I don't like that in some cases we have a unique_ptr and later (ATSUnit) we use a shared_ptr<>. It leaves an author unable to know given some arbitrary DiagnosticOptions* what the lifetime and/or ownership rules are.
There was a problem hiding this comment.
I don't think I understand. Now that DiagnosticOptions are not intrusively reference-counted, raw pointers have clearer semantics than before (typically nullable non-owning borrow), no? I'd also argue that using values, references, raw pointers, unique_ptr and shared_ptr depending on the context is the clearest way to communicate lifetimes and ownership. Regardless, there's only one raw pointer to DiagnosticOptions remaining after my patch in clang::tooling::ToolInvocation, and that has exactly the semantics you'd expect: optional borrow where the owner is someone else and you expect them to keep the object alive long enough.
There was a problem hiding this comment.
@jansvoboda11 the problem is that now an author does not know if a given DiagnosticOption is a unique_ptr or a shared_ptr. A given DiagnosticOption* may or may not be protectable, etc depending on the context and origin of the object.
Philosophically I prefer intrusive refcounts over shared_ptr because to me they make the lifetime much clearer as the lifetime rules are embedded in the type, but I don't think that's an issue in this PR.
My understanding is that the goal of this PR is to say "For API purposes, a given DiagnosticOption reference is only live as long as the API object that vends it. As an implementation detail there are some cases where it can outlast the vending object, but that's not generally part of the user visible API."
That's a perfectly reasonable change, but my concern is that by mixing and matching shared and unique_ptr an author loses the ability to reason about what a given object's lifetime is. It seems like the reason for shared_ptr is to deal with some slightly gross bits of the API, and I wonder if it's possible to fix those APIs so we can just use unique_ptr everywhere?

The
DiagnosticOptionsclass is currently intrusively reference-counted, which makes reasoning about its lifetime very difficult in some cases. For example,CompilerInvocationowns theDiagnosticOptionsinstance (wrapped inllvm::IntrusiveRefCntPtr) and only exposes an accessor returningDiagnosticOptions &. One would think this givesCompilerInvocationexclusive ownership of the object, but that's not the case:This is a perfectly valid pattern that is being actually used in the codebase.
I would like to ensure the ownership of
DiagnosticOptionsbyCompilerInvocationis guaranteed to be exclusive. This can be leveraged for a copy-on-write optimization later on. This PR changes usages ofDiagnosticOptionsacrossclang,clang-tools-extraandlldbto not be intrusively reference-counted.
