Problem with AIX 5300-11-01-0944

Hello,

 

I'm running my Subversion server on AIX and last Saturday I decided to update my server to the latest IBM fix pack, 5300-11-01-0944.  I was upgrading from version 5300-09-02-0849 where everything was running fine.

 

Once I installed this fix pack and rebooted, I noticed that 'svnserve' was not running.  I tried to start it manually and got a 'Segmentation Fault'.  I then tried to run just a 'svn' command and got the message to ' Type 'svn help' for usage'.  I tried that and got another Segmentation Fault.

 

I then proceeded to download the 1.6.6 version, rebuilt it and still, Segmentation Fault.  Next, I downloaded the latest apr and apr-util.  Rebuilt those and then Subversion and still got the same error.

 

At this point I decided to rollback my latest fix pack.  After doing that and as I expected, Subversion started, 'svn –help' works and I'm back in business.

 

Can you let me know why I cannot run Subversion with the latest IBM patches?

 

Here's what my config script looks like:

 

-----------------------------------------------------------------------------------------------------------------------

cd /usr/local/subversion-1.6.6

#

export LD_LIBRARY_PATH=/usr/local/bdb45/lib

export LDFLAGS="-lpthread"

#

./configure --with-apr=/usr/local/apr \

            --with-apr-util=/usr/local/apr \

            --without-apxs

#           --with-apxs=/usr/local/apache2/bin/apxs

-----------------------------------------------------------------------------------------------------------------------

 

If you need any more information, just let me know.

 

Thanks,

You and me both.
I hope you have a mksysb image...

Hi Chris,

I did a mksysb plus I just applied the updates, not committing them so it was easy to roll it back.

How did you figure out the libiconv.a was the culprit?

Thanks,

Ronnie

Oh, about three-four days of no sleep! :-)

When I looked at the core dump via dbx, I could see that it dumped at check_sbcs +104, so in the check_sbcs routine. I googled that, and I found that there were 'theoretical' issues in the xlate.c module that has the check_sbcs routine in it. Well, we're not theoretical anymore dorothy... :-)

Looking at the source of check_sbcs, I could see that there were calls to either apr_iconv or native iconv.

With a friend's help, he pointed me at bos.rte.iconv (look at lslpp -f bos.rte.iconv) and you'll see that libiconv.a is in there.

This package was updated in TL8 and TL11.
So I set out to proove it.
Base install 5.3.0.0 Good.
5.3TL8 Good.
5.3TL10 Good.
5.3TL11 Broken.
Copy TL10's libiconv.a to the TL11 machine (actually repoint it via a symlink), and we're good.
Case closed.

After digging a little more, we can see:

http://www14.software.ibm.com/webapp/set2/fixsrch/FixSearch?release=53&pageNumber=1&searchTerms=bos.rte.iconv+5.3.11.0&sortBy=2&submit=Search

which leads to:

Let's hope they add a regression test for this one.
