Обсуждение: dblink regression failure in HEAD
I found regression test for dblink in HEAD was failed on my machine. One buildfarm machine also reported the same failure. http://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=pangolin&dt=2010-07-12%2013:37:06 It seems to come from the recent fix for dropped column support, but I'm not sure why other machines can pass the test. ================= pgsql.29332/contrib/dblink/regression.diffs =================== *** /home/slux/buildfarm/HEAD/pgsql.29332/contrib/dblink/expected/dblink.out Mon Jul 12 13:37:07 2010 --- /home/slux/buildfarm/HEAD/pgsql.29332/contrib/dblink/results/dblink.out Mon Jul 12 13:51:40 2010 *************** *** 905,926 **** ADD COLUMN col4 INT NOT NULL DEFAULT 42; SELECT dblink_build_sql_insert('test_dropped', '2', 1, ARRAY['1'::TEXT], ARRAY['2'::TEXT]); ! dblink_build_sql_insert ! --------------------------------------------------------------------------- !

What this looks like to me is that dblink.c doesn't contain the fix
that the new regression test is checking for.
pangolin is pulling from the git mirror, which I still don't trust
further than I can throw it. How about you?

As for the git mirror, I can only speak for the mirror I maintain, which is validated on every live branch every day against CVS, so far without a hiccup, and has four of my buildfarm members happily building against it (and possibly others). cheers andrew

A few experiments later: I can reproduce the failure shown on pangolin
exactly if I revert the latest changes in sql/dblink.sql and
expected/dblink.out, while keeping dblink.c up to date. So I guessed
wrong on which file was out of sync, but I say confidently that this
is a repository sync problem.

I'll check with Scott on this, sorry, but it might be an issue with the
machine and not the repository. That's the box that he's been doing the
performance-farm work on and it's entirely possible soemthing got
screwed up there. Of course, it could also be a repository problem,
I'll find out.
Thanks,
Stephen
