We don't track insertions and deletions for tables that are merely linked to by tables actually being observed (for performance reasons, since we don't need that information), but the check for that was missing in one place. This would be merely a slowdown rather than a crash, but deletions.add_shifted() can overflow size_t if the passed-in index represents a newly inserted row and the check for that didn't work due to not tracking insertions for the table. The only remotely realistic way to actually have size_t overflow is to have previously cleared the table (the table clear instruction does not include the old size of the table, so it just marks {0, SIZE_T_MAX} as deleted). Fixes #3537. |

Realm Object Store
Cross-platform code used accross bindings. Binding developers can choose to use some or all the included functionality:
object_store
/schema
/object_schema
/property
- contains the structures and logic used to setup and modify realm files and their schema.shared_realm
- wraps the object_store apis to provide transactions, notifications, realm caching, migrations, and other higher level functionality.object_accessor
/results
/list
- accessor classes, object creation/update pipeline, and helpers for creating platform specific property getters and setters.parser
/query_builder
- cross platform query parser and query builder - requires and object_accessor specialization for argument support. Depends on https://github.com/ColinH/PEGTL
Building
The object store's build system currently only suports building for OS X. The object store itself can build for all Apple platforms when integrated into a binding.
-
Install CMake. You can download an installer for OS X from the CMake download page, or install via Homebrew:
brew install cmake
-
Generate build files:
cmake .
-
Build:
make
If you wish to build against a local version of core you can invoke cmake
like so:
cmake -DREALM_CORE_VERSION=/path/to/realm-core
The given core tree will be built as part of the object store build.
Building with Sanitizers
The object store can be built using ASan, TSan and/or UBSan by specifying -DSANITIZE_ADDRESS=1
, -DSANITIZE_THREAD=1
, or -DSANITIZE_UNDEFINED=1
when inoking CMake.
Building with ASan requires specifying a path to core with -DREAM_CORE_VERSION
as core needs to also be built with ASan enabled.
On OS X, the Xcode-provided copy of Clang only comes with ASan, and using TSan or UBSan requires a custom build of Clang.
If you have installed Clang as an external Xcode toolchain (using the install-xcode-toolchain
when building LLVM), note that you'll have to specify -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++
when running cmake
to stop cmake from being too clever.
