2008-09-29Switch to C99 types (retaining compat with old compilers)Eric Wong1-2/+2
Seeing the "mpd_" prefix _everywhere_ is mind-numbing as the mind needs to retrain itself to skip over the first 4 tokens of a type to get to its meaning. So avoid having extra characters on my terminal to make it easier to follow code at 2:30 am in the morning. Please report any new issues you may come across on Free toolchains. I realize how difficult it can be to build/maintain cross-compiling toolchains and I have no intention of forcing people to upgrade their toolchains to build mpd. Tested with gcc 2.95.4 and and gcc 4.3.1 on x86-32.
2008-09-02tag: renamed functions, no CamelCaseMax Kellermann1-2/+2
2008-09-02tag: renamed MpdTag and MpdTagItem to struct mpd_tag, struct tag_itemMax Kellermann1-2/+2
Getting rid of CamelCase; not having typedefs also allows us to forward-declare the structures.
2008-08-30aac: support decoding AAC streamsMax Kellermann1-2/+128
Copy some code from aac_decode() to aac_stream_decode() and apply necessary changes to allow streaming audio data. Both functions might be merged later.
2008-08-30aac: splitted aac_parse_header() from initAacBuffer()Max Kellermann1-11/+16
initAacBuffer() should really only initialize the buffer; currently, it also reads data from the input stream and parses the header. All of the AAC buffer code should probably be moved to a separate library anyway.
2008-08-30aac: check buffer lengthsMax Kellermann1-2/+3
The AAC plugin sometimes does not check the length of available data when checking for magic prefixes. Add length checks.
2008-08-30aac: use fillAacBuffer() instead of manual readingMax Kellermann1-16/+4
Eliminate some duplicated code by using fillAacBuffer().
2008-08-30find AAC framesMax Kellermann1-1/+35
Find AAC frames in the input and skip invalid data. This prepares AAC streaming.
2008-08-30aac: moved code to adts_check_frame()Max Kellermann1-11/+20
adts_check_frame() checks whether the buffer head is an AAC frame, and returns the frame length.
2008-08-30aac: moved code to aac_buffer_shift()Max Kellermann1-7/+14
Shifting from the buffer queue is a common operation, and should be provided as a separate function. Move code to aac_buffer_shift() and add a bunch of assertions.
2008-08-30aac: use inputStreamAtEOF()Max Kellermann1-5/+4
When checking for EOF, we should not check whether the read request has been fully satisified. The InputStream API does not guarantee that readFromInputStream() always fills the whole buffer, if EOF is not reached. Since there is the function inputStreamAtEOF() dedicated for this purpose, we should use it for EOF checking after readFromInputStream()==0.
2008-08-30aac: don't depend on consumed data in fillAacBuffer()Max Kellermann1-6/+10
Fill the AacBuffer even when nothing has been consumed yet. The function should not check for consumed data, but for free space at the end of the buffer.
2008-08-30aac: simplified fillAacBuffer()Max Kellermann1-33/+25
Return instead of putting all the code into a if-closure. That saves one level of indentation.
2008-08-30aac: make adtsParse() voidMax Kellermann1-3/+1
adtsParse() always returns 1, and its caller does not use the return value.
2008-08-30aac: use size_tMax Kellermann1-6/+6
2008-08-30aac: removed unused initAacBuffer() parametersMax Kellermann1-9/+3
Since we eliminated the parameters retFileread and retTagsize in all callers, we can now safely remove it from the function prototype.
2008-08-30eliminate unused variables in the AAC decoderMax Kellermann1-10/+2
2008-08-30aac/mp4: removed local variable "eof" because it is unusedMax Kellermann1-7/+5
"break" is so much easier than "eof=1; continue;", when "!eof" is the loop condition.
2008-08-30clean up CPP includesMax Kellermann1-4/+0
Include only headers which are really required. This speeds up compilation and helps detect cross-layer accesses. [ew: minor fixups to not break on new core]
2008-08-16core rewrite (decode,player,outputBuffer,playlist)Eric Wong1-30/+14
This is a huge refactoring of the core mpd process. The queueing/buffering mechanism is heavily reworked. The player.c code has been merged into outputBuffer (the actual ring buffering logic is handled by ringbuf.c); and decode.c actually handles decoding stuff. The end result is several hundreds of lines shorter, even though we still have a lot of DEBUG statements left in there for tracing and a lot of assertions, too.
2008-04-13Make the OutputBuffer API more consistentEric Wong1-3/+3
We had functions names varied between outputBufferFoo, fooOutputBuffer, and output_buffer_foo That was too confusing for my little brain to handle. And the global variable was somehow named 'cb' instead of the more obvious 'ob'... git-svn-id: https://svn.musicpd.org/mpd/trunk@7355 09075e82-0dd4-0310-85a5-a0d7c8717e4f
2008-04-13Stop passing our single OutputBuffer object everywhereEric Wong1-4/+4
All of our main singleton data structures are implicitly shared, so there's no reason to keep passing them around and around in the stack and making our internal API harder to deal with. git-svn-id: https://svn.musicpd.org/mpd/trunk@7354 09075e82-0dd4-0310-85a5-a0d7c8717e4f
2008-04-13Stop passing our single DecoderControl object everywhereEric Wong1-17/+17
This at least makes the argument list to a lot of our plugin functions shorter and removes a good amount of line nois^W^Wcode, hopefully making things easier to read and follow. git-svn-id: https://svn.musicpd.org/mpd/trunk@7353 09075e82-0dd4-0310-85a5-a0d7c8717e4f

2008-04-12Initial cut of fork() => pthreads() for decoder and playerEric Wong1-0/+2
I initially started to do a heavy rewrite that changed the way processes communicated, but that was too much to do at once. So this change only focuses on replacing the player and decode processes with threads and using condition variables instead of polling in loops; so the changeset itself is quiet small. * The shared output buffer variables will still need locking to guard against race conditions. So in this effect, we're probably just as buggy as before. The reduced context-switching overhead of using threads instead of processes may even make bugs show up more or less often... * Basic functionality appears to be working for playing local (and NFS) audio, including: play, pause, stop, seek, previous, next, and main playlist editing * I haven't tested HTTP streams yet, they should work. * I've only tested ALSA and Icecast. ALSA works fine, Icecast metadata seems to get screwy at times and breaks song advancement in the playlist at times. * state file loading works, too (after some last-minute hacks with non-blocking wakeup functions) * The non-blocking (*_nb) variants of the task management functions are probably overused. They're more lenient and easier to use because much of our code is still based on our previous polling-based system. * It currently segfaults on exit. I haven't paid much attention to the exit/signal-handling routines other than ensuring it compiles. At least the state file seems to work. We don't do any cleanups of the threads on exit, yet. * Update is still done in a child process and not in a thread. To do this in a thread, we'll need to ensure it does proper locking and communication with the main thread; but should require less memory in the end because we'll be updating the database "in-place" rather than updating a copy and then bulk-loading when done. * We're more sensitive to bugs in 3rd party libraries now. My plan is to eventually use a master process which forks() and restarts the child when it dies: locking and communication with the main thread; but should require less memory in the end because we'll be updating the database "in-place" rather than updating a copy and then bulk-loading when done. * We're more sensitive to bugs in 3rd party libraries now. My plan is to eventually use a master process which forks() and restarts the child when it dies: master - just does waitpid() + fork() in a loop \- main thread \- decoder thread \- player thread At the beginning of every song, the main thread will set a dirty flag and update the state file. This way, if we encounter a song that triggers a segfault killing the main thread, the master will start the replacement main on the next song. * The main thread still wakes up every second on select() to check for signals; which affects power management.

2008-01-03Cleanup #includes of standard system headers and put them in one placeEric Wong1-4/+1
This will make refactoring features easier, especially now that pthreads support and larger refactorings are on the horizon. Hopefully, this will make porting to other platforms (even non-UNIX-like ones for masochists) easier, too. os_compat.h will house all the #includes for system headers considered to be the "core" of MPD. Headers for optional features will be left to individual source files. git-svn-id: https://svn.musicpd.org/mpd/trunk@7130 09075e82-0dd4-0310-85a5-a0d7c8717e4f
2008-01-01Simplify decode cleanup logic a bitEric Wong1-8/+0
DECODE_STATE_STOP is always set as dc->state, and dc->stop is always cleared. So handle it in decodeStart once rather than doing it in every plugin. While we're at it, fix a long-standing (but difficult to trigger) bug in mpc_decode where we failed to return if mpc_decoder_initialize() fails. git-svn-id: https://svn.musicpd.org/mpd/trunk@7122 09075e82-0dd4-0310-85a5-a0d7c8717e4f

2007-01-14Don't initialize globals to zero (or NULL)Eric Wong1-12/+1
Some compilers and linkers aren't smart enough to optimize this, as global variables are implictly initialized to zero. As a result, binaries are a bit smaller as more goes in the .bss and less in the text section. git-svn-id: https://svn.musicpd.org/mpd/trunk@5254 09075e82-0dd4-0310-85a5-a0d7c8717e4f

2006-08-26Replace strdup and {c,re,m}alloc with x* variants to check for OOM errorsEric Wong1-1/+1
I'm checking for zero-size allocations and assert()-ing them, so we can more easily get backtraces and debug problems, but we'll also allow -DNDEBUG people to live on the edge if they wish. We do not rely on errno when checking for OOM errors because some implementations of malloc do not set it, and malloc is commonly overridden by userspace wrappers. I've spent some time looking through the source and didn't find any obvious places where we would explicitly allocate 0 bytes, so we shouldn't trip any of those assertions. We also avoid allocating zero bytes because C libraries don't handle this consistently (some return NULL, some not); and it's dangerous either way. git-svn-id: https://svn.musicpd.org/mpd/trunk@4690 09075e82-0dd4-0310-85a5-a0d7c8717e4f
