LOC reduction and less noise makes things easier for tired old folks to follow.

2008-09-18Move away from fprintf() when writing DB/state_fileEric Wong1-2/+3
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...
2008-09-09volume: don't pass "fd" to changeVolumeLevel()Max Kellermann1-16/+9
The "volume" library shouldn't talk to the client. Move error handling to command.c.
2008-09-02volume: include outputBuffer.h for ob_set_sw_volumeEric Wong1-0/+1
2008-08-30enable -Wpointer-arith, -Wstrict-prototypesMax Kellermann1-1/+1
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.
2008-08-16core rewrite (decode,player,outputBuffer,playlist)Eric Wong1-2/+1
This is a huge refactoring of the core mpd process. The queueing/buffering mechanism is heavily reworked. The player.c code has been merged into outputBuffer (the actual ring buffering logic is handled by ringbuf.c); and decode.c actually handles decoding stuff. The end result is several hundreds of lines shorter, even though we still have a lot of DEBUG statements left in there for tracing and a lot of assertions, too.
2008-04-12clean up CPP includesMax Kellermann1-1/+3
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

2008-01-03Cleanup #includes of standard system headers and put them in one placeEric Wong1-7/+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

2007-01-14Don't initialize globals to zero (or NULL)Eric Wong1-1/+1
Some compilers and linkers aren't smart enough to optimize this, as global variables are implictly initialized to zero. As a result, binaries are a bit smaller as more goes in the .bss and less in the text section. git-svn-id: https://svn.musicpd.org/mpd/trunk@5254 09075e82-0dd4-0310-85a5-a0d7c8717e4f
2006-08-26Replace strdup and {c,re,m}alloc with x* variants to check for OOM errorsEric Wong1-1/+1
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

2006-07-30commandError() cleanups, fixup gcc checksEric Wong1-5/+3
stripped binary size reduced by 9k on my machine from making commandError a function. We'll print out error messages slightly slower before, but the smaller binary is more than worth it. git-svn-id: https://svn.musicpd.org/mpd/trunk@4488 09075e82-0dd4-0310-85a5-a0d7c8717e4f
2006-07-30interface/connection malloc reductions from mpd-keEric Wong1-10/+10
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

2006-07-17alsa: fix memory leaks from snd_*_open*()Eric Wong1-1/+3
ALSA uses a global config structure that's overwritten (and not free'd) every time one of those functions is called, so we have to manually call snd_config_update_free_global() to release it. Hint taken from MEMORY-LEAK in the ALSA source code git-svn-id: https://svn.musicpd.org/mpd/trunk@4381 09075e82-0dd4-0310-85a5-a0d7c8717e4f
2006-07-17sparse: ANSI-fy function declarationsEric Wong1-7/+7
These are just warnings from sparse, but it makes the output easier to read. I ran this through a quick perl script, but of course verified the output by looking at the diff and making sure the thing still compiles. here's the quick perl script I wrote to generate this patch: ----------- 8< ----------- use Tie::File; defined(my $pid = open my $fh, '-|') or die $!; if (!$pid) { open STDERR, '>&STDOUT' or die $!; exec 'sparse', @ARGV or die $!; } my $na = 'warning: non-ANSI function declaration of function'; while (<$fh>) { print STDERR $_; if (/^(.+?\.[ch]):(\d+):(\d+): $na '(\w+)'/o) { my ($f, $l, $pos, $func) = ($1, $2, $3, $4); $l--; tie my @x, 'Tie::File', $f or die "$!: $f"; print '-', $x[$l], "\n"; $x[$l] =~ s/\b($func\s*)\(\s*\)/$1(void)/; print '+', $x[$l], "\n"; untie @x; } } git-svn-id: https://svn.musicpd.org/mpd/trunk@4378 09075e82-0dd4-0310-85a5-a0d7c8717e4f
2006-07-16OSS: handle device disconnects and reconnects (w/o needing a mpd restart)Eric Wong1-8/+26
