Typescript import paths are suddenly traversing upwards since upgrading from 1.19.3

[alextreppass]

• VSCode Version: 1.20.1
• OS Version: OSX
• Does this issue occur when all extensions are disabled?: Yes

Given the following files:

• src/some/path/to/consumer.ts
• src/some/other/path/util.ts

When editing consumer.ts to import a member of util.ts, VSCode will suggest and import the following:

• In 1.19.3: import { thing } from 'some/other/path/util';
• In 1.20.1: import { thing } from '../../other/path/util';

In our codebase, we have the compiler option baseUrl set to ./src. We have no other path-related settings.

Restrictions:

• I can't change the baseUrl as we don't want to see src/ pre-pended to our imports,
• We need the full path (without src/ prepended) for easy grepping and refactoring.

Is there a way to get the old behaviour back here?

I've tried playing around with the paths and rootDirs compiler options but have had no luck.

Thanks,

These might be the causes:

microsoft/TypeScript#19920

microsoft/TypeScript@d333d88

[alextreppass]

Confirmed that reverting microsoft/TypeScript@d333d88 brings back the desired import behaviour

Have opened microsoft/TypeScript#22249 for discussion

Thanks for looking into this @alextreppass! I'm going to close this issue as upstream. We'll continue discussion up on the TypeScript issue

Should be solved by #45948
