Thread: CVS regression test failure on OBSD
When I run 'make check' on the CVS version (today and for the last serveral days), I have been getting interesting failures. Some of the tests fail, but the interesting part is that not the same tests always fail. Example: bpalmer@mizer:~/APPS/pgsql>diff 1 2 1c1 < boolean ... FAILED --- > boolean ... ok 3c3 < name ... ok --- > name ... FAILED 5c5 < text ... FAILED --- > text ... ok 9,10c9,10 < oid ... FAILED < float4 ... ok --- > oid ... ok > float4 ... FAILED In the regression.diff file, I keep seeing this: *** ./expected/name.out Tue Jan 4 11:19:34 2000 --- ./results/name.out Sat Jan 6 16:36:34 2001 *************** *** 1,124 **** ! -- ! -- NAME ! -- all inputs are silently truncated at NAMEDATALEN (32) characters ! -- ! -- fixed-length by reference ! SELECT name 'name string' = name 'name string' AS "True"; ! True ! ------ ... ... ... ! (2 rows) ! ! DROP TABLE NAME_TBL; --- 1 ---- ! psql: Backend startup failed ====================================================================== Any ideas where to look for this one? When I run the regression test WITH ANOTHER INSTANCE OF PGSQL running, I got an error telling me that I needed more SEMMNI or SEMMNS. I recompiled my kernel with the values of 1024 and 2048 respectivly, and that seems to have solved the problem, but they may still be related. Any ideas? - Brandon b. palmer, bpalmer@crimelabs.net pgp: www.crimelabs.net/bpalmer.pgp5

In the postmaster: the fork() to launch a backend is failing. There
should be a more detailed message in the postmaster's stderr log,
but almost certainly it's a resource-exhaustion issue. Does your
kernel enforce a per-userid limit on the number of processes, for
example?

I have rolled up the process ulimit (soft / hard) to 256 and the Open Files to 256. There are still, however, 4 tests that fail.

Sweet. Thanks, looks like the problem is solved. Should me make note of the changes what were needed for OBSD somewhere? b. palmer, bpalmer@crimelabs.net pgp: www.crimelabs.net/bpalmer.pgp5

Applied, thanks!

If there's anything that users need to know beyond the standard build
instructions, perhaps we should add a doc/FAQ_OBSD ...

It wouldn't surprise me if the error messages changed between releases of the OS -- it's happened to FreeBSD as well. Perhaps they should be qualified by version. -- Peter Eisentraut peter_e@gmx.net http://yi.org/peter-e/

I think you read the message backwards --- we were adding the entries,
not removing them. (The patch was reversed as given, which is a common
mistake.) As patched, the entries for OpenBSD look pretty much like
those for the other flavors of BSD, which gives me a nice warm fuzzy
feeling about it...

A few problems came up with 7.1CVS for i86 OpenBSD. Here is a writeup on what I learned and how I solved the problems. - Brandon b. palmer, bpalmer@crimelabs.net pgp: www.crimelabs.net/bpalmer.pgp5

Can you check http://www.postgresql.org/devel-corner/docs/postgres/kernel-resources.htm#SYSVIPC to see if the description for FreeBSD is also applicable (at least in similar form) to OpenBSD? I'm currently writing up a section about the process and file limit issue, which will end up nearby the section linked to above. -- Peter Eisentraut peter_e@gmx.net http://yi.org/peter-e/

Close enough. > I'm currently writing up a section about the process and file limit issue, > which will end up nearby the section linked to above. I still don't know how to know what the max allowed (by the system) are. Anyone? - b b. palmer, bpalmer@crimelabs.net pgp: www.crimelabs.net/bpalmer.pgp5
