ultramemcache's Issues

Not gevent compatible?

I see ultrememcache is mentioned in the gevent page:
https://github.com/SiteSupport/gevent/wiki/Projects

However running a few parallel greenlets using umemcache breaks it.. see errors below.
The test script uses python-memcached as a baseline to compare.

Or maybe I'm just doing something wrong?

Thanks.

import gevent
from gevent import monkey; monkey.patch_all()
from gevent.pool import Pool

import hashlib
import memcache
import umemcache

HOST = '127.0.0.1:11211'

mc_pymemcache = memcache.Client([HOST])
mc_umemcache = umemcache.Client(HOST)
mc_umemcache.connect()

def test(mc):
    for i in xrange(1000):
        key = hashlib.md5(str(i)).hexdigest()
        mc.set(key, "TEST VALUE")
        mc.get(key)

def concurrize(mc):
    pool = Pool(10)
    jobs = [pool.spawn(test, mc) for i in range(10)]

configurable item size + wrong maths

The default max size for memcache items is 1 MB, not 100,000 bytes, so this is wrong I think:

https://github.com/esnme/ultramemcache/blob/master/lib/Client.cpp#L209

It should be 1024 * 1024

Also, it seems that the 1MB limit is now configurable:

https://code.google.com/p/memcached/wiki/ReleaseNotes142#Configurable_maximum_item_size

maybe umemcache should let memcache itself deal with this issue instead of raising an error when > 1MB ?

umemcache fails to build if "-Werror=format-security" flag is used.

...

./python/umemcache.cpp:870:62: error: format not a string literal and no format arguments [-Werror=format-security]

...

Does it not supports connect via unix domain socket?

Start process

memcached -s /tmp/mc.sock

Test code

import umemcache

mc = umemcache.Client('unix:/tmp/mc.sock')
mc.connect()

print mc.set('a', 'b')

Got exception

Any plan for cluster support?

Any plans to support a list of server hostnames/ports as the input to Client()?

Heroku support

I would like to use ultramemcache on the Heroku hosting framework.
The requirements are that the client will use the binary protocol and support SASL.
Does ultramemcache support those? and if not, can the support be added?

Connection and command timeout

Hi guys,

This is a great project, that will help a lot when moving to greenlets in the future.

While evaluating ultramemcache I was looking for a way to specify the connection timeout and also the command timeout, but did not find such thing. Is there a way to do this?

In case this is not part of the lib yet, can it be added?

Many thanks,
Ciprian

gets_multi behavior seems odd

Getting some weird behavior when trying to use gets_multi (normal gets+cas works fine).
I might be doing it wrong?

import umemcache
mc = umemcache.Client("127.0.0.1:11211")
mc.connect()
mc.set("test1", "1")
mc.set("test2"," 1")
d =  mc.gets_multi(["test1", "test2"])
print mc.cas("test1", "2", d["test1"][2])
##
print mc.gets("test1")
print mc.gets("test2")
print mc.gets_multi(["test1", "test2"])

output:

EXISTS
('1', 0, 2290L)
(' 1', 0, 2291L)
{'test1': ('1', 0, 140734726660512L), 'test2': (' 1', 0, 140734726660512L)}

There is something fishy about the cas_ids for the results in gets_multi. Via telnet:

gets test1 test2
VALUE test1 0 1 2290
1
VALUE test2 0 2 2291
 1
END

Handling reconnections

Right now with a connected client, if the server is restart, the client will break. IOW if the server blips the connector is broken.

It's happening to us in the Django memcached pool I wrote: https://github.com/mozilla/django-memcached-pool

Since I am keeping open connections, it's important for me to be able to respawn the connections when the server has restarted.

I am working on a ReconnectClient class that attempts to reconnect and replay the query in case there's an error.

@jskorpan are you interested in this feature for integration in umemcache ?

Compiling or installing through pip errors

Not sure if anyone else has tested this, but after the repackage for pip, I can't seem to install this anymore. While running the build through pip, gcc exits with the error: "error: expected constructor, destructor, or type conversion before ‘*’ token".

Django integration

It can be nice if this project will integrate with Django through a custom cache backend.

See here for how https://docs.djangoproject.com/en/dev/topics/cache/#using-a-custom-cache-backend

Python 3 supports

Are you interested by a Python 3 support for this lib?

CAS doesn't work with Couchbase 2.0

Ubuntu 12.04 64-bit. We were using ultramemcache quite happily with Couchbase 1.8.1. I seem to recall 1.8.1 generating relatively short CAS values (maybe 5 digits). 2.0 is now generating large CAS values, larger than 32 bits, which may be what's causing the problem. CAS does work correctly when passing zero for the CAS value. Any chance of this getting fixed?

Operation Failed silents the C error

I get some Operation failed errors, but I am not sure what's going on

in this line: https://github.com/esnme/ultramemcache/blob/master/python/umemcache.cpp#L352

I am wondering, is there a reason why you don't try to get the error with self->client->getError() ?

Build failure due to GCC deprecation warnings

Saw this when installing via pip in a Travis.ci build. I was able to resolve it by setting the env variable CFLAGS="-Wno-error", but figured I'd post this as a reference for the warnings. Thanks!

Pipeline tests fail

After merge the pipeline tests are failing, it's being looked into!

A C++ client test implementation.

Is it possible to have a client test implementation like the one in python please ?
In the README or in the ./test/ directory.
Something like this... idk :

#include <iostream>
#include "../lib/Client.h"

int main(void)
{
    SOCKETDESC scktd;

    Client memcache_client(&scktd);

    if(memcache_client.connect("127.0.0.1", 11211))
    {
        std::cout << "[+] Success connection has been etablished with the memcached server !";
        //memcache_client.set("key","my value !");
    }
    else
    {
        std::cout << "[-] Error connection with memcached server !";
    }
    std::cout << "[-] Test !\n";

    return 0;
}

Please help !

Reconnect

How do I properly reconnect when the memcached server has been restarted?

I've tried closing the connection:
server.close()
server.disconnect()

but I always get the error:
umemcache: Connection reset by peer
Client can not be reconnected

when running server.connect()

Support SASL

Can you add SASL support?
