* song: converted typedef Song to struct songMax Kellermann2008-10-111-2/+2
| | | | | | | | | | | | | | | Again, a data type which can be forward-declared. [ew: * used "struct mpd_song" instead to avoid token duplication (like I did with "struct mpd_tag") as there's no good abbreviation for "song" and identical tokens on the same line don't read well * rewritten using perl -i -p -e 's/\bSong\b/struct mpd_song/g' src/*.[ch] since it was too hard to merge * also, I don't care much for forward declarations ]

* Revert "Start using song pointers in core data structures"Eric Wong2008-10-021-1/+1
| | | | | | | This actually opened us up to making lock dependencies more difficult than they needed to be now that we have threaded updates. We would always use the memory anyways, just in the stack instead of bss.
* Switch to C99 types (retaining compat with old compilers)Eric Wong2008-09-291-2/+2
| | | | | | | | | | | | | | | Seeing the "mpd_" prefix _everywhere_ is mind-numbing as the mind needs to retrain itself to skip over the first 4 tokens of a type to get to its meaning. So avoid having extra characters on my terminal to make it easier to follow code at 2:30 am in the morning. Please report any new issues you may come across on Free toolchains. I realize how difficult it can be to build/maintain cross-compiling toolchains and I have no intention of forcing people to upgrade their toolchains to build mpd. Tested with gcc 2.95.4 and and gcc 4.3.1 on x86-32.

| | | | We don't change the song pointer there, either.
* Move away from fprintf() when writing DB/state_fileEric Wong2008-09-181-1/+1
| | | | | | | | | I have serious trust issues when using stdio to write to the FS. So it's best to clean this code out so I can start figuring out what's wrong with Rasi's box not updating... None of these writes take place in a performance-critical setting anyways...
* playlist: don't pass "fd" to storedPlaylist.c functionsMax Kellermann2008-09-091-5/+3
| | | | | Return an "enum playlist_result" value instead of calling commandError() in storedPlaylist.c.
* playlist: don't pass "fd" to playlist.c functionsMax Kellermann2008-09-091-19/+29
| | | | | | The playlist library shouldn't talk to the client if possible. Introduce the "enum playlist_result" type which the caller (i.e. command.c) may use to generate an error message.
* playlist: showPlaylist() and shufflePlaylist() cannot failMax Kellermann2008-09-091-2/+2
| | | | Make them both return void.
* playlist: moved "repeat" and "random" value checks to command.cMax Kellermann2008-09-091-2/+2
| | | | | | | | Client's input values should be validated by the command implementation, and the core libraries shouldn't talk to the client directly if possible. Thus, setPlaylistRepeatStatus() and setPlaylistRandomStatus() don't get the file descriptor, and cannot fail (return void).
* playlist: added is_valid_playlist_name()Max Kellermann2008-09-091-0/+2
| | | | | | | | The function valid_playlist_name() checks the name, but it insists on reporting an eventual error to the client. The new function is_valid_playlist_name() is more generic: it just returns a boolean, and does not care what the caller will use it for. The old function valid_playlist_name() will be removed later.
* dbUtils, playlist, directory: pass constant pointersMax Kellermann2008-09-091-8/+8

* core rewrite (decode,player,outputBuffer,playlist)Eric Wong2008-08-161-17/+6
| | | | | | | | | | | | | This is a huge refactoring of the core mpd process. The queueing/buffering mechanism is heavily reworked. The player.c code has been merged into outputBuffer (the actual ring buffering logic is handled by ringbuf.c); and decode.c actually handles decoding stuff. The end result is several hundreds of lines shorter, even though we still have a lot of DEBUG statements left in there for tracing and a lot of assertions, too.
* clean up CPP includesMax Kellermann2008-04-121-3/+0
| | | | | | | | | 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

* Revert the queue implementation and commandsEric Wong2008-01-261-15/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's too ugly and broken (both technically and usability-wise) to be worth supporting in any stable release. In one sentence: The queue is a very crippled version of the playlist that takes precedence over the normal playlist. How is it crippled? * The "queueid" command only allows the queuing of songs ALREADY IN THE PLAYLIST! This promotes having the entire mpd database of songs in the playlist, which is a stupid practice to begin with. * It doesn't allow for meaningful rearranging and movement of songs within the queue. To move a song, you'd need to dequeue and requeue it (and other songs on the list). Why? The playlist already allows _all_ these features and shows everything a client needs to know about the ordering of songs in a _single_ command! * Random was a stupid idea to begin with and unfortunately we're stuck supporting it since we've always had it. Users should learn to use "shuffle" instead and not look at their playlists. Implementing queue because we have the problem of random is just a bandage fix and digging ourselves a new hole. This protocol addition was never in a stable release of mpd, so reverting it will only break things for people following trunk; which I'm not too worried about. I am however worried about long-term support of this misfeature, so I'm removing it. Additionally, there are other points: * It's trivially DoS-able: (while true; do echo queueid $song_id; done) | nc $MPD_HOST $MPD_PORT The above commands would cause the queue to become infinitely expanding, taking up all available memory in the system. The mpd playlist was implemented as an array with a fixed (but configurable) size limit for this reason. * It's not backwards-compatible. All clients would require upgrades (and additional complexity) to even know what the next song in the playlist is. mpd is a shared architecture, and we should not violate the principle of least astonishment here. This removes the following commands: queueid, dequeue, queueinfo Additionally, the status field of "playlistqueue: " is removed from the status command. While this DoS is trivial to fix, the design is simply too broken to ever support in a real release. The overloading of the "addid" command and the allowing of negative numbers to be used as offsets is far more flexible. This improved "addid" is completely backwards-compatible with all clients, and does not require clients to have UI changes or run additional commands to display the queue. git-svn-id: https://svn.musicpd.org/mpd/trunk@7155 09075e82-0dd4-0310-85a5-a0d7c8717e4f
* storedPlaylist: prevent potential DoS from stored playlist commandsEric Wong2008-01-261-0/+2
| | | | | | | | | | | | | | | | | | | | While mpd has always protected against the infinite expansion of the main playlist by limiting its size in memory, however the new storedPlaylist code has never checked for this limit. Malicious (or clumsy) users could repeatedly append songs to stored playlists, causing files to grow increasingly large on disk. Attempting to load extremely large files into memory will require mpd to slurp that all into memory, and ultimately the file would be unusable by mpd because of the configurable playlist size limit. Now we limit stored playlists to the max_playlist_length configuration variable set by the user (default is 16384). We will refuse to append to playlist files if they hit that limit; and also refuse to load more than the specified amount of songs into memory. git-svn-id: https://svn.musicpd.org/mpd/trunk@7154 09075e82-0dd4-0310-85a5-a0d7c8717e4f
* addToPlaylist/addSongToPlaylist: printId argument changed to added_idEric Wong2008-01-261-2/+2
| | | | | | | | | | | | 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 Wong2008-01-031-4/+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

* interface/connection malloc reductions from mpd-keEric Wong2006-07-301-29/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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
