Description

I've been using redmine for a while now, but a few weeks ago the changesets stopped importing from git. When I run Repository.fetch_changesets, I get this error:

ActiveRecord::StatementInvalid: Mysql::Error: Column 'changeset_id' cannot be null: INSERT INTO changes (`changeset_id`, `action`, `revision`, `branch`, `from_path`, `from_revision`, `path`) VALUES(NULL, 'M', NULL, NULL, NULL, NULL, 'config/aaf.rb')

I get the same problem here, it suddenly started to happen today, without notice. It was working perfectly an hour ago and now poof, I get the same exception.

  • MySQL 4.1.22
  • Ruby 1.8.7 (2008-08-11 patchlevel 72) [powerpc-darwin8]
  • Rails 2.0.2
  • Redmine r1557

Still occuring after upgrading to:
  • Rails 2.1
  • Redmine r1769
Actions #5

I was able to get around this by deleting all the existing Changesets and then re-importing them:

script/runner 'Changeset.destroy_all; Repository.fetch_changesets'

Yes, deleting changesets and re-importing them work, that's what I did too. But the bug can reappear after a while. It did for me yesterday...

Actions #7

Git does not return the commits in chronological order.

So this bug is initiated by the sort order of the has_many :changesets association in the repository model.
This ordering affects the result of repository#latest_changeset which will be given to git_adapter#revisions as the identifier_from parameter. Thus the changesets fetched from git might contain changesets, that have been created in the redmine database before.

The fix we applied is:

in repository.rb:

+ has_many :changesets, :dependent => :destroy, :order => "#{Changeset.table_name}.committed_on DESC, #{Changeset.table_name}.id DESC" 
- has_many :changesets, :dependent => :destroy, :order => "#{Changeset.table_name}.id DESC" 

And it seems to work fine so far. (No need to delete all changesets and reimport them.)

Another solution to the above problem would be to override repository#latest_changeset within the git.rb, so only git will be influenced by that fix.

  # in git.rb:
  def latest_changeset
    changesets.find(:first, :order => "#{Changeset.table_name}.id DESC")
  end

A quick correction: in #note-7 the '+' and '-' signs of the diff are permuted. It should be

- has_many :changesets, :dependent => :destroy, :order => "#{Changeset.table_name}.committed_on DESC, #{Changeset.table_name}.id DESC" 
+ has_many :changesets, :dependent => :destroy, :order => "#{Changeset.table_name}.id DESC"

r1953 should fix this problem. It now checks that the changeset is not in the database before inserting it.
I prefer not to rely on the order in which git returns the changesets.
