Summary: In https://github.com/facebook/rocksdb/issues/8539 I accidentally only checked for GCC TSAN, which is what I tested locally, while CircleCI and FB CI use clang TSAN. Related: other existing code like in stack_trace.cc only check for clang TSAN. I've now standardized these to the GCC convention in port/lang.h, so now #ifdef __SANITIZE_THREAD__ can check for any TSAN (assuming lang.h include) Pull Request resolved: https://github.com/facebook/rocksdb/pull/8543 Test Plan: Put an assert(false) in slice_test and look for the NOTE about "signal-unsafe call", both GCC and clang. Eventually, CircleCI TSAN in https://github.com/facebook/rocksdb/issues/8538 Reviewed By: zhichao-cao Differential Revision: D29728483 Pulled By: pdillinger fbshipit-source-id: 8a3b8015c2ed48078214c3ee17146a2c3f11c9f7
RocksDB: A Persistent Key-Value Store for Flash and RAM Storage
RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)
This code is a library that forms the core building block for a fast key-value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it especially suitable for storing multiple terabytes of data in a single database.
