How to update parser for TiDB

Assuming that you want to file a PR (pull request) to TiDB, and your PR includes a change in the parser, follow these steps to update the parser in TiDB.

Step 1: Make changes in your parser repository

Fork this repository to your own account and commit the changes to your repository.

Note:

  • Don't forget to run make test before you commit!
  • Make sure parser.go is updated.

Suppose the forked repository is https://github.com/your-repo/parser.

Step 2: Make your parser changes take effect in TiDB and run CI

  1. In your TiDB repository, execute the replace instruction to make your parser changes take effect:

    GO111MODULE=on go mod edit -replace github.com/pingcap/parser=github.com/your-repo/parser@your-branch
    
  2. make dev to run CI in TiDB.

  3. File a PR to TiDB.

Step 3: Merge the PR about the parser to this repository

File a PR to this repository. Link the related PR in TiDB in your PR description or comment.

This PR will be reviewed, and if everything goes well, it will be merged.

Step 4: Update TiDB to use the latest parser

In your TiDB pull request, modify the go.mod file manually or use this command:

GO111MODULE=on go get -u github.com/pingcap/parser@master

Make sure the replace instruction is changed back to the require instruction and the version is the latest.

You can’t perform that action at this time.
