### Index Operations for Commits and Merges

Source: https://gitpython.readthedocs.io/en/stable/tutorial.html

Utilize the index (staging area) to prepare new commits and manage merge results, including streaming data for bare repositories. This example shows adding a file, committing, performing a three-way merge, and updating branches without touching the working tree.

```python
self.assertEqual(new_branch.checkout(), cloned_repo.active_branch)  # Checking out branch adjusts the wtree.
self.assertEqual(new_branch.commit, past.commit)  # Now the past is checked out.

new_file_path = os.path.join(cloned_repo.working_tree_dir, "my-new-file")
open(new_file_path, "wb").close()  # Create new file in working tree.
cloned_repo.index.add([new_file_path])  # Add it to the index.
# Commit the changes to deviate masters history.
cloned_repo.index.commit("Added a new file in the past - for later merge")

# Prepare a merge.
master = cloned_repo.heads.master  # Right-hand side is ahead of us, in the future.
merge_base = cloned_repo.merge_base(new_branch, master)  # Allows for a three-way merge.
cloned_repo.index.merge_tree(master, base=merge_base)  # Write the merge result into index.
cloned_repo.index.commit(
    "Merged past and now into future ;)",
    parent_commits=(new_branch.commit, master.commit),
)

# Now new_branch is ahead of master, which probably should be checked out and reset softly.
# Note that all these operations didn't touch the working tree, as we managed it ourselves.
# This definitely requires you to know what you are doing! :)
assert os.path.basename(new_file_path) in new_branch.commit.tree  # New file is now in tree.
master.commit = new_branch.commit  # Let master point to most recent commit.
cloned_repo.head.reference = master  # We adjusted just the reference, not the working tree or index.
```

--------------------------------

### Working Tree Diff Example

Source: https://gitpython.readthedocs.io/en/stable/reference.html

Explains how working tree differences are represented. The working tree blob will have a null hexsha and null mode, but the path will be available. This indicates a modification compared to the index or tree.

```python
When comparing to working trees, the working tree blob will have a null hexsha as a corresponding object does not yet exist. The mode will be null as well. The path will be available, though.
If it is listed in a diff, the working tree version of the file must differ from the version in the index or tree, and hence has been modified.
```

--------------------------------

### Get a Previous Commit Tree

Initialize a repository using the pure-python GitDB object database. This is the default in GitPython 0.3 and is suitable for handling huge files but may be slower for many small objects.

```python
from git.db import GitDB
repo = Repo("path/to/repo", odbt=GitDB)
```

--------------------------------

### Access and Manage Tags

Source: https://gitpython.readthedocs.io/en/stable/tutorial.html

Demonstrates how to access existing tags, inspect the commit they point to, and how to create or delete tags using the repository object.

```python
tags = repo.tags
tagref = tags[0]
tagref.tag  # Tags may have tag objects carrying additional information
tagref.commit  # but they always point to commits.
repo.delete_tag(tagref)  # Delete or
repo.create_tag("my_tag")  # create tags using the repo for convenience.
```

--------------------------------

### Managing Daemon Export Property

Source: https://gitpython.readthedocs.io/en/stable/changes.html

Illustrates how to get and set the daemon export status for a repository. This property controls whether the repository can be exported via the Git daemon.

```python
exported = repo.daemon_export
repo.daemon_export = True
```

```

--------------------------------

### Submodule Management

Source: https://gitpython.readthedocs.io/en/stable/tutorial.html

Manipulate Git submodules, including creation, removal, and updating. This example demonstrates creating a submodule, committing its addition, removing its working tree, and then updating it.

```python
# Create a new submodule and check it out on the spot, setup to track master
# branch of `bare_repo`. As our GitPython repository has submodules already that
# point to GitHub, make sure we don't interact with them.
for sm in cloned_repo.submodules:
    assert not sm.remove().exists()  # after removal, the sm doesn't exist anymore
sm = cloned_repo.create_submodule("mysubrepo", "path/to/subrepo", url=bare_repo.git_dir, branch="master")

# .gitmodules was written and added to the index, which is now being committed.
cloned_repo.index.commit("Added submodule")
assert sm.exists() and sm.module_exists()  # This submodule is definitely available.
sm.remove(module=True, configuration=False)  # Remove the working tree.
assert sm.exists() and not sm.module_exists()  # The submodule itself is still available.

# Update all submodules, non-recursively to save time. This method is very powerful, go have a look.
cloned_repo.submodule_update(recursive=False)
assert sm.module_exists()  # The submodule's working tree was checked out by update.
```

--------------------------------

```python
fifty_first_commits = list(repo.iter_commits("master", max_count=50))
assert len(fifty_first_commits) == 50
# This will return commits 21-30 from the commit list as traversed backwards master.
ten_commits_past_twenty = list(repo.iter_commits("master", max_count=10, skip=20))
assert len(ten_commits_past_twenty) == 10
assert fifty_first_commits[20:30] == ten_commits_past_twenty
```

--------------------------------

### Get Commit Trailers as List - GitPython

Source: https://gitpython.readthedocs.io/en/stable/reference.html

Use `trailers_list` to retrieve commit trailers as a list of raw key-value tuples. This method is useful for accessing all trailer instances, including duplicates.

```python
[
    ("key1", "value1.1"),
    ("key1", "value1.2"),
    ("key2", "value 2 with inner spaces"),
]
```

--------------------------------

### Querying Submodule Information

Source: https://gitpython.readthedocs.io/en/stable/tutorial.html

```python
repo = self.rorepo
sms = repo.submodules

assert len(sms) == 1
sm = sms[0]
self.assertEqual(sm.name, "gitdb")  # GitPython has gitdb as its one and only (direct) submodule...
self.assertEqual(sm.children()[0].name, "smmap")  # ...which has smmap as its one and only submodule.

# The module is the repository referenced by the submodule.
assert sm.module_exists()  # The module is available, which doesn't have to be the case.
assert sm.module().working_tree_dir.endswith("gitdb")
# The submodule's absolute path is the module's path.
assert sm.abspath == sm.module().working_tree_dir
self.assertEqual(len(sm.hexsha), 40)  # Its sha defines the commit to check out.
assert sm.exists()  # Yes, this submodule is valid and exists.
# Read its configuration conveniently.
assert sm.config_reader().get_value("path") == sm.path
self.assertEqual(len(sm.children()), 1)  # Query the submodule hierarchy.
```

--------------------------------

### Get Repository Root Tree from Repository Object

Source: https://gitpython.readthedocs.io/en/stable/tutorial.html

```python
# This example shows the various types of allowed ref-specs.
assert repo.tree() == repo.head.commit.tree
past = repo.commit("HEAD~5")
assert repo.tree(past) == repo.tree(past.hexsha)
self.assertEqual(repo.tree("v0.8.1").type, "tree")  # Yes, you can provide any refspec - works everywhere.
```

--------------------------------

### Get Commit Trailers as Dictionary - GitPython

Source: https://gitpython.readthedocs.io/en/stable/reference.html

Use `trailers_dict` to retrieve commit trailers, mapping keys to a list of their values. This method parses trailer information similar to RFC 822 email headers.

```python
{
    "key1": ["value1.1", "value1.2"],
    "key2": ["value 2 with inner spaces"],
}
```

--------------------------------

### Creating and Merging Indices

Source: https://gitpython.readthedocs.io/en/stable/tutorial.html

Shows how to create temporary in-memory indices from existing trees or by performing a three-way merge. The resulting index can be written to a file for later inspection.

```python
from git import IndexFile

# Load a tree into a temporary index, which exists just in memory.
IndexFile.from_tree(repo, "HEAD~1")
# Merge two trees three-way into memory...
merge_index = IndexFile.from_tree(repo, "HEAD~10", "HEAD", repo.merge_base("HEAD~10", "HEAD"))
# ...and persist it.
merge_index.write(os.path.join(rw_dir, "merged_index"))
```

--------------------------------

### read
