Summary: The new behaviors introduced by this patch: o When include collection is enabled, we always set IncludeHeader field in Symbol even if it's the same as FileURI in decl. o Disable include collection in FileIndex which is currently only used to build dynamic index. We should revisit when we actually want to use FileIndex to global index. o Code-completion only uses IncludeHeader to insert headers but not FileURI in CanonicalDeclaration. This ensures that inserted headers are always canonicalized. Note that include insertion can still be triggered for symbols that are already included if they are merged from dynamic index and static index, but we would only use includes that are already canonicalized (e.g. from static index). Reason for change: Collecting header includes in dynamic index enables inserting includes for headers that are not indexed but opened in the editor. Comparing to inserting includes for symbols in global/static index, this is nice-to-have but would probably require non-trivial amount of work to get right. For example: o Currently it's not easy to fully support CanonicalIncludes in dynamic index, given the way we run dynamic index. o It's also harder to reason about the correctness of include canonicalization for dynamic index (i.e. symbols in the current file/TU) than static index where symbols are collected offline and sanity check is possible before shipping to production. o We have less control/flexibility over symbol info in the dynamic index (e.g. URIs, path normalization), which could be used to help make decision when inserting includes. As header collection (especially canonicalization) is relatively new, and enabling it for dynamic index would immediately affect current users with only dynamic index support, I propose we disable it for dynamic index for now to avoid compromising other hot features like code completion and only support it for static index where include insertion would likely to bring more value.

//===----------------------------------------------------------------------===// // Clang Tools repository //===----------------------------------------------------------------------===// Welcome to the repository of extra Clang Tools. This repository holds tools that are developed as part of the LLVM compiler infrastructure project and the Clang frontend. These tools are kept in a separate "extra" repository to allow lighter weight checkouts of the core Clang codebase. This repository is only intended to be checked out inside of a full LLVM+Clang tree, and in the 'tools/extra' subdirectory of the Clang checkout. All discussion regarding Clang, Clang-based tools, and code in this repository should be held using the standard Clang mailing lists: http://lists.llvm.org/mailman/listinfo/cfe-dev Code review for this tree should take place on the standard Clang patch and commit lists: http://lists.llvm.org/mailman/listinfo/cfe-commits If you find a bug in these tools, please file it in the LLVM bug tracker: http://llvm.org/bugs/
