tty.getWindowSize is not a function inside a "worker_threads" worker #3955

merged 2 commits into from Jul 20, 2019

Description of the Change

Thanks for reviewing this PR. I'm the maintainer of mocha-parallel-tests - a wrapper on top of mocha which runs mocha tests in either parallel processes forked via child_process or in parallel threads created with worker_threads.

Recently I added an opportunity to run mocha tests via worker_threads if the API is available (IIRC this should be node@12). I got a couple of reports saying that tty.getWindowSize is not a function. I spent a big amount of time investigating the issue and I discovered that the root cause is the worker_threads environment. While I understand this is probably not an issue with mocha because it never runs in worker_threads-created threads, I believe that people like me still might run mocha in threads for different reasons. And it looks like tty.isatty(fd) behaves wrong in worker_threads. I'm not even sure if it's a Node.JS issue or not, but process.stdout.isTTY is False in worker_threads environmentwhereastty.isatty(1)` is True. This leads to the issue people reported.

I have a monkey-patch fix for my repository but I believe we can improve mocha here and this issue will be solved not only for mocha-parallel-tests but also for other thread-based environments.

I also raised an issue inside Node.JS repo.

Why should this be in core?

Everyone who runs mocha in a worker_threads-created worker will have this issue.


Everyone who runs mocha in a worker_threads-created worker will not have this issue.

I'm not sure that the error in the build has anything in common with this PR.

Also, I got an interesting response in the Node.JS repo:

This still seems like expected behaviour – fd’s are per-process, so fd 1 is going to be a TTY in one thread if it is a TTY for any thread. The problem is that in Workers, process.stdout does not refer to fd 1.

I'd say it makes the change in this PR more reasonable.

@1999 I haven't really understood this PR. But we are going to cut a new release soon.
Is Mocha taking any risk by this change?
Neither in POSIX nor in Windows environment?

1999 commented Jun 29, 2019

This change is backwards compatible. It only fixes the bug when mocha is running inside a worker environment - base reporter throws an exception right now.

But we are going to cut a new release soon.

Is there any chance we can discuss parallel tests executed inside mocha? Ideally, I want to merge mocha-parallel-tests code into mocha or at least make it an optional runner.

@1999 I will wait with this PR, maybe we get some more feedbacks within the next few days.
Why do you use the Boolean() function?

Is there any chance we can discuss parallel tests executed inside mocha?

From my side, no, there are still important runner bugs to fix like eg hook pattern issues. Reviews on runner issues are normally rather difficult to get.

Gotcha. As for Boolean, I can remove that. Just wanted to make it explicit that isTTY property is not always boolean - it can be undefined as well. But yeah, technically Boolean is not a must here.

* docs(lib/mocha.js): Update API documentation (#3515)

### Description of the Change

Replaced all method headers with more complete documentation, better following recommended styles. Eliminated `@api` tags, as `@access` _should_ imply same. Used `@chainable` to denote class methods returning `this` instance.

Renamed a handful of variables, but **no logic changes**!

### Alternate Designs


### Why should this be in core?


### Benefits

API documentation will be more useful if more complete.

### Possible Drawbacks


### Applicable issues

* docs: improve and fix/remove links

* docs: link to in readme

* docs: address PR comments [skip ci]

* docs: better wording on PR review wait time [skip ci]

* level -> label (#3477)

* test(test/reporters/base.spec.js): Fix Base reporter test failure due to timeout

The `Base` reporter's specification verifies reporter can interpret Chai custom error messages. This
test takes ~480ms (lightly loaded CPU), which is _way_ too close to the 500ms timeout. Change
doubles this timeout.

* Extract `runReporter` to capture output under tests (#3528)

While refactoring the `dot` reporter test, we created a method for capturing output from running the reporter. It proved so handy at squelching test "noise" that JeongHoon extracted it and applied it to many of the other reporters.

* update list of published files in package.json

- this will fix a problem with npm (potentially) publishing certain files
which should always be ignored; see npm/npm-packlist#14.
- also fixes issue with growl images not getting published!
- add `directories` property for metadata

PRO TIP: use `npm pack --dry-run` to see what would be included in
published tarball.

* Prevent timeout value from skirting limit check (#3536)

* fix(lib/runnable.js): Prevent timeout value from skirting limit check
   - Moved the timestring->value translation code to before the limit check.
   - Found that previous "fix" hadn't actually fixed the correct value, as the wrong upper bound value had been used (off by one error). 
   - Further research indicated that some versions of IE had problems with negative timeout values. New code clamps to nonnegative numbers ending at `INT_MAX`.
   - Updated the function documentation.

* feat(lib/utils.js): Add `clamp` function
   - New function clamps a numeric value to a given range.

* test(unit/runnable.spec.js): Updated tests for `#timeout(ms)`
   - Restructured `Runnable#timeout` tests to check both numeric/timestamp input values that:
      - less than lower limit
      - equal to lower limit
      - within limits
      - equal to upper limit
      - greater than upper limit

Closes #1652

* Added TAP specification 12 output producer [default].
* Added `reporterOptions.tapVersion` to target TAP producer.
* Refactored to make use of `runner.stats`
* Refactored to use `process.stdout` stream exclusively.
* Updated to test against both specifications and incorporate work from PR #3528.
* Added integration tests for specification conformance.

* Add ability to query Mocha version programmatically (#3535)

* Added new public `version` property to `Mocha`, available in both Node and browser.
* Used `browserify` transform to prevent exposing any other package details (for security).

* Fix link in changelog (#3566)

* ci(appveyor.yml): Fix Growl install (#3577)

Use GitHub URL for downloading GfW installer.

* ci(.travis.yml,appveyor.yml): Use current npm version in CI scripts (#3579)

The requirement for using npm-5.x was due to npm-6 dropping support for Node-4. Since Mocha now requires Node-6+, we should use the current verion of npm. This will also eliminate npm
"Unsupported Node version" warnings when run against Node-11+.

* docs: Add more details regarding suite-level skip.

* test: Update error messages in before hook integration tests.

* test: Remove timeout delays from pending tests.

* fix(cli): Throw error if unable to parse Mocha options file

Code now throws an error for any problems (except nonexistent default "test/mocha.opts"). Includes

Fixes #3363 Fixes #2576

* use yargs for option parsing and support config files

- `-d` is no longer an alias for `--debug`
- `--grep` and `--fgrep` are now mutually exclusive
- The option formerly known as `--compilers` is now removed from Mocha
- `lib/template.html` moved to `lib/browser/template.html`
- An error is thrown if a path to `mocha.opts` is specified by the user and the file was not found

- `-gc` users should use `--gc-global`

- Public API method `getOptions()` in `bin/options.js` is deprecated and currently has no alternative
- Users of the `enableTimeouts` option of the `Mocha` constructor should use `timeout` instead.  Specify `false` for no timeout
- Users of the `useColors` option of the `Mocha` constructor should use `color` instead

- Mocha now supports JS, JSON, YAML, or `package.json`-based config.
- Any/all configuration, including `mocha.opts` can be used in addition to command-line arguments, and everything will be merged as applicable
- Node/V8 flag support:
  - Support of all available `node` flags on a *per-version* basis
  - Support of any V8 flag by prepending `--v8-` to the option
  - These are supported within `mocha.opts` or config files
- More flexible command-line parsing including negation of any boolean flag by prepending `--no-` to the name
- Better `--help`
- Descriptions of interfaces in `--help` text
- A useful `Mocha` constructor

* avoid global timers by way of ESLint; closes #3342 (#3374)

- Remove unused variables to avoid problems with #237 (and their associated inline ESLint directives)
- Use existing ESLint rules (`no-restricted-globals`, `no-restricted-modules` and `no-restricted-syntax`) to disallow global timer access.
- Removed "poison pill" tests in `test/unit/runnable.spec.js`.

For those rules, our config applies only to `bin/*` and `lib/**/*.js`.

- `no-restricted-globals`: Disallow bare references (including calls) to timers like `setTimeout`.
- `no-restricted-modules`: Disallow use of Node.js' `timers` module to get around the above restriction.
- `no-restricted-syntax`: 
  - Disallow calls of `global.setTimeout` and other timers
  - Disallow `new global.Date()`
  - Disallow any expressions involving `global.Date.*`, `global.setTimeout.*` and other timers

- add more files to markdown linting
- reorg tests, remove `fs` test from jsapi tests

* Growl: Web notifications & Desktop prerequisite software check (#3542)

Added (minorly brittle) means to verify prerequisite software
is installed. Migrated Growl support code to its own file. This
implementation's checks are required to enable Growl; failure
will write notice to `stderr`. Other modifications based on
discussion from Chad Rickman's PR #3311. This also checks for
errors from Growl callback.

Provided browser notification support as well for modern browsers
by replacing the existing noop stub with an implementation for web
notifications via the Mocha `growl` pseudo-reporter (when run in browser).

Updated user guide and wiki for desktop notification support.

### Description of the Change

#3656 added a couple utils for setting `code` on errors. I fixed a couple here and wanted to make sure I was on the right track before making more changes.

### Alternate Designs


### Why should this be in core?

Codes help identify errors as mocha errors at a glance without using custom error types, and better DX is always good.

### Benefits


### Possible Drawbacks

None that I can see

* Add image type to ppreload of opencollective fallback avatar

* Stop preloading tracking scripts. They mess with the loading order and slow page rendering down

* Fix messages for file lookup issues - error scenario (#3654); see #3646

Scenario where multiple files (all) are not found only show a single message.
I feel its useful for debugging to keep the message if only 1 file is not found. Happy to remove if others don't agree.

No changes where at least 1 is found (still prints msg).

* do not recursively call `process.exit()`

When inside `process.on('exit')`, calling `process.exit()`
stops other `exit` event listeners from being invoked.

This has lead to issues with coverage generation with `nyc`
because a fallback exit detection mechanism in it that relies
on internal Node.js APIs was accidentally disabled in Node v11.7.0,
leaving `nyc` with no way to detect process exit.

* Fix Hook Test Names (#3573); closes #1638, closes #3291, closes #2134

### Description of bug
Mocha shows an incorrect test-title if a nested `before` hook fails. For `after` hooks the second part of the message is completely missing.
describe('Top-level describe', () => {
  it('Top-level it', () => { });       // the failing before-hook is pointing to this test
  describe('Nested describe', () => {
    before(() => {
      throw new Error();
    it('Nested it', () => { });        // but it should point to this test
Top-level describe
    ✓ Top-level it
    Nested describe
      1) "before all" hook for "Top-level it"       <<<incorrect
Root problem: see [#1638]( `hook.ctx.currentTest` is set incorrectly in the hook before emitting the hook event:
- `before` hook: currentTest is undefined or points to the outer test already past successfully.
The runner hasn't reached the next test to come yet, so it's too early to derive currentTest from the runner. Instead the first test of hook's parent is used.
- `after` hook: currentTest is undefined.
The runner has already completed the latest test and runner.currentTest is deleted. Instead the last test of hook's parent is used.

### Description of the Change
#### 1. Setting currentTest correctly
- `before` hook: hook.ctx.currentTest is set to the first test of the parent suite
- `after hook`: hook.ctx.currentTest is set to the last test of the parent suite
- for nested suites just the current suite is searched for tests to come. When no tests can be found, currentTest remains undefined.

#### 2. Creating title in hook failure message
A correct `hook.ctx.currentTest` renders a correct title. 
When no currentTest can be found, the title of the parent suite is used for the hook failure message.

* Fix regexp in utils.stackTraceFilter to prevent ReDoS #3416 (#3686)

When the stacktrace begins with a large `Error.message` (single or multi line), Mocha's stack prettifier method (enabled by default) takes a long time to finish due to its regular expression. Certain assertions (e.g., `contains`, `deeplyEqual`) against large objects can trigger this problem.
This PR alters the RegExp to skip over the error message portion of the stacktrace.

* More, improved integration tests for watching (#3929)

To extend the test coverage for mocha in watch mode we add the following
two tests:
* Check that test files are reloaded
* Check that watched dependencies are reloaded

To support this change we consolidate `runMochaJSONWatchAsync`,
`runMochaJSONRawAsync`, and repeated code in tests into `runMochaWatch`.
We introduce `invokeMochaAsync` in `test/integration/helpers` as an
async alternative to `invokeMocha`.

We also eliminate the test for the cursor control character in the
output. Its usefulness is dubious as it relies on an implementation
detail and the other tests cover the intended behavior.

We are also more explicit which test fixtures are used. Instead of
setting `this.testFile` in a `beforeEach` hook we do this explicitly for
the tests that require it. This prevents interference in tests that do
not use the file.

* Collect test files later (#3953)

This commit prepares improvements to the watch mode behavior. In the future
we want Mocha in watch mode to pick up new test files. This requires
that the test files are collected inside `watchRun` instead of before.

To accomplish this change we rename `handleFiles` to `collectFiles` and
move it to its own module. Instead of calling `collectFiles` in
`lib/cli/run` and passing the files on to `watchRun` or `singleRun` we
pass down the file collection parameters through `runMocha` and call
`collectFiles` in both `watchRun` and `singleRun`.

* Don't re-initialize grep option on watch re-run (#3960)
