Re: [OpenSIPS-Users] CACHEDB_MEMCACHED Module - libmemcached undefined symbol issue

[Maciej Bylica]

Hi,

Don't know there the problem was located. Port  was only utilized by
memcached process.
Anyway i hope there are no issues within the memcached module code.

Thanks
Maciej.

Hi Bogdan,

Thanks for the reply.

It seems it is related to the key, it doesn't matter which query
is it.
First query on the second key does not change anything.
I've just added additional key 49101112233 and it works (query was
fired), but 49331112233 does not.

Thanks
Maciej.

Hi Maciej,

Thanks for the detailed report.

Do you think the error is related to the key you are trying to
fetch or is it related to the simply being the second query
you perform ?  What if you perform from the very beginning a a
query on the second key ?

Hello
As i mentioned before memcached is already installed. I am
using innodb_memcache.containers to implement memcached as a
plugin.

netstat -plnt | grep 

tcp 0  0 127.0.0.1: 
0.0.0.0:*   LISTEN  18421/mysqld


Everything looks fine i have full transparency, data provided
by memcached CLI (telnet) are seen inside innodb table and
vise versa.
I am using the latest 2.2.2 git opensips rel. and memcached
module loaded:

loadmodule "cachedb_memcached.so"

modparam("cachedb_memcached",
"cachedb_url","memcached:default://localhost:,127.0.0.1/
")

The script i am using is just the basic one, without any
additional configuration.
Inside the script there is following operation provided:

cache_fetch("memcached:default","$tU",$avp(i:601));

Innodb table contains following data:

+-+-+--+--+--+

| id   | num | c3   | c4   | c5   |

+-+-+--+--+--+

| 49221112234 | 49221112234 |0 |2 |0 |

+-+-+--+--+--+

Now, i am sending INVITE with tU = 49121112233 and getting
proper behavior which means:
- no error inside the opensips.log, xlog followingcache_fetch
returns correct $avp(i:601) - mysqld.log shows

<95 get 49121112233

>95 sending key 49121112233

>95 END

but really strange is that calling tU = 49221112233 is
causing quite opposite results:
- following error is shown

DBG:core:cachedb_fetch: from script [memcached] - with grp
[default]

ERROR:cachedb_memcached:wrap_memcached_get: Failed to get:
SYSTEM ERROR

- no mysqld debug is produced

The last one example(tU = 49221112234)is failing with the
same error.

Memcached is loaded with all those data

Connected to localhost.

Escape character is '^]'.

get 49221112233

END

get 49221112234

VALUE 49221112234 0 11

49221112234

END

but because of some reasons memcached module is not utilized.
As aforementioned, opensips script does not have any $rU
filtering setup, so should query for any data it is asked for.
Maybe i am wrong with some of my assumptions or the way
memcached is configured, so kindly help me to understand
where the problem is located.

Hi Maciej,

Thanks for the detailed report.

Do you think the error is related to the key you are trying to fetch or 
is it related to the simply being the second query you perform ?  What 
if you perform from the very beginning a a query on the second key ?

but because of some reasons memcached module is not utilized.
As aforementioned, opensips script does not have any $rU filtering 
setup, so should query for any data it is asked for.
Maybe i am wrong with some of my assumptions or the way memcached is 
configured, so kindly help me to understand where the problem is located.


Thanks
Maciej.

Hi Maciej, As I see, you are manually compiling and
installing the memcached stuff - any special reason for doing
that ? (versus using packages) As the problem seems to be in
the lib, not in the OpenSIPS module. Regards,

Re: [OpenSIPS-Users] CACHEDB_MEMCACHED Module - libmemcached undefined symbol issue

[Maciej Bylica]

Hello

As i mentioned before memcached is already installed. I am using
innodb_memcache.containers to implement memcached as a plugin.

netstat -plnt | grep 

tcp0  0 127.0.0.1:  0.0.0.0:*
LISTEN  18421/mysqld


Everything looks fine i have full transparency, data provided by memcached
CLI (telnet) are seen inside innodb table and vise versa.

I am using the latest 2.2.2 git opensips rel. and memcached module loaded:

loadmodule "cachedb_memcached.so"

modparam("cachedb_memcached", "cachedb_url","memcached:default:
//localhost:,127.0.0.1/")

The script i am using is just the basic one, without any additional
configuration.
Inside the script there is following operation provided:

cache_fetch("memcached:default","$tU",$avp(i:601));

Innodb table contains following data:

+-+-+--+--+--+

| id  | num | c3   | c4   | c5   |

+-+-+--+--+--+

| 49121112233 | 49121112233 |0 |3 |0 |

| 49221112233 | 49221112233 |0 |1 |0 |

| 49221112234 | 49221112234 |0 |2 |0 |

+-+-+--+--+--+

Now, i am sending INVITE with tU = 49121112233 and getting proper behavior
which means:
- no error inside the opensips.log, xlog following cache_fetch returns
correct $avp(i:601)
- mysqld.log shows

<95 get 49121112233

>95 sending key 49121112233

>95 END

but really strange is that calling tU = 49221112233 is causing quite
opposite results:
- following error is shown

DBG:core:cachedb_fetch: from script [memcached] - with grp [default]

ERROR:cachedb_memcached:wrap_memcached_get: Failed to get: SYSTEM ERROR

- no mysqld debug is produced


The last one example(tU = 49221112234)is failing with the same error.


Memcached is loaded with all those data

Connected to localhost.

Escape character is '^]'.

get 49221112233

VALUE 49221112233 0 11

49221112233

END

get 49221112234

VALUE 49221112234 0 11

49221112234

END


but because of some reasons memcached module is not utilized.
As aforementioned, opensips script does not have any $rU filtering setup,
so should query for any data it is asked for.
Maybe i am wrong with some of my assumptions or the way memcached is
configured, so kindly help me to understand where the problem is located.
