Return exit code 1 when incomplete tasks are detected #145

barbogast · 2018-01-13T18:00:44Z

Looks like this could be a fix for gulpjs/gulp#2081

phated · 2018-01-13T22:05:01Z

Please add tests and make sure you aren't breaking old versions. process isn't a module and is just a global.

sttk · 2018-01-14T04:45:26Z

@phated Should we treat this for gulp v3? It is possible by modifying events.js.

phated · 2018-01-14T05:49:17Z

Sure! Anything that is easily backported should be.

sttk · 2018-01-14T06:33:45Z

@barbogast Could you also implement for gulp v3? Regarding tests on v3, since we will address them in the issue #139, you may write only a unit test for logEvents in events.js.

barbogast · 2018-01-17T08:07:22Z

I just added a test and removed the require('process') call.

I'd try to backport the change to gulp v3 but to me it looks like gulp v3 doesn't detect incomplete tasks but just exits the process.

The integration tests fail for nodejs 0.10 as expected (see gulpjs/gulp#2081 (comment)). Is there a way to skip the test for nodejs 0.10?

phated · 2018-01-17T21:46:24Z

if (!('exitCode' in process)) {
  this.skip();
}

Should work???

barbogast · 2018-01-18T20:49:06Z

I'm pretty sure that this wouldn't solve the problem. The code didn't crash. Only the test failed because the process didn't exit with an error code (as is expected for nodejs 0.10). We need a way to disable this test case for nodejs 0.10. We could parse process.version and skip the test for nodejs < 0.11. Kind of hacky, bit it should work...

phated · 2018-01-18T20:54:47Z

That goes in the test to skip it. The property won't exist in old node

barbogast · 2018-01-18T21:44:59Z

Oh, sorry, I didn't understand. I just checked, and exitCode is not present on process (except when it's set explicitly).

We could detect the node version using https://github.com/phated/sver-compat

+  it('should return error code 1 if any tasks did not complete', function(done) {
+    var this_ = this;


@barbogast It's not necessary to use the new package. As @phated said, this test case can be skipped by the following code at this point:

it('should return error code 1 if any tasks did not complete', function(done) { if (!('exitCode' in process)) { // On v0.10 only, this condition is true because process doesn't have .exitCode. this.skip(); return; // This is not necessary because skip() throws an exception, but is recommened to avoid confusing. } ...

Are you sure this will work? I just rechecked and

> 'exitCode' in process false

for

node -v v8.9.3

So even on nodejs > 0.11.0 the exitCode property is not set by default.

Or am I misunderstanding completely?

Ah, I think I understood. Do you mean that exitCode was set already by process.exitCode = 1 in sync-task.js? This would work, but only if require('gulp-test-tools').gulpRunner which is used by the test doesn't spawn a new process, right? I guess that it does but I'll try when I get home.

@barbogast I'm sorry, I really misunderstood. You are right. I did only checked process.exitCode is undefined on v0.10 and I completely thought process.exitCode is zero initially on other versions.

@barbogast Since these test cases in test/lib/sync-task.js are not unit test, please move this file to test/ and rename it to another like exit-code.js.

In addition, I think it's better that these two cases can be put into one case and then nodeDoesNotNodeSupportExitCode() is used not for this.skip() but for unchecking exit code.

Please move the file like sttk mentioned and remove that utility (using my other recommendation above).

Do we need 2 non-completing tasks?

I created 2 tasks to also test that the log message is rendered correctly with multiple non-completing tasks. Should I remove the second task?

That's fine. I'm not partial either way.

barbogast · 2018-01-22T20:20:09Z

Thank you for your review. 👍

The new dependency and the utility function are removed.

Note that in addition to a test for the exit code I added a test for the log message about the non-completing tests. I couldn't find any tests for sync-tasks.js so I went ahead and added a second test case.

The reason I created 2 test cases is that test case for the log message can run under nodejs 0.10 and should be reported as successful while the second test case is then reported as skipped. Should I join them anyway?

The test file is moved to the test-directory. I have not yet renamed the test file since it not only tests the exit code but also the log message for non-completing tests. So I think the name exit-code.js is not fitting. Maybe non-completing-tasks.js?

phated · 2018-01-22T20:37:25Z

non-completing-tasks.js sounds great!

barbogast · 2018-01-22T20:42:30Z

all right, I'll rename it

Great, thanks a lot for your reviews, @phated @sttk

Should I sqash the commits before merging?

Nah, I'll do that in the merge.
