If the IDL isn't configured to monitor any of the columns in a table at all, and table->need_table is false, then I don't want to log anything at all, because the IDL doesn't care about that table at all; that's why it's written the way I did it. > > @@ -2385,11 +2544,11 @@ static void > > ovsdb_idl_update_has_lock(struct ovsdb_idl *idl, bool new_has_lock) > > { > > if (new_has_lock && !idl->has_lock) { > > - if (!idl->monitor_request_id) { > > + if (idl->state == IDL_S_MONITORING) { > > idl->change_seqno++; > > } else { > > - /* We're waiting for a monitor reply, so don't signal that the > > - * database changed.

And this > could be problematic? A transition to IDL_S_MONITORING will increment change_seqno (right?), so there's no need to increment it here unless we're already in that state. A bit stronger: we should not increment here unless we're in that state, because clients assume that when change_seqno is nonzero that the database has been populated. > > diff --git a/tests/ovsdb-idl.at b/tests/ovsdb-idl.at > > index 89752f0..57642be 100644 > > --- a/tests/ovsdb-idl.at > > +++ b/tests/ovsdb-idl.at > > @@ -496,3 +496,78 @@ OVSDB_CHECK_IDL_PY([getattr idl, insert ops], > > 002: i=2 k=2 ka=[] l2= uuid=<0> > > 003: done > > ]]) > > + > > +AT_SETUP([idl handling of missing tables and columns - C]) > > +AT_KEYWORDS([ovsdb server idl positive]) > > +OVS_RUNDIR=`pwd`; export OVS_RUNDIR > > + > > +# idltest2.ovsschema is the same as idltest.ovsschema, except that > > +# table link2 and column l2 have been deleted.
