Problem: The command "rake db:create:all" crashes

Hi All,

I'm running: Rails 2.3.5 MySQL 5.1.44 WindowsXP-Pro/SP3

Following Noel Rappin's book, Pro RoR, I successfully got past the point of creating my first scaffold: ruby script/generate scaffold supplier nickname:string qbname:string That produced the migration, 20100221011210_create_suppliers.rb: class CreateSuppliers < ActiveRecord::Migration   def self.up     create_table :suppliers do |t|       t.string :nickname       t.string :qbname

      t.timestamps     end   end

  def self.down     drop_table :suppliers   end end

Then I ran "rake db:create:all". The Command Window display for this is:

K:\_Projects\Ruby\_Rails_Apps\_EIMS\RTS>rake db:create:all (in K:/_Projects/Ruby/_Rails_Apps/_EIMS/RTS) K:/_Utilities/ruby186-26_rc2/ruby/lib/ruby/gems/1.8/gems/ activesupport-2.3.5/lib/active_support/core_ext/module/ introspection.rb:73: [BUG] Segmentation fault ruby 1.8.6 (2007-09-24) [i386-mswin32]

This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information.

K:\_Projects\Ruby\_Rails_Apps\_EIMS\RTS>

Then I checked for generated databases with:

show databases;

Among several tables, it showed only one of my RTS app's expected databases: rts_development. My database.yaml specifies the normal 3: development, test and production

Further, I tested whether this database had the specified table "supplier":

show tables in rts_development;

Empty set (0.00 sec)

Then I tested whether I could drop the RTS database:

drop database if exists rts_development;

Query OK, 0 rows affected (0.01 sec)

All the logs in RTS\log are empty except for development.log. But as far as I can tell, all that data was written a couple of days ago when I had an older edition of MySQL and gave me crashes.

Any ideas on how to proceed. I've tested my current version of MySQL with a number of commands in the MySQL monitor in a Windows Command Window and seems to perform well.

Any ideas?

Thanks in Advance,Richard

I know there are some issues with RoR and MySQL 5.1 on windows, at least for Vista x64 and Win7 x64. I dont know if there's a bug with the adapter or if its mysql itself. I suggest you try version 5.0.

Hi Sharagoz,

I suggest you try version 5.0.

5.0 was working well for years on my WinXP machine. I thought that since I had a bad installation for the purpose rake db:create:all, I outgh to get the latest release of MySQL. But that extra step might have been unwise.

Thanks for the suggestion. Richard
