As previously discussed on the mailing list, this is a bug. I have a fix that works, so I'll provide a pull request.

### Description

I’m trying to use function xavp_rm_by_index to remove a specific index from a given xavp. I’m observing an unexpected behaviour, I think it might be a bug. Instead of just removing the index, the function removes the index and all others before it.

E.g : if called with « idx = 1 », it removes indexes 0 and 1.

Reading the code of xavp_rm_internal (which is called by xavp_rm_by_index), I don’t think it behaves at it should :

``` /* Remove xavps * idx: <0 remove all xavps with the same name * >=0 remove only the specified index xavp * Returns number of xavps that were deleted */ ```

For example when I do this :

``` LM_ERR("COUNT BEFORE: %d\n", xavp_count(rname, NULL)); int rm_count = xavp_rm_by_index(rname, 1, NULL); // TEST LM_ERR("REMOVED: %d\n", rm_count); LM_ERR("COUNT AFTER: %d\n", xavp_count(rname, NULL)); ```

« rm_count » returned is 1 (which is expected). However, « count after » is decremented by 2. And when I look at the contents of my xavp, I notice that the first two elements have been removed.

Likewise if xavp_rm_by_index is invoked with idx = 2 => the first 3 elements are removed.

### Troubleshooting

#### Reproduction

Here is some code that shows the issue :

1) a test cmd_function in a module defined as follows :

``` static int was_test(struct sip_msg *msg, char *param1, char *param2);

static cmd_export_t cmds[] = { {"was_test", (cmd_function)was_test, 2, 0, 0, ANY_ROUTE}, {0, 0, 0, 0, 0, 0} };

/** * For testing purposes. */ static int was_test(struct sip_msg *msg, char *param1, char *param2) { LM_WARN("Called with param1: [%s], param2: [%s]\n", param1, param2);

str my_str; my_str.s = param1; my_str.len = strlen(param1);

int idx = atoi(param2); str *rname = &my_str;

LM_ERR("COUNT BEFORE: %d\n", xavp_count(rname, NULL));

int rm_count = xavp_rm_by_index(rname, idx, NULL);

LM_ERR("REMOVED: %d\n", rm_count); LM_ERR("COUNT AFTER: %d\n", xavp_count(rname, NULL));

return 1; } ```

2) Kamailio script :

``` request_route {

# push 4 rows to xavp "test": $xavp(test=>a) = "3.a"; $xavp(test[0]=>b) = "3.b";

$xavp(test=>a) = "2.a"; $xavp(test[0]=>b) = "2.b";

$xavp(test=>a) = "1.a"; $xavp(test[0]=>b) = "1.b";

$xavp(test=>a) = "0.a"; $xavp(test[0]=>b) = "0.b";

# then try to call xavp_rm_by_index with a non-zero idx xlog("L_INFO", "BEFORE\n"); xlog("L_INFO", "test[*]: [$(was_xavp_serialize(test)[*])]\n"); pv_xavp_print();

was_test("test", "1"); // expecting only row 1 to be removed (1.a / 1.b)

xlog("L_INFO", "AFTER\n"); xlog("L_INFO", "test[*]: [$(was_xavp_serialize(test)[*])]\n"); pv_xavp_print();

} ```
