I'll check this one out. Could be just an order by issue.

[strk]

(In [14867]) Order return from SRF, improving predictability

Should close #3513

[strk]

(In [14868]) Make ordering consistent with the rest of the test

(see #3513)

[robe]

Okay I reneabled testing of 9.6 on debbie. I'm testing locally now.

[robe]

still failing - he is the diff I get locally after svn update

(In [14878]) Make AsGML execution order predictable (see #3513 again)

[strk]

For some reason Node 17 (N17) is expected to be found already visited while it isn't. Funny is that N17 is actually expected to be visited during scan of P1, but P2 is printed first. So I guess before pgsql 9.6 the execution order was: scan P1 first, P2 second; output P2 first, P1 second. This is what I tried to do with changeset r14878 but evidently wasn't working.

[robe]

okay since it's still not working. I took 9.6 out of the matrix testing, that way trunk won't show as a failure, but moved it to a post build check - so it is still tested.

[strk]

Regina could you please drop an url showing the failure, in case it's different from before ?

[strk]

In 14889:

Simplify GML test for P1/P2 to use a single ORDER BY

This is yet another attempt to fix #3513

[strk]

Also please test with r14889

[strk]

I built 9.6 myself and can confirm the fix. Regina please re-enable 9.6 buildbot

[robe]

Okay I readded it 9.6 and made it first to run and fail the whole job if it fails. Manually running it now. I'll reopen if it still fails.
