* Force a conservative allocation for pointers to methods in Condition objects.Gravatar Abseil Team2022-11-07
| | | | | | | | | | | In order for Condition to work on Microsoft platforms, it has to store pointers to methods that are larger than we usually expect. MSVC pointers to methods from class hierarchies that employ multiple inheritance or virtual inheritance are strictly larger than pointers to methods in class hierarchies that only employ single inheritance. This change introduces an opaque declaration of a class, which is not fulfilled. This declaration is used to calculate the size of the Condition method pointer allocation. Because the declaration is of unspecified inheritance, the compiler is forced to use a conservatively large allocation, which will thereby accommodate all method pointer sizes. Because the `method_` and `function_` callbacks are only populated in mutually exclusive conditions, they can be allowed to take up the same space in the Condition object. This change combines the `method_` and `function_` fields and renames the new field to `callback_`. The constructor logic is updated to reflect the new field.

* | Mutex: Fix stall on single-core systemsGravatar Abseil Team2022-10-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On single-core systems, a thread could be preempted while holding an absl::Mutex, or even worse, the spin lock. If a FIFO thread wakes up and tries to acquire this lock, it might not be able to yield() to the sleeping thread. Within MutexDelay(), a yield() and a sleep(10us) are used to yield the CPU. The yield() would do nothing if the calling thread holds the highest priority in the system. The 10us sleep() may not be able to reach the scheduler either, if the system is slow enough. This code path is known to be reachable in the following scenarios: - a FIFO thread calls LockSlowLoop() with spin lock held by a normal thread - a FIFO thread calls LockWhen*() with the Mutex held by a normal thread for a long time - a FIFO thread calls Await*(), releases the Mutex to be held by a normal thread for a long time This CL adds a mutex global for the sleep time, and sets it using the return time of the a yield() call. Yield() must reach the scheduler even when it fails to yield to anyone, and would allow sleep() to do the same. A small constant multiplier (5) is also applied to overcome uncontrollable factors in the runtime and help sleep() to consistently yield to another thread. Upper and lower bounds for the sleep time is also controlled to block any unreasonable values. PiperOrigin-RevId: 483459711 Change-Id: I14efadbadaf9244a2462f377b515147bda651c89

I.e.: Rep::as_chars() { return &inline_data[1]; } InlineData::as_chars() { Unpoisoned self(this); return rep_.as_chars(); } Likewise, it greatly simplifies intercepting the code for constructors, copy constructors and operator= logic.
