* fix output buffer deadlock when daemonizingEric Wong2008-08-191-1/+0
| | | | | | | | | | | We spawned the output buffer thread before daemonizing in initPlayerData(), which is ultra bad because daemonizes forks and threads are not preserved on exit. Since playerData has been stripped bare by this core-rewrite anyways, move this code into the outputBuffer_* group and drop playerData.[ch] completely I completely forgot to test this :<

* clean up CPP includesMax Kellermann2008-04-121-4/+3
| | | | | | | | | Try to only include headers which are really needed. We should particularly check all "headers including other headers". The long-term goal is to have a manageable, small API for plugins (decoders, output) without so many mpd internals cluttering the namespace. git-svn-id: https://svn.musicpd.org/mpd/trunk@7319 09075e82-0dd4-0310-85a5-a0d7c8717e4f

* audio: use a machine word for array sizesMax Kellermann2008-03-261-17/+17
| | | | | | | | we do not save anything by limiting a variable to an unsigned char, since the compiler aligns it at machine word size anyway. however by using the full machine word, we save one instruction, and we remove the useless artificial limitation to 255. git-svn-id: https://svn.musicpd.org/mpd/trunk@7203 09075e82-0dd4-0310-85a5-a0d7c8717e4f
* explicitly downcastMax Kellermann2008-03-261-4/+4

* Cleanup #includes of standard system headers and put them in one placeEric Wong2008-01-031-9/+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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | thread-safety work in preparation for rewrite to use pthreads Expect no regressions against trunk (r7078), possibly minor performance improvements in update (due to fewer heap allocations), but increased stack usage.

* Replace strdup and {c,re,m}alloc with x* variants to check for OOM errorsEric Wong2006-08-261-3/+3
| | | | | | | | | | | | | | | | | | | 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

* interface/connection malloc reductions from mpd-keEric Wong2006-07-301-9/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch massively reduces the amount of heap allocations at the interface/command layer. Most commands with minimal output should not allocate memory from the heap at all. Things like repeatedly polling status, currentsong, and volume changes should be faster as a result, and more importantly, not a source of memory fragmentation. These changes should be safe in that there's no way for a remote-client to corrupt memory or otherwise do bad stuff to MPD, but an extra set of eyes to review would be good. Of course there's never any warranty :) No longer do we use FILE * structures in the interface, which means we don't have to allocate any new memory for most connections. Now, before you go on about losing the buffering that FILE * +implies+, remember that myfprintf() never took advantage of any of the stdio buffering features. To reduce the diff and make bugs easier to spot in the diff, I've kept myfprintf in places where we write to files (and not network interfaces). Expect myfprintf to go away entirely soon (we'll use fprintf for writing regular files). git-svn-id: https://svn.musicpd.org/mpd/trunk@4483 09075e82-0dd4-0310-85a5-a0d7c8717e4f
