Strange items at namespace scope

[oblitum]

The last release doesn't present this issue, but master does. Just after std:: I'm getting all items looking like constructors:

After one more char, it's back to normal:

I cannot reproduce with releases.llvm.org clang 6.0.1 + latest coc.nvim

Actually I think this might be an issue some days ago (completion items were not sorted, thus non-deterministic), but master doesn't have that problem.

Well sad, I cannot reproduce with clang 7.0.1 + ccls 0.20181111.1 + latest ccls.nvim either, but with clang 7.0.1 + ccls master (pacman -S ccls-git) + latest ccls.nvim it's consistent, in my machine at least.

Notice, I didn't use the "std::" namespace completion suggestion, I typed each char, to see result after inserting final :.

I also tried releases.llvm.org clang 7.0.0 + latest coc.nvim but cannot reproduce.

I type s t d : : on an empty line but cannot observe what you saw.

Can you dump the textDocument/completion results (especially the isIncomplete property)?

@MaskRay before I send you that, please try this first. I noticed the issue doesn't happen without my .ccls, with it, it happens:

%clang
-Wall
-Wextra
%c -std=gnu11
%cpp -pedantic
%cpp -std=c++17

If I remove the %cpp -std=c++17 flag I get more usual results, with it I get those strange ones.

Thanks! This is important. I think these (...) completion items are deduction guides that are represented as FunctionTemplate internally. I'll look into it.

The 0.20181111.1 release does not report these because the items: CompletionItem are truncated and they happen to not be included. The 2018-11-23 commit 544610c made the result deterministic but also exposed the issue.

Nice fixed.
