Thanks, already fixed.

…ocks. Summary: SizeBeingCompacted was called without any lock protection. This causes crashes, especially when running db_bench with value_size=128K. The fix is to compute SizeUnderCompaction while holding the mutex and passing in these values into the call to Finalize.

`GetOptionsFromString()` is included in `set_options_one_in` because its current behavior actually involves invoking `PrepareOptions()` on existing shared option objects that may be in-use by a DB. While this has known problems like facebook#10374, it is actually used in production and users are finding these problems before us. To prevent accidental coasting we should turn on the feature in stress/crash test to ensure we discover these problems before our users do. Test Plan: - Build with TSAN: `$ COMPILE_WITH_TSAN=1 make -j24 db_stress` - Repro some `GenericRateLimiter` race conditions: ``` $ ./db_stress -rate_limiter_bytes_per_sec=1048576 --set_options_one_in=100 --max_key=1000000 ...

…tionSecondaryCache` and add `CompressedSecondaryCache` into stress tests. (#10523) Summary: 1. Fix the memory leak in db_stress tests that are caused by `FaultInjectionSecondaryCache`. To address the test requirements for both CompressedSecondaryCache and CachlibWrapper, a new class variable `base_is_compressed_sec_cache_` is added to determine the different behaviors in `Lookup()` and `WaitAll()`. 2. Add `CompressedSecondaryCache` into stress tests. Before this PR, memory leak is reported during crash tests if `CompressedSecondaryCache` is in stress tests. One example is shown as follows: ``` ==70722==ERROR: LeakSanitizer: detected memory leaks Direct leak of 6648240 byte(s) in 83103 object(s) allocated from: #0 0x13de9d7 in operator new(unsigned long)

Summary: **Context:** ajkr's command revealed an existing TSAN data race between `TestFSWritableFile::Append` and `TestFSWritableFile::Sync` on `TestFSWritableFile::state_` ``` $ make clean && COMPILE_WITH_TSAN=1 make -j56 db_stress $ python3 tools/db_crashtest.py blackbox --simple --duration=3600 --interval=10 --sync_fault_injection=1 --disable_wal=0 --max_key=10000 --checkpoint_one_in=1000 ``` The race is due to concurrent access from [checkpoint's WAL sync](https://github.com/facebook/rocksdb/blob/7.4.fb/utilities/fault_injection_fs.cc#L324) and [db put's WAL write when ‘sync_fault_injection=1 ‘](https://github.com/facebook/rocksdb/blob/7.4.fb/utilities/fault_injection_fs.cc#L208) to the `state_` on the same WAL `TestFSWritableFile` under the missing synchronization. ``` WARNING: ThreadSanitizer: data race (pid=11275) Write of size 8 at 0x7b480003d850 by thread T23 (mutexes: write M69230): #0

The current threadpool design expects that host/client programs that use RocksDB will explicitly call ThreadPoolImpl::Impl::JoinThreads before the threadpool destructor is called. It has been observed that a case may arise in which the join on the threads is not done and the destructor is called by the exit handler of the host program. When this happens, the threadpool destructor will hang on the call to pthread_cond_destroy as show in the truncated stack trace of a hung process below: $ pstack 3885 #0 0x000014e2288ebe63 in pthread_cond_destroy@@GLIBC_2.3.2 () from target:/lib64/libpthread.so.0 facebook#1 0x000014e225a969af in rocksdb::ThreadPoolImpl::Impl::~Impl (this=0x14e227c472a0, __in_chrg=<optimized out>) at MariaDB/storage/rocksdb/rocksdb/util/threadpool_imp.cc:147 facebook#2 std::default_delete<rocksdb::ThreadPoolImpl::Impl>::operator() (this=<optimized out>, __ptr=0x14e227c472a0) at /gcc-x.5.0/include/c++/x.5.0/bits/unique_ptr.h:78 facebook#3 std::unique_ptr<rocksdb::ThreadPoolImpl::Impl, std::default_delete<rocksdb::ThreadPoolImpl::Impl> >::~unique_ptr (this=<optimized out>, __in_chrg=<optimized out>) at /gcc-x.5.0/include/c++/x.5.0/bits/unique_ptr.h:263 facebook#4 rocksdb::ThreadPoolImpl::~ThreadPoolImpl (this=<optimized out>, __in_chrg=<optimized out>) at MariaDB/storage/rocksdb/rocksdb/util/threadpool_imp.cc:427 facebook#5 0x000014e225af7186 in std::_Destroy<rocksdb::ThreadPoolImpl> (__pointer=<optimized out>) at /gcc-x.5.0/include/c++/x.5.0/bits/stl_construct.h:98 facebook#6 std::_Destroy_aux<false>::__destroy<rocksdb::ThreadPoolImpl*> (__last=<optimized out>, __first=0x14e227c0f190) at /gcc-x.5.0/include/c++/x.5.0/bits/stl_construct.h:108 facebook#7 std::_Destroy<rocksdb::ThreadPoolImpl*> (__last=<optimized out>, __first=<optimized out>) at /gcc-x.5.0/include/c++/x.5.0/bits/stl_construct.h:137 facebook#8 std::_Destroy<rocksdb::ThreadPoolImpl*, rocksdb::ThreadPoolImpl> (__last=0x14e227c0f1c0, __first=<optimized out>) at /gcc-x.5.0/include/c++/x.5.0/bits/stl_construct.h:206 facebook#9 std::vector<rocksdb::ThreadPoolImpl, std::allocator<rocksdb::ThreadPoolImpl> >::~vector (this=0x14e225f65a40 <rocksdb::Env::Default()::default_env+32>, __in_chrg=<optimized out>) at /gcc-x.5.0/include/c++/x.5.0/bits/stl_vector.h:434 facebook#10 rocksdb::(anonymous namespace)::PosixEnv::~PosixEnv (this=0x14e225f65a20 <rocksdb::Env::Default()::default_env>, __in_chrg=<optimized out>) at MariaDB/storage/rocksdb/rocksdb/env/env_posix.cc:133 facebook#11 0x000014e2285685ac in __run_exit_handlers () from target:/lib64/libc.so.6 facebook#12 0x000014e2285685fa in exit () from target:/lib64/libc.so.6 ... The reason this hang occurs is because the threadpool condition variable may still be locked by other threads. To fix the issue, a cleanup of the threads is forced by calling join before the threadpool proceeds with the rest of it's object destruction process. In this way, we handle any corner cases were the destructor is called, but the threadpool's condition variable is still locked by another thread. Lastly in our call to ThreadPoolImpl::Impl::JoinThreads we set the boolean wait_for_jobs_to_complete = false so that the effect of destructing the threadpool is immediate. This change was tested by using MariaDB as a host program, and making it follow an execution path that directly calls the threadpool destructor as MariaDB is exiting: 1) Remove the addr2line binary on the host machine. This will make the MariaDB cleanup handler to directly call the RocksDB threadpool destructor when a MariaDB crash is instigated. 2) Instigate a crash of MariaDB by sending signal 11 to its running process `pkill -11 mysqld`. 3) Check that MariaDB is no longer running: `ps -ef | grep mysqld`. Before this change, the process would still be in existence in a hang state due to the RocksDB threadpool, but after the change the process properly exits.

Summary: #11872 causes a unit test to start failing with the error message below. The cause is that the additional call to `FlushAllColumnFamilies()` in `DBImpl::ResumeImpl()` can run while DB is closing. More detailed explanation: there are two places where we call `ResumeImpl()`: 1. in `ErrorHandler::RecoverFromBGError`, for manual resume or recovery from errors like OutOfSpace through sst file manager, and 2. in `Errorhandler::RecoverFromRetryableBGIOError`, for error recovery from errors like flush failure due to retryable IOError. This is tracked by `ErrorHandler::recovery_thread_`. Here is how DB close waits for error recovery: https://github.com/facebook/rocksdb/blob/49da91ec097b4efcd8a8e4dc1b287e9f81eb4093/db/db_impl/db_impl.cc#L540-L543 `CancelErrorRecovery()` waits until `recovery_thread_` finishes and `IsRecoveryInProgress()` checks the `recovery_in_prog_` flag. The additional call to `FlushAllColumnFamilies()` in `ResumeImpl()` happens after it clears bg error and the `recovery_in_prog_` flag: https://github.com/facebook/rocksdb/blob/49da91ec097b4efcd8a8e4dc1b287e9f81eb4093/db/db_impl/db_impl.cc#L436-L463. So if `ResumeImpl()` is called in `RecoverFromBGError()`, we can have a thread running `FlushAllColumnFamilies()` while DB is closing and thought that recovery is done. The fix is to only do the additional call to `FlushAllColumnFamilies()` when doing error recovery through `Errorhandler::RecoverFromRetryableBGIOError` by setting flags in `DBRecoverContext`. Pull Request resolved: #11880 Test Plan: `gtest-parallel --repeat=100 --workers=4 ./error_handler_fs_test --gtest_filter="*AutoRecoverFlushError*"` reproduces the error pretty reliably. ```[==========] Running 1 test from 1 test case.

* Rollback other pending memtable flushes when a flush fails (#11865) Summary: when atomic_flush=false, there are certain cases where we try to install memtable results with already deleted SST files. This can happen when the following sequence events happen: ``` Start Flush0 for memtable M0 to SST0 Start Flush1 for memtable M1 to SST1 Flush 1 returns OK, but don't install to MANIFEST and let whoever flushes M0 to take care of it Flush0 finishes with a retryable IOError, it rollbacks M0, (incorrectly) does not rollback M1, and deletes SST0 and SST1 Starts Flush2 for M0, it does not pick up M1 since it thought M1 is flushed Flush2 writes SST2 and finishes OK, tries to install SST2 and SST1 Error opening SST1 since it's already deleted with an error message like the following: IO error: No such file or directory: While open a file for random read: /tmp/rocksdbtest-501/db_flush_test_3577_4230653031040984171/000011.sst: No such file or directory ``` This happens since: 1. We currently only rollback the memtables that we are flushing in a flush job when atomic_flush=false. 2. Pending output SSTs from previous flushes are deleted since a pending file number is released whenever a flush job is finished no matter of flush status: https://github.com/facebook/rocksdb/blob/f42e70bf561d4be9b6bbe7316d1c2c0c8a3818e6/db/db_impl/db_impl_compaction_flush.cc#L3161 This PR fixes the issue by rollback these pending flushes. There is another issue where if a new flush for new memtable starts and finishes after Flush0 finishes. Its output may also be deleted (see more in unit test). It is fixed by checking bg error status before installing a memtable result, and rollback if there is an error. There is a more efficient fix where we just don't release the pending file output number for flushes that delegate installation. It is more efficient since it does not have to rewrite the flush output file. With the fix in this PR, we can end up with a giant file if a lot of memtables are being flushed together. However, the more efficient fix is a bit more complicated to implement (requires associating such pending file numbers with flush job/memtables) and is more risky since it changes normal flush code path.

If the flush for older memtables failed, auto-recovery starts a resume thread which can becomes stuck waiting for all background work to finish (including the flush for younger memtables). If a non-recovery flush starts now and tries to flush, it can make the situation worse since it will fail due to background error but never rollback its memtable: https://github.com/facebook/rocksdb/blob/269478ee4618283cd6d710fdfea9687157a259c1/db/db_impl/db_impl_compaction_flush.cc#L725 This prevents any future flush to pick old memtables. A more detailed repro is in unit test. This PR fixes this issue by 1. Ensure we rollback memtables if an atomic flush fails due to background error 2. When there is a background error, abort atomic flushes that are waiting for older memtables to be installed 3. Do not schedule non-recovery flushes when there is a background error that stops background work There was another issue with atomic_flush=true where DB can hang during DB close, see more in #11867. The fix in this PR, specifically fix 2 above, should be enough to resolve it too. Pull Request resolved: #11872 Test Plan: new unit test.

The cause is that the additional call to `FlushAllColumnFamilies()` in `DBImpl::ResumeImpl()` can run while DB is closing. More detailed explanation: there are two places where we call `ResumeImpl()`: 1. in `ErrorHandler::RecoverFromBGError`, for manual resume or recovery from errors like OutOfSpace through sst file manager, and 2. in `Errorhandler::RecoverFromRetryableBGIOError`, for error recovery from errors like flush failure due to retryable IOError. This is tracked by `ErrorHandler::recovery_thread_`. Here is how DB close waits for error recovery: https://github.com/facebook/rocksdb/blob/49da91ec097b4efcd8a8e4dc1b287e9f81eb4093/db/db_impl/db_impl.cc#L540-L543 `CancelErrorRecovery()` waits until `recovery_thread_` finishes and `IsRecoveryInProgress()` checks the `recovery_in_prog_` flag. The additional call to `FlushAllColumnFamilies()` in `ResumeImpl()` happens after it clears bg error and the `recovery_in_prog_` flag: https://github.com/facebook/rocksdb/blob/49da91ec097b4efcd8a8e4dc1b287e9f81eb4093/db/db_impl/db_impl.cc#L436-L463. So if `ResumeImpl()` is called in `RecoverFromBGError()`, we can have a thread running `FlushAllColumnFamilies()` while DB is closing and thought that recovery is done. The fix is to only do the additional call to `FlushAllColumnFamilies()` when doing error recovery through `Errorhandler::RecoverFromRetryableBGIOError` by setting flags in `DBRecoverContext`.

Summary: # Summary When changing the direction of the multi-cf-iter, we do this by `Seek(current_key)` (if changing from backward to forward) or `SeekForPrev(current_key)` (if forward -> backward) in the child iters and rebuild the heap. `Slice target` is just a pointer and contents are not guaranteed to be the same after re-init the heap.
