We have several tests that were ignored back when we were waiting for fast-glob fixes. Because we no longer use fast-glob, the tests now work.

Test updates

What changes did you make? (Give an overview)

There were several tests that we were ignoring for FlatESLint due to bugs in fast-glob. Now that we no longer use fast-glob, we can make these tests run.

Is there anything you'd like reviewers to focus on?

I changed the last test a bit because ignores works a bit differently than ignorePatterns did. Please double-check that change.

Seems like there was some timing issues where just root was colliding due to Mocha running some tests in parallel, so I made them unique.

path.join(root, "node_modules/foo/index.js")
path.join(getPath(), "eslint.config.js"),
path.join(getPath(), "foo.js"),
path.join(getPath(), "node_modules/foo/.dot.js"),

We now include dot files by default, so had to update tests accordingly.

ignores: ["**/eslint.config.js", "!node_modules/myconf", "foo/*.js"],

Remove "**/eslint.config.js" from this array. With ignorePatterns, that file would be ignored; with ignores, the file isn't ignored due to "!node_module/myconf unignoring the whole directory, which overrides "**/eslint.config.js".

ignores: ["**/eslint.config.js", "!node_modules/myconf", "foo/*.js"],

Had to separate into a different config object so ignores is treated as global ignores.

I wouldn't expect this pattern to have any effects after **/node_modules/**.

**/node_modules/**
!**/node_modules/foo/**

The first test below asserts that node_modules/foo/index.js is not ignored. I think that this file should be ignored because it's in ignored directory node_modules/foo.

**/node_modules/** ignores node_modules/foo, but !**/node_modules/foo/** does not unignore it.

Hmmm, are you sure about that? it seems like this test was indicating our behavior worked in a different way.

Generally we are treating patterns ending with star-str as file matchers and not directory matchers.

Here is the current test, which verifies this behavior:
https://github.com/eslint/eslint/blob/main/tests/lib/eslint/eslint.js#L5413-L5460

In the original test, the list of patterns is:

/**/node_modules/*
!/node_modules/foo

node_modules/ doesn't match any patterns; node_modules/foo/ matches /**/node_modules/* but also matches a subsequent negative pattern !/node_modules/foo so it's not ignored; node_modules/foo/index.js doesn't match any patterns.

In the flat eslint test, the list of patterns is:

**/node_modules/**
!**/node_modules/foo/**

node_modules/ doesn't match any patterns; node_modules/foo/ matches **/node_modules/** and doesn't match any negative patterns so node_modules/foo/ is ignored and thus node_modules/foo/index.js should be ignored because it's in an ignored directory.

Generally we are treating patterns ending with star-str as file matchers and not directory matchers.

I think it would be confusing if trailing /** doesn't match subdirectories, as it is expected to match everything.

In my opinion, foo/** pattern should not match foo/ directory, but it should match foo/bar/ directory. This is how gitignore works. In minimatch, however, foo/** does match foo/ directory, but that may be a bug (isaacs/minimatch#179).

Looks like that minimatch behavior is intentional.

I'll take some time to look at this again...it's such an edge case that I think there's room for disagreement on how to handle this. Because we are not explicitly guaranteeing to work the same way gitignore works, I think we can kind of chart our own course here.

So interestingly, it appears that ConfigArray actually works the way you describe. I added some tests to verify:
humanwhocodes/config-array#73

It looks like there must be a bug on the ESLint side of things, so I'm investigating that next.

So it actually looks like it's a bug in isDirectoryIgnored() as opposed to isFileIgnored().

!node_modules/myconf also shouldn't have any effects after **/node_modules/**. because it unignores the directory but everything under it is still ignored by **/node_modules/**.

Here is the original test: https://github.com/eslint/eslint/blob/main/tests/lib/eslint/eslint.js#L6426-L6459

This is a bit different because in eslintrc the default pattern is /**/node_modules/* (* instead of ** at the end is the difference; leading slash doesn't matter), so in the original test the list of patterns is:

/**/node_modules/*
!/node_modules/myconf

node_modules/ doesn't match any patterns; node_modules/myconf/ matches /**/node_modules/* but also matches a subsequent negative pattern !/node_modules/myconf so it's not ignored; node_modules/myconf/foo/ doesn't match any patterns; node_modules/myconf/foo/test.js doesn't match any patterns.

In the flat eslint test, the list of patterns is:

**/node_modules/**
!node_modules/myconf

node_modules/ doesn't match any patterns; node_modules/myconf/ matches **/node_modules/* but also matches a subsequent negative pattern !node_modules/myconf so it's not ignored; node_modules/myconf/foo/ matches **/node_modules/** and doesn't match any negative patterns so that should be the end - directory node_modules/myconf/foo/ is ignored and thus everything under it is ignored as well, including node_modules/myconf/foo/test.js.

After digging deeply into this, it appears that this wasn't just a chore, but actually we needed a bug fix, so I've switched this PR to "fix".

I've updated the default ignore pattern for flat config to be **/node_modules/* to match what we have for eslintrc. This, plus an update of config-array now makes flat config unignores work similarly to eslintrc.

Hmmmm, it looks like tests are failing on Node.js 19 only...no idea why that would be. I even downloaded Node.js 19 locally and can't reproduce. 🤔 No more time to look into this today, so if anyone has any ideas, I'd appreciate the help.

Seems that the problem is file: with recently released npm v9.2.0 which is included in recently released Node v19.3.0.

@mdjermanovic

This is actually npm major upgrade v8 -> v9, so there must be a breaking change in v9 that's causing this. On the latest working commit it was { node: 'v19.2.0', npm: '8.19.3' }, now it is { node: 'v19.3.0', npm: '9.2.0' }.

docs/** pattern now ignores docs/ directory? This is observable from running npm run lint:docsjs ( runs eslint docs/.eleventy.js):

C:\milos\eslint\docs\.eleventy.js
  0:0  warning  File ignored by default.  Use a negated ignore pattern (like "--ignore-pattern '!<relative/path/to/filename>'") to override

✖ 1 problem (0 errors, 1 warning)

I think this is good, because this is how minimatch works, and whatever we try to adjust in minimatch's behavior probably won't work 100% correctly, just wanted to check with you if this is intentional because config-array docs still state that it shouldn't match, here.

Oops yes, that is intentional. I just forgot to update the config-array docs:

Test title doesn't match the assertion in the test.

The assertion is correct. node_modules/foo/ is ignored by default, but since **/node_modules/foo/** now matches node_modules/foo/, !**/node_modules/foo/** will unignore it, so the files inside are not ignored.

assert.strictEqual(await engine.isPathIgnored("node_modules/foo/index.js"), false);
});

LGTM, thanks! I'll prepare a follow-up to fix #16579 (comment) and to update ignore patterns in our config file. Not a blocker for the release.
