BLR for SQL_NULL parameter

[Jiri Cincura]

Hi *,

if I'm creating BLR for SQL_NULL parameter ([1] around line 134), I'm
putting there stuff same as for SQL_TEXT. Is this right? I found this
in server sources (utld.cpp), but I'm not 100% sure.

BTW if I was testing some stuff to put there, with some combinations I
was able to kill server without problem. Nothing in log, the process
just ended.

Will be very interesting to have a look at such sample. And fix server.

Would the .NET binary app with tweaked provider suitable for you?

It should be it. You talked about a crash. So far, I cannot say anything without reproduce.

Cool, it starts now.
But server does not want to crash (B2_5_Release).
I get:

Unhandled Exception: FirebirdSql.Data.FirebirdClient.FbException: I/O error
for file "rrr.fdb"
Error while trying to open file ---> I/O error for file "rrr.fdb"

but server keeps running and responding to incoming connections.

Did you created the rrr.fdb database?

Quick fix for this particular case is ready and committed. But I do not close
a ticket - looks like there is no goood control over bad BLR's in remote, and
we may have some more interesting cases.
