We make all MemTrackers shared, in order to show MemTracker real-time consumptions on the web.
As follows:
1. nearly all MemTracker raw ptr -> shared_ptr
2. Use CreateTracker() to create new MemTracker(in order to add itself to its parent)
3. RowBatch & MemPool still use raw ptrs of MemTracker, it's easy to ensure RowBatch & MemPool destructor exec
before MemTracker's destructor. So we don't change these code.
4. MemTracker can use RuntimeProfile's counter to calc consumption. So RuntimeProfile's counter need to be shared
too. We add a shared counter pool to store the shared counter, don't change other counters of RuntimeProfile.
Note that, this PR doesn't change the MemTracker tree structure. So there still have some orphan trackers, e.g. RowBlockV2's MemTracker. If you find some shared MemTrackers are little memory consumption & too time-consuming, you could make them be the orphan, then it's fine to use the raw ptr.
Mainly change:
1. Fix the bug in `update_status(status)` of `PlanFragmentExecutor`.
2. When the FE Coordinator executes `execRemoteFragmentAsync()`, if it finds an RPC error, return a Future with an error code instead of exception.
3. Protect the `_status` in RuntimeState with lock
4. Move the `_runtime_profile` of RuntimeState before the `_obj_pool`, so that the profile will be
deconstructed after the object pool.
5. Remove the unused `ObjectPool` param in RuntimeProfile constructor. If I don't remove it,
RuntimeProfile will depends on the `_obj_pool` in RuntimeProfile.
Remove unused LLVM related codes of directory (step 4):be/src/runtime (#2910)
there are many LLVM related codes in code base, but these codes are not really used.
The higher version of GCC is not compatible with the LLVM 3.4.2 version currently used by Doris.
The PR delete all LLVM related code of directory: be/src/runtime
