Subject: ceph-perf: fix github-check and use run-make.sh for clang-19
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=e23d26bb0f2b8f5d7e539e0a21df88ae1f960262;p=ceph-build.git

ceph-perf: fix github-check and use run-make.sh for clang-19

github-check fails on fresh venvs with PyJWT 2.13+ because github3
passes app_id as int to jwt.encode(). Pin pyjwt<2.13 before installing
githubcheck, and quote app-id/install-id in github-check calls.

Stop probing for clang down to 18 in the perf job; Crimson needs
clang-19. Let run-make.sh install it via llvm.sh (get_llvm) and select
it with discover_compiler, same as make-check nodes.
