namespace ROCKSDB_NAMESPACE {
// This file defines MultiOpsTxnsStress so that we can stress test RocksDB
// transactions on a simple, emulated relational table.
//
// The record format is similar to the example found at
// https://github.com/facebook/mysql-5.6/wiki/MyRocks-record-format.
//
// The table is created by
// ```
// create table t1 (
// a int primary key,
// b int,
// c int,
// key(c),
// )
// ```
//
// (For simplicity, we use uint32_t for int here.)
//
// For this table, there is a primary index using `a`, as well as a secondary
// index using `c` and `a`.
//
// Primary key format:
// | index id | M(a) |
// Primary index value:
// | b | c |
// M(a) represents the big-endian format of a.
//
// Secondary key format:
// | index id | M(c) | M(a) |
// Secondary index value:
// | crc32 |
// Similarly to M(a), M(c) is the big-endian format of c.
//
// The in-memory representation of a record is defined in class
// MultiOpsTxnsStress:Record that includes a number of helper methods to
// encode/decode primary index keys, primary index values, secondary index keys,
// secondary index values, etc.
//
// Sometimes primary index and secondary index reside on different column
// families, but sometimes they colocate in the same column family. Current
// implementation puts them in the same (default) column family, and this is
// subject to future change if we find it interesting to test the other case.
//
// Class MultiOpsTxnsStressTest has the following transactions for testing.
//
// 1. Primary key update
// UPDATE t1 SET a = 3 WHERE a = 2;
// ```
// tx->GetForUpdate(primary key a=2)
// tx->GetForUpdate(primary key a=3)
// tx->Delete(primary key a=2)
// tx->Put(primary key a=3, value)
// tx->batch->SingleDelete(secondary key a=2)
// tx->batch->Put(secondary key a=3, value)
// tx->Prepare()
// Tx->Commit()
// ```
//
// 2. Secondary key update
// UPDATE t1 SET c = 3 WHERE c = 2;
// ```
// iter->Seek(secondary key)
// // Get corresponding primary key value(s) from iterator
// tx->GetForUpdate(primary key)
// tx->Put(primary key, value c=3)
// tx->batch->SingleDelete(secondary key c=2)
// tx->batch->Put(secondary key c=3)
// tx->Prepare()
// tx->Commit()
// ```
//
// 3. Primary index value update
// UPDATE t1 SET b = b + 1 WHERE a = 2;
// ```
// tx->GetForUpdate(primary key a=2)
// tx->Put(primary key a=2, value b=b+1)
// tx->Prepare()
// tx->Commit()
// ```
//
// 4. Point lookup
// SELECT * FROM t1 WHERE a = 3;
// ```
// tx->Get(primary key a=3)
// tx->Commit()
// ```
//
// 5. Range scan
// SELECT * FROM t1 WHERE c = 2;
// ```
// it = tx->GetIterator()
// it->Seek(secondary key c=2)
// tx->Commit()
// ```

Improve stress test for transactions (#9568) Summary: Test only, no change to functionality. Extremely low risk of library regression. Update test key generation by maintaining existing and non-existing keys. Update db_crashtest.py to drive multiops_txn stress test for both write-committed and write-prepared. Add a make target 'blackbox_crash_test_with_multiops_txn'. Running the following commands caught the bug exposed in https://github.com/facebook/rocksdb/issues/9571. ``` $rm -rf /tmp/rocksdbtest/* $./db_stress -progress_reports=0 -test_multi_ops_txns -use_txn -clear_column_family_one_in=0 \ -column_families=1 -writepercent=0 -delpercent=0 -delrangepercent=0 -customopspercent=60 \ -readpercent=20 -prefixpercent=0 -iterpercent=20 -reopen=0 -ops_per_thread=1000 -ub_a=10000 \ -ub_c=100 -destroy_db_initially=0 -key_spaces_path=/dev/shm/key_spaces_desc -threads=32 -read_fault_one_in=0 $./db_stress -progress_reports=0 -test_multi_ops_txns -use_txn -clear_column_family_one_in=0 -column_families=1 -writepercent=0 -delpercent=0 -delrangepercent=0 -customopspercent=60 -readpercent=20 \ -prefixpercent=0 -iterpercent=20 -reopen=0 -ops_per_thread=1000 -ub_a=10000 -ub_c=100 -destroy_db_initially=0 \ -key_spaces_path=/dev/shm/key_spaces_desc -threads=32 -read_fault_one_in=0 ``` Running the following command caught a bug which will be fixed in https://github.com/facebook/rocksdb/issues/9648 . ``` $TEST_TMPDIR=/dev/shm make blackbox_crash_test_with_multiops_wc_txn ``` Pull Request resolved: https://github.com/facebook/rocksdb/pull/9568 Reviewed By: jay-zhuang Differential Revision: D34308154 Pulled By: riversand963 fbshipit-source-id: 99ff1b65c19b46c471d2f2d3b47adcd342a1b9e7
