2023-01-13libstdc++: Do not include <system_error> in concurrency headersJonathan Wakely1-0/+1
The <condition_variable>, <mutex>, and <shared_mutex> headers use std::errc constants, but don't use std::system_error itself. They only use the __throw_system_error(int) function, which is defined in <bits/functexcept.h>. By including the header for the errc constants instead of the whole of <system_error> we avoid depending on the whole std::string definition. libstdc++-v3/ChangeLog: * include/bits/std_mutex.h: Remove <system_error> include. * include/std/condition_variable: Add <bits/error_constants.h> include. * include/std/mutex: Likewise. * include/std/shared_mutex: Likewise.

2020-10-22libstdc++: Only include <condition_variable> in <shared_mutex> if neededJonathan Wakely1-6/+11
The <condition_variable> header is not small, so <shared_mutex> should not include it unless it actually needs std::condition_variable, which is only the case when we don't have pthread_rwlock_t and the POSIX Timers option. The <shared_mutex> header would be even smaller if we had a header for std::condition_variable (separate from std::condition_variable_any). That's already planned for a future change. And <memory_resource> would be even smaller if it was possible to get std::shared_mutex without std::shared_timed_mutex (which depends on <chrono>). For that to be effective, the synchronized_pool_resource would have to create its own simpler version of std::shared_lock without the timed waiting functions. I have no plans to do that. libstdc++-v3/ChangeLog: * include/std/shared_mutex: Only include <condition_variable> when pthread_rwlock_t and POSIX timers are not available.

2020-03-25libstdc++: Define and use chrono::is_clock for C++20Jonathan Wakely1-0/+6
For C++20 the wait_until members of mutexes and condition variables are required to be ill-formed if given a clock that doesn't meet the requirements for a clock type. To implement that requirement this patch adds static assertions using the chrono::is_clock trait, and defines that trait. To avoid expensive checks for the common cases, the trait (and associated variable template) are explicitly specialized for the standard clock types.

2019-12-02libstdc++: Fix try_lock_until and try_lock_shared_until on arbitrary clockMike Crowe1-4/+20
This is the equivalent to PR libstdc++/91906, but for shared_mutex. A non-standard clock may tick more slowly than std::chrono::steady_clock. This means that we risk returning false early when the specified timeout may not have expired. This can be avoided by looping until the timeout time as reported by the non-standard clock has been reached. Unfortunately, we have no way to tell whether the non-standard clock ticks more quickly that std::chrono::steady_clock. If it does then we risk returning later than would be expected, but that is unavoidable without waking up periodically to check, which would be rather too expensive. François Dumont pointed out[1] a flaw in an earlier version of this patch that revealed a hole in the test coverage, so I've added a new test that try_lock_until acts as try_lock if the timeout has already expired.

2019-12-02libstdc++: Add full steady_clock support to shared_timed_mutexMike Crowe1-21/+80
The pthread_rwlock_clockrdlock and pthread_rwlock_clockwrlock functions were added to glibc in v2.30. They have also been added to Android Bionic. If these functions are available in the C library then they can be used to implement shared_timed_mutex::try_lock_until, shared_timed_mutex::try_lock_for, shared_timed_mutex::try_lock_shared_until and shared_timed_mutex::try_lock_shared_for so that they are no longer unaffected by the system clock being warped. (This is the shared_mutex equivalent of PR libstdc++/78237 for mutex.) If the new functions are available then steady_clock is deemed to be the "best" clock available which means that it is used for the relative try_lock_for calls and absolute try_lock_until calls using steady_clock and user-defined clocks. It's not possible to have _GLIBCXX_USE_PTHREAD_RWLOCK_CLOCKLOCK defined without _GLIBCXX_USE_PTHREAD_RWLOCK_T, so the requirement that the clock be the same as condition_variable is maintained. Calls explicitly using system_clock (aka high_resolution_clock) continue to use CLOCK_REALTIME via the old pthread_rwlock_timedrdlock and pthread_rwlock_timedwrlock functions. If the new functions are not available then system_clock is deemed to be the "best" clock available which means that the previous suboptimal behaviour remains. Additionally, the user-defined clock used with shared_timed_mutex::try_lock_for and shared_mutex::try_lock_shared_for may have higher precision than __clock_t. We may need to round the duration up to ensure that the timeout is long enough.
