Hello,
I'm running kamailio 5.1.4 and running into a issue with htable. I use it to store some dialog data so i can use it in a http route. When i use the callid as a key it creates a issue for callid's starting with eq. Here some example code that i use to reproduce the issue:
modparam("htable", "htable", "ht_test=>size=16;autoexpire=10")
$var(htable-val) = $_s($dlg(h_entry)) + "::" + $_s($dlg(h_id)) + "::" + $Ts; xlog("L_WARN", "HT_TEST: Adding $var(htable-val) to ht_test with key eq1234"); $var(htid) = "eq1234"; $sht(ht_test=>$var(htid)) = $var(htable-val); $var(htable-val) = $null;
if ($shtcn(ht_test=>$var(htid)) > 0) { xlog("L_WARN", "HT_TEST: Key eq1234 found!"); } else { xlog("L_WARN", "HT_TEST: Key eq1234 NOT found!"); } $var(htid) = $null;
Results in :
Oct 16 09:36:31 sip03 /usr/sbin/kamailio[22344]: WARNING: <script>: HT_TEST: Adding 531::926::1539675391 to ht_test with key eq1234 Oct 16 09:36:31 sip03 /usr/sbin/kamailio[22344]: WARNING: <script>: HT_TEST: Key eq1234 NOT found!
When i prefix eq with a 1 it works fine:
modparam("htable", "htable", "ht_test=>size=16;autoexpire=10")
$var(htable-val) = $_s($dlg(h_entry)) + "::" + $_s($dlg(h_id)) + "::" + $Ts; xlog("L_WARN", "HT_TEST: Adding $var(htable-val) to ht_test with key eq1234"); $var(htid) = "1eq1234"; $sht(ht_test=>$var(htid)) = $var(htable-val); $var(htable-val) = $null;
if ($shtcn(ht_test=>$var(htid)) > 0) { xlog("L_WARN", "HT_TEST: Key eq1234 found!"); } else { xlog("L_WARN", "HT_TEST: Key eq1234 NOT found!"); } $var(htid) = $null;

Am i running into a bug? Or are there some restrictions on the key's i can use? I'm still going trough the logs to check if there are more callid's that have a issue with matching.
Thanks,

Hello,
the expression in the $shtcn(table=>exp) can have some operators at the beginning, see:
- https://www.kamailio.org/wiki/cookbooks/devel/pseudovariables#shtcn_htable_e...
So, eq is one of them, the safest is to explicitly set the operator if you cannot predict what is the key, like in this case. If the operator is missing, then the exp is matched as regular expression, so you can do:
$shtcn(ht_test=>~~$var(htid))
Cheers, Daniel
