lighttpd forum XCache > XCache not caching?

Hi,

I installed XCache a few days ago and it looks like it is configured
properly and it is loaded into PHP too. However when I visit the admin
section, I don't see anything cached. I've compared it to the demo
installation of xcache and mine looks empty. Please see the attached
screenshot.

I've never installed an opcode cacher before so I am not exactly sure if
there is a problem or not. But as I can't see anything cached, I am
slightly worried there is something wrong :)

My configuration is as follows:

--------

[xcache-common]
;; install as zend extension (recommended), normally
"$extension_dir/xcache.so"
zend_extension =
/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/xcache.so

[xcache.admin]
xcache.admin.auth = On
xcache.admin.user = "x"
xcache.admin.pass = "x"

[xcache]
; ini only settings, all the values here is default unless explained

; select low level shm/allocator scheme implemenation
xcache.shm_scheme =        "mmap"
; to disable: xcache.size=0
; to enable : xcache.size=64M etc (any size > 0) and your system mmap
allows
xcache.size  =                5M
; set to cpu count (cat /proc/cpuinfo |grep -c processor)
xcache.count =                 1
; just a hash hints, you can always store count(items) > slots
xcache.slots =                8K
; ttl of the cache item, 0=forever
xcache.ttl   =                 0
; interval of gc scanning expired items, 0=no scan, other values is in
seconds
xcache.gc_interval =           0

; same as aboves but for variable cache
xcache.var_size  =            5M
xcache.var_count =             1
xcache.var_slots =            8K
; default ttl
xcache.var_ttl   =             0
xcache.var_maxttl   =          0
xcache.var_gc_interval =     300

xcache.test =                Off
; N/A for /dev/zero
xcache.readonly_protection = Off
; for *nix, xcache.mmap_path is a file path, not directory.
; Use something like "/tmp/xcache" if you want to turn on
ReadonlyProtection
; 2 group of php won't share the same /tmp/xcache
; for win32, xcache.mmap_path=anonymous map name, not file path
xcache.mmap_path =    "/dev/zero"


; leave it blank(disabled) or "/tmp/phpcore/"
; make sure it's writable by php (without checking open_basedir)
xcache.coredump_directory =   "/tmp/phpcore/"

; per request settings
xcache.cacher =               On
xcache.stat   =               On
xcache.optimizer =            On

[xcache.coverager]
; per request settings
; enable coverage data collecting for xcache.coveragedump_directory and
xcache_coverager_start/stop/get/clean() functions (will hurt executing
performance)
xcache.coverager =          Off

; ini only settings
; make sure it's readable (care open_basedir) by coverage viewer script
; requires xcache.coverager=On
xcache.coveragedump_directory = "/tmp/phpcore/"

--------

$ php -v
PHP 5.2.4 (cli) (built: Sep  7 2007 00:29:46)

I specify the same php.ini in the fcgi block too so it should have the
xcache in it too.

Is there a way I can use to test whether the caching works or not?


Thanks.

Probably, you added the xCache library just to command-line php.
Are you sure that your web-server is also using the xCache config?
