* [clangd] Move clangd tests to clangd directory. check-clangd is no longer ↵Sam McCall2019-04-291-219/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | part of check-clang-tools. Summary: Motivation: - this layout is a pain to work with - without a common root, it's painful to express things like "disable clangd" (D61122) - CMake/lit configs are a maintenance hazard, and the more the one-off hacks for various tools are entangled, the more we see apathy and non-ownership. This attempts to use the bare-minimum configuration needed (while still supporting the difficult cases: windows, standalone clang build, dynamic libs). In particular the lit.cfg.py and lit.site.cfg.py.in are merged into lit.cfg.in. The logic in these files is now minimal. (Much of clang-tools-extra's lit configs can probably be cleaned up by reusing lit.llvm.llvm_config.use_clang(), and every llvm project does its own version of LDPATH mangling. I haven't attempted to fix any of those). Docs are still in clang-tools-extra/docs, I don't have any plans to touch those.

* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636
* [clangd] Fix a crash when reading an empty index file.Haojian Wu2019-01-081-0/+4
| | | | | | | | | | | | | | | Summary: Unfortunately, yaml::Input::setCurrentDocument() and yaml::Input::nextDocument() are internal APIs, the way we use them may cause a nullptr accessing when processing an empty YAML file.

* [clangd] Remove 'using namespace llvm' from .cpp files. NFCIlya Biryukov2019-01-071-3/+2
| | | | | | | | The new guideline is to qualify with 'llvm::' explicitly both in '.h' and '.cpp' files. This simplifies moving the code between header and source files and is easier to keep consistent. llvm-svn: 350531

* [clangd] Put direct headers into srcs section.Kadir Cetinkaya2018-11-271-17/+30
| | | | | | | | | | | | | | | | | | | Summary: Currently, there's no way of knowing about header files using compilation database, since it doesn't contain header files as entries. Using this information, restoring from cache using compile commands becomes possible instead of doing directory traversal. Also, we can issue indexing actions for out-of-date headers even if source files depending on them haven't changed.

* [clangd] Truncate SymbolID to 8 bytes.Haojian Wu2018-11-161-8/+8
| | | | | | | | | | | | | | Summary: This is our goal. It has a non-zero rick, but so far we haven't see any collision (externally and internally).

* [clangd] Replace StringRef in SymbolLocation with a char pointer.Haojian Wu2018-11-141-3/+4
| | | | | | | | | | | | | | | | | Summary: This would save us 8 bytes per ref, and buy us ~40MB in total for llvm index (from ~300MB to ~260 MB). The char pointer must be null-terminated, and llvm::StringSaver guarantees it.

* [clangd] Truncate SymbolID to 16 bytes.Sam McCall2018-10-241-14/+13
| | | | | | | | | | | | | | | Summary: The goal is 8 bytes, which has a nonzero risk of collisions with huge indexes. This patch should shake out any issues with truncation at all, we can lower further later.

* [clangd] Namespace style cleanup in cpp files. NFC.Sam McCall2018-10-201-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Standardize on the most common namespace setup in our *.cpp files: using namespace llvm; namespace clang { namespace clangd { void foo(StringRef) { ... } And remove redundant llvm:: qualifiers. (Except for cases like make_unique where this causes problems with std:: and ADL). This choice is pretty arbitrary, but some broad consistency is nice. This is going to conflict with everything. Sorry :-/ Squash the other configurations: A) using namespace llvm; using namespace clang; using namespace clangd; void clangd::foo(StringRef); This is in some of the older files. (It prevents accidentally defining a new function instead of one in the header file, for what that's worth). B) namespace clang { namespace clangd { void foo(llvm::StringRef) { ... } This is fine, but in practice the using directive often gets added over time. C) namespace clang { namespace clangd { using namespace llvm; // inside the namespace This was pretty common, but is a bit misleading: name lookup preferrs clang::clangd::foo > clang::foo > llvm:: foo (no matter where the using directive is). llvm-svn: 344850

* [clangd] Merge binary + YAML serialization behind a (mostly) common interface.Sam McCall2018-09-251-30/+28
| | | | | | | | | | | | | | | | | Summary: Interface is in one file, implementation in two as they have little in common. A couple of ad-hoc YAML functions left exposed: - symbol -> YAML I expect to keep for tools like dexp - YAML -> symbol is used for the MR-style indexer, I think we can eliminate this (merge-on-the-fly, else use a different serialization) Reviewers: kbobyrev Subscribers: mgorny, ilya-biryukov, ioeric, MaskRay, jkorous, arphaman, kadircet, cfe-commits Differential Revision: https://reviews.llvm.org/D52453 llvm-svn: 342999

* [clangd] Define a compact binary serialization fomat for symbol slab/index.Sam McCall2018-09-041-0/+138
Summary: This is intended to replace the current YAML format for general use. It's ~10x more compact than YAML, and ~40% more compact than gzipped YAML: llvmidx.riff = 20M, llvmidx.yaml = 272M, llvmidx.yaml.gz = 32M It's also simpler/faster to read and write. The format is a RIFF container (chunks of (type, size, data)) with: - a compressed string table - simple binary encoding of symbols (with varints for compactness) It can be extended to include occurrences, Dex posting lists, etc. There's no rich backwards-compatibility scheme, but a version number is included so we can detect incompatible files and do ad-hoc back-compat. Alternatives considered: - compressed YAML or JSON: bulky and slow to load - llvm bitstream: confusing model and libraries are hard to use. My attempt produced slightly larger files, and the code was longer and slower. - protobuf or similar: would be really nice (esp for back-compat) but the dependency is a big hassle - ad-hoc binary format without a container: it seems clear we're going to add posting lists and occurrences here, and that they will benefit from sharing a string table. The container makes it easy to debug these pieces in isolation, and make them optional.
