A new Flyspray task has been opened. Details are below.
User who did this - Juha Heinanen (jh)
Attached to Project - sip-router Summary - tls module 'config' param can point to directory Task Type - Improvement Category - tls Status - Assigned Assigned To - Andrei Pelinescu-Onciul Operating System - All Severity - Medium Priority - Normal Reported Version - Development Due in Version - Undecided Due Date - Undecided Details - i modified tls/tls_config.c tls_load_config() function so that it checks if file pointed to by 'config' module param is a directory. if it is, tls_load_config() copies all regular files of that directory to a tmp file and then passes that tmp file to cfg_parser. that way config parser can stay as is.
reason for this improvement is that it is easier from management point of view to add/remove files when peers come and go rather than edit a monolithic single config file. modified tls_load_config() is below. feel free to implement same functionality in some other way. i don't care how it is done as long as the feature is available. if adopted, i'll update README accordingly.
