looks like they're working on it but "The work to make sure mac os compiles rocksdb is not completed yet.": 2158776 also is there a public issue tracker other than this one? |
@mreiferson I'm still working on it :-) |
@liukai good to hear :) If it's at all helpful here is my WIP: https://github.com/mreiferson/rocksdb/commit/906ceafdda7826fddb0321d1e7a43c4dd41de801 |
Rocksdb now works on Mac. Please refer to https://github.com/facebook/rocksdb/blob/master/COMPILATION.md to get more details. |
COMPILATION.md moved to https://github.com/facebook/rocksdb/blob/master/INSTALL.md |
Summary: The way DBImpl::TEST_CompactRange() throttles down the number of bg compactions can cause it to deadlock when CompactRange() is called concurrently from multiple threads. Imagine a following scenario with only two threads (max_background_compactions is 10 and bg_compaction_scheduled_ is initially 0): 1. Thread #1 increments bg_compaction_scheduled_ (to LargeNumber), sets bg_compaction_scheduled_ to 9 (newvalue), schedules the compaction (bg_compaction_scheduled_ is now 10) and waits for it to complete. 2. Thread #2 calls TEST_CompactRange(), increments bg_compaction_scheduled_ (now LargeNumber + 10) and waits on a cv for bg_compaction_scheduled_ to drop to LargeNumber. 3. BG thread completes the first manual compaction, decrements bg_compaction_scheduled_ and wakes up all threads waiting on bg_cv_. Thread #1 runs, increments bg_compaction_scheduled_ by LargeNumber again (now 2*LargeNumber + 9). Since that's more than LargeNumber + newvalue, thread #2 also goes to sleep (waiting on bg_cv_), without resetting bg_compaction_scheduled_. This diff attempts to address the problem by introducing a new counter bg_manual_only_ (when positive, MaybeScheduleFlushOrCompaction() will only schedule manual compactions). Test Plan: I could pretty much consistently reproduce the deadlock with a program that calls CompactRange(nullptr, nullptr) immediately after Write() from multiple threads. This no longer happens with this patch. Tests (make check) pass. Reviewers: dhruba, igor, sdong, haobo Reviewed By: igor CC: leveldb Differential Revision: https://reviews.facebook.net/D14799
Summary: This diff provides the ability to print out a stacktrace when the process receives certain signals. Currently, we enable this for the following signals (program error related): SIGILL SIGSEGV SIGBUS SIGABRT Application simply #include "util/stack_trace.h" and call leveldb::InstallStackTraceHandler() during initialization, if signal handler is needed. It's not done automatically when openning db, because it's the application(process)'s responsibility to install signal handler and some applications might already have their own (like fbcode).

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: The RocksDB correctness testing has recently discovered a possible, but very unlikely, correctness issue with MultiGet. The issue happens when all of the below conditions are met - 1. Duplicate keys in a MultiGet batch 2. Key matches the last key in a non-zero, non-bottommost level file 3. Final value is not in the file (merge operand, not snapshot visible etc) 4. Multiple entries exist for the key in the file spanning more than 1 data block. This can happen due to snapshots, which would force multiple versions of the key in the file, and they may spill over to another data block 5. Lookup attempt in the SST for the first of the duplicates fails with IO error on a data block (NOT the first data block, but the second or subsequent uncached block), but no errors for the other duplicates 6. Value or merge operand for the key is present in the very next level The problem is, in FilePickerMultiGet, when looking up keys in a level we use FileIndexer and the overlapping file in the current level to determine the search bounds for that key in the file list in the next level. If the next level is empty, the search bounds are reset and we do a full binary search in the next non-empty level's LevelFilesBrief. However, under the conditions #1 and #2 listed above, only the first of the duplicates has its next-level search bounds updated, and the remaining duplicates are skipped.

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. Pull Request resolved: #12784 Test Plan: I was able to steadily repro by building with `COMPILE_WITH_ASAN=1` running db_stress. ``` COMPILE_WITH_ASAN=1 make -j64 dbg ``` ``` ./db_stress
