Yueh-Hsuan Chiang 74b100ac17 RocksDB Options file format and its serialization / deserialization. ... Summary: This patch defines the format of RocksDB options file, which follows the INI file format, and implements functions for its serialization and deserialization. An example RocksDB options file can be found in examples/rocksdb_option_file_example.ini. A typical RocksDB options file has three sections, which are Version, DBOptions, and more than one CFOptions. The RocksDB options file in general follows the basic INI file format with the following extensions / modifications: * Escaped characters We escaped the following characters: - \n -- line feed - new line - \r -- carriage return - \\ -- backslash \ - \: -- colon symbol : - \# -- hash tag # * Comments We support # style comments. Comments can appear at the ending part of a line. * Statements A statement is of the form option_name = value. Each statement contains a '=', where extra white-spaces are supported. However, we don't support multi-lined statement. Furthermore, each line can only contain at most one statement. * Section Sections are of the form [SecitonTitle "SectionArgument"], where section argument is optional. * List We use colon-separated string to represent a list. For instance, n1:n2:n3:n4 is a list containing four values. Below is an example of a RocksDB options file: [Version] rocksdb_version=4.0.0 options_file_version=1.0 [DBOptions] max_open_files=12345 max_background_flushes=301 [CFOptions "default"] [CFOptions "the second column family"] [CFOptions "the third column family"] Test Plan: Added many tests in options_test.cc Reviewers: igor, IslamAbdelRahman, sdong, anthony Reviewed By: anthony Subscribers: maykov, dhruba, leveldb Differential Revision: https://reviews.facebook.net/D46059		9 years ago
