I was hoping that someone with something faster than a SPARC 2 would do the biz and get the same results. So we have at least two problems, some code that is tickling a gcc optimiser bug (gcc 2.7.2.1 in my case) and an alignment bug in our code that affects SPARC architecture. I've half a mind to see if there is a later version of gcc that does the optimisation correctly. (rpm format for Redhat 4.2) The "create function" problem is a little harder for me to see a way forward. ( my debugging skills are very few.) Keith.

Hmm. Bruce's most recent patches didn't fix my problems on Linux/i686
reported earlier. So I figured I'd try a full build with -O0 just to see
if it helped. Not only did it not help, but I got several other
regression tests failing, some with core dumps which did not crash with
-O2. Weird.

Can you try:
select * from pg_index;
Crashes here. Not good.

One idea is to track heapDescriptor from CatalogIndexInsert() all the way down into the lower functions. Compile with assert checking, which I assume you are already doing.

I don't know if this helps, but here's what I've done so far. I'm now on
a Solaris Box, since the optimization thing seems to be similar to the
Linux Box. Its just easier for me to work on the Solaris Box.
When indexing.c is compiled with -O2, I get a core dump. (Big news.)
The core dump occurs at line 208 of backend/access/common/heaptuple.c.
at this memmove.
{
data = (char *) LONGALIGN(data);
memmove(data, DatumGetPointer(value[i]),
att[i]->attlen);
data += att[i]->attlen;
}
This consistantly happens when tupleDesc->natts is 1. When i = 1 on the
second time on the outer loop, value[1] is something like 2123236.
This is out of range when it gets derefenced, memmove barfs.
I was backtracking and turning on debugging one file at a time, but got
lost in fmgr.c.
I'll insert the asserts like you suggested.
Bruce, I can let you on this machine if you like.
Thanks,
Tom

Can we try a simple -O rather than just -O2 and -O0. Could this be some type of optimizer bug in gcc2/Solaris? Everything is pointing to indexing.c, from both the initdb failure and the create function failure. But I can't see anything wrong in there, and other platforms seem to be OK. Someone mentioned that Solaris does not use -O2 by default, and there may be a good reason for this. The new code is more streamlined from the megapatch, and perhaps the optimizer is now able to do too much optimizing. I don't want to go casting blame other places, but I think gcc that may be the cause, and if it is, we just need to lower the default optimization for those platforms. Let's try adding Assert checking with the configure --enable-cassert option, and compiling with -O rather than -O2 and see what happens. -- Bruce Momjian | 830 Blythe Avenue maillist@candle.pha.pa.us | Drexel Hill, Pennsylvania 19026 + If your life is a hard drive, | (610) 353-9879(w) + Christ can be your backup. | (610) 853-3000(h)

Bruce,
I do not know if this problem is related in any way, but I have a serious
problem on AIX 4.1. I am jumping in here because there is a chance they are
related. Just manifest differently.
If I add an index to a table I can no longer use the table. In essence,
the look up on relname in pg_class fails. If I:
SELECT * FROM pg_class WHERE relname = 'table_i_just_indexed'
-- or \d table_i_just_indexed
I get no results.
SELECT * FROM pg_class
Displays it perfectly. So does:
SELECT * FROM pg_class WHERE relname like '%table_i_just_indexed'
If I manually correct relname:
UPDATE pg_class SET relname = 'table_i_just_indexed' WHERE relname like
'%table_i_just_indexed'
Everything seems to function normally again.
I can not reproduce on my Linux box. Assertions show nothing. This can't be
good.
Andreas, are you having any success?

Uh, no, Linux/i686 is showing trouble too, but not in the initdb stage.
The Sparc platforms will be more sensitive to byte alignment problems,
especially within C structures, so this may be illustrating a
cross-platform problem more clearly.
There is a repeatable indexing and (perhaps) caching problem I see in
the regression tests. Annoyingly, the problems get slightly worse at the
moment when compiling with -O0.
There is a fundamental problem lurking somewhere, and there may not be
much point in going beta unless you think that more testers will help to
track down the problem.

Well, yes, just not as strange as my tests :) You don't have int8
enabled, and if your compiler and libc allow it I'd like to get that
going. But that isn't a problem.
You have a core dump from the "having" test. Is that a known problem
with someone working on a solution? The test worked on my ~month-old
development tree (I could probably figure out the vintage of that tree
to more precision if it would be helpful), so something has happened in
the meantime.
I suspect that (possibly) more than one thing is going on, since there
were some changes directly related to removing the oddball OID types as
well as perhaps cleanup changes made while traversing the code.
Something may have crept in there.
If these tests are the only ones showing problems on your machine, then
consider yourself lucky. I've got several more failures, including the
one where I can't create indices on a table until after terminating and
restarting the session. The Sparc contingent sees more problems than I,
but they are on a Risc machine so will see alignment problems if they
are present.

OK, this test did not fail on my development tree from a month ago. What
changed? I'm seeing it fail here also.

Yes, very strange.

I believe David Hartwig has claimed this problem, and knows the cause.
He posted something recently.

That sounds like *so* much fun ;-)
OK, I've been ignoring the problem until now, and of course may not be
of any help even if I were trying to help. I'm also not quite up on the
history and sequence of events which led to our current state, and I'm
not sure we have a strong regression history yet to pin this down.
At the moment we have Bruce and the two sparc guys working on it, and
Bruce can't reproduce the problems on his machine and Keith's machine is
so dog-slow that he can't do much testing which involve full rebuilds.
Boy, it hasn't been long since that model Sparc was the best thing
going, eh?
Does anyone else have a machine (Linux x86, for example) which exhibits
problems with the current development tree, and who has an interest in
helping to track this down?
I hate to step away from docs, but could for a while if that would be
helpful. I've got a fairly fast machine and can try pinning down when
the problems started by doing full builds on fresh trees. Or since we've
been making steady incremental improvements to the tree, maybe we should
focus on a particular problem; my "can't create another index in the
current session" problem is probably related to whatever else is going
on with indices.
In general the problems persist across different "-O" compiler settings
and across different architectures and compilers, though with different
symptoms, so I would think that this is not a compiler bug per se.

I was on Thomas A. Szybist machine for two hours, and even though I was telnet'ed across three Internet machines to get there, it made my PP200 look like it was sitting still. Amazing speed.

I just grabbed grabbed gcc 2.8.1 from smc.vnet.com. I should have that
installed later today. Full rebuilds are not a problem for me. I did
just get a project bubbled to the top of my queue here that should take
about a day or two. I certainly can try patches and such, but I may
not have time plod through with gdb for a few days. (Not that I can
help much anyway.) I'm also going to be away for Labor day starting
Friday night EST. I'm returning on Tuesday night EST.

The first patch addressed problems caused by a machine dependency on the degree of accuracy of datetime. CVS is currently showing this first patch. The second patch was to fix my first patch. It has NOT been applied yet. The problem with he first patch, which you are seeing now, is that the test case demonstrates another bug which has nothing to do with having. It has to do with GROUPing by a function and the argument of the function not appearing elsewhere in the target list. Weird! In any case the latest patch will fix the regression. BTW, I have also sent one other patch that I am waiting to see in CVS. These one is an interim AND/OR memory exhaustion fix.

Yes, I am behind on the patch applications. Marc probably stopped while I did my mega-cleanup, and I have been scratching my head on the platform failures. Hopefully one of us will get it soon. -- Bruce Momjian | 830 Blythe Avenue maillist@candle.pha.pa.us | Drexel Hill, Pennsylvania 19026 + If your life is a hard drive, | (610) 353-9879(w) + Christ can be your backup. | (610) 853-3000(h)

No rush, I can see you're synapses are all firing on this index bug. Just a reminder so it doesn't fall through the cracks. More important, am relieved (in advance) that you have found the problem in the index code. Can I assume there will be a snapshot I can get tomorrow from my business location to try out on my AIX box? I am anxious to know this is behind us. Appreciation :)

Thanks to all the bug reports and tracebacks. They clearly pointed to the problem.
