1352777 - Clicking on dropmarkers in JSON viewer doesn't collapse long string values

Status: VERIFIED FIXED

(DevTools :: JSON Viewer, defect, P3)

Description

[684sigma]

Attachment: example of JSON file, by reporter.json

I have a problem with Firefox Beta 53. It also happens in Nightly 55. Doesn't happen in Beta 52, ESR 45 (if JSON viewer is enabled from about:config).
Clicking on dropmarkers in JSON viewer doesn't collapse long string values. Here's how to reproduce it:

1. Open attached json file in a new tab
2. Click on dropmarker near a long string's property name.

Result: dropmarkers have no effect
Expected: dropmarkers should collapse/expand the string

Thanks for reporting!

Collapsed button is not so easy to pay attention but it is definitely an existing issue.

[Liz Henry (:lizzard) (relman/hg->git project)]

It is late in beta to take a fix here but we could still potentially take a patch for aurora 54.

HI,i would like to work on this bug.Could you guide me on this?

Sure!  The regression is caused by this patch https://reviewboard.mozilla.org/r/102066/diff/4#index_header. So you probably want to look through the changes and find out root cause where triggers this regression.

Attachment: modified TreeCell so that the component updates also on 'open' change state

Hi,

From what I understand, the TreeCell component should also update when the row's "open" state is updated, which basically happens when LabelCell is toggled.

Adding an extra check for that state on shouldComponentUpdate in tree-cell.js seems to fix the problem and doesn't seem to break any related tests locally in /devtools.

Hey Matt, thanks for the work!

I guess there are something wrong when submitting patch. I know bugzilla is old and somewhat hard to understand how to use. You can check the "patch" checkbox in "Create New Attachment" when uploading your patch, and then I can start reviewing your patch on bugzilla old review board.

Or how about setup new mozreview [1] (example [2]) to push your patch. It's document very well and pretty convenient. If you have any question, feel free to ask me:)

Oh sorry, I thought I had to request feedback first as I saw here: https://developer.mozilla.org/en-US/docs/Tools/Contributing#Asking_for_feedback

Just created review the request. I suppose I don't have the permissions to trigger try builds yet?

Please fix above two open issues on mozreview and mark them as fixed. You can also trigger a Try Build on our CI testing. Once Try tests are green, you can add a "checkin-needed" keyword in bugzilla field. Release engineer will do the rest for us to merge your commit to mozilla-central thunk branch. And then you will see your fix in Firefox Nightly.

Fixed commit message + removed whitespace

Comment 14

[Matt R [:stylizit] (slow, away until Sep)]

Thanks for the explanations!

It seems I cannot trigger a Try Build because of permissions. 
I have filed a bug as per: https://www.mozilla.org/en-US/about/governance/policies/commit/ 

I hope that's the correct way to do it. Would you be so kind to vouch for me?

Vouch!

Nice! so far you've done very well. I've pushed try and let's wait and see.

> I've pushed try and let's wait and see.

I'm a bit confused, the reviewboard says:
2 jobs testfailed, 63 jobs success

However when I expand all jobs, all tests seem to be green on treeherder. Is that a bug? An intermittent failure?

Comment 17

[Matt R [:stylizit] (slow, away until Sep)]

Oh, I just realized it's "mochitest clipboard" from the excluded jobs list timing out.

I guess it's unrelated and an occurence of an intermittent failure and we should be good to go?

Comment 18

[Ricky Chien [:rickychien] (inactive)]

Yep, you're right. There are some problems in mochitest clipboard jobs so that release engineer (releng) mark them as excluded jobs. I think they are irrelevant failures and it's ready to go.

btw, I haven't enabled every email notification when getting reply, so feel free to set "Need more information from" flag to me.
