<!-- Answer -->
To implement the suggestions for mitigating the out-of-memory error in
DevLake's gitextractor plugin, follow these steps:
1. **Enable Shallow Cloning**:
- Ensure that the `NoShallowClone` option is set to `false`. This allows
the use of the `shallowClone` method, which fetches only the latest commits.
- Check the `CloneRepoConfig` struct in the code to verify this setting
<sup>[[1]](https://github.com/apache/incubator-devlake/blob/main/backend/plugins/gitextractor/parser/clone_gitcli.go)</sup>.
2. **Adjust Configuration Options**:
- Modify the configuration file or API request to set `SkipCommitStat`
and `SkipCommitFiles` to `true`. This reduces the amount of data processed.
- Verify that `UseGoGit` is set to `false` by checking the configuration
settings. If not explicitly set, it defaults to `false`
<sup>[[2]](https://github.com/apache/incubator-devlake/blob/main/backend/plugins/gitextractor/impl/impl.go)</sup>.
3. **Configure Batch Processing**:
- Adjust the `BatchSaveDivider` batch size in the `NewDatabase` function.
The default batch size is 100, but you can modify it to a smaller value if
needed to manage memory usage
<sup>[[3]](https://github.com/apache/incubator-devlake/blob/main/backend/plugins/gitextractor/store/database.go)</sup>.
4. **Consider Double Cloning**:
- If shallow cloning is insufficient, you might need to implement the
`doubleClone` method. This involves performing a full clone into an
intermediary directory followed by a shallow clone. Ensure that the
`NoShallowClone` option is set appropriately to enable this method
<sup>[[1]](https://github.com/apache/incubator-devlake/blob/main/backend/plugins/gitextractor/parser/clone_gitcli.go)</sup>.
By following these steps, you can optimize the gitextractor plugin's
performance and reduce memory usage during the cloning process.
