The updated logic for the APK dependencies and provides is as follows:
- If ABI version is defined:
- package is named `package_name-ABI_version`
- package implicitly provides
`package_name-ABI_version=package_version`
this implies that only one version of a package per ABI can be
installed at the same time
- additionally provide `package_name` so multiple packages can be
looked up by its base name
- for each `provides`, provide `provide-ABI_version=package_version`
this implies that only one version of a provide can be installed at
the same time
- else if ABI version is _not_ defined
- package is named `package_name`
- package implicitly provides `package_name=package_version`
this implies that only one version of a package can be installed at
the same time
- if `alternatives` is defined
- for each `provides`, provide `provide`
this implies that multiple versions of a provide can be installed
at the same time
- else if `alternatives` is _not_ defined
- for each `provides`, provide `provide=package_version`
this implies that only one version of a provide can be installed
at the same time
Both cases a package can be looked up by its base name.
ABI version `alternatives`, `conffiles`, `conffiles_static`, `list` and
`rusers` files so multiple versions of the same ABI package can be
installed side by side, and so they don't overwrite each other's
packaging files.
ABI version `EXTRA_DEPENDS` so dependencies can be correctly looked up
using the existing OpenWrt semantics without the ABI specified. This is
needed since ABI-versioned libraries no longer provide
`package_name=package_version`, so that they can be installed side by
side.
Remove duplicate dependencies when `EXTRA_DEPENDS` specifies a versioned
one that is already in `DEPENDS`.
ABI is defined
------------------------------------------------------------------------
`libsqlite3` has `PROVIDES` set to `libfake` and has two different ABI
versions installed. `libfake` is just an example to demonstrate the
mechanics, as the library can already be depended upon using e.g.
`libsqlite3-0=3.51.0-r1`. Note the ABI-versioned lists.
```
root@OpenWrt:/tmp# apk add --allow-untrusted ./libsqlite3-0-3.51.0-r1.apk

```
ABI is not defined
------------------------------------------------------------------------
Both `avahi-dbus-daemon` and `avahi-nodbus-daemon` provide `avahi-daemon`,
but have no ABI specified. This results in `avahi-daemon=0.8-r11` provides
for both packages and only one being able to be installed at the same time:
```

```
Provides and alternatives
------------------------------------------------------------------------
Both `uclient-fetch` and `wget-nossl` provide `wget` and specify
alternatives, so provides are not versioned and both packages can be
installed at the same time:
```
root@OpenWrt:/tmp# apk query --fields name,version,contents,provides uclient-fetch wget-nossl
