I am trying to debug my socket-level interface to the backend, which implements the 6.4 protocol. It works for general queries, but I have a problem with large objects. lo_create and lo_unlink seem to work OK; I get an oid which looks ok and there is a corresponding xinv??? file in the base/ directory. lo_open returns 0 as a file descriptor. However, following up with one of the other lo functions which take descriptor arguments (such as lo_write or lo_tell) fails with ERROR: lo_tell: invalid large object descriptor (0) Looking at be-fsstubs.c it seems that this arises when cookies[fd] is NULL. I don't know what this might come from: the lo_tell is sent right after the lo_open, on the same connection. Running the sample lo program in C works, so I suppose the problem must come from the bytes I'm sending. Any ideas what could cause this?
