* Simplify decode cleanup logic a bitEric Wong2008-01-011-26/+15
| | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* decode: fix seek when pausedEric Wong2007-09-071-0/+1
| | | | | | We need to SIGCONT the decoder process to allow for seeking while paused. git-svn-id: https://svn.musicpd.org/mpd/trunk@6864 09075e82-0dd4-0310-85a5-a0d7c8717e4f
* Once again get rid of busy waiting and use SIGSTOP for pauseEric Wong2007-09-061-4/+10
| | | | | | | | | | | | | | 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
* return to busy-waiting on pause for now..Eric Wong2007-09-061-10/+4
| | | | | | | | Until we can fix it properly (or replace it with a cleaner event system), I don't want this in trunk. Currently there are strange pauses when queueing and during shutdown that I can't seem to figure out right away. git-svn-id: https://svn.musicpd.org/mpd/trunk@6860 09075e82-0dd4-0310-85a5-a0d7c8717e4f
* removing debug messages from signal handlersJ. Alexander Treuman2007-08-271-3/+5
| | | | | | | | | 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
* send SIGSTOP to player and decoder processes on pause, tooEric Wong2007-08-271-4/+10
| | | | | | | | | | | | | | | | | | | | | | | | 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
* decode: close audio device after initial open if pausedJ. Alexander Treuman2007-08-121-1/+5
| | | | | | | | | | Currently, if we start decoding while the pause flag is set, we open the audio device and leave it opened, blocking other apps from using it. The obvious thing to do is to not open the audio device if the pause flag is set, but the open call also sets the audio format. Therefore I'm leaving the open call in, and just closing it immediately afterwards if the pause flag is set. git-svn-id: https://svn.musicpd.org/mpd/trunk@6745 09075e82-0dd4-0310-85a5-a0d7c8717e4f

* decode: prefer fileDecodeFunc over streamDecodeFunc for filesJ. Alexander Treuman2007-06-251-9/+10
| | | | | | | | | Only wavpack implements both fileDecodeFunc and streamDecodeFunc, and it's fileDecodeFunc provides more functionality. So try using that first. This commit also fixes a bug where the plugin test loop wouldn't break once a suitable plugin was found if it used fileDecodeFunc. git-svn-id: https://svn.musicpd.org/mpd/trunk@6655 09075e82-0dd4-0310-85a5-a0d7c8717e4f

Since it's a local variable and can't be modified externally, it'll never be hit. git-svn-id: https://svn.musicpd.org/mpd/trunk@6524 09075e82-0dd4-0310-85a5-a0d7c8717e4f

* Don't initialize globals to zero (or NULL)Eric Wong2007-01-141-1/+1
| | | | | | | | Some compilers and linkers aren't smart enough to optimize this, as global variables are implictly initialized to zero.

* Do not set metadataState to PLAYER_METADATA_STATE_READ when decoding stops.J. Alexander Treuman2006-12-241-1/+0
| | | | | | | | This fixes a bug where streams that won't play somehow appear with the metadata of a previously played stream. As far as I can tell, the only reason this is done is to sync any buffered metadata with the displayed metadata when decoding stops, so there should be no other adverse effects. git-svn-id: https://svn.musicpd.org/mpd/trunk@5161 09075e82-0dd4-0310-85a5-a0d7c8717e4f

* Replace strdup and {c,re,m}alloc with x* variants to check for OOM errorsEric Wong2006-08-261-2/+2
| | | | | | | | | | | | | | | | | | | 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

* Revert leaks from r4311, and also the leak fixes as a result of thatEric Wong2006-08-141-7/+3
| | | | | | | | | | | | | | | | | | | | | | utf8ToFsCharset() and fsCharsetToUtf8() got very broken in r4311, and resulted in several commits to fix those leaks. Unfortunately, not all of those newly introduced leaks were fixed, nor was the result pretty. Also, fixed a double-free in lsPlaylists(). This is very hard to trigger (and therefore exploit) at the moment because we check printDirectoryInfo() beforehand. Intended behavior for utf8ToFsCharset() and fsCharsetToUtf8() as God^H^H^Hshank originally intended is now documented in path.h to prevent future errors like this. mpd could still use some good valgrind testing before the 0.12.0 release. <plug>In addition to reducing heap fragmentation, malloc reductions from mpd-ke greatly reduces the chance of leaks from happening due to programming errors.</plug> git-svn-id: https://svn.musicpd.org/mpd/trunk@4639 09075e82-0dd4-0310-85a5-a0d7c8717e4f

* remove clumsy strncpy useEric Wong2006-07-301-18/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
