[Phpmyadmin-devel] slave replication, load data from master

[Tomas Srnka]

If I use code from db_operations, I will have to adjust the code from 
db_operations (which should not be difficult), but I will also have to 
modify PMA_Table::moveCopy a lot, because they are using methods of 
$GLOBALS['pma']. What is good about PMA_Table::moveCopy is that it will 
also copy views, however it won't copy triggers for me.

That's why, I'm still playing with idea of using Zahraa's code for 
synchronization databases - the code is already prepared for multiple 
servers and I think it will provide what I need - simple copy structure 
and/or data from one server to another. Unfortunately, the last code 
from Zahraa, which I found is from midterm. Zahraa - could you please 
update your SVN repositary?

Modifying existing code will allow me to use a bit more complex copy 
tool, but I'm not really sure, if it is possible to modify the code in a 
way, that it can work with external/another mysql server. In all cases, 
the best way to copy data from master to slave would be by using 
mysqldump command.

Any suggestions about loading data from master to slave before 
replication is started are more than welcomed.

Thank you.

Best Regads,

Tomas
