ISSUE: 2625
|
|
TITLE: Add support for -nodbtriggers switch in gbak into services API
|
|
DESCRIPTION:
|
|
We add two database triggers (on connect and on disconnect) and make them do real work only when
|
|
new attachment will be established (see trick with rdb$get_context('USER_SESSION', 'INIT_STATE') ).
|
|
After finish backup we restore database and check that there is no records in 'log' table.
|
|
(if option 'bkp_no_triggers' will be omitted then two records will be in that table).
|
|
JIRA: CORE-2197
|
|
FBTEST: bugs.core_2197
|
|
NOTES:
|
|
[25.11.2023] pzotov
|
|
Writing code requires more care since 6.0.0.150: ISQL does not allow specifying duplicate delimiters without any statements between them (two semicolon, two carets etc).
