Well, thanks for reporting this, this seems like a really bad bug, and we'd like to get it fixed on the release branch ASAP. (Just to check - also no compile_flags.txt or other compilation database markers?) Our best guess is this is a fairly long-standing bug in OverlayCDB: the storage location would be ".cache/clangd/index" relative to the *working* directory in some cases. If this theory is correct: - you'd be using an editor/plugin that sends compile commands over LSP (such as YCM + ycm_extra_conf). What are you using? - there should be relatively few *.idx files inside the extra directories (the ones not near your compilation database), corresponding to files you've had open rather than the whole project - we don't know why this wouldn't also have been happenening with the old `.clangd` directories - possible they were there but masked by `.gitignore`? If this doesn't sound likely, it'd be really useful (as we haven't reproduced this) to add a log line if you can, and capture a log. Immediately below the llvm::sys::path::append that was changed in this patch, if you could add: log("BackgroundIndexStorage: File={0} SourceRoot={1} StorageDir={2}", File, PI->SourceRoot, StorageDir); Then delete all the `.cache` directories, open clangd and open files until they come back, and grab the clangd stderr log (editors/plugins expose this in some way). This should give us something to go on, else we'll have to keep guessing...
