Remove RocksDB LITE (#11147)
Summary: We haven't been actively mantaining RocksDB LITE recently and the size must have been gone up significantly. We are removing the support. Most of changes were done through following comments: unifdef -m -UROCKSDB_LITE `git grep -l ROCKSDB_LITE | egrep '[.](cc|h)'` by Peter Dillinger. Others changes were manually applied to build scripts, CircleCI manifests, ROCKSDB_LITE is used in an expression and file db_stress_test_base.cc.

Support WriteCommit policy with sync_fault_injection=1 (#10624)
Summary:
**Context:**
Prior to this PR, correctness testing with un-sync data loss [disabled](https://github.com/facebook/rocksdb/pull/10605) transaction (`use_txn=1`) thus all of the `txn_write_policy` . This PR improved that by adding support for one policy - WriteCommit (`txn_write_policy=0`).
**Summary:**
They key to this support is (a) handle Mark{Begin, End}Prepare/MarkCommit/MarkRollback in constructing ExpectedState under WriteCommit policy correctly and (b) monitor CI jobs and solve any test incompatibility issue till jobs are stable. (b) will be part of the test plan.
For (a)
- During prepare (i.e, between `MarkBeginPrepare()` and `MarkEndPrepare(xid)`), `ExpectedStateTraceRecordHandler` will buffer all writes by adding all writes to an internal `WriteBatch`.
- On `MarkEndPrepare()`, that `WriteBatch` will be associated with the transaction's `xid`.
- During the commit (i.e, on `MarkCommit(xid)`), `ExpectedStateTraceRecordHandler` will retrieve and iterate the internal `WriteBatch` and finally apply those writes to `ExpectedState`
- During the rollback (i.e, on `MarkRollback(xid)`), `ExpectedStateTraceRecordHandler` will erase the internal `WriteBatch` from the map.
For (b) - one major issue described below:
- TransactionsDB in db stress recovers prepared-but-not-committed txns from the previous crashed run by randomly committing or rolling back it at the start of the current run, see a historical [PR](

move db_stress locking to `StressTest::Test*()` functions (#10678)
Summary: One problem of the previous strategy was `NonBatchedOpsStressTest::TestIngestExternalFile()` could release the lock for `rand_keys[0]` in `rand_column_families[0]`, and then subsequent operations in the same loop iteration (e.g., `TestPut()`) would run without locking. This PR changes the strategy so each `Test*()` function is responsible for acquiring and releasing its own locks.

Fix a bug of CompactionIterator/CompactionFilter using `Delete` (#9929)
Summary: When compaction filter determines that a key should be removed, it updates the internal key's type to `Delete`. If this internal key is preserved in current compaction but seen by a later compaction together with `SingleDelete`, it will cause compaction iterator to return Corruption. To fix the issue, compaction filter should return more information in addition to the intention of removing a key. Therefore, we add a new `kRemoveWithSingleDelete` to `CompactionFilter::Decision`. Seeing `kRemoveWithSingleDelete`, compaction iterator will update the op type of the internal key to `kTypeSingleDelete`. In addition, I updated db_stress_shared_state.[cc|h] so that `no_overwrite_ids_` becomes `const`. It is easier to reason about thread-safety if accessed from multiple threads. This information is passed to `PrepareTxnDBOptions()` when calling from `Open()` so that we can set up the rollback deletion type callback for transactions. Finally, disable compaction filter for multiops_txn because the key removal logic of `DbStressCompactionFilter` does not quite work with `MultiOpsTxnsStressTest`.

Improve stress test for MultiOpsTxnsStressTest (#9829)
Summary: Adds more coverage to `MultiOpsTxnsStressTest` with a focus on write-prepared transactions. 1. Add a hack to manually evict commit cache entries. We currently cannot assign small values to `wp_commit_cache_bits` because it requires a prepared transaction to commit within a certain range of sequence numbers, otherwise it will throw. 2. Add coverage for commit-time-write-batch. If write policy is write-prepared, we need to set `use_only_the_last_commit_time_batch_for_recovery` to true. 3. After each flush/compaction, verify data consistency. This is possible since data size can be small: default numbers of primary/secondary keys are just 1000.

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 |

Stress test for RocksDB transactions (#8936)
Summary: Current db_stress does not cover complex read-write transactions. Therefore, this PR adds coverage for emulated MyRocks-style transactions in `MultiOpsTxnsStressTest`. To achieve this, we need: - Add a new operation type 'customops' so that we can add new complex groups of operations, e.g. transactions involving multiple read-write operations. - Implement three read-write transactions and two read-only ones to emulate MyRocks-style transactions. Pull Request resolved: https://github.com/facebook/rocksdb/pull/8936 Test Plan: ``` make check ./db_stress -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=100000 ``` Next step is to add more configurability and refine input generation and result reporting, which will done in separate follow-up PRs.
