User Story

To get started please check the following documentations:


(2 files, 3 obsolete files)

The method `ProcessHandler.waitForFinish()` doesn't seem to be used across the tree anymore. As such it can be removed. It can be found here:

When removed please run all the mozbase unit tests with `mach test testing/mozbase`. Once the patch is uploaded I will trigger a try build to test all other existing test jobs.
Priority: -- → P3

I would like to work on this bug as my first open source contribution. I went through the two documentations listed and installed Mercurial on my system. I could not install MozReview as I don't have the access privileges. Could you please guide me further so that I can get started?

Hello Anuja, you are welcome to work on this bug. In regards of mozreview, if you refer to the more privileged features when having an LDAP account this is not necessary. The only feature you need is to upload patches and this should work fine once you setup the Bugzilla API key.

Hi Henrik,
Thank you! I am working on cloning mozilla-central and making the changes you suggested. Can I be assigned this bug?
As by our procedure I will assign you when the patch has been uploaded. Thanks for working on it.

As no one has uploaded a patch for the last 9 days, I've added a patch here. However, after I ran `mach test testing/mozbase` the `test_process_stop_via_multiple_threads[firefox]` test failed.

Akshay, that is fine. Thanks. Can you please tell me what exactly is failing? I don't see that this test is using this method we are about to remove via this bug.
Attached file test_results
You're right in that the this test doesn't use the removed method, and it fails on line 35, `assert returncode not in [None, 0]`. I've attached my test results here.
Akshay, maybe this problem is only relate to your machine. I would kinda like to run the automated tests in CI with your patch attached. Would you mind to push the patch to mozreview instead of just uploading an attachment? That would help me a lot. Details about that can be found here:

Thank you. I pushed a try build:

Bug 1465046 - Remove ProcessHandler.waitForFinish().

So I checked the try build results. And as it looks like there is still a test which uses this method. You will have to update the test.

It can be found here:

I've updated the test to remove the deprecated function call so it calls wait() instead of waitForFinish().
Akshay, can you please use `hg histedit` to squash both commits into a single one? For this change there shouldn't be multiple commits. Thanks.

Remove ProcessHandler.waitForFinish()

Usually a new push should update the existing mozreview patch, and not create a new one. But lets mark this old patch as obsolete now.

Sorry! I'll keep that in mind for future patches.

r=me with the commit message fixed. See inline comments for details.

Ok, here is the reason why a new mozreview has been created. You left in the commit message from the other commit, which then most likely created a new one for the first commit. Please remove everything after (including) the stars.

Also for the future I would propose that you don't add `r=whimboo` in the patch directly, but set it in mozreview directly.

is this bug still open ?
Akshay, as it looks like you missed to just update the commit message, and to push the patch again. Can you please do it so we can get your patch landed? If you aren't able to please let us know. Thanks.

Given that we haven't heard from Akshay, I will just do the update of the commit message myself and land the patch.
