The question is whether seeing legacy is really important. If not, I'd suggest to convert NULL into INVOKER during restore.

That is the part I was missing, thanks.
BTW in thread_db::reschedule() we have:
-
void thread_db::reschedule()
{
// Somebody has kindly offered to relinquish
// control so that somebody else may run
checkCancelState();
StableAttachmentPart::Sync* sync =
this->getAttachment()->getStable()->getSync();
Database* dbb = this->getDatabase();
if (sync->hasContention())
{
FB_UINT64 cnt = sync->getLockCounter();
EngineCheckout cout(this, FB_FUNCTION);
Thread::yield();
while (sync->hasContention() && (sync->getLockCounter() == cnt))
Thread::sleep(1);
}
checkCancelState();
Monitoring::checkState(this);
if (tdbb_quantum <= 0)
tdbb_quantum = (tdbb_flags & TDBB_sweeper) ? SWEEP_QUANTUM :
QUANTUM;
}
-
Should not the checkCancelState() be better inside the "if
(sync->hasContention())" as the no contention case just checked it?

Re: [Firebird-devel] Dropping database default SQL SECURITY
You say it cannot be NULL, yet you say the "initial NULL". Looks very inconsist to me. Now for INVOKER there's 2 possible values. Yet one can't ever be set by user. -- Mgr.

Re: [Firebird-devel] DROP SQL SECURITY for trigger
It's possible to alter a trigger partly, alter an option of a trigger. SQL SECURITY is one of such options. For procedures you must specify "complete definition" every time. пн, 14 февр. 2022 г. в 12:35, Jiří Činčura : > > Hi *, > > I'm wondering why is there explicit "DROP SQL SECURITY" for triggers, while > i.e. procedures use regular "alter" statement? > > -- > Mgr.

Re: [Firebird-devel] Dropping database default SQL SECURITY
It's the default for a database. It cannot be NULL. Initial NULL means INVOKER. пн, 14 февр. 2022 г. в 16:43, Jiří Činčura : > > Hi *, > > How can I drop SQL SECURITY on database, aka setting the RDB$SQL_SECURITY > column back to "null"? > > -- > Mgr.
