[php-maint] Bug#799155: php5-common: sessionclean doesn't touch session files

[Bernat]

Package: php5-common
Version: 5.6.13+dfsg-0+deb8u1
Severity: normal
Tags: patch

Dear Maintainer,

I've observed that sessions have a short living no matter what the
session.gc_maxlifetime setting is.

I've debugged the sessionclean script and found that it never touches
the session files so they will be removed even when they're still in use
for the specified time.

The variable proc_names is set inside the while loop that is in a
pipelined command, thus the variable isn't updated outside the loop.

I've modified the script so everything up to the touch loop runs inside
the same subshell. Patch provided.

Best regards,
Bernat Arlandis
