2008-09-07tag: added buffered versions of the tag_print.c codeMax Kellermann1-3/+20
Currently, when the tag cache is being serialized to hard disk, the stdio buffer is flushed before every song, because tag_print.c performs unbuffered writes on the raw file descriptor. Unfortunately, the fdprintf() API allows buffered I/O only for a client connection by looking up the client pointer owning the file descriptor - for stdio, this is not possible. To re-enable proper stdio buffering, we have to duplicate the tag_print.c code without fprintf() instead of our custom fdprintf() hack. Add this duplicated code to tag_save.c.
2008-09-07song: moved code to song_print.c, song_save.cMax Kellermann1-186/+3
Move everything which dumps song information (via tag_print.c) to a separate source file. song_print.c gets code which writes song data to the client; song_save.c is responsible for serializing songs from the tag cache.
2008-09-07tag: moved code to tag_print.cMax Kellermann1-0/+1
Move everything which dumps a tag to a file descriptor to tag_print.c. This relaxes dependencies and splits the code into smaller parts.
2008-09-06tag: fix segfault on updateEric Wong1-0/+1
clearMpdTag could be called on a tag that was still in a tag_begin_add transaction before tag_end_add is called. This was causing free() to attempt to operate on bulk.items; which is un-free()-able. Now instead we unmark the bulk.busy to avoid committing the tags to the heap only to be immediately freed. Additionally, we need to remember to call tag_end_add() when a song is updated before we NULL song->tag to avoid tripping an assertion the next time tag_begin_add() is called.
2008-08-29tag: try not to reallocate tag.items in every add() callMax Kellermann1-4/+16
If many tag_items are added at once while the tag cache is being loaded, manage these items in a static fixed list, instead of reallocating the list with every newly created item. This reduces heap fragmentation. Massif results again: mk before: total 12,837,632; useful 10,626,383; extra 2,211,249 mk now: total 12,736,720; useful 10,626,383; extra 2,110,337 The "useful" value is the same since this patch only changes the way we allocate the same amount of memory, but heap fragmentation was reduced by 5%.
2008-08-29song: don't export newNullSong()Max Kellermann1-1/+1
The function newNullSong() is only used internally in song.c.

2008-08-26renamed inputPlugin.* to decoder_list.*Max Kellermann1-1/+1
Since inputPlugin.c manages the list of registered decoders, we should rename the source file.
2008-08-26renamed InputPlugin to struct decoder_pluginMax Kellermann1-2/+3
"decoder plugin" is a better name than "input plugin", since the plugin does not actually do the input - InputStream does. Also don't use typedef, so we can forward-declare it if required.
2008-03-26fix segmentation fault in song info parserMax Kellermann1-4/+5
The database parser does not check whether the song object has been initialized yet, which may lead to a NULL pointer dereference. Add this check. git-svn-id: https://svn.musicpd.org/mpd/trunk@7201 09075e82-0dd4-0310-85a5-a0d7c8717e4f

2008-01-03Cleanup #includes of standard system headers and put them in one placeEric Wong1-3/+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

thread-safety work in preparation for rewrite to use pthreads Expect no regressions against trunk (r7078), possibly minor performance improvements in update (due to fewer heap allocations), but increased stack usage. Applied the following patches: * maxpath_str for reentrancy (temporary fix, reverted) * path: start working on thread-safe variants of these methods * Re-entrancy work on path/character-set conversions * directory.c: exploreDirectory() use reentrant functions here * directory/update: more use of reentrant functions + cleanups * string_toupper: a strdup-less version of strDupToUpper * get_song_url: a static-variable-free version of getSongUrl() * Use reentrant/thread-safe get_song_url everywhere * replace rmp2amp with the reentrant version, rmp2amp_r * Get rid of the non-reentrant/non-thread-safe rpp2app, too. * buffer2array: assert strdup() returns a usable value in unit tests * replace utf8ToFsCharset and fsCharsetToUtf8 with thread-safe variants * fix storing playlists w/o absolute paths * parent_path(), a reentrant version of parentPath() * parentPath => parent_path for reentrancy and thread-safety * allow "make test" to automatically run embedded unit tests * remove convStrDup() and maxpath_str() * use MPD_PATH_MAX everywhere instead of MAXPATHLEN * path: get rid of appendSlash, pfx_path and just use pfx_dir * get_song_url: fix the ability to play songs in the top-level music_directory git-svn-id: https://svn.musicpd.org/mpd/trunk@7106 09075e82-0dd4-0310-85a5-a0d7c8717e4f

2007-01-14Don't initialize globals to zero (or NULL)Eric Wong1-3/+3

2006-08-26Replace strdup and {c,re,m}alloc with x* variants to check for OOM errorsEric Wong1-5/+6
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

2006-07-30interface/connection malloc reductions from mpd-keEric Wong1-9/+9
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

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
