It hangs when ignore entry starts with / #99
Description
Vitest issue: vitest-dev/vitest#7598
reproduction: https://stackblitz.com/edit/github-koqytcnx?file=repro-tinyglobby.js
Vitest users reported an issue after switching to tinyglobby in Vitest 3.0.6. For Vitest use cases, this is mostly considered as a user side mis-configuration, so it's not critical, but it looks like something unintended going on, so I reduced the repro and report it here.
On stackblitz, it doesn't hang and glob returns empty, so the underlying issue might be same as #94.
Here is the code:
import { globSync } from 'tinyglobby';
console.time('tinyglobby');
const files = globSync(['demo.test.ts'], {
ignore: ['/xxx/**'],
expandDirectories: false,
debug: true,
});
console.timeEnd('tinyglobby');
console.log('\n==== files ====');
console.log(files);On my linux pc:
$ node repro-tinyglobby.js
