Contributions Calendar stopped working when upgraded 7.9.4 to 7.10.0

Hi

I have updated my gitlab on 2 of my instances, personal and corporate. The calendar in the personal implementation is working without any problems. Whereas the corporate one no longer works. Below is my environment

# bundle exec rake gitlab:env:info RAILS_ENV=production
(in /var/lib/git/gitlab)

here is an image of the commits calendar that I get on the corporate one, I selected 19th September an example, which shows that there were 3 commits, but if you hover over 19th September it says there is nothing

I have the same problem for the git repositories I have imported.

Have the same issue.

I even sniffed MySQL and the query correctly returns contributions for particular user:

mysql> SELECT date(created_at), count(id) as total_amount FROM `events`  WHERE (`events`.`author_id` IS NOT NULL) AND (action = 5 OR (target_type in ('MergeRequest','Issue') AND action in (1,3,7))) AND `events`.`author_id` = 13 AND (created_at > '2014-04-23 00:48:13') AND `events`.`project_id` IN (92, 88, 84, 45) GROUP BY date(created_at);

+------------------+--------------+
| date(created_at) | total_amount |
+------------------+--------------+
| 2014-11-22       |            2 |
| 2014-11-27       |            4 |
| 2014-11-28       |            4 |
| 2014-12-30       |            1 |
| 2015-01-06       |            4 |
....

Still in the /calendar ajax request all the timestamps are zeros:

<div class='calendar' id='cal-heatmap'>
<script>
  new Calendar(
    {"1398200400":0,"1398286800":0,"1398373200":0, ...

That's also reported on GitHub: https://github.com/gitlabhq/gitlabhq/issues/9175

Maybe this can be fixed by https://github.com/gitlabhq/gitlabhq/issues/9186

Status changed to closed

Fixed on master. Close it here
