diabling InnoDB in the MySQL Administrator causes an entry


in the config file /etc/mysql/my.cnf

This causes the error:

 /usr/sbin/mysqld: ambiguous option '--innodb=0'

while starting mysqld.

How to repeat:

Right option in the config file should be

Which server version are you using? Anything above MySQL 4.0.2 should understand the syntax innodb=0.

I'm using 4.1.1a, Administrator 1.0.3 and after disabling innodb I got the following:

mysql: ERROR: unknown variable 'innodb=0'

Hi Jorge, 
Maybe you are using a binary where innodb-support is not compiled in?
Otherwise it should work - I have no problems on my computer with the same server version(4.1.1-alpha-standard)

Hi Ulli

Sorry, I made a mistake in my previous email.  This bug happens in 4.0.18.

Im going to change its status back to Verified and pllease keep it that way until its fixed.

I *Do*  have InnoDB enabled and its working perfectly and even if InnoDB wasn't enabled this would still be a bug because once the changes are made to my.cnf everything else stops working while complaining about an erroneous my.cnf option.

An easy fix for this is the following:

replace the my.cnf line:

--innodb=0 will work in MySQL 4.1.x (as will
similar options like --bdb=0 and --isam=0),
because they are treated as GET_BOOL options.
However, that's a 4.1 change.  In 4.0.x, this
will not work, because these options are not
handled as boolean options. Thus, only the
--skip-xxx forms work, and not the --xxx=0
forms. This means that MySQL Administrator
*must* write the --skip-xxx forms for servers
in the 4.0 series. It's probably safest just to
use that form always, because it works in
both 4.0.x and 4.1.x.

Hi Jorge,

You are right. I have tested it with a 4.0 server and experienced the same problem now.

according to the manual :) GET_BOOL support was added in 4.0.2 and this is also true. The problem is that in the mysql 4.0 source the option has not been declared as GET_BOOL.
