Mike BradyandGitHub cbbfe83f3b Update RELEASENOTES.md 2019-02-19 11:18:13 +00:00
Mike BradyandGitHub 78685b8528 Big update to audio_jack.c and other stuff 2019-02-19 11:13:17 +00:00
Mike BradyandGitHub ec84f0fd98 Merge pull request #809 from nettings/development 
Modify audio_jack.c to use native jack lockless buffers and to offer auto connect facilities. Overall, the backend is now written more in the idiom of jack audio.

Many thanks to [Jörn Nettingsmeier](https://github.com/nettings).

Jörn Nettingsmeier 5c1769f87c Partly revert c00199d664, some 0 are actually longs. It's late :( 2019-02-16 02:28:59 +00:00
Jörn Nettingsmeier 3a4deb38a2 Declare all file-global variables as static, remove unused thread pointer. 2019-02-16 02:26:36 +00:00
Jörn Nettingsmeier 90f24c62df Add myself to (C)omplain-to tag :-D 2019-02-16 02:20:21 +00:00
Jörn Nettingsmeier c00199d664 Always use NULL instead of 0 for pointers for clarity. 2019-02-16 02:15:35 +00:00
Jörn Nettingsmeier 95246dcd84 Use more conservative JACK client name (a simple token without whitespace). 2019-02-16 02:05:05 +00:00
Jörn Nettingsmeier 4751a4e1bc Move jack base latency computation out of delay() into graph() to save cycles. 2019-02-16 02:03:15 +00:00
Jörn Nettingsmeier bda8b99cda Add graph reorder callback, this is where we now compute the output latencies. 2019-02-16 01:53:49 +00:00
Jörn Nettingsmeier f1ba07ff2b Make callback names simpler and more consistent. Always use &callback in setter functions to make the function pointer explicit, even though it's not syntactically necessary. 2019-02-16 01:02:30 +00:00
Jörn Nettingsmeier 0009fcddf6 Revert "Remove client_mutex, since JACK opening and closing is now single-threaded." 
That was a bit too optimistic, I guess. Must understand more about the rest of shairport-sync.
Fixes spurious segfault on program termination with CTRL-C that does not happen in gdb :)
This reverts commit 8e46c727d5.
 2019-02-16 00:53:04 +00:00
Jörn Nettingsmeier 55797c8387 Remove unused headers. <getopt.h> will come back once we implement command line parsing, the others may well be gone for good. 2019-02-15 23:51:11 +00:00
Jörn Nettingsmeier 8e46c727d5 Remove client_mutex, since JACK opening and closing is now single-threaded. 2019-02-15 23:45:12 +00:00
Jörn Nettingsmeier 2826756938 Remove global client_is_open flag, always execute former conditional statements. We know we're open. 2019-02-15 23:43:00 +00:00
Jörn Nettingsmeier 753cc07777 Remove optional is_running() API call, since it doesn't do anything useful. 
We are either already running along just fine, or we are throughly dead.
 2019-02-15 23:39:53 +00:00
Jörn Nettingsmeier 1906bfd727 Remove indirections open_if_needed() and close(), can now be integrated into API calls init and deinit. 2019-02-15 23:38:01 +00:00
Jörn Nettingsmeier ec68c677e0 Remove jack_stop() function pointer from API struct, since it does nothing. Checked, no segfault on program termination. 2019-02-15 23:17:50 +00:00
Jörn Nettingsmeier 8c5e85c87c Remove audio_client_disconnect option. This is not good behaviour for a JACK client, and adds nothing. 2019-02-15 23:14:31 +00:00
Jörn Nettingsmeier edd699dfbc Remove auto_client_open_interval option, always open JACK connection immediately or fail. 
Remove client creation thread and wrapper function.
 2019-02-15 23:08:04 +00:00
Jörn Nettingsmeier 63b3381a27 Fail early and fail deadly (AFAIK there is no fallback to another audio backend, so any severe JACK issue should be fatal). 2019-02-15 22:59:31 +00:00
