Mixed up dates in contributors statistics graph

[sdinot]

For testing purpose:

• I created an empty repository (zoinx/zoinx-orekit.git) using Redmine Git Hosting interface

• I imported a third party repository (Orekit sources) :

  $ git clone http://www.orekit.org/git/orekit
  $ cd orekit
  $ git remote add myforge ssh://[email protected]/zoinx/zoinx-orekit.git
  $ git push myforge master

Dates are mixed up in the contributors statistics tab:

I think this is linked to http://www.redmine.org/issues/5357

The revision order in git is provided only by the linked list nature of revisions, i.e. a revision holds a reference to its parent revision, which in turn holds a reference to its parent, and so on.

I don't know if it can be easily fixed.

I've done the test and it seems to work:

Which version of Redmine are you running?

Hi Nicolas,

Thank you for investigating this issue.

I am not familiar with the database model of Redmine but what do you think about the following kind of query ?

SELECT c.commit_date AS date, COUNT(c.id) AS changes FROM changesets AS c JOIN repositories AS r ON c.repository_id = r.id JOIN users AS u ON c.user_id = u.id WHERE r.identifier = 'zoinx-orekit' AND u.mail = '[email protected]' GROUP BY c.commit_date ORDER BY c.commit_date DESC;

I think that I have found the problem. There are some missing ".order(:commit_date)" in the repository_patch.rb file:

I've tested your patch and it's still working for me :)
Does it work for you?

[sdinot]

Yes, my patch works for me.
I use PostgreSQL, do you use MySQL? If that is the case, maybe that MySQL returns ordered results when a GROUP BY clause is used but not PostgreSQL.

Maybe. That's very possible.
In all cases it will be in next release (v0.7.4) ;)

Thank you!
