Hi,

it is not a problem of the sqlite file:

sqlite> .schema userpush
CREATE TABLE userpush (
    key_name TEXT,
    "key_type" INTEGER,
    value_type INTEGER,
    key_value TEXT
);
sqlite> insert into userpush ('key_name') values ('test');
sqlite> select * from userpush;
test|||
sqlite>

And the file itself has 666 as rights, so everyone is allowed to write to it. (at the moment)

Betreff: RE: [SR-Users] Kamailio 5.6.4 and htable dbmode=1

Hello,

 

ERROR: db_sqlite [dbase.c:528]: db_sqlite_commit(): sqlite commit failed: attempt to write a readonly database
ERROR: db_sqlite [dbase.c:177]: db_sqlite_cleanup_query(): finalize failed: attempt to write a readonly database
ERROR: htable [ht_db.c:668]: ht_db_delete_records(): failed to delete db records in [userpush]
ERROR: db_sqlite [dbase.c:528]: db_sqlite_commit(): sqlite commit failed: attempt to write a readonly database

This looks that the error is not on the Kamailio side, but your database is somehow not working correctly.

 

Have you tried to open the database with the sqlite command line shell and execute an INSERT or similar? If it also fails, there must be something wrong on the DB side.

 

Cheers,

 

Henning

Hi Daniel,

thank you for your response.
As you can see in the provided debug output:

kamailio[]: DEBUG: htable [ht_api.c:1046]: ht_table_spec(): htable

[callpush] - dbmode [1]

kamailio[]: DEBUG: htable [ht_api.c:1027]: ht_table_spec(): htable

[callpush] - dbtable [userpush]

kamailio[]: DEBUG: htable [ht_api.c:1036]: ht_table_spec(): htable

[callpush] - expire [86400]

kamailio[]: DEBUG: htable [ht_api.c:1041]: ht_table_spec(): htable

[callpush] - size [10]

dbmode is set to 1 in the config:

modparam("htable", "db_url", "sqlite:////etc/kamailio/htable.sqlite")

...

modparam("htable", "htable", "userpush=>size=3;autoexpire=600;dbtable=userpush;dbmode=1")

If I execute

kamcmd htable.store userpush

I get
Ok. Htable successfully stored to DB.

But the table is still empty!!!

In the log I found:
ERROR: db_sqlite [dbase.c:528]: db_sqlite_commit(): sqlite commit failed: attempt to write a readonly database
ERROR: db_sqlite [dbase.c:177]: db_sqlite_cleanup_query(): finalize failed: attempt to write a readonly database
ERROR: htable [ht_db.c:668]: ht_db_delete_records(): failed to delete db records in [userpush]
ERROR: db_sqlite [dbase.c:528]: db_sqlite_commit(): sqlite commit failed: attempt to write a readonly database

Ok.
But I can not see this entries if I shutdown kamailio.

And:
-rw-rw-rw-  1 kamailio root 16384 Jul 13 16:14 htable.sqlite


I never used:

modparam("db_sqlite","db_set_readonly" ...

I also restarted kamailio. no difference.

Now more errors then before:
It is not written at shutdown. (no messages)
It is not written (live) (with error messages, but why it is readonly?)
The message of kamcmd is wrong (says Ok but it failed)

Best regards,

Bernd

Hello,

is dbmode=1 in htable definition?

If you run rpc command htable.store for the htable, are the records

saved to database?

Cheers,

Daniel

Hi,

I just tried to use sqlite and htable to load and save the values.

At start I can see in the log, that all parameters are correct and

that htable want to load the values from the table.

No errors.

But if I stop kamailio, nothing is written to the tables.

At start I can see:

Ok, the file is empty, but it tries to load the data from the table.

The table looks like:

sqlite> .schema userpush

CREATE TABLE userpush (

        key_name TEXT,

        "key_type" INTEGER,

        value_type INTEGER,

        key_value TEXT

);

I checked the source code and I saw that destroy() should be called.

Inside is ht_db_open_con() called before ht_db_sync_tables(), were it

happens.

But I can even not see the debug message from ht_db_open_con() :

LM_DBG("database connection opened successfully\n")

and also not

LM_ERR("failed to connect to the database\n");

For me it looks like, that the destroy() function is not called.

Even with debug=3, I can only see:

systemd[]: Stopping kamailio.service - Kamailio - the Open Source SIP

Server...

kamailio[]: INFO: <core> [main.c:854]: sig_usr(): signal 15 received

systemd[]: kamailio.service: Deactivated successfully.

systemd[]: Stopped kamailio.service - Kamailio - the Open Source SIP

Server.

I stopped kamailio with

systemctl stop kamailio

I'm sure that something was inside the htable before I stoped kamailio:

{

        entry: 0

        size: 1

        slot: {

                {

                        name:

07db580a6c13e798a5acc0d123d6e957897c8650b43f99d6d5cb9c2cb5ba4fa4

                        value:

3a28dcb73eb65722df5a261983b7692cecdca482bf8725032e46a0c6b89fb355

                        type: str

                }

        }

}

Any further ideas?

Best regards,

Bernd
