* playlist: don't allow no-op/senseless movement of songsEric Wong2008-01-261-8/+14
| | | | | | | | | | This disables moving the bonkered moving of the current song to a (negative) offset of itself (introduced in the last commit). This also short circuits no-op moves when (from == to) and avoid needless increasing of the playlist version and causes clients to issue pointless no-op plchanges commands. git-svn-id: https://svn.musicpd.org/mpd/trunk@7153 09075e82-0dd4-0310-85a5-a0d7c8717e4f
* playlist: allow move to specify offset from current songEric Wong2008-01-261-1/+10
| | | | | | | | | | | | | | | | If (and only if) there is a current song in the playlist, (player could be stopped), allow the move destination argument to be specified as a negative number. This means moving any song (besides the current one) to the -1 position will allow it to be moved to the next song in the playlist. Moving any song to position -2 will move it to the song after the next, and so forth. Moving a song to -playlist.length will move it to the song _before_ the current song on the playlist; so this will work for repeating playlists, too. git-svn-id: https://svn.musicpd.org/mpd/trunk@7152 09075e82-0dd4-0310-85a5-a0d7c8717e4f
* addToPlaylist/addSongToPlaylist: printId argument changed to added_idEric Wong2008-01-261-8/+9
| | | | | | | | | | | | Instead of printing out the Id from playlist.c, instead set the integer that added_id poitns to if added_id is non-NULL. This makes the API cleaner and will allow us to use additional commands to manipulate the newly-added song_id. Callers (handleAddId) that relied on printId to print it to the given fd have now been modified to print the ID at a higher-level; making playlist.c less-dependent on protocol details. git-svn-id: https://svn.musicpd.org/mpd/trunk@7149 09075e82-0dd4-0310-85a5-a0d7c8717e4f

* Cleanup #includes of standard system headers and put them in one placeEric Wong2008-01-031-8/+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
* storedPlaylist: remove the needless StoredPlaylist struct and just use ListEric Wong2008-01-011-8/+8
| | | | | | | | | | | Abstractions should reduce the amount of code and make things easier to follow. The StoredPlaylist struct did not do that, so get rid of it and just use our standard linked list implementation instead. diffstat agrees with me that the abstraction is pointless: 3 files changed, 60 insertions(+), 90 deletions(-) git-svn-id: https://svn.musicpd.org/mpd/trunk@7120 09075e82-0dd4-0310-85a5-a0d7c8717e4f

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).

* Replace strdup and {c,re,m}alloc with x* variants to check for OOM errorsEric Wong2006-08-261-11/+11
| | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | 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

* interface/connection malloc reductions from mpd-keEric Wong2006-07-301-122/+127
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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
