MSVC learned to not emit unreferenced symbols with internal linkage and the
hooks were defined in unnamed namespace which forces internal linkage, even if
you mark a variable `extern`.
Since Boost does not have a stable ABI, does not mangle the namespace with
the version, and the hooks are in `boost` namespace (`boost::on_*`) -- there is
no point in trying to hide some symbols because mixing different versions of
boost static libraries will not work already.
I also renamed the `__xl_ca` variable for consistency and because using double
underscored identifiers is forbidden. (`[lex.name]/3`)
The `extern const` is for verbosity and because they are indeed const (it is
done via pragma already).
* Re-fixed the EINTR bug that exists in some pthreads implementations.
It was originally fixed in https://svn.boost.org/trac10/ticket/6200 and
was accidentally disabled in 5b209c2e83.
* Made sure that the fix for the EINTR bug was consistently applied to
all code in the library.
* Made sure that all pthread_mutex_*() and pthread_cond_*() function
calls in the library were consistently decorated with
BOOST_THREAD_DISABLE_THREAD_SAFETY_ANALYSIS.
Instead of wrapping a default or user provided destructor into a virtual
class and placing it into a shared_ptr it is now stored directly with
an elided type, to not introduce UB it is not called directly but through
a helper function which casts it back to the original type before calling.
Periodic refreshes make sure that the 32-bit GetTickCount wraparounds are
properly counted even if the user doesn't call GetTickCount64 for extended
periods of time.
- Added no_interruption_point::sleep() functions to pthreads to be
consistent with Windows.
- Fixed an issue where the no_interruption_point::sleep_*() functions
were still interruptible on Windows.
- Fixed build failures on Windows. The timespec struct is not supported by older versions of Visual Studio. I changed the internal representation inside of the *_timespec_timepoint classes to a boost::intmax_t representing the number of nanoseconds since the epoch.
- Fixed some functions that wouldn't execute at all if they were provided a negative time duration or an absolute time that was in the past. From what I understand, they should instead execute once and then return immediately.
- Moved pthread/timespec.hpp to detail/timespec.hpp.
- Deleted detail/internal_clock.hpp and moved the seven relevant lines into detail/timespec.hpp. This keeps all of the internal clock declarations in one place.
- Renamed thread_detail::internal_clock_t to detail::internal_chrono_clock to be consistent with and yet clearly differentiated from detail::internal_timespec_clock.
- Removed "using namespace chrono" to eliminate ambiguious namespace resolution when referencing detail::internal_chrono_clock.
- Re-enabled a few tests on Windows that had previously been disabled. I want to see whether or not they still need to be disabled.
* Added a constructor to timespec_duration, real_timespec_timepoint, and mono_timespec_timepoint that takes an intmax_t representing the number of nanoseconds in the timespec.
* Added a getNs() function to timespec_duration, real_timespec_timepoint, and mono_timespec_timepoint that returns an intmax_t representing the number of nanoseconds in the timespec.
* Added a timespec_milliseconds() function that takes an integer representing milliseconds and returns a timespec_duration.
* Removed some unnecessary BOOST_SYMBOL_VISIBLE declarations.
* Removed the unnecessary d100 variable declarations.
* Deleted a couple of unnecessary calls to internal_clock_t::now() in v2/thread.hpp.
* Deleted the hidden::sleep_until() functions, which are no longer being used.
* Deleted the condition_variable::do_wait_for() function, which is no longer being used.
* Deleted the sleep_mutex and sleep_condition variables in pthread/thread_data.hpp, which are no longer being used.
* Fixed the interruption-point versions of sleep_for/sleep_until() to always use condition variables.
* Fixed the no-interruption-point versions of sleep_for/sleep_until() to use pthread_delay_np or nanosleep whenever possible.
* Updated hidden::sleep_for() to always use a condition variable.
* Updated no_interruption_point::hidden::sleep_for() to use pthread_delay_np or nanosleep whenever possible.
In MSVC-9 MFC sources, _pRawDllMain and ExtRawDllMain accept HINSTANCE as
the first argument, not HANDLE. In strict mode these are different types,
which creates the potential for ODR errors. This commit resolves that
inconsistency.
Resolves https://svn.boost.org/trac10/ticket/12323.
This should fix startup of executables statically linked with Boost.Thread
because of undefined return value of the thread/process startup hooks.
Should fix https://svn.boost.org/trac10/ticket/12730.
