PHP 5.4 Update - php5-suhosin error after update
Last modified: 2014-11-26 06:55:07 CET
During update to PHP 5.4 php5-suhosin is removed but the config remains. This leads to an startup warning:
HP Startup: Unable to load dynamic library
'/usr/lib/php5/20100525/suhosin.so' - /usr/lib/php5/20100525/suhosin.so: cannot open shared object file: No such file or directory at
We need to purge /etc/php5/conf.d/suhosin.ini during the update. Maybe we patch the new php5-common to delete this config file.
There is no simple solution for this and the same problem exists e.g. in standard Debian when updating from Squeeze to Wheezy:
During the upgrade to PHP 5.4 php5-suhosin is uninstalled due to the "Breaks: php5-suhosin (<< 0.9.34)" in php5-common. As such php5-suhosin remains installed in "rc" state with it's conffile in place:
root@master:~# dpkg -L php5-suhosin
- Simply removing /etc/php5/conf.d/suhosin.ini while it's still registered by dpkg is problematic
- There's no mechanism is Debian package relationship mechanics which allows to declare that a package is purged instead of simply removed
- AFAIK we don't have preup/postup scripts for components (otherwise we could run "dpkg --purge dpkg -L php5-suhosin" in postup)
Since the error is only visible in the apache.log and not during e.g. an Apache restart and is only logged if the PHP 5.4 packages are installed on UCS 3.2 I suggest we ignore this for 3.2 and run "dpkg --purge dpkg -L php5-suhosin" in the UCS 4.0 postup script (starting with UCS 4.0 everyone would otherwise see this in the logfiles.
That's OK for me if it is only a log message. Move to UCS 4.

> php5-suhosin" in the UCS 4.0 postup script
Copy&paste error, tthat should of course read "dpkg --purge php5-suhosin"
added dpkg --purge php5-suhosin to postup.sh
OK: r54551 ChangeLog
OK: r54548,54762 postup.sh
OK: dpkg -l php5-suhosin
UCS 4.0-0 has been released:
