PostgreSQL 8.0.0 Release Candidate 3

Does this release incorporate a change to the bgwriter or was it
determined to leave it as-is until 8.1?

Regards,
Jeff Davis

Hello Marc,

As was anticipated, time between Release Candidate 2 and 3 was nice and
short, with more changes being made now to Documentation vs Code.

A current list of *known* supported platforms can be found at:

http://developer.postgresql.org/supported-platforms.html

We're always looking to improve that list, so we encourage anyone that
is running a platform not listed to please report on any success or
failures with Release Candidate 3.

Baring *any* coding changes (documentation != code) over the next week
or so, we *hope* that this will the final Release Candidate before Full
Release, with that being aimed for the 15th (or earlier).

As always, this release is available on all mirrors, as listed at:

http://www.postgresql.org/mirrors-ftp.html

1. this URL doesn't exist any more. I only found the following:

http://wwwmaster.postgresql.org/download/mirrors-ftp

2. I visited some of the mirrors as well as ftp.postgresql.org and there
the source tarballs of rc3 have file date 31.12.2004 22:39 while Tom
Lane posted last corrections related to copyright messages on 01.01.2005
23:14, and Bruce Momjian posted Updates related to UTF-8 on 01.01.2005 17:36

So my question: are there really the correct rc3 tarballs around?

With best regards,

Roland

Are you sure this list is complete? I don't see the ps2, xbox, or
gamecube listed under supported platforms :-)

There are no bgwriter changes in RC3. We don't know yet if they will be
in 8.0 final.

Well, a build with regression test failures is not "good", in particular when
it is a regression from previously behavior.

what failure. both my MIPS and MIPSEL system are reporting OK on the builds. The ARM failed only the "point" test.
It looks like a rounding error (ARM doesn't have a build in fp unit)

RC3 on Microsoft VirtualPC with Debian Testing passes all tests.

Running a fresh install of Debian/Testing on Microsoft VirtualPC works
fine. I'm not sure if this counts as a separate platform or not, since
all it really says is that VirtualPC emulates a PC well enough. It's a
pretty nice way of running Linux servers on sales guy's windows laptop.

I notice that Ubuntu is not yet on this list. I can confirm that
PostgreSQL 7.4.5 is supported under Ubuntu 4.10 (warty) on all platforms
(x86, amd64 and ppc) and that PostgreSQL 7.4.6 is supported under Ubuntu
5.4 (hoary) on all platforms. Version freeze for hoary is today, so that
version is fixed and the 8 series won't be officially supported until
the following release (October 2005), although installing the Debian
packages should work just fine.

Welcome to the New Year all, and the final days of testing for 8.0.0.

This will hopefully be our final Release Candidate, with a Full
Release happening late next week. There are several Windows related
fixes in this Release Candidate, with a full list of changes viewable
in the Changelog available on the FTP server.

running a platform not listed to please report on any success or failures
with Release Candidate 4.

Baring *any* coding changes (documentation != code) over the next week or so,
we *hope* that this will the final Release Candidate before Full Release,
with that being aimed for the 15th (or earlier).

As always, this release is available on all mirrors, as listed at:

Hi,

I've tested RC4 on Linux on the PlayStation 2 again
(compare
http://archives.postgresql.org/pgsql-hackers/2004-08/msg01339.php).

With --disable-spinlocks everything but the two floating point tests
succeeds (regression output and diffs attached).

The Playstation 2 hardware manuals confirm that the FPU has
no support for NaN and +/-Inf. That explains the regression diffs.
(EE Core User's Manual Version 5, p. 153)

In summary one might conclude that PostgreSQL 8 works on Linux on the
Playstation 2 as far as the hardware supports it.

Kind regards,
Chris.

Well, it does not readily explain that 'infinity' is rejected as invalid
input syntax. You should get an overflow or some large value, at
least.

The relevant code is in src/backend/utils/adt/float.c.

You seem to be under a misconception about the purpose of that list.
It has nothing to do with what Postgres releases are packaged by
various distributions. Entries on the list mean that someone has
verified that the *source code* distribution builds per instructions
and passes regression tests on that platform.

If you are trying to say that you personally have verified that for
Ubuntu, you didn't phrase it clearly.

You're right.
I had a look at the code.
It seems strtod() is to blame.

This sample program

#include <stdio.h>
#include <stdlib.h>
#include <errno.h>
int main()
{
char *endptr;
double val;
char *num = "Infinity";
errno = 0;
val = strtod(num, &endptr);
printf("input string is '%s'\n", num);
printf("strtod returned val = %lf\n", val);
printf("errno = %d\n", errno);
printf("endptr points to '%s'\n", endptr);
}

on the PlayStation 2 returns:

input string is 'Infinity'
strtod returned val = inf
errno = 0
endptr points to 'inity'

float.c's conversion routine cannot deal with a strtod that just eats
the 'Inf' part of 'Infinity', so the remaining 'inity' is causing the
syntax error (from line 522 in "float.c").

Consistently, this works with the so compiled version of PG:

postgres=# select 'Inf'::float8;
float8
----------
Infinity
(1 row)

Would it be worth treating this case apart in float.c, or should we just
blame the PlayStation's 2 Linux (quite old version 2.2.2) Gnu C library
to be broken?

I wonder how many implementations of strtod behave this way?
On a few other boxes of mine I've seen versions that accept 'Infinity'
as a whole or reject it as a whole

Bye, Chris.
