

Git conflict “both deleted”

by

As stated in this answer (suggested as a duplicate) : you can see a “both deleted” when branchA has a git mv oldfile newstandard commit, and branchB has a git mv oldfile newcustom commit. In that case, when trying to merge customBranch into standardBranch, git will report a conflict on three files : both deleted: … Read more

Git – diff3 Conflict Style – Temporary merge branch

by

What you have here (with the Temporary merge branch 1 and same with 2) is due to git’s “recursive merge” method: o->branch1 = “Temporary merge branch 1”; o->branch2 = “Temporary merge branch 2”; merge_recursive(o, merged_common_ancestors, iter->item, NULL, &merged_common_ancestors); (merge-recursive.c, around line 1940). Git will do a recursive merge when the commit graph has multiple candidates … Read more

Why does git produce a merge conflict when lines next to each other are changed?

by

The reason that Git behaves like this is explained well in the answers to this question: https://softwareengineering.stackexchange.com/questions/194788/why-doesnt-git-merge-adjacent-lines-without-conflict/378258#378258 Essentially, because you need the neighboring lines to provide context to the change (you can’t just use line numbers, because something may have been added or deleted above), if the lines around it have changed you usually don’t … Read more

How do I merge two maps in STL and apply a function for conflicts?

by

I don’t know of any existing function for that, but you can roll your own from something similar to std::merge implementation to have linear complexity: template<class Map, class Merger> void merge(Map& dest, const Map& source, Merger merger) { auto it1 = dest.begin(); auto it2 = source.begin(); auto&& comp = dest.value_comp(); for (; it1 != dest.end() … Read more
