udp sessions in PHP

[Artur Ejsmont]

Hi there,

I cant find sufficient documentation for the udp support and i am a
bit confused.

Is it true that get command is not supported in udp mode or is it just
old versions?

I run 1.4.4 on debian (memcached -u root -vv) and connect to it from
command line like this:

echo $'stats\r\nquit\r\n' | nc -u localhost 11211

i get error like this in memcached output

29 SERVER_ERROR multi-packet request not supported

I can not force php to use memcache as session handler, im sniffing my
tcp and udp traffic on 11211 in/out and only see tcp connections. I
have set (memcache 2.2.5 module)

session.save_handler = memcache
session.save_path = "udp://x.x.x.x:11211"

and its still connection via tcp even that i can see udp in the
phpinfo output.

i thought this should work the same way as tcp just with no
guarantees.

Could anyone please point me to some documentation that could help me
get it working?

thanks

pecl/memcache (http://pecl.php.net/package/memcache/) 2.2.5 does not
support udp. The beta's do, but they're still buggy. No work has been
done on this module for ~1 year. pecl/memcached (http://pecl.php.net/
package/memcached/) is more stable and has more features, but has not
implemented udp yet.
