It would be great for paru to support the --rebuildtree option. This is important for libraries which need to be rebuilt with dependent .so changes.

@Morganamilo I was about to port over this feature and was wondering if you have any suggestions on how to do this before I get into it?

One question I had was do I piggy back off rebuild like what we did for the rebuildall feature? Or do I create another flag for rebuildtree specifically?

Also I'm not sure how to get the recursive dependencies for a package to modify the following line:

https://github.com/Morganamilo/paru/blob/c122ce076906f0e6c138f07add559490d6fd6ebd/src/install.rs#L1956

There's checks to stop resolving deps if a package is satisfied. There needs to be a condition that says not to stop resolving if rebuild tree is set and the package is an aur package.

[acxz]

So something else like this?

 if (config.rebuild == YesNoTreeAll::Yes && base.target()) || (config.rebuild == YesNoTreeAll::Tree && base.{missing_func()}) || config.rebuild == YesNoTreeAll::All { 

Is there already a function that can check if the aur package is a recursive dep or does that function need to be created? If so, where would it reside?

Sorry for pestering, just a bit of a noob.

[Morganamilo]

You can't check that. This needs to be a check at the solver level that tells it to not stop.

[acxz]

By the solver level do you mean resolve_targets? https://github.com/Morganamilo/paru/blob/c122ce076906f0e6c138f07add559490d6fd6ebd/src/install.rs#L846

[Morganamilo]

The resolver is its own library https://github.com/Morganamilo/aur-depends

[acxz]

I see I'll go ahead and open an issue in that repo as well.

Okay so building on top of the linked PR:

Would I just simply add a flag here based on some user rebuildtree flag?

https://github.com/Morganamilo/paru/blob/c122ce076906f0e6c138f07add559490d6fd6ebd/src/resolver.rs#L12

[Morganamilo]

Implemented, though this doesn't work if you're using local repos. Due to them being repo packages. This will probably be fixed at a later date.

[acxz]

Thanks for this! Should I open another issue for --rebuild=tree for repo packages? Or should we just reopen this one?

Also should documentation be added for --rebuild to incorporate the tree option?
