We had been disabling -Wdelete-non-virtual-dtor, because this seems to be done intentionally in the generated code of the actor compiler. I spent some time trying to rewrite it in a way that doesn't literally delete/destroy through a pointer to a base class without a virtual destructor, but I was unable to come up with something that passes correctness. My best guess is that we do this so that we can destroy actor state classes, call callbacks registered on the actor SAV, and then destroy the SAV.
Anyway now we'll detect new usages of deleting through a pointer to a base class without a virtual destructor.
I ran this command in my build directory after compiling with
OPEN_FOR_IDE. It took a few small tweaks to get it to compile, which is
outside the scope of this commit.
$ python run-clang-tidy.py -j $(nproc) -checks='-*,performance-inefficient-vector-operation' -fix
Use `clang-tidy -p . $file -checks='-*,modernize-use-override' -header-filter='.*' -fix`
to fix missing overrides, and then use git clang-format to reformat just
those changes. This went pretty well for most files.
Formatting the following files went off the rails, so I'm going to
follow up with a commit that's just clang-tidy and no clang-format.
- fdbclient/DatabaseBackupAgent.actor.cpp
- fdbclient/FileBackupAgent.actor.cpp
- fdbserver/OldTLogServer_4_6.actor.cpp
- fdbmonitor/SimpleIni.h
- fdbserver/workloads/ClientTransactionProfileCorrectness.actor.cpp
So that we can use it from a piece of flow code without breaking module
boundaries.
Also rename generated-constants to crc32c-generated-constants so that
it's more apparent that they're related files.
Fix several such reports from ubsan
E.g.
/Users/anoyes/workspace/foundationdb/flow/Arena.h:794:16: runtime error: null pointer passed as argument 1, which is declared to never be null
