Partial pull from git bundle

Question

I'm trying to pull a subset of a git bundle into a repo.

Setup

Starting with this repo.

R1: A --> B --> C --> D --> E --> F

I've created these git bundles

# git bundle create B1 C..E
# git bundle create B1 B..F

B1:       C --> D --> E
B2: B --> C --> D --> E --> F

I've created a shallow clone, depth 1, from C

# git clone --depth 1 file:///R1 R2
R2: C

Pulling bundles

From R2 I can pull from B1 to get:

# git pull B1 main
R2: C --> D --> E

But when I'm trying to pull from B2 I get this error message

# git pull B2 main
error: Repository lacks these prerequisite commits:
error: B

Which is true, R2 does not have commit B.

Is there a way to have it ignore B and only fill up from C and get this?:

R2: C --> D --> E --> F

Answer 1

Create one bundle for each commit. Here we move the branch "main" so that each bundle have the same branch to pull from.

#B3: A --> B
git branch -f main B
git bundle create ../B3 A..main
#B4: B --> C
git branch -f main C
git bundle create ../B4 B..main
#B5: C --> D
git branch -f main D
git bundle create ../B5 C..main
#B6: D --> E
git branch -f main E
git bundle create ../B6 D..main
#B7: E --> F
git branch -f main F
git bundle create ../B7 E..F

Then pull from them in order.

git pull B3 main
git pull B4 main
git pull B5 main
git pull B6 main
git pull B7 main

You can skip pulling B3 (A-->B) and B4 (B-->C) since they will fail anyway.
