failed to map segment from shared object: Permission denied

Hello –

 

*** My (immediate) problem ***

 

In browsing into the topmost directory of my repository via ViewVC (version 1.0.4) I encounter this traceback:

 

Traceback (most recent call last):

  File "/var/www/viewvc/lib/viewvc.py", line 3665, in main

    request.run_viewvc()

  File "/var/www/viewvc/lib/viewvc.py", line 253, in run_viewvc

    import vclib.svn

  File "/var/www/viewvc/lib/vclib/svn/__init__.py", line 25, in ?

    from svn import fs, repos, core, delta

  File "/usr/local/subversion_1.4.3/lib/svn-python/svn/fs.py", line 19, in ?

    from libsvn.fs import *

  File "/usr/local/subversion_1.4.3/lib/svn-python/libsvn/fs.py", line 5, in ?

    import _fs

ImportError: /usr/local/subversion_1.4.3/lib/svn-python/libsvn/_fs.so: failed to map segment from shared object: Permission denied

 

A colleague of mine believes this is telling us that, when loaded into memory, one of the segments of the shared object is inaccessible.

 

 

*** What I’ve already investigated **

 

o Ownership of the viewvc installation, as well as the the Subversion repository, have all been set to apache:apache, under which httpd is running.  I am also running svnserve as apache.  Likewise, all file permissions have been set to 777.

 

o I have also changed the ownership of the offending shared object to apache:apache.

 

o I think the true problem may actually be responsible for some warnings in the build output of the ‘make swig-py.’  Here’s a representative example:

 

./subversion/bindings/swig/svn_delta.i:98: Warning(453): Can't apply (svn_delta_editor_t const *EDITOR,void *BATON). No typemaps are defined.

 

There is no file named typemaps.i anywhere in the source directory, although there are frequent attempts to import it.  Should there this file already exist?

 

 

I appreciate any assistance any of you may be able to offer.  I’m running a newly-compiled Subversion 1.4.3; the Python version is 2.3.4, the version already included in RH 4 EL EMT64.

 

Thank you!

 

 

Mike Lund
