I looked at that. The basic issue is that Gavin wants special handling
for ON COMMIT, meaning he only wants to activate the ON COMMIT code when
the transaction is committed and it is an end block, or it is not a
commit but it is an abort.
What I don't understand is how he would get into this function unless
either is true. The two call locations would seem to be in transaction
commit/abort routines. I have to say I am confused by the various
TBLOCK values and their progression. I can't find any comments on them
and the code seems contorted.
Tom, can you guess on why they are there? I hear Gavin is traveling in
Europe for the next week or two.
