ISSUE: https://github.com/FirebirdSQL/firebird/commit/333be4bfd48d8b2f84852073436a20698dbc8c54
|
|
TITLE: Change error by warning in the case when isc_dpb_parallel_workers value is not at valid range
|
|
DESCRIPTION:
|
|
Test creates backup and tries to restore it using gbak utility (with '-v' switch).
|
|
Three iterations is performed with restore:
|
|
* via local (embedded) protocol;
|
|
* via remote protocol without using Services API;
|
|
* via remote protocol WITH usage Services API (i.e. with '-se' command switch);
|
|
Actual value of MaxParallelWorkers is evaluated by querying to RDB$CONFIG table.
|
|
We add 1 to this value and pass it to gbak '-par' option. Output of gbak is redirected to log.
|
|
This log must contain 'gbak: WARNING:' message and must NOT have 'gbak: ERROR:' ones.
|
|
NOTES:
