To resolve the "plain clone git error" in the gitextractor job when
collecting data from an on-premise GitLab using DevLake (v0.21.0@ac4f7fe) with
Docker Compose, you can follow these steps:
1. **Check the Proxy Configuration**: Ensure that the proxy settings are
correctly configured if you are using a proxy. The code supports both
HTTP/HTTPS and SSH proxies.
2. **Verify the Private Key**: If you are using SSH with a private key, make
sure the private key is correctly handled and the passphrase (if any) is
correctly set.
3. **Disable Shallow Clone**: If the error persists, try disabling the
shallow clone by setting `NoShallowClone` to `true` in the `CloneRepoConfig`.
Here is an example of how you can modify the `CloneRepoConfig` to disable
shallow cloning:
```go
type CloneRepoConfig struct {
UseGoGit *bool
SkipCommitStat *bool
SkipCommitFiles *bool
NoShallowClone bool
}
// Example usage
config := CloneRepoConfig{
NoShallowClone: true,
}
```
4. **Check SSL Verification**: If you are using HTTPS and facing SSL
verification issues, you can disable SSL verification by setting the
`IN_SECURE_SKIP_VERIFY` configuration to `true`.
5. **Repack and Deepen Commits**: The code already includes a mechanism to
repack and deepen commits to avoid certain errors. Ensure this part of the code
is executed correctly.
Here is the relevant part of the code for repacking and deepening commits:
```go
// deepen the commits by 1 more step to avoid
https://github.com/apache/incubator-devlake/issues/7426
if since != nil {
// fixes error described on
https://stackoverflow.com/questions/63878612/git-fatal-error-in-object-unshallow-sha-1
// It might be caused by the commit which being deepen has multiple
parents (e.g., a merge commit), not sure.
repackCmd := exec.CommandContext(ctx.GetContext(), "git", "-C",
localDir, "repack", "-d")
if err := repackCmd.Run(); err != nil {
return errors.Default.Wrap(err, "failed to repack the repo")
}
deepenCmd := exec.CommandContext(ctx.GetContext(), "git", "-C",
localDir, "fetch", "--deepen=1")
if err := deepenCmd.Run(); err != nil {
return errors.Default.Wrap(err, "failed to deepen the cloned repo")
}
}
```
6. **Ensure Proper Cleanup**: The `CloneGitRepo` function includes a cleanup
callback to remove the cloned directory after the operation. Make sure this
cleanup is properly set to avoid any residual issues.
Here is the relevant part of the `CloneGitRepo` function:
```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
}
// 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
}
```
By following these steps, you should be able to resolve the "plain clone git
error" in the gitextractor job
