@ -11,133 +11,87 @@ DESCRIPTION:
|
||||
Then we get content of firebird.log before disconnect and after.
|
||||
Finally we compare these logs and search in the difference lines about error message.
|
||||
FBTEST: functional.trigger.database.disconnect_01
|
||||
NOTES:
|
||||
[26.05.2022] pzotov
|
||||
Re-implemented for work in firebird-qa suite.
|
||||
ACHTUNG: firebird.log may contain NON-ASCII characters if localized Windows is used!
|
||||
Because of this, we have to add 'encoding=locale.getpreferredencoding()' to act.connect-server() call.
