Redmine

There was a problem in trunk with MySQL that should have been corrected by a subsequent revision. What exact svn revision and MySQL version are you using?

forgot the mysql version, server mysql version 5.0.67

after getting revision 3854 from svn and running the db migration again, the error still exists.

many regards,
kpw

This is odd...

The migration was created in r3828 and changed in r3830 to please MySQL. The fix then worked for all developers that tested it. It removes the default value for the column. Unless your mysql adapter does something strange, the error you observed should be seen on a fully updated system.

Please mak sure, the content of your db/migrate/20100705164950_change_changes_path_length_limit.rb is exactly the same as this one: source:trunk/db/migrate/20100705164950_change_changes_path_length_limit.rb

If (and only if) this is the case, you could try to add :default => nil to line 3. But as I said, this should really not be needed, as the current version of the migration works good for many people.

I have the same problem.
File 20100705164950_change_changes_path_length_limit.rb is the same from trunk
I'm updating from Redmine 0.8 to 1.0 (1.0.0 (RC) (2010-07-18))

May be it halps: At the start of my migration I had problem with plugin http://www.redmine.org/boards/3/topics/4701 . But I solved it install modif. plugin http://www.redmine.org/boards/3/topics/4701#message-14933

How can I do?

And I try to modify 20100705164950_change_changes_path_length_limit.rb like Holger say:

class ChangeChangesPathLengthLimit < ActiveRecord::Migration
  def self.up
    change_column :changes, :path, :text, :null => false, :default => nil
    change_column :changes, :from_path, :text
  end

  def self.down
    change_column :changes, :path, :string, :default => "", :null => false
    change_column :changes, :from_path, :string
  end
end

Sorry for my english and my not deep knowledge of Redmine's insides

Evgeny, please tell us which version of MySQL you are using. It seems, Rails ActiveRecord does not fully follow its own standard of not allowing a default value of text columns on mysql...

Could you try to change the migration to the following:

class ChangeChangesPathLengthLimit < ActiveRecord::Migration
  def self.up
    change_column :changes, :path, :text
    change_column :changes, :from_path, :text
  end

  def self.down
    change_column :changes, :path, :string, :default => "", :null => false
    change_column :changes, :from_path, :string
  end
end

With this change, there are no DB constraints on the path column anymore. This should please even the most stubborn MySQL. It should also be enough to enforce db consistency as it is checked in the model class.

If there are any errors, please post a full description here.

Hi Holger,

i have exactly the same problem while db-migrating to version 1.0.0 and followed your instructions, but still the same error occurs (see below).

F:\redmine\vendor\plugins>

P.S. "rake db:migrate RAILS_ENV=production" is still not working

Evgeny, please follow RedmineUpgrade, especially Step 4. You need to run

rake db:migrate_plugins RAILS_ENV=production

before your rake db:migrate. Also make sure to have a proper database backup before running any migrations.

Felix, please try the change I proposed above. If it still does not work, we need to come up with a more invasive change...

Evgeny, sorry, missed a bit. The commands would be:

rake db:migrate:upgrade_plugin_migrations RAILS_ENV=production 
rake db:migrate_plugins RAILS_ENV=production 

The first command is the important one.

Holger, sorry, last time I posted wrong log. this is right:

F:\redmine>

Hey,

it worked for me now.
It seemed, that none of the changes affected anything...
so i commented the first few lines of the file 20100705164950_change_changes_path_length_limit.rb, just to see what happens.
Then migration run throuhg without errors.
Afterward i put back the lines, and from then on it worked...

the file now looks like this:

class ChangeChangesPathLengthLimit < ActiveRecord::Migration
  def self.up
    change_column :changes, :path, :text, :null => false
    change_column :changes, :from_path, :text
  end

  def self.down
    change_column :changes, :path, :string, :default => "", :null => false
    change_column :changes, :from_path, :string
  end
end

Regards
Felix

Felix, each migration is only run once. So if it ran successfully, it is never run again. As you said, you commented the first line, the migration did not fully run and you now might have a mismatch between actual schema and expected schema. Make sure the columns path and from_path in the changes table are actually of type text in your db.

Okay, so I just spent about three hours of my time to setup Windows, Mysql and Redmine on it. Executive summary is: Can't reproduce.

• I setup a WAMP server on Windows 7 with MySQL 5.0.88 and Ruby 1.8.7
• Then I installed a fresh Redmine 0.8, created a project and imported the Redmine subversion repository.
• After that, I upgraded the install to Redmine 1.0 following RedmineUpgrade.

All of these steps went flawlessly. So I can safely say: The migration works even on MySQL 5 on Windows.

getting a fresh redmine version from svn, comparing it with the version i used before, and found NO differences in any file, except the svn entries.

now running the migration again and the error still exists.

now after creating a new database ( redmine_test ) and running the db migration on the new database, i get these messages:

c:\RailsApplication\redmine3>rake db:migrate RAILS_ENV=test
(in c:/RailsApplication/redminetest)
Missing these required gems:
  shoulda  ~> 2.10.3
  edavis10-object_daddy
  mocha

You're running:
  ruby 1.8.7.249 at c:/ruby/bin/ruby.exe
  rubygems 1.3.5 at C:/Users/kpw/.gem/ruby/1.8, c:/ruby/lib/ruby/gems/1.8

Run `rake gems:install` to install the missing gems.

Never seen this before, any ideas ?

many regards,
kpw

Hi Holger,

Thanks for your reply.
I went through the whole thing once more.
I copied my current Redmine-database to test Redmine 1.0.0
Migrating the DB stopped again at this file 20100705164950_change_changes_path_length_limit.rb

i tried three versions of this file:
1)

class ChangeChangesPathLengthLimit < ActiveRecord::Migration
  def self.up
    change_column :changes, :path, :text, :null => false
    change_column :changes, :from_path, :text
  end

  def self.down
    change_column :changes, :path, :string, :default => "", :null => false
    change_column :changes, :from_path, :string
  end
end

class ChangeChangesPathLengthLimit < ActiveRecord::Migration
  def self.up
    change_column :changes, :path, :text, :null => false, :default => nil
    change_column :changes, :from_path, :text
  end

  def self.down
    change_column :changes, :path, :string, :default => "", :null => false
    change_column :changes, :from_path, :string
  end
end

class ChangeChangesPathLengthLimit < ActiveRecord::Migration
  def self.up
    change_column :changes, :path, :text
    change_column :changes, :from_path, :text
  end

  def self.down
    change_column :changes, :path, :string, :default => "", :null => false
    change_column :changes, :from_path, :string
  end
end

i always get the same error:
Mysql::Error: BLOB/TEXT column 'path' can't have a default value: ALTER TABLE `changes` CHANGE `path` `path` text DEFAULT '' NOT NULL
(see trace-output above)[[http://www.redmine.org/boards/2/topics/15654#message-15698]]

again my setup:

C:\redmine_100>mysql --version
mysql Ver 14.12 Distrib 5.0.67, for Win32 (ia32)

C:\redmine_100>ruby script/about

Mysql::Error: BLOB/TEXT column 'path' can't have a default value: ALTER TABLE `changes` CHANGE `path` `path` text DEFAULT '' NOT NULL

Could you please all post what windows versions (XP, 2003, Vista, 7) you are using and if they are 32 or 64 bit? We are aware that mysql is a pain in the a.. is weird with defaults on text columns and are trying to reproduce the problem (Holger did at least) but didn't have any success with it.

Hello,

We run redmine one a Windows Server 2008 Web Edition SP2 with 32 bit. I hope this helps to reproduce the error...

Thanks and Regards
Felix
