ISSUE: 5362
|
|
TITLE: Regression. Triger on DISCONNECT with dynamic SQL (ES 'insert into ...'):
|
|
1) does not work in 3.0; 2) leads FB to crash when it is recreated
|
|
DESCRIPTION:
|
|
Test does following:
|
|
* obtains firebird.log as it was _before_ actions;
|
|
* stores initial script for creation DB objects in file <f_sql_init> for futher applying it twice (see ticket);
|
|
* open PIPE object and communicates with ISQL issuing commands into STDIN, three times; result is stored in var.'sqlres'
|
|
* print variable 'sqlres'; it content must be equal to that we get in FB 2.5;
|
|
* again apply initial DDL and then - one again launch ISQL with passing to it commands via STDIN and saving result in 'sqlres'
|
|
* print variable 'sqlres';
|
|
* obtains firebird.log as it is _after_ actions;
|
|
* compare two firebird.log versions - diff must be empty.
