Hello Daniel,

you could
access it by adding some sht extensions to the Perl API, same
way as for AVP, but this requires development as well.
From other modules is easier, as one can evaluate the name and then do
search in the hashtable.
unfortunately you cannot use $sht in this way
from perl module. The
same limitation that prevent calling any function from modules apply
here -- the fixup system used at startup, when string parameters are
pre-compiled in different forms to speed up runtime execution.
So there is no way
to access $sht from other moduls (like perl or
xlog)? It seems to work, but obviously the memory isn't freed :-)
What we are trying to do is the following:
During processing of "INVITE" we need to save some call details
(source IP, URI, ...) and want to write them to file when the call is
finished (including duration, ...), while processing BYE or CANCEL, to
have CDRs. As there are multiple childs of kamailio we tried to save
the calls details from the INVITE in shared memory using htable (e.g.
"$sht(a=>$ci::srcip) = $si"), so we can use them while processing the
BYE (possibly in another child). There we wanted to use perl to be
able to write the saved details to a file.
We used the shared memory module as we don´t want to save the infos to
DB because of performance issues we suspect when using DBs.
But as you mentioned $sht is not supposed to be used in such a way. Do
you have any idea what else we can do to generate CDRs as mentioned?
By using other modules for example or a complete other way you may know?
You can use shared memory from perl, see persistence.pl in
modules/perl/doc/samples/
Cheers,
Daniel
It can be added as a feature request for future. For module functions
I added the core support for free fixup functions, but nobody
committed to continue the work in perl module.
If you want to work on it, I can assist and guide you.
Well, honestly we are
looking for a fast way to implement it.
How long will it take to implement it with your guidance?
Thanks and regards,
Christian
