How do you set a config option like core.sshCommand

[WilliamStam]

hi, thanks for the lib. its awesome!

im just getting stuck with something. what's the recommended way of setting the core.sshCommand config option for a repo?

nothing i try seems to be working. based on what ive seen in the source this should work. but it doesn't actually ever set the config option in the git repo.

i need to be able to run the script over an existing repo as well and it set the sshCommand and then do a pull

please help!

import asyncio
import platform
from pathlib import Path
from logger import logging

from dulwich.errors import NotGitRepository
from dulwich import porcelain
from dulwich.repo import Repo

logger = logging.getLogger(__name__)

async def main():
    path = Path("../project").resolve()
    ssh_key = Path("./deploy_key").resolve()
    remote_url = "git@url:owner/repository.git"

    try:
        Repo.discover(path)
        repo = porcelain.open_repo(path)
    except NotGitRepository:
        repo = porcelain.init(path)

    logger.debug(f"ssh key path: {ssh_key}")
    
    # git config core.sshCommand "ssh -i W:\Project\src\deploy_key"
    repo.get_config().set("core", "sshCommand", f"ssh -i {ssh_key}") 
    
    porcelain.pull(
        repo=repo,
        remote_location=remote_url,
        refspecs="main",
    )



if __name__ == "__main__":
    if platform.system().lower() == "windows":
        asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())
    asyncio.run(main())

end result workflow:

git init
git config core.sshCommand "ssh -i W:/Project/src/deploy_key"
git pull git@url:owner/repository.git main

You probably want to get the config object, then make changes to it and finally call config.write_to_path() to write the changes to disk.

wow.. um.. thank you! cant believe it was that simple in the end!

    config = repo.get_config()
    config.set("core", "sshCommand", f"'ssh -i {ssh_key}'")
    config.write_to_path()

for anyone else seeking the answer:

import asyncio
import platform
from pathlib import Path
from logger import logging

from dulwich.errors import NotGitRepository
from dulwich import porcelain
from dulwich.repo import Repo

logger = logging.getLogger(__name__)

async def main():
    path = Path("../project").resolve()
    ssh_key = Path("./deploy_key").resolve()
    remote_url = "git@url:owner/repository.git"

    try:
        Repo.discover(path)
        repo = porcelain.open_repo(path)
    except NotGitRepository:
        repo = porcelain.init(path)

    logger.debug(f"ssh key path: {ssh_key}")
    
    config = repo.get_config()
    config.set("core", "sshCommand", f"'ssh -i {ssh_key}'")
    config.write_to_path()
    
    porcelain.pull(
        repo=repo,
        remote_location=remote_url,
        refspecs="main",
    )



if __name__ == "__main__":
    if platform.system().lower() == "windows":
        asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())
    asyncio.run(main())

just something to be mindful of. seems it keeps appending to the git config

is this expected behaviour or a bug?

[jelmer]

That looks like a bug - can you file one?

It may be possible to work around it by specifying bytestrings rather than plain strings.
