Werner you never mentioned which version of memcache you're using. For
what it's worth, it seems things differ between 1.4.0 and 1.2.6.
(Haven't peeked at 1.3.x series.)
1.2.6 will allocate a new slab if memory is available, before grabbing
the last item off the free list (which may or may not ha

Sorry. I started this before 1.4 has been out, and as we are running
in
production environment, we are using 1.2.6
I don't know, I'm just guessing. :-) But there's really only two scenarios
that are possible:
1) Ajeet's test is broken, he doesn't really store 5 million unique items,
and fails to detect the cache misses.
2) Stats is broken, Ajeet stores 5 million unique items, but the server
counts them incorr
Hi,
This is not an important question, but I wonder the answer.
When I develop websites by using memcache, I also use it for spam
checking.
For example; When someone post a comment, or report something, or
search something, I create a memcache object and set an expiration
time, i.e. 5 seconds.
Another question you might want to ask is how are you going to handle it if
the item has been evicted from the cache? Someone could be spamming you and
you wouldn't catch it.
Granted, that would have to be a cache with a high-eviction rate but it's
still a possibility you might want to consider.
No, this is not very expensive. We use memcached for a lot of our
rate-control here.

Well, I'd say that for double-post and spam control, it's not a big
problem if sometime it doesn't work. I mean, with this kind of
algorithm he already accept one spamming message, so two is not a
problem.

Granted, Colin, but I wouldn't want anyone coming across a simple
implementation like this and then expand upon it without the realization
that memcached is not a persistent data store.

This sort of information is inherently fairly transient, though, I'd say.
Unless you're getting a huge amount of spam from a lot of different user
IDs or your cache is already running very near to capacity (in which cases
you already have bigger problems), I'd say it should work in the great
major
Maybe more esoteric options should come through a single flag, ala
ssh, where you can have "-o UnusualOption=foo". That reduces the
number of single-letter flags in the command-line flag namespace.

Is there any one who could help me ?
At least few links which gives little more information. Is it a wrong
place to ask for this version of memcached ?

Aaron,
That's a great suggestion. I'm willing to write the patch accordingly
if I get the green light indicating we can get this into the trunk.
Thanks,

Are you having a problem with performance, fragmentation and stuff in
the current memcached version?

I don't think anyone supports that version. We kind of look at it
as a research project. Fac

Do note that we had a -o issue and some changes t

Hi guys,
I have been trying to diagnose a memcached segmentation fault. It is
running on a 32 bit Linux 2.6.20 build (Gentoo). The memcached server
is being connected through the standard PHP (5.2.6 module to Apache 2)
client. After a few reloads of the provided script, the server will
crash (
