* command: added command_success() and command_error()Max Kellermann2008-09-071-0/+28
| | | | | | | These two functions take a client struct instead of the file descriptor. We will now begin passing the client struct around instead of a raw file descriptor (which needed a linear lookup in the client list to be useful).
* audio: don't pass "fd" to {en,dis}ableAudioDevice()Max Kellermann2008-09-071-4/+14
| | | | No protocol code in the audio output library.
* volume: don't pass "fd" to changeVolumeLevel()Max Kellermann2008-09-071-4/+16
| | | | | The "volume" library shouldn't talk to the client. Move error handling to command.c.
* directory: don't pass "fd" to updateInit()Max Kellermann2008-09-071-5/+43
| | | | Again, move error handling to command.c.
* directory: printDirectoryInfo() does not call commandError()Max Kellermann2008-09-071-1/+3
| | | | Move another ocurrence of error handling over to command.c.
* directory: don't pass fd to traverseAllIn()Max Kellermann2008-09-071-4/+43
| | | | | | | | This patch continues the work of the previous patch: don't pass a file descriptor at all to traverseAllIn(). Since this fd was only used to report "directory not found" errors, we can easily move that check to the caller. This is a great relief, since it removes the dependency on a client connection from a lot of enumeration functions.
* playlist: PlaylistInfo() does not call commandError()Max Kellermann2008-09-071-2/+14
| | | | | | Continuing the effort of removing protocol specific calls from the core libraries: let the command.c code call commandError() based on PlaylistInfo's return value.
* playlist: don't pass "fd" to storedPlaylist.c functionsMax Kellermann2008-09-071-8/+23
| | | | | Return an "enum playlist_result" value instead of calling commandError() in storedPlaylist.c.
* playlist: don't pass "fd" to playlist.c functionsMax Kellermann2008-09-071-36/+126
| | | | | | 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 Kellermann2008-09-071-2/+4
| | | | Make them both return void.
* playlist: moved "repeat" and "random" value checks to command.cMax Kellermann2008-09-071-2/+18
| | | | | | | | 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).
* tag: moved code to tag_print.cMax Kellermann2008-09-071-0/+1
| | | | | Move everything which dumps a tag to a file descriptor to tag_print.c. This relaxes dependencies and splits the code into smaller parts.
* client: added client_write() and client_puts()Max Kellermann2008-09-071-2/+1
| | | | | | client_write() writes a buffer to the client and buffers it if required. client_puts() does the same for a C string. The next patch will add more tools which will replace fdprintf() later.
* include cleanupMax Kellermann2008-09-061-0/+1
| | | | As usual, include only headers which are really needed.
* tag: renamed functions, no CamelCaseMax Kellermann2008-08-291-1/+1
|
* export the function client_is_expired()Max Kellermann2008-08-291-2/+2
| | | | | | | Instead of passing the pointer to the "expired" flag to processListOfCommands(), this function should use the client API to check this flag. We can now remove the "global_expired" hack introduced recently.
* client: pass the client struct to processCommand()Max Kellermann2008-08-291-5/+9
| | | | | | | | Start exporting the client struct as an opaque struct. For now, pass it only to processCommand() and processListOfCommands(), and provide a function to extract the socket handle. Later, we will propagate the pointer to all command implementations, and of course to client_print() etc.
* include cleanupMax Kellermann2008-08-281-0/+1
| | | | Only include headers which are really needed.
* renamed player.c to player_control.cMax Kellermann2008-08-261-1/+1
| | | | | Give player.c a better name, meaning that the code is used to control the player thread.
* playlist: eliminate unused fd parametersMax Kellermann2008-08-261-8/+12
| | | | | Again, remove file descriptor parameters, which are not actually used. These functions can also be converted to return void.
* player: no "fd" and no return valueMax Kellermann2008-08-261-2/+5
| | | | | Most player*() functions do not actually use the file descriptor, and always return 0 (success). Eliminate them to get a leaner interface.
* moved struct AudioFormat to audio_format.hMax Kellermann2008-08-261-0/+1
| | | | | We want to expose the AudioFormat structure to plugins; remove some clutter by moving its declaration to a separate header file.
* enable -Wpointer-arith, -Wstrict-prototypesMax Kellermann2008-08-261-69/+129
| | | | | | Also enable -Wunused-parameter - this forces us to add the gcc "unused" attribute to a lot of parameters (mostly library callback functions), but it's worth it during code refactorizations.
* command.c: remove dead commented codeEric Wong2008-04-141-1/+0

* clean up CPP includesMax Kellermann2008-04-121-1/+2
| | | | | | | | | 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
* eliminated duplicate initializationMax Kellermann2008-03-261-2/+2

* Revert the queue implementation and commandsEric Wong2008-01-261-50/+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
* command: allow "addid" command to take an optional second argument, positionEric Wong2008-01-261-2/+14
| | | | | | | | | | | This will allow "addid \"song_url\" <pos>" to atomically insert a song at any given playlist position. If the add succeeds, but the actual movement fails (due to invalid position), then the song_id will be deleted before the command returns back to the client, and the client will get an error response. git-svn-id: https://svn.musicpd.org/mpd/trunk@7151 09075e82-0dd4-0310-85a5-a0d7c8717e4f

* addToPlaylist/addSongToPlaylist: printId argument changed to added_idEric Wong2008-01-261-2/+7
| | | | | | | | | | | | 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 Wong2008-01-031-6/+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

| | | | | | | | | | | | | | | | | Warren's fix in r4872 made phpMp work again, but also broke the unit tests completely (they work in this version). The version in 0.12.0 is far too buggy (it was from mpd-ke, what do you expect?). This one passes all the unit tests that the mpd-ke one passed, and should also work with phpMp when used with PHP magic quotes. This also means we can search on 100 (or more) tags at once, so no more arbitrary limits other than system memory. To run the unit tests, just do this: gcc -o t -DUNIT_TEST=1 src/buffer2array.c && ./t && echo OK git-svn-id: https://svn.musicpd.org/mpd/trunk@4874 09075e82-0dd4-0310-85a5-a0d7c8717e4f
* Replace strdup and {c,re,m}alloc with x* variants to check for OOM errorsEric Wong2006-08-261-1/+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
