      Standardize state_file handling routines. · 12aec573
      Eric Wong authored 
      This way it's easier to manage and extend.

      remove deprecated myfprintf wrapper · 381d7232
      Eric Wong authored 
      This shaves another 5-6k because we've removed the paranoid
fflush() calls after every fprintf.  Now we only fflush()
when we need to

      interface/connection malloc reductions from mpd-ke · 4cf5d04c
      Eric Wong authored 
      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).

      sparse: ANSI-fy function declarations · a234780a
      Eric Wong authored 
      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;
}
}

      rewrite statefile code for audio devices · a25acbc9
      Eric Wong authored 
      In the words of the original author, it was 'crappy'.  I tend to
agree :)

The code has also been broken for at least the past few months,
and nobody bothered fixing it

The previous format it was overly complex: 5 lines to describe
each device.  The new format is one-line per-device:

audio_device_state:%d:%s

%d - 0 for disabled, any integer for enabled
%s - name of the device as specified in the config file,
whitespace and all

Incompatibilities:

* Output names are now _required_ to be unique.

This is required because the new format relies solely on the
name of the audio device.

Relying on the device IDs internal to MPD was a bad idea
anyways since the user usually has none or very little idea
how they're generated, and adding a new device or removing
one from a config would throw things off completely.

This is also just a Good Idea(TM) because it makes things
less confusing to users when they see it in their clients.

* Output states are not preserved from the previous format.

Not a big deal, since the previous code was never officially
released.  Also, it's been broken for months now, so I doubt
anybody would notice :)
