AnalyzeTemporaryDtors: true
#### Disabled checks and why: #####
#
# -readability-convert-member-functions-to-static,
# This check started going off in the upgrade from clang-tidy-8 to clang-tidy-12. It is not always correct because
# we hide the reference implementation in another repository.
# -clang-analyzer-security.insecureAPI.rand, -clang-analyzer-security.insecureAPI.rand, -bugprone-unhandled-self-assignment,
# -bugprone-implicit-widening-of-multiplication-result
# These have not been investigated yet.
# -bugprone-reserved-identifier,
# Fails due to use of some __SHORT_FILE__ symbol, originating from very old code.
# -bugprone-suspicious-include,
# False positive due to GTest code.
# -bugprone-too-small-loop-variable,
# Complains about uint8_t or uint16_t when the limit on the loop is a container's .size() (size_t).
# We usually do this when we know the maximum size of the container though, so propose leaving disabled.
# -clang-analyzer-cplusplus.NewDelete,
# Seems to generate false positives. Suggest relying on ASAN and valgrind for memory stuff.
# -clang-analyzer-cplusplus.NewDeleteLeaks,
# Seems to generate false positives. Suggest relying on ASAN and valgrind for memory stuff.
# -modernize-use-nodiscard,
# New C++17 feature, slightly polarizing. Would clutter codebase.
# -modernize-avoid-c-arrays,
# Let's not deal with people doing ridiculous things to hack around this. If it bites them, it bites them.
# -bugprone-signed-char-misuse, -clang-diagnostic-implicit-int-float-conversion, -readability-make-member-function-const,
# -readability-qualified-auto, -readability-redundant-access-specifiers
# These were previously disabled for not being available in clang-tidy-8. They are now available on our clang-tidy-12,
# and potentially worth investigating/fixing.
# -bugprone-exception-escape
# Weird. No idea how to resolve.
# -bugprone-branch-clone,
# frequent misidentification
# -google-default-arguments
# Too many virtual functions in pika have default parameters, specifically void Do(std::shared_ptr<Partition> partition = nullptr)
# -clang-analyzer-cplusplus.InnerPointer
# I don't know why this bug in the RocksDB library fails to suppress detection.So I have to disable this check.
#--google-explicit-constructor
# There are so many implicit convert in pika
#--use_of_tag_name_without_tag
# like class member is class , If there is no class tag, an error will be reported
# class A{ B b_; } -> error ; class A{ class B b_; } -> no error ;
#-clang-analyzer-core.CallAndMessage
# pika/src/storage/src/scope_record_lock.h
# Always detect a null pointer and call the TryLock method
# Called C++ object pointer is null [clang-analyzer-core.CallAndMessage,-warnings-as-errors]
# lock_mgr_->UnLock(key);
#-clang-analyzer-deadcode.DeadStores
# error detection in some places
#-google-runtime-int
# todo discussed, because there are so many of `long` and `long long` in pika, so disable for now
#-clang-diagnostic-unused-command-line-argument
# because there are to many compile command error in github ci, but no error in local environment
# See in build folder compile_commands.json
#-clang-diagnostic-ignored-optimization-argument
# The reason disabled this is same as above.
