Hey, you also shouldn't have email! I wasn't expecting an answer before
Monday (and still don't, just replying to document what I find).
It is indeed in the engine, but unconditionally turned off:
bool TSyncHeader::execute(void)
...
// -> we should resend the previous answer again.
if (
fSessionP->getSyncAppBase()->canBufferRetryAnswer()
) {
// we can resend answers
PDEBUGPRINTFX(DBG_ERROR,("last answer buffered -> sending it
again"));
fSessionP->fMessageRetried=true;
return false;
}
else {
// use not foolproof poor man's method
// %%% This will fail if the previous message received has
// changed datastore/session/package states, but will work
if
// the retry is within a phase (probable case for long
sessions)
PDEBUGPRINTFX(DBG_ERROR,("No buffered answer to resend -> just
process msg again (WARNING: possibly messes up session state)"));
}
The only implementation of canBufferRetryAnswer() that I find returns
"false", so we end up in the else branch and indeed, in some cases the
state gets messed up.
I'll keep looking into how I can enable this. Hints welcome.
