* 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

* Reorganize InlineData into an inner Rep structure.Gravatar Martijn Vels2022-10-13
| | | | | | | | | | | | | | | | This moves inlined code around a bit without changing anything bar the names of things. The purpose for all this is that it greatly simplifies the process of adding memory poisining to Cord / InlineData. InlineData can have scoped poison / unpoison regions around the interface, calling into rep for the 'real code'. 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.

* CMake: Remove check_target calls which can be problematic in case of ↵Gravatar Abseil Team2022-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | dependency cycle Also renames `_target_compile_features_if_available` CMake function to `_absl_target_compile_features_if_available` since CMake's function namespace is global. The dependency cycle can occur if absl is configured with test helpers enabled, and googletest is configured to use absl. In the case that both projects are being built from source via FetchContent with OVERRIDE_FIND_PACKAGE, depending on the order in which the two projects are added to the build, the check_target calls may fail even though the build would have otherwise succeeded. The existing `check_target` calls seem to have been originally added to detect missing gtest targets when the `GTest::` prefix was not yet in use. For target names without "::", CMake does not warn if they are undefined, and just assumes they refer to system library names. However, CMake does fail during build generation if a target name with "::" is missing; thus the check_taget calls are redundant.
