ISSUE: https://github.com/FirebirdSQL/firebird/issues/7545
|
|
TITLE: Server crash on some LockMemSize values
|
|
DESCRIPTION:
|
|
NOTES:
|
|
[14.04.2023] pzotov
|
|
1. One need to be sure that firebird.conf does NOT contain DatabaseAccess = None.
|
|
2. Test uses pre-created databases.conf which has alias defined by variable REQUIRED_ALIAS.
|
|
Database file for that alias must NOT exist in the QA_root/files/qa/ subdirectory: it will be created here.
|
|
Content of databases.conf must be taken from $QA_ROOT/files/qa-databases.conf (one need to replace
|
|
it before every test session).
|
|
Discussed with pcisar, letters since 30-may-2022 13:48, subject:
|
|
"new qa, core_4964_test.py: strange outcome when use... shutil.copy() // comparing to shutil.copy2()"
|
|
3. Value of REQUIRED_ALIAS must be EXACTLY the same as alias specified in the pre-created databases.conf
|
|
(for LINUX this equality is case-sensitive, even when aliases are compared!)
|
|
|
|
Confirmed crash on 5.0.0.1010, 4.0.3.2923, 3.0.11.33674
|
|
Checked on 5.0.0.1014, 4.0.3.2929
