Summary: * Consolidate use of std::regex for testing to testharness.cc, to minimize Facebook linters constantly flagging uses in non-production code. * Improve syntax and error messages for asserting some string matches a regex in tests. * Add a public Regex wrapper class to encapsulate existing usage in ObjectRegistry. * Remove unnecessary include <regex> * Put warnings that use of Regex in production code could cause bad performance or stack overflow. Intended follow-up work: * Replace std::regex with another underlying implementation like RE2 * Improve ObjectRegistry interface in terms of possibly confusing literal string matching vs. regex and in terms of reporting invalid regex. Pull Request resolved: https://github.com/facebook/rocksdb/pull/8740 Test Plan: tests updated, basic unit test for public Regex, and some manual testing of temporary changes to see example error messages: utilities/backupable/backupable_db_test.cc:917: Failure 000010_1162373755_138626.blob (child.name) does not match regex [0-9]+_[0-9]+_[0-9]+[.]blobHAHAHA (pattern) db/db_basic_test.cc:74: Failure R3SHSBA8C4U0CIMV2ZB0 (sid3) does not match regex [0-9A-Z]{20}HAHAHA Reviewed By: mrambacher Differential Revision: D30706246 Pulled By: pdillinger fbshipit-source-id: ba845e8f563ccad39bdb58f44f04e9da8f78c3fd |

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.
Start with example usage here: https://github.com/facebook/rocksdb/tree/main/examples
See the github wiki for more explanation.
The public interface is in include/. Callers should not include or
rely on the details of any other header files in this package. Those
internal APIs may be changed without warning.
Design discussions are conducted in https://www.facebook.com/groups/rocksdb.dev/ and https://rocksdb.slack.com/
