Bug 543348 – net-analyzer/fail2ban-0.9.1 - ERROR Unable to import fail2ban database module as sqlite is not available

• Status: RESOLVED FIXED
• Product: Gentoo Linux

emerge--info

Launching fail2ban gives the message
ERROR   Unable to import fail2ban database module as sqlite is not available.
in /var/log/fail2ban.log

Got dev-lang/python-2.7.9-r1 installed with +sqlite to get www-client/firefox-31.4.0 installed, but fail2ban is launched with /usr/bin/python3.3, which hasn't this flag set.

=> fail2ban should force +sqlite to python to get installed.

Cheers.

In /etc/portage/packages.use[/monolithic]
using
>=dev-lang/python-2.7.9-r1 sqlite
instead of =dev-lang/python-2.7.9-r1 sqlite
that was placed to get Firefox compiled, and recompiling makes fail2ban working with a
"INFO    Connected to fail2ban persistent database '/var/lib/fail2ban/fail2ban.sqlite3'" in /var/log/fail2ban.conf

Your emerge output should have included a warning about dev-lang/python not having been compiled with USE=sqlite.

If you say so, yes. But then, during the install process, among all the logs.
Not at the very end, I would have seen that.

Maybe it ought to say "WARNING" where it says "ERROR".

This should be fixed in 0.9.2. Please test.

I just installed fail2ban-0.9.2 and didn't get any of the warnings about dev-python/pyinotify, app-admin/gamin or dev-lang/python[sqlite] from the pkg_postinst() function. This is caused by the enclosing

  if ! has_version ${CATEGORY}/${PN}; then ... fi

As this is called POST installation the version ${PN} IS installed and so the condition is never true.

Would you please consider reopening this bug? The problem is still present in 0.9.6. Because it is an error and not a warning, fail2ban does not stop or restart cleanly. There should be at least some dependency on sqlite or USE +sqlite, or a "downgrade" of the error to a simple warning.
