( https://gerrit.osmocom.org/c/osmocom-bb/+/33329 ) Change subject: layer23: fix handling of logging category mask (-d option) ...................................................................... layer23: fix handling of logging category mask (-d option) In change 67943df4 I broke handling of the logging category mask in the mobile app. Adding this option results in a segfault: ERROR: osmo_log_info == NULL! You must call log_init() before using logging in log_parse_category_mask()! Assert failed osmo_log_info src/libosmocore/src/core/logging.c:329 As can be seen, the problem is that we are calling log_parse_category_mask() before initializing the logging. As possible solution, I could rearrange the code to parse command line options after calling osmo_init_logging2(). This would fix the segfault, but would not fully solve the problem. If we call log_parse_category_mask() before parsing the config file, then logging configuration in the config file overwrites the logging configuration specified via the command line. But we want the opposite: the command line setting should overwrite the config file parameters. This is handy because there is no need to edit the config file if you quickly need to test something. So let's call log_parse_category_mask() after parsing the config file.
