Also support Gitlab / Gitlab CI

[VolkerH]

Hi git-bob,

can you rewrite yourself that you use the Gitlab-API vs the Github API?
This would be useful for code that is hosted on a private, self-hosted Gitlab instance.

Hi @VolkerH,

thanks for reaching out! Unfortunately, I'm not allowed to respond to you directly.
I need approval from a person who has access.

Best,

git-bob what would be necessary to update in _github_utilities.py so that it supports gitlab instead of github?

git-bob comment

To support GitLab in _github_utilities.py, you can create a similar utility file for GitLab, say _gitlab_utilities.py, using the python-gitlab library.

Below is a minimal example of how functions could be adapted for GitLab:

import os
from gitlab import Gitlab

def get_gitlab_repository(repository, private_token):
    """
    Get the GitLab repository object.
    """
    gitlab_url = os.getenv('GITLAB_URL', 'https://gitlab.com')
    gl = Gitlab(gitlab_url, private_token=private_token)
    return gl.projects.get(repository)

def add_comment_to_issue(repository, issue, comment, private_token):
    """
    Add a comment to a specific GitLab issue.
    """
    repo = get_gitlab_repository(repository, private_token)
    issue_obj = repo.issues.get(issue)
    issue_obj.notes.create({'body': comment})

def list_issues(repository, state="opened", private_token=None):
    """
    List all GitLab issues with a defined state on a specified repository.
    """
    repo = get_gitlab_repository(repository, private_token)
    return {issue.iid: issue.title for issue in repo.issues.list(state=state)}

You will need to adjust the environment variables and additional functionality as needed.

How about the other functions in _github_utilities.py ? git-bob comment

To expand _github_utilities.py to support GitLab, you would need to adapt all functions to use GitLab's API via the python-gitlab library instead of GitHub's PyGithub library. Here's an example of how you could modify the remaining functions accordingly:

from gitlab import Gitlab

def get_conversation_on_issue(repository, issue, private_token):
    """
    Retrieve the entire conversation (title, body, and comments) of a specific GitLab issue.
    """
    repo = get_gitlab_repository(repository, private_token)
    issue_obj = repo.issues.get(issue)
    conversation = f"Issue Title: {issue_obj.title}\n\n"
    conversation += f"Issue Body:\n{issue_obj.description}\n\n"
    comments = issue_obj.notes.list()
    for comment in comments:
        conversation += f"Comment by {comment.author['username']}:\n{comment.body}\n\n"
    return conversation

def get_most_recently_commented_issue(repository, private_token):
    """
    Return the issue number of the issue in a repository with the most recent comment.
    """
    repo = get_gitlab_repository(repository, private_token)
    issues = repo.issues.list(order_by="updated_at", sort="desc")
    if not issues:
        raise ValueError("No issue found")
    return issues[0].iid

def list_repository_files(repository, private_token):
    """
    List all files in a given GitLab repository.
    """
    repo = get_gitlab_repository(repository, private_token)
    tree = repo.repository_tree()
    return [item['path'] for item in tree if item['type'] == 'blob']

def create_issue(repository, title, body, private_token):
    """
    Create a new GitLab issue.
    """
    repo = get_gitlab_repository(repository, private_token)
    issue_obj = repo.issues.create({'title': title, 'description': body})
    return issue_obj.iid

Each function calls get_gitlab_repository, similar to the GitHub version, but tailored to authenticate and fetch the project using GitLab's API. Adapt fields accordingly in issue and comment objects to match GitLab's API structure. Adjust logic as needed to handle differences between GitHub and GitLab APIs.

Comment by github-actions[bot]:

It seems that there are additional functions in _github_utilities.py that need to be adapted for GitLab. Below is an example of how those remaining functions could be transformed to use the GitLab API:

def get_most_recent_comment_on_issue(repository, issue, private_token):
    """
    Retrieve the most recent comment on a specific GitLab issue.
    """
    repo = get_gitlab_repository(repository, private_token)
    issue_obj = repo.issues.get(issue)
    comments = issue_obj.notes.list(order_by='created_at', sort='desc')

    if comments:
        comment = comments[0]
        user = comment.author['username']
        text = comment.body
    else:
        user = issue_obj.author['username']
        text = issue_obj.description

    if text is None:
        text = ""

    return user, text

def get_repository_file_contents(repository, file_paths, private_token):
    """
    Retrieve the contents of specified files from a GitLab repository.
    """
    repo = get_gitlab_repository(repository, private_token)
    file_contents = {}

    for file_path in file_paths:
        try:
            file_obj = repo.files.get(file_path=file_path, ref='main')
            file_content = file_obj.decode().decode('utf-8')
            file_contents[file_path] = file_content
        except Exception as e:
            file_contents[file_path] = f"Error accessing {file_path}: {str(e)}"

    return file_contents

def send_pull_request(repository, source_branch, target_branch, title, description, private_token):
    """
    Create a merge request from a defined branch into the target branch.
    """
    repo = get_gitlab_repository(repository, private_token)

    if len(description) > 65535:
        print("Description is too long. Truncated to 65535 characters. This was the full description:", description)
        description = description[:65535]

    mr = repo.mergerequests.create({
        'source_branch': source_branch,
        'target_branch': target_branch,
        'title': title,
        'description': description
    })

    return f"Merge Request created: {mr.web_url}"

These examples illustrate how to implement the corresponding logic using the GitLab API, making sure to account for differences in API responses between GitHub and GitLab.

[haesleinhuepf]

Ok cool. git-bob implement this in a new file _gitlab_utilities.py . Also add a new file to the tests directory which tests the functions similar to how we test the github utilities.

[haesleinhuepf]

Ok, everything above looks great!

Next question: How would you implement the following functions in _gitlab_utilities.py, similar to the functions in _github_utilities.py but so that they use the gitlab API instead of the github api.

'copy_file_in_repository'
'download_to_repository'
'rename_file_in_repository'
'delete_file_from_repository'

To implement the file manipulation functions using the GitLab API in _gitlab_utilities.py, here's how you could structure them:

from gitlab import Gitlab

def get_gitlab_repository(repository, private_token):
    gitlab_url = os.getenv('GITLAB_URL', 'https://gitlab.com')
    gl = Gitlab(gitlab_url, private_token=private_token)
    return gl.projects.get(repository)

def copy_file_in_repository(repository, branch_name, src_file_path, dest_file_path, commit_message, private_token):
    repo = get_gitlab_repository(repository, private_token)
    file_obj = repo.files.get(file_path=src_file_path, ref=branch_name)
    repo.files.create({
        'file_path': dest_file_path,
        'branch': branch_name,
        'content': file_obj.content,
        'encoding': 'base64',
        'commit_message': commit_message
    })

def download_to_repository(repository, branch_name, source_url, target_filename, private_token):
    import requests
    response = requests.get(source_url)
    if response.status_code != 200:
        raise Exception(f"Failed to download file. Status code: {response.status_code}")
    repo = get_gitlab_repository(repository, private_token)
    repo.files.create({
        'file_path': target_filename,
        'branch': branch_name,
        'content': response.content.decode('utf-8'),
        'commit_message': f"Downloaded {source_url}, saved as {target_filename}."
    })

def rename_file_in_repository(repository, branch_name, old_file_path, new_file_path, commit_message, private_token):
    repo = get_gitlab_repository(repository, private_token)
    file_obj = repo.files.get(file_path=old_file_path, ref=branch_name)
    repo.files.delete(file_path=old_file_path, branch=branch_name, commit_message=commit_message)
    repo.files.create({
        'file_path': new_file_path,
        'branch': branch_name,
        'content': file_obj.content,
        'encoding': 'base64',
        'commit_message': commit_message
    })

def delete_file_from_repository(repository, branch_name, file_path, commit_message, private_token):
    repo = get_gitlab_repository(repository, private_token)
    repo.files.delete(file_path=file_path, branch=branch_name, commit_message=commit_message)

For testing, add a new file test_gitlab_utilities.py similar to test_github_utilities.py:

def test_copy_file_in_repository():
    # Implement the test for copying files in GitLab repository

def test_download_to_repository():
    # Implement the test for downloading files to GitLab repository

def test_rename_file_in_repository():
    # Implement the test for renaming files in GitLab repository

def test_delete_file_from_repository():
    # Implement the test for deleting files from GitLab repository

This mock structure illustrates how to handle file operations using the GitLab API. Adjust based on actual implementation needs and constraints.

These implementations use the python-gitlab library to handle interactions with the GitLab API, adapting similarly to the GitHub functions provided. Adjust specifics further based on testing and additional requirements.

[haesleinhuepf]

Ok, git-bob implement this in a new file _gitlab_utilities.py , but remove the private_token from all the functions and use os.environ['GITLAB_API_KEY'] within get_gitlab_repository instead. Ensure that all functions in the newly created _gitlab_utilities.py have exactly the same signature like the functions in _github_utilities.py. Also make sure to implement all functions in _github_utilities.py . We need an identical API in _gitlab_utilities.py like in _github_utilities.py

Also do not implement any tests yet.
