git:master: domain: Add internal function is_domain_local

Module: sip-router Branch: master Commit: d8fdebf9c589516185d5c6a4ff9453148f1b76f2 URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=d8fdebf… Author: Jan Janak <jan(a)iptel.org> Committer: Jan Janak <jan(a)iptel.org> Date: Fri Jul 17 11:10:51 2009 +0200 domain: Add internal function is_domain_local Add internal function is_domain_local that can be used to determine if the domain name given in parameter is on the list of local domains. The comparison of the domain name is always case insensitive. There already is is_local function that does something similar, so we can reuse the code from that function. is_domain_local takes a pointer to str as parameter and this function is then called by is_local which takes all the usual parameters that function which can be called from the script take. Finally, is_domain_local is exported through the internal API of the domain module. Function is_domain_local is now located in file domain.c and because of db_get_did was also moved to file domain.c --- modules_s/domain/domain.c | 104 +++++++++++++++++++++++++++++++++++++++++ modules_s/domain/domain.h | 17 +++++++ modules_s/domain/domain_api.c | 1 + modules_s/domain/domain_api.h | 3 +- modules_s/domain/domain_mod.c | 91 +----------------------------------- 5 files changed, 126 insertions(+), 90 deletions(-) diff --git a/modules_s/domain/domain.c b/modules_s/domain/domain.c index cd347bf..cb5cb32 100644 --- a/modules_s/domain/domain.c +++ b/modules_s/domain/domain.c @@ -22,6 +22,7 @@ #include <string.h> #include "domain_mod.h" +#include "hash.h" #include "../../dprint.h" #include "../../mem/shm_mem.h" #include "../../lib/srdb2/db.h" @@ -308,3 +309,106 @@ int load_domains(domain_t** dest) free_domain_list(list); return 1; } + + +/* Retrieve did directly from database, without using memory cache.

[ openser-Bugs-2822344 ] Branch route has wrong ruri or missing headers

by SourceForge.net

Bugs item #2822344, was opened at 2009-07-16 11:06 Message generated for change (Tracker Item Submitted) made by axlh You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=743020&aid=2822344&group_… Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: None Group: ver 1.4.x Status: Open Resolution: None Priority: 5 Private: No Submitted By: Alex Hermann (axlh) Assigned to: Nobody/Anonymous (nobody) Summary: Branch route has wrong ruri or missing headers Initial Comment: The scenario: In branch route, I rewrite the ruri and add an additional header. When the destination fails and DNS-based failover takes place, the branch route is called again. For this second branch, the ruri is not the same as the ruri at t_relay time. Also the extra header is missing. So this bug could be either: - The ruri and rest of variables/packet for each branch should be the same as the ruri at t_relay time or - The header added in the first branch route should also be present for the second branch (in the case of DNS-based failover) I would either expect the ruri and all other variables and headers to be exactly the same as at t_relay time for each branch, or (for DNS-based failover ONLY) the packet sent to a failover destination to be exactly the same as the first branch (including any added headers / from replacement, etc.) Not a mix of both. Before t_relay: $rU = "*1234567890" t_relay("0x03"); my branch route: xlog("L_NOTICE", "Branch: <$ru> via <$du>\n"); if (is_method("INVITE") and $(rU{s.substr,0,3}) == "*12") { strip(3); append_hf("X-Test: 12\r\n"); } The log: Jul 15 09:14:38 Branch: <sip:*1234567890@test.domain;transport=udp> via <<null>> Jul 15 09:14:38 Reply Status: 503 Service Unavailable Jul 15 09:14:38 Branch: <sip:234567890@test.domain;transport=udp> via <<null>> Jul 15 09:14:38 Reply Status: 100 Trying ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=743020&aid=2822344&group_…
