Using htable module while developing other modules

by Mojtaba

Hello, According to previous my question about udsing htable module as dependencies module in other modules (Actually i mean hiops module), i want to have some changes in my code. Already i saved some data in cache memory that is implemented via linked_list structure in module, i want to replace them with htable module. So i have to load htable module and some more extra works, all things are straightforward. But when i have more dived into htable module (api.c, ht_api.c files), there is no function to get the value of specific key. there is "ht_api_get_cell_expire_f" function that it just get back the expire time, no value of key. Now I need a function that it return the value of key also, Could i add this function in api.c and ht_api.c source files and commit it or not? If there is already the function like this, let me know about it? Let me know about it? With Regards -- --Mojtaba Esfandiari.S

[kamailio] dialog module with broken defaults (#372)

by zabbal

If I enable dialog module Kamailio will fail to start with following error: ERROR: dialog [dialog.c:498]: mod_init(): no dlg flag set!! In the documentation this parameter is set to 4 as an example: modparam("dialog", "dlg_flag", 4) But no comments made as to why number 4 is used, which numbers are possible to use and most importantly - why such default value is chosen? In any case - module should use default which does not break server's configuration. --- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/372
