tang-jianfeng	08809f5e6c	Implement trace sampling (#4963) ... Summary: Implement trace sampling to allow user to specify the sampling frequency, i.e. save one per how many requests, so that a user does not need to log all if he/she is interested in only a sampled set.

Zhichao Cao	7125e24619	Add the max trace file size limitation option to Tracing (#4610) ... Summary: If user do not end the trace manually, the tracing will continue which can potential use up all the storage space and cause problem. In this PR, the max trace file size is added to the TraceOptions and user can set the value if they need or the default is 64GB.

Soli	f1837595a3	FIX #3278: Move global const object definitions from .h to .cc (#4691) ... Summary: Summary We should declare constants in headers and define them in source files. But this commit is only aimed at compound types. I don't know if it is necessary to do the same thing to fundamental types. I used this command to find all of the constant definitions in header files. `find . -name "*.h" | xargs grep -e "^const .*=.*"` And here is what I found: ``` ./db/version_edit.h:const uint64_t kFileNumberMask = 0x3FFFFFFFFFFFFFFF; ./include/rocksdb/env.h:const size_t kDefaultPageSize = 4 * 1024; ./include/rocksdb/statistics.h:const std::vector<std::pair<Tickers, std::string>> TickersNameMap = { ./include/rocksdb/statistics.h:const std::vector<std::pair<Histograms, std::string>> HistogramsNameMap = { ./include/rocksdb/table.h:const uint32_t kPlainTableVariableLength = 0; ./include/rocksdb/utilities/transaction_db.h:const uint32_t kInitialMaxDeadlocks = 5; ./port/port_posix.h:const uint32_t kMaxUint32 = std::numeric_limits<uint32_t>::max(); ./port/port_posix.h:const int kMaxInt32 = std::numeric_limits<int32_t>::max(); ./port/port_posix.h:const uint64_t kMaxUint64 = std::numeric_limits<uint64_t>::max(); ./port/port_posix.h:const int64_t kMaxInt64 = std::numeric_limits<int64_t>::max(); ./port/port_posix.h:const size_t kMaxSizet = std::numeric_limits<size_t>::max(); ./port/win/port_win.h:const uint32_t kMaxUint32 = UINT32_MAX; ./port/win/port_win.h:const int kMaxInt32 = INT32_MAX; ./port/win/port_win.h:const int64_t kMaxInt64 = INT64_MAX; ./port/win/port_win.h:const uint64_t kMaxUint64 = UINT64_MAX; ./port/win/port_win.h:const size_t kMaxSizet = UINT64_MAX; ./port/win/port_win.h:const size_t kMaxSizet = UINT_MAX; ./port/win/port_win.h:const uint32_t kMaxUint32 = std::numeric_limits<uint32_t>::max(); ./port/win/port_win.h:const int kMaxInt32 = std::numeric_limits<int>::max(); ./port/win/port_win.h:const uint64_t kMaxUint64 = std::numeric_limits<uint64_t>::max(); ./port/win/port_win.h:const int64_t kMaxInt64 = std::numeric_limits<int64_t>::max(); ./port/win/port_win.h:const size_t kMaxSizet = std::numeric_limits<size_t>::max(); ./port/win/port_win.h:const bool kLittleEndian = true; ./table/cuckoo_table_factory.h:const uint32_t kCuckooMurmurSeedMultiplier = 816922183; ./table/data_block_hash_index.h:const uint8_t kNoEntry = 255; ./table/data_block_hash_index.h:const uint8_t kCollision = 254; ./table/data_block_hash_index.h:const uint8_t kMaxRestartSupportedByHashIndex = 253; ./table/data_block_hash_index.h:const size_t kMaxBlockSizeSupportedByHashIndex = 1u << 16; ./table/data_block_hash_index.h:const double kDefaultUtilRatio = 0.75; ./table/filter_block.h:const uint64_t kNotValid = ULLONG_MAX; ./table/format.h:const int kMagicNumberLengthByte = 8; ./third-party/fbson/FbsonJsonParser.h:const char* const kJsonDelim = " ,]}\t\r\n"; ./third-party/fbson/FbsonJsonParser.h:const char* const kWhiteSpace = " \t\n\r"; ./third-party/gtest-1.7.0/fused-src/gtest/gtest.h:const BiggestInt kMaxBiggestInt = ./third-party/gtest-1.7.0/fused-src/gtest/gtest.h:const char kDeathTestStyleFlag[] = "death_test_style"; ./third-party/gtest-1.7.0/fused-src/gtest/gtest.h:const char kDeathTestUseFork[] = "death_test_use_fork"; ./third-party/gtest-1.7.0/fused-src/gtest/gtest.h:const char kInternalRunDeathTestFlag[] = "internal_run_death_test"; ./third-party/gtest-1.7.0/fused-src/gtest/gtest.h:const char* pets[] = {"cat", "dog"}; ./third-party/gtest-1.7.0/fused-src/gtest/gtest.h:const size_t kProtobufOneLinerMaxLength = 50; ./third-party/gtest-1.7.0/fused-src/gtest/gtest.h:const int kMaxStackTraceDepth = 100; ./third-party/gtest-1.7.0/fused-src/gtest/gtest.h:const T* WithParamInterface<T>::parameter_ = NULL; ./util/coding.h:const unsigned int kMaxVarint64Length = 10; ./util/filename.h:const size_t kFormatFileNumberBufSize = 38; ./util/testutil.h:const SliceTransform* RandomSliceTransform(Random* rnd, int pre_defined = -1); ./util/trace_replay.h:const std::string kTraceMagic = "feedcafedeadbeef"; ./util/trace_replay.h:const unsigned int kTraceTimestampSize = 8; ./util/trace_replay.h:const unsigned int kTraceTypeSize = 1; ./util/trace_replay.h:const unsigned int kTracePayloadLengthSize = 4; ./util/trace_replay.h:const unsigned int kTraceMetadataSize = ./utilities/cassandra/serialize.h:const int64_t kCharMask = 0xFFLL; ./utilities/cassandra/serialize.h:const int32_t kBitsPerByte = 8; ``` And these 3 lines are related to this commit: ``` ./include/rocksdb/statistics.h:const std::vector<std::pair<Tickers, std::string>> TickersNameMap = { ./include/rocksdb/statistics.h:const std::vector<std::pair<Histograms, std::string>> HistogramsNameMap = { ./util/trace_replay.h:const std::string kTraceMagic = "feedcafedeadbeef"; ``` Any comments would be appreciated.

Sagar Vemuri	dc3528077a	Update all unique/shared_ptr instances to be qualified with namespace std (#4638) ... Summary: Ran the following commands to recursively change all the files under RocksDB: ``` find . -type f -name "*.cc" -exec sed -i 's/ unique_ptr/ std::unique_ptr/g' {} + find . -type f -name "*.cc" -exec sed -i 's/<unique_ptr/<std::unique_ptr/g' {} + find . -type f -name "*.cc" -exec sed -i 's/ shared_ptr/ std::shared_ptr/g' {} + find . -type f -name "*.cc" -exec sed -i 's/<shared_ptr/<std::shared_ptr/g' {} + ``` Running `make format` updated some formatting on the files touched.

Zhichao Cao	6d75319d95	Add tracing function of Seek() and SeekForPrev() to trace_replay (#4228) ... Summary: In the current trace_and replay, Get an WriteBatch are traced. This pull request track down the Seek() and SeekForPrev() to the trace file. <target_key, timestamp, column_family_id> are write to the file. Replay of Iterator is not supported in the current implementation. Tested with trace_analyzer.

Sagar Vemuri	12b6cdeed3	Trace and Replay for RocksDB (#3837) ... Summary: A framework for tracing and replaying RocksDB operations. A binary trace file is created by capturing the DB operations, and it can be replayed back at the same rate using db_bench. - Column-families are supported - Multi-threaded tracing is supported. - TraceReader and TraceWriter are exposed to the user, so that tracing to various destinations can be enabled (say, to other messaging/logging services). By default, a FileTraceReader and FileTraceWriter are implemented to capture to a file and replay from it. - This is not yet ideal to be enabled in production due to large performance overhead, but it can be safely tried out in a shadow setup, say, for analyzing RocksDB operations. Currently supported DB operations: - Writes: -- Put -- Merge -- Delete -- SingleDelete -- DeleteRange -- Write - Reads: -- Get (point lookups) Pull Request resolved: https://github.com/facebook/rocksdb/pull/3837 Differential Revision: D7974837 Pulled By: sagar0 fbshipit-source-id: 8ec65aaf336504bc1f6ed0feae67f6ed5ef97a72	6 years ago
