Erich Keane	49842aacd9	managed_vector: maybe_constructed ctor to non-constexpr ... Clang enforces that a union's constexpr CTOR must initialize one of the members. The spec is seemingly silent as to what the rule on this is, however, making this non-constexpr results in clang accepting the constructor.

Avi Kivity	16006949d0	logalloc: make migrator an object, not a function pointer ... The migrator tells lsa how to move an object when it is compacted. Currently it is a function pointer, which means we must know how to move the object at compile time. Making it an object allows us to build the migration function at runtime, making it suitable for runtime-defined types (such as tuples and user-defined types). In the future, we may also store the size there for fixed-size types, reducing lsa overhead. C++ variable templates would have made this patch smaller, but unfortunately they are only supported on gcc 5+.	2015-10-21 11:24:56 +02:00

Tomasz Grabiec	81d81c81f2	utils: managed_vector: Make copy constructor exception-safe ... Copying values may throw (std::bad_alloc for example), which will result in a leak because destructor will not be called when constructor throws. May manifest as the following assertion failure: utils/logalloc.cc:672: virtual logalloc::region_impl::~region_impl(): Assertion `_active->is_empty()' failed.	2015-09-06 21:24:58 +02:00
