Hello list,
I have a special situation in which string characters of the "root-line"
of the notify-body are overwritten by Kamailio. In detail: the root-line
of the NOTIFY message sent to the subscriber looks like:
<dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info" version="1"
ll"
entity="sip:117090@10.16.10.99"> instead of
<dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info"
version="1"
state="full" entity="sip:117090@10.16.10.99"> In other words: the
string
state="full" is overwritten by space characters. Therefore the message
is no longer "valid" and the parser of the subscriber-user agent has
problems....
The exact scenario in my use case is, that user agents can subscribe the
events "presence" and "dialog" on Kamailio. The information about
presence and dialog-states is published to Kamailio by PUBLISH messages
from the user agents themselves. Kamailio does not have to generate this
information itself. In the following lines I have an excerpt of the
signalisation: 1) initial subscription of party A, 2) the responded
notification (without body) 3) subscription of party B 4) the responded
notification (with body) 5) a publish message of the subscribed party B
with actual dialog information and 6) the notification with body to the
subscriber A.

Debug information of Kamailio and information in the source code show
that the version number "00000000000" is a placeholder only, which
should be replaced with a valid version number. However, it seems that
there is a problem in handling these strings. The version number is
replaced, but in case that the version id is only one character long,
ten space characters are inserted- overwriting other information......
Can anybody comment this problem? Is this a bug of the
presence_dialoginfo- or another module?
Thanks in advance!
Regards,
Klaus
P.S. additional information from source code an debug output of
kamailio:
notify_body.c:
[...]
/* The version must be increased for each new document and is a 32bit
int.
As the version is different for each watcher, we can not set here the
correct value. Thus, we just put here a placeholder which will be
replaced by the correct value in the aux_body_processing callback.
Thus we have CPU intensive XML aggregation only once and can use
quick search&replace in the per-watcher aux_body_processing callback.
We use 11 chracters as an signed int (although RFC says unsigned int
we use signed int as presence module stores "version" in DB as
signed int) has max. 10 characters + 1 character for the sign
*/
[...]

presence_dialoginfo- or another module?
IIRC, the problem was reported before. I reviewed the code where the
aggregation happens several times but could not find a bug in the code.
So, we need a volunteer to review the code.

Hello list,
I have a special situation in which string characters of the "root-line"
of the notify-body are overwritten by Kamailio. In detail: the root-line
of the NOTIFY message sent to the subscriber looks like:
<dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info"
version="1" ll"
entity="sip:117090@10.16.10.99"> instead of
<dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info"
version="1"
state="full" entity="sip:117090@10.16.10.99"> In other words: the
string
state="full" is overwritten by space characters.
Is it by space or by the versios="1"? Maybe the email body encoding ate
the spaces, above looks like one space before 'll"'.
Cheers,
Daniel
Therefore the message
is no longer "valid" and the parser of the subscriber-user agent has
problems....
The exact scenario in my use case is, that user agents can subscribe the
events "presence" and "dialog" on Kamailio. The information about
presence and dialog-states is published to Kamailio by PUBLISH messages
from the user agents themselves. Kamailio does not have to generate this
information itself. In the following lines I have an excerpt of the
signalisation: 1) initial subscription of party A, 2) the responded
notification (without body) 3) subscription of party B 4) the responded
notification (with body) 5) a publish message of the subscribed party B
with actual dialog information and 6) the notification with body to the
subscriber A.

Debug information of Kamailio and information in the source code show
that the version number "00000000000" is a placeholder only, which
should be replaced with a valid version number. However, it seems that
there is a problem in handling these strings. The version number is
replaced, but in case that the version id is only one character long,
ten space characters are inserted- overwriting other information......
Can anybody comment this problem? Is this a bug of the
presence_dialoginfo- or another module?
Thanks in advance!
Regards,
Klaus
P.S. additional information from source code an debug output of
kamailio:
notify_body.c:
[...]
/* The version must be increased for each new document and is a 32bit
int.
As the version is different for each watcher, we can not set here the
correct value. Thus, we just put here a placeholder which will be
replaced by the correct value in the aux_body_processing callback.
Thus we have CPU intensive XML aggregation only once and can use
quick search&replace in the per-watcher aux_body_processing callback.
We use 11 chracters as an signed int (although RFC says unsigned int
we use signed int as presence module stores "version" in DB as
signed int) has max. 10 characters + 1 character for the sign
*/

New subject: SIP NOTIFY problem in 'presence_dialoginfo' module?
Hello Daniel,
The problem is, that the format shown in the original email message below
isnt original. Some space characters are deleted. I will write it in
another form:
Party A:
A-1) initial notification to a Subscribe message was without body (because
no information about the subscribed party was available)
A-2) publication of a dialog state with PUBLISH:
<dialog-info xmlns=[..] version="4" state="full" entity[..]>
A-3) publication of a dialog state with PUBLISH:
<dialog-info xmlns=[..] version="5" state="full" entity[..]>
A-4) second notification to a dialog state change (confirmed, PUBLISHed
with PUBLISH ad B-4 below):
<dialog-info xmlns=[..] version="1" ll" entity[..]>
Party B:
B-1) Initial notification to a Subscribe message:
<dialog-info xmlns=[..] version="00000000000" state="full"
entity[..]>
B-2) second notification to a dialog state change (confirmed, PUBLISHed
with PUBLISH ad A-2 above):
<dialog-info xmlns=[..] version="1" state="full"
entity[..]>
B-3) third notification to a dialog state change (terminated, PUBLISHed
with PUBLISH ad A-3 above):
<dialog-info xmlns=[..] version="2" state="full"
entity[..]>
B-4) publication of a dialog state with PUBLISH:
<dialog-info xmlns=[..] version="4" state="full" entity[..]>
So here you can (should) see that the full string-length of the
placeholder is used all time and in the situations above filled with space
characters.
Regards,
Klaus
Hello,

Hello list,
I have a special situation in which string characters of the
"root-line" of the notify-body are overwritten by Kamailio. In detail:
the root-line of the NOTIFY message sent to the subscriber looks like:
<dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info"
version="1"
ll" entity="sip:117090@10.16.10.99"> instead of
<dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info"
version="1"
state="full" entity="sip:117090@10.16.10.99"> In other words:
the
string state="full" is overwritten by space characters.
Is it by space or by the versios="1"? Maybe the email body encoding ate
the spaces, above looks like one space before 'll"'.
Cheers,
Daniel
Therefore the message
is no longer "valid" and the parser of the subscriber-user agent has
problems....
The exact scenario in my use case is, that user agents can subscribe
the events "presence" and "dialog" on Kamailio. The information
about
presence and dialog-states is published to Kamailio by PUBLISH
messages from the user agents themselves. Kamailio does not have to
generate this information itself. In the following lines I have an
excerpt of the signalisation: 1) initial subscription of party A, 2)
the responded notification (without body) 3) subscription of party B
4) the responded notification (with body) 5) a publish message of the
subscribed party B with actual dialog information and 6) the
notification with body to the subscriber A.

Debug information of Kamailio and information in the source code show
that the version number "00000000000" is a placeholder only, which
should be replaced with a valid version number. However, it seems that
there is a problem in handling these strings. The version number is
replaced, but in case that the version id is only one character long,
ten space characters are inserted- overwriting other information......
Can anybody comment this problem? Is this a bug of the
presence_dialoginfo- or another module?
Thanks in advance!
Regards,
Klaus
P.S. additional information from source code an debug output of
kamailio:
notify_body.c:
[...]
/* The version must be increased for each new document and is a 32bit
int.
As the version is different for each watcher, we can not set here
the
correct value. Thus, we just put here a placeholder which will be
replaced by the correct value in the aux_body_processing callback.
Thus we have CPU intensive XML aggregation only once and can use quick
search&replace in the per-watcher aux_body_processing callback. We use
11 chracters as an signed int (although RFC says unsigned int we use
signed int as presence module stores "version" in DB as
signed int) has max. 10 characters + 1 character for the sign
*/

New subject: SIP NOTIFY problem in 'presence_dialoginfo' module?
Hello,
you said that the publish is created by the phones in your case, not by
kamailio with pua_dialoginfo, right?
If yes, then one question for Klaus D. in this case ... the body is
build in pua_dialoginfo with the placeholder and presence_dialoginfo
expects that? I had not dug in the code yet, just double-checking here.
Thanks,
Daniel

Hello Daniel,
The problem is, that the format shown in the original email message below
isn’t original. Some space characters are deleted. I will write it in
another form:
Party A:
A-1) initial notification to a Subscribe message was without body (because
no information about the subscribed party was available)
A-2) publication of a dialog state with PUBLISH:
<dialog-info xmlns=[..] version="4" state="full" entity[..]>
A-3) publication of a dialog state with PUBLISH:
<dialog-info xmlns=[..] version="5" state="full" entity[..]>
A-4) second notification to a dialog state change (confirmed, PUBLISHed
with PUBLISH ad B-4 below):
<dialog-info xmlns=[..] version="1" ll" entity[..]>
Party B:
B-1) Initial notification to a Subscribe message:
<dialog-info xmlns=[..] version="00000000000" state="full"
entity[..]>
B-2) second notification to a dialog state change (confirmed, PUBLISHed
with PUBLISH ad A-2 above):
<dialog-info xmlns=[..] version="1" state="full"
entity[..]>
B-3) third notification to a dialog state change (terminated, PUBLISHed
with PUBLISH ad A-3 above):
<dialog-info xmlns=[..] version="2" state="full"
entity[..]>
B-4) publication of a dialog state with PUBLISH:
<dialog-info xmlns=[..] version="4" state="full" entity[..]>
So here you can (should) see that the full string-length of the
placeholder is used all time and in the situations above filled with space
characters.
Regards,
Klaus

http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users Hello list,
I have a special situation in which string characters of the
"root-line" of the notify-body are overwritten by Kamailio. In detail:
the root-line of the NOTIFY message sent to the subscriber looks like:
<dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info"
version="1"
ll" entity="sip:117090@10.16.10.99"> instead of
<dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info"
version="1"
state="full" entity="sip:117090@10.16.10.99"> In other words:
the
string state="full" is overwritten by space characters.
Is it by space
or by the versios="1"? Maybe the email body encoding ate
the spaces, above looks like one space before 'll"'.
Cheers,
Daniel
Therefore the message
is no longer "valid" and the parser of the subscriber-user agent has
problems....
The exact scenario in my use case is, that user agents can subscribe
the events "presence" and "dialog" on Kamailio. The information
about
presence and dialog-states is published to Kamailio by PUBLISH
messages from the user agents themselves. Kamailio does not have to
generate this information itself. In the following lines I have an
excerpt of the signalisation: 1) initial subscription of party A, 2)
the responded notification (without body) 3) subscription of party B
4) the responded notification (with body) 5) a publish message of the
subscribed party B with actual dialog information and 6) the
notification with body to the subscriber A.

Debug information of Kamailio and information in the source code show
that the version number "00000000000" is a placeholder only, which
should be replaced with a valid version number. However, it seems that
there is a problem in handling these strings. The version number is
replaced, but in case that the version id is only one character long,
ten space characters are inserted- overwriting other information......
Can anybody comment this problem? Is this a bug of the
presence_dialoginfo- or another module?
Thanks in advance!
Regards,
Klaus
P.S. additional information from source code an debug output of
kamailio:
notify_body.c:
[...]
/* The version must be increased for each new document and is a 32bit
int.
As the version is different for each watcher, we can not set here
the
correct value. Thus, we just put here a placeholder which will be
replaced by the correct value in the aux_body_processing callback.
Thus we have CPU intensive XML aggregation only once and can use quick
search&replace in the per-watcher aux_body_processing callback. We use
11 chracters as an signed int (although RFC says unsigned int we use
signed int as presence module stores "version" in DB as
signed int) has max. 10 characters + 1 character for the sign

New subject: SIP NOTIFY problem in 'presence_dialoginfo' module?
Hello,
yes - that is true. We have changed from using the integrated pua_x
modules to publishing the information about presence and dialog_state
information by our user agents (this was recommended by Klaus, too).
The body is built by our user agents and parts of that body are
overwritten by the presence_* modul(s). E.g. the version number in the
notify messages is never identical to the version numbers of our publish
requests including the corresponding information.
However, in the meantime we have built a crazy "workaround": our version
number now ALWAYS consists of 11 digits. E.g. version '4' is inserted into
the XML body with string '00000000004'. So the length of the placeholder
is used by our user agents, too. The result of this is: no overwriting of
the 'state="fulll"' part....
But this can only be a temporary solution. Because we are always depending
on the lovely "placeholder". Whenever this will change, we have to change
the workaround, too.......

Hello,
you said that the publish is created by the phones in your case, not by
kamailio with pua_dialoginfo, right?
If yes, then one question for Klaus D. in this case ... the body is
build in pua_dialoginfo with the placeholder and presence_dialoginfo
expects that? I had not dug in the code yet, just double-checking here.
Thanks,
Daniel

Hello Daniel,
The problem is, that the format shown in the original email message
below isnt original. Some space characters are deleted. I will write
it in another form:
Party A:
A-1) initial notification to a Subscribe message was without body
(because no information about the subscribed party was available)
A-2) publication of a dialog state with PUBLISH:
<dialog-info xmlns=[..] version="4" state="full" entity[..]>
A-3) publication of a dialog state with PUBLISH:
<dialog-info xmlns=[..] version="5" state="full" entity[..]>
A-4) second notification to a dialog state change (confirmed,
PUBLISHed
with PUBLISH ad B-4 below):
<dialog-info xmlns=[..] version="1" ll" entity[..]>
Party B:
B-1) Initial notification to a Subscribe message:
<dialog-info xmlns=[..] version="00000000000" state="full"
entity[..]>
B-2) second notification to a dialog state change (confirmed,
PUBLISHed
with PUBLISH ad A-2 above):
<dialog-info xmlns=[..] version="1" state="full"
entity[..]>
B-3) third notification to a dialog state change (terminated,
PUBLISHed
with PUBLISH ad A-3 above):
<dialog-info xmlns=[..] version="2" state="full"
entity[..]>
B-4) publication of a dialog state with PUBLISH:
<dialog-info xmlns=[..] version="4" state="full" entity[..]>
So here you can (should) see that the full string-length of the
placeholder is used all time and in the situations above filled with
space characters.
Regards,
Klaus

http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users Hello list,
I have a special situation in which string characters of the
"root-line" of the notify-body are overwritten by Kamailio. In
detail: the root-line of the NOTIFY message sent to the subscriber
looks like: <dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info"
version="1" ll" entity="sip:117090@10.16.10.99"> instead
of
<dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info"
version="1"
state="full" entity="sip:117090@10.16.10.99"> In other words:
the
string state="full" is overwritten by space characters.
Is it by space
or by the versios="1"? Maybe the email body encoding
ate the spaces, above looks like one space before 'll"'.
Cheers,
Daniel
Therefore the message
is no longer "valid" and the parser of the subscriber-user agent has
problems....
The exact scenario in my use case is, that user agents can subscribe
the events "presence" and "dialog" on Kamailio. The information
about presence and dialog-states is published to Kamailio by PUBLISH
messages from the user agents themselves. Kamailio does not have to
generate this information itself. In the following lines I have an
excerpt of the signalisation: 1) initial subscription of party A, 2)
the responded notification (without body) 3) subscription of party B
4) the responded notification (with body) 5) a publish message of
the subscribed party B with actual dialog information and 6) the
notification with body to the subscriber A.

Debug information of Kamailio and information in the source code
show that the version number "00000000000" is a placeholder only,
which should be replaced with a valid version number. However, it
seems that there is a problem in handling these strings. The version
number is replaced, but in case that the version id is only one
character long, ten space characters are inserted- overwriting other
information......
Can anybody comment this problem? Is this a bug of the
presence_dialoginfo- or another module?
Thanks in advance!
Regards,
Klaus
P.S. additional information from source code an debug output of
kamailio:
notify_body.c:
[...]
/* The version must be increased for each new document and is a
32bit int.
As the version is different for each watcher, we can not set here
the
correct value. Thus, we just put here a placeholder which will be
replaced by the correct value in the aux_body_processing
callback.
Thus we have CPU intensive XML aggregation only once and can use
quick search&replace in the per-watcher aux_body_processing
callback. We use 11 chracters as an signed int (although RFC says
unsigned int we use signed int as presence module stores "version"
in DB as
signed int) has max. 10 characters + 1 character for the sign
*/

New subject: SIP NOTIFY problem in 'presence_dialoginfo' module?
Daniel-Constantin Mierla wrote:
Hello,
you said that the publish is created by the phones in your case, not by
kamailio with pua_dialoginfo, right?
If yes, then one question for Klaus D. in this case ... the body is
build in pua_dialoginfo with the placeholder and presence_dialoginfo
expects that? I had not dug in the code yet, just double-checking here.
Sorry, I can not remember why I have choosen this approach, and
currently I have not time to dig into the code.
