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.
No 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
