tools: custom eslint autofix for inspector-check.js #16646

shobhitchittora · 2017-10-31T19:16:47Z

This adds eslint fixer method for inspector-check.js. When running eslint with --fix flag, the fixer will add common.skipIfInspectorDisabled(); to the file automatically.

See my comment in the other PR re: creating tests for these to verify they're working as expected. Thanks!

+        fix: (fixer) => {
+          return fixer.insertTextAfter(
+            node,
+            '\n\n common.skipIfInspectorDisabled();'


What does the node refer to in this context? I feel like this might be getting inserted in the wrong place.

Also, why the errant space after \n\n?

You are right. This inserts the correction at the end of the file. Working on inserting it below require('../common'). Also will fix space after\n\n.

Made a new commit fixing the same. Please verify. Thanks.

@shobhitchittora Could you run make test on this PR? It looks like the test for this is failing here…

apapirovski · 2017-12-09T20:59:54Z

I won't outright block this but I'm -1 on landing this. I really don't like the idea of auto fixing these skip checks because of the potential for things going really wrong. The fact that it has to lookup an entirely unrelated part of the code to insert the check is concerning. There are so many different possibilities for what a require that passes that RegExp could actually be requiring.

shobhitchittora · 2017-12-10T13:06:24Z

@addaleax I'm getting 68 errors while running make -j4 test on the latest master. Getting errors while Running Markdown linter on docs....

tools/eslint-rules/inspector-check.js

  var hasInspectorCheck = false;

  function testInspectorUsage(context, node) {
    if (utils.isRequired(node, ['inspector'])) {
      missingCheckNodes.push(node);
    }
+
+    if (utils.isCommonModule(node)) {
+      commonModuleNodes.push(node);


Since there is only one required (and only one should be present) using an array here is actually not necessary and a simple assign would be enough as well.

Yup correct. Fixing this.

We normally do not use multiline template strings. It will work in this case but it was very hard for me to even see that it is a template string and not three individual entries. So it would be great to change that to either a single line or +.

@shobhitchittora is this definitely going to work and will it also insert require("common"); here? Because I do not see this happening in the fixer.

AssertionError [ERR_ASSERTION]: Output is incorrect.

@starkwang How did you check the diffs for the test runner?

BridgeAR · 2018-02-07T03:13:02Z

@shobhitchittora I am not sure what your question is really about. Can you elaborate so someone else might also be able to answer that question?

shobhitchittora · 2018-02-07T03:29:16Z

@BridgeAR I'm stuck as the test for the rule is failing, throwing -

AssertionError [ERR_ASSERTION]: Output is incorrect.

While running - python ./tools/test.py parallel/test-eslint-inspector-check I'd like the test-runner to show me the expected and actual output received, i.e, the diff ( similar to what @starkwang did for a previous PR of ours).

PS: I tried adding/removing 'require("common");\n' + from the output of the test, but it's not working.

BridgeAR

Please check the comments and I recommend to rebase. That way you get a better error output. Please also add a new test case that checks code that imported common.

This is very certain not the correct output as common was not imported in the checked code.

Please either use a single code line (I would do that as in the example above the added one) or indent the code so the concatenated part is deeper indented than the start of the string.

Here the access to the first argument has to be guarded. In case a node has no arguments, this will trigger an error.

So please add a node.arguments.length !== 0 && in the middle.
