On implementing the 'beep' escape code in conhost

[Barath Rk]

This is in reference to https://bugs.winehq.org/show_bug.cgi?id=50109

Looking at Windows 10, the console 'beep' sound is represented in the
registry under the respective key as a path i.e.
C:\Windows\media\sound.wav. So the implementation should be as simple
as getting the value from this key and calling PlaySound on the
retrieved path.

Is this the expected way to implement the beep?

Also, would it be alright to simply get the .wav files from a Windows
10 install and store them in a windows\media folder when the wine
prefix is created or will there be (legal)issues lifting the .wav
files from Win10?

Beeps are very simple and should probably just be recreated similarly via
one of wine's multimedia libs.

Windows sounds are probably not redistributable which are regardless also
not included with wine for legal purposes hence winetricks.

Search repo for WAV files for tests/examples:

./dlls/dmime/tests/resource.rc:21:/* ffmpeg -f lavfi -i
"sine=frequency=600" -t 0.1 -ar 44100 -f wav -acodec pcm_u8 test.wav */

Code generated sounds are probably better for simplicity vs using more
elaborate sound tools such as LMMS.

Suggested impl seems reasonable otherwise.

MessageBeep shall be used

[Barath Rk]

Using MessageBeep for the implementation works on XWayland, but using
Wayland I don't get the Beep as it is not implemented in the
winewayland driver. How would the workflow look for implementing this?
Would I have to open a separate MR or can I just add the Wayland Beep
implementation as another commit in the same MR as the console Beep
implementation?

both approaches are valid

using 1MR+2commits make clean why you're adding code to wayland driver

but has the drawback of involving several maintainers

[Barath Rk]

Then would it be fine to create 2 MRs at the same time? I was a little
biased towards 1 MR 2 Commits because of the wiki stating that multiple
outstanding MRs from an individual are discouraged.

The same principle applies to one MR encompassing multiple functionalities.

The rule isn't clear cut, and is intended to discourage overflowing
reviewer resources by e.g., making the same mistake across multuple MRs. If
your MRs have distinct maintainers, and you get their approval, then you
should be fine.

Should I have to ping the maintainer beforehand to get their opinion
on opening an MR?

If so, any idea who I am supposed to ping for the Wayland MR? I know
Eric deals with console related stuff but I don't see any entry in the
MAINTAINERS file for the wayland driver maintainer.

Probably simpler for you to get started at this point and ask forgiveness
for minor mistakes rather than permission.

Git history/logs for files touched is often reliable for determining
maintainers if not updated elsewhere yet.

Isn't MessageBeep a higher level API?

higher than what?

(it's supposed to be called from conhost.exe, so I don't see too much 
trouble here)

and I tried to avoid calling kernel32.Beep from conhost (it would 
require calling some MM apis from kernel32, which doesn't seem great either)

Higher than Beep(). I thought that MessageBeep() was supposed to call Beep() in fact.

I guess with conhost maybe it is the other way around.

Well if MessageBeep() might fall back to Beep(), and Beep() calls IOCTL_CONDRV_BEEP, then the latter shouldn't call MessageBeep().

Huh? Beep() calls IOCTL_CONDRV_BEEP, and Eric is proposing that IOCTL_CONDRV_BEEP should call MessageBeep().

[Barath Rk]

Well, I was under the impression that Eric was referring to the part
in write_console that deals with the '\a' case, which was the subject
matter of the bug that I linked at the start as well.

in fact, I did propose MessageBeep to avoid calling Beep from conhost 
(as our current MessageBeep implementation doesn't fallbck to Beep) and 
to make the patch simpler

but I don't have strong objection for playing a predefined sound instead 
directly from conhost

If that is the case, would it be better to first create a proper
implementation of Beep(that doesn't rely on forwarding to conhost. I
suppose this should be possible with whatever winmm provides right now) and
then use that here?

This would also avoid having to implement a beep for the wayland driver. I
guess that it wasn't done at the start because it isn't as straightforward
to implement as it is in X11(where you just call XBell) and while looking
into it, I figured that the simplest way to implement the wayland driver
would be with a previous sound, so we might as well just do that in conhost.

The trouble with that is layering; it's surely wrong to call winmm or anything audio from kernelbase. It may be that it calls out to a service.

Could you explain what you mean by it being a layering issue? the
waveOut* functions of winmm essentially call the respective audio
drivers. By "service" do you mean pulse/ALSA?

If we were to implement Beep without calls to winmm from kernelbase, I
suppose we would have to forward the request like it is already being
done, but to something more agnostic than conhost. How would one go
about this though? I thought of a server request, but I realize server
changes are quite rare.

from an architecture point of view, kernel(base|32) is at a "layer" 
below winmm (and any other sound related DLLs)

so winmm is allowed to call into kernel(base[32), but not the other way 
around

Zeb suggests we have a service responding to a beep ctl command (and 
that service could call into winmm)

yes to decide if we reuse and existing service or add a new one

I have created an MR for this issue. This produces a simple double
beep as the bell.

I haven't added any tests as I was unsure about them.

FWIW, I think that calling IOCTL_CONDRV_BEEP from Beep is not exactly 
right. As the FIXME in Beep says, it should work when no console is 
attached, which means that it should not depend on conhost. If we'd get 
that right, we could use Beep from conhost.
