+= How-to Commit
If you are a committer, feel free to pick any process that works for you
- so long as you are planning to commit the work yourself.
-Here is how committing and merging typically look for merging and
-pushing for tickets that follow the convention (if patch-based).
-A hypothetical CASSANDRA-12345 ticket used in the example is a cassandra-3.0
-based bug fix that requires different code for cassandra-3.3, and trunk.
-Contributor Jackie is supplying a patch for the root branch (12345-3.0.patch),
-and patches for the remaining branches (12345-3.3.patch, 12345-trunk.patch).

+Here is how committing and merging will usually look for merging and
+pushing for tickets that follow the convention (if patch-based):
+
+Hypothetical CASSANDRA-12345 ticket is a cassandra-3.0 based bug fix
+that requires different code for cassandra-3.11, cassandra-4.0, and
+trunk. Contributor Jackie supplied a patch for the root branch
+(12345-3.0.patch), and patches for the remaining branches
+(12345-3.11.patch, 12345-4.0.patch, 12345-trunk.patch).
On cassandra-3.0:::
- . `git am -3 12345-3.0.patch` (if we have a problem b/c of CHANGES.txt
- not merging anymore, we modify it ourselves, in place)
-On cassandra-3.3:::
- . `git merge cassandra-3.0 -s ours`
- . `git apply -3 12345-3.3.patch` (likely to have an issue with
- CHANGES.txt here: modify it ourselves, then `git add CHANGES.txt`)
- . `git commit -amend`
+ . `+git am -3 12345-3.0.patch+` (any problem b/c of CHANGES.txt not
+ merging anymore, fix it in place)
+ . `+ant realclean && ant jar build-test+` (rebuild to make sure code
+ compiles)
+On cassandra-3.11:::
+ . `+git merge cassandra-3.0 -s ours+`
+ . `+git apply -3 12345-3.11.patch+` (any issue with CHANGES.txt : fix
+ and [.title-ref]#git add CHANGES.txt#)
+ . `+ant realclean && ant jar build-test+` (rebuild to make sure code
+ compiles)
+ . `+git commit --amend+` (Notice this will squash the 3.11 applied
+ patch into the forward merge commit)
+On cassandra-4.0:::
+ . `+git merge cassandra-3.11 -s ours+`
+ . `+git apply -3 12345-4.0.patch+` (any issue with CHANGES.txt : fix
+ and [.title-ref]#git add CHANGES.txt#)
+ . `+ant realclean && ant jar build-test+` (rebuild to make sure code
+ compiles)
+ . `+git commit --amend+` (Notice this will squash the 4.0 applied
+ patch into the forward merge commit)
On trunk:::
- . `git merge cassandra-3.3 -s ours`
- . `git apply -3 12345-trunk.patch` (likely to have an issue with
- CHANGES.txt here: modify it ourselves, then `git add CHANGES.txt`)

+
+== Git branch based Contribution
Same scenario, but a branch-based contribution:
On cassandra-3.0:::
- . `git cherry-pick <sha-of-3.0-commit>` (if we have a problem b/c of
- CHANGES.txt not merging anymore, we modify it ourselves, in place)
-On cassandra-3.3:::
- . `git merge cassandra-3.0 -s ours`
- . `git format-patch -1 <sha-of-3.3-commit>`
- . `git apply -3 <sha-of-3.3-commit>.patch` (likely to have an issue
- with CHANGES.txt here: modify it ourselves, then `git add CHANGES.txt`)
- . `git commit -amend`
+ . `+git cherry-pick <sha-of-3.0-commit>+` (any problem b/c of
+ CHANGES.txt not merging anymore, fix it in place)
+ . `+ant realclean && ant jar build-test+` (rebuild to make sure code
+ compiles)
+On cassandra-3.11:::
+ . `+git merge cassandra-3.0 -s ours+`
+ . `+git format-patch -1 <sha-of-3.11-commit>+` (alternative to
+ format-patch and apply is [.title-ref]#cherry-pick -n#)
+ . `+git apply -3 <sha-of-3.11-commit>.patch+` (any issue with
+ CHANGES.txt : fix and [.title-ref]#git add CHANGES.txt#)
+ . `+ant realclean && ant jar build-test+` (rebuild to make sure code
+ compiles)
+ . `+git commit --amend+` (Notice this will squash the 3.11 applied
+ patch into the forward merge commit)
+On cassandra-4.0:::
+ . `+git merge cassandra-3.11 -s ours+`
+ . `+git format-patch -1 <sha-of-4.0-commit>+` (alternative to
+ format-patch and apply is [.title-ref]#cherry-pick -n#)

+ . `+ant realclean && ant jar build-test+` (rebuild to make sure code
+ compiles)
+ . `+git commit --amend+` (Notice this will squash the 4.0 applied
+ patch into the forward merge commit)
On trunk:::
- . `git merge cassandra-3.3 -s ours`
- . `git format-patch -1 <sha-of-trunk-commit>`
- . `git apply -3 <sha-of-trunk-commit>.patch` (likely to have an issue

+ . `+ant realclean && ant jar build-test+` (rebuild to make sure code
+ compiles)
+ . `+git commit --amend+` (Notice this will squash the trunk applied
+ patch into the forward merge commit)
On any branch:::
- . `git push origin cassandra-3.0 cassandra-3.3 trunk -atomic`
+ . `+git push origin cassandra-3.0 cassandra-3.11 cassandra-4.0 trunk
--atomic -n+`
+ (dryrun check)
+ . `+git push origin cassandra-3.0 cassandra-3.11 cassandra-4.0 trunk
--atomic+`
+
+== Contributions only for release branches
+
+If the patch is for an older branch, and doesn't impact later branches
+(such as trunk), we still need to merge up.
+
+On cassandra-3.0:::
+ . `+git cherry-pick <sha-of-3.0-commit>+` (any problem b/c of
+ CHANGES.txt not merging anymore, fix it in place)
+ . `+ant realclean && ant jar build-test+` (rebuild to make sure code

+On cassandra-3.11:::
+ . `+git merge cassandra-3.0 -s ours+`
+ . `+ant realclean && ant jar build-test+` (rebuild to make sure code

+On cassandra-4.0:::

-If a conflict is detected, you can either resolve it manually or invoke `git

-The `-atomic` flag to `git push` does the obvious thing: pushes all or

you won’t push half the branches, blocking other committers’ progress
