Bug description: session.gc_maxlifetime does not work (Reopen Bug ID #3793)
Befor going into the bug-report an importent question:
session.gc_maxlifetime documented as a lifetime messured in *seconds* with
default = 1440
1440s = 24min. hmm.... 24min ??
Expectiong the gc_maxlifetime to be rather long 24 min. seams a short time
AND 24 relates more to 24h! So is it realy *seconds* ?!

The Bug:
As reported in Bug ID #3793 (from [EMAIL PROTECTED]) following still
happens (taken from [EMAIL PROTECTED], 2000-12-07 and veryfied by
[EMAIL PROTECTED], 2001-11-25):
1) "session.gc_maxlifetime" does not work - I set this to 60 sec, but I can
read values from the session even when time expired. (I start the session
and then I wait
more than 60 sec before calling other script)
2) When I set "session.gc_probability = 100" in php.ini, ALL other session
files are deleted (only one session can be used at the time - if 2 clients
are connected to
server, the second client deletes session of the first client, etc.). .
My Comment:
To (1): This may be intended when using cookies! Because if
session.cookie_lifetime is =0 (until browser is restarted) finding a valid
SID in the cookie may prevent the gc from destroying the session data. (The
doc leves this open).
To (2): For testing I've set "session.gc_probability = 50" but the effect
is the same. As soon as the gc runs, all other session-files are deleted.
gc_maxlifetime has no influance.
[EMAIL PROTECTED] wrote that it may have to do with 'atime' and I would think
so too. I would consider to use 'mtime' (maybe as fallback). Even the
PHP-manual makes restriktions to 'atime': "Some Unix filesystems can be
mounted with atime updates disabled to increase the performance."
