Description:
The Windows configuration wizard allows for changes to the Innodb tablespace settings
during a re-configure, but I don't think this should be allowed.
When upgrading a version of the server (say 5.1.31 -> 5.1.35 <as tested>), during the
configuration of the upgraded server, the Innodb tablespace settings are greyed out and
the user must manually select Modify to change them.
This results in a warning being presented that the user must manually move / copy
existing files from the current location to the new one.
It seems that such a thing should also occur during a reconfigure of the server - the
user should be warned that a change in tablespace settings require manual file movement
to ensure continued operation of Innodb tables.
How to repeat:
To observer update behavior:
1) Install a version of the server and configure it.
2) Install an upgrade of the same server version (5.1.31 -> 5.1.35)
3) Observer during the configuration of the new server that the Innodb settings are
greyed out and the user must use a 'Modify' button to alter them. Choosing 'Modify' will
result in the presentation of a warning prompt.
To observe re-configure behavior:
1) Install a version of the server and configure it.
2) Re-configure it and observe that the Innodb settings are able to be changed without
presenting a warning, etc.
Suggested fix:
It seems that any change in Innodb tablespace settings should result in a warning to the
user so that they can either choose to abort the change or make the manual changes needed
to ensure that Innodb tables continue to work with the changes.
