clang-tools-extra's Issues

clangd-indexer does not honour directory setting in compile_commands.json

I hope it is ok to raise this issue here - I couldn't find anywhere else other than the mailing list.

I've tried clangd-indexer for a project which has a common compile_commands.json but is built using many different Makefiles in different directories using plain 'make'.

What I have found is running:
clangd-indexer -executor=all-TUs compile_commands.json > clangd.dex

results in many compilation errors due to header files not being found, despite them being in the current directory for the corresponding .cc file. The compile_commands.json specifies the absolute directory which contains both .cc and .h files for each .cc file in question.

Is it possible clangd-indexer is not changing directories to the directory specified in compile_commands.json when trying to compile the TU?

Index storage lacks error handling

If any I/O error occurs, the client has no way to know, etc.

Open Workspace Symbol: searching by wildcard

I should be able to search with *Index, for example and it would give ClangdIndex, etc.

Investigage memory mapping the index storage

Performance and memory usage could be better. It could simplify the code too. We need to understand fully the consequences.

Open Workspace Symbol: searching by qualified name

Only qualified names is possible for now. Have a BTree of qualified names?

Support multiple symbol kinds for the same USRs

What to do when there are such clashes?

Open Workspace Symbol: case insensitive

Right now it's case sensitive. It probably shouldn't be.

Make it possible to abort visiting the BTree

for example, it a query wants max 100 result, it should be possible to stop visiting the BTree and save this precious time.

Open Workspace Symbol: Show declarations when no definition

Declarations should be shown where there is no definition. For example, headers of libraries without source code in the workspace.

Track file content hash while indexing

...to prevent re-indexing generated files on restart, etc.

Index storage should use VFS

So that tests can create files in more appropriate locations.

Open Definition: Ctrl+click on a definition should go to declaration

Right now it jumps to itself, which is pretty useless.

Using logging/tracing facility instead of llvm:errs

Document/publish index performance

Provide comparison with others like Eclipse CDT.

Multithreaded indexing

So that it's faster!
