* flac: merged flacSendChunk() into flac_common_write()Max Kellermann2008-09-291-11/+6
| | | | | | | | | | | Since flacSendChunk() is a trivial function and is only used in one location, move the code there. The advantage is that calling decoder_data() directly returns the decoder_command value, so we can eliminate one decoder_get_command() call. [ew: using the terser API in the main branch, it always eliminated the dc_intr()/dc_seek() call, but I agree that killing a camel, err.. camelCase function is a good thing]
* flac: removed generic sample size supportMax Kellermann2008-09-291-31/+27
| | | | | | | | Support for bit rates except 16 bits (and 8 bits on little endian) has always been broken. Since we added optimized functions for 8, 16, 24/32 bits, we can remove the generic flac_convert() function. Instead of removing it, convert it to a wrapper function for flac_convert_*().
* flac: added special functions for 8 and 32 bitMax Kellermann2008-09-291-0/+37
| | | | | Same optimization for 8 and 32 bit files, like the previous patch for 16 bit. Along the way, this patch adds 24 bit FLAC support!
* flac: added optimized converter for 16 bitMax Kellermann2008-09-291-0/+17
| | | | | | flac_convert_16() runs a lot faster than the generic (and quite buggy) function flac_convert(). flac_convert_16() is only used for non-stereo files, since there is already flac_convert_stereo16().
* flac: use signed integers in flac_convert_stereo16()Max Kellermann2008-09-291-6/+4
| | | | | | By mistake, I casted the sample value to uint16_t, which is wrong. This patch simplifies the code by using a int16_t pointer instead of casting to int16_t* every time.
* flac: moved code from flacWrite() to _flac_common.cMax Kellermann2008-09-294-120/+90
| | | | | | | There is still a lot of duplicated code in flac_plugin.c and oggflac_plugin.c. Move code from flac_plugin.c to _flac_common.c, and use the new function flac_common_write() also in oggflac_plugin.c, porting lots of optimizations over to it.
* flac: assume the buffer is empty in flacWrite() IIMax Kellermann2008-09-291-6/+2
| | | | | The previous patch on this topic was incomplete: it still added data->chunk_length when calling flac_convert(). Remove this, too.
* directory: update playlist version if updatedEric Wong2008-09-281-1/+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.
* playlist: fix currentsong info after swapping songsEric Wong2008-09-281-0/+4
| | | | | | | | | | We forgot to update the playlist.queued marker if playlist.current changed. Additionally, if the queue cleared in any other mode, attempt to requeue (as it's a harmless no-op otherwise). Thanks to stonecrest for the bug report.
* playlist: reset after we've hit the endEric Wong2008-09-281-0/+6
| | | | | If repeat is off, we reset (and reshuffle in random mode) the playlist.
* advance to the next song on decoder errorsEric Wong2008-09-283-6/+17
| | | | | | Fix this regression introduced in the core rewrite so that we now skip to the next song when we encounter an error with the song we tried to decode.
* song: removed type SongListMax Kellermann2008-09-264-45/+2
| | | | SongList has been superseded by struct songvec.
* command: fix command "addid"Max Kellermann2008-09-261-1/+1
| | | | | | With patch 8d2830b3, I broke "addid": it did not return the id of the new song, because of a typo in the return condition (== instead of !=).
* Revert "directory: serialize freeSong() within the main thread"Eric Wong2008-09-231-9/+1
| | | | | | | | This reverts commit efefaee1f9535012be2fbfea8f0f870904daad5d. Conflicts: src/directory.c
* songvec: avoid free(NULL)Eric Wong2008-09-231-2/+4
| | | | Potentially broken free() implementations don't like it
* directory: use songvec_free to prevent memory leaks.Eric Wong2008-09-231-2/+1

* directory: fix leak introduced with threaded updateEric Wong2008-09-231-1/+1
| | | | | Use freeList() instead of free() to free all elements in the list.
* directory: serialize freeSong() within the main threadEric Wong2008-09-231-1/+10
| | | | | | | | | | | | | | | | | | It's possible the playlist will be accessing a song that is to be freed in the update thread. Rather than going through the complexity (and potential to make mistakes) of locking the playlist (as well as losing CPU cycles/pipelining due to barriers with mutexes), we'll just line up all songs to be freed in the main thread. It's relatively uncommon to call freeSong() heavily (as it is to update); so the extra, temporary memory usage won't be very noticeable. Additionally, if a song is renamed and it contains unique tag item; this has the additional side effect of preventing unnecessary fragmentation where an item is freed and shortly reallocated.
* log: remove umask() calls, just change open(2) argsEric Wong2008-09-221-8/+2
| | | | The umask calls were remants of when we used fopen().
* Remove EINTR checking for open(2)Eric Wong2008-09-222-4/+2
| | | | open(2) should only interrupt on "slow" devices, afaik...

* Merge branch 'ew/directory'Eric Wong2008-09-228-221/+102
|\ | | | | | | | | | | | | * ew/directory: songvec: remove songvec_prune directory: update do its work inside a thread directory: use enum update_return for return values
| * songvec: remove songvec_pruneEric Wong2008-09-223-27/+0
| | | | | | | | | | | | Any pruned files will be noticed during update and pruned from the live database, so this inefficient function can go away and never come back.
| * directory: update do its work inside a threadEric Wong2008-09-225-125/+56
| | | | | | | | | | | | | | | | | | A lot of the preparation was needed (and done in previous months) in making update thread-safe, but here it is. This was the first thing I made work inside a thread when I started mpd-uclinux many years ago, and also the last thing I've done in mainline mpd to work inside a thread, go figure.
| * directory: use enum update_return for return valuesEric Wong2008-09-221-72/+49
| | | | | | | | This way we avoid having to document -1, 0, 1

|\| | | | | | | | | | | | | | | | | | | * ew/directory: Don't try to prune unless we're updating workaround race condition on updates with broken signal blocking Replace SongList with struct songvec directory: remove unused updateMp3Directory() function start using prefixcmp() Add prefixcmp() (stol^H^H^H^Hborrowed from git)
| * Don't try to prune unless we're updatingEric Wong2008-09-201-1/+2
| | | | | | | | | | | | Pruning is very expensive and we won't need it in the future anyways. This brings startup back to previous speeds (before songvec changes).
| * workaround race condition on updates with broken signal blockingEric Wong2008-09-201-39/+50
| | | | | | | | | | | | | | | | | | pthreads with our existing signal blocking/handling is broken, for now just sleep a bit in the child to prevent the CHLD handler from being called too early. Also, improve error reporting when handling SIGCHLD by storing the status to be called in the main task (which can be logged, since we can't do logging inside the sig handler).
| * Replace SongList with struct songvecEric Wong2008-09-208-136/+226
| | | | | | | | | | | | | | 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).
| * directory: remove unused updateMp3Directory() functionEric Wong2008-09-202-20/+0
| | | | | | | | | | | | | | | | | | | | | | | | It hasn't been used in many years commit 3a89afdd80f228139554372a83a9d74486acf691 Author: Warren Dukes <warren.dukes@gmail.com> Date: Sat Nov 20 20:28:32 2004 +0000 remove --update-db option (SVN r2719)
| * start using prefixcmp()Eric Wong2008-09-208-58/+29
| | | | | | | | | | LOC reduction and less noise makes things easier for tired old folks to follow.
| * Add prefixcmp() (stol^H^H^H^Hborrowed from git)Eric Wong2008-09-202-0/+12
| | | | | | | | | | | | | | This allows us to avoid the nasty repetition in strncmp(foo, bar, strlen(foo)). We'll miss out on the compiler optimizing strlen() into sizeof() - 1 for string literals for this; but we don't use this it for performance-critical functions anyways...

* Move away from fprintf() when writing DB/state_fileEric Wong2008-09-1810-55/+60
| | | | | | | | | I have serious trust issues when using stdio to write to the FS. So it's best to clean this code out so I can start figuring out what's wrong with Rasi's box not updating... None of these writes take place in a performance-critical setting anyways...

* Directory: don't allocate stat information dynamicallyEric Wong2008-09-182-50/+22
| | | | | | | This should save a few thousand ops. Not worth it to malloc for such a small (3-words on 32-bit ARM and x86) structures. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* mp3: fix long line, I can't read past 80 colsEric Wong2008-09-171-1/+2
|
* mp3: fix buffer overflow when max_frames is too largeMax Kellermann2008-09-171-0/+5
| | | | | | | The function decodeFirstFrame() allocates memory based on data from the mp3 header. This can make the buffer size allocation overflow, or lead to a DoS attack with a very large buffer. Cap this buffer at 8 million frames, which should really be enough for reasonable files.
* client: check expired after client_process_line()Max Kellermann2008-09-171-1/+2
| | | | | | The assertion on "!client_is_expired(client)" was wrong, because writing the command response may cause the client to become expired. Replace that assertion with a check.
* mp4: fix potential integer overflow bug in the mp4_decode() functionTerry2008-09-121-0/+7
| | | | | | | | | | A crafted mp4 file could cause an integer overflow in mp4_decode function in src/inputPlugins/mp4_plugin.c. mp4ff_num_samples() function returns some tainted value. sizeof(float) * numSamples is an integer overflow operation if numSamples is too huge, so xmalloc will allocate a small memory region. I constructe a mp4 file, and use faad2 to open the file. mp4ff_num_samples() returns -1. So I think mpd bears from the same problem.

| * client: shorten names of the struct client variablesEric Wong2008-09-121-210/+209
| | | | | | | | | | | | | | | | | | Seeing the token "client" repeatedly in the same blocks of code adds to mental fatigue and makes it harder to follow code because there's fewer unique tokens to distinguish. "cl" is unique within mpd and conveys enough information to be useful to anybody reading the code.
| * client: simplified client_read()Max Kellermann2008-09-101-3/+5
| | | | | | | | Remove one comparison by changing branch order.
| * client: client_input_received() returns 0Max Kellermann2008-09-101-4/+2
| | | | | | | | | | | | | | | | | | Since the caller chain doesn't care about the return value (except for COMMAND_RETURN_KILL, COMMAND_RETURN_CLOSE), just return 0 if there is nothing special. This saves one local variable initialization, and one access to it. Also remove one unreachable "return 1" from client_read().
| * client: check for COMMAND_RETURN_CLOSEMax Kellermann2008-09-101-15/+14
| | | | | | | | | | | | | | Don't close the client within client_process_line(), return COMMAND_RETURN_CLOSE instead. This is the signal for the caller chain to actually close it. This makes dealing with the client pointer a lot safer, since the caller always knows whether it is still valid.
| * client: renamed local variable "selret" to "ret"Max Kellermann2008-09-101-4/+5
| | | | | | | | It's easier to reuse the variable if it has a more generic name.
| * client: moved CLOSE/KILL check after client_process_line()Max Kellermann2008-09-101-4/+3
| | | | | | | | Don't update client data if it is going to be closed anyway.
| * client: don't check FD_ISSET(client->fd) on expired clientMax Kellermann2008-09-091-1/+2
| | | | | | | | | | client->fd becomes -1 when the client expires. Don't use FD_ISSET() with this expired client; doing so would cause a crash due to SIGBUS.
