This is a pretty huge change that will be important for being able to
handle nested or mutually recursive `dispatch()` and `audioMaster()`
calls. This sadly all had to be done in a single commit, so here's a
summary:
- `src/common/sockets.h:Sockets` contains all sockets on both the plugin
and the Wine host side, and is used to both listen on and connect to
the sockets.
- Sockets and other temporary files respect `$XDG_RUNTIME_DIR` instead
of being dumped in `/tmp`.
- All sockets now have a unique endpoint in
`/run/user/<uid>/yabridge-<plugin_name>-<random_id>/`. This is
important for when we want to have multiple socket connections for
handling `dispatch()` and `audioMaster()`.
- Because of the above, we no longer clean up the socket endpoint files
after the connection gets established during initialization. Instead
we'll remove the socket base directory when shutting down.
As per Boost.Asio's manual, an explicit `socket.shutdown()` is needed
before calling `close()`. For some reason this worked fine in almost
every situation, but when hosting both a plugin hosted within a group
host process and a normal individually hosted plugin within a single
process, and then removing those two plugins in order, the
`host_vst_dispatch` socket of the first plugin never got closed. This
would hang the entire shutdown sequence to hang on the
`dispatch_handler` jthread.
First discovered in #45
I'm still really curious why this double reparent would be needed
though. Everything works fine on any other i3 config I've tried, and
even the exact same config in a VM works fine for me.
I'm not sure how many people use WMs that don't implement
`_NET_ACTIVE_WINDOW`, but at least this will give those people some way
to grab input focus, even if it's not as good as the new method.
These things should not fail (and I've never seen one of these thing
error out with yabridge), but in the case they do an assertion is at
least a lot trace down than a segfault.
This fixes keyboard focus not returning when closing dialogs in Melda
plugins. I'll have to do some more testing to see if this does not
introduce any unwanted side effects.
Boost.Process's `boost::process::environment::at` throws when the
environment variable does not exist, as opposed to `operator[]` which
falls back to an empty value.
Not sure why it's doing this, but Renoise seems to report 112 speakers
per audio channel, so the 256 audio channel limit would be exceeded when
using more than 2 output channels.
This is not ideal since it requires the user to know about this option
and to create a config file, but I think it's the best we can do without
compromising on yabridge's transparency and 'zero hacks' philosophy.
See #29 and #32.
This works around Waves plugins causing an infinite message loop. Since
we run the loop 30 times per second anyways splitting the loop up into
chunks of 20 shouldn't be an issue.
This significantly reduces the latency with no real drawbacks from what
I've noticed. Wineserver is still run using the normal scheduling
policies because from my testing running that with realtime priority
that can actually increase latencies, although doing so will greatly
reduce the variance in processing time.
This sounds like it would the simplest way to work around the issue of
E27 calculating its own coordinates based on the parent window's
coordinates. I have not noticed any weird issues with having this
enabled all the time, but less moving parts is always better so it's
still behind an option.
When creating copies with yabridgectl. This should at least give an
advance warning that some additional steps are required when first
setting up yabridge.
It's a bit clearer this way. I would prefer using jthreads here, but we
would still need this try-catch block since there's no way to cancel
synchronous Boost.Asio socket operations other than closing the socket.
