### Possible Solutions
I think the problem here is that on db_mode == 2 pua never search for the pua record if no
etag is set

I don't remember. It was long time ago. Perhaps there has been some
mailing list discussion related to the commit.
Why on PUA_DB_ONLY there's no call to
``get_record_puadb``
https://github.com/kamailio/kamailio/commit/6822ff45e931ad3e93b22ebf7d1beb3…
There is call to ``get_record_puadb``:
```
if (dbmode==PUA_DB_ONLY)
{
if (publ->etag) {
memset(&dbpres, 0, sizeof(dbpres));
dbpres.pres_uri = &pres_uri;
dbpres.watcher_uri = &watcher_uri;
dbpres.extra_headers = &extra_headers;
presentity = get_record_puadb(publ->id, publ->etag,
&dbpres, &res);
}
}
```

@juha-h
There is call to ``get_record_puadb``:
Well I mean if ``publ->etag`` is NULL, the previous behavior was to call it always
```
if (dbmode==PUA_DB_ONLY)
{
memset(&dbpres, 0, sizeof(dbpres))
dbpres.pres_uri = &pres_uri;
dbpres.watcher_uri = &watcher_uri;
dbpres.extra_headers = &extra_headers;
presentity = get_record_puadb(publ->id, publ->etag, &dbpres, &res);
}

pua - db_mode set to 0. This stops multiple states for
a single dialog (early, trying, confirmed and terminated) from showing in the presentity
table. I suspect this is a bug?
I still see this behavior and I think is related to this code since pua_dialoginfo never
sets etag when calling ``send_publish()``

I don't remember publish details, but if there is no etag, it is the
first publish and therefore it doesn't make sense to get the record from
db.

Then isn't it a bug in pua_dialoginfo?
If I remember correctly, first PUBLISH is sent without SIP-If-Match
header (containing etag), then etag is obtained from 200 OK's SIP-ETag
header and placed in SIP-If-Match header of following PUBLISH requests.

I don't think so. The purpose of E-Tag is to identify a state of the resource. If the
resource changes a new E-Tag has to be generated. [Generating
Entity-tags](https://tools.ietf.org/html/rfc5839#page-20)
In this case, pua_dialoginfo is changing the state so a new E-Tag has to be generated and
the record in db in this case must be updated. Not insert a new one.

That is about notifier behavior in subscribe/notify exchange and does
not deal with publish requests.

Ok. Then it should be this one. https://tools.ietf.org/html/rfc3903#section-8.2
The ``SIP-If-Match`` is missing from any PUBLISH. pua is not doing the same depending on
db_mode.
Even if ``etag`` is not set we need to search for previous record. OK, first PUBLISH will
never have a record but the rest yes.
So, with db_mode == 0:

I no longer see more than one record in pua table and PUBLISH now have the proper
``SIP-If-Match`` header matching the previous value in 200 OK

other side effect is that only the last record of DIALOG_PUBLISH.* gets removed properly
and the rest of records just are hanging there until max dialog duration time expires, by
default 3600 secs

I cannot reproduce the issue. In my tests after the first publish the rest
do have SIP-If-Match header, for example:
```
T 2020/07/30 20:57:06.251465 127.0.0.1:50064 -> 127.0.0.1:5080 [AP] #20

That happens because etag param is included in the json request:

```
Why can't pua_dialoginfo do the same?

Isn't it so that pua module send_publish function sends exactly such publish as
specified in its parameters? One of the parameters is etag. So if first or subsequent
publish requests contain SIP-If-Match header is up to what kind of parameters send_publish
has got.

Sorry @juha-h but I don't get your point.
If a pua_* module execute send_publish() and etag is not set pua has to search anyway for
that ``ua_pres_t`` in the db. So it would be updated. If not, we are getting a record for
every state, SIP-If-Match in later PUBLISH of the same dialog is missing and only the last
record gets removed when the dialog is finished.
All of that doesn't happen with
https://github.com/kamailio/kamailio/commit/da7f7ef082e28f81893ec06081358a9…
Every **pua_*** module that uses pua.send_publish() except **pua_rpc** doesn't set
etag parameter.
* **pua_bla**
* **pua_dialoginfo**
* **pua_usrloc**
* **pua_xmpp**
So I don't get what you want to achieve. This was a bug that users reported and I had
suffered.

Why don't these other modules keep track of the etag received from 200
ok to the initial publish and use it in subsequent ones?
Are you sure that the change you made does not have any negative
consequences to pua_rpc user that saves the etag from the initial
publish and uses it in subsequent ones?
May be there was some real reason when I made the commit many years
ago.

I cannot be sure 100% but from what I understand if you set etag... it has the same
behavior than previously.
If is the first PUBLISH, there's no record, so no changes in logic.
Change is merged already do you detect any regression?

I can test when the merge is backported to 5.4, since I don't at present
have a live master system.
