* PcmResampleLibsamplerate: clip 24 bit dataMax Kellermann2013-11-223-2/+47
| | | | | | Using pcm_resample_lsr_32() for 24 bit samples works, but may cause 24 bit overflows. This commit makes 24 bit a special case with explicit clipping.
* PcmResample: un-inline Resample24()Max Kellermann2013-11-222-7/+13

* PcmUtils: add function PcmClampN()Max Kellermann2013-11-221-0/+12

|
* DatabasePlugin: add method GetUpdateStamp()Max Kellermann2013-11-226-26/+26
| | | | | | Refactor SimpleDatabase::GetLastModified() to be generic for all plugins. Remove the SimpleDatabase assumption from db_stats_print(), allowing it to be implemented by all database plugins.
* Stats: print db statistics only if db is availableMax Kellermann2013-11-221-6/+19
| | | | Fixes crash on "stats" in certain configurations.

* Stats: don't export the global variable "stats"Max Kellermann2013-11-222-3/+1
| | | | Unused outside of Stats.cxx.

|
* Mapper: _get_music_directory_utf8() may return nullptrMax Kellermann2013-11-222-2/+5
| | | | | | If no music_directory is configured, return nullptr instead of an empty string. This fixes a crash when db_file is configured without music_directory.
* system/ByteOrder: testing for endianness in a more general wayFlorian Schlichting2013-11-211-1/+11

* PlayerThread: fix stuck MPD after song change (0.18.2 regression)Max Kellermann2013-11-081-4/+8
| | | | | | | | | | | | | Commit 77c63511 caused MPD to become stuck right after a song change. The problem was that at some point, the MusicBuffer became full, and the DecoderThread working on the next song waits for the PlayerThread. However, the PlayerThread was stuck in a loop of g_usleep() calls, and never bothered to tell the DecoderThread that the MusicBuffer is not full anymore. This bug is very old, but its chance to occur went from nearly 0% to nearly 100%. The fix is to wake up the DecoderThread before waiting for it. As a side effect, I replaced the g_usleep() call with a Cond::Wait() call.
* DecoderInternal: simplify need_chunks()Max Kellermann2013-11-081-11/+4
| | | | | Remove the "do_wait" parameter which is always true. Check only command==NONE and merge the "return" statements.
* DecoderInternal: don't wake up player in need_chunksMax Kellermann2013-11-081-1/+0
| | | | Nothing of interest happens here. No need to wake up the player.
* input/cdio_paranoia: add setting "default_byte_order"Max Kellermann2013-11-071-2/+26
| | | | | | Allows big-endian users to configure the fallback byte order to little-endian. Without this setting, MPD assumes native byte order if the CD drive can't decide.
* AvahiPoll: don't close the dbus socketMax Kellermann2013-11-071-0/+4
| | | | Avoid closing it twice.
* input/curl: unregister removed sockets from epollMax Kellermann2013-11-071-1/+9
| | | | Fixes a crash bug. See code comment.
* OutputControl: reduce the number of OutputThread wakeupsMax Kellermann2013-11-064-2/+30
| | | | | Wake up the OutputThread only if it hasn't already been woken up and if it isn't already in the playback loop.
* PlayerThread: reduce the number of DecoderThread wakeupsMax Kellermann2013-11-061-2/+14
| | | | | | | After the number of decoded chunks has fallen below the threshold, the PlayerThread woke up the DecoderThread over and over. This commit adds a boolean flag that avoids these duplicate wakeups, and thus reduces the number of system calls.
* DecoderControl: reduce the number of PlayerThread wakeupsMax Kellermann2013-11-063-4/+26
| | | | | Wake up the PlayerThread only if it is really waiting for the decoder. This greatly reduces the number of system calls in the DecoderThread.
* DecoderInternal: lock DecoderControl in _flush_chunk()Max Kellermann2013-11-062-0/+4
| | | | Must hold the Mutex to signal the Cond object safely.
* DecoderInternal: wake up the player thread in _flush_chunk()Max Kellermann2013-11-062-4/+2
| | | | Merge duplicate code.
* event/FullyBufferedSocket: remove obsolete TODO commentMax Kellermann2013-11-061-16/+0
| | | | We have a better solution now.
* ClientRead: "close" flushes the output bufferMax Kellermann2013-11-063-1/+12
| | | | | | Add a new CommandResult code called "FINISH" which, unlike "CLOSE", will attempt to flush the output buffer. This is a one-shot attempt; it will do one write, and not try again.
* event/FullyBufferedSocket: try to write without extra roundtripMax Kellermann2013-11-062-17/+33
| | | | | | Postpone the write using IdleMonitor instead of scheduling a write event. This reduces the number of system calls, because we don't need to register and unregister the write event in epoll.
* event/FullyBufferedSocket: make WriteFromBuffer() protectedMax Kellermann2013-11-062-4/+4
| | | | .. and rename it to Flush().
* PlayerThread: enable buffering when starting playbackMax Kellermann2013-11-061-1/+1
| | | | | | For some reason, this got lost in commit 975deca8. Re-enabling this fixes stuttering at the beginning of radio streams.
* input/curl: fix bug with redirected streamsMax Kellermann2013-11-061-110/+138
| | | | | | | | | | | Migrate from the old curl_multi_perform() API to the newer curl_multi_socket_action() API (since CURL 7.16). This allows working around a bug with HTTP redirections with epoll: when CURL closes a socket and the new one happens to have the same file number, MPD did not have a chance to remove the old one from epoll and subsequently attempted to use EPOLL_CTL_MOD, which was not allowed by epoll, because it's a new socket now.
* input/curl: move code into class CurlMultiMax Kellermann2013-11-061-43/+66
| | | | | Move all global variables there, and keep just one global variable: the pointer to the CurlMulti instance. Prepares for the next commit.
* input/curl: remove the global list of requestsMax Kellermann2013-11-061-13/+0
| | | | Unused.
* input/curl: don't abort all requests on curl_multi_perform() errorMax Kellermann2013-11-061-40/+7
| | | | Eliminate some complicated code that's not worth the trouble.
* input/curl: use CURLOPT_PRIVATEMax Kellermann2013-11-061-5/+7
| | | | Replaces the loop in input_curl_find_request().
* event/SocketMonitor: add method Abandon()Max Kellermann2013-11-064-2/+32
|
* system/ByteOrder: fix big-endian supportMax Kellermann2013-11-051-2/+2
| | | | D'oh!
