* enable -Wpointer-arith, -Wstrict-prototypesMax Kellermann2008-08-261-2/+4
| | | | | | Also enable -Wunused-parameter - this forces us to add the gcc "unused" attribute to a lot of parameters (mostly library callback functions), but it's worth it during code refactorizations.

* use constant pointers when possibleMax Kellermann2008-04-121-13/+12
| | | | | | It is a good practice to constify pointers when their dereferenced data is not modified within the functions or its descendants. git-svn-id: https://svn.musicpd.org/mpd/trunk@7234 09075e82-0dd4-0310-85a5-a0d7c8717e4f
* use size_tMax Kellermann2008-03-261-1/+1
| | | | | | | | When dealing with in-memory lengths, the standard type "size_t" should be used. Missing one can be quite dangerous, because an attacker could provoke an integer under-/overflow, which may provide an attack vector. git-svn-id: https://svn.musicpd.org/mpd/trunk@7205 09075e82-0dd4-0310-85a5-a0d7c8717e4f
* Cleanup #includes of standard system headers and put them in one placeEric Wong2008-01-031-4/+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

* Make pcm_convertAudioFormat return the buffer size. This is necessaryJ. Alexander Treuman2007-05-261-17/+20
| | | | | | | | because lsr may return less than the input buffer size, and the rest of the audio code needs to know the new size. This fixes the clicking that was introduced with recent changes to the lsr code. A huge thanks to remiss for figuring this out. git-svn-id: https://svn.musicpd.org/mpd/trunk@6273 09075e82-0dd4-0310-85a5-a0d7c8717e4f
* Reverting to the full lsr API. Turns out the simple API needs all of theJ. Alexander Treuman2007-05-241-29/+52
| | | | | | | | audio at once, so it won't work for us. The old full API code was still heavily broken, as each call to pcm_convertSampleRate() used the same state, even if it was processing two streams of audio. The new code keeps a separate state for each audio stream that's being converted. git-svn-id: https://svn.musicpd.org/mpd/trunk@6255 09075e82-0dd4-0310-85a5-a0d7c8717e4f

* Switching to the lsr simple API. The problem with the full API is that theJ. Alexander Treuman2007-05-231-19/+7
| | | | | | | | | | | number of channels is specified when the converter state is created. Previously this was only done once, thus breaking horribly when the input audio suddenly had a different channel count. A new state could be created every time the number of channels changes, but this could happen many times a second if resampling to two different formats at once. The simple API doesn't have this problem, as channel count is an argument to the conversion function itself. git-svn-id: https://svn.musicpd.org/mpd/trunk@6229 09075e82-0dd4-0310-85a5-a0d7c8717e4f

* pcm_utils: fix libsamplerate compilation with non-C99 compilersEric Wong2007-02-191-4/+12
| | | | | | | | | | | | Mixing code and declarations is ugly, anyways. We could probably get away with using alloca(), but I'm not sure how good compiler support is for that, either. It's probably more supported than mixed declarations and code. Nevertheless; we'll trigger memory checkers on exit because we don't free the buffers; but we won't actually leak because we reuse those buffers (just like the non-SRC code path). git-svn-id: https://svn.musicpd.org/mpd/trunk@5397 09075e82-0dd4-0310-85a5-a0d7c8717e4f

* Don't initialize globals to zero (or NULL)Eric Wong2007-01-141-4/+4
| | | | | | | | 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
* Replace strdup and {c,re,m}alloc with x* variants to check for OOM errorsEric Wong2006-08-261-3/+4
| | | | | | | | | | | | | | | | | | | 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
