[firebird-support] Digital signing of Firebird executables, installers etc.
Hello Firebird support, Are there any plans on the horizon to digitally sign Firebird executables, installers etc.? If not can I raise this as an issue?

[firebird-support] Re: How to troubleshoot "connection rejected by remote interface" error? Something has got wrong...
It is superserver.
I tried to skim the source code - tha call stack is:
INET_analyze
INET_connect
send_full(port, packet)
xdr_protocol(>port_send, packet) / bool_t xdr_protocol(XDR*
xdrs, PACKET* p)
case op_connect:
{
connect = >p_cnct; //is this really some function call?
Function with name/address p_cnct?
So - the call packet->p_cnct determines all. I hoped to narrow down the call
stack to the single socket operation from which I could deduce the result of
packet->p_operation (the full list of possible values are in the protocol.h
P_OP enumeration) but at present I can not do it.
My understanding is that p_cnct is expanded further and the resulting
determination of the value of p_operation involves both technical (e.g.
connectivity issues) and logical (e.g. some kind of processing of connection
data done by Firebird server) factors, so I can not rely that those factors
would be logged in some journals of the operating system.
I see that xdr_protocol involved DEBUG_XDR_PACKET(xdrs, p); i.e. I could catch
the error using the debug relesae of the server/client... But I am not user
whether I can put debug release in the production environment...

If you learn Firebird API, you'll see that BLOB's content is requested to client separately.

My client occassionally receives "connection rejected by remote
interface" error while trying to connect to the remote server. I know
that incompatibility of versions between gds32.dll/fbclient32.dll and
server version can create such errors, but those are deterministic
errors that happens always. In my case the error appears and disappers.
I checked:
- CPU, RAM consumption by the Fireird service is normal
- there are no errors in firebird.log
- there are no antiviruses or firewalls
- telnet server 3050 is OK and ping is also OK
- the error happens during connection time only, once the user is
connected to the server, the connection remains and there are no problems.
This is Firebird 2.1 on Linux machine, but such errors can happen with
later version as well, web has many request for help.
There is the following code in the Firebird sources:
{335544421, "connection rejected by remote interface"}, /* 101,
connect_reject */
const ISC_STATUS isc_connect_reject = 335544421L;
#define isc_connect_reject 335544421L
inet.cpp / xnet.cpp / wnet.cpp
rem_port* INET_analyze(Firebird::PathName& file_name,... {
...
PACKET* packet = >rdb_packet;
...
rem_port* port = inet_try_connect(packet, rdb, file_name,
node_name, status_vector, dpb,
dpb_length);
...
if (packet->p_operation != op_accept)
{
*status_vector++ = isc_arg_gds;
*status_vector++ = isc_connect_reject;
*status_vector++ = 0;
disconnect(port);
return NULL;
}
...
}
OK, the conclusions are that "connection rejected by remote interface"
happens when there is no op_accept, i.e. Firebird does not try to
analyse or log/journal the real status of p_operation and the cause
why the p_operation is not op_accept. Essentially, this is code block
that should have never been reached and that is why it is not elaborated.
However - such errors happen and what to do in those case? Are there
some Linux logs that journals off the cases when p_operation is not
op_accept. And essentially - as I can understand, then the cited code
occurrs on the client machine, so, there can be network errors as
well, but why Firebird code puts all the blame on the rejection of the
server?
So confused...
From "gds32.dll" in your post I understand the client is on windows, right?
Windows often reports "connection rejected by remote interface" while in
fact the local firewall (on the clients machine) is getting in the way.
Just my 2 cents

[firebird-support] out-of-memory failure with BLOB
Hello, I have a issue with blob in a stored procedure with BLOB variable. Blob variable is returned by a suspend in a "while do", but the memory allocated to the blob is not released, so memory takes by fbserver increase until a out of memory failure (up to 2Go, the max size of a 32bit process) My test was made with fbserverser 3.04 32Bit To reproduce the issue, just execute the script below After suspend, allocated memory should be release no ? Thank you Eric SET TERM ^ ; CREATE OR ALTER PROCEDURE BLOB_MEMORY RETURNS ( B BLOB SUB_TYPE 1 SEGMENT SIZE 80) AS begin b = 'Test'; suspend; end^ CREATE OR ALTER PROCEDURE BLOB_MEMORY_TEST RETURNS ( B BLOB SUB_TYPE 1 SEGMENT SIZE 80) AS declare variable i integer; begin i = 0; while (i < 15E6) do begin select b from BLOB_MEMORY into b; i = i+ 1; suspend; end end^ SET TERM ; ^ SELECT * FROM BLOB_MEMORY_TEST;
Re: [firebird-support] "12. Don't forget to enable file cache with big Firebird cache page"
Hi Karol, This advice is based on our experience - disabling file cache for big databases (definitely larger than RAM size) leads to slowness. I don't have explanation for this on the theoretical level. If you have real-world example when Firebird works faster without file cache, please provide details about it.
