Fix sanitizers suppressions The -fsanitize-ignorelist (-fsanitize-blacklist is the alias for it) accepts not the suppressions but special case list, that accept only `fun` and `src`, so convert tsan_suppressions.txt into a proper tsan_ignorelist.txt with a proper syntax, otherwise suppressions simply does not work [1].

Fix suppressions for rd_avg_calc()/rd_avg_rollover() (due to static qualifier) The problem is that TSan still fails [1] is that ignorelist does not work for static functions without asterisk: // test.cpp #include <thread> bool flag = false; // avoid mangling extern "C" { static void set_flag_impl() { flag = true; } void set_flag() { set_flag_impl(); } void set_flag_if() { if (flag) flag = false; } } int main() { std::thread t1([]{ set_flag(); }); std::thread t2([]{ set_flag_if(); }); t1.join(); t2.join(); return 0; } // ignorelist [thread] fun:set_flag_impl $ clang++ -g -fno-omit-frame-pointer -fsanitize=thread -fsanitize-ignorelist=ignorelist -o test test.cpp && ./test SUMMARY: ThreadSanitizer: data race /tmp/test-tsan-ignorelist/test.cpp:19:9 in set_flag_if $ sed -i 's/set_flag_impl/*set_flag_impl*/' ignorelist $ clang++ -g -fno-omit-frame-pointer -fsanitize=thread -fsanitize-ignorelist=ignorelist -o test test.cpp && ./test OK But, note that ignorelist is tricky, and will not work for functions with __always_inline__ attribute for example. P.S. set_flag_impl also has brackets in the output (i.e. set_flag_impl()), while ther eis brackets for rd_avg_calc on CI [1].

Fix possible data-race StorageKafka with statistics_interval_ms>0 The problem here is that ignorelist did not work by some reason, if I will look at the ignored functions it should not contain any TSan interseption code, while it does: $ lldb-13 clickhouse (lldb) target create "clickhouse" disas -n rd_avg_rollover Current executable set to '/home/azat/ch/tmp/tsan-test/clickhouse' (x86_64).
