RE: Crash relating to apr-util with r893 and latest Apache.

Sander:

Brand new repository (I haven't yet gotten to the "maybe I could try
putting actual DATA into here that I want to KEEP" point quite yet,
hehe).

All of the steps I used to reproduce are echoed by make and are in the
e-mail (this is the same testing script I've been trying to get working
for a while without success), and the first few steps are to remove the
repository and re-create them with svnadmin. I have only one instance
of APR on my system, and it is installed by http-2.0. I have a system
version of db (3.2.9), an old one Subversion installed (3.3.11), and db4
(4.0.14, also installed by Subversion).

[root(2)@dreadnought html]# uname -a
Linux dreadnought.saurik.com 2.4.12-0.3 #1 Mon Oct 22 11:57:46 EDT 2001
i686 unknown

I have a heavily upgraded Red Hat 7.1 installation.

I admit I don't know how to figure out what libraries a binary is linked
to :). However, I _can_ do this:

[root(2)@dreadnought bin]# strings httpd | grep libdb
libdb-4.0.so
[root(2)@dreadnought bin]# cd ../lib
[root(2)@dreadnought lib]# strings libapr* | grep libdb
[root(2)@dreadnought lib]# cd ../modules
[root(2)@dreadnought modules]# strings libmod_dav_svn.so | grep libdb
[root(2)@dreadnought modules]# strings /usr/local/bin/svnadmin | grep
libdb
libdb-4.0.so
[root(2)@dreadnought modules]#

OK, apparently I built http with mod_dav as not a module, if that's
important (I didn't even realize).

This could be a weird compiler issue, but I believe this happened before
I upgraded gcc (which became an issue when one of Apache's or
Subversions requirements yelled at me in it's configure script saying my
version of gcc had dangerous bugs in it and disabled most
optimizations). However, I made sure to recompile everything involved
(db, apache, and subversion) with the new version just in case there was
some weird incompatibility in the binary formats.

Sincerely,

Hi,

Got a bit more information for us?

Can you confirm that mod_dav_svn and apache2 are linked to
db4? Same goes for svnadmin. Did you create the repos
with the db4 svnadmin? Or are you using your old repos(db3)
with the new mod_dav_svn(db4)?

If you could also state your platform and the steps you
took to setup the server that would be great.

Thanks,

Sander
