Description

« Hide

Transaction ID type (TraNumber) has become 64-bit in Firebird 3.0 and later versions.
isc_concurrent_transaction and isc_rec_in_limbo errors report concurrent transaction ID as isc_arg_number (32-bit signed integer).
This results in transaction numbers truncation in 32-bit builds or when status vector is sent over the wire.

I suggest to change transaction ID type to isc_arg_string when it is stored in status vector.
