Otherwise, the ll command handler parses the argument and calls daemon_set_loglevel(). The lopsub stanza for the subcommand is stored in a separate file which is currently only included by the lopsub suite for para_audiod, but will be included as well by the server suite. For similar reasons we implement the completer as a generic public function, i9e_ll_completer(), although it only has one caller in audioc.c. Another caller follows when the ll server command is added. 2022-07-02T19:29:07Z Andre Noll maan@tuebingen.mpg.de 2021-10-19T19:28:30Z urn:sha1:a0cd2ac59b891751067512dce77cf6223104932f Currently the severity string (debug, info, etc.) given to --loglevel is parsed twice: Once by lopsub, which returns the loglevel as the index into the array of severity strings. We turn this index into a string and pass the string to daemon_set_loglevel() which parses the string again to turn it back into a log level value (which happens to coincide with the index value). Clean this up by letting daemon_set_loglevel() receive a log level value rather than a severity string. This also allows us to remove the now unused ENUM_STRING_VAL() macro from audiod.c. 2018-03-13T02:28:10Z Andre Noll maan@tuebingen.mpg.de 2017-08-07T22:02:03Z urn:sha1:ced0c17d1a3ee0336dc7b35e69faff131dabecac Currently the server processes append messages to the log file without coordination. This usually does not cause problems, but sometimes the log messages of the main server process and the afs process get interleaved due to the lack of serialization. This patch serializes access to the common log file by employing a new lock: the log_mutex. Like the mmd_mutex, it is realized as an one-element System V semaphore set. Logging is performed by the daemon subsystem implemented in daemon.c. This subsystem is also used by para_audiod which is single-threaded and thus does not need to care about serialization of log messages. To keep daemon.c working for both para_server and para_audiod, struct daemon gains two optional methods, ->pre_log_hook and ->post_log_hook. If the function pointers are not NULL, the methods are called before and after a message is logged. For para_server the methods call back to the server code to take and release the lock. para_audiod does not need to be modified because if the new function pointers are left at their default value NULL, so no hooks are called. 2016-10-04T10:19:48Z Andre Noll maan@tuebingen.mpg.de 2016-06-16T18:17:21Z urn:sha1:7d28108f4691e0e7df199fd89f386cafeb3466c7 If parent_waits is true, the parent process waits for a signal from the child before it exits. However, this signal can arive before the parent has set up its signal handler. This patch closes the race window by switching from signals to pipes. We now create a pipe before the new process is forked, and let the parent block on read(2) until the child exits or indicates success by writing a byte to one end of the pipe. The child process receives the file descriptor of the writing end of the pipe as the return value of daemonize(). The only user of the parent_waits feature is para_server, which is changed accordingly. 2016-08-07T12:03:44Z Andre Noll maan@tuebingen.mpg.de 2016-06-21T07:19:57Z urn:sha1:cf47da359caca907d8f0fd8fe9f5f4ddb398b67d The function receives the values given to the --log-color option as a char * array, which is the type that gengetopt provides for the arguments to string options which may be given multiple times. This patch gets get rid of this implementation detail. The function no longer takes the arguments to --log-color at all and applications now must call daemon_set_log_color_or_die() themselves to set user-defined per-loglevel colors. To make this work, we let daemon_init_colors_or_die() return a boolean which indicates whether color mode should be enabled, and daemon_set_log_color_or_die() is made public. The two users of this API, para_server and para_audiod, are adjusted accordingly. 2016-07-03T13:57:16Z Andre Noll maan@tuebingen.mpg.de 2016-06-21T21:27:54Z urn:sha1:92d85d340495154f3fda23f322af13fc9de42155 daemon_set_logfile() and daemon_set_loglevel() do not modify the passed string, so the type of the argument should be const char *. 2015-10-15T21:10:57Z Andre Noll maan@tuebingen.mpg.de 2015-10-08T16:25:06Z urn:sha1:bbd70648da0f4168df34c1f1651d67af089e7be6 On slow hardware it is useful to set the priority of the para_audiod process to avoid sound artefacts due to buffer underruns. This patch adds an option for this purpose which is available for para_server and para_audiod. 2015-02-08T14:58:14Z Andre Noll maan@tuebingen.mpg.de 2014-10-07T16:16:14Z urn:sha1:3943f98061a55f373991ecb2e4429ec02baf0555 The log color logic is already contained in para_server and para_audiod. Let's use a single function in daemon.c for this purpose. daemon_set_default_log_colors() and daemon_set_log_color_or_die() can be made static since they are only called from daemon.c now. 2015-01-12T22:29:07Z Andre Noll maan@tuebingen.mpg.de 2015-01-01T18:15:21Z urn:sha1:448cb0a00f29a7f0655e318e018b0d802fab95e9 Found by cppcheck.
