There were a few macOS related bug reports on the bug tracker which
have been open for years without a volunteer caring for them. The
GitHub actions build has also been broken for a long time due to bugs
in the ancient LLVM toolchain shipped with macOS, making macOS an
unsuitable non-Linux target for testing MPD's portability.
All of this makes macOS support an annoying liability for me. To
avoid more frustration, I'm hereby dropping macOS support completely
from MPD. Maybe this causes enough pain for a new maintainer to
spawn, but maybe nobody cares, so... let's see.
Build dep on pkconf is not explicitly needed because other dependencies
pull pkconf indirectly (ie libid3tag0-dev), but explicit declaration of
a direct MPD build dep is better IMHO.
Most of the Android specific meson code has been removed and replaced with
the grade build system.
The new meson build scripts build and move the libmpd.so binaries into the correct
location that gradle expects. After than gradle handles building the rest of the Android app.
Icons and banners have been updated for the modern app packaging expectations.
For reference here was the figma template Google provides that I used to back the png versions
for older versions of Android <https://www.figma.com/community/file/1283953738855070149>
Add an `always_off` option to outputs that causes them to never start
playback even if they're enabled.
This allows placeholder `null` outputs to be defined for the purpose
of having an external client react to the enabled state without the
side effects of real outputs. Like an external mixer, the client can
perform some action when an output is enabled.
Normally `null` outputs can be used for playback so it's possible for
MPD to continue playback silently if a problem occurs with all the real
outputs (or there are none enabled).
Boost makes building a piece of software much more difficult than
necessary. It's a huge library, and just uncompressing it takes a
considerable amount of time. MPD only used a tiny fraction of it, yet
its header bloat made the MPD build very slow. Locating Boost was
difficult due to its arcane build system and its resistance to use
pkg-config; it's always a special case. MPD could never use features
of newer Boost versions because Linux distributions always shipped old
Boost versions. Boost made everything complicated and slow.
So, finally, after getting rid of GLib (commit ccdb94b06c), switching
to C++ and using Boost (commit 0801b3f495), we've finally get rid of
it 8 years later.
Unfortunately, I had to reimplement parts of it along the way
(e.g. IntrusiveList). Kind of NIH, but on the other hand, compiling
MPD has become much easier for users.
The writing and reading of metadata involves lots of different programs
and libraries. Therefore it is prudent to point out how exactly MPD
receives metadata. Ideally this helps to point users to the right place
if their tags are not picked up correctly.
NB: Check the sysconfdir setting to determine where mpd will look for mpd.conf; if you expect mpd to look for /etc/mpd.conf the sysconfdir must be '/etc' (i.e., not 'etc' which will result in mpd looking for /usr/local/etc/mpd.conf):
.. code-block:: none
meson configure output/release |grep sysconfdir
If this is not /etc (or another path you wish to specify):
.. code-block:: none
$ meson configure output/release -Dsysconfdir='/etc' ; meson configure output/release |grep syscon
sysconfdir /etc Sysconf data directory
