[Vtigercrm-developers] bug fixes that will require a Migration script

[Alan Bell]

Hi,
I have a branch here 
http://code.vtiger.com/alanbell/vtigercrm/tree/secure_portal_passwords 
which contains this change 
http://code.vtiger.com/alanbell/vtigercrm/tree/secure_portal_passwords
which should provide encrypted passwords for the customer portal. It 
does require the user_password column in the vtiger_portalinfo table to 
be a bit longer than it is at the moment, varchar(30) is not enough to 
store a hashed password, varchar(128) is OK. How should I propose this 
schema change? modules/Migration/schema/640_to_650.php doesn't exist yet.

On a related note, I think it would be good if *everything* in the 
migration files would always be safe to repeat. Anything that inserts 
stuff should first check to see if it is already there, anything that 
transforms things should check to see if they have already been 
transformed, if doing it twice would be harmful. Often a migration 
script fails somewhere due to a change in a specific instance, I fix the 
problem and run the migration script again and all the previous steps 
that were OK now cause havoc!

Alan.
