When the physical memory of the process reaches 90% of the mem limit, trigger the load channel mgr to brush down
The default value of be.conf mem_limit is changed from 90% to 80%, and stability is the priority.
Fix deadlock in arena_locks in BufferPool::BufferAllocator::ScavengeBuffers and _lock in DebugString
In pr #8476, all memory usage of a process is recorded in the process mem tracker,
and all memory usage of a query is recorded in the query mem tracker,
and it is still necessary to manually call `transfer to` to track the cached memory size.
We hope to separate out more detailed memory usage based on Hook TCMalloc new/delete + TLS mem tracker.
In this pr, the more detailed mem tracker is switched to TLS, which automatically and accurately
counts more detailed memory usage than before.
* update gcc to gcc 10 and support c++17
update brpc to 0.9.7
update boost to 1.73
remove third-party boost 1.54 for mysql
* update cmake version
* ignore jdk version
* remove unused patch
* avoid use SYS_getrandom call
* Reduce UT binary size
Almost every module depend on ExecEnv, and ExecEnv contains all
singleton, which make UT binary contains all object files.
This patch seperate ExecEnv's initial and destory to anthor file to
avoid other file's dependence. And status.cc include debug_util.h which
depend tuple.h tuple_row.h, and I move get_stack_trace() to
stack_util.cpp to reduce status.cc's dependence.
I add USE_RTTI=1 to build rocksdb to avoid linking librocksdb.a
