Error with Firebird 4.0

[krixano]

I'm trying to use this with firebird 4.0 and am getting an error. It seems the error is happening when I'm trying to do con.Ping() right after doing an sql.Open().

panic: runtime error: slice bounds out of range [:2] with capacity 0

This does not occur in my environment, but an error occurred here. https://github.com/nakagami/firebirdsql/blob/v0.9.4/wireprotocol.go#L508

Is it failing around authentication negotiation?

[nakagami]

Can you tell me the name and value of the uncommented line in firebird.conf?

[krixano]

There are a few uncommented lines in firebird.conf, so here they are:

RemoteAccess = true
ConnectionIdleTimeout = 60
WireCrypt = Disabled
ServerMode = Super

I also tried with "WireCrypt = Enabled" as well. The server is running on a computer that is directly connected to another server via Ethernet, so encryption wasn't absolutely necessary and in Firebird 3 I found it slowed things down a bit. The connection string has "?wire_crypt=false" at the end of the db path.

[krixano]

Oh, also, I was able to connect to the server "remotely" with FlameRobin and isql, just not with this library.

Probably fixed tagged with v0.9.5

If you are happy with this, please close the issue

[krixano]

It seems to work now. Thanks!

I did have to use the latest commit's hash with go get to update for some reason, but it ended up working.
