    Memory Allocation

    Rationale: HotSpot often uses "resource" or "arena" allocation. Even where heap allocation is used, the standard global functions are avoided in favor of wrappers around malloc and free that support the VM's Native Memory Tracking (NMT) feature. Typically, uses of the global operator new are inadvertent and therefore often associated with memory leaks.

    Native memory allocation failures are often treated as non-recoverable. The place where "out of memory" is (first) detected may be an innocent bystander, unrelated to the actual culprit.

    Due to bugs in certain (very old) compilers, there is widespread use of enums and avoidance of in-class initialization of static integral constant members. Compilers having such bugs are no longer supported. Except where an enum is semantically appropriate, new code should use integral constants.

    thread_local

    -

    Do not use thread_local (n2659); instead, use the HotSpot macro THREAD_LOCAL. The initializer must be a constant expression.

    -

    As was discussed in the review for JDK-8230877, thread_local allows dynamic initialization and destruction semantics. However, that support requires a run-time penalty for references to non-function-local thread_local variables defined in a different translation unit, even if they don't need dynamic initialization. Dynamic initialization and destruction of namespace-scoped thread local variables also has the same ordering problems as for ordinary namespace-scoped variables.

    +

    Avoid use of thread_local (n2659); and instead, use the HotSpot macro THREAD_LOCAL, for which the initializer must be a constant expression. When thread_local must be used, use the Hotspot macro APPROVED_CPP_THREAD_LOCAL to indicate that the use has been given appropriate consideration.

Dynamic initialization and destruction of non-local thread_local variables also has the same ordering problems as for ordinary non-local variables. So we avoid use of thread_local in general, limiting its use to only those cases where dynamic initialization or destruction are essential. See JDK-8282469 for further discussion.

    nullptr

    Prefer nullptr (n2431) to NULL. Don't use (constexpr or literal) 0 for pointers.

    For historical reasons there are widespread uses of both NULL and of integer 0 as a pointer value.
