On my system, equery d only reiterates that it is only required with USE=pulseaudio. | Code: | $ equery d apulse
* These packages depend on apulse:
www-client/firefox-115.15.0 (pulseaudio ? >=media-sound/apulse-0.1.12-r4[sdk])
(pulseaudio ? >=media-sound/apulse-0.1.12-r4[sdk])
x11-misc/i3status-2.14-r1 (pulseaudio ? media-sound/apulse[sdk])
(pulseaudio ? media-sound/apulse[sdk]) |
I'll have to try uninstalling at some point to see if libpulse is brought in.
The ebuild only suggests either is required if USE=pulseaudio: | Code: | pulseaudio? (
|| (
media-libs/libpulse
>=media-sound/apulse-0.1.12-r4[sdk]
)
) |
| Code: | use pulseaudio && myaudiobackends+="pulseaudio,"
! use pulseaudio && myaudiobackends+="alsa," |

So either apulse or libpulse is still required, correct? What's the difference? I have apulse installed, but emerge says I can remove it because nothing depends on it. I use firefox esr from source, and libpulse is not installed. | emerge -cav apulse: | >>> These are the packages that would be unmerged:
media-sound/apulse

|
Required with USE="pulseaudio", yes, one or the other.
I suppose the main difference will be dependencies, and indeed, if both are installed, apulse is used over libpulse.

Thanks. With "pulesaudio" seems to be the key. I probably misunderstood some post a long time ago. I'll try removing it and see what happens.

These are all more or less various forms of the same outcome for logic on dependency. Which is why I'm forced to dig into the actual ebuild to [strike]sanity check[/strike] confirm, again.
| Code: |
COMMON_DEPEND="${FF_ONLY_DEPEND}
...
pulseaudio? (
|| (
media-libs/libpulse
>=media-sound/apulse-0.1.12-r4[sdk]
)
)
|
I read that as a || bash OR short circuit logic test, if left hand side not true, continue (it may be POSIX compliant too, irrelevant to deeper discussion and don't care). If -pulseaudio (which you'd usually expect to see ref'ed as !pulseaudio), then it goes off requiring the other two. |
That's not correct. pulseaudio? is a boolean test which if satisfied will trigger an evaluation of an OR expression between those two, which means if libpulse is available, it shortcircuits, if it's not, it looks for apule and if that's not available it returns false which then causes portage to throw an error at you.
This is not POSIX or Bash, this is Boolean logic which has no varieties.
Also equery will not give you accurate information. It takes shortcuts and you need to further examine the information it's given to you. It only sees there is such a dependency but does not go further to check whether it actually takes place.
You should further run equery u firefox-bin or emerge -pv firefox-bin to check if it actually takes place.
