* Revert "Relax warnings as errors so we can build on Clang 11 (#123)" This reverts commit 710819d. * Rename InternalDBStatsType enum names (facebook#5779) Summary: When building with clang 9, warning is reported for InternalDBStatsType type names shadowed the one for statistics. Rename them. Pull Request resolved: facebook#5779 Test Plan: Build with clang 9 and see it passes. Differential Revision: D17239378 fbshipit-source-id: af28fb42066c738cd1b841f9fe21ab4671dafd18 * Fix compiler error by deleting GetContext default ctor (facebook#5685) Summary: When updating compiler version for MyRocks I'm seeing this error with rocksdb: ``` ome/yzha/mysql/mysql-fork2/rocksdb/table/get_context.h:91:3: error: explicitly defaulted default constructor is implicitly deleted [-Werror,-Wdefaulted-function-deleted] GetContext() = default; ^ /home/yzha/mysql/mysql-fork2/rocksdb/table/get_context.h:166:18: note: default constructor of 'GetContext' is implicitly deleted because field 'tracing_get_id_' of const-qualified type 'const uint64_t' (aka 'const unsigned long') would not be initialized const uint64_t tracing_get_id_; ^ ``` The error itself is rather self explanatory and makes sense. Given that no one seems to be using the default ctor (they shouldn't, anyway), I'm deleting it.
