* Avoid calling isRootDirectory when we have a directory objectEric Wong2008-10-121-2/+2
| | | | | There is only one music_root and we can just compare addresses.
* directory: don't use identical struct and variable namesEric Wong2008-10-111-5/+5
| | | | | | Duplicated tokens in close proximity takes too long for my head to parse; and "dir" is an easy and common abbreviation for "directory".
* directory: fix update in root directoryMax Kellermann2008-10-111-3/+2
| | | | | | | Commit 0bfe7802 broke update for new files in the root directory, because music_root->path was an empty string and not NULL. There were some NULL tests missing. Change them to !isRootDirectory(path) instead of path!=NULL.
* directory: eliminate CamelCaseMax Kellermann2008-10-111-2/+2
| | | | | | | | CamelCase is ugly, rename the functions. [ew: "directory_get_directory" was too confusing, using "directory_get_subdir" instead (old function was named "getSubDirectory")]
* database: renamed functions, "db_" prefix and no CamelCaseMax Kellermann2008-10-111-11/+11
| | | | Yet another CamelCase removal patch.
* directory: moved code to database.cMax Kellermann2008-10-111-1/+1
| | | | | | Taming the directory.c monster, part II: move the database management stuff to database. directory.c should only contain code which works on directory objects.
* song: converted typedef Song to struct songMax Kellermann2008-10-111-9/+10
| | | | | | | | | | | | | | | 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 ]
* directory: converted typedef Directory to struct directoryMax Kellermann2008-10-111-6/+5
| | | | | The struct can be forward-declared by other headers, which relaxes the header dependencies.

| * dbUtils: more cleanupsEric Wong2008-10-071-11/+3
| | | | | | | | | | | | | | Remove unnecessary wrapper function now that we have song_print_url_x and also return the results directly since we'll know the song_print_* functions will all return -1 on error.

| * song: replace printSong* with song_print_*Eric Wong2008-10-051-8/+7
| | | | | | | | | | | | This make argument order more consistent for iterators. Additionally, these now return ssize_t results for error checking.
* | dbUtils: remove C99 initializerEric Wong2008-10-051-3/+2
|/ | | | | | | Upgrading a toolchain is still a nasty operation and they're never easy to build, so don't force people to upgrade from their old compilers (especially since some people are still stuck with Linux 2.4 and gcc 2.95).
* Switch to C99 types (retaining compat with old compilers)Eric Wong2008-09-291-1/+1
| | | | | | | | | | | | | | | 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.

* Replace SongList with struct songvecEric Wong2008-09-201-2/+2
| | | | | | | Our linked-list implementation is wasteful and the SongList isn't modified enough to benefit from being a linked list. So use a more compact array of song pointers which saves ~200K on a library with ~9K songs (on x86-32).
* Merge branch 'mk/strset' into mk/playlistEric Wong2008-09-091-12/+18
|\ | | | | | | | | | | | | | | | | | | | | * mk/strset: use strset.h instead of tagTracker.h strset: fix duplicate values added string set library Conflicts: src/dbUtils.c src/tagTracker.c
| * use strset.h instead of tagTracker.hMax Kellermann2008-09-091-10/+28
| | | | | | | | | | | | | | With a large music database, the linear string collection in tagTracker.c becomes very slow. We implemented that in a quick'n'dirty fashion when we removed tree.c, and now we rewrite it using the fast hashed string set.
* | directory: don't pass fd to traverseAllIn()Max Kellermann2008-09-091-15/+15
| | | | | | | | | | | | | | | | 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.
* | directory: don't pass fd to traverseAllIn() callbacksMax Kellermann2008-09-091-36/+67
| | | | | | | | | | | | | | | | | | | | Database traversal should be generic, and not bound to a client connection. This is the first step: no file descriptor for the callback functions forEachSong() and forEachDir(). If a callback needs the file descriptor, it has to be passed in the void*data pointer somehow; some callbacks might need a new struct for passing more than one parameter. This might look a bit cumbersome right now, but our goal is to have a clean API.
* | playlist: don't pass "fd" to storedPlaylist.c functionsMax Kellermann2008-09-091-4/+3
| | | | | | | | | | Return an "enum playlist_result" value instead of calling commandError() in storedPlaylist.c.
* | playlist: don't pass "fd" to playlist.c functionsMax Kellermann2008-09-091-2/+2
| | | | | | | | | | | | 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.
* | dbUtils, playlist, directory: pass constant pointersMax Kellermann2008-09-091-9/+10
|/ | | | The usual bunch of const pointer conversions.
* tag: converted MpdTag.items to a pointer listMax Kellermann2008-09-021-2/+2
| | | | | | This prepares the following patches, which aim to reduce MPD's memory usage: we plan to share tag_item instances, instead of just their values.
* tag: renamed MpdTag and MpdTagItem to struct mpd_tag, struct tag_itemMax Kellermann2008-09-021-1/+1
| | | | | Getting rid of CamelCase; not having typedefs also allows us to forward-declare the structures.
* converted MpdTagItem.type to an enumMax Kellermann2008-08-301-1/+1
| | | | | Don't use CPP macros when you can use C enum... this also allows better type checking.
* enable -Wpointer-arith, -Wstrict-prototypesMax Kellermann2008-08-301-9/+13
| | | | | | 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.
* eliminated duplicate initializationMax Kellermann2008-03-261-1/+1
| | | | | | | Local variables which are never read before the first assignment don't need initialization. Saves a few bytes of text. Also don't reset variables which are never read until function return. git-svn-id: https://svn.musicpd.org/mpd/trunk@7199 09075e82-0dd4-0310-85a5-a0d7c8717e4f
* addToPlaylist/addSongToPlaylist: printId argument changed to added_idEric Wong2008-01-261-1/+1
| | | | | | | | | | | | 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

* Replace strdup and {c,re,m}alloc with x* variants to check for OOM errorsEric Wong2006-08-261-5/+5
| | | | | | | | | | | | | | | | | | | 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

* interface/connection malloc reductions from mpd-keEric Wong2006-07-301-38/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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
