2009-01-02database: use GLib instead of utils.hMax Kellermann1-2/+3
2009-01-01event_pipe: added pipe_event enum and callbacksMax Kellermann1-1/+0
Make the event_pipe (formerly main_notify) send/receive a set of events, with a callback for each one. The default event PIPE_EVENT_SIGNAL does not have a callback. It is still there for waking up the main thread, when it is waiting for the player thread.
2009-01-01event_pipe: renamed functions from main_notify_* to event_pipe_*Max Kellermann1-1/+1
Continuing the previous patch.
2009-01-01main_notify: renamed source to event_pipe.cMax Kellermann1-1/+1
We are going to migrate away from the concept of notifying the main thread. There should be events sent to it instead. This patch starts a series to implement that.
2008-12-29database: use GLib loggingMax Kellermann1-36/+38
2008-12-29removed os_compat.hMax Kellermann1-1/+6
Only include headers which are really needed. os_compat.h aimed to make MPD easily portable, but was never actually made portable.
2008-12-28utils: removed myFgets()Max Kellermann1-3/+7
Replaced myFgets() with fgets() + g_strchomp().
2008-11-05path: no CamelCaseMax Kellermann1-2/+2
Rename variables and functions.
2008-10-28utils: use g_str_has_prefix() instead of prefixcmp()Max Kellermann1-2/+2
Remove duplicated code from MPD.
2008-10-20path: replaced parent_path() with g_path_get_dirname()Max Kellermann1-4/+7
Again, GLib's version is more robust than ours.
2008-10-09update: make the job id unsignedMax Kellermann1-1/+1
Since the return value cannot be -1 anymore, we can make it unsigned.
2008-10-09update: job ID must be positiveMax Kellermann1-1/+1
The documentation for directory_update_init() was incorrect: a job ID must be positive, not non-negative. If the update queue is full and no job was created, it makes more sense to return 0 instead of -1, because it is more consistent with the return value of isUpdatingDB().
2008-10-09update: don't export updateDirectory()Max Kellermann1-1/+13
If the user requests database update during startup, call directory_update_init(). This should be changed to fully asynchronous update later. For this to work, main_notify has to be initialized before db_init().
2008-10-09database: renamed get_get_song() to db_get_song()Max Kellermann1-2/+2
Search'n'replace typo..
2008-10-09diretory: moved code to directory_save.c, directory_print.cMax Kellermann1-0/+1
Remove clutter from directory.c. Everything which saves or loads to/from the hard disk goes to directory_save.c, and code which sends directory information to the client is moved into directory_print.c.
2008-10-09database: removed local variable bufferSizeMax Kellermann1-3/+2
Use sizeof(buffer) instead.
2008-10-09database: simplify db_load()Max Kellermann1-47/+42
Removed a superfluous closure.
2008-10-08directory: path must not be NULLMax Kellermann1-2/+2
For the root directory, let's set path to an empty string. This saves a few checks.
2008-10-08directory: eliminate CamelCaseMax Kellermann1-10/+9
CamelCase is ugly, rename the functions.
2008-10-08database: renamed functions, "db_" prefix and no CamelCaseMax Kellermann1-19/+26
Yet another CamelCase removal patch.
2008-10-08database: removed printDirectoryInfo()Max Kellermann1-10/+0
The same can be achieved with directory_print(db_get_directory()).
2008-10-08directory: moved code to database.cMax Kellermann1-265/+54
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.
2008-10-08directory: converted isRootDirectory() to an inline functionMax Kellermann1-5/+5
The function isRootDirectory() is tiny and can be converted to an inline function. Don't allow name==NULL.
2008-10-08song: removed CamelCaseMax Kellermann1-1/+1
CamelCase is ugly... rename all functions.
2008-10-08song: converted typedef Song to struct songMax Kellermann1-6/+7
Again, a data type which can be forward-declared.
2008-10-08directory: converted typedef Directory to struct directoryMax Kellermann1-28/+33
The struct can be forward-declared by other headers, which relaxes the header dependencies.
2008-10-08update: merged exploreDirectory() into updateDirectory()Max Kellermann1-1/+1
exploreDirectory() duplicates some code in updateDirectory(). Merge both functions, and use directory_is_empty() to determine whether update or explore mode should be used.
2008-10-08directory: added directory_is_empty()Max Kellermann1-1/+1
directory_is_empty() is a tiny inline function which determine if a directory has any child objects (sub directories or songs).
2008-10-08directory: moved code to update.cMax Kellermann1-575/+17
The source directory.c mixes several libraries: directory object management, database management and database update, resulting in a 1000+ line monster. Move the whole database update code to update.c.
2008-10-07directory: fix return value in removeDeletedFromDirectoryEric Wong1-1/+1
oops :x
2008-10-07directory: serialize song deletes from playlist during updateEric Wong1-3/+28
This makes the update code thread-safe and doesn't penalize the playlist code by complicating it with complicated and error-prone locks (and the associated overhead, not everybody has a thread-implementation as good as NPTL). The update task blocks during the delete; but the update task is a slow task anyways so we can block w/o people caring too much. This was also our only freeSong call site, so remove that function. Note that deleting entire directories is not fully thread-safe, yet; as their traversals are not yet locked.
2008-10-07directory: use songvec_for_each for iteratorsEric Wong1-28/+30
Get rid of songvec_write so we can enforce proper locking
2008-10-07dbUtils/directory: traverseAllIn forEachSong returns -1 on errorEric Wong1-12/+9
Being consistent with most UNIX functions...
2008-10-07Assert if we don't have song or song->url setEric Wong1-2/+2
song objects cannot exist without a path or URL
2008-10-06song: stop storing song_typeEric Wong1-1/+1
We already know if a song is a URL or not based on whether it has parentDir defined or not. Hopefully one day in the future we can drop HTTP support from MPD entirely when an HTTP filesystem comes along and we can access streams via open(2).
2008-10-06song: use flex arrays to store song->urlEric Wong1-1/+1
Reduce the number of allocations we make, so there's less pressure on the allocator and less overhead to keep track of the allocations in.
2008-10-06directory: reuse existing directory if found on updateEric Wong1-4/+9
Instead of allocating a new one, just reuse an existing one if one is found when rereading the DB. This is a small makes the previous commit work on subdirectories of the root music directory. [1] "song: better handling of existing songs when rereading DB"
2008-10-06directory: simplify list update handling logicEric Wong1-45/+60
Now the "update" command can be issued multiple times regardless of whether the client is in list mode or not. We serialize the update tasks to prevent updates from trampling over each other and will spawn another update task once the current one is finished updating and reaped. Right now we cap the queue size to 32 which is probably enough (I bet most people usually run update with no argument anyways); but we can make it grow/shrink dynamically if needed. There'll still be a hard-coded limit to prevent DoS attacks, though.
2008-10-06directory: streamline deletesEric Wong1-17/+15
Instead of relying on the shortname, just pass the song pointer to prevent redundant lookups during deletes.
2008-09-29directory: isRootDirectory() is a one-linerEric Wong1-4/+1
Improving the signal to noise ratio...
2008-09-29directory: writeDirectoryInfo propagates errorsEric Wong1-21/+19
If a write failed, it's a good sign subsequent writes will fail, too, so propgate errors all the way up the stack.
2008-09-29directory: make it clear that DIRECTORY_MTIME is deprecatedEric Wong1-1/+1
A long time ago in an mpd far away...
2008-09-29directory: remove "Mp3" referencesEric Wong1-17/+17
MPD has supported more audio formats than just MP3 for over five years...
2008-09-29directory: remove shortname arguments everywhereEric Wong1-80/+41
It was a huge confusing mess of parameter passing around and around. Add a few extra assertions to ensure we're handling parent/child relationships properly.
2008-09-29directory: replace DirectoryList with dirvecEric Wong1-195/+96
Small memory reduction compared to songvec since most users have much fewer dirs than songs, but still nice to have.
2008-09-29directory: remove unused CPP definesEric Wong1-4/+0
We no longer for for updates
2008-09-29songvec_free => songvec_destroyEric Wong1-1/+1
"free" implies the songvec structure itself is freed, which is not the case.
2008-09-29directory.c: kill unnecessary includesEric Wong1-4/+1
2008-09-29directory: update playlist version if updatedEric Wong1-1/+6
If we updated the mpd metadata database; then there's a chance some of those songs in the playlist will have updated metadata. So be on the safe side and increment the playlist version number if _any_ song changed (this is how all released versions of mpd did it, too). This bug was introduced recently when making "update" threaded. Thanks to stonecrest for the bug report.
2008-09-23directory: fix leak introduced with threaded updateEric Wong1-1/+1
Use freeList() instead of free() to free all elements in the list.
