Hi Jamey,
I am interested for testing the new extensions of the pa module from the
latest
unstable release. However, I got problem for configuring pa module.
This is the stacktrace I got from the coredump when I was trying to load
the pa module:
> (gdb) bt
> #0 0x4207a453 in strlen () from /lib/tls/libc.so.6
> #1 0x4009725d in pa_mod_init () at pa_mod.c:148
> #2 0x08070387 in init_mod (m=0x80d4328) at sr_module.c:453
> #3 0x08070411 in init_modules () at sr_module.c:476
> #4 0x0805a629 in main (argc=1, argv=0xbfffd9e4) at main.c:1425
> #5 0x42015574 in __libc_start_main () from /lib/tls/libc.so.6
> (gdb)
I think it was coming from this line of code in pa_mod.c:
> db_url.len = strlen(db_url.s);
Since I didn't set the parameter 'db_url' for pa module in ser.cfg, I got
the segmentation fault as shown above. If I set the parameter to some
value, then the fault is gone.
However, I don't know how to create the db for pa, I still can not get it
running
correctly.
It will be appreciated if you can provide me some instructions or examples
for
creating the db as well as setting the new parameters (presentity_table,
watcherinfo_table) and using the new commands.
Best Regards,
Kevin

I will check in a fix to prevent this segv.

I will add a pa.sql script for creating the tables.

The db_url is the same form as that of the usrloc db, e.g., mysql.
Here are the pa params I'm using now:
# -- pa params --
modparam("pa", "use_db", 1)
modparam("pa", "db_url", "mysql://ser:heslo@localhost/ser")
There is currently a problem that pa does not pick up basic presence
from ser itself, because it needs that info on a per contact basis,
which means some changes to usrloc. I attempted that, but did not get
it working. Right now pa is depending on the UA or presence UA
PUBLISH'ing that info using application/cpim-pidf+xml format.
Here are routing rules for PUBLISH and SUBSCRIBE:
if (method=="PUBLISH") {
if (!t_newtran()) {
log(1, "newtran error\n");
sl_reply_error();
};
handle_publish("registrar");
log(1,"handled publish\n");
break;
};
if (method=="SUBSCRIBE") {
if (!t_newtran()) {
log(1, "newtran error\n");
sl_reply_error();
};
log(1, "handling subscription\n");
handle_subscription("registrar");
log(1,"handled subscribe\n");
break;
};
Another problem is that Windows Messenger does not like the notifies
that pa is sending. If anyone has any ideas what is wrong I would like
to know about it.
I'm deploying this version of the PA at the Internet2 Joint Techs
Meeting in Hawaii next week as part of an Internet2 Presence Integrated
Communication working group demo.
