memcachedb's Issues

increment key issue memcachedb-1.0.0.beta

php example:
<?php
$memcache = new Memcache;
$memcache->addServer('localhost', 21201);

$memcache->set('key1',7);
$memcache->increment('key1',2);


echo "key1=>".$memcache->get('key1') ."\n";

$memcache->increment('key1',2);

echo "key1=>".$memcache->get('key1') ."\n";
?>

result:

key1=>9
PHP Notice:  get(): marked server 'localhost:21201' as failed in ...
key1=>


telnet differencies:

Telneting into memcached 1.2.2

root@x:~# telnet localhost 11211
Trying 127.0.0.1...
Connected to localhost
Escape character is '^]'.
add aa 0 0 1
9
STORED
incr aa 1
10
get aa
VALUE aa 0 2
10
END



Telneting into memcachedb 1.0.0
root@x:~# telnet localhost 21201
Trying 127.0.0.1...
Connected to localhost
Escape character is '^]'.
add aa 0 0 1
9
STORED
incr aa 1
10
get aa
VALUE aa 0 1
10
END



There's a notable difference between the response from the servers on the
second get
memcached replies with "VALUE aa 0 2"
memcachedb replies with "VALUE aa 0 1" (number of bytes differs)

when adding an existing key memcached server failed

What steps will reproduce the problem?

From php connect to memcachedb via Memcache() class 

1. add a key with a value
2. try to add again the same key 


What is the expected output? What do you see instead?
-normaly this should return false

Result: PHP Notice:  add(): marked server 'localhost:21211' as failed in ...

db_checkpoint等memcachedb私有命令怎么用？

hi，您好！

     我用java开源的memcached client访问memcachedb,象 db_archive ，db_ismaster，db_checkpoint等memcachedb私有命令怎么用？

     要扩展memcached client还是memcachedb也提供同样的API来调用？


     期待您的回复，谢谢！

Errors with memory pool size over 2G

What version of the product are you using? On what operating system?
- CentOS 5.2 x84_64
- 15GB of RAM
- libevent-1.4.9-stable.tar.gz
- db-4.7.25.tar.gz
- memcachedb-1.2.0.tar.gz

We attempted to run the memcachedb daemon with 12GB of memory in cache. 
After seeing revision r94 about a bugfix for allocating more than 2GB in
the memory pool, we decreased our cache size to 2GB.  Here are some of the
errors we saw:


"Failed to write, and not due to blocking: Broken pipe"    
dbp->put: Cannot allocate memory
unable to allocate space from the buffer cache

Is the bug fix in r94 only for 1.2.1-beta?  Also, do you recommend the beta
version over the stable 1.2.0?  Finally, with this bug fix, what is the
maximum allowed size for the memory pool?

Thanks,
Bryan

memcachedb的命中问题

您好！

    如果我增加一台memcachedb服务器，根据memcached client哈希算法，原来在第一台memcachedb上的数据可能会被指向到这台新的服务器，这样一来就存在命中问题，等价于数据丢失，如果是memcached到没有什么，但如果是db的话，就有问题了，不知道我说的问题存不存在？

   期待您的回复，谢谢！

log files issue

same configuration like Issue 2

1. limited space on disk .. like 200 mb
2. set some 50.000 - 75.000 keys with values
3. these keys have some index that is also a key here

database is in env/
here are also some log files 10 mb each that sems to only grow in number 
so my free space in became 0
to delete a key from memcachedb I also need to change value on the index key.
but index key value dosn't change, in result my script run to infinite loop.

If I delete something and make some free space , my script works fine

question is: can this memcachedb log be deactivated? if yes, how?

>9 SERVER_ERROR out of memory

What steps will reproduce the problem?
1. ./configure && make && make install
2. /usr/local/bin/memcachedb -l 127.0.0.1  -u nobody -vv -f
/var/cache/memcachedb/default.db -H /var/cache/memcachedb 
3. <9 set b0779a1737d196b5536656a5321243aade7df486 0 86400 13989

What is the expected output? What do you see instead?

The expected output is:

>9 STORED
<9 connection closed.

I get:

>9 SERVER_ERROR out of memory

What version of the product are you using? On what operating system?

memcachedb-1.0.2-beta with:

Kubuntu 7.10, db4.6, libevent (the latest in Ubuntu).

Please provide any additional information below.

I'm trying to use memcachedb as a session storage for PHP, using the
memcache extension of PHP. Something like this works:

<9 set 47e33a215d3f30195bfc511174299c0572ada092 0 86400 332
>9 STORED

but this doesn't:

<9 set 47e33a215d3f30195bfc511174299c0572ada092 0 86400 13961
>9 SERVER_ERROR out of memory

I tracked the problem up to memcachedb.c line 1154:

    it = item_alloc(key, nkey, flags, vlen+2);

    if (it == 0) {
        out_string(c, "SERVER_ERROR out of memory");
        /* swallow the data line */
        c->write_and_go = conn_swallow;
        c->sbytes = vlen + 2;
        return;
    }

but after that I'll need some help. Thanks.

SIGSEGV, Segmentation fault in __ham_get_h_ffactor ()

What steps will reproduce the problem?

1. Install & run

export LD_LIBRARY_PATH=/usr/local/BerkeleyDB.4.7/lib:/usr/local/lib
memcachedb -p21201 -d -r -u raru -H /home/raru/dev/local/tmp/memcahedb/test -N 
-v

2. Test with telnet

telnet localhost 21201
set test 0 0 4
get test

What is the expected output? What do you see instead?

Set seems to work.
But instead of getting "test" value I get a SEGFAULT and memcachedb process 
dies.

Multi-get bug

BUG:

trying to get multiple keys from memcachedb in one call, it returns only
the first key value

php test:

<?php
$memcache = new Memcache;
$memcache->addServer('localhost', 21211);

$memcache->set('key1','val1');
$memcache->set('key2','val2');
$memcache->set('key3','val3');
$memcache->set('key4','val4');

echo "\nnormal get";
echo "\nkey1=>".$memcache->get('key1') ."\n";
echo "key1=>".$memcache->get('key2') ."\n";
echo "key1=>".$memcache->get('key3') ."\n";
echo "key1=>".$memcache->get('key4') ."\n";

$keys = array();
$keys[]= 'key1';
$keys[]= 'key2';
$keys[]= 'key3';
$keys[]= 'key4';
echo "\nmulti get";
echo "<pre>";
print_r($memcache->get($keys));
echo "</pre>";
?>

result:


normal get
key1=>val1
key1=>val2
key1=>val3
key1=>val4

multi-get
<pre>Array
(
    [key1] => val1
)

Memcachedb产生的db文件不会减小

Memcachedb产生的db文件怎么不会变小？我循环插入50万条数据，
然后过了一段时间挨个删除，结果db文件停在44M就没有变化，
这是什么原因呢？望高手赐教！

MemcacheDB的日志是否可以删除？

压缩了之后每天也有不少的量，硬盘又小。。
是否可以删除呢？还是可以删除多少天之内的呢？
