[php-maint] Bug#388808: php5: disabling session.gc_probability prevents garbage collection if alternate session.save_path is used

[Oscar Merida]

Package: php5
Version: 5.1.6-0.dotdeb.2
Severity: minor

If your php script or application uses a different session.save_path without also setting session.gc_probability to non-zero, old sessions will not be 
deleted, since garbage colleciton won't run.

The comments around session.gc_divisor should be amended to make sys admins aware of this.  Something along the lines of:

; This is disabled in the Debian packages, due to the strict permissions
; on /var/lib/php5.  Instead of setting this here, see the cronjob at
; /etc/cron.d/php5, which uses the session.gc_maxlifetime setting below
; If your php scripts use their own session.save_path, either make sure they
; enable garbage collection by setting session.gc_probability or globally
; enable it here.
