Hi, Mickael!
Can you check if there are also any transactions hanged? Also, What is
the scenario you are using? When are you populating these variables?

Hi Razvan,
I have some news.
The suspects are not regular AVPs but branch AVPs that I set in a module.
Is there a specific handling for those AVPs?
Here is how I use it:
static str bavp_msgops_flags = str_init("$bavp(_msgops_bflags)");
pv_spec_t bavp_msgops_flags_spec;
In mod_init:
if (parse_store_bavp(&bavp_msgops_flags, &bavp_msgops_flags_spec)) {
LM_ERR("Fail to parse branch AVPs.\n");
return -1;
}
In a command called from branch_route:
b_flags.flags = PV_VAL_INT|PV_TYPE_INT;
b_flags.ri = 0;
if(pv_set_value(msg, &bavp_msgops_flags_spec, (int)EQ_T, &b_flags) != 0) {
LM_ERR("Fail to set branch flags AVP.\n");
return -1;
}
Sometimes, I do the following to get the branch AVP value:
if (pv_get_spec_value(rpl, &bavp_msgops_flags_spec, &b_flags_val) != 0) {
LM_ERR("Branch AVP not found!\n");
return;
}
Thanks,
Mickael

Not sure why the signal is triggered. But what you could do is to
replicate the behavior of the function until you find the proper id.

Hi Razvan,
I'm using GDB as follows:
(gdb) p get_avp_name_id(((struct usr_avp*)0x2ba445441948)->id)
Program received signal SIGUSR2, User defined signal 2.
get_avp_name_id (id=139) at usr_avp.c:263
263 {
The program being debugged was signaled while in a function
called from GDB.
GDB remains in the frame where the signal was received.
To change this behavior use "set unwindonsignal on"
Evaluation of the expression containing the function
(get_avp_name_id) will be abandoned.
where ((struct usr_avp*)0x2ba445441948)->id gives me the AVP id.
I expect the result to be of type str* (representing the AVP
name) but it looks like some signal is received while executing
the function.
Any idea?
Thanks,

That's the correct usage, and the AVP is attached to the
transaction, and destroyed when the transaction is destroyed.
However, it depends on the context when the AVP is populated.
Is it done for each message? Timer based?
If I were you, I'd continue tracing the name of the AVPs and
checking where they are populated.

Looking for example at the DIALPLAN module, it looks like
the same procedure is followed, so I don't see anything
special I'm doing here.

Hi Razvan,
I do the following:
static str my_avp_name = {NULL, 0};
static pv_spec_t my_avp;
static param_export_t params[] = {
.....
{ "my_avp",STR_PARAM, &my_avp_name.s}
};
static int mod_init(void) {
....
my_avp_name.len = strlen(my_avp_name.s);
....
if(my_avp_name.s == NULL || my_avp_name.len == 0) {
return -1;
}
if (pv_parse_spec(&my_avp_name, &my_avp) == 0 ||
my_avp.type != PVT_AVP) {
return -1;
}
}
Then, when I want to set a value to my AVP (for example,
for setting an integer):
pv_value_t pvar_value;
pvar_value.flags = PV_VAL_INT|PV_TYPE_INT;
pvar_value.ri = some_integer;
if(pv_set_value(msg, &my_avp, (int)EQ_T, &pvar_value) < 0) {
goto error;
}
And, that's all. I don't detroy the AVP after use
because the module can't know the AVP is not used
anymore. I can destroy the AVP in the script after use
but I thought it was handled automatically.
In the example I gave here, is the AVP attached to a
transaction? What are the conditions for an AVP to be
attached to a transaction?
Thanks,
Mickael

Hi, Mickael!
Both maps are relevant, because both of them contain
id2name mappings. So you should definitely look into
the avp_map too. Note that those mappings do not
store AVPs, they only store the real name of the
AVP, as you use in script, and they can be populated
at startup (in this case they are stored in PKG) and
runtime (stored in SHM).
It depends when the AVP should be destroyed: if they
are attached to the transaction (and they usually
are), they are automatically destroyed by the tm
module. Otherwise the module that uses them, should
take care of that.

Hi Razvan,
I looked at both avp_map and avp_map_shm. In our
case, only avp_map_shm is relevant since the leak
appears in shared memory. I only see 4 elements in
this map while I can see a lot of remaining AVPs
when looking at the memory dump created at shutdown
using QM debug. Therefore, it looks like these AVPs
are not in the map. Looking at the new_avp function
in usr_avp.c, I don't see at any moment that an
entry is added to the map for the new AVP.
(gdb) print avp_map_shm->avl_count
$5 = 4
(gdb) print avp_map->avl_count
$6 = 140
Any idea?
At which moment during execution an AVP is
destroyed? Is it required for modules returning
values to script through AVPs to destroy these
AVPs? or are they automatically destroyed?
Thanks,
Mickael

This is not entirely true - you can define AVPs
with the integer value 0. Those will have
avp->flags == 0 and avp->data == 0.
What I'd do, is to note down the avp->id value
of those AVPs and then try to see their names.
To do that, you'd have to look into the avp_map
and avp_map_shm maps to see the corresponding
name for that id. Alternatively you can call in
your script the avp_print() method, which
prints all the AVPs for a specific transaction
along with their id and names. Let me know how
this goes.
