Windows watch mode fix #3563

scottambroseio · 2017-05-13T18:23:23Z

Summary

Test plan

Run the 'can select a specific file name from the typeahead results' test in watch-filename-pattern-mode-test.js on both Windows and Unix based systems

gaearon · 2017-05-16T16:17:27Z

This fixes the issue in my testing. Can we please get it in?

thymikee · 2017-05-16T16:34:26Z

Feel free to stamp it and @cpojer will merge soon. We could cut a patch release for that I think, but would need to double check for breaking changes

cpojer · 2017-05-16T16:48:18Z

Yes we can do a patch with this tomorrow. Seems like this diff has lint errors, though. Can you fix them up and make CI pass?

thymikee · 2017-05-16T16:57:24Z

Although I'm not super happy we use a third party until just for that, but didn't have time to check what it does, maybe it's reasonable.

cpojer · 2017-05-16T16:58:30Z

Yeah, it's only used in the test file – can we inline it rather than adding a dependency?

Why can't we use require('jest-regex-util').replacePathSepForRegex; in the test as well?

cpojer · 2017-05-16T16:58:45Z

packages/jest-cli/src/watch.js

 const isValidPath = require('./lib/isValidPath');
 const preRunMessage = require('./preRunMessage');
+const replacePathSepForRegex = require('jest-regex-util').replacePathSepForRegex;


nit: const {replacePathSepForRegex} = require('jest-regex-util');

Hey, just caught up on this.

You can see my last two comments at #3516 which explains the idea behind regex-slash. I wasn't sure whether to inline it, or make it a dependency like slash. I went the dependency route as I figured being like slash, other's might find it useful. The source is here https://github.com/scottrangerio/regex-slash/blob/master/index.js, it's just a one line function,

module.exports = (pathPattern) => pathPattern.replace(/\\\\/g, '/');

so it would be super easy to inline. I'm not a master at regex, so I'm not sure if there's a more optimal / better regex pattern?

As for using replacePathSepForRegex in the test, this is the result.

The test uses a snapshot of a Unix style path pattern. So on windows, for the test to pass, we need a function of the form

// path\\to\\file.js -> path/to/file.js

to match the snapshot so the test passes on Windows.

I'll push the code review fix in a moment. I'm happy to add that helper function to jest-regex-util if that's preferred.

 const isValidPath = require('./lib/isValidPath');
 const preRunMessage = require('./preRunMessage');
+const { replacePathSepForRegex } = require('jest-regex-util');


nit: remove the spaces.

cpojer · 2017-05-16T18:21:57Z

Can we just inline this in the test? The function is not needed outside the test itself.

Proposal:

Inline the function.
Run yarn lint locally and fix the CI issues.

gaearon · 2017-05-16T20:18:57Z

@scottrangerio If you don't mind I'll fix up the nits and push to your branch.

Can you explain why we need to replace two backslashes with a single slash? Where does the second backslash come from?

I guess because we're dealing with a pattern, so it needs an escape.

This was the original problem the function is trying to fix

Due to the backslashs needing escaping, the way I understand it is that behind the hood path\\to\\file is actually path\\\\to\\\\file, if that makes sense?

Edit: Yeah, you summarised it better than I could.

Seems like this is ready. I would really appreciate a patch for this.
