Casting a pointer to some sort of integer and formatting it into a
string isn't valid. A pointer derived from this hex string won't work
reliably. Since ffmpeg doesn't provide a nice API for passing our
pointer, we have to think of a different hack: ffmpeg passes the exact
URL pointer to mpdurl_open(), and we can make this string part of a
struct. This reduces the problem to casting the string back to the
struct.
This is still a workaround, but this is "sort of portable", unless the
ffmpeg people start messing with the URL pointer (which would be valid
according to the API definition).

Since ffmpeg svn r12865, you have to include libavcodec/avcodec.h
instead of avcodec.h. This cannot be checked at compile time, instead
we have to add a check to configure.ac. Viliam's original ffmpeg
plugin was based on the newer ffmpeg library, while my Debian
installation had the older version. My attempt to correct his include
statements wasn't correct after all.

{song,dir}vec_for_each each failed to gracefully handle deleted
files when iterating through. While we were thread-safe, we
were not safe within the calling thread. If a callback we
passed caused sv->nr to shring, our index would still increment;
causing files to stay in the database.
A way to test this is to remove 10 or so contiguous songs from a
>10 song directory.
|
|
Like the songvec nr_lock, only one lock is used for all
traversals since they're rarely changed. This only
projects traversals, but not the individual structures
themselves.
|
|
We definitely don't modify them here.
|
|
This will make it easier to introduce locking
|
|
There was only one user of pathcpy_trunc(), which can be eliminated.
|
|
Again, GLib's version is more robust than ours.
|
|
GLib's g_path_get_basename() is much more reliable than
mpd_basename(). The latter could be tricked into an assertion
failure.
|
|
Identifiers with two leading underscores are reserved for the C
compiler's internal use. Don't use them in the source.
|
|
Due to an off-by-one bug in map_fs_to_utf8(), the function returned
database paths with a leading slash.
|
|
The macro name is HAVE_STRUCT_UCRED, not HAVE_UCRED.
|
|
The typedefs aren't using by anybody but struct input_stream. Remove
them and declare the method type within struct input_stream.
|
|
The mpdurl_* code is internal, don't expose them. Also don't
initialize struct members with NULL.
|
|
client->permission is a bit set, and should be unsigned.
|
|
Reduce two temporary variables to only one.
|
|
There is no sense in using the kernel's send buffer size (SO_SNDBUF)
for MPD's send buffer. Convert it into a static buffer of 4 kB.
|
|
Use a literal in the struct declaration, and sizeof(client->buffer)
everywhere else. Also shrink the buffer from 40 kB to 4 kB. The
buffer must only be large enough to hold one line of input, and 4 kB
is still more than enough.
|
|
The buffer pointers must not exceed the buffer size.
|
|
Use ssize_t instead of int.
|
|
Commit 6eb62e47 didn't obey partial lines correctly: when a line
wasn't finished in one read, the first part was ignored when the rest
arrived.
|
|
[mk: fixed indent, changed copyright statement, added autoconf test,
fixed includes paths, fixed 2 gcc warnings, don't close input stream
twice]
|
|
Don't compile the sources of disabled decoder plugins at all, and
don't attempt to register these.
|
|
If a feature is disabled, don't compile the source file at all,
disable it completely in Makefile.am instead.
|
|
The nmemb argument isn't actually useful, and one of nmemb and size
was always passed as 1. Remove it.
|
|
Provide a struct type which can be forward-declared. The typedef
InputStream is deprecated now.
|
|
Wake up the player as soon as the decoder thread has entered its loop.
This fixes a dead lock when the input is blocking.
|
|
When adding a local file, clients have to use the "file" URI schema
described in RFC 1738 3.10. By adding this schema to "urlhandlers", a
client can detect whether this feature is available.
|
|
The local variable "passcred" was only used by ucred code.
|
|
By default, glibc 2.8 hides struct ucred behind the _GNU_SOURCE
macro. I don't want to enable that globally, because it may encourage
the use of non-portable functions. Test if "struct ucred" is
available, and enable _GNU_SOURCE if required.
For details about that issue, see glib's bug database:
http://sources.redhat.com/bugzilla/show_bug.cgi?id=6545
|
|
Detect the following libraries with pkg-config: libshout, libid3tag,
libmad.
|
|
The undocumented command "add /" adds the full music database to the
playlist. Don't interpret this special path as a local file path.
|
|
Allow a local user to not only add his own files, but also all
world-readable files (mode 0444).
|
|
Don't load non-regular files.
|
|
Clients which have authenticated via unix socket may add local files
to the MPD playlist, provided that they own the file.
|
|
Returning the playlist_result value from a command handler does not
make sense. Call print_playlist_result() there, and forward its
return value.
|
|
Replace some complicated checks from addToPlaylist() to the simpler
function song_by_url().
|
|
Some functions assume that a song is not in the database when it is a
remote song. Based on that, they decide whether they are responsible
for freeing the song struct. Add a special function which checks
whether a song is in the database (currently equal to song_is_file()).
|
|
Enable authentication over unix sockets. Store the client's uid in
the client struct.
|
|
Skip only the special directory entries "." and "..", don't skip all
other "hidden" files.
|
|
The switch from ogg.m4 to pkg-config intentionally disabled
libvorbisenc. Enable it when shout_ogg is used.
|
|
This patch fixes several imports to use pkg-config instead of certain
esoteric tests.
|
|
string_toupper() and strDupToUpper() were not able to deal with
character sets other than US-ASCII. Use GLib's g_utf8_casefold()
for strings.
|
|
Moved the musicDir variable and its initialization code from path.c to
mapper.c.
|
|
When the music directory is not mounted yet, let MPD start anyway.
|
|
GLib provides an easier API for character set conversion than iconv().
Use g_convert() / g_convert_with_fallback() for all character
conversions. We should optimize the path.h API later to return a
newly allocated buffer, so we can just pass GLib's return value.
|
|
GLib is a nice and portable utility library. We are going to use it
from now on, and eliminate a lot of duplicated code from MPD. Why
invent the wheel again and again?
|
|
Indentation was broken in tag_id3.c: it used 4 spaces instead of tabs.
|
|
|
|
Use memchr() instead of manually traversing the input buffer. Update
the client's properties after all commands have been processed. Check
for buffer overflow once.
