Summary: We need to turn on -Wshorten-64-to-32 for mobile. See D1671432 (internal phabricator) for details. This diff turns on the warning flag and fixes all the errors. There were also some interesting errors that I might call bugs, especially in plain table. Going forward, I think it makes sense to have this flag turned on and be very very careful when converting 64-bit to 32-bit variables. Test Plan: compiles Reviewers: ljin, rven, yhchiang, sdong Reviewed By: yhchiang Subscribers: bobbaldwin, dhruba, leveldb Differential Revision: https://reviews.facebook.net/D28689 |

This folder defines a REDIS-style interface for Rocksdb. Right now it is written as a simple tag-on in the rocksdb::RedisLists class. It implements Redis Lists, and supports only the "non-blocking operations". Internally, the set of lists are stored in a rocksdb database, mapping keys to values. Each "value" is the list itself, storing a sequence of "elements". Each element is stored as a 32-bit-integer, followed by a sequence of bytes. The 32-bit-integer represents the length of the element (that is, the number of bytes that follow). And then that many bytes follow. NOTE: This README file may be old. See the actual redis_lists.cc file for definitive details on the implementation. There should be a header at the top of that file, explaining a bit of the implementation details.
