Description

Hello,
I have a Remidne 4.1 installation with about 100 issue statuses.

When I visit workflow edit page and unset "Only display statuses that are used by this tracker" checkbox, if I press "edit" button browser hangs.

I reproduced this also with a "fresh" installation.

I attached a docker-compose file by which I created the "fresh" installation.

Once the sistem is up, I created issue statuses by following these steps:

$ docker-compose up
$ docker-compose exec redmine bash
> cd /opt/bitnami/redmine
> bundle exec rails console -e production
irb(main):001:0> (1..100).each { |i| IssueStatus.create(name: "issue status: #{i}") }

And then visit the workflow page.

Thank you.


This is my environment:

I found the issue.

The problem is inside:

public/javascripts/application.js

inside this function:

$(function () {
    $('[title]').tooltip({
        show: {
          delay: 400
        },
        position: {
          my: "center bottom-5",
          at: "center top" 
        }
    });
});

If I count the title attributes in the page with 100 issue statuses, I have 34454 items.

When I remove this code, the page loads correctly.

However I do not know the right way to fix it.

Hope this can help the fix.

As a workaround at the moment I changed the line:

    $('[title]').tooltip({

with this:

    $("body:not('.controller-workflows.action-edit') [title]").tooltip({

It disables redmine tooltip on that page.
However browser still renders tooltip with its default behaviuor.

The attached patch changes the tooltip selector in order to ignore elements with class no-tooltip and add this class to all cells from workflow status transitions tab.

What else we can do is to add this class only when there are more than x transitions.

andrea andrea Valle, can you test this solution and tell me if works for you?

Thank you for posting the patch but I found that the patch breaks an existing test.

Applying the following patch before/after disable_tooltip_in_workflow_status_transition.patch fixes the error.

I have confirmed the problem with 100 statuses. After applying the patch, Chrome finishes loading the page in 20 seconds and does not display "Page unresponsive" dialog box.

I will commit #34247#note-7 and disable_tooltip_in_workflow_status_transition.patch soon.
