<!-- Answer -->
To resolve the error "subtask Clone Git Repo ended unexpectedly Wraps: (2)
git exit error Error types: (1) *hintdetail.withDetail (2) *errors.errorString"
and successfully add your repository, follow these steps:
1. **Check Proxy Settings**: Ensure that the proxy settings are correctly
configured if you are using a proxy. Verify that the `taskData.Options.Proxy`
is set correctly.
2. **Verify Private Key Handling**: If you are using SSH with a private key,
ensure that the private key and passphrase are correctly handled. The code
creates a temporary file for the private key and sets the appropriate
permissions. Ensure that this process is not failing.
3. **Check Git Command Execution**: Ensure that the `execGitCommand` and
`execGitCommandIn` functions are correctly handling the git commands and their
environment. Verify that the commands are correctly formed and that the
environment variables are set properly.
4. **Handle Shallow Clone Issues**: Ensure that the `--depth=1` and
`--shallow-since` options are used correctly if you are performing a shallow
clone.
Additionally, ensure that the `CloneGitRepo` function in the
`CloneGitRepoMeta` subtask is correctly implemented. Here is the relevant part
of the code:
```go
func CloneGitRepo(subTaskCtx plugin.SubTaskContext) errors.Error {
taskData, ok := subTaskCtx.GetData().(*parser.GitExtractorTaskData)
if (!ok) {
panic("git repo reference not found on context")
}
op := taskData.Options
storage := store.NewDatabase(subTaskCtx, op.RepoId)
var err errors.Error
logger := subTaskCtx.GetLogger()
// temporary dir for cloning
localDir, e := os.MkdirTemp("", "gitextractor")
if e != nil {
return errors.Convert(e)
}
// clone repo
repoCloner := parser.NewGitcliCloner(subTaskCtx)
err = repoCloner.CloneRepo(subTaskCtx, localDir)
if err != nil {
if errors.Is(err, parser.ErrNoData) {
taskData.SkipAllSubtasks = true
return nil
}
return err
}
if repoCloner.IsIncremental() {
storage.SetIncrementalMode(repoCloner.IsIncremental())
}
// We have done comparison experiments for git2go and go-git, and the
results show that git2go has better performance.
var repoCollector parser.RepoCollector
if *taskData.Options.UseGoGit {
repoCollector, err = parser.NewGogitRepoCollector(localDir,
op.RepoId, storage, logger)
} else {
repoCollector, err = parser.NewLibgit2RepoCollector(localDir,
op.RepoId, storage, logger)
}
if err != nil {
return err
}
// inject clean up callback to remove the cloned dir
cleanup := func() {
_ = os.RemoveAll(localDir)
}
if e := repoCollector.SetCleanUp(cleanup); e != nil {
return errors.Convert(e)
}
// pass the collector down to next subtask
taskData.GitRepo = repoCollector
subTaskCtx.TaskContext().SetData(taskData)
return nil
}
```
### Additional Troubleshooting Steps
1. **Self-Signed Certificates**: If you are using a private GitLab server
with a self-signed certificate, add your root CA to the `devlake` container.
Mount your `rootCA.crt` into the container and update the CA certificates.
Example for `docker-compose`:
```yaml
devlake:
image: apache/devlake:v...
...
volumes:
...
-
/path/to/your/rootCA.crt:/usr/local/share/ca-certificates/rootCA.crt
command: [ "sh", "-c", "update-ca-certificates; lake" ]
...
```
2. **Upgrade to Latest Version**: Consider upgrading to the latest version
of DevLake (v0.15.x or later) as some bugs have been fixed in newer versions.
3. **Check Token Permissions**: Ensure that your access token has the
necessary permissions. If your account is protected by organization SAML
enforcement, make sure you've authorized the token using SSO.
4. **Error Code 403**: If you encounter an error with the status code 403,
it is usually caused by the permission of your tokens. Ensure you are using a
supported authentication method and that your token has the necessary
permissions.
5. **Error Code 429**: If you encounter an error with the status code 429,
it is usually caused by rate limiting. Enable `fixed rate limit` in the GitLab
connection and lower the API rates to 2,000. If it works, you can try
increasing the rates to accelerate
