2008-04-12clean up CPP includesMax Kellermann1-2/+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
2008-04-12provide switches for TCP and unix socketsMax Kellermann1-0/+4
autoconf flags for enabling and disabling TCP and unix domain socket support. Embedded machines without a TCP stack may be better off without TCP support. git-svn-id: https://svn.musicpd.org/mpd/trunk@7236 09075e82-0dd4-0310-85a5-a0d7c8717e4f
2008-04-12fix sign compare warningsMax Kellermann1-1/+1
Do explicit casts before comparing signed with unsigned. The one in log.c actually fixes another warning: in the expanded macro, there may be a check "logLevel>=0", which is always true. git-svn-id: https://svn.musicpd.org/mpd/trunk@7230 09075e82-0dd4-0310-85a5-a0d7c8717e4f

* move set_nonblock{,ing}() into utils.c since we use it elsewhere, too * add proper error checking to set_nonblocking() * use os_compat.h instead of individually #includ-ing system headers git-svn-id: https://svn.musicpd.org/mpd/trunk@7217 09075e82-0dd4-0310-85a5-a0d7c8717e4f
2008-03-26unsigned countersMax Kellermann1-11/+11
Use unsigned variables for storing the count of items or for iteration variables. Since there can never be a negative number of items, it makes sense to use an unsigned data type here. This change is safe because the unsigned values are only used for adddressing array items. git-svn-id: https://svn.musicpd.org/mpd/trunk@7214 09075e82-0dd4-0310-85a5-a0d7c8717e4f
2008-03-26don't repeat select()Max Kellermann1-5/+2
The interfaces main loop repeats the select() (non-blocking) after an event was handled. I do not see any reason for that, since all events should be handled after the first select(). This double select() does nothing than consume more CPU cycles. git-svn-id: https://svn.musicpd.org/mpd/trunk@7213 09075e82-0dd4-0310-85a5-a0d7c8717e4f
2008-03-26unlimited select() timeoutMax Kellermann1-5/+3
mpd sets a 1s select() timeout for no reason. This makes mpd wake up the CPU, consume some cycles just to see there is nothing to do. We can save that by specifying NULL instead of a timeout. git-svn-id: https://svn.musicpd.org/mpd/trunk@7212 09075e82-0dd4-0310-85a5-a0d7c8717e4f
2008-03-26networking: more assertions and cleanups to size_t/unsigned changesEric Wong1-17/+25
Basically, I don't trust myself nor Max to not have bugs in our code when switching over to unsigned types, so I've added more assertions which will hopefully trip and force us to fix these bugs before somebody can exploit them :) Some cleanups for parameter parsing using strtol and error reporting to the user. Also, fix some completely garbled indentation in inputStream_http.c git-svn-id: https://svn.musicpd.org/mpd/trunk@7209 09075e82-0dd4-0310-85a5-a0d7c8717e4f
2008-03-26use size_tMax Kellermann1-24/+24
When dealing with in-memory lengths, the standard type "size_t" should be used. Missing one can be quite dangerous, because an attacker could provoke an integer under-/overflow, which may provide an attack vector. git-svn-id: https://svn.musicpd.org/mpd/trunk@7205 09075e82-0dd4-0310-85a5-a0d7c8717e4f
2008-03-26zero is a valid file descriptorMax Kellermann1-3/+3
Although it may not happen in mpd code, it is perfectly possible for a newly allocated file descriptor to be zero. For theoretical correctness, allow 0. git-svn-id: https://svn.musicpd.org/mpd/trunk@7194 09075e82-0dd4-0310-85a5-a0d7c8717e4f
2008-01-27interface: abort if we expire while processing linesEric Wong1-0/+2
If we keep processing expired interfaces in a loop, we'll eventually close it and get fd < 0, causing assertions to fail. git-svn-id: https://svn.musicpd.org/mpd/trunk@7168 09075e82-0dd4-0310-85a5-a0d7c8717e4f
2008-01-03ioops: make this zero-impact when compiling w/o zeroconf as wellEric Wong1-49/+2
This reduces the text size of the binary slightly when zeroconf support is not built, and keeps the interface code cleaner as well. git-svn-id: https://svn.musicpd.org/mpd/trunk@7133 09075e82-0dd4-0310-85a5-a0d7c8717e4f
2008-01-03zeroconf: reformat (with mpd-indent.sh + manual tweaks)Eric Wong1-7/+7
Also, lower the impact of compiling this w/o zeroconf by making the init/teardown functions static no-ops. Eventually, we should separate the Bonjour and Avahi code into separate files and have callbacks registered for each one, avoiding the #ifdef mess we have now... git-svn-id: https://svn.musicpd.org/mpd/trunk@7132 09075e82-0dd4-0310-85a5-a0d7c8717e4f
2008-01-03Cleanup #includes of standard system headers and put them in one placeEric Wong1-15/+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
2007-09-01interface: fix IPV6 hostname buffer deallocation from automaticsEric Wong1-12/+7
The host buffer that hostname pointed to is no longer on the stack by the time the SECURE() message is printed. So make it static and thus accessible to all. We won't be calling this stuff in the middle of a child process/thread/task, so there's no Also, hostname is a constant string we shouldn't modify, so mark it as const char *. git-svn-id: https://svn.musicpd.org/mpd/trunk@6842 09075e82-0dd4-0310-85a5-a0d7c8717e4f

to segfault. This could be exploited by malicious users to crash other users' mpd. But more importantly, I believe clients are doing this unintentionally, and that this is what is causing mpd to segfault for many people after running for long periods of time. git-svn-id: https://svn.musicpd.org/mpd/trunk@5649 09075e82-0dd4-0310-85a5-a0d7c8717e4f
2007-01-14Don't initialize globals to zero (or NULL)Eric Wong1-6/+6
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 Wong1-3/+3
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
2006-08-18fix a few warnings on 64-bit machinesEric Wong1-2/+2
size_t is bigger than int on most 64-bit machines, so cast size_t to long when passing them to printf-like functions. Ideally we'd use %z, but many compilers don't support it. git-svn-id: https://svn.musicpd.org/mpd/trunk@4656 09075e82-0dd4-0310-85a5-a0d7c8717e4f

2006-07-30fix some warnings introduced in the big malloc-reduction patchEric Wong1-0/+1

2006-07-30interface/connection malloc reductions from mpd-keEric Wong1-175/+270
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
