2008-01-03Cleanup #includes of standard system headers and put them in one placeEric Wong1-12/+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. Applied the following patches: * maxpath_str for reentrancy (temporary fix, reverted) * path: start working on thread-safe variants of these methods * Re-entrancy work on path/character-set conversions * directory.c: exploreDirectory() use reentrant functions here * directory/update: more use of reentrant functions + cleanups * string_toupper: a strdup-less version of strDupToUpper * get_song_url: a static-variable-free version of getSongUrl() * Use reentrant/thread-safe get_song_url everywhere * replace rmp2amp with the reentrant version, rmp2amp_r * Get rid of the non-reentrant/non-thread-safe rpp2app, too. * buffer2array: assert strdup() returns a usable value in unit tests * replace utf8ToFsCharset and fsCharsetToUtf8 with thread-safe variants * fix storing playlists w/o absolute paths * parent_path(), a reentrant version of parentPath() * parentPath => parent_path for reentrancy and thread-safety * allow "make test" to automatically run embedded unit tests * remove convStrDup() and maxpath_str() * use MPD_PATH_MAX everywhere instead of MAXPATHLEN * path: get rid of appendSlash, pfx_path and just use pfx_dir * get_song_url: fix the ability to play songs in the top-level music_directory git-svn-id: https://svn.musicpd.org/mpd/trunk@7106 09075e82-0dd4-0310-85a5-a0d7c8717e4f

2007-09-06Once again get rid of busy waiting and use SIGSTOP for pauseEric Wong1-0/+14
The problems I had were related to the OSS driver and USB device I was using. The problems existed even with the old busy-waiting scheme enabled. OSS - Bithead USB => bad ALSA - Bithead USB => OK OSS - Onboard i8x0 => OK ALSA - Onboard i8x0 => OK bad - slow shutdown, pauses, dropped audio after pause/resume git-svn-id: https://svn.musicpd.org/mpd/trunk@6861 09075e82-0dd4-0310-85a5-a0d7c8717e4f

Until we can fix it properly (or replace it with a cleaner event system), I don't want this in trunk.

2007-08-27removing debug messages from signal handlersJ. Alexander Treuman1-0/+4
As unfortunate as it is to remove such useful debugging messages, it's necessary to fix a potential deadlock with signal handling. A bunch of functions the debug functions call aren't safe to call from a signal handler. There are some alternate solutions, but they're neither pretty nor simple. So just remove them entirely for now. git-svn-id: https://svn.musicpd.org/mpd/trunk@6828 09075e82-0dd4-0310-85a5-a0d7c8717e4f
2007-08-27send SIGSTOP to player and decoder processes on pause, tooEric Wong1-0/+3
as with the stop command, this will cause the player and decoder to suspend and not wake up hundreds of times a second to poll a variable for wakeup. This will reduce power consumption on some CPUs while mpd is paused and not playing. tests: pause && unpause => OK pause && stop && play => OK pause && exit && restart w/statefile && unpause => OK pause && block sound device && \ unpause => failed to open sound device \ => still paused and suspended => unblock sound device && unpause => OK (playing) In all cases, the player process releases the audio device when paused before going into the suspended state. git-svn-id: https://svn.musicpd.org/mpd/trunk@6822 09075e82-0dd4-0310-85a5-a0d7c8717e4f

2007-06-01Tell the player process (and thus also the decode process) to quit whenJ. Alexander Treuman1-0/+23
playback is stopped completely. This means the player process will no longer have to wake up 100 times per second to see if it's been told to start playing (the main process will just spawn a new player process when it needs to). On the downside, this means an extra pair of forks() and the re-initializing of the player and decode processes each time playback is restarted. git-svn-id: https://svn.musicpd.org/mpd/trunk@6446 09075e82-0dd4-0310-85a5-a0d7c8717e4f

2007-01-14Don't initialize globals to zero (or NULL)Eric Wong1-3/+3
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 Wong1-4/+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

2006-08-14Several bugfixes during exit found by valgrindEric Wong1-1/+1
First, make sure we call finishPlaylist() before closeMp3Directory() since the latter will free non-SONG_TYPE_URL songs in playlist, which causes an invalid read when we try to look for SONG_TYPE_URL songs to free in finishPlaylist. Secondly, make sure our children have all exited before freeing the playerData. If we do not, slowly-delivered signals can trigger a race condition in the signal handlers of the decode and player processes which rely on getPlayerData. To avoid waitpid-ing too long (or at all), move the freePlayerData() call farther down in main() (this won't affect anything else) to give the OS a better chance to deliver signals and finish running sig handlers for terminated children. git-svn-id: https://svn.musicpd.org/mpd/trunk@4640 09075e82-0dd4-0310-85a5-a0d7c8717e4f

2006-07-30remove clumsy strncpy useEric Wong1-6/+4
strncpy isn't really safe because it doesn't guarantee null termination, and we have had to work around it in several places. strlcpy (from OpenBSD) isn't great, either because it often leaves errors going unchecked (by truncating strings). So we'll add the pathcpy_trunc() function with is basically strlcpy with a hardcoded MAXPATHLEN as the limit, and we'll acknowledge truncation since we only work on paths and MAXPATHLEN should be set correctly by the system headers[1]. file-specific notes: inputStream_http: eyeballing the changes here, it seems to look alright but I haven't actually tested it myself. ls: don't even bother printing a file if the filename is too long (and when is it ever?) since we won't be able to read it anyways. metadataChunk: it's only metadata, and it's only for showin the user, so truncating it here souldn't be a big issue. memset to zero in init is unecessary, so lets not waste cycles [1] - If the system headers are screwed up, then we're majorly screwed regardless of what we do :x git-svn-id: https://svn.musicpd.org/mpd/trunk@4491 09075e82-0dd4-0310-85a5-a0d7c8717e4f

2006-07-30interface/connection malloc reductions from mpd-keEric Wong1-13/+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
