Paul Elschot commented on LUCENE-6985:
--------------------------------------
I have some long running branches against trunk that I needed to move onto
master.
These branches regularly get trunk merged into them, so rebasing will not work.
This command sequence takes a local branch brn from trunk to master.
Except for the merge and the cherry-pick, these steps can be easily done in
gitk, normally with a right click:
git checkout brn
git merge trunk # produce a merge commit, possibly resolve any conflicts.
git tag brn.20160123 # tag the merge commit
git branch -D prefilltokenstream # delete the branch
git checkout master
git branch brn # recreate the branch starting on master
git checkout brn
git cherry-pick brn.20160123 -m 2 # add a commit with the diff to trunk as
merged above

> Reporter: Dawid Weiss

>
> Some simple guides that demonstrate basic git principles and routine tasks
> (below). The guides are here:
> https://github.com/dweiss/lucene-git-guides
> Core concepts
> 1. how to clone and setup lucene/solr git repo for local work
> 2. basic git concepts: branches, remote branches, references, staging area.
> Simple tasks:
> 1. Checkout branch X, create local branch Y, modify something, create a diff
> for Jira.
> 2. Checkout branch X, create local branch Y, modify something, catch-up with
> changes on X, create a diff for Jira.
> 3. Checkout branch X, create local branch Y, modify something, catch-up with
> changes on X, apply aggregate changes from Y on X (as a single commit).
> 4. Backport feature/ commit C from branch X to Y via cherry picking.
> More advanced:
> 1. Create a feature branch off branch X, develop the feature, then apply it
> as a series of commits to X.
> 2. Create a feature branch off branch X, develop the feature, then apply it
> as a series of commits to X and Y (different branch).
