Hi,

I just tried to update our mahare installation to 1.2 by making a copy to XAMP. Unfortunately the update isn't running through smoothly. While updating the database I get the following error:

 

 :( Could not execute command: ALTER TABLE "mahara_artefact_blog_blogpost_file" RENAME TO "mahara_artefact_attachment"

Call stack (most recent first):
  • execute_sql("ALTER TABLE {artefact_blog_blogpost_file} RENAME T...") at C:\Users\Alex\Desktop\xampp\htdocs\collabuni\lib\db\upgrade.php:909
  • xmldb_core_upgrade("2009022614") at C:\Users\Alex\Desktop\xampp\htdocs\collabuni\lib\upgrade.php:297
  • upgrade_core(object(stdClass)) at C:\Users\Alex\Desktop\xampp\htdocs\collabuni\admin\upgrade.json.php:93
 
 
I need to work on a local copy of the mahara code to be able to reapply a number of customizations (mainly work on theme and a few changes in the navigation we applied after some usability testing). I heard about you guys keeping the code in a git repository to track changes. Is it difficult to set up an own repository? This would be way easier than documenting all changes in a Wiki. Unfortunately the mahara support articles introducing "git" aren't complete yet.
 
Any help or suggestions are appreciated!
Alex

Ah sorry empty tables weren't included in my import to my local installation. ALTER TABLE was succesfull. Unfortunately now I get:

 

:( Could not execute command: CREATE TABLE mahara_import_event_subscription ( id BIGINT(10) unsigned NOT NULL auto_increment, plugin VARCHAR(255) NOT NULL, event VARCHAR(50) NOT NULL, callfunction VARCHAR(255) NOT NULL, CONSTRAINT PRIMARY KEY (id), CONSTRAINT mahara_impoevensubs_plu_fk FOREIGN KEY (plugin) REFERENCES mahara_import_installed (name), CONSTRAINT mahara_impoevensubs_eve_fk FOREIGN KEY (event) REFERENCES mahara_event_type (name), CONSTRAINT mahara_impoevensubs_pluevec_uk UNIQUE (plugin, event, callfunction) )ENGINE=innodb

Call stack (most recent first):
  • execute_sql("CREATE TABLE mahara_import_event_subscription ( ...", true) at C:\Users\Alex\Desktop\xampp\htdocs\collabuni\lib\dml.php:1368

Hi Alex,

Can you paste that CREATE TABLE statement directly into MySQL and see what the error message is?

About your other question, yes we do use git. If you visit http://git.mahara.org/ there are basic instructions for how to clone our repository.  There's also http://wiki.mahara.org/Developer_Area/Getting_Code_from_Git which as you say, isn't very complete.  However, it's enough for someone familiar with git, so I guess maybe other than that you'd be best to read up on how to use git ;)  There are heaps of very good tutorials out there.  If you're already familiar with cvs or subversion you probably have quite a lot to "unlearn" though.

If you want to start using git and run into trouble, come to our irc channel #mahara on freenode, and someone might be able to help.

Hi Penny,

spent the day reading on subversion and git. It's definetly worth looking into and I already found a pretty good introduction.

Mysql error message:

#1005 - Can't create table 'social.mahara_import_event_subscription' (errno: 150)

 

thx Alex

Argh, I have no idea how to make mysql be more verbose than that, error 150 seems to be a foreign key violation, but I can't see what the problem is.

What version of mysql do you have?

It's MySQL 5.1.37

Does that help? :(

You have the same problem that some other folks have in this thread: http://mahara.org/interaction/forum/topic.php?id=1228
