Hi,
I am very glad to have the new del_uri_param function. This was a
common problem of mine and it is great not to have to use regex to do
this. However, while implementing this I have run into some strange
behavior by the function when the URI param being deleted does not exist.
In my case I am using the dialog module and attempting to remove a URI
param just after the dialog creation. When the function does not find
the URI param, it causes the dialog to immediately be destroyed and
all message processing stops, including exiting the script.

The logs indicate that a DLG_EVENT_TDEL is being raised which, when
the dialog is still in UNCONFIRMED state, causes the dialog to be
destroyed. It’s not clear to me how or why the del_uri_param function
could be doing this, especially as a transaction hasn’t even been
created for the message yet in this case. I’m not sure what effect
this would have if the dialog is in other states or at other times
during the call.
It took me a while to realize it was the del_uri_param function
causing this, as it seems so strange. But I have verified that when I
remove the function, or when I verify the URI param exists before
calling the function, everything is fine. That workaround works
perfectly well, but it seemed such strange and catastrophic error
behavior to drop the entire message that I wanted to report it anyway
to see if anything needed to be addressed.
Call traces can be found here: https://pastebin.com/9FnmJCD9
You will see the same INVITE is offered multiple times as OpenSIPS is
not responding after dropping the previous requests and dialog.
Thanks,
Ben Newlin
