TypeError in self-compiled svn bindings for CentOS 5

[ta_nik@…]

After installing trac i try running trac-admin to create a new environment and get the following error message:

Failed to initialize environment. argument number 1: a 'apr_pool_t *' is expected, 'PySwigObject()' is received
Traceback (most recent call last):

Subversion is functioning normally, running on apache 2.2.8

Trac: 0.11b2 Subversion: 1.4.2 System: CentOS 5 (kernel 2.6.18-53.1.6.el5)

Hmm. This isn't a duplicate of #4165 as no mod_python is involved.

I have a buildbot running something similar.

• CentOS 5 (64-bit)
• python 2.4.3 (python-2.4.3-19.el5) in /usr/lib64/python2.4
• svn 1.4.2 (subversion-1.4.2-2.el5) in /usr/lib64/python2.4/site-packages/svn
• Latest source:sandbox/testing branch which was just merged to 0.11b2.

It looks like you've compiled Python 2.5 and the Subversion bindings yourself in /usr/local. My guess is something went wrong in the configure step for swig. Can you check config.log for it and confirm that it points at the correct Python version?

I'm trying to configure trac 0.11rc1 with Python 2.5.1, svn 1.4.4, SWIG 1.3.33 and PostgreSQL as backend. I go all the way to trac-admin /xxx initenv, but then it fails with "TypeError: argument number 1: a 'apr_pool_t *' is expected, 'PySwigObject(��T)' is received" (see paste below) Although my Python 2.5 and SWIG/SVN are Fedora Core 8 stock.

I also got this on the Python interpreter:

>>> from svn import core
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/svn-python/svn/core.py", line 19, in <module>
    from libsvn.core import *
  File "/usr/lib/svn-python/libsvn/core.py", line 5, in <module>
    import _core
ImportError: /usr/lib/libsvn_fs_base-1.so.0: undefined symbol: db_create

​This mail message says it happens so because Subversion was compiled with BerkeleyDB support disabled. I don't actually need it since my SVN is set to fsfs.

Is there a way I can make it work like this or what should I do if not?

Please add me to Cc as I see it disabled for me.

Not a Trac issue, but a problem with the bindings.

First thing to test is that they should be usable properly outside of Trac. See TracSubversion#Troubleshooting for more.
