How to set provides/conflicts in PKGBUILD to avoid conflicting package

Mr. Tao · 2020-09-03 09:23:48

I have a version of pulseaudio with AirPlay 2 support in AUR.

I am able to build, install and use this package fine. But on a system update, whenever e.g. Chromium or Firefox, probably any package dependent on libpulse is to be updated, there is a conflict between libpulse and libpulse-airplay:

❯ sudo pacman -S chromium
resolving dependencies...
looking for conflicting packages...
:: libpulse and libpulse-airplay are in conflict. Remove libpulse-airplay? [y/N]

There are provides and conflicts set in the package:

package_libpulse-airplay() {
  provides=('libpulse=13.99.1')
  conflicts=(libpulse)
 ⋮

How do I make libpulse-airplay a proper substitute for libpulse?

What if you modify the PKGBUILD for libpulse-airplay to include the similar line as the official package: https://github.com/archlinux/svntogit-p … BUILD#L121

You can retain the conflicts=

Adding the .so objects to provides does look like a good idea but it won't solve the issue.
(I've been bitten by this same issue in the past)

chromium depends on libpulse, your package provides libpulse=13.99.1 .
pacman dependency logic* concludes your package doesn't satisfy chromium requirements.

Remove the version number from the provides array and just provide libpulse .

*
for pkgver comparisons pacman uses vercmp , no idea if that's also used/suitable for libpulse vs libpulse=13.99.1 type comparisons .

@Lone_Wolf - Agreed, my point was to follow the official PKGBUILD as closely as possible.

provides=('libpulse=13.99.1') means pacman considers that libpulse is installed with a pkgver of 13.99.1, removing the version number *never* makes it more compatible.

chromium doesn't depend on a specific version of libpulse, so this cannot have anything to do with it.

@Mr. Tao,

What's the exact error message if you answer "N" at the prompt? What's the output of pacman -Qi libpulse-airplay?

In the past I’ve had requires without versions. I’ve tried adding version in a (obviously futile) attempt to work around this issue.

sudo pacman -Suuy

Provides        : libpulse.so=0-64  libpulse-simple.so=0-64  libpulse-mainloop-glib.so=0-64

Do you notice how it does not provide libpulse at *all*?

Look more closely at your PKGBUILD, it clearly isn't doing what you think it is doing.

In fact...

  provides=('libpulse=13.99.1')
[...]
  provides=(libpulse{,-simple,-mainloop-glib}.so)

The line comes from the original PKGBUILD. Does it mean that the original package provides libpulse implicitly because of the contents of pkgname array?

I’ve just rebuilt the package with provides you suggested and subsequent upgrade of chromium passed without a complaint! Thank you.

No. Packages don't provide themselves.

"provides" is a list of additional names, on top of the pkgname, which can be used to satisfy dependencies. But that doesn't mean every package needs to

provides = $pkgname

Your problem is completely unrelated. Do you understand why, in bash,

provides=(one)
provides=(two)

completely throws away the first line and never uses it?

Missing dependency on gst-plugins-base-libs. Could you not adjust the patch to apply cleanly without using three way merge?

I’ve added gst-plugins-base-libs dependency.
I think that the original author of the patch would the proper person to make adjustments. I am not familiar with pulseaudio at all.
