2008-10-08directory: fix update in root directoryMax Kellermann1-2/+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.
2008-10-08directory: eliminate CamelCaseMax Kellermann1-2/+2
CamelCase is ugly, rename the functions.
2008-10-08database: renamed functions, "db_" prefix and no CamelCaseMax Kellermann1-15/+13
Yet another CamelCase removal patch.
2008-10-08directory: moved code to database.cMax Kellermann1-0/+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.
2008-10-08song: converted typedef Song to struct songMax Kellermann1-12/+23
Again, a data type which can be forward-declared.
2008-10-08directory: converted typedef Directory to struct directoryMax Kellermann1-6/+8
The struct can be forward-declared by other headers, which relaxes the header dependencies.
2008-10-07dbUtils/directory: traverseAllIn forEachSong returns -1 on errorEric Wong1-2/+2
Being consistent with most UNIX functions...
2008-10-07song: replace printSong* with song_print_*Eric Wong1-6/+6
This make argument order more consistent for iterators. Additionally, these now return ssize_t results for error checking.
2008-09-29Switch to C99 types (retaining compat with old compilers)Eric Wong1-1/+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.

2008-09-23Replace SongList with struct songvecEric Wong1-2/+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).
2008-09-08use strset.h instead of tagTracker.hMax Kellermann1-6/+17
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.
2008-09-07tag: don't pass "fd" to printVisitedInTagTracker()Max Kellermann1-1/+1
Pass the client struct instead of the raw file descriptor.
2008-09-07pass "struct client" to dbUtils.c, song.c, tag_print.cMax Kellermann1-34/+33
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.
2008-09-07directory: don't pass fd to traverseAllIn()Max Kellermann1-15/+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.
2008-09-07directory: don't pass fd to traverseAllIn() callbacksMax Kellermann1-36/+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.
2008-09-07playlist: don't pass "fd" to storedPlaylist.c functionsMax Kellermann1-4/+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 Kellermann1-2/+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.
2008-09-07song: moved code to song_print.c, song_save.cMax Kellermann1-0/+1
Move everything which dumps song information (via tag_print.c) to a separate source file. song_print.c gets code which writes song data to the client; song_save.c is responsible for serializing songs from the tag cache.
2008-09-06dbUtils, playlist, directory: pass constant pointersMax Kellermann1-9/+10
The usual bunch of const pointer conversions.
2008-08-29tag: converted MpdTag.items to a pointer listMax Kellermann1-2/+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.
2008-08-29tag: renamed MpdTag and MpdTagItem to struct tag, struct mpd_tag_itemMax Kellermann1-1/+1
Getting rid of CamelCase; not having typedefs also allows us to forward-declare the structures.
2008-08-26converted MpdTagItem.type to an enumMax Kellermann1-1/+1
Don't use CPP macros when you can use C enum... this also allows better type checking.
2008-08-26enable -Wpointer-arith, -Wstrict-prototypesMax Kellermann1-9/+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.
2008-03-26eliminated duplicate initializationMax Kellermann1-1/+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
2008-01-26addToPlaylist/addSongToPlaylist: printId argument changed to added_idEric Wong1-1/+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

2006-08-26Replace strdup and {c,re,m}alloc with x* variants to check for OOM errorsEric Wong1-5/+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

2006-07-30interface/connection malloc reductions from mpd-keEric Wong1-38/+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
