This also doesn't work, see below and the wiki page says the index should be on the avpname... Can you explain what the index on the avpname does and
what the index on the subfield does, because i thought i understood, but it doesn't seem to work.
What i want to accomplish is to set an xavp (test) multiple times with multiple subfields (a & b) so that when i do an pv_unset($xavp(test)) i get the
next set of subfields (to be used for a serial forking scenario later on). This already works. Now i want to have random access to the xavp, using an
index to get to the right set of subfields. ie if i query $xavp(test[0]=>a) i get 2A, $xavp(test[1]=>b) should give 1B.
If i get this working i'll post an interesting patch to sqlops soon :)
I did some more testing and think there is a off-by-one bug somewhere:
$xavp(test=>a) = "1A";
$xavp(test[0]=>b) = "1B";
$xavp(test=>a) = "2A";
$xavp(test[0]=>b) = "2B";
$xavp(test[1]=>a) = "3A";
$xavp(test[1]=>b) = "3B";
xlog("Index on subavp");
xlog("0: $xavp(test)");
xlog("0a: $xavp(test=>a[0])");
xlog("0b: $xavp(test=>b[0])");
xlog("1: $xavp(test)");
xlog("1a: $xavp(test=>a[1])");
xlog("1b: $xavp(test=>b[1])");
xlog("2: $xavp(test)");
xlog("2a: $xavp(test=>a[2])");
xlog("2b: $xavp(test=>b[2])");
xlog("Index on avpname");
xlog("0: $xavp(test[0])");
xlog("0a: $xavp(test[0]=>a)");
xlog("0b: $xavp(test[0]=>b)");
xlog("1: $xavp(test[1])");
xlog("1a: $xavp(test[1]=>a)");
xlog("1b: $xavp(test[1]=>b)");
xlog("2: $xavp(test[2])");
xlog("2a: $xavp(test[2]=>a)");
xlog("2b: $xavp(test[2]=>b)");
Results in:

Notice that the index on the subfield doesn't return the proper values, but that the index on the avpname now returns 1A, 1B, 2A & 2B (still missing 3
thugh).
If i remove the setting of test[1]:
$xavp(test=>a) = "1A";
$xavp(test[0]=>b) = "1B";
$xavp(test=>a) = "2A";
$xavp(test[0]=>b) = "2B";
I get
