Hi Marc,
I identified seven situations where the method
PMA_sendResponseForNoResultsReturned runs.
1-> When browsing an empty table
2-> When executing a query on a non empty table which returns zero results
3-> When executing a query on an empty table
4-> When executing an INSERT, UPDATE, DELETE query from the SQL tab
5-> When deleting a row from BROWSE tab
6-> When searching using the SEARCH tab which returns zero results
7-> When changing the structure of the table except change operation
In the first case the $goto variable is not initialized. But in the second,
third and fourth cases it is initialized to tbl_sql.php.
In the third, fourth and fifth cases the $goto variable is initialized with
sql.php itself with certain other url parameters.
In the 7 th case $goto variable is set to $tbl_structure.php
But I identified all these cases send Ajax responses where $goto variable
or sending header location were never used. I would like to know whether my
test scenarios are comprehensive if so shall I remove the redundant code
segments.
