Your org has enabled the Graphite merge queue for merging into main

Add the label “merge” to the PR and Graphite will automatically add it to the merge queue when it’s ready to merge. Or use the label “hotfix” to add to the merge queue as a hot fix.

You must have a Graphite account and log in to Graphite in order to use the merge queue. Sign up using this link.

@Dunqing Can you test rolldown before making a release when you wake up?

Yes, I can

Cool, click Merge without waiting for requirements to be met (bypass branch protections) + squash and merge once you're done.

https://github.com/rolldown-rs/rolldown/blob/main/crates/rolldown/tests/fixtures/rollup/catch-scope-shadowing/main.js#L20

import assert from 'assert';
var e = 'failed1',
  x = 'value';

(function () {
  try {
    // empty
  } catch (e) {
    var e = 'failed2';
  }

  assert.strictEqual(e, undefined);
  assert.strictEqual(x, undefined);
  x = 'failed3';
  return;

  try {
    not_reached();
  } catch (x) {
    var x = 'failed4';
  }
})();

assert.strictEqual(x, 'value');

Out

import { default as assert } from "assert";

//#region main.js
var e = "failed1", x = "value";
(function() {
	try {} catch (e$1) {
		var e$1 = "failed2";
	}
	assert.strictEqual(e, undefined);
	assert.strictEqual(x$1, undefined);
	x$1 = "failed3";
	return;
	var x$1;
})();
assert.strictEqual(x, "value");

//#endregion

Expected

import { default as assert } from "assert";

//#region main.js
var e = 'failed1', x = 'value';
(function() {
	try {} catch (e$1) {
		var e$1 = 'failed2';
	}
	assert.strictEqual(e$1, undefined);
	assert.strictEqual(x$1, undefined);
	x$1 = 'failed3';
	return;
	try {
		not_reached();
	} catch (x$1) {
		var x$1 = 'failed4';
	}
})();
assert.strictEqual(x, 'value');

This test failed because the scope changed. I am working to figure it out.

Closing this. See #4338

Do we have a command to update the branch instead of creating another PR?

Nope, but you can update manually.
