@cfzjywxk I just learn that you should remove "do-not-merge" label manually to proceed the PR.

@Mini256 please take a look at this issue. I'm afraid we're blocked for any changes on sessionctx/variable. It is weird that after a config reviewer ( @cfzjywxk ) review or remove the label, it is still there.

[ti-chi-bot]

@tisonkun: Illegal modification of do-not-merge/blocked-paths label.

In response to removing label named do-not-merge/blocked-paths.

At the same time I will also trigger all tests for you:

If the CI test fails, you just re-trigger the test that failed and the bot will merge the PR for you after the CI passes.
