How to let kamailio to ignore siptrace db errors
by Mino Haluz 26 Mar '12

26 Mar '12

Hi, please, I would like to adjust the siptrace module so that it will carry on processing the calls when the siptrace module is unable to insert the trace into database. As the machine where the siptrace is being stored is sometimes undergoing high load , kamailio stops responding because siptrace cannot insert the record into db. Instead of, it could just write an error/notice or something .. Thanks. Mino.

TLS certificates and database
by Torrey Searle 22 Mar '12

Hello, Does anybody know if it is technically feasible to make Kamailio's TLS module source TLS certificates from a database instead of a directory? Or would such functionality not be allowed by the OpenSSL library? Thanks! Torrey

DB replace
by Daniel-Constantin Mierla 21 Mar '12

21 Mar '12

Hello, looking at previous commits and the utility of a "replace" SQL command, I think it can be implemented in kamailio for those modules providing "affected_rows" but no native "replace". Pretty much like done for postgres case inside rls/pua, but done within a mutex lock, to avoid any kind of race. For proper concurrency, I think there should be an array of mutexes (gen_lock_set_t) , the exact mutex to be used will be selected based on a hash value over the unique key values of the record. That means the "replace" DB API method should be extended with two new parameters to specify the unique key values, a db_val_t array (kvals) and its number of elements (kn): typedef int (*db_replace_f) (const db1_con_t* handle, const db_key_t* keys, const db_val_t* vals, const int n, const db_val_t* kvals, const int kn); In the case the unique key values are at the beginning of the vals array, then vals can be reused for kvals and kn set accordingly. When the kvals array is null, no mutex will be used. Of course, if db library has native "replace" function, that will be used and the last two parameters will be ignored. In short, to implement replace() for postgres: - DB API replace method will be extended with two parameters - db_postgres will allocate at startup an array of mutex locks (AS) - its size (LS) to be set by module parameter - postgres replace() will compute the hash as: H = get_hash1_raw(kvals[0]) + ... + get_hash1_raw(kvals[kn-1]) -- if kval[N] is not string, but integer, its value can be used directly instead of getting to string and then hashing it - the mutex to be used will be M = AS[H % LS] - the rest of replace() as pseudocode: lock(M) do DB UPDATE if affected rows==0 do DB INSERT unlock(M) or, as the chance to have insert succeed in most of the cases can be relevant in some cases, the order can be: lock(M) do DB INSERT if insert error do DB UPDATE unlock(M) The way to be done can be a third new param to replace method -- this implementation does not require "affected rows", eventually to detect based on error code that it was a duplicate key failure. Then some other modules can use replace() mechanism easier (e.g, as discussed on IRC devel meeting, usrloc can solve inconsistency when db was not available for some time) -- such usage (insert or replace) can be a matter of module parameters, if wanted, from case to case. Any other opinions? I am not a postgres user, but I can try to make a patch if there are testers and nobody else wants to take over.
