[PATCH 3/5] sms: Do not store received id in the SMS database.

From: Alexander Chemeris &lt;alexander.chemeris(a)gmail.com&gt; That was a bad idea from the very beginning. A visible result of this is a wrong SMS routing when you change subscriber extensions, while having queued SMS. It's also a very wrong thing from the code layering perspective. I think the next logical step should be to remove "receiver" pointer from the gsm_sms structure into a structure, special for the internal SMS queue. --- openbsc/src/libmsc/db.c | 31 ++++++++++--------------------- 1 file changed, 10 insertions(+), 21 deletions(-) diff --git a/openbsc/src/libmsc/db.c b/openbsc/src/libmsc/db.c index df26b04..88bd9ad 100644 --- a/openbsc/src/libmsc/db.c +++ b/openbsc/src/libmsc/db.c @@ -95,7 +95,6 @@ static char *create_stmts[] = { "id INTEGER PRIMARY KEY AUTOINCREMENT, " "created TIMESTAMP NOT NULL, " "sent TIMESTAMP, " - "receiver_id INTEGER NOT NULL, " "deliver_attempts INTEGER NOT NULL DEFAULT 0, " /* data directly copied/derived from SMS */ "valid_until TIMESTAMP, " @@ -1233,19 +1232,19 @@ int db_sms_store(struct gsm_sms *sms) /* FIXME: correct validity period */ result = dbi_conn_queryf(conn, "INSERT INTO SMS " - "(created, receiver_id, valid_until, " + "(created, valid_until, " "reply_path_req, status_rep_req, protocol_id, " "data_coding_scheme, ud_hdr_ind, " "user_data, text, " "dest_addr, dest_ton, dest_npi, " "src_addr, src_ton, src_npi) VALUES " - "(datetime('now'), %llu, %u, " + "(datetime('now'), %u, " "%u, %u, %u, " "%u, %u, " "%s, %s, " "%s, %u, %u, " "%s, %u, %u)", - sms->receiver ? sms->receiver->id : 0, validity_timestamp, + validity_timestamp, sms->reply_path_req, sms->status_rep_req, sms->protocol_id, sms->data_coding_scheme, sms->ud_hdr_ind, q_udata, q_text, @@ -1266,7 +1265,6 @@ int db_sms_store(struct gsm_sms *sms) static struct gsm_sms *sms_from_result(struct gsm_network *net, dbi_result result) { struct gsm_sms *sms = sms_alloc(); - long long unsigned int receiver_id; const char *text, *daddr, *saddr; const unsigned char *user_data; @@ -1275,16 +1273,6 @@ static struct gsm_sms *sms_from_result(struct gsm_network *net, dbi_result resul sms->id = dbi_result_get_ulonglong(result, "id"); - receiver_id = dbi_result_get_ulonglong(result, "receiver_id"); - sms->receiver = subscr_get_by_id(net, receiver_id); - if (!sms->receiver) { - LOGP(DLSMS, LOGL_ERROR, - "Failed to find receiver(%llu) for id(%llu)\n", - receiver_id, sms->id); - sms_free(sms); - return NULL; - } - /* FIXME: validity */ /* FIXME: those should all be get_uchar, but sqlite3 is braindead */ sms->reply_path_req = dbi_result_get_uint(result, "reply_path_req"); @@ -1302,6 +1290,7 @@ static struct gsm_sms *sms_from_result(struct gsm_network *net, dbi_result resul strncpy(sms->dst.addr, daddr, sizeof(sms->dst.addr)); sms->dst.addr[sizeof(sms->dst.addr)-1] = '\0'; } + sms->receiver = subscr_get_by_extension(net, sms->dst.addr); sms->src.npi = dbi_result_get_uint(result, "src_npi"); sms->src.ton = dbi_result_get_uint(result, "src_ton"); @@ -1356,7 +1345,7 @@ struct gsm_sms *db_sms_get_unsent(struct gsm_network *net, unsigned long long mi result = dbi_conn_queryf(conn, "SELECT SMS.* " "FROM SMS JOIN Subscriber ON " - "SMS.receiver_id = Subscriber.id " + "SMS.dest_addr = Subscriber.extension " "WHERE SMS.id >= %llu AND SMS.sent IS NULL " "AND Subscriber.lac > 0 " "ORDER BY SMS.id LIMIT 1", @@ -1386,10 +1375,10 @@ struct gsm_sms *db_sms_get_unsent_by_subscr(struct gsm_network *net, result = dbi_conn_queryf(conn, "SELECT SMS.* " "FROM SMS JOIN Subscriber ON " - "SMS.receiver_id = Subscriber.id " - "WHERE SMS.receiver_id >= %llu AND SMS.sent IS NULL " + "SMS.dest_addr = Subscriber.extension " + "WHERE Subscriber.id >= %llu AND SMS.sent IS NULL " "AND Subscriber.lac > 0 AND SMS.deliver_attempts < %u " - "ORDER BY SMS.receiver_id, SMS.id LIMIT 1", + "ORDER BY Subscriber.id, SMS.id LIMIT 1", min_subscr_id, failed); if (!result) return NULL; @@ -1415,8 +1404,8 @@ struct gsm_sms *db_sms_get_unsent_for_subscr(struct gsm_subscriber *subscr) result = dbi_conn_queryf(conn, "SELECT SMS.* " "FROM SMS JOIN Subscriber ON " - "SMS.receiver_id = Subscriber.id " - "WHERE SMS.receiver_id = %llu AND SMS.sent IS NULL " + "SMS.dest_addr = Subscriber.extension " + "WHERE Subscriber.id = %llu AND SMS.sent IS NULL " "AND Subscriber.lac > 0 " "ORDER BY SMS.id LIMIT 1", subscr->id); -- 1.9.1
