Did we change to clang-tidy 9.0 before we changed to clang 9.0? What's going on here?

For a few hours, yeah
https://bugzilla.mozilla.org/show_bug.cgi?id=1583138#c3 landed "Tue, 24 Sep 2019 21:52:37""
https://bugzilla.mozilla.org/show_bug.cgi?id=1573211#c4 landed "Wed, 25 Sep 2019 21:56:53 "

But here, libclang-cpp.so.9 is a new lib, maybe not installed?

[Andi [:andi]]

maybe we don’t have to strip it when we build the clang-tidy package.

[Andi [:andi]]

Yep, this is a regression caused by bug 1573211.

Attachment: Bug 1584175 - Add lib/libclang-cpp.* to the clang-tidy artifact. r=sylvestre

Since we've upgraded to clang 9, clang-format changed and now uses dynamic libraries
for the clang tooling lib that it uses.

I'd been curious to know the size increase from not (almost) completely removing lib/.

FWIW the first commit did not change any versions. It just made the clang-tidy checkers be ready for either version.

I am getting this error in MacOS
Error determining the version clang-tidy/format binary, please see the attached exception:
dyld: Library not loaded: @rpath/libclang-cpp.dylib
Referenced from: /Users/tnguyen/.mozbuild/clang-tools/clang-tidy/bin/clang-format

I guess that is related to this bug?
