Re: [HACKERS] [Pgbuildfarm-members] CREATE FUNCTION hang on test machine polecat on HEAD

2011-06-24 Thread Robert Creager

Got another one (no env since the last changes).  I'll try and run the kept 
install from when I killed 22853 (had to use -9) to see if it reproduces the 
problem with the same binaries.  Is there interest in me removing the perl in 
/opt/local/bin/perl?  I can install ccache elsewhere and rename that directory.

 At this point I'm thinking that the perl you've got in /opt/local must
 be bollixing the works somehow, though it's not clear how.  It's also
 really strange that it evidently only fails some of the time ...
 

I've renamed /opt/local so it's not picked up, and change HEAD to build every 6 
hours.  Won't prove it doesn't happen though...  If it appears to work for a 
bit, I can move /opt/local back and see what happens.

I'll see about setting up my iMac at home for the build farm for another Apple 
machine.

Anything you'd like to change, or run, or something else?

 You could find out by digging around at
 http://www.opensource.apple.com/
 polecat appears to be running OSX 10.6.7, so this is what you want:
 http://www.opensource.apple.com/tarballs/perl/perl-63.tar.gz
 
 Thanks!
 
 Another question worth asking here is whether PG is picking up perl
 5.10.0 or 5.8.9, both of which are shipped in this OSX release.
 
 I was looking at
 http://buildfarm.postgresql.org/cgi-bin/show_stage_log.pl?nm=polecatdt=2011-06-07%2015%3A23%3A34stg=config
 which seems to point at 5.10.0.
 
 Robert: perl -V might be useful

Hmm...  This might be a problem:

which perl
/opt/local/bin/perl

type -a perl

 If there's anything perl-related in /usr/local/lib (not /opt/local/lib),
 that could be confusing matters.

That's what I get for doing this in a meeting, doing both poorly.

No perl in /usr/local/lib.

Hrm they don't seem to touch util.c where PL_get_hash_seed lives at
all :-(. I also looked at 5.8.9 and Perl_get_hash_seed looks the same
as in 5.10.0.

Perl_get_hash_seed is basically:

unsigned long myseed = 0;
if(s) {
  
  myseed = atoul(s);

srand(Perl_seed());

gettimeofday(when, NULL);
u = when[0] + SEED_C2 * when[1];
u += getpid();
u += PTR2UV(PL_stack_sp);

I don't suppose /dev/urandom blocks on OS X?  Granted, I may have
missed something in translation with the macro fest that is perl...

Shouldn't the backtrace show a syscall in that case?

I guess one would need a debug perl build + single stepping for a more 
convincing answer...

 I don't suppose /dev/urandom blocks on OS X?

The man page for it avers not, and besides it's hard to believe that
there wouldn't be a libc routine or two on the stack if we were blocked
in a kernel call, and also Robert showed that the process was consuming
CPU time, so it's not blocked.  Tis puzzling if there's no loop in the
function.

 I wondered if we were possibly exhausting some entropy pool. It seems like
 this would be just such a bad bug that it would be amazing if we were the
 first to trip up on it. But I guess you never know.

/dev/urandom is the one that's supposed to be unblocking (that's
what the u is for).

Supposedly, /dev/random and /dev/urandom behave identically on OS-X,
using Yarrow for RNG.  It shouldn't be blocking.

Yeah.

Well there is one, I snipped it out for brevity (I don't see how it
could be at fault):

const char *s = PerlEnv_getenv(PERL_HASH_SEED);
if (s)
   while (isSPACE(*s))
 s++;
if (s  isDIGIT(*s))
myseed = (UV)Atoul(s);
else
{
  srand(Perl_seed());
  myseed = rand() *UV_MAX;
   
}

Im looking at the raw perl 5.10.0 source... I wonder if apple is
shipping a modified version?

You could find out by digging around at
http://www.opensource.apple.com/
polecat appears to be running OSX 10.6.7, so this is what you want:
http://www.opensource.apple.com/tarballs/perl/perl-63.tar.gz

Another question worth asking here is whether PG is picking up perl
5.10.0 or 5.8.9, both of which are shipped in this OSX release.

I was looking at
http://buildfarm.postgresql.org/cgi-bin/show_stage_log.pl?nm=polecatdt=2011-06-07%2015%3A23%3A34stg=config
which seems to point at 5.10.0.

Robert: perl -V might be useful

 Hmm...  This might be a problem:

 which perl
 /opt/local/bin/perl

 type -a perl
 /opt/local/bin/perl
 /usr/bin/perl

 /opt/local/bin/perl -V
 This is perl, v5.8.9 built for darwin-2level

The configure log mentioned upthread says it's finding /usr/bin/perl,
so apparently the buildfarm is running with a different PATH than you're
using here.  But that log also shows

configure:7158: checking for flags to link embedded Perl
configure:7174: result:  -L/usr/local/lib  
-L/System/Library/Perl/5.10.0/darwin-thread-multi-2level/CORE -lperl -ldl -lm 
-lutil -lc

If there's anything perl-related in /usr/local/lib (not /opt/local/lib),
that could be confusing matters.

 That's what I get for doing this in a meeting, doing both poorly.
 run_build.pl:
 #!/usr/bin/perl

 No perl in /usr/local/lib.

Hrmph.  FWIW, I see the same configure results on my own Macbook Pro:

configure:7158: checking for flags to link embedded Perl
configure:7174: result:  -L/usr/local/lib  
-L/System/Library/Perl/5.10.0/darwin-thread-multi-2level/CORE -lperl -ldl -lm 
-lutil -lc

But I tried make installcheck in plperl quite a few times with no
problems.  (And yes, I tried some assorted settings of PERL_HASH_SEED,
as well as none at all.)

At this point I'm thinking that the perl you've got in /opt/local must
be bollixing the works somehow, though it's not clear how.  It's also
really strange that it evidently only fails some of the time ...
