* core: Add infrastructure for synchronizing HW and SW volume changesJyri Sarha2010-10-161-1/+6
| | | | | | | | | | | | | | | | To make concurrent use of SW and HW volume glitchles their application needs to be synchronized. For accurate synchronization the HW volume needs to be applied in IO thread. This patch adds infrastructure to delay the applying of HW volume to match with SW volume timing. To avoid synchronization problems this patch moves many of the volume and mute related functions from main thread to IO thread. All these changes become active only if the sync volume flag for a sink has been set. So, for this patch to have any effect it needs to be taken into use by sink implementor.

* volume: Decrease PA_VOLUME_MAX to be < 2^31Arun Raghavan2010-10-151-1/+1
| | | | | | | This decrease PA_VOLUME_MAX to be less than 2^31. We want to do this in order to simplify signed arithmetic when applying software volume scaling (since the volume can now always be safely treated as a signed number).
* volume: Clamp volume to PA_VOLUME_MAXArun Raghavan2010-10-152-9/+14
| | | | | | This ensures that we always clamp the volume to PA_VOLUME_MAX. While this currently has no effect, it will be required for making sure we don't exceed PA_VOLUME_MAX when its value changes in the future.
* volume: Use a macro to check if a volume is validArun Raghavan2010-10-153-19/+22
| | | | | | | This adds a PA_VOLUME_IS_VALID() macro for checking if a given pa_volume_t is valid. This makes changes to the volume ranges simpler (just change PA_VOLUME_MAX, for example, without needing to modify any other code).
* doxygen: Add 'See also' linking to the overview pageDavid Fries2010-10-1312-11/+46
| | | | | | | A good many of the header files are broken into a function reference page and an overview page. These changes add a direct link from each function reference page to their overview page if one exists.
* doxygen: Documentation improvementsDavid Fries2010-10-135-15/+16
| | | | | | | | | stream.h, simple.h The words drain and flush are a little ambiguous, make it explicit as to what happens to any existing audio. *mainloop.h reword *_free and *_get_api for grammar
* doxygen: Fix the "all" comments regarding volume helper functions.David Fries2010-10-131-10/+11
| | | | | | Mostly change "Set the volume of all channels" to "Set the volume of the first n channels" as the first is incorrect, it doesn't set all the channels and doesn't explain what n was for.

| | | | | This commit restores the functionality originally included in 65e807 by Leszek Koltunski.

* x11: Partially convert to XCB.Colin Guthrie2010-09-181-12/+11
| | | | | | | | | This commit mostly converts the X11 handling to XCB. There are still some uses of XLib to deal with the X11 session handling modules, however all client-side code should now be free of XLib and thus this should fix Bug #799 Note that this removes the screen-based changes by Leszek Koltunski in 65e80, however this will be restored in due course.

* channelmap: Use "Subwoofer" as pretty name for LFELennart Poettering2010-02-211-1/+1
| | | | | | The pretty name is suspposed to be understandable by non-technical folks, and they are generally more used to the term "Subwoofer" than "Low Frequency Emitter", so let's change the name here.
* native: rework handling of seeks that depend on variables the client does ↵Lennart Poettering2010-02-091-0/+5
| | | | | | | | | | | | not know anything about All seeks/flushes that depend on the playback buffer read pointer cannot be accounted for properly in the client since it does not know the actual read pointer. Due to that the clients do not account for it at all. We need do the same on the server side. And we did, but a little bit too extreme. While we properly have not applied the changes to the "request" counter we still do have to apply it to the "missing" counter. This patch fixes that.

| | | | | | | This allows easy overriding of a clients latency setting for debugging purposes. http://pulseaudio.org/ticket/753
* client: verify connection state in pa_stream_connect_upload()Lennart Poettering2010-02-091-0/+1
| | | | | | | Make suer we check the connection state before going on, so that we can rely that s->context->pstream is properly initialized. https://bugzilla.redhat.com/show_bug.cgi?id=539500

* native: fix request counter miscalculationsLennart Poettering2010-02-091-0/+4
| | | | | | | | | | | | | Do not subtract bytes the client sends us beyond what we requested from our missing bytes counter. This was mostly a thinko that caused servers asking for too little data when the client initially sent more data than requested, because that data sent too much was accounted for twice. This commit fixes this miscalculation. http://bugzilla.redhat.com/show_bug.cgi?id=534130
* dbus: remove filter functions only if they were actually set beforeLennart Poettering2010-02-092-19/+7

| | | | | | | | | This is the same typo as reported in [1] and fixed in [2] in `client.conf.in`. I did `git grep "values a commented"` and did not get anymore hits. [1] http://pulseaudio.org/ticket/783 [2] http://git.0pointer.de/?p=pulseaudio.git;a=commit;h=ea8927f1d47be101a1f64b2f87fd6e527ff76dbe

| * poll() is totally broken on Mac OS XDaniel Mack2009-12-161-7/+2
| | | | | | | | | | | | Even on 10.5.8, poll() does not do the right thing. Haven't checked on newer versions. Hence, wrap all occurences of poll() to pa_poll and emulate that call with select() on OSX. This is totally embarassing.
* | headers: Some trivial fixes for some documentation typosMads Kiilerich2010-01-056-10/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Note also the willneed/will_need inconsistency. I guess it could be nice to ASAP choose one of them and introduce a backward compatibility hack for the other. The issues was mostly found with: for a in $(grep -r '^[ /]\*.*()' $( find -name '*.[ch]') | sed 's,^.* \([^ ]*\)().*$,\1,g' | sort | uniq | grep ^pa_) do grep -rq "^.[^*].*\<$a(" $(find * -name '*.h') || echo $a done
* | threaded-mainloop: Properly initialise m->n_waiting_for_accept to prevent ↵Daniel T Chen2010-01-051-0/+1
|/ | | | | | | | | | | | | deadlock Compiler optimisations have been seen to initialise m->n_waiting_for_accept to a positive non-zero value, so the while() in pa_threaded_mainloop_signal() never proceeds. Fix this by properly initializing m->n_waiting_for_accept in pa_threaded_mainloop_new(). Patch from Iain Bucław. https://bugs.launchpad.net/bugs/502992
* Mark shared variables as volatileArun Raghavan2009-12-061-1/+4
| | | | | | | | | 'n_waiting' and 'n_waiting_for_accept' may be accessed from mulitple threads, and thus need to be marked as volatile to suppres certain compiler optimisations. All uses are protected by a mutex, so we don't need to worry about cache issues (added documentation for this as well). This addresses bug #738.
* libpulse: Store pa_stream pointers to hashmaps instead of dynarrays.Tanu Kaskinen2009-12-033-18/+17
| | | | | | | | | Since the stream identifiers (channels) are monotonically growing integer, it isn't a good idea to use them as index to a dynamic array, because the array will grow all the time. This is not a problem with client connections that don't create many streams, but, for example, long-running clients that use libcanberra for playing event sounds, this means that the client connection effectively leaks memory.

| * device-manager: Change the write function to a rename function.Colin Guthrie2009-10-012-40/+16
| | | | | | | | | | | | | | The structure itself will contain various bits of info so exposing this fully to the client is a bad idea. By keeping to a rename operation we keep what we do store abstracted from the clients. Also fix some doxy comments.
