Maybe you were still seeing diagnostics from the older versions of the files?
clangd should **eventually** produce the right diagnostics, but if processing
of some of the requests is in-flight at the time there results may still be
reported.
BTW, I don't know if you've seen it before, but there's `-input-mirror-file`
option to clangd that records the lsp input which can be used to rerun clangd
later.
# This should be run by VSCode (or Theia)
clangd -input-mirror-file=/tmp/clangd.input
# Later we can rerun from command line
$ clangd < /tmp/clangd.input
# Pass the flag to execute everyhing on one thread
$ clangd -run-synchronously < /tmp/clangd.input
This is useful to debug/rerun and see the logs, etc.
This patch is good to go after remove `std::future<>` from
`reparseOpenedFiles`, unless @malaperle discovers there are other problems.
Ideally, it'd be also nice to have a test for it.
================
Comment at: clangd/ClangdServer.cpp:541
+std::vector<std::future<void>>
+ClangdServer::reparseOpenedFiles() {
----------------
We're not returning futures from `forceReparse` anymore, this function has to
be updated accordingly.
