Hello,

db_fetch_rows is about setting the value of how many rows to be loaded at once. 0 is a special value meaning that this limit is not set and all rows are loaded at once. db_fetch_rows is common parameter for other modules (e.g., usrloc) with same kind of behaviour, so I would not change the behaviour of db_fetch_rows.

For what you need, maybe db_mode should get a new value -- this is the parameter that controls the relation with database. However, if the write modes provided by db_mode are something that worth combining with the "no-read" mode, then a new parameter can be added, like db_skip_load.

Cheers,
Daniel

Further to this, I have created a pull request that I think should behave better.

Hey All,

Im just after someone else thoughts on if this is a bug.

After reading : http://kamailio.org/docs/modules/3.3.x/modules_k/dialog.html#idp148408
Im lead to understand that setting modparam("dialog", "db_fetch_rows", 0)
should instruct the dialog module to write dialogs to the DB, but not bother loading them on startup. This sounds like what I'm after.

However ever time I set the value to 0, dialogs are still loaded from the DB.

a quick dig in the source takes me to the function

select_entire_dialog_table in dlg_db_handler.c
this chunk of code does not appear to properly implement " if fetch_num_rows == 0 then do nothing "

Im after a couple of things from you guys.

a) validation that my understanding of what SHOULD happen is correct

b) possibly validating that I'm not crazy, and this is actually a bug :)
