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

2006-07-17sparse: ANSI-fy function declarationsEric Wong1-1/+1
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

2004-11-11ok, tagtracker now tracks title, this has the disadvantage of needing to sortWarren Dukes1-7/+8
the title tracker list, and it wastes more memory. But it makes implementing list command elegant, since we've just visit tags, then print out the visited tags in tag tracker (which has the benefit of making sure everything is in sorted order) git-svn-id: https://svn.musicpd.org/mpd/trunk@2608 09075e82-0dd4-0310-85a5-a0d7c8717e4f

2004-11-11ok, optimize memory sage of directorys, by iteratively creating the directories,Warren Dukes1-6/+8
this code needs some serious testing: Note: The song name optimization i think is worth it, saves about 200k of ram on my syste, however, having to create directory names iteratively each time we print probably isn't worth the cpu. We only save about 10k of ram for the computer todo alot more work, and the code maybe a little messier git-svn-id: https://svn.musicpd.org/mpd/trunk@2604 09075e82-0dd4-0310-85a5-a0d7c8717e4f
