Re: Upgraded from 1.9.3 to 1.13.0- got error:Illegalmix of collations

Hi Jim, thanks. There were some problems during installation but it did go through. Since I was able to change the table structures by hand, I assumed the script could have done the same but did not. In my next upgrade, I will take notes and compare the schemas and then get back here if I notice differences.
thanks!
Eric

Assuming Alternative 2 works as advertised, check that permissions are set
properly and that it ran completely. I've always used the commandline
method so I'm not familiar with Alternative 2.
Also, consider that an extension that is working with the old schema needs to
be upgraded.
And if you have commandline access, try running update.php from the
commandline.
If that fails you may want to start from scratch and do the upgrade again from
backups.

That might be it but, the directions dont ask me to run those scripts
separately, as far as I can see?
http://www.mediawiki.org/wiki/Manual:Upgrading_MediaWiki
I followed the Alternative 2, which just asked me to re-run the installer. In
that, it says:
- "When the installation process starts, the script will detect existing
MediaWiki tables, and upgrade their schema."

After upgrading the Mediawiki code did you run:
maintenance/update.php
and
maintenance/refreshLinks.php
?

Here's what I found. When Mediawiki upgrades, it doesnt seem to care to
update the table schemes properly. Here's a sample of what I found:
Old table row specs, for mw_image (this is after the upgrade has been applied
from 1.9.3 to 1.13.0):
img_size int(8)
img_width int(5)
img_height int(5)
New table row specs for the same table, mw_image (for a brand new 1.13.0
installation):
img_size int(10)
img_width int(11)
img_height int(11)
The field sizes are different as you can see. New tables have bigger fields but
the old ones still contain short fields after the upgrade is applied.This is
just an example. The bug that I was getting (illegal mix of collations), was
fixed due to the Collation fields being different in the cases for an upgraded
MW and a new MW. I also noticed differences in all the other fields as well
(Default, Type, Binary, Attributes) for tables rows. Sometimes the differences
were significant. Here are some real examples:
- length of data field doubled for example, int(5) to int (10)
- the Type changed in an upgraded version from "varbinary(255)" to
"blob", in a new installation
Usually, Collate was empty for a brand new 1.13.0, while it was latin_bin or
latin1_swedish_ci for an upgraded version.
There must be important reasons why changes were made to the rows as versions
progressed.
So i guess this is something that should be fixed for upgrading? That means,
when an upgrade is being applied, it should update all the row data for each
table as well.

Everything works on my wiki, except when I view the logs for a page, I get this
error:
A database query syntax error has occurred. This may indicate a bug in the
software. The last attempted database query was:
(SQL query hidden)
from within function "LinkCache::addLinkObj". MySQL returned error
"1267: Illegal mix of collations (latin1_bin,IMPLICIT) and
(utf8_general_ci,COERCIBLE) for operation '=' (localhost)".
Any ideas on how to fix this? I can go into myPhPAdmin and manipulate tables if
needed.
thanks
Eric
