2008-09-07playlist: don't pass "fd" to showPlaylist(), playlistChangesPosId()Max Kellermann1-2/+2
Pass the client struct instead of the raw file descriptor.
2008-09-07playlist: pass struct client to loadPlaylist()Max Kellermann1-1/+1
The function loadPlaylist() wants to report incremental errors to the client, for this reason we cannot remove its protocol dependency right now. Instead, make it use the client struct instead of the raw file descriptor.
2008-09-07pass "struct client" to dbUtils.c, song.c, tag_print.cMax Kellermann1-6/+8
Don't pass the raw file descriptor around. This migration patch is rather large, because all of the sources have inter dependencies - we have to change all of them at the same time.
2008-09-07playlist: don't pass "fd" to storedPlaylist.c functionsMax Kellermann1-5/+3
Return an "enum playlist_result" value instead of calling commandError() in storedPlaylist.c.
2008-09-07playlist: don't pass "fd" to playlist.c functionsMax Kellermann1-19/+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.
2008-09-07playlist: showPlaylist() and shufflePlaylist() cannot failMax Kellermann1-2/+2
Make them both return void.
2008-09-07playlist: moved "repeat" and "random" value checks to command.cMax Kellermann1-2/+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).
2008-09-07playlist: added is_valid_playlist_name()Max Kellermann1-0/+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.
2008-09-06dbUtils, playlist, directory: pass constant pointersMax Kellermann1-8/+8
The usual bunch of const pointer conversions.
2008-08-28include cleanupMax Kellermann1-1/+1
Only include headers which are really needed.
2008-08-26playlist: eliminate unused fd parametersMax Kellermann1-4/+4
Again, remove file descriptor parameters, which are not actually used. These functions can also be converted to return void.
2008-04-12clean up CPP includesMax Kellermann1-3/+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

2008-01-26Revert the queue implementation and commandsEric Wong1-15/+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
2008-01-26storedPlaylist: prevent potential DoS from stored playlist commandsEric Wong1-0/+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
2008-01-26addToPlaylist/addSongToPlaylist: printId argument changed to added_idEric Wong1-2/+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
2008-01-03Cleanup #includes of standard system headers and put them in one placeEric Wong1-4/+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

2006-07-30interface/connection malloc reductions from mpd-keEric Wong1-29/+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
